Bucket elevators and vibration elevator and other lifting equipment maintenance considerations

As technology continues to introduce and improve production upgrade machinery to reach a very high specification , has been the demand can be satisfied with the present and

future needs of the construction norms, domestic foundation engineering and construction without bucket elevator equipment, system is a mechanical professional conduct essential

equipment. The feed is

Bucket elevator one of the most important 90 degree conveyor job process , feed is not reasonable not only affects the function of bucket elevators , and right after the sequence operations (

promotion and discharge process ) will attack chain reaction.

For grain, oil, feed mill workshop of bucket chain conveyor elevator feed forward feeding method , reverse feed and bi-directional feed , select the feed method which should speed of thought .

1 , when the lifting speed of the belt and the material flow into the base material when the flow rate are compared hours, usually used reverse feed bucket inside scoop on the

part of the base material and then filled directly from the inlet part of the material , which is fill factor conducive to progress.

2, if enhance the speed and flow of material with the base material when the flow rate is relatively large , the material impact on the larger bucket , reverse feed not only

fill factor affecting the progress of , and additionally increase the power consumption, in this case can be a forward feed .

3, if the fill factor is not easy to reach the required value , presenting " value " falters , then the feed can be bi-directional . Needs to clarify the grain, oil, feed mill

workshop of bucket elevator feeding method is very likely by the technical processes, technology planning the resolutions.

Vibration protection hoist capable of extensive analysis we carried out , surely we should also know how to protect the equipment, but does not know in detail the process of

implementation .

The first operation vibration hoist hoist equipment vibration , do not be afraid to waste money, see the end of all the production line without abnormal , boot empty load

operation eight hours , you are not mistaken , is to empty the load operation , that is to what materials does not increase , idling.

Why should we do ? Like just bought a new computer to the same end , we must first look at the boot operation , while not identical vibration hoist is in the empty -load

operation process, our operating personnel to stand next to , to keep the lubricating oil filling equipment increase next view all connected

Contacts are not reliable, load trial operation feed size of various models in strict accordance with the standard requirements , prohibited materials into greater delineation ;

Uniform feeding after another , the water content is not less than 10-15 % ( according to the material is not the same ) , feeding reaches new TB longitudinal vibration hoist

full load suspension ; load trial operation time 8-24 hours. New vibration hoist feed size stringent demands on delimitation , demarcation prohibit more than materials

Into the device , otherwise , it will cause vibration hoist accessories new impeller imbalances and excesses impeller wear , and even the formation of blocking the impeller

channel and the central feeding tube, the new vibration hoist can not work properly, if there is a slot somethin attack, we must first intercept power , and other host

After the job is aborted completely , then remove the card slot of the material , completely not in the device operating time, the device produced artificially disturbed .

Spot welding method roller conveyor

Spot welding is to be worn at the welding filler recess . Simple and practical method roller conveyor , without affecting production , automated sorting machine and the surfacing parts of the hardness

and good wear resistance , roller conveyor Incline Belt conveyor drawback is only suitable for the roll and good solderability ( eg steel roll ) .
Surfacing should note the following:
Lift the drum roll bar to select the appropriate surfacing to use the heap and heap 266 256 is appropriate.
Lifts should be chosen drum roller surfacing of small diameter , low current welding specifications , stratified surfacing. This reduces the thermal stress , to avoid severe

deformation and cracking

Three roller conveyor performance and structure comparison

     Roller conveyor materials are carbon steel, stainless steel , steel, can not only improve the quality of the belt conveyor manufacturer can guarantee long-term stability , but also that the majority of manufacturers to bring economic cost savings , eliminating many of the production line troubles . Production line conveyor belt

The main functions are: transportation , drying and assistance adhesive cardboard, so the belt will become part of the production process determines the level of product quality is one of the most critical processes . Production line and production process on the portable conveyor belt requirement has three characteristics:
     Surface is flat and firm structure : belt requirement is the quality of rugged, high-density, scalable geometric stability, surface insensitive to transfer the long-term use can remain flat , thus less susceptible to residual adhesives and other dirt impact, while sturdy You can also guarantee quality

Belt does not permit off-line , can not afford layer is not uneven , so that after bonding of cardboard will be uniform, smooth and more perfect , to avoid blisters and other undesirable quality phenomena occur . Acupuncture cotton conveyor belts and different, mainly with acupuncture needling process produced by chemical synthesis

Forming, with the initial surface smooth, soft, and cardboard favor the contact surface affinity , but the weakness of the surface with a needle too sensitive , easy off-line, from the floor to be contaminated and difficult to clean and easy maintenance, wear resistance not strong enough, stretching geometry is not stable enough . Belt mainly by

Woven cotton fibers and synthetic fibers and enhance high-density, thus ensuring the quality and with a sturdy flat surface, thereby significantly improve the wear resistance and long term heat stability.
     Drying , air permeability : The adhesive cardboard belt production process requires evaporation to absorb moisture vapor and the ability of synthetic chemical fiber poor moisture absorption and drying , the needle made ??of a synthetic fiber with a porosity of acupuncture higher than the cotton fibers mainly woven

Cotton belt , from this point of view it also strengthened its moisture and evaporation . The physical properties of cotton fiber material relative moisture drying properties of chemical fibers will have an advantage . From absorbing vapor / moisture evaporation relative value test cf results, significantly higher than the needle cotton belt

Thorn belt . On the whole , dry , breathable stronger.

Belt conveyor features and layout of the form

    As a class object Branch conveying tobacco Airport conveyor has some of the features are:
( A ) a very small amount of material handling
( 2 ) belt load is low
( 3 ) slow belt
( 4 ) Belt thickness is very thin, but good flexibility
( 5 ) the length of the shorter belt conveyor
( 6 ) multi-use machine type products
( 7 ) does not use groove roller , instead of using flat roller .
    roller conveyor belt scale is not suitable for installation with belt conveyor belt conveyor with variable length , variable angle belt conveyor belt conveyor belt unloading

car with concave arc of the curve segment belt conveyors , portable belt conveyor, belt conveyor rope suspended

Machine with steel cord belt conveyor belt and so on.
    Suitable for mounting electronic belt conveyor belt with a horizontal belt conveyors, constant inclination angle belt conveyors, belt curve segment concave arc belt

conveyor.
    The most suitable installation electronic belt is designed to meet the requirements of the design and complemented by weighing belt conveyor transport function , rather than

to meet the transport function design combined with the weighing belt conveyor.

On the conveyor belt deviation encountered the phenomenon should carefully analyze the reasons

Conveyor running process will inevitably occur due to various reasons often belt deviation phenomenon, which not only can cause leakage of material , equipment, non-normal wear

and tear , but also reduce productivity , but also affect the whole equipment work. Therefore, the correct judgments

A Pipe conveyor belt deviation reasons but also timely to be excluded , is a very important and difficult task .
Deviation rule is: "run do not run loose tight " "run do not run high- low" , " do not run after running in front ." If both sides of the tightness of the belt is not the same,

then the tight side of the belt to move ; if the level is not the same on both sides of the belt , then the belt will move to the high side ; if the roller frame

Other device is not installed in the vertical section of the belt running direction , but on the front end , the rear end ( along the belt running direction ) , the belt will

move toward the rear end .
Deviation of the drum at the belt , mainly from the following two aspects to adjust : First roller bearing ends of the height of error, but also the drum axis is not level , it

will also cause deviation industrial conveyor , capable of bearing plus less shim to adjust the levelness of the drum axis . Second, roll

Cylinder centerline is not perpendicular to the center line of the conveyor can be adjusted bearing position , but also to ensure the conveyor roller centerline and

perpendicular to the centerline .
Belt deviation is a tricky thing, when detuning belt deviation should carefully analyze the reasons for , and then carefully observed , in order to remedy , to explore in

practice , gain experience. At the same time , but also to strengthen the belt routine maintenance and repair work ,

Can eliminate or reduce the belt deviation phenomenon, improve productivity and increase economic efficiency will play a better role .

How to extend the belt conveyor belt life

Conveyor localized damage repair techniques to prolong life. ( 1 ) local cold sticky , cold glue adhesive longitudinal T2 to fill a crack block ( requires special glue gun ) .

These two forces is the ' law distinctions, - Oxygen is less human and material resources , but also has good resistance to abrasion and reinforcement

Performance , so recovery time is shorter , the disadvantage is that the environmental requirements are particularly high , the belt surface can not be restored to the original

half-integer requirements ; ( 2 ) gravity conveyor spray repair techniques . This technology is the liquid material after several special mixing equipment , high pressure spray to the

skin

Belt worn surface . May need to spray a certain thickness of wear layer. Curing time is very short, more suitable for local wear even into a film , the effect is good, but the

drawback is the need special equipment. ( 3 ) local thermal curing ; ( 4 ) local cold splash , the product is a blessing America World listless (1sfline)

Technical liquid polymer composite restorative materials , DT De Fukang , etc., but need to indole at room temperature of about 12h ;
Either concave gravity skatewheel conveyor pulley claw at the transition . Practice can be confirmed , rope conveyor transverse strength is insufficient, startup, denounced belt pulley causing

local stress will be too large , resulting in torn conveyor belt, pulley umbrella of the Ministry will be music to music with drum can solve this

Problem .
Improved conveyor hopper off . Improved drop hopper conveyor , conveyor belt is to prevent premature failure of one of effective measures . Will improve the transfer belt down

at the hopper , the ability to increase it through three times the foreign body , long, large foreign body in the transportation process is not easy stuck in the funnel

Between the wall and the belt , while also reducing the probability of foreign torn belt . Off the lead at the feed hopper apron , making and conveyor belt running along the

direction of the gap bigger , so to solve the coal , Eli blocks stuck in the conveyor belt and the language problem between the plates , eliminating the six I This caused output

Belt damage. Larger drop hopper baffle installed inside the buffer , but also to avoid the direct impact of the material conveyor .

Feed bucket elevator rationality

Feed bucket elevator is the main one working process, feed is reasonable not only affect the performance of bucket elevators, but also after the sequence work (promotion and

discharge process) will have a ripple effect. Thus, studies and efforts to implement reasonable feed has very important significance.
Measure the feed bucket elevator is reasonable, in general, consider two aspects: First, fill factor; Second, feed resistance. As we all know, of course, is feeding resistance

as small as possible, and fill factor is  Elevator conveyor  not necessarily better. In the design and field operation hoist when it reasonable feed

, Is essentially filled with the appropriate coefficients, feed resistance.
1 filled with an appropriate coefficient
Fill factor is too small (too small bucket interior quantity) is a typical "big horse car" phenomenon; fill factor too big and are not economical, because it is possible to

enhance the machine and the unloading process will be a "backflow" . Thus, the meaning of the appropriate coefficient  chain conveyor filled: each of the other components to work

Conditions (such as raising the belt tension, wheel diameter and speed, etc.), bucket seat loaded in the machine after upgrading the material can successfully discharged from

the discharge port without generating the maximum fill factor reflux.
Fill factor affecting many factors, but can be summed up in the following aspects:
(A) feeding method
For grain, oil, feed mill workshop of bucket elevator feed forward manner with feed, reverse feed and bi-feeding, choose which feeding method should consider speed. When

upgrading the speed and flow of material with the base material when the flow rate are relatively small, generally used in reverse into

Materials, bucket inside scoop on the part of the base material and then filled directly from the inlet part of the material, which is conducive to the improvement of fill

factor. If you upgrade the speed and flow of material with the base material when the flow rate is relatively large, the material impact on the larger bucket, reverse feed is

not

Affects only filled coefficient improved, and additionally increase the power consumption can be used in this case the forward feed. If you fill factor is not easy to achieve

the required value, the "yield" falters, then the feed can be bi-directional. It should be noted that grain, oil, feed mill workshop

The bucket elevator feeding method is likely by the process, process layout of the decision.
(2) internal friction coefficient and the bottom wheel speed
Bucket seat when loading the machine, in theory, the material surface conform to the pole, as the center of the logarithmic spiral composed of logarithmic spiral surface

equations. Calculation, mapping show that: the internal friction coefficient of the material which filled coefficient; bottom wheel speed is slow, the material inside the bucket

coefficient

.
(3) bucket shape
In practice, it was found that the shape of bucket filled with impact factor. To increase the fill factor, but also conducive to the discharge, regardless of what type of

bucket, their basic form are large mouth with small, low internal high outside, bottom radiate round (no sharp corners). For enhancing the lightweight materials such as Google

Shell, bran, etc., in order to drain away the bucket of feed air to facilitate the bucket bottom opening (about 2 ~ 5mm in diameter), which is perforated bucket.
(4) feed flow
Filled with feed flow coefficient affecting one of the determinants. Some hoist mounted at the inlet feed flapper, to adjust the feed inlet cross-sectional area; Some hoist is

equipped with a buffer feeding means for regulating the feed flow.
Above mentioned factors influence coefficient filled grouped into two categories: one for on-site operation of uncontrollable factors, such as feeding method determined by the

designer, was promoted internal friction coefficient depends on the material, the bottom wheel speed and head round the same speed; second category is the uncontrollable factors

that the job site

Reliance on manual adjustment to control the feed flow rate as described above. On-site operation, adjust feed rate to control fill factor of great significance.
2 The feed resistance factors
Feeding resistance factors are mainly the following two aspects.
(A) the resistance movement
Bucket seat while loading the machine while running, its resistance on the one hand the performance of the feed bucket materials and friction between the material and the

friction between the inner wall of the base, the friction between the material and the material; hand , is the driving force of the material bucket. They are both running in the

material bucket

Proportional to the distance.
(2) material impact on the bucket
When the reverse feed, there is a direct part of the material is filled into the bucket and going, so that the material is produced on the bucket wallop. If the speed of the

belt and the material to enhance the flow of material to the base when the flow rate of greater material impact on the bucket is also larger, feeding resistance increased

accordingly.
