Measures for the effective operation of scraper conveyor

Measures for the effective operation of a scraper conveyor
1 . Maintaining scraper conveyor running in calm conditions straight
Scraper conveyor in both the horizontal and vertical directions are allowed a certain degree of 90 degree turn conveyor bending ( which is to adapt the work
Surface transportation and roadway design , and does not refer to any of the upper and lower body and horizontal bending is reasonable ) , but
Permissible bending there are certain limits. If the scraper conveyor Abduction " chicane ", the joint will bend chute
Angle is too large , resulting chute connections damaged by excessive force . Damage and lost connections after chute , chute
Lost control joints , bending joints appeared gap between the chute , coal tank leak in the 90 degree conveyor end , will increase the run
Resistance or blockage caused the accident . If the conveyor laying uneven , then the blade and chute chute lap joints
Wear and tear , increased transportation ? Line resistance and shorten life , and it will lead to the end of the shearer cutting face
Board and make it uneven .
2 . Enhance the effective running time
Throughput scraper conveyor is run by its efficiency and working time decision. In a certain situation loading
Under conditions of work , the higher utilization of equipment operation , greater throughput , the performance of the scraper conveyor full
Play a beneficial , is an effective way to improve the yield and economic benefit . Therefore, you want to do everything possible to run
Reduce downtime . Generally not allowed scraper conveyor -load operation , because not only shorten the effective operation of load
OK time, but also caused a waste of electricity and mechanical wear invalid . If the scraper conveyor at runtime hair
Fails, as long as the fault is no longer expanding range should try to take a temporary repair tools, equipment continue to maintain
Operation will be postponed to deal with incidents within classes or shift maintenance spare time , avoid downtime , extended
Effective long running time .
3 . Load reasonable
Load scraper conveyor should be possible to achieve rating to its full production capacity. Conveyor
The charging excessive overflow will feed chute and outside the labor spent in vain and power , and cause equipment over
Upload and mechanical damage ; charging too little , so that the scraper conveyor capacity can not give full play to increase exercise in futility loss
, It is not economical. In addition, the uniformity of the load is also very important, which is not only conducive to the economic operation of the device ,
And extend the useful life of the scraper conveyor components.
4 . Strengthen supply management
Power supply voltage drop can not be overrun because of the torque of the motor is proportional to the square of the same voltage , power
Depression can cause difficulty in starting the motor , fever and even burn . So, to shorten as much as possible from the power supply
Away , so that the power transformer as close to the device.
5 . Timely maintenance and repair
By good standard scraper conveyor for maintenance and repair and maintain equipment in good condition and in good working
For the state.

Roller conveyor belt Precautions

   With the roller conveyor belt in industrial production in popularity , more variety , high-performance , lightweight , versatile, long life the manufacturers concerned about

several aspects . In industrial production , the proper use of conveyor belt is particularly important , the bucket elevators belt in use should note the following:
1 Prevent roller covered by material , causing rotation ineffective to prevent leakage of material between the card in the drum and the tape , note the lubrication of conveyor

belt moving parts , but not oil belt ;
(2) prevent the belt load start ;
3 conveyor deviation occurs , drag chain conveyor should take timely measures to correct ;
4 found conveyor local damage , the application of rayon timely repair to avoid expanding ;
5 to avoid being conveyor rack , pillars or massive block of material , to prevent misfortune to scratch the rip .

Roller conveyor belt feeding heavy start-up requirements

    When the roller conveyor is stopped for any reason with the material , and then start belong reload starts. Requirements for Telescopic belt conveyor drive can be started with a

heavy material . Drum machine starts with the material to be reloaded , the motor output torque , that is, to overcome the belt support rollers and wheels each of the following

The static friction between the shaft caused by the resistance torque , but also the material in the drum to overcome the downward force caused by the drag torque . The material

in the drum of the tension caused by the downward drag torque is constant. The static friction is more than the dynamic friction large , which makes for overcoming the static

friction

The initial starting torque , compared with the normal operation of the dynamic friction moment of resistance caused by a large number. So the drive must have a low speed and

high starting torque function. Actually boot process , since the drum elasticity , each roller is rotated in order by industrial belt conveyor successively , not both

Rotation. Even if the wheel turning up , because the speed is low , between the roller and the roller shaft poor lubrication , will be very astringent , the dynamic friction is

unstable, and therefore the starting torque low speed a certain fluctuations. But in the startup process, take some time to

So that all wheels are turning up the torque began to decline. Only up to a certain speed , improved lubrication , the torque fluctuations will be reduced. Therefore, such a

large low-speed starting torque , is the need to maintain a certain amount of time , generally at least a few seconds. And the roller length and the start

The minimum speed , and the belt elasticity and so on. And start the low speed, torque and speed fluctuations will be relatively large .

How to reduce the deviation phenomenon of belt conveyor

    Belt conveyor belt deviation runtime is the most common faults. To address such failures is important to note the dimensional accuracy of installation and daily maintenance.

There are several reasons for deviation, to be based on the difference between handling different reasons.

     1 Adjust the rubber belt conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the

manufacture of both sides of the mounting holes are worked into holes in order to adjust . The specific method is biased which side of the belt, roller

Group toward which side of the belt forward direction forward, backward, or the other side. Belt upward direction of deviation is lower roller group should be at the left, the

upper roller group moved to the right place.

     2 Install the self-aligning roller group aligning roller group has a variety of types, such as intermediate shaft type, four-link, vertical roller, etc., the principle is

the use of block or roller rotates in the direction in the horizontal plane lateral thrust block or generate the Automatic belt adjustment belt deviation reaches to the heart of

the purpose. General

The total length of the belt conveyor belt conveyor shorter or bidirectional operation using this method is more reasonable, because the shorter belt conveyor easier deviation

and not easy to adjust. And long Incline Belt conveyor is best not to use this method because the group aligning roller belt use would make

Useful life of a certain impact.

     3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because at least a belt

conveyor rollers 2 to 5, the installation location of all rollers of the belt conveyor must be perpendicular to the longitudinal direction of the center line,

If the skew is too large deviation bound to happen. Adjustment Method and its group of similar idlers. For the head drum as the drum belt deviation to the right, the right of

the bearing should be moved forward, the belt deviation to the left of the drum, the left bearing housing should be moved forward, also the corresponding

You can move left or right rear bearing housings after the shift. Rear roller adjustment method and the head drum opposite. After repeated adjustments until the belt transferred

to an ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.

Belt conveyor design features three large

1, work environment, status and condition
Need to consider every single day running of the time, frequency, belt service life, feeding and discharge methods.
Work environment conditions: ambient temperature, outdoor or indoor, environmental requirements, mobile or fixed, telescopic requirements.
2, the transmission line and the Belt conveyor problems
To consider in detail the size of transmission line, comprising: angle, the maximum length, lifting height; straight segment, the curve segment size; connection size.
Belt: Maximum sag requirements, simulated friction coefficient, friction coefficient, the safety factor.
3, the nature of the materials and throughput
Need to consider the specific nature of the material, including: bulk density, angle of repose, material particle size, largest block of the situation, the humidity of

materials, material wear resistance, adhesion and friction coefficient. Throughput, even when the material flow can be Conveyor System directly achieved throughput, material flow can test

uneven

Consideration given feed flow of basic statistics.

Conveyor trends

First, reduce the variety of conveyors in operation generated dust, noise and emissions.
Second, the conveyor structure to meet the material handling system automation and control for single requests. As used in automated sorting post office parcel trolley conveyor

sorting operation should meet the requirements.
Third, the expansion of the use of the vertical conveyor. Developments in high temperature, low temperature, corrosive, radioactive, flammable substances in the work environment, as well

as capable of delivering hot, easy to agglomerate, explosive, viscous material conveyor.
Fourth, to large-scale development. Large transmission capacity, including large-scale, large single length and large transmission angle and other aspects. Hydraulic conveyor

length reached 440 km or more. Belt conveyor length of nearly 15 km single, and has appeared composed by a number of Taiwan Contact B two places. "

Belt Conveyor Road. "Many countries are exploring long-distance, large capacity continuous transport of materials better 90 degree turn conveyor structure.
Fifth, reduce energy consumption in order to save energy, the field of conveyor technology has become an important aspect of research. Has one ton material handling energy

consumed by one kilometer conveyor selection as one important indicator.

Vibrating conveyor vibration facilities methods

The bulk solid materials vibrating hopper and unloading hopper to the stored materials. Provide vibration method may be hit with a heavy hammer to simply hit the side wall of

the hopper, or oscillating device with complex activator end positions. Vibration frequency can be 14 ~ 1300Hz, amplitude from near zero to large

At 60mm.
Vibration that can discharge capacity and material transmitted vibration reduction due to vibration of the bulk solid material strength. If the material is stored in an airtight

container, low-frequency vibration will make the material more dense; frequency vibration may cause the material may also lead to material bulk density, which is

And the corresponding amplitude of the nature of the material. It should be noted that, in the flow of the material required by vibration of occasions when the portable conveyor hopper

discharge port vibrations must not be closed. This results because of the material in any form will arch strength increases.
The hopper or bulk solid materials provide effective vibration There are two basic methods, namely silo wall vibrations and vibrations are directly stored materials.
Warehouse wall vibration
Hopper wall vibration is generally compressed air or by using the external hopper wall mounted electric vibrator to vibrate. A pneumatic piston vibrator type, electromagnetic

type and the eccentric rotary type (electrical or pneumatic operation).
Pneumatic piston vibrators rapping hammer with the outer surface of the hopper; electromagnetic vibrator has a similar effect, both the wall perpendicular to the vibration

bucket; eccentric rotary vibrator is Belt conveyor a vibrating device more expensive, generally life than short, compared with other types of vibrators, the need to stay low

Amplitude, high frequency operation, this device can be successfully used to move the material difficult.
Vibrator To properly placed in a position to produce the best results; selected amplitude and frequency of vibration must be sufficient to destroy the material arch. Under

normal circumstances, only be determined by experiment, usually affecting factors vibrator summarized as follows:
Type. About amplitude and frequency selection has some experience and law: that is, for raw materials, the general should adopt the low-frequency, high amplitude; For fine

powdery material is just the opposite. The specification shall be suitable hopper vibrator beveled plate rigidity and size.
Installation. Recommended hopper vibrator mounted on a steel reinforcing plate slope, and storage of the material as much as possible to increase the contact surface. Its

location in the "center of pressure" surface.
Vibration force. In most practical applications, the force necessary to apply part of the material silo cone weight of 1/10. If the density of the material is greater than

1440kg, the applied force is the weight of the cone part of the material 1/7; if the material density greater than 1920kg, the applied force is funnel portion was

Material weight of 1/5.

Conveyor Belt Conveyor Idler Analysis

Roller dysfunctional
An influencing factor dysfunctional roller
(1) roller manufacturing quality. Roller manufacturing problems mainly in the stiffness of the bearing seat belt is not enough, it is difficult to ensure accuracy of the idler

assembly, thereby constraining the roller operation flexibility.
(2) use of sealed lubrication and maintenance. Since the work environment is more severe Belt conveyor , generally site dust are large, bearing the seal forms flexibility for

running a great impact idlers, if seal is not good, it is easy to enter the dirt caused by roller bearings rotation is not flexible;

Also, if using the general bearing grease calcium base grease dries easily change color, you can not play a very good lubrication.
Idler running flexible approach
(A) in the manufacturing process of idlers guarantee the accuracy requirements, such as stamping bearing bore precision to achieve three, dimensional tolerances of the pipe

ends, concentricity and ovality must comply with GB, can not exceed the difference .
(2) sealed lubrication, in addition to manufacturing quality assurance, but to go with the better lubricating materials, such as using lithium grease, you can improve the

lubrication conditions, which prolong the service life of the roller is very necessary.
(3) using the radial ball bearing bearings, labyrinth seal plastic seal ring structure, both to ensure that the work roller reasonable force, and dust effects, resistance, and

easy assembly and disassembly, easy to maintain, effectively reduce the operating costs of the conveyor.

Cause slippage
The main reason is caused by skidding traction rollers reduce friction, overloaded or belt is jammed.
(1) roller damage, debris winding, burying materials and other reasons will not turn a lot of rollers, conveyor belts or fittings damaged by increased resistance to idlers,

conveyor serious deviation, such as excessive cargo were so excessive resistance caused by belt conveyor design belt slipping.
(2) belt use for some time due to plastic deformation and elongation, resulting in insufficient belt tension, friction and traction while reducing slippage.
(3) the conveyor belt and the drive roller contact surface immersed in mud, dust, friction coefficient declined sharply, thereby belt slippage.
Tape slippage prevention and treatment
(A) to strengthen the operation of conveyor management, control the amount of material to prohibit overloading operation. In addition, the normal use of slip protection device,

when the conveyor belt to slip through the sensor signals, automatic shutdown, ease of maintenance treatment.
