Improved screw conveyor

With China 's rapid economic development , the demand for cement is growing. Cement production, raw material conveying Screw conveyor is one of the devices . Screw in the

application hanging bearing often occur at blocking material, the flash conditions affecting production , economic efficiency decreases. For screw conveyor

Machine to analyze this situation : the food conveyor helical blade hanging bearing is that the role of the place, where not only will accumulate a lot of material , but also

in the box at the bottom of a lot of hard grinding granular material deposition , which is difficult to broken iron grain , coarse particulate material content of more, and

Very dense , so that both ends of the conveyor screw shaft friction blades severely , both ends of the blades wear more severe ; screw conveyor hanging bearing increased wear

and reduce service life. To solve the above problem, screw conveyor manufacturing has done in the following improvements:

At both ends of the screw shaft screw conveyor welding two helical blades , to strengthen the hanging bearing thrust plot material . Screw conveyor screw shaft rotation , thrust

generated twice the material , reducing the area of ​​the hanging bearing material, will not happen again blocking material, the flash phenomenon . Screw

The hanging bearing on the improvement in the process : hanging bearing wear-resistant materials ( such as iron ) made ​​; or steel castings , steel castings bore quenching,

coupled with the cylindrical axis of the middle section of quenching, after quenching grinding ; or hanging bearing bore and shaft coupling covered cylindrical electrode wear a

tie

Enhance the abrasion resistance , extending bearing life hanging . After improvement , screw conveyor hanging double the life of bearings , greatly reducing maintenance costs,

while reducing the cost of production of cement , increase economic efficiency.

Easy maintenance.

Roller conveyor for conveying the bottom is flat goods, mainly by the drive roller, rack, bracket, drive unit and other components. With throughput, fast, running light, to

achieve multi-species collinear shunt transport characteristics.

Structure: there is power from the drive into the formal, non-powered, electric rollers, etc., according to the layout is divided into horizontal conveyor, inclined conveyor and

turning conveyor.

Transportation equipment according to the classification used for purposes

1, bulk material handling equipment (eg: belt \ Screw \ bucket elevators \ inclined conveyor)
(A) by a conveyor belt tensioning device drives the central structure and composition of the industrial conveyor as towing and carrying member, so as to continuously fed into pieces

scattered and fragmentary materials or goods.

Friction drive conveyor is a continuous manner for material transport machinery. Apply it, the material can be transported in a certain line, the feed point from the initial to

the final discharge point between the formation of a material transfer processes. It can be granular material Telescoping conveyors can also be

For a delivery of items. In addition to the purely material handling, but also with various industrial enterprises in the production process requirements matching process, the

formation of the rhythmic flow transport line. So conveyor is widely used in a variety of modern industrial enterprises.

In the underground mine workings, mine ground transportation systems, open pit and processing plant, widely applied conveyor. It is used for horizontal transport or inclined

transportation.

Universal conveyor from the conveyor belt, roller, roller and the drive, brakes, tension, bend, loading, unloading, cleaning and other equipment components.

① conveyor

Commonly used with two kinds of rubber bands and plastic. Rubber band for working environment temperature -15 ~ 40 ° C between. Material temperature does not exceed 50 ° C.

Upward transport of Granules inclination 12 ° ~ 24 °. Available for large transmission angle tread rubber band. Plastic belt with oil, acid,

Alkali, etc., but for the poor adaptability to climate, slippery and aging. Bandwidth is the main technical parameters of belt conveyor.

② roller

Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap angle of 350 °) and multi-cylinder (for power) and so on. There trough roller, flat-shaped

roller, spherical roller, buffer roller. Trough roller (2 to 5 by the roller composition) supporting bearing branches to lose

Send granular materials; aligning roller to adjust the lateral position with, to avoid deviation; buffer roller mounted in place by the material in order to reduce the impact of

material on the belt.

③ drum

Minute drive rollers and bend pulley. Drive rollers are main components of power transmission. Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap

angle of 350 °) and multi-cylinder (for power) and so on.

④ tensioning device

Its role is to achieve the necessary belt tension, in order to avoid slipping on the drive roller, and to the conveyor belt between the deflection rollers ensure that the

required range.

The technical advantages of belt conveyor

The first is its reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants, steel mills and cement

conveying bulk materials, as well as loading and unloading of ships in ports all adopts belt conveyor. If the shutdown these occasions, the loss is enormous

. If necessary, take a class to a group of belt conveyor can work continuously.

Conveyor low power consumption. As the material almost no relative movement of the conveyor belt, not only the running resistance (about 1/3-1/5 scraper conveyor), but also the

wear and broken cargo are small, high productivity. These are conducive to lower production costs.

Conveyor belt conveyor line adaptable and flexible. Line length according to need. Short as a few meters, length up to 10km or more. Can be installed in a small tunnel, ground

transportation can also be set up in the region over the chaos and danger.

According to process requirements, can be very flexible belt from one or more points by the material can also be more or several sections to discharge. While simultaneously at

several points on the feeding conveyor (such as the Coal bunker conveyor) belt length direction or along either alike

Over uniform feeding device to feed conveyor, the belt has become a major transport route.

Coal stockpile conveyor can stockpile reclaimer roadway below, when necessary, but also to the heap of different materials are mixed. Materials may be simply discharged from the

conveyor head, but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point discharge.

(2) commonly known as the auger screw conveyor is suitable for granular or powdered materials horizontal conveyor, inclined conveyor, vertical transportation and other forms.

Transmission distance varies according to deformity, usually from 2 meters to 70 meters.

Conveying principle: rotating spiral blade for screw conveyor passage of the material transported. So that the material does not rotate together with the screw conveyor blades

is the material force of its own weight and the frictional resistance of the material conveyor chassis.

Features: Screw rotating shaft is welded spiral blades, blade face delivery of materials based on a solid surface different type, belt type face, leaves and other types of face.

Screw conveyor screw axis in the direction of movement of the material with the thrust bearing to the terminal with the material to spiral

Axial reaction force, the captain longer, should be added to intermediate hanger bearings.

Two screw conveyor is to have two rotating blades were welded with the rotary shaft screw conveyor. To put it plainly, is to two conveyor organic combination, consisting of a

screw conveyor.

Screw rotation axis of rotation, determines the conveying direction of the material, but generally in the design of the screw conveyor are transported in accordance with the

individual blades of rotation. When the reverse transport, it will greatly reduce the service life of the conveyor.

(3) the use of bucket elevators uniform traction member fixedly connected to the series of unprovoked hopper, vertical continuous upgrading of materials handling machinery.

Bucket elevator with transmission capacity, high hoisting height, stable and reliable, long life and significant advantages, its main properties and parameters in line with
