Brief Introduction of Belt conveyor Sweeper Type

Belt conveyor sweeper is one important part of belt conveyor, there are totally three types of belt conveyor sweeper: carbide belt conveyor sweeper, H type alloy rubber belt conveyor cleaner, P type alloy rubber belt conveyor cleaner.

1.Carbide belt conveyor sweeper

The Carbide belt conveyor sweeper is installed at the head pulley with the texture of scraper adopting carbide alloy. There are generally two types of it: single piece belt conveyor sweeper and double pieces belt conveyor sweeper. It realizes thoroughly material cleaning by changing the pressure beard by the conveying belt from the scraper through adjusting the balancing weight.

2.H type alloy rubber belt conveyor cleaner

It is installed at the head place of the pulley close to the conveying belt, principally applying the rubber elasticity. Meanwhile, the scraper texture is changed to Carbide scraper from rubber. It is placed close to the surface of the conveyor belt after the separation of the material with the conveyor belt.

3.P type alloy rubber belt conveyor cleaner

It is also installed at the head place of the pulley with the installation site similar to that of the spring sweeper. Besides, it shares the sweeping principle with the H type alloy rubber cleanser.

Step Analysis for the Installation Process of Belt Conveyor

There are seven steps in the installation process of belt conveyors, here are some tips analyzed by experts from PK machinery.

1 .Installation of the belt conveyor landing leg and intermediate frame

Please confirm the Centerline by using the theodolite before installation, then according to the centerline to find pile point location of each landing leg. If there is embedded iron, adjustment should be made according to the location of the embedded iron in order to facilitate the installation, each landing leg should be firmly welded with the embedded iron.

2 .Installation of the counterweight device

In this process we need to ensure the parallelism between the two force columns, and meanwhile ensure its verticality. Considering the safety, protective railings shall be immediately installed after finishing the installation of this device.

3 .Installation of the headstock, tailstock and drive device base

Firstly we should verify the install elevation and confirm the centerline. Then pay attention to the sizing block location and its number not more than 5 blocks. The thinner sizing block should be placed among the thicker ones and be firmly welded.

4 .Installation of the roller and carrier roller

Before the installation, we should check the rotary condition of the bearing and repair or change it in time if there is any problems in the rotating.

5 .The Unit Installation

The unit axis deviation is 0.02 mm; the radial error of coupling is 0.05 mm, the Clearance between the half couplings is 3 ~ 5 mm. the levelness and usage of the sizing block should also meet the specification requirements.

6 .The belt installation

The belt installation should be operated by the manufacture or the professional.

7. Oil the belt conveyor and make debugging

Ways to Maximize the Performance of Belt Conveyor

During application of belt conveyor, it is beneficial to reduce operating resistance by using high precision conveyor rollers and high performance belt. Revolving resistance of rollers and forward resistance of belt conveyor account for 50% main resistance in belt conveyor. If the belt conveyor length is more than 80m, main resistance will be influenced by device condition, friction coefficient related to real working condition, conveyor length, rotating quality in unit length of roller, belt quality, material property, etc.
Apart from above mentioned influential factor, we can refer to the following ways to maximize the performance of belt conveyor:
1.Reduce or adjust belt deviation;
2.Add lubricating oil to components of belt conveyor;
3.Clean up the sundries produced in transportation promptly;
4.Tension force of belt conveyor should be adjusted the best status;
5.Please add oil to conveyor pulley at fixed period to ensure smooth rotation;
6.It’s better to adopt vulcanized joint, though it costs too much money, it can keep a longer service life(especially suitable for fix belt conveyor).

How to prolong lifespan of belt conveyor

Quality of belt is the main reason to impact on belt conveyor lifespan, so it must purchase the belt with high quality. Meanwhile, it should make sure that sweeper is reliable to use so that there is no material on the return belt. Otherwise, materials adhered to return belt will be taken to the surface of drive pulley and bend pulley, then it will damage belt and reduce its lifespan.
There are some problems in the use of belt conveyors sometimes, to which require you to pay attention that you can greatly extend the service life of belt conveyor.
1. If there is the phenomenon of belt slipping on drive pulley, users should find the reasons and adjust it promptly.
2. Please always check the belt connectors, if there is local damage, please repair it or replace conveyors joints.
3. Please check rollers using conditions regularly. Adding proper lubricating grease into sealing ring when making maintenance. And replace inflexible rotating rollers immediately.
4. It must add good quality lubrication into all rotating parts of belt conveyor. Please add lubrication at fixed period in accordance with the requirements.
5. Please ensure that the cleaning device has good working conditions, and the damaged components should be replaced.
6. Please check tension level of belt conveyor regularly. If the belt is loose, please tension it promptly and observe whether the belt is off tracking, otherwise it should be adjusted timely.

Failure Analysis of Belt Conveyor Components

In the process of operation, failure of belt conveyor is inevitable, here PK Machinery will analyze the cause of belt conveyor failure.
1.Belt doesn’t rotate
After start-up of the belt conveyor motor, the belt of drive pulley idles and slips, belt can’t rotate, this failure is caused by insufficient belt tension, improper adjustment of tension device, overlong length, overloading start-up, coal piled in the tail part of belt conveyor.
2. Belt is easy to break
It is due to the large belt tension loose joint, poor quality of belt buckle, belt using for a long time, poor maintenance of belt, the solution is to tighten tension device, lower the tension ,change the new belt in time and strengthen the maintenance quality.
3. Reducer occurs abnormal sound.
The reason is due to the larger gap caused by serious wear of bearing and gear or screw is too loose, the solution is to replace the bearing, adjust the gap and repair or replace the whole reducer.
4.Reducer heats up too fast.
The reason is because of too much oil, poor heat dissipation performance, speed reducer is buried in coal pile, the solution is to adjust oil amount and remove the coal.

5.Reducer oil leakage.
The reason is due to the damage of sealing ring, the connecting surface of reducer is not uneven, the bolt is too loose, the solution is to replace the sealing ring, tighten the connecting surface and the bearing cap bolts.

 

6.Roller doesn’t rotate.
It is because of the damage of roller bearing, when coal powder enters into the roller sealing ring on both sides, it will be blocked and not rotate which makes the roller bend due to the large stress. The solution is replacement roller, reduce the height of discharging point and the landing point, or use the shock-proof roller at the landing point.
