Combined technical solution of roller and belt conveyor

The belt conveyor is widely used in the transportation of raw coal in the coal industry. It has the characteristics of stable operation, large carrying capacity, low maintenance cost after operation, easy to realize automation and centralized control, etc. It is especially widely used in the coal industry.

Rollers play the role of driving and reversing in the belt loading conveyor, and are an important part of the conveyor. The drum can be divided into external drive and internal drive. Its shape can be divided into drum drum, blade drum and grooved rubber surface drum.

In low temperature and severe cold areas, due to the influence of climate and transport materials, the surface of the roller will freeze during the operation of the belt conveyor during directional transportation, which will reduce the friction of the belt. Small, the tightness of each part is inconsistent. It is the most common belt misalignment fault. So deviations must be corrected and belts calibrated frequently every shift.

1.Technical solution

Through the problem analysis, the method of spraying antifreeze at fixed points and timing of the roller can effectively solve the problem of roller freezing. Reduce equipment failure rate and improve equipment production efficiency.

2. Device production

Use φ15 galvanized steel pipe to make pipelines, and make branch pipelines at the diverting rollers of each layer. The pipelines are installed in parallel and 400mm above the reversing drum. Each parallel pipeline is equipped with 4 atomizing nozzles. Each branch is equipped with multi-point control of solenoid valves. It relies on a self-priming pump to boost pressure to form an antifreeze spray device.

3. Application effect

After the belt conveyor roller spraying device is used, spray antifreeze on the surface of the roller to slow down the roller from freezing phenomenon and reduce the occurrence of equipment failures. The frequency of belt misalignment failures has been significantly reduced, from 1 to 2 times per shift to 1 to 2 times per week, achieving good application results and ensuring effective production time.

The utility model is suitable for low temperature and severe cold regions, and can be popularized and applied in enterprises that use belt conveyors in similar climatic environments.
