Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a coal powder cleaning device for cleaning coal conveyor belts. Background Technology

[0002] Thermal power plants use conveyor belts to transport pulverized coal. Because the coal contains pulverized coal, it is easy for the pulverized coal to scatter during transportation, generating a large amount of dust. Chinese utility model patent, authorized announcement number "CN216402877U", discloses a pulverized coal cleaning device for conveyor belts. In this utility model, by setting up a pulverized coal cleaning device for conveyor belts, the upper pulverized coal cleaning box and the lower pulverized coal cleaning box can effectively clean the pulverized coal on both sides of the conveyor belt, preventing the pulverized coal from spreading in the air and preventing it from falling to the ground and causing pollution.

[0003] While the above-mentioned technical solution can effectively clean the coal dust on both sides of the conveyor belt when used in conjunction with the upper and lower coal dust cleaning boxes, the dust collection structure is located above the conveyor belt, making the coal dust on the conveyor belt easily dispersed by the suction force of the suction fan. Relying solely on the scraper to clean the conveyor belt causes some large coal dust particles to fall off, but some smaller dust particles will disperse inside the cleaning box and are difficult to collect and discharge in a timely manner. Therefore, we propose a coal dust cleaning device for cleaning coal conveyor belts. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a coal dust cleaning device for cleaning coal conveyor belts. This device can effectively clean the coal dust on both sides of the conveyor belt when the upper and lower coal dust cleaning boxes are used in conjunction. However, because the dust suction structure is located above the conveyor belt, the coal dust on the conveyor belt is easily scattered by the suction force of the suction fan. Relying solely on the scraper to clean the conveyor belt causes some large coal dust particles to fall, but some smaller dust particles will float inside the cleaning box and are difficult to collect and discharge in a timely manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal dust cleaning device for cleaning coal conveyor belts, comprising:

[0006] The belt conveyor and the fixed base are fixedly connected to the top of the fixed base;
