Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain storage conveyor line equipment, in particular to a dust removal and recycling device for a tensioning room conveyor line. Background Art
[0002] Grain is generally transported in and out of the warehouse by conveyor lines. The grain conveyor line includes the conveyor line body, conveyor line cover, bracket, etc. In the process of conveying grain and cereals by belt conveyor line, dust will be generated, which will cause pollution to the workshop. Dust will also adhere to the ground, platform and the top of the conveyor line. In the long run, the surrounding environment is relatively polluted, and manual cleaning is inconvenient, which increases the workload of personnel on the production line. During the conveying process of the belt conveyor line, a blower is required to supply air. When air with a certain pressure enters the air chamber, it is sprayed onto the belt through the small holes on the slot plate, and an air cushion is formed between the belt and the slot plate to lift the belt. Then the air overflows from both sides of the disc slot and enters the atmosphere. The belt runs under the action of the drive motor to achieve the purpose of conveying materials. At this time, there will be air leakage in the gap of the conveyor line cover, and dust will escape from the air leakage point, polluting the surrounding working environment. For this reason, a tensioning room conveyor line dust removal and recycling device is proposed. Utility Model Content
