Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to concrete production and processing, and specifically relates to a bag-type dust removal device for concrete production. Background Technique

[0002] A large amount of dust is generated during the concrete production process. These dusts not only affect the environment and the health of operators, but may also cause safety accidents. Therefore, it is very necessary to use an efficient bag-type dust removal device to collect and process these dusts. The bag-type dust collector captures dust by means of the wind flowing at high speed under negative pressure in cooperation with a gas collection hood. The dust settles in the ash hopper under the action of gravity, and fine dust particles are deposited on the filter bag through the combined effects of inertial collision, sieving, etc. on the surface of the filter bag. The purified gas is discharged through the exhaust pipe. The bag-type dust collector is widely used in eliminating dust pollution, improving the environment, recycling materials, etc. The application of the bag-type dust removal device in concrete production is not only efficient, but also of great significance for improving the production environment and protecting the health of employees.

[0003] In the utility model patent named "A Bag-Type Dust Removal Device for Commercial Concrete" (application number 202321311626.5), it is proposed that "The utility model discloses a bag-type dust removal device for commercial concrete, including a housing, a fixing frame is fixedly connected to the surface of the housing, a cover plate is movably connected to the top of the housing through a pin, an air inlet pipe is fixedly connected to the top of the cover plate, the bottom of the air inlet pipe penetrates to the inner cavity of the housing and is communicated with a connecting hose, and the bottom of the connecting hose is communicated with a dust collection bag. Through the combined use of the housing, the fixing frame, the cover plate, the air inlet pipe, the connecting hose, the dust collection bag, the mounting frame, the positioning plate, the limiting mechanism, the positioning hole, the sliding rod, the sliding sleeve, the first spring, the clamping plate, the positioning mechanism, the positioning frame, the air purification plate, the air outlet pipe, the fixing ring, the limiting ring, the slot and the insertion block, the problem that the existing bag-type dust removal device is not easy to disassemble after installation, resulting in a large amount of working time required for the staff to replace it, thus reducing the working efficiency of the bag-type dust removal device is solved." However, this utility model patent has the following problems:

[0004] 1. In this application, it is not considered that the gas passing through the bag-type dust removal component still contains some impurities, and only purified by the air purification plate.
