Abstract

The invention discloses a mining dust removal fan. The mining dust removal fan comprises a suction section and an enlarged section which constitute a venturi structure, and a drainage chamber is further arranged between the suction section and the enlarged section; the drainage chamber comprises an enlarged component I and an enlarged assembly II; the mining dust removal fan further comprises a valve block and a suction valve mounted on the valve block, a nozzle is disposed at the central position of the suction section and oriented from the suction section toward the drainage chamber; and a material inlet is formed in the top of an additive material tank for feeding. The mining dust removal fan has the advantages that a vacuum environment is formed by the high-pressure gas of the Coanda effect, and dust is sucked in and the high-pressure mixed water is used for cleaning the dust. Meanwhile, the mining dust removal fan has no electrical elements, the management difficulty and risk factor of the dust removal fan are reduced, and the work in a high gas environment is met.

Description

technical field [0001] The invention relates to the field of mine equipment, in particular to a mine dust removal fan. Background technique [0002] Mine dust is one of the main disasters in coal mines. Workers who work in dense dust environment for a long time are prone to suffer from pneumoconiosis, and the accumulation of dust can easily cause explosion accidents, which pose a serious threat to mine safety production. [0003] Dust collectors are the main dust reduction equipment for fully mechanized excavation, but dry dust collectors cannot remove toxic and harmful components in the gas, and are generally large in size, making installation and movement inconvenient; wet dust collectors consume a lot of water, and power devices generally use electric components. The noise is loud during work, and there are electrical safety hazards for high-gas mines. In order to solve the above-mentioned problems existing in the existing dust removal fan, the application proposes a new...
