Description

Technical Field

[0001] The invention belongs to the technical field of dust removal equipment, and in particular relates to a vibration type dust removal device. Background Art

[0002] During the production process of concrete mixing plants (stations), since cement warehouses produce large dust particles during cement tanker loading and normal use, and cement tankers often require a large pumping pressure when loading materials into cement warehouses, cement in the warehouse will produce a large amount of dust-containing gas after being impacted by pressure. If the gas containing cement dust is directly discharged into the atmosphere outside the cement warehouse, it will not only cause a large amount of cement waste, but also cause serious air pollution. Usually, a dust removal and filtering device is set on the top of the cement silo of the mixing plant to filter and discharge the gas containing cement particles; however, traditional cement silo top dust collectors are generally bag dust collectors, pulse dust collectors, etc., because there is no fluid deceleration device when the dust-containing gas enters the filter bag (filter cartridge), the traditional dust collector wears faster under the action of large external pressure, has a short service life, and the dust-containing gas flow rate is fast, resulting in poor dust removal effect; the traditional dust collector box filter bag (filter cartridge) dust removal generally chooses external high-pressure air flow to flush the dust, and the dust removal effect is poor when the dust amount of the filter bag (filter cartridge) is large.
