Dust collection device and environment-friendly discharge device

Abstract

The invention discloses a dust collection device and an environment-friendly discharge device. The dust collection device comprises a dust collection inner cover and a dust collection outer cover. Theouter side of an outlet of a receiver bin is sleeved with the dust collection inner cover, and thus a second passage with the upper end closed and the lower end open is formed. The outer side of thedust collection inner cover is sleeved with the dust collection outer cover, and the dust collection outer cover and the dust collection inner cover form a first passage with the upper end closed andthe lower end open. The side face of the dust collection outer cover is provided with a dust collection port communicating with the first passage. The first passage sucks raising dust at an opening ofthe lower end of the second passage, and the raising dust is discharged through the dust collection port. A double-layer dust collection cover body is arranged in a dust collection area to form an airtight air curtain on the periphery of a discharge point. Secondary raising dust moves to the dust collection inner cover and then is blocked down. Small dust particles flow over under the action of material flow air pressure and are sucked away by an extraction discharge port at the gap of the dust collection inner and outer covers. Accordingly, the dust collection device can absorb and suppressraising dust ingeniously.

Description

technical field [0001] This application relates to the field of material distribution, specifically a dust removal device and an environment-friendly discharge device. Background technique [0002] In recent years, air pollution has become the top priority of national environmental protection management, and bulk materials are still one of the main sources of solid particle pollution in the atmosphere; as the main raw material transportation method for bulk materials such as barge, reverse, and short-distance transportation, automobile transportation is widely used It is used in the material transfer process of metallurgy, cement, coal, power plants and other industries; however, due to the frequent replacement of vehicles during the shipment of bulk materials, the relative positional relationship is uncertain, and it is impossible to achieve full sealing through the traditional dust-removing sealing cover, and After the material hits the carrier, it will cause secondary dus...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this application is to provide a dust removal device and an environmentally friendly discharge device for the defects of the existing technology. By setting a relatively closed space and matching multiple diffusion chambers, the large particle materials can be effectively settled and the dust can pass through the negative Absorption under pressure to achieve the effect of solving the waste of raw materials and dust pollution
