Belt fall point dust removal system

Abstract

The invention discloses a belt fall point dust removal system which is used by a bulk material in the belt transportation process. The belt fall point dust removal system comprises a handpiece sealing hood (1), a material runner (2) and a sealing hood (3) on the lower part of an engine body, wherein the discharge hole of the handpiece sealing hood (1) is connected with the feed port of the material runner (2); the discharge hole of the material runner (2) is connected with the feed port of the sealing hood (3) on the lower part of an engine body; the top of the sealing hood (3) on the lower part of an engine body is provided with a first dust remover (4); the top of the handpiece sealing hood (1) is provided with a second dust remover (5); a dust gas backflow channel (7) is fixedly arranged between the sealing hood (3) on the lower part of an engine body and the material runner (2); and the port of the dust gas backflow channel (7) is respectively communicated with the material runner (2) and the cavity of the sealing hood (3) on the lower part of an engine body. The invention saves the existing water resource, has ideal dust removal effect, is convenient to install and maintain and does not generate secondary pollution.

Description

technical field [0001] The invention belongs to the field of environmental protection dust removal equipment, and in particular relates to a belt drop point dust elimination system used in the process of belt transportation of bulk materials. Background technique [0002] In order to solve the dust generated at the drop point during the transportation of bulk materials by the belt conveyor, two dust removal methods are generally used, namely wet dust removal or dry dust removal. The wet dust removal method will limit the application field of materials in a specific environment. At the same time, this kind of dust removal equipment is a serious waste of water resources, and the dust removal effect is not ideal, which often causes unnecessary secondary pollution. The dry dust removal method mainly uses a vacuum hood to capture the dust emitted by the dust source so as not to spread it into the working environment. However, due to the thermal pressure caused by the different a...

Problems solved by technology

However, due to the heat pressure caused by the different air temperature inside and outside the cover, positive pressure will be formed in some places inside the cover. At this time, a dusty airflow will escape from the orifice or the gap that is not tight, thereby polluting the surrounding environment.

In addition, in terms of structural design, due to uneven wind speed at the mouth of the dust collection hood and improper matching of the mouth size, the dust collection effect is often not ideal.
