Belt conveyor drop point combined dust suppression and dust removal device

Abstract

A dust suppression and removal combined device for drop points of belt conveyors. The dust suppression and removal combined device for the drop points of the belt conveyors mainly solves technical problems of complex structure, ineffectiveness and the like of an existing dust suppression and removal device. The main points of the technical scheme of the dust suppression and removal combined device for the drop points of the belt conveyors include that a blanking tube of the belt conveyor and a bag filter are combined, a box (402) is separated into two portions through a separation plate. Two or more blocking plate supports (404) sloping downwards at a certain angle are arranged on the inner wall of the blanking tube in a left-right staggered and stepped mode and provided with abrasion-resistant lining plates (405); a dust removal chamber is provided with a filter bag (409), a filter bag frame (410) and a dust cleaning device (408). The dust suppression and removal combined device is mounted on the blanking place of the two belt conveyors with a certain drop. The dust rose during blanking can be reduced through deflection baffles, the rose dust in an upper closing cover, a lower closing cover and the blanking tube is sucked and collected for purification through the negative pressure generated by a draught fan dust of the dust removal device. The dust suppression and removal combined device for the drop points of the belt conveyors is mainly used for dust suppression and removal in the process of feed conveying at the drop points of the belt conveyors.

Description

technical field [0001] The invention relates to a combined dust suppression and dust removal device for the drop point of a belt conveyor. Background technique [0002] At present, belt conveyors with large specifications and long-distance transportation often have multiple transfer stations during the transportation process, and there is a certain drop between the front and rear belt conveyors. When the material is unloaded from a high place to a low place, a certain amount of dust will always be generated near the belt conveyor. As the height difference of the drop point increases, the amount of dust will increase. The main reasons for the generation of dust are as follows: [0003] 1. During the transportation of the material, the inertia generated when it is separated from the belt causes the dust to separate from the material and cause flying; [0004] 2. The operation of the belt and mechanical device of the conveyor, and the air flow carried by it, cause the dust in...

AI Technical Summary

Problems solved by technology

[0003] 1. During the transportation of the material, the inertia generated when it is separated from the belt causes the dust to separate from the material and cause flying;

[0004] 2. The operation of the belt and mechanical device of the conveyor, and the air flow carried by it, cause the dust in the material to fly

While cleaning the dust, the filter bag will also lose its filtering function instantaneously, which is not conducive to the long-term and stable operation of the system

[0014] 4. When the dust is discharged from a high place to a low place, the potential energy generated by the drop of the material cannot be eliminated, and the kinetic energy generated by falling on the receiving belt conveyor always exists the possibility of causing the dust to fly
