Problems solved by technology

[0002] At present, the inner wall of the unloading chute used to transport materials is generally a smooth inner wall. When the unloading chute with this smooth inner wall is used to transport materials, especially when the unloading chute with a large inclination angle transports materials During the process, when the material to be conveyed (especially the bulk material) goes down to the belt conveyor or other material drop point through the inclined discharge chute, the falling speed of the material is very fast due to the large inclination angle of the discharge chute. Fast, the impact on the blanking point is greater, which will generate more dust, which will pollute the environment and endanger the health of workers

Embodiment Construction

[0011] Embodiments of the present invention: adopt the method of setting damping buffer plate in the discharge chute, use the resistance produced by the damping buffer plate to the material moving in the discharge chute to reduce the descending speed of the material in the discharge chute and the material passing through the discharge chute The discharge speed at the outlet of the chute can reduce the impact force of the material on the discharge point, thereby achieving the purpose of reducing dust.

[0012] During implementation, preferably at least be installed on the lower wall plate in the pipe body (1) of the discharge chute that is provided with feed inlet (2) and discharge outlet (3) and the side wall plate on both sides 1 layer of damping buffer plate (4) arranged according to U-shaped opening; but under normal circumstances, it is better to install 5 layers of damping buffer plate (4) arranged according to U-shaped opening on the lower wall plate and the side wall pla...

Abstract

The invention discloses a method for reducing dust of feeding tube and relative device. It arranges damp baffle plate inside the feeding tube, to generate resistance to reduce the material falling speed inside the feeding tube and the discharging speed when through the outlet of feeding tube, to reduce the impact force to reduce the dust. The invention can reduce fly dust, with simple structure, easy operation and better anti-dust effect.

Description

Technical field: [0001] The present invention relates to a method and device for reducing the dust in the discharge chute for transporting materials, in particular to a method and device capable of preventing the conveyed bulk material from falling to the discharge point through the outlet of the discharge chute due to The invention relates to a method and a device for reducing the dust of a feeding chute that generates a large amount of dust due to a large impact force, and belongs to the technical field of a feeding chute for conveying materials. Background technique: [0002] At present, the inner wall of the feeding chute used for conveying materials is generally a smooth inner wall. When the feeding chute with this smooth inner wall is used to convey materials, especially when the feeding chute with a large inclination angle is used to convey materials During the process, when the material to be conveyed (especially the bulk material) goes down to the belt conveyor or o...
