Problems solved by technology

[0002] At present, in the process of using the chute to transport materials, when the material enters the chute through the feed port, it will induce the air in the surrounding environment to enter the chute. Due to the flow of air, the position of the feed port of the chute The pressure at the place is lower than the ambient pressure; while at the outlet of the feeding chute, because the kinetic energy of the air is converted into potential energy, the pressure at this location is greater than the ambient pressure, so that the material that comes out together with the material through the outlet of the feeding chute contains The dusty air will generate a lot of dust at the blanking point under the action of high pressure, which will pollute the environment and endanger the health of workers.
Therefore, when the existing feeding chute for conveying materials is in use, its use effect is still not ideal enough.

Embodiment Construction

[0011] Embodiments of the present invention: when performing dust prevention treatment on the existing feeding chute, the air pressure at the outlet of the feeding chute is greater than the pressure difference at the inlet of the feeding chute. The dust-containing air at the outlet of the material chute is pressed back into the material chute near the inlet through a connecting pipe connected to the inlet of the material chute, which can effectively reduce and prevent Dust generated at the outlet of the feeding chute.

[0012] During production, a connecting pipe 5 communicating with the inner cavity of the feeding chute 1 is connected on the existing feeding chute 1 near its feeding port 2, and the lower port of the connecting pipe 5 is arranged near the lower port. There are 3 outlets of the material chute 1; in order to more effectively collect the dusty air near the outlet 3, a trumpet-shaped reducer 4 can be connected to the lower port of the connecting pipe 5; in order t...

Abstract

The present invention discloses method and apparatus for preventing dust flying in the discharging elephant trunk. By means of the air pressure difference between the discharge port of the discharging elephant trunk with higher air pressure and its feeding port, the dusty air is made to return from the discharge port to the feeding port through one communicating pipe, reducing dust flying. The present invention has simple structure, good dust flying preventing effect and environment friendship.

Description

Technical field: [0001] The invention relates to a method and a device for preventing dust from a discharge chute, and belongs to the technical field of discharge chute for conveying materials.
