Conduit device with anti-blocking and foreign matter discharging functions for powder processing

Abstract

The invention discloses a conduit device with anti-blocking and foreign matter discharging functions for powder processing. The conduit device comprises an air inlet pipe, a middle pipe, an air outletpipe, a collecting hopper, a check valve and a discharge pipe; the air inlet pipe is obliquely arranged, and a pipe opening in the upper end of the air inlet pipe is used for receiving dusty gas; themiddle pipe is horizontally arranged, and a pipe opening in one end of the middle pipe hermetically communicates with a pipe opening in the lower end of the air inlet pipe; the air outlet pipe is vertically arranged, a pipe opening in the lower end of the air outlet pipe hermetically communicates with a pipe opening in the other end of the middle pipe, and a pipe opening in the upper end of the air outlet pipe hermetically communicates with a roasting furnace; the collecting hopper is located below the middle pipe and the air outlet pipe and hermetically communicates with the middle pipe andthe air outlet pipe, and the conical surface inclination angle of the collecting hopper is not smaller than 45 degrees; the check valve is located below the collecting hopper and is vertically arranged, and a valve port in the upper end of the check valve hermetically communicates with an outlet in the bottom of the collecting hopper; and the discharge pipe is located below the check valve and isvertically arranged, a pipe opening in the upper end of the discharge pipe hermetically communicates with a valve opening in the lower end of the check valve, and a pipe opening in the lower end of the discharge pipe is connected into a collecting box.

Description

technical field [0001] The invention belongs to the technical field of powder processing, in particular to a catheter device for powder processing with functions of preventing blockage and removing foreign matter. Background technique [0002] During the roasting preparation process of magnesium oxide powder, blocky foreign objects sometimes fall from the roasting furnace. If these foreign objects are not discharged from the pipeline in time, the cross-sectional area of ​​the pipeline will become smaller and smaller, which will increase the resistance of the pipeline and cause The reduction of the output of magnesium oxide powder, and in serious cases even completely block the pipeline. At this time, the production can only be stopped and the pipeline is dredged, which will eventually lead to the stability and efficiency of the roasting preparation of magnesium oxide powder. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present in...

[0002] During the roasting preparation process of magnesium oxide powder, blocky foreign objects sometimes fall from the roasting furnace. If these foreign objects are not discharged from the pipeline in time, the cross-sectional area of ​​the pipeline will become smaller and smaller, which will increase the resistance of the pipeline and cause The production of magnesium oxide powder decreases, and in severe cases, the pipeline will be completely blocked. At this time, the production can only be stopped and the pipeline will be dredged, which will eventually lead to the stability and efficiency of the roasting preparation of magnesium oxide powder.
