Automatic dust cleaning system for dust collection air pipe

Abstract

The invention discloses an automatic dust cleaning system for a dust collection air pipe. The automatic dust cleaning system comprises the dust collection air pipe, a compressed air pipe and multiple air conveying assemblies, a plurality of air inlets are formed in the pipe wall of the dust collection air pipe, and a plurality of air outlets are formed in the pipe wall of the compressed air pipe; and the multiple air conveying assemblies are connected between the air outlets and the air inlets, and the air conveying assemblies are started at regular time to input high-pressure air in the compressed air pipe into the dust collection air pipe to clean dust in the dust collection air pipe. The purpose that the dust collection air pipe automatically blows dust in a timed and segmented mode is achieved, it is guaranteed that no dust is accumulated in the air pipe, pipeline ventilation is smooth, the dust collection effect is good, and the field operation environment is obviously improved; and meanwhile, the problem of incomplete product oxidation caused by unsmooth ventilation is solved, and the phenomenon of repeated roasting caused by incomplete material oxidation is avoided.

Description

technical field [0001] The invention belongs to the technical field of dust-cleaning devices, and in particular relates to an automatic dust-cleaning system for dust-collecting air ducts. Background technique [0002] When producing copper oxide powder by pyrometallurgy, a rotary tube type resistance furnace is generally used, and the rotary tube type resistance furnace adopts a forward draft method (inlet air from the feed end, and air out from the discharge end). During actual operation, the following problems exist. One is that the rotation of the rotary kiln causes some materials to fly, and some of the flying materials are brought out through the discharge end and enter the product without being completely oxidized, resulting in low product quality; The dust in the air duct is gradually deposited, resulting in the reduction of the ventilation area of ​​the air duct, which in turn causes the blockage of the air duct, resulting in insufficient oxygen supply in the rotary...

AI Technical Summary

Problems solved by technology

One is that the rotation of the rotary kiln causes some materials to fly, and some of the flying materials are brought out through the discharge end and enter the product without being completely oxidized, resulting in low product quality; The dust in the air duct is gradually deposited, resulting in the reduction of the ventilation area of ​​the air duct, which in turn causes the blockage of the air duct, resulting in insufficient oxygen supply in the rotary kiln, a decline in the dust collection effect, and a deterioration of the working environment, causing problems such as unqualified products and dust spill pollution; The third is that the materials of the rotary kiln are roasted at high temperature. The temperature of the dust collection pipe and the dust collection tank of the system is high, exceeding 80 degrees Celsius, which may easily cause the dust collection bag of the dust collector, the solenoid valve, etc. to malfunction or even be damaged.
