Aluminium plant electrolytic carbon residual anode surface pellet injecting and sandblast cleaning system and method

Abstract

The present invention is shot and sand blasting system and method for cleaning residual carbon electrode from electrolyzing aluminum. The cleaning system includes one shot and sand blasting chamber as sealed space for shot and sand blasting operation for processing the surface of residual carbon electrode from electrolyzing aluminum to eliminate impurity and recover carbon; one piece of shot and sand blasting equipment including one automatic continuous shot and sand blasting device and one automatic shot and sand blasting mechanism with spraying guns; and one shot and sand recovering device. The present invention is favorable to recovering carbon for reuse.

Description

technical field [0001] The invention relates to an electrolytic impurity cleaning process and treatment system in the carbon plant (workshop) of an aluminum company or an aluminum plant in the recovery process of carbon residues after electrolysis, and the carbon plant is cleaned by automatic sandblasting (shot) The electrolytic impurities on the outer surface of the electrolyzed carbon residue are beneficial to the recovery of the reusable carbon after electrolysis. Background technique [0002] The main component of the carbon anode is a carbon block, and the outer surface (mainly the outer surface of the anode) adheres to the electrolyte that is harmful to recovery and needs to be cleaned. The existing treatment methods for the carbon residues of the aluminum company or the carbon factory of the aluminum factory are as follows: [0003] 1. With the manual cleaning equipment, the manufacturer generally adopts a residual pole workpiece to pass through the platform. When th...

[0004] 2. Shot blasting equipment cleaning device, which is usually composed of a shot blasting room, a shot head, a hinged shot conveyor, a bucket-type shot elevator, a shot sorter, and a dust collector. The working principle of shot blasting is: It is mainly based on the principle of centrifugal force, and the adjustment of the position of the blasting head is inconvenient. The conveying and lifting of the shot is mainly realized by the mechanical reaming dragon shot conveyor and bucket-type shot elevator, which has a high failure rate and a large amount of maintenance. The airtightness of the room body is poor during work, a large amount of shot material splashes outside the room, and personnel outside the room cannot get close to the equipment. The overall noise effect of the device is not good

Therefore, for the above problems, the user is often forced to stop using the device shortly after it is put into use.
