Dust recovery system of electrolyte manual cleaning workshop section

Abstract

Provided is a dust recovery system of an electrolyte manual cleaning workshop section. The dust recovery system of the electrolyte manual cleaning workshop section comprises feeding hoppers, a bag filler, a centrifugal fan, dust removal air pipes and exhaust hoods, wherein the independent feeding hoppers are assembled below feeding grids of stations of the electrolyte manual cleaning workshop section respectively, openings are formed in the two opposite sides of the upper portion of each feeding hopper, each opening is communicated with the corresponding exhaust hood, the exhaust hoods arranged on the same sides of the feeding hoppers are communicated with the dust removal air pipes respectively, the two dust removal air pipes are communicated with an air inlet of the bag filler at the same time, and an air outlet of the bag filler is communicated with an inlet of the centrifugal fan. According to the dust recovery system of the electrolyte manual cleaning workshop section, the dust removal technology is applied to working places where closed exhaust hoods cannot be arranged, effective control over dust of a manual operation place is achieved, the working environment required by an existing process system is ensured, the dual-purpose effect is achieved, and the dust recovery system of the electrolyte manual cleaning workshop section has good application prospect.

Description

technical field [0001] The invention belongs to the electrolyte dust treatment technology of an aluminum electrolysis plant, and in particular relates to a dust recovery system in an electrolyte manual cleaning section. Background technique [0002] The carbon anode is used as the anode end of the aluminum electrolysis process, where it interacts with CO 2 During the reaction process, the anode blocks are consumed to form residual electrodes. In order to ensure the normal production process of electrolytic aluminum, they need to be replaced regularly. [0003] The anode assembly workshop is the production workshop of electrolytic aluminum anodes. While assembling new carbon anode blocks, it also needs to process the residual anode blocks returned from the electrolysis workshop; most of the electrolyte cleaning work is done manually. of. In the process of cleaning and blanking, a large amount of dust will be produced. If the dust cannot be well controlled, it will inevitabl...

AI Technical Summary

Problems solved by technology

In the process of cleaning and blanking, a large amount of dust will be produced. If the dust cannot be well controlled, it will inevitably bring harm to the physical and mental health of the operator, and will also cause serious pollution to the environment of the workshop; Restricted by the conditions, the dust collection cover cannot be installed on the ground of this process, and there is no good condition for the dust removal system to be installed.

In the previous design of the electrolyte manual cleaning section, the practice of setting a slit-type dust collection cover under the blanking grid was mostly adopted. However, since multiple stations work at the same time during the production process, the total length can reach more than ten meters. It is difficult to achieve the ideal dust collection effect with the slit dust collection cover
