Aluminum electrolysis centralized control system and crust breaking control device thereof

Abstract

The invention discloses an aluminum electrolysis crust breaking control device which comprises a crust breaking machine, an unblockage-blockage condition sensing module and a treatment device; the unblockage-blockage condition sensing module used for acquiring the unblockage-blockage condition of unblockage and blockage of an unloading hole; and the treatment device is connected with the crust breaking machine and the unblockage-blockage condition sensing module and is used for controlling the crust breaking machine to execute a crust breaking movement before unloading and when the unblockage-blockage condition is blockage only. Seen from that the unblockage-blockage condition sensing module in the aluminum electrolysis crust breaking control device can acquire the unblockage-blockage condition of unblockage and blockage of the unloading hole, and the treatment device can control the crust breaking machine to execute the crust breaking movement before unloading and when the unblockage-blockage condition is blockage only, so that unnecessary crust breaking movement is avoided, use and loss of relative software and hardware are reduced, and the electric quantity is saved at the sametime. The invention also discloses an aluminum electrolysis centralized control system. The aluminum electrolysis centralized control system has the beneficial effects same as the crust breaking control device.

Description

technical field [0001] The invention relates to the field of aluminum electrolysis, in particular to a shelling control device for aluminum electrolysis, and also relates to a centralized control system for aluminum electrolysis. Background technique [0002] Electrolytic aluminum is a method commonly used in industrial aluminum production. In one step of the electrolytic aluminum process, alumina needs to be put into the electrolyte through the feeding hole, but some reactions will occur around the feeding hole. It will be blocked naturally. In order to solve this problem, in the prior art, before each blanking, it is necessary to control the sheller to perform a shelling action at the blanking hole so that the blanking hole is unimpeded. However, in the prior art, the shelling machine can only be fixedly controlled to perform a shelling action before each feeding, but in some cases, the feeding hole itself is not blocked, which is not necessary in this case. If it is nece...

Problems solved by technology

However, in the prior art, the shelling machine can only be fixedly controlled to perform a shelling action before each feeding, but in some cases, the feeding hole itself is not blocked, which is not necessary in this case. If it is necessary to perform the shelling action, the redundant shelling action will cause redundant loss of software and hardware and waste of electric energy
