Aluminum electrolysis bath shell breaking air cylinder

Abstract

The invention belongs to the technical field of aluminum electrolysis bath shell breaking devices and particularly relates to an aluminum electrolysis bath shell breaking air cylinder. The air cylinder comprises a cylinder block, a piston and a piston rod, the piston is arranged in the cylinder block, an internal space of the cylinder block is divided into an upper space portion and a lower spaceportion, and the piston is linked to the piston rod; a micro air compressor is arranged on the cylinder block and comprises a housing, and a male rotor and a female rotor which are arranged in the housing; and a first connector and a second connector which communicate with the interior of the housing are formed in the housing, the first connector communicates with the upper space portion of the cylinder block, and the second connector communicates with the lower space portion of the cylinder block. The micro air compressor directly communicates with the air cylinder, the gas leakage phenomenoncan be reduced, meanwhile, it can be guaranteed that the gas supply pressure is constant, and normal operation of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of a sheller for an aluminum electrolytic cell, and in particular relates to a shelling cylinder for an aluminum electrolytic cell. Background technique [0002] In the electrolytic aluminum industry, the shelling cylinder is installed on the aluminum electrolysis electrolytic cell, which is an important production equipment of the electrolytic aluminum factory. [0003] The surface of the electrolytic cell is covered by a hard shell surface during electrolysis, and the shell surface of the electrolytic cell must be opened when feeding the electrolytic cell. At present, the shelling cylinder adopted by the electrolyzer is a shelling cylinder. Its reciprocating motion is driven by compressed air. The compressed air is generated by a special air compressor station, and is connected with the shelling cylinder of the electrolytic cell through the pipe network to make the shelling cylinder reciprocate.

AI Technical Summary

Problems solved by technology

[0004] The problem with the shelling cylinder is that the energy consumption is extremely high, the energy conversion rate of the air compressor station is only low, and the efficiency is lower after passing through the pipe network

[0005] In addition, the currently used shelling cylinder has the disadvantage that the shell surface cannot be opened due to the small shelling force. The shelling force is low during shelling, and it is particularly affected by the pressure of the pipe network, so the shell surface cannot be opened.
