Multifunctional four-link sheller

Abstract

The invention relates to a multifunctional four-connection-rod crust breaker. The multifunctional four-connection-rod crust breaker comprises a rack, a hoisting oil cylinder fixed above the rack and upper and lower oscillating bars with two ends connected with the rack and a machine head seat respectively; the upper oscillating bar is composed of a retractable oil cylinder and a retractable rod; the multifunctional four-connection-rod crust breaker is characterized by further comprising a magnetic lock energy-storing air cylinder capable of driving a machine head to carry out strong single-beating work; the magnetic lock energy-storing air cylinder is connected with a piston rod of the hoisting oil cylinder by a slide frame; a piston rod of the magnetic lock energy-storing air cylinder is connected with the lower oscillating bar. The multifunctional four-connection-rod crust breaker is characterized in that strong single beating and continuous impacting functions exist; a crust breaking machine head is retractable and has an adjustable angle; the functions are complete and the crust breaking efficiency is high; the time and the labor are saved and the service life of the crust breaker is long.

Description

technical field [0001] The invention relates to shelling equipment for crusting of aluminum electrolytic tanks, in particular to a four-link shelling machine with multiple functions. Background technique [0002] In the aluminum electrolytic production process, there are crusts at different positions on the furnace of the electrolytic cell. According to production requirements, shelling operations need to be performed at the edge of the electrolytic cell and the seam in the cell. The existing four-link sheller uses a hydraulic cylinder to drive the lower swing rod of the four-bar linkage mechanism to adjust the angle of the sheller head, so that the end of the sheller head rests on the shell surface, and adjusts the angle of the sheller head through the telescopic upper swing bar. The posture of the machine head enables it to complete the shelling operation in different positions of the electrolytic cell. This four-link shelling machine uses the pneumatic head to impact the...

AI Technical Summary

Problems solved by technology

This four-link shelling machine uses the pneumatic head to impact the crust to make it broken. Due to the large thickness and strength of the crust, the impact force of the machine head is small, so it needs to be continuously impacted, and the long-term continuous operation will affect the use of the machine head. Life, easy to cause damage to the machine head, low shelling efficiency, time-consuming and labor-intensive, waste of energy

The piston rod of the hydraulic cylinder is exposed, which is vulnerable to splashing and burning of high-temperature liquid electrolyte, which reduces the service life of the hydraulic cylinder
