Method of clearing abandoned firewall and firewall cut-off device

Abstract

The invention discloses a method of clearing an abandoned firewall and a firewall cut-off device. The method provided by the invention utilizes the firewall cut-off device to gradually cut off and clear the firewall section by section and comprises the following steps: firstly, the whole firewall cut-off device is hoisted to a to-be-cleared abandoned firewall in a roasting furnace through a hoisting device; secondly, the firewall cut-off device is driven to cut off a part of the abandoned firewall; thirdly, the cut-off abandoned firewall part is clamped by the firewall cut-off device and then is hoisted to an assigned position together with the firewall cut-off device through the hoisting device; and fourthly, the whole firewall cut-off device is again hoisted to the remnant abandoned firewall for another cut-off and clearing operation, thereby realizing the clearing for the whole abandoned firewall through repeated operation. The invention has the advantages of simple structure, convenience in operation, high operating efficiency and the like, and can effectively improve the work environment of operators and reduce labour intensity.

Description

technical field [0001] The invention relates to a method for removing waste flue walls and a flue wall cutting device, belonging to the technical field of electrolytic aluminum anode roasting furnace maintenance. Background technique [0002] Electrolytic aluminum anode roasting is a very important process, and the roaster is an indispensable equipment for anode roasting. After the roasting furnace has been used for a period of time, the furnace wall is easily deformed due to the constant air flow at high temperature and the uneven temperature change during the anode roasting process. Although the deformed furnace wall can continue to be used for a period of time after straightening and other repairs. However, the furnace wall, especially the flue wall, still often needs to be demolished and rebuilt. At present, when the flue wall is removed, it is often removed manually. Due to the limitation of the working furnace size of the roasting furnace itself, it is not easy to co...

AI Technical Summary

Problems solved by technology

At present, when the flue wall is removed, it is often removed manually. Due to the limitation of the working furnace size of the roasting furnace itself, it is not easy to construct, and in addition, a large amount of soot is left in the furnace wall when the anode is roasted, and Due to the long-term high temperature, the refractory bricks are bonded to each other

When dismantling, the working conditions of the workers are poor, the labor intensity is high, and the work efficiency is low

Therefore, the existing mode of removing the abandoned flue wall is still not ideal enough
