Problems solved by technology
[0004] However, there are still some defects in the above methods. The use of fan forced cooling requires a large investment, and the cooling parts are not concentrated, resulting in increased energy consumption; and the temporary compressed air cooling method is poor in timeliness, and the air pipe is placed on the cover between the slots to hinder Normal operation, and it is not safe for operators to hold heavy blower steel pipes between the column busbars under high temperature and strong magnetic field environment; the method of adding cooling fins on the side wall of the tank shell cannot solve the forced cooling of the local overheating of the side wall of the tank shell question

Embodiment Construction
[0013] Embodiments of the present invention: the local forced cooling method of the aluminum electrolytic cell shell side wall of the present invention is for example figure 1 shown. The method of the present invention is: install an anti-magnetized steel air duct 1 that can move in parallel along the side wall 7 of the tank shell between the ventilation plate 9 between the tanks and the cradle bracket 8 of the tank shell, and its installation position is arranged reasonably and has concealment , does not affect the normal operation of any equipment, beautiful and simple. One end of the anti-magnetized steel air duct is connected to the joint of the air source through the soft air duct 4, between two adjacent air duct fixing rings 2 in each section (the distance can be selected to facilitate movement between 3 or more cradle frames) The anti-magnetized steel air duct 1 is provided with one or more blowing heads 5, and each group can be equipped with one or more blowing heads....

The invention discloses a local forced cooling method and device for an aluminum electrolytic cell shell. The method is to install an anti-magnetized steel air duct that can move in parallel along the side wall of the tank shell between the ventilation plate between the slots and the cradle bracket of the slot shell, and one end of the anti-magnetized steel air duct is connected to the joint of the air source through a soft air duct Above, there is a blower head on the anti-magnetized steel air pipe, and there is a movable pull ring on the anti-magnetized steel air pipe. Pulling the movable pull ring can move the anti-magnetized steel air pipe so that the blower is aligned with the side wall of the tank shell that needs local forced cooling Concentrated air cooling. The invention can concentrate wind force to locally force ventilation and cool the side wall of the tank shell under the condition of low energy consumption. And it has the characteristics of simple structure, easy manufacture, safety and convenience, and convenient movement.
Description
technical field [0001] The invention relates to a local forced cooling method and device for the side wall of an aluminum electrolytic cell shell, and belongs to the technical field of air cooling of the side wall of an aluminum electrolytic cell shell. Background technique [0002] With the increase of the current capacity of the modern aluminum electrolytic cell, the cathode heat balance state of the electrolytic cell and the prolongation of the cell life have been widely concerned. As we all know, during the firing start-up and production operation of an aluminum electrolytic cell, the surface of the side of the tank shell is reddened, the window of the cathode steel rod is aluminized, and even the side wall of the tank shell is burned through due to the current deviation in the tank or the melting of the side of the furnace. This will seriously affect the stable operation of the electrolytic cell and shorten the service life of the cell lining, affect the production tech...
