[0002] At present, the electric dust collector is used for the head dust removal of the sintering machine in the steel industry, and the electric dust collector is provided with a porcelain cylinder for hoisting and fixing the cathode line frame. The electric dust collector operates at about 160 DEG C. Since the temperature difference is large during operation and maintenance, the porcelain cylinder of the electric dust collector is easy to be damaged. When the porcelain cylinder is replaced each time, it is necessary to enter the inside of the electric dust collector, hoist the cathode frame and the cathode line bearing beam by using a hand-operated hoist, then loosen the cathode line hanging bolt, remove the porcelain cylinder pressure cover, and then take out the damaged porcelain cylinder, replace the new porcelain cylinder, restore the porcelain cylinder pressure cover and screw on the nut. When the replacement is carried out, the maintenance personnel need to enter the inside of the electric dust collector box. Since the temperature inside the electric dust collector is too high, the manhole needs to be opened to wait for cooling before entering. Each time of cooling needs a long time, so that each time of replacing the porcelain cylinder of the electric dust collector needs several hours, which greatly affects the production.
