Description

Electrode sealing cover Technical Field The utility model relates to the field of electrode sealing covers, in particular to an electrode sealing cover. Background The sedimentation and depletion electric furnace in the smelting workshop is a furnace kiln matched with a smelting system, the sedimentation electric furnace mainly treats high-temperature melt produced by smelting, and the depletion electric furnace mainly treats high-temperature slag produced by a converter. In the normal production operation process, the electrode column is inserted into the electric furnace, and the electrode column is required to operate up and down according to the actual conditions such as consumption conditions, insertion depth, voltage level adjustment and the like, and meanwhile, in the operation process, the electrode column is prevented from contacting and rubbing with an electrode hole at the top of the electric furnace. In the current production process, because the gap exists between the electrode column and the electrode hole, air leakage is large, and in the negative pressure regulation and control process, part of smoke is dissipated from the gap, so that the environment pollution of an operation site is caused, and the body health of operators is influenced. Disclosure of utility model In order to solve the technical problems, the application provides an electrode sealing cover. The application provides an electrode sealing cover, which adopts the following technical scheme: The utility model provides an electrode seal cover, includes the cover body, the top of electric stove is located to the cover body cover, the bottom surface of the cover body is provided with the round and prevents firebrick, the top surface butt of firebrick and electric stove, still be provided with round brass sealing ring on the inner wall of the cover body, the inner peripheral wall and the outer peripheral wall butt of electrode post of brass sealing ring. Preferably, be provided with the air inlet cover on the peripheral wall of the cover body, the cover body is provided with the ventilation clearance with the position department that the air inlet cover is connected, the lateral wall cavity of the cover body sets up, the ventilation clearance sets up on the lateral wall body of the cover body, the inside wall body of the cover body is provided with the air inlet clearance, air inlet clearance and ventilation clearance intercommunication, ventilation clearance and air inlet cover intercommunication, be provided with the tuber pipe on the top surface of air inlet cover, set up the wind gap with the tuber pipe intercommunication on the top surface of air inlet cover, the top of tuber pipe is the external air supply, the air supply passes through the air pump towards the tuber pipe pump air supply. Preferably, the air inlet cover is arranged at least two along the circumferential direction of the cover body, and the top surface of each air inlet cover corresponds to one air pipe. Preferably, a guide wheel is arranged on the top surface of the cover body, the guide wheel is rotationally connected with the top surface of the cover body through a base, and the outer peripheral wall of the guide wheel is abutted with the outer peripheral wall of the electrode column.
