Explosion-proof cover mechanism on smelting furnace

Abstract

The invention discloses an explosion-proof cover mechanism on a smelting furnace. The explosion-proof cover mechanism comprises a furnace body; a pressure relief hole is formed in the furnace body; anexplosion-proof pipe is formed on the outer wall of the furnace body; an explosion-proof cover is inserted into the explosion-proof pipe; a guide column is formed on the explosion-proof cover; a positioning plate is inserted into the explosion-proof pipe; a guide hole is formed in the center of the positioning plate; the guide column is inserted into the guide hole; the guide column is sleeved with a first compression spring in an inserted manner; a pressure relief groove is formed in the side wall of the explosion-proof pipe; a limiting hole is formed in the side wall of the guide column; anaccommodating groove is formed in the inner wall of the guide hole; a telescopic rod is inserted into the accommodating groove; the telescopic rod consists of several joint pipes; the adjacent jointpipes are inserted together; an iron block is fixed to the leftmost joint pipe of the telescopic rod; a first electromagnet is fixed to the inner wall of the accommodating groove; the telescopic rod is sleeved with a second compression spring in an inserted manner; the two ends of the second compression spring abut against the leftmost joint pipe of the telescopic rod and a support correspondingly; and a second electromagnet is fixed in the limiting hole. According to the invention, the explosion-proof cover after explosion-proof pressure relief can be automatically closed.

Description

Technical field: [0001] The invention relates to the technical field of smelting furnaces, in particular to an explosion-proof cover mechanism on a smelting furnace. Background technique: [0002] The explosion-proof device of the smelting furnace is usually an opening on the pipe, and an explosion-proof cover is installed at the opening. When the pressure in the furnace is too high, the explosion-proof cover is opened to protect it. After the pressure in the furnace is normal, the manual operation makes the explosion-proof cover close. However, this kind of explosion-proof device cannot automatically reset and close after the explosion-proof cover is opened, and must be completed manually. operation, it is necessary to improve it. [0003] In view of the above-mentioned defects, the designer actively researches and innovates in order to create an explosion-proof cover mechanism on the smelting furnace of a new structure, so that it has more industrial utilization value. ...
