Explosion-proof structure for smelting furnace

Abstract

The invention discloses an explosion-proof structure for a smelting furnace. The structure comprises a furnace body. A pressure relief hole is formed in the furnace body; anti-explosion pipes are mounted on the outer wall of the furnace body; an anti-explosion cover is inserted into the anti-explosion pipes; a guide column is mounted on the anti-explosion cover; a positioning disc is inserted intothe anti-explosion pipes; a guide hole is formed in the center of the positioning disc; and the guide column is inserted into the guide hole. A first pressure spring is inserted into the guide columnin a sleeving mode; pressure relief grooves are formed in the side walls of the anti-explosion pipes; limiting holes are formed in the side wall of the guide column; a containing groove is formed inthe inner wall of the guide hole; a limiting rod is inserted into the containing groove; an inserting rod is mounted at one end of the limiting rod and sleeved by a second compressed spring in an inserted mode; the two ends of the second compressed spring abut against the limiting rod and the side wall of the containing groove respectively; and annular positioning plates are mounted on the limiting rod. Annular grooves are formed in the containing groove, the positioning plates are inserted into the annular grooves, electromagnets are fixed in the annular grooves, and the positioning plates are attracted to the electromagnets. According to the explosion-proof structure for the smelting furnace, the automatic closing of the anti-explosion cover can be realized after explosion-proof pressurerelief.

Description

Technical field: [0001] The invention relates to the technical field of smelting furnaces, in particular to an explosion-proof structure for smelting furnaces. 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 a new type of explosion-proof structure for smelting furnaces, so that it has more industrial value. Invention content: [0004] The ...
