Problems solved by technology

[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, so it is necessary to solve these problems

Abstract

The invention relates to an explosion-proof device of a smelting furnace. The explosion-proof device comprises a corner pipeline; one end of the pipeline communicates with a furnace chamber channel, and the other end of the pipeline communicates with a smoke discharging channel; an explosion-proof opening is formed in the pipeline; an explosion-proof cover is arranged at the upper end of the explosion-proof opening; elastic devices are arranged on the two sides of the explosion-proof opening; the lower ends of the two elastic devices are fixedly connected to the pipeline, and the upper ends ofthe elastic devices are fixedly connected to the explosion-proof cover; a sealing ring is arranged at the edge of the upper end of the explosion-proof opening; a first magnetic ring is arranged on the outer circle of the sealing ring; a second magnetic ring is arranged on the explosion-proof cover and is located above the position, corresponding to the first magnetic ring, of the first magnetic ring; the position, close to the explosion-proof opening, of the pipeline is sleeved with a refrigerating ring; a temperature relay is arranged on the pipeline; and the refrigerating ring is connectedto a power source through the temperature relay. Compared with the prior art, the explosion-proof device has the advantages of being simple in structure, stable in operation, capable of automaticallyclosing the smelting furnace, good in sealing performance and capable of lowering the explosion probability of the explosion-proof cover.

Description

technical field [0001] The invention relates to the technical field of mineral smelting, in particular to an explosion-proof device for 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, so it is necessary to solve these problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smelting furnace explosion-proof device with simple structure, stable operation, automatic closing of the smelting furnace and good...
