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

Abstract

The invention relates to an explosion protection device of a smelting furnace. The explosion protection device comprises a pipeline with a corner, wherein one end of the pipeline is communicated with a furnace chamber passage, and the other end of the pipeline is communicated with a smoke exhaust passage; the pipeline is provided with an explosion protection opening; the upper end of the explosion protection opening is provided with an explosion protection cover; elastic devices are arranged on the two sides of the explosion protection opening; the lower ends of the two elastic devices are fixedly connected with the pipeline, and the upper ends of the elastic devices are fixedly connected with the explosion protection cover; the edge of the upper end of the explosion protection opening is provided with a circle of seal ring; a first magnetic ring is arranged on the circle on the outer side of the seal ring; the explosion protection cover is provided with a second magnetic ring; the second magnetic ring is positioned in the corresponding upper space of the first magnetic ring. Compared with the prior art, the explosion protection device has the advantages of simple structure, stable operation, capability of automatically closing the smelting furnace and good sealing property.

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; "A smelting furnace explosion-proof device" with application number 201220607147.3 in the existing technology also has the following defects: 1. The extension spring is placed in the explosion-proof port, which is easy to corrode and the structure is easily damaged, which then affects nor...
