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 a nitrogen generation explosion-proof device. The nitrogen generation explosion-proof device comprises a pipeline at the corner. One end of the pipeline communicates with a furnace chamber channel. The other end of the pipeline communicates with a flue gas discharge channel. The pipeline is provided with an explosion-proof opening. An explosion-proof cover is arranged at the upper end of the explosion-proof opening. The two sides of the explosion-proof opening are both provided with elastic devices. The lower ends of the two elastic devices are both fixedly connected with the pipeline. The upper end of each elastic device is fixedly connected with the explosion-proof cover. A seal ring is arranged on the edge of the upper end of the explosion-proof opening. A firstmagnetic ring is arranged outside the seal ring. A second magnetic ring is arranged on the explosion-proof cover. The second magnetic ring is correspondingly located above the first explosion-proof ring. The portion, close to the explosion-proof opening, of the pipeline is provided with a nitrogen generation device. Compared with the prior art, the nitrogen generation explosion-proof device is simple in structure, stable in operation, capable of automatically closing a smelting furnace and good in seal performance and lowers the burst 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 generating nitrogen. 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 goo...
