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 with a bell. The explosion-proof device with the bell comprises a corner pipeline. One end of the corner pipeline communicates with a furnace chamberchannel. The other end of the pipeline communicates with a smoke exhaust channel. The pipeline is provided with an explosion-proof opening. The upper end of the explosion-proof opening is provided with an explosion-proof cover. The two sides of the explosion-proof opening are provided with elastic devices. The lower ends of the two elastic devices are fixedly connected with the pipeline. The upper ends of the elastic devices are fixedly connected with the explosion-proof cover. The edge of the upper end of the explosion-proof opening is provided with a ring of sealing ring. One ring of the exterior of the sealing ring is provided with a first magnetic ring. The explosion-proof cover is provided with a second magnetic ring. The second magnetic ring is located on the corresponding upper portion of the first magnetic ring. A supporting rod is arranged at the position, close to the explosion-proof opening, of the pipeline, and the supporting rod is provided with a bell and fixedly connected with the pipeline. Compared with the prior art, the explosion-proof device with the bell is simple in structure and stable in operation, a smelting furnace can be closed automatically, and sealingperformance is good; and when the explosion-proof cover is opened through explosion, the bell is triggered to ring, and operators are reminded of conducting processing.

Description

technical field [0001] The invention relates to the technical field of mineral smelting, in particular to a bell explosion-proof device. 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 sealing performanc...
