Problems solved by technology

[0002] The secondary combustion furnace in the prior art is sealed in the furnace, and the combustion causes high temperature and high pressure in the furnace body. If it cannot be discharged in time, it will easily cause the furnace body to burst, causing unnecessary personnel and property losses, and the existing secondary combustion furnace has a complex structure. Insufficient combustion, room for improvement

Abstract

A secondary combustion furnace comprises a vertically-arranged barrel-shaped furnace body. An anti-explosion end cover is arranged at the top end of the furnace body and made of a steel plate with the thickness being 10 cm. An anti-explosion opening is formed in the center of the anti-explosion end cover. An anti-explosion device is arranged in the anti-explosion opening and comprises a base embedded in the anti-explosion opening. A steel hook is arranged in the side wall of the base and fixedly connected with the anti-explosion end cover. A central hole is formed in the center of the base. An anti-explosion cover is arranged on the central hole. The tail end of the anti-explosion cover is inserted in the central hole. The anti-explosion cover is provided with a pressure relief pipe which comprises a vertical section and a conical amplification section. A sealing ball is arranged in the conical amplification section. The secondary combustion furnace is simple in structure, automatic pressure relief is conducted, the furnace body is effectively protected against explosion, and combustion is sufficient.

Description

Technical field [0001] The invention relates to the field of precious metal recovery equipment, in particular to a secondary combustion furnace. Background technique [0002] The existing secondary combustion furnace is sealed in the furnace, and the combustion produces high temperature and high pressure in the furnace body. If it cannot be discharged in time, it will easily cause the furnace body to burst, causing unnecessary personnel and property losses, and the existing secondary combustion furnace has a complicated structure. The combustion is not sufficient and needs to be improved. Summary of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a secondary combustion furnace with simple structure, automatic pressure relief, effective prevention of furnace body bursting and full combustion. [0004] In order to achieve the objective of the present invention, the following technical solutions are provided: a secondary combustion fu...
