Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of metal parts, in particular to a heat treatment furnace used for processing metal parts. Background Art

[0002] Heat treatment furnace is a general term for industrial furnaces that perform various metal heat treatments on metal workpieces. It is the main equipment for heat treatment. Heat treatment furnaces are widely used in the production of metal materials such as steel, copper, and aluminum, such as removing residual stress inside metal materials and improving their mechanical properties. At the same time, it is also used in processes such as hardening quenching, tempering, nitriding, as well as sintering, casting, molten salt treatment, etc., to improve the physical, chemical and mechanical properties of materials.

[0003] Existing heat treatment furnaces will produce a large amount of flue gas containing harmful substances during operation. If these harmful substances are directly discharged into the atmosphere without being treated, they will cause serious pollution to the environment.

[0004] For example, a sucker rod heat treatment device disclosed in announcement number CN203728884U, in which the flue gas containing a large amount of waste heat discharged from the exhaust port can heat the air in the heat exchanger, and the flue gas is discharged only after the heat exchange. Although the flue gas in the heat treatment furnace will pass through the heat exchanger for heat exchange, the flue gas cannot be purified before discharge, resulting in impurities still contained in the flue gas, such as particulate matter, harmful gases, etc. Once these substances are discharged into the atmosphere, they will seriously pollute the surrounding environment and reduce the air quality, which will not only have an adverse impact on people's living environment, but may also cause damage to surrounding plants and ecosystems.

[0005] Therefore, it is necessary to invent a heat treatment furnace for metal parts processing to solve the above problems. Utility Model Content
