[0014] The utility model provides a powder metallurgy sintering furnace with exhaust gas purification function, which has the following

[0015] Beneficial effects:

[0016] 1. The utility model can use the purification component to prevent most powder metallurgy sintering furnaces from emitting a large amount of harmful smoke when sintering workpieces through the purification component arranged outside the main body, which affects the processing environment and the physical and mental health of the workers and pollutes the environment, resulting in the problem of reduced practicality of the powder metallurgy sintering furnace.

The impact on the environment and the physical and mental health of the workers, further improving the safety of the sintering furnace during use.

[0017] 2. The utility model can avoid the poor thermal insulation of most powder metallurgy sintering furnaces during use through the arrangement of processing components when the powder metallurgy sintering furnace with exhaust gas purification function is used. The processing components arranged inside the vacuum tank can cause the heat to be easily lost and more energy to be consumed during the sintering process, resulting in the inefficiency of the use of the powder metallurgy sintering furnace. The furnace body is fixedly installed inside the vacuum tank by tightening bolts, and the objects placed inside the furnace body are heated by the burner installed at the rear end of the furnace body. At the same time, the heat conduction plate added to the inner wall of the furnace body makes the heat dissipated by the burner more uniform, so that the objects can be heated uniformly. The heat preservation plate arranged on the inner wall of the furnace body makes the heat preservation of the sintering furnace better during use, thereby shortening the sintering time, thereby reducing the rapid loss of heat during the sintering process, and improving the use efficiency of the powder metallurgy sintering furnace.
