Meanwhile, a processing efficiency is high; the vacuum pumping machine can be prevented from corrosion; and the exhaust gas is environment-friendly.

Description

technical field [0001] The invention relates to a three-chamber vacuum furnace for anti-corrosion sewage discharge liquid purification monitoring operation, which belongs to the technical field of vacuum furnaces. Background technique [0002] At present, the existing vacuum furnace includes a cooling chamber and a heating chamber, and the cooling chamber and the heating chamber are separated by a partition wall; a gas quenching chamber and an oil quenching chamber are arranged inside the cooling chamber, and the gas quenching chamber is provided with an air-filled quick-cooling mechanism. source, while the oil quenching chamber performs oil quenching through the oil quenching tank. The inside of the heating chamber includes a heating chamber platform and a material frame. The material frame is placed on the heating chamber platform. At the same time, one or more heating tubes are evenly arranged in the heating chamber along the circumferential direction, and a vacuum mechan...

AI Technical Summary

Problems solved by technology

[0003] 1. During oil quenching, because the processed materials are put into the oil quenching oil tank, the oil surface is heated unevenly and the oil splashes, so accidents are prone to occur

[0004] 2. The inside of the heating chamber is statically heated by the heating tube, so it is easy to cause the material to be heated unevenly, and a good processing effect cannot be achieved.

[0005] 3. The heat insulation effect of the furnace wall of the heating chamber of this design is not good, and the temperature between the cooling chamber and the heating chamber cannot achieve good heat insulation, so the heat dissipation is serious and the energy consumption is high

[0006] 4. The vacuum furnace of this design needs to open the heating chamber when the material is heated and processed. Therefore, every time the material is processed, the heating chamber must be evacuated and heated again, which wastes a lot of energy, which is uneconomical and expensive. Environmental friendly

[0007] 5. When processing materials, this kind of heating furnace can only be processed manually, so its labor cost is high. At the same time, due to the limitation of workers' skills, the various processes cannot be well connected during processing, resulting in processing There are many defective products after the material

[0008] 6. When the existing vacuum furnace is vacuumed, a large amount of dust will be generated when the materials in the cooling chamber and heating chamber are heated or cooled, so when the vacuuming mechanism is vacuumed, the vacuuming mechanism is easy to corrode

[0009] 7. Due to the existing vacuum furnace, when the material is heated in the heating chamber or cooled in the cooling chamber, a large amount of smoke and dust will be generated, and these gases containing a large amount of smoke and dust will be directly discharged into the air, polluting the environment, so it is not environmentally friendly
