[0002] Heat treatment refers to a metal heat processing technology in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and performance. During the heat treatment process, heating and cooling will produce a large amount of harmful smoke. During the initial treatment, the smoke needs to be filtered, and the filtered smoke can be processed in the next step until the smoke release standard is met. In today's filtration system, most of them require filter sheets, which are installed in the pipeline for filtration. However, this requires re-disassembly and re-installation for cleaning, which greatly increases the difficulty of cleaning. Utility Model Content

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in FIG1-2, a mechanical parts heat treatment exhaust gas cleaning device includes a hollow vent pipe 10, characterized in that: a filter disc 11 is fixed to the middle part of the vent pipe 10, and an electromagnet 17 is also fixed to the outer peripheral side of the vent pipe 10, and the electromagnet 17 is located at the opening of the filter disc 11, and corresponding to the electromagnet 17, a filter assembly is provided in the filter disc 11;

[0017] The filter assembly includes a rotating shaft 18 that passes through the filter disc 11. The rotating shaft 18 extends to the outside. The rotating shaft 18 is installed on the filter disc 11 through a bearing 20. A rotating handle 19 is installed on the outer part of the rotating shaft 18. The rotating shaft 18 is rotatably connected to the filter disc 11 through the bearing 20. At least two receiving plates 12 are fixed on the rotating shaft 18. A filter plate 13 is slidably installed inside the receiving plate 12 through a spring 15. A filter cavity 14 is opened inside the receiving plate 12. The filter plate 13 slides in the filter cavity 14. The end face of the filter plate 13 on one side away from the rotating shaft 18 is a circular surface, which coincides with the curve of the ventilation pipe 10. A plurality of filter holes are provided on the surface of the filter plate 13. An arc-shaped magnetic ring 16 is fixed on the inner wall of the ventilation pipe 10. The filter plate 13 is adsorbed by the magnetic ring 16 so that the filter plate 13 filters the gas.

[0018] The interior of the filter disc 11 is hollow, and the receiving plate 12 rotates in the hollow space thereof and is connected to the hollow space in the vent pipe 10. A fan-shaped notch is also provided on the filter disc 11, and the number of the receiving plates 12 allows the fan-shaped notch to be blocked when the filter disc 11 is rotated to any position.

[0019] When in use, install the vent pipe 10 at the smoke outlet, place the bend of the vent pipe 10 upward, and the smoke flows to the outside through the vent pipe 10. When the smoke passes through the bend of the vent pipe 10, it can be filtered by the filter plate 13. When the filter plate 13 is used for a long time, the filter holes on it are blocked. The rotating handle 19 can be rotated to drive the rotating shaft 18 to rotate the receiving plate 12. The receiving plate 12 rotates to make the current filter plate 13 separate from the magnetic ring 16. When the filter plate 13 is separated, the filter plate 13 is pulled back into the filter chamber 14 by the stretched spring 15, and then rotated to the filter chamber 14. The notch of the filter disc 11 is opened, and the electromagnet 17 is started to suck out the filter plate 13 at the notch, and then it is rinsed and cleaned. After cleaning, the electromagnet 17 is turned off, and the filter plate 13 is retracted into the capacity plate 12. Then the rotating shaft 18 is rotated to replace the next filter plate 13 that needs to be cleaned. Then the cleaned filter plate 13 is rotated again to re-enter the filter disc 11. Then, when it passes through the magnetic ring 16, the filter plate 13 will be sucked out by the magnetic ring 16 and then adsorbed on the magnetic ring 16. The flue gas is filtered by the filter plate 13, which greatly facilitates the cleaning process of the equipment.

[0020] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
