[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-8 A silicon carbide falling film absorber is shown, comprising a falling film absorber 1, a plurality of air inlet pipes 2 are fixedly connected to the falling film absorber 1, a semicircular groove 3 is provided on the air inlet pipe 2, a semicircular block 4 is inserted inside the semicircular groove 3, a filter plate 5 is fixedly connected to the inner wall of the semicircular block 4, a plurality of plug-in grooves 6 are provided on the falling film absorber 1, a circular plate 7 is rotatably inserted inside the plug-in groove 6, a pair of externally threaded pipes 8 are fixedly connected to the outer ends of the circular plates 7, an internally threaded pipe 9 is threadedly connected to the outer ends of the externally threaded pipes 8, a moving block 10 is provided inside the internally threaded pipe 9, a limiting ring 11 is fixedly connected to the outer ends of the moving block 10, a limiting groove 12 rotatably connected to the limiting ring 11 is provided on the inner wall of the internally threaded pipe 9, and the limiting ring 11 is used to facilitate the moving block 10 to move together with the internally threaded pipe 9;

[0027] A pair of side ends of the semicircular block 4 are provided with fixed grooves, and a sealing block 13 is fixedly connected to the inner wall of the fixed groove. The ends of the pair of sealing blocks 13 that are far away from each other are tightly fitted with the inner wall of the semicircular groove 3. The outer end of the filter plate 5 is in contact with the inner wall of the intake pipe 2. The end of the circular plate 7 close to the falling film absorber 1 is fixedly connected with a fixed ring 16, and the fixed ring 16 can prevent the circular plate 7 from separating from the falling film absorber 1. A reinforcement groove 17 rotatably connected to the fixed ring 16 is provided on the inner wall of the plug-in groove 6. The lower end of the semicircular block 4 is fixedly A pair of sealing strips 14 are fixedly connected, and a sealing groove 15 movably inserted with the sealing strip 14 is opened on the inner wall of the semicircular groove 3. After the semicircular block 4 is inserted into the semicircular groove 3, the sealing strip 14 will enter the sealing groove 15, thereby improving the sealing of the semicircular groove 3. A magnetic coating 18 is coated on the inner wall of the plug-in groove 6, and a magnetic coating 2 19 is coated on the outer end of the semicircular block 4. When the magnetic coating 18 and the magnetic coating 2 19 are adsorbed together, the stability of the circular plate 7 in the plug-in groove 6 can be improved.

[0028] When in use, when the gas enters the intake pipe 2, the filter plate 5 is used to filter the gas to reduce the content of dust and foreign matter in the gas. After the filter plate 5 has been used for a period of time, the internal threaded tube 9 needs to be rotated to make it rotate and move up on the external threaded tube 8. At the same time, the internal threaded tube 9 will drive the limit ring 11 and the moving block 10 to move up and close to the circular plate 7. When the moving block 10 moves up, it will drive the semicircular block 4 and the filter plate 5 to move together. After the semicircular block 4 and the filter plate 5 are moved out of the semicircular groove 3, the circular plate 7 is rotated 180 degrees, and then the positions of the two semicircular plates 7 and the two filter plates 5 are swapped. Then the internal threaded tube 9 is rotated to make it move down until the unused filter plate 5 is installed inside the intake pipe 2, and the other used filter plate 5 is cleaned. Therefore, when the absorber is in use, it can filter and purify the gas, thereby improving the cleanliness of the gas.

[0029] The second implementation method:

[0030] Based on the first embodiment, this embodiment adds structures such as a protective cover 20, and the rest of the parts remain the same as the first embodiment.

[0031] Figure 4 and Fig. 9 It is shown that a protective cover 20 is sleeved on the filter plate 5, a magnetic block 1 21 is fixedly connected to the inner wall of the protective cover 20, a magnetic block 2 22 is fixedly connected to the outer end of the filter plate 5, and a handle is fixedly connected to the outer end of the protective cover 20.

[0032] When using the filter plate 5 to filter and purify the dust and foreign matter in the gas, the protective cover 20 needs to be sleeved on the spare filter plate 5. After the protective cover 20 is installed on the filter plate 5, a pair of side ends of the filter plate 5 will fit with the inner wall of the protective cover 20, so as to protect the filter plate 5. At the same time, the magnetic block 1 21 will be adsorbed together with the magnetic block 2 22 to improve the stability of the protective cover 20 on the filter plate 5.

[0033] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
