[0036] like Figure 1-10 As shown, this embodiment of a chemical fiber friction granulation oil fume purification device includes a main body 1. A filter channel is provided inside the main body 1. A first filter system and a second filter system are provided inside the filter channel. The first filter system and the second filter system are arranged along the flow direction of the oil fume exhaust gas inside the main body 1. The first filter system is an activated carbon adsorption mesh 2, and the second filter system is a photocatalytic filter 3. During operation, the oil fume exhaust gas enters the filter channel from one end of the main body 1. First, the activated carbon adsorption mesh 2 adsorbs and removes particulate impurities in the oil fume exhaust gas. Then, it undergoes photocatalytic decomposition through the photocatalytic filter 3. Finally, it is discharged from the other end of the main body 1, thereby achieving comprehensive purification treatment of the oil fume exhaust gas.

[0037] The main body 1 includes a body 11. The first filtration system and the second filtration system are both located inside the body 11. Both ends of the body 11 are connected to a flow guide 12. The side of the flow guide 12 away from the body 11 is connected to a connector 13. During installation, one connector 13 is connected to the oil fume exhaust gas inlet pipe, and the other connector 13 is connected to the oil fume exhaust gas outlet pipe.

[0038] The tap joint 13 is movably sleeved with a telescopic sleeve 14. When the tap joint 13 is connected to the oil fume exhaust pipe, the telescopic sleeve 14 slides outward, so that the telescopic sleeve 14 moves to the connection between the tap joint 13 and the oil fume exhaust pipe, which plays a role in sealing and protecting the connection between the two, and preventing the oil fume exhaust from leaking.

[0039] The main body 1 is provided with a cleaning mechanism 4. The cleaning mechanism 4 includes a mounting plate 41, which is sealed and fixedly connected to the inner wall of the main body 1. The mounting plate 41 is provided with a plurality of filter holes 42. Multiple activated carbon adsorption nets 2 are provided, and the multiple activated carbon adsorption nets 2 correspond one-to-one with the multiple filter holes 42. The activated carbon adsorption nets 2 are installed in the filter holes 42. A cleaning component 43 is connected to the mounting plate 41.

[0040] The cleaning component 43 includes a rotating tube 431 that passes through a mounting plate 41 and is perpendicular to the mounting plate 41. Multiple filter holes 42 are evenly distributed circumferentially around the rotating tube 431. One end of the rotating tube 431 is sealed, and the other end is fitted with a connecting cover 432. The connecting cover 432 rotates and is sealed to the rotating tube 431. A drain pipe 433 is provided on the connecting cover 432, extending to the outside of the main body 1 and fixedly connected to the main body 1. A drive system (not shown in the diagram) is connected to the sealed end of the rotating tube 431, enabling the rotating tube 431 to rotate. Here, the drive system can be a motor. A collection cover 434 is provided on one side of the rotating tube 431, with an opening on the side of the collection cover 434 closest to the second filtration system. The opening side of the collection cover 434 is sealed to the side of the mounting plate 41 furthest from the second filtration system. The collection hood 434 is connected to the rotating pipe 431 via the connecting pipe 435. During operation, the oil fume exhaust gas passes through the filter holes 42, and the particulate impurities in the oil fume exhaust gas are intercepted by the activated carbon adsorption net 2. The particulate impurities are located on the side of the activated carbon adsorption net 2 away from the second filtration system. When the activated carbon adsorption net 2 needs to be cleaned, the rotating pipe 431 is rotated by the drive system to rotate a certain angle, so that the collection hood 434 covers the activated carbon adsorption net 2 that needs to be cleaned. At this time, the air between the second filtration system and the mounting plate 41 passes through the filter holes 42 here and enters the collection hood 434, which realizes the back-blowing of the activated carbon adsorption net 2. The air in the collection hood 434 is sequentially transported from the connecting pipe 435, the rotating pipe 431 and the connecting hood 432 to the drain pipe 433. Under the action of the airflow, the particulate impurities intercepted on the activated carbon adsorption net 2 are blown away and enter the drain pipe 433 with the airflow. In this way, the cleaning of particulate impurities on the activated carbon adsorption net 2 is achieved.

[0041] When it is necessary to clean other activated carbon adsorption nets 2, the rotating tube 431 is rotated at the corresponding angle so that the collection cover 434 covers the other activated carbon adsorption nets 2 that need to be cleaned.

[0042] In this way, when cleaning the activated carbon adsorption net 2, the particulate impurities removed during cleaning can be prevented from being trapped in the activated carbon adsorption net 2 again with the flow of oily fumes, thus ensuring the stability of continuous use of the activated carbon adsorption net 2.

[0043] The cleaning component 43 also includes multiple tapping units 436, each tapping unit 436 corresponding to a multiple filter holes 42. The tapping units 436 are located between the mounting plate 41 and the second filtration system. The tapping units 436 are used to tap the activated carbon adsorption mesh 2.

[0044] The tapping unit 436 includes a tapping plate 4361, which is arranged opposite to the filter screen. A driving component is connected to the tapping plate 4361, which enables the tapping plate 4361 to move back and forth towards the activated carbon adsorption screen 2.

[0045] The driving component includes a connecting frame 4362, on which a striking plate 4361 is fixedly mounted. A guide rod 4363 is movably mounted on the connecting frame 4362. One end of the guide rod 4363 is fixedly mounted on a mounting plate 41, and the other end is fixedly mounted on an electromagnet 4364. The connecting frame 4362 is a magnet. A gap is provided between the connecting frame 4362 and the mounting plate 41. The connecting frame 4362 is connected to the mounting plate 41 by an elastic element, which is a spring 4365. The spring 4365 is located between the connecting frame 4362 and the mounting plate 41, and is sleeved on the guide rod 4363. Both ends of the spring 4365 are respectively connected to the connecting frame 4362 and the mounting plate 41. Multiple connecting frames 4362 are provided, specifically two.

[0046] When cleaning particulate impurities on the activated carbon adsorption mesh 2, the electromagnet 4364 is intermittently energized. When the electromagnet 4364 is energized, a repulsive force is generated between the electromagnet 4364 and the connecting frame 4362, causing the connecting frame 4362 to move on the guide rod 4363 and causing the spring 4365 to deform. The movement of the connecting frame 4362 drives the tapping plate 4361 to move towards the activated carbon adsorption mesh 2 and come into contact with it. When the electromagnet 4364 is de-energized, the elastic action of the spring 4365 causes the connecting frame 4362 to move in the opposite direction to reset, which in turn drives the tapping plate 4361 to reset. This process is repeated, causing the tapping plate 4361 to tap the activated carbon adsorption mesh 2 repeatedly, causing the particulate impurities adsorbed on the activated carbon adsorption mesh 2 to fall downwards under the action of inertia, thereby improving the cleaning effect of the activated carbon adsorption mesh 2.

[0047] Of course, an air extraction system can also be connected to the drain pipe 433 to improve the ability of the connecting cover 432 to adsorb particulate impurities on the activated carbon adsorption mesh 2.

[0048] The collection cover 434 includes a cover body 4341 and a moving tube 4342. The cover body 4341 is connected to a connecting tube 435. One side of the cover body 4341 is open. The moving tube 4342 is sleeved on the open end of the cover body 4341. The moving tube 4342 is slidably and sealingly connected to the cover body 4341. The moving tube 4342 is driven by a cylinder 4343 to move towards or away from the mounting plate 41. When the rotating tube 431 needs to rotate, the cylinder 4343 drives the moving tube 4342 to move away from the mounting plate 41 and create a gap between the moving tube 4342 and the mounting plate 41. After the rotating tube 431 has finished rotating, the cylinder 4343 drives the moving tube 4342 to move in the opposite direction, so that the moving tube 4342 is sealed and fitted with the mounting plate 41. In this way, wear between the collection cover 434 and the mounting plate 41 can be avoided when the rotating tube 431 rotates, which would affect the sealing performance between the collection cover 434 and the mounting plate 41.

[0049] In summary, when removing particulate impurities from the activated carbon adsorption mesh 2, the backflushing of the activated carbon adsorption mesh 2 prevents the cleaned particulate impurities from being trapped again in the activated carbon adsorption mesh 2 with the flow of oily fumes, ensuring the stability of continuous use of the activated carbon adsorption mesh 2. Moreover, by tapping the activated carbon adsorption mesh 2, it is easy for particulate impurities to separate from the activated carbon adsorption mesh 2, thereby improving the cleaning effect of the activated carbon adsorption mesh 2.

[0050] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
