One end of the power rod 503 passes through the fixed plate 502 and is fixedly connected to the output end of the motor 501. The power rod 503 is rotatably connected to the fixed plate 502.

[0023] In this embodiment, when in use, the air inlet end of the air inlet pipe 2 is connected to the oil fume pipe, so that the oil fume enters the air inlet pipe 2 through the oil fume pipe. At this time, the fan 9 is working. The fan 9 is an existing T35-11 axial flow fan 9. The gas entering the air inlet pipe 2 enters the oil fume purifier housing 1 through the fan 9. The oil fume enters the oil fume purifier housing 1 through the air inlet pipe 2 and preferentially passes through the annular filter 4. The annular filter 4 is made of stainless steel in the prior art. At this time, the motor 501 is started, and the motor 501 drives the fixed rod to rotate slowly. The fixed rod can drive the support assembly 6 and the annular filter 4 to rotate, so that the oil fume passes through the slowly rotating annular filter 4 and passes through the annular filter. The annular filter 4 intercepts oil droplets and impurities in the flue gas, so that the oil droplets and impurities in the flue gas remain on the outer surface and inner surface of the annular filter 4. At this time, the cleaning component 7 is used to scrape the oil droplets and impurities remaining on the outer surface and inner surface of the rotating annular filter 4, so that the scraped oil droplets move downward along the cleaning component 7 and the annular filter 4, and fall into the collecting component 8, and the oil droplets and impurities are collected by the collecting component 8. The filtered flue gas passes through the annular filter 4, passes through the fan 9, and is transported to the filter component 10. The flue gas passing through the annular filter 4 is secondary filtered by the filter component 10, and the flue gas purified by the filter component 10 is discharged through the outlet pipe 3.

[0024] Specifically, the support assembly 6 includes a support frame 601 and a support rod 602. The support frame 601 is fixedly installed at the bottom of the annular filter 4. One end of the support rod 602 is fixedly connected to the support frame 601, and the other end is connected to the power rod 503 through a bolt.

[0025] In this embodiment, when the power rod 503 rotates, the power rod 503 drives the support rod 602 to rotate synchronously, and the support rod 602 drives the support frame 601 and the annular filter 4 to rotate synchronously. When disassembly is required, the staff no longer bolts the support rod 602 to the power rod 503, which facilitates subsequent disassembly and cleaning by the staff.

[0026] Specifically, the cleaning assembly 7 includes a first connecting rod 701, a first scraper 702, a second connecting rod 703 and a second scraper 704. One end of the first connecting rod 701 and the second connecting rod 703 are fixedly connected to the fixed plate 502. The first scraper 702 is connected to the first connecting rod 701 by a bolt, and the second scraper 704 is connected to the second connecting rod 703 by a bolt. The first scraper 702 is in contact with the inner surface of the annular filter 4, and the second scraper 704 is in contact with the outer surface of the annular filter 4.

[0027] In this embodiment, when the annular filter 4 rotates, because the first scraper 702 and the second scraper 704 are respectively in contact with the inner surface and outer surface of the annular filter 4, when the annular filter 4 rotates, the first scraper 702 and the second scraper 704 respectively scrape the oil droplets and impurities on the inner surface and outer surface of the annular filter 4, so that the scraped oil droplets and impurities move downward along the first scraper 702 and the second scraper 704 due to gravity, and drip into the collecting assembly 8. The first scraper 702 is connected to the first connecting rod 701, and the second scraper 704 is connected to the second connecting rod 703 by bolts, which facilitates the subsequent disassembly of the first scraper 702 and the second scraper 704 for cleaning.

[0028] Specifically, the collection component 8 includes a rectangular groove 801 and a collection box 802. The rectangular groove 801 is opened at the bottom of the oil fume purifier shell 1 and is located directly below the annular filter 4. The collection box 802 is set in the rectangular groove 801 and slides with the inner wall of the rectangular groove 801. The top of the collection box 802 is opened.

[0029] In this embodiment, the dripping oil droplets and impurities are allowed to enter the collection box 802 and accumulate in the collection box 802, making it convenient for staff to clean them up.

[0030] Specifically, the filter assembly 10 includes a plurality of slots 1001 and a plurality of activated carbon plates 1002 . The plurality of slots 1001 are equidistantly arranged at the bottom of the oil fume purifier housing 1 . The plurality of activated carbon plates 1002 are respectively arranged in the corresponding slots 1001 and slideably fit with the corresponding slots 1001 .

[0031] In this embodiment, when the flue gas passing through the annular filter 4 contacts the activated carbon plate 1002 and passes through the activated carbon plate 1002, the activated carbon is used to adsorb the oil smoke particles, which can effectively remove the odor and achieve the purpose of purification. When the activated carbon plate 1002 needs to be replaced, the staff pulls the activated carbon plate 1002, and the activated carbon plate 1002 moves along the slot 1001, and the new activated carbon is placed into the slot 1001.

[0032] Specifically, one side of the oil fume purifier housing 1 is an opening, and two rotating sealing doors 11 are provided at the opening on the side of the oil fume purifier housing 1 .

[0033] In this embodiment, when cleaning or replacement is required, the staff rotates the two sealing doors 11, and unbolts the power rod 503 and the support rod 602, the first connecting rod 701 and the first scraper 702, and the second connecting rod 703 and the second scraper 704. At this time, the staff takes out the annular filter 4 and the support frame 601, the support rod 602, the first scraper 702 and the second scraper 704 for cleaning, and takes out the activated carbon plate 1002 from the slot 1001 for replacement. When the replacement, cleaning and contact installation are completed, the staff closes the two sealing doors 11, and the sealing doors 11 are against the activated carbon plate 1002 to prevent the activated carbon plate 1002 from moving in the slot 1001 and detaching from the slot 1001.
