[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0030] See also Figure 1 - Figure 3 The utility model provides a dust removal device, including a tank body 100, a dust filter assembly 200, a sleeve 300, an ultraviolet lamp tube 400 and an annular scraper 500; an air inlet pipe 110 is provided at the lower part of the tank body 100, and an exhaust pipe 120 is provided at the top of the tank body 100; the dust filter assembly 200, the dust filter assembly 200 is arranged in the middle part of the tank body 100; the sleeve 300, the sleeve 300 is inserted at the top of the tank body 100, and one end of the sleeve 300 extends into the tank body 100; the ultraviolet lamp tube 400, the ultraviolet lamp tube 400 is movably inserted in the sleeve 300; the annular scraper 500, the annular scraper 500 is arranged on the side of the sleeve 300 extending into the tank body 100, and the annular scraper 500 is used to approach and scrape the outer wall of the ultraviolet lamp tube 400.

[0031] When in use, first insert the ultraviolet lamp 400 into the sleeve 300, and activate the above-mentioned dust removal device normally; when it is necessary to remove the dust on the ultraviolet lamp 400, the ultraviolet lamp 400 can be pulled out for cleaning to prevent the dust from affecting the light transmittance and the effect of removing exhaust gas; it can also be pulled back and forth on the annular scraper 500, and the dust can be cleaned by scraping the outer wall of the ultraviolet lamp 400 with the help of the annular scraper 500. It should be pointed out that these dusts will fall on the inner wall of the tank 100 and the dust filter assembly 200 in a dry state. Since the dry state of the dust will not cause obvious and difficult-to-remove blockage to the pores of the dust filter assembly 200, that is, the overall anti-blockage effect can be effectively improved, and there is no need to frequently replace the dust filter assembly 200.

[0032] Furthermore, in one embodiment of the present invention, the inner diameter of the annular scraper 500 is clearance-matched with the outer wall of the ultraviolet lamp tube 400, so as to avoid scratching the ultraviolet lamp tube 400. It should be noted that the material of the annular scraper 500 can be preferably rubber, so as to avoid scratching.

[0033] Furthermore, in an embodiment of the present invention, at least eight sleeves 300 are provided, and the ultraviolet lamp tubes 400 correspond to the sleeves 300 one by one, which can effectively improve the effect of removing exhaust gas.

[0034] Furthermore, in one embodiment of the present invention, the dust filter assembly 200 includes a primary filter 210 and a secondary filter 220, wherein the primary filter 210 is disposed below the secondary filter 220, and the mesh number of the primary filter 210 is smaller than the mesh number of the secondary filter 220. Specifically, dust can be filtered in stages through the primary filter 210 and the secondary filter 220, which can effectively improve the filtering efficiency and filtering effect.

[0035] Furthermore, in one embodiment of the present invention, the secondary filter screens 220 are arranged in pairs, and both the secondary filter screens 220 and the primary filter screens 210 are connected to the tank body 100 in a pull-out manner, which facilitates quick replacement and cleaning.

[0036] In order to prevent dust from overflowing, in one embodiment of the present invention, one end of the primary filter screen 210 and the secondary filter screen 220 both extend out of the tank body 100, and the primary filter screen 210 and the secondary filter screen 220 are arranged at an angle.

[0037] Furthermore, in one embodiment of the present invention, a support frame 600 is provided at the bottom of the tank body 100, so that the tank body 100 can be effectively supported and more expansion pieces can be conveniently arranged.

[0038] Furthermore, in one embodiment of the present invention, a material discharge port 130 is connected to the bottom of the tank body 100 , so that it is convenient to clean the materials in the tank body 100 .

[0039] Furthermore, in one embodiment of the present invention, a side wall of the tank body 100 is provided with an openable and closable maintenance door 140 .

[0040] Furthermore, in one embodiment of the present invention, a side wall of the tank body 100 is further provided with an observation window 150 .

[0041] When the dust removal device is used, first, the waste gas containing dust is discharged into the tank body 100 through the air inlet pipe 110. The plane where the air inlet pipe 110 is located is provided with filter water, so that part of the dust and waste gas can be adsorbed; then, the waste gas rises and passes through the primary filter 210 and the secondary filter 220 to complete the filtration, at which time most of the dust has been adsorbed or filtered; then, the exhaust gas will be decomposed by the ultraviolet lamp tube 400 located above the secondary filter 220, and finally discharged through the exhaust pipe 120. Since the ultraviolet lamp tube 400 is movably sleeved on the sleeve 300, and the sleeve 300 is also provided with an annular scraper 500, the ultraviolet lamp tube 400 can be easily taken out for cleaning, or pulled back and forth in the sleeve 300, and its outer wall is cleaned with the help of the annular scraper 500. These dusts will fall on the inner wall of the tank body 100 or the secondary filter 220 in a dry state, and will not cause substantial blockage to the secondary filter 220. That is, they will not affect the filtering performance of the secondary filter 220 and the primary filter 210 as a whole, and there is no need to frequently replace the dust filter assembly 200.

[0042] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
