Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, a dust removal device for a vacuum pump includes a condenser unit 1, a circulation unit 2, and a support unit 3. The condenser unit 1 includes a condenser shaft 103 rotatably mounted within a support housing 301. A condenser liner 107 is slidably mounted on the condenser shaft 103. A condenser gravity ring 104 is fixedly mounted on the condenser liner 107. The other end of the condenser gravity ring 104 is fixedly mounted on the condenser shaft 103. A condenser return spring 105 is disposed between the condenser gravity ring 104 and the condenser liner 107. A condenser rotating piece 102 is slidably mounted on the other end of the condenser shaft 103. The condenser rotating piece 102 is rotatably mounted on a condenser swing shaft 101, which is rotatably mounted on the support housing 301. The circulation unit 2 includes a circulation sliding plug 201 that slidably cooperates with the condenser swing shaft 101. The circulation sliding plug 201 is slidably mounted within a circulation housing 202. One end of the circulation housing 202 is connected to the support housing 301 via a second circulation pipe 204, and the other end of the circulation housing 202 is connected to the support housing 301 via a first circulation pipe 203. The support portion 3 includes a support exhaust port 304 , a support air inlet 302 , a support shell 301 , and a support drain valve 303 . The support exhaust port 304 is provided at the upper portion of the support shell 301 , and the support air inlet 302 is provided at the bottom portion of the support shell 301 .

[0024] like Figures 1 to 8As shown, a fan blade is provided in the middle of the condensation tank 107 for driving the condensation tank 107 to rotate; scrapers are provided on the top and bottom of the condensation tank 107; the drain valve 303 is supported and connected to the bottom of the support shell 301 through threads; a condensation filter 106 is fixedly provided at the bottom of the condensation tank 107, and a through hole for gas to pass through is provided on the condensation filter 106; a detachable filter is provided in the support exhaust port 304 and the support air inlet 302; the support shell 301 consists of two layers, inner and outer, and the space between the inner and outer layers is filled with liquid for condensation.

[0025] like Figures 1 to 8 As shown, the utility model discloses a dust removal device for a vacuum pump, and its working principle is as follows: the support air inlet 302 end of the device is installed on the vacuumed equipment, and the support exhaust port 304 end is installed on the vacuum pump. The vacuum pump starts to work and extracts the gas in the vacuumed equipment. The gas enters the interior of the support shell 301 through the support air inlet 302 and the filter provided in the support air inlet 302, filters the ash impurities in the gas, and is discharged into the vacuum pump through the support exhaust port 304 and the filter in the support exhaust port 304 to prevent impurities from affecting the vacuum pump. During the flow of gas, it is in full contact with the interior of the support shell 301. The condensate in the supporting shell 301 condenses the liquid in the gas. At the same time, the flowing gas pushes the condensation tank 107 to rotate through the fan blades arranged in the middle of the condensation tank 107. The rotation of the condensation tank 107 drives the condensation shaft 103 to rotate. When the rotation speed of the condensation tank 107 accelerates, the condensation gravity ring 104 pulls the condensation tank 107 toward the condensation filter 106 end under the action of centrifugal force. The condensed liquid in the supporting shell 301 is scraped off by the scraper arranged on the condensation tank 107 to avoid affecting the subsequent condensation effect. The scraped liquid flows into the bottom of the supporting shell 301 and gathers. After a certain period of time, the operator discharges the liquid through the supporting drain valve 303.

[0026] When the condensation shaft 103 rotates, it drives the condensation rotating plate 102 to make the condensation swing shaft 101 swing. The swing of the condensation swing shaft 101 drives the circulation sliding plug 201 to slide in the circulation shell 202. When the circulation sliding plug 201 slides, it drives the condensate in the supporting shell 301 to flow through the circulation pipe 1 203 and the circulation pipe 2 204 to prevent the condensate from gathering and affecting the condensation effect.
