[0023] Embodiment 1:

[0024] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5, a mechanical impurity cleaning device for a vacuum oil pump, including a cleaning box 1, and further including: a filter screen 103 fixedly installed in the cleaning box 1, wherein a cleaning cavity 101 is provided above the filter screen 103 and a water storage cavity 102 is provided below the filter screen 103 in the cleaning box 1; a reciprocating lead screw 4 rotatably connected to the inner wall of the cleaning cavity 101, wherein a T-shaped scraper 402 is threadedly connected to the reciprocating lead screw 4, the T-shaped scraper 402 is in contact with the filter screen 103, and a driving part for driving the reciprocating lead screw 4 to rotate is provided on the side wall of the cleaning box 1; a connecting plate 601 arranged in the water storage cavity 102, wherein a jet nozzle 602 is fixedly connected to the connecting plate 601, the connecting plate 601 is fixedly connected to the T-shaped scraper 402 through a connecting rod 403, a guiding groove 404 communicating with the cleaning cavity 101 and the water storage cavity 102 respectively is provided on the cleaning box 1, the connecting rod 403 is slidably connected in the guiding groove 404, and sewage discharge grooves 405 communicating with the cleaning cavity 101 are provided on both sides of the cleaning box 1; an air suction pump 6 fixedly installed on the cleaning box 1, and the output end of the air suction pump 6 is fixedly communicated with the jet nozzle 602 through a second pipeline 603.

[0025] A water extraction pump 3 is fixedly installed on the outer wall of the cleaning box 1, a plurality of spray nozzles 303 are fixedly installed on the top inner wall of the cleaning cavity 101, a water delivery cavity 302 communicating with the spray nozzles 303 is provided on the top of the cleaning box 1, the input end of the water extraction pump 3 is fixedly communicated with the water storage cavity 102, and the output end of the water extraction pump 3 is fixedly communicated with the water delivery cavity 302 through a first pipeline 301.

[0026] Rotating bases 2 are rotatably connected to both inner walls of the cleaning cavity 101, a motor 205 is fixedly installed on the side wall of the cleaning box 1, the output end of the motor 205 is fixedly connected to one of the rotating bases 2, an electric telescopic rod 201 is fixedly installed on the rotating base 2, a cleaning mesh cylinder 202 is fixedly connected to the output end of the electric telescopic rod 201, a first connecting ring 203 and a second connecting ring 204 are respectively fixedly connected to the two cleaning mesh cylinders 202, and a limiting component for limiting and fixing the two cleaning mesh cylinders 202 is arranged on the first connecting ring 203 and the second connecting ring 204.

[0027] The limiting component includes a bolt fixedly connected to the first connecting ring 203, and a plugging hole matched with the bolt is provided on the second connecting ring 204.

[0028] During use, first send the vacuum oil pump to be cleaned into the cleaning box 1 and place it between the two cleaning mesh cylinders 202. Then start the electric telescopic rod 201. The electric telescopic rod 201 pushes the two cleaning mesh cylinders 202 to move towards each other until the two cleaning mesh cylinders 202 abut against each other, thus forming a cleaning mesh cage. Then start the water pump 3. The water pump 3 sucks the water in the water storage cavity 102 and transports it into the water delivery cavity 302 through the first pipeline 301, and sprays it out through the spray nozzle 303, so that it sprays on the surface of the vacuum oil pump, thereby realizing the cleaning of the impurities on the surface of the vacuum oil pump. At the same time, start the motor 205. The motor 205 drives the rotating base 2 to rotate, and the rotating base 2 drives the cleaning mesh cage to rotate synchronously, so that it can comprehensively clean the surface of the vacuum oil pump, thus improving the cleaning effect of the impurities on the surface of the vacuum oil pump. The cleaned water falls downward and is filtered by the filter screen 103, so that the particulate impurities carried in the water can be filtered out. Then the filtered water falls into the water storage cavity 102, thereby realizing the recycling of the cleaning water, and thus reducing the waste of water resources.

[0029] Embodiment 2:

[0030] Refer to Figure 1 、 Figure 2 、 Figure 4 The mechanical impurity cleaning device for the vacuum oil pump is basically the same as that in Embodiment 1. Further, the driving part includes an impeller 401. The first pipeline 301 is fixedly connected to the side wall of the cleaning box 1, and the impeller 401 is fixedly installed at one end of the reciprocating screw rod 4 passing through the first pipeline 301.

[0031] During the cleaning process of the vacuum oil pump, when the water flow passes through the first pipeline 301, it drives the reciprocating screw rod 4 to rotate by impacting the impeller 401. The reciprocating screw rod 4 drives the T-shaped scraper 402 to move left and right reciprocally on the surface of the filter screen 103, so that the T-shaped scraper 402 can scrape the impurities on the surface of the filter screen 103 out through the sewage discharge groove 405, thereby achieving the purpose of cleaning the filter screen 103. At the same time, start the air suction pump 6. The air suction pump 6 sucks external gas and sprays it into the jet nozzle 602 through the second pipeline 603, thereby realizing the effect of dredging the filter holes of the filter screen 103. At the same time, the connecting plate 601 drives the jet nozzle 602 that continuously jets air in the opposite direction to the filter screen 103 to move synchronously with the T-shaped scraper 402 through the connecting rod 403, so that it can comprehensively dredge the filter holes of the filter screen 103, thereby keeping the filter screen 103 unobstructed, and effectively solving the problem in the prior art that the blockage of the filter holes of the filter screen 103 affects the filtration and collection of the cleaned water;

[0032] It should be noted that the second pipeline 603 is a stretchable and retractable hose, so the second pipeline 603 will not interfere with the left and right reciprocating movement of the T-shaped scraper 402 and the connecting plate 601;

[0033] An activated carbon filter screen (not shown in the figure) is provided inside the input end of the suction pump 6. When the external gas passes through the input end of the suction pump 6, by contacting the activated carbon filter screen, due to the developed void structure and rich microporous tissue inside the activated carbon, these microporous tissues have a powerful adsorption force field. When the gas contacts the activated carbon, the powerful adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas.

[0034] Embodiment 3:

[0035] Refer to Figure 1 , the mechanical impurity cleaning device of the vacuum oil pump is basically the same as that of Embodiment 1. Further, wind instrument sleeves 5 are fixedly connected to both inner walls of the cleaning chamber 101. One ends of the two wind instrument sleeves 5 away from the inner walls of the cleaning chamber 101 are respectively fixedly connected to both sides of the T-shaped scraper 402; the wind instrument sleeves 5 can protect the reciprocating lead screw 4 located in the cleaning chamber 101, preventing the particulate impurities removed from falling into the thread grooves of the reciprocating lead screw 4 and affecting the reciprocating lead screw 4 to drive the T-shaped scraper 402 to move.

[0036] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
