[0027] During specific use, through the setting of the filter screen 5, the filter plate 7, the first motor 8, the first screw rod 9, the first slider 10 and the brush plate 11, the negative pressure machine 2 is fixed on one side of the upper surface of the shell 1. When the negative pressure machine 2 is started, the gas inside the shell 1 can be extracted, thereby reducing the air pressure inside the shell 1, which is convenient for extracting sewage through the suction pipe 3. The funnel 4 is fixed at one end of the suction pipe 3, which can expand the suction force and increase the extraction range. The filter screen 5 performs preliminary filtration on the extracted sewage to prevent large particulate impurities from entering the interior of the device and reduce the influence of impurities such as scum on the device and the pipeline. The filter plate 7 is fixed at the edge of the upper surface of the fixed plate 6, and can perform secondary filtration on the sewage entering the device, thereby increasing the effect of subsequent sewage treatment. The first motor 8 drives the first screw rod 9 to rotate, so that the first slider 10 on its outer surface drives the brush plate 11 to reciprocate up and down on the outer surface of the filter plate 7, thereby removing impurities inside the mesh of the filter plate 7, maintaining the performance of the filter plate 7, and enhancing the practicality and use effect of the device.

[0028] In this embodiment, both sides of the upper surface of the fixing plate 6 are fixedly connected with the holders 12 , and the interior of the holders 12 is clamped with the adsorption plate 13 .

[0029] During specific use, through the setting of the adsorption plate 13, the three groups of adsorption plates 13 are clamped in the inside of the three groups of clamping seats 12, which are easy to install and disassemble, easy to replace and clean, and prevent the adsorption effect from deteriorating after repeated use. The three groups of adsorption plates 13 adsorb and filter the sewage.

[0030] In this embodiment, a drain pipe 14 is fixedly connected to the middle of the right side of the shell 1 , and a control valve 15 is fixedly connected to the outer surface of the drain pipe 14 .

[0031] During specific use, by setting the control valve 15, the control valve 15 can be used to control the switch state of the drain pipe 14 to discharge the sewage after separation and filtration.

[0032] In this embodiment, a second motor 16 is fixedly connected to the middle of the inner side of the housing 1 , a second screw rod 17 is fixedly connected to the output end of the second motor 16 , and a second slider 18 is threadedly connected to the outer surface of the second screw rod 17 .

[0033] During specific use, through the arrangement of the second screw rod 17 , the second motor 16 drives the second screw rod 17 to rotate, so that the second slider 18 on the outer surface thereof drives the adjustment plate 19 to move, and the adjustment is convenient.

[0034] In this embodiment, an adjustment plate 19 is fixedly connected to the upper surface of the second sliding block 18 .

[0035] During specific use, through the setting of the adjusting plate 19, the adjusting plate 19 supports the impurities blocked by the filter plate 7 when it is not opened. When the adjusting plate 19 moves under the action of the second screw 17, the impurities on its surface will fall into the interior of the collecting box 22, thereby improving the cleaning effect of sewage impurities and increasing the practicability of the device.

[0036] In this embodiment, baffles 20 are fixedly connected to both sides of the inner side surface of the housing 1 close to the adjustment plate 19 , and guide blocks 21 are fixedly connected to the upper surface of the baffle 20 .

[0037] During specific use, through the setting of the guide block 21, two sets of baffles 20 are fixed on both sides of the inner side of the shell 1 to block the top of the second screw rod 17 to prevent impurities from contacting the second screw rod 17 and ensure the smooth operation of the second screw rod 17. The guide block 21 guides the blocked impurities so that they can better fall into the interior of the collection box 22.

[0038] In this embodiment, a collecting box 22 is movably connected to the bottom of the inner side of the shell 1 , and a diverter plate 23 is fixedly connected to the inner bottom wall of the collecting box 22 .

[0039] During specific use, through the setting of the collecting box 22, when the adjusting plate 19 is opened, the impurities in the internal resistance of the shell 1 will enter the collecting box 22 for collection, making it more convenient to clean the impurities. The diverter plate 23 is an inclined plate structure, which can avoid the collected impurities from piling up and play a diversion role.

[0040] In this embodiment, universal wheels 24 are fixedly connected to the four corners of the lower surface of the collection box 22, and both sides of the front side of the housing 1 are rotatably connected to limit plates 25.

[0041] During specific use, through the setting of universal wheels 24, four groups of universal wheels 24 are fixed on the lower surface of the collection box 22, making it more convenient to pull out the collection box 22, and increasing the flexibility of the movement of the collection box 22. The limiting plate 25 limits the collection box 22 when it is inside the shell 1, avoiding the collection box 22 from moving randomly when the device is running, thereby ensuring stability during use.

[0042] Working principle: During use, the negative pressure machine 2 is started to extract the gas inside the shell 1, and the sewage is extracted through the suction pipe 3. The funnel 4 increases the extraction range. The filter screen 5 performs preliminary filtration on the extracted sewage to prevent large particles of impurities from entering the interior of the device. The filter plate 7 performs secondary filtration on the sewage entering the interior of the device, thereby increasing the effect of subsequent sewage treatment. The first motor 8 drives the first screw rod 9 to rotate, so that the first slider 10 drives the brush plate 11 to reciprocate up and down on the outer surface of the filter plate 7 to remove impurities inside the mesh of the filter plate 7 and maintain the performance of the filter plate 7. The three groups of adsorption plates 13 are clamped inside the three groups of clamping seats 12 to remove the impurities. The water is subjected to adsorption filtration treatment, and the control valve 15 can be used to control the switching state of the drain pipe 14 to discharge the separated and filtered sewage. The adjusting plate 19 supports the impurities blocked by the filter plate 7 when it is not opened. When the impurities need to be cleaned, the second motor 16 drives the second screw rod 17 to rotate, so that the second slider 18 drives the adjusting plate 19 to move. The impurities on the surface of the adjusting plate 19 will fall into the interior of the collecting box 22, making it easier to clean the impurities. The diverter plate 23 is an inclined plate structure, which can prevent the collected impurities from piling up. The four sets of universal wheels 24 make it easier to pull the collecting box 22, thereby increasing the flexibility of the movement of the collecting box 22.
