The working principle is as follows: when the device is used, the slurry inlet 101 is aligned with a slurry pipeline, the slurry pipeline enters the device through the slurry inlet 101, the partition plate 107 does not partition the slurry inlet 101 from the tank 102 at the moment, so the slurry can enter the tank 102, after the slurry enters the tank 102, the slurry is firstly filtered through the coarse filtering component 80 in the tank 102, large impurities in the slurry are blocked on the upper filtering plate 801, then the filtered slurry enters one end, close to the left base 104, of the tank 102, when the storage height of the slurry in the tank 102 reaches the height in the middle filtering pipe 106, the fine filtering net on the middle filtering pipe 106 can block large-particle soil in the slurry, the large-particle soil cannot enter the middle filtering pipe 106, after the slurry which is filtered again passes through the fine filtering net of the middle filtering pipe 106, the driving motor 108 is started, the driving motor 108 drives the water turbine 109 to rotate, the water turbine 109 drives the slurry to pass through the slurry outlet 103, and the slurry flows out of the slurry outlet 103.

At this time, slurry in the tank body 102 also flows into the metering shell 301 through the metering connecting pipe 304, when the height of the slurry in the tank body 102 gradually rises, the slurry can synchronously rise in the metering shell 301, when the slurry rises, the metering float 302 can be driven to slide in the metering shell 301 in a direction away from the metering connecting pipe 304, when the slurry in the tank body 102 is stored to a preset height, the floating convex block on the metering float 302 can extrude the metering trigger 303 to enable the metering trigger 303 to slide on the metering shell 301, then the metering trigger 303 triggers, then the metering trigger 303 enables the trigger cylinder to start, the trigger cylinder drives the sliding clamping shaft 209 to slide in a direction close to the valve screw rod 110, so that the convex groove on the sliding clamping shaft 209 is matched with the clutch groove, then the driving motor 108 drives the displacement sliding shaft 202 to rotate through the first belt 201, the displacement sliding shaft 202 drives the sliding clamping shaft 209 to rotate through the second belt 208, at this time, the sliding clamping shaft 209 is matched with the valve screw rod 110, the valve 110 drives the partition plate 107 to move towards the direction away from the partition plate 107, so that the slurry inlet of the slurry in the tank body 102 can be conveniently installed in a cleaning device for cleaning.

After the partition board 107 closes the tank 102, the sliding cylinder 204 is activated, the sliding cylinder 204 drives the sliding shaft 202 to slide away from the sliding shaft 209, so that the initial gear on the sliding shaft 202 is engaged with the first gear 203, then the initial gear drives the first gear 203 to rotate, the first gear 203 drives the intermediate shaft 206 and the second gear 205 to rotate, then the second gear 205 drives the pressing gear 401 to rotate on the right base 105, while the pressing gear 401 rotates, the pressing gear 401 drives the projecting ramp to rotate around the axis of the pressing gear 401, while the projecting ramp moves, since the upper filter board 801 has large impurities or particles left by the filtered slurry, the upper filter board 801 cannot move along with the projecting ramp because of the pre-pressing force of the spring of the upper filter board 801, the upper filter board 801 gradually slides away from the axis of the pressing gear 401 along with the movement of the projecting ramp, and when the lower filter board 802 slides, the upper filter board 801 is not sliding, so that the filter holes on the upper filter board 801 and the lower filter board 802 are misaligned, so that the upper filter board 801 and the lower filter board assembly 802 rotates with the projecting gear 401, when the lower filter board 802 rotates, the upper filter board 401 and the lower filter board 802 rotates, the filtering gear 401 and the filtering gear 802, the upper filter board assembly 802 rotates together with the projecting gear 802, the filtering gear 401, when the filtering gear 802, the filtering gear 401 and the filtering screen board 802 rotates, the filtering screen board 802, the filtering assembly 802 rotates, the upper filter board 801 rotates, the upper filter board 401 and the filtering gear 401, the filtering screen board 802, the filtering assembly 802, the upper filter board 401 is misaligned, the filtering screen board 802, the filtering assembly 802, the upper filter board 401, the filtering screen board 401, the filtering assembly 802 rotates, therefore, the upper filter plate 801 and the lower filter plate 802 scrape impurities on the surface of the inner wall of one side of the tank 102, and the effect of cleaning the inner wall of one side of the tank 102 is also achieved.

At this time, the coarse filter assemblies 80 symmetrically arranged on the main stop block 406 also rotate along with the rotation of the extrusion gear 401, so that the upper filter plate 801 and the lower filter plate 802 form a surface without filter holes, while the coarse filter assemblies 80 on the semicircular stop block 404 rotate, the semicircular stop block 404 also rotates around the axis of the extrusion gear 401, at this time, the semicircular stop block 404 slides on the central stop block 405 and the main stop block 406, and after the extrusion gear 401 rotates to a predetermined angle, the square protrusion 402 also contacts with the upper baffle 408, so as to drive the upper baffle 408 to rotate around the axis of the extrusion gear 401, so that after the extrusion gear 401 continues to rotate, the upper baffle 408 stretches the upper spring 409, and after the upper baffle 408 rotates to a predetermined position, the upper baffle 408 contacts with the sludge outlet baffle 413, at this time, the upper baffle 408 continues to rotate and extrudes the sludge outlet baffle 413, the sludge outlet baffle 413 is also rotated around the axis of the extrusion gear 401, so that the sludge outlet baffle 413 also opens the channel of the sludge outlet 412, the sludge settled in the tank 102 or the material particles which do not pass through the middle filter pipe 106 flow out of the tank 102 from the sludge outlet 412, a collecting device can be arranged outside the sludge outlet baffle 413 for collecting the filtered impurities, when the upper baffle 408 driven by the extrusion gear 401 rotates to a predetermined angle, the upper spring 409 is stretched to the limit, the tank 102 is driven by the upper spring 409 to rotate on the left base 104, and the purpose of the rotation is to make the coarse filter assembly 80 on the semicircular block 404 and the coarse filter assembly 80 on the main block 406 form an included angle, and make the large impurities or particles between the included angle rotate along with the rotation of the tank 102, so that the large impurities or particles can be caused by gravity, fall onto the extrusion gear 401, and then collect large impurities or particles through the extrusion gear 401 and the collecting plate 411, so that the process of cleaning the impurities on the upper filter plate 801 can be achieved.

When the extrusion gear 401 rotates, the extrusion gear 401 can also drive the third gear 207 to rotate, the third gear 207 drives the cleaning shaft 511 to rotate, the cleaning shaft 511 can also drive the scraper screw 503 to rotate through the third belt 502, so that the scraper screw 503 drives the arc-shaped scraper 501, the arc-shaped scraper 501 moves towards the direction far away from the fourth belt 504, and the arc-shaped scraper 501 slides on the inner wall of one side of the tank body 102, so that the arc-shaped scraper 501 cleans sediments on the inner wall of the side, and some settled mud or particles are pushed towards the direction of the sludge outlet part 412, so that the arc-shaped scraper 501 can achieve the cleaning effect.

When the scraper screw 503 rotates, the scraper screw 503 also drives the central screw 505 and the rotating central shaft 506 to rotate through the fourth belt 504, so that the central screw 505 drives the cleaning slider 508 to slide in a direction away from the central baffle 507, the cleaning slider 508 also drives the fixed large gear 512 and the triangular bracket 510 to slide on the rotating central shaft 506 at the same time of sliding on the rotating central shaft 506, the rotating central shaft 510 also drives the triangular bracket 510 to rotate, the triangular bracket 510 rotates to drive the cleaning small gear 509 to mesh on the fixed large gear 512, so that the cleaning small gear 509 drives the cleaning slider 508 to rotate, the cleaning slider 508 also rotates around the axis of the rotating central shaft 506 while rotating, and the cleaning slider 508 also slides in a direction away from the central baffle 507 to clean the inner wall of the whole central filter pipe 106, so that the mud on the central filter pipe 106 is washed, and the washed mud flows out through the central filter screen on the filter pipe 106, and then is squeezed into the sludge outlet 412 through the scraper 501 and flows out of the device.

It should be noted that when the device is cleaning, the tank 102 is filled with slurry, and the reason why the tank 102 is filled is that the middle filter tube 106 or the upper filter plate 801 and the lower filter plate 802 are blocked, so that the slurry is blocked after entering the device and cannot flow out of the device, so the device only performs the above operation.
