after the impurities sink, the impurities fall into the circulation groove 32 on the extrusion plate 31 through the concave plate 30, and the influence of water flow at the upper part of the concave plate 30 on the impurity precipitation below the concave plate 30 can be reduced due to the existence of the concave plate 30; when the driving motor 5 rotates forwards, the driving shaft 8 rotates forwards, because the driving shaft 8 is connected with the extrusion plate 31 through threads, the extrusion plate 31 moves upwards when the driving shaft 8 rotates, the extrusion plate 31 moves upwards to reduce the pressure below the extrusion plate 31, because the bottom of the pipe opening of the sewage discharge pipe 7 is fixedly connected with the stop block 41, the rotating plate 40 can not be opened outwards, the stop block 34 can move downwards relative to the extrusion plate 31, so that impurities in the circulation groove 32 enter the lower part of the extrusion plate 31, the stop block 34 moves downwards to drive the sliding rod 33 to move downwards, the sliding rod 33 moves downwards to compress the extrusion spring 35, when the driving motor 5 rotates backwards, the driving shaft 8 rotates backwards, the extrusion spring 35 resets at the moment, the stop block 34 moves upwards to reset through the sliding rod 33, the circulation groove 32 is blocked, when the extrusion plate 31 moves downwards to compress the space below the extrusion plate 31, so that the rotating plate 40 is jacked towards the inside of the sewage discharge pipe 7 to discharge the impurities out of the sewage discharge pipe 7, the driving motor 5 rotates forwards and reversely to work alternately, so that impurities precipitated at the bottom are continuously extruded out, and the phenomenon that a large amount of impurities with poor circulation are accumulated to cause the blockage of the sewage discharge pipe 7 is avoided.

The driving shaft 8 drives the first cam 10 to rotate, the first cam 10 intermittently pushes the push rod 11, the push rod 11 pushes the push block 12, the push block 12 slides back and forth on the secondary filter plate 15, impurities accumulated on the secondary filter plate 15 are pushed into the dustbin 3 to be stored, the secondary filter plate 15 is prevented from being blocked due to excessive accumulation of the impurities, the driving shaft 8 also drives the second cam 21 and the third cam 22 to rotate when rotating, the second cam 21 drives the upper cutting plate 23 to reciprocate along a direction perpendicular to a cam groove, the third cam 22 drives the lower cutting plate 24 to reciprocate along a direction perpendicular to the cam groove, because the protruding ends of the second cam 21 and the third cam 22 are opposite in direction, the upper cutting plate 23 and the lower cutting plate 24 do staggered movement in the horizontal direction, the upper cutting plate 23 and the lower cutting plate 24 are provided with the mutually matched blades 25, and therefore, the upper cutting plate 23 and the lower cutting plate 24 can cut floating objects accumulated at the bottom of the primary filter plate 9, then through one-level filter plate 9, second grade filter plate 15 filters aperture and is less than one-level filter plate 9, so the floater can pile up on second grade filter plate 15 when second grade filter plate 15 flows through, then is pushed into dustbin 3 by ejector pad 12, accomplishes to cut the decomposition to bulky floater automatically, then concentrates the collection with the floater, prevents that the floater from blockking up one-level filter plate 9 and second grade filter plate 15 in filtering process.

After more impurities are stored in the dustbin 3, the pressing rod 16 is pushed downwards to push the piston 17 to move downwards, the piston 17 moves downwards to block a through groove in the side wall of the overflow box 2 close to the dustbin 3, meanwhile, the pressing rod 16 drives the driving magnetic block 18 to move downwards, the driven magnetic block 19 also moves downwards, the driven magnetic block 19 drives the sealing plate 20 to move downwards to block the through groove in the side wall of the dustbin 3 close to the overflow box 2, then the dustbin 3 is detached, the impurities in the dustbin 3 are poured out to be treated independently, and the secondary filter plate 15 is prevented from being blocked by the impurities; the piston 17 moves downwards and simultaneously pushes the push block 12 downwards, the upper sliding plate 36 is pushed downwards, the upper sliding plate 36 moves downwards to extrude the vertical plate spring 42, the push sheet 39 made of rubber is compressed, the upper sliding plate 36 can also drive the push rod 11 to move downwards, and one end, close to the first cam 10, of the push rod 11 is not contacted with the first cam 10, so that when the dustbin 3 is taken down, the first cam 10 can still push the push rod 11 and the push block 12 continuously; after the garbage in the garbage can 3 is treated, the garbage can 3 is installed and returned, the pressing rod 16 is lifted upwards, so that the piston 17, the driving magnetic block 18, the driven magnetic block 19 and the sealing plate 20 are driven to reset, the upper sliding plate 36 resets under the action of the vertical plate spring 42, the upper sliding plate 36 drives the push rod 11 to reset upwards, and the push rod 11 is enabled to be abutted against the first cam 10 again;

because the logical groove height that overflow tank 2 is close to 3 one sides of dustbin is higher than the logical groove that overflow tank 2 is close to bin 1 one side, so piston 17 can not stop up the logical groove that overflow tank 2 is close to 3 one sides of dustbin completely after stopping up the logical groove that overflow tank 2 is close to bin 1 one side, so water can also continue to flow into overflow tank 2 from bin 1, then flow out from outlet pipe 6, accomplish and need not closing device when clearing up the impurity in dustbin 3, equipment can continuously run, compare in equipment clearance impurity of stopping, and the work efficiency is increased.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the embodiments and descriptions given above are only illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claims. The scope of the invention is defined by the appended claims and equivalents thereof.
