An inner cylinder 11 is connected, and the inner wall of the inner cylinder 11 is located at the bottom and is connected to a filter plate 17 by bolts. A guide plate 19 is connected to the inner wall of one side of the liquid inlet pipe 9 by a hinge, and the guide plate 19 is tilted. A spring 20 is connected between one side of the guide plate 19 and the inner wall of the liquid inlet pipe 9 by bolts. A rotating mechanism is provided on the inner wall of the liquid inlet pipe 9, and an extrusion mechanism 13 is provided between the two sides of the rotating mechanism and the inner cylinder 11. The rotating mechanism and the extrusion mechanism 13 form a match, which can quickly and effectively collect and process the waste liquid, thereby improving the collection efficiency of the waste liquid, and preventing part of the waste liquid from adhering to the solid impurities and being difficult to discharge, thereby affecting the collection of the waste liquid.

[0027] On the basis of the above, a sealing groove 14 is opened on the top of the collecting tank 1 , and a sealing ring 15 is inserted into the inner wall of the sealing groove 14 , and the top of the sealing ring 15 is welded to the bottom of the tank cover 4 .

[0028] On the basis of the above, the rotating mechanism is composed of a rotating shaft 21, a support sleeve 22 and a plurality of rotating blades 23, and the two ends of the rotating shaft 21 are rotatably connected to the inner wall of the liquid inlet pipe 9 through bearings, the support sleeve 22 is fixedly sleeved on the outer wall of the rotating shaft 21, and the plurality of rotating blades 23 are fixed on the circumferential outer wall of the support sleeve 22 at equal distances.

[0029] On the basis of the above, the extrusion mechanism 13 includes two shafts 25, two sleeves 27, two push rods 30 and two extrusion plates 28, and one end of the two shafts 25 is welded to the rotating shaft 21, and the outer walls of the two shafts 25 are provided with protrusions 26, the two protrusions 26 are U-shaped, and the protrusion positions of the two protrusions 26 are opposite. The two sleeves 27 are rotatably sleeved on the outer walls of the two protrusions 26, and the two ends of the push rod 30 are respectively connected to the bottom of the sleeve 27 and the top of the extrusion plate 28 by hinges. The shape of the two extrusion plates 28 is semi-annular, and the top of the two extrusion plates 28 is set as an inclined surface. The shaft 25 will rotate synchronously with the rotation of the rotating shaft 21, and the protrusion 26 will rotate synchronously with the rotation of the shaft 25. At this time, the push rod 30 will rotate on the protrusion Under the action of 26 and the shaft sleeve 27, the squeezing plate 28 is driven to move up and down reciprocatingly, so that the waste liquid remaining on the solid impurities can be squeezed out through the squeezing plate 28 to facilitate the collection of the waste liquid. Since the protrusion directions of the two protrusions 26 are opposite, when one of the squeezing plates 28 moves downward, the other squeezing plate 28 moves upward. Therefore, when the squeezing plate 28 squeezes the impurities, the waste liquid will be discharged through the other side of the filter plate 17. Therefore, the collection efficiency of the waste liquid will not be affected by the obstruction of the squeezing plate 28. On the contrary, the cooperation between the two squeezing plates 28 can quickly and effectively collect and process the waste liquid, thereby improving the collection efficiency of the waste liquid and preventing part of the waste liquid from adhering to the solid impurities and being difficult to discharge, thereby affecting the collection of the waste liquid.

[0030] On the basis of the above, the top of the filter plate 17 is connected with a guide block 24 by bolts, and the guide block 24 is in a conical shape.

[0031] On the basis of the above, a plurality of slide grooves 12 are opened on the inner wall of the inner cylinder 11 , and a slider 29 is slidably connected to the inner wall of the slide groove 12 , and one side of the slider 29 is welded to the extrusion plate 28 .

[0033] On the basis of the above, the anti-blocking mechanism 31 is composed of a connecting shaft 34, an anti-blocking plate 32 and a plurality of thorns 33, and the two ends of the connecting shaft 34 are respectively connected to the bottom of the slider 29 and the top of the anti-blocking plate 32 by bolts, and the plurality of thorns 33 are fixed at the top of the anti-blocking plate 32 at equal distances. A sliding opening 18 is provided at the bottom of the slide groove 12, and the sliding opening 18 is slidably connected to the connecting shaft 34. The position of the thorns 33 corresponds to the position of the filter holes of the filter plate 17. When the extrusion plate 28 moves upward, the anti-blocking plate 32 will follow the extrusion plate 28 to move upward. The two filter plates 17 move upward synchronously. Since the positions of the filter holes of the needles 33 and the filter plates 17 correspond to each other, when the anti-blocking plate 32 moves upward, the needles 33 will act on the filter holes of the filter plates 17 to push out the impurities blocked in the filter holes, and the pushed-out solids will accumulate on one side under the flushing of the waste liquid, so that it is convenient for the extrusion plate 28 to extrude the impurities, so as to squeeze out the waste liquid inside the impurities. The cooperation between the extrusion mechanism 13 and the anti-blocking mechanism 31 can effectively collect and process the waste liquid, thereby improving the collection effect of the device on the waste liquid.

[0034] In summary, with the aid of the above technical solution of the present invention: when collecting and treating the waste liquid, the waste liquid is transported to the inside of the collection tank 1 through the liquid inlet hopper 6 and the liquid inlet pipe 9. At this time, the guide plate 19 will deflect to one side under the action of the gravity of the waste liquid, and the waste liquid will flow to one side under the action of the guide plate 19. The flowing waste liquid will act on one side of the rotating mechanism. At this time, the rotating blade 23 will drive the rotating shaft 21 to rotate under the action of the waste liquid, and the shaft 25 will rotate synchronously with the rotation of the shaft 21, and the protrusion 26 will rotate synchronously with the rotation of the shaft 25. At this time, the push rod 30 will rotate between the protrusion 26 and the sleeve 27. The squeezing plate 28 is driven to move up and down reciprocatingly under the action of, so that the squeezing plate 28 can squeeze out the waste liquid remaining on the solid impurities, so as to collect the waste liquid. Since the protrusions of the two protrusions 26 are in opposite directions, when one of the squeezing plates 28 moves downward, the other squeezing plate 28 moves upward. Therefore, when the squeezing plate 28 squeezes the impurities, the waste liquid will be discharged through the other side of the filter plate 17. Therefore, the collection efficiency of the waste liquid will not be affected by the obstruction of the squeezing plate 28. On the contrary, the cooperation between the two squeezing plates 28 can quickly and effectively collect the waste liquid. The collection process is carried out to improve the collection efficiency of the waste liquid, and to prevent part of the waste liquid from adhering to the solid impurities and being difficult to discharge, thereby affecting the collection of the waste liquid. When the impurities are squeezed by the squeezing mechanism 13, when the squeezing plate 28 moves upward, the anti-blocking plate 32 will move up synchronously with the squeezing plate 28. Since the positions of the filter holes of the filter plate 17 correspond to the positions of the needles 33, when the anti-blocking plate 32 moves upward, the needles 33 will act on the filter holes of the filter plate 17 to push out the impurities blocked in the filter holes, and the pushed-out solids will accumulate on one side under the flushing of the waste liquid, so that it is convenient for the squeezing plate 28 to squeeze out the impurities. The extrusion process is performed to squeeze out the waste liquid inside the impurities. The cooperation between the extrusion mechanism 13 and the anti-blocking mechanism 31 can effectively collect and process the waste liquid, thereby improving the device's collection effect on the waste liquid. When the wastewater is collected, the guide plate 19 will be reset under the action of the spring 20, so that one end of the guide plate 19 is tightly attached to the inner wall of the liquid inlet pipe 9, so that the liquid inlet pipe 9 can be sealed through the guide plate 19, so as to seal the interior of the device and prevent the odor of the waste liquid from emitting. When the collected waste liquid needs to be processed, the sealing plug 8 is opened and the waste liquid is discharged through the drain port 7.
