[0032] In this embodiment: in this device, the sieve bucket 210 is a box body with a through hole, and one side is connected to the outside world, so as to separate and throw out the solids inside the sieve bucket 210. When the user uses the device, the user can inject the sewage that needs to be separated into solid and liquid into the water storage tank 211. After injecting a certain amount, the user can start the motor 22, and the motor 22 drives the first pulley 23 to rotate, and then drives the second pulley 24 to rotate through the belt. During the rotation of the second pulley 24, it will also drive the first rotating arm 26 fixedly connected to the connecting rod 25 to rotate, and the rotation direction is close to the sieve bucket 210, and the connecting rod 25 is rotatably connected to the mounting plate 21. When the first rotating arm 26 rotates, it will rotate through the first rotating arm 26 rotating connection The second rotating arm 27 connected thereto moves in the vertical direction, and at the same time pulls the rotating member 28 and the slider 213 at the end of the rotating member 28 to slide upward inside the chute 212. The chute 212 is composed of a vertical through slot and an arc-shaped through slot. The rotating member 28 drives the sieve bucket 210 to move vertically upward through the rotating rod 29. At this time, the solids in the sewage inside the water tank 211 will remain inside the sieve bucket 210 and rise with the sieve bucket 210. At the same time, the spring 215 continuously releases elastic potential energy to push the top block 214 to rise. The inclined structure of the top block 214 will continue to press against the bottom end of the rotating member 28, so that the rotating member 28 always has an outward rotational force. When the first rotating arm 26 rotates to the topmost position, the slider 213 presses against the chute 2 At this time, the second pulley 24 continues to rotate, driving the first rotating arm 26 to start moving downward, thereby connecting the rotating member 28 and the second rotating arm 27 to the upper surface of the mounting base 1, thereby achieving the separation of solids. At this time, the second pulley 24 continues to rotate, driving the first rotating arm 26 to start moving downward, thereby connecting the rotating member 28 and the second rotating arm 27 to the upper surface of the mounting base 1, thereby achieving the separation of solids. At this time, the second pulley 24 continues to rotate, driving the first rotating arm 26 to start moving downward, thereby connecting the rotating member 28 and the second rotating arm 27 to the upper surface of the mounting base 1, thereby achieving the separation of solids. The connection point of the two rotating arms 27 is pushed out from the arc groove of the slide 212. As the second pulley 24 continues to rotate, the first rotating arm 26 and the second rotating arm 27 are pushed to the vertical state again. At this time, the sieve bucket 210 also enters the water tank 211 again to extract the liquid inside the water tank 211. The user can inject the sewage that needs solid-liquid separation into the water tank 211 again and repeat the above operation. The solids in the sewage can be separated by the rotating part 28 and the sieve bucket 210. The solids and liquids in the sewage are separated by filtering, which can significantly improve the sewage treatment efficiency. There is no need for manual participation in cleaning work. The solid dirt thrown out by the sieve bucket 210 can be quickly removed from the system, ensuring the continuous and efficient operation of the treatment equipment.Prevent solid dirt from clogging the screen bucket 210. The separated liquid can be further processed or reused, while the solid dirt is convenient for subsequent treatment or disposal. The solid dirt is quickly and effectively separated and thrown out, making the treatment process smoother and shortening the treatment cycle.

[0033] Going further:

[0034] In an optional embodiment, the anti-swing plate 216 is an arc-shaped structure, and a plurality of through holes are opened on one side of the anti-swing plate 216.

[0035] In this embodiment, the arc-shaped anti-swing plate 216 can prevent solid dirt from colliding with the anti-swing plate 216 and being ejected. The arc-shaped anti-swing plate 216 can make the solid dirt slide down the surface of the anti-swing plate 216, and can absorb part of the impact of the solid dirt on the anti-swing plate 216. At the same time, the through holes opened in the anti-swing plate 216 can further filter out the moisture of the solid dirt.

[0036] Going further:

[0037] In an optional embodiment, a plurality of wheels 217 are mounted on the lower surface of the mounting base 1 .

[0038] In this embodiment: a plurality of wheels 217 are installed on the lower surface of the mounting base 1. Through the wheels 217, the device can move by itself, reducing the need for manual handling and operation, which not only reduces labor costs, but also reduces the labor intensity of the staff. After the wheels 217 are installed, the device can be easily moved to the designated maintenance and inspection area, reducing the difficulty and cost of maintenance and inspection. The device with the wheels 217 installed can be quickly moved to the sewage that needs to be treated, reducing waiting and preparation time.

[0039] Working principle: In this device, the sieve bucket 210 is a box with a through hole, and one side is connected to the outside world, so as to separate and throw out the solids inside the sieve bucket 210. When the user uses the device, the user can inject the sewage that needs to be separated into solids and liquids into the water tank 211. After injecting a certain amount, the user can start the motor 22, and the motor 22 drives the first pulley 23 to rotate, and then drives the second pulley 24 to rotate through the belt. During the rotation of the second pulley 24, it will also drive the first rotating arm 26 fixedly connected to the connecting rod 25 to rotate, and the rotation direction is close to the sieve bucket 210, and the connecting rod 25 is rotatably connected to the mounting plate 21. When the first rotating arm 26 rotates, it will rotate through the first rotating arm 26 The second rotating arm 27 moves in the vertical direction, and at the same time pulls the rotating member 28 and the slider 213 at the end of the rotating member 28 to slide upward inside the slide 212. The slide 212 is composed of a vertical through slot and an arc-shaped through slot. The rotating member 28 drives the screen bucket 210 to move vertically upward through the rotating rod 29. At this time, the solids in the sewage inside the water tank 211 will remain inside the screen bucket 210 and rise with the screen bucket 210. At the same time, the spring 215 continues to release elastic potential energy to push the top block 214 to rise. The inclined structure of the top block 214 will continue to press against the bottom end of the rotating member 28, so that the rotating member 28 always has an outward rotational force. When the first rotating arm 26 rotates to the topmost position, the slider 213 presses against the slide 21 2, and at the same time, under the push of the top block 214, the connection between the rotating member 28 and the second rotating arm 27 rotates into the arc groove of the slide 212 to its top. At this time, the rotating member 28 rotates ninety degrees, and at the same time drives the sieve bucket 210 outside the end of the rotating rod 29 to rotate ninety degrees, so that the opening of the sieve bucket 210 faces the rear side, and through the elastic connection between the rotating member 28 and the rotating rod 29, the sieve bucket 210 vibrates to a certain extent, so that the fixed part inside the sieve bucket 210 is thrown backward and falls into the upper surface of one end of the mounting base 1 under the obstruction of the anti-throwing plate 216, thereby achieving solid separation. At this time, the second pulley 24 continues to rotate, driving the first rotating arm 26 to start moving downward, thereby connecting the rotating member 28 and the second rotating arm 27 to the first rotating arm 27. The connection point of the two rotating arms 27 is pushed out from the arc groove of the slide 212. As the second pulley 24 continues to rotate, the first rotating arm 26 and the second rotating arm 27 are pushed to the vertical state again. At this time, the sieve bucket 210 also enters the water tank 211 again to extract the liquid inside the water tank 211. The user can inject the sewage that needs solid-liquid separation into the water tank 211 again and repeat the above operation. The solids in the sewage can be separated by the rotating part 28 and the sieve bucket 210. The solids and liquids in the sewage are separated by filtering, which can significantly improve the sewage treatment efficiency. There is no need for manual participation in cleaning work. The solid dirt thrown out by the sieve bucket 210 can be quickly removed from the system, ensuring the continuous and efficient operation of the treatment equipment.Prevent solid dirt from clogging the screen bucket 210. The separated liquid can be further processed or reused, while the solid dirt is convenient for subsequent processing or disposal. The solid dirt is quickly and effectively separated and thrown out, making the processing process smoother and shortening the processing cycle. At the same time, the arc-shaped anti-swing plate 216 can prevent solid dirt from colliding with the anti-swing plate 216 and being ejected. The arc-shaped anti-swing plate 216 can make the solid dirt slide down the surface of the anti-swing plate 216, and can absorb part of the impact of the solid dirt on the anti-swing plate 216. At the same time, the through holes opened in the anti-swing plate 216 can further screen the moisture of the solid dirt. A plurality of wheels 217 are installed on the lower surface of the mounting base 1. Through the wheels 217, the device can move by itself, reducing the need for manual handling and operation, which not only reduces labor costs, but also reduces the labor intensity of the staff. After the wheels 217 are installed, the device can be easily moved to the designated maintenance and inspection area, reducing the difficulty and cost of maintenance and inspection.
