One end of the filter belt 23 abuts against the inner wall of the embedding groove 11 to reduce the outflow of debris through the gap between the filter belt 23 and the inside of the filter bin 1, thereby maintaining the filtering effect of the device; the first motor 22 is installed in the filter bin 1 and connected to one of the conveying rollers 21. The first motor 22 is started, so that the filter belt 23 can be transported in the filter bin 1.

[0031] In other embodiments, anti-skid grooves are provided on the surface of the filter belt 23, and the anti-skid grooves can increase the friction between the debris and the surface of the filter belt 23, so as to facilitate the transfer of the debris.

[0032] Reference Figure 2 and Figure 4 The cleaning structure 3 includes a first cleaning component 4 and a second cleaning component 5. The first cleaning component 4 is used to clean the surface of the filter belt 23, and the second cleaning component 5 cleans the inner wall of the filter belt 23. The first cleaning component 4 includes a rotating disk 41, a guide plate 42, a second motor and a push-out component 44. A cleaning box 12 is installed on the outer wall of the filter bin 1. The cleaning box 12 has a cleaning cavity 13. The filter bin 1 is provided with a transfer hole 14 connected to the cleaning cavity 13; the guide plate 42 is fixed to the inner wall of the transfer hole 14, and one end of the guide plate 42 away from the cleaning cavity 13 is connected to the surface of the filter belt 23.

[0033] Reference Figure 4 and Figure 5 The rotating disk 41 includes a rotating ring 411, two connecting rings 412 and a plurality of partition plates 413. The rotating ring 411 is provided with a rotating portion 414, which is rotatably mounted on the inner wall of the cleaning chamber 13. The second motor is mounted on the cleaning box 12 and connected to the connecting portion. The two connecting rings 412 are respectively mounted on opposite sides of the outer peripheral wall of the rotating ring 411. All the partition plates 413 are mounted between the two partition plates 413 and are circumferentially spaced along the outer peripheral wall of the rotating ring 411. A transfer groove 415 for placing garbage is formed between the rotating ring 411 and two adjacent partition plates 413.

[0034] Reference Figure 4In this embodiment, a plurality of water outlet holes 416 are provided on the inner wall of the transfer groove 415, and all the water outlet holes 416 are provided on the rotating ring 411. After the garbage enters the transfer groove 415, the rotating ring 411 rotates toward the side away from the guide plate 42 under the drive of the second motor, and the sludge in the debris flows out into the cleaning chamber 13 through the water outlet holes 416, and then flows out into the filter chamber. At this time, the debris is pushed out from the transfer groove 415 into the lower cleaning box 12, thereby reducing the situation where the debris entering the cleaning box 12 is accompanied by sludge, and reducing the possibility of sludge being brought out to the outside during the centralized treatment of the debris in the first cleaning box 12.

[0035] The upper surface of the cleaning chamber 13 is configured as an arc surface, which abuts against the two connecting rings 412 to reduce the possibility that debris flies out of the transfer groove 415 and enters the cleaning chamber 13 during the rotation of the rotating ring 411 .

[0036] Reference Figure 6 and Figure 7 There are multiple groups of ejection components 44, and each ejection component 44 is installed in each transfer groove 415 respectively; the ejection component 44 includes an ejection plate 441 and an ejection member 442, and the ejection plate 441 is movably installed in the transfer groove 415; the inner wall of the transfer groove 415 is provided with a collecting hole 15 connected to the first collecting box 61, and during the rotation of the rotating ring 411, each ejection hole 417 is arranged opposite to the collecting hole 15 one by one.

[0037] Reference Figure 4 and Figure 6 The cleaning box 12 is provided with a rotating groove 43 connected to the cleaning chamber 13; the ejection member 442 includes a reset spring 444, a movable rod 443 and a first guide block 445. A movable hole 418 is provided on the side of the transfer groove 415 away from the collecting hole 15. The movable rod 443 is fixed to the ejection plate 441. The movable rod 443 passes through the ejection hole 417 and enters the rotating groove 43; the first guide block 445 is fixed to one end of the movable rod 443 away from the ejection plate 441, the reset spring 444 is sleeved on the outer wall of the movable rod 443, and the two ends of the reset spring 444 are respectively fixed to the first guide block 445 and the outer wall of the rotating ring 411, and the elastic force of the reset spring 444 drives the ejection plate 441 to abut against the side of the transfer groove 415 close to the movable hole 418 under normal conditions.

[0038] Reference Figure 4 and Figure 8 The two opposite sides of the first guide block 445 are respectively defined as a guide surface 446 and a positioning surface, and the distance between the guide surface 446 and the positioning surface gradually decreases from the side far away from the rotating ring 411 to the side close to the rotating ring 411; a support rod 47 is fixed to the inner wall of the rotating groove 43, and a second guide block 48 is provided on the side of the support rod 47 close to the rotating ring 411. The second guide block 48 is arc-shaped and is located on the moving path of the first guide block 445.

[0039] During the rotation of the rotating ring 411, the guide surface 446 of the first guide block 445 abuts against the second guide block 48, so that the first guide block 445 moves toward the side of the rotating ring 411 under the guidance of the guide surface 446, and then the push-out plate 441 moves toward the side of the ejection hole 417; when the collecting hole 15 and the ejection hole 417 are arranged opposite to each other, the side of the first guide block 445 away from the movable rod 443 abuts against the second guide block 48, and the debris is pushed out from the transfer groove 415 into the first collecting box 61; and after the first guide block 445 completely passes through the second guide block 48 under the rotation of the rotating ring 411, the first guide block 445 returns to its original state under the elastic force of the reset spring 444, and the push-out plate 441 abuts against the side of the transfer groove 415 close to the movable hole 418 again, so that the debris can enter the transfer groove 415 in time.

[0040] Moreover, during the process of the second guide block 48 abutting against the first guide block 445, the ejection plate 441 can squeeze the debris in the transfer groove 415, thereby squeezing the water in the debris into the cleaning chamber 13, further improving the convenience of cleaning the debris in the first collection box 61, and reducing the possibility of water overflowing to the outside during the process of handling the debris in the first collection box 61.

[0041] Reference Fig. 9 The inner wall of the filter bin 1 is provided with a collecting port 16 connected to the second collecting box 62. In this embodiment, the second collecting box 62 is provided with a drain hole. When the sludge in the filter bin 1 enters the second collecting box 62 through the collecting port 16, it can flow out through the drain hole, thereby reducing the situation where the sludge flows out to the outside when cleaning the second collecting box 62.

[0042] The second cleaning component 5 includes a cleaning plate, which is fixed to the inner wall of the collecting bin and is located between the two conveying rollers 21, and is used to pour the mud and sand inside the filter belt 23 into the second collecting box 62; in this embodiment, the cleaning plate is in contact with the side wall of one of the conveying rollers 21, and after the mud and sand enter the filter belt 23 through the filter hole 25, the mud and sand are reduced from entering between the cleaning plate and the conveying roller 21, thereby improving the cleaning effect of the cleaning plate on the mud and sand inside the filter belt 23.

[0043] The side of the cleaning plate away from the conveying roller 21 abutting against the cleaning plate is set as a cleaning surface 51, and the distance between the cleaning surface 51 and the conveying roller 21 gradually decreases from the end away from the second collecting box 62 to the end close to the second collecting box 62. During the conveying process of the filter belt 23, the cleaning plate abuts against the inner wall of the filter belt 23, and blocks the silt on the inner wall of the filter belt 23 to the side of the cleaning surface 51. The silt is guided by the cleaning surface 51 and then enters the second collecting box 62, thereby playing the role of secondary filtration of the diluted sludge and improving the filtration effect.

[0044] A cleaning nozzle is provided at the bottom of the cleaning plate, and one end of the cleaning nozzle is connected to an external water supply device; after the filter belt 23 enters the bottom of the cleaning plate, the cleaning nozzle sprays water to flush the filter hole 25, thereby reducing the blockage of the filter hole 25 and maintaining the filtering effect of the filter belt 23.

[0045] The implementation principle of the embodiment of the present application is: When filtering the diluted sludge, pour the diluted sludge into the filter bin 1; the construction waste and sand are blocked by the filter holes of the filter belt 23 and retained on the surface and inner wall of the filter belt 23, thereby playing a role of secondary filtration and improving the filtering effect of the diluted sludge; the filter belt 23 is transported in the filter bin 1, so that the debris can be transported on the filter belt 23 to change its position in the filter bin 1, so that the guide plate 42 can scrape off the debris on the surface of the filter belt 23, and the cleaning plate guides the mud and sand on the inner wall of the filter belt 23 to the second collection box 62, thereby playing the role of cleaning the debris in the filter bin 1 during the operation, thereby improving the work efficiency.
