[0034] As Figures 1-10 shown, a sludge recycling device and utilization method include a shell 1 and a cylinder 6 arranged inside the shell 1. Both ends of the cylinder 6 are in an open state, and the cylinder 6 is coaxially arranged with the shell 1. At both ends of the cylinder 6, an end cover 9 is rotatably arranged. The end cover 9 passes through the shell 1 and is fixedly connected to the shell 1;

[0035] A slide plate 12 is slidably arranged inside the cylinder 6. The slide plate 12 is of a circular structure, and the outer peripheral wall of the slide plate 12 contacts the inner wall of the cylinder 6. During actual use, the slide plate 12 can move relative to the cylinder 6 in the vertical direction. Refer to Figure 2As shown, a plurality of connecting rings 17 are arranged on both the upper and lower sides of the sliding plate 12. The connecting rings 17 are attached to the inner wall of the cylinder body 6, and rubber rings can be fixedly embedded on the outer walls of the connecting rings 17 to increase the friction between the connecting rings 17 and the cylinder body 6. An annular plate 901 is installed on the side of the end cover 9 close to the sliding plate 12. The annular plate 901 is elastically engaged with the end cover 9, enabling the annular plate 901 to move vertically relative to the end cover 9. Specifically, a filtering unit 10 is provided between the side surface of the annular plate 901 close to the sliding plate 12 and the connecting ring 17, between the sliding plate 12 and the adjacent connecting ring 17, and between two adjacent connecting rings 17. The filtering unit 10 adopts a flexible structure. In specific applications, sewage is introduced into the cylinder body 6, and the sewage can be filtered by the filtering unit 10 in the cylinder body 6. A plurality of filtering holes are evenly formed on the side wall of the cylinder body 6, which is conducive to discharging the sewage, causing the sludge to remain inside the cylinder body 6. When the sliding plate 12 moves vertically to one side of the end cover 9, a plurality of filtering units 10 on one side of the sliding plate 12 can be stored in the end cover 9, which is conducive to flushing the stored filtering units 10 later.

[0036] Referring to Figures 2-10 As shown, a diversion pipe 2 is coaxially arranged inside the cylinder body 6. A partition plate 18 is fixedly arranged on the outer peripheral wall of the diversion pipe 2. The number of the partition plates 18 is at least one. The diversion pipe 2 and the partition plate 18 both pass through the sliding plate 12 and are slidably engaged with the sliding plate 12. The sliding plate 12 and the cylinder body 6 are cooperated through a limiting unit, so that when the diversion pipe 2 drives the sliding plate 12 to rotate, the sliding plate 12 can move vertically relative to the cylinder body 6.

[0037] A plurality of spray pipes 11 are installed on both the top surface and the bottom surface of the sliding plate 12. The spray pipes 11 are communicated with the sliding plate 12 and are elastically engaged with the sliding plate 12. When the sliding plate 12 is driven to move to one side of the end cover 9 through the limiting unit, the spray pipes 11 can be inserted into the end cover 9, so as to flush the folded filtering units 10 through the spray pipes 11. A plurality of spray holes 1101 are formed on the outer peripheral wall of the spray pipes 11, and the spray holes 1101 on the spray pipes 11 are arranged opposite to the filtering units 10 stored in the end cover 9.

[0038] The limiting unit includes a limiting block 1201 which is fixedly arranged on the outer peripheral wall of the sliding plate 12. A limiting groove 601 which is slidably matched with the limiting block 1201 is formed on the inner wall of the cylinder body 6. The limiting groove 601 is arranged in a spiral shape. During actual use, although the cylinder body 6 can rotate relative to the end cover 9, the friction force between the cylinder body 6 and the end cover 9 can be increased. In this way, when the diversion pipe 2 drives the sliding plate 12 to rotate, due to the large friction force between the cylinder body 6 and the end cover 9, the cylinder body 6 can be kept stable. At this time, the cooperation between the limiting block 1201 and the limiting groove 601 can drive the sliding plate 12 to move in the vertical direction. When the sliding plate 12 moves to one side of the end cover 9, the limiting block 1201 moves to the end position of the limiting groove 601. At this time, during the process of the diversion pipe 2 driving the sliding plate 12 to rotate, the cooperation between the limiting block 1201 and the limiting groove 601 can drive the cylinder body 6 to rotate synchronously. Through this structure, the sewage can be thrown out, while the sludge is retained in the cylinder body 6 by the filtering unit 10, so as to realize the recycling of the sludge;

[0039] Combined with Figures 2-4 As shown, clamping rings 14 are rotatably connected to the surfaces of the annular plate 901 and the sliding plate 12 facing each other. The filtering unit 10 located between two adjacent connecting rings 17 is fixedly connected to the connecting ring 17. One end of the filtering unit 10 located at the sliding plate 12 is fixedly connected to the connecting ring 17, and the other end is fixedly connected to the clamping ring 14 on the sliding plate 12. Similarly, one end of the filtering unit 10 located at the annular plate 901 is fixedly connected to the connecting ring 17, and the other end is fixedly connected to the clamping ring 14 on the annular plate 901. Through this structure, both the annular plate 901 and the sliding plate 12 can rotate relative to the filtering unit 10.

[0040] Combined with Figures 7-8 As shown, a round hole 1203 which is matched with the diversion pipe 2 and a strip-shaped groove 1206 which is matched with the partition plate 18 are formed on the sliding plate 12. In addition, a through groove 1202 is formed on the sliding plate 12 outside the round hole 1203, and the inside of the sliding plate 12 is of a cavity structure, so that the spray pipe 11 can be communicated with the sliding plate 12.

[0041] Diversion holes 201 are formed on the outer peripheral wall of the diversion pipe 2 near both ends. Refer to Figures 7-13As shown, the diversion hole 201 is sealed by the baffle 19. Specifically, a water inlet hole 1204 is formed in the inner wall of the circular hole 1203 on the slide plate 12. When the water inlet hole 1204 on the slide plate 12 is aligned with the diversion hole 201 on the diversion pipe 2, the water source in the diversion pipe 2 can be introduced into the inner cavity of the slide plate 12. A strip-shaped insertion groove 1901 is formed in the outer peripheral wall of the baffle 19, and one end of the insertion groove 1901 close to the slide plate 12 extends to the end of the baffle 19. Push blocks 1205 are arranged at positions on both the upper and lower sides of the water inlet hole 1204 on the inner wall of the circular hole 1203, and the push blocks 1205 are elastically matched with the slide plate 12. During actual use, when the slide plate 12 moves vertically to one side of the end cover 9, the push blocks 1205 can drive the baffle 19 to move relative to the diversion pipe 2 through the cooperation with the insertion groove 1901, so that the diversion hole 201 is aligned with the water inlet hole 1204 on the slide plate 12.

[0042] Refer again to Figure 2 As shown, a ring-shaped storage groove 903 is formed on the side of the end cover 9 close to the slide plate 12, and the above-mentioned annular plate 901 is arranged in the storage groove 903 and the top surface of the annular plate 901 is parallel to the side of the end cover 9 close to the slide plate 12. A vertical rod 7 is fixedly arranged on the side of the annular plate 901 away from the slide plate 12. The vertical rod 7 passes through the end cover 9 and is slidably matched with it, and a limiting spring is sleeved on the outer side of the vertical rod 7. The limiting spring is fixedly arranged between the annular plate 901 and the inner end face of the storage groove 903.

[0043] In the initial state, the skateboard 12 is located on one side of the upper end cap 9, and the limiting block 1201 is located at the top position of the limiting groove 601. When raw materials are introduced into the cylinder body 6, the diversion pipe 2 can be driven to rotate. During the rotation of the diversion pipe 2, the skateboard 12 can be driven to rotate through the partition plate 18, and the cylinder body 6 can be driven to rotate synchronously with the skateboard 12 through the cooperation of the limiting block 1201 and the limiting groove 601. At this time, the centrifugal force generated by the cooperation of the cylinder body 6 and the partition plate 18 can throw out the water in the sludge, while the sludge is retained inside the cylinder body 6 by the filtering unit 10 below the skateboard 12. After using for a period of time, when it is necessary to clean the filtering unit 10 below the skateboard 12, the diversion pipe 2 can be driven to rotate in the reverse direction, so that the limiting block 1201 can slide downward relative to the limiting groove 601. Therefore, by using the cooperation of the limiting block 1201 and the limiting groove 601, the skateboard 12 can be driven to move downward, so that the multiple filtering units 10 below the skateboard 12 can be folded up, and the multiple filtering units 10 folded above the skateboard 12 are gradually unfolded. When the skateboard 12 moves downward to a state where it fits with the end cap 9, the nozzle 11 below the skateboard 12 can squeeze the annular plate 901 downward into the end cap 9, so that the multiple filtering units 10 below the skateboard 12 can be stored in the storage groove 903 of the lower end cap 9. In addition, as the skateboard 12 moves downward and fits with the end cap 9, the pushing block 1205 on the inner wall of the round hole 1203 on the skateboard 12 can drive the baffle plate 19 at the diversion hole 201 below to move downward, so that the water inlet hole 1204 on the skateboard 12 is aligned with the diversion hole 201 on the diversion pipe 2. At this time, when water is injected into the diversion pipe 2 by an external water pump, the water flow can be poured into the skateboard 12 through the cooperation of the diversion hole 201 and the water inlet hole 1204 and finally exported through the nozzle 11 below the skateboard 12. The nozzle 11 is beneficial to flushing and cleaning the filtering units 10 stored in the lower end cap 9;

[0044] When the skateboard 12 moves downward and fits with the lower end cap 9, the limiting block 1201 also slides to the bottom position of the limiting groove 601. At this time, through the limiting block 1201 and the limiting groove 601, the skateboard 12 can drive the cylinder body 6 to rotate synchronously. During the rotation of the skateboard 12, the filtering units 10 in the storage groove 903 can be fully cleaned by the nozzle 11 below the skateboard 12, and when the cylinder body 6 rotates with the partition plate 18, the sewage in the cylinder body 6 can be filtered, and the two steps of sludge recovery and filtering unit 10 cleaning can be carried out simultaneously, so that the overall operation is more coherent.

[0045] To sum up, this device, through the setting of the limiting unit, enables the guide tube 2 to move in the vertical direction during the process of driving the slide plate 12 to rotate, which is conducive to storing the filter unit 10 on one side of the slide plate 12 into the end cover 9. The filter unit 10 stored in the end cover 9 can be flushed through the nozzle 11 on one side of the slide plate 12, and the process of flushing the filter unit 10 does not interfere with the process of sludge recovery, so that the overall device is easy to operate and has better continuity.

[0046] Reference Figures 1-7 , Figure 11 As shown, the top wall and the bottom wall of the inner cavity of the slide plate 12 are fixedly provided with a sealing ring 21, the sealing ring 21 is sleeved on the outside of the nozzle 11 and fits with the nozzle 11, and a through slot 1102 is opened on the outer peripheral surface of the nozzle 11 and close to the sealing ring 21, so that the water flow in the slide plate 12 can enter the nozzle 11 through the slot 1102. In the initial state, the slot 1102 is located at the inner side of the sealing ring 21. In specific use, when the slide plate 12 moves downward and fits with the end cover 9, the nozzle 11 below the slide plate 12 can squeeze the annular plate 901 to move downward, and the water in the slide plate 12 can flow into the nozzle 11 through the annular plate 901. The action force between the slide 12 and the nozzle 11 enables the nozzle 11 below the slide 12 to move upward relative to the slide 12, so that the notch 1102 on the lower nozzle 11 can be offset from the sealing ring 21, and the water flow in the slide 12 can be introduced into the lower nozzle 11 and sprayed out. Similarly, when the slide 12 moves upward and fits with the end cover 9, the nozzle 11 above the slide 12 is in a state of conduction with the slide 12. In summary, through this structure, only the nozzle 11 in the end cover 9 can be connected with the slide 12, so that the filter unit 10 stored in the end cover 9 can be cleaned through the nozzle 11.
