DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10 As shown, a sludge recycling device and a utilization method include a shell 1 and a cylinder 6 arranged in the shell 1, both ends of the cylinder 6 are open, and the cylinder 6 and the shell 1 are coaxially arranged, and end covers 9 are rotatably arranged at the two ends of the cylinder 6, and the end covers 9 pass through the shell 1 and are fixedly connected to the shell 1; A slide plate 12 is slidably arranged inside the cylinder 6. The slide plate 12 is a circular structure, and the outer peripheral wall of the slide plate 12 contacts the inner wall of the cylinder 6. In actual use, the slide plate 12 can move in the vertical direction relative to the cylinder 6. Figure 2 As shown, a plurality of connecting rings 17 are arranged on both the upper and lower sides of the slide plate 12, and the connecting rings 17 are fitted to the inner wall of the cylinder 6, and a rubber ring can be fixedly embedded on the outer wall of the connecting ring 17 to improve the friction between the connecting ring 17 and the cylinder 6, and an annular plate 901 is installed on the side of the end cover 9 close to the slide plate 12, and the annular plate 901 and the end cover 9 are elastically matched, so that the annular plate 901 can move in the vertical direction relative to the end cover 9, specifically, the annular plate 901 is close to the side of the slide plate 12 and the connecting ring 17, and the slide plate 12 and the adjacent connecting ring 17 are A filter unit 10 is arranged between the cylinder 6 and between two adjacent connecting rings 17. The filter unit 10 adopts a flexible structure. In specific application, the sewage is introduced into the cylinder 6, and the sewage can be filtered through the filter unit 10 in the cylinder 6. A plurality of filter holes are evenly opened on the side wall of the cylinder 6, which is conducive to the discharge of sewage and the retention of sludge on the inner side of the cylinder 6. When the slide plate 12 moves to the side of the end cover 9 in the vertical direction, the plurality of filter units 10 on one side of the slide plate 12 can be stored in the end cover 9, which is conducive to the later flushing of the stored filter units 10.

[0021] Reference Figure 2-Figure 10 As shown, a guide tube 2 is coaxially arranged inside the cylinder 6, and a partition 18 is fixedly arranged on the outer peripheral wall of the guide tube 2. The number of the partition 18 is set to at least one, and the guide tube 2 and the partition 18 both pass through the slide plate 12 and slide with the slide plate 12. The slide plate 12 and the cylinder 6 are matched through a limiting unit, so that when the guide tube 2 drives the slide plate 12 to rotate, the slide plate 12 can move in the vertical direction relative to the cylinder 6.

[0022] A plurality of nozzles 11 are installed on the top and bottom surfaces of the slide plate 12. The nozzles 11 are connected to the slide plate 12 and are elastically matched with each other. When the slide plate 12 is moved to one side of the end cover 9 by the limiting unit, the nozzles 11 can be inserted into the end cover 9, so that the folded filter unit 10 is flushed by the nozzles 11. A plurality of spray holes 1101 are opened on the outer peripheral wall of the nozzle 11. The spray holes 1101 on the nozzle 11 are arranged opposite to the filter unit 10 stored in the end cover 9.

[0023] The limiting unit includes a limiting block 1201, which is fixedly arranged at the outer peripheral wall of the slide plate 12, and a limiting groove 601 is provided on the inner wall of the cylinder 6 to slide with the limiting block 1201. The limiting groove 601 is set in a spiral shape. In actual use, although the cylinder 6 can rotate relative to the end cover 9, the friction between the cylinder 6 and the end cover 9 can be increased. In this way, when the guide tube 2 drives the slide plate 12 to rotate, the cylinder 6 can remain stable due to the large friction between the cylinder 6 and the end cover 9. At this time, the cooperation between the limit block 1201 and the limit groove 601 can drive the slide plate 12 to move in the vertical direction, and when the slide plate 12 moves to the side of the end cover 9, the limit block 1201 moves to the end position of the limit groove 601. At this time, the guide tube 2 drives the slide plate 12 to rotate, and the cooperation between the limit block 1201 and the limit groove 601 can drive the cylinder 6 to rotate synchronously. Through this structure, the sewage can be thrown out, and the sludge is retained in the cylinder 6 by the filter unit 10, thereby realizing the recycling of the sludge; Combination Figure 2-Figure 4 As shown, one side of the annular plate 901 and the slide plate 12 that are arranged opposite to each other are rotatably connected with a retaining ring 14, the filter unit 10 located between two adjacent connecting rings 17 is fixedly connected to the connecting ring 17, one end of the filter unit 10 located at the slide plate 12 is fixedly connected to the connecting ring 17, and the other end is fixedly connected to the retaining ring 14 on the slide plate 12. Similarly, one end of the filter 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 retaining ring 14 on the annular plate 901. Through this structure, the annular plate 901 and the slide plate 12 can both rotate relative to the filter unit 10.

[0024] Combination Figure 7-Figure 8 As shown, the slide plate 12 is provided with a circular hole 1203 cooperating with the guide tube 2 and a strip groove 1206 cooperating with the partition 18. In addition, the slide plate 12 is provided with a through groove 1202 on the outside of the circular hole 1203, and the interior of the slide plate 12 is a cavity structure, so that the nozzle 11 can be connected to the slide plate 12.

[0025] The outer peripheral wall of the flow guide pipe 2 and the positions near the two ends are provided with flow guide holes 201. Figure 7-Figure 13 As shown, the guide hole 201 is sealed by the baffle plate 19. Specifically, a water inlet hole 1204 is opened on 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 guide hole 201 on the guide tube 2, the water source in the guide tube 2 can be introduced into the inner cavity of the slide plate 12. A strip-shaped plug-in groove 1901 is opened on the outer peripheral wall of the baffle plate 19, and the plug-in groove 1901 extends to the baffle plate 19 near one end of the slide plate 12. 9, push blocks 1205 are provided on the inner wall of the circular hole 1203 and at the upper and lower sides of the water inlet hole 1204. The push blocks 1205 are elastically matched with the slide plate 12. In actual use, when the slide plate 12 moves to one side of the end cover 9 in the vertical direction, the push blocks 1205 can drive the baffle plate 19 to move relative to the guide tube 2 by cooperating with the plug-in groove 1901, so that the guide hole 201 is aligned with the water inlet hole 1204 on the slide plate 12.

[0026] Refer again Figure 2 As shown, an annular storage groove 903 is provided on one side of the end cover 9 close to the skateboard 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 skateboard 12, and a vertical rod 7 is fixedly arranged on the side of the annular plate 901 away from the skateboard 12, the vertical rod 7 passes through the end cover 9 and slides with it, and a limit spring is sleeved on the outer side of the vertical rod 7, and the limit spring is fixedly arranged between the annular plate 901 and the inner end surface of the storage groove 903.

[0027] In the initial state, the slide plate 12 is located on one side of the upper end cover 9, and the limit block 1201 is located at the top position of the limit groove 601. When the raw material is introduced into the cylinder 6, the guide tube 2 can be driven to rotate. During the rotation of the guide tube 2, the partition 18 can drive the slide plate 12 to rotate, and the cooperation between the limit block 1201 and the limit groove 601 can drive the cylinder 6 to rotate synchronously with the slide plate 12. At this time, the centrifugal force generated by the cylinder 6 and the partition 18 can throw out the water in the sludge, and the sludge is retained in the cylinder 6 by the filter unit 10 under the slide plate 12. After a period of use, when the filter unit 10 under the slide plate 12 needs to be cleaned, the guide tube 2 can be driven to rotate in the opposite direction, so that the limit block 1201 can slide downward relative to the limit groove 601. Therefore, the cooperation between the limit block 1201 and the limit groove 601 can drive the slide plate 12 to move downward, so that the multiple filter units 10 under the slide plate 12 can be folded up When the slide plate 12 moves downward to fit with the end cover 9, the nozzle 11 below the slide plate 12 can press the annular plate 901 downward into the end cover 9, so that the multiple filter units 10 below the slide plate 12 can be stored in the storage groove 903 of the lower end cover 9. In addition, as the slide plate 12 moves downward and fits with the end cover 9, the push block 1205 on the inner wall of the circular hole 1203 on the slide plate 12 can It is able to drive the baffle plate 19 at the lower guide hole 201 to move downward, so that the water inlet hole 1204 on the slide plate 12 is aligned with the guide hole 201 on the guide pipe 2. At this time, when water is injected into the guide pipe 2 through an external water pump, the water flow can be poured into the slide plate 12 through the cooperation of the guide hole 201 and the water inlet hole 1204 and finally discharged through the nozzle 11 under the slide plate 12, which is conducive to flushing and cleaning the filter unit 10 stored in the lower end cover 9; When the slide plate 12 moves downward and fits with the end cover 9 below, the limit block 1201 also slides to the bottom position of the limit groove 601. At this time, the slide plate 12 can drive the cylinder 6 to rotate synchronously through the limit block 1201 and the limit groove 601. During the rotation of the slide plate 12, the nozzle 11 under the slide plate 12 can be used to fully clean the filter unit 10 in the storage tank 903, and the cylinder 6 can filter the sewage in the cylinder 6 when the partition 18 rotates, and the two steps of sludge recovery and filter unit 10 cleaning can be carried out simultaneously, so that the overall operation is more consistent.

[0028] 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.

[0029] Reference Figure 1-Figure 7 , Fig.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.
