[0027] in, Figure 1 The reference direction coordinate system of the embodiment of the present application is given. Figure 1 The embodiment of the present application is described with reference to the direction shown.

[0028] The embodiment of the present application provides a sand removal device, see Figures 1 to 5The sand removal device comprises a box 100 for containing sewage and a filter plate 200 for removing sand. The filter plate 200 is arranged in the box 100 along the cross section of the box 100. The filter plate 200 is provided with a plurality of filter holes. A cleaning assembly 300 is arranged in the box 100. The cleaning assembly 300 comprises a roller body 310. The outer periphery of the roller body 310 is provided with a protrusion 320 that is engaged with the filter hole. The plurality of protrusions 320 are arranged corresponding to the plurality of filter holes. The box 100 is provided with a driving assembly 400 that can drive the roller body 310 to roll along the surface of the filter plate 200. The roller body 310 is provided with protrusions 320 that engage with the filter holes. When the cleaning component 300 moves along the filter plate 200, the roller body 310 rolls along the surface of the filter plate 200. At this time, the multiple protrusions 320 that engage with the filter holes extend into the filter holes in turn to dredge the filter plate 200, which ensures that when desanding sewage, the roller body 310 can continuously dredge the blockage on the filter plate 200 and continuously brush the clogged sand, thereby ensuring that the entire desanding filter plate can perform continuous and efficient sewage filtering.

[0029] In some embodiments, a plurality of filter plates 200 are provided in the box body 100 along the height direction, and a cleaning assembly 300 is provided on each filter plate 200. Only one end of the filter plate 200 is connected to the inner wall of the box body 100. Therefore, even when the dredging efficiency of the roller body 310 is lower than the entry efficiency of the sewage, a large amount of sewage can also quickly reach the bottom filter plate 200 through the other side (the side with a gap between the filter plate 200 and the box body 100) for sand removal, thereby preventing a large amount of sewage from accumulating, further ensuring the sand removal efficiency of the sewage. In other words, when the sewage enters through the water inlet pipe 131, it will first contact the upper part of the upper filter plate 200 for preliminary filtering and sand removal. When the filtration efficiency of the upper filter plate 200 is lower than the falling efficiency of the water source, a large amount of water will continue to fall along the bottom of the inclined filter plate 200, so that it reaches the lower filter plate 200 for sand removal and filtration again, thereby achieving efficient sand removal of the water source.

[0030] The cleaning assembly 300 includes a gear 330 fixedly connected to a roller body 310, and a tooth block 210 meshing with the gear 330 is provided on the filter plate 200. A plurality of tooth blocks 210 are arranged at intervals on the filter plate 200 to form a running path for the gear 330. In other words, during the movement of the roller body 310, the position of the gear 300 corresponds to the position of the tooth block 210, and the two mesh with each other, so that the roller body can roll along the surface of the filter plate 200, and the protrusion 320 extends into the filter hole while rolling.

[0031] In some embodiments, the filter plate 200 is tilted along the length direction of the box body 100. The tilted setting of the entire filter plate 200 can cause the sediment to accumulate in the collection trough 220 at the bottom thereof. The roller body 310 is arranged along the width direction of the filter plate 200. The gear 330 is arranged at both ends of the roller body 310. The gear 330 is coaxially connected to the roller body 310. The gear blocks 210 are located on both sides of the surface of the filter plate 200 along the width direction of the box body 100, and are used to drive the roller body 310 to move and dredge.

[0032] The driving assembly 400 includes a moving component 410 that can move along the length direction of the filter plate 200 . The moving component 410 can push the cleaning assembly 300 to move along the length direction of the filter plate 200 .

[0033] The driving assembly 400 includes a screw rod 420 arranged along the length direction of the filter plate 200 , and the moving component 410 includes a sleeve matched with the screw rod 420 , and the moving component 410 is connected to the outer thread of the screw rod 420 .

[0034] See also Figure 2 , a reserved groove 110 is provided on the inner wall of the box 100, and the screw rod 420 is installed in the reserved groove 110. The reserved groove can provide a more solid support to ensure that the screw rod is installed stably. This helps to reduce vibration and noise and increase the reliability of the entire sand removal device; and through the design of the reserved groove, it is easier to control the position and direction of the screw rod to ensure that it maintains the correct trajectory and alignment during movement; when maintenance or replacement of the screw rod is required, the reserved groove can simplify the operation and reduce the time and tools required for maintenance; the reserved groove can make more efficient use of space, especially under limited space conditions, this installation method can save space in the box 100; the reserved groove to install the screw rod usually looks neater and more beautiful.

[0035] In some embodiments, the screw rod 420 extends to the outside of the housing 100. Figure 1A driving motor 120 is installed on the outside of the box body 100 to drive the screw rod 420 to rotate along its axial direction, which is used to drive the cleaning component 300 to dredge the filter plate 200. The driving motor 120 is coaxially connected to the screw rod 420. The inclination angle of the screw rod 420 is the same as the inclination angle of the filter plate 200. When the driving motor 120 is started, the screw rod 420 coaxially connected to its top end will rotate. When the screw rod 420 rotates, since the external thread is connected with the moving part 410, the moving part 410 will move on the screw rod 420. When the moving part 410 moves, This will drive the gear 330 and the coaxially connected roller body 310 to move, and when the gear 330 moves, it will mesh with the tooth block 210 outside the filter plate 200, so that the gear 330 drives the roller body 310 to rotate, and when the roller body 310 rotates, the protrusions 320 evenly distributed on the outside can continuously contact and dredge the mesh holes on the filter plate 200 to achieve the dredging effect, and as the roller body 310 continues to move and rotate, it can also roll and brush the sand accumulated on the filter plate 200 down, and finally, fall into the collection tank 220 for collection.

[0036] In some embodiments, a bearing is provided at the center of the gear 330 , and the moving component 410 is rotatably connected to the gear 330 via the bearing.

[0037] See also Figure 3 A collecting groove 220 is provided between the bottom end of the filter plate 200 and the inner wall of the box body 100. Specifically, the collecting groove 220 is installed integrally with the filter plate. The collecting groove 221 is arranged along the width direction of the box body 100 and passes through one side outer wall of the box body 100. A handle 221 is provided at the end of the collecting groove 221. The handle 221 is located on the outer wall of the box body 100. The settled sand cleaned by the cleaning component is dredged and falls into the interior of the collecting groove 220, so as to be discharged from the outside of the box body 100.

[0038] See also Figure 1 The top of the box body 100 is provided with an adaptable cover body 130, and the cover body 130 is provided with a water inlet pipe 131 connected with the inside of the box body 100. The bottom of the box body 100 is provided with a water outlet pipe 140 connected with the inside thereof, and the water outlet pipe 140 is arranged to penetrate the outer side of the bottom of the box body 100 for discharging sewage.

[0039] See also Figure 1A fixed base 150 is provided at the bottom of the box body 100. The fixed base 150 is arranged in a rectangular structure and is used for supporting and placing the entire sand removal device. The top of the fixed base 150 and the water inlet pipe 131 penetrate each other. The water inlet pipe 131 is used for the entry of sewage. The fixed base 150 can provide stable support, so that the box body is more stable when placed on a flat surface to prevent tilting or shaking; the fixed base can protect the box body, reduce the wear caused by direct contact between the box body and the ground, and extend the service life of the box body; the fixed base can also isolate the vibration or impact from the ground, and protect the items inside the box body from external influences; the design of the fixed base can increase the overall aesthetics of the box body, making it look more neatly processed and professional.

[0040] In the prior art, when using the sand removal device on the market, when removing sand, the sewage water source is simply poured into a vibrating filter screen, and the sewage and sand are separated by the continuous vibration of the screen. However, in the process of sewage treatment, the volume of sewage is generally very large, and the filtering area of ​​the filter screen is relatively limited. Therefore, in the long-term sewage treatment process, as the mesh holes are continuously blocked, the amount of sand continues to increase, which will gradually reduce the filtration efficiency of the sewage. In order to ensure the filtration efficiency, it is necessary to continuously process and collect the sand, which results in the whole device being not only inefficient when working, but also too cumbersome and complicated in the operation steps. When the sand removal device in the present application is in use, first the entire sand removal device is placed in a suitable position under the action of the fixed base 150, and then the sewage to be treated enters the interior of the entire box 100 through the water inlet pipe 131, and then reaches the top of the filter plate 200 for sand removal. During the sand removal work, the cleaning component 300 continuously dredges the mesh of the filter plate 200. At the same time, when the sewage entry rate is greater than the dredging efficiency of the filter plate 200, due to the large amount of water entering, it will pass through the gap between the filter plate 200 and the inner wall of the box 100 and quickly reach the filter plate 200 below for sand removal, thereby ensuring that the water source is continuously and efficiently dredged to ensure that water accumulation does not occur.
