[0002] Silt refers to fine-grained soil containing organic matter that is deposited in a still water or slow-flowing water environment. It generally exists in rivers. Excessive accumulation of silt in rivers will cause the riverbed to become shallower and the water storage capacity to decrease, which will cause the water quality of the river to deteriorate and damage the water quality environment. Therefore, when there is too much silt accumulated in the riverbed, it is necessary to use a silt dehydration and solidification device to treat it. In order to ensure the cleanliness of urban rivers, it is necessary to clean urban rivers regularly. In the prior art, the riverbed silt is usually sucked into a transfer vehicle, which is then transported to a treatment plant for subsequent treatment.

[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] Embodiment 1:

[0043] Please refer to Figure 1-Figure 4 , a sludge dewatering device that is easy to clean, comprising:

[0044] A conveying mechanism 1, wherein a feed hopper 2 is disposed at the upper portion of one end of the conveying mechanism 1, and a feeding port 3 is disposed at the other end of the conveying mechanism 1; the sludge can be conveyed to the inside of the conveying mechanism 1 through the feed hopper 2, and the sludge is conveyed toward the feeding port 3 through the conveying mechanism 1 and discharged outward through the feeding port 3;

[0045] The fixed frame 4 is arranged at the end of the conveying mechanism 1 and close to one end of the feeding port 3. The lower end of the fixed frame 4 is provided with a water filter conveyor belt 5, and the upper end of the fixed frame 4 is provided with a filter press conveyor belt 6. It can be seen that the sludge discharged from the feeding port 3 falls to the upper end of the water filter conveyor belt 5, and the sludge is transported by the water filter conveyor belt 5, and the sludge is squeezed by the filter press conveyor belt 6 to achieve filter pressing and dehydration of the sludge.

[0046] A cleaning mechanism 7 is arranged inside the fixing frame 4, and the cleaning mechanism 7 is located between the water filter conveyor belt 5 and the filter press conveyor belt 6; after the sludge is dehydrated, the cleaning mechanism 7 moves to between the water filter conveyor belt 5 and the filter press conveyor belt 6 while keeping the water filter conveyor belt 5 and the filter press conveyor belt 6 moving, so that the surfaces of the water filter conveyor belt 5 and the filter press conveyor belt 6 can be cleaned at the same time;

[0047] The movable seat 8 is arranged at a position on the side of the fixed frame 4, and a J-shaped slide groove 9 is opened on the side of the fixed frame 4. The movable seat 8 is located inside the J-shaped slide groove 9, and the movable seat 8 is movably connected to the J-shaped slide groove 9. Further, in order to make the movement of the movable seat 8 smoother, the four end corners of the movable seat 8 are rotatably connected with movable wheels 15, and the movable wheels 15 are rollingly connected with the J-shaped slide groove 9. A mounting seat 16 is fixed on the outer side of the movable seat 8, and the telescopic end of the jacking mechanism 12 is rotatably connected with the mounting seat 16, and the end of the cleaning mechanism 7 is fixed to the movable seat 8; specifically, the cleaning mechanism 7 includes a brush roller 13, and water spray pipes 14 are arranged on both sides of the brush roller 13. The brush roller 13 and the water spray pipe 14 are arranged in parallel, and the end of the brush roller 13 is rotatably connected to the movable seat 8. The brush roller 13 is driven by a motor, and the end of the water spray pipe 14 is fixedly connected to the movable seat 8. A plurality of nozzles are evenly arranged on the upper part of the water spray pipe 14 along the length direction, wherein the water spray pipe 14 is connected to an external water source through a pipeline.

[0048] The linear motor 10 is arranged at a position outside the fixed frame 4. The upper sliding part of the linear motor 10 is connected to the adjustment seat 11.

One end of the lifting mechanism 12 is rotatably connected to the adjustment seat 11, and the telescopic end of the lifting mechanism 12 is rotatably connected to the movable seat 8.

[0049] It can be seen that when the cleaning mechanism 7 is located between the water filter conveyor belt 5 and the filter press conveyor belt 6, the external water source is sprayed between the water filter conveyor belt 5 and the filter press conveyor belt 6 through the nozzle on the water spray pipe 14, and the brush roller 13 is started to rotate to brush the surfaces of the water filter conveyor belt 5 and the filter press conveyor belt 6; after cleaning, the linear motor 10 drives the adjustment seat 11 to move, and during the movement of the adjustment seat 11, the jacking mechanism 12 pushes the moving seat 8 to move toward the upwardly tilted end of the J-shaped chute 9. When the moving seat 8 moves to the part close to the tilted end of the J-shaped chute 9, the jacking mechanism 12 is started to push the moving seat 8 to move to the tilted end of the J-shaped chute 9, thereby raising the height position of the cleaning mechanism 7, thereby avoiding the next sludge dewatering operation.

[0050] Embodiment 2:

[0051] The sludge dewatering device for easy cleaning provided in Example 1 is further optimized, specifically, as follows: Figure 5 As shown, the conveying mechanism 1 includes a conveying shell 17, the lower end of the feed hopper 2 is fixedly connected to the upper part of one end of the conveying shell 17, the feeding port 3 is detachably connected to the other end of the conveying shell 17, a screw conveying shaft 18 is arranged inside the conveying shell 17 along the axial direction, a driving motor 19 is fixed to the end of the conveying shell 17 away from the feeding port 3, and the output end of the driving motor 19 is fixedly connected to the screw conveying shaft 18.

[0052] Through the above structural design, the driving motor 19 is started to drive the screw conveying shaft 18 to rotate inside the conveying shell 17. After the sludge enters the conveying shell 17 through the feed hopper 2, the rotating screw conveying shaft 18 conveys the sludge toward the feeding port 3, and the sludge is finally squeezed out through the feeding port 3.

[0053] Embodiment 3:

[0054] The sludge dewatering device for easy cleaning provided in Example 1 is further optimized, specifically, as follows: Figure 6 As shown, the feeding port 3 includes a plastic section 20, and a protective section 21 is buckled and connected inside the plastic section 20. A sealing ring 22 is provided at one end of the protective section 21 close to the conveying shell 17. The plastic section 20, the protective section 21, and the sealing ring 22 are all detachably fixedly connected to the conveying shell 17 by bolts. In order to facilitate the positioning and placement of the protective section 21, a plurality of positioning plates 23 are fixedly connected to the peripheral side of the protective section 21. Positioning grooves 24 are provided at the ends of the plastic section 20 and at positions corresponding to the positioning plates 23. The positioning plates 23 are located inside the positioning grooves 24.

[0055] Through the above-mentioned structural design, the inner side of the plastic surgery section 20 is protected by the protective section 21, thereby reducing the wear of the inner side of the plastic surgery section 20 by the stones contained in the sludge during the sludge extrusion process; the positioning and fixation of the protective section 21 and the plastic surgery section 20 can be achieved through the structural cooperation of the positioning plate 23 and the positioning groove 24, and the sludge can be prevented from flowing out through the gap between the feeding port 3 and the conveying shell 17 through the sealing ring 22. The plastic surgery section 20, the protective section 21 and the sealing ring 22 can be removed or replaced by simply removing the bolts used to fix the feeding port 3.
