[0001] This utility model relates to the field of sludge dewatering technology, and in particular to a sludge dewatering device. Background Technology

[0002] In the field of sludge treatment, dewatering is a key step in achieving sludge reduction and harmlessness. Sludge dewatering devices remove moisture from sludge through the combined action of filtration and compression. The smoothness of the filtration mechanism directly affects the dewatering efficiency and treatment effect. Therefore, dewatering devices that are adapted to the characteristics of sludge and have efficient filtration and impurity removal functions have become important equipment for improving sludge treatment efficiency.

[0003] Existing sludge dewatering devices lack convenient impurity cleaning mechanisms for their filter components. Most devices require the removal of multiple fixing parts to access the filter structure when cleaning impurities, such as the sludge dewatering device in CN223055222U. Most devices lack targeted impurity discharge guidance designs, making the impurity cleaning process time-consuming and labor-intensive. They cannot achieve rapid impurity discharge through structural linkage, which increases the labor intensity of operators and easily causes filter pore blockage due to untimely cleaning, affecting subsequent sludge dewatering. Therefore, we propose a sludge dewatering device to solve this problem. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5 The embodiments provided by this utility model are as follows: A sludge dewatering device includes a conveyor belt 1 and an extrusion belt 2 installed on top of the conveyor belt 1. The extrusion belt 2 and the conveyor belt 1 are prior art, and the sludge dewatering device in CN223055222U can be referred to, and will not be described in detail here. At the same time, the extrusion belt 2 of this application can also be equipped with a brush. A funnel 3 is fixedly installed on the top of the conveyor belt 1. The funnel 3 is located on one side of the extrusion belt 2. Moving shafts 14 are slidably installed on two opposite inner walls of the funnel 3. The moving shafts 14 are equipped with two rectangular plates 10 through a rotating mechanism. A moving mechanism for moving the moving shaft 14 is installed on the side of the funnel 3; On the other two inner walls of the funnel 3, there are discharge holes 8. On the inner walls of the two discharge holes 8, there are movable shafts 9 rotatably installed. On the sides of the two movable shafts 9, there are rectangular holes. Two rectangular plates 10 are slidably installed in the two rectangular holes respectively. The top of the rectangular plate 10 has a plurality of evenly arranged filter holes 18 located between the movable shaft 9 and the moving shaft 14, and collection mechanisms are installed on both sides of the funnel 3.

[0019] like Figure 4 and Figure 5 As shown, the rotating mechanism includes a rotating groove at the bottom of the moving shaft 14. Two shaft grooves and two shaft holes are respectively opened on the inner walls of both sides of the rotating groove. Circular holes are opened on the sides of the two rectangular plates 10. Circular rods 20 are slidably installed in the two shaft holes. One end of each circular rod 20 passes through the two circular holes and extends into the two shaft grooves. A connecting block 19 is fixedly installed at the other end of each circular rod 20. Limiting holes are opened on the side of the connecting block 19. A threaded limiting groove is opened at the end of the moving shaft 14. A limiting bolt 21 is installed in the limiting hole. One end of the limiting bolt 21 is threaded into the threaded limiting groove. When it is necessary to maintain the rectangular plate 10, when the two rectangular plates 10 are in an inverted V shape, after removing the two cover plates 5 and cleaning the collection box 4, rotate the limiting bolt 21 to separate it from the moving shaft 14, and then pull out the connecting block 19 to drive the two round rods 20 out of the moving shaft 14. At this time, the rectangular plate 10 is separated from the moving shaft 14. Then, the rectangular plate 10 can be taken out of the collection box 4 for maintenance. After maintenance, first align the rectangular plate 10 with the rectangular hole on the moving shaft 9 and insert it, then reach the rotating groove at the bottom of the moving shaft 14. Then, align the round rod 20 with the rectangular plate 10 and insert it, and then fix it with the limiting bolt 21.

[0020] like Figure 3As shown, the moving mechanism includes a mounting shaft 13 fixedly installed on the side of the funnel 3, a swing arm 16 rotatably sleeved on the mounting shaft 13, a pressing hole 12 opened on the side of the swing arm 16, a pressure column 15 fixedly installed on the end of the moving shaft 14 away from the connecting block 19, one end of the pressure column 15 passing through the pressing hole 12, a fixing hole opened on one side of the pressing hole 12, two threaded fixing grooves opened on the side of the funnel 3, a fixing bolt 22 is provided in the fixing hole, one end of the fixing bolt 22 is threaded into one of the threaded fixing grooves 11; a handle 17 is rotatably installed on the side of the swing arm 16 away from the funnel 3. When there are too many impurities on the rectangular plate 10, the fixing bolt 22 is rotated to move it out of the threaded fixing groove 11. Then, the handle 17 is gripped and rotated. The rotation of the handle 17 drives the swing arm 16 to rotate around the mounting shaft 13. The rotation of the swing arm 16 causes the inner wall of the squeezing hole 12 to squeeze the pressure column 15, thereby causing the moving shaft 14 to move upward. The movement of the moving shaft 14 causes the two rectangular plates 10 to rotate around the two round rods 20 respectively. At the same time, the two rectangular plates 10 slide in the two rectangular holes respectively. The tops of the two rectangular plates 10 are separated from the inner top walls of the two collection boxes 4 respectively. When the two rectangular plates 10 rotate from a V shape to an inverted V shape, the fixing bolt 22 corresponds to the position of the threaded fixing groove 11 located above. The fixing bolt 22 is rotated in the opposite direction to make it enter the threaded fixing groove 11, thereby completing the fixation of the position of the moving shaft 14. At this time, the impurities on the two rectangular plates 10 can fall into the two collection boxes 4 respectively due to gravity. If there are impurities that have not fallen, the staff can use a wooden stick to knock them down, so that the impurities can fall into the cover plate 5.

[0021] like Figure 3 As shown, the collection mechanism includes a collection box 4 fixedly installed on the side of the funnel 3. A cover plate 5 is detachably installed on the side of the collection box 4 away from the funnel 3. An avoidance hole corresponding to the discharge hole 8 is opened on the inner wall of the collection box 4 near the funnel 3. The rectangular plate 10 passes through the avoidance hole and contacts the inner top wall of the collection box 4 on the side away from the moving shaft 14. The cover plate 5 facilitates later opening and cleaning, and the collection box 4 facilitates collection.

[0022] like Figure 3 As shown, a gap is left between the top of the movable shaft 9 and the inner top wall of the discharge hole 8. The advantage of this arrangement is that impurities located above the rectangular plate 10 can pass through and fall into the collection box 4 for collection.

[0023] like Figure 3 As shown, movable holes 7 are provided on both inner walls of the funnel 3, and two sliding holes are provided on the top of the funnel 3. The two sliding holes are connected to the two movable holes 7 respectively. The two ends of the movable shaft 14 pass through the two movable holes 7 respectively, and two sliding plates 6 are fixedly sleeved on the movable shaft 14. The two sliding plates 6 are slidably installed in the two sliding holes respectively. By setting the sliding plates 6, the sliding holes can be blocked to prevent sludge from passing through.

[0024] like Figure 4 As shown, the height of the movable shaft 9 is higher than the height of the moving shaft 14, and the rectangular plate 10 is inclined, with both sides of the rectangular plate 10 contacting the inner walls of the funnel 3. The advantage of this arrangement is that the two rectangular plates 10 form a V-shape, thereby filtering the sludge.

[0025] Working principle: When in use, sludge is put in through funnel 3. Large particles of impurities in the sludge are filtered by multiple filter holes 18 on two rectangular plates 10. After filtration, the sludge falls onto conveyor belt 1 and is transported by conveyor belt 1. The sludge can be dewatered by the cooperation of conveyor belt 1 and extrusion belt 2. When there are too many impurities on the rectangular plate 10, the fixing bolt 22 is rotated to move it out of the threaded fixing groove 11. Then, the handle 17 is held and rotated. The rotation of the handle 17 drives the swing arm 16 to rotate around the mounting shaft 13. The rotation of the swing arm 16 causes the inner wall of the squeezing hole 12 to squeeze the pressure column 15, thereby causing the moving shaft 14 to move upward. The movement of the moving shaft 14 drives the two rectangular plates 10 to rotate around the two round rods 20 respectively. At the same time, the two rectangular plates 10 slide in the two rectangular holes respectively. The tops of the two rectangular plates 10 are separated from the inner top walls of the two collection boxes 4 respectively. When the two rectangular plates 10 rotate from a V shape to an inverted V shape, the fixing bolt 22 corresponds to the position of the threaded fixing groove 11 located above. The fixing bolt 22 is rotated in the opposite direction to enter the threaded fixing groove 11, thereby completing the fixation of the position of the moving shaft 14. At this time, the impurities on the two rectangular plates 10 can fall into the two collection boxes 4 respectively due to gravity. If there are impurities that have not fallen, the staff can use a wooden stick to knock them down, so that the impurities can fall into the cover plate 5. When it is necessary to maintain the rectangular plate 10, when the two rectangular plates 10 are in an inverted V shape, after removing the two cover plates 5 and cleaning the collection box 4, rotate the limiting bolt 21 to separate it from the moving shaft 14, and then pull out the connecting block 19 to drive the two round rods 20 out of the moving shaft 14. At this time, the rectangular plate 10 is separated from the moving shaft 14. Then, the rectangular plate 10 can be taken out of the collection box 4 for maintenance. After maintenance, first align the rectangular plate 10 with the rectangular hole on the moving shaft 9 and insert it, then reach the rotating groove at the bottom of the moving shaft 14. Then, align the round rod 20 with the rectangular plate 10 and insert it, and then fix it with the limiting bolt 21.

[0026] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
