Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering machine technology, specifically a sludge dewatering machine with a sludge conveying device. Background Technology

[0002] A sludge treatment method involves removing water from fluidized raw, concentrated, or digested sludge, transforming it into semi-solid or solid sludge blocks. After dewatering, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment. Currently, existing sludge dewatering machines do not have easily disassembled screen plate components; they simply use scrapers to remove blockages from the outside of the screen plate components. However, blockages are usually caused by materials clogging the pores, and direct scraping is inconvenient for cleaning and unblocking the screen plate components, thus compromising usability.

[0003] A search revealed a sludge dewatering machine with publication number CN220245875U, which includes a base plate. An inclined plate is fixedly connected to the top of the base plate, and support rods are fixedly connected to the four corners of the inclined plate. Limiting rings are respectively provided above the two ends of the top of the inclined plate, and a rotating cylinder is provided between the two sets of limiting rings. This technical solution also has the aforementioned technical problems. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-6A sludge dewatering machine with a sludge conveying device includes a base plate 1 forming an assembly plane. A sludge tank 25, a water tank 26, and a sludge pump 8 are arranged on the top of the base plate 1. A pipe is connected to the water tank 26 to facilitate water discharge. Both the sludge tank 25 and the water tank 26 are placed on top of the base plate 1, while the sludge pump 8 is installed on top of the base plate 1. A processing cylinder 2 with openings at both ends is inclined above the base plate 1, and three equally spaced openings are provided on the surface of the processing cylinder 2. Each opening contains a screen plate 3, which blocks the openings. The screen plate 3 has water outlet holes 4 to allow water from the sludge to pass through. The vertical position of the water tank 26 is precisely... Located below the sieve plate 3, the water passing through the sieve plate 3 is contained in the water tank 26. To support the entire treatment cylinder 2 and allow it to rotate, two fixing rings 10 are integrally formed on the surface of the treatment cylinder 2. The outer side of the fixing rings 10 is movably covered by a limiting ring 11. The inner wall of the limiting plate 11 is provided with an annular groove that matches the fixing rings 10, so that the fixing rings 10 and the limiting rings 11 can rotate relative to each other. The bottom of the limiting ring 11 is fixedly connected to a vertically downward extending support plate 12. The bottom of the support plate 12 is fixedly installed on the top of the base plate 1. Because the treatment cylinder 2 is inclined, the two support plates 12 are only different in length, so that the treatment cylinder 2 is inclined when the bottom of the two support plates 12 is installed on the top of the base plate 1.

[0025] To transport sludge into the treatment cylinder 2, a sealing cap 9 is fixedly connected to the sludge discharge pipe at the top of the sludge pump 8. A protrusion is fixedly connected to the side of the sealing cap 9 and is inserted into the treatment cylinder 2. The protrusion is made of rubber and its size is slightly larger than the inner diameter of the treatment cylinder 2. This ensures a good seal between the sealing cap 9 and the treatment cylinder 2 after the protrusion is inserted into the treatment cylinder 2. A suction pipe is fixedly connected to one side of the sludge pump 8. The suction pipe is used to suck up the sludge and then it is introduced into the treatment cylinder 2 through the sludge discharge pipe. This completes the sludge transportation work. It should be noted that the sludge is treated with chemicals before being input. Therefore, the sludge introduced into the treatment cylinder 2 through the sludge pump 8 has already been treated with chemicals.

[0026] To transport the sludge inside the treatment cylinder 2 and perform sludge dewatering, two vertically extending supports 13 are installed on the top of the base plate 1. A working motor 5 is set between the two supports 13 and mounted on the supports 13. The installation stability of the working motor 5 is improved by using the two supports 13. A working shaft 6 is fixedly connected to the output shaft of the working motor 5. The working shaft 6 extends into the interior of the treatment cylinder 2 and a spiral pusher plate 7 is fixedly connected to the working shaft 6. When the working motor 5 is working, it will drive the spiral pusher plate 7 to rotate through the working shaft 6. The water in the sludge falls through the water outlet 4, and then the spiral pusher plate 7 will drive the dewatered sludge to gradually move towards the higher part of the tilt angle of the treatment cylinder 2.

[0027] Due to the extended span of the working shaft 6, a support ring 27 is fitted onto the surface of the working shaft 6, and a bearing 28 is installed on the inner wall of the support ring 27. The inner wall of the inner ring of the bearing 28 is in close contact with the surface of the working shaft 6, and the surface of the outer ring is fixedly connected to the support ring 27. A vertical plate 29 with rounded upper corners is also fixedly welded to the upper part of the support ring 27. A bending frame 31 is connected to the side of the vertical plate 29 through a horizontally extending horizontal plate 30. The bending frame 31 is U-shaped and is mounted on the working shaft 6. The machine 5 is externally mounted, and its two end corners are fixedly connected to the two brackets 13. In this way, the working shaft 6 is supported by the support ring 27, bearing 28, vertical plate 29, horizontal plate 30 and bending frame 31. This avoids the working shaft 6, the spiral push plate 7 and some working pressure being directly transmitted to the working motor 5. The working motor 5 only needs to provide a stable rotational force, which ensures the normal service life of the working motor 5. The working motor 5 in the sludge dewatering machine is existing technology, and its detailed model will not be described here.

[0028] Three fixing plates 14 are fixedly connected to the side of the processing cylinder 2. The positions of the fixing plates 14 correspond exactly to the screen plates 3. A long strip rod 15 is movably inserted into each fixing plate 14. Two side blocks 16 are fixedly welded to each screen plate 3. The rod 15 passes through the side blocks 16, and the two are movably connected. The side blocks 16 will not affect the operator from removing the rod 15 from the fixing plate 14. A circular stabilizing ring 17 is fixedly welded to the surface of the processing cylinder 2. Three slots 18 are evenly spaced on the stabilizing ring 17. The specifications of the slots 18 match the diameter of the rod 15. 15 is inserted into the slot 18, and its end away from the fixed plate 14 extends beyond the stabilizing ring 17 and is connected to a limiting shell 19 with a side opening. Two positioning rods 20 are fixedly welded to the side of each limiting shell 19. The end of the positioning rod 20 away from the limiting shell 19 is movably inserted into the stabilizing ring 17. When the entire processing cylinder 2 is tilted, the position of the screen plate 3 is stabilized after the positioning rod 20 is movably inserted into the stabilizing ring 17, preventing it from falling out of the opening on the processing cylinder 2. However, to further stabilize the position of the screen plate 3 and prevent misoperation, this technical solution includes a limiting shell 19 with a side opening. A track 23 is fixedly connected to the inner wall of the 9. A limiting plate 21 matching the inner wall of the limiting shell 19 is slidably connected to the surface of the track 23. The side of the limiting plate 21 is in contact with the inner wall of the limiting shell 19. The track 23 is designed to prevent the limiting plate 21 from moving on the inner wall of the limiting shell 19 and to prevent the limiting plate 21 from detaching from the limiting shell 19. A limiting rod 22 is fixedly connected to the side of the limiting plate 21 facing the processing cylinder 2. The end of the limiting rod 22 away from the limiting plate 21 is movably inserted into the processing cylinder 2, and the end of the limiting rod 22 is not inserted. Inside the processing cylinder 2, to stabilize the position of the limiting plate 21 within the limiting shell 19, each track 23 is fitted with a spring 24. The spring 24 is in a compressed state, so the spring 24 will return to its elongated state and provide a force to resist the limiting plate 21, ensuring that the limiting rod 22 is stably inserted into the processing cylinder 2. When the limiting plate 21 is not manually pulled, the working motor 5 is a low-speed motor of a conventional sludge dewatering machine. Its force to drive the rotation of the processing cylinder 2 will not cause the limiting plate 21 to move on the inner wall of the limiting shell 19, and the spring 24 will not be compressed.

[0029] Finally, in practical applications, the treatment cylinder 2 may rotate due to the interaction between the sludge inside and the spiral pusher plate 7. However, the treatment cylinder 2 will not rotate very quickly. The screen plates 3 in the three openings on it will have different blockage conditions. Some will be severely blocked, while others may not be blocked. Three rotating rods 32 are fixedly welded to the surface of the treatment cylinder 2. The operator can rotate the treatment cylinder 2 by rotating the rotating rods 32 so that the unblocked screen plates 3 are at the bottom. In this way, the sewage desludge removal work can still be carried out. Then, the other screen plates 3 can be disassembled and maintained, and then the maintained screen plates 3 can be installed. This process can be repeated so that each screen plate 3 can be cleared and maintained without stopping the machine. Furthermore, the linear drive force of the working motor 5 does not directly act on the treatment cylinder 2. Therefore, there is no rigid transmission structure to drive the treatment cylinder 2 to rotate. So, when the operator is performing the above-mentioned maintenance work on the screen plates 3, there is no risk of being pulled into the treatment cylinder 2.

[0030] In use, the sludge pump 8 draws sludge and feeds it into the treatment cylinder 2. The working motor 5 operates, driving the spiral pusher plate 7 to rotate via the working shaft 6. The spiral pusher plate 7 transports the sludge from the treatment cylinder 2. The water in the sludge falls into the water tank 26 through the water outlet 4. As the transport continues, the sludge is discharged from the left opening of the treatment cylinder 2 and enters the sludge box 25. The placement of the sludge box 25 facilitates removal and emptying of the sludge. When the screen plate 3 needs to be disassembled, the limiting plate 21 is engaged. The limiting plate 21 slides on the surface of the track 23, compressing the spring 24. The limiting plate 21 then drives the limiting rod 22 to disengage from the treatment cylinder 2. Then, the limiting shell 19 is pulled, causing the positioning rod 20 to disengage from the stabilizing ring 17. The limiting shell 19 then drives the insertion rod 15 to disengage from the fixing plate 14. In this way, the screen plate 3 can be removed from the opening on the surface of the treatment cylinder 2 for unclogging and maintenance.
