Description

Technical Field

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

[0002] Sludge generated during river dredging projects requires dewatering to reduce its volume and facilitate subsequent disposal. Belt filter presses are widely used for mechanical dewatering of river sludge due to their advantages of continuous operation and high throughput. In a belt filter press, the sludge is evenly spread between two annular filter cloths and moves synchronously with the filter belt, sequentially passing through a gravity dewatering zone, a wedge-shaped pre-compression zone, and a high-pressure extrusion zone composed of multiple rollers. In the high-pressure extrusion zone, the sludge interlayer wraps around the surface of the rollers along with the filter cloth. The linear pressure and shear force applied by the rollers forcefully squeeze out the interstitial water in the sludge, achieving deep dewatering.

[0003] During high-pressure extrusion, sludge is prone to lateral overflow from both sides of the filter cloth. When the sludge interlayer passes through the curved surface of the roller with the filter cloth, under the action of huge radial pressure, the sludge tends to migrate to the area with relatively low pressure. Existing technology usually uses a thickened layer sewn on the edge of the filter cloth to enhance the sealing of the edge, but it lacks active limiting constraint on the edge of the filter cloth in the high-pressure area, resulting in insufficient sealing. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a river sludge dewatering device to solve the issue of filter cloth effectively sealing off lateral sludge overflow in the high-pressure zone.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a river sludge dewatering device, including a drum and a fixed base, further including a support plate, pressure-applying components, a limiting mechanism, and a traction mechanism. The support plate is fixedly installed at both ends of the drum, and the support plate is rotatably connected to the fixed base. The pressure-applying components are in multiple sets and are slidably installed inside the support plate. The limiting mechanism is rotatably installed on the side of the support plate near the fixed base, and the limiting end of the limiting mechanism is in contact with both sides of the arrayed pressure-applying components. The traction mechanism is located on the side of the support plate near the fixed base, and the rotating end of the traction mechanism is in contact with the limiting mechanism. The moving end of the traction mechanism is connected to the moving end of the pressure-applying components.

[0006] The support plate includes a plate body, a sliding groove, and a rotating shaft. One side of the plate body is fixedly connected to one end of the roller. The surface of the plate body is provided with a sliding groove, and the two ends of the sliding groove are provided with placement grooves. The other side of the plate body is fixedly connected to the rotating shaft, and the free end of the rotating shaft is rotatably connected to the fixed seat.

[0007] The pressure-applying component includes a sliding sleeve, a rod, a slider, a pressure plate, and a connecting rod. The sliding sleeve is slidably installed inside the support plate. The rod passes through both sides of the sliding sleeve and fits against the inner wall of the sliding groove. The slider is slidably sleeved on the surface of the rod and located inside the sliding sleeve. The pressure plate is fixedly installed at one end of the slider, and the connecting rod is fixedly installed at the other end of the slider.

[0008] The pressure plate is located on the side of the slider near the support plate and is fixed by bolts or screws. The pressure plate is arc-shaped and is set in a corresponding manner to the support plate.

[0009] The limiting mechanism includes a transmission gear and a limiting plate. The transmission gear is rotatably mounted on one side of the support plate, and a connecting plate is fixedly mounted on the surface of the transmission gear. The limiting plate is rotatably mounted on the free end of the connecting plate, and the limiting plate is located inside the slide groove and fits against the pressure-applying component.

[0010] The limiting mechanism also includes a transmission toothed plate, a groove, and a handle. The transmission toothed plate is slidably mounted on the surface of the support plate and is meshed with the transmission gear. A groove is provided on the top of the transmission toothed plate, and the handle is fixedly mounted on the surface of the transmission toothed plate.

[0011] The traction mechanism includes a top plate and a first screw. The top plate is fixedly installed on the surface of the support plate, and the first screw is threadedly installed on the surface of the top plate.

[0012] The traction mechanism also includes a second screw, a traction block, and a traction cable. The second screw is rotatably mounted on the surface of the top plate, and the traction block is threaded onto the surface of the second screw. The traction block and the rotating shaft are slidably connected. One end of the traction cable passes through the surface of the rotating shaft and is connected to the traction block, and the other end of the traction cable is connected to the moving end of the pressure-applying component.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes the second screw to drive the traction block to slide inside the rotating shaft, causing the traction block to pull the traction cable. The traction cable then drives the connected rod to move towards the rotating shaft. The slider slides on the surface of the rod, and the sliding sleeve is driven to press the edge of the filter cloth tightly against both ends of the support plate. This improves the sealing effect of the filter cloth edge in the high-pressure zone, preventing accidental overflow along the filter cloth edge when sludge is squeezed and dehydrated by the support plate. The sliding sleeve and rod slide within the groove, allowing for easy control of the number of pressure-applying components arranged inside the groove, adapting to changes in the contact edge length between the filter cloth and the support plate surface. Pulling the handle moves the transmission gear plate, causing the transmission gear meshing with the transmission gear plate to rotate. This causes the limiting plate on the surface of the transmission gear to clamp and limit the multiple sets of pressure-applying components. Tightening the first screw until it enters the groove limits and fixes the sliding of the transmission gear plate. Attached Figure Description

A device for adjusting the position of the support plate 2 is connected to the fixed base 3. A device for driving the support plate 2 to rotate can be installed on the surface of the fixed base 3 or rotate with the movement of the filter cloth. Multiple sets of pressure-applying components 4 are slidably installed inside the support plate 2. The limiting mechanism 5 is rotatably installed on the side of the support plate 2 near the fixed base 3, and the limiting end of the limiting mechanism 5 is in contact with both sides of the arrayed pressure-applying components 4. The traction mechanism 6 is located on the side of the support plate 2 near the fixed base 3, and the rotating end of the traction mechanism 6 is in contact with the limiting mechanism 5. The moving end of the traction mechanism 6 is connected to the moving end of the pressure-applying components 4.

[0024] Specifically, the sludge is squeezed and dewatered by the roller 1 and the filter cloth. The edges of the filter cloth at both ends of the support plate 2 are pressed by the pressure member 4. The pressure member 4 is pressed and limited by the limiting mechanism 5. The limiting mechanism 5 is limited and fixed by the traction mechanism 6, and the pressure member 4 is pulled so that the pressure member 4 is in close contact with the filter cloth on the surface of the support plate 2.

[0025] The support plate 2 includes a plate body 201, a sliding groove 202 and a rotating shaft 203. One side of the plate body 201 is fixedly connected to one end of the roller 1. The sliding groove 202 is provided on the surface of the plate body 201. Placement slots are provided at both ends of the sliding groove 202. The other side of the plate body 201 is fixedly connected to the rotating shaft 203. The free end of the rotating shaft 203 is rotatably connected to the fixed seat 3.

[0026] Specifically, the support plate 2 is supported by the plate body 201 and the rotating shaft 203 to rotate on the surface of the fixed base 3. The pressure application component 4 is accommodated by the slide groove 202 and slides inside it. The placement groove facilitates the addition of the pressure application component 4 into the slide groove 202 or the removal of the pressure application component 4 from the slide groove 202.

[0027] The pressure-applying component 4 includes a sliding sleeve 401, a rod 402, a slider 403, a pressure plate 404, and a connecting rod 405. The sliding sleeve 401 is slidably installed inside the slide groove 202. The rod 402 passes through both sides of the sliding sleeve 401 and fits against the inner wall of the slide groove 202. The rod 402 on the outside of the sliding sleeve 401 has a circular cross-section, and the rod 402 on the inside of the sliding sleeve 401 has a rectangular cross-section. The slider 403 is slidably sleeved on the surface of the rod 402 and located inside the sliding sleeve 401. The pressure plate 404 is fixedly installed at one end of the slider 403, and the connecting rod 405 is fixedly installed at the other end of the slider 403.

[0028] Specifically, by sliding the sliding sleeve 401 inside the sliding groove 202, the length of the multiple sets of pressure plates 404 arranged and spliced ​​is adjusted. By sliding the slider 403 on the rectangular surface of the rod 402, the pressure plates 404 are driven to press the filter cloth at both ends of the support plate 2 surface to prevent the sludge from overflowing. Through the connection of the connecting rod 405 and the traction steel cable 605, the multiple sets of pressure plates 404 are synchronously adjusted by the traction mechanism 6.

[0029] The pressure plate 404 is located on the side of the slider 403 near the support plate 2 and is fixed by bolts or screws. The pressure plate 404 is arc-shaped and is correspondingly set to the support plate 2.

[0030] Specifically, based on the overall thickness of the sludge wrapped in the filter cloth and the thickness of the filter cloth edge, a pressure plate 404 of appropriate size and shape can be selected to limit and press it.

[0031] The limiting mechanism 5 includes a transmission gear 501 and a limiting plate 502. The transmission gear 501 is slidably sleeved on the surface of the rotating shaft 203. A connecting plate is fixedly installed on the surface of the transmission gear 501. The limiting plate 502 is rotatably installed on the free end of the connecting plate. The limiting plate 502 is located inside the sliding groove 202 and is in contact with the pressure member 4. There are two sets of transmission gears 501. One set of transmission gears 501 is located between the other set of transmission gears 501 and the disc body 201.

[0032] Specifically, by the alternating rotation of two sets of transmission gears 501 on the surface of the rotating shaft 203, the limiting plate 502 on its surface is driven to approach the two sides of the multiple sets of pressure members 4 inside the slide groove 202, clamping and fixing them to limit the position of the pressure members 4.

[0033] The limiting mechanism 5 also includes a transmission toothed plate 503, a groove 504, and a handle 505. The transmission toothed plate 503 is slidably mounted on the surface of the disc body 201. The transmission toothed plate 503 is meshed with the transmission gear 501. The top of the transmission toothed plate 503 is provided with a groove 504. The inner wall of the groove 504 is provided with an anti-slip layer. The handle 505 is fixedly mounted on the surface of the transmission toothed plate 503. There are two sets of transmission toothed plates 503. One set of transmission toothed plates 503 is located between the other set of transmission toothed plates 503 and the disc body 201, and the other set of transmission toothed plates 503 is slidably mounted on the surface of the first set of transmission toothed plates 503.

[0034] Specifically, by pulling the two sets of transmission gear plates 503 with the handle 505, the transmission gear plates 503 drive the transmission gear 501 that meshes with them to rotate. The sliding of the transmission gear plates 503 is limited and fixed by the tight contact between the groove 504 and the first screw 602.

[0035] The traction mechanism 6 includes a top plate 601 and a first screw 602. The top plate 601 is fixedly installed on the surface of the disc 201, and the first screw 602 is threadedly installed on the surface of the top plate 601, with its bottom end inserted into the interior of the groove 504.

[0036] Specifically, the first screw 602 rotates at the top plate 601, causing the bottom end of the first screw 602 to insert into the groove 504, and relying on its frictional resistance to prevent the transmission gear plate 503 from sliding freely.

[0037] The traction mechanism 6 also includes a second screw 603, a traction block 604, and a traction cable 605. The second screw 603 is rotatably mounted on the surface of the top plate 601. The traction block 604 is threaded onto the surface of the second screw 603. The traction block 604 is slidably inserted into the rotating shaft 203. One end of the traction cable 605 passes through the surface of the rotating shaft 203 and is connected to the traction block 604. The other end of the traction cable 605 is connected to the connecting rod 405.

[0038] Specifically, the second screw 603 rotates at the top plate 601, causing the second screw 603 to drive the traction block 604 to move up and down along its surface. The traction block 604 slides inside the rotating shaft 203, pulling the connecting rod 405 connected to the traction cable 605 to move accordingly.

[0039] In summary: When using this utility model, if the operator needs to drive the support plate 2 to rotate and dewater the sludge wrapped in the filter cloth, the number of pressure-applying components 4 inside the placement groove at the slide 202 can be increased or decreased according to the length of the filter cloth edge that is in contact with the surface of the support plate 2. This pushes multiple sets of pressure-applying components 4 to slide and arrange inside the slide 202, so that the pressure plate 404 is aligned with the filter cloth. Pulling the two sets of handles 505 drives the transmission gear plate 503 to slide, which in turn drives the transmission gear 501 meshing with it to rotate on the surface of the rotating shaft 203. The transmission gear 501 drives the limiting plate 502 to clamp and limit the multiple sets of pressure-applying components 4 on both sides. Twisting The first screw 602 rotates at the top plate 601, causing the first screw 602 to insert into the groove 504 to limit and fix the transmission gear plate 503. Tightening the second screw 603 drives the traction block 604 to move along its surface, causing the traction block 604 to slide inside the rotating shaft 203. The traction block 604 drives the connecting rod 405 connected to the traction steel cable 605 to move. The connecting rod 405 drives the slider 403 to slide on the surface of the rod body 402. The slider 403 drives the pressure plate 404 to press the edges of the filter cloth at both ends of the surface of the support plate 2, so as to prevent the sludge from overflowing from the edges of the filter cloth during the sludge dewatering process.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
