Description

Technical Field

[0001] This invention belongs to the field of river dredging technology, specifically a river dredging and transfer device. Background Technology

[0002] Currently, river dredging involves using mechanical equipment to remove silt accumulated at the bottom of the riverbed, which is then transported away to clear the waterway. However, freshly removed silt contains a large amount of water, increasing its weight and viscosity, making transportation inconvenient and inefficient. To mitigate these issues, existing technologies typically dehydrate the freshly removed silt, reducing its water content and making transportation more convenient while effectively reducing energy consumption.

[0003] The existing river dredging and transfer device, with publication number CN223342556U, separates silt from water by pushing a squeezing plate through a filter steel mesh. However, during the process of the silt being pushed to the right and pressurized by the squeezing plate, continuous pressure is applied to the filter steel mesh on the right side. Over time, this causes the filter steel mesh to deform concavely to the right. At this point, a large gap will form between the brush on the mounting slot and the outer surface of the filter steel mesh, resulting in the brush being unable to clean the silt inside the mesh openings. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem that existing filter steel mesh is prone to concave deformation due to unilateral pressure, making mesh cleaning difficult, the technical solution adopted in this invention is: a river dredging and transfer device, comprising a dredging box, a pressurizing component, a backflushing component, and a traction component. The pressurizing component is inserted into the left side of the inner wall of the dredging box, the backflushing component is located at the axis on the right side of the dredging box, and the left end of the traction component is inserted into the axis on the right side of the backflushing component. The sludge removal box includes a transfer box cylinder, a feeding funnel, a threaded guide cylinder, and a filter steel mesh; The outer surface of the filter steel mesh is sleeved with the right side of the inner wall of the transfer box cylinder. The transfer box cylinder limits and fixes the filter steel mesh through its slot. A feeding groove is opened at the bottom of the inner cavity of the transfer box cylinder. The threaded guide cylinder is inserted into the axis on the left side of the inner cavity of the transfer box cylinder. The bottom of the feeding funnel is inserted into the top of the inner cavity of the transfer box cylinder. The backflush component includes a faceplate, a transverse strip box, and a containerized water pump; The outer surface of the bonding plate is pressed against the outer surface of the filter steel mesh on the side away from the threaded guide cylinder. The shape of the bonding plate is as follows: Figure 4As shown, its outer surface can fit against the right side of the filter steel mesh. The middle part of the inner cavity of the bonding plate is connected to the outer surface of the transverse bar box through a cross-cut groove. The inner cavity of the transverse bar box is uniformly provided with a collection spray pipe. The end of the collection spray pipe away from the filter steel mesh is inserted into the inner cavity of the collection water pump. The two ends of the collection water pump are symmetrically inserted with backflush water pipes. After the traction component pushes the bonding plate towards the side of the filter steel mesh and pressurizes it, the bonding plate fits against the filter steel mesh. The collection water pump sprays water in reverse to the filter steel mesh through the collection spray pipe. The traction component drives the bonding plate to rotate, so that the spray range of the collection spray pipe covers the entire outer surface of the filter steel mesh.

[0005] Furthermore, the traction component includes: A torque motor, wherein a support frame is sleeved on the outer surface of the torque motor housing, and a closed outer disc is inserted into the outer surface of the torque motor shaft; The control push cylinder has a connecting rod slidably connected to its inner wall axis via rollers. The control push cylinder can drive the connecting rod to slide through the rollers driven by an internal motor, thereby achieving the effect of traction and sliding of the bonding plate. The outer surface of the control push cylinder is inserted into the outer surface of the closed outer disk. The end of the connecting rod away from the control push cylinder is inserted into the side of the outer surface of the bonding plate away from the filter steel mesh. When the torque motor drives the axis of the closed outer disk to rotate, the control push cylinder and the connecting rod assembled in the closed outer disk will drive the bonding plate on the left side to rotate.

[0006] Furthermore, the traction component also includes: The inner rotating disc has its outer surface rotatably connected to the inner cavity of the closed outer disc via a rotating groove. Symmetrical through-holes are provided on both sides of the inner cavity of the inner rotating disc. The end of the backflush water pipe away from the pump extends to the outside of the closed outer disc through the through-hole. When the axis of the closed outer disc rotates, its outer part will not rotate synchronously due to the rotation of the inner rotating disc. An external water supply device is provided, wherein the outer surface of the external water supply device is inserted into the side of the outer surface of the closed outer disc away from the filter steel mesh, and the end of the backflush water pipe away from the container water pump is inserted into the inner cavity of the external water supply device.

[0007] Furthermore, it also includes: The filter sleeve has its left end inserted into the right end of the adapter box, and its right end rotatably connected to the outer surface of the closed outer disc. The outer surface of the face plate is slidably connected to the inner wall of the filter sleeve, and the outer part of the closed outer disc is sleeved with the right end of the filter sleeve, thereby maintaining the stability of the device cylinder. A sealing component, wherein the sealing components are symmetrically arranged on the front and rear sides of the outer surface of the adapter box cylinder; A sludge holding frame is positioned directly below the feeding chute; A water-holding frame is positioned directly below the filter sleeve.

[0008] Furthermore, the pressurizing component includes: A pressure pusher plate, the outer surface of which is slidably connected to the inner wall of the transfer box cylinder; A drive motor is provided, and a threaded rod is inserted into the outer surface of the drive motor shaft. The outer surface of the threaded rod is threadedly connected to the inner wall of the threaded guide cylinder. The right end of the threaded rod is inserted into the center of the outer surface of the pressure push plate. The drive motor rotates the threaded rod clockwise, causing the threaded rod to spirally push the pressure push plate to the right along the threaded guide cylinder. The direct push guide rod is symmetrically inserted into the left side of the outer surface of the adapter box. The end of the direct push guide rod away from the adapter box is inserted into the outer surface of the drive motor housing through a connecting plate. The direct push guide rod has an interlocking rod core structure inside, which ensures that the direct push guide rod as a whole can only undergo lateral compression deformation and cannot be twisted, thereby restricting the drive motor from rotating.

[0009] Furthermore, the pressurizing component also includes: A strip scraper, the left side of which is inserted into the right side of the outer surface of the pressure pusher, the outer surface of which is slidably connected to the inner wall of the transfer box, and the two sides of the strip scraper are relatively sharp and fit against the inner wall of the transfer box. A pressure end rod, the outer surface of which is inserted into the inner cavity of the strip scraper, and the right end of which extends to the outside of the strip scraper; The pressure controller is evenly distributed on the left side of the outer surface of the pressure push plate, and the inner cavity of the pressure controller is connected to the left end of the pressure rod through a connecting wire. When the pressure controller is triggered, it can control the drive motor to stop working.

[0010] Furthermore, the sealing component includes: A side fixing plate, wherein through openings are symmetrically provided on both sides of the inner cavity of the side fixing plate; A compression push rod is symmetrically inserted into both sides of the inner cavity of the side fixing plate through a through-hole. One end of the compression push rod is connected to a control air pump, and the other end of the compression push rod is connected to an arc-shaped sealing plate. After the arc-shaped sealing plates on the front and rear sides are joined together, the feeding groove at the bottom of the transfer box can be completely sealed. The outer surface of the control air pump is inserted into the outer surface of the side fixing plate, and the inner cavity of the arc-shaped sealing plate is provided with a pressure-sensing inner plate.

[0011] Furthermore, the sealing component also includes: The lower blow-jet box has its outer surface inserted into the upper part of the inner cavity of the side fixing plate, and the bottom of the lower blow-jet box is evenly provided with air jets. A heat dissipation baffle, the outer surface of which is inserted into the top of the inner cavity of the fixed plate.

[0012] The beneficial effects of this invention are as follows: 1. This device can remove wastewater from sludge, achieving dewatering treatment of the sludge. After each sludge filtration operation, the pressure plate applies reverse pressure to the right side of the filter mesh. This corrects the filter mesh before it undergoes significant irreversible deformation, preventing the left side of the mesh from being continuously pressured and causing concave deformation to the right. This ensures uniform mesh size distribution and effective wastewater filtration.

[0013] 2. The backflushing component clears the sludge accumulated in the filter mesh by spraying water from right to left on the right side of the filter mesh. The pressure plate rotates along the outer surface of the filter mesh, so the spray range of the nozzle can cover the entire outer surface of the filter mesh, avoiding dead corners where sludge cannot be cleared. Furthermore, the pressure plate is in close contact with the outer surface of the filter mesh, so the water pumped by the nozzle can generate a strong impact on the filter mesh. This prevents water leakage due to gaps between the nozzle and the filter mesh, which would weaken the impact effect.

[0014] 3. The pressurizing component concentrates the sludge inside the transfer box on the right side. As the strip scraper slides and rotates with the pressurizing push plate, it can scrape off the sludge adhering to the inner wall of the transfer box through the side, reducing the amount of sludge residue inside the transfer box. When the right end of the strip scraper is about to contact the filter steel mesh, the pressure end rod will squeeze the filter steel mesh in advance, thereby triggering the pressure sensor controller to stop the drive motor from pushing. This intelligently controls the pushing amount of the pressurizing push plate, avoiding the problem of excessive pressure on the right side of the filter steel mesh due to excessive pressure.

[0015] 4. The arc-shaped sealing plate at the closure monitors the weight of the sludge accumulated inside the transfer box via an internal pressure-sensing plate. Once the predetermined value of the pressure-sensing plate is reached, the sludge can be automatically discharged. This not only makes the discharge method more convenient but also avoids the problem of excessive sludge accumulation inside the transfer box, exceeding the load of the cylinder and affecting the operation of the internal mechanism. After the arc-shaped sealing plates on both sides are opened, when the arc-shaped sealing plates move to the position directly below the lower blow-jet box, the lower blow-jet box blows air onto the concave surface of the arc-shaped sealing plates through the jet nozzles. This causes the sludge, wastewater, and other impurities attached to the concave surface of the arc-shaped sealing plates to be blown down along the inner wall of the concave surface of the arc-shaped sealing plates into the sludge collection frame, thereby reducing the amount of sludge residue on the concave surface of the arc-shaped sealing plates.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a river dredging and transfer device, including a dredging box 1, a pressurizing component 2, a backflushing component 3 and a traction component 5. The pressurizing component 2 is inserted into the left side of the inner wall of the dredging box 1, the backflushing component 3 is set at the axis on the right side of the dredging box 1, and the left end of the traction component 5 is inserted into the axis on the right side of the backflushing component 3. The sludge removal box 1 includes a transfer box cylinder 11, a feeding funnel 14, a threaded guide cylinder 15, and a filter steel mesh 13; The outer surface of the filter steel mesh 13 is sleeved with the right side of the inner wall of the transfer box cylinder 11. The transfer box cylinder 11 limits and fixes the filter steel mesh 13 through its slot. A feeding groove 12 is opened at the bottom of the inner cavity of the transfer box cylinder 11. The threaded guide cylinder 15 is inserted into the axis on the left side of the inner cavity of the transfer box cylinder 11. The bottom of the feeding funnel 14 is inserted into the top of the inner cavity of the transfer box cylinder 11. Backflush component 3 includes a faceplate pressure plate 31, a transverse strip box 32, and a containerized water pump 34; The outer surface of the bonding plate 31 is pressed against the outer surface of the filter steel mesh 13 on the side away from the threaded guide cylinder 15. The shape of the bonding plate 31 is as follows: Figure 4 As shown, its outer surface can fit against the right side of the filter steel mesh 13. The middle part of the inner cavity of the bonding plate 31 is connected to the outer surface of the transverse bar box 32 through a cross-cut groove. The inner cavity of the transverse bar box 32 is uniformly provided with a collection nozzle 33. The end of the collection nozzle 33 away from the filter steel mesh 13 is inserted into the inner cavity of the collection water pump 34. The two ends of the collection water pump 34 are symmetrically connected with backflush water pipes 35. After the traction component 5 pushes the bonding plate 31 to the side of the filter steel mesh 13 and pressurizes it, the bonding plate 31 fits against the filter steel mesh 13. The collection water pump 34 sprays water in the reverse direction to the filter steel mesh 13 through the collection nozzle 33. The traction component 5 drives the bonding plate 31 to rotate so that the spray range of the collection nozzle 33 covers the entire outer surface of the filter steel mesh 13.

[0020] Traction component 5 includes: A torque motor 51 has a support frame fitted onto the outer surface of its housing, and a closed outer disc 52 inserted into the outer surface of its shaft. The control push cylinder 53 has a roller slidably connected to the shaft center of its inner wall via a connecting rod 54. The control push cylinder 53 can drive the connecting rod 54 to slide through the roller driven by the internal motor, thereby achieving the effect of traction and sliding of the bonding plate 31. The outer surface of the control push cylinder 53 is inserted into the outer surface of the closed outer disk 52. The end of the connecting rod 54 away from the control push cylinder 53 is inserted into the side of the outer surface of the bonding plate 31 away from the filter steel mesh 13. When the torque motor 51 drives the shaft center of the closed outer disk 52 to rotate, the control push cylinder 53 and the connecting rod 54 mounted on the closed outer disk 52 will drive the bonding plate 31 on the left side to rotate.

[0021] The traction component 5 also includes: The inner rotating disk 55 has its outer surface rotatably connected to the inner cavity of the closed outer disk 52 via a rotating groove. Symmetrical through-holes are provided on both sides of the inner cavity of the inner rotating disk 55. The end of the backflush water pipe 35 away from the container water pump 34 extends to the outside of the closed outer disk 52 through the through-hole. When the axis of the closed outer disk 52 rotates, its outer part will not rotate synchronously due to the rotation effect of the inner rotating disk 55. The external water supply device 56 has its outer surface inserted into the outer surface of the closed outer plate 52 on the side away from the filter steel mesh 13, and the backflush water pipe 35 has its end away from the container water pump 34 inserted into the inner cavity of the external water supply device 56.

[0022] A river dredging and transfer device also includes: The left end of the filter sleeve 4 is inserted into the right end of the adapter box 11, the right end of the filter sleeve 4 is rotatably connected to the outer surface of the closed outer plate 52, the outer surface of the face-fitting pressure plate 31 is slidably connected to the inner wall of the filter sleeve 4, and the outer part of the closed outer plate 52 is sleeved with the right end of the filter sleeve 4, thereby making the device cylinder stable. Sealing component 6 is symmetrically arranged on the front and rear sides of the outer surface of the adapter box cylinder 11; The sludge holding frame 7 is located directly below the feeding chute 12; Water-holding frame 8 is located directly below the water filter sleeve 4.

[0023] When processing sludge: The sludge is fed into the transfer box 11 from the upper left feeding hopper 14. If the strip scraper 22 blocks the bottom opening of the feeding hopper 14, the strip scraper 22 can be rotated and the pressure pusher 21 can be rotated to offset the bottom opening of the feeding hopper 14, so that the sludge can be added into the transfer box 11.

[0024] After the sludge accumulates inside the transfer box cylinder 11, the pressurizing component 2 begins to push the pressurizing push plate 21 to the right. At this time, the sludge is squeezed by the pressurizing push plate 21 and the filter steel mesh 13. The wastewater in the sludge is guided through the filter steel mesh 13 to the water filter sleeve 4 on the right side, and finally collected in the water collection frame 8 below. After the sludge is dewatered, it will gather in the part of the transfer box cylinder 11 that is biased to the right. At this time, the feeding slot 12 at the bottom of the transfer box cylinder 11 is opened to feed the sludge into the sludge collection frame 7 below.

[0025] Processing of the filter steel mesh 13: Because the left side of the filter mesh 13 is subjected to siltation and pressure, it tends to deform to the right after each pressurization. At this time, the control push cylinder 53 on the right side pushes the bonding pressure plate 31 to the left by pushing the connecting rod 54, so that the bonding pressure plate 31 squeezes the right side of the filter mesh 13, shaping and correcting the filter mesh 13. Then, the container water pump 34 draws water from the inside of the external water supply unit 56 through the backflush water pipes 35 on both sides, pressurizes it into each container spray pipe 33, and makes the container... The nozzle 33 sprays water in the opposite direction to the filter steel mesh 13 on the left. During the spraying process, the torque motor 51 drives the surface pressure plate 31 to rotate by rotating the closed outer plate 52, so that the spraying area of ​​the nozzle 33 covers the entire filter steel mesh 13. The back-blowing water flow blows the sludge inside the mesh of the filter steel mesh 13 into the interior of the transfer box cylinder 11, achieving the effect of clearing the mesh of the filter steel mesh 13. The water accumulated inside the transfer box cylinder 11 will be diverted to the interior of the water holding frame 8 during the next sludge filtration operation.

[0026] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the pressurizing component 2 includes: The outer surface of the pressure pusher 21 is slidably connected to the inner wall of the transfer box 11. A drive motor 25 has a threaded rod 26 inserted into the outer surface of its shaft. The outer surface of the threaded rod 26 is threadedly connected to the inner wall of the threaded guide cylinder 15. The right end of the threaded rod 26 is inserted into the center of the outer surface of the pressure push plate 21. The drive motor 25 rotates the threaded rod 26 clockwise, causing the threaded rod 26 to spirally push the pressure push plate 21 to the right along the threaded guide cylinder 15. The direct push guide rod 27 is symmetrically inserted into the left side of the outer surface of the adapter box 11. The end of the direct push guide rod 27 away from the adapter box 11 is inserted into the outer surface of the drive motor 25 housing through a connecting plate. The direct push guide rod 27 has an interlocking rod core structure inside, which ensures that the direct push guide rod 27 can only undergo lateral compression deformation and cannot be twisted, thereby restricting the drive motor 25 from rotating.

[0027] The pressurizing component 2 also includes: The left side of the strip scraper 22 is inserted into the right side of the outer surface of the pressure push plate 21. The outer surface of the strip scraper 22 is slidably connected to the inner wall of the transfer box 11. The two side edges of the strip scraper 22 are relatively sharp and are attached to the inner wall of the transfer box 11. The pressure end rod 23 has its outer surface inserted into the inner cavity of the strip scraper 22, and its right end extends to the outside of the strip scraper 22. The pressure controller 24 is evenly distributed on the left side of the outer surface of the pressure push plate 21, and the inner cavity of the pressure controller 24 is connected to the left end of the pressure end rod 23 through a connecting wire. When the pressure controller 24 is triggered, it can control the drive motor 25 to stop working.

[0028] Sealing component 6 includes: The side fixing plate 61 has through openings symmetrically provided on both sides of its inner cavity; Compression push rod 63 is symmetrically inserted into both sides of the inner cavity of the side fixing plate 61 through the through hole. One end of the compression push rod 63 is inserted into the control air pump 62, and the other end of the compression push rod 63 is inserted into the arc-shaped sealing plate 64. After the arc-shaped sealing plates 64 on the front and rear sides are connected, they can completely seal the feeding groove 12 at the bottom of the transfer box cylinder 11. The outer surface of the control air pump 62 is inserted into the outer surface of the side fixing plate 61, and the inner cavity of the arc-shaped sealing plate 64 is provided with a pressure-sensing inner plate 65.

[0029] Sealing component 6 also includes: The lower blow spray box 67 has its outer surface inserted into the upper part of the inner cavity of the side fixing plate 61, and the bottom of the lower blow spray box 67 is evenly provided with air jets 68. Heat dissipation baffle 66, the outer surface of heat dissipation baffle 66 is inserted into the top of the inner cavity of the fixing plate.

[0030] When pressurized component 2 is performing propulsion: The drive motor 25 drives the threaded rod 26 to rotate clockwise at a constant speed, thereby pushing the pressure push plate 21 to the right and keeping the pressure push plate 21 in a rotating state. At this time, the pressure push plate 21 scrapes the sludge inside the transfer box 11 to the right, causing the sludge between the pressure push plate 21 and the filter steel mesh 13 to accumulate. By squeezing the sludge, the wastewater in the sludge is removed. As the strip scraper 22 slides and rotates with the pressure push plate 21, it can scrape the sludge adhering to the inner wall of the transfer box 11 through the side, reducing the sludge residue inside the transfer box 11. When the right end of the strip scraper 22 is about to contact the filter steel mesh 13, the pressure end rod 23 will squeeze the filter steel mesh 13 in advance, thereby triggering the pressure sensor 24, causing the drive motor 25 to stop pushing. Then the drive motor 25 rotates the threaded rod 26 counterclockwise, pulling the pressure push plate 21 to the left, and the single pressure operation of the pressure component 2 ends.

[0031] After being pressurized, the sludge accumulates at the feeding slot 12 of the transfer box cylinder 11. When the amount of sludge is large, the sludge increases the pressure on the pressure-sensitive inner plate 65 inside the lower arc-shaped sealing plate 64. After the pressure-sensitive inner plate 65 reaches the predetermined value, the sludge can be discharged. At this time, the control air pumps 62 on the front and rear side fixing plates 61 pull open the arc-shaped sealing plates 64 on both sides by pressing their respective compression push rods 63. At this time, the sludge inside the transfer box cylinder 11 falls from the feeding slot 12 into the sludge collection frame 7 below. If the sludge is highly viscous, the sludge on the inner wall of the transfer box cylinder 11 can be scraped off by the strip scraper 22 of the pressurizing component 2.

[0032] After the arc-shaped sealing plates 64 on both sides are opened, when the arc-shaped sealing plates 64 move to the position directly below the lower blow-jet box 67, the lower blow-jet box 67 blows air onto the concave surface of the arc-shaped sealing plates 64 through the jet nozzle 68, causing the sludge, wastewater and other impurities attached to the concave surface of the arc-shaped sealing plates 64 to be blown down along the inner wall of the concave surface of the arc-shaped sealing plates 64 into the sludge collection frame 7, thereby reducing the amount of sludge remaining on the concave surface of the arc-shaped sealing plates 64. After the discharge is completed, the arc-shaped sealing plates 64 on both sides are reconnected to close the feeding slot 12 at the bottom of the transfer box cylinder 11.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
