Description

Technical Field

[0001] This utility model relates to the field of dredged soil dewatering, and more specifically, to a rapid dewatering device for dredged soil in waterways. Background Technology

[0002] In waterway dredging, environmental dredging and other projects, dredged soil has a high water content (usually over 70%) and strong viscosity. It needs to be dehydrated before it can be transported in reduced quantities and utilized as a resource. In the dehydration process, dredged soil is usually first squeezed to complete the initial dehydration operation.

[0003] A search revealed Chinese patent CN204675982U, which discloses a dredged soil dewatering and solidification device. The device includes a dewatering chamber and a mixing chamber, with the dewatering chamber installed above the mixing chamber and a conveying pipe connecting them. The dewatering chamber contains a partition with an opening on one side, and a first pusher plate and a second pusher plate symmetrically arranged on both sides. A feed pipe is installed above the partition. A drainage channel is provided within the partition. A feeding port is located above the mixing chamber, and a mixing plate is installed inside. Compared to existing technologies, this invention has the following advantages: through a rational structural design, the dredged soil is dewatered by extrusion, the entire process is automated, and the extruded blocks are crushed and mixed with a solidifying agent. This device offers good dewatering effect, high speed, and a high degree of automation, making it suitable for widespread use.

[0004] However, existing technologies still have certain shortcomings when used. For example, in the process of squeezing and dewatering dredged soil, existing technologies mainly rely on two push plates to squeeze and dewater the dredged soil. Although this method can squeeze out the water in the dredged soil, it will also cause the dredged soil to clump together, and the water cannot be effectively discharged. As a result, the dredged soil cannot achieve a good dewatering effect when squeezing and dewatering. Utility Model Content

[0005] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide a rapid dewatering device for dredged soil in waterways, which can improve the dewatering effect by cutting the dredged soil during the compression dewatering process to avoid clumping.

[0006] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0007] A rapid dewatering device for dredged soil in waterways includes a dewatering tank with a downward opening. A feed pipe is installed on the top of the dewatering tank, and a receiving plate is fixedly installed at the bottom of the inner cavity of the dewatering tank. A discharge port is reserved between the dewatering tank and the receiving plate. Extrusion mechanisms are provided on both sides of the inner cavity of the dewatering tank. A driving mechanism is provided on the dewatering tank relative to the extrusion mechanism, and a drainage mechanism is provided on the dewatering tank relative to the receiving plate.

[0008] Furthermore, the extrusion mechanism includes an extrusion plate disposed on the inner wall of the dehydration tank. Elastic components are disposed at each of the four corners of one side of the extrusion plate. Multiple cutting components are disposed on the surface of the elastic components. A fixing component is disposed at the end of the elastic component relative to the position of the cutting components.

[0009] Furthermore, the elastic component includes a guide post fixedly installed on one side of the extrusion plate, and a plurality of gaskets, springs, and telescopic sleeves sleeved on the surface of the guide post. The two ends of the springs and the telescopic sleeves are respectively fixedly connected to the inner sides of two adjacent gaskets.

[0010] Furthermore, the cutting component includes multiple mounting frames, with a screen fixedly mounted on the inner wall of each mounting frame. Insertion slots are provided on the sides of each mounting frame relative to the multiple guide posts. The mounting frame is fitted onto the surface of the guide posts through the insertion slots. Two gaskets are located inside adjacent mounting frames. The aperture values ​​of the multiple insertion slots gradually decrease along the direction closer to the extrusion plate.

[0011] Furthermore, the fixing component includes a threaded groove formed at one end of the guide post and a limiting piece disposed at the end of the guide post, the limiting piece being screwed into the threaded groove by a fixing bolt.

[0012] Furthermore, the driving mechanism includes two electric push rods installed on both sides of the dehydration tank. The telescopic ends of the two electric push rods both penetrate the interior of the dehydration tank. The telescopic ends of the electric push rods are fixedly connected to the extrusion plate. A fixing frame fixedly connected to the electric push rods is fixedly installed on the surface of the dehydration tank. A controller is fixedly installed on the surface of the dehydration tank.

[0013] Furthermore, the drainage mechanism includes a water receiving groove opened on the top of the receiving plate and a drainage groove opened at the bottom of the inner cavity of the water receiving groove. The extension end of the drainage groove passes through the outside of the dehydration tank, and a drainage pipe is fixedly sleeved on the extension end of the drainage groove. A filter cloth is fixedly installed on the inner wall of the water receiving groove.

[0014] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) This solution utilizes a squeezing mechanism to dewater the dredged soil during the mutual squeezing of two squeezing plates. At the same time, by setting a cutting component, the dredged soil can be cut during the squeezing process to avoid clumping. By setting an elastic component, the squeezing force can be buffered to avoid local pressure surges that could cause blockage of the insertion slot. At the same time, the pressure can be transmitted more evenly to the surface of the dredged soil to assist in the infiltration and discharge of water. Meanwhile, the elastic extension and contraction of the spring can cause the insertion slot to vibrate slightly during the squeezing and resetting process, which can shake off the fine soil particles in the gaps of the insertion slot and reduce the probability of dredged soil agglomeration and clumping. This solves the problem of poor dewatering effect in the prior art.

[0015] (2) This scheme utilizes a drive mechanism to enable two extrusion mechanisms to move, thereby extruding and feeding the dredged soil. By gradually reducing the aperture value of multiple insertion slots along the direction close to the extrusion plate, it is possible to cut the clumps through the outer insertion slots and filter water through the inner insertion slots. By setting an installation frame, the strength of the cutting components can be increased and the risk of damage can be reduced. Attached Figure Description

[0021] Example 1: Please see Figure 1-5 A rapid dewatering device for dredged soil includes a dewatering tank 1 with a downward opening. A feed pipe 2 is installed on the top of the dewatering tank 1. A receiving plate 3 is fixedly installed at the bottom of the inner cavity of the dewatering tank 1. A discharge port 4 is reserved between the dewatering tank 1 and the receiving plate 3. Extrusion mechanisms 5 are provided on both sides of the inner cavity of the dewatering tank 1. A driving mechanism 6 is provided on the dewatering tank 1 relative to the extrusion mechanisms 5. A drainage mechanism 7 is provided on the dewatering tank 1 relative to the receiving plate 3. During dewatering of the dredged soil, the dredged soil is introduced through the feed pipe 2. The dredged soil is placed in the dewatering tank 1, and then the extrusion mechanism 5 is driven by the drive mechanism 6, so that the two extrusion mechanisms 5 move toward the position of the dredged soil and extrude it. This allows the dredged soil to be extruded and cut. The water extruded is discharged through the drainage mechanism 7, and the dewatered dredged soil is discharged through the discharge port 4 for further processing. Since this is prior art, it is not described in detail in this technical solution. For details, please refer to the dredged soil dewatering and solidification device disclosed in the authorization announcement number CN204675982U.

[0022] Preferably, the extrusion mechanism 5 includes an extrusion plate 51 disposed on the inner wall of the dewatering tank 1. Each of the four corners of one side of the extrusion plate 51 is provided with an elastic member 52. The surface of the elastic member 52 is provided with a plurality of cutting members 53. The end of the elastic member 52 is provided with a fixing member 54 at a position relative to the cutting member 53. By setting the extrusion plate 51, the dredged soil can be extruded. By setting the cutting members 53, the dredged soil can be cut during the extrusion process to avoid clumping. By setting the elastic member 52, the extrusion force can be buffered to avoid local pressure surges that could cause blockage of the insertion groove 533. At the same time, the pressure can be transmitted more evenly to the surface of the dredged soil to assist in water penetration and discharge. By setting the fixing member 54, it is convenient to limit or disassemble and replace the cutting member 53.

[0023] The elastic component 52 includes a guide post 521 fixedly installed on one side of the extrusion plate 51, which can extend and retract on the guide post 521 when the cutting component 53 is under force, as well as multiple gaskets 522, springs 523, and telescopic sleeves 524 sleeved on the surface of the guide post 521. The two ends of the springs 523 and the telescopic sleeves 524 are respectively fixedly connected to the inner side of two adjacent gaskets 522. By setting the springs 523, the extrusion force can be buffered to avoid the cutting component 53 from being blocked due to a sudden increase in local pressure. At the same time, the pressure can be transmitted to the surface of the dredged soil more evenly to assist in the infiltration and discharge of water. By setting the telescopic sleeves 524, the dredged soil can be prevented from blocking the springs 523, thus playing a protective role.

[0024] It should be noted that the cutting component 53 includes multiple mounting frames 531. A screen 532 is fixedly installed on the inner wall of the mounting frame 531. Insertion slots 533 are opened on the side of the mounting frame 531 relative to the multiple guide posts 521. The mounting frame 531 is fitted onto the surface of the guide post 521 through the insertion slots 533. Two gaskets 522 are located on the inner side of two adjacent mounting frames 531. The aperture value of the multiple insertion slots 533 gradually decreases along the direction close to the extrusion plate 51. The dredged soil can be cut through the insertion slots 533. The strength of the insertion slots 533 can be increased by setting the mounting frames 531. The mounting frame 532 can be used to fit the mounting frame 531 onto the guide post 521. The aperture value of the multiple insertion slots 533 gradually decreases along the direction close to the extrusion plate 51, which can achieve the cutting of clumps through the outer insertion slots 533 and the filtering of water through the inner insertion slots 533.

[0025] It should also be noted that the fixing component 54 includes a threaded groove 541 opened at one end of the guide post 521, and a limiting piece 542 disposed at the end of the guide post 521. The limiting piece 542 is screwed into the threaded groove 541 by a fixing bolt 543. By placing the limiting piece 542 at the end of the guide post 521 and inserting the fixing bolt 543 into the threaded groove 541, the guide post 521 can be limited, preventing the cutting component 53 from detaching from the guide post 521.

[0026] Furthermore, the drive mechanism 6 includes two electric push rods 61 installed on both sides of the dewatering tank 1. The telescopic ends of the two electric push rods 61 extend through the interior of the dewatering tank 1. The telescopic ends of the electric push rods 61 are fixedly connected to the extrusion plate 51. A fixed frame 62, which is fixedly connected to the electric push rods 61, is fixedly installed on the surface of the dewatering tank 1. A controller 63 is fixedly installed on the surface of the dewatering tank 1. During extrusion, the controller 63 causes the two electric push rods 61 to drive the extrusion mechanism 5 to move in opposite directions, which can extrude the dredged soil. After the dredged soil is extruded, the electric push rod 61 on the side closer to the discharge port 4 retracts to expose the discharge port 4. The electric push rod 61 on the side farther away from the discharge port 4 drives the extrusion mechanism 5 to continue moving, thereby pushing the dredged soil to the discharge port 4 for discharge.

[0027] In addition, the drainage mechanism 7 includes a water receiving trough 71 opened on the top of the receiving plate 3, and a drainage trough 72 opened at the bottom of the inner cavity of the water receiving trough 71. The extension end of the drainage trough 72 passes through the outside of the dewatering tank 1. A drainage pipe 73 is fixedly connected to the extension end of the drainage trough 72. A filter cloth 74 is fixedly installed on the inner wall of the water receiving trough 71. When the squeezing mechanism 5 squeezes the dredged soil, the squeezed water is discharged through the water receiving trough 71, the drainage trough 72 and the drainage pipe 73. By setting the filter cloth 74, the dredged soil can be intercepted and prevented from being discharged with the sewage.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
