Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and in particular to a dredging equipment for transporting silt through a silt pipeline. Background Technology

[0002] Silt and sediment pipeline transportation and dredging equipment is an important piece of equipment used in water conservancy projects to clean up sediment deposits in water bodies such as rivers, reservoirs, and lakes. It transports sediment from the water body to a designated location through pipelines, thereby achieving the purpose of dredging. Among them, the most commonly used is the mud pump, which is a type of pump equipment specifically designed to transport liquids containing solid particles.

[0003] After the sludge pump is placed at the bottom of the water body, the pump draws the mixture of liquid and solid particles (sludge) into the pump body through the rotation of the impeller, and discharges the sludge from the pump outlet under the action of centrifugal force and transports it to other places through the pipeline. However, since some sludge is quite thick, it is difficult to effectively clean it by relying solely on the impeller of the sludge pump, resulting in less than ideal dredging efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a silt and sand pipeline transportation and dredging device. Utility Model Content

[0005] This utility model provides a silt pipeline transportation and dredging device, which solves the shortcomings of the existing technology, where some silt is quite thick and it is difficult to effectively clean it by relying solely on the impeller of the sludge pump, resulting in less than ideal dredging efficiency.

[0006] This utility model provides the following technical solution:

[0007] A silt and sediment pipeline transport and dredging device, comprising:

[0008] The sludge pump body has a connecting flange fixedly installed at the other end of the sewage pipe at the outlet of the sludge pump body for connecting to the conveying pipeline. The sludge pump body is detachably equipped with a U-shaped mounting frame, and hollow seats are provided on both sides of the U-shaped mounting frame.

[0009] The mixing component, located on the hollow seat, is used to mix the sludge into a slurry so that the sludge pump body can suck it in.

[0010] An adjustment component, located between the U-shaped mounting bracket and the hollow seat, is used to adjust the inclination of the hollow seat so that the mud can flow into the bottom inlet of the mud pump body.

[0011] In one possible design, two connecting rods are welded to both sides of the mud pump body. The other ends of the two adjacent connecting rods are fixedly provided with the same mounting plate. The mounting plate is symmetrically threaded with two fixing bolts for reinforcing the U-shaped mounting bracket and the mounting plate. The ends of the fixing bolts pass through corresponding threaded holes and are threadedly connected with matching fixing nuts.

[0012] In one possible design, the stirring assembly includes a transmission rod rotatably mounted within the cavity of a hollow seat. A drive motor for driving the transmission rod to rotate is fixedly mounted on the top of the hollow seat. The top end of the transmission rod passes through the cavity opening at the top of the hollow seat and is fixedly connected to the output shaft of the drive motor. The bottom end of the transmission rod passes through the cavity opening at the bottom of the hollow seat and is fixedly mounted with a rotating seat. Multiple downwardly inclined stirring blades are fixedly connected in a rectangular array on the side wall of the rotating seat. Multiple stirring teeth for improving stirring efficiency are fixedly arranged at equal intervals at the edges of the stirring blades.

[0013] In one possible design, the adjustment assembly includes a second hinge seat and a first hinge seat fixedly disposed on the outer wall of the hollow seat. An electric push rod is hinged to the second hinge seat, and a third hinge seat is hinged to the other end of the electric push rod. The side wall of the third hinge seat is fixedly connected to the outer wall of the U-shaped mounting bracket. A support rod is hinged to the first hinge seat, and the other end of the support rod is fixedly connected to the outer wall of the U-shaped mounting bracket.

[0014] In one possible design, a waterproof box with a built-in battery is fixedly connected to the middle position of the top of the U-shaped mounting bracket, and the wires of the two electric push rods are plugged into the battery interface inside the waterproof box.

[0015] In one possible design, the top of the U-shaped mounting bracket is symmetrically fixed with two hooks for easy suspension of the moving device.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] Before use, use the mounting plates on the connecting rods welded on both sides of the sludge pump body, and use fixing bolts and matching fixing nuts to reinforce the U-shaped mounting frame to the sludge pump body. Connect the connecting flange at the other end of the sewage pipe at the outlet of the sludge pump body to the conveying pipeline. Use the hooks symmetrically set on the top of the U-shaped mounting frame and use a suspension moving device (such as a crane) to move the equipment to a suitable position in the dredging water area.

[0019] After starting the drive motor on top of the hollow base, the drive motor drives the transmission rod to rotate, and the rotating seat at the bottom of the transmission rod rotates accordingly. Multiple stirring blades arranged in a rectangular array on the side wall of the rotating seat begin to stir the sludge. The stirring teeth at the edges of the stirring blades further improve the stirring efficiency, stirring the thick sludge into slurry. According to the flow of the slurry, the extension and retraction of the electric push rod can be controlled. One end of the electric push rod is hinged to the second hinge seat on the outer wall of the hollow base, and the other end is hinged to the third hinge seat on the outer wall of the U-shaped mounting bracket. As the electric push rod extends and retracts, the hollow base rotates around the support rod hinged on the first hinge seat, thereby adjusting the inclination of the hollow base so that the slurry can be better guided into the bottom inlet of the sludge pump body. At the same time, the sludge pump body sucks the stirred slurry into the pump body through the rotation of the impeller. Under the action of centrifugal force, the slurry is discharged from the outlet of the sludge pump body and transported to the designated location through the sewage pipe and the connected conveying pipe.

[0020] This utility model has the following beneficial effects:

[0021] This invention, through the inclusion of a stirring component, can agitate thick silt into slurry, solving the problem that relying solely on the impeller of a slurry pump is insufficient for effectively cleaning thick silt. This allows the slurry pump to operate more smoothly, significantly improving dredging efficiency. The adjustment component can adjust the inclination of the hollow seat according to actual conditions, enabling the slurry to flow better into the bottom inlet of the slurry pump body, ensuring smooth slurry delivery and further enhancing the dredging effect.

[0022] In this utility model, the sludge pump body and the U-shaped mounting frame are reinforced and installed by connecting rods, mounting plates, fixing bolts and fixing nuts, which is convenient and quick. At the same time, the hooks on the top of the U-shaped mounting frame facilitate the use of a suspension moving device to move the equipment, which can be flexibly applied to different dredging scenarios.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] Example 1

[0032] Please refer to Figure 1-4 A dredging device, comprising:

[0033] The sludge pump body 1, model NSL100-35, has a sewage pipe 2 connected to its output port. A connecting flange 3 is fixedly installed at the other end of the sewage pipe 2, allowing it to connect to a conveying pipeline, thus preparing for the subsequent transport of pumped sludge to a designated location. A U-shaped mounting bracket 6 is detachably mounted on the outside of the sludge pump body 1. The U-shaped mounting bracket 6 is made of 316L stainless steel, offering strong corrosion resistance and suitability for aquatic environments. During installation, two connecting rods 4 are welded to both sides of the sludge pump body 1. The other end of each of the two adjacent connecting rods 4 is fixedly fitted with the same mounting plate 5. The U-shaped mounting bracket 6 is placed in a suitable position, aligning the mounting plate 5 with the U-shaped mounting bracket 6. Then, fixing bolts 7 are passed through the threaded holes on the mounting plate 5 and the through holes on the U-shaped mounting bracket 6, and a matching fixing nut 8 is threaded onto the end to reinforce the U-shaped mounting bracket 6 and the mounting plate 5, ensuring the U-shaped mounting bracket 6 is securely installed outside the sludge pump body 1.

[0034] The U-shaped mounting bracket 6 has hollow seats 9 on both sides, and a stirring assembly is installed on the hollow seat 9. The stirring assembly includes a transmission rod 14 rotatably installed in the cavity of the hollow seat 9. A drive motor 11 is fixedly installed on the top of the hollow seat 9 to drive the transmission rod 14 to rotate. The top end of the transmission rod 14 passes through the top of the hollow seat 9 and is fixedly connected to the output shaft of the drive motor 11 through a coupling. Its bottom end passes through the bottom of the hollow seat 9 and is fixedly installed on a rotating seat 10. Multiple downwardly inclined stirring elements are fixedly connected in a rectangular array on the side wall of the rotating seat 10. The mixing blade 12 (the mixing blade 12 is made of tungsten carbide coating + high chromium cast iron substrate, which has good wear resistance and is resistant to sludge impact) has multiple mixing teeth 13 evenly arranged on the edge of the mixing blade 12 to improve mixing efficiency. When the equipment starts working, the drive motor 11 is started, the drive motor 11 drives the transmission rod 14 to rotate, and the transmission rod 14 drives the rotating seat 10 to rotate, so that the mixing blade 12 and the mixing teeth 13 rotate accordingly, stirring the surrounding sludge, stirring the thick sludge into mud, which is convenient for the mud pump body 1 to suck up, thus improving the dredging efficiency.

[0035] An adjustment assembly is provided between the U-shaped mounting bracket 6 and the hollow seat 9 to adjust the inclination of the hollow seat 9. The adjustment assembly includes a first hinge seat 16 and a second hinge seat 18 fixedly mounted on the outer wall of the hollow seat 9. An electric push rod 17 is hinged to the second hinge seat 18, and a third hinge seat 22 is hinged to the other end of the electric push rod 17. The side wall of the third hinge seat 22 is fixedly connected to the outer wall of the U-shaped mounting bracket 6. A support rod 15 is hinged to the first hinge seat 16, and the other end of the support rod 15 is also fixedly connected to the outer wall of the U-shaped mounting bracket 6. When it is necessary to adjust the inclination of the hollow seat 9, the electric push rod 17 is activated. The extension and retraction of the electric push rod 17 will cause the hollow seat 9 to rotate around the hinge point of the first hinge seat 16 and the support rod 15, thereby realizing the adjustment of the inclination of the hollow seat 9, so that the stirred mud can be better guided into the bottom inlet of the mud pump body 1.

[0036] To provide power, a waterproof box 19 is fixedly connected to the middle of the top of the U-shaped mounting bracket 6. The waterproof box 19 is made of PPS engineering plastic with a silicone sealing ring, has a waterproof rating of IP68, and is resistant to chemical corrosion. A battery is installed inside the waterproof box 19, and the wires 20 of the two electric actuators 17 are connected to the battery interface inside the waterproof box 19 to ensure the normal operation of the electric actuators 17.

[0037] This application can be used for dredging and transporting silt in pipelines, and can also be used in other fields applicable to this application.
