Description

Technical Field

[0001] This utility model relates to the field of silty soil transportation technology, specifically a pipeline transportation device for silty soil. Background Technology

[0002] Silt is a type of cohesive soil with a natural water content greater than the liquid limit and a natural void ratio between 1.0 and 1.5. It is a type of weak soil and has characteristics such as high water content, high compressibility, low strength, large void ratio and poor permeability. It is mainly distributed along the southeastern coast and inland major rivers, lakes and rivers of my country. When dredging river channels, silt needs to be extracted, transported and processed, so a transport device is required. The applicant discovered a Chinese patent, "A River Silt Conveying Device for Water Conservancy Projects," publication number CN212248462U. This patent primarily utilizes the connection points of the conveying device to ensure uniform force distribution, eliminating the need for bolted edge pressing and guaranteeing a sealed connection. The modular snap-fit ​​connection allows for quick assembly and disassembly without tools, saving time and effort. It also allows for rapid assembly when replacing pipes or extending the conveying length. Furthermore, the high viscosity of the silt facilitates transport, and for longer pipelines, it allows for relay transport to ensure complete delivery. However, some shortcomings exist in practical use. When extracting and transporting silt with low water content, the high hardness leads to increased damping, and the dryness and hardening of the silt can cause blockages, resulting in poor stability and low efficiency in silt extraction and transport. Therefore, we propose a pipeline-based silt conveying device. Utility Model Content

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0016] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Please see the appendix Figure 1 -Appendix Figure 5 This utility model discloses a pipelined conveying device for silty soil, comprising an extraction pipe 1, a bend 101 fixedly installed at one end of the extraction pipe 1, a motor base 105 fixedly installed at the top of the bend 101, a drive motor 4 fixedly installed at the top of the motor base 105, a drive gear 401 fixedly installed at the output end of the drive motor 4, a drive pipe 5 extending into the extraction pipe 1 rotatably installed inside the motor base 105, a spiral auger 501 fixedly installed on the outer wall of the drive pipe 5, a gear disk 504 meshing with the drive gear 401 fixedly installed at one end of the drive pipe 5, water injection heads 502 fixedly installed at equal intervals on the outer wall of the drive pipe 5, and multiple sets of water injection pipes 3 fixedly installed on the top of the outer wall of the extraction pipe 1, with water distribution pipes 301 fixedly connected between the water injection pipes 3.

[0018] Specifically, the extraction pipe 1, serving as the main conveying channel, is preferably made of wear-resistant steel to withstand the abrasion of silty soil. A bend 101 is fixedly installed at the conveying end of the extraction pipe 1 by welding. The bending angle of the bend 101 can be designed according to the actual construction site and the direction of material feeding, for example, using an obtuse angle of 90 degrees or greater, to facilitate flexible alignment with the silt to be extracted. A motor base 105 is fixedly installed at the top of the bend 101 by welding. A drive motor 4 is bolted to the top of the motor base 105. The drive motor 4 is preferably a speed-adjustable, waterproof three-phase asynchronous motor to adjust the conveying speed according to the consistency of the silt. A drive gear 401 is fixedly mounted on the output shaft of the drive motor 4 via a key connection. Inside the motor base 105, a drive tube 5 is rotatably mounted via a bearing. One end of the drive tube 5 extends to the bend 101 and into the extraction tube 1. A gear disk 504 is fixedly mounted at the end of the drive tube 5 inside the motor base 105. The gear disk 504 meshes with the drive gear 401 on the output shaft of the drive motor 4, forming a gear transmission. When the drive motor 4 starts, the drive gear 401 drives the gear disk 504 and the drive tube 5 to rotate together. The drive tube 5 serves as the core rotating shaft, with most of its length located inside the extraction tube 1. A spiral auger 501 is continuously and axially fixedly installed on the outer wall of the section extending into the extraction pipe 1. The outer diameter of the blades of the spiral auger 501 maintains a small gap with the inner wall of the extraction pipe 1, ensuring effective pushing capability while preventing jamming. During operation, the rotation of the drive pipe 5 drives the spiral auger 501 to rotate, thereby generating a continuous axial thrust on the silty soil, realizing the pipelined transport of silt. The drive pipe 5 is a hollow tube, with an internal water conveyance channel. Multiple water injection heads 502 are fixedly installed at equal intervals on the outer wall of the drive pipe 5 corresponding to the internal section of the extraction pipe 1. These water injection heads 502 communicate with the internal cavity of the drive pipe 5, allowing water to be injected through the drive pipe. The internal water of the pump 5 is sprayed out through the water injection head 502, which can lubricate the inside of the silty soil inside the extraction pipe 1. At the top of the outer wall of the extraction pipe 1, multiple sets of water injection pipes 3 are fixedly welded at equal intervals along the axial direction. The water inlet ends of these water injection pipes 3 are interconnected through a water distribution pipe 301. The water distribution pipe 301 serves as a main water inlet manifold and can be connected to an external high-pressure water source. Thus, the water injection pipes 3 can lubricate the outside of the silty soil inside the extraction pipe 1. This design allows the lubricating water to be sprayed directly and evenly from the axis of the rotating auger 501 into the surrounding silt, achieving efficient lubrication, dilution, and disturbance, and significantly improving the conveying efficiency.

[0019] In Example 1, a one-way valve plate 503 is movably installed inside the water injection head 502, a pressing rod 303 is fixedly installed on the top of the water injection pipe 3, the bottom of the pressing rod 303 extends into the water injection pipe 3 and a drain plate 304 is fixedly installed thereon, an operating disc 305 is fixedly installed on the top of the pressing rod 303, a return spring 306 is sleeved on the outer wall of the pressing rod 303, a rotary joint 505 is fixedly installed at one end of the drive pipe 5, a connecting pipe 506 is fixedly installed at one end of the rotary joint 505, and an extraction cover 2 is fixedly installed at the other end of the extraction pipe 1 through a fixing ring 104, and a filter rod 201 is fixedly installed on the outside of the extraction cover 2. Specifically, inside each water injection head 502, a one-way valve plate 503 is movably installed via a hinge. Under normal water pressure, the one-way valve plate 503 is opened by the water flow, allowing water to spray out. When the water supply stops or the pressure inside the pipeline is too high, the valve plate automatically closes under back pressure or sludge action, effectively preventing sludge backflow from clogging the water injection channel. At the top of each water injection pipe 3, a pressing rod 303 is slidably installed in a sealed manner. The bottom of the pressing rod 303 extends into the inside of the water injection pipe 3 and a drain plate 304 is fixedly installed thereon. Its diameter is adapted to the inner diameter of the water injection pipe 3. The top of the pressing rod 303 protrudes from the water injection pipe 3 and an operating disc 305 for easy pressing is fixedly installed thereon. A reset spring 306 is sleeved on the outer wall of the pressing rod 303 between the operating disc 305 and the top of the water injection pipe 3. When the water injection pipe 3 is blocked by impurities, simply press the operating disc 305 to push the unblocking plate 304 downward and forcefully flush out the blockage. After releasing, the unblocking plate 304 resets under the action of the reset spring 306, achieving rapid unblocking. The drive pipe 5 is fixedly connected to a connecting pipe 506 through a rotary joint 505, and the connecting pipe 506 is then connected to an external water supply hose. External high-pressure water flows sequentially through connecting pipe 506 and rotary joint 505 into the interior of rotating drive pipe 5, and finally sprays out from multiple water injection heads 502 distributed along the axial direction of drive pipe 5 to lubricate and dilute the sludge. At the feed end of extraction pipe 1, extraction cover 2 is detachably fixed by a fixing ring 104. Extraction cover 2 is funnel-shaped to expand the extraction area. Multiple filter rods 201 are welded to the outside of extraction cover 2 to form a protective grid, which can effectively prevent large stones, plastic bags and other debris from being sucked into the pipe, thereby protecting the internal spiral auger 501 from damage.

[0020] In embodiment 2, a corrugated pipe 102 is fixedly installed at one end of the bend 101, a flange 103 is fixedly installed at one end of the corrugated pipe 102, a gear cover 402 is fixedly installed on one side of the drive motor 4, the gear cover 402 is sleeved on the outside of the drive gear 401 and the gear disk 504, and a quick connector 302 is fixedly installed at one end of the water distribution pipe 301. Specifically, a section of corrugated pipe 102 is fixedly installed at the feed end of the bend 101. The corrugated pipe 102 has good flexibility, and a flange 103 is fixedly installed at the other end. The flange 103 can be connected to the external conveying pipeline. The design of the corrugated pipe 102 allows the operator to flexibly adjust the orientation and position of the connection within a certain range, greatly improving the equipment's adaptability to complex terrain. On one side of the drive motor 4, a gear cover 402 is fixedly installed with bolts. The gear cover 402 completely covers the drive gear 401 and gear disk 504. This design can effectively prevent dust and mud from entering the gear transmission pair, extending the service life of the gears, and also eliminating the safety hazard of operators possibly coming into contact with the moving gears. At the water inlet end of the water distribution pipe 301, a quick connector 302 is fixedly installed, making the connection and disconnection of the external water supply pipe very convenient, saving installation and disassembly time, and improving work efficiency.

[0021] Working principle: One end of the extraction pipe 1 is inserted into the silty soil. The drive motor 4 drives the drive pipe 5 and the auger 501 to rotate, which can extract the silty soil. It is connected to the external conveying pipeline through the bend pipe 101 to transport the extracted silty soil. The water injection head 502 and the water injection pipe 3 can inject water during the extraction and transportation of silty soil. Water injection can lubricate and dilute the silt. The combination of mechanical pushing and water-powered lubrication ensures that the silty soil is stably and smoothly transported to the designated location in the pipeline. The one-way valve plate 503 can prevent the water injection head 502 from clogging, preventing the silty soil from entering the drive pipe 5 through the water injection head 502. The pressing rod 303 and the unblocking plate 304 can unblock the water injection pipe 3 when it is blocked, ensuring the stability of the device when lubricating the silty soil with water.
