Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation technology, specifically a soil and water conservation sedimentation device. Background Technology

[0002] In practical engineering, sedimentation for soil and water conservation has been widely applied in various water conservancy projects, municipal engineering projects, and ecological restoration projects. For example, in river management, the installation of sedimentation ponds and other facilities has effectively reduced the siltation of downstream river channels.

[0003] Soil and water conservation sedimentation devices typically include key components such as the sedimentation tank body, filter baskets, and floats. The sedimentation tank body is used to contain and settle sediment in the water flow; the filter baskets are used to further filter out suspended solids in the water; and the floats may be used to regulate the water flow velocity or as a supporting structure.

[0004] Existing sedimentation devices lack an effective water flow disturbance mechanism, making it difficult for sediment particles to be fully suspended and separated from the water flow. This results in low sediment separation efficiency and a large amount of sediment flowing out with the water flow, affecting the water purification effect. Therefore, a sedimentation device for soil and water conservation is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, existing sedimentation devices lack an effective water flow disturbance mechanism, which makes it difficult for sediment particles to be fully suspended and separated from the water flow. This results in low sediment separation efficiency and a large amount of sediment flowing out with the water flow, affecting the water purification effect. This utility model proposes a sedimentation device for soil and water conservation.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A sedimentation device for soil and water conservation, comprising a sedimentation tank; an inlet and an outlet are respectively provided at both ends of the sedimentation tank; an inlet pipe is fixedly installed on the outside of the inlet, and an outlet pipe is fixedly connected to the outside of the outlet; a rotating shaft is provided at one end of the inlet pipe; both ends of the rotating shaft are rotatably mounted in the sedimentation tank via bearings; multiple rotating blades are arrayed and fixedly installed on the outer circumference of the rotating shaft; one end of the rotating shaft penetrates the sedimentation tank and is fixedly installed with a control wheel; a control box is fixedly installed on the outside of the sedimentation tank directly above the control wheel; a pressure plate is slidably installed in the upper part of the control box; sliding holes are provided on both sides of the bottom of the pressure plate; sliding rods are slidably installed in the sliding holes; a control block is fixedly installed at the lower end of the sliding rod; springs are provided between the bottom of the pressure plate and the upper ends of the control block, fitted onto the sliding rod; the lower end of the control block penetrates the bottom of the control box, and... The bottom curved surface fits into the upper curved surface of the control wheel. Two rotating rollers are arranged parallel to each other at the bottom of one end and the upper part of the other end of the sedimentation tank. The rotating rollers rotate in coordination with a conveyor belt. Multiple permeable holes are arrayed on the surface of the conveyor belt. A V-shaped plate is fixedly installed in the sedimentation tank between the bottom of the rotating roller and the upper part of the outlet pipe. One side of the V-shaped plate is fixedly connected to the inner wall of the sedimentation tank, and the other side is tangent to the inclined surface of the bottom of the conveyor belt. A motor is fixedly installed on one side of the outlet end of the sedimentation tank. The rotating shaft of the motor is fixedly connected to one end of the rotating roller. A discharge port is opened on one side of the outlet end of the sedimentation tank, and a guide plate is fixedly installed on the discharge port. At the same time, the continuous conveying of the conveyor belt and the design of the permeable holes realize the uniform sedimentation and efficient cleaning of silt. In addition, the design of the adjustment mechanism allows the device to be flexibly adjusted according to different water flow conditions and silt content, further improving the sedimentation efficiency and the quality of the effluent.

[0007] Preferably, a cylinder is fixedly installed on the top of the control box, and the piston rod of the cylinder is fixedly connected to the center of the upper part of the pressure plate. By controlling the extension and retraction of the cylinder, the position of the pressure plate can be quickly and stably adjusted, thereby flexibly controlling the pressure of the control block on the control wheel, and achieving the purpose of adjusting the rotation speed of the shaft and the disturbance intensity of the rotating blade.

[0008] Preferably, guide plates are fixedly installed on the inner walls of both sides of the sedimentation tank. The guide plates are Z-shaped and have Z-shaped holes. The guide plates are respectively sleeved on both sides of the conveyor belt. By setting the guide plates, the Z-shaped design of the guide plates not only enhances the scouring effect of the water flow on the sediment particles, but also promotes the deposition of sediment particles in the direction of the conveyor belt, further improving the sediment deposition efficiency and separation effect.

[0009] Preferably, a roller brush is provided between the two rotating rollers at the outlet end of the sedimentation tank. Both ends of the roller brush are rotatably installed in the sedimentation tank through bearings. By setting the roller brush, its rotational action effectively cleans the mud and sand residue on the surface of the conveyor belt. The introduction of the roller brush significantly improves the cleaning efficiency and separation effect of the device, and provides more convenient conditions for subsequent mud and sand treatment.

[0010] Preferably, an auger is provided between the V-shaped plate and the conveyor belt. One end of the auger is rotatably installed in the sedimentation tank, and the other end is rotatably installed in the discharge port. By setting up the auger, the rotation of the auger realizes the centralized and efficient transportation of mud and sand. The spiral structure of the auger not only enhances the transportation capacity of mud and sand, but also ensures the uniform distribution of mud and sand during the transportation process, avoiding local accumulation.

[0011] Preferably, the rotating roller, the roller brush, and the auger all pass through the sedimentation tank at the same end and are fixedly installed with rotating wheels. The rotating wheels rotate in coordination with each other through belts. Through the transmission between the belts, synchronous operation and efficient coordination between the components are achieved, which not only simplifies the structure of the device, but also improves the transmission efficiency and stability between the components.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, when using a sedimentation device to separate sediment in water, involves water containing sediment entering the sedimentation tank through an inlet pipe. The water flow drives a rotating blade, activating a cylinder. The piston rod of the cylinder pushes a pressure plate downwards. The pressure plate compresses a spring via a slide rod, causing a control block to move downwards. Adjusting the friction between the control block and the control wheel controls the rotation speed of the rotating blade, thus disturbing the water flow. Sediment particles gradually settle on a conveyor belt, which is continuously rotated by a rotating roller. The permeable holes on the conveyor belt allow water to flow smoothly, while sediment particles are blocked. As the conveyor belt moves, the sediment particles are transported to the outlet of the sedimentation tank and then subjected to... Under the influence of gravity, the sediment falls into the V-shaped plate. The spiral structure of the auger concentrates and transports the sediment particles to the outlet, and the guide plate leads them out of the device. This structural design enhances the water flow disturbance and achieves efficient sediment separation. It solves the problem that existing sedimentation devices lack an effective water flow disturbance mechanism, which makes it difficult for sediment particles to be fully suspended and separated from the water flow. This results in low sediment separation efficiency, a large amount of sediment flowing out with the water flow, and affects the water purification effect. The sediment separation efficiency is improved, ensuring a significant improvement in the quality of the effluent. At the same time, it effectively reduces the risk of outlet blockage caused by sediment accumulation, extends the service life of the device, and reduces subsequent maintenance and cleaning costs.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a soil and water conservation sedimentation device includes a sedimentation tank 1. The sedimentation tank 1 has an inlet and an outlet at both ends. An inlet pipe 2 is fixedly installed on the outside of the inlet, and an outlet pipe 3 is fixedly connected to the outside of the outlet. A rotating shaft 4 is installed at one end of the inlet pipe 2. Both ends of the rotating shaft 4 are rotatably mounted inside the sedimentation tank 1 via bearings. Multiple rotating blades 5 are fixedly arranged in an array on the outer circumference of the rotating shaft 4. One end of the rotating shaft 4 penetrates the sedimentation tank 1 and is fixedly mounted with a control wheel 6. A control box 17 is fixedly installed on the outside of the sedimentation tank 1 directly above the control wheel 6. A pressure plate 20 is slidably installed inside the upper end of the control box 17. Sliding holes are opened on both sides of the bottom of the pressure plate 20, and sliding rods 19 are slidably installed inside the sliding holes. A control block 18 is fixedly installed at the lower end of the sliding rod 19. The bottom of the pressure plate 20 and the upper part of the control block 18 are connected. Springs 21 are installed on slide rods 19 at both ends. The lower end of control block 18 penetrates the bottom of control box 17, and the bottom curved surface fits the upper curved surface of control wheel 6. Two rotating rollers 7 are arranged parallel to each other at the bottom of one end and the upper part of the other end of sedimentation tank 1. The rotating rollers 7 rotate in cooperation with conveyor belt 8. Multiple water-permeable holes are arrayed on the surface of conveyor belt 8. A V-shaped plate 12 is fixedly installed in sedimentation tank 1 between the bottom of rotating roller 7 and the upper part of water outlet pipe 3. One side of the V-shaped plate 12 is fixedly connected to the inner wall of sedimentation tank 1, and the other side is tangent to the inclined surface of bottom of conveyor belt 8. A motor 9 is fixedly installed on the water outlet side of sedimentation tank 1. The rotating shaft of motor 9 is fixedly connected to one end of rotating roller 7. A discharge port is opened on the water outlet side of sedimentation tank 1, and a guide plate 16 is fixedly installed on the discharge port.During operation, when using the sedimentation device to separate sediment from the water body, the water containing sediment flows into the sedimentation tank 1 through the inlet pipe 2, driving the rotating blade 5 to rotate. At this time, the cylinder 22 is activated, and its piston rod pushes the pressure plate 20 downward. The pressure plate 20 compresses the spring 21 through the slide rod 19, and drives the control block 18 to move downward, thereby adjusting the friction between the control block 18 and the control wheel 6. This friction control mechanism can flexibly adjust the speed of the rotating blade 5, thereby achieving precise control of water flow disturbance. At the same time, the motor 9 is activated, and its rotating shaft drives the rotating roller 7 to start rotating. Through the belt 15, it drives the rotating wheel 14 of the roller brush 11 and the auger 13 to rotate, thereby driving the rotating roller 7 and the roller brush 11 to rotate. The brush 11 and the auger 13 rotate synchronously, simultaneously driving the conveyor belt 8 to rotate. The rotating blades 5 disturb the water flow, and the silt particles gradually settle on the conveyor belt 8. The conveyor belt 8 is driven by the rotating roller 7 to rotate continuously. The permeable holes on its surface allow water to flow smoothly, while the silt particles are blocked on the conveyor belt 8. As the conveyor belt 8 moves, the silt particles are transported to the outlet of the sedimentation tank 1. At the same time, the rotating brush 11 cleans the permeable holes on the conveyor belt 8. The silt particles fall into the V-shaped plate 12 under the action of gravity. The auger 13 rotates, transporting the silt particles along the spiral path to the discharge port, and then discharges them from the sedimentation tank 1 through the guide plate 16. The clean water, after removing the silt, is discharged from the sedimentation tank 1 through the outlet pipe 3.

[0023] A cylinder 22 is fixedly installed on the top of the control box 17. The piston rod of the cylinder 22 is fixedly connected to the upper center of the pressure plate 20. When the sedimentation device is used to separate sediment in the water, when the sedimentation device starts to work, the water containing sediment enters the sedimentation tank 1 through the inlet pipe 2, which pushes the rotating blade 5 to rotate. At this time, the cylinder 22 is activated, and its piston rod pushes the pressure plate 20 downward. The pressure plate 20 compresses the spring 21 through the slide rod 19 and drives the control block 18 to move downward, thereby adjusting the friction between the control block 18 and the control wheel 6. This friction control mechanism can flexibly adjust the speed of the rotating blade 5, thereby achieving precise control of water flow disturbance.

[0024] Guide plates 10 are fixedly installed on the inner walls of both sides of the sedimentation tank 1. The guide plates 10 are Z-shaped and have Z-shaped holes. The guide plates 10 are respectively sleeved on both sides of the conveyor belt 8. During operation, when the sedimentation device is used to separate the sediment in the water, the guide plates 10 control the conveyor belt 8 to rotate within the Z-shaped holes. They not only provide a stable running track for the conveyor belt 8 through the Z-shaped holes, ensuring the smoothness and accuracy of the conveyor belt 8 during rotation, but also effectively guide and constrain the sediment particles on the conveyor belt 8 through the special design of the Z-shaped holes.

[0025] A roller brush 11 is provided between the two rotating rollers 7 at the outlet end of the sedimentation tank 1. Both ends of the roller brush 11 are rotatably installed in the sedimentation tank 1 through bearings. During operation, when the sedimentation device is used to separate the mud and sand in the water, as the conveyor belt 8 rotates continuously, the bristles of the roller brush 11 come into contact with the surface of the conveyor belt 8, brushing off the mud and sand particles attached to the conveyor belt 8.

[0026] An auger 13 is installed between the V-shaped plate 12 and the conveyor belt 8. One end of the auger 13 is rotatably installed in the sedimentation tank 1, and the other end is rotatably installed in the discharge port. During operation, when the sedimentation device is used to separate sediment in the water, when the sediment particles are transported to the outlet of the sedimentation tank 1 and fall to the V-shaped plate 12 under the action of gravity, the auger 13 starts to rotate, transporting the sediment particles along the spiral path to the discharge port, and then discharged from the sedimentation tank 1 by the guide plate 16. Through the conveying action of the auger 13, the efficient collection and discharge of sediment particles is achieved, which facilitates subsequent sediment treatment and utilization.

[0027] The rotating roller 7, the roller brush 11, and the auger 13 all pass through the sedimentation tank 1 at the same end and are fixedly installed with rotating wheels 14. The rotating wheels 14 rotate in coordination with each other through belts 15. During operation, when the sedimentation device is used to separate sediment in the water, when the motor 9 is started, the rotating roller 7 begins to rotate. Through the belt 15, it drives the rotating wheels 14 of the roller brush 11 and the auger 13 to rotate, thereby driving the rotating roller 7, the roller brush 11, and the auger 13 to rotate synchronously.

[0028] Working principle: When using a sedimentation device to separate sediment from water, the water containing sediment enters the sedimentation tank 1 through the inlet pipe 2, driving the rotating blade 5 to rotate. At this time, the cylinder 22 is activated, and its piston rod pushes the pressure plate 20 downward. The pressure plate 20 compresses the spring 21 through the slide rod 19, and drives the control block 18 to move downward, thereby adjusting the friction between the control block 18 and the control wheel 6. This friction control mechanism can flexibly adjust the speed of the rotating blade 5, thereby achieving precise control of water flow disturbance. At the same time, the motor 9 is activated, and its rotating shaft drives the rotating roller 7 to start rotating. Through the belt 15, the rotating rollers 11 and the rotating wheel 14 of the auger 13 are driven to rotate, thereby driving the rotating roller 7 to rotate. The roller brush 11 and the auger 13 rotate synchronously, driving the conveyor belt 8 to rotate. The rotating blades 5 disturb the water flow, and the mud and sand particles gradually settle on the conveyor belt 8. The conveyor belt 8 is driven by the rotating roller 7 to rotate continuously. The permeable holes on its surface allow the water to flow smoothly, while the mud and sand particles are blocked on the conveyor belt 8. As the conveyor belt 8 moves, the mud and sand particles are transported to the outlet of the sedimentation tank 1. At the same time, the rotating roller brush 11 cleans the permeable holes on the conveyor belt 8. The mud and sand particles fall into the V-shaped plate 12 under the action of gravity. The auger 13 rotates and transports the mud and sand particles along the spiral path to the discharge port. Then, the particles are discharged from the sedimentation tank 1 by the guide plate 16. The clean water with the mud and sand removed is discharged from the sedimentation tank 1 through the water outlet pipe 3.
