Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a silt-receiving device for water conservancy projects. Background Technology

[0002] In the field of water conservancy engineering construction and river management, silt removal is a key link in ensuring water flow, flood control safety and ecological restoration. Traditional silt treatment methods mostly involve manual or mechanical excavation and direct transportation. However, silt has a high water content and complex impurities, such as stones and branches, resulting in high transportation costs and a high risk of secondary pollution. To solve this problem, the industry has gradually introduced solid-liquid separation technology, which uses screening equipment to separate solid impurities from liquids in silt to achieve volume reduction.

[0003] However, existing silt-receiving devices for water conservancy projects cannot effectively separate stones and branches from silt, and direct dumping of silt with high water content can easily cause secondary pollution; therefore, we propose a silt-receiving device for water conservancy projects.

[0017] Example 1

[0018] like Figures 1 to 5As shown, this utility model discloses a silt-receiving device for water conservancy projects. The technical solution adopted includes a box body 1, with a feeding hopper 2 at the top left end of the box body 1. A separating screen assembly 6 is provided on the inner top of the box body 1. The separating screen assembly 6 consists of a separating screen 61, a first screen hole group 62, a second screen hole group 63, a separating plate 64, and a vibrating motor 65. The left end and middle part of the separating screen 61 are respectively provided with the first screen hole group 62 and the second screen hole group 63. The lower left end of the separating screen 61 is provided with a separating plate 64. The lower surface of the separating plate 64 is symmetrically fixed with vibrating motors 65 at the front and back. The first screen hole group 62 is located directly below the feeding hopper 2, and the aperture of the first screen hole group 62 is smaller than that of the second screen hole group 63. Since the first screen hole group 62 at the left end of the separating screen 61 is located in the feeding hopper 2... Directly below, the screen 61 has a smaller aperture. Driven by the vibrating motor 65, the separating screen 61 vibrates at high frequency, filtering fine particles of silt and liquid through the screen 62 to the bottom. Larger particles, such as stones and branches, are retained on the screen surface, completing the primary solid-liquid separation. The front and rear ends of the separating screen 61 and the separating plate 64 are respectively connected to the auxiliary units 5 set on the front and rear sides of the box 1. The auxiliary unit 5 includes guide grooves 51, guide rods 52, T-shaped connecting blocks 53, and buffer springs 54. There are two sets of guide grooves 51, which are symmetrically arranged on the front and rear sides of the box 1. The guide rods 52 are vertically arranged in the center of the guide grooves 51, and T-shaped connecting blocks 53 are slidably installed on the outer side of the guide rods 52. The T-shaped connecting blocks 53 are respectively connected to the separating plate 61. The screen 61 and the separating plate 64 are fixedly connected at their front and rear ends. Buffer springs 54 are respectively installed at the upper and lower ends of the T-shaped connecting block 53. The buffer springs 54 are respectively fitted onto the outside of the guide rod 52. The upper and lower ends of the buffer springs 54 are fixedly connected to the T-shaped connecting block 53 and the guide groove 51, respectively. The guide rod 52 and the T-shaped connecting block 53 provide vertical guidance for the separating screen 61. The buffer springs 54 absorb vibration and impact, ensuring a stable and efficient screening process. A collection hopper 4 is inclinedly installed at the bottom inner side of the housing 1. The collection hopper 4 has a "V" shaped structure. The length of the separating screen 61 is greater than that of the separating plate 64. The right end of the separating plate 64 is located above the right end of the collection hopper 4. A drain hole 12 is provided at the bottom center of the right end of the collection hopper 4. The left end of the collection hopper 4 is connected to the left end of the housing 1. The bottom is connected by an L-shaped connecting pipe 9. A drive motor 10 is fixedly installed at the left end of the L-shaped connecting pipe 9. The output shaft of the drive motor 10 is fixedly connected to the left end of the conveying auger 11 located at the center of the bottom of the collecting hopper 4. A sludge receiving chamber 14 is located at the bottom right end of the inner side of the housing 1. A drain pipe 13 located at the bottom of the sludge receiving chamber 14 is connected to a drain hole 12. Because the collecting hopper 4 has a "V" shaped structure, it can guide the liquid to converge to the drain hole 12 at the center of the bottom, and then discharge it outward through the drain pipe 13. A sludge receiving cart 7 is installed inside the sludge receiving chamber 14. The sludge receiving cart 7 is located below the right end of the separating screen 61. Universal wheels 8 are fixedly installed at the four corners of the bottom of the sludge receiving cart 7. Through the design of the sludge receiving cart 7, the material discharged from the right end of the separating screen 61 can be collected.The casters 8 of the sludge-collecting vehicle 7 facilitate manual or mechanical pulling out of the vehicle for rapid transfer. It also includes a controller 3, located on the top right side of the front of the housing 1. The output of the controller 3 is electrically connected to the input of the vibration motor 65 and the drive motor 10, while the input of the controller 3 is electrically connected to the output of an external power supply.

[0019] The working principle of this utility model is as follows: In use, the sludge mixture is first fed into the feed hopper 2 at the top of the housing 1. The material initially falls onto the left end of the separating screen 61 of the separating screen assembly 6. Since the first screen hole group 62 at the left end of the separating screen 61 is located directly below the feed hopper 2, and the aperture of the first screen hole group 62 is relatively small, the separating screen 61 vibrates at high frequency under the drive of the vibrating motor 65. This filters the fine sludge and liquid particles through the first screen hole group 62 to the bottom, while larger particles, such as stones and branches, are retained on the screen surface, completing the primary solid-liquid separation. Stones that do not pass through the first screen hole group 62 move to the right with the vibration of the separating screen 61, reaching the second screen hole group 63 in the middle. The aperture of the second screen hole group 63 is larger than that of the first screen hole group 62, which facilitates the infiltration of larger particles. Stones that cannot infiltrate continue to slide to the right along the separating screen 61, eventually falling into the sludge receiving cart 7 inside the sludge receiving chamber 14. The sludge receiving cart 7 is equipped with casters 8 at the bottom, allowing for manual loading when full. Alternatively, it can be mechanically pulled out to achieve rapid transfer; at this time, the guide rod 52 of the auxiliary unit 5 and the T-shaped connecting block 53 provide vertical guidance for the separation screen 61, and the buffer spring 54 absorbs vibration impact to ensure a stable and efficient screening process; the liquid and material seep down to the separation plate 64 through the screen hole group 1 62 and the screen hole group 2 63, while the separation plate 64 has no screen hole design, and its right end extends to the upper right end of the collection hopper 4. Under the action of the vibration motor 65, the separation plate 64 accelerates the material to be discharged to the collection hopper 4. The collection hopper 4 has a "V" shaped structure, which guides the liquid to converge to the drain hole 12 at the bottom center, and then discharges it outward through the drain pipe 13, while the solid material slides down the slope to the bottom of the collection hopper 4. By starting the drive motor 10, the drive motor 10 drives the conveying auger 11 to rotate, and the conveying auger 11 conveys the solid material that has slid down to the bottom of the collection hopper 4 to the L-shaped connecting pipe 9, and finally discharges it from the other end opening of the L-shaped connecting pipe 9.
