Description

A dredging and filtration device for river water conservancy construction Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a dredging and filtration device for river water conservancy construction. Background Technology

[0002] A dredging and filtration device for river water conservancy construction is a specialized piece of equipment used in river water conservancy construction to remove silt from the riverbed and filter the silt-water mixture. It generally consists of multiple functional components, such as a filtration mechanism that can intercept impurities and particles in the silt, a dredging component that is responsible for stirring up the silt from the riverbed and transporting it to the filtration area, and some are also equipped with an automatic filter screen cleaning device to prevent impurities from clogging the filter screen, thereby achieving efficient and continuous dredging and filtration operations, ensuring smooth river flow, and improving river water quality and the ecological environment.

[0003] Existing filtration devices rely solely on scraping the surface of the filter screen with a scraper when cleaning it, which has significant limitations. Fine impurities easily embed themselves deep within the filter screen pores, making them inaccessible to the scraper. Furthermore, highly viscous impurities, such as colloids in river silt, are difficult to completely remove. This not only reduces filtration efficiency but also affects the lifespan and operational stability of the device. Summary of the Invention

[0004] The purpose of this utility model is to provide a dredging and filtration device for river water conservancy construction, which solves the technical problems mentioned in the background art by setting up a filtration mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dredging and filtration device for river water conservancy construction, including a dredging box, on which a filtration mechanism and a configuration mechanism are provided;

[0007] The filtration mechanism includes a filter screen slidably connected to a sludge removal box. A waterproof cover is fixedly connected to the top of the filter screen. A motor is fixedly connected to the inner wall of the waterproof cover. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the filter screen and is rotatably connected to it. A support rod module is fixedly fitted onto the outer wall of the rotating shaft. Two rotating rods are rotatably connected to the support rod module. The top ends of the two rotating rods extend outside the support rod module. A cleaning brush is fixedly fitted onto the outer wall of each of the two rotating rods. Both cleaning brushes are in contact with the filter screen. A small gear is fixedly fitted onto the outer wall of each of the two rotating rods. A large gear is fixedly connected to the inner wall of the filter screen.

[0008] Furthermore, both of the small gears mesh with the large gear, and a connecting pipe is fixedly connected to the outer wall of the filter screen, the connecting pipe communicating with the filter screen.

[0009] Furthermore, the configuration mechanism includes two fixing components and a crushing component. The fixing components include a locking block fixedly connected to the outer wall of the filter screen. A U-shaped block is fixedly connected to the top of the sludge removal box. A pull rod is slidably connected to the U-shaped block. A locking block is fixedly connected to the left end of the pull rod. The left end of the locking block extends into the locking block and is slidably connected to the locking block.

[0010] Furthermore, a limiting rod is slidably connected to the U-shaped block, and the left end of the limiting rod is fixedly connected to the locking block.

[0011] Furthermore, a spring is wound around the outer wall of the pull rod, one end of the spring is fixedly connected to the U-shaped block, and the other end of the spring is fixedly connected to the latch block.

[0012] Furthermore, the crushing assembly includes a second waterproof cover fixedly connected to the right side of the sludge removal box, a second motor fixedly connected to the inner wall of the second waterproof cover, and a second rotating shaft fixedly connected to the output shaft of the second motor via a coupling.

[0013] Furthermore, the second rotating shaft passes through the sludge removal box and is rotatably connected to the sludge removal box. A crushing roller is fixedly sleeved on the outer wall of the second rotating shaft, and the crushing roller is adapted to the sludge removal box.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a filtration mechanism, allows for the activation of motor one when impurities clog the filter screen during prolonged use. Motor one drives the support rod module to rotate via a rotating shaft one. Since there are two rotating rods on the support rod module, the rotation of the support rod module will synchronously drive the rotating rods and the cleaning brushes on the rotating rods to rotate. During the rotation of the rotating rods, the small gear on the rotating rods will mesh with the large gear inside the filter screen, so that the two rotating rods can drive the cleaning brushes on them to revolve around the filter screen while also rotating on their own axis, thereby improving the cleaning efficiency of the filter screen.

[0016] 2. This utility model, through the configuration mechanism, allows for the removal of the filter screen during replacement and maintenance by pulling outwards on two levers. Each lever engages with a limiting rod, causing the latches connected to it to move outwards, thus releasing the limiting action on the filter screen and allowing for its disassembly. Simultaneously, as the levers move outwards, they also work with a U-shaped block to compress the spring on its outer wall, allowing the spring to store energy for subsequent resetting.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5. This utility model is a dredging and filtration device for river water conservancy construction, including a dredging box 1, a filtration mechanism 2 and a configuration mechanism 3 on the dredging box 1.

[0028] The filtration mechanism 2 includes a filter screen 21 slidably connected to the sludge removal box 1. A waterproof cover 22 is fixedly connected to the top of the filter screen 21. A motor 23 is fixedly connected to the inner wall of the waterproof cover 22. The output shaft of the motor 23 is fixedly connected to a rotating shaft 24 via a coupling. The rotating shaft 24 passes through the filter screen 21 and is rotatably connected to the filter screen 21. A support rod module 25 is fixedly sleeved on the outer wall of the rotating shaft 24. Two rotating rods 26 are rotatably connected to the support rod module 25. The top ends of the two rotating rods 26 extend outside the support rod module 25. A cleaning brush 27 is fixedly sleeved on the outer wall of each of the two rotating rods 26. Both cleaning brushes 27 are in contact with the filter screen 21. A small gear 28 is fixedly sleeved on the outer wall of each of the two rotating rods 26. A large gear 29 is fixedly connected to the inner wall of the filter screen 21. Both small gears 28 mesh with the large gear 29. A connecting pipe 291 is fixedly connected to the outer wall of the filter screen 21. The connecting pipe 291 communicates with the filter screen 21.

[0029] By setting up the filter mechanism 2, when some impurities clog the filter screen 21 during long-term use, the motor 23 can be started. The motor 23 will drive the support rod module 25 to rotate through the rotating shaft 24. Since there are two rotating rods 26 on the support rod module 25, when the support rod module 25 rotates, it will synchronously drive the rotating rods 26 and the cleaning brushes 27 on the rotating rods 26 to rotate. During the rotation of the rotating rods 26, the small gear 28 on the rotating rods 26 will mesh with the large gear 29 in the filter screen 21. This allows the two rotating rods 26 to drive the cleaning brushes 27 to revolve around the central axis and rotate on their own axis at the same time, thereby improving the cleaning efficiency of the filter screen 21.

[0030] Configuration mechanism 3 includes two fixing components and a crushing component. The fixing components include a locking block 31 fixedly connected to the outer wall of the filter screen 21, a U-shaped block 32 fixedly connected to the top of the sludge removal box 1, a pull rod 33 slidably connected to the U-shaped block 32, a locking block 34 fixedly connected to the left end of the pull rod 33, the left end of the locking block 34 extending into the locking block 31 and slidably connected to the locking block 31, a limiting rod 35 slidably connected to the U-shaped block 32, the left end of the limiting rod 35 fixedly connected to the locking block 34, and the outer wall of the pull rod 33 is wrapped with... Spring 36, one end of spring 36 is fixedly connected to U-shaped block 32, and the other end of spring 36 is fixedly connected to latch block 34. The crushing assembly includes a waterproof cover 37 fixedly connected to the right side of the sludge removal box 1. A motor 38 is fixedly connected to the inner wall of the waterproof cover 37. The output shaft of the motor 38 is fixedly connected to a rotating shaft 39 through a coupling. The rotating shaft 39 passes through the sludge removal box 1 and is rotatably connected to the sludge removal box 1. A crushing roller 391 is fixedly sleeved on the outer wall of the rotating shaft 39. The crushing roller 391 is adapted to the sludge removal box 1.

[0031] By setting the configuration mechanism 3, when the filter screen 21 needs to be replaced or repaired, the two pull rods 33 can be pulled outward. The two pull rods 33 will cooperate with the limiting rods 35 on them respectively, so that the locking blocks 34 connected to the two pull rods 33 can move outward, thereby releasing the limiting of the locking block 31 on the filter screen 21, thus completing the disassembly of the filter screen 21. At the same time, during the outward movement of the pull rods 33, the pull rods 33 will also cooperate with the U-shaped block 32 to compress the spring 36 on its outer wall, so that the spring 36 can accumulate energy to support the subsequent reset.

[0032] One specific application of this embodiment is as follows: During sludge suction, the connecting pipe 291 on the filter screen 21 is first connected to the sludge suction pipe. Then, the sludge in the sludge cleaning box 1 is suctioned through the sludge suction pipe. Before the suction process, motor 28 can be started. Motor 28 drives the crushing roller 391 through shaft 29 to break up the sludge entering the sludge cleaning box 1, facilitating the filter screen 21 to filter and absorb the broken sludge. This reduces the risk of large impurities in the sludge clogging the filter screen 21. The broken sludge is then filtered by the filter screen 21 and sucked into it, and then transported to the next process through the sludge suction pipe. When some impurities clog the filter screen 21 during prolonged use, motor 123 can be started. Motor 123 drives the support rod module 25 to rotate through shaft 124. Since there are two rotating rods 26 on the support rod module 25... Therefore, when the support rod module 25 rotates, it will synchronously drive the rotating rod 26 and the cleaning brush 27 on the rotating rod 26 to rotate. During the rotation of the rotating rod 26, the small gear 28 on the rotating rod 26 will mesh with the large gear 29 inside the filter screen 21, so that the two rotating rods 26 can drive the cleaning brush 27 to revolve around the revolution and also rotate on their own axis, thereby improving the cleaning efficiency of the filter screen 21. If the filter screen 21 needs to be replaced or repaired, the two pull rods 33 can be pulled outward. The two pull rods 33 will cooperate with the limiting rods 35 on them respectively, so that the latch blocks 34 connected to the two pull rods 33 can move outward, thereby releasing the limiting of the latch block 31 on the filter screen 21, thereby completing the disassembly of the filter screen 21. At the same time, during the outward movement of the pull rods 33, the pull rods 33 will also cooperate with the U-shaped block 32 to compress the spring 36 on its outer wall, so that the spring 36 can accumulate energy to support the subsequent reset.
