Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand-water filtration and separation technology, and in particular to a sand-water separation device for river dredging sand. Background Technology
[0002] River dredging sand is a mixture of sand, gravel, and mud generated during water-related engineering construction or maintenance dredging operations in water management areas such as rivers, lakes, reservoirs, and artificial waterways. After treatment, it can be widely used in construction, road building, and other fields, achieving resource recycling. In the recycling of river dredging sand, sand-water separators are often used to filter and separate the sand, gravel, and mud mixture, discharging the water and collecting the dry materials such as sand, gravel, and silt.
[0003] Traditional sand-water separators directly discharge water containing mud and sand into the separator for separation. The sand and gravel of different sizes are filtered and separated together with the mud-water mixture, resulting in low efficiency. Furthermore, since the mud-water mixture contains a lot of mud, the small-sized mud particles can easily clog the separator's filter components, further reducing the sand-water separation efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a sand-water separation device for river dredging that can perform multiple separations and avoid clogging.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sand-water separation device for river dredging sand includes:
[0007] Base plate;
[0008] A rotating cylinder, which is rotatably connected to the base plate;
[0009] The filter cartridge is located in the middle of the rotating cylinder;
[0010] The guide plate is set on the bottom plate and extends through the filter cylinder. The guide plate is used to transport the sand-water mixture.
[0011] The filter plate, located in the middle of the guide plate, is used to filter the sand-water mixture, allowing the muddy water to pass through the filter plate and fall into the filter cylinder.
[0012] The drive mechanism is used to drive the rotating cylinder to rotate, thereby driving the filter cylinder to rotate.
[0013] The scraper is located inside the filter cartridge and directly above the guide plate;
[0014] And a rotating mechanism for rotating the scraper so that the side of the scraper contacts the inner wall of the filter cartridge.
[0015] Furthermore, the guide plate is inclined and has side plates on both sides, which are vertical.
[0016] Furthermore, a first fixed cylinder and a second fixed cylinder are fixedly connected to the base plate, and a rotating cylinder is rotatably connected to the outside of the first fixed cylinder and the second fixed cylinder.
[0017] Furthermore, multiple rollers are spaced apart along the circumference of the first and second fixed cylinders, and a track is provided on the inner wall of the rotating cylinder. The track is circular, and the rollers are located inside the track.
[0018] Furthermore, the center lines of the first fixed cylinder and the second fixed cylinder coincide, and the two ends of the guide plate are respectively fixedly connected to the inside of the first fixed cylinder and the second fixed cylinder.
[0019] Furthermore, the filter cartridge has bends at both ends, the bends are annular, and the bends are connected to the rotating cylinder.
[0020] Furthermore, a guide cylinder is fixedly connected to one end of the first fixed cylinder. The guide cylinder is conical, with one end located inside the filter cylinder and the filter plate located inside the guide cylinder.
[0021] Furthermore, the drive mechanism includes a drive motor and a gear ring. The drive motor is fixedly connected to the base plate, and a drive gear is fixedly connected to the output shaft of the drive motor. The gear ring is fixedly connected to the outside of the rotating cylinder, and the gear ring meshes with the drive gear.
[0022] Furthermore, each of the first and second fixed cylinders has a mounting plate at one end close to the other. A rotating mechanism is located between the two mounting plates. The rotating mechanism includes a rotating shaft and a servo motor. The rotating shaft is rotatably connected between the two mounting plates. A scraper is located outside the rotating shaft. The output shaft of the servo motor is connected to one end of the rotating shaft.
[0023] Furthermore, it also includes a water collection cylinder, which is set on the base plate and located outside the filter cylinder, with a drain pipe at the bottom of the water collection cylinder.
[0024] The beneficial effects of this utility model are as follows:
[0025] In this invention, the sand-water separation device for river dredging sand first separates the sand and water mixture through a filter plate. Larger sand particles and stones are intercepted and discharged from the other end of the guide plate. Smaller particles, such as mud and water, pass through the filter plate into the filter cylinder. The rotation of the filter cylinder generates centrifugal force, which throws out the water from the mixture. After the water is thrown out, a scraper rotates, its top contacting the inner wall of the filter cylinder, thus scraping off the mud adhering to the inner wall and preventing clogging. The scraped mud falls onto an inclined guide plate and is discharged. This process achieves multiple separations of large-diameter sand and gravel, small-diameter mud, and water from the sand and water. Attached Figure Description

[0034] Reference Figure 1-3A sand-water separation device for river dredging sand is used to separate sand and water in river dredging sand. It is designed to perform multiple separations of dredging sand with different particle sizes and to avoid equipment blockage.
[0035] The sand-water separation equipment for river dredging includes a bottom plate 1, a rotating cylinder 6, a filter cylinder 9, a guide plate 4, a filter plate 401, a drive mechanism, a scraper 10, and a rotating mechanism.
[0036] A first fixed cylinder 5 and a second fixed cylinder 8 are fixedly connected to the base plate 1. The center lines of the first fixed cylinder 5 and the second fixed cylinder 8 coincide. Multiple rollers 13 are spaced apart along the circumference of the first fixed cylinder 5 and the second fixed cylinder 8. The inner wall of the rotating cylinder 6 is provided with a track 12, which is circular, and the rollers 13 are located inside the track 12. The stability of the rotating cylinder 6 is ensured by the rotation of the rollers 13 inside the track 12, thus ensuring the stability of the rotating cylinder 6 outside the first fixed cylinder 5 and the second fixed cylinder 8.
[0037] The filter cylinder 9 is located in the middle of the rotating cylinder 6. Both ends of the filter cylinder 9 are provided with bends, which are annular and connected to the rotating cylinder 6. When the rotating cylinder 6 rotates, it can drive the filter cylinder 9 to rotate, thereby generating centrifugal force to dehydrate and separate the mud-water mixture inside. Furthermore, the bends at both ends of the filter cylinder 9 can limit the mud-water mixture and prevent it from overflowing.
[0038] The two ends of the guide plate 4 are fixedly connected to the inside of the first fixed cylinder 5 and the second fixed cylinder 8, respectively, and the guide plate 4 is inclined. The inclined guide plate 4 facilitates the automatic transport of the sand-water mixture along the inclined guide plate 4.
[0039] In some embodiments, the guide plate 4 is provided with side plates on both sides, and the side plates are vertical. The side plates can limit the sand-water mixture, facilitating the automatic transport of the sand-water mixture along the inclined guide plate 4.
[0040] Filter plate 401 is located in the middle of guide plate 4 and extends through filter cylinder 9. Filter plate 401 is used to filter sand-water mixture, allowing muddy water to pass through filter plate 401 and fall into filter cylinder 9. Larger sand and gravel particles are intercepted, continue to be transported through inclined guide plate 4, and are discharged through the other end of guide plate 4.
[0041] In some embodiments, a guide cylinder 501 is fixedly connected to one end of the first fixed cylinder 5. The guide cylinder 501 is conical, and one end of the guide cylinder 501 is located inside the filter cylinder 9. The filter plate 401 is located inside the guide cylinder 501. The mud and water passing through the filter plate 401 will fall onto the inclined inner wall of the guide cylinder 501, thereby facilitating the mud and water to fall into the filter cylinder 9 for mud-water separation.
[0042] The first fixed cylinder 5 and the second fixed cylinder 8 each have a mounting plate at one end close to each other. A rotating mechanism is located between the two mounting plates. The rotating mechanism includes a rotating shaft and a servo motor 11. The rotating shaft is rotatably connected between the two mounting plates. The scraper 10 is located outside the rotating shaft. The output shaft of the servo motor 11 is connected to one end of the rotating shaft. The servo motor 11 drives the rotating shaft to rotate, thereby driving the scraper 10 to rotate upward, so that the side of the scraper 10 contacts the inner wall of the filter cylinder 9. At this time, the filter cylinder 9 continues to rotate, which can scrape off the soil attached to the inner wall of the filter cylinder 9. Since the scraper 10 is located directly above the guide plate 4, the scraped soil will fall directly onto the inclined guide plate 4 and be discharged through one end of the guide plate 4.
[0043] The drive mechanism includes a drive motor 2 and a gear ring 3. The drive motor 2 is fixedly connected to the base plate 1, and a drive gear is fixedly connected to the output shaft of the drive motor 2. The gear ring 3 is fixedly connected to the outside of the rotating cylinder 6, and the gear ring 3 meshes with the drive gear. Through the gear ring 3 and the drive gear, the drive motor 2 can drive the rotating cylinder 6 to rotate, thereby driving the filter cylinder 9 to rotate, generating centrifugal force to separate the mud-water mixture.
[0044] In some embodiments, to facilitate the collection of separated water, the sand-water separation device for river dredging sand further includes a water collection cylinder 7 disposed on the base plate 1. The water collection cylinder 7 is located outside the filter cylinder 9, and annular components are provided at both ends of the water collection cylinder 7. A sealing ring is provided on the inner side of the annular component, and the sealing ring contacts the outer wall of the rotating cylinder 6, thereby facilitating the collection of water thrown out when the filter cylinder 9 rotates. A drain pipe 701 is provided at the bottom of the water collection cylinder 7, through which water is easily discharged and collected.
[0045] The working principle of the sand-water separation equipment used for river dredging sand is as follows: a sand-water mixture is added to one end of the guide plate 4 at a high position. The sand-water mixture flows along the inclined guide plate 4 and enters the rotating cylinder 6.
[0046] When the sand-water mixture passes through the filter plate 401, larger sand particles and stones are intercepted by the filter plate 401, continue to move along the guide plate 4, and are discharged from the other end of the guide plate 4. The mud-water mixture passes through the filter plate 401 and falls onto the inner wall of the guide cylinder 501, and enters the interior of the filter cylinder 9 for initial separation.
[0047] Then, the drive motor 2 drives the rotating drum 6 to rotate, which in turn drives the filter cylinder 9 to rotate. The centrifugal force generated by the rotation of the filter cylinder 9 throws out the water in the mud-water mixture. The separated water is collected by the water collection cylinder 7, while the mud that has lost water is trapped inside the filter cylinder 9, thus performing secondary separation of mud and water.
[0048] After the water in the mud-water mixture is shaken out, the servo motor 11 rotates the scraper 10, causing the top of the scraper 10 to contact the inner wall of the filter cylinder 9. The filter cylinder 9 continues to rotate, scraping off the mud adhering to its inner wall. Since the scraper 10 is directly above the guide plate 4, the scraped mud falls directly onto the inclined guide plate 4 and is discharged through one end of the guide plate 4. This completes the multiple separation of large-diameter sand, small-diameter mud, and water in the mud-water mixture.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
