Description

Technical Field

[0001] This utility model belongs to the field of sand-water separation technology, and in particular relates to a spiral sand-water separator. Background Technology

[0002] Sand-water separators are auxiliary equipment in sand removal systems for sedimentation tanks. They are devices used to separate sand particles and water, and are widely used in industries such as construction, mining, and environmental protection. They are particularly useful in sand washing, mud treatment, and water treatment processes. Their working principle is usually based on the sedimentation differences of substances with different densities and particle sizes in flow, separating sand particles and water through centrifugal force or gravity.

[0003] Chinese patent application number CN202121473675.X and publication number CN215691864U discloses a spiral sand-water separator, comprising: a water tank, a U-shaped conveying trough, a shaftless spiral blade, and a drive device; the U-shaped conveying trough is inclined with the left side lower than the right side; the shaftless spiral blade is disposed within the U-shaped conveying trough, with its lower section located within the water tank and its upper end connected to the drive device; a concentric column is disposed on the inner side of the shaftless spiral blade, and the diameter of the inner cylinder of the shaftless spiral blade is larger than the diameter of the concentric column. This spiral sand-water separator, by setting a concentric column with a diameter smaller than the inner cylinder of the shaftless spiral blade, forms a relatively narrow channel between the inner wall of the shaftless spiral blade and the outer cylindrical wall of the concentric column, which reduces the risk of clogging and effectively prevents sand and gravel from falling back, thus helping to improve the processing efficiency of the sand-water separator.

[0004] In summary, most existing sand-water separators have few separation structures and poor separation effect, making them unable to efficiently separate sand and water. In response, this application proposes a spiral sand-water separator. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 scope of protection of the present utility model.

[0020] Example

[0021] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a spiral sand-water separator, including a tank 1, with a partition 2 inside the tank 1. Specifically, the partition 2 is fixedly connected to the inner wall of the tank 1, and the partition 2 divides the inside of the tank 1 into a separation zone and a clear water zone. A feed pipe 3 is provided above the separation zone, and a discharge pipe 6 is provided at the bottom of the separation zone. A spiral pump assembly is provided at the bottom of the tank 1 below the clear water zone.

[0022] A plurality of inclined tubes 7 are inserted through the partition plate 2. Specifically, the inclined tubes 7 are fixedly connected to the partition plate 2. The inclined tubes 7 are inclined downward along the separation zone. A fixing plate 4 is provided on one side of the partition plate 2 in the separation zone. Specifically, the fixing plate 4 is fixedly connected to the partition plate 2. The fixing plate 4 is located above the inclined tubes 7. A filter screen 5 is provided between the bottom surface of the fixing plate 4 and the side wall of the partition plate 2 below the inclined tubes 7. Specifically, the filter screen 5 is fixedly connected to both the fixing plate 4 and the partition plate 2. The filter screen 5 cooperates with the inner wall of the separation zone to form a partition zone.

[0023] In this embodiment, the sand-water mixture is poured into the separation zone through the feed pipe 3. Under the action of gravity and the isolation of the filter screen 5, the sand and gravel sink to the bottom of the separation zone. The water passes through the filter screen 5 and enters the inclined pipe 7. The inclined pipe 7 is set at an inclination to reduce the sand and gravel throughput. The separated water enters the clear water zone and is discharged through the spiral pump assembly.

[0024] Furthermore, the interior of the inclined tube 7 is provided with several inverted conical plates 17 at intervals, and the top surface of the inverted conical plates 17 is provided with through holes 18.

[0025] In this embodiment, the inverted conical plate 17 and the through hole 18 cooperate to further block the passage of sand and gravel. First, the size of the through hole 18 can block the passage of large-diameter sand and gravel. Second, the inverted conical plate 17 will cause the sand and gravel that pass through to slide down in the opposite direction under the action of gravity.

[0026] Furthermore, the spiral pump assembly includes a pipe body 8, which is connected to the side wall of the tank 1 in the clear water zone. Specifically, the pipe body 8 is fixedly connected to the tank 1, and an inlet 9 is provided between the pipe body 8 and the tank 1. A rotating shaft 10 is provided inside the pipe body 8. Specifically, the rotating shaft 10 is rotatably connected to the pipe body 8. A spiral blade 11 adapted to the inner wall of the pipe body 8 is provided on the side wall of the rotating shaft 10. Specifically, the spiral blade 11 is welded to the rotating shaft 10. An outlet 12 is provided on the bottom surface of the pipe body 8. One end of the rotating shaft 10 passes through the end of the pipe body 8 and is connected to a drive assembly.

[0027] The drive assembly includes a housing 13, which is connected to the end of a tube 8. Specifically, the housing 13 is fixedly connected to the tube 8. The end of a rotating shaft 10 extends into the interior of the housing 13 and is connected to a first gear 14. Specifically, the rotating shaft 10 is rotatably connected to the housing 13 and is fixedly connected to the first gear 14. A motor 15 is provided outside the housing 13. Specifically, the motor 15 is fixedly connected to the housing 13. The output shaft of the motor 15 passes through the housing 13 and is connected to a second gear 16. Specifically, the output shaft of the motor 15 is rotatably connected to the housing 13 and is fixedly connected to the second gear 16. The first gear 14 and the second gear 16 mesh with each other.

[0028] In this embodiment, the motor 15 rotates, driving the second gear 16 to rotate and pushing the first gear 14 to rotate, which in turn drives the rotating shaft 10 to rotate. The spiral blade 11 rotates with the rotating shaft 10, bringing water into the pipe body 8 through the inlet 9 and discharging it through the outlet 12.

[0029] Furthermore, the top surface of the fixing plate 4 is inclined.

[0030] In this embodiment, the top surface of the fixing plate 4 is inclined to facilitate the sand and gravel to slide to the bottom of the separation zone.

[0031] Furthermore, the filter screen 5 is spaced out with several layers to form a multi-layer filtration system, thereby improving the separation effect.
