Description

Technical Field

[0001] This utility model relates to the field of tap water treatment technology, and in particular to a water distribution device for tap water side-flow sedimentation. Background Technology

[0002] In the water purification process of waterworks, sedimentation can remove 80% to 90% of suspended solids, playing a crucial role in the entire process. Conventional sedimentation tanks use inclined plate sedimentation devices. After installing inclined plates in the sedimentation tank, three types are classified according to the different directions of water flow and sedimentation: co-current flow, counter-current flow, and lateral flow.

[0003] Patent publication number CN213803292U discloses a lateral flow sedimentation tank with high-resistance water distribution, including a sedimentation tank body and a sludge discharge assembly. A pair of vertically installed water distribution plates are located on both sides of the sedimentation tank body. Each water distribution plate has evenly arranged through holes, and a hollow tube is inserted into each through hole. Between the pair of water distribution plates, several inclined plates are evenly arranged on the top wall of the sedimentation tank body. A sludge hopper is connected through the bottom surface of the sedimentation tank body, and a sludge discharge assembly is installed in the sludge hopper. This design solves the problems of uneven water distribution and inconvenient sludge discharge in sedimentation tanks. Furthermore, the overall design is reasonable, facilitating uniform water distribution across the entire cross-section and improving the efficiency of sludge discharge operations.

[0004] However, some fine impurities still remain in the water after sedimentation. The inlet end of the baffle plate on the side of the drain pipe lacks a filter element, so it cannot filter out the fine impurities remaining in the water. As a result, the fine impurities in the water after sedimentation will be discharged through the hollow pipe on the water distribution plate on the side of the drain pipe, making the filtration and purification of impurities in the water incomplete.

The multiple inclined plates 15 are fixedly connected to the top wall of the sedimentation tank 1, and a filter plate 18 is fixedly connected inside the sedimentation tank 1. The filter plate 18 is located on one side of the drain pipe 4. The top wall of the sedimentation tank 1 is provided with a groove 20, and a brush block 21 is connected to the groove 20 in a lifting manner. Two cylinders 6 are symmetrically fixed on the top surface of the sedimentation tank 1. The ends of the piston rods of the two cylinders 6 slide through the top surface of the sedimentation tank 1 and are symmetrically fixed on the top surface of the brush block 21. The brush block 21 is located at the upper left end of the filter plate 18, and the bristles on the brush block 21 are arranged on the vertical surface near the filter plate 18. A bucket-shaped cylinder 2 is fixedly connected to the bottom surface of the sedimentation tank 1. The bucket-shaped cylinder 2 is located below the inclined plates 15, and a sludge removal component is rotatably connected inside the bucket-shaped cylinder 2.

[0024] The water distribution components include a first water distribution plate 17 and a second water distribution plate 14 symmetrically fixed in the sedimentation tank 1. The first water distribution plate 17 is located on one side of the inlet pipe 7, the second water distribution plate 14 is located on one side of the outlet pipe 4, and the inclined plate 15 is located between the first water distribution plate 17 and the second water distribution plate 14. Multiple first hollow tubes 16 are horizontally fixedly sleeved on the side of the first water distribution plate 17, and multiple second hollow tubes 13 are horizontally fixedly sleeved on the side of the second water distribution plate 14. The filter plate 18 is attached to the end of the second hollow tube 13.

[0025] The second water distribution plate 14 has a water cavity inside, and the water cavity is not connected to the second hollow tube 13. The second water distribution plate 14 has multiple water outlet holes 19 connected to the water cavity on the side near the filter plate 18. There is a water outlet hole 19 between two adjacent second hollow tubes 13. The top surface of the second water distribution plate 14 is vertically fixed with a water supply pipe 5 connected to the water cavity. The end of the water supply pipe 5 penetrates the top wall of the sedimentation tank 1. The top surface of the water supply pipe 5 is used to connect to a high-pressure water source.

[0026] The sludge removal component includes a rotating shaft 10 rotatably connected inside a bucket-shaped cylinder 2. A drive motor 3 is vertically fixed to the bottom surface of the bucket-shaped cylinder 2. The output end of the drive motor 3 is connected to the end of the rotating shaft 10. Two support rods 12 are symmetrically fixed to the outer edge of the rotating shaft 10. A scraper 11 is fixedly connected to the end of each of the two support rods 12. The two scraper 11 are symmetrically fixed to the outer edge of the rotating shaft 10 and fit against the side wall and bottom wall of the bucket-shaped cylinder 2. A sludge discharge pipe 9 is obliquely fixed to the side of the bucket-shaped cylinder 2. A sludge discharge valve 8 is fixedly connected to the sludge discharge pipe 9.

[0027] By attaching the filter plate 18 to the end of the second hollow tube 13 in the second water distribution plate 14, it is convenient to filter out fine impurities in the settled water before discharge, preventing impurities from remaining in the settled water due to incomplete filtration. A brush block 21 is connected in a vertical position in the sedimentation tank 1 to facilitate brushing the outside of the filter plate 18, avoiding excessive accumulation of impurities on the filter plate 18, which would cause the holes of the filter plate 18 to be blocked, thus ensuring the water permeability of the filter plate 18. A water cavity is set in the second water distribution plate 14, and multiple water outlets 19 are set on the outside of the second water distribution plate 14. A water supply pipe 5 for connecting a high-pressure water source is fixed on the top surface of the second water distribution plate 14 to facilitate rinsing the filter plate 18 with high-pressure water flow. With the help of the brush block 21, the cleaning effect of the brush block 21 on the filter plate 18 is improved.

[0028] Working principle: During operation, the raw water, after flocculation in the flocculation tank, enters the sedimentation tank 1 through the inlet pipe 7. It then flows through the first hollow pipe 16 on the first distribution plate 17, where it is evenly distributed across the entire cross-section. Upon reaching the middle of the sedimentation tank 1, it encounters the obstruction of the inclined plate 15 and begins flocculation and sedimentation. The sediment naturally settles into the hopper-shaped cylinder 2. The settled raw water is then filtered through the filter plate 18 and evenly distributed across the entire cross-section through the second hollow pipe 13 on the second distribution plate 14. The raw water is discharged from the sedimentation tank 1 through the drain pipe 4. As the hopper-shaped cylinder 2 accumulates more sediment, the drain valve is opened, and the drive motor 3 is started. The drive motor 3 drives the rotating shaft 10 slowly... The slow rotation drives the scraper 11 to rotate synchronously, causing the sediment to be discharged from the hopper 2 through the drain pipe, which facilitates the discharge of sediment. When it is necessary to clean the filter plate 18, the external high-pressure water source is turned on. The external high-pressure water source enters the water chamber in the second water distribution plate 14 through the water supply pipe 5. The water in the water chamber is sprayed onto the filter plate 18 through the water outlet 19. Then, the cylinder 6 drives the brush block 21 to descend, so that the brush block 21 contacts the filter plate 18 and brushes the impurities on the outside of the filter plate 18. At the same time, the high-pressure water flow sprayed from the second water distribution plate 14 washes off the impurities on the filter plate 18 that have been cleaned by the brush block 21.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
