Description

Technical Field

[0001] This utility model relates to wastewater treatment technology, specifically to a water distribution device for an inclined sedimentation tank. Background Technology

[0002] Wastewater sedimentation treatment separates suspended solids, such as silt, organic debris, and microorganisms, from water using gravity. Utilizing the density difference between suspended solids and water, the water flow slows down, causing particles to settle to the bottom. Sedimentation reduces water turbidity and provides pretreatment for subsequent processes. Sedimentation typically requires a sedimentation tank, and inclined sedimentation tanks are key equipment in the water treatment field. Their core principle is based on the "shallow sedimentation" theory. By setting up dense inclined plates or tubes within the sedimentation zone, the water flow is divided into thin layers, significantly shortening the particle settling distance and increasing the effective sedimentation area. This design increases treatment efficiency by 3-5 times and reduces the footprint by more than 50%, making it widely used in water supply treatment, industrial wastewater treatment, and primary wastewater treatment.

[0003] However, in the existing inclined sedimentation tanks, wastewater is usually directly introduced into the sedimentation tank, causing the wastewater to flow in one place. This results in the wastewater flowing randomly within the sedimentation tank, preventing it from flowing evenly towards the inclined plates for sedimentation. This easily affects the sedimentation effect and causes considerable inconvenience to the user. Utility Model Content

[0004] The purpose of this invention is to provide a water distribution device for an inclined sedimentation tank, which solves the problem that in the prior art, sewage is usually directly introduced into the sedimentation tank, causing the sewage to flow in one place. This results in the sewage flowing randomly in the sedimentation tank, preventing the sewage from flowing evenly to the inclined plate for sedimentation, which easily affects the sedimentation effect and causes many inconveniences for use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water distribution device for an inclined sedimentation tank, comprising a sedimentation mechanism and a water distribution mechanism assembled on the top of the sedimentation mechanism, the sedimentation mechanism comprising a sedimentation tank, an overflow trough fixedly installed on the periphery of the sedimentation tank, an installation frame inserted into the interior of the sedimentation tank, an inclined sedimentation plate inserted into the interior of the installation frame, and a sludge collection hopper fixedly installed at the bottom of the sedimentation tank;

[0006] The water distribution mechanism includes a movable seat that is slidably installed on the top of the sedimentation tank. A water inlet hopper is fixedly installed on the top of the movable seat, and a diversion pipe is fixedly installed on the bottom of the water inlet hopper. A water distribution pipe is threadedly connected to the bottom of the diversion pipe, and a water outlet is connected to the end of the water distribution pipe. The water outlet is flat.

[0007] Furthermore, the sedimentation tank is provided with an overflow hole corresponding to the overflow tank on its periphery, and the bottom of the overflow tank is connected to a drain pipe.

[0008] Furthermore, the bottom of the sedimentation tank is provided with a sedimentation port that communicates with the sludge collection hopper, and a sewage pipe is fixedly installed at the bottom of the sludge collection hopper.

[0009] Furthermore, a threaded rotating rod is rotatably mounted on the top of the sedimentation tank, and the movable seat and the threaded rotating rod are threadedly connected by a threaded seat.

[0010] Furthermore, the movable seat and the sedimentation tank are slidably installed together via a sliding block, and the top of the sedimentation tank is provided with a track groove for the sliding block to slide.

[0011] Furthermore, the diversion pipe and the water inlet hopper are fixedly installed together by a fixed bracket, and the top of the diversion pipe and the bottom of the water inlet hopper are connected to each other.

[0012] Furthermore, the diversion pipe and the water distribution pipe are connected by a threaded sleeve, and the bottom of the diversion pipe is equipped with a threaded opening for the threaded sleeve to engage.

[0013] Compared with the prior art, the inclined sedimentation tank water distribution device provided by this utility model, by setting up a water distribution mechanism, can conveniently introduce sewage into multiple water distribution pipes through the diversion pipes. Through the flat water outlet, the water can be evenly introduced into the bottom of the sedimentation tank in a waterfall-like manner. Through the collision of the water flow with the bottom wall of the sedimentation tank, the water flow can be reflected to the sedimentation inclined plate, so that the water flow can flow evenly upward along the sedimentation inclined plate. This allows impurities in the sewage to quickly settle onto the sedimentation inclined plate, avoiding the situation where the sewage is concentrated in one place and the flow direction becomes scattered, thus improving the sedimentation effect.

[0014] The movable seat allows it to slide along the top of the sedimentation tank, moving the entire water distribution mechanism. It adjusts the distance between the outlet and the sedimentation plate according to the wastewater concentration. When the wastewater concentration is high, the outlet is closer to the sedimentation plate, increasing the speed at which water flows into the plate and causing impurities to settle quickly. When the wastewater concentration is low, the distance between the outlet and the sedimentation plate is increased, slowing the flow and preventing lighter impurities from being washed out of the plate, thus improving the sedimentation effect.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 6 As shown:

[0026] Example 1:

[0027] This utility model provides a water distribution device for an inclined sedimentation tank, including a sedimentation mechanism 1 and a water distribution mechanism 2 assembled on the top of the sedimentation mechanism 1. The sedimentation mechanism 1 includes a sedimentation tank 11, an overflow trough 12 is fixedly installed on the periphery of the sedimentation tank 11, an installation frame 18 is inserted into the inside of the sedimentation tank 11, an inclined sedimentation plate 19 is inserted into the inside of the installation frame 18, and a sludge collection hopper 14 is fixedly installed at the bottom of the sedimentation tank 11.

[0028] The water distribution mechanism 2 includes a movable seat 23 that is slidably installed on the top of the sedimentation tank 11. A water inlet hopper 21 is fixedly installed on the top of the movable seat 23. A diversion pipe 22 is fixedly installed on the bottom of the water inlet hopper 21. A water distribution pipe 25 is threadedly connected to the bottom of the diversion pipe 22. A water outlet 26 is connected to the end of the water distribution pipe 25. The water outlet 26 is flat.

[0029] As can be seen from the above, when using this device, it is placed in a suitable position, and the wastewater that needs to be settled is introduced into the inlet hopper 21, allowing the wastewater to flow into the diversion pipe 22. The diversion pipe 22 can conveniently guide the wastewater into multiple distribution pipes 25, and the outlet head 26 guides the water flow into the sedimentation tank 11. The outlet head 26 is flat, allowing the outgoing water to flow in a waterfall-like manner. When the water flow comes into contact with the bottom wall of the sedimentation tank 11, it can create a reflection effect. The outlet head 26 and the bottom of the sedimentation tank 11 are used to reflect the water flow. The walls are inclined at a certain angle, which allows the reflected water flow to flow towards the sedimentation inclined plate 19. The water flow can flow evenly upward along the sedimentation inclined plate 19, and the heavier impurities can fall onto the sedimentation inclined plate 19 for sedimentation by gravity, which effectively improves the sedimentation effect. The sedimented impurities can slide down the sedimentation inclined plate 19 into the sludge collection hopper 14 for collection, which is convenient for subsequent sludge removal and cleaning. The clearer water after sedimentation can flow into the overflow tank 12 for collection, which is convenient for the clean water to be exported and reused.

[0030] The movable seat 23 can move left and right along the top of the sedimentation tank 11, which can drive the entire water distribution mechanism 2 to move synchronously. The distance between the outlet head 26 and the sedimentation inclined plate 19 can be changed according to the concentration of the sewage. When the sewage concentration is high, the outlet head 26 can be moved closer to the sedimentation inclined plate 19, which can shorten the distance between the outlet head 26 and the sedimentation inclined plate 19 and increase the speed at which the water flows into the sedimentation inclined plate 19, so that more impurities in the sewage can be settled quickly. When the sewage concentration is low, the outlet head 26 can be moved away from the sedimentation inclined plate 19, which can increase the distance between the outlet head 26 and the sedimentation inclined plate 19 and slow down the speed at which the water flows into the sedimentation inclined plate 19, so that lighter impurities in the sewage can be settled slowly and prevent lighter impurities in the sewage from being washed out of the sedimentation inclined plate 19 with the water flow, which brings more convenience to the sedimentation effect.

[0031] From the appendix Figure 3 It can be seen that the sedimentation tank 11 has an overflow hole 17 corresponding to the overflow tank 12 on its outer periphery, and the bottom of the overflow tank 12 is connected to a drain pipe 13.

[0032] As can be seen from the above, the relatively clear water at the top after sedimentation can flow into the overflow tank 12 through the overflow hole 17 for collection. The water in the overflow tank 12 can be easily discharged through the drain pipe 13, making it convenient to use or carry out subsequent purification operations according to usage needs.

[0033] For details, please refer to the appendix. Figure 2 and attached Figure 4 As shown, the bottom of the sedimentation tank 11 is provided with a sedimentation port 111 that communicates with the sludge collection hopper 14, and a sewage pipe 15 is fixedly installed at the bottom of the sludge collection hopper 14.

[0034] As can be seen from the above, the sedimentation port 111 can correspond to the sedimentation inclined plate 19, so that the sediment sliding off the sedimentation inclined plate 19 can be introduced into the sludge collection hopper 14 for collection. The sediment in the sludge collection hopper 14 can be conveniently discharged through the sewage pipe 15, which facilitates the cleaning operation of the sludge collection hopper 14.

[0035] For details, please refer to the appendix. Figure 1 Appendix Figure 3 and attached Figure 5 As shown, a threaded rod 16 is rotatably mounted on the top of the sedimentation tank 11, and the movable seat 23 is threadedly connected to the threaded rod 16 via a threaded seat 27.

[0036] As can be seen from the above, the threaded rod 16 and the threaded seat 27 are threadedly engaged, which allows the threaded rod 16 to rotate and the threaded seat 27 to move along the threaded rod 16. This allows the movable seat 23 to slide left and right along the top position of the sedimentation tank 11, and facilitates the control of the distance between the outlet head 26 and the sedimentation inclined plate 19.

[0037] Working principle: By moving the movable seat 23 left and right, the distance between the outlet head 26 and the sedimentation inclined plate 19 is adjusted to a suitable distance. By introducing sewage into the inlet hopper 21, the sewage can be introduced into the diversion pipe 22. Through the diversion pipe 22, the sewage can be introduced into multiple distribution pipes 25. The outlet head 26 introduces the sewage into the interior of the sedimentation tank 11. The reflection effect generated when the sewage comes into contact with the bottom wall of the sedimentation tank 11 can easily reflect the water flow to the sedimentation inclined plate 19, so that the water flow can flow evenly along the sedimentation inclined plate 19 in a waterfall-like manner. This allows the impurities in the sewage to be evenly settled on the sedimentation inclined plate 19. Through gravity, the sediment can slide down the sedimentation inclined plate 19 and fall into the sludge collection hopper 14. After sedimentation, the clearer water on the upper layer can flow into the overflow tank 12 for collection and easy export for use.

[0038] Example 2:

[0039] Reference Appendix Figure 4 and attached Figure 5 As shown, the movable seat 23 is slidably installed with the sedimentation tank 11 via a sliding block 24, and the top of the sedimentation tank 11 is provided with a track groove 110 for the sliding block 24 to slide.

[0040] As can be seen from the above, the sliding block 24 can slide along the track groove 110. The track groove 110 can limit the sliding block 24, so that the moving seat 23 can slide left and right stably without deviation.

[0041] Reference Appendix Figure 5 As shown, the diversion pipe 22 and the water inlet hopper 21 are fixedly installed together by a fixing bracket 28, and the top of the diversion pipe 22 and the bottom of the water inlet hopper 21 are connected to each other.

[0042] As can be seen from the above, the fixed bracket 28 can be used to fix the diversion pipe 22 in a convenient way, so as to prevent the diversion pipe 22 from shaking and to ensure that the sewage in the inlet hopper 21 can be stably introduced into the diversion pipe 22.

[0043] Reference Appendix Figure 6 As shown, the diversion pipe 22 and the water distribution pipe 25 are connected by a threaded sleeve 210. The bottom of the diversion pipe 22 is equipped with a threaded port 29 for the threaded sleeve 210 to engage.

[0044] As can be seen from the above, when the water distribution pipe 25 is aligned with the threaded port 29, the threaded sleeve 210 can be rotated to connect with the threaded port 29, which facilitates the installation of the water distribution pipe 25 and also makes it easy to disassemble the water distribution pipe 25. This allows the staff to clean the inner wall of the water distribution pipe 25 later, preventing impurities from accumulating and adhering to the inner wall of the water distribution pipe 25 and causing blockages and poor water flow, thus bringing more convenience to the maintenance work.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
