Description

Technical Field

[0001] This utility model relates to the field of sedimentation device technology, and more specifically, to a self-cleaning sedimentation device. Background Technology

[0002] Sedimentation devices are equipment that use gravity to separate solid particles suspended in a liquid from the liquid. They are widely used in wastewater treatment, chemical production, and metallurgy. Their core principle is to use gravity to allow solid particles to settle in a specific space, thereby achieving solid-liquid separation. This is of great significance for improving fluid purification efficiency and ensuring the stable operation of subsequent processes. According to the shallow pool sedimentation theory, sedimentation efficiency depends on the sedimentation area rather than the pool depth. By rationally designing the sedimentation zone structure, particle settling conditions can be optimized, such as shortening the settling distance, maintaining laminar flow, and promoting particle flocculation, thereby significantly improving the separation effect.

[0003] However, in long-term operation, existing sedimentation devices suffer from imperfect structural design of the sedimentation space, resulting in long particle settling paths and difficulty in further improving overall treatment efficiency. At the same time, local turbulence easily occurs in the water flow within the device, interfering with the stable settling of particles, and the collision and flocculation effect between particles is poor, making it difficult to form an efficient "dynamic sludge layer." The stability and continuity of solid-liquid separation need to be improved, and it cannot fully meet the needs of modern industrial production and wastewater treatment for high-efficiency separation equipment.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] Please see Figures 1-6 The system includes two substrates 1. Three rows of connecting plates 15 are arranged inside the two substrates 1 on the side close to each other. Multiple inclined plates 16 are fixedly connected to the side of each of the three connecting plates 15 that are close to each other. The side of the two connecting plates 15 that are far from each other is fixedly connected to the side of the two substrates 1 that are close to each other. Multiple equidistant guide plates 18 are fixedly connected to the two inclined surfaces on the outer surface of each inclined plate 16. Multiple positioning plates 17 are fixedly connected to the outer surface of each connecting plate 15. The bottom surface of each inclined plate 16 is fixedly connected to the upper surface of the two positioning plates 17. The height distance between the upper and lower inclined plates 16 is 60 mm. The included angle of the inclined plates 16 is 60 degrees. The included angle of the bottom inclined surface of the inclined plate 16 is 150 degrees. The width of the substrate 1 is 30 mm and the width of the connecting plate 15 is 20 mm.

[0028] Specifically, the overall structure is supported by two base plates 1, and three rows of connecting plates 15 are connected between the base plates 1 to form a stable frame. Each set of three connecting plates 15 together fixes multiple inclined plates 16. The positioning plate 17 supports the inclined plates 16 from the bottom to ensure that they are installed firmly. The vertical spacing of the inclined plates 16 is 60mm, which meets the shallow requirements of the shallow pool sedimentation theory. This can shorten the particle settling distance and increase the settling area. The angle design of the inclined plates 16, together with the guide plates 18 on their surface, can guide the water flow and the direction of the particles, reduce turbulence interference, promote particle collision and flocculation, and solve the problems of long settling paths and low efficiency in traditional devices.

[0029] Please see Figures 1-6 Two substrates 1 are fixedly connected to a fixed frame 12 on their opposite sides. A centrifugal pump 19 and a solenoid valve 7 are fixedly connected to the left side of one of the substrates 1. The input and output ends of the centrifugal pump 19 are fixedly connected to a first water inlet pipe 2 and a drain pipe 8, respectively. The end of the drain pipe 8 away from the centrifugal pump 19 is fixedly connected to an arc-shaped high-pressure pipe 9. Multiple rotating water nozzles 11 are fixedly connected to the bottom of the outer surface of the arc-shaped high-pressure pipe 9. The outer surface of the drain pipe 8 is fixedly connected to the inner wall of the solenoid valve 7.

[0030] Specifically, the overall structural stability is enhanced by the fixing frame 12 on the outside of the two base plates 1. The centrifugal pump 19 on the left side of the base plate 1 draws water through the first water inlet pipe 2, delivers it to the bow-shaped high-pressure pipe 9 through the drain pipe 8, and then sprays it out by the rotating spray head 11. The solenoid valve 7 controls the opening and closing of the drain pipe 8. With the help of the inclined plate 16, the inclined plate 16 can be rinsed during the sedimentation process or in the interval, solving the problem of mud accumulation on the inclined plate 16.

[0031] Please see Figures 1-6 Three fixing brackets 10 are fixedly connected to the top of the outer surface of the bow-shaped high-pressure pipe 9, and the inner wall of each fixing bracket 10 is fixedly connected to the outer surface of the fixing frame 12.

[0032] Specifically, the fixed bracket 10 is connected to the fixed frame 12 to ensure that the bow-shaped high-pressure pipe 9 and the rotating spray head 11 are firmly installed, preventing them from shaking under the impact of water flow. This ensures that the rotating spray head 11 can accurately rinse the inclined plate 16, ensuring a stable cleaning effect and solving the problem of uneven rinsing caused by unstable installation of the spray system.

[0033] Please see Figures 1-6 A filter cylinder 3 is fixedly connected to the bottom outer surface of the first water inlet pipe 2. A second water inlet pipe 4 is fixedly connected to the bottom of the filter cylinder 3. A fixing ring 5 is fixedly connected to the bottom outer surface of the first water inlet pipe 2 and the top outer surface of the second water inlet pipe 4. The sides of the two fixing rings 5 ​​that are close to each other are fixedly connected to the ends of the filter cylinder 3 that are far away from each other. A coarse stainless steel filter screen 21 and a fine stainless steel filter screen 20 are fixedly connected to the inner wall of the filter cylinder 3.

[0034] Specifically, the first water inlet pipe 2 and the second water inlet pipe 4 are connected to the filter cylinder 3 through the fixing ring 5, so that the water flow first passes through the coarse stainless steel filter screen 21 and the fine stainless steel filter screen 20 in the filter cylinder 3 to remove impurities in the water, prevent impurities from entering the centrifugal pump 19, the drain pipe 8 and the rotating spray head 11 and causing blockage, ensure the normal operation of the spray system, and solve the problem of equipment failure caused by impurities in the rinsing water.

[0035] Please see Figures 1-6 Two stabilizing seats 6 are fixedly connected to the outer surface of the filter cartridge 3. The right side of each stabilizing seat 6 is fixedly connected to the left side of one of the base plates 1. A timer 13 and a PLC controller 14 are fixedly connected to the left side of one of the base plates 1. The PLC controller 14 is electrically connected to the centrifugal pump 19, the solenoid valve 7 and the timer 13 through wires.

[0036] Specifically, the filter cartridge 3 is fixed to the base plate 1 by the stabilizing seat 6 to enhance the stability of the filter structure. The timer 13 on the base plate 1 sets the rinsing time. The PLC controller 14 receives the signal from the timer 13 and controls the start and stop of the centrifugal pump 19 and the solenoid valve 7 to realize automatic timed rinsing without manual operation, ensuring that the inclined plate 16 is clean for a long time, maintaining the sedimentation efficiency, and solving the problems of inconvenience and untimely cleaning by manual cleaning.

[0037] Working principle:

[0038] In use, two base plates 1 provide support for the overall structure, and three rows of connecting plates 15 connect between the base plates 1 to form a stable frame. Each set of three connecting plates 15 together fixes multiple inclined plates 16. Positioning plates 17 support the inclined plates 16 from the bottom to ensure their stable installation. The vertical spacing of the inclined plates 16 is 60mm, which meets the shallow layer requirements of the shallow pool sedimentation theory, shortening the particle settling distance and increasing the sedimentation area. The angle design of the inclined plates 16, combined with the guide plates 18 on their surface, can guide the water flow and particle direction, reduce turbulence interference, and promote particle collision and flocculation. When it is necessary to clean the inclined plates 16, the centrifugal pump 19 on the left side of the base plate 1 draws water through the first inlet pipe 2, delivers it through the drain pipe 8 to the arc-shaped high-pressure pipe 9, and then sprays it out by the rotating spray head 11. The solenoid valve 7 controls the opening and closing of the drain pipe 8, which can be used to rinse the inclined plates 16 during the sedimentation process or in the intervals. The three fixing brackets 10 on the top of the arc-shaped high-pressure pipe 9 hold it in place. The fixed frame 12 is connected to ensure that the bow-shaped high-pressure pipe 9 and the rotating spray head 11 are firmly installed, preventing them from shaking under the impact of water flow and ensuring that the rotating spray head 11 can accurately rinse the inclined plate 16. The first water inlet pipe 2 and the second water inlet pipe 4 are connected to the filter cylinder 3 through the fixing ring 5, so that the water flow first passes through the coarse stainless steel filter screen 21 and the fine stainless steel filter screen 20 in the filter cylinder 3 to remove impurities in the water and prevent impurities from entering the centrifugal pump 19, drain pipe 8 and rotating spray head 11 and causing blockage. The filter cylinder 3 is fixed to the base plate 1 through the stabilizing seat 6 to enhance the stability of the filtration structure. The timer 13 on the base plate 1 sets the rinsing time. The PLC controller 14 receives the signal of the timer 13 and controls the start and stop of the centrifugal pump 19 and the solenoid valve 7 to realize automatic timed rinsing, which solves the problems of long sedimentation path, low efficiency, mud accumulation on the inclined plate 16, unstable spray system and inconvenience of manual cleaning in traditional devices.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
