Description

Technical Field

[0001] This invention relates to the field of water resource treatment equipment technology, specifically a filtration device for recycling river and lake water resources in arid areas. Background Technology

[0002] The ecological environment in arid regions is fragile, and the total amount of river and lake water resources is scarce, with water quality easily affected by wind erosion and soil erosion. Water resource recycling is a key way to alleviate regional water shortage pressure. Currently, filtration devices used for treating river and lake water resources in arid regions generally have the following technical defects: unreasonable filtration layer design, often using single or simple combination filter plates, making it difficult to efficiently remove silt and suspended impurities of different particle sizes from the water, and making it difficult to balance filtration accuracy and efficiency; lack of precise control mechanism for influent flow rate, unable to dynamically adjust the influent rate according to the water volume in the storage tank, easily leading to overflow waste or insufficient water supply; fourth, the structural stability of some devices is poor, and under the complex working conditions of wind erosion and large temperature differences in arid regions, the operational reliability is reduced, and untimely cleaning of filter plates will further affect the filtration effect, resulting in limited water resource recycling rate. These problems seriously restrict the efficient recycling of river and lake water resources in arid regions.

[0003] In order to address the aforementioned problems, this invention proposes a filtration device for recycling river and lake water resources in arid regions. Summary of the Invention

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: A filtration device for recycling river and lake water resources in arid areas, comprising a storage tank 1, characterized in that: symmetrically arranged annular grooves 2 are formed on the upper inner wall of the storage tank 1, with sliders 3 slidably connected within each annular groove 2; a filter tube 4 is fixedly connected to the side of the sliders 3 away from the annular groove 2; a hollow groove 5 is formed on the upper side wall of the filter tube 4; a coarse filter plate 6, a medium filter plate 7, and a fine filter plate 8 are sequentially fixedly connected to the upper inner wall of the filter tube 4; a grooved filter plate 9 is fixedly connected to the lower end of the filter tube 4; several cleaning pipes 10 are fixedly connected to the inner wall of the filter tube 4, communicating with the hollow groove 5; and the cleaning pipes 10 are respectively located above the coarse filter plate 6, the medium filter plate 7, and the fine filter plate 8; symmetrically arranged support pipes 11 are fixedly connected to the upper outer wall of the filter tube 4; the lower end of the support pipes 11 extends into the hollow groove 5; and a vertical pipe 12 is fixedly connected to the upper end of the support pipes 11; the upper wall of the vertical pipe 12 passes through... The bearing is rotatably connected to the wall of the storage box 1, and the top wall of the vertical tube 12 is fixedly sleeved with the first gear 13. The outer wall of the upper side of the storage box 1 is fixedly fixed with the stepper motor 14, and the output end of the stepper motor 14 is fixedly connected with the second gear 15. The second gear 15 is meshed with the first gear 13. The outer wall of one side of the storage box 1 is fixedly connected with the pump body 16 through the bracket. The lower end of the pump body 16 is fixedly connected with the inlet pipe 17 with a filter screen at the lower end. The lower end of the inlet pipe 17 is connected to the bottom end of the storage box 1. The upper end of the pump body 16 is fixedly connected with the discharge pipe 18. The upper end of the discharge pipe 18 is rotatably connected to the vertical tube 12 through the rotating joint. The side wall of the storage box 1 away from the inlet pipe 17 is fixedly connected with the feed pipe 24. The slider 3 and the cleaning pipe 10 are arranged in a circular array. Electric valves are installed on the walls of the inlet pipe 17 and the feed pipe 24. The lower end of the storage box 1 is fixedly connected with symmetrically arranged support legs.

[0018] When in use, first fix the device to a flat ground using the symmetrical support legs at the bottom of the storage box 1 to ensure the overall stability of the device and adapt to the working conditions of arid areas with frequent sandstorms and large temperature differences; open the electric valves on the walls of the inlet pipe 17 and the discharge pipe 24. Start the stepper motor 14 at the top of the storage box 1. The output of the stepper motor 14 drives the second gear 15 to rotate. The second gear 15 meshes with the first gear 13 to drive the vertical tube 12 to rotate around the bearing. The vertical tube 12 drives the filter tube 4 to rotate synchronously through the support tube 11. The circular array sliders 3 on both sides of the filter tube 4 slide along the annular groove 2 to ensure the stability of the filter tube 4 during rotation. After the filtered water enters the filter pipe 4, it passes through the coarse filter plate 6, the medium filter plate 7, and the fine filter plate 8 in sequence to remove mud and suspended impurities of different particle sizes. Finally, it passes through the grooved filter plate 9 to complete the fourth stage of filtration, achieving a high-precision and high-efficiency filtration effect. During the filtration process, the pump body 16 is started, and the water that has been initially filtered at the bottom of the storage tank 1 is drawn into the discharge pipe 18 through the inlet pipe 17 with a filter screen at the bottom, and then transported to the vertical pipe 12 through the rotating joint. Subsequently, it flows into the hollow tank 5 through the support pipe 11, and is finally sprayed out by several circular array cleaning pipes 10 to clean the coarse filter plate 6, the medium filter plate 7, and the fine filter plate 8 in real time, reducing filter plate clogging. After filtration is completed, the clean water after four stages of filtration is discharged through the discharge pipe 24 for subsequent recycling; the stepper motor 14, pump body 16 and all electric valves are closed to complete a single filtration operation.

[0019] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a feed pipe 19 with an internal water level sensor is fixedly connected to one side of the upper end of the storage box 1. The inner wall of the feed pipe 19 is rotatably connected to a rotating rod 20 via a bearing. The rotating rod 20 is fixedly connected to arc-shaped baffles 21 of different lengths. One side of the rotating rod 20 extends to the outer wall of the feed pipe 19 and is fixedly connected to a crank 22. The other side of the crank 22 is connected to an electric telescopic rod 23 via a hinge. The upper end of the electric telescopic rod 23 is rotatably connected to the outer wall of the storage box 1 via a rotating shaft.

[0020] When in use, the device is fixed and initially prepared in the same way as in Embodiment 1. The river and lake water resources to be filtered are connected to the feed pipe 19 with the built-in water volume sensor. The water volume sensor detects the water level data in the storage tank 1 in real time and feeds the signal back to the external controller. The controller adjusts the extension and retraction of the electric telescopic rod 23 according to the water level data: when the water level in the storage tank 1 is insufficient, the electric telescopic rod 23 extends, driving the rotating rod 20 to rotate via the crank 22, causing the arc-shaped baffles 21 of different lengths on the rotating rod 20 to rotate and change, expanding the flow cross section of the feed pipe 19 and increasing the water inlet rate; when the water level in the storage tank 1 is close to the threshold, the electric telescopic rod 23 retracts, causing the arc-shaped baffles 21 to open at a smaller angle, reducing the flow cross section and lowering the water inlet rate. By adjusting the arc-shaped baffles 21 of different specifications, overflow waste or insufficient water supply can be avoided.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
