Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a self-cleaning water treatment filtration device. Background Technology

[0002] Water treatment is the process of purifying and treating water through physical, chemical, or biological methods to meet water usage requirements or discharge standards. It is widely used in production and daily life.

[0003] The existing announcement number is CN222605491U, which describes a sewage treatment filtration device. It utilizes a backwashing device to effectively rinse the filter material inside the filtration device. By using the combined action of gas and water, a strong impact force is formed, which effectively removes dirt and blockages from the surface of the filter material. In addition, pulse backwashing technology is used, which uses intermittent high-pressure water and airflow to cause the filter material layer to vibrate and loosen, further improving the cleaning effect.

[0004] While existing water treatment filtration devices can filter wastewater and perform backwashing of filter media, the spray range of the nozzles in the diversion pipe is limited due to the fixed position of the nozzles. This results in relatively incomplete rinsing of the filter media to some extent, affecting the rinsing effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-cleaning water treatment filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-cleaning water treatment filtration device includes a tank body, characterized in that a bottom cover is fixedly connected to the bottom of the tank body, and a first tube, a second tube, and a third tube are fixedly connected through the bottom cover. A fourth tube is rotatably connected to the first tube, and a plurality of one-way valves are fixedly connected to the fourth tube at equal intervals. A housing is fixedly connected between the second and third tubes, and the housing is rotatably connected to the fourth tube. A turbine is fixedly connected to the fourth tube, and the turbine is located inside the housing.

[0008] Preferably, a top cover is fixedly connected to the top of the barrel, a feed inlet is fixedly connected to the top of the top cover, and a three-way valve is fixedly connected to the feed inlet.

[0009] Preferably, the bottom cover is fixedly connected to a discharge port.

[0010] Preferably, filter media is fixedly connected inside the barrel, and the fourth tube is located below the filter media.

[0011] Preferably, the housing is cylindrical and is adapted to the turbine.

[0012] Preferably, the second and third tubes are staggered at one end and the other end of the box.

[0013] Preferably, both the bottom cover and the top cover are conical.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the coordination of the bottom cover, first pipe, second pipe, third pipe, box, fourth pipe, one-way valve and turbine, and by utilizing the connection between the second pipe, third pipe and box, when water passes through the second pipe, box and third pipe, the water flow will drive the worm gear to rotate the third pipe, which in turn will rotate the fourth pipe. Clean water is injected into the first pipe, and the water will be sprayed upward through multiple one-way valves in the fourth pipe to perform a comprehensive backwashing operation on the filter media. This eliminates the blind spots in the backwashing and ensures that every surface of the filter media is impacted by the water flow, greatly improving the backwashing coverage.

[0016] 2. By coordinating the top cover and the three-way valve, and utilizing the characteristics of the three-way valve, it is convenient to discharge water through the inlet of the top cover during backwashing, or to allow wastewater to enter through the inlet for filtration. The single inlet reuse design reduces the number of pipe interfaces, lowers the risk of leakage, improves the system's sealing and reliability, and enhances the practicality and economy of the water treatment equipment.

[0023] 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.

[0024] Example 1, referring to Figures 1 to 5 A self-cleaning water treatment filtration device includes a barrel body 1. The barrel body 1 has a bottom cover 2 fixedly connected to its bottom. The bottom cover 2 is connected through and fixedly to a first pipe body 3, a second pipe body 4, and a third pipe body 5. The first pipe body 3 is rotatably connected to a fourth pipe body 7. Multiple one-way valves 8 are fixedly connected to the fourth pipe body 7 at equal intervals. The one-way valves 8 prevent sewage from entering the fourth pipe body 7. The first pipe body 3, the fourth pipe body 7, and the one-way valves 8 constitute a backwashing pipeline. The second pipe body 4, the third pipe body 5, and a housing 6 constitute a pipeline that drives a turbine 9 to rotate the fourth pipe body 7. The housing 6 is fixedly connected between the second pipe body 4 and the third pipe body 5. The housing 6 is rotatably connected to the fourth pipe body 7. The fourth pipe body 7 is fixedly connected to a turbine 9 located inside the housing 6. Water flow drives the turbine 9 to rotate the fourth pipe body 7, which in turn drives the one-way valves 8 to spray water for backwashing the filter media 13, allowing for comprehensive backwashing of the filter media 13.

[0025] In this embodiment, a top cover 10 is fixedly connected to the top of the barrel 1, and an inlet 11 is fixedly connected to the top of the top cover 10. A three-way valve 12 is fixedly connected to the inlet 11. The three-way valve 12 is used to allow sewage to flow in or to discharge water that is flushed upwards. A discharge port 14 is fixedly connected to the bottom cover 2. Filter media 13 is fixedly connected inside the barrel 1. A fourth pipe 7 is located below the filter media 13. The box 6 is cylindrical and is adapted to the turbine 9. The second pipe 4 and the third pipe 5 are staggered at one end and the other end of the box 6 to form a tangential water inlet and tangential water outlet path, so that the water flow generates a rotating vortex inside the box 6, improving the rotational stability of the turbine 9. Both the bottom cover 2 and the top cover 10 are conical, which can facilitate the guidance and discharge of water.

[0026] The working principle of this embodiment is as follows: When backwashing the filter media 13 is required, cleaning water is injected into the first pipe 3 and water is injected into the second pipe 4. The cleaning water is then conveyed through the first pipe 3 and the fourth pipe 7 and sprayed upwards at multiple one-way valves 8 to backwash the filter media 13. At the same time, the water in the second pipe 4 moves into the housing 6 and then into the third pipe 5 and is discharged from the third pipe 5. The water flow drives the turbine 9 to rotate the fourth pipe 7, thus thoroughly rinsing the filter media 13. Simultaneously, the three-way valve 12 is switched so that the upward-rinsing cleaning water can be discharged through the feed inlet 11 and the three-way valve 12.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
