Description

Technical Field

[0001] This utility model relates to agricultural irrigation equipment, specifically to a dual-tank agricultural irrigation water filtration device with backwashing. Background Technology

[0002] Agricultural irrigation water is generally drawn from natural water sources such as streams and springs, resulting in a significant amount of impurities such as silt and small stones. Furthermore, fertilizers and baking powders are often added to the irrigation water, which also typically contain particulate impurities. To prevent these impurities from clogging irrigation pipes and outlets, the irrigation water needs to be filtered first. Traditional filtration devices usually consist of a filter tank with filter components inside. Irrigation water is fed into the tank, filtered by the components, and then discharged. However, once a certain amount of impurities accumulates inside the tank, the filter components need to be disassembled and cleaned, which is cumbersome, time-consuming, and labor-intensive. Moreover, the limited capacity of a single filter tank restricts its filtration efficiency, making it difficult to achieve high-efficiency water supply. While some self-cleaning filtration devices have emerged on the market, their overall structure is very complex, and in actual use, the cleaning effect on internal impurities is poor, resulting in a poor user experience. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a dual-tank agricultural irrigation water filtration device with backwashing for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A dual-tank agricultural irrigation water filtration device with backwashing includes an inlet pipe and an outlet pipe. It is characterized by further including a first filter tank and a second filter tank. Both the first and second filter tanks are equipped with filter components, such that filtered impurities are located between the filter components and the inner walls of the filter tanks. The inlet pipe is connected to the first filter tank via a first guide pipe and to the second filter tank via a second guide pipe. The outer wall of the first filter tank has a first waste pipe communicating with its inner cavity, and the outer wall of the second filter tank has a second waste pipe communicating with its inner cavity. The first filter tank is connected to the outlet pipe via a third guide pipe, and the second filter tank is connected to the outlet pipe via a fourth guide pipe. A first on / off control valve is provided corresponding to the first guide pipe, a second on / off control valve is provided corresponding to the second guide pipe, a third on / off control valve is provided corresponding to the first waste pipe, and a fourth on / off control valve is provided corresponding to the second waste pipe.

[0006] The inlet pipe has inlets at both ends, and the outlet pipe has outlets at both ends.

[0007] A reinforcing pipe is installed between the inlet pipe and the outlet pipe, with both ends of the reinforcing pipe tightly attached to the outer walls of the inlet pipe and the outlet pipe.

[0008] The first on / off control valve, the second on / off control valve, the third on / off control valve, and the fourth on / off control valve are manual ball valves.

[0009] The filter assembly includes a filter screen, which forms a structure with a single opening, and the single opening is connected to the third and fourth guide pipes.

[0010] The filter screen is formed into a cylindrical shape, and the single opening is located at one end of the cylindrical shape.

[0011] The aforementioned technical solution features a dual-tank agricultural irrigation water filtration device with backwashing. By setting up two filter tanks and connecting the inlet pipe to the filter tanks via first and second guide pipes, and connecting the filter tanks to the outlet pipe via third and fourth guide pipes, simultaneous filtration by both tanks can be achieved, effectively improving filtration efficiency. Furthermore, by installing on / off control valves on the first and second guide pipes and the first and second waste discharge pipes, irrigation water can be reverse-flowed into a single filter tank through control of the valves, thereby backwashing the internal filter components and discharging them through the waste discharge pipe. This eliminates the need to disassemble the filter components, making cleaning convenient. The use of high-pressure irrigation water ensures effective cleaning and rapid removal of impurities from the tanks; a single backwash of the filter components can be completed in just 4-5 seconds.

[0018] As shown in the figure, the dual-tank agricultural irrigation water filtration device with backwashing disclosed in this utility model includes an inlet pipe 1 and an outlet pipe 7, as well as a first filter tank 12 and a second filter tank 15. Both the first and second filter tanks are equipped with filter components, so that the filtered impurities are located between the filter components and the inner walls of the filter tanks. The inlet pipe 1 is connected to the first filter tank 12 through a first guide pipe 2, and the inlet pipe 1 is connected to the second filter tank 15 through a second guide pipe 3. The outer wall of the first filter tank 12 is provided with a connection to its inner cavity. The first waste pipe 11 and the second filter tank 15 are provided with a second waste pipe 14 communicating with their inner cavity on the outer side wall. The first filter tank 12 is connected to the water outlet pipe 7 through the third guide pipe 8 and the second filter tank 15 is connected to the water outlet pipe 7 through the fourth guide pipe 16. A first on / off control valve 9 is provided corresponding to the first guide pipe 2, a second on / off control valve 17 is provided corresponding to the second guide pipe 3, a third on / off control valve 10 is provided corresponding to the first waste pipe 11, and a fourth on / off control valve 13 is provided corresponding to the second waste pipe 14.

[0019] Furthermore, both ends of the inlet pipe 1 are equipped with inlets 4, and both ends of the outlet pipe 7 are equipped with outlets 6. This structure facilitates water inlet and outlet on both sides, further improving the flow efficiency of irrigation water. When only water inlet or outlet on one side is needed, only one inlet or outlet needs to be blocked.

[0020] Furthermore, a reinforcing pipe 5 is installed between the inlet pipe 1 and the outlet pipe 7. The two ends of the reinforcing pipe 5 are closely attached to the outer walls of the inlet pipe 1 and the outlet pipe 7, which can realize the positioning between the inlet pipe 1 and the outlet pipe 7 and ensure the stability of the position of the inlet and outlet pipes.

[0021] Furthermore, the first on / off control valve 9, the second on / off control valve 17, the third on / off control valve 10, and the fourth on / off control valve 13 are manual ball valves. The opening and closing of each valve can be controlled by manually operating a wrench, thus controlling the on / off state of each pipeline. Of course, in addition to manual ball valves, manual gate valves, butterfly valves, etc., can also be used, or solenoid valves can be used, with the opening and closing of the solenoid valves remotely controlled by a controller, further enhancing the automation level of this device.

[0022] Furthermore, the filter assembly includes a filter screen 18, which forms a structure with a single opening 21. This single opening 21 is connected to the third and fourth guide pipes. Specifically, a connector 19 is provided inside the filter tank, with its tubular portion 20 connected to the third and fourth guide pipes. The single opening 21 of the filter screen 18 is tightly pressed against the connector 19. The filter screen 18 is formed into a cylindrical shape, with the single opening 21 located at one end of the cylindrical shape. This structure effectively increases the filter area of ​​the screen, allowing more impurities to be filtered per unit time, thereby effectively improving its filtration performance.

[0023] The working principle of this utility model is as follows: When irrigation water needs to be filtered, the first on / off control valve 9 and the second on / off control valve 17 are opened, and the third on / off control valve 10 and the fourth on / off control valve 13 are closed. Irrigation water enters through the inlet pipe 1, and then enters the first and second filter tanks through the first and second guide pipes. It is then filtered by the filter assembly, so that impurities remain between the filter screen 18 and the inner wall of the filter tank. The filtered irrigation water flows out from the single opening 21 formed by the filter screen 18 and flows through the connector 19 and the third and fourth guide pipes into the outlet pipe 7 for subsequent irrigation. When the filter assembly in the first filter tank 12 needs to be flushed and waste discharged, the second on / off control valve 17 and the third on / off control valve 10 are opened, and the first on / off control valve 9 and the fourth on / off control valve 13 are closed. At this time, irrigation water will only flow through the inlet pipe 1 and the second on / off control valve 13. The water enters the second filter tank 15 through the guide pipe 3 for filtration. The filtered irrigation water then flows out through the fourth guide pipe 16 into the outlet pipe 7. When the irrigation water flows to the third guide pipe 8, due to the high water pressure, some of the irrigation water will flow back into the first filter tank 12 through the third guide pipe 8. At this time, the irrigation water will backwash the filter screen in the first filter tank 12 and push the impurities remaining in the tank to the first waste discharge pipe 11 for discharge, thus achieving the rinsing and waste discharge of the filter components. Similarly, when it is necessary to rinse and discharge the filter components in the second filter tank 15, the first on / off control valve 9 and the fourth on / off control valve 13 are opened, and the second on / off control valve 17 and the third on / off control valve 10 are closed, so that the water flow in the second filter pipe 15 can be reversed, thereby rinsing the filter screen inside and discharging the impurities inside.

[0024] This invention features a structure with two filter tanks. First and second guide pipes connect the inlet pipe to the filter tanks, while third and fourth guide pipes connect the filter tanks to the outlet pipes. This allows for simultaneous filtration in both tanks, significantly improving filtration efficiency. Furthermore, control valves on the first and second guide pipes and the first and second waste discharge pipes allow for reverse irrigation of individual filter tanks. This reverse flushing of the internal filter components eliminates the need for disassembly, making cleaning convenient. The high-pressure irrigation water ensures effective cleaning and rapid removal of impurities from the tanks. A single reverse flush of the filter components can be completed in just 4-5 seconds.
