Description

Technical Field

[0001] This invention relates to the field of agricultural equipment systems, and more specifically, to a high-efficiency backwash filter that can cope with complex water quality changes. Background Technology

[0002] Drip irrigation, as an effective water-saving irrigation method, has been widely promoted and applied in countries around the world.

[0003] However, due to the structural limitations of the terminal capillary tubes and drip irrigation orifices, drip irrigation technology has high requirements for water quality, and irrigation water needs to be filtered before entering the drip irrigation pipeline. During the filtration process, the drip irrigation filter quickly accumulates a large amount of impurities and sand, which needs to be dealt with as soon as possible.

[0004] Therefore, high-efficiency backwash filters that can cope with complex water quality changes have a broad application prospect and a strong sense of urgency and demand. In addition, some existing backwashing devices perform direct end impact, but this backwashing method can only perform unilateral cleaning and the flushing direction and angle are singular, thus having the defect of flushing blind spots.

[0005] To address this, we propose a high-efficiency backwash filter to cope with complex water quality changes. Summary of the Invention

[0006] To improve or even solve at least one of the problems in the prior art, this invention proposes a high-efficiency backwash filter and its application in response to complex water quality changes.

Each end of the first fastener is provided with a fixing hole, and a fastening bolt is threaded into the fixing hole. The second fastener is arranged in the middle of the main pipe, and a rotating handle is inserted into the middle of the upper end through a connecting rod. A first strong magnetic block is provided at the lower end of the connecting rod.

[0012] The backflush module includes an installation component and a filter component. The backflush module is snapped into a rotating groove. The installation component includes an upper installation part and a lower installation part. Both the upper and lower installation parts are arc-shaped installation parts with a slot on the center side. Each slot has a latch on its inner sidewall. The filter component includes a vertical filter screen, a horizontal filter screen, and a cross filter screen. The vertical filter screen, horizontal filter screen, and cross filter screen are equally spaced and have vertical sub-slots and latch slots at both the top and bottom. A second strong magnet is fixedly connected to the top of the upper installation part.

[0013] The upper mounting component is disposed in a rotating groove near the first strong magnetic block. A third strong magnetic block and a fourth strong magnetic block are respectively embedded in the two centrally symmetrical ends of the rotating handle. A first guide plate and a second guide plate are hinged to the inner wall of the main pipe of the backflushing body. The two guide plates are symmetrically arranged about the filter assembly and are disposed on the side of the inner wall of the main pipe of the backflushing body near the rotating handle. A fifth strong magnetic block is embedded in the suspended end of each of the two guide plates.

[0014] Furthermore, the main pipe is a high-strength plastic pipe, and the thinnest part of the main pipe is not less than 3mm thick.

[0015] Furthermore, the extension connecting piece is a duckbill-shaped metal piece, with two pieces symmetrically arranged on each side of the main pipe, and the central angle of the extension connecting piece is not less than 30°.

[0016] Furthermore, the rotating groove is provided with two symmetrical grooves on the top and bottom, and each groove has a flat bottom and an arc surface.

[0017] Furthermore, two cylindrical rubber rings are provided parallel to each other between the first fastener and the extension connecting piece. The first fastener is a strip-shaped metal fastener, and the second fastener is a strip-shaped plastic fastener.

[0018] Furthermore, anti-slip grooves are provided on both sides of the rotating handle, and the connecting rod is positioned at the center point of the rotating groove.

[0019] Furthermore, the card slots are provided in parallel with three rows, and the buckle includes a locking block and a spring. Three buckles are provided at equal intervals on the inner sidewall of each card slot.

[0046] A high-efficiency backwash filter designed to cope with complex water quality changes has been provided for the excavation and retrieval of shallow-buried drip irrigation tape capillary tubes, and for rotary tillage of the surrounding soil. Its structural diagram is shown below. Figures 1 to 10 As shown.

[0047] An example of the present invention provides a highly efficient backwash filter structure for dealing with complex water quality changes.

[0048] It includes the main body of the recoil unit, the connecting module, and the recoil module, wherein;

[0049] like Figure 1-3 As shown,

[0050] The main body of the backflushing device includes a main pipe 1 and an extension connecting piece 11. The main pipe 1 is a high-strength plastic pipe with a minimum thickness of 3mm. Extension connecting pieces 11 are provided at both ends of the main pipe 1. The extension connecting pieces 11 are duckbill-shaped metal pieces that are easy to insert into the water inlet pipe or drip irrigation tape. Two extension connecting pieces are symmetrically provided on each side of the main pipe 1. The central angle of the extension connecting piece 11 is not less than 30°, which can achieve the connection function while saving materials and reducing costs. Its inner sidewall is fixedly connected to the inner sidewalls of the two ends of the main pipe 1. A rotating groove 12 is provided in the middle of the inner sidewall of the main pipe 1. Two rotating grooves 12 are symmetrically provided on the top and bottom and are flat-bottomed arc-shaped grooves. The structure of the flat-bottomed arc-shaped grooves can maximize the overall strength and sealing performance of the main pipe 1 while ensuring rotation space.

[0051] By setting up a backflush body 1 with a connecting module and an extension connecting piece 11, the filter can be quickly and easily installed between the water inlet pipe and the drip irrigation tape inlet. The installation and disassembly are simple, the connection is stable and reliable, and it is convenient for installation, replacement, backflushing or maintenance.

[0052] like Figure 4-10 As shown.

[0053] The connecting module includes a first fastener 2 and a second fastener 28. The first fastener 2 is symmetrically arranged at both ends of the main pipe 1 and sleeved on the outside of the extension connecting piece 11. The end of the first fastener 2 is provided with a fixing hole 21, and a fastening bolt 22 is threaded into the fixing hole 21. Two cylindrical rubber rings 23 are provided parallel to each other between the first fastener 2 and the extension connecting piece 11. The first fastener 2 is a strip-shaped metal fastener. The second fastener 28 is a strip-shaped plastic fastener. The second fastener 28 is located in the middle of the main pipe 1. A rotating handle 24 is inserted into the middle of the upper end through a connecting rod 26. Anti-slip grooves 25 are opened on both sides of the rotating handle 24. The connecting rod 24 is located at the center point of the rotating groove 12. A first strong magnet 27 is provided at the lower end of the connecting rod 26.

[0054] The upper mounting component is disposed in a rotating groove near the first strong magnetic block. A third strong magnetic block and a fourth strong magnetic block are respectively embedded in the two centrally symmetrical ends of the rotating handle. A first guide plate and a second guide plate are hinged to the inner wall of the main pipe of the backflushing body. The two guide plates are symmetrically arranged about the filter assembly and are disposed on the side of the inner wall of the main pipe of the backflushing body near the rotating handle. A fifth strong magnetic block is embedded in the suspended end of each of the two guide plates.

[0055] By setting a rotating handle 24 with a permanent magnet installed at the end and a permanent magnet located at the upper end of the backwash module, the filter screen can be flipped to achieve the backwash effect without disassembling the components. Simultaneously, the use of permanent magnets replaces the traditional through-type connecting rod, ensuring the sealing of the backwash unit and reducing the use of seals. This avoids potential leakage caused by aging or substandard seals, further conserving water resources. By setting third, fourth, and fifth magnetic blocks, during normal drip irrigation, holding the rotating handle 24 and rotating it until the third and fourth strong magnetic blocks are close to a fifth strong magnetic block and holding it there, the line connecting the third and fourth strong magnetic blocks is parallel to the fluid flow direction of the main pipe. Under the magnetic attraction of the third and fourth strong magnetic blocks to the nearby fifth magnetic block of the guide plate, the guide plate, hinged to the inner wall of the main pipe, is pressed tightly against the inner wall, ensuring... The smooth and stable water flow allows for backwashing when necessary. By holding and rotating the handle 24, the third and fourth strong magnetic blocks are moved away from the two fifth strong magnetic blocks and held in that position for a period of time. This position is then changed and held again for a period of time. By repeating this operation several times, the guide plate can be kept in a suspended and balanced position. The angle of inclination at each suspension position is different, thus guiding the flushing water flow to different flushing directions. This allows for different spraying directions on the filter assembly 5, thereby achieving the best backwashing effect. Combined with the filter screen flipping operation, the backwashing effect is greatly enhanced. During the backwashing process, water can be injected from both sides of the filter assembly. For example, after connecting to the first fastener 2 on the left side and flushing from the left side for a period of time, the first fastener 2 on that side can be disconnected, and the external water flow can be connected to the first fastener 2 on the right side, allowing the water to enter from the right side for flushing, thus achieving a thorough cleaning of the filter assembly.

[0056] The backflushing module includes an installation assembly and a filter assembly. The backflushing module is snapped into the rotating groove 12. The installation assembly includes an upper mounting part 3 and a lower mounting part 4, both of which are arc-shaped mounting parts with a groove 31 on the center side. Each groove 31 has a latch 21 on its inner wall. Three grooves are arranged in parallel. Each latch 32 includes a locking block 321 and a spring 322, achieving a good snapping effect and high strength, preventing rotation, displacement, or deformation under the impact of water flow. Three latches 32 are evenly spaced on the inner wall of each groove 31. The filter assembly includes a vertical filter screen 5, a horizontal filter screen 51, and a cross filter screen 52. The filter screen 5, horizontal filter screen 51, and cross filter screen 52 are evenly spaced, and each has a vertical sub-slot 53 and a snap-fit ​​slot 54 at both the top and bottom. The positions of the vertical sub-slots 53 and snap-fit ​​slots 54 correspond to the positions of the snap-fit ​​bolts 32. The vertical filter screen 5 and the horizontal filter screen 51 have parallel metal wires spaced no more than 2 mm apart in the middle. The cross filter screen 53 has an aperture of no less than 100 mesh. The radial direction of the metal wires in the vertical filter screen 5 is parallel to the connecting rod 26, and the radial direction of the metal wires in the horizontal filter screen 51 is perpendicular to the connecting rod 26. A second strong magnet 33 is fixedly connected to the top 3 of the upper mounting component. The upper mounting component 3 is located in the rotating groove 12 near the first strong magnet 27.

[0057] Water quality varies significantly with the seasons. In summer and autumn, due to temperature fluctuations, biological clogging caused by green algae and extracellular polymers is predominant, while in winter and spring, fine sand is the primary clogging factor. To address this, in summer and autumn, vertical and horizontal filters (5 and 51) with a wire spacing of 1-2 mm and grooves (31) with larger inner wall spacing can be used. This reduces the likelihood of clogging, decreases the frequency of backwashing, extends effective working time, and improves efficiency. Similarly, in spring and winter, vertical and horizontal filters (5 and 51) with a wire spacing of 0.5-1 mm and grooves (31) with smaller inner wall spacing can be used to improve filtration efficiency and reduce the likelihood of drip irrigation clogging.

[0058] By setting up a backwash module with three layers of filters, impurities of different particle sizes can be effectively filtered, reducing the chance of filter clogging and improving filtration effect and efficiency, thereby ensuring the reliability of drip irrigation water. The combination of vertical filter 5 and horizontal filter 51 can filter larger sand and gravel impurities, while also having a certain buffering effect to avoid damage or clogging of local filter components, thus ensuring filtration effect under long-term use conditions. The cross filter can effectively filter smaller impurities. After the specified service life, simply remove the fastening bolt 22 on the side of the first fastener 2 closest to the drip irrigation pipe, disconnect the main pipe 1 from the drip irrigation pipe, then use the handle 24 to turn the direction of the filter components 180°, and finally start the water inlet pipe to flush the filter components with a suitable water flow to wash away the impurities accumulated on the filter screen. Finally, restore the direction of all components and reinstall them to begin the next stage of use.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
