Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment technology, specifically to a fertilizer and water treatment irrigation device with centrifugal filtration function. Background Technology

[0002] In modern large-scale agricultural production, integrated water and fertilizer irrigation technology has become a core technology for farmland irrigation and fruit and vegetable cultivation due to its advantages in water and fertilizer conservation and improved crop growth. Fertilizer and water treatment irrigation devices, as the core equipment of integrated water and fertilizer systems, are mainly used to filter and purify wastewater from mixed fertilizers and recycled fertilizer water from the field, removing particulate matter such as silt, fertilizer residue, and suspended impurities from the water. This prevents impurities from clogging irrigation pipes and drip irrigation nozzles, ensuring continuous and stable irrigation operations. Currently, most mainstream fertilizer and water treatment irrigation devices on the market adopt a dual filtration structure combining centrifugal filtration and fine filtration through filter tubes. Centrifugal force is used to quickly separate large particles of impurities, and then the built-in filter tubes complete the fine filtration of the water, effectively improving the purification effect of fertilizer and water and adapting to various complex field fertilizer and water conditions.

[0003] However, existing fertilizer and water treatment irrigation devices with centrifugal filtration functions still have many structural defects in actual field applications, which seriously restrict the irrigation efficiency and operational stability of the devices. Firstly, the filter tubes and filter holes of existing devices are prone to clogging. Field fertilizer and water have a complex composition, containing not only inorganic impurities such as silt and soil particles, but also undissolved fertilizer clumps and suspended organic matter. These impurities are easily adsorbed and accumulated inside the filter holes and on the outer wall of the filter tubes during the filtration process. As the operating time increases, the degree of clogging of the filter holes continues to worsen, directly leading to a significant decrease in fertilizer and water filtration flux and a surge in water flow resistance. This not only reduces the fertilizer and water filtration and purification efficiency, causing poor irrigation water supply, but also increases the water delivery load on the equipment, which can easily lead to problems such as pipeline pressurization and water pump overload during long-term operation.

[0004] Secondly, existing filter cartridges lack dedicated positioning and fixing mechanisms for the filter tubes. Traditional devices simply place and embed the filter tubes inside the filter cartridge without providing corresponding limiting, positioning, or fixing structures. Under the continuous impact of water flow, the filter tubes are prone to radial displacement, axial swaying, or even slight misalignment within the filter cartridge. After the filter tubes become misaligned, a continuous gap forms between their outer wall and the inner wall of the filter cartridge. Raw fertilizer water that has not been finely filtered by the filter tubes can directly flow out through this gap, bypassing the filtration area of ​​the filter tubes. This results in incomplete filtration of the fertilizer water, and a large amount of impurities enter subsequent irrigation pipes and farmland soil with the irrigation water. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] refer to Figures 1-8 The illustrated fertilizer and water treatment irrigation device with centrifugal filtration function includes a base plate 1, a filter cylinder 10, and an output pipe 14. A filter tube 19 is installed inside the filter cylinder 10 via a limiting component. The limiting component is used to fix the filter tube 19 and seal the installation gap. A cleaning component is provided inside the filter cylinder 10. A specific embodiment is shown below: Example

[0022] A mixing drum 3 and a stainless steel tank 2 are fixedly installed on the upper surface of the base plate 1. A feeding pipe 6 is provided on the top of the mixing drum 3. A protective cover 7 is threadedly connected to the outer wall of the feeding pipe 6. Two cyclone separators 15 are fixedly connected to the outer wall of the stainless steel tank 2 and are connected to the stainless steel tank 2. A conveying pipe 4 is fixedly connected to the output end of the cyclone separator 15. A control box 5 is fixedly connected to the outer wall of one of the cyclone separators 15. A valve body 8 is fixedly connected to the output end of the conveying pipe 4. A connecting pipe 47 is fixedly connected to the end of the valve body 8 away from the conveying pipe 4. The end of the connecting pipe 47 away from the valve body 8 is fixedly connected to the separation pipe 16. A booster pump 11 is fixedly connected to the outer wall of the stainless steel tank 2. Two second drain valves 12 are fixedly connected to the stainless steel tank 2. An end cap 17 is embedded in the upper end of the filter cylinder 10. A clamp 18 is fitted on the outer wall of the end cap 17. The output pipe 14 is connected to the filter cylinder 10. A first drain valve 9 is fixedly connected to the filter cylinder 10.

[0023] Fertilizer, water, and other raw materials are fed into the mixing drum 3 through the feeding pipe 6. The mixing drum 3 is equipped with a stirring paddle to stir the raw materials, completing the fertilizer-water mixing process. During the mixing and settling process, tightening the protective cover 7 can seal the opening of the feeding pipe 6, effectively preventing external dust and debris from entering the mixing drum 3. The fertilizer-water mixture flows into the cyclone separator 15 through the input pipe 13. The fertilizer-water mixture rotates at high speed in the cyclone separator 15, forming a strong swirling field. Impurities such as sand and iron filings with a density greater than that of the fertilizer-water mixture are thrown towards the inner wall of the cyclone separator 15 and settle downwards along the inner wall of the cyclone separator 15, falling into the stainless steel tank 2 at the bottom. The cyclone separator 15 can perform centrifugal separation of the initially mixed fertilizer-water mixture, quickly screening out large particles and undissolved impurities inside the fertilizer-water mixture. The fertilizer clumps, achieving initial centrifugal removal of impurities from the fertilizer solution. The second drain valve 12 can be opened periodically to discharge large particles of impurities and sludge residue that have settled inside the stainless steel tank 2, preventing impurities from accumulating and affecting equipment operation. The operator can adjust the opening of the valve body 8 according to the irrigation needs to precisely control the fertilizer solution delivery rate. With the help of the booster pump 11, the fertilizer solution is sent into the filter cylinder 10 through the delivery pipe 4, valve body 8, connecting pipe 47, and separation pipe 16. At the same time, the end cap 17 and clamp 18 ensure the sealing performance of the filter cylinder 10. The clean fertilizer solution after fine filtration by the filter cylinder 10 is delivered to the outside through the output pipe 14 to complete the irrigation operation. The first drain valve 9 is used to discharge the fine impurities and sewage trapped inside the filter cylinder 10 to ensure the cleanliness of the inside of the filter cylinder 10. Example

[0024] The limiting assembly includes a hinge seat 43 and a pressure plate 37. A limiting cavity 34 is circumferentially formed on the bottom wall of the filter cylinder 10. Multiple inclined grooves 38 are evenly formed in the limiting cavity 34. Slide seats 39 are slidably connected in the inclined grooves 38. A sealing ring 30 is fixedly connected to the upper end of the multiple slide seats 39. A guide groove 41 and a V-shaped groove 46 are circumferentially formed on the bottom wall of the limiting cavity 34. A return spring 44 is installed in the V-shaped groove 46. One end of the return spring 44 is fixedly connected to the bottom wall of the V-shaped groove 46, and the other end of the return spring 44 is fixed to the pressure plate 37. 7. Fixed connection: The two ends of the pressure plate 37 are rotatably connected to the hinge plate 45. The end of the hinge plate 45 away from the pressure plate 37 is rotatably connected to the hinge seat 43, and the hinge seat 43 is slidably connected to the guide groove 41. The end of the hinge seat 43 near the filter tube 19 is fixedly connected to the clamping plate 42, and the clamping plate 42 abuts against the filter tube 19. The upper end of the hinge seat 43 is fixedly connected to the pressing rod 40, and the pressing rod 40 abuts against the slide seat 39. The sealing ring 30 is self-adaptive pressing and positioning is achieved by sliding the pressing rod 40 through the hinge seat 43.

[0025] When the filter tube 19 is inserted into the limiting cavity 34, the filter tube 19 is subjected to downward pressure, which causes the filter tube 19 to move downward as a whole. The bottom of the filter tube 19 presses down and abuts against the pressure plate 37, forcing the pressure plate 37 to move downward. During the downward pressing process, the hinge plates 45 at both ends of the pressure plate 37 rotate and deflect. Using the lever hinge transmission principle, the hinge seats 43 on both sides are pulled to slide horizontally along the guide groove 41 toward the center of the filter tube 19. This causes the arc-shaped clamping plates 42 at the ends of the hinge seats 43 to move inward synchronously, automatically clamping and adhering to the outer wall of the filter tube 19, realizing the automatic centering and firm clamping of the filter tube 19, effectively resisting the shaking and displacement caused by the impact of high-pressure water flow. While the hinge seat 43 slides inward, the pressing rod 40 at the top of the hinge seat 43 moves synchronously and pushes the slide 39 upward along the inclined groove 38, pressing the sealing ring 30 at the top of the slide 39, so that the sealing ring 30 adaptively presses the bottom of the filter tube 19, sealing the gap between the filter tube 19 and the limiting cavity 34, preventing untreated fertilizer water from entering the limiting cavity 34. After the filter tube 19 is installed, the end cap 17 is installed with the filter cylinder 10, and the end cap 17 is clamped and limited with the filter cylinder 10 by the clamp 18, improving the sealing of the filter cylinder 10 during the filtration process. Example

[0026] A separation tube 16 is fixedly connected to the outer wall of the filter cylinder 10, and the separation tube 16 is connected to the filter cylinder 10. A fixing plate 26 is fixedly connected inside the separation tube 16. A drive shaft 27 is rotatably connected to one end of the fixing plate 26 near the filter cylinder 10. Multiple blades 28 are evenly fixedly connected to the outer wall of the drive shaft 27. A first bevel gear 35 is fixedly connected to one end of the drive shaft 27 away from the fixing plate 26. A shaft 20 is rotatably connected inside the filter cylinder 10. A second bevel gear 36 is fixedly connected to one end of the shaft 20 near the drive shaft 27. The teeth of the first bevel gear 35 and the second bevel gear 36 mesh. A spur gear 29 is fixedly connected to the other end of the shaft 20. The wheel 29 meshes with the teeth of the toothed ring 21. The cleaning assembly includes the toothed ring 21 and the reciprocating screw 23. The toothed ring 21 and the reciprocating screw 23 are rotatably connected inside the filter cylinder 10. Multiple brush plates 25 are fixedly connected to the toothed ring 21 around its circumference. The bristles of the brush plates 25 abut against the filter tube 19. A slide rail 22 is fixedly connected to the inner wall of the filter cylinder 10. A slider 31 is slidably connected inside the slide rail 22. A guide box 32 is slidably connected to the outer wall of the reciprocating screw 23. The guide box 32 is fixedly connected to the slider 31. A guide block 33 is rotatably connected inside the guide box 32. Arc-shaped scrapers 24 are fixedly connected to both ends of the guide box 32. The arc-shaped scrapers 24 abut against the inner wall of the filter cylinder 10.

[0027] When the ferrous water flows at high speed through the separator 16, it impacts the blades 28, causing them to rotate. This rotation in turn drives the drive shaft 27 to rotate synchronously. The drive shaft 27 then drives the first bevel gear 35 to rotate. Since the teeth of the first bevel gear 35 and the second bevel gear 36 mesh, the first bevel gear 35 drives the shaft 20 to rotate. When the shaft 20 rotates, it drives the toothed ring 21 to rotate around the outside of the filter tube 19 via the spur gear 29. The toothed ring 21 is fitted onto the outside of the filter tube 19 and does not affect the normal filtration operation of the ferrous water. When the toothed ring 21 rotates around the filter tube 19... During operation, all brush plates 25 can be driven to synchronously sweep around the filter tube 19, thoroughly removing fertilizer residue and sludge particles attached to the outer wall of the filter tube 19, clearing the filter holes and preventing the filter holes of the filter tube 19 from becoming clogged. Since the toothed ring 21 meshes with the teeth of the spur gear 29 installed at the lower end of the reciprocating screw 23, the rotation of the toothed ring 21 will synchronously drive the reciprocating screw 23 to rotate. The slider 31 can slide vertically back and forth along the slide rail 22. Through the limiting cooperation between the slider 31 and the slide rail 22, the vertical movement of the guide box 32 is ensured to be stable and there will be no rotational deviation. The guide block 33 matches the thread groove of the reciprocating screw 23. Relying on the thread trajectory of the reciprocating screw 23, it precisely drives the guide box 32 to achieve uniform reciprocating lifting and lowering. During the reciprocating movement of the guide box 32, the arc scraper 24 can continuously scrape away the stubborn dirt and viscous fertilizer deposits attached to the inner wall of the filter cylinder 10, avoiding the long-term accumulation and solidification of impurities. Moreover, the arc scraper 24 does not contact the shaft 20 during the movement, so it will not affect the normal rotation of the shaft 20.

[0028] The working principle of this invention is as follows: During operation, the operator feeds fertilizer, water and other proportioned raw materials into the mixing drum 3 through the feeding pipe 6 at the top of the mixing drum 3. The raw materials are fully stirred by the mixing paddle inside the mixing drum 3 to complete the fertilizer-water proportioning operation. The proportioned fertilizer-water is transported through the input pipe 13 to the two cyclone separators 15 on the outer wall of the stainless steel tank 2. The cyclone separators 15 are connected to the stainless steel tank 2. Impurities and sludge residue will settle and accumulate inside the stainless steel tank 2. After being pressurized, the fertilizer-water passes through the conveying pipe 4, valve body 8 and connecting pipe 47 at the output end of the cyclone separator 15 in sequence, and finally enters the filter cylinder 10 through the separation pipe 16. Then, the filter tube 19 completes the secondary fine filtration. The purified fertilizer-water is transported out through the output pipe 14. Fine dirt and sewage trapped inside the filter cartridge 10 can be discharged periodically through the first drain valve 9. The filter tube 19 presses down on the pressure plate 37, causing the pressure plate 37 to move downward and drive the hinge plates 45 at both ends to rotate and deflect, pulling the hinge seats 43 on both sides to slide towards the center along the guide groove 41, causing the end clamping plate 42 to tighten inward and automatically clamp and fix the filter tube 19. At the same time, the hinge seat 43 drives the extrusion rod 40 to push the slide 39 upward along the inclined groove 38, extruding the sealing ring 30 to adaptively press the bottom of the filter tube 19 and seal the installation gap of the limiting cavity 34. The high-speed flow of ferrous water through the separation pipe 16 impacts the impeller 28, driving the drive shaft 27 to rotate. Through the meshing of the first bevel gear 35 and the second bevel gear 36, the shaft 20 rotates. The shaft 20 drives the gear ring 21 to rotate around the filter tube 19 through the spur gear 29, causing the brush plate 25 to continuously scrub the outer wall of the filter tube 19. At the same time, the gear ring 21 drives the reciprocating screw 23 to rotate. Under the limiting guidance of the slide rail 22 and the slider 31, and with the trajectory constraint of the guide block 33, the guide box 32 is driven to make a smooth vertical reciprocating lifting and lowering motion. The arc-shaped scrapers 24 at both ends of the guide box 32 continuously scrape off the viscous sediment and stubborn dirt attached to the inner wall of the filter cylinder 10.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
