Description

Technical Field

[0001] This invention relates to the technical field of filtration equipment for agricultural irrigation, specifically a magnetized filter for agricultural irrigation. Background Technology

[0002] Given the scarcity of freshwater resources, which severely restricts the sustainable development of agriculture, the exploitation and utilization of abundant brine resources hold great promise. However, as an unconventional water resource, brine, if used directly to irrigate crops, can lead to increased soil salinity, easily inducing salt damage, deteriorating soil health, harming normal crop growth, and affecting yield and quality.

[0003] Drip irrigation is one of the most water-saving localized irrigation technologies, and it is widely used in arid and semi-arid regions of my country. The conversion of traditional flood irrigation to drip irrigation in high-standard farmland has effectively improved water use efficiency, greatly promoting water conservation and increased crop yields. However, due to the high salt content of the parent material, poor irrigation water quality, and the lack of a proper drainage system, some farmland suffers from persistent salt in the topsoil, severely impacting crop growth, development, yield, and quality. Therefore, how to scientifically and rationally utilize saline irrigation to ensure the sustainable use of water and soil resources has become a research hotspot in the field of agricultural ecology and environment. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a magnetized filter for agricultural irrigation, so as to solve the problem that water resources with high salinity cannot be directly used for irrigation.

[0005] The technical solution adopted by the present invention is: a magnetized filter for agricultural irrigation, comprising a horizontal pipe and a housing installed on the horizontal pipe, wherein a filter screen is installed inside the housing, the filter screen is cylindrical, an inlet and an outlet are respectively provided on the horizontal pipe, a partition plate is provided between the inlet and the outlet, the inlet is located on the inner side of the filter screen and the outlet is located on the outer side of the filter screen, a first magnetic element is also installed on the inner side of the filter screen, and a plurality of second magnetic elements are provided on the housing.

[0006] The above structure has the following beneficial effects:

[0007] 1. A first magnetic component and a second magnetic component are installed inside the filter screen and on the shell, respectively. The first magnetic component and the second magnetic component work together to magnetize the salt water entering the filter screen. The hydrogen bonds of water molecules in the magnetized salt water break, the molecular clusters become smaller, and the activity is enhanced. It has a stronger ability to penetrate and dissolve in the soil, which can promote the dissolution of soluble salts in the soil and the absorption of crop roots.

[0008] 2. The infiltration of magnetized saline alters the movement rate of salt ions in the soil, changing the ion flux in plant root tissues and cells. Plants regulate the absorption, transport, and distribution of ions, re-establishing ion balance mechanisms to cope with soil water and salt conditions. The increased number of free water molecules in magnetized saline allows these molecules to form more hydrogen bonds with chlorophyll a after entering plant cells, increasing the internal conversion rate of chlorophyll a. This, in turn, enhances leaf photosynthetic capacity and plant stress resistance, reduces the damage caused by salt stress, and ultimately promotes plant growth.

[0009] 3. Installing the magnetization mechanism and the filtration mechanism in the same device allows the water to be magnetized while being filtered, improving magnetization efficiency. This also reduces the overall size of the device, making it easy to install or carry and saving space. The overall magnetization and filtration device has a "T"-shaped design, which can be installed at the beginning of the drip irrigation system for easy maintenance. When buried in the ground on drip irrigation pipelines at all levels, it is beneficial for mechanized agricultural production.

[0010] Preferably, the water inlet pipe is also connected to a first magnetized pipe, which is spirally wound around the outside of the first magnetic element and located inside the filter screen.

[0011] The first magnetization pipe causes the water entering the filter to flow inside the first magnetization pipe. At the same time, the spiral pipe increases the flow time of the water in the magnetization pipe, thereby extending the effective magnetization time. After the water in the first magnetization pipe has completed one magnetization, it enters the filter and undergoes a second magnetization while being filtered, further extending the effective magnetization time and improving the magnetization effect.

[0012] Preferably, a fixing frame is provided on the outer side of the filter screen, and a spiral second magnetization groove is formed on the inner side wall of the fixing frame. The upper and lower ends of the second magnetization groove penetrate through the upper and lower end faces of the fixing frame, and the inner side wall of the fixing frame abuts against the filter screen.

[0013] The fixed frame and the spiral second magnetization groove located on the fixed frame allow water filtered by the filter screen to enter the second magnetization groove and flow along the second magnetization groove. The water flows out from the upper or lower end of the fixed frame. This arrangement can further extend the time for the water to be magnetized and improve the magnetization effect of the water.

[0014] Preferably, the horizontal pipe is further provided with a first annular protrusion, the filter screen is embedded in the inner side of the first annular protrusion, the water outlet is located on the outer side of the outer side of the first annular protrusion, and the fixing bracket abuts against the end face of the first annular protrusion.

[0015] The first annular protrusion serves two purposes: firstly, it limits the position of the filter screen, preventing it from shaking due to water flow during use; secondly, it supports the fixing frame, leaving a certain gap between the fixing frame and the outlet of the horizontal pipe, so that the magnetized water can flow smoothly out of the outlet.

[0016] Preferably, the fixing frame consists of a first half-frame and a second half-frame arranged symmetrically. The first half-frame is provided with a plurality of first pins, and the second half-frame is provided with a first insertion hole for cooperating with the first pins.

[0017] This design allows the mounting bracket to be split in half, which facilitates cleaning of the second magnetization groove on the mounting bracket and the filter screen. At the same time, the engagement between the first pin and the second socket guides the assembly of the first and second halves of the bracket and prevents relative movement between them after installation.

[0018] Preferably, the width of the first annular boss is greater than the cross-sectional diameter of the second magnetization groove, so that the first annular boss can completely cover the cross-section of the second magnetization groove. The fixing frame is also provided with several through holes, which are located outside the second magnetization groove and extend from the upper end of the fixing frame to the lower end of the fixing frame.

[0019] The first annular protrusion can fully cover the cross-section of the second magnetization tank, preventing water from flowing out from the bottom of the fixing frame. This allows all the water to flow towards the top of the fixing frame through the second magnetization tank, thus extending the flow time of the water within the fixing frame and improving the magnetization effect. At the same time, the through hole allows water flowing out from the top of the fixing frame to flow through the through hole to the bottom of the fixing frame and out from the outlet at the bottom of the fixing frame, further extending the effective magnetization time while ensuring a stable water output.

[0020] Preferably, the width of the first annular boss is smaller than the cross-sectional diameter of the second magnetizing groove, so that the second magnetizing groove is connected to the outer side of the first annular boss.

[0021] This configuration allows the bottom of the second magnetization tank to connect with the cavity outside the first annular boss, ensuring that water can only flow out from the bottom of the second magnetization tank, thus allowing the water to be fully magnetized during its flow in the second magnetization tank.

[0022] Preferably, the housing has a plurality of first grooves, and a mounting plate for fixing the second magnetic component is installed in the first groove. The mounting plate has a plurality of second grooves for engaging the second magnetic component, and a baffle for limiting the position of the second magnetic component is also installed on the mounting plate.

[0023] This design allows the mounting plate to be removed, and the second magnetic component can be added, removed, or replaced simply by removing the baffle. The optimal magnetization intensity for water retention and salt removal varies depending on the mineralization (salt content) of the irrigation brine. Similarly, the optimal magnetization intensity for yield and quality improvement varies depending on the type of crop (vegetables, fruits, grains). Therefore, by replacing the second magnetic component, the magnetization intensity can be controlled, making the magnetized irrigation water more suitable for the current irrigation water quality and the planted crops, promoting sustainable development of water, soil, and crops. Furthermore, by installing several second magnetic components in the second groove, not only can the type of magnet be changed, but the magnetic field strength and distribution can also be adjusted by increasing or decreasing the number of magnets, thus improving the adjustable range. This assembly and disassembly method is convenient and quick, effectively improving magnet replacement efficiency.

[0024] Preferably, the first groove is further provided with sliding grooves on both sides, and the mounting plate is provided with limiting plates on both sides for sliding connection with the sliding grooves.

[0025] The sliding groove design makes the installation and removal of the mounting plate simple and convenient, requiring only sliding along the groove. At the same time, the groove also limits the mounting plate installed on the housing, preventing it from moving towards the fixing frame.

[0026] Preferably, the end of the water inlet facing the horizontal pipe is a flared end, and the end of the water inlet facing the filter screen is a narrow end. The narrow end of the water inlet is also connected to a fertilizer tank.

[0027] By connecting a fertilizer tank to the inlet, fertilizer can be added to the water during the water intake process. This facilitates fertilization and also magnetizes the fertilizer, improving its dissolution efficiency. The inlet is designed with a wide opening at the bottom and a narrow opening at the top, with the fertilizer tank connected to the narrow opening. This increases the water flow velocity as the water enters the narrow opening, resulting in a decrease in fluid pressure. This creates a pressure difference between the narrow opening and the fertilizer tank. This pressure difference causes the water to adsorb the fertilizer in the fertilizer tank, automatically drawing it into the water flow and achieving automatic fertilization.

Detailed Implementation

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] Example 1

[0047] According to the instruction manual Figure 1-4 As shown, the present invention provides a magnetized filter for agricultural irrigation, including a horizontal pipe 10 and a housing 20 installed on the horizontal pipe 10. A filter screen 30 is installed inside the housing 20, wherein the filter screen 30 is cylindrical. An inlet 11 and an outlet 12 are also provided on the horizontal pipe 10. A partition plate 13 is provided on the inner side of the horizontal pipe 10 to separate the inlet 11 and the outlet 12. The inlet 11 is located on the inner side of the filter screen 30, and the outlet 12 is located on the outer side of the filter screen 30, ensuring that all water can pass through the filter screen 30 for filtration. A first magnetic element 21 is also provided on the inner side of the filter screen 30 and fixedly installed on the horizontal pipe 10. A second magnetic element 22 is installed on the housing 20.

[0048] In this embodiment, the first magnetic component 21 is a cylindrical magnetic rod, which is fixedly installed on the horizontal pipe 10 by threads. Four first grooves 23 are provided on the housing 20, and a mounting plate 24 is installed in each first groove 23. Multiple arrayed second grooves 241 are evenly provided on each mounting plate 24. The second magnetic component 22 can be embedded in the second grooves 241. At the same time, a baffle 25 for limiting the second magnetic component 22 is also bolted to the mounting plate 24. In this way, both the first magnetic component 21 and the second magnetic component 22 can be replaced, so that different strengths or numbers of the first magnetic component 21 and the second magnetic component 22 can be replaced when the mineralization of the irrigation water and the type of crop are changed, thereby achieving the best magnetization intensity and enabling the magnetized filtration device to perform at its best. Slide grooves 231 are provided on both sides of the first groove 23, and limiting plates 242 that slide with slide grooves 231 are provided on both sides of the mounting plate 24. This makes the installation of the mounting plate 24 easier and more convenient. The slide grooves 231 can also limit the mounting plate 24 and prevent the mounting plate 24 from moving in a direction other than the direction of the slide grooves 231.

[0049] In this embodiment, the end of the water inlet pipe facing the filter screen 30 is also connected to a first magnetized pipe 40, wherein the first magnetized pipe 40 is spiral and coiled around the outside of the first magnetic element 21. This arrangement allows the water entering the filter screen 30 through the water inlet 11 to first flow in the first magnetized pipe 40 and be magnetized by the first magnetic element 21 and the second magnetic element 22, which can effectively prolong the magnetization time of the brine and improve the magnetization effect. At the same time, the other end of the first magnetized pipe 40 is also located inside the filter screen 30, so that the magnetized water can still be filtered by the filter screen 30.

[0050] In this embodiment, a first annular protrusion 14 is also provided on the horizontal pipe 10. The filter screen 30 is embedded in the inner wall of the first annular protrusion 14. The first annular protrusion 14 can limit the lower end of the filter screen 30 to prevent the filter screen 30 from shaking under the impact of water flow. At the same time, a second annular protrusion 31 is also provided at the upper end of the filter screen 30. The second annular protrusion 31 can be embedded in the top of the first magnetic component 21, thereby limiting the upper end of the first magnetic component 21 and the filter screen 30. A third annular protrusion 15 is also provided on the horizontal pipe 10. The inner wall of the third annular protrusion 15 is provided with an internal thread, and the housing 20 is provided with an external thread that cooperates with the internal thread, so that the housing 20 can be connected to the horizontal pipe 10 by the thread. At the same time, the inner wall of the top of the housing 20 abuts against the top of the filter screen 30, which can further limit the filter screen 30 and prevent the filter screen 30 from shaking.

[0051] Its working principle is as follows: the two ends of the horizontal pipe 10 are connected to the water inlet pipe. Under the action of the partition plate 13, the water flows into the first magnetized pipe 40 from the inlet 11 and flows around the first magnetic element 21. During the water flow, the first magnetic element 21 and the second magnetic element 22 respectively magnetize the water flow on both sides of the first magnetized pipe 40, causing the hydrogen bonds of water molecules in the salt water to break, the molecular clusters to become smaller, and the activity to be enhanced. It has a stronger penetration and dissolution capacity in the soil, which can promote the dissolution of soluble salts in the soil and the absorption of crop roots. The water flow after the first magnetization flows out from the first magnetized pipe 40 and enters the inner side of the filter screen 30. Under the filtering effect of the filter screen 30, impurities in the water flow are blocked inside the filter screen 30. During the filtration process, the water can continue to be magnetized, further improving the activity of the salt water. The filtered water flows back into the horizontal pipe 10 from the outlet 12 on the outside of the filter screen 30, and can then be used for irrigation of farmland.

[0052] Meanwhile, when irrigating different types or regions of farmland, the magnetization intensity needs to be adjusted according to the different crop types or the different mineralization of local irrigation water. Rotating the housing 20 allows it to be removed from the third annular boss 15. Then, by pulling out the mounting plate 24 in the housing 20, the second magnetic component 22 can be replaced or the number of the second magnetic components 22 can be adjusted, thereby adjusting the magnetization intensity. This allows the magnetized filter to be applied to different regions or different types of crops without replacing the entire device, reducing the user's operating costs.

[0053] Example 2

[0054] According to the instruction manual Figure 5-10 As shown, the difference between this embodiment and embodiment 1 is that a fixing frame 50 is also installed on the outside of the filter screen 30. A spiral second magnetization groove 53 is opened on the inner side wall of the fixing frame 50. The upper and lower ends of the second magnetization groove 53 penetrate through the upper and lower end faces of the fixing frame 50. The inner wall diameter of the fixing frame 50 is the same as the outer wall diameter of the filter screen 30, and the inner wall of the fixing frame 50 abuts against the outer wall of the filter screen 30. The bottom end of the fixing frame 50 abuts against the upper end face of the first annular boss 14.

[0055] In this embodiment, the fixing frame 50 consists of a first half-frame 51 and a second half-frame 52 arranged symmetrically. Three first pins 511 are fixedly connected to one side of the first half-frame 51, and a first insertion hole 521 for cooperating with the first pins 511 is provided on the second half-frame 52. In order to improve the installation stability of the first half-frame 51 and the second half-frame 52, three second pins 522 are fixedly connected to one side of the second half-frame 52, and a second insertion hole for cooperating with the second pins 522 is provided on the first half-frame 51.

[0056] In this embodiment, the width of the first annular boss 14 is greater than the cross-sectional diameter of the second magnetization groove 53, so that the first annular boss 14 can completely cover the end face of the second magnetization groove 53. A limiting boss 55 is provided on the top of the housing 20, so that the fixing frame 50 and the top surface of the housing 20 have an overflow cavity 56. At the same time, eight through holes 54 are provided on the fixing frame 50 from top to bottom, and the through holes 54 are all located on the outside of the second magnetization groove 53.

[0057] In this embodiment, the first magnetization pipe 40 is a double helical pipe, that is, the pipe is composed of two sets of helical pipes connected at the upper end, so that the water inlet 41 and the water outlet 42 of the first magnetization pipe 40 are both located at the lower end. This arrangement allows the water that has been magnetized for the first time to flow out from the bottom, so that most of the water can move from the bottom end of the second magnetization tank 53 to the top end, so that the water can be fully magnetized.

[0058] The working principle of this embodiment is as follows: after the brine passes through the filter screen 30, it enters the second magnetization tank 53 in the fixed frame 50. Since the bottom of the second magnetization tank 53 is blocked by the first annular boss 14, the water in the second magnetization tank 53 can only flow upward and enter the overflow chamber 56. Then, it flows through the through hole 54 through the fixed frame 50 to the bottom of the fixed frame 50, and then flows out from the outlet 12. During the flow in the second magnetization tank 53 and through hole 54, it can be magnetized by the first magnetic element 21 and the second magnetic element 22, which further prolongs the effective magnetization time and improves the magnetization effect.

[0059] When the filter screen 30 needs to be cleaned, the first half-frame 51 and the second half-frame 52, which are inserted into each other, are pulled toward the sides of the filter screen 30 to separate the first half-frame 51 and the second half-frame 52, so that the filter screen 30 can be taken out for cleaning. At the same time, the second magnetization groove 53 on the inside of the fixing frame 50 can also be cleaned to prevent impurities from adhering to the filter screen 30 and making it difficult to separate the fixing frame 50 from the filter screen 30. After cleaning, the first half-frame 51 and the second half-frame 52 are fastened to the outside of the filter screen 30 to complete the installation, which also reduces the installation difficulty of the fixing frame 50.

[0060] Example 3

[0061] According to the instruction manual Figure 11-14As shown, the difference between this embodiment and embodiment 1 is that a fixing frame 50 is also installed on the outside of the filter screen 30. A spiral second magnetization groove 53 is opened on the inner side wall of the fixing frame 50. The upper and lower ends of the second magnetization groove 53 penetrate through the upper and lower end faces of the fixing frame 50. The inner wall diameter of the fixing frame 50 is the same as the outer wall diameter of the filter screen 30, and the inner wall of the fixing frame 50 abuts against the outer wall of the filter screen 30. The bottom end of the fixing frame 50 abuts against the upper end face of the first annular boss 14.

[0062] In this embodiment, the top of the fixing frame 50 abuts against the top of the housing 20, and the width of the first annular boss 14 is smaller than the cross-sectional diameter of the second magnetization groove 53, so that the bottom end of the second magnetization groove 53 can be connected to the cavity outside the first annular boss 14, so that water can only flow out from the bottom of the second magnetization groove 53.

[0063] In this embodiment, the first magnetized pipe 40 is a single spiral pipe, that is, the water inlet end 41 of the pipe is located at the lower end, and the water outlet end 42 of the pipe is located at the upper end of the pipe, so that the water can flow out from the upper end of the pipe. With this arrangement, the water that has been magnetized for the first time flows out from the upper end, so that most of the water can flow from the upper end of the second magnetized tank 53 to the lower end, so that the water can be fully magnetized.

[0064] The working principle of this embodiment is that after the brine passes through the filter screen 30, it flows into the second magnetization tank 53 in the fixed frame 50. The water flows along the bottom of the second magnetization tank 53 to the outlet 12. During the flow in the second magnetization tank 53, it can be magnetized by the first magnetic element 21 and the second magnetic element 22, which further prolongs the effective magnetization time and improves the magnetization effect.

[0065] Example 4

[0066] According to the instruction manual Figure 15 As shown, the difference between this embodiment and embodiment 1 is that the side of the water inlet 11 facing the horizontal pipe 10 is a flared end, while the side of the water inlet 11 facing the filter screen 30 is a narrow end. A fertilizer pipe 61 is connected to the narrow end, and a fertilizer tank 60 is connected to the other end of the fertilizer pipe 61. In this embodiment, the fertilizer tank 60 is connected to the horizontal pipe 10 by a thread.

[0067] A water pressure sensor 71 for monitoring water pressure is connected to the horizontal pipe 10. A display screen for displaying monitoring data is also installed on the top of the housing 20. A monitoring hole 72 is also provided on the horizontal pipe 10. The monitoring hole 72 is used to insert a high-precision gaussmeter to monitor the magnetization intensity of the treated water. The monitoring hole is normally closed with a threaded plug. The plug can be removed and the probe of the gaussmeter can be inserted only when a spot check is required.

[0068] The working principle of this embodiment is as follows: when water flows into the first magnetized pipe 40 from the inlet 11, the flow velocity increases as the water enters the narrow end. This increased velocity is accompanied by a decrease in fluid pressure, creating a pressure difference between the narrow end and the fertilizer tank 60. This pressure difference causes the water to adsorb the fertilizer in the fertilizer tank 60, thus automatically drawing the fertilizer into the water flow, achieving automatic fertilization. Simultaneously, the water pressure sensor 71 monitors the water pressure at the outlet. When the filter screen becomes clogged to varying degrees, the water pressure increases. When the water pressure reaches a certain specified value, it alerts the user to disassemble and clean the filter. At the same time, the gaussmeter monitors the magnetization effect. When encountering unforeseen circumstances or natural demagnetization of the magnet, the magnetization intensity of the water decreases, prompting the user to replace the magnet.

[0069] Example 5

[0070] According to the instruction manual Figure 16 As shown, the difference between this embodiment and embodiment 1 is that a heat insulation layer 81 is also installed on the outside of the housing 20. In this embodiment, the heat insulation layer 81 is a double-sided aluminum pearl cotton heat insulation film. The heat insulation layer protects the housing 20 and can prevent the first magnetic component and the second magnetic component inside the housing 20 from being demagnetized under high temperature.

[0072] The preferred embodiments of the present invention have been described above, but should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of the present invention are within the scope of protection of the present invention.
