Technical Field

[0001] The present invention relates to the field of environmental water treatment, and particularly to an hourglass-shaped floating piezoelectric net cone filter dual-effect water purification device. Background Art

[0002] With the increasing severity of global water resource pollution, people's requirements for water safety and quality are getting higher and higher. Traditional water purification devices use reverse osmosis membranes to filter water. The working principle of the reverse osmosis membrane is mainly to use pressure as the driving force. Through the characteristics of the semi-permeable membrane, water molecules and other small molecules and ions can pass through, while macromolecular substances are blocked, so as to achieve the purpose of purifying water.

[0003] The operation of a reverse osmosis water purifier requires a certain water pressure, and additional pressure equipment is needed to pressurize the water to penetrate the reverse osmosis membrane. However, for small water purifiers, the pressure equipment will increase the manufacturing cost, and the pressure equipment usually needs to be driven by electricity, consuming a large amount of energy. Summary of the Invention

[0004] The purpose of the present invention is to overcome the existing defects and provide an hourglass-shaped floating piezoelectric net cone filter dual-effect water purification device, which does not require an external power supply, can apply pressure to the water during filtration, making the device convenient and efficient and reducing energy consumption, thus saving the manufacturing cost.

[0005] The technical solution to achieve the above purpose is: an hourglass-shaped floating piezoelectric net cone filter dual-effect water purification device, including a columnar water inlet bucket. The upper surface of the columnar water inlet bucket is provided with a first water inlet hole, and a water inlet pipe is arranged in the first water inlet hole. The lower surface of the columnar water inlet bucket is provided with a water outlet. Two sliding grooves are arranged on the inner wall of the columnar water inlet bucket, and a floating plate is slidably connected in each sliding groove. The floating plate is located directly below the first water inlet hole. The lower end of the columnar water inlet bucket is threadedly connected with an annular outer shell, and a filtering component for purifying water quality is installed in the annular outer shell. The lower end of the annular outer shell is detachably connected in a water storage seat.

[0006] Preferably, the filtering component includes an hourglass-shaped support structure, a plurality of needle cone-shaped filter nozzles, a piezoelectric hollow fiber filter membrane, an upper partition board, a lower partition board and a water outlet pipe. The inner wall of the annular outer shell is respectively connected with the upper partition board and the lower partition board. The inner wall of the annular outer shell is installed with the hourglass-shaped support structure. The upper and lower end faces of the hourglass-shaped support structure are respectively in close contact with the upper partition board and the lower partition board. The inner wall of the hourglass-shaped support structure is connected with the piezoelectric hollow fiber filter membrane. The upper and lower sides of the piezoelectric hollow fiber filter membrane are in close contact with the inner side wall of the annular outer shell. A plurality of needle cone-shaped filter nozzles are arranged on the outer side wall of the piezoelectric hollow fiber filter membrane. The water outlet pipe is arranged on the outer side wall of the annular outer shell. The bottom of the columnar water inlet bucket is in close contact with the upper partition board.

[0007] Preferably, the piezoelectric hollow fiber filter membrane divides the interior of the annular housing into two regions, namely a filtration region and a purified water region, and the purified water region is communicated with the water outlet pipe.

[0008] Preferably, a second water inlet hole is formed in the upper partition plate, and a sewage discharge hole is provided on the lower partition plate.

[0009] Preferably, an annular support plate is provided on the inner wall of the water storage base, and the annular support plate is in contact with the lower partition plate.

[0010] Preferably, a sealing gasket is connected to the inner wall of the water storage base, and the sealing gasket is also connected to the annular support plate, and the sealing gasket is closely attached to the outer wall of the annular housing.

[0011] Preferably, the production materials of the plurality of needle cone-shaped filter tips and the piezoelectric hollow fiber filter membrane are the same.

[0012] The beneficial effects of the present invention are as follows: After the water in the columnar water inlet bucket and the filtration region accumulates to a certain amount, the floating plate is affected by the buoyancy of the water and blocks the first water inlet hole. At this time, the water in the water inlet pipe will exert a downward pressure on the floating plate, and the incoming water replenishes the decreasing water level of the ejected water flow. The floating plate blocks the first water inlet hole again and generates pressure on the lower part again. This continuous process causes continuous pressure to be generated inside the columnar water inlet bucket and the filtration region. Through this structure, pressure can be applied to the water being filtered, so that the water can be squeezed through the piezoelectric hollow fiber filter membrane for filtration. In this way, no external power supply is required, pressure can be applied to the water being filtered, making the device convenient, efficient, reducing energy consumption, and saving manufacturing costs.

[0019] Specifically, the filtering component includes an hourglass-shaped support structure 5, multiple needle cone-shaped filter nozzles 6, a piezoelectric hollow fiber filter membrane 7, an upper partition plate 11, a lower partition plate 12, and a water outlet pipe 15. The inner walls of the annular outer shell 8 are respectively connected to the upper partition plate 11 and the lower partition plate 12. The hourglass-shaped support structure 5 is installed on the inner wall of the annular outer shell 8. The upper and lower end faces of the hourglass-shaped support structure 5 are respectively in close contact with the upper partition plate 11 and the lower partition plate 12. The inner wall of the hourglass-shaped support structure 5 is connected to the piezoelectric hollow fiber filter membrane 7. The upper and lower sides of the piezoelectric hollow fiber filter membrane 7 are in close contact with the inner side wall of the annular outer shell 8. The outer side wall of the piezoelectric hollow fiber filter membrane 7 is provided with multiple needle cone-shaped filter nozzles 6. The angle of the apex of the needle cone-shaped filter nozzle 6 is 20°, the aspect ratio (longest diameter) of the needle cone-shaped filter nozzle 6 is 3, and the ratio of the longest diameter to the shortest diameter of the needle cone-shaped filter nozzle 6 is 4, so that the water flow can generate a jet under pressure, improving the rate of purified water.

[0020] Specifically, a water outlet pipe 15 is provided on the outer side wall of the annular outer shell 8. The bottom of the cylindrical water inlet bucket 2 is in close contact with the upper partition plate 11; the piezoelectric hollow fiber filter membrane 7 divides the interior of the annular outer shell 8 into two regions, namely a filtering region 13 and a purified water region 14. The purified water region 14 is communicated with the water outlet pipe 15; a second water inlet hole 16 is opened on the upper partition plate 11, and a sewage discharge hole 19 is provided on the lower partition plate 12; an annular support plate 18 is provided on the inner wall of the water storage base 10, and the annular support plate 18 is in contact with the lower partition plate 12; a sealing gasket 20 is connected to the inner wall of the water storage base 10.

[0021] Specifically, the materials for making the multiple needle cone-shaped filter nozzles 6 and the piezoelectric hollow fiber filter membrane 7 are the same, and the materials are selected as follows: PVDF-HFP (polyvinylidene fluoride-hexafluoropropylene) is used as the main piezoelectric material, and its piezoelectric performance enables the filter membrane to generate voltage when subjected to water flow pressure, thereby achieving a self-cleaning effect; PMMA (polymethyl methacrylate) is used as an auxiliary material, which can improve the structural stability and mechanical properties of the filter membrane, and at the same time helps to control the morphology and pore size of the fibers; PVP (polyvinylpyrrolidone) is used as a carrier material, which acts as a pore-forming agent in the electrospinning process, helping to form a filter membrane structure with specific pore sizes; FeCl3·6H2O is used as an inorganic reinforcing substance doped with PVDF to improve the piezoelectric performance of the composite fiber membrane; ethanol is used to dissolve the above materials to form an electrospinning solution; The manufacturing steps are as follows: Weigh PVDF-HFP, PMMA, FeCl3·6H2O, and PVP, add them to an appropriate amount of organic solvent, and stir with a magnetic stirrer at room temperature for 24 hours until completely dissolved to form a homogeneous spinning solution.

Heat-treat the fiber membrane obtained by electrospinning to remove residual solvents and solidify the fiber structure; perform polarization treatment on the heat-treated fiber membrane to enhance piezoelectric properties.

[0022] Working principle: The water to be filtered enters the cylindrical water inlet bucket 2, the filtration area 13, and the water storage base 10 through the water inlet pipe 1. After the water in the cylindrical water inlet bucket 2, the filtration area 13, and the water storage base 10 accumulates to a certain amount, the floating plate 3 is affected by the buoyancy of the water and blocks the first water inlet hole 9. At this time, the water in the water inlet pipe 1 will exert a downward pressure on the floating plate 3, and the incoming water replenishes the decreasing water level of the ejected water flow. The floating plate 3 blocks the first water inlet hole 9 again and generates pressure downward again. This continuous process causes continuous pressure to be generated inside the cylindrical water inlet bucket 2, the filtration area 13, and the water storage base 10, which can squeeze the water to pass through the piezoelectric hollow fiber filter membrane 7 for filtration, and then the purified water is discharged into the purified water area 14 through multiple needle cone-shaped filter nozzles 6, and the purified water is then discharged through the water outlet pipe 15; The piezoelectric hollow fiber filter membrane 7 utilizes its characteristic of generating electricity by its own water pressure to generate active oxygen for sterilization while filtering tiny substances in the water, and the piezoelectric effect can decompose impurities to achieve self-cleaning, preventing the piezoelectric hollow fiber filter membrane 7 from being blocked. The impurities fall off from the piezoelectric hollow fiber filter membrane 7 and pass through the sewage discharge hole 19 to deposit on the inner bottom surface of the water storage base 10; In order to prevent excessive accumulation of impurities inside this device from affecting the water purification work, after this device has been used for a certain period of time, pull out the annular outer shell 8 from the water storage base 10, pour out the impurities deposited on the inner bottom surface of the water storage base 10, clean them, and then reassemble this device.
