[0001] This invention relates to the field of water treatment technology, specifically an ultrasonic vibration filter self-cleaning water purifier, and more particularly to a water purification device that uses a stainless steel mesh filter for water purification and automatically cleans the stainless steel mesh filter element through ultrasonic vibration. This device is mainly for filtering water with a high content of impurities. Background Technology
[0002] Mountainous areas often rely on gravity-fed water supply from elevated reservoirs. These reservoirs contain various impurities such as silt, iron, manganese, algal toxins, and seasonal humus. Especially during the rainy season, the water turbidity is extremely high, which can easily clog the pre-filter and affect the water safety of mountain villagers.
[0003] Ordinary pre-filters, when used to purify water with high impurity content, suffer from rapid filter clogging, long replacement times, and are prone to unstable water pressure and water outages. There is an urgent need to invent a water purifier for filtering and purifying tap water in mountainous areas that can automatically clean the filter cartridge. Summary of the Invention
[0004] An ultrasonic vibration filter self-cleaning water purifier, specifically a water purification device that uses a stainless steel mesh filter for water purification and automatically cleans the stainless steel mesh filter element through ultrasonic vibration, is mainly designed for filtering water with high impurity content. It primarily consists of three functional components: a frame assembly, a water purification tank system, and an ultrasonic vibration system. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown.
[0005] The frame assembly consists of four central crossbeams welded and installed at the middle position of four supporting columns, with central support plates welded to the four central crossbeams. Four upper crossbeams are welded and installed on the upper crossbeams, with an upper platform welded and installed on the upper crossbeams. A limit cylinder is welded and installed around the right-side circular hole of the upper platform. Figure 6 As shown.
[0006] The described water purification tank system has a top annular flange welded to the top of the tank body and a bottom annular flange welded to the bottom of the tank body. A bottom drain threaded pipe is welded and installed at the central circular hole at the bottom of the tank body. The inlet and outlet of the bottom drain solenoid valve are respectively connected to the bottom drain threaded pipe and the wastewater discharge pipe. A tank inlet threaded pipe is welded to the opening on the side of the tank body. The inlet and outlet of the inlet solenoid valve are respectively connected to the inlet pipe and the tank inlet threaded pipe. A sealing disc flange is welded to the bottom edge of the outer circular surface of the basin-shaped tank cover, and the top of the basin-shaped tank cover has an opening. A top-outlet threaded pipe is welded and installed, and a clean water outlet pipe is connected to the top-outlet threaded pipe; several round holes are opened on the circular filter element mounting plate, and the threaded pipe opening at the top of the stainless steel mesh filter element is inserted into the round holes installed on the circular filter element mounting plate and fastened by the filter element fastening nut; a sealing ring, a circular filter element mounting plate, a sealing ring, and a tank cover sealing disc flange are stacked from bottom to top on the circular flange at the top of the tank and fastened by several sets of bolt assemblies B; several stainless steel mesh filter elements installed on the circular filter element mounting plate are located in the inner cavity of the water purification tank, such as Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 As shown.
[0007] The ultrasonic vibration system consists of an ultrasonic generator mounted on a central support plate of the frame assembly, and several ultrasonic transducers securely installed at the bottom of the water purification tank. The ultrasonic generator and the ultrasonic transducers are connected via drive cables to form an ultrasonic drive connection. Figure 2 , Figure 4 , Figure 5 , Figure 8 As shown.
[0008] As a further optimization of this solution, the bottom annular flange of the water purification tank system is embedded in a limiting cylinder mounted on the upper platform of the frame assembly. A rubber vibration isolation ring is placed between the upper platform and the bottom annular flange of the tank. The upper platform and the bottom annular flange of the tank are fastened using several sets of bolt assemblies A. Figure 5 As shown.
[0009] As a further optimization of this solution, the circular filter element mounting plate and several stainless steel mesh filter elements mounted on the circular filter element mounting plate in the water purification tank system divide the water purification tank system into a lower volume area and an upper volume area. The lower volume area contains water to be filtered. The water in the lower volume area is filtered by the stainless steel mesh filter elements and enters the upper volume area. The high-frequency vibration generated by the ultrasonic transducer installed at the bottom of the water purification tank causes the water in the lower volume area to generate micro-jet and cavitation phenomena, which peel off impurities and sludge adhering to the outer wall of the stainless steel mesh filter elements, allowing them to enter the water body in the lower volume area and be discharged through the drain solenoid valve and wastewater pipe at the bottom of the water purification tank. Figure 3 , Figure 5 , Figure 8 , Figure 11 As shown.
[0010] The advantages of this invention, an ultrasonic vibration filter self-cleaning water purifier, are as follows: ① This invention uses the high-frequency vibration generated by the ultrasonic transducer to induce micro-jet flow and cavitation in the water inside the water purification tank, which can separate impurities and sludge adhering to the outer wall of the stainless steel mesh filter element. These impurities and sludge are then discharged along with the wastewater from the outlet of the drain solenoid valve at the bottom of the water purification tank, achieving filter element cleaning without disassembly; ② This invention can quickly complete filter element cleaning and wastewater discharge by sequentially controlling the opening and closing of the inlet solenoid valve, the bottom drain solenoid valve, and the start and stop of the ultrasonic generator, saving time and effort compared to manual cleaning.

Detailed Implementation
[0013] An ultrasonic vibration filter self-cleaning water purifier is a water purification device that uses a stainless steel mesh filter for water purification and automatically cleans the stainless steel mesh filter element through ultrasonic vibration. This device is mainly for filtering water with a high impurity content. It mainly consists of three functional components: a frame assembly 10, a water purification tank system 20, and an ultrasonic vibration system 30. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown.
[0014] The frame assembly 10 of the present invention has four central crossbeams 12 welded and installed at the middle position of four supporting columns 11. A central support plate 14 is welded to the four central crossbeams 12. Four upper crossbeams 13 are welded and installed on the upper part of the four supporting columns 11. An upper platform 15 is welded and installed on the upper crossbeams 13. A limiting cylinder 16 is welded and installed around the right circular hole of the upper platform 15. Figure 6 As shown.
[0015] The water purification tank system 20 of the present invention has a top annular flange 212 welded to the top of the water purification tank 211, a bottom annular flange 213 welded to the bottom of the water purification tank 211, a bottom drain threaded pipe 215 welded and installed at the central circular hole at the bottom of the water purification tank 211, the inlet and outlet of the bottom drain solenoid valve 24 respectively connected to the bottom drain threaded pipe 215 and the wastewater discharge pipe 25, a tank inlet threaded pipe 214 welded to the opening on the side of the water purification tank 211, and the inlet and outlet of the inlet solenoid valve 26 respectively connected to the inlet pipe 27 and the tank inlet threaded pipe 214; a tank cover sealing disc flange 222 is welded to the bottom edge of the outer circular surface of the basin-shaped tank cover 221, and the top of the basin-shaped tank cover 221... A top outlet threaded pipe 223 is welded and installed at the opening, and a clean water outlet pipe 28 is connected to the top outlet threaded pipe 223; a circular filter element mounting plate 231 has several circular holes, and the threaded pipe opening at the top of the stainless steel mesh filter element 232 is inserted into each of the circular holes on the circular filter element mounting plate 231 and fastened by the filter element fastening nut 233; a sealing ring 18, a circular filter element mounting plate 231, a sealing ring 18, and a tank cover sealing disc flange 222 are stacked from bottom to top on the circular flange 212 of the tank body and fastened by several sets of bolt assemblies B29; several stainless steel mesh filter elements 232 installed on the circular filter element mounting plate 231 are located in the inner cavity of the clean water tank body 211, such as Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 , Figure 11 As shown.
[0016] The ultrasonic vibration system 30 of the present invention has an ultrasonic generator 31 mounted on the central support plate 14 of the frame assembly 10, and a plurality of ultrasonic transducers 32 fastened to the bottom of the water tank 211 of the water tank system 20. The ultrasonic generator 31 and the ultrasonic transducers 32 are connected by a drive cable 33 to form an ultrasonic drive connection. Figure 2 , Figure 4 , Figure 5 , Figure 8 As shown.
[0017] In the water purification tank system 20 of the present invention, the bottom annular flange 213 of the tank body is embedded in the limiting cylinder 16 mounted on the upper platform 15 of the frame assembly 10. A rubber vibration isolation ring 17 is placed between the upper platform 15 and the bottom annular flange 213 of the tank body. The upper platform 15 and the bottom annular flange 213 of the tank body are fastened by several sets of bolt assemblies A19, such as... Figure 5 As shown.
[0018] In the water purification tank system 20 of the present invention, the circular filter element mounting plate 231 and several stainless steel mesh filter elements 232 mounted on the circular filter element mounting plate 231 divide the water purification tank system 20 into a lower volume area and an upper volume area. The lower volume area contains water to be filtered. The water in the lower volume area is filtered by the stainless steel mesh filter elements 232 and enters the upper volume area. The high-frequency vibration generated by the ultrasonic transducer 32 installed at the bottom of the water purification tank 211 causes the water in the lower volume area to generate micro-jet and cavitation phenomena, which peels off impurities and mud adhering to the outer wall of the stainless steel mesh filter elements 232, allowing them to enter the water body in the lower volume area and be discharged through the drain solenoid valve 24 at the bottom of the water purification tank 211 and the wastewater pipe 25. Figure 3 , Figure 5 , Figure 8 , Figure 11 As shown.
[0019] The working process of an ultrasonic vibration filter self-cleaning water purifier is as follows: The device is installed on a horizontal workbench, and the water supply pipe connected from the water source at a high place is connected to the inlet of the device's inlet pipe 27. The outlet of the device's clean water pipe 28 is connected to the clean water storage tank through a pipe. The device is powered on, the inlet solenoid valve 26 is in the normally open state, the bottom drain solenoid valve 24 is in the normally closed state, and the ultrasonic generator 31 is in the non-working state.
[0020] Unfiltered water from a high-level water source enters the inner cavity of the purified water tank 211 through a pipe via the inlet solenoid valve 26 and fills the inner cavity. Under water pressure, the water in the purified water tank 211 passes through the filter screen attached to the outer wall of the stainless steel mesh filter element 232 and enters the interior of the stainless steel mesh filter element 232. Impurities such as mud and algae are blocked by the filter screen on the outer wall of the stainless steel mesh filter element 232. The filtered water inside the stainless steel mesh filter element 232 enters the basin-shaped tank cover 221 through the threaded pipe at the top of the stainless steel mesh filter element 232, and then flows into the clean water storage tank through the top outlet threaded pipe 223 at the top of the basin-shaped tank cover 221.
[0021] When too many impurities adhere to the outer wall of the stainless steel mesh filter element 232, significantly affecting its filtration speed, the inlet solenoid valve 26 closes, and the ultrasonic generator 31 starts working. The ultrasonic generator 31 drives the ultrasonic transducer 32 installed at the bottom of the water purification tank 211 to emit high-frequency vibrations via the drive cable 33. The generated ultrasonic vibrations cause cavitation in the water inside the water purification tank 211 and generate a jet stream that acts on the stainless steel mesh filter element 232, causing impurities such as mud and algae attached to the outer wall of the stainless steel mesh filter element 232 to be detached and enter the unfiltered water inside the water purification tank 211. After ultrasonic cleaning for a period of time, the ultrasonic generator 31 stops working, the bottom drain solenoid valve 24 opens, and the water containing the detached impurities in the water purification tank 211 is discharged through the bottom drain solenoid valve 24 from the wastewater pipe 25. After the wastewater is discharged, the bottom drain solenoid valve 24 closes, the inlet solenoid valve 26 reopens, and the equipment restarts its filtration function.
