Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a water purification device that can purify water efficiently. Background Technology

[0002] With rapid industrialization and urbanization, water pollution has become increasingly serious, making the demand for water purification equipment more urgent. Existing water purification equipment has many shortcomings in terms of treatment efficiency, filter lifespan, and maintenance costs, making it difficult to meet the high-quality water requirements of modern industry and daily life. For example, traditional water purification equipment typically uses a single-filter design, which is prone to clogging, leading to decreased purification efficiency. Frequent filter replacements also increase operating costs. Furthermore, filter membrane cleaning and regeneration technologies are not yet perfect, and performance degradation is likely to occur after long-term use. To address these technological bottlenecks, there is an urgent need for a new type of water purification equipment that can achieve high-efficiency purification, intelligent maintenance, and stable operation, thereby overcoming the deficiencies of existing technologies and improving the overall water purification effect.

[0003] To address the aforementioned issues, we propose a water purification device that can efficiently purify water. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a water purification device that can purify water efficiently.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water purification device capable of efficient water purification, comprising a water storage tank with a concave cross-section, wherein the water storage tank is provided with two water purification mechanisms, each of which is composed of three water purification filter elements arranged at equal intervals, each water purification filter element comprising a bottom plate located on the bottom wall of the water storage tank, a lower end plate rotatably connected to the upper end of the bottom plate, an annular structural frame fixedly connected to the upper end of the lower end plate, an upper end plate corresponding to the lower end plate fixedly connected to the upper end of the structural frame, an ultra-microfiltration membrane wrapped around the outside of the structural frame, a lower insertion hole penetrating the bottom plate being opened at the center of the lower end plate, and an upper insertion hole being opened at the center of the upper end plate; The lower end of the water storage tank is fixedly connected to six water suction pipes, which correspond to the positions of six water purification filter elements and are respectively provided with corresponding lower insertion holes at their upper ends. The groove of the water storage tank has communication ports corresponding to the positions of the six water purification filter elements. Two glass boxes are fixedly connected to the groove of the water storage tank, and each glass box is connected to three communication ports. Both glass boxes are provided with backwashing mechanisms. The groove of the water storage tank is provided with a lamp illumination mechanism, and both glass boxes are provided with rotation mechanisms.

[0006] In the aforementioned water purification device that can efficiently purify water, the surface of the ultrafiltration membrane is coated with a photocatalytic material.

[0007] In the aforementioned water purification device that can efficiently purify water, an elastic cover is rotatably connected to the upper end of the lower plate and on the side of the lower insertion hole via a torsion spring shaft.

[0008] In the above-mentioned water purification device that can efficiently purify water, the lower end of the upper plate is fixedly connected to a flushing tube that communicates with the upper insertion hole. Multiple water inlets are opened on the outer circumferential surface of the flushing tube. A movable stopper is slidably connected to the inner wall of the flushing tube. The movable stopper is located above the water inlet and is fixedly connected to the flushing tube by a spring.

[0009] In the aforementioned water purification device capable of efficient water purification, the lower ends of the three suction pipes located on the same side are connected to a water collection pipe. A purified water tank is fixedly connected to the front end of the water storage tank. A first water pump is fixedly installed at the lower end of the water storage tank. The pumping end of the first water pump is connected to the two water collection pipes through a T-connector. A first solenoid valve is installed at the connection points of the T-connector and the two water collection pipes. The outlet end of the first water pump is connected to the purified water tank. A water intake pipe is connected to the front end of the purified water tank.

[0010] In the above-mentioned water purification device that can efficiently purify water, electric telescopic rods are fixedly installed on opposite sides of the two glass boxes. The three base plates located on the same side are fixedly connected by connecting rods. The telescopic end of the electric telescopic rod slides through the upper end face of the groove of the water storage tank and is fixedly connected to the connecting rod on the same side.

[0011] In the aforementioned water purification device that can efficiently purify water, the backwashing mechanism includes three rotating tubes that penetrate the upper end of the glass box and are rotatably connected thereto. The three rotating tubes correspond to the positions of three water purification filter cartridges on the same side. The lower end of the rotating tube is conical, and multiple water outlets are provided on the conical surface. A transmission disc is fixedly sleeved on the part of the rotating tube inside the glass box. A rubber layer is provided on the lower end surface of the transmission disc. The upper ends of the three rotating tubes are connected to a common connecting box. A second water pump is fixedly installed at the front end of the water storage tank. The pumping end of the second water pump is connected to the clean water tank. The outlet end of the second water pump is connected to two connecting pipes. The ends of the two connecting pipes away from the second water pump are respectively connected to two connecting tanks. A second solenoid valve is installed on each of the two connecting pipes.

[0012] In the aforementioned water purification device that can efficiently purify water, the lamp irradiation mechanism includes two opposing movable boxes located in the groove of the water storage tank. Both movable boxes are slidably connected to the inner wall of the groove of the water storage tank via electric slide rails, and ultraviolet lamps are fixedly installed in both movable boxes.

[0013] In the above-mentioned water purification device that can efficiently purify water, the rotating mechanism includes gears fixedly sleeved on each rotating tube, and a rack meshing on one side of each gear. One end of the three racks located on the same glass box is fixedly connected to an end plate, and a telescopic cylinder for driving the end plate to move is fixedly installed on the glass box.

[0014] In the above-mentioned water purification device that can efficiently purify water, both glass boxes are connected to waste discharge pipes, the bottom wall of the water storage tank has a V-shaped cross-section, a sedimentation box is fixedly connected to the lower end of the water storage tank, a plurality of sludge discharge holes connected to the sedimentation box are evenly opened on the bottom wall of the water storage tank, each of the water suction pipes is set through the sedimentation box, and flushing pipes are connected to both the left and right ends of the sedimentation box.

[0015] Compared with existing technologies, the advantages of this invention are: The water purification device of this invention adopts a dual-purification mechanism design, with each mechanism equipped with three synchronously operating water purification filter cartridges, which alternately operate under the control of a first water pump and a solenoid valve. When one set of filter cartridges needs cleaning due to a decline in water quality, the system automatically switches to the other set of filter cartridges to continue working, ensuring uninterrupted water purification and significantly improving water purification efficiency and output. The water tank has a built-in water quality testing instrument that monitors water quality in real time and triggers the switching mechanism to ensure the stability of the output water quality.

[0016] The ultra-microfiltration membrane of the water purifier filter cartridge is coated with a TiO2 / MoS2 heterojunction photocatalytic material. Irradiation with an ultraviolet lamp triggers a photocatalytic reaction, decomposing organic matter and microbial contaminants on the membrane surface. A rotating mechanism ensures uniform ultraviolet irradiation, achieving comprehensive cleaning of the membrane. Compared to traditional chemical cleaning, photocatalytic self-cleaning eliminates the need for chemical agents, preventing membrane corrosion, extending filter cartridge lifespan, and providing sterilization, further enhancing water safety.

[0017] The equipment is equipped with a high-efficiency backwashing mechanism. A second water pump injects high-pressure purified water into the filter element, which, combined with the rotating jet from the rotating pipe, thoroughly removes contaminants from the filter membrane pores. Wastewater generated during backwashing is quickly discharged through a drain pipe to prevent secondary pollution. The bottom of the water storage tank is designed with a V-shaped structure and includes a sedimentation box and sludge discharge hole, allowing large particles to settle naturally. Regular flushing via the flushing pipe reduces the burden on the filter element and further optimizes the water purification effect.

[0018] By combining photocatalytic technology and physical backwashing, the equipment significantly reduces the frequency and energy consumption of chemical cleaning, thereby lowering operating costs. The high flux and antifouling properties of the ultrafiltration membrane, combined with the intelligent cleaning mechanism, ensure the long-term stable operation of the equipment, making it particularly suitable for the purification needs of highly polluted water bodies and providing significant environmental benefits.

[0021] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] Reference Figures 1-10A water purification device with high efficiency includes a U-shaped water storage tank 1 for storing water to be purified. The water storage tank 1 is equipped with two water purification mechanisms, each consisting of three equally spaced water purification filter elements 2. The two water purification mechanisms can perform alternating water purification. During operation, the three water purification filter elements 2 purify water simultaneously, improving water purification efficiency and ensuring water output.

[0023] The water purification filter element 2 includes a base plate 201 located on the bottom wall of the water storage tank 1. A lower end plate 202 is rotatably connected to the upper end of the base plate 201. An annular structural frame 203 is fixedly connected to the upper end of the lower end plate 202. An upper end plate 204 corresponding to the lower end plate 202 is fixedly connected to the upper end of the structural frame 203. An ultrafiltration membrane 205 is wrapped around the outside of the structural frame 203. A lower insertion hole penetrating the base plate 201 is opened at the center of the lower end plate 202, and an upper insertion hole is opened at the center of the upper end plate 204. The ultrafiltration membrane 205 is a hollow fiber membrane module with polyvinylidene fluoride (PVDF) as the core material. It has high porosity, high flux and high antifouling properties. After the water in the water storage tank 1 is filtered by the ultrafiltration membrane 205, large particulate impurities such as silt, rust, colloids and bacteria can be effectively removed.

[0024] An elastic cover 206 is rotatably connected to the upper end of the lower plate 202, on one side of the lower insertion hole, via a torsion spring shaft. The elastic cover 206 can be placed on the lower insertion hole without being affected by external force, thereby sealing the lower insertion hole. A flushing tube 207 communicating with the upper insertion hole is fixedly connected to the lower end of the upper plate 204. Multiple water inlets 208 are opened on the outer circumferential surface of the flushing tube 207. A movable stopper 209 is slidably connected to the inner wall of the flushing tube 207. The movable stopper 209 is located above the water inlets 208 and is fixedly connected to the flushing tube 207 by a spring 210. Under the action of the spring 210, the movable stopper 209 remains in the state above the water inlets 208, so water cannot enter the water filter element 2 through the water inlets 208.

[0025] Six water suction pipes 3 are fixedly inserted through the lower end of the water storage tank 1. The six water suction pipes 3 correspond to the positions of the six water purification filter cartridges 2 and are respectively inserted through the corresponding lower insertion holes at the upper end. Under the action of the water suction pipes 3, the corresponding elastic cover 206 is kept in a lifted state, so the water in the water storage tank 1 can only be filtered through the ultra-micro filter membrane 205 and discharged from the water suction pipes 3.

[0026] Three suction pipes 3 located on the same side are connected at their lower ends to a water collection pipe 4. A purified water tank 7 is fixedly connected to the front end of the water storage tank 1. A first water pump 6 is fixedly installed at the lower end of the water storage tank 1. The pumping end of the first water pump 6 is connected to the two water collection pipes 4 via a three-way pipe 5. A first solenoid valve is installed at each connection point between the three-way pipe 5 and the two water collection pipes 4 to control the alternating operation of the two water purification mechanisms. The outlet end of the first water pump 6 is connected to the purified water tank 7. A water intake pipe is connected to the front end of the purified water tank 7. When purifying water, simply open the first solenoid valve corresponding to the water purification mechanism that needs to be operated, and then start the first water pump 6. The three suction pipes 3 simultaneously generate negative pressure suction, which accelerates the filtration work of the three water purification filter elements 2, thereby filling the purified water tank 7. The user can then take out the purified water through the water intake pipe.

[0027] The water purification tank 7 is equipped with a water quality testing instrument to monitor the quality of the purified water in real time. When the water quality is low, the first solenoid valve will be automatically closed and the first solenoid valve on the other side will be opened to use another water purification mechanism to carry out water purification work, ensuring water purification efficiency.

[0028] The water storage tank 1 has a groove with a communication port 8 corresponding to the positions of six water purification filter cartridges 2. Two glass boxes 9 are fixedly connected to the groove of the water storage tank 1. Each glass box 9 is connected to three communication ports 8. An electric telescopic rod 10 is fixedly installed on the opposite side of each of the two glass boxes 9. The three base plates 201 on the same side are fixedly connected by a connecting rod 11. The telescopic end of the electric telescopic rod 10 slides through the upper end face of the groove of the water storage tank 1 and is fixedly connected to the connecting rod 11 on the same side. The electric telescopic rod 10 can drive the three corresponding water purification filter cartridges 2 to move upward, so that they pass through the communication port 8 and enter the corresponding glass box 9. During the process, the water suction pipe 3 gradually moves out of the lower insertion hole, and the lower insertion hole is then closed by the elastic cover 206.

[0029] Both glass boxes 9 are equipped with backwashing mechanisms. The backwashing mechanism includes three rotating tubes 12 that pass through the upper end of the glass box 9 and are rotatably connected to it. The three rotating tubes 12 correspond to the positions of the three water purification filter elements 2 on the same side. The lower end of the rotating tube 12 is conical, and multiple water outlets 13 are opened on the conical surface. A transmission disc 14 is fixedly sleeved on the part of the rotating tube 12 inside the glass box 9. The lower end of the transmission disc 14 is provided with a rubber layer. The upper ends of the three rotating tubes 12 are connected to a connecting box 15. When the three water purification filter elements 2 are moved into the glass box 9, the lower end disc 202 and the bottom plate 201 can block the corresponding connecting port 8, so that the glass box 9 is closed. At the same time, the lower end of the rotating tube 12 passes through the corresponding upper insertion hole, enters the flushing receiving cylinder 207, and presses down the movable plug disc 209, so that it moves to the position of the water inlet 208. At this time, the water inlet 208 is connected to the water outlet 13 on the rotating tube 12, and the transmission disc 14 remains in the state of blocking the upper insertion hole.

[0030] A second water pump 16 is fixedly installed at the front end of the water storage tank 1. The pumping end of the second water pump 16 is connected to the clean water tank 7, and the outlet end of the second water pump 16 is connected to two connecting pipes 17. The ends of the two connecting pipes 17 away from the second water pump 16 are respectively connected to two connecting boxes 15. A second solenoid valve is installed on each of the two connecting pipes 17. A waste discharge pipe 25 is connected to each of the two glass boxes 9. Specifically, when the water purification filter element 2 to be cleaned enters the glass box 9, the corresponding second solenoid valve above opens, and the second water pump 16 can directly pump the clean water in the clean water tank 7 into the connecting box 15 under high pressure. Then, it is flushed into the three water purification filter elements 2 through the three rotating pipes 12, performing backwashing on the three water purification filter elements 2 at the same time. The wastewater generated during rinsing is directly discharged through the waste discharge pipe 25. After the cleaning work is completed, the electric telescopic rod 10 can drive the three water purification filter elements 2 back down into the water storage tank 1.

[0031] The surface of the ultrafiltration membrane 205 is coated with a photocatalytic material, which is a TiO2 / MoS2 heterojunction. Triggered by ultraviolet or visible light, it can decompose pollutants attached to the ultrafiltration membrane 205, extending its lifespan. Specifically, the TiO2 / MoS2 heterojunction is coated onto the ultrafiltration membrane 205 using a sol-gel method or electrodeposition, and the coating thickness is controlled to balance photocatalytic efficiency and water flux.

[0032] A lamp irradiation mechanism is installed within the recess of the water storage tank 1. This mechanism includes two opposing movable boxes 19 located within the recess of the water storage tank 1. Both movable boxes 19 are slidably connected to the inner wall of the recess via an electric slide rail 18. Each movable box 19 contains a fixed ultraviolet lamp 20. The electric slide rail 18 moves the corresponding movable box 19, allowing the ultraviolet lamp 20 to irradiate the water purification filter element 2 located within the glass box 9. When the photocatalytic material on the surface of the ultra-microfiltration membrane 205 is irradiated by ultraviolet light, a photocatalytic reaction occurs, breaking the van der Waals forces or chemical bonds between pollutants and the membrane surface. This causes the pollutants to desorb from the membrane surface and, in conjunction with the backwashing mechanism, are discharged with the water flow, preventing filter pore blockage. Traditional filter membranes require periodic cleaning with acid / alkali or oxidizing agents, while photocatalytic self-cleaning enables real-time cleaning, reducing the erosion of the filter membrane material by chemical agents and fundamentally solving the problems of easy clogging and short lifespan of traditional filter membranes. It is especially suitable for water sources with high organic matter and high microbial content (such as surface water and industrial wastewater), providing core support for the long-term stable operation of water purification equipment.

[0033] Both glass boxes 9 are equipped with a rotating mechanism, which includes gears 21 fixedly sleeved on each rotating tube 12. Each gear 21 has a rack 22 meshing on one side. The three racks 22 located on the same glass box 9 are fixedly connected to an end plate 23 at one end. A telescopic cylinder 24 is fixedly installed on the glass box 9 to drive the end plate 23 to move. The telescopic cylinder 24 can drive the corresponding rack 22 to move back and forth by telescopically extending and retracting. The rotating tube 12 is rotated by the gears 21. If the water purification filter element 2 is located inside the glass box 9, the friction between the transmission plate 14 and the upper end plate 204 can be used to drive the water purification filter element 2 to rotate. Thus, when the lamp irradiation mechanism is working, the three water purification filter elements 2 are driven to rotate synchronously, so that the ultra-micro filter membrane 205 can be better and more comprehensively irradiated by the ultraviolet lamp 20, thereby better carrying out the photocatalytic reaction and further improving the cleaning efficiency.

[0034] The bottom wall of the water storage tank 1 has a V-shaped cross section. A sedimentation box 26 is fixedly connected to the lower end of the water storage tank 1. Multiple slag holes 27 that communicate with the sedimentation box 26 are evenly opened on the bottom wall of the water storage tank 1. Each suction pipe 3 passes through the sedimentation box 26. Both ends of the sedimentation box 26 are connected to flushing pipes 28. Large particles of impurities that are naturally settled in the water storage tank 1 will gather in the sedimentation box 26, so that the impurities can be directly flushed out by flushing pipes 28 later.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
