Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a floating water purification device based on modified photocatalytic nonwoven fabric. Background Technology

[0002] In the current field of water resource protection and water environment management, problems such as eutrophication and excessive organic pollution in water bodies are becoming increasingly prominent, and the demand for purification of natural water bodies and landscape water bodies such as rivers, lakes, and shallow ponds continues to grow. Among traditional water purification technologies, physical filtration methods are prone to efficiency reduction due to filter media clogging, chemical methods may cause secondary pollution, and biological purification methods are greatly affected by environmental temperature and water quality fluctuations. However, photocatalytic purification technology has become a research hotspot in recent years due to its advantages such as no secondary pollution, strong oxidation capacity, and sustainable effects. Among them, modified photocatalytic nonwoven fabrics are gradually being applied to floating water purification devices due to their characteristics such as large specific surface area, good water flowability, and stable photocatalyst loading.

[0003] Existing floating water purification devices, when deployed long-term in eutrophic water bodies such as rivers and lakes, suffer from a continuous buildup of suspended particulate matter, colloids, algae, and microorganisms adhering to the surface of the nonwoven fabric fibers. These pollutants not only physically cover the catalytic sites but also foster the growth of complex biofilms, forming a dense layer of fouling. This fouling layer severely hinders the penetration of visible light, preventing the effective activation of the underlying modified photocatalyst. Consequently, the core photodriven catalytic reaction chain is interrupted, leading to a sharp decline or even complete failure of the device's overall purification efficiency.

[0004] To this end, the applicant proposes a floating water purification device based on modified photocatalytic nonwoven fabric, which aims to solve the problem of surface pollution at its source by integrating a self-cleaning mechanism, and to ensure the long-lasting and stable purification efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a floating water purification device based on modified photocatalytic nonwoven fabric, solving the following technical problem: In existing floating water purification devices, when deployed long-term in eutrophic water bodies such as rivers and lakes, suspended particulate matter, colloids, algae, and microorganisms continuously adhere to the surface of the nonwoven fabric fibers. These pollutants not only physically cover the catalytic sites but also breed complex biofilms, forming a dense layer of dirt. This dirt layer severely hinders the penetration of visible light, preventing the effective activation of the underlying modified photocatalyst, thus interrupting the core photodriven catalytic reaction chain. Consequently, the overall purification efficiency of the device decreases sharply or even fails completely.

[0006] The objective of this utility model can be achieved through the following technical solutions: A floating water purification device based on modified photocatalytic nonwoven fabric includes a mounting frame, on which floats are symmetrically fixed on the upper surface of the mounting frame, and a purification component is connected to the lower part of the mounting frame through an adjustment component. The purification assembly includes a purification box located at the lower end of the adjustment assembly. Multiple filter holes are provided on both side walls and the top wall of the purification box. An L-shaped plate is slidably arranged inside the purification box. Multiple clamping units are arranged in an evenly spaced array on the upper end of the L-shaped plate. The clamping units are used to clamp and fix the non-woven fabric. A cleaning assembly is provided on the L-shaped plate. The cleaning assembly includes a rotating screw rotatably mounted on the upper end of the L-shaped plate. A sliding plate is threadedly connected to the outer surface of the rotating screw. Multiple upright plates are fixedly mounted on the upper surface of the sliding plate. Support rods are fixedly mounted on both sides of the multiple upright plates. A mounting plate is fixedly mounted on one end of each of the multiple support rods. Multiple sets of brushes are provided on the side of the mounting plates and the upright plates on both sides near the non-woven fabric.

[0007] As a further embodiment of this utility model: each clamping unit includes a U-shaped clamping plate symmetrically fixedly disposed on the upper end of the L-shaped plate, a docking block is fixedly disposed on the inner side of the U-shaped clamping plate, and an adjusting screw is threadedly connected to the outer side of the U-shaped clamping plate to its interior, and a U-shaped docking plate adapted to the docking block is rotatably disposed at one end of the adjusting screw. The modified photocatalyst nonwoven fabric body is sandwiched between the docking block and the U-shaped docking plate.

[0008] As a further embodiment of this utility model: a locking block is rotatably provided on one side of the purification box, and the locking block is used to limit the L-shaped plate.

[0009] As a further embodiment of this utility model: a U-shaped frame is symmetrically fixedly arranged on the upper surface of the mounting frame, and the adjustment component includes a lifting adjustment screw threadedly connected to the U-shaped frame. The lower end of the lifting adjustment screw extends to the lower end of the U-shaped frame and is threadedly connected to a lifting sleeve. The lower end of the lifting sleeve passes through the mounting frame and extends to its lower end, where it is fixedly connected to the purification box.

[0010] As a further embodiment of this utility model: the bottom of the purification box is symmetrically provided with U-shaped grooves, and the bottom of the two U-shaped grooves is fixedly provided with slide rails. The lower surface of the L-shaped plate is symmetrically fixedly provided with sliding plates that are compatible with the U-shaped grooves. The lower end of the slide plate is provided with a groove that matches the slide rail.

[0011] As a further embodiment of this utility model: a sleeve plate is symmetrically fixedly provided at the lower end of the mounting bracket, and a connecting plate is slidably engaged inside the sleeve plate, with the lower end of the connecting plate fixedly connected to the upper side wall of the purification box.

[0012] As a further embodiment of this utility model: a collection component is provided at the lower end of the purification box, the collection component includes an inverted ladder-shaped sludge collection box disposed on the bottom surface of the purification box, and a plurality of collection holes communicating with the inverted ladder-shaped sludge collection box are provided on the upper surface of the L-shaped plate.

[0013] As a further embodiment of this utility model: the lower end of the inverted ladder sludge collection box is movably connected to a box door.

[0014] The beneficial effects of this utility model are: (1) This utility model uses a motor to drive a rotating screw, which in turn drives multiple sets of brushes on the sliding plate, vertical plate, and mounting plate to move back and forth. This can comprehensively rub the surface of the modified photocatalyst nonwoven fabric, effectively removing attached suspended impurities, microbial remains, and biofilms, preventing them from covering the catalytic sites and hindering light penetration, thus preventing photocatalyst failure from the source. At the same time, the pollutants swept off can fall into the inverted ladder sludge collection box through the collection hole. Opening the box door allows for centralized cleaning, which not only avoids the backflow of pollutants and causes secondary pollution, but also ensures the long-term stable purification efficiency of the device. (2) This utility model allows the device to float naturally with the water level through the float on the mounting frame. With the adjustment component consisting of the lifting adjustment screw and the lifting sleeve, the underwater height of the purification component can be flexibly adjusted to adapt to water level changes during the wet and dry seasons and waters of different depths such as shallow ponds and lakes, ensuring that the purification unit is always in the effective working layer. On the other hand, the L-shaped plate is slidably connected to the purification box through the slide rail, and with the locking block for limiting, it can be quickly pulled out to replace the non-woven fabric; the clamping unit can firmly fix the non-woven fabric through the adjusting screw, which greatly reduces the difficulty and cost of device installation and maintenance.

[0021] In the field of water treatment technology, floating water purification devices based on modified photocatalytic nonwoven fabrics face severe challenges from surface contamination. When these devices are deployed long-term in eutrophic water bodies such as rivers and lakes, suspended particles, colloids, algae, and microorganisms in the water continuously adhere to the surface of the nonwoven fabric fibers. These pollutants not only physically cover the catalytic sites but also breed complex biofilms, forming a dense layer of dirt. This dirt layer severely hinders the penetration of visible light, preventing the effective activation of the underlying modified photocatalyst. Consequently, the core photo-driven catalytic reaction chain is interrupted, leading to a sharp decline or even complete failure of the overall purification efficiency of the device. To address this, this invention proposes a floating water purification device based on modified photocatalytic nonwoven fabrics, aiming to solve the surface contamination problem at its source by integrating a self-cleaning mechanism, ensuring the long-term and stable purification performance.

[0022] Example 1: Please refer to Figure 1 - Figure 4 As shown, a floating water purification device based on modified photocatalytic nonwoven fabric includes a mounting frame 1. A float 2 is symmetrically fixed on the upper surface of the mounting frame 1, and a U-shaped frame 3 is symmetrically fixed on the upper surface of the mounting frame 1. An adjustment component 4 is provided on the U-shaped frame 3. The adjustment component 4 can flexibly adjust the underwater suspension height of the modified photocatalytic nonwoven fabric purification component 5, thereby adapting to the seasonal changes of high water level during the wet season and low water level during the dry season, while meeting the water depth difference requirements of different water areas (such as shallow ponds and medium-deep lakes), ensuring that the purification unit is always in the effective water layer. The lower ends of the two adjusting components 4 are connected to the same purification component 5. The purification component 5 includes a purification box 51 located at the lower ends of the two adjusting components 4. Multiple filter holes 52 are provided on both side walls and the top wall of the purification box 51. An L-shaped plate 53 is slidably arranged inside the purification box 51. A handle is fixedly installed on one side of the L-shaped plate 53. U-shaped grooves 56 are symmetrically arranged on the inner bottom of the purification box 51. Slide rails 57 are fixedly installed at the bottom of both U-shaped grooves 56. The lower surface of the L-shaped plate 53... The slide plate 58 is fixedly installed on the face and adapted to the U-shaped groove 56. The lower end of the slide plate 58 is provided with a slide groove adapted to the slide rail 57. By cooperating with the slide plate 58 and the slide rail 57, the L-shaped plate 53 can be quickly pulled out. A locking block 54 is rotatably installed on one side of the purification box 51. The locking block 54 is used to limit the L-shaped plate 53 and prevent the L-shaped plate 53 from sliding out of the purification box 51 during water purification. Multiple clamping units 55 are arranged in an evenly spaced array on the upper end of the L-shaped plate 53. In this embodiment, the symmetrically fixed floats 2 on the mounting frame 1 use buoyancy to make the entire device float stably on the surface of the water to be purified, and can float naturally with the water level; the adjustment component 4 on the U-shaped frame 3 can flexibly adjust the underwater suspension height of the purification component 5 to adapt to the water level changes during the high and low water seasons and the water depth differences in different water areas, ensuring that the purification component 5 is always in the effective water layer; during purification, the water first undergoes preliminary physical filtration through the filter holes 52 on the side wall and top wall of the purification tank 51, blocking large suspended impurities from entering. The modified photocatalytic nonwoven fabric, fixed by the clamping unit 55 on the L-shaped plate 53 inside the purification box 51, generates strong oxidizing free radicals under light conditions, decomposes organic pollutants in the water and kills microorganisms to achieve deep purification. The L-shaped plate 53 can be quickly pulled out through the cooperation of the lower U-shaped groove 56 and the slide rail 57 inside the purification box 51. The locking block 54 on one side of the purification box 51 can limit the L-shaped plate 53 to prevent it from sliding out during purification, which not only ensures the stability of the purification process, but also facilitates the subsequent replacement and maintenance of the modified photocatalytic nonwoven fabric. For further details, please refer to Figure 4 As shown, each clamping unit 55 includes a U-shaped clamping plate 551 symmetrically fixedly disposed on the upper end of the L-shaped plate 53. A docking block 552 is fixedly disposed on the inner side of the U-shaped clamping plate 551. An adjusting screw 553 is threadedly connected to the outer side of the U-shaped clamping plate 551 and to its interior. The adjusting screw 553 is threadedly connected to the U-shaped clamping plate 551. A U-shaped docking plate 554 is rotatably disposed on one end of the adjusting screw 553. The U-shaped docking plate 554 is adapted to the docking block 552. The modified photocatalytic nonwoven fabric is snapped together by the snapping of the U-shaped docking plate 554 and the docking block 552. A slot 555 is opened on one side of the U-shaped clamping plate 551. The slot 555 facilitates better insertion of the modified photocatalytic nonwoven fabric. The modified photocatalytic nonwoven fabric body 556 is clamped between the U-shaped docking plate 554 and the docking block 552. In this embodiment, the operator can insert the nonwoven fabric through the slot 555 at one end into the U-shaped clamp 551 and place it between the mating block 552 and the U-shaped mating plate 554 fixed on the inner side, and then pass it out from the slot 555 at the other end. Then, the operator can rotate the adjusting screw 553 that is threaded to the U-shaped clamp 551 to push the U-shaped mating plate 554 to move towards the mating block 552 until the two are engaged, thereby firmly clamping the modified photocatalytic nonwoven fabric body 556 between them and achieving stable fixation of the nonwoven fabric. Modified photocatalytic nonwoven fabric is produced by processes such as sol-gel method, impregnation coating method, or electrospinning method. Modified photocatalytic materials (such as TiO2 modified with metal ions, non-metallic elements, or other semiconductors) are uniformly loaded onto the surface or interior of a nonwoven fabric carrier. After drying and calcination, the modified photocatalyst and nonwoven fabric form a stable bond, while the porous structure of the nonwoven fabric is preserved to ensure water flow. Under natural light (or a specific wavelength light source), the modified photocatalyst on the nonwoven fabric absorbs light energy and is activated. Internal electron transitions form strong oxidizing active species such as hydroxyl radicals and superoxide anion radicals. These active species can react with organic pollutants in the water (such as phenols and pesticide residues) through redox reactions, decomposing them into harmless CO2 and H2O. They can also destroy the cell membranes and genetic material of bacteria and viruses, thereby achieving deep water purification, reducing pollutant concentration, and improving water hygiene. The preparation and working principle of modified photocatalytic nonwoven fabric are existing technologies and will not be described further here.

[0023] Example 2: Based on Example 1, please refer to... Figure 5 As shown, a cleaning assembly 6 is provided on the L-shaped plate 53. The cleaning assembly 6 is used to clean pollutants such as suspended impurities and microbial remains attached to the surface of the modified photocatalytic nonwoven fabric. The cleaning assembly 6 includes a motor 61 mounted on the L-shaped plate 53. A rotating lead screw 62 is mounted on the output shaft of the motor 61. A sliding plate 63 is threadedly connected to the outer surface of the rotating lead screw 62. The sliding plate 63 is slidably positioned below multiple modified photocatalytic nonwoven fabric bodies 556, and the lower end of the sliding plate 63 is engaged with... In the sliding groove on the upper surface of the L-shaped plate 53, multiple vertical plates 64 are fixedly installed on the upper surface of the sliding plate 63. Support rods 65 are fixedly installed on both sides of the multiple vertical plates 64 in the middle. Mounting plates 66 are fixedly installed on one end of the multiple support rods 65. Multiple sets of brushes 67 are evenly spaced on the side of the multiple mounting plates 66 near the modified photocatalyst nonwoven fabric body 556. Multiple sets of brushes 67 are also evenly spaced on the side of the vertical plates 64 near the modified photocatalyst nonwoven fabric body 556. In this embodiment, when it is necessary to clean pollutants such as suspended impurities and microbial remains attached to the surface of the modified photocatalyst nonwoven fabric, the motor 61 drives the rotating screw 62 to rotate; the rotating screw 62 drives the sliding plate 63 to move back and forth, and the multiple upright plates 64 fixed on the upper surface of the sliding plate 63 move synchronously with the sliding plate 63. Among them, the mounting plates 66 connected to the two sides of the middle upright plate 64 by the support rod 65, and the side of the two upright plates 64 near the nonwoven fabric are provided with multiple sets of brushes 67. During the movement of the upright plates 64 with the sliding plate 63, these brushes 67 will interact with the modified photocatalyst. The surface of the photocatalytic nonwoven fabric 556 is fully contacted and rubbed to remove contaminants adhering to the surface of the nonwoven fabric, thus preventing contaminants from clogging the pores of the nonwoven fabric or blocking the photocatalyst, ensuring the purification efficiency of the modified photocatalytic nonwoven fabric. The rotating screw 62 is made of 304 or 316 stainless steel to improve the basic corrosion resistance, and the surface is further treated with hard anodizing or chrome plating to enhance the surface hardness and rust resistance. At the same time, the motor 61 is installed in a protective shell, and the surface of the rotating screw 62 is cleaned regularly to reduce the adhesion of impurities and extend the service life of the equipment. For further details, please refer to Figure 6 As shown, the adjustment assembly 4 includes a lifting adjustment screw 41 threadedly connected to the U-shaped frame 3. The upper end of the lifting adjustment screw 41 is provided with a rotating wheel. The lower end of the lifting adjustment screw 41 extends to the lower end of the U-shaped frame 3 and is threadedly connected to a lifting sleeve 42. The lower end of the lifting sleeve 42 passes through the mounting bracket 1 and extends to its lower end to be fixedly connected to the purification box 51. In this embodiment, the rotating wheel at the upper end of the lifting adjustment screw 41 is rotated to drive the lifting adjustment screw 41 to rotate. Both lifting sleeves 42 are connected to the top of the purification box 51, restricting the rotation of the lifting sleeves 42. This causes the lifting sleeves 42 to move downward relative to the lifting adjustment screw 41, thereby driving the purification box 51 to move downward. This adjusts the underwater suspension height of the modified photocatalytic nonwoven fabric purification component 5, thus adapting to seasonal changes such as high water level during the wet season and low water level during the dry season. It also meets the water depth difference requirements of different water areas (such as shallow ponds and medium-deep lakes), ensuring that the purification unit is always in an effective water layer.

[0024] For further details, please refer to Figure 1 As shown, the lower end of the mounting bracket 1 is symmetrically fixed with sleeve plates 7, and the two sleeve plates 7 are slidably engaged with connecting plates 8. The lower ends of the two connecting plates 8 are fixedly connected to the upper side wall of the purification box 51. In this embodiment, when the lifting sleeve 42 moves the purification box 51 downward, the sleeve plate 7 and the connecting plate 8 can provide motion guidance for the purification box 51. At the same time, the connecting plate 8 can slide relative to the sleeve plate 7 to provide stable guidance for the lifting and lowering movement of the purification box 51, so as to avoid the purification box 51 from shifting or shaking during the height adjustment process, and ensure the smoothness of the adjustment process and the working stability of the purification component 5.

[0025] For further details, please refer to Figure 7 As shown, a collection component 9 is provided at the lower end of the purification box 51. The collection component 9 includes an inverted ladder sludge collection box 91 provided on the bottom surface of the purification box 51. Multiple collection holes 92 are provided on the upper surface of the L-shaped plate 53. The multiple collection holes 92 are connected to the inverted ladder sludge collection box 91. A box door 93 is movably attached to the lower end of the inverted ladder sludge collection box 91. In this embodiment, during water purification and cleaning operations, the brush 67 of the cleaning component 6 sweeps away suspended impurities, microbial remains, and other pollutants attached to the surface of the modified photocatalytic nonwoven fabric body 556. Under gravity, the pollutants fall into the inverted trapezoidal collection box 91 through the collection hole 92. The inverted trapezoidal structure of the inverted trapezoidal collection box 91 guides the pollutants to converge at the bottom of the box, preventing them from accumulating and clogging inside. When the amount of pollutants collected in the inverted trapezoidal collection box 91 reaches a certain level, the operator can quickly clean and discharge the pollutants by opening the movable latched box door 93 at the lower end. This achieves centralized collection and convenient treatment of the pollutants after cleaning, preventing them from flowing back into the water and causing secondary pollution, and ensuring the continuity of the purification effect of the device.

[0026] Example 3: Based on Examples 1 and 2, please refer to... Figure 1 - Figure 7 As shown, the working principle of this utility model is as follows: Water first passes through the filter holes 52 on the purification tank 51 to initially remove large impurities, and then comes into contact with the modified photocatalytic nonwoven fabric body 556 fixed by the clamping unit 55 inside the tank. The nonwoven fabric activates the photocatalyst under light, decomposes organic pollutants and sterilizes to complete deep purification; at the same time, the motor 61 drives the rotating screw 62 to move the sliding plate 63, so that the brushes 67 on the upright plate 64 and the mounting plate 66 rub against the nonwoven fabric to clean the surface pollutants; the cleaned pollutants fall into the inverted ladder sludge collection box 91 through the collection hole 92. The box door 93 is opened regularly for cleaning to avoid secondary pollution and ensure continuous and efficient purification.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
