Description

Technical Field

[0001] This utility model belongs to the field of water treatment and environmental protection technology, specifically a filtration device for increasing the transparency of river and lake water. Background Technology

[0002] A filtration device is a unit used to separate solid particles from liquids or gases. In the water treatment field, it is commonly used to purify water, improve transparency, and enhance the ecosystem. Currently, most filtration devices on the market are used in specific applications such as medical, chemical, or air treatment. Their design is primarily geared towards high-precision filtration or the purification of specific fluids, making it difficult to directly meet the large-scale treatment requirements of natural water bodies such as rivers and lakes. Furthermore, existing devices often suffer from low filtration efficiency, clogging susceptibility, and high maintenance costs when dealing with complex water conditions, hindering long-term stable operation and effective improvement of water transparency.

[0003] A search revealed a filtration device with publication number CN113577884B, authorized on April 22, 2025. This device uses a belt drive mechanism to circulate a soft filter screen. A section of the filter screen is immersed in water for interception, and the belt rotation enables automatic replacement and cleaning. While this structure reduces the frequency of filter cleaning and improves continuous operation, it is primarily used for wastewater treatment in the paper industry and relies on fixed installation, making it unsuitable for complex environments such as fluctuating water flow and uneven suspended solids concentration in open water bodies. Furthermore, the device lacks effective measures for removing fine particles or algae, resulting in limited effectiveness in improving the optical clarity of river and lake water.

[0004] Therefore, it is necessary to provide a new filtration device to increase the transparency of river and lake water in order to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a filtration device for increasing the transparency of river and lake water. Compared with existing technologies, during use, river and lake water is introduced into a layered filtration system through a water flow guiding mechanism, utilizing multi-stage filtration components to separate suspended particles of different sizes step by step. Simultaneously, a dynamic cleaning mechanism cleans the filtration components in real time to prevent clogging. This device can adapt to complex water quality conditions and achieve long-term stable operation.

[0006] The filtration device for increasing the transparency of river and lake water provided by this utility model includes a base, a water inlet component, a layered filtration system, and a dynamic cleaning mechanism. A water inlet component for guiding water flow is fixedly installed at one end of the base. A layered filtration system is fixedly installed on the side of the base near the water inlet component. The layered filtration system includes multiple sequentially arranged filtration units, each filtration unit being evenly distributed within the layered filtration system.

[0007] This invention provides a filtration device for increasing the transparency of river and lake water. Compared with existing technologies, during use, a water flow guiding mechanism introduces river and lake water into a layered filtration system, where multi-stage filtration components separate suspended particles of different sizes step by step. Simultaneously, a dynamic cleaning mechanism cleans the filtration components in real time to prevent clogging. This device can adapt to complex water quality conditions and achieve long-term stable operation.

[0008] This utility model provides a filtration device for increasing the transparency of river and lake water, comprising a base, a water inlet assembly, a tiered filtration system, and a dynamic cleaning mechanism. A water inlet assembly for guiding water flow is fixedly installed at one end of the base. A tiered filtration system is fixedly installed on the side of the base near the water inlet assembly. The tiered filtration system includes multiple sequentially arranged filter units, each evenly distributed within the system. An outlet is fixedly installed at the end of the tiered filtration system to discharge the treated water. The dynamic cleaning mechanism is fixedly installed on the side of the base near the tiered filtration system and is used to clean the filter units in real time.

The guide plate is fixedly installed at one end of the base near the water inlet, the diversion channel is fixedly installed below the guide plate, and the regulating valve is installed at the outlet of the diversion channel. The guide plate guides the water flow into the diversion channel, which then distributes the water flow evenly to the outlet.

[0010] In multiple diversion holes, regulating valves control the speed and flow rate of water to ensure that the water flows smoothly into the stratified filtration system.

[0011] Preferably, the filtration unit in the stratified filtration system includes a coarse filter, a fine filter, and an adsorption layer. The coarse filter is fixedly installed at the inlet of the filtration unit, the fine filter is fixedly installed behind the coarse filter, and the adsorption layer is fixedly installed behind the fine filter. The coarse filter is used to intercept larger suspended particles, the fine filter is used to capture smaller particles, and the adsorption layer is used to adsorb organic matter and pigment molecules in the water.

[0012] Preferably, the coarse filter screen has a mesh diameter of 5mm to 10mm, the fine filter screen has a mesh diameter of 0.5mm to 1mm, and the adsorption layer is composed of activated carbon particles. Both the coarse and fine filter screens are made of stainless steel, which has high corrosion resistance and mechanical strength. The adsorption layer thickness is 5cm to 10cm to ensure effective adsorption while avoiding excessive water flow resistance.

[0013] Preferably, the dynamic cleaning mechanism includes a rotating shaft, a scraper, a drive motor, and a drain pipe. The rotating shaft is installed throughout each filter unit of the stratified filtration system, with both ends connected to the side walls of the filter units via bearings.

The drive motor is fixedly installed on the base near the stratified filtration system, and its output shaft is connected to one end of the rotating shaft via a coupling. The drain pipe is fixedly installed at the bottom of the stratified filtration system, with its inlet connected to the bottom of the filter unit. The drive motor rotates the rotating shaft, causing the scraper on the rotating shaft to scrape the inner wall of the filter unit, removing impurities adhering to the filter unit and guiding them out through the drain pipe.

[0014] Preferably, the surface of the scraper is provided with a flexible coating made of silicone material, and the thickness of the flexible coating is 2mm to 3mm. The flexible coating can effectively reduce the friction between the scraper and the inner wall of the filter unit, avoiding damage to the filter unit.

An outlet 16 is located at the end of the stratified filtration system 3. The dynamic cleaning mechanism 4 is fixedly installed on the side of the base 1 near the stratified filtration system 3.

[0024] The specific structure of water inlet component 2 is as follows: Figure 2 As shown, the system includes a guide plate 5, a diversion channel 6, and a regulating valve 7. The guide plate 5 is fixedly installed at one end of the base 1 near the inlet, and the diversion channel 6 is fixedly installed below the guide plate 5. Multiple diversion holes are formed at the bottom of the diversion channel 6, and the regulating valve 7 is installed at the outlet of the diversion channel 6. After water is introduced from the outside, it is first guided by the guide plate 5 into the diversion channel 6. The diversion channel 6 evenly distributes the water flow into the multiple diversion holes. The regulating valve 7 controls the speed and flow rate of the water flow, ensuring that the water flows smoothly into the stratified filtration system 3. The guide plate 5 and the diversion channel 6 are fixed by welding. The diameter of the diversion holes in the diversion channel 6 is 5mm to 10mm. The regulating valve 7 is connected to the outlet of the diversion channel 6, and the opening of the regulating valve 7 can be adjusted manually.

[0025] The specific structure of the stratified filtration system 3 is as follows: Figure 3As shown, its core component consists of multiple filtration units, each including a coarse filter 8, a fine filter 9, and an adsorption layer 10. The coarse filter 8 is fixedly installed at the inlet of the filtration unit, the fine filter 9 is fixedly installed behind the coarse filter 8, and the adsorption layer 10 is fixedly installed behind the fine filter 9. The coarse filter 8 is made of stainless steel with a mesh diameter of 5mm to 10mm, used to intercept larger suspended particles. The fine filter 9 is also made of stainless steel with a mesh diameter of 0.5mm to 1mm, used to capture smaller particles. The adsorption layer 10 is composed of activated carbon particles, with a thickness of 5cm to 10cm, used to adsorb organic matter and pigment molecules in the water. The coarse filter 8, fine filter 9, and adsorption layer 10 are fixed inside the filtration unit by a frame structure, which is connected to the side wall of the filtration unit by bolts. The filtration units are connected by connecting pipes, the two ends of which are connected to the inlet and outlet of the filtration unit by flanges, ensuring that water flows through each filtration unit sequentially.

[0026] The specific structure of the dynamic cleaning mechanism 4 is as follows: Figure 4 As shown, the system includes a rotating shaft 11, a scraper 12, a drive motor 13, a button 14, and a drain pipe 15. The rotating shaft 11 is installed throughout each filter unit of the layered filtration system 3. Both ends of the rotating shaft 11 are connected to the side walls of the filter units via bearings. The scraper 12 is fixedly installed on the outside of the rotating shaft 11, with its edge tightly fitted against the inner wall of the filter unit. The drive motor 13 is fixedly installed on the side of the base 1 near the layered filtration system 3. A button 14 is installed on the drive motor 13 to start or stop the dynamic cleaning mechanism. The output shaft of the drive motor 13 is connected to one end of the rotating shaft 12 via a coupling. The drain pipe 15 is fixedly installed at the bottom of the layered filtration system 3, with its inlet communicating with the bottom of the filter unit. The drive motor 14 drives the rotating shaft 12 to rotate, and the scraper 12 on the rotating shaft 11 scrapes the inner wall of the filter unit, peeling off impurities adhering to the filter unit and guiding them to the drain pipe 15 for discharge. The scraper 12 has a flexible coating made of silicone material with a thickness of 2mm to 3mm. The flexible coating effectively reduces the friction between the scraper 12 and the inner wall of the filter unit, preventing damage to the filter unit. The drain pipe 15 is connected to the bottom of the filter unit via a flange, and the outlet of the drain pipe 15 is connected to an external sewage system.

[0027] The specific structure of outlet 16 is as follows Figure 5 As shown, the inner wall of the outlet is provided with guide vanes 17, which are evenly distributed at the outlet. The guide vanes 17 can guide the water flow and further remove air bubbles and residual particles in the water. The guide vanes 17 are fixed to the inner wall of the outlet 19 by welding, and the outlet 17 is connected to the end of the layered filtration system 3.

[0028] The operation of this utility model is as follows: After the water is introduced from the outside, it is first guided by the guide plate 5 of the water inlet component 2 to the diversion channel 6. The diversion channel 6 evenly distributes the water flow into multiple diversion holes. The regulating valve 7 controls the speed and flow rate of the water flow to ensure that the water flows smoothly into the layered filtration system 3. After the water flows into the layered filtration system 3, it first passes through the coarse filter screen 8 to intercept larger suspended particles, then passes through the fine filter screen 9 to capture smaller particles, and finally passes through the adsorption layer 10 to adsorb organic matter and pigment molecules in the water. During the process of the water flowing through the layered filtration system 3, the drive motor 13 of the dynamic cleaning mechanism 4 drives the rotating shaft 11 to rotate. The scraper 12 on the rotating shaft 11 scrapes the inner wall of the filter unit, peeling off the impurities attached to the filter unit and guiding them to the drain pipe 15 for discharge. Finally, the water flows out through the outlet 16. The guide plate 17 in the outlet 16 guides the water flow, further removing air bubbles and residual particles in the water.

[0029] This invention, through its structural design and operational process, achieves the step-by-step separation of suspended particles of different sizes in river and lake water. The dynamic cleaning mechanism 4 cleans the filter unit in real time, avoiding the clogging problems common in traditional filtration devices. The connections between components are clearly defined, and their placement is rational, ensuring long-term stable operation of the entire device under complex water quality conditions.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] In practical applications, this device was deployed in a water purification project for a lake. The lake had long been polluted by suspended particles and algae, resulting in low transparency and negatively impacting its ecological environment and landscape. To address this problem, the filtration device of this invention was installed on a fixed platform by the lake and connected to the lake water via pipes to achieve continuous purification of the water.

[0032] First, water is introduced from the lake and then enters the inlet component 2. For example... Figure 2 As shown, the guide plate 5 directs the water flow to the diversion channel 6. Multiple diversion holes are located at the bottom of the diversion channel 6 to evenly distribute the water flow among them. A regulating valve 7 is installed at the outlet of the diversion channel 6. Its opening is manually adjusted to control the water flow rate and speed, ensuring a smooth flow into the stratified filtration system 3. The key to this step is that the design of the diversion channel 6 prevents excessive water flow impact from causing localized overload of the stratified filtration system 3. Simultaneously, the regulating valve 7 allows for flexible adjustment of the inlet flow rate according to water quality conditions, thereby improving the adaptability of the device.

[0033] Subsequently, the water flows into the stratified filtration system 3, such as Figure 3As shown, its core component consists of multiple sequentially arranged filtration units. Each filtration unit includes a coarse filter 8, a fine filter 9, and an adsorption layer 10. The coarse filter 8 is made of stainless steel with a mesh diameter of 5mm to 10mm, effectively intercepting larger suspended particles such as leaf fragments and silt. The fine filter 10 has a mesh diameter of 0.5mm to 1mm, further capturing smaller particles, such as tiny silt and organic debris. The adsorption layer 10 is composed of activated carbon particles, with a thickness of 5cm to 10cm, primarily used to adsorb organic matter and pigment molecules in the water, significantly reducing the water's color. Through this step-by-step filtration process, suspended particles of different sizes are gradually separated, ensuring that the water reaches a high level of cleanliness before entering the next stage.

[0034] As water flows through the stratified filtration system 3, the dynamic cleaning mechanism 4 operates synchronously. For example... Figure 4 As shown, the drive motor 13 drives the rotating shaft 11 to rotate, and the scraper 12 on the rotating shaft 11 scrapes the inner wall of the filter unit. The surface of the scraper 12 is coated with a flexible coating made of silicone material with a thickness of 2mm to 3mm, which can effectively reduce the friction between the scraper 12 and the inner wall of the filter unit, while avoiding damage to the filter unit. The scraper 12 peels off the impurities attached to the inner wall of the filter unit and guides them to the drain pipe 15 for discharge. The key to this step is to prevent the filter unit from being clogged due to the accumulation of impurities through the real-time cleaning function of the dynamic cleaning mechanism 4, thereby ensuring that the device can operate stably for a long time under complex water quality conditions.

[0035] Finally, the water flows out through outlet 16. Figure 5 As shown, the inner wall of the outlet 16 is provided with guide vanes 17, which are evenly distributed and can guide the water flow to further remove air bubbles and residual particles in the water. The key to this step is that the design of the guide vanes 17 allows them to separate the tiny air bubbles and particles remaining in the water, thereby further improving the quality of the effluent.

[0036] Through the coordinated operation of the above steps, this invention achieves the step-by-step separation of suspended particles of different sizes in river and lake water, and the dynamic cleaning mechanism 4 cleans the filter unit in real time, avoiding the clogging problem of traditional filter devices. The connections between the components are clear and the layout is reasonable, ensuring that the entire device can operate stably for a long time under complex water quality conditions.
