Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water filtering device. Background Art

[0002] Water filtration devices are devices used to improve water quality by filtering, separating, or removing impurities, particulate matter, and pollutants from water, thereby enhancing its cleanliness and suitability. These devices are widely used in many fields, such as industrial production, drinking water treatment, and agricultural irrigation, aiming to protect the environment, maintain ecological balance, and meet human needs for clean water resources.

[0003] In complex water filtration systems, buffer tanks play a crucial role as pretreatment or intermediate storage. They are typically used to temporarily store water to be treated, balancing water flow fluctuations and ensuring the stability of subsequent treatment processes. However, in actual applications, the treated water in the buffer tank is prone to a problem when it passes through the filter cartridge and enters the clean water tank: some water may pass through the gap between the filter cartridge and the cylinder wall and enter the clean water tank without being fully filtered. When the treated water enters the clean water tank through the gap between the filter cartridge and the cylinder wall, it directly affects the outlet water quality and reduces the filtration effect. This may not only increase the burden on subsequent treatment equipment, but may also adversely affect the final water quality, affecting the user experience and health and safety.

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] Example 1

[0029] A water filtering device provided in this embodiment, such as Figure 1-8As shown, in order to conveniently express the internal structure of the device, some of the outer walls of the box, pipes, filter cartridges and other components are omitted in some drawings. A water filtering device includes a buffer bin 1, a clean water bin 2 and a filter cartridge 3. External water to be treated enters the buffer bin 1 through the water inlet 81, and the filtered water flows out of the clean water bin 2 through the water outlet 82. The filter cartridge is driven by the drive gear through the built-in drive motor of the device and then drives the filter cartridge to rotate. A partition 4 is provided between the buffer bin 1 and the clean water bin 2. The filter cartridge 3 is located in the clean water bin 2. One end of the filter cartridge 3 is located at the clean water side 41 of the partition 4. A sealing plate 5 is also included. One end of the sealing plate 5 is connected to the clean water side 41. The sealing plate 5 covers the gap between the filter cartridge 3 and the partition 4 to prevent clean water from flowing directly from the buffer bin 1 into the clean water bin 2 through the gap. The technical solution of this embodiment addresses the common problem in current water filtration devices that when the untreated water passes from the buffer bin through the filter cartridge and enters the clean water bin, it is easy to directly penetrate into the clean water bin through the tiny gap between the filter cartridge and the barrel wall. A key structure, a sealing plate, is creatively introduced. One end of the sealing plate is tightly connected to the clean water side of the partition, forming a seamless barrier, while the other end tightly covers any gap that may exist between the filter cartridge and the partition. This design not only enhances the overall sealing of the filtration system, but also directly and effectively prevents the untreated water that has not been filtered by the filter cartridge from bypassing the normal filtration path and directly penetrating into the clean water bin through the tiny space between the filter cartridge and the barrel wall. Through this innovative solution, the technical solution significantly improves the efficiency and purity of water filtration, and ensures the stability and safety of the water quality in the clean water bin. In order to improve the sealing effect of the device, the sealing plate should have a certain degree of flexibility.

[0030] Preferably, the sealing plate 5 is in close contact with the inner side of the filter cartridge 3. The reason for making the sealing plate in close contact with the inner side of the filter cartridge a further preferred solution is that this design greatly enhances the structural stability and sealing performance of the device. The sealing plate directly fits the inner side of the filter cartridge, effectively eliminating any potential gaps between the filter cartridge and the sealing plate, and further preventing the treated water from penetrating into the clean water tank through these tiny spaces. In addition, the close-fitting design can also reduce the resistance of water flow when passing through the filter cartridge, thereby improving the filtration efficiency. At the same time, this design simplifies the installation and maintenance process, because the direct contact between the sealing plate and the filter cartridge reduces additional fixing components, making the device more compact and easy to maintain.

[0031] Preferably, while the sealing plate 5 is tightly attached to the inner side of the filter cartridge 3, a sealing groove 42 is provided on the clean water side 41. One end of the sealing plate 5 is inserted into the sealing groove 42, and the dimensions of the insert portion of the sealing plate 5 and the sealing groove 42 are matched. This solution is further preferred because the tight fit between the sealing groove and the sealing plate ensures a seamless seal. Following the flow of water, the sealing plate 5 is more easily attached to the inner side of the filter cartridge 3, providing a close seal. The design of the sealing groove provides a precise guide and fixed position for the sealing plate, avoiding the problem of a loose seal caused by installation errors. The matching dimensions of the insert portion and the sealing groove form a reliable mechanical lock after assembly, effectively preventing water from escaping through the gap between them, thereby improving the overall watertightness and filtration efficiency of the system. Furthermore, this structure enhances the durability and vibration resistance of the device, maintaining a stable seal even during long-term operation or external impact. Since water filtration devices have certain water level restrictions, the height of the sealing groove only needs to be above the maximum water level and does not need to completely surround the filter cartridge.

[0032] Preferably, a plurality of groups of threaded through-holes 43 are provided on each side of the sealing groove 42. The addition of threaded through-holes on both sides of the sealing groove is a further preferred option because they provide mounting points for additional fasteners (such as bolts or screws). By adding self-tapping screws to further tighten the sealing plate against the sealing groove of the partition, the connection between the sealing plate and the partition can be further strengthened, preventing loosening or leakage caused by changes in water pressure or long-term use. Furthermore, this design takes into account the subsequent maintenance and upgrades of the device, facilitating easy removal and replacement of the sealing plate or other components when necessary.

[0033] Preferably, the thickness of the sealing plate 5 is 3-6 mm. This thickness range ensures that the sealing plate has sufficient strength and rigidity to withstand the various pressures and water flow impacts that may be generated during the water filtration process. The sealing plate needs to fit tightly between the filter cartridge and the partition to effectively block the penetration of the water to be treated, while a sealing plate that is too thin may not provide sufficient supporting force and is prone to deformation or breakage under long-term use or high water pressure conditions, thereby affecting the sealing effect. In addition, the sealing plate within this thickness range also has good flexibility and elasticity. Sealing materials such as silicone can better adapt to the slight unevenness or installation errors between the filter cartridge and the partition at this thickness, filling these gaps through slight deformation, thereby achieving a tighter seal. This flexibility and elasticity also enables the sealing plate to maintain stable sealing performance when subjected to temperature changes or external shocks, and is not prone to cracks or falling off. In this embodiment, the thickness of the sealing plate 5 is 3 mm, and accordingly, the groove width of the sealing groove 42 is also 3 mm.

[0034] Preferably, a cleaner 6 is provided above the filter cartridge 3, and a drain trough 7 is provided inside the filter cartridge 3. The cleaner 6 is located above the drain trough 7, and the drain outlet 83 of the drain trough 7 is connected to the outside world. In this embodiment, a total of three cleaners are provided in an axial distribution to spray water on the filter cartridge to wash out impurities. The design of combining the cleaner, drain trough and filter cartridge is a further preferred feature of this solution. The setting of the cleaner can automatically clean the filter cartridge regularly, effectively remove the filtered impurities and dirt on the inner surface of the filter cartridge, and maintain the permeability and filtration efficiency of the filter cartridge. The drain trough is responsible for collecting the filtered impurities and dirt generated during the cleaning process and safely discharging them to the outside world through the drain outlet, avoiding the accumulation and backflow of pollutants. During the flushing process, since the filter cartridge rotates continuously, all impurities attached to the inner surface are washed off and fall into the drain trough, and are finally discharged to the outside world through the filtered drain outlet. This automated cleaning and draining mechanism significantly improves the maintenance convenience and work efficiency of the device, while extending the service life and filtration effect of the filter cartridge.

[0035] Preferably, a bottom drain outlet 84 is provided at the bottom of the buffer bin 1 and the clean water bin 2. Adding a bottom drain outlet at the bottom of the buffer bin and the clean water bin is a manifestation of further optimized design. The design of the bottom drain outlet facilitates the centralized collection and treatment of sediments and impurities generated during the filtration process, ensuring the continued purity of the water quality. By regularly opening the bottom drain outlet for sewage discharge operations, it is possible to effectively prevent blockage, corrosion or water quality deterioration caused by long-term accumulation of dirt in the bin. In addition, the bottom drain outlet also facilitates comprehensive cleaning and maintenance of the entire filtration system, thereby improving the reliability and durability of the device. Operators can clean up dirt through the bottom drain outlet without disassembling the entire device, saving time and effort in operation. This design not only improves the filtration effect, but also reduces the complexity and cost of subsequent maintenance.

[0036] Preferably, the material of the sealing plate 5 is silicone. Silicone material has excellent water resistance, high and low temperature resistance, aging resistance and good elasticity, and is very suitable for use as a sealing component in a water filtration device. The silicone sealing plate can maintain stable sealing performance under various complex environmental conditions, effectively preventing water penetration and leakage. At the same time, the softness and elasticity of silicone also enable the sealing plate to better fit the surface of the filter cartridge and the partition, further enhancing the sealing effect. In addition, the silicone material also has good corrosion resistance and chemical resistance, and can resist the erosion of various chemicals and microorganisms that may be present in the water, thereby extending the service life and safety of the sealing plate.
