Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, specifically to a deep purification device for water treatment. Background Technology
[0002] Water treatment is the process of removing impurities and pollutants from water or adjusting water quality parameters to meet specific usage standards through physical, chemical, or biological methods. Its core objectives fall into two categories: first, purifying substandard raw water, such as river water, well water, and sewage, into safe drinking water or water that meets the needs of industrial production, agricultural irrigation, and landscaping; second, treating used wastewater and sewage to reduce their pollution levels and ensure they meet discharge standards before being released, thus preventing environmental pollution or achieving water resource recycling.
[0003] In water treatment operations, deep filtration and purification are the core steps to ensure water quality meets standards, and their effectiveness directly determines whether the final effluent can meet stringent standards for drinking water, industrial production, and other applications. Currently, the industry widely employs various filtration membrane technologies for deep purification, including microfiltration membranes that can trap fine particulate matter, ultrafiltration membranes that remove small organic molecules, and reverse osmosis membranes that can precisely separate ions. However, existing filtration equipment has significant shortcomings in actual operation, with the core problem being poor separation and purification effects. Impurities, colloids, or microorganisms in the raw water easily accumulate on the surface of a single filter membrane, quickly causing clogging. This not only significantly reduces overall purification efficiency, leading to decreased treatment capacity and increased energy consumption, but also necessitates frequent shutdowns for filter replacement or cleaning. Utility Model Content
[0004] To solve the above-mentioned problems, this utility model proposes a deep purification device for water treatment that can perform diversion and deep purification and is not prone to clogging of the filter membrane.
[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a deep purification device for water treatment, comprising:
[0006] Base plate;
[0007] A coarse filter box is fixedly installed at one end above the base plate. A filter frame is detachably installed inside. Several filter plates are fixedly installed on the filter frame, and the mesh size of the filter plates increases from top to bottom.
[0008] The diversion pipe rack is fixedly installed on the base plate and connected to the lower end of the coarse filter box through a water pipe. A water pump is fixedly installed on the water pipe.
[0009] The fine filter tank is fixedly installed above the base plate and has several units. The lower end is connected to the diversion pipe frame through a water pipe. The fine filter cylinder is detachably installed inside. Several ultrafiltration membranes are detachably installed inside the fine filter cylinder. The upper end extends out of the fine filter tank and is connected to a flange.
[0010] Furthermore, the filter frame is a U-shaped frame, and the inner wall of the coarse filter box is provided with a guide groove for the filter frame to slide.
[0011] Furthermore, the filter plate is inclined and its edges are fitted against the inner wall of the coarse filter box.
[0012] Furthermore, the diversion pipe support is a U-shaped pipe with both ends sealed.
[0013] Furthermore, the fine filter tanks are equidistantly distributed along the distribution pipe rack.
[0014] Furthermore, the fine filter cartridge is tightly inserted into the fine filter tank from the top, and a sealing ring is provided at the connection point with the fine filter tank.
[0015] Furthermore, the ultrafiltration membranes in each fine filter cartridge are distributed vertically, and a frame is fixedly provided at their edges. The side wall of the fine filter cartridge is provided with an arc-shaped groove for the frame to be tightly inserted, and the side wall of the frame is provided with an inner groove.
[0016] Compared with existing technologies, the advantages of this invention are as follows: After coarse filtration, the water flows through a U-shaped diversion pipe frame and is evenly distributed to multiple fine filtration tanks. The equidistant distribution of the fine filtration tanks ensures stable water inflow and consistent load in each tank, avoiding excessive load on a single tank that could affect the purification effect. Combined with multi-stage progressively larger mesh filter plates for coarse filtration and ultrafiltration membrane-based staged fine filtration, deep treatment is achieved. In the coarse filtration stage, the inclined and inner-wall-fitting multi-stage filter plates first intercept large particles of impurities, reducing the load on the fine filtration. The ultrafiltration membrane in the fine filtration tank is installed through a frame and an arc-shaped groove, allowing for individual disassembly and replacement, timely cleaning of clogged membranes, and the diversion design to prevent overload clogging of a single membrane, thus extending the service life of the filter membrane.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] Combined with appendix Figure 1 A deep purification device for water treatment includes: a base plate 1; a coarse filter box 2, which is fixedly disposed on one end of the base plate 1, and a filter frame 3 is detachably disposed inside. The filter frame 3 is a U-shaped frame. The inner side wall of the coarse filter box 2 is provided with a guide groove for the filter frame 3 to slide, which facilitates the quick disassembly and assembly of the filter frame 3, ensures its stability in the coarse filter box 2, and facilitates subsequent maintenance and replacement of the filter plate 4.
[0024] Combined with appendix Figure 1 Appendix Figure 2 The filter frame 3 is fixedly provided with several filter plates 4, and the mesh size of the filter plates 4 increases from top to bottom. The filter plates 4 are inclined and their edges are attached to the inner wall of the coarse filter box 2, which can extend the water flow filtration path and improve the coarse filtration effect. At the same time, the attachment to the inner wall can ensure sufficient filtration.
[0025] Combined with appendix Figure 1 Appendix Figure 2 The diversion pipe frame 5 is fixedly installed on the base plate 1 and is connected to the lower end of the coarse filter box 2 through the water pipe 6. The water pump 7 is fixedly installed on the water pipe 6. The diversion pipe frame 5 is a U-shaped pipe with both ends sealed, which can evenly distribute the water flow to each fine filter tank 8, ensure stable water intake for each fine filter tank 8, and improve the overall purification efficiency.
[0026] Combined with appendix Figure 1 Appendix Figure 2 The fine filter tanks 8 are fixedly installed above the base plate 1, and there are several of them. The lower end is connected to the distribution pipe frame 5 through the water pipe 2 9. The fine filter tanks 8 are evenly distributed along the distribution pipe frame 5, so that the water flow is more evenly distributed in the distribution pipe frame 5, and the load of each fine filter tank 8 is consistent, thus extending the overall service life of the equipment.
[0027] Combined with appendix Figure 1 Appendix Figure 3 The fine filter tank 8 has a detachable fine filter cartridge 10 inside, with a flange 12 extending out of the fine filter tank 8 at the top. The fine filter cartridge 10 is tightly inserted into the fine filter tank 8 from the top, and a sealing ring is provided at the joint with the fine filter tank 8. This allows for quick assembly and disassembly of the fine filter cartridge 10 while ensuring the airtightness of the joint and preventing leakage of unfiltered water that could affect the purification effect.
[0028] Combined with appendix Figure 3 Appendix Figure 4The fine filter cartridge 10 is detachably equipped with several ultrafiltration membranes 11. The ultrafiltration membranes 11 in each fine filter cartridge 10 are distributed vertically, and a frame 13 is fixedly provided on its edge. The side wall of the fine filter cartridge 10 is provided with an arc-shaped groove 14 for the frame 13 to be tightly inserted. The side wall of the frame 13 is provided with an inner groove 15. The ultrafiltration membrane 11 is installed through the frame 13 and the arc-shaped groove 14. With the inner groove 15, it is easy to disassemble and replace the ultrafiltration membrane 11 individually, reduce maintenance costs, and at the same time ensure the installation stability of the ultrafiltration membrane 11 in the fine filter cartridge 10.
[0029] The specific implementation of this utility model is as follows: Before use, connect the equipment to an external power source and connect the fine filter cartridge 10 to an external water pumping device using a flange. During use, first introduce the water to be treated into the coarse filter box 2. The water flows from top to bottom through several filter plates 4 on the filter frame 3. Because the mesh size of the filter plates 4 increases from top to bottom and they are inclined and fit snugly against the inner wall of the coarse filter box 2, large particles of impurities can be effectively intercepted to complete the coarse filtration. Start the water pump 7. The coarsely filtered water flows through water pipe 1 6 into the distribution pipe frame 5. Under the action of the external water pumping device, the U-shaped distribution pipe frame 5 evenly distributes the water flow to each fine filter tank 8, and the fine filter tanks 8 are equidistantly distributed along the distribution pipe frame 5 to ensure stable water intake in each tank. After the water flows through water pipe 2 9 into the fine filter tank 8, it passes through several ultrafiltration membranes 11 inside the fine filter cartridge 10. The ultrafiltration membranes 11 are fixed to the arc-shaped grooves 14 of the fine filter cartridge 10 through the frame 13, which can deeply filter fine impurities in the water. After purification is complete, turn off the water pump 7. If maintenance is required, the filter frame 3 can be pulled out along the guide groove on the inner side wall of the coarse filter box 2 to replace the filter plate 4. Open the upper end of the fine filter tank 8, take out the fine filter cartridge 10, and then disassemble and replace the ultrafiltration membrane 11 separately through the inner groove 15.
