Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to a composite filter cartridge ultrafiltration water purification device. Background Technology

[0002] Water purification equipment is a device used to purify water, removing impurities, pollutants, microorganisms, etc., to bring the water quality up to a certain standard or improve its quality. It uses filter screens or filter cartridges with different pore sizes, such as PP cotton filter cartridges, activated carbon filter cartridges, ultrafiltration membranes, and reverse osmosis membranes, to intercept and remove suspended solids, sediment, rust, colloids, bacteria, viruses, and other impurities from the water. Depending on the size of the filter cartridge pores, different levels of filtration precision can be achieved. In addition, materials with adsorption capacity, such as activated carbon, can be used to adsorb odors, residual chlorine, organic matter, etc., from the water, improving the taste and odor of the water.

[0003] In existing water purification equipment, the filter cartridges used for water purification are usually installed in a sealed filter cartridge. People pass water to be filtered into the filter cartridge, allowing the water to pass through multiple filter cartridges in sequence to complete the filtration and purification. However, in existing filter cartridges, the filter cartridges are mostly fixed together by adhesive or other means. In order to ensure the sealing effect, the filter cartridge needs to be sealed. This means that when replacing the filter cartridge, people can only remove the entire filter cartridge to replace it. Furthermore, it is inconvenient for people to clean the impurities inside the filter cartridge afterward. Therefore, existing water purification equipment has shortcomings in practical use.

[0004] In conclusion, it is necessary to invent a water purification device using composite filter cartridge ultrafiltration. Utility Model Content

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] See attached document Figures 1-7This utility model provides a composite filter cartridge ultrafiltration water purification device, including a housing 100. A bracket is fixed to the bottom of the outer wall of the housing 100, and a liquid inlet mechanism is provided at the top of the outer wall of the housing 100. A front sealing cover 130 is fixed to the front opening of the outer wall of the housing 100, and a top sealing cover 140 is hinged to the top of the outer wall of the housing 100. The front sealing cover 130 is provided to allow personnel to maintain and disassemble the composite filter cartridge 400 through the front opening after removal, while the top sealing cover 140 is provided to allow maintenance and disassembly of the interior of the primary filtration tank 200 after opening. The liquid inlet mechanism includes a liquid inlet pump 110, the bottom of which is fixed to the top of the outer wall of the top sealing cover 140, and the top liquid inlet end of the liquid inlet pump 110 is connected to a liquid inlet pipe 120. The liquid inlet pump 110 can draw water to be purified through the liquid inlet pipe 120. The interior of the housing 100... A primary filter tank 200 is installed at the top of the wall and below the top sealing cover plate 140. A side block 220 is fixed to the inner wall side of the primary filter tank 200. A metal filter screen 210 for filtering large particulate impurities is set on the inner wall of the primary filter tank 200 and inside the side block 220. The outer wall side of the metal filter screen 210 abuts against the side wall of the side block 220. The side block 220 can overlap the metal filter screen 210 inside the primary filter tank 200. The metal filter screen 210 is mainly used to filter solid impurities in the water to be purified delivered by the inlet pump 110. A booster pump 300 is set at the bottom of the outer wall of the primary filter tank 200. The top suction end of the booster pump 300 is connected to the bottom of the inner wall of the primary filter tank 200. The booster pump 300 is mainly used to deliver the water purified by the metal filter screen 210 to the composite filter cartridge 400 for ultrafiltration.

[0027] Inside the housing 100, below the liquid inlet mechanism, is a purification component for filtering and purifying water. This component includes multiple composite filter cartridges 400, all positioned below the bottom of the outer wall of the booster pump 300. Each composite filter cartridge 400 has a detachable top cover 410 fixed to its outer wall. The composite filter cartridges 400 and the top covers 410 are secured using threaded connections or bolts. This ensures a tight seal between the composite filter cartridges 400 and the top covers 410 while allowing for easy disassembly for cleaning and replacement. The bottom end of the booster pump 300... The liquid end is connected to the top liquid inlet of the upper cover 410 via a water supply pipe. The water supply pipe and the top liquid inlet of the upper cover 410 need to be fixed in a detachable manner. Multiple annular spacers 430 are fixed on the inner wall of the composite filter cylinder 400. The multiple annular spacers 430 are evenly arranged in a ring array. Water passage grooves 431 are opened on the inner wall side of each annular spacer 430. The water passage grooves 431 are mainly to avoid the annular spacers 430 from blocking the purified water, so that the water to be purified can pass through the composite filter layer 440 from the inside to the outside to complete the purification treatment. A composite filter layer 440 for filtration is provided on the inner wall of each annular spacer 430. The composite filter layer 440 is in a ring shape. The composite filter layer 440 is configured such that its sidewalls abut against the outer wall of the annular partition plate 430. The annular partition plate 430 is mainly used to divide the internal space of the composite filter cylinder 400, while the composite filter layer 440 is mainly used to filter and purify the passing water. The composite filter layer 440 is made of PP cotton, activated carbon plate, polyethersulfone, and ultrafiltration membrane layer, arranged sequentially from the inside out. All composite filter layers 440 require a supporting frame to be fixed to their outer walls so that they can abut against the upper annular sealing block 420 without affecting their filtration effect. A short water spray pipe is connected to the center of the bottom of the inner wall of the upper sealing cover 410. This short water spray pipe is used to supply water from the booster pump 300. Purified water is supplied to the inner wall of the composite filter layer 440, allowing the composite filter layer 440 to purify the water sequentially. An upper annular sealing block 420 for pressing is fixed at the bottom of the inner wall of the upper cover 410 and at a position corresponding to each composite filter layer 440. The upper annular sealing blocks 420 are arranged in concentric rings, and their outer walls abut against the inner wall side of the annular spacer 430. The upper annular sealing blocks 420 seal the gaps between adjacent annular spacers 430 when the composite filter cylinder 400 and the upper cover 410 are closed, and simultaneously limit and fix the position of the composite filter layer 440 to prevent it from shaking during filtration. A drain outlet is provided at the bottom of the outer wall side of the composite filter cylinder 400.A main discharge pipe is connected to the bottom of the inner wall of the housing 100, located below the composite filter cartridge 400. The main discharge pipe is connected to the outer wall of the drain outlet via a water supply hose.

[0028] The usage process of this utility model is as follows: First, personnel can assemble and connect the device according to the above instructions. Then, an external power supply is connected to power the water purification equipment. The inlet pump 110 will transport the water to be purified through the inlet pipe 120 and deliver it to the primary filter tank 200. The primary filter tank 200 can filter solid particles in the water through the metal filter screen 210. The filtered water will be transported to the upper cover 410 under the action of the booster pump 300. The upper cover 410 will then transport the purified water to the center of the composite filter cylinder 400 through the water spray pipe. In the composite filter layer 440, PP cotton will first remove colloidal impurities, micro-mud, rust, and other impurities with a particle size greater than 5μm in the water. The water undergoes filtration, and then the activated carbon plate in the composite filter layer 440 exerts its powerful adsorption effect to remove residual chlorine, odor, pigments, and some organic matter from the water, improving the taste and smell of the water and providing better water quality for subsequent fine filtration. After activated carbon adsorption, polyethersulfone can further intercept some small particulate impurities remaining in the water. Utilizing its good mechanical properties and stability, it provides higher quality feed water for the subsequent ultrafiltration membrane, preventing large particles from entering the ultrafiltration membrane layer and avoiding ultrafiltration membrane clogging. Finally, the ultrafiltration membrane layer effectively intercepts impurities such as bacteria, viruses, colloids, and large molecular organic matter in the water. The filtered water will then enter the main discharge pipe through the drain outlet and water supply hose, and be discharged from the main discharge pipe.

[0029] After prolonged use, personnel can first close the valve on the inlet pipe 120 to stop water from entering, then remove the front sealing cover 130, and separate the water supply hose from the drain outlet. Next, the composite filter cartridge 400 can be separated from the upper cover 410 by rotating or unscrewing the fixing bolts. After removing the composite filter cartridge 400, the internal composite filter layer 440 can be extracted one by one for cleaning and replacement. At the same time, personnel can unscrew the bolts fixing the top sealing cover 140, flip the top sealing cover 140, and then remove the metal filter screen 210 and clean the inside of the primary filter tank 200. The inlet pump 110 and inlet pipe 120 should be designed to allow for the movement of the top sealing cover 140 to avoid affecting the rotation of the top sealing cover 140.

[0030] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
