Description

Technical Field

[0001] This utility model relates to the field of filter equipment technology, specifically a precision filter equipment for pure water preparation. Background Technology

[0002] Pure water preparation refers to the process of removing impurities, ions, and organic matter from water through a series of physical and chemical methods to obtain pure and sterile water. It is commonly used for drinking water, industrial water, and laboratory applications. Special filter membranes are used to filter out macromolecules, colloidal particles, bacteria, etc., while retaining nutrients in the water.

[0003] A search revealed that patent application CN202322344224.1 discloses a precision filter device for pure water preparation, relating to the field of water resource treatment. The device includes a support assembly, a second filter assembly, and a first filter assembly. The support assembly is fixedly installed at the bottom of the second filter assembly. The second filter assembly includes a housing, a first limiting plate, and a filter column. A fixing plate is fixedly installed on the inner wall of the housing, and a corresponding sleeve is fixedly installed on the top of a small hole. The filter column is sleeved on the surface of the sleeve, and a limiting post is fixedly installed on the top of the filter column. The first limiting plate is slidably connected to the inner wall of the housing. This invention provides a precision filter device for pure water preparation. When in use, the sleeve is installed on the fixing plate inside the housing of the precision filter device. The first filter assembly first performs large particle filtration, ensuring thorough filtration. The installation of the limiting plate, straight plate, and bolts, along with the limiting post installed on the top of the filter column for limiting and fixing, makes the filter column more securely fixed.

[0004] However, this patent has its shortcomings. In actual use, after a period of time, a large amount of impurities will accumulate on the filter plates and filter columns, which will affect the filtration efficiency. At this time, it is necessary to stop the pure water filtration work, then disassemble the outer shell of the equipment, and take out the filter plates and filter columns for cleaning and replacement. This requires a lot of cleaning and replacement time and can easily affect the working efficiency of pure water filtration.

[0005] Therefore, we propose a precision filter device for pure water preparation. Utility Model Content

[0022] Please see Figures 1 to 4 This utility model provides a precision filter device for pure water preparation, including a base plate 1, a housing 2 fixedly installed on the base plate 1, an installation groove 12 provided inside the housing 2, a water storage tank 14 provided below the installation groove 12 inside the housing 2, a rotating seat 5 provided inside the installation groove 12, two slots 6 provided inside the rotating seat 5, filter cartridges 7 inserted into each of the two slots 6, filter columns 8 placed at the bottom of each of the two filter cartridges 7, and filter screen frames 9 placed above the filter columns 8 inside each of the two filter cartridges 7, a sliding groove 15 provided to the left of the water storage tank 14 inside the housing 2, a sliding plate 17 slidably connected inside the sliding groove 15, a top rod 16 fixedly installed at the top of the sliding plate 17, the top of the top rod 16 extending to the bottom of the installation groove 12, a rotating component 13 fixedly installed at the bottom of the rotating seat 5, the rotating component 13 rotatably connected inside the housing 2, and a through hole 11 provided at the bottom of the installation groove 12 to the right of the rotating component 13.

[0023] A handle 10 is rotatably connected to the top of the housing 2. The bottom end of the handle 10 is fixedly installed on the rotating seat 5. The handle 10 facilitates the rotation of the rotating seat 5. A water inlet pipe 3 is fixedly installed on the right side of the handle 10 at the top of the housing 2. The water to be filtered is delivered to the filter cartridge 7 through the water inlet pipe 3. An opening 20 is provided on the left side of the handle 10 at the top of the housing 2. A cover plate 19 is inserted into the opening 20. The filter cartridge 7 is inserted into the slot 6 by opening the cover plate 19. The front and rear ends of the cover plate 19 are provided with retaining strips 21. There are two retaining slots 22 in the opening 20. The retaining strips 21 are inserted into the retaining slots 22. The retaining strips 21 can limit the position of the cover plate 19. A pull rod 18 is fixedly installed on the left end of the slide plate 17. The pull rod 18 facilitates the upward pulling of the slide plate 17. The water storage tank 14 is U-shaped. A water outlet pipe 4 is fixedly installed at the front end of the housing 2 corresponding to the water storage tank 14. The water outlet pipe 4 facilitates the discharge of filtered pure water.

[0024] Working principle: During use, the water to be filtered enters the filter cartridge 7 through the inlet pipe 3, and after being filtered by the filter screen frame 9 and filter column 8, it flows into the water storage tank 14 through the perforation 11. When it is necessary to replace or clean the filter screen frame 9 and filter column 8, use the handle 10 to drive the rotating seat 5 to rotate 180 degrees clockwise, so that the spare filter cartridge 7, filter screen frame 9 and filter column 8 are located directly below the inlet pipe 3. Then pull the cover plate 19 to the left to completely expose the opening 20. Use the pull rod 18 to drive the slide plate 17 to rise, so that... The push rod 16 extends into the mounting groove 12 to push the used filter cartridge 7 out of the slot 6, allowing the filter cartridge 7, filter screen frame 9, and filter column 8 containing impurities to be quickly removed for cleaning and replacement. This type of precision filter equipment for pure water preparation is easy to use. With the above components, the filter cartridge 7, filter screen frame 9, and filter column 8 can be replaced and disassembled without stopping the filtration operation, thereby avoiding affecting the working efficiency of pure water filtration. At the same time, the push rod 16 can be used to push the filter cartridge 7 out during disassembly, making it convenient for staff to remove it for cleaning and replacement.
