Description

Technical Field

[0001] This utility model relates to the field of material separation device technology, and in particular to a material separation device based on nanofiltration. Background Technology

[0002] Filtration is a crucial step in ensuring water safety and health, as natural water sources often contain various impurities and harmful substances. These impurities may originate from industrial emissions, agricultural activities, urban sewage, and sediments in the natural environment. For example, industrial emissions may introduce toxic substances such as heavy metals and organic chemicals, agricultural activities may introduce pollutants such as pesticide and fertilizer residues, and urban sewage may contain pathogens and suspended particulate matter. If these pollutants enter the human body directly without treatment, they can cause various diseases, such as heavy metal poisoning and intestinal infectious diseases, posing a serious threat to human health. Furthermore, suspended particulate matter and impurities in water can affect its transparency and taste, reducing its usability. For instance, in household water use, unfiltered water can lead to clogged pipes and scale buildup, affecting the normal supply of household water and the lifespan of equipment. In industrial water use, substandard water quality can cause corrosion and blockages in production equipment, impacting production efficiency and product quality. Therefore, water filtration can effectively remove harmful substances and impurities from water, improve the purity and safety of water, protect people's health and quality of life, and at the same time help protect the environment, reduce water waste and pollution, and ensure the sustainable use of water resources. Water filtration requires the use of filtration equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0024] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a material separation device based on nanofiltration, including multiple filter cylinders 1, a convex ring 8 fixedly connected to the top of the filter cylinder 1, and a groove 9 provided at the bottom of the filter cylinder 1. The convex ring 8 and the groove 9 are used in cooperation. In order to increase the sealing performance, a sealing strip can also be set on the outside of the groove 9 or the convex ring 8.

[0025] In a further design, filter cartridge 1 is filled with filter elements. Multiple filter elements are arranged from top to bottom as PP cotton, activated carbon, and nanofiltration membrane. The filter elements are used to filter liquids, and the filter elements can also be other filter elements.

[0026] Among them, a snap-fit ​​assembly is provided between multiple sets of filter cartridges 1. The snap-fit ​​assembly is used to snap two adjacent filter cartridges 1 together. A limiting assembly is also provided on the outside of the filter cartridge 1 to limit the snap-fit ​​assembly.

[0027] In the specific design, the buckle assembly includes a hanging ring 2 fixedly connected to the outside of the filter cartridge 1 and a mounting base 3. A rotating frame 4 is rotatably connected to the outside of the mounting base 3. A pin 10 is rotatably connected to the mounting base 3. The pin 10 is fixedly connected to the rotating frame 4. A hook 5 is rotatably connected to the outside of the rotating frame 4. Rotating the rotating frame 4 allows the hook 5 to be hooked onto the hanging ring 2. Then, rotating the rotating frame 4 downwards allows the hook 5 to be stably hooked onto the hanging ring 2, thus allowing two adjacent filter cartridges 1 to be securely inserted.

[0028] The limiting components include a fixed base 7 fixedly connected to the outside of the filter cartridge 1, a slider 13 slidably connected to the fixed base 7, and a connecting plate 14 fixedly connected to the outside of the slider 13. A limiting strip 15 is fixedly connected to the outside of the connecting plate 14, and the limiting strip 15 abuts against the outside of the fixed plate 6. The rotating frame 4 is fixedly connected to the outside of the fixed plate 6, which has a positioning groove 11. The fixed base 7 has a sliding opening 17, and a guide rod 12 is fixedly connected inside the sliding opening 17. The guide rod 12 passes through the slider 13 and guides... Rod 12 is used to guide slider 13. Spring 16 is sleeved on the outside of guide rod 12. The slider 13 is pushed upward by the elastic force of spring 16. In order to facilitate contact with fixed plate 6, the length of limit strip 15 is greater than the length of positioning groove 11. The slider 13 is pushed upward by spring 16 until connecting plate 14 is engaged in positioning groove. At the same time, limit strip 15 abuts against the outside of fixed plate 6, and the position of fixed plate 6 is abutted and limited, so that rotating frame 4 will not rotate arbitrarily.

[0029] The method of use in this embodiment is as follows: the liquid to be filtered is delivered into the filter cartridge 1, and the liquid can be fully filtered through the filter element in the filter cartridge 1;

[0030] When a filter cartridge 1 needs to be replaced, first push the slider 13 to slide it down and compress the spring 16 until the limit bar 15 is no longer blocking the outside of the fixing plate 6. Then rotate the rotating frame 4 so that the hook 5 is no longer attached to the hanging ring 2. Using the same principle, the filter cartridge 1 to be replaced can be disassembled and removed.

[0031] Replace the new filter cartridge 1, then rotate the rotating frame 4 to attach the hook 5 to the hanging ring 2. Then, the slider 13 moves upward by the push of the spring 16 until the connecting plate 14 is engaged in the positioning groove. At the same time, the limiting strip 15 abuts against the outside of the fixing plate 6, thus limiting the position of the fixing plate 6.

[0032] In summary, in this embodiment, multiple filter cartridges 1 are integrated into one filter component, which occupies little space and is easy to replace.
