Description

Technical Field

[0001] This utility model belongs to the field of water purification and water treatment equipment, and specifically relates to a separator. Background Technology

[0002] As people's demands for the quality of their daily drinking water continue to increase, most households now purify their tap water before using it. This has led to an increasing number of household water purifiers appearing in people's lives. Most water purifiers use filtration to purify water, but the filtration methods and processes vary. From single-stage filtration to multi-stage filtration, and even water separators designed to differentiate between different water qualities, there are numerous types of filtration systems, each with its own advantages and disadvantages.

[0003] Single-stage filtration, meaning filtering only once, is suitable for situations where water quality requirements are not very high, such as washing vegetables in the kitchen or showering in the bathroom. However, if you want water to be directly drinkable, the quality of water after single-stage filtration is somewhat unsatisfactory. Therefore, multi-stage filtration water purifiers have emerged. As the name suggests, they filter water multiple times, resulting in water that meets direct drinking standards. However, while multi-stage filtration improves water quality, it is wasteful for many situations where high water quality is not required, and it also generates more wastewater, thus creating further waste. Consequently, many water separators that can produce different levels of water quality based on specific needs have been developed. However, most of these only address the different water quality requirements, simply separating the water from the first and second filtrations into different pipes. This leads to drawbacks such as large size of the separators, complex piping, high production costs, and still significant wastewater generation. How to solve all these drawbacks of water separators in one go has become a hot research topic. Utility Model Content

[0022] Please see Figure 1-15 This utility model provides a technical solution: a separator, which includes a raw water inlet 1; a first flow channel 2 is provided inward from the raw water inlet 1; the first flow channel 2 is connected to a raw water chamber 4 formed by a lower shell 3; a membrane module 5 is provided inside the raw water chamber 4; a second flow channel 6 is also provided on the raw water chamber 4; a raw water outlet 7 is provided outward from the second flow channel 6; an ultrafiltration water chamber 8 is provided at the upper part of the raw water chamber 4; and an ultrafiltration water outlet 9 is provided outward from the ultrafiltration water chamber 8; The water filtration chamber 8 is connected to a third flow channel 10; the third flow channel 10 is an annular channel formed by the reverse osmosis membrane 12 disposed inside and the inner shell 11 disposed outside; the reverse osmosis membrane 12 is provided with a sealing ring 13 at the bottom of the third flow channel 10; the upper part of the reverse osmosis membrane 12 passes through the outer side of the inner shell 11 and is provided with a capsule 14; the inner side of the capsule 14 and the outer side of the inner shell 11 form a pure water chamber 15; the pure water chamber 15 is connected to a pure water outlet 17 through a fourth flow channel 16.

[0023] The raw water inlet 1 is located on one side of the separator. Generally, the tap water outlet is connected to the raw water inlet 1, serving as the inlet for the entire separator. The raw water inlet 1 is internally connected to a first flow channel 2, which is a downward-facing corner structure that introduces raw water into the lower raw water chamber 4 formed by the lower shell 3. The raw water is filtered within the raw water chamber 4 by a membrane module 5. In some embodiments, the membrane module 5 is an ultrafiltration membrane fiber structure. Figure 15The ultrafiltration membrane fibers are filled inside the annular structure of the raw water chamber 4. Unfiltered raw water flows upward through the second flow channel 6 on the other side of the raw water chamber 4 and out through the raw water outlet 7. Filtered water passes through the ultrafiltration membrane fibers and collects upward into the ultrafiltration water chamber 8 located at the top. The ultrafiltration water chamber 8 contains ultrafiltration water that has undergone primary filtration. An ultrafiltration water outlet 9 is located on the side of the ultrafiltration water chamber 8 to lead out ultrafiltration water for use. To achieve further secondary filtration, the ultrafiltration water chamber 8 is also connected to the third flow channel 10 formed by the reverse osmosis membrane 12 and its outer inner shell 11. The ultrafiltration water flows through the reverse osmosis membrane 12 for further filtration, forming secondary filtered pure water. The pure water is temporarily stored in the pure water chamber 15 formed by the capsule 14 and the outer wall of the inner shell 11. Under the pressure of the capsule 14, it flows downward through the fourth flow channel 16 to the pure water outlet 17. The secondary filtered pure water flows out for direct use.

[0024] To save space and create a compact design, the inlet and three outlets can typically be positioned on the four sides of the separator, facilitating subsequent water pipe installation. The membrane module 5 can be selected from various forms, but the optimal solution is to use ultrafiltration membrane fibers. Impurities blocked on the outside of the ultrafiltration membrane fibers accumulate on their outer wall, which is then carried away by the flow of raw water. This allows for simultaneous filtration and cleaning, ensuring the filtration effect is not affected by prolonged filtration time. To control water flow, a sealing ring 13 is installed on the outside of the reverse osmosis membrane 12, artificially dividing the upper and lower parts of the membrane 12 into different flow channels, thus creating conditions for subsequent water flow control.

[0025] The reverse osmosis membrane 12 is located at the lower part of the sealing ring 13 and the lower part of the inner shell 11, forming a fifth flow channel 18; the fifth flow channel 18 is provided with a first concentrate outlet 19 inserted into the first flow channel 2.

[0026] The fifth flow channel 18 is also provided with a second concentrated water outlet 20 that is inserted into the raw water outlet 7.

[0027] To achieve zero water consumption, the concentrate that has not been filtered through the reverse osmosis membrane 12 is treated in two parts. One part is introduced into the first flow channel 2 through the first concentrate outlet 19 to achieve repeated filtration. The other part is introduced into the raw water outlet 7 through the second concentrate outlet 20 and discharged together with the unfiltered raw water for direct use.

[0028] A first diameter reducer 21 is provided on the outside of the first concentrate outlet 19 and on the inside of the first flow channel 2.

[0029] A second reducer 22 is provided on the outside of the second concentrate outlet 20 and on the inside of the raw water outlet 7.

[0030] To ensure that the concentrate can smoothly enter the circulating filter or be discharged from the separator, a first diameter changer 21 and a second diameter changer 22 are respectively installed inside the first flow channel 2 and the raw water outlet 7. That is, the inner diameter of the first flow channel 2 and the raw water outlet 7 is reduced, so that the water flows through faster. According to the Venturi principle, a negative pressure will be generated after the diameter change, which will generate a certain suction force on the concentrate in the first concentrate outlet 19 and the second concentrate outlet 20, assisting its flow and accelerating the flow rate.

[0031] An upper shell 23 is provided on the outside of the capsule 14. An inflation port 24 is provided on the upper shell 23.

[0032] The pure water obtained through two filtrations is temporarily stored in the pure water chamber 15. The inner side of the pure water chamber 15 is the inner shell 11, and the outer side is the capsule 14. The capsule provides a flexible environment for storing pure water and also has a certain effect on regulating the internal pressure of the separator. When only pure water is used, the pressure in the pure water chamber 15 will increase, and the capsule 14 will expand. However, in order to prevent the capsule 14 from expanding too much and shortening its service life, gas is introduced between the capsule 14 and the upper shell 23 through the air inlet 24. The gas generates a certain pressure, ensuring the long-term use of the capsule 14.

[0033] The reverse osmosis membrane 12 is fixed inside the separator via a reverse osmosis membrane connector 25 and a pressure cap 26. The reverse osmosis membrane connector 25 and pressure cap 26 are provided on its outer side to reinforce the reverse osmosis membrane 12 and prevent it from shifting inside the separator.

[0034] A TDS detector 27 is installed outside the pure water outlet 17. To monitor the filtration effect of the pure water produced by the separator in real time, a TDS detector 27 is installed outside the pure water outlet 17. TDS is an abbreviation for Total Dissolved Solids, which refers to the concentration of total dissolved substances in water, measured in milligrams per liter (mg / L). It primarily reflects the concentration of calcium in the water. 2+ Mg 2+ Na + K + The concentration of plasma has a good correlation with water hardness and conductivity; the lower the TDS value, the higher the calcium content in the water. 2+ Mg 2+ Na + K + The lower the plasma concentration, the lower the conductivity. Therefore, TDS value is generally used to measure the purity of purified water.

[0035] The reverse osmosis membrane 12 has a cylindrical structure and an external flow channel 121 is provided on its outer side. Multiple layers of reverse osmosis membrane filter body 122 are provided inside the external flow channel 121. An internal flow channel 123 is formed inside the reverse osmosis membrane filter body 122. Multiple filter water collection ports 124 are provided on the internal flow channel 123.

[0036] In some embodiments, water enters through the reverse osmosis membrane 12 via the external flow channel 121 and is then filtered through the reverse osmosis membrane filter body 122. The filtered water then enters the internal flow channel 123 of the reverse osmosis membrane through the water collection port 124 and flows upward to the pure water chamber 15.

[0037] Working principle: Raw water flows into the separator from the raw water inlet 1, and flows down to the raw water chamber 4 through the corner of the first flow channel 2. It undergoes primary filtration in the raw water chamber 4. The unfiltered raw water flows upward through the second flow channel 6 on the other side and exits from the raw water outlet 7. This raw water is then supplied to water environments that do not require filtration, such as bathrooms. Water filtered by the membrane module 5 in the raw water chamber 4 flows upward into the ultrafiltration water chamber 8. The ultrafiltration water flowing from the ultrafiltration water chamber 8 to the ultrafiltration water outlet 9 is water that has undergone primary filtration and can be introduced into water environments requiring filtration, such as kitchens. In addition, some water in the ultrafiltration water chamber 8 flows upward through the third flow channel 10 to the upper part of the reverse osmosis membrane 12. The water flows from top to bottom through the reverse osmosis membrane external flow channel 121 outside the reverse osmosis membrane 12. Some water flows through the reverse osmosis membrane filter body 122 and enters the reverse osmosis membrane internal flow channel 123 through the filter water collection port 124 to obtain pure water that has been filtered twice. Since the lower part of the reverse osmosis membrane internal flow channel 123 is sealed, the water can only flow upward again to the pure water chamber 15. The capsule 14 expands due to water pressure and eventually reaches an equilibrium point with the gas pressure inside the upper shell 23 and outside the capsule 14. The pure water flows into the fourth flow channel 16 in the pure water chamber 15 of the capsule 14 and finally flows out from the pure water outlet 17 to the environment where water needs to be filtered twice, such as the direct drinking water pipe in the kitchen. The water that does not pass through the reverse osmosis membrane 12 is concentrated water. This concentrated water has two destinations: First, a portion of the concentrated water enters the first concentrated water outlet 19 through the fifth channel 18, which is inserted into the first reducer 21 of the first channel 2. Due to the Venturi principle, the concentrated water can mix well with the raw water for circulation filtration. Second, another portion of the concentrated water enters the second concentrated water outlet 20 through the fifth channel 18, which is inserted into the second reducer 22 of the raw water outlet 7. Again, due to the Venturi principle, the concentrated water can mix well with the raw water before being discharged for use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
