Abstract
Description
Technical Field
[0001] The invention belongs to the field of water purification and water quality treatment equipment, and particularly relates to a mass separator. Background Art
[0002] As people's requirements for daily water quality continue to increase, most households now further purify their tap water before use, which has led to the emergence of more and more household water purifiers. The vast majority of water purifiers use filtration to purify water, but the filtration methods and specific filtration processes vary, from the initial single-stage filtration to multi-stage filtration, and the emergence of separators to distinguish different water qualities. It can be said that there are many different types of filtration operations, each with its own advantages and disadvantages.
[0003] Primary filtration, meaning filtering only once, is suitable for situations where water quality requirements are not very high, such as washing vegetables in the kitchen and bathing in the bathroom. However, if you want the water to be drinkable directly, the quality of the water after primary filtration is somewhat unsatisfactory. Therefore, multi-stage filtration water purifiers have emerged. As the name suggests, the water is filtered multiple times so that the filtered water can meet the standard for direct drinking. However, although the water quality is improved after multi-stage filtration, it is a waste for many situations where high water quality is not required. In addition, multi-stage filtration also produces more wastewater, which invisibly creates waste. Therefore, many separators that can produce different levels of water quality according to the situation have begun to be developed one after another. However, most of them only solve the requirements for different levels of water quality, that is, simply lead the water filtered once and the water filtered twice to different pipes respectively. This has resulted in disadvantages such as the separator being large in size, complex pipes, high production costs, and still a lot of wastewater. How to solve the above multiple shortcomings of the separator at one time has become a hot research direction. Summary of the Invention

DETAILED DESCRIPTION
[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0021] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" can include both the "above" and "below" orientations. The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.
[0022] See also Figure 1-15 The present invention provides a technical solution: a separator, the separator is provided with a raw water inlet 1; the raw water inlet 1 is provided with a first flow channel 2 inwardly; the first flow channel 2 is connected to a raw water chamber 4 formed by a lower shell 3; a membrane assembly 5 is provided in the raw water chamber 4; a second flow channel 6 is further provided on the raw water chamber 4; a raw water outlet 7 is provided outwardly from the second flow channel 6; an ultrafiltration water chamber 8 is provided on the upper part of the raw water chamber 4; an ultrafiltration water outlet 9 is provided outwardly from the ultrafiltration water chamber 8; The water chamber 8 is connected inwardly to a third flow channel 10; the third flow channel 10 is an annular channel formed by a reverse osmosis membrane 12 arranged inside and an inner shell 11 arranged outside the third flow channel 10; the reverse osmosis membrane 12 is located at the bottom of the third flow channel 10 and is provided with a sealing ring 13; a capsule 14 is provided on the outside of the inner shell 11 through the upper part of the reverse osmosis membrane 12; 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 outwardly to a pure water outlet 17 through a fourth flow channel 16.
[0023] The raw water inlet 1 is set on one side of the separator. Generally, the tap water outlet and the raw water inlet 1 are connected to each other to serve as the water inlet of the entire separator. The raw water inlet 1 is connected to the first flow channel 2. The first flow channel 2 is set as a downward corner structure to introduce raw water into the raw water chamber 4 formed by the lower shell 3. The raw water is filtered through the membrane assembly 5 in the raw water chamber 4. In some embodiments, the membrane assembly 5 is set as an ultrafiltration membrane wire structure ( Figure 15), ultrafiltration membrane filaments are filled within the annular structure of raw water chamber 4. Unfiltered raw water flows upward through a second flow channel 6 provided on the other side of raw water chamber 4 and out through a raw water outlet 7. The filtered water, after passing through the ultrafiltration membrane filaments, is collected upward into an upper ultrafiltration water chamber 8. Ultrafiltration water chamber 8 contains the primary filtered ultrafiltration water. An ultrafiltration water outlet 9 is provided on the side of ultrafiltration water chamber 8 to draw out the ultrafiltration water for use. To achieve further secondary filtration, ultrafiltration water chamber 8 is further connected to a third flow channel 10 formed by a reverse osmosis membrane 12 and an inner shell 11 outside the reverse osmosis membrane 12. The ultrafiltration water flows through the reverse osmosis membrane 12 to form secondary filtered pure water. The pure water is temporarily stored in a pure water chamber 15 formed by a capsule 14 and the outer wall of the inner shell 11. Under the pressure of the capsule 14, it flows through a downwardly provided fourth flow channel 16 to a pure water outlet 17. The secondary filtered pure water then flows out for direct use.
[0024] Generally speaking, in order to save space and compactly design, the water inlet and three water outlets can be respectively arranged in the four directions of the separator, which is also designed for the convenience of subsequent water pipe installation. The membrane assembly 5 can be selected in a variety of different forms, and the best solution is to adopt ultrafiltration membrane silk, because the impurities that are blocked by the ultrafiltration membrane silk and do not pass through the outside will be enriched on the outer wall of the ultrafiltration membrane silk, and just by the flow of raw water, they will be taken away, and it can be done while filtering and cleaning, and the filtering effect will not be affected by the long filtering time. In order to control the flow direction of water, a sealing ring 13 is set outside the reverse osmosis membrane 12, and the upper and lower parts of the reverse osmosis membrane 12 are artificially divided into different flow channels to create 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 to form a fifth flow channel 18; the fifth flow channel 18 is provided with a first concentrated water outlet 19 inserted into the first flow channel 2 outward.
[0026] The fifth flow channel 18 is further provided with a second concentrated water outlet 20 inserted into the raw water outlet 7 .
[0027] To achieve zero water consumption, the concentrated water that has not been filtered through the reverse osmosis membrane 12 is processed in two parts. One part is introduced into the first flow channel 2 through the first concentrated water outlet 19 to achieve the purpose of repeated filtration. The other part is introduced into the raw water outlet 7 through the second concentrated water outlet 20 and discharged together with the unfiltered raw water for direct use.
[0028] A first diameter change 21 is provided outside the first concentrated water outlet 19 and inside the first flow channel 2 .
[0029] A second diameter change 22 is provided outside the second concentrated water outlet 20 and inside the raw water outlet 7 .
[0030] In order to allow the concentrated water to smoothly enter the circulation filtration or be eliminated from the separator, a first diameter change 21 and a second diameter change 22 are respectively provided on the inner side of the first flow channel 2 and the raw water outlet 7, that is, the inner diameters of the first flow channel 2 and the raw water outlet 7 are reduced, so that the water flow is accelerated. According to the Venturi principle, negative pressure will be generated after the diameter change, which will generate a certain suction force on the concentrated water in the first concentrated water outlet 19 and the second concentrated water outlet 20, assisting its flow and accelerating the water flow rate.
[0031] An upper shell 23 is provided outside the capsule 14. An air filling port 24 is provided on the upper shell 23.
[0032] The pure water obtained by 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 retractable elastic environment for the storage of pure water, and also has a certain effect of 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 at this time. However, in order to prevent the capsule 14 from expanding too much and losing its service life, gas is filled in between the capsule 14 and the upper shell 23 through the inflation port 24. The gas generates a certain pressure, which ensures the long-term use of the capsule 14.
[0033] The outer side of the reverse osmosis membrane 12 is fixed inside the separator by the reverse osmosis membrane connection 25 and the pressure cover 26. In order to strengthen the reverse osmosis membrane 12 and prevent it from moving inside the separator, the reverse osmosis membrane connection 25 and the pressure cover 26 are provided on the outer side.
[0034] A TDS detector 27 is installed outside the pure water outlet 17. In order to monitor the final pure water filtering effect of the separator in real time, a TDS detector 27 is installed outside the pure water outlet 17. TDS is the abbreviation of total dissolved solids, which refers to the concentration of total dissolved solids in water, in milligrams per liter (mg / L), and mainly reflects the Ca content in water. 2+ 、 Mg 2+ 、Na + , K + The concentration of plasma has a good correspondence with the hardness and conductivity of water. The smaller the TDS value, the higher the Ca content in water. 2+ Mg 2+ 、Na + , K + The lower the plasma concentration, the lower the conductivity. Therefore, the TDS value is generally used to measure the purity of pure water.
[0035] The reverse osmosis membrane 12 is a cylindrical structure, with a reverse osmosis membrane outer flow channel 121 provided on its outer side; a multi-layer reverse osmosis membrane filtration membrane body 122 is provided on the inner side of the reverse osmosis membrane filtration membrane body 122; a reverse osmosis membrane inner flow channel 123 is formed inside the reverse osmosis membrane filtration membrane body 122; and a plurality of filtered water collection ports 124 are provided on the reverse osmosis membrane inner flow channel 123.
[0036] In some embodiments, water enters the reverse osmosis membrane 12 through the reverse osmosis membrane outer flow channel 121 and then is filtered through the reverse osmosis membrane filter body 122. The filtered water enters the reverse osmosis membrane inner flow channel 123 through the filtered 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, passes through the corner of the first flow channel 2, and flows into the lower raw water chamber 4, where it undergoes a primary filtration. Unfiltered raw water flows upward through the second flow channel 6 on the other side, and exits the separator at the raw water outlet 7 for use in water environments that do not require filtration, such as bathrooms. Water filtered by the membrane assembly 5 in the raw water chamber 4 flows upward into the ultrafiltration water chamber 8. The ultrafiltration water that flows from the ultrafiltration water chamber 8 to the ultrafiltration water outlet 9 is the primary filtered water and can be used in water environments that require filtered water, such as kitchens. In addition, a portion of the water in the ultrafiltration water chamber 8 flows upward through the third flow channel 10 and reaches the upper part of the reverse osmosis membrane 12. The water flows from top to bottom through the reverse osmosis membrane outer flow channel 121 outside the reverse osmosis membrane 12, and part of the water flows through the reverse osmosis membrane filter membrane body 122 and enters the reverse osmosis membrane inner flow channel 123 through the filtered water collection port 124 to obtain secondary filtered pure water. Since the lower part of the reverse osmosis membrane inner flow channel 123 is sealed, the water can only flow upward again into the pure water chamber 15. The capsule 14 expands due to water pressure and eventually reaches a balance point with the gas pressure inside the upper shell 23 and outside the capsule 14. The pure water flows in the pure water chamber 15 of the capsule 14 to the fourth flow channel 16, and finally flows out from the pure water outlet 17 to the use environment where secondary filtered water is required, such as the direct drinking water pipe in the kitchen. The water that doesn't pass through reverse osmosis membrane 12 is called concentrate. This concentrate has two destinations: First, a portion of the concentrate flows through fifth flow channel 18 and enters first concentrate outlet 19. This outlet is inserted into first reducer 21 of first flow channel 2. Due to the Venturi principle, this concentrate can be effectively mixed with the raw water for circulation and filtration. Second, another portion of the concentrate flows through fifth flow channel 18 and enters second concentrate outlet 20. This outlet is inserted into second reducer 22 of raw water outlet 7. Also due to the Venturi principle, this concentrate can be effectively mixed with the raw water for discharge and use.
