Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a device for recycling concentrated water in the preparation of purified water. Background Art

[0002] Because tap water contains a large amount of impurities, it cannot be used directly in the medical field. It needs to be purified into medical soft water before it can be used. While providing high-quality pure water equivalent to 50%-75% of the inlet water, it will also produce concentrated water equivalent to 25%-50% of the inlet water. At present, the water production rate of medical water treatment equipment is generally around 50%. The quality of concentrated water obtained after raw water of different water qualities is treated with reverse osmosis technology is also different. Therefore, the treatment method of concentrated water is also different. At this stage in the medical industry, the most commonly used method is to discharge concentrated water directly into the sewer, but it also causes a lot of waste of water resources.

[0003] An existing patent (Announcement No. CN214734600U) discloses a device for recycling and reusing reverse osmosis concentrate from a water purifier. This device monitors the liquid level in the concentrate storage tank. When the level falls below a preset level, the monitoring device outputs an alarm signal. This device recycles and reuses the reverse osmosis concentrate, reducing water waste and water costs while also improving the capacity of the sewage treatment system. During the implementation of this solution, the following problems were discovered in the prior art that have not been adequately addressed:

[0004] During use, the device directly discharges concentrated water, which is often filtered water with a large amount of debris accumulated. Flushing the equipment will cause impurities to remain on the equipment, affecting subsequent use. Secondly, when the concentrated water flows back into the concentrated water tank, the impurities will become mixed again. In addition, when the overflow outlet is used for direct drainage, the drainage volume is small, which can easily lead to unclean drainage, and part of the water will remain inside the overflow outlet. Utility Model Content

[0005] In order to improve the above-mentioned problems that direct discharge of concentrated water easily affects the equipment, impurities are easily mixed with the concentrated water during the concentrated water placement process, and impurities are easily accumulated inside the overflow port when discharged directly from the overflow port, the utility model provides a device for recycling concentrated water in purified water preparation.

[0013] The above technical solution facilitates secondary filtration of impurities in concentrated water through the filter, and the filter is automatically cleaned by turning the lever.

[0014] Optionally, in the above-mentioned device for recycling concentrated water in purified water preparation, the first baffle has an inverted "V"-shaped structure, the first baffle and the linkage rod rotate in an integrated manner, the linkage rod forms an integrated rotating structure with the second baffle through the auxiliary rod, and the second baffle has a "V"-shaped structure.

[0017] Through the above technical solution, the floating layer outside the adsorption magnet can be easily moved up and down, and the limit block is used to ensure the vertical movement of the adsorption magnet.

The spiral fan blade then automatically cleans the filter screen to prevent the filter screen from being blocked, thereby ensuring that the impurities in the water discharged from the outlet pipe are reduced. Secondly, by arranging a first baffle and a second baffle in the center of the filter screen, the impurities are concentratedly precipitated to prevent the impurities from re-mixing with the concentrated water when the concentrated water is injected.

[0022] By providing a closed port on the inner side of the overflow pipe, when too much concentrated water accumulates, the adsorption magnet is driven up by the floating layer until the concentrated water exceeds the closed port, causing the closed port to open, so that a large amount of concentrated water is discharged at one time, ensuring a large amount of concentrated water discharge, thereby avoiding a small amount of concentrated water from accumulating inside the overflow pipe and improving drainage efficiency.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4 The utility model provides an embodiment of a device for recycling concentrated water in purified water preparation, comprising a water purifier 1, a circulation pipe 2 is connected to the right side of the water purifier 1, and the other side of the circulation pipe 2 is connected to the concentrated water tank 3. The interior of the concentrated water tank 3 is connected with a fixed block 7, which is assisted by the fixed block 7 to fix the linkage rod 4, which is convenient for subsequent work. The lower part of the fixed block 7 is connected with a connecting block 6, and the center of the connecting block 6 is connected to the linkage rod 4. The upper part of the linkage rod 4 is connected with a spiral blade 5. The concentrated water impacts the spiral blade 5 to cause it to rotate, so that the linkage rod 4 starts to rotate, realizing non-driving operation. The center of the linkage rod 4 is connected with a toggle rod 9, and the lower part of the toggle rod 9 is connected with a filter screen 8. The filter screen 8 is used to perform secondary filtration on the concentrated water to reduce the amount of impurities discharged. The lower part of the linkage rod 4 is also connected with a first baffle 10, and a second baffle 12 is provided below the first baffle 10. The center of the second baffle 12 is connected with an auxiliary rod 14. The first baffle 10 cooperates with the second baffle 12 to prevent impurities from re-mixing with the concentrated water.

[0030] An outlet pipe 11 is provided on the right side of the concentrated water tank 3, and a sealing valve 13 is provided at the bottom center of the concentrated water tank 3. Impurities are discharged through the sealing valve 13 to facilitate subsequent use. An overflow pipe 16 is provided on the left side of the concentrated water tank 3. The inner side of the overflow pipe 16 is connected to a closing port 17. The overflow pipe 16 is sealed by the closing port 17 to prevent a small amount of concentrated water from being discharged. An adsorption magnet 15 is provided below the closing port 17, and a limiting block 18 is connected above the adsorption magnet 15. An extension block 19 is connected to the center of the limiting block 18. The adsorption magnet 15 is limited by the limiting block 18 and the extension block 19 to ensure its stable lifting.

[0031] See the attached drawings in the specification Figure 1-4 The concentrated water tank 3 and the connecting block 6 are installed in an integrated manner. The connecting blocks 6 are symmetrically distributed on both sides of the center of the fixed block 7. The connection between the fixed block 7 and the linkage rod 4 is a rotational connection. The linkage rod 4 is limited by the fixed block 7 to ensure that the linkage rod 4 moves up and down without affecting its rotation.

[0032] See the attached drawings in the specification Figure 1-4The linkage rod 4 and the spiral fan blade 5 rotate in an integrated manner. The linkage rod 4 and the toggle rod 9 are connected by hot melt. The toggle rod 9 fits tightly against the filter screen 8. The filter screen 8 has a funnel-shaped structure. The impurities in the concentrated water are filtered for the second time through the filter screen 8. At the same time, the filter screen 8 is automatically cleaned by the toggle rod 9.

[0033] See the attached drawings in the specification Figure 1-4 The first baffle 10 is an inverted "V"-shaped structure. The first baffle 10 and the linkage rod 4 rotate in an integrated manner. The linkage rod 4 forms an integrated rotating structure with the second baffle 12 through the auxiliary rod 14. The second baffle 12 is a "V"-shaped structure. The first baffle 10 cooperates with the second baffle 12 to precipitate impurities to the bottom to prevent impurities from being mixed when concentrated water is added.

[0034] See the attached drawings in the specification Figure 1-4 The outside of the adsorption magnet 15 is wrapped with a floating layer. The adsorption magnet 15 forms a sliding structure through the limit block 18 and the extension block 19. The extension block 19 is connected to the concentrated water tank 3 by hot melt connection. The floating layer outside the adsorption magnet 15 moves up and down, and the limit block 18 is used to ensure the vertical movement of the adsorption magnet 15.

[0035] See the attached drawings in the specification Figure 1-4 The closed port 17 and the adsorption magnet 15 are attracted to each other, and the closed port 17 is connected to the concentrated water tank 3 in a sliding manner. The length and width of the closed port 17 are greater than the diameter of the overflow pipe 16. The closed port 17 closes the overflow pipe 16, thereby discharging a large amount of overflow concentrated water at one time.

[0036] Working principle: When in use, first, the water purifier 1 softens the water flow, and the softened water is discharged for medical use. The concentrated water enters the concentrated water tank 3 through the circulation pipe 2. At this time, the concentrated water impacts the spiral fan blades 5, causing the spiral fan blades 5 to rotate. The concentrated water then passes through the filter 8 and enters the concentrated water tank 3. At the same time, impurities fall along the filter 8 and fall above the first baffle 10. Finally, they pass through the first baffle 10 and the second baffle 12 and fall above the sealing valve 13. The toggle rod 9 rotates with the linkage rod 4 to clean the filter 8 to prevent impurities from accumulating. At the same time, the first baffle 10 and the second baffle 12 rotate in the same way, so that impurities are precipitated downward to avoid accumulation on top of them. After long-term use, the sealing valve 13 can be opened to discharge the impurities.

[0037] As mentioned above, during use, the filtered concentrated water is discharged through the outlet pipe 11 for recycling. When the water level rises due to a large amount of concentrated water, it drives the adsorption magnet 15 to rise through the floating layer until the adsorption magnet 15 is adsorbed by the closing mouth 17. When it continues to rise, a large amount of overflowed concentrated water is discharged through the overflow pipe 16 to avoid the concentrated water tank 3 being full. After the overflow, the closing mouth 17 is naturally reset under the action of gravity. The adsorption magnet 15 is limited by the limit block 18 to ensure that it can move up and down.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
