Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a structure for reusing concentrated water from reverse osmosis in a pure water machine. Background Technology

[0002] In the field of pure water production, reverse osmosis (RO) technology is widely used in drinking water purification and industrial pure water production due to its advantages such as high separation precision and effective removal of ions, organic matter, and microorganisms from water. However, reverse osmosis systems suffer from significant water waste during operation. Their working principle dictates that only a portion of the raw water can pass through the reverse osmosis membrane to form pure water, while the remaining approximately 30% to 70% of the raw water becomes concentrated water due to the retention of a large amount of impurities.

[0003] In existing technologies, some water purifiers on the market directly discharge reverse osmosis concentrate. However, this direct discharge of concentrate not only causes serious water resource depletion and reduces water resource utilization, but may also have a certain impact on the environment due to the high concentration of pollutants in the water. This problem is more prominent in water-scarce areas or large-scale pure water production scenarios. Therefore, a reverse osmosis concentrate reuse structure for water purifiers has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structure for reusing concentrated water from reverse osmosis in a pure water machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reverse osmosis concentrate reuse structure for a pure water machine includes a support frame. A water storage tank is fixedly connected to the top of the support frame, and a top plate is fixedly connected to the top of the water storage tank. A drive motor is fixedly connected to the middle of the top of the top plate, and a rotating rod is fixedly connected to the bottom output end of the drive motor through the top plate. Multiple crossbars are fixedly connected to the rotating rod, and a scraper is fixedly connected to the other end of the multiple crossbars. The scraper is adapted to the inner wall of the water storage tank. By rotating the scraper, the inner wall of the water storage tank can be cleaned, extending the service life of the water storage tank. An overflow pipe is fixedly connected to the outer wall of the top of the water storage tank. An adding mechanism is also provided at one end of the top of the top plate. The adding mechanism includes an adding pipe fixedly sleeved at one end of the top of the top plate. A storage pipe is fixedly connected to the top of the adding pipe, and a sealing cap is screwed to the top of the storage pipe. A fifth solenoid valve is fixedly installed on the adding pipe. The addition mechanism facilitates the quantitative addition of cleaning agent into the water storage tank.

[0006] Preferably, a wastewater pipe is fixedly connected to one side of the bottom of the outer wall of the water storage tank, and a first solenoid valve is fixedly installed on the wastewater pipe.

[0007] Preferably, a water pump is fixedly connected to the top of the support frame near the water storage tank, and an output pipe is fixedly connected to the output end of the water pump, while the input end of the water pump is connected to the bottom of the water storage tank through a pipe.

[0008] Preferably, a water inlet pipe is fixedly connected to one side of the outer wall of the water storage tank, and a four-way connector is fixedly connected to the other end of the water inlet pipe. A second solenoid valve is fixedly connected to the water inlet pipe.

[0009] Preferably, a return pipe is fixedly connected to the top of the four-way connector, and a third solenoid valve is fixedly installed on the return pipe.

[0010] Preferably, a drain pipe is fixedly connected to the bottom of the four-way connector, and a fourth solenoid valve is fixedly connected to the drain pipe. A connecting pipe is fixedly connected to the side of the four-way connector away from the water storage tank, and a water quality sensor and a one-way valve are fixedly installed on the connecting pipe.

[0011] The beneficial effects of this utility model are as follows: Thanks to the adoption of technologies such as connecting pipes, return pipes, inlet pipes, storage tanks, and crossbars, the lower concentration concentrated water can return to the water purifier for further filtration, while the higher concentration water enters the storage tank for storage and can be used in non-potable water devices. The storage tank is also easy to clean, preventing scale buildup over time. This effectively solves the problem of insufficient utilization of concentrated water discharged from water purifiers mentioned in the background technology, thereby avoiding waste caused by direct discharge of concentrated water, significantly improving the overall water resource utilization rate of the water purifier, reducing water resource loss, and ensuring stable equipment operation and extended lifespan.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A reverse osmosis concentrate reuse structure for a pure water machine includes a support frame 1. A water storage tank 2 is fixedly connected to the top of the support frame 1, and a top plate 7 is fixedly connected to the top of the water storage tank 2. A drive motor 701 is fixedly connected to the middle of the top of the top plate 7, and a rotating rod 702 is fixedly connected to the bottom output end of the drive motor 701 through the top plate 7. Multiple crossbars 703 are fixedly connected to the rotating rod 702, and the other end of the multiple crossbars 703 is fixedly connected to the same scraper 704. The scraper 704 is connected to the water inside the water storage tank 2. The wall is compatible, and an overflow pipe 205 is fixedly connected to the top outer wall of the water storage tank 2. An adding mechanism 9 is also provided at one end of the top of the top plate 7. The adding mechanism 9 includes an adding pipe 903 fixedly sleeved at one end of the top of the top plate 7. A storage pipe 901 is fixedly connected to the top of the adding pipe 903, and a sealing cap 902 is screwed to the top of the storage pipe 901. A fifth solenoid valve 904 is fixedly installed on the adding pipe 903. Through the setting of the adding mechanism 9, a quantitative amount of cleaning agent can be added to the water storage tank 2.

[0016] In this utility model, a wastewater pipe 201 is fixedly connected to one side of the bottom of the outer wall of the water storage tank 2, and a first solenoid valve 202 is fixedly installed on the wastewater pipe 201. The arrangement of the wastewater pipe 201 and the first solenoid valve 202 allows clean sewage to be discharged into the sewer.

[0017] In this utility model, a water pump 8 is fixedly connected to the top of the support frame 1 near the water storage tank 2, and an output pipe 801 is fixedly connected to the output end of the water pump 8, and the input end of the water pump 8 is connected to the bottom of the water storage tank 2 through a pipe.

[0018] In this utility model, a water inlet pipe 203 is fixedly connected to one side of the outer wall of the water storage tank 2, and a four-way connector 3 is fixedly connected to the other end of the water inlet pipe 203. A second solenoid valve 204 is fixedly connected to the water inlet pipe 203.

[0019] In this utility model, a return pipe 4 is fixedly connected to the top of the four-way head 3, and a third solenoid valve 401 is fixedly installed on the return pipe 4. The top of the return pipe 4 can be connected to the water inlet of the pure water machine.

[0020] In this utility model, a drain pipe 5 is fixedly connected to the bottom of the four-way head 3, and a fourth solenoid valve 501 is fixedly connected to the drain pipe 5. When the inside of the water storage tank 2 is being cleaned, high-concentration wastewater can be discharged into the sewer through the drain pipe 5 and the fourth solenoid valve 501. A connecting pipe 6 is fixedly connected to the side of the four-way head 3 away from the water storage tank 2, and a water quality sensor 602 and a one-way valve 601 are fixedly installed on the connecting pipe 6. The other end of the connecting pipe 6 is connected to the outlet of the pure water machine.

[0021] Working Principle: During operation, all electrical components are connected to a power source via a controller. One end of connecting pipe 6 is connected to the concentrated water pipe of the water purifier, and the top of return pipe 4 is connected to the feed pipe of the water purifier. When the water quality sensor 602 detects the concentration of the concentrated water from the water purifier, the third solenoid valve 401 opens and the second solenoid valve 204 closes, allowing low-concentration water to enter the water purifier for further filtration. When the water quality sensor 602 detects a high concentration of concentrated water, the third solenoid valve 401 closes and the second solenoid valve 204 opens, allowing the concentrated water to enter the storage tank 2 for storage. Simultaneously, the other end of the output pipe 801 is connected to non-potable water-using equipment, such as a sink or toilet. The water pump 8 is activated to deliver the concentrated water. The overflow pipe 205 ensures that when there is a large amount of water in the storage tank 2... The water can be discharged into the sewer through the overflow pipe 205, preventing water from overflowing from the storage tank 2. However, when the storage tank 2 is used for a long time, scale can easily form on its inner wall due to the high calcium and magnesium ions or organic matter content of the concentrated water. In this case, the storage tank 2 needs to be cleaned. At this time, the second solenoid valve 204 closes. When the water purifier produces highly concentrated water, it can be temporarily discharged into the sewer through the opening of the fourth solenoid valve 501. The storage pipe 901 contains neutral detergent. By opening the fifth solenoid valve 904, the detergent in the storage pipe 901 is added into the storage tank 2. Simultaneously, the drive motor 701 is turned on, causing the scraper 704 to rotate via the rotating rod 702 and the crossbar 703, scraping the inside of the storage tank 2 to remove scale. The crossbar 703 at the bottom scrapes the bottom of the storage tank 2. After completion, the wastewater and impurities in the storage tank 2 can be discharged by opening the first solenoid valve 202.
