[0024] The new clean wall-mounted micro-wastewater energy-saving commercial RO reverse osmosis water supply equipment includes a shell 1, a pretreatment unit 2 and a RO micro-wastewater membrane 5. The inner surface wall of the bottom of the shell 1 is fixedly connected to a wastewater pipe 14, a pure water pipe 15 and a water inlet pipe 16. The water inlet pipe 16 is connected to the input end of the pretreatment unit 2 for transmission. A low-pressure switch 4, a raw water solenoid valve 6, and a six-chamber booster pump 9 are integrated in sequence between the pretreatment unit 2 and the input end of the RO micro-wastewater membrane 5. The output end of the RO micro-wastewater membrane 5 includes a pure water outlet and a wastewater outlet. A one-way valve 11, a flow meter 12 and a high-pressure switch 13 are integrated in sequence between the pure water outlet and the pure water pipe 15. A wastewater solenoid valve 7 is integrated between the wastewater outlet and the wastewater pipe 14, and a reflux component is provided between the six-chamber booster pump 9 and the wastewater solenoid valve 7;

[0025] The raw water enters the pipeline and flows through the pressure reducing valve 3, which can prevent the raw water pressure from being too high and the water hammer high-pressure movement. Then, after the raw water passes through the PP polypropylene spray-melt filter element 201, the crystal carbon filter element 202 and the carbon rod filter element 203 in sequence, the raw water low-pressure switch 4 is opened, and the raw water flows through the raw water solenoid valve 6. Under the action of the six-chamber booster pump 9, it is introduced into the RO micro-wastewater membrane 5 for further purification. Then the one-way valve 11 and the high-pressure switch 13 are opened, and the pure water will be discharged to the water storage tank outside through the pure water pipe 15, while the concentrated water will be discharged through the wastewater pipe 14, thereby achieving energy-saving purification of the raw water, canceling the traditional four-stage filtration device, and separating the water storage tank from the shell 1, thereby ensuring energy-saving purification of the water body while reducing the overall volume of the equipment, so as to facilitate the wall-mounted installation of the equipment, and the RO micro-wastewater membrane 5 can be automatically backwashed and cleaned through the energy storage core 201, thereby improving the convenience of using the wall-mounted micro-wastewater energy-saving commercial RO reverse osmosis water supply equipment.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the reflux component includes a reflux proportional valve 8, which is connected between the wastewater solenoid valve 7 and the input end of the six-chamber booster pump 9. After the concentrated water precipitated by the RO micro-wastewater membrane 5 treating the raw water is discharged, the concentrated water that can be reused can be reintroduced into the RO micro-wastewater membrane 5 under the action of the reflux proportional valve 8 and the six-chamber booster pump 9, while the concentrated water that cannot be reused is directly discharged through the wastewater pipe 14, thereby further improving the energy saving performance of the wall-mounted micro-wastewater energy-saving commercial RO reverse osmosis water supply equipment.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the shell 1 is fixedly connected to an energy storage core 10, and the output end of the energy storage core 10 is connected to the inside of the RO micro-wastewater membrane 5 to achieve backwash cleaning of the RO micro-wastewater module 5. As for the specific structure of this component, the reference is made to the "Backwash Energy Storage Core for Reverse Osmosis Water Purifier" submitted by the applicant in the previous order;

[0028] It should be noted that the RO micro-wastewater module 5, raw water solenoid valve 6, wastewater solenoid valve 7, reflux proportional valve 8, six-chamber booster pump 9, energy storage core 10 and one-way valve 11 here are a set of RO reverse osmosis water purification modules. The RO micro-wastewater module 5 of the main part refers to the technology in the micro-wastewater energy-saving RO reverse osmosis water purifier with publication number CN206828244U. The number of modules can be increased or decreased according to demand.

[0029] Specifically, such as Figure 1 and Figure 2As shown, the shell 1 is made of stainless steel, the pure water pipe 15 and the waste water pipe 14 are both PE pipes, and the water inlet pipe 16 is a corrugated pipe, which ensures the stability of the water supply equipment. The pretreatment unit 2 includes a PP polypropylene spray-melt filter element 201, a crystal carbon filter element 202 and a carbon rod filter element 203. The PP polypropylene spray-melt filter element 201 removes suspended matter such as mud, rust, and colloid in the water. The crystal carbon filter element 202 removes residual chlorine, organic matter, color, odor, odor, colloid and suspended matter in the water. The carbon rod filter element 203 removes residual chlorine, organic matter, color, odor, odor, and colloid in the water. A pressure reducing valve 3 is integrated between the water inlet pipe 16 and the PP polypropylene spray-melt filter element 201 to prevent excessive raw water pressure and water hammer high-pressure movement.

[0030] Working principle: Raw water enters the pipeline and flows through the pressure reducing valve 3, which can prevent the raw water pressure from being too high and the water hammer high-pressure movement. Then the raw water passes through the PP polypropylene spray-melt filter element 201, the crystal carbon filter element 202 and the carbon rod filter element 203 in turn. The raw water low-pressure switch 4 is turned on, and the raw water flows through the raw water solenoid valve 6. Under the action of the six-chamber booster pump 9, it is introduced into the RO micro-wastewater membrane 5 for further purification. Then the one-way valve 11 and the high-pressure switch 13 are turned on, and the pure water will be discharged to the water storage tank outside through the pure water pipe 15, while the concentrated water will be discharged through the wastewater pipe 14, thereby realizing energy-saving purification of raw water, canceling the traditional four-stage filtration device, and separating the water storage tank and the shell 1. , thereby ensuring energy-saving purification of the water body while reducing the overall volume of the equipment, so as to facilitate the wall-mounted installation of the equipment, and the RO micro-wastewater membrane 5 can be automatically backwashed and cleaned through the energy storage core 201, thereby improving the convenience of using the wall-mounted micro-wastewater energy-saving commercial RO reverse osmosis water supply equipment. After the concentrated water precipitated by the RO micro-wastewater membrane 5 to treat the raw water is discharged, the concentrated water that can be reused can be reintroduced into the RO micro-wastewater membrane 5 through the action of the reflux proportional valve 8 and the six-chamber booster pump 9, while the concentrated water that cannot be reused is directly discharged through the wastewater pipe 14, thereby further improving the energy-saving performance of the wall-mounted micro-wastewater energy-saving commercial RO reverse osmosis water supply equipment.
