Description

Technical Field

[0001] This invention relates to the field of water purification technology, and in particular to an automatic sterilization and water purification system. Background Technology

[0002] Existing water purifiers mainly use a multi-stage filter system, typically consisting of a tap water inlet, a PP cotton filter, an activated carbon filter, an RO membrane filter, and a faucet. The PP cotton filter, activated carbon filter, RO membrane filter, and faucet are connected in sequence, filtering impurities, heavy metals, microorganisms, and other substances from the water step by step. However, during filtration, microorganisms and impurities can also adhere to or be adsorbed onto or inside the filter element. Under suitable conditions, this can lead to bacterial growth, which can clog the membrane, reduce filtration performance, and cause secondary pollution of the effluent. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic sterilization and water purification system.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: An automatic sterilization and water purification system, characterized in that it includes an inlet filter element, a booster pump, a reverse osmosis membrane, a water storage pressure tank, and an ultraviolet sterilization module. The inlet filter element comprises a first PP cotton filter element, a first carbon rod filter element, and a second PP cotton filter element arranged sequentially along the water flow direction. Water enters through the inlet end of the first PP cotton filter element, and the outlet of the second PP cotton filter element is connected to the inlet end of the booster pump via a pipeline. The pipeline at the filter element outlet is sequentially equipped with a low-pressure switch and a first solenoid valve along the water flow direction. The output end of the booster pump is connected to the lower part of the reverse osmosis membrane and the water storage pressure tank via pipelines. The pipeline at the inlet of the reverse osmosis membrane is equipped with a second solenoid valve. The pipeline between the booster pump and the water storage pressure tank is equipped with a third solenoid valve and a high-pressure switch along the water delivery direction. The reverse osmosis membrane has a wastewater outlet and a pure water outlet. The pure water outlet is connected to the pipeline between the third solenoid valve and the high-pressure switch via a bypass pipeline. The upper part of the water storage pressure tank is connected to the input end of the ultraviolet sterilization module via a pipeline. The pipeline at the input end of the ultraviolet sterilization module is equipped with an outlet TDS probe. The output end of the ultraviolet sterilization module outputs pure water through an output pipeline. The output end of the ultraviolet sterilization module is connected to the input end of the booster pump via a return pipeline. The return pipeline is equipped with a fourth solenoid valve.

[0005] Furthermore, a second carbon rod filter element is provided in the pipeline between the water storage pressure tank and the ultraviolet sterilization module.

[0006] Furthermore, the bypass pipeline is equipped with a first check valve, which connects the pipeline from the pure water outlet to the third solenoid valve and the high-pressure switch.

[0007] Furthermore, the reflux pipeline is equipped with a second one-way valve, which connects the UV sterilization module to the booster pump.

[0008] This invention can complete water production and internal sterilization. The source water enters from the inlet and passes through the filter element, reverse osmosis membrane container and ultraviolet sterilization module to remove particulate matter and residual chlorine. The water is then output through two channels: pure water and concentrated wastewater. After sterilization by the ultraviolet sterilization module, hygienic and safe pure water is supplied. When the system enters the sterilization state, the water output from the ultraviolet sterilization module returns to the booster pump through the return pipe to continue the sterilization process, causing the bacterial concentration in the pure water to continuously decrease until it approaches zero. This effectively inhibits bacterial colonization on the inner surface of the pipeline, especially the inner surface of the water storage pressure tank, ensuring that the pure water supplied by the system remains hygienic and safe during long-term operation.

[0011] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] This invention discloses an automatic sterilization and water purification system, such as... Figure 1 As shown, it includes an inlet filter element, a booster pump 6, a reverse osmosis membrane 9, a water storage pressure tank 12, and an ultraviolet sterilization module 15. Water enters through the inlet filter element, which includes a first PP cotton filter element 1, a first carbon rod filter element 2, and a second PP cotton filter element 3 arranged sequentially along the water conveyance direction. The outlet of the second PP cotton filter element 3 is connected to the inlet of the booster pump 6 through a pipeline. The pipeline at the filter element outlet is provided with a low-pressure switch 4 and a first solenoid valve 5 arranged sequentially along the water conveyance direction.

[0013] The output end of the booster pump 6 is connected to the lower part of the reverse osmosis membrane 9 and the water storage pressure tank 12 through pipelines. The pipeline at the inlet of the reverse osmosis membrane 9 is equipped with a second solenoid valve 7. The pipeline between the booster pump 6 and the water storage pressure tank 12 is equipped with a third solenoid valve 8 and a high-pressure switch 11 in sequence along the water conveyance direction. The reverse osmosis membrane 9 is equipped with a wastewater outlet and a pure water outlet. The pure water outlet is connected to the pipeline between the third solenoid valve 8 and the high-pressure switch 11 through a bypass pipeline. The bypass pipeline is equipped with a first check valve 10. The first check valve 10 connects the pure water outlet to the pipeline between the third solenoid valve 8 and the high-pressure switch 11.

[0014] The upper part of the water storage pressure tank 12 is connected to the input end of the ultraviolet sterilization module 15 through a pipeline. The pipeline between the water storage pressure tank 12 and the ultraviolet sterilization module 15 is equipped with a second carbon rod filter element 13. The pipeline at the input end of the ultraviolet sterilization module 15 is equipped with an outlet water TDS probe 14. The output end of the ultraviolet sterilization module 15 outputs pure water to the outside through an output pipeline. The output end of the ultraviolet sterilization module 15 is connected to the input end of the booster pump 6 through a return pipeline. The return pipeline is equipped with a fourth solenoid valve 16 and a second one-way valve 17. The second one-way valve 17 connects the ultraviolet sterilization module 15 to the booster pump 6.

[0015] like Figure 1 As shown, the working principle of the automatic sterilization and water purification system is as follows: Water production working principle When the system starts producing water, the source water enters from the inlet and passes through three filters: the first PP cotton filter element 1, the first carbon rod filter element 2, and the second PP cotton filter element 3. These filters remove particulate matter and residual chlorine impurities from the water. The low-pressure switch 4 sensor ensures that the water pressure of the source water meets the standard, preventing the system from running dry.

[0016] At this time, the first solenoid valve 5 is opened, the booster pump 6 is in working condition, the second solenoid valve 7 is opened, and pressurized water enters the reverse osmosis membrane 9. Under the action of the reverse osmosis membrane 9, the pressurized water is output in two pipelines: pure water and concentrated wastewater. The wastewater is discharged through the wastewater pipeline.

[0017] The purified water passes through the first one-way valve 10 of the bypass pipeline. A water pressure control signal is provided by the high-pressure switch 11, which causes the system to stop water production after the purified water is full. The purified water passes through the second carbon rod filter 13 to improve the taste. The TDS probe 14 sensor reads the TDS value of the purified water. After being sterilized by the ultraviolet sterilization module 15, hygienic and safe purified water is supplied.

[0018] Internal automatic sterilization principle When the system enters the sterilization state, the first solenoid valve 5 and the second solenoid valve 7 are closed, the booster pump 6 is started, and the third solenoid valve 8 and the fourth solenoid valve 16 are opened. Water enters the water storage pressure tank 12 from the output end of the booster pump 6 through the third solenoid valve 8, and then passes through the second carbon rod filter and the ultraviolet sterilization module 15. Bacteria in the water are effectively removed. The water then flows back through the return pipeline through the fourth solenoid valve 16 and the second check valve 17, returning to the input end of the booster pump 6.

[0019] Repeat the above circulating sterilization process to continuously reduce the bacterial concentration in the purified water until it approaches zero.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
