Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reverse osmosis devices, in particular to a reverse osmosis device with a cleaning water tank. Background Art
[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation process that uses a pressure differential as a driving force to separate a solvent from a solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent permeates in the opposite direction of its natural osmotic flow. The resulting permeate, or permeate, is obtained on the low-pressure side of the membrane, while a concentrated solution, or concentrate, is obtained on the high-pressure side.
[0003] During the use of reverse osmosis membranes, various pollutants such as particulate matter, organic matter, inorganic salts, etc. will gradually accumulate. These pollutants will continue to deposit on the membrane surface and in the membrane pores, resulting in increased membrane pollution, thereby increasing the cleaning frequency and cleaning costs. Membrane pollution may also cause other failures, such as increased pump pressure, pipe blockage, etc., increasing the system failure rate and maintenance costs. In response to the above problems, a reverse osmosis device with a cleaning water tank is proposed to solve them. Utility Model Content

The pipe support 7 firmly supports the U-shaped tube 8 to ensure that it will not shake due to the impact of water flow during operation, thereby improving the stability and reliability of the entire device. The design of the U-shaped tube 8 helps to smoothly transition the water flow, reduce turbulence and eddies, and reduce the impact on the inner wall of the pipe. The right side of the upper end of the U-shaped tube 8 is fixedly connected to the Venturi tube 15, and a filter assembly 16 is fixedly installed on the upper end of the Venturi tube 15.
[0021] Specifically, the filter assembly 16 includes a filter box 1601, a liquid outlet pipe 1603 is fixedly connected to the left side of the bottom of the filter box 1601, the bottom end of the liquid outlet pipe 1603 is fixedly connected to the upper end of the venturi tube 15, and the upper right end of the filter box 1601 is fixedly connected to the liquid inlet pipe 1602.
[0022] Specifically, a first filter plate 1604 is fixedly connected to one side of the filter box 1601 near the liquid inlet pipe 1602, a second filter plate 1605 is fixedly connected to the left side of the first filter plate 1604 inside the filter box 1601, and a third filter plate 1606 is fixedly connected to the left side of the second filter plate 1605 inside the filter box 1601. The first filter plate 1604, the second filter plate 1605, and the third filter plate 1606 in the filter assembly 16 can preliminarily filter out large particles of impurities in the water, reduce the burden on the subsequent reverse osmosis filter 9, and extend its service life.
[0023] Specifically, a filling pipe 12 is fixedly connected to the middle of the second guide pipe 10. The design of the filling pipe 12 allows the filtered pure water to be easily returned to the cleaning tank 3 for storage for later use.

[0026] Specifically, the upper surface of the base plate 1 and the right side of the cleaning box 3 are fixedly connected to the distribution box 20, which centrally controls the power supply of the entire device, facilitates operation and maintenance, and improves the safety of the equipment.
[0027] Working principle: During normal reverse osmosis filtration, the liquid inlet pipe 1602 is first connected to the external water pipe, the external water source is preliminarily filtered through the filter assembly 16, and then accelerated by the venturi tube 15 through the U-shaped tube 8 to enter the reverse osmosis filter 9 for filtration. The filtered pure water can be discharged to the outside through the second guide pipe 10 for collection, or the first valve 11 can be closed and the second valve 14 can be opened to allow the pure water to enter the cleaning tank 3 through the filling pipe 12 for storage. When it is necessary to flush the pipeline, close the first valve 11 and the second valve 14, and the cleaning pump 5 draws out the pure water inside the cleaning tank 3 through the first guide pipe 4, passes through the cleaning pipe 6 and then enters the second guide pipe 10 to flow in reverse order into the reverse osmosis filter 9, U-shaped tube 8, venturi tube 15 and filter assembly 16 to flush the filtered pipeline.
