Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a pure water waterway structure with a single-stage and double-stage reverse osmosis switching function. Background Technique

[0002] In the medical system, the specification requirements for medical water far exceed those of ordinary water use environments. In order to avoid pollution, in the existing medical system, tap water is generally treated twice. The first is pretreatment, which mainly filters tap water. The second treatment is to perform reverse osmosis treatment on the filtered purified water to make it pure water. In order to meet diverse usage requirements, a pure water generation system that can switch between single-stage and double-stage reverse osmosis is proposed. Content of the Utility Model

[0003] In view of the above problems, a pure water waterway structure with a single-stage and double-stage reverse osmosis switching function is provided, aiming to solve the problems existing in the prior art.

[0004] The specific technical solutions are as follows:

[0005] A pure water waterway structure with a single-stage and double-stage reverse osmosis switching function includes a first-stage reverse osmosis assembly, a second-stage reverse osmosis assembly, and a pure water output assembly. The input end of the first-stage reverse osmosis assembly is connected to an external water supply end. The output end of the first-stage reverse osmosis assembly is connected to the input end of the second-stage reverse osmosis assembly. The output end of the second-stage reverse osmosis assembly is connected to the input end of the pure water output assembly. The second-stage reverse osmosis assembly has an adjustment function to supply water to the pure water output assembly through the first-stage reverse osmosis assembly or supply water to the pure water output assembly jointly through the first-stage reverse osmosis assembly and the second-stage reverse osmosis assembly.

[0006] The above-mentioned pure water waterway structure with a single-stage and double-stage reverse osmosis switching function further has the following characteristics. The first-stage reverse osmosis assembly includes a water supply pump, a water purification part, a high-pressure pump, a first reverse osmosis device, and a first waste water regulating valve. The input end of the water supply pump is connected to an external water supply end. The output end of the water supply pump is connected to the input end of the high-pressure pump after passing through the water purification part. The output end of the high-pressure pump is connected to the input end of the first reverse osmosis device. The output end of the first reverse osmosis device is connected to the input end of the second-stage reverse osmosis assembly. The waste water end of the first reverse osmosis device is provided with the first waste water regulating valve.

[0007] The beneficial effect of the above solution: Tap water is pressurized by a water supply pump and becomes purified water after passing through the water purification part. The purified water becomes first-stage pure water after being pressurized by the high-pressure pump and passing through the first reverse osmosis device.

[0008] The above-mentioned pure water waterway structure with single-stage and double-stage reverse osmosis switching functions also has the following characteristics. The water purification unit includes a quartz sand filter, an activated carbon filter, and a softening resin tank. The quartz sand filter, the activated carbon filter, and the softening resin tank are connected in sequence to filter the tap water input by the water supply pump.

[0009] Beneficial effects of the above solution: The tap water passes through the quartz sand filter, the activated carbon filter, and the softening resin tank in sequence for multi-stage filtration, converting the tap water into purified water.

[0010] The above-mentioned pure water waterway structure with single-stage and double-stage reverse osmosis switching functions also has the following characteristics. The secondary reverse osmosis assembly includes a manual regulating valve, a diaphragm pump, a second reverse osmosis device, and a second wastewater regulating valve. The output end of the first reverse osmosis device is connected to the input end of the pure water output assembly after passing through the diaphragm pump and the second reverse osmosis device in sequence. The output end of the first reverse osmosis device is also connected to the input end of the pure water output assembly through the manual regulating valve. When the manual regulating valve is opened, the pure water output by the primary reverse osmosis assembly directly enters the pure water output assembly. When the manual regulating valve is closed, the pure water output by the primary reverse osmosis assembly will enter the pure water output assembly after passing through the secondary reverse osmosis assembly. The wastewater end of the second reverse osmosis device is provided with the second wastewater regulating valve.

[0011] Beneficial effects of the above solution: According to the opening or closing of the manual regulating valve, it is controlled whether the primary pure water directly enters the pure water output assembly or enters the pure water output assembly after passing through the secondary reverse osmosis assembly.

[0012] The above-mentioned pure water waterway structure with single-stage and double-stage reverse osmosis switching functions also has the following characteristics. The secondary reverse osmosis assembly further includes a flow switch, and the flow switch is arranged at the input end of the diaphragm pump.

[0013] Beneficial effects of the above solution: The operation of the diaphragm pump is controlled by the flow switch. When the flow switch detects insufficient flow, the flow switch cuts off the power supply of the diaphragm pump to avoid its idling damage.

[0014] The above-mentioned pure water waterway structure with single-stage and double-stage reverse osmosis switching functions also has the following characteristics. The wastewater end of the second reverse osmosis device is connected to the input end of the high-pressure pump through the second wastewater regulating valve.

[0015] Beneficial effects of the above solution: The purity of the wastewater output by the second reverse osmosis device exceeds that of the purified water. Therefore, guiding it back to the high-pressure pump of the primary reverse osmosis assembly for re-reverse osmosis treatment can effectively avoid wasting water resources.

[0016] The above-mentioned pure water waterway structure with single-stage and double-stage reverse osmosis switching function also has the following characteristics. The pure water output component includes a pure water tank and a booster pump. The output end of the second-stage reverse osmosis component is connected to the input end of the pure water tank, and the output end of the pure water tank outputs pure water through the booster pump.

[0017] Beneficial effects of the above solution: According to the requirements of the medical system, primary pure water or secondary pure water can be input into the pure water tank, and finally the pure water is output by using the booster pump.

[0018] In summary, the beneficial effects of this solution are:

[0019] In the pure water waterway structure with single-stage and double-stage reverse osmosis switching function provided by the present utility model, by connecting the first-stage reverse osmosis component and the second-stage reverse osmosis component in series, and the second-stage reverse osmosis component can control whether the primary pure water is directly output or processed by the second-stage reverse osmosis component to become secondary pure water, it is convenient for the medical system to adjust the purity of the pure water according to the requirements. The pure water waterway structure with single-stage and double-stage reverse osmosis switching function provided by the present utility model has the effect of being able to adjust single-stage or double-stage reverse osmosis.

When only primary pure water is required by the medical system, the manual regulating valve 9 is opened, and the primary pure water directly enters the pure water tank 13 for storage until use. When secondary pure water is required by the medical system, the manual regulating valve 9 is closed, and the diaphragm pump 11 is started.
