[0027] Therefore, the inventor provides an efficient pure water device, including a primary filtration system, a chemical dosing system, a secondary purification device 1, a reverse osmosis filtration system, and a pure water tank 2.

After the filter element of the filter is cleaned and replaced, it operates normally.

At this time, the raw water is filtered through the filter b4, and the filter element of the filter a3 can be cleaned and replaced. After the filter a3 is cleaned, the valve a14 is opened and the valve b15 remains closed. At this time, the raw water is filtered through the filter a3, and the filter element of the filter b4 can be cleaned and replaced. After the filter a3 and the filter b4 are cleaned, the valves a14 and b15 are both opened to restore the normal working state.

[0043] Among them, the primary filtered water is mixed with the chemical in the cylinder section and then spirally enters the cone barrel section downward, and most of the precipitates are separated out in the cone barrel section. The precipitates are discharged from the lower part of the separation tank under the action of gravity and centrifugal force.

[0044] Furthermore, the inlet height of the outlet connecting pipe above the mixing and separation tank 8 inside the tank is lower than the height of the side inlet;

[0048] In summary, the device includes a primary filtration system, a chemical dosing system, a secondary purification device 1, a reverse osmosis filtration system, and a pure water tank 2. The primary filtration system can ensure the normal production during the replacement and cleaning of the filter through the control pipeline; through the power provided by water pump a7, the filtered water is mixed and separated in the mixing and separation tank 8 without additional power, reducing the production cost; the pressurized reverse osmosis filtration technology is adopted to reduce energy consumption and improve the quality of the produced pure water.

[0049] The working principle of the present utility model:

[0050] Raw water enters the water supply pipeline 6 from the raw water pipeline 16. First, it passes through the primary filtration system to filter out some insoluble impurities and gases, and then is discharged into the water tank a5 after filtration; under normal working conditions, the valve a14 is opened, the valve b15 is opened, the valve c18 is closed, and the valve d20 is closed. At this time, the raw water passes through the filter a3 and the filter b4 in sequence and then is discharged into the water tank a5;

[0051] When the filters are in a clean state, the valve a14 is closed, the valve b15 is closed, the valve c18 is opened, and the valve d20 is closed. The raw water is filtered by the filter b4 and then discharged into the water tank a5 through the bypass pipeline a17. At this time, the filter element of the filter a3 can be cleaned and replaced. After the filter a3 is cleaned, the valve a14 is opened, the valve b15 remains closed, the valve c18 is closed, and the valve d20 is opened. The raw water is filtered by the filter a3 and then discharged into the water tank a5 through the bypass pipeline b19. At this time, the filter element of the filter b4 can be cleaned and replaced. After the filter a3 and the filter b4 are cleaned, both the valve a14 and the valve b15 are opened to restore the normal working state. This structure ensures the normal progress of production when replacing and cleaning the filters through the control pipeline, and guarantees the production efficiency;

[0052] The water after primary filtration enters the water tank a5. The water tank a5 plays a role in storing and stabilizing the water pressure, providing a stable working condition for the mixing and separation tank 8. The water pump a7 pumps the primary filtered water in the water tank a5 into the mixing and separation tank 8. Since the pumped water has an initial velocity and is pumped in from the side, the primary filtered water rotates along the cylindrical wall of the mixing and filtration tank after being pumped in. The medicament is input through the dosing port 21. The medicament and the primary filtered water are mixed and reacted in the upper part of the cylinder, generating precipitation. Due to the action of gravity and centrifugal force, the precipitation begins to accumulate at the conical part in the lower part of the mixing and separation tank 8, and the upper layer is the solution with less precipitation. The solution with less precipitation is discharged from the upper outlet and enters the secondary purification device 1. The impurities with more precipitation are discharged into the sedimentation tank 9 through the lower outlet for sedimentation. After a period of sedimentation, the solution in the sedimentation tank 9 is stratified, and the upper layer is the solution with less impurities. At this time, the valve e23 is opened and the water pump b10 is started to pump out the upper layer of the solution, which enters the secondary purification device 1 through the bypass pipeline c22. This device uses the power provided by the water pump a7 to mix and separate the filtered water in the mixing and separation tank 8 without additional power, reducing the production cost;

[0053] After being purified in the secondary purification device 1, the secondary purified water is discharged into the water tank b11. The water tank b11 can play a role in storing and stabilizing the pressure. The booster pump pressurizes the water in the water tank b11 and then discharges it into the reverse osmosis filtration tank 13. After pressurization, the filtration efficiency is improved, and the filtered water is discharged into the pure water tank 2. Compared with the distillation purification method, the energy consumption is reduced and the output quality is improved;

[0054] So far, the treatment process of the raw water by this device is completed.
