[0054] A reverse osmosis water treatment process comprises the following steps:

[0056] S2: The water after preliminary filtration is sent to the reverse osmosis water treatment device, and the reverse osmosis membrane 22 filters the sewage. The filtered sewage passes through the reverse osmosis membrane 22 from outside to inside and enters the outlet pipe 21, and is finally discharged to the outside through the outlet pipe 21.

The movable plate 26 reciprocates to squeeze the expansion and contraction cavity 29, and the cleaning liquid in the expansion and contraction cavity 29 is reciprocated to squeeze into the gap of the reverse osmosis membrane 22, thereby accelerating the removal of cutting debris.

[0059] The working steps of the present invention are:

[0060] The device is started. There is a start button on the electric control cabinet 11. Press the start button to start the booster pump 16. The high-pressure water passes through the primary filter 12, the secondary filter 13, and the reverse osmosis filter 14 in sequence. The primary filter 12 performs preliminary filtration on the water, and the secondary filter 13 performs secondary filtration on the water. After the filtration of the primary filter 12 and the secondary filter 13, large particles of impurities in the water are removed. The water mixed with small particles of impurities passes through the reverse osmosis filter 14. The physical filtration principle of the semi-permeable membrane is used to separate the water quality. The wastewater is discharged through the wastewater pipe 25, and the filtered water is discharged through the outlet pipe 21.

[0061] The flow process of wastewater in the filter cylinder 18 is as follows: the wastewater passes through the water inlet pipe 24, the first hole 33, the outer ring cavity 31, the second hole 34, and the third hole 35 in sequence into the annular gap 68, and the wastewater passes through the reverse osmosis membrane 22. The filtered clean water is collected into the outlet pipe 21 through the openings on the wall of the outlet pipe 21.

[0062] It should be noted that the device includes two water flow paths, one of which is a wastewater filtration path: high-pressure wastewater passes through the water inlet pipe 24, the first hole 33, the outer ring cavity 31, the second hole 34, and the third hole 35 in sequence into the annular gap 68, and the wastewater passes through the reverse osmosis membrane 22. The filtered clean water is collected into the water outlet pipe 21 through the opening on the wall of the water outlet pipe 21 and discharged outward through 21. This path is the clean water discharge path;

[0063] The second is the wastewater discharge path: high-pressure wastewater enters the gap of the reverse osmosis membrane 22 , and the remaining wastewater flows downward under the action of the pressure difference and is finally discharged through the wastewater pipe 25 .

[0064] Start the cleaning process, rotate the rotating tube 61 so that the first through hole 62 and the second through hole 63 are aligned and connected, and the cleaning pump pumps the cleaning liquid into the rotating tube 61. The electric control cabinet 11 has a cleaning button. Press the cleaning button, and the driving motor drives the driving gear 60 and the driving sleeve 39 to rotate, and drives the rotating toothed disc 37 and the shielding disc 30 to rotate. The shielding disc 30 drives the cutting line 42 to rotate. The cutting line 42 itself is guided by the first spiral guide groove 45 to move in a spiral trajectory. The cutting line 42 moves in the gap of the reverse osmosis membrane 22 to separate the bonded reverse osmosis membrane 22, and the reverse osmosis membrane 22 is layered to form a gap for the cleaning liquid to pass through;

[0065] The cleaning liquid mixed with impurities enters the wastewater chamber 50, and the centrifugal motor drives the filter cylinder 18 to rotate through the belt transmission mechanism. The water inside the wastewater chamber 50 is centrifuged and flows to the outer annular gap 68 to play a role in chip removal.
