Under natural conditions, water molecules migrate from the side with low solute concentration to the side with high solute concentration through a semipermeable membrane. In the reverse osmosis process, by applying pressure to the side with high solute concentration, water molecules are forced to pass through the semipermeable membrane in reverse, flowing from the high concentration side to the low concentration side, while filtering out dissolved solids and impurities.

[0013] A water treatment method of a high-salt wastewater treatment device based on an RO membrane comprises the following steps:

[0014] S1: First, the staff placed the RO membrane between two clamps and started a small motor to drive the adjacent sheaves to rotate. The sheave on the right can drive the sheave on the left to rotate through a belt. When the sheave on the left rotates, it can drive the rotating plate to rotate.

Through the linkage rod, it enters the inner cavity of the RO membrane and contacts the filter element inside the RO membrane. When the elevator moves upward, the sealing ring can be disassembled and the filter element can be taken out. The filter element can be cleaned by a cleaning machine.

[0019] 1.

[0036] A water treatment method of a high-salt wastewater treatment device based on an RO membrane comprises the following steps:

[0037] S1: First, the staff places the RO membrane 8 between the two clamping blocks 22, and starts the small motor 29 to drive the adjacent groove wheels 28 to rotate. The groove wheel 28 on the right side can drive the groove wheel 28 on the left side to rotate through the belt 27. When the groove wheel 28 on the left side rotates, it can drive the rotating plate 23 to rotate. When the rotating plate 23 rotates, it can drive the two cranks 30 to rotate in opposite directions. When the two cranks 30 rotate in opposite directions, they can drive the two clamping blocks 22 to move in opposite directions, so as to clamp the RO membrane 8;

[0038] S2: When the RO membrane 8 is clamped, the motor 7 can be started to drive the swing plate to rotate. When the swing plate rotates, the RO membrane 8 can be driven to contact the top of the bearing plate 31. When the RO membrane 8 contacts the top of the bearing plate 31, the dryer 9 can be started to dry the RO membrane 8. When the RO membrane 8 is dried, if the weight of the RO membrane 8 is greater than the weight of the conventional RO membrane 8, the bearing plate 31 can be driven to move downward and contact the trigger 38, and the water inside the RO membrane 8 enters the inner cavity of the collection box 34 through the discharge pipe 37;

[0039] S3: When the RO membrane 8 is inspected, the cylinder 5 can be started to drive the fixing plate 6 to move upward, so that the RO membrane 8 is separated from the top of the placement plate 10, and the RO membrane 8 is driven to flip to the bottom of the top plate 11, and then the elevator 12 drives the disassembly mechanism to move downward and contact the sealing ring on the top of the RO membrane 8;

[0040] S4: When the lifting motor is started, the lifting plate 14 can be driven to move upward. When the lifting plate 14 moves upward, the flip plate 18 can drive several hinged plates 17 to move in opposite directions, thereby driving the clamping plate 16 to move in opposite directions and fix it to the outside of the sealing ring. It enters the inner cavity of the RO membrane 8 through the linkage rod 15 and contacts the filter element inside the RO membrane 8. When the elevator 12 moves upward, the sealing ring can be disassembled and the filter element can be taken out. The filter element can be cleaned by the cleaning machine 3. When the trigger 38 is triggered, it means that the current filter element is highly contaminated, so the cleaning liquid spraying mechanism is started to spray the cleaning liquid on the outside of the filter element to improve the cleaning effect.

[0041] Working principle: First, the staff places the RO membrane 8 between the two clamping blocks 22, and starts the small motor 29 to drive the adjacent groove wheel 28 to rotate. The groove wheel 28 on the right side can drive the groove wheel 28 on the left side to rotate through the belt 27. When the groove wheel 28 on the left side rotates, it can drive the rotating plate 23 to rotate. When the rotating plate 23 rotates, it can drive the two cranks 30 to rotate in opposite directions. When the two cranks 30 rotate in opposite directions, they can drive the two clamping blocks 22 to move in opposite directions, so as to clamp the RO membrane 8. When the RO membrane 8 is clamped, the motor 7 can be started to drive the swing plate to rotate. When the swing plate rotates, it can drive the RO membrane 8 to contact the top of the bearing plate 31. When the RO membrane 8 contacts the top of the bearing plate 31, the dryer 9 can be started to dry the RO membrane 8. When the RO membrane 8 is dried, if the weight of the RO membrane 8 is greater than the weight of the conventional RO membrane 8, it can drive the bearing plate 31 to move downward and contact the trigger 38, and the water inside the RO membrane 8 is discharged through the drain The material pipe 37 enters the inner cavity of the collection box 34. When the detection of the RO membrane 8 is completed, the cylinder 5 can be started to drive the fixing plate 6 to move upward, so that the RO membrane 8 is separated from the top of the placement plate 10, and the RO membrane 8 is driven to flip to the bottom of the top plate 11. Then the lifter 12 drives the disassembly mechanism to move downward and contact with the sealing ring on the top of the RO membrane 8. When the lifting motor is started, the lifting plate 14 can be driven to move upward. When the lifting plate 14 moves upward, the flip plate 18 can drive a number of hinged plates 17 to move in the opposite direction, thereby driving the clamping plate 16 to move in the opposite direction and fix it with the outside of the sealing ring. Through the linkage rod 15, it enters the inner cavity of the RO membrane 8 and contacts with the filter element inside the RO membrane 8. When the lifter 12 moves upward, the sealing ring can be disassembled and the filter element can be taken out. The filter element can be cleaned by the cleaning machine 3. When the trigger 38 is triggered, it means that the current filter element is highly contaminated, so the cleaning liquid spraying mechanism is started to spray the cleaning liquid on the outside of the filter element to improve the cleaning effect.

The top of the positioning plate (21) is provided with a lifting motor, and the power output shaft of the lifting motor is fixedly connected with the lifting plate (14). The outer side of the positioning plate (21) is fixedly connected with an L-shaped welding rod, and the other end of the L-shaped welding rod is fixedly connected with the top plate (11).

9. The water treatment method of a high-salt wastewater treatment device based on an RO membrane according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: First, the staff places the RO membrane (8) between the two clamping blocks (22), and starts the small motor (29) to drive the adjacent groove wheels (28) to rotate. The groove wheel (28) on the right side can drive the groove wheel (28) on the left side to rotate through the belt (27). When the groove wheel (28) on the left side rotates, it can drive the rotating plate (23) to rotate. When the rotating plate (23) rotates, it can drive the two cranks (30) to rotate in opposite directions. When the two cranks (30) rotate in opposite directions, they can drive the two clamping blocks (22) to move in opposite directions, thereby clamping the RO membrane (8); S2: When the RO membrane (8) is clamped, the motor (7) can be started to drive the swing plate to rotate. When the swing plate rotates, the RO membrane (8) can be driven to contact the top of the bearing plate (31). When the RO membrane (8) contacts the top of the bearing plate (31), the dryer (9) can be started to dry the RO membrane (8). When the RO membrane (8) is dried, if the weight of the RO membrane (8) is greater than the weight of a conventional RO membrane (8), the bearing plate (31) can be driven to move downward and contact the trigger (38), and the water inside the RO membrane (8) enters the inner cavity of the collection box (34) through the discharge pipe (37); S3: When the RO membrane (8) is tested, the cylinder (5) can be activated to drive the fixing plate (6) to move upward, thereby separating the RO membrane (8) from the top of the placement plate (10), and driving the RO membrane (8) to flip to the bottom of the top plate (11), and then the elevator (12) drives the disassembly mechanism to move downward and contact the sealing ring on the top of the RO membrane (8); S4: When the lifting motor is started, the lifting plate (14) can be driven to move upward. When the lifting plate (14) moves upward, the flip plate (18) can drive the plurality of hinged plates (17) to move in the opposite direction, thereby driving the clamping plate (16) to move in the opposite direction, and fix the outer side of the sealing ring. The linkage rod 15 enters the inner cavity of the RO membrane (8) and contacts the filter element inside the RO membrane (8). When the lifter (12) moves upward, the sealing ring can be disassembled and the filter element can be taken out. The filter element can be cleaned by the cleaning machine (3). When the trigger (38) is triggered, it means that the current filter element is highly contaminated, so the cleaning liquid spraying mechanism is started to spray the cleaning liquid on the outer side of the filter element to improve the cleaning effect.
