A supporting seat 5 is arranged to slide in the height direction of the rack 1 on the sliding seat 4, and the supporting seat 5 is movably arranged between the end cover 3 and the shell cylinder 2.
[0036] When the reverse osmosis membrane needs to be replaced, the pneumatic clamp jaw 31 clamps the reverse osmosis membrane that has been cleaned. The end cover 3 is opened by sliding in the width direction of the rack 1, and the reverse osmosis membrane that has been cleaned is taken out. At the same time, the supporting seat 5 is raised by sliding in the height direction of the rack 1, and the supporting seat 5 is close to the reverse osmosis membrane that has been cleaned. The pneumatic clamp jaw 31 is loosened, and the reverse osmosis membrane that has been cleaned is placed on the supporting seat 5. Then, the sliding seat 4 is slid in the length direction of the rack 1, so that the reverse osmosis membrane to be cleaned is aligned with the pneumatic clamp jaw 31. The pneumatic clamp jaw 31 clamps the reverse osmosis membrane to be cleaned, and then the supporting seat 5 lowers the reverse osmosis membrane that has been cleaned. Finally, the end cover 3 is driven to slide towards the shell cylinder 2, so that the reverse osmosis membrane to be cleaned is inserted into the cylinder from the placing opening 21, and the end cover 3 seals the shell cylinder 2. The reverse osmosis membrane is cleaned in the shell cylinder 2.
[0037] In order to facilitate the sliding of the end cover 3, the sliding seat 4 and the supporting seat 5, refer to Figure 1 A first air cylinder 11 is fixedly arranged on the rack 1, and the output end of the first air cylinder 11 is fixedly connected with the end cover 3, and is used to drive the end cover 3 to move close to or away from the shell cylinder 2.
