Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a membrane element soaking device. Background Art

[0002] Reverse osmosis membrane elements often experience performance degradation during use. Most of the performance degradation is not due to the membrane itself. After soaking the membrane element in an appropriate solution, the performance of the membrane element can be restored. When the membrane element is soaked, it cannot be completely immersed in water because of the air inside. At the same time, the unexpelled air will cause the membrane element to be soaked unevenly.

[0003] After being soaked in water, some types of membrane elements (such as type 8040) are very heavy and require a lot of effort to remove them from the barrel, which is extremely inconvenient to operate. Utility Model Content

[0017] Specifically, the telescopic mechanism and the barrel body are rotatably arranged.

[0018] Specifically, the telescopic mechanism and the barrel body are rotatably arranged via a slide rail;

[0020] The telescopic mechanism is provided with a sliding block adapted to the sliding rail, and the telescopic mechanism is rotated outside the barrel body by applying an external force to the telescopic mechanism.

[0021] Specifically, a fixedly connected limit block is provided on the slide rail near the circulating water inlet valve.

[0022] Specifically, the circulating water inlet valve and the circulating water outlet valve are arranged up and down and in the same plane.

[0023] When the utility model is used, the required solution is added into the bubble membrane cavity, the circulation cavity is connected to a constant temperature water circulation, the telescopic mechanism is lowered, and the membrane element equipped with the inner support clamp is connected to the hook; after the telescopic mechanism is raised to a suitable height, the rotary arm is rotated to rotate the membrane element above the bubble membrane cavity, the telescopic mechanism is lowered, the membrane element is placed in the bubble membrane cavity, the inner support clamp is taken out, and the telescopic mechanism raises the hook.
