Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of seawater desalination devices, and in particular relates to a seawater desalination reverse osmosis membrane element pushing device. Background Art
[0002] Reverse osmosis membrane elements are needed in the double-membrane seawater desalination production process. When in use, the reverse osmosis membrane elements are installed in a special membrane shell. There are 7 reverse osmosis membrane elements in one membrane shell. The inner diameter of the membrane shell is small and the length is large. Due to being in the seawater environment for a long time, salt will precipitate on the outer surface of the membrane element, and it will stick to the inner surface of the membrane shell. Each time the membrane element contamination is checked and the membrane element is replaced, the membrane element must be manually pushed out of the membrane shell. If adhesion occurs, personnel need to push or hit it hard to loosen the membrane element. The height of large-scale seawater desalination units is generally about 7 to 10 meters, and the membrane elements are mostly at high places. If the thrust or impact force is not well controlled, it is easy to damage the membrane element and cause personal injury. Utility Model Content
