Material receiving mechanism, reverse osmosis membrane production equipment and material receiving method

Abstract

The invention relates to a receiving mechanism, reverse osmosis membrane production equipment and a receiving method. The receiving mechanism is used for receiving a first membrane and a second membrane in coil replacement, and comprises a clamping device; and the clamping device clamps the first membrane and the second membrane to keep the first membrane and the second membrane in a tension state. The invention further provides the receiving method; the receiving method adopts the receiving mechanism to receive materials; and the receiving method comprises the following steps: (S1) free ends of the first membrane and the second membrane are tailored; and (S2) the clamping device clamps the free ends of the first membrane and the second membrane to keep the first membrane and the second membrane in the tension state for receiving the materials. The invention further provides the reverse osmosis membrane production equipment adopting the receiving mechanism. The receiving mechanism, the reverse osmosis membrane production equipment and the receiving method, provided by the invention, have the advantages of positioning of the membranes in the tension state after material receiving and balanced tension distribution on the membranes.

Description

【Technical field】 [0001] The invention relates to a material receiving mechanism, reverse osmosis membrane production equipment adopting the material receiving mechanism, and a material receiving method. 【Background technique】 [0002] In membrane separation technology, the types of membranes are often divided into microfiltration membranes, ultrafiltration membranes, ultrathin filtration membranes, nanofiltration membranes, and reverse osmosis membranes. Among them, reverse osmosis membranes have the highest filtration accuracy, which can reach 50-150 molecular cut-offs. Rate. [0003] The production process of reverse osmosis membrane will have a splicing station, the function of splicing is to join the old roll and the new roll when the old roll is about to run out. However, the existing splicing mechanisms all have the problem that the spliced ​​film is in a relaxed state and the tension distribution on the film is unbalanced. Therefore, how to solve the problem that t...
