[0002] Organic membranes play various important roles in the industrial and technological fields. According to their pore sizes and surface characteristics, organic membranes can be used to separate and filter different components in mixtures. This separation can be based on characteristics such as molecular size, charge, hydrophilicity and hydrophobicity, and is commonly used in water treatment, drug preparation, food processing, etc. Organic membranes can be used as part of a reactor to promote specific chemical reactions through catalysts or functional groups on their surfaces. As a packaging material, organic membranes can provide functions such as food preservation, gas barrier and microbial isolation, extending the shelf life of food and maintaining its quality. In the biomedical field, organic membranes can be used in applications such as drug release, artificial organ scaffolds, tissue engineering and biosensors. Due to the tunability of their structures and surface characteristics, organic membranes are widely used in many different industrial and technological fields and play an important role in modern life and industrial production.

[0003] The above-mentioned utility model has the following problems:

[0004] 1. The high-flux high-concentration acid-resistant organic membrane elements in the prior art are all integrated and non-detachable. As the service life extends, the holes opened inside the central tube of the reverse osmosis organic membrane will become blocked, resulting in the inability of the high-concentration acid-resistant organic membrane element to be used with high flux.

[0005] Therefore, the technical personnel in this field provide a high-flux high-concentration acid-resistant organic membrane element to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to provide a high-flux high-concentration acid-resistant organic membrane element to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution:

[0008] A high-flux high-concentration acid-resistant organic membrane element, including a reverse osmosis organic membrane main body. Both ends of the reverse osmosis organic membrane main body are provided with fixed end caps. A disassembly mechanism is arranged inside the fixed end caps. A filter central tube is fixedly connected in the middle inside the reverse osmosis organic membrane main body. Filter holes are opened on the surface of the filter central tube. A connecting tube is fixedly connected inside the fixed end cap.

[0009] As a further solution of the utility model: a clamping block groove is formed on one side of the reverse osmosis organic membrane main body close to the disassembly mechanism. The disassembly mechanism includes a clamping block, a clamping block adjustment groove, a fixing rod, a fixing rod moving groove, a spring and an adjusting member. A clamping block adjustment groove is formed on the outer side of the clamping block. One end of the clamping block adjustment groove is fixedly connected with a fixing rod. A fixing rod moving groove is formed on one side of the clamping block close to the fixing rod. A spring is sleeved on the side of the fixing rod away from the clamping block. One side of the clamping block is fixedly connected with an adjusting member.

[0010] As a further solution of the utility model: the cleaning mechanism includes a fixing cover, a rotating rod, a rotating grip, a cleaning brush and a clogging removal flexible disk. The rotating rod is rotatably connected to the inner side of the fixing cover. One side of the rotating rod is fixedly connected with a rotating grip. The other side of the rotating rod is fixedly connected with a clogging removal flexible disk. A cleaning brush is fixedly connected to the outer side of the end of the rotating rod away from the rotating grip. The disassembly mechanism is arranged on the inner side of the fixing cover.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. When the reverse osmosis organic membrane main body is used for a long time, the filter central pipe and filter holes inside the reverse osmosis organic membrane main body will be blocked. At this time, it is necessary to disassemble the fixed end caps at both ends of the reverse osmosis organic membrane main body. First, it is necessary to pull the adjusting member of the disassembly mechanism. Pull the adjusting member to move. The adjusting member drives the clamping block to move. The clamping block leaves the clamping block groove, and then the fixed end cap can be removed. At the same time, when the clamping block moves, the clamping block compresses the spring, and the fixing rod moving groove of the clamping block moves into the fixing rod. When the adjusting member is released, the spring restores its elasticity, and the spring pushes the clamping block, and the clamping block is clamped into the clamping block groove. The fixing rod and the fixing rod moving groove can guide the movement of the clamping block. Disassemble the fixed end caps at both ends, put the cleaning mechanism into the filter central pipe inside the reverse osmosis organic membrane main body, and the fixing cover clamps the fixing cover to the reverse osmosis organic membrane main body through the disassembly mechanism. Rotate the rotating grip, and the rotating grip drives the rotating rod to rotate. The rotating rod drives the cleaning brush on the outside to rotate. Use the disassembly mechanism, operate the adjusting member to move the clamping block so that it leaves the clamping block groove, so that the fixed end cap can be removed. Put the special cleaning mechanism into the filter central pipe inside the reverse osmosis organic membrane main body, use the disassembly mechanism to re-clamp the fixing cover on the reverse osmosis organic membrane main body, and drive the rotating rod to rotate through the rotating grip. The rotating rod drives the cleaning brush on the outside to rotate together to ensure a comprehensive cleaning of the filter central pipe and filter holes. When putting in and taking out the clogging removal flexible disk, the filter central pipe can be effectively unclogged to maintain the filtration efficiency and long-term performance of the reverse osmosis organic membrane.
