With the continuous development of these fields, the demand for four-inch reverse osmosis membrane shells is also increasing.
[0004] The traditional four-inch membrane shell is made of fiberglass winding, and after lathing and drilling, the sealing plate, end plate, side nozzle, clean water outlet, block and other components are installed. The cost of the membrane shell, fiberglass shell and other components produced in this way is relatively high, and there are many production processes and low efficiency. With the increasing demand for four-inch membrane shells in the market, it is of great significance to reduce the cost of four-inch membrane shells and improve production efficiency. It can not only meet the expanding market demand, but also reduce labor, reduce costs and bring economic benefits. Utility Model Content
[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problems of high cost of fiberglass shell and other components in the prior art, more production processes and low efficiency, thereby providing a new four-inch combined membrane shell.
[0006] In order to solve the above technical problems, the utility model provides a new four-inch combined membrane housing, comprising: a membrane housing body, on which a first connection structure is provided; an end plate, arranged at one end of the membrane housing body, on which a second connection structure is provided, the first connection structure being connected to the second connection structure; a sealing plate, arranged in the membrane housing body, and on which a sealing structure is provided, a membrane element connection port, a raw concentrate water connection port, and a clean water outlet connection port are provided on the sealing plate, and the membrane element connection port is connected to the clean water outlet connection port; an adjustable gasket is arranged on the sealing plate.
[0007] Furthermore, the raw concentrated water inlet connection port and the purified water outlet connection port are located on the same side of the sealing plate.
[0008] Furthermore, the adjustable gasket is arranged on the sealing plate and has one end with a membrane element connection port.
[0009] Furthermore, the sealing structure comprises a groove and a sealing ring, wherein the groove is arranged on the outer peripheral wall of the sealing plate, and the sealing ring is arranged in the groove.
[0010] Furthermore, the sealing plate is made of plastic material.

[0013] Furthermore, the cross-section of the end plate is U-shaped.
[0014] Furthermore, the cross section of the sealing plate is in a mountain shape.
[0015] Furthermore, the first connection structure is an external thread, and the second connection structure is an internal thread.
[0016] The technical solution of this utility model has the following advantages:
[0017] The utility model provides a novel four-inch combined membrane housing, comprising: a membrane housing body, on which a first connection structure is provided; an end plate, arranged at one end of the membrane housing body, on which a second connection structure is provided, the first connection structure being connected to the second connection structure; a sealing plate, arranged in the membrane housing body, on which a sealing structure is provided, on which a membrane element connection port, a raw concentrate water connection port, and a clean water outlet connection port are provided, the membrane element connection port being connected to the clean water outlet connection port; an adjustable gasket, arranged on the sealing plate.
[0018] The connection between the membrane housing body and the end plate is achieved by arranging a first connection structure on the membrane housing body and arranging a second connection structure on the end plate; at the same time, a sealing plate is arranged in the membrane housing body, and a sealing structure is arranged on the sealing plate, that is, the sealing plate is sealed, and a membrane element connection port, a raw concentrate port connection port, and a clean water outlet connection port are arranged on the sealing plate, and the raw concentrate port and the clean water outlet can be directly connected to the sealing plate in the form of threads; the end plate is connected to the membrane housing body through a threaded structure, and the force of tightening the threads can assist in pushing the sealing plate into a specified position;
[0019] The new four-inch combined membrane shell is made by the drawing process. After being processed into the specified length according to the drawing size, a thread is machined at a certain length at the end of the outer surface. The membrane shell body made by drawing has a double-sided mold structure, so the outer surface naturally forms a smooth and flat outer surface, reducing the subsequent surface treatment and spraying processes.
[0020] The new four-inch combined membrane housing has a simple structure, eliminating traditional structures such as blocks and safety rings, while reducing a large amount of manual operations and saving raw material costs and labor costs.
[0021] At the same time, the new four-inch modular membrane housing has been personalized, with an additional adjustable gasket and a clean water outlet adapter. Since the membrane element length has a tolerance and will be compressed under working pressure, it is difficult for the membrane element to fit completely with the sealing plate during operation. By tightening the position of the adjustable gasket, the gap between the membrane element and the sealing plate can be avoided, and the membrane element can be prevented from being damaged due to string movement.
[0022] (1) The new four-inch modular membrane housing avoids the traditional dumbbell-shaped structure. The main body of the membrane housing becomes a straight-tube structure, which can adopt more and more convenient molding processes;
[0023] (2) The main body of the membrane shell is made by a drawing and winding process, which can ensure the strength in both the circumferential and axial directions. Its advantage is that it can be formed continuously, with extremely high production efficiency and without excessive manual participation;
[0024] (3) In the winding process, both the inner and outer surfaces are mold surfaces, so the produced membrane shell body can directly form a smooth and flat outer surface, reducing the processes of grinding, surface repair, spraying, etc., greatly reducing labor costs and material costs;
[0025] (4) The end plate is connected to the membrane housing body by a connecting structure, which is easy to disassemble;
[0026] (5) The sealing plate is provided with an original concentrated water inlet connection port and a clean water outlet connection port, and the clean water outlet and the original concentrated water inlet can be quickly installed on the sealing plate through threads;
[0027] (6) There is an adjustable gasket on the sealing plate, which is connected to the sealing plate by threads and the position can be adjusted to ensure that the membrane element will not move in series;
[0028] The design and development of this membrane shell structure simplifies the structure, reduces some components, and reduces material consumption. It not only improves production efficiency, but also reduces labor, greatly reducing material and labor costs; at the same time, it adds personalized design, increasing the functionality and convenience of the product.
