Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to a novel reverse osmosis component. Background Technology

[0002] In the field of reverse osmosis water purification equipment, the reverse osmosis module is the core unit, and its structural design directly affects the water purification efficiency, maintenance convenience, and sealing performance. Traditional reverse osmosis modules often use a shell and filter element sleeve structure. When the filter element needs to be replaced or cleaned, the sealing ring of the traditional reverse osmosis module is in close contact with the inner wall of the shell throughout the entire process. Due to the high friction between the sealing ring and the shell, the filter element needs to overcome the resistance throughout the process when it is removed. A large pushing force is required during operation, which not only consumes manpower but also easily damages the filter element, sealing ring, or shell structure due to improper force, resulting in low maintenance efficiency and increased equipment operation and maintenance costs and time. Utility Model Content

[0003] The purpose of this invention is to provide a novel reverse osmosis component that is easy to disassemble.

[0004] The purpose of this utility model is achieved as follows: a novel reverse osmosis component includes an outer shell and a reverse osmosis filter element placed inside the outer shell; the reverse osmosis filter element is composed of a filter element shell, a reverse osmosis membrane assembly, and a central tube from the outside to the inside;

[0005] The outer shell is a cylindrical structure with openings at both ends. The openings at both ends of the outer shell have annular protruding steps. The outer surfaces at both ends of the outer shell have external threads. The two ends of the outer shell are respectively connected to an inlet cap and an outlet cap via threads. A filter cylinder is provided between the inlet cap and the reverse osmosis filter element.

[0006] The reverse osmosis membrane assembly has a receiving cavity with one open end at its center. A central tube is installed in the receiving cavity, and multiple sets of through holes are evenly distributed on the central tube. A baffle is provided on the outer periphery of the filter element shell near the end. A finger-shaped sealing ring is provided on the outer periphery of the filter element shell inside the baffle and on the outer periphery of the filter element shell at the other end. The sealing ring abuts against the inner diameter surface of the protruding step.

[0007] Preferably, the filter cartridge consists of an outer cylinder and multiple layers of filter screens built into the outer cylinder. The diameter of the outer cylinder is larger than the diameter of the filter element shell and smaller than the inner diameter of the raised step. One end of the inner side of the outer cylinder abuts against the baffle, and the other end is pressed by the water inlet end cap.

[0008] Preferably, a sealing gasket is provided between one end of the inner side of the outer cylinder and the stop block.

[0009] Preferably, the sealing ring slides without contacting the inner diameter surface of the outer shell between the raised steps at both ends.

[0010] Preferably, the inner side of the water outlet cap is provided with an annular groove, and the end of the filter element shell near the water outlet cap is embedded in the annular groove to form a limiting fit.

[0011] Preferably, the inner side of the water inlet cap is provided with an annular groove that is embedded and fitted into one end of the outer side of the outer cylinder.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] When the sealing ring slides, it does not come into contact with the inner wall of the housing between the raised steps at both ends. Pushing the filter element a short distance can make the sealing ring disengage from the steps. Compared with the traditional structure where the sealing ring is in contact with the cylinder the whole time and requires a lot of pulling, it greatly reduces the resistance to disassembly and assembly, making it easier to disassemble, clean or replace the filter element, shortening the operation and maintenance time and improving maintenance efficiency.

[0019] like Figure 1 As shown, a novel reverse osmosis component includes an outer shell 1 and a reverse osmosis filter element 2 placed inside the outer shell 1; the reverse osmosis filter element 2 is composed of a filter element shell 201, a reverse osmosis membrane assembly 202, and a central tube 203 from the outside to the inside.

[0020] The outer shell 1 is a cylindrical structure with openings at both ends. The openings at both ends of the outer shell 1 are provided with annular protruding steps 101. The outer surfaces at both ends of the outer shell 1 are provided with external threads. The two ends of the outer shell 1 are respectively connected to the inlet end cap 3 and the outlet end cap 4 by threads. A filter cylinder 5 is provided between the inlet end cap 3 and the reverse osmosis filter element 2.

[0021] The reverse osmosis membrane assembly 202 has a receiving cavity 2021 with one end open at its center. A central tube 203 is installed in the receiving cavity 2021. Multiple sets of through holes are evenly distributed on the central tube 203. A baffle 2011 is provided near the end of the filter element housing 201. A finger-shaped sealing ring 6 is provided on the filter element housing 201 inside the baffle 2011 and on the outer periphery of the filter element housing 201 at the other end. The sealing ring 6 abuts against the inner diameter surface of the protruding step 101.

[0022] The filter cartridge 5 consists of an outer cylinder 501 and a multi-layer filter screen 502 built into the outer cylinder 501. The diameter of the outer cylinder 501 is larger than the diameter of the filter element shell 201 and smaller than the inner diameter of the raised step 101. One end of the inner side of the outer cylinder 501 abuts against the baffle 2011, and the other end is pressed by the water inlet end cap 3. The filter cartridge adopts a pressing connection method, which is more efficient during disassembly and installation.

[0023] A sealing gasket 7 is provided between one end of the inner side of the outer cylinder 501 and the stop block 2011. The sealing gasket and the stop block form the first seal, and the finger-shaped rubber and the raised step form the subsequent second seal, which greatly improves the overall sealing performance.

[0024] The sealing ring 6 slides without contacting the inner diameter surface of the outer shell between the raised steps 101 at both ends; when pushing out the internal filter element, only a short push is needed to disengage the finger rubber from the raised steps, without the need to use a large pushing force throughout the process, which is convenient and quick.

[0025] The inner side of the water outlet end cap 4 is provided with an annular groove 8. The filter element housing 201 is embedded in the annular groove at one end near the water outlet end cap 4 to form a limiting fit. One end of the filter element housing is limited by the water outlet end cap, and the other end is limited by the filter cylinder, thereby ensuring the stability of the filter element housing after it is inserted into the housing.

[0026] The inner side of the water inlet end cap 3 is provided with an annular groove 8 that fits into one end of the outer cylinder, ensuring the stability of the overall structure after the filter cartridge is installed and preventing it from shaking too much.

[0027] The working principle of this utility model is explained as follows: The water to be treated enters the device through the inlet cap and first flows into the filter cartridge. After preliminary filtration through multiple layers of filter cartridges, larger particles of impurities are removed. After filtration, the water flows to the area between the filter cartridge shell and the outer shell. Under pressure, the water molecules pass through the reverse osmosis membrane assembly and enter the receiving cavity of the membrane assembly. They then flow into the central tube through the through hole on the central tube. Finally, the purified water flows from the opening end of the central tube to the outlet cap, completing the reverse osmosis water purification process. When replacing the internal filter cartridge, it is only necessary to push the filter cartridge a short distance to move the sealing ring away from the step, which facilitates the disassembly, cleaning, or replacement of the filter cartridge.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
