Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis filter membranes, in particular to a reverse osmosis filter membrane which is easy to replace. Background Art

[0002] Reverse osmosis membrane, also known as RO membrane, is the core component of reverse osmosis technology. It is an artificial semi-permeable membrane made of polymer materials. Reverse osmosis technology is a membrane separation technology that uses the pressure difference on both sides of the membrane as power to separate the solvent and solute in the solution.

[0003] After searching, the patent number is 202121939551.6, and the name is a utility model of a new type of reverse osmosis filter membrane, including an end cap A and a filter membrane body, wherein the end cap A is installed at the left end of the filter membrane body, and the right end of the filter membrane body is provided with an end cap B. The circular outer parts of the end caps A and B are both sleeved with sealing rings, and the inner parts of the centers of the end caps A and B are both provided with pipe sleeves. By improving the central tube of the reverse osmosis filter membrane, the traditional single-row porous central tube is improved into a new central tube. Compared with the traditional single-row porous central tube, the new central tube has the advantages of stronger water collection capacity and a supporting role in the center. When the treated water flows from left to right through the filter membrane body, the new central tube can collect the filtered pure water in a larger area and faster, avoiding the situation where the traditional central tube has limited water collection capacity and cannot effectively collect pure water and transport it out when a large amount of water flows through the reverse osmosis filter membrane, thereby increasing the filtration and water collection efficiency of the entire reverse osmosis filter membrane. However, there are still disadvantages to a certain extent, such as:

[0004] Water can be treated by reverse osmosis through a reverse osmosis membrane. When the reverse osmosis membrane is used for a long time, it needs to be replaced. However, the existing reverse osmosis membrane is generally an integral structure and cannot be disassembled during operation. Therefore, the reverse osmosis membrane assembly needs to be replaced as a whole, which will cause unnecessary waste of resources and is not conducive to personnel use. Utility Model Content

Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments;

[0025] Example 1:

[0026] The present application provides a replaceable reverse osmosis filter membrane comprising a central tube 1, a permeation assembly 4, and a protective shell 5. The outer surface of the central tube 1 is provided with the permeation assembly 4, the outer surface of the permeation assembly 4 is mounted with the protective shell 5, and the outer sides of the two ends of the protective shell 5 are mounted with connecting mechanisms 6. One end of the central tube 1 and the permeation assembly 4 is mounted with an end cap 1 2, and the end of the central tube 1 and the permeation assembly 4 away from the end cap 1 2 is mounted with an end cap 2 3.

[0027] The connecting mechanism 6 includes a fixing ring 601, an insert rod 602, a spring block 603 and a slot 604. The fixing rings 601 are installed on the outside of both ends of the protective shell 5, the insert rod 602 is installed on the front of the fixing ring 601, the spring block 603 is installed inside the insert rod 602, and the end cover 1 2 and the end cover 2 3 are provided with a slot 604;

[0028] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, by transporting water from the inside of end cover 1 2 to the inside of protective shell 5, the osmosis component 4 performs reverse osmosis treatment on the water, and then the treated water will be discharged from one end through the inside of the central tube 1, and the sewage treated by the osmosis component 4 will be discharged through the inside of end cover 2 3, and the connecting mechanism 6 is used to connect the protective shell 5, end cover 1 2 and end cover 2 3. The worker moves end cover 1 2 and end cover 2 3 so that the slots 604 inside end cover 1 2 and end cover 2 3 move along the outside of the insertion rod 602. When end cover 1 2 and end cover 2 3 are moved to a fixed position, the spring block 603 will move out from the inside of the insertion rod 602 under its own action. At this time, the end cover 1 2 and end cover 2 3 can be directly fixedly installed on both ends of the protective shell 5. At the same time, this method can facilitate personnel to disassemble and replace the osmosis component 4 later.

[0029] Furthermore, the osmosis assembly 4 includes a produced water collection screen 401, an isolation screen 402, and a reverse osmosis membrane 403. The outer surface of the central tube 1 is wound with the produced water collection screen 401, the outer surface of the produced water collection screen 401 is wound with the isolation screen 402, and the outer surface of the isolation screen 402 is wound with the reverse osmosis membrane 403.

[0030] Specifically, such as Figure 3As shown, in order to achieve water treatment, when water is transported to the inside of the protective shell 5, the water will be filtered and separated through the water production collection screen 401, the isolation screen 402 and the inside of the reverse osmosis membrane 403. The water production collection screen 401 is mainly used to evenly collect the desalted water passing through the reverse osmosis membrane under high pressure in the reverse osmosis system. The isolation screen 402 can provide a flow channel for the incoming water, increase the water flow rate on the surface of the reverse osmosis membrane 403, and reduce the concentration polarization phenomenon on the surface of the reverse osmosis membrane 403, thereby protecting the reverse osmosis membrane 403 from pollution and damage. The reverse osmosis membrane 403 can intercept soluble salts, colloids, microorganisms, organic matter, etc. in the water, thereby producing fresh water. The treated water will be transported to the inside of the central tube 1 and discharged from one end thereof.

[0031] Furthermore, a sealing ring 7 is installed on the outside of the fixing ring 601;

[0032] Furthermore, a sensor 701 is installed at the bottom of the inner wall of the sealing ring 7;

[0033] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the sealing of the connection between the protective shell 5, the end cover 1 2 and the end cover 2 3, the sensor 701 is a water leakage sensor, which is a prior art. When the end cover 1 2 and the end cover 2 3 are spliced ​​with the fixing ring 601 on the outside of the protective shell 5, the sealing ring 7 will be located on the outer surface of the connection between the end cover 1 2 and the end cover 2 3 and the protective shell 5. The sealing of the connection can be improved by the sealing ring 7, and the sensor 701 can detect it at the same time. When a water source is detected, it indicates that there is a leakage at the connection between the end cover 1 2 and the end cover 2 3 and the protective shell 5, which makes it easier for personnel to perform maintenance.

[0034] Furthermore, protective rings 501 are installed on the outer surface of the protective shell 5, and the protective rings 501 are distributed at equal distances;

[0035] Specifically, such as Figure 1 As shown, in order to improve the pressure resistance of the protective shell 5, protective rings 501 are equidistantly arranged on the outer surface of the protective shell 5. The protective rings 501 can improve the pressure resistance of the protective shell 5 and thus extend its service life.

[0036] Furthermore, an observation window 502 is provided on the outer surface of the protective shell 5;

[0037] Specifically, such as Figure 1 and Figure 2 As shown, in order to facilitate workers to observe the working conditions of the penetration component 4 inside the protective shell 5, the observation window 502 is made of glass. Personnel can observe the working conditions of the penetration component 4 inside the protective shell 5 through the observation window 502, so that personnel can replace it in time.

[0038] Working principle: By transporting water from the inside of the end cover 2 to the inside of the protective shell 5, the water will be filtered and separated through the water collection screen 401, the isolation screen 402 and the inside of the reverse osmosis membrane 403. The water collection screen 401 is mainly used in the reverse osmosis system to evenly collect desalted water that passes through the reverse osmosis membrane under high pressure. The isolation screen 402 can provide a flow channel for the incoming water, increase the water flow rate on the surface of the reverse osmosis membrane 403, and reduce the concentration polarization phenomenon on the surface of the reverse osmosis membrane 403. The reverse osmosis membrane 403 can intercept soluble salts, colloids, microorganisms, organic matter, etc. in the water, thereby producing fresh water and transporting it to the inside of the central tube 1 and discharged from one end thereof, and the waste water will be discharged from the inside of the end cover 2 3.

[0039] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
