Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an ultrafiltration membrane component. Background Art

[0002] Ultrafiltration membranes are used as artificial permeable membranes in the ultrafiltration process. They are generally made from polymer materials such as cellulose acetate, cellulose acetate esters, polyethylene, polysulfone, and polyamide. They are typically prefabricated into various types of membrane modules, including tubular, plate-type, spiral, and capillary modules. Multiple modules are then assembled together to increase the filtration area and facilitate maintenance.

[0003] After long-term use, the ultrafiltration membrane assembly is prone to bacterial growth. Therefore, when purifying water, the filtered water should be further sterilized to ensure water safety. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an ultrafiltration membrane assembly, which can further sterilize the water after ultrafiltration to prevent the growth of bacteria.

[0005] To this end, the technical solution of the present invention is: an ultrafiltration membrane assembly, comprising a membrane shell, an end cover and an ultrafiltration membrane group, the end cover is fixedly connected to the membrane shell, the ultrafiltration membrane group comprises a central tube, an ultrafiltration membrane wire and an ultrafiltration membrane cover, the three are fixed by sealing glue, the end of the central tube is a water inlet, extending out of the end of the membrane shell; the end cover is provided with a water outlet column, the water outlet column is connected to the water outlet hole inside the ultrafiltration membrane wire; the side of the water outlet column is provided with an installation interface, an electrolytic sterilization component is provided at the installation interface, and positive and negative electrode sheets are provided at one end of the electrolytic sterilization component, and the positive and negative electrode sheets extend into the water outlet column.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the other end of the electrolytic sterilization component is also provided with a positive wire post and a negative wire post, which are located outside the water outlet column, and the positive wire post and the negative wire post are connected to the electronic control unit through wires.

[0007] On the basis of the above solution and as a preferred solution of the above solution: a plurality of water inlet holes are provided on the central tube, and a water inlet channel is formed inside the central tube.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the outer side of the ultrafiltration membrane cover is tightly fitted with the inner wall of the end cover, and the end face of the ultrafiltration membrane cover is provided with a water outlet hole for the ultrafiltration membrane wire, which is connected to the water outlet column to form a water outlet channel.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a flushing port is provided on the side of the end cover, the flushing port is located on the inner side of the ultrafiltration membrane cover, and is connected to the membrane shell to form a flushing channel.

[0010] The raw water enters the ultrafiltration membrane group from the central tube. There are outward-scattering water inlet holes around the front section of the central tube of the ultrafiltration membrane. The raw water flows to the ultrafiltration membrane filaments through the water inlet holes. The clean water is filtered by the ultrafiltration membrane filaments and converges to the water outlet column on the ultrafiltration membrane cover. At the same time, the electrolytic sterilization component is inserted into the water outlet column in a quick-connect manner. When working, it produces a certain concentration of negative hydrogen ions, negative oxygen ions, ozone and other sterilization gases, which can effectively sterilize the water outlet column, prevent the growth of bacteria, and ensure water safety.

[0011] During flushing, the water outlet is closed, and the raw water rushes toward the membrane fibers through the water inlet hole of the central tube of the ultrafiltration membrane. Since the water outlet is cut off, the raw water flushes the membrane fibers from the inside to the outside, and the waste water after flushing flows out through the flushing port.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. An electrolytic sterilization component is set on the side of the water outlet column to use negative hydrogen ions, negative oxygen ions, ozone and other gases generated by electrolysis to sterilize and ensure drinking water safety.

[0014] 2. Using central water inlet, the membrane fibers can be thoroughly flushed from the inside out, removing dirt on the surface of the ultrafiltration membrane fibers, preventing the membrane fibers from being blocked, and extending the service life of the membrane fibers.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Therefore, the terms "first" and "second" may explicitly or implicitly refer to one or more of these features. In the description of this utility model, "several" and "a number" mean two or more, unless otherwise specifically defined.

[0023] See the accompanying drawings. The ultrafiltration membrane assembly described in this embodiment includes a membrane housing 1, an end cap 2, and an ultrafiltration membrane group 3. The end cap 2 is fixedly connected to the membrane housing 1. The ultrafiltration membrane group 3 includes a central tube 31, ultrafiltration membrane filaments 32, and an ultrafiltration membrane cap 33, all of which are secured by a sealing adhesive. The end of the central tube 31 is a water inlet 311, which extends from the middle of one end of the membrane housing 1 for connecting to water. The central tube 31 is provided with a plurality of water inlet holes 312, forming a water inlet channel inside the central tube 31.

[0024] The outer side of the ultrafiltration membrane cover 33 fits tightly with the inner wall of the end cover 2, and the end face of the ultrafiltration membrane cover 33 is provided with a water outlet hole for the ultrafiltration membrane wire 32. The end cover 2 is provided with a water outlet column 21, which is connected to the water outlet hole inside the ultrafiltration membrane wire to form a water outlet channel.

[0025] The water outlet column 21 has a mounting interface 22 on its side, where an electrolytic sterilization assembly 4 is located. Positive and negative electrode sheets 41 are located at one end of the assembly, extending into the water outlet column 21. A positive lead 42 and a negative lead 43 are located at the other end of the assembly, located outside the water outlet column. These lead 42 and negative lead 43 are connected to the electronic control unit via wires. The positive and negative electrode sheets 41 are inserted into the pipeline and, when energized, generate an electrolytic reaction with the water flowing within the pipeline.

[0026] A flushing port 23 is provided on the side of the end cover 2. The flushing port 23 is located on the inner side of the ultrafiltration membrane cover 33 and is connected to the membrane shell 1 to form a flushing channel. That is to say, the ultrafiltration membrane cover 33 blocks the flushing channel and the water outlet channel, and flushing and water outlet are unrelated to each other.

[0027] During use, raw water enters the ultrafiltration membrane group 3 from the central tube 31. There are outward-scattering water inlet holes 312 around the front section of the ultrafiltration membrane central tube 31. The raw water flows to the ultrafiltration membrane filaments 32 through the water inlet holes 312. The clean water is filtered by the ultrafiltration membrane filaments 32 and then converges on the ultrafiltration membrane cover 33 and flows into the water outlet column 21. At the same time, the electrolytic sterilization component 4 is inserted into the water outlet column 21 in a quick-connect manner. When working, it produces a certain concentration of negative hydrogen ions, negative oxygen ions, ozone and other sterilizing gases, which can effectively sterilize the water outlet column, prevent the growth of bacteria, and ensure water safety.

[0028] During flushing, the water outlet is closed, and the raw water rushes toward the membrane fibers through the water inlet 312 of the ultrafiltration membrane central tube 31. Since the water outlet is cut off, the raw water flushes the membrane fibers from the inside to the outside, and the waste water after flushing flows out through the flushing port.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
