Abstract
Description
Technical Field
[0001] The utility model relates to the field of water purification, in particular to a novel split type ultrafiltration membrane component. Background Art
[0002] Ultrafiltration is a membrane separation technology that can purify and separate solutions. The ultrafiltration membrane system is a solution separation device that uses ultrafiltration membrane filaments as the filtration medium and the pressure difference on both sides of the membrane as the driving force. The ultrafiltration membrane only allows the solvent in the solution, such as water molecules, inorganic salts and small molecular organic matter, to pass through, while intercepting macromolecular substances such as suspended matter, colloids, proteins and microorganisms in the solution. It can completely filter out harmful substances such as bacteria, rust, colloids, etc. in the water, and retain trace elements and minerals in the water that are beneficial to the human body, thereby achieving the purpose of purification and separation.
[0003] In traditional membrane structures, the membrane column is bonded to the shell through packaging materials, which has no effect during normal use. However, in scenarios with high requirements for hygiene conditions such as food, beverages, and medicine, it is generally necessary to frequently steam sterilize the membrane components and pipelines. Due to the different shrinkage and expansion coefficients of the membrane column and the shell, it is very easy to cause the shell and the membrane column to separate at the bonding point, causing leakage and damage. At this time, the general form of ultrafiltration membrane structure is difficult to withstand long-term and frequent high-temperature steam and cannot meet the needs. In addition, since the membrane column is bonded to the shell, the membrane column cannot be removed for replacement alone, and all components can only be replaced, causing great economic losses and environmental pollution. For this reason, we provide a new split ultrafiltration membrane component. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a novel split ultrafiltration membrane assembly to solve the problems raised in the above background technology.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a new type of split ultrafiltration membrane assembly, including an end cover, a shell, a split membrane column, a sealing ring and a limiting ring; the shell is a cylindrical structure with an opening at one end, and a liquid inlet pipe is provided in the middle of the other end; the end cover is screwed on the open end of the shell; a split membrane column coaxial with the shell is fitted inside, one end of the split membrane column is provided with an annular groove, and the sealing ring is provided on the annular groove; the split membrane column and the shell are elastically sealed and connected via the sealing ring; a sewage pipe is provided on the shell near the lower side of the annular groove of the split membrane column; the limiting ring is provided on the upper side of one end of the split membrane column with the annular groove, and a plurality of holes are provided on the side wall of the limiting ring; a liquid outlet pipe is provided at a position corresponding to the side wall of the shell and the limiting ring.
[0006] Furthermore, the diameter of the hole on the side wall of the limiting ring is smaller than the diameter of the liquid outlet pipe.
[0007] Furthermore, the split membrane column is provided with an internal thread for cooperating with a plug-in connector to facilitate taking out the membrane column for replacement.
[0008] Furthermore, a dustproof gasket is provided between the end cover and the limiting ring.
[0009] Furthermore, the material used for the end cover, the shell and the limiting ring is stainless steel.
[0010] Furthermore, a handle is provided on the end cover.

[0018] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings, rather than all structures.
[0019] Example:
[0020] like Figure 1 and Figure 3 As shown, a novel split ultrafiltration membrane assembly comprises an end cap 1, a housing 2, a split membrane column 3, a sealing ring 4 and a limiting ring 5; the housing 2 is a cylindrical structure with an opening at one end, and a liquid inlet pipe 6 is provided in the middle of the other end; the end cap 1 is screwed on the open end of the housing 2; a split membrane column 3 coaxial with the housing 2 is attached inside the housing 2, an annular groove is provided at one end of the split membrane column 3, and the sealing ring 4 is provided on the annular groove; the split membrane column 3 and the housing 2 are elastically sealed and connected through the sealing ring 4; a sewage pipe 7 is provided on the housing 2 near the lower side of the annular groove of the split membrane column 3; the limiting ring 5 is provided on the upper side of one end of the split membrane column 3 provided with the annular groove, and a plurality of holes are provided on the side wall of the limiting ring 5; a liquid outlet pipe 8 is provided on the side wall of the housing 2 corresponding to the limiting ring 5. A handle 10 is provided on the end cap 1.
[0021] like Figure 3 As shown, the diameter of the hole on the side wall of the limiting ring 5 is smaller than the diameter of the liquid outlet pipe 8 to ensure that the treated liquid can flow out of the liquid outlet pipe smoothly. A dustproof gasket is arranged between the end cover 2 and the limiting ring 5; the materials used for the end cover 1, the shell 2 and the limiting ring 5 are stainless steel. The setting of the limiting ring 5 plays a limiting role on the split membrane column 3 and the end cover 1, and at the same time, with the use of the dustproof gasket, it prevents external dust from falling into the end cover 1.
[0022] In this embodiment, the housing 2 is made of stainless steel metal, which can withstand long-term and frequent high-temperature steam sterilization without damaging its structure; the split membrane column 3 and the housing 2 are elastically sealed by a sealing ring 4. The size difference caused by the different material expansion coefficients in high and low temperature environments is offset by the elastic sealing ring 4, thereby ensuring the airtightness of the structure. The limit ring 5 and the end cover 1 behind the split membrane column 3 are also made of stainless steel metal materials, with a sealing ring 4 at the connection and a limit ring 5 at the fixed position, and the service life is extremely long.
[0023] like Figure 4 As shown, the split membrane column 3 is provided with an internal thread 9. After the split membrane column 3 material is aged or damaged, Figure 5 The connector shown in the figure removes the limit ring 5, and the stud of the connector cooperates with the internal thread 9 on the split membrane column 3 to realize the disassembly between the split membrane column 3 and the shell 2. It does not affect the production progress, but also reduces the cost of overall replacement and avoids the pollution of the environment by waste membrane components.
[0024] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
