Description

Technical Field

[0001] This invention belongs to the field of separation membrane preparation technology, and in particular relates to an ultrafiltration membrane module containing capsaicin derivatives. Background Technology

[0002] The traditional hollow fiber curtain membrane manufacturing process involves pre-cutting the membrane fibers into bundles of a certain length, binding them with cable ties, hanging one end up, plugging the other end with latex, placing it into a casting tank, and then filling it with end-sealing glue.

[0003] Existing hollow fiber membrane preparation mainly uses vinylidene fluoride, polysulfone, polyethersulfone, polyethylene, etc. as raw materials. However, the membrane module is immersed in the biological reactor for a long time, and the root of the hollow fiber membrane filaments is seriously contaminated. Once sludge settles, it is difficult to remove. This reduces the effective filtration area and filtration uniformity of the membrane module. There are leaks in the membrane shell and membrane filament encapsulation. Over time, sludge settles and hardens, and sludge continues to deposit upwards along the root of the membrane filaments, resulting in high turbidity of the produced water. Utility Model Content

[0004] The purpose of this invention is to provide an ultrafiltration membrane module containing capsaicin derivatives, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an ultrafiltration membrane module containing capsaicin derivatives, comprising an outer shell, with connectors at the top and bottom of the outer shell, and an inlet pipe and an outlet pipe respectively penetrating and fixedly connected to the sides of the two sets of connectors, with a sealing gasket fixedly connected to the adjacent ends of the two sets of connectors; an inner filter membrane, a middle filter membrane, and an outer filter membrane are disposed inside the outer shell, each of the inner filter membrane, middle filter membrane, and outer filter membrane comprising a membrane shell and membrane fibers; and a quick-assembly / disassembly assembly is disposed inside the connectors.

[0007] Furthermore, the membrane filaments are evenly distributed at equal intervals along the interior of the membrane shell.

[0008] Furthermore, the membrane filaments are equipped with reinforced internal support, and the membrane shell contains a copolymer containing capsaicin derivatives. The hollow fiber membrane filaments are equipped with reinforced internal support, and the membrane shell is modified with a copolymer containing capsaicin derivatives, so that the membrane filaments have good anti-fouling and mechanical properties.

[0009] Furthermore, the quick-release assembly includes a compression spring, a groove, and an annular groove. The top of the compression spring is fixedly connected to the inner top of the connector. The groove is formed on the inner sidewall of the connector. A telescopic spring is provided inside the groove. An arc-shaped block is slidably connected inside the groove through the telescopic spring. A pull rod is fixedly connected to one end of the arc-shaped block near the telescopic spring. The annular groove is formed on the surface of the outer housing.

[0010] Furthermore, the end of the compression spring furthest from the connector is initially in contact with the outer housing, and the compression spring is initially compressed. When the compression spring rebounds, it will cause the connector to separate from the outer housing.

[0011] Furthermore, in the initial state, half of the arc-shaped block is located within the annular groove, and the longitudinal length of the annular groove is equal to the longitudinal length of the groove. When the arc-shaped block is stuck in the annular groove, the connector cannot be separated from the outer shell.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses reinforced internal support for the membrane fibers and modifies the membrane shell with a copolymer containing capsaicin derivatives to construct a stable antibacterial functional layer on the hollow fiber membrane, giving the membrane high antifouling properties. At the same time, it further improves the mechanical properties of the membrane. The roughness of the contact surface between the membrane shell and the membrane fibers is increased, the membrane shell depth is increased, and modified epoxy resin is used for encapsulation, so that the membrane fibers and membrane shell are encapsulated without leakage points, are not easy to fall off, and the turbidity of the produced water is stable and low.

[0014] 2. This utility model is equipped with a quick-release assembly, so that when it is necessary to remove the connectors at both ends of the outer shell, pulling the pull rods on both sides will cause the compression spring to rebound and separate the connectors from the outer shell. When reinstalling, the connectors are combined with the outer shell, and the cooperation of the arc block and the ring groove makes it impossible for the connectors to separate from the outer shell, which facilitates disassembly and assembly.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model is an ultrafiltration membrane module containing capsaicin derivatives, including an outer shell 1. The top and bottom of the outer shell 1 are provided with connectors 2. The sides of the two sets of connectors 2 are respectively connected to an inlet pipe 3 and an outlet pipe 4. The ends of the two sets of connectors 2 that are close to each other are fixedly connected with sealing gaskets 5. The outer shell 1 is provided with an inner filter membrane 6, a middle filter membrane 7 and an outer filter membrane 8. The inner filter membrane 6, the middle filter membrane 7 and the outer filter membrane 8 all include a membrane shell 91 and a membrane fiber 92. The connectors 2 are provided with a quick disassembly and assembly assembly 10.

[0026] Membrane filaments 92 are evenly distributed at equal intervals along the interior of membrane shell 91.

[0027] The membrane fiber 92 adopts an overall reinforced internal support, and the membrane fiber 92 contains a copolymer containing capsaicin derivatives. The hollow fiber membrane fiber 92 adopts an reinforced internal support, and the membrane fiber 92 is modified with a copolymer containing capsaicin derivatives, so that the membrane fiber 92 has good anti-fouling and mechanical properties.

[0028] The quick-release assembly 10 includes a compression spring 101, a groove 102, and an annular groove 106. The top of the compression spring 101 is fixedly connected to the inner top of the connector 2. The groove 102 is formed on the inner side wall of the connector 2. A telescopic spring 103 is provided inside the groove 102. An arc-shaped block 104 is slidably connected inside the groove 102 through the telescopic spring 103. A pull rod 105 is fixedly connected to one end of the arc-shaped block 104 near the telescopic spring 103. The annular groove 106 is formed on the surface of the outer housing 1.

[0029] The end of the compression spring 101 away from the connector 2 is initially in contact with the outer housing 1, and the compression spring 101 is initially in a compressed state. When the compression spring 101 rebounds, it will cause the connector 2 to separate from the outer housing 1.

[0030] In the initial state, half of the arc-shaped block 104 is located in the annular groove 106, and the longitudinal length of the annular groove 106 is equal to the longitudinal length of the groove 102. When the arc-shaped block 104 is stuck in the annular groove 106, the connector 2 cannot be separated from the outer shell 1.

[0031] A specific application of this embodiment is as follows: Water enters the outer shell 1 through the inlet pipe 3 and is directly located inside the inner filter membrane 6. The middle filter membrane 7 of the inner filter membrane 6 and the bottom of the outer filter membrane 8 are in a closed state. The water will be filtered through the inner filter membrane 6, the middle filter membrane 7, and the outer filter membrane 8 and then discharged to the outside of the outer filter membrane 8, and finally discharged through the outlet pipe 4 at the bottom of the outer shell 1. Because the inner membrane filaments 92 of the inner filter membrane 6, the middle filter membrane 7, and the outer filter membrane 8 adopt an enhanced internal support and are modified with a copolymer containing capsaicin derivatives, a stable antibacterial functional layer is constructed on the hollow fiber membrane filaments 92, giving the membrane high antifouling properties. At the same time, the mechanical properties of the membrane are further improved by increasing the roughness of the contact surface between the membrane shell 91 and the membrane filaments 92, increasing the depth of the membrane shell 91, and using modified epoxy. Resin encapsulation ensures that the membrane filaments 92 and membrane housing 91 are sealed without leaks, preventing them from easily detaching and resulting in stable and low turbidity of the produced water. When it is necessary to remove the connectors 2 at both ends of the outer housing 1, pull the pull rods 105 on both sides of the connector 2, causing the arc-shaped block 104 to leave the annular groove 106 and retract into the groove 102. At this time, the compression spring 101 will rebound, causing the connector 2 to separate from the outer housing 1. When it is necessary to reinstall, the connector 2 and the outer housing 1 are merged. Initially, the arc surface of the arc block 104 is squeezed and retracts into the groove 102, and the telescopic spring 103 is compressed. When the groove 102 coincides with the annular groove 106, the telescopic spring 103 rebounds, causing the arc block 104 to be locked into the annular groove 106, making it impossible for the connector 2 to separate from the outer housing 1, thus completing the installation. The installation and disassembly are simple and convenient for later maintenance.
