Description

Technical Field

[0001] This utility model relates to the field of tubular aerator technology, specifically to a tubular aerator membrane. Background Technology

[0002] Currently, tubular aerators are widely used in wastewater treatment and sewage treatment, mainly to inject air or oxygen into water bodies to increase the dissolved oxygen content and promote the biodegradation of organic matter.

[0003] Existing membrane materials used in tubular aerators are mostly made of a single material. As the usage time increases, the membrane is prone to problems such as aging, wear, contamination, and scaling, which leads to uneven gas distribution or reduced flow rate, thus affecting the aeration effect.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a tubular aerator membrane.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a tubular aerator membrane, comprising a membrane disposed on the aeration port of a pipe, the membrane comprising an inner layer, a bearing layer, an outer layer and a protective layer arranged sequentially from the inside to the outside, the membrane having a hollow structure and an elliptical cylindrical structure with openings at both the front and the back, and the opposite edges on both sides of the membrane having a U-shaped structure.

[0007] The installation and removal mechanism is fixedly installed at the end of the aeration port of the pipeline and detachably assembled with the membrane, for convenient installation and removal of the membrane.

[0008] Furthermore, two mounting slots are symmetrically arranged on both sides of one end of the membrane corresponding to the aeration port of the pipeline. The installation and removal mechanism includes an end block fixedly arranged at the end of the aeration port of the pipeline and a support ring arranged at the inner end of the end block. The support ring is symmetrically arranged on both sides for engaging in the mounting slots. An outer support ring is arranged on the outer side of the support ring and is slidably arranged at the end of the end block.

[0009] Furthermore, the limiting unit includes a spring disposed inside the support ring and a first wedge block disposed at the end of the spring and adapted to be connected to the mounting slot, the first wedge block vertically penetrating through the upper surface of the support ring.

[0010] Furthermore, a second wedge is adapted to be disposed on the inclined surface of the first wedge. The second wedge is fixedly disposed on the inner surface of the outer support ring. Moving the outer support ring causes the second wedge to move. Through the force of the inclined contact between the second wedge and the first wedge, the first wedge is forced to move along the elastic deformation direction of the spring, so that the first wedge separates from the inner groove of the mounting slot.

[0011] Furthermore, the membrane is uniformly provided with circular pores for generating microbubbles.

[0012] Furthermore, a limiting ring is provided on the movable end of the corresponding end block on the outer support ring, and a sliding groove is adapted to be provided on the outside of the limiting ring and inside the end block.

[0013] Compared with existing technologies, this utility model has the following beneficial effects: The membrane skin, comprising an inner layer, a load-bearing layer, an outer layer, and a protective layer arranged sequentially from the inside out, ensures the membrane skin's effectiveness in various application scenarios through the supporting function of the inner layer, the strength support of the load-bearing layer, the wear resistance of the outer layer, and the antibacterial protection of the protective layer. The complementary functions of each layer enable the membrane skin to exhibit excellent performance in actual use. Furthermore, the included installation and removal mechanism allows for convenient installation and removal of the membrane skin at the pipeline aeration port, enabling easy replacement or cleaning of the membrane skin, thus extending its service life and simplifying maintenance.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1-4 As shown, the present invention discloses a tubular aerator membrane, including a membrane 200 disposed on the aeration port 100 of the pipeline. The membrane 200 includes an inner layer 1, a bearing layer 2, an outer layer 3, and a protective layer 4 arranged sequentially from the inside to the outside. The membrane 200 has a hollow structure and an elliptical cylinder structure with openings at both the front and the back. The opposite edges on both sides of the membrane 200 are U-shaped.

[0022] The installation and removal mechanism 5 is fixedly installed at the end of the aeration port 100 of the pipeline and detachably assembled with the membrane 200, for convenient installation and removal of the membrane 200.

[0023] In specific implementation, the inner layer 1, the bearing layer 2, the outer layer 3, and the protective layer 4 are assembled in an integral molding process from the inside out. Through the supporting function of the inner layer 1, the strength support of the bearing layer 2, the wear resistance of the outer layer 3, and the antibacterial protection of the protective layer 4, the effectiveness of the membrane 200 in various application scenarios is guaranteed. Moreover, the complementary functions of each layer enable the membrane 200 to exhibit excellent performance in actual use.

[0024] The installation and removal mechanism 5 installed at the end of the pipeline aeration port 100 can easily install and remove the membrane 200 at the pipeline aeration port 100, and can replace or clean the membrane 200 at any time, which helps to extend the service life of the membrane 200.

[0025] It should be noted that the opposite edges of the membrane 200 are processed into a U-shaped structure, which makes it less prone to creases and bursts during aeration. Compared with the L-shaped structure of ordinary aeration hoses, it has a longer service life.

[0026] It should be noted that the inner layer 1 is made of polyvinyl chloride, polytetrafluoroethylene, silicone, etc. It serves a supporting function and provides a flow path for gas through its pores. Gas enters the outer layer 3 from the inner layer 1, forming bubbles on the surface of the membrane 200 for oxygen transfer.

[0027] The supporting layer 2 is made of polyester, etc. It serves to enhance the strength of the membrane 200, prevent the membrane 200 from being damaged by external forces (such as compression, tension, etc.), and ensure the stability and durability of the membrane 200 under high water pressure, air pressure and long-term use.

[0028] The outer layer 3 is made of materials such as polyurethane, silicone rubber, and polytetrafluoroethylene, which have high wear resistance, aging resistance, and strong corrosion resistance. It can withstand long-term water flow impact and mechanical friction;

[0029] Protective layer 4 uses silver ions and titanium alloy coatings. It can effectively inhibit the adhesion of bacteria, algae and other organisms, prevent scaling or contamination on the membrane 200 surface, and thus maintain the high efficiency performance of the aerator.

[0030] In one embodiment, two mounting slots 6 are symmetrically arranged on both sides of one end of the membrane 200 corresponding to the aeration port 100 of the pipeline. The installation and removal mechanism 5 includes an end block 51 fixedly disposed at the end of the aeration port 100 of the pipeline and a support ring 52 disposed at the inner end of the end block 51. The support ring 52 is symmetrically provided with limiting units 53 for engaging in the mounting slots 6 on both sides. An outer support ring 54 is disposed on the outer side of the support ring 52 and is slidably disposed at the end of the end block 51.

[0031] The limiting unit 53 includes a spring 531 disposed inside the support ring 52 and a first wedge block 532 disposed at the end of the spring 531 and adapted to the mounting slot 6. The first wedge block 532 vertically penetrates the upper surface of the support ring 52. With this design, by welding and connecting the end block 51 to the aeration outlet end of the pipe aeration port 100, and the support ring 52 welded to the corresponding end of the membrane 200 on the end block 51, when the membrane 200 moves along the outer surface of the support ring 52 towards the end block 51, the membrane 200 will contact and be pressed against the first wedge block 532 formed on the limiting unit 53. Under the elastic compression of the spring 531 welded to the first wedge block 532, the first wedge block 532 engages and is fixed with the mounting slot 6, thus achieving the connection between the membrane 200 and the installation / removal mechanism 5.

[0032] It should be noted that the spring 531 is installed on the inner side of the support ring 52 by welding, and the first wedge block 532 is welded on the spring 531. Also, the initial position of the vertex of the first wedge block 532 will pass through the support ring 52 and be placed on the outer side of the support ring 52.

[0033] It should be noted that the angle between the horizontal plane where the upper inclined surface of the first wedge block 532 is located and the horizontal plane where the installation insertion direction of the diaphragm 200 is located is an acute angle, which makes it easier for the diaphragm 200 to compress the first wedge block 532 connected to the spring 531 during insertion installation.

[0034] In one embodiment, the inclined surface of the first wedge block 532 is adapted to contact a second wedge block 55. The second wedge block 55 is fixedly disposed on the inner surface of the outer support ring 54. Moving the outer support ring 54 causes the second wedge block 55 to move. Through the force of the inclined contact between the second wedge block 55 and the first wedge block 532, the first wedge block 532 is forced to move along the elastic deformation direction of the spring 531, so that the first wedge block 532 separates from the inner groove of the mounting slot 6. With this design, the second wedge block 55, welded to the position corresponding to the first wedge block 532 inside the outer support ring 54, will drive the second wedge block 55 when the outer support ring 54 moves horizontally outward along the horizontal surface outside the diaphragm 200. Through the oblique contact force between the second wedge block 55 and the first wedge block 532, the first wedge block 532 is forced to move along the elastic deformation direction of the spring 531, so that the first wedge block 532 is separated from the inner groove of the mounting slot 6, thus realizing the disassembly of the diaphragm 200 at the end of the end block 51.

[0035] In one embodiment, the membrane 200 is uniformly provided with circular pores 7 for generating microbubbles. This design, with the circular pores 7 evenly grooved on the membrane 200, allows the generated microbubbles to enter the water, increasing the dissolved oxygen content and effectively ensuring the stability of bubble generation, thereby guaranteeing a good aeration effect.

[0036] In one embodiment, a limiting ring 541 is provided on the movable end of the outer support ring 54 corresponding to the end block 51. A groove 56 is adapted to be provided on the outside of the limiting ring 541 and inside the end block 51. With this design, by welding the limiting ring 541 onto the outer support ring 54, during the disassembly operation of the membrane 200 by moving the outer support ring 54, the inner cavity of the groove 56 provided in the end block 51 provides the outer support ring 54 with a movable space, avoiding separation of the outer support ring 54 from the end block 51, and allowing the outer support ring 54 to move and be limited within a limited range.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0038] It should be noted that if the embodiments of this utility model involve directional indicators, such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, "several" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
