Description

Technical Field

[0001] This utility model relates to the field of MBR membrane module disassembly technology, and in particular to an MBR membrane module disassembly tool. Background Technology

[0002] In the MBR wastewater treatment process, the surface of the tubular MBR membrane module is prone to sludge and fibrous material buildup after long-term operation, leading to a decrease in water permeability. Therefore, it is necessary to periodically disassemble the MBR membrane module for cleaning to ensure water permeability.

[0003] The existing tubular MBR membrane module is installed vertically. Specifically, the lower end of the tubular MBR membrane module is fitted onto a pin, and the upper end is secured by two semi-circular clamping components with nuts. Disassembly requires manually loosening the nuts on the clamping components and then manually pulling the tubular MBR membrane module upwards from the pin, thus removing the MBR membrane module.

[0004] However, due to the row-mounted tubular MBR membrane modules and the narrow installation space between adjacent modules, manual disassembly of MBR membrane modules presents the following problems:

[0005] 1. Difficult to operate – the narrow spacing makes it difficult to apply force manually, resulting in low disassembly efficiency;

[0006] 2. Risk of damage – MBR membrane modules are made of PVC, and deviations in the force applied by manual pulling can easily damage the MBR membrane modules, increasing maintenance costs. Utility Model Content

[0007] The purpose of this invention is to provide an MBR membrane module disassembly tool that can easily disassemble tubular MBR membrane modules, improving disassembly efficiency while avoiding force deviation caused by manual pulling.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is: an MBR membrane module disassembly tool, including a cylindrical pry bar body, one end of the pry bar body is provided with two pry plates arranged in a "Y" shape with the pry bar body, the surfaces of the two pry plates are arranged opposite each other, and the opposite sides of the two pry plates are connected to the side wall of the pry bar body through a hinge locking assembly, and a fulcrum bolt parallel to the pry plate surface is also connected to the side wall of the pry bar body end between the two pry plates.

[0009] As a further improvement of this utility model, the hinge locking assembly includes a hinge ear plate, a hinge bolt, and a long, strip-shaped hinge member. The hinge ear plate is disposed on the side wall of the pry bar body, and the surface of the hinge ear plate is perpendicular to the surface of the pry bar. The screw end of the hinge bolt passes through the hinge ear plate and is threadedly connected to one side of the hinge member. The other side of the hinge member extends to the surface of the pry bar and is welded to the pry bar.

[0010] As a further improvement of this utility model, the hinge ear plate on one side of the hinge bolt is also provided with an arc-shaped notch arranged with the hinge bolt as the center. The arc-shaped notch is provided with a locking bolt in which the end of the screw passes through the hinge ear plate and the hinge piece in sequence and is threadedly connected to the hinge piece.

[0011] As a further improvement of this utility model, the hinge on the pry bar extends in the same direction as the pry bar, and the cross-sectional area of ​​the hinge on the pry bar gradually decreases along its extension direction.

[0012] As a further improvement of this utility model, the fulcrum bolt is set through the pry bar body, and the fulcrum bolt and the pry bar body are threadedly connected.

[0013] As a further improvement of this utility model, the outer side wall of the other end of the pry bar body is also provided with an external thread for installing an extension tube.

[0014] Beneficial effects

[0015] Compared with the prior art, the advantages of the MBR membrane module disassembly tool of this utility model are:

[0016] This tool can easily disassemble tubular MBR membrane modules. Compared to manually pulling out tubular MBR membrane modules, this device uses the lever principle, which is more convenient and less strenuous. At the same time, compared to manual pulling, the pry bar requires less space, thus avoiding the problem of low disassembly efficiency due to narrow spacing between adjacent MBR membrane modules, making it difficult to apply force manually. Its disassembly efficiency is at least five times higher than manual disassembly. In addition, compared to the force deviation caused by manual pulling, the force direction of this tool is more stable, thereby reducing the probability of damage to the MBR membrane module.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] Example:

[0028] The specific embodiments of this utility model are as follows: Figure 1-4As shown, an MBR membrane module disassembly tool includes a cylindrical pry bar body 1. Two pry plates 3 are arranged in a "Y" shape at one end of the pry bar body 1. The surfaces of the two pry plates 3 are opposite each other, and the opposite sides of the two pry plates 3 are connected to the sidewall of the pry bar body 1 via hinged locking components. A fulcrum bolt 2, parallel to the surface of the pry plates 3, is also connected to the sidewall of the pry bar body 1 between the two pry plates 3.

[0029] When using this tool to disassemble the tubular MBR membrane module, first loosen the nuts on the clamping assembly at the top of the MBR membrane module; then, adjust the opening angle of the two pry plates 3 according to the size of the MBR membrane module by using the hinge locking assembly to make it fit the size of the MBR membrane module; next, clamp the two pry plates 3 on both sides of the connection between the MBR membrane module and the pin, so that the upper edges of the two pry plates 3 on opposite sides abut against the two sides of the lower end of the MBR membrane module; at the same time, abut the fulcrum bolt 2 against the mounting bracket at the bottom of the pin; finally, using the lever principle, the operator can press down the pry bar body 1 to pry the MBR membrane module upward, thereby realizing the disassembly of the tubular MBR membrane module.

[0030] Therefore, this tool can easily disassemble tubular MBR membrane modules. Compared to manually pulling out tubular MBR membrane modules, this device utilizes the lever principle, making it more convenient and labor-saving. Furthermore, compared to manual pulling, the pry bar 3 requires less space, thus avoiding the problem of low disassembly efficiency due to narrow spacing between adjacent MBR membrane modules, making manual force application difficult. Its disassembly efficiency is at least five times higher than manual disassembly. Moreover, compared to the force deviation caused by manual pulling, the tool's force direction is more stable, thereby reducing the probability of damage to the MBR membrane module. In addition, since the opening angle of the two pry bars 3 can be adjusted through the hinged locking assembly, this tool can accommodate MBR membrane modules of various sizes, thus having a wide range of applications.

[0031] To adjust the opening angle of the two pry bar plates 3, the hinge locking assembly includes a hinge lug 5, a hinge bolt 6, and a long, narrow hinge member 4. The hinge lug 5 is welded to the side wall of the pry bar body 1, and its surface is perpendicular to the surface of the pry bar plate 3. The threaded end of the hinge bolt 6 passes through the hinge lug 5 and is threaded into one side of the hinge member 4. The other side of the hinge member 4 extends to the surface of the pry bar plate 3 and is welded to it. Thus, the pry bar plate 3 can rotate about the hinge bolt 6 as the hinge axis, thereby adjusting the opening angle of the two pry bar plates 3.

[0032] In this embodiment, to prevent the opening angle of the two pry plates 3 from changing arbitrarily, an arc-shaped notch 51 is provided on the surface of the hinge ear plate 5 on one side of the hinge bolt 6, with the hinge bolt 6 as the center. A locking bolt 7 is provided in the arc-shaped notch 51, with the end of the screw passing through the hinge ear plate 5 and the hinge member 4 in sequence and being threadedly connected to the hinge member 4. By turning the locking bolt 7, the opening angle of the two pry plates 3 can be adjusted and locked, thereby preventing the opening angle of the two pry plates 3 from changing arbitrarily.

[0033] Meanwhile, to enhance the structural strength of the connection between the skid 3 and the hinge 4, the hinge 4 on the skid 3 extends in the same direction as the skid 3, forming a structure similar to a reinforcing rib. Furthermore, to prevent the hinge 4, which acts as a reinforcing rib, from affecting the insertion of the skid 3 between adjacent MBR membrane modules, the cross-sectional area of ​​the hinge 4 on the skid 3 in this embodiment gradually decreases along its extending direction.

[0034] Furthermore, regarding the fulcrum bolt 2, in this embodiment, the fulcrum bolt 2 is installed through the pry bar body 1, and the fulcrum bolt 2 and the pry bar body 1 are connected by threads. Therefore, the operator can adjust the distance between the lever fulcrum and the lever as needed, making it more convenient to use.

[0035] It is important to note that:

[0036] In order to enable the tool to flexibly adjust the lever arm length according to actual needs, the outer side wall of the other end of the pry bar body 1 in this embodiment is also provided with external threads for installing the extension tube 8.

[0037] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
