[0027] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present disclosure can be applied to other implementation schemes, variation schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present disclosure.

[0028] Those skilled in the art should understand that in the disclosure of the present disclosure, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation to the present disclosure.

[0029] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the number.

[0030] In the present disclosure, unless otherwise clearly defined and limited, the terms "install", "connect", "connect", "fix", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0031] In the related art, when the membrane module filters and processes liquid, it needs to be submerged below the liquid level. For example, when the membrane module is an MBR membrane module, the MBR membrane module includes a plurality of membrane units arranged in parallel, and each membrane unit includes a plurality of hollow membrane filaments capable of filtering water and allowing microorganisms to attach. When the MBR membrane module works, the MBR membrane module needs to be submerged below the sewage level to filter and treat the sewage and perform microbial treatment. It can be understood that the membrane module in the embodiments of the present disclosure includes but is not limited to this, and can also be other membrane modules submerged in the liquid and treating the liquid.

[0032] Thus, when using a lifting tool to lift the membrane module from the liquid, for example, using a crane to lift the membrane module from the water for off-line cleaning of the membrane module, since the lifting device installed on the membrane module is submerged below the water level, it is necessary to drain water outwards to lower the liquid level so that the hanging part of the lifting device is exposed above the liquid level, which is convenient for the lifting tool to lift the membrane module. This method results in cumbersome operation and high operation cost when the membrane module is lifted.

[0033] In view of this, the embodiments of the present disclosure provide a lifting device for a membrane module. When the lifting device for the membrane module is installed on the membrane module, the hanging part of the lifting device is above the liquid level, so that the membrane module can be directly lifted without lowering the liquid level, which is convenient for the lifting operation on site of the membrane module.

[0034] Figure 1 is a schematic structural diagram of the lifting device for the membrane module in the embodiments of the present disclosure. Refer to Figure 1 The lifting device for the membrane module in the embodiments of the present disclosure includes a loading assembly 10 and a hanging frame 20.

[0035] Figure 2 is a schematic structural diagram of the lifting device for the membrane module installed on the membrane module 900 in the embodiments of the present disclosure. Refer to Figure 2 The loading assembly 10 is used to be loaded on the top surface of the membrane module 900. The hanging frame 20 is arranged on the loading assembly 10.

[0036] Thus, when installing the lifting device for the membrane module on the top surface of the membrane module 900, first load the loading assembly 10 on the top surface of the membrane module 900, and then load the hanging frame 20 on the loading assembly 10. In this way, the hanging frame 20 is installed on the top of the membrane module 900.

[0037] Figure 3 is a schematic side view of the lifting device for the membrane module installed on the membrane module 900 in the embodiments of the present disclosure. Refer to Figure 1 and Figure 3, the hanger 20 includes a plurality of hanging members 21. The plurality of hanging members 21 extend upward from the circumferential side to the center and are fixedly connected to form a suspended part 22 maintained at a certain height, so that the suspended part 22 is located above the liquid level 800 of the liquid submerging the membrane module 900. One end of the plurality of hanging members 21 at the circumferential side forms a connection end 211 for connecting to the loading assembly 10.

[0038] Specifically, for example, there are four hanging members 21. The four hanging members 21 all protrude upward from the circumferential side to the center, and the parts of the four hanging members 21 protruding to the center are fixedly connected to form a suspended part 22 maintained at a certain height, and one end of the four hanging members 21 at the circumferential side is formed as a connection end 211 for connecting to the loading assembly 10. It can be understood that the number of the hanging members 21 in the embodiments of the present disclosure includes but is not limited to this, and the number can be appropriately adjusted according to actual needs.

[0039] In other words, when the membrane module 900 works, the membrane module 900 will be submerged below the liquid level 800 of the liquid, so as to facilitate the filtration treatment of the liquid. The plurality of hanging members 21 extend obliquely, and the lower ends, that is, the connection ends 211, are connected to the loading assembly 10 away from each other and are arranged around the circumferential side of the loading assembly 10. The upper ends of the plurality of hanging members 21 are connected close to each other and form a suspended part 22 that can be lifted by a lifting tool. When the membrane module 900 works, the suspended part 22 installed on the membrane module 900 is located above the liquid level 800 of the liquid.

[0040] Specifically, when the membrane module 900 works, the distance between the top surface of the membrane module 900 and the liquid level 800 is set as the first distance, and the relative height (or distance) of the suspended part 22 relative to the top surface of the membrane module 900 is the second distance, and the second distance is greater than the first distance. In actual application, according to the actually required first distance, a suspended part 22 with the second distance from the top surface of the membrane module 900 is made, so that it can be ensured that when the membrane module hanger works, the suspended part 22 can be located above the liquid level 800.

[0041] Thus, when the lifting tool lifts the membrane module 900 from the liquid for on-line cleaning of the membrane module 900, the lifting tool can directly lift the suspended part 22 without having to drain the liquid to lower the liquid level 800. Thus, the membrane module hanger in the embodiments of the present disclosure can be directly lifted without lowering the liquid level 800, which facilitates the lifting operation of the membrane module 900 on site, and the above device has a simple structure, low cost, and is convenient for mass production.

[0042] Optionally, the suspension member 21 is made of hard metal. Such an arrangement can prevent the suspended part 22 from sagging due to the flexibility of the suspension member 21 and being immersed in the liquid, and can ensure that the suspended part 22 is kept above the liquid level 800. Specifically, the hard metal may be steel material. The steel material has good mechanical properties and can withstand a large force without deformation, which is convenient for the lifting tool to lift the membrane unit 900 smoothly.

[0043] Optionally, when there are four suspension members 21, every two suspension members 21 are connected to form an arc-shaped suspension frame that opens downward. The tops of the two arc-shaped suspension frames are welded to each other to form the suspended part 22. Thus, the suspension bracket 20 is easy to manufacture and has low cost.

[0044] Optionally, a plurality of the suspension members 21 are detachably connected to the loading assembly 10. Thus, before the membrane unit 900 is transported to the operation site, the suspension bracket 20 and the loading assembly 10 can be kept in a separated state. At this time, since the heights of both the suspension bracket 20 and the loading assembly 10 are relatively low, the problem of excessive height during the transportation of the membrane unit lifting tool can be avoided. After the membrane unit lifting tool is transported to the operation site of the membrane unit 900, the suspension bracket 20 and the loading assembly 10 can be reassembled to the membrane unit 900, and the assembly of the membrane unit lifting tool can be completed on site.

[0045] Optionally, the loading assembly 10 includes a plurality of mounting seats 11. The plurality of mounting seats 11 are loaded onto the top surface of the membrane unit 900 and are detachably connected to the connection ends 211 of the plurality of suspension members 21 in a one-to-one correspondence.

[0046] Thus, when installing the membrane unit lifting tool on site, first install the plurality of mounting seats 11 corresponding to the top surface of the membrane unit 900, and then install the plurality of suspension members 21 onto the plurality of mounting seats 11 respectively, thereby realizing the installation of the suspension bracket 20 on the membrane unit 900.

[0047] Figure 4 is Figure 1 an enlarged schematic view of part A in. Refer to Figure 1 and Figure 4 , the loading assembly 10 further includes a plurality of detachable connectors 12. The plurality of detachable connectors 12 are detachably connected between the plurality of mounting seats 11 and the plurality of suspension members 21 in a one-to-one correspondence.

[0048] Thus, through the detachable connectors 12, the detachable installation between the mounting seat 11 and the suspension member 21 is realized.

[0049] Figure 5 is Figure 1 an enlarged schematic view of part B in. Refer toFigure 5 , a connection hole 2101 is formed at the connection end 211 of the hanging member 21. A first mounting hole 1101 is formed on the mounting seat 11.

[0050] Refer to Figure 4 , the detachable connecting member 12 includes a bending portion 121 and a connecting fastener 122.

[0051] Wherein, the bending portion 121 forms a receiving opening 1201 that is open on one side and can receive the hanging member 21, and a first fastening hole 1202 and a second fastening hole 1203 located on opposite sides of the receiving opening 1201, and the bending portion 121 passes through the first mounting hole 1101. Specifically, the bending portion 121 is U-shaped, and the U-shaped bending portion 121 passes through the first mounting hole 1101.

[0052] The connecting fastener 122 passes through the first fastening hole 1202 and the connection hole 2101 and is fastened in the second fastening hole 1203. Specifically, the connecting fastener 122 can be a bolt, and the bolt passes through the first fastening hole 1202 and the connection hole 2101 and is fastened in the second fastening hole 1203.

[0053] In other words, when connecting the mounting seat 11 and the hanging member 21 together, first pass the bending portion 121 through the first mounting hole 1101 on the mounting seat 11, and then pass the connecting fastener 122 through the first fastening hole 1202 and the connection hole 2101 and fasten it in the second fastening hole 1203. Thus, the hanging member 21 is installed on the mounting seat 11. When disassembling the hanging member 21 from the mounting seat 11, pull out the connecting fastener 122 from the second fastening hole 1203, the connection hole 2101, and the first fastening hole 1202 in sequence, thereby realizing the disassembly of the hanging member 21 from the mounting seat 11, and the disassembly and assembly between the hanging member 21 and the mounting seat 11 are convenient.

[0054] Optionally, refer to Figure 1 , the loading assembly 10 further includes at least one side support member 13. The side support member 13 is connected between two adjacent mounting seats 11. Thus, the side support member 13 can bear the lateral decomposition force from the mounting seat 11, ensuring that when the membrane unit 900 is lifted, the membrane unit 900 mainly bears the force from the up and down directions, ensuring that the lifted membrane unit 900 is difficult to deform due to lifting, so that the membrane unit 900 with a large shape and gravity can be lifted well without deformation.

[0055] Optionally, the multiple mounting seats 11 are divided into multiple groups, and the mounting seats 11 of the multiple groups are arranged at intervals and oppositely along the width direction of the membrane unit 900. There are multiple side braces 13, and the multiple side braces 13 are arranged in one-to-one correspondence with the multiple groups of mounting seats 11, so as to be able to withstand the lateral decomposition force from the multiple groups of mounting seats 11 and better ensure that the lifted membrane unit 900 does not deform.

[0056] Specifically, there are two side braces 13, and the two side braces 13 extend along the length direction of the membrane unit 900 and are arranged at intervals along the width direction of the membrane unit 900, and each side brace 13 is connected between two mounting seats 11 arranged at intervals along the length direction of the membrane unit 900.

[0057] Optionally, referring to Figure 5 , the mounting seat 11 forms a second mounting hole 1102 for the mounting fastener to pass through. Thus, when the mounting seat 11 is installed on the membrane unit 900, the mounting seat 11 can be installed on the membrane unit 900 by using a mounting fastener such as a bolt, thereby realizing the loading of the mounting seat 11 on the top surface of the membrane unit 900.

[0058] Those skilled in the art should understand that the embodiments of the present disclosure described above and shown in the drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been shown and described in the embodiments, and the embodiments of the present disclosure can have any deformation or modification without departing from the principle.
