An overall structural schematic of a fabricated module in accordance with an embodiment of the present disclosure is shown in fig. 1. A schematic diagram of the overall structure of the membrane module 20 in an embodiment of the present disclosure is shown in fig. 2. In the example of fig. 1 and 2, the fabricated membrane module includes a frame 10, a first number of membrane modules 20, a water tube module 31 forming a water collection line 30, and a gas tube module 41 forming a gas supply line 40. The first number of the membrane modules 20 are detachably installed at intervals in the frame 10 in a predetermined direction. Illustratively, the first number is adjustable. The preset direction may be the length direction of the frame 10, and in another embodiment, the preset direction may be other directions. The membrane assembly 20 includes a purifying member 21 and an aeration member 22 provided at the bottom of the purifying member 21. Illustratively, the aeration member 22 is detachably disposed at the bottom of the cleaning member 21, so that the cleaning member 21 or the aeration member 22 can be individually replaced or maintained at a later stage, and the overall replacement cost can be reduced.

In the example of fig. 1 and 2, the water line assembly 31 includes a second number of water collection lines 311 that are removably in sealed communication. The second number is matched with the first number. So that each of the membrane modules 20 can communicate with one of the water collecting pipes 311 at a corresponding position for the liquid purified by the purifying member 21 to flow to the water pipe module 31. That is, the second number is adjustable in coordination with the first number. The air tube assembly 41 includes a third number of air supply tubes 411 in removable sealed communication. The third number cooperates with the first number to allow each of the membrane modules 20 to communicate with one of the gas supply pipes 411 at a corresponding location. Referring to the example of fig. 1, a plurality of air outlets 41101 are provided at the bottom of the air pipe assembly 41, and each air outlet 41101 of the air pipe assembly 41 communicates with each aeration member 22 via the connection pipe 23 of the membrane assembly 20. That is, the third number is adjustable in coordination with the first number.

In the present embodiment, a certain number of the membrane modules 20 may be mounted to the frame 10 according to the need. The number of the water collecting pipes 311 and the air supply pipes 411 is adjusted according to the number of the membrane modules 20, so as to realize the communication between the water collecting pipeline 30 and the air supply pipeline 40 and the membrane modules 20. Through the modularization assembly, the customized configuration can be rapidly carried out according to the actual quantity demand and the assembly can be carried out. Illustratively, the water tube assembly 31 and the air tube assembly 41 are closed at both ends and are identical in structure. In this case, taking the water pipe assembly 31 as an example, the water collecting pipes 311 in the middle are implemented as two-way pipes 311A, and a plurality of water collecting ports 31101 are formed at the bottom of the two-way pipes 311A, and illustratively, the two-way pipes 311A are different in part, for example, two water collecting ports 31101 are formed at the bottom of part of the two-way pipes 311A, and a water collecting port is also formed at the top of part of the two-way pipes 311A. The water collecting pipes 311 at two ends of the water pipe assembly 31 are implemented as a single-pass pipe 311B and a plugging head 311C, one water collecting port 31101 is formed at the bottom of the single-pass pipe 311B, two water collecting ports 31101 are formed at the bottom of the single-pass pipe, and the plugging head 311C does not have the water collecting ports 31101 and only plays a role in plugging. In this way, during assembly, a worker can select the water collecting pipes 311 with the number and type being matched according to the number of the membrane modules, and assemble the water pipe modules 31 as required. For example, the number of the membrane modules 21 is even, after the two-way pipes 311A are inserted and connected, the single-way pipes 311B with two water collection ports 31101 formed at the bottom are respectively inserted into two ports after the two-way pipes 311A are inserted and connected, or the two plugging heads 311C are respectively inserted into two ports after the two-way pipes 311A are inserted and connected, so as to form the closed water collection pipeline 30. for example, the membrane modules 21 may be odd in number, after the two-way pipes 311A are inserted and connected, the single-way pipe 311B with one water collecting port 31101 at the bottom is inserted into one of the ports after the two-way pipes 311A are inserted and connected, and finally the plugging head 311C is inserted into the other port after the two-way pipes 311A are inserted and connected, so as to form the closed water collecting pipeline 30. The assembly of the air pipe assembly 41 is the same as that of the water pipe assembly 31, and thus will not be described herein. The water collecting pipe 30 and the air supply pipe 40 for fitting the membrane modules composed of different numbers of the membrane modules 21 can be assembled quickly by this way of the splice assembly. When any one of the water collecting pipe 311 or the air supply pipe 411 in the water collecting assembly 31 and the air pipe assembly 41 leaks, a worker can only take down any one of the water collecting pipe 311 or the air supply pipe 411 that leaks and replace the same type (standard or non-standard) of water collecting pipe 311 or the air supply pipe 411, so that the operation is simple and the maintenance and replacement costs are low.

The water pipeline and the air pipeline on the traditional assembled membrane group device are composed of an independent pipe body and a plurality of interfaces formed at the bottom of the pipe body, and the integrated degree is high. However, when the integrated water pipeline and air pipeline are assembled to the membrane assembly device composed of different numbers of membrane assemblies, a plurality of water pipelines and air pipelines with different numbers of interfaces are manufactured according to the different numbers of the membrane assemblies, so that the time cost and the economic cost of production are high. Or plugging a longer air pipeline and redundant interfaces on the water pipeline, and then assembling. However, since both the water collecting pipe 30 and the air supply pipe 40 are placed below the liquid level in actual use, this method is prone to leakage of the plugged interface in subsequent use, and requires shutdown for re-plugging once leakage occurs. If the water pipeline and the air pipeline are damaged somewhere, the water pipeline or the air pipeline needs to be replaced integrally, and the mode not only increases the workload of replacement and maintenance, reduces the efficiency, but also increases the maintenance and replacement cost. Thus, a modular membrane module in accordance with embodiments of the present disclosure may also reduce the time and economic costs of later repair and replacement.

A schematic cross-sectional view of a water collection line 30 in an embodiment of the present disclosure is shown in fig. 3. An enlarged view of a of fig. 3 is shown in fig. 4, in an embodiment of the present disclosure. In the examples of fig. 3 and 4, the sealed communication is illustratively implemented as a plug-in connection. Illustratively, the water collecting pipe 311 has a first insertion portion 3111 formed at one end and a first receiving portion 3112 formed at the other end, and the first insertion portion 3111 is inserted into the first receiving portion 3112 of the other water collecting pipe when two adjacent water collecting pipes 311 are connected by plugging. In another example, the sealed communication may be implemented as a threaded connection or a flanged connection.

A schematic cross-sectional view of the air supply line 40 in an embodiment of the present disclosure is shown in fig. 5. An enlarged view of B in fig. 5 of an embodiment of the present disclosure is shown in fig. 6. In the examples of fig. 5 and 6, the sealed communication is illustratively implemented as a plug-in connection. Illustratively, the air supply pipe 411 has a second insertion portion 4111 formed at one end and a second receiving portion 4112 formed at the other end, and the second insertion portion 4111 is inserted into the second receiving portion 4112 of the other air supply pipe 411 when two adjacent air supply pipes 411 are connected in an inserted manner. A guide structure (not shown) is further formed between the second insertion portion 4111 and the second receiving portion 4112, so that the plurality of air outlets 41101 are linearly spaced apart on the same straight line. Accordingly, a guide structure (not shown) is also formed between the first insertion part 3111 and the first receiving part 3112. In another example, the sealed communication may be implemented as a threaded connection or a flanged connection.

In the example of fig. 3 and 4, at least one first seal 312 is provided between the water collecting pipe 311 and the adjacent other water collecting pipe 311. Illustratively, the plurality of first seals 312 are provided at intervals along the longitudinal direction of the water collecting pipe 311 in a region where the first insertion portion 3111 overlaps the first receiving portion 3112. After the water collecting pipes 311 are inserted, the first sealing member 312 deforms to fill a part of the gap between two adjacent water collecting pipes 311, so as to improve the sealing effect between two adjacent water collecting pipes 311.

In the example of fig. 5 and 6, at least one second seal 412 is provided between the gas supply pipe 411 and another adjacent gas supply pipe 411. Illustratively, the second seals 412 are provided in plural, and the second seals 412 are provided at intervals along the longitudinal direction of the gas supply pipe 411 in the region where the second insertion portion 4111 overlaps the second housing portion 4112. After the air supply pipes 411 are inserted, the second sealing member 412 deforms to fill a portion of the gap between two adjacent air supply pipes 411, thereby improving the sealing effect between two adjacent air supply pipes 411. In another embodiment, the first seal 312 may also be implemented as one and the same length as the first insertion portion 3111. The second sealing member 412 may be implemented as one, and has the same length as the second insertion portion 4111.

Illustratively, since the adjacent two membrane modules 20 are installed at intervals to the frame 10, friction between the adjacent two water collecting pipes 311 may prevent the separation of the two water collecting pipes 311 connected by plugging after the connection of the two water collecting pipes 311 connected by plugging with the adjacent two membrane modules 20. Secondly, when the water collecting pipeline 30 receives impact separation force, the adjacent two membrane assemblies 20 with fixed positions can enable the water collecting pipes 311 to keep the state of being inserted into the other water collecting pipe 311, so that the two water collecting pipes 311 connected in an inserted manner are prevented from being separated, and the fixing effect between the two water collecting pipes 311 connected in an inserted manner is improved.

In another embodiment, the gas collecting pipe 311 has the same size as the gas supply pipe 411, and the water collecting port 31101 of the gas collecting pipe 311 has the same structure as the gas outlet 41101 of the gas supply pipe 411, so that the gas collecting pipe 311 may communicate with the aeration member 22 of the membrane module 20, and the gas supply pipe 411 may communicate with the purification member 21 of the membrane module 20. That is, the gas collecting pipe 311 and the gas supply pipe 411 may be mixed to further reduce manufacturing and maintenance costs.

A schematic structural diagram of an assembled partial membrane module 20 in an embodiment of the present disclosure is shown in fig. 7. In the example of fig. 7, the bottom of each of the water collecting pipes 311 has at least one water collecting port 31101 communicating with the purifying member 21. Illustratively, the bottom of each of the water collection pipes 311 has two water collection ports 31101 communicating with the purifying member 21. Returning to the example of fig. 2, a water outlet 2101 is formed at the top of the purifying member 21 and is communicated with the inside of the purifying member, and the water outlet 2101 is detachably connected with the water collecting port 31101 at a corresponding position so that the purified liquid on the upper side of the purifying member 21 flows to the water collecting pipeline 30. Illustratively, the water collection port 3101 is also in fluid communication with the underside of the interior of the purifying member 21 via a fluid line for fluid purified from the underside of the purifying member 21 to flow to the water collection line 30. The bottom of each of the air supply pipes 411 has at least one air outlet 41101 communicating with the aeration member 22. Illustratively, the bottom of each of the air supply pipes 411 has two air outlets 41101 communicating with the cleaning member 21. Illustratively, the air outlet 41101 is removably coupled to the purifying member 21. Each of the air outlets 41101 of the air pipe assembly 41 is connected to each of the aeration elements 22 via an air line of the membrane assembly 20. That is, the number of the membrane modules 20 is the same as the number of the water collection ports 31101 of the water collection pipe 311 and the air outlet 41101 of the air supply pipe 411.

In the example of fig. 7, a water outlet 31102 is formed at the top of the water collecting pipe 311 at the center of the water pipe assembly 31, which communicates with the water collecting pipe 30. The outlet 31102 communicates with an external water pump or other device. An air inlet port 41102 communicating with the air supply line 40 is formed at the top of the air supply pipe 411 at the center of the air pipe assembly 41. The inlet port 41102 communicates with an external source of air. It will be appreciated that the user can keep the water outlet 31102 and the air inlet 41102 at a central position all the time by adding and removing the water collecting pipe 311 and the air supply pipe 411 at the end portions when assembling the water collecting pipe 30 and the air supply pipe 40, so as to maintain uniformity of air supply, and at the same time avoid the problem that the individual membrane modules 20 are too close or too far apart to generate more or less water. For example, the water outlet 31102 and the air inlet 41102 are connected to the outside by flange connection.

In the example of fig. 7, the frame 10 includes an upper frame 11 and a lower frame 12. Illustratively, the upper frame 11 includes four upper mounting plates 111, and the four upper mounting plates 111 are connected end to end and enclose the upper assembly space 1101. The purifying member 21 is detachably mounted to the upper assembly space 1101. Illustratively, the lower frame 12 includes four lower mounting plates 121, and the four lower mounting plates 121 are connected end to end and enclose the lower assembly space 1201. The aeration member 22 is detachably installed in the lower fitting space 1201. Further exemplary, the purifying member 21 and the upper frame 11 and the aerating member 22 and the lower frame 12 are mounted by screws. In another embodiment, the installation mode of the purifying member 21 and the upper frame 11 and the installation mode of the aerating member 22 and the lower frame 12 may be a fastening structure or a bolt structure. In the example of fig. 7, the bottom of the lower frame 12 is further provided with a plurality of support legs 122 for preventing the aeration members 22 from contacting the bottom of the tank. Thus, the situation that the aeration member 22 cannot work normally due to the contact of the aeration member 22 with the tank bottom can be avoided. In another embodiment, the upper frame 11 and the lower frame 12 may be connected by a plurality of connecting rods (not shown) to enhance the overall strength.

Illustratively, when only a part of the membrane module 20 is assembled in the frame 10, a placement space is formed between the frame 10 and the outermost membrane module 20, and the placement space may place some components that are matched with the membrane module device. For example, when only a part of the membrane module 20 is assembled in the frame body 10, a worker can install an installation tool located outside the upper frame 11 into the placing space, and thus, the worker can use the assembled membrane module device more conveniently because the installation tool is not exposed.
