The length direction of the top flow-through pipe 300, i.e., the arrangement direction of the filtering membrane modules 100, is perpendicular to the arrangement direction of the filtering unit rows 10. As shown in fig. 1, the number of the filter membrane assemblies 100 in each filter unit row 10 is 5, but the number is not limited to 5, and may be more than 5, or less than 5.

As shown in fig. 3, fig. 3 shows a front view of the filtration membrane module 100, the filtration membrane module 100 includes an upper end cap 101, a filter element 102 and a lower end cap 103, wherein the upper end cap 101 and the lower end cap 103 are respectively disposed at the upper end and the lower end of the filter element 102. The upper end cover 101 is provided with a first through cavity 1011 penetrating through the upper end cover 101 along the length direction of the top flow passing pipe 300, and the top of the upper end cover 101 is provided with a water outlet 1012 communicated with the top flow passing pipe 300. In fig. 3, the first through channel 1011 penetrates the upper end cover 101 just along the radial direction of the upper end cover 101 to form a sewage outlet on the left and right sides of the upper end cover 101. As shown in fig. 4, the lower cover 103 is provided with a second through channel 1031 arranged along the length direction of the top flow pipe 300 and an air intake passage 1032 communicated with the second through channel 1031. In fig. 4, the second through channel 1031 penetrates the lower end cover 103 along the radial direction of the lower end cover 103 to form a raw water inlet on each side of the lower end cover 103. The air inlet channel 1032 extends along a radial direction of the second through channel 1031, and two ends of the air inlet channel 1032 are respectively defined as a first end 1033 and a second end 1034, wherein the first end 1033 is opened at a side wall of the lower end cover 103, and the second end 1034 is communicated with the second through channel 1031. The filter cartridge 102 of the filter membrane assembly 100 includes a housing and a filter membrane stack disposed within the housing. The upper and lower ends of the housing are connected to the upper and lower end caps 103, respectively. In the embodiment of the present invention, the specific structure of the filter element 102 and the filter membrane set therein is not limited.

When the filter membrane modules 100 are spliced to form the filter unit row 10, the first through cavities 1011 of adjacent filter membrane modules 100 are connected together, and the second through cavities 1031 of adjacent filter membrane modules 100 are also connected together. Thus, the two sides of the upper end of the obtained filtering unit row 10 are both provided with sewage outlets, and a plurality of water outlets 1012 at the upper end are pure water outlets and are all communicated with the top overflow pipe 300; both sides of the lower end of the obtained filter unit row 10 are provided with raw water inlets. When the filtration unit row 10 is used for water purification, one of the sewage outlets and one of the raw water inlets may be plugged, and then water is introduced from the other raw water inlet, and the purified water generated by each filtration membrane module 100 is converged to the top overflow pipe 300 through each water outlet 1012. The manner in which the first through channels 1011 of adjacent filter membrane modules 100 are butted is not limited and may be configured to be directly butted or connected by an intermediate joint. The abutting manner of the second through-channels 1031 of adjacent filtering membrane modules 100 is not limited, and may be directly abutted or connected by an intermediate joint.

It should be noted that, in other embodiments, the filter element 102 may also be configured such that the left and right sides of the upper end cover 101 form a clean water port, and the top of the upper end cover 101 forms a sewage discharge port. At this time, the water purification ports of the filtering membrane modules 100 in the filtering unit row 10 are sequentially connected in series, and the sewage flowing out of the sewage discharge port of each filtering membrane module 100 is converged to the top overflow pipe 300.

The bottom support 200 is used to support each filter membrane module 100 in the filter unit row 10, wherein the lower end cap 103 of each filter membrane module 100 is fixed to the bottom support 200. In use, the base support 200 is placed on an installation base, such as directly on the ground or in a water purification unit.

Further, in order to simplify the duct structure and the frame structure of the filtration module, as shown in fig. 1, in an embodiment of the present invention, the bottom support 200 further has an air duct 201 extending along the length direction of the top flow pipe 300, and has the same number of interfaces 202 as the number of the air inlet channels 1032, wherein the interfaces 202 are in one-to-one correspondence, the air inlet channels 1032 on the lower end cover 103 are communicated with the air duct 201, and it can be understood that the air duct 201 has an inlet for connecting an external air source. As shown in fig. 1, the filter unit row 10 includes 5 filter membrane modules 100, and there are 5 air inlet channels 1032 in total. Correspondingly, the air channel 201 of the bottom support 200 is provided with 5 interfaces 202 to connect with 5 air inlet channels 1032 in a one-to-one correspondence.

After each filter membrane module 100 is secured to the base support 200, the air inlet channel 1032 of each filter membrane module 100 communicates with the air channel 201 of the base support 200 through an interface 202. After the air duct 201 is connected with an external air source, the air is divided in the air duct 201 to flow into the lower end cover 103 of each filter membrane module, so that aeration is realized in each filter membrane module 100.

In the filter module, the bottom support 200 is placed on an installation base such as the ground when in use, and the bottom support 200 serves as a gas supply pipe in addition to supporting the filter unit rows 10, thereby saving redundant gas supply pipes, reducing the volume of the filter module, and simplifying the structure. In addition, the upper end and the lower end of the filtering membrane component 100 are respectively provided with a through cavity, a conveying pipeline is formed after the filtering membrane components 100 are communicated, a water inlet pipeline and a water production pipeline do not need to be additionally arranged, the space is also saved, and the cost is reduced.

As shown in fig. 4, the lower end cap 103 of the filtration membrane module 100 is provided with a stopper 1035 coupled to the bottom support 200, and the stopper 1035 is detachably coupled to the bottom support 200. The filtration membrane assembly 100 is removably coupled to the base support 200 for ease of installation and later maintenance. In one embodiment, the limiting structure 1035 is a groove that engages with the bottom support 200. The implementation of the filter membrane assembly 100 detachably coupled with the bottom support 200 is not limited to the above examples, and may be in other forms. For example, the lower end cap 103 of the filtering membrane module 100 may be configured to be fastened to the bottom support 200 by bolts and nuts.

In order to facilitate the connection between the interface 202 of the bottom support 200 and the air inlet channel 1032 of the filter membrane module 100, in some embodiments, the bottom support 200 has a hollow tubular shape, the lumen of the hollow tube is the air passage 201, and the interface 202 and the air inlet channel 1032 are connected by the conduit 203. The air inlet channel 1032 is connected with the interface 202 by the pipe 203, and the installation and maintenance are convenient. In particular, the bottom support 200 is a hollow tube with a square cross-section. It should be noted that the cross-sectional shape of the bottom support 200 is not limited to a square shape, but may be other regular shapes. The position where the port 202 is provided above the circumference of the bottom supporter 200 so as to operate to connect the pipe 203 is not limited. The pipe 230 may be a flexible hose, a bent stainless steel pipe, a plastic pipe, or the like.

As can be seen from fig. 1 and 2, in one embodiment, the positioning plates 400 are spaced apart from the upper and lower ends of the adjacent filter unit rows 10, so that the integrity of all the filter unit rows 10 is improved. Specifically, along the length direction of the top overflow pipes 300 of the filter unit rows 10, the positioning plates 400 between the upper end caps 101 of the filter membrane assemblies 100 between two adjacent filter unit rows 10 are arranged at intervals; in addition, in the filtering membrane modules 100 in the same row in the arrangement direction of the filtering unit rows 10, the positioning plates 400 are arranged at intervals between the upper end caps 101 of the adjacent filtering membrane modules 100. Similarly, along the length direction of the top overflow pipe 300 of the filter unit rows 10, the positioning plates 400 between the lower end caps 103 of the filter membrane assemblies 100 between two adjacent filter unit rows 10 are arranged at intervals; in the arrangement direction of the filter unit rows 10, the positioning plates 400 are provided at intervals between the lower end caps 103 of the adjacent filter membrane modules 100 in the same row. Through the means, the positioning plates 400 are arranged at the upper end and the lower end between every two adjacent filtering unit arrays 10 at intervals, so that the integrity of all the filtering unit arrays 10 is better, and the using number of the positioning plates 400 is saved on the premise of ensuring the integrity. It should be noted that the positioning plate 400 may be provided only between the upper ends of the adjacent filter unit rows 10, or the positioning plate 400 may be provided only between the lower ends of the adjacent filter unit rows 10.

In other embodiments, the positioning plates 400 may be arranged in sequence, i.e., continuously. For example, the positioning plate 400 is disposed between the upper end caps 101 of the filtering membrane modules 100 between two adjacent filtering unit rows 10, and the positioning plate 400 is disposed between the upper end caps 101 of the filtering membrane modules 100 between any two adjacent filtering unit rows 10 along the length direction of the top overflow pipe 300 of the filtering unit row 10; meanwhile, in the arrangement direction of the filter unit rows 10, in the filter membrane modules 100 in the same row, a positioning plate 400 is disposed between the upper end caps 101 of any two adjacent filter membrane modules 100.

Further, the bottom support 200 may be provided to have a splicing structure. In this way, the splicing structure of the bottom support members 200 of two adjacent filter element rows 10 can be butted together, thereby further increasing the stability of the whole filter module. The splicing structure may specifically be a concavo-convex structure.

In some embodiments, the positioning plate 400 is connected to the upper cover 101 or the lower cover 103 by fasteners 500, and the positioning plate 400 is disposed between adjacent fasteners 500. As shown in fig. 1, in an example, the positioning plate 400 between the upper end covers 101 is provided as an example, the fastening members 500 are hoops, and each of the upper end covers 101 is provided with a hoop, and the hoop locks the positioning plate 400 while holding the upper end cover 101 tightly. Thus, two ends of each positioning plate 400 are respectively locked by one hoop, so that two adjacent upper end covers 101 are connected together through the positioning plate 400. The positioning plate 400 between the lower end caps 103 is similarly arranged, and is not described in detail.
