Currently, MBR membrane elements mainly include flat plates and hollow fibers. The MBR membrane element mainly comprises a membrane element supporting plate and a separation membrane, and the separation membrane is combined with the membrane element supporting plate into a whole in the modes of glue adhesion, hot melt welding and ultrasonic welding. A plurality of MBR membrane elements are vertically stacked together to be fixed on a membrane box body, and an air explosion device is arranged below the membrane box body to form a flat-plate MBR membrane assembly. In the using process of the flat MBR membrane assembly, the flat MBR membrane assembly is immersed in a biochemical pool to be treated, activated sludge in the biochemical pool is blocked outside the separation membrane, produced water flows into the supporting plate through the separation membrane, and finally is collected into the water guide port to be pumped out. The whole process needs to continuously explode gas, bubbles in water are utilized to rise, the surface of the separation membrane is flushed, the separation membrane is prevented from being blocked by activated sludge, and the needed oxygen can be provided for microbial degradation in the process of exploding gas.

Another core of the present utility model is to provide an MBR membrane module having the above-mentioned flat plate type MBR membrane element support plate.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 3, the embodiment of the present utility model discloses a flat-plate type MBR membrane element supporting plate for improving a conventional flat-plate type MBR membrane element supporting plate, so that when an MBR membrane element is taken out, an inclination of an MBR membrane element which is not taken out is not caused, thereby facilitating replacement of a new MBR membrane element. The flat-plate MBR membrane element consists of a flat-plate MBR membrane element supporting plate, a flow guide layer and a separation membrane, and the three are combined together by welding or other sealing modes. The plate surface with larger area of the flat-plate MBR membrane element supporting plate is a plate surface for arranging the separation membrane, and for convenience of description, the plate surface for arranging the separation membrane is defined as a first plate surface and a second plate surface.

In this embodiment, the flat-plate MBR membrane element support plate includes a support plate body 101, a first clamping and positioning portion 102, and a second clamping and positioning portion 103. The larger plate surface of the supporting plate body 101 is a first plate surface and a second plate surface, which are two opposite plate surfaces of the supporting plate body 101.

The first clamping and positioning portion 102 is disposed on the first board surface, the first clamping and positioning portion 102 includes a first clamping groove 1023, and the first clamping groove 1023 has an opening facing the first side of the support board body 101. The second clamping and positioning portion 103 is configured to be clamped by the first clamping and positioning portion 102 on the adjacent support plate body 101, and is disposed on the second plate surface. The second clamping and positioning part 103 comprises a first clamping block 1031, the first clamping block 1031 extends towards the direction of the second side edge of the supporting plate body 101 and is used for being matched with the first clamping groove 1023 of the adjacent flat plate type MBR membrane element supporting plate in a clamping mode, the first side edge and the second side edge of the supporting plate body 101 are two opposite side edges, and an opening is formed in the end portion of the first clamping groove, so that the flat plate type MBR membrane element can be inserted through the end portion of the first clamping groove to achieve the assembled state. The first clamping and positioning portion 102 and the second clamping and positioning portion 103 may be integrated with the support plate body 101, or may be fixed on the support plate body 101 by other processes, for example, by welding or fastening assembly.

After the flat-plate type MBR membrane element is installed, the supporting plate body 101 is usually in a vertical state, and taking the vertical state of the supporting plate body 101 as an example, the first plate surface and the second plate surface are perpendicular to the horizontal plane. The first side and the second side of the support plate body 101 are also perpendicular to the horizontal plane. If the first side and the second side are long sides of the support plate body 101 (generally rectangular structure), the installation direction of the flat-plate MBR membrane element at least includes installing along the direction parallel to the wide side of the support plate body 101 from the first side to the second side; mounting along a direction parallel to the first side edge and the second side edge from bottom to top; and is mounted in a top-to-bottom direction in a direction parallel to the first and second sides. Because the installation direction is comparatively more, therefore the requirement on installation space is lower, can select the direction that is more spacious to assemble, also can select the direction that the equipment is most convenient to assemble to improve packaging efficiency. A handle 104 is generally provided on the top of the support plate body 101 for easy access.

The first clamping and positioning part 102 and the second clamping and positioning part 103 are respectively arranged on the first plate surface and the second plate surface of the supporting plate body 101. The first clamping and positioning portion 102 has a first clamping groove 1023, and an opening of the first clamping groove 1023 faces to a first side of the supporting plate body 101. The second clamping and positioning portion 103 has a first clamping block 1031, and the first clamping block 1031 extends toward the second side of the support plate body 101. So that when installing flat MBR membrane elements, when moving along the direction from the first side edge to the second side edge of the support plate body 101, the first clamping block 1031 of the second clamping positioning part 103 on the second plate surface side can be clamped into the first clamping groove 1023 on the first plate surface side of the adjacent flat MBR membrane elements through the opening of the first clamping groove 1023, so that the two flat MBR membrane elements are fixed together, the side wall of the first clamping groove 1023 has a limiting effect on the first clamping block 1031, and the separation of the adjacent two flat MBR membrane elements can be prevented when the force in the direction perpendicular to the support plate body 101 is received.

The flat plate type MBR membrane elements need to be assembled in sequence in a frame to form an MBR membrane module. One side of the frame is provided with a first clamping and positioning part 102, and the other side of the frame is provided with a second clamping and positioning part 103. So that the flat plate type MBR membrane element assembled in the frame can be fixed through the clamping of the first clamping and positioning part 102 on the frame and the second clamping and positioning part 103 on the flat plate type MBR membrane element, and meanwhile, the second clamping and positioning part 103 on the frame can be fixed with the clamping of the first clamping and positioning part 102 on the flat plate type MBR membrane element.

Taking an MBR membrane module with 50 flat-plate MBR membrane elements as an example, the assembly process is as follows: the 1 st flat plate type MBR membrane element is clamped with the first clamping and positioning part 102 at one side of the frame through the second clamping and positioning part 103, and the 2 nd flat plate type MBR membrane element, the 3 rd flat plate type MBR membrane element and the 49 th flat plate type MBR membrane element are clamped together in sequence. The 50 th flat plate type MBR membrane element is assembled, the second clamping and positioning part 103 at one side of the 50 th flat plate type MBR membrane element is clamped with the first clamping and positioning part 102 of the 49 th flat plate type MBR membrane element, and the first clamping and positioning part 102 at the other side of the 50 th flat plate type MBR membrane element is clamped with the second clamping and positioning part 103 at the other side of the frame.

After the installation, when the 25 th flat plate type MBR membrane element is to be exchanged, the 25 th flat plate type MBR membrane element is only required to be pulled out from the upper part of the MBR membrane element along the extending direction of the first clamping groove 1023. After the 25 th flat-plate MBR membrane element is taken out, the 1 st to 24 th flat-plate MBR membrane elements are not changed in position, because the 1 st flat-plate MBR membrane element is firmly clamped with the frame, other flat-plate MBR membrane elements are clamped with the front flat-plate MBR membrane element, and the positions among the flat-plate MBR membrane elements are limited. The same 26 th to 50 th flat-plate MBR membrane elements have no position change, because the 50 th flat-plate MBR membrane element and the frame are also mutually clamped together, other flat-plate MBR membrane elements are also mutually clamped together in turn, and the flat-plate MBR membrane elements are also subjected to position limitation. The new flat-plate MBR membrane element can be easily put into the position of the original 25 th flat-plate MBR membrane element.

The flat-plate type MBR membrane element supporting plate provided by the utility model has the advantages of simplicity and convenience in installation, and is easy to take out and playback when a certain flat-plate type MBR membrane element in the assembly needs to be replaced. The MBR membrane element can be vertically held and attached to the bottom of the frame of the MBR assembly, can be attached to the side surface of the frame, does not use redundant accessories such as guide rail plates and the like, and can not only be filled through the upper part. Through the joint of first joint location portion 102 and second joint location portion 103, can be with firm combination together between the MBR membrane element, also can be with firm combination together of MBR membrane element and frame, when needs change arbitrary one of them MBR membrane element, because the position is restriction relation each other, other MBR membrane element can not take place the position slip, when putting back new MBR membrane element again, because the vacancy position can be kept for also easier when putting back.

As shown in fig. 3, the first clamping and positioning portion 102 includes a first connecting plate 1022 and a second clamping block 1021, where the second clamping block 1021 is connected to the first board through the first connecting plate 1022, so that a certain gap is formed between the second clamping block 1021 and the first board, thereby forming a first clamping groove 1023, that is, a first clamping groove 1023 is formed between the second clamping block 1021, the first connecting plate 1022 and the first board. The width of the first clamping groove 1023 in the direction from the first side edge to the second side edge of the support plate body 101 may be equal (the scheme shown in fig. 3 is a scheme with equal width), or may be set to be unequal, for example, may be set to be gradually widened from the direction close to the first connecting plate 1022 to the direction far away from the first connecting plate 1022, so as to form a flaring structure, so that the first clamping block 1031 can be conveniently clamped in, and the limiting effect can be also realized.

The second clamping and positioning portion 103 includes a second connecting plate 1032 connected to the first clamping block 1031 and the second board, so that a certain gap is formed between the first clamping block 1031 and the second board, and a second clamping groove 1033 is formed between the first clamping block 1031, the second connecting plate 1032 and the second board, and a second clamping groove 1033 is formed between the first clamping block 1031 and the second board. The second clamping block 1021 is used for being matched with the second clamping groove 1033 of the adjacent flat-plate MBR membrane element supporting plate in a clamping way. Correspondingly, the width of the second clamping groove 1033 in the direction from the second side edge to the first side edge of the support plate body 101 may be equal (the scheme shown in fig. 3 is the scheme with equal width), or may be set to be unequal, for example, the width may be gradually increased and widened in the direction from the direction close to the second connecting plate 1032 to the direction far away from the second connecting plate 1032, so as to form a flaring structure, so that the second clamping block 1021 can be conveniently clamped in, and the limiting effect can be also realized. Note that, when the first clamping groove 1023 adopts a flaring structure with gradually wider width, the first clamping block 1031 also needs to adopt a structure with gradually changed thickness to be adapted to the first clamping groove 1023. Correspondingly, when the second clamping groove 1033 adopts a flaring structure with gradually wider width, the second clamping block 1021 also needs to adopt a structure with gradually-changed thickness to be matched with the second clamping groove 1033.

Under the action of the first connection plate 1022 and the second connection plate 1032, the first clamping block 1031 and the second clamping block 1021 are at a certain distance from the plate surface, so that a certain distance is formed between two adjacent flat-plate MBR membrane elements, the distance is prevented from being too close, and bubbles generated by aeration cannot wash the membrane surface.

In an embodiment of the present utility model, the extending directions of the first card slot 1023 and the second card slot 1033 are parallel to the first side and the second side of the supporting plate body 101.

It should be noted that, the extending directions of the first clamping groove 1023 and the second clamping groove 1033 all have a certain included angle with the first side edge and the second side edge of the supporting plate body 101, the two angles are not too large as much as possible, otherwise, the installation in the frame will be affected, the frame needs to have a large enough installation space to complete the assembly, otherwise, the frame may interfere with the frame of the frame.

In this embodiment, the first connecting plate 1022 and the second clamping block 1021 are perpendicular, and the first connecting plate 1022 and the plate surface of the supporting plate body 101 are also perpendicular, so as to form a first clamping groove 1023 with equal width. Corresponding to the above. The first clamping block 1031 and the second connecting plate 1032 are perpendicular to the second connecting plate 1032 and the plate surface of the supporting plate body 101, so that a second clamping groove 1033 with the same width is formed.

It should be noted that, for convenience of assembly, the width of the first clamping groove 1023 may be designed to be greater than the thickness of the first clamping block 1031; correspondingly, the width of the second locking groove 1033 may be larger than the thickness of the second locking piece 1021. For example, the difference between the width of the first clamping groove 1023 and the thickness of the first clamping block 1031 may be designed to be about 2 mm; correspondingly, the difference between the width of the second clamping groove 1033 and the thickness of the second clamping block 1021 is designed to be about 2mm, so that the first clamping and positioning portion 102 and the second clamping and positioning portion 103 can be conveniently inserted into each other.
