Description

Technical Field

[0001] The invention relates to a foldable flat membrane element and belongs to the technical field of water treatment. Background Art

[0002] The two membrane units of the existing flat membrane element have multiple bolt holes distributed longitudinally on both sides. When assembling them, bolts need to be inserted into the corresponding bolt holes of the two membrane units one by one. After the membrane bioreactor has been running for a period of time, the flat membrane element needs to be taken out of the box to clean the mud stuck between the membranes. At this time, it is still time-consuming and laborious to disassemble the two membrane units, and the removed bolts are also very easy to lose. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a foldable flat membrane element, the two membrane units of which are connected by folding hinges and movable buckles, so that the flat membrane element can be quickly assembled and disassembled for cleaning, greatly reducing the difficulty of cleaning the flat membrane.

[0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0005] A foldable flat membrane element consists of two flat membrane units arranged in a mirror image; one side of the two flat membrane units is rotatably connected by a folding hinge, and the other side of the two flat membrane units is connected by a movable buckle.

[0006] The flat membrane unit comprises a plastic support and a filter membrane mounted on the plastic support; one side of the plastic support is provided with a plurality of pressure plate mounting areas in the longitudinal direction, and another side of the plastic support is provided with a plurality of snap-fit ​​fixing areas at a position opposite to the pressure plate mounting area.

[0007] Among them, the pressure plate installation area is provided with symmetrically arranged threaded holes; the buckle fixing area is provided with a groove structure and threaded holes located on both sides of the groove structure.

[0008] The two flat membrane units are flat membrane unit I and flat membrane unit II respectively. The flat membrane unit I and the flat membrane unit II have the same structure and are combined into a flat membrane element in a mirror image.

[0009] Among them, the folding hinge includes a first hinge and a second hinge that are elastically connected to each other, wherein the first hinge is fixed to the snap fixing area of ​​the flat membrane unit I, and the second hinge is rotatably connected to the pressure plate II fixed to the pressure plate installation area of ​​the flat membrane unit II through a rotating shaft.

[0010] Among them, the movable buckle includes a rotating end and a protrusion located at the front end of the rotating end. The rotating end of the movable buckle is rotatably connected to the pressure plate I fixed in the pressure plate mounting area of ​​the flat membrane unit I. When the flat membrane unit I is rotated relative to the flat membrane unit II through the folding hinge until the angle between the flat membrane unit I and the flat membrane unit II is 0°, the protrusion is embedded in the groove structure.

[0011] Beneficial effects: The foldable flat membrane element of the present invention solves the difficulty of large-scale membrane disassembly and cleaning. It can unfold and overlap two membranes 360 degrees, thereby realizing the free unfolding and closing of the two membranes, thereby improving the convenience of cleaning after mud is stuck between the membranes and reducing the difficulty of cleaning the flat membrane.

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 7 As shown, the foldable flat membrane element of the present invention is composed of two flat membrane units 1 arranged in a mirror image; one side of the two flat membrane units 1 is rotatably connected by a folding hinge 9, and the other side of the two flat membrane units 1 is connected by a movable buckle 10.

[0021] The flat membrane unit 1 includes a plastic support 2 and a filter membrane 3 mounted on the plastic support 2; a plurality of pressure plate installation areas 4 are longitudinally arranged on one side of the plastic support 2, and the thickness a of the pressure plate installation area 4 is lower than the thickness b of the frame of the plastic support 2; a plurality of buckle fixing areas 5 are arranged at corresponding positions on the other side of the plastic support 2, and the thickness of the buckle fixing area 5 is also lower than the thickness of the frame of the plastic support 2; the pressure plate installation area 4 is provided with symmetrically arranged threaded holes 7; the buckle fixing area 5 is provided with a groove structure 6 and threaded holes 8 located on both sides of the groove structure 6. The plastic support 2, the folding hinge 9 and the movable buckle 10 are all made of ABS plastic.

[0022] The two flat membrane units 1 are respectively a flat membrane unit I1 - 1 and a flat membrane unit II1 - 2 . The structures of the flat membrane unit I1 - 1 and the flat membrane unit II1 - 2 are completely identical and are combined into a flat membrane element 11 in a mirror-image manner.

[0023] Among them, the folding hinge 9 includes a first hinge 91 and a second hinge 92 which are elastically connected to each other, wherein the first hinge 91 is fixed to the snap fixing area 5 of the flat membrane unit I1-1, and the second hinge 92 is rotatably connected to the pressure plate II15 fixed to the pressure plate mounting area 4 of the flat membrane unit II1-2 through a rotating shaft, and the second hinge 92 is sleeved outside the rotating shaft 17, and the end of the rotating shaft 17 extends into the through hole of the pressure plate II15 and can rotate in the through hole of the pressure plate II15. The movable buckle 10 includes a rotating end 12 and a protrusion 13 located at the front end of the rotating end 12. The rotating end 12 of the movable buckle 10 is rotatably connected to the pressure plate I14 fixed to the pressure plate installation area 4 of the flat membrane unit I1-1. The rotating end 12 is sleeved outside the rotating shaft 16, and the end of the rotating shaft 16 extends into the through hole of the pressure plate I14. When the flat membrane unit I1-1 is rotated relative to the flat membrane unit II1-2 by folding the loose-leaf 9 until the angle between the flat membrane unit I1-1 and the flat membrane unit II1-2 is 0°, the protrusion 13 is embedded in the groove structure 6 to realize the flat membrane unit I1-1 and the flat membrane unit I1-1. I1-2 is locked and fixed; when it is necessary to disassemble the flat membrane unit I1-1 and the flat membrane unit II1-2 to clean the mud stuck between the two, pull the protrusion 13 out of the groove structure 6, and rotate the flat membrane unit I1-1 relative to the flat membrane unit II1-2 by folding the hinge 9 until the angle between the flat membrane unit I1-1 and the flat membrane unit II1-2 is 180°. The flat membrane unit I1-1 is rotated relative to the flat membrane unit II1-2 by folding the hinge 9 and can be rotated to any angle, that is, the angle between the flat membrane unit I1-1 and the flat membrane unit II1-2 is 0 to 360°.
