DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a multi-stage separation membrane of a decentralized sewage treatment device comprises a main membrane 1, and a pressure relief structure 2 is arranged outside the main membrane 1;

[0025] The pressure relief structure 2 includes a concave membrane 3, which is fixedly arranged on the outer side of the main membrane 1, and is meshedly connected with a convex membrane 4, and the outer side of the convex membrane 4 is fixedly connected with a diamond membrane 5, and a concave membrane 2 6 is fixedly arranged on the inner side of the main membrane 1, and the concave membrane 2 6 is meshedly connected with a convex membrane 2 7, and the inner side of the convex membrane 2 7 is fixedly connected with a diamond membrane 2 8.

[0026] When sewage flows into diamond membrane 28, it will quickly fill the inside of diamond membrane 28, and then pass through diamond membrane 28, convex membrane 27, concave membrane 26, main membrane 1, concave membrane 13, convex membrane 14, diamond membrane 15, and finally flow out from diamond membrane 15. During the process, the sewage will generate water pressure acting on diamond membrane 28. Diamond membrane 28 is suitable for deformation to relieve water pressure due to its diamond-shaped internal structure. Diamond membrane 28 is deformed by water pressure, making the meshing between concave membrane 26 and convex membrane 27 and between concave membrane 13 and convex membrane 14 more firm, thereby making diamond membrane 15 also make corresponding deformation, and finally making the separation membrane as a whole adapt to the water pressure while strengthening the internal stability.

[0027] In this embodiment, the concave film 1 3 and the convex film 1 4 are meshed and matched, and the concave film 2 6 and the convex film 2 7 are meshed and matched.

[0028] The concave membrane 3 cooperates with the convex membrane 4, and the concave membrane 2 6 cooperates with the convex membrane 2 7 to make the internal structure of the separation membrane more solid.

[0029] In this embodiment, the internal intermediate structures of the rhombus membrane 1 5 and the rhombus membrane 2 8 are distributed in a rhombus shape.

[0030] The arrangement of the diamond membrane 1 5 and the diamond membrane 2 8 enables the separation membrane to better adapt to water pressure.

[0031] In this embodiment, a connecting structure 9 is provided at both ends of the main membrane 1, concave membrane 1 3, convex membrane 1 4, diamond membrane 1 5, concave membrane 2 6, convex membrane 2 7, and diamond membrane 2 8. The connecting structure 9 includes a connecting head 10 and a connecting head 2 12. The connecting head 10 and the connecting head 2 12 are fixedly provided at the two ends of the main membrane 1, concave membrane 1 3, convex membrane 1 4, diamond membrane 1 5, concave membrane 2 6, convex membrane 2 7, and diamond membrane 2 8, respectively.

[0032] When two adjacent separation membranes need to be connected, the connector 2 12 of the separation membrane at one end is inserted into the groove at one end of the connector 10 of the adjacent separation membrane. When it is fully inserted, the arc-shaped clamping plate 11 is pulled to slide in the slide groove of the connector 10 and finally inserted into the reserved groove of the connector 2 12, so that the two adjacent separation membranes can be connected.

[0033] In this embodiment, a groove is formed at one end of the first connector 10 , and the groove is adaptively matched with the second connector 12 .

[0034] The arrangement of the groove enables the second connector 12 of two adjacent separation membranes to be connected to the first connector 10.

[0035] In this embodiment, a slide groove is provided on the outside of the first connector 10, an arc-shaped clamping plate 11 is slidably provided on the inner side of the slide groove, and a reserved groove is provided at one end of the second connector 12.

[0036] The arrangement of the arc-shaped clamping plate 11 has a role in limiting the position of the second connector 12 .

[0037] In this embodiment, the arc-shaped clamping plate 11 is adaptively matched with the connecting head 2 12, and the connecting head 10 and the connecting head 2 12 are adaptively matched with the main membrane 1, the concave membrane 1 3, the convex membrane 1 4, the diamond membrane 1 5, the concave membrane 2 6, the convex membrane 2 7, and the diamond membrane 2 8.

[0038] The reserved groove cooperates with the arc-shaped clamping plate 11 to facilitate the rapid connection and fixation of two adjacent separation membranes.

[0039] It should be noted that the utility model is a multi-stage separation membrane of a decentralized sewage treatment device. When in use, it is placed at a site where it needs to work, so that it can reach the working operating conditions;

[0040] During the process, when sewage flows into the diamond membrane 28, the sewage will quickly fill the inner side of the diamond membrane 28, and then pass through the diamond membrane 28, the convex membrane 27, the concave membrane 26, the main membrane 1, the concave membrane 13, the convex membrane 14, the diamond membrane 15, and finally flow out of the diamond membrane 15. During the process, the sewage will generate water pressure acting on the diamond membrane 28. Since the internal structure of the diamond membrane 28 is a diamond, it is suitable for deformation to relieve the water pressure. The diamond membrane 28 is deformed by the water pressure, making the meshing between the concave membrane 26 and the convex membrane 27 and the concave membrane 13 and the convex membrane 14 more firmly, thereby making the diamond membrane 15 also make corresponding deformation, and finally making the separation membrane as a whole adapt to the water pressure while strengthening the internal stability;

[0041] During the process, when two adjacent separation membranes need to be connected, the connector 2 12 of the separation membrane at one end is inserted into the groove at one end of the connector 10 of the adjacent separation membrane. When it is fully inserted, the arc-shaped clamping plate 11 is pulled to slide in the slide groove of the connector 10 and finally inserted into the reserved groove of the connector 2 12, so that the two adjacent separation membranes can be connected.

[0042] The main film 1, the concave film 3, the convex film 4, the rhombus film 5, the concave film 6, the convex film 7, the rhombus film 8 are all polyamide films.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
