[0001] The utility model relates to the technical field of DTRO composite diaphragms, in particular to a DTRO composite diaphragm for sewage treatment. Background Art

[0002] The DTRO composite diaphragm is a membrane module specially used for treating high-concentration sewage and belongs to a form of reverse osmosis technology. Its core technology is the disk tube diaphragm membrane column. By stacking the reverse osmosis diaphragm and the hydraulic diversion disk together, fixing them with a central pull rod and end plates, and then placing them into a pressure-resistant sleeve to form a membrane column, it is suitable for treating high-concentration sewage.

[0003] The DTRO diaphragms in the current technology usually have two layers of diaphragms, one on the front and one on the back, with a layer of diversion net sandwiched in the middle.

The fixing block drives the connecting rod to move, the connecting rod drives the adjusting block to move, and the return spring drives the adjusting block to move back to its original position, thereby assisting in the disassembly and assembly between the first flow guiding disc and the second flow guiding disc.

[0008] Preferably, protective grooves are symmetrically formed inside the first flow guiding disc. The fixing block can be protected through the arrangement of the protective grooves.

[0009] Preferably, positioning blocks are symmetrically and fixedly connected to the outer side of the first flow guiding disc.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0023] A DTRO composite diaphragm for sewage treatment includes a first flow guiding disc 1, second diaphragms 17 are symmetrically installed inside the first flow guiding disc 1, connecting blocks 10 are symmetrically and fixedly connected to the outside of the first flow guiding disc 1, a sliding groove 13 is opened inside the connecting block 10, an adjusting block 14 is slidably connected inside the sliding groove 13, clamping blocks 9 are symmetrically and fixedly connected to the bottom of the adjusting block 14, second flow guiding discs 2 are symmetrically arranged outside the first flow guiding disc 1, fixing grooves 7 for cooperating with the clamping blocks 9 are symmetrically opened inside the second flow guiding discs 2, and a first diaphragm 3 is installed inside the second flow guiding discs 2; during use, the number of diaphragms can be increased through the arrangement of the second flow guiding discs 2 and the first diaphragm 3, thereby enhancing the sewage treatment effect. The movement of the adjusting block 14 drives the clamping blocks 9 to move, so that the clamping blocks 9 move into the fixing grooves 7, thereby installing between the first flow guiding disc 1 and the second flow guiding disc 2.

[0024] Furthermore, connecting rods 15 are symmetrically and slidably connected inside the first flow guiding disc 1, the adjusting block 14 is fixedly connected to the connecting rods 15, a fixing block 11 is fixedly connected to one end of the connecting rod 15 away from the adjusting block 14, and a return spring 16 is sleeved on the outside of the connecting rod 15 and on one side of the adjusting block 14. The movement of the fixing block 11 drives the connecting rod 15 to move, the connecting rod 15 drives the adjusting block 14 to move, and the return spring 16 drives the adjusting block 14 to move back to its original position, thereby assisting in disassembling and assembling between the first flow guiding disc 1 and the second flow guiding disc 2.

[0025] Furthermore, protective grooves 12 are symmetrically formed inside the first flow guiding disc 1. The arrangement of the protective grooves 12 can protect the fixing blocks 11.

[0026] Furthermore, positioning blocks 8 are symmetrically and fixedly connected to the outer side of the first flow guiding disc 1. Positioning grooves 6 that are used in cooperation with the positioning blocks 8 are equidistantly formed inside the second flow guiding disc 2. The arrangement of the positioning blocks 8 and the positioning grooves 6 can achieve a positioning effect when the first flow guiding disc 1 and the second flow guiding disc 2 are installed.

[0027] Furthermore, mounting grooves 5 that are used in cooperation with the connecting blocks 10 are equidistantly formed on one side of the second flow guiding disc 2. The arrangement of the mounting grooves 5 can be used in cooperation with the connecting blocks 10, facilitating the installation between the first flow guiding disc 1 and the second flow guiding disc 2.

[0028] Furthermore, a sealing ring 4 is provided on one side of the second flow guiding disc 2. The arrangement of the sealing ring 4 achieves a sealing effect.

[0029] During use, the arrangement of the second flow guiding disc 2 and the first diaphragm 3 can increase the number of diaphragms, thereby enhancing the sewage treatment effect. When installing between the first flow guiding disc 1 and the second flow guiding disc 2, the connecting block 10 is pushed into the interior of the mounting groove 5. Since one side of the clamping block 9 is beveled, during the process of the connecting block 10 entering the interior of the mounting groove 5, the inner wall of the mounting groove 5 will squeeze and drive the clamping block 9 to slide. The clamping block 9 drives the adjusting block 14 to slide along the sliding groove 13, and the return spring 16 is compressed. When the connecting block 10 completely enters the mounting groove 5, the return spring 16 will drive the adjusting block 14 to move and reset due to the elastic force. The adjusting block 14 drives the clamping block 9 to move into the interior of the fixing groove 7, thereby quickly installing between the first flow guiding disc 1 and the second flow guiding disc 2. When disassembly is required, the fixing block 11 is pulled. The fixing block 11 drives the adjusting block 14 to move through the connecting rod 15. The adjusting block 14 drives the clamping block 9 to move out of the fixing groove 7, and the first flow guiding disc 1 and the second flow guiding disc 2 can be separated, facilitating use.
