[0032] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The utility model provides a high-salt wastewater membrane concentration and reduction device, comprising:

[0033] The box body 1 has a pump body 2 fixedly arranged on the side of the box body 1, a membrane concentration filter 3 is connected to the pump body 2, and a filtering mechanism 4 is provided on the box body 1. It should be noted that the high-salt wastewater after the reaction is filtered by the filtering mechanism 4 to prevent the precipitation from entering the membrane concentration filter 3 through the pump body 2, thereby ensuring the normal operation of the membrane concentration filter 3. The specific structure of the membrane concentration filter 3 is prior art and will not be described in detail here.

[0034] The filter mechanism 4 includes a frame 401, a movable frame 402, a plate 403, a rotating shaft 404, a connecting rod 405, a cylinder 406, a filter cartridge 407, a spring 410 and a round frame 411;

[0035] The frame 401 is fixedly installed on the side of the box body 1, the bottom of the movable frame 402 is fixedly connected to the plate body 403, the rotating shaft 404 is rotatably installed on the plate body 403, the spring 410 is fixedly installed between the movable frame 402 and the side wall of the frame 401, the connecting rod 405 is fixedly installed between the cylinder 406 and the rotating shaft 404, the filter cylinder 407 is clamped with the cylinder 406, and the round frame 411 is fixedly installed on the side wall of the box body 1, and the cylinder 406 is clamped with the round frame 411.

[0036] Through the above-mentioned filtering mechanism 4, the high-salt wastewater after the reaction falls into the filter cartridge 407, and the filter mesh 409 in the filter cartridge 407 filters the sediment. After a period of use, the rotating shaft 404 is pushed upward to move the cylinder 406 out of the circular frame 411, and then the rotating shaft 404 is rotated to switch the positions of the two filter cartridges 407. Then the rotating shaft 404 is released, and the spring 410 drives the movable frame 402 downward due to its own elastic force, so that the cylinder 406 can be stuck in the circular frame 411, and then the used filter cartridge 407 is removed and the sediment in the filter cartridge 407 is poured out. It is more convenient to use.

[0037] Specifically, the filter mechanism 4 also includes a limit block 408, which is fixedly installed on the filter cylinder 407. A limit groove is provided at the top of the cylinder 406, and the limit block 408 is clamped in the limit groove. The filter mechanism 4 also includes a filter screen 409, which is fixedly installed inside the filter cylinder 407. It should be noted that the sediment is filtered.

[0038] Specifically, a square hole is opened on the side of the box body 1, and the end of the connecting rod 405 passes through the square hole. It should be noted that this is convenient for the connecting rod 405 to enter and exit the box body 1.

[0039] Specifically, the movable frame 402 is mounted on the frame 401 in a vertical sliding manner. It should be noted that this facilitates the stable vertical movement of the movable frame 402 .

[0042] Working principle:

[0043] S1: Filter the high-salt wastewater after the reaction through the filtering mechanism 4 to prevent the sediment from entering the membrane concentration filter 3 through the pump body 2, thereby ensuring the normal operation of the membrane concentration filter 3;

[0044] S2: The high-salt wastewater after the reaction falls into the filter cartridge 407. The filter screen 409 in the filter cartridge 407 filters the sediment. After a period of use, the rotating shaft 404 is pushed upward, and the rotating shaft 404 drives the plate 403 to move upward. The plate 403 drives the movable frame 402 to move upward. The movable frame 402 squeezes the spring 410, so that the cylinder 406 can be moved out of the circular frame 411.

[0045] S3: Then rotate the rotating shaft 404 to switch the positions of the two filter cartridges 407, and then release the rotating shaft 404. The spring 410 drives the movable frame 402 downward due to its own elastic force, so that the cylinder 406 can be stuck into the round frame 411. Then remove the used filter cartridge 407 and pour out the sediment in the filter cartridge 407. It is more convenient to use.
