Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figure 1-Figure 11 The present invention provides a water treatment device, comprising:

[0044] The shell 1 has a base 2 and a top cover 3 in its inner cavity, a cylindrical water treatment membrane 4 is arranged between the base 2 and the top cover 3, a drainage cavity is formed between the water treatment membrane 4 and the base 2 and the top cover 3, and a water inlet cavity is formed between the shell 1 and the water treatment membrane 4;

[0045] An air blowing ring 5 is slidably arranged in the drainage cavity through a first transmission assembly, and the air blowing ring 5 abuts against the inner wall of the water treatment membrane 4;

[0046] A dust suction ring 6 is slidably arranged in the water inlet cavity through a second transmission assembly, and the dust suction ring 6 abuts against the outer wall of the water treatment membrane 4;

[0047] A motor 7, which is arranged on the outer wall of the housing 1, and the motor 7 is in transmission cooperation with the first transmission assembly and the second transmission assembly;

[0048] A blast device 8 is arranged on the outer wall of the housing 1 and is connected to the blowing ring 5;

[0049] The dust suction device 9 is arranged on the outer wall of the shell 1 , and the dust suction device 9 is connected with the dust suction ring 6 .

[0050] The aquaculture tail water in the water inlet cavity can be filtered and treated through the water treatment membrane 4 in the shell 1 and then discharged through the drainage cavity. When the water treatment membrane 4 needs to be cleaned and maintained, it is only necessary to start the blowing device 8 and the dust suction device 9, and the motor 7 drives the first transmission assembly and the second transmission assembly, so that the blowing ring 5 and the dust suction ring 6 move back and forth along the inner and outer walls of the water treatment membrane 4, and the impurities on the water treatment membrane 4 are blown toward the dust suction ring 6 through the blowing ring 5. At the same time, the dust suction ring 6 absorbs the impurities through the suction force generated by the dust suction device 9, thereby realizing the cleaning of the water treatment membrane 4 without disassembling the water treatment membrane 4.

[0051] Furthermore, the positions of the air blowing ring 5 and the dust suction ring 6 correspond synchronously, thereby improving the cleaning effect.

[0052] A further optimized solution is that the first transmission assembly includes a first screw rod 10 and a first guide rod 11. The first screw rod 10 is rotatably connected to the base 2.

The spur gear 19 is sleeved on the vertical pole 20, and a slider slidably fitted in the spiral groove is fixedly connected to the spur gear 19.

[0058] When the second nut 17 drives the support ring body 61 to move, the support ring body 61 drives the spur gear 19 to slide along the vertical rod 20, so that the slider on the spur gear 19 slides along the spiral groove on the vertical rod 20, so that the spur gear 19 rotates, thereby driving the ring gear 65 to rotate through the spur gear 19, and then driving the rotating ring body 62 to rotate through the ring gear 65, so that the multiple dust nozzles 64 are lifted and rotated along the water treatment membrane 4, and the spring 63 pushes the dust nozzle 64 to keep against the water treatment membrane 4, thereby improving the dust suction and cleaning effect on the water treatment membrane 4.

[0059] A further optimized solution is that an air cavity 66 is opened circumferentially in the rotating ring body 62, and a sealing ring 67 is slidably fitted on the top surface of the air cavity 66.
