[0044] Embodiment 2

[0045] A treatment method for a filtration treatment device for aquaculture wastewater, including a treatment method for a filtration treatment device for aquaculture wastewater, the treatment method is as follows:

[0046] 1) Aquaculture wastewater enters the treatment box 1 from the water inlet pipe and then enters one of the installation cylinders 2. After being filtered by the filter body 41 on the installation cylinder 2, the wastewater is discharged from the waste outlet at the bottom thereof;

[0047] 2) When one of the filter bodies 41 needs to be replaced, firstly, the two installation cylinders 2 are driven by the rotating assembly 3 to rotate 180 degrees to replace the positions of the two filter bodies 41;

[0048] 3) When automatically cleaning the used filter body 41, first open the filter mounting plate 4 through the auxiliary mechanism 5, and the impurities on the filter body 41 are discharged from the waste outlet at the bottom along the opened inclined surface. At the same time, connect the water spray pipe 7 to the external water source, and the water source is sprayed on the inner wall of the installation cylinder 2 through the water spray pipe 7. Then start the automatic cleaning mechanism 6 to make the cleaning plate 1 604 and the cleaning plate 2 605 enter the installation cylinder 2, and the cleaning plate 1 604 and the cleaning plate 2 605 are in contact with the inner wall of the installation cylinder 2 and the filter body 41 respectively, and automatically clean the installation cylinder 2 by rotating in combination with the water source.

[0049] In summary, the aquaculture wastewater filtering and treatment device and treatment method, through the rotating component 3, that is, the motor 301 fixedly installed at the bottom of the treatment box 1 drives the rotating rod 302 connected to the two mounting cylinders 2 to rotate, so that the two mounting cylinders 2 can be synchronously rotated one hundred and eighty degrees, and the positions of the two filter bodies 41 can be quickly replaced. When the filter body 41 needs to be replaced, there is no need to stop the equipment for a long time for complicated disassembly and installation, which greatly improves the speed of filter replacement, realizes rapid and seamless connection, ensures the continuity of wastewater filtration work, and thus improves the overall treatment efficiency.

[0050] Furthermore, the electric push rod 502 in the auxiliary mechanism 5 pushes the slider 504 to slide in the slide groove 503, which can drive the filter installation plate 4 to rotate and open around the hinge point at the bottom of the installation cylinder 2, so that the impurities on the filter body 41 are discharged from the bottom waste outlet along the opened inclined surface. There is no need to completely disassemble the filter body 41 from the device for cleaning, which saves cleaning time. At the same time, in conjunction with the automatic cleaning mechanism 6, after opening the filter installation plate 4, the water spray pipe 7 is connected to the external water source, and the hydraulic cylinder 601 is started to make the motor 2 602, the connecting rod 603, the cleaning plate 1 604 and the cleaning plate 2 605 descend into the installation cylinder 2, and then the motor 2 602 is started to drive them to rotate. In combination with the water source, the installation cylinder 2 and the filter body 41 can be automatically cleaned, which further improves the cleaning efficiency. In addition, the entire cleaning process does not require too much manual intervention and is easy to operate.

[0051] Moreover, the easy-to-disassemble component 42 drives the locking rod 404 to cooperate with the locking hole on the filter body 41 by rotating the movable disk 401 installed inside the filter mounting disk 4, and the sliding rod 403 slidingly installed in the internal oblique arc groove 402 drives the locking rod 404 to cooperate with the locking hole on the filter body 41, as well as the interaction between the fixing block 406, the screw 407, the latch tooth 408 and the convex tooth 405. When the filter body 41 needs to be disassembled, it is only necessary to rotate the screw 407 to separate the latch tooth 408 from the convex tooth 405, and rotate the movable disk 401 to disengage the locking rod 404 from the locking hole of the filter body 41, thereby realizing convenient disassembly and facilitating the replacement of the filter body 41 or more in-depth cleaning and maintenance, which is beneficial to extending the service life of the filter body 41 and ensuring the filtering effect.
