When filtering water, the filter plate 11 can be placed on the top of the fixed rod 8 first, and then the filter plate 11 can be fixed on the top of the fixed rod 8 through the action of the threaded cap 13, and then the transmission motor 5 can be operated, thereby driving the first gear 7 to rotate, and then driving the filter plate 11 to make a circular motion around the fixed rod 8. When the filter plate 11 rotates, the impurities deposited on the surface of the filter plate 11 are cleaned through the cooperation between the fixed plate 14 and the brush 15. When it is necessary to filter the water for shrimp and crab farming, this step can increase the filtration area through the rotation of the filter plate 11, and then the impurities at the bottom of the filter plate 11 are cleaned through the brush 15, thereby improving the filtration efficiency of the filter plate 11 for shrimp and crab farming water. At the same time, through the cleaning action of the brush 15, the possibility of clogging at the bottom of the filter plate 11 can be further reduced. By timely cleaning to prevent clogging, the service life of the equipment can be extended, the number of maintenance and cleaning times can be reduced, and the operating cost can be reduced.

[0026] like Figure 2-4 As shown, a water inlet pipe 16 is slidably connected to the inside of one side of the box body 1; a plurality of water pipe cavities 17 are provided on the outside of the water inlet pipe 16; a spring placement cavity 18 is provided at a position corresponding to the water pipe cavity 17 inside one side of the box body 1; a telescopic spring 19 is fixedly connected to the inside of the spring placement cavity 18, and a limiting steel ball 20 is fixedly connected to the bottom end of the telescopic spring 19; during operation, the water inlet pipe 16 can be pulled so that the limiting steel ball 20 is squeezed toward the telescopic spring 19, and the telescopic spring 19 will be compressed, and then the restraining effect on the water inlet pipe 16 will be released, so that the water inlet pipe 16 can slide in the box body 1. When it is necessary to disassemble the filter plate 11 to move the water inlet pipe 16, this step reduces the cumbersome disassembly and assembly process, reduces the manpower investment and time consumption, and at the same time, due to the reduction in the number of disassembly times, it also further reduces the risk of component damage or loss, and improves the reliability and stability of the equipment.

[0027] like Figure 5-6 As shown, a plurality of first fixed shafts 21 are fixedly connected to the inner ends of the box body 1; a biochemical filter box 22 is slidably connected above the first fixed shaft 21; a biochemical filter cavity 23 is provided inside the biochemical filter box 22; a biochemical filter hole 24 is provided at the bottom of the biochemical filter box 22; when working, after the aquaculture water reaches the inside of the biochemical filter box 22 after physical filtration, it is filtered by the biochemical filter material in the biochemical filter cavity 23, and then flows downward through the biochemical filter hole 24. This step converts organic pollutants in the water into inorganic substances and removes harmful substances through the attachment and metabolism of microorganisms, and at the same time, it can also increase the dissolved oxygen content in the water, further playing a role in purifying the water quality.

[0028] like Figure 5-6 As shown, a plurality of second fixed shafts 25 are fixedly connected to the inner ends of the box body 1 at positions away from the first fixed shaft 21; a chemical filter box 26 is slidably connected above the second fixed shaft 25; a chemical filter cavity 27 is provided inside the chemical filter box 26; a chemical filter hole 28 is provided at the bottom of the chemical filter box 26; when working, after the aquaculture water after biochemical filtration reaches the inside of the chemical filter box 26, it is filtered by the chemical filter material in the chemical filter box 26, and then flows downward through the chemical filter hole 28. This step absorbs residual drugs and other harmful substances through chemical reactions to keep the water quality clean and stable.

[0029] like Figure 5-6 As shown, a water pump 29 is fixedly connected to the bottom of the box body 1; the water outlet of the water pump 29 is connected to a water outlet pipe 30; during operation, when it is necessary to discharge the filtered water out of the device, the water pump 29 is started to send the water into the water outlet pipe 30 for discharge. This step effectively reduces the resistance of the fluid through the action of the water pump 29, thereby improving the transportation efficiency.

[0030] like Figure 1 As shown, the top of the box body 1 is rotatably connected with a box cover 2; when the device needs to be managed during operation, the box cover 2 is lifted to control the opening and closing of the device. In this step, the box body 1 can be sealed by the box cover 2, effectively reducing the secondary pollution of the outside air to the inside of the device, and facilitating the opening and closing of the device.

[0031] like Figure 1 As shown, a movable pulley 31 is fixedly connected to the bottom end of the box body 1; when working, the movable pulley 31 is rotated to push the device to move. This step reduces the need for manual handling or pushing of the device and reduces the labor intensity of workers.

[0032] Working principle: during operation, when it is necessary to filter the water for shrimp and crab breeding, the filter plate 11 can be placed on the top of the fixed rod 8, and then the filter plate 11 can be fixed on the top of the fixed rod 8 through the action of the threaded cap 13, and then the transmission motor 5 can be operated, thereby driving the first gear 7 to rotate, and then driving the filter plate 11 to make a circular motion around the fixed rod 8. When the filter plate 11 rotates, the impurities deposited on the surface of the filter plate 11 are cleaned through the cooperation between the fixed plate 14 and the brush 15. In this step, when it is necessary to filter the water for shrimp and crab breeding, the filter plate 11 can be rotated to increase the filtering area, and then the impurities at the bottom of the filter plate 11 can be cleaned through the brush 15, thereby The filtering efficiency of the filter plate 11 for shrimp and crab breeding water can be improved. At the same time, the cleaning effect of the brush 15 can further reduce the possibility of clogging at the bottom of the filter plate 11. By timely cleaning to prevent clogging, the service life of the equipment can be extended, the number of maintenance and cleaning times can be reduced, and the operating cost can be reduced. The water inlet pipe 16 can be pulled so that the limiting steel ball 20 is squeezed toward the telescopic spring 19, and the telescopic spring 19 will be compressed, and then the restraining effect on the water inlet pipe 16 is released, so that the water inlet pipe 16 slides in the box body 1. When the filter plate 11 needs to be disassembled and the water inlet pipe 16 needs to be moved, the structure of the telescopic spring 19 and the limiting steel ball 20 cooperates to reduce the cumbersome disassembly and assembly process, and reduce the manpower investment and time. At the same time, since the number of disassembly times is reduced, the risk of component damage or loss is further reduced, and the reliability and stability of the equipment are improved. After the aquaculture water after physical filtration reaches the inside of the biochemical filter box 22, it is filtered by the biochemical filter material in the biochemical filter cavity 23, and then flows downward through the biochemical filter hole 24. This step converts organic pollutants in the water into inorganic substances through the attachment and metabolism of microorganisms, removes harmful substances, and can also increase the dissolved oxygen content in the water, further playing a role in purifying water quality. After the aquaculture water after biochemical filtration reaches the inside of the chemical filter box 26, it is filtered by the chemical filter material in the chemical filter box 26, and then flows through the chemical filter hole 28. Towards the bottom, this step absorbs residual drugs and other harmful substances through chemical reactions to keep the water clean and stable. When the filtered water needs to be discharged from the device, the water is sent to the outlet pipe 30 for discharge by starting the water pump 29. This step effectively reduces the resistance of the fluid through the action of the water pump 29, thereby improving the transportation efficiency. When the equipment needs to be managed, the opening and closing of the equipment is controlled by lifting the box cover 2. This step can seal the box body 1 through the action of the box cover 2, effectively reducing the secondary pollution of the outside air to the inside of the equipment, and facilitating the opening and closing of the equipment. The equipment is pushed to move by the rotation of the moving pulley 31. This step reduces the need for manual handling or pushing of the equipment and reduces the labor intensity of the workers.
