The filter box 118 performs a second layer of filtration on the water. After the second filter plate 1221 is used for a long time, the box door 123 is opened, and the motor 119 is started by an external power supply. The motor 119 drives the second threaded rod 120 to rotate, so that the cleaning bar 121 slides on the outer surface of the second threaded rod 120, and at the same time, the cleaning bar 121 limits the cleaning bar 121 when it slides.

The interior of the filter box 118 is fixedly connected to the second filter plate 1221. The box door 123 is opened, and the motor 119 is started by an external power supply. The motor 119 drives the second threaded rod 120 to rotate, so that the cleaning strip 121 slides on the outer surface of the second threaded rod 120. At the same time, the limiting rod 122 limits the cleaning strip 121 when it slides. When the cleaning strip 121 slides on the upper surface of the second filter plate 1221, its upper surface can be cleaned, saving manpower.

As shown in Figures 1-8, in one embodiment, the cleaning strip 121 is slidably connected to the top of the outer surface of the limiting rod 122, the outer surface of the filter box 118 is fixedly embedded with a fourth water pipe 124, and the sedimentation tank 125 is arranged directly below one end of the fourth water pipe 124. The water enters the fourth water pipe 124 after being filtered by the second filter plate 1221, and enters the interior of the sedimentation tank 125 through the fourth water pipe 124. The lifting plate 126 is then attached to the bottom of the inner wall of the sedimentation tank 125, and the water outlet of the L-shaped pipe 129 can be blocked. The electric push rods 128 around it are started by an external power supply to push the lifting plate 126 up.

Working principle: When in use, turn the valve 103 so that the water inside the breeding pond 101 enters the upper surface of the first filter plate 110 through the first water pipe 102, and the water inside the breeding pond 101 is filtered through the first filter plate 110. Impurities remain on the upper surface of the first filter plate 110, and the water enters the interior of the reservoir 105. Turn the first threaded rod 107 to move the movable U-shaped block 109 to one side under the limit of the telescopic rod 108. After the movement, the movable U-shaped block 109 is detached from the surface of the first filter plate 110, and the first filter plate 110 can be removed from above the movable U-shaped block 109 and the fixed U-shaped block 111, and the impurities on the upper surface of the first filter plate 110 can be cleaned and continued to be used to avoid excessive accumulation of impurities on the upper surface of the first filter plate 110, which will cause the first filter plate 110 to be unable to be used normally. Before the water in the water reservoir 105 enters the second water pipe 114 through the hollow pipe 112, a circular filter 113 is arranged inside the hollow pipe 112, which can isolate the water impurities in the water reservoir 105 to the outer surface of the circular filter 113 to prevent the second water pipe 114 from being blocked. At the same time, the hollow pipe 112 can be disassembled to clean out the impurities in the circular filter 113. The hollow pipe 112 is connected to the outer surface of the water reservoir 105 through a flange, and the water pump 115 is started to pump the water in the water reservoir 105 through the second water pipe 114 and the hollow pipe 112. 05 The water inside is pumped out to the inside of the filter box 118, and the filter box 118 performs a second layer of filtration on the water.

The motor 119 drives the second threaded rod 120 to rotate, so that the cleaning bar 121 slides on the outer surface of the second threaded rod 120. At the same time, the limit rod 122 limits the cleaning bar 121 when it slides. When the cleaning bar 121 slides on the upper surface of the second filter plate 1221, its upper surface can be cleaned, saving manpower. The water enters the fourth water pipe 124 after being filtered by the second filter plate 1221, and then enters the interior of the sedimentation tank 125 through the fourth water pipe 124. The lifting plate 126 is now attached to the bottom of the inner wall of the sedimentation tank 125, and the water outlet of the L-shaped pipe 129 can be blocked.
