One side of the rotating shaft 8 penetrates the first filter bin 2 and the second filter bin 3 respectively. The filter chamber 2, the second filter chamber 3 and the wall of one side of the frame 1, one side of the rotating shaft 8 located inside the first filter chamber 2 is connected with a first synchronous wheel 10, one side of the frame 1 is provided with a second synchronous wheel 11, one side of the frame 1 is provided with a driving motor 12, the driving end of the driving motor 12 is connected to the first synchronous wheel 10, the first synchronous wheel 10 and the second synchronous wheel 11 are connected through a synchronous belt 13, one side of the rotating shaft 8 located inside the second filter chamber 3 is connected to one side of the second synchronous wheel 11 through a gear, and a circle of cleaning components is connected to the outside of the rotating shaft 8.

[0034] The cleaning assembly includes a connecting frame 18 connected to the rotating shaft 8, the front side of the connecting frame 18 is evenly provided with grooves, both sides of the grooves are provided with embedded grooves, the front side of the groove is plugged with a socket 19, both sides of the socket 19 are plugged with the embedded grooves, and the two sides of the socket 19 are connected to the embedded grooves by bolts.

[0035] A fixing frame 20 is arranged on the upper side of the plug socket 19 , and notches 21 are evenly formed on the front side of the upper side of the fixing frame 20 , and rubber balls 22 are evenly embedded on the inner walls on both sides of the notches 21 .

[0036] The feed hopper 4 is connected to the first filter bin 2 and is provided with a first discharge port 14, the first discharge port 14 is connected to the inside of the filter cartridge 7, a second discharge port 15 is provided at the connection between the first filter bin 2 and the crushing assembly, the filter cartridge 7 located inside the first filter bin 2 is provided with openings corresponding to the first discharge port 14 and the second discharge port 15 on the upper and lower sides, the crushing assembly and the second filter bin 3 are provided with a third discharge port 16, the second filter bin 3 is provided with a fourth discharge port 17 on the lower side, and the filter cartridge 7 located inside the second filter bin 3 is provided with openings corresponding to the third discharge port 16 and the fourth discharge port 17 on the upper and lower sides.

[0037] The crushing assembly includes a crushing bin 23 arranged between the first filter bin 2 and the second filter bin 3, a crushing shaft 24 extending up and down is arranged inside the crushing bin 23, and a plurality of stirring blades 25 are arranged on the crushing shaft 24 from top to bottom. A stirring motor is installed inside the crushing bin 23 through a frame, and the driving end of the stirring motor is connected to the lower side of the crushing shaft 24. The upper end of the crushing shaft 24 extends into the second discharge port 15, and an inclined rod 26 arranged downward in an octagonal shape is arranged on the extension portion.

[0038] The aquaculture wastewater enters the feed hopper 4, and the crushing motor 5 is controlled to run at the same time. Through the cooperation of two mutually meshing gears, the two crushing rollers 6 can be driven to rotate relative to each other, so that the feces and residues can be crushed to prevent large pieces of debris from entering the device and causing blockage of the device. Subsequently, the crushed feces and wastewater enter the first filter bin 2 through the first discharge port 14. At this time, the driving motor 12 is running and the spiral blade 9 is driven to rotate through the rotating shaft 8. The filter cartridge 7 can be used to squeeze and filter the feces entering the first filter bin 2. Since the filter cartridge 7 is porous as a whole, the feces contain feathers dropped by poultry. For this reason, during the extrusion filtration process, feathers are likely to clog the filter cartridge 7, which will affect the filtration process. During the rotation of the rotating shaft 8, the connecting frame 18 will drive the socket 19 and the fixing frame 20 to move. The front side of the fixing frame 20 is provided with multiple groups of notches 21, and rubber balls 22 are evenly arranged inside the notches 21. During the extrusion filtration process, the upper side of the fixing frame 20 can be used to continuously scrape the inner wall of the filter cartridge 7, and the rubber balls 22 inside the notches 21 rub against the feathers. The friction force can be used to scrape off the feathers inserted in the filter cartridge 7, thereby achieving the purpose of cleaning the feathers on the inner wall of the filter cartridge 7 during the extrusion filtration process, thereby increasing the filtration effect.

[0039] Subsequently, the filtered feces will enter the crushing bin 23 through the second discharge port 15. At the same time, the stirring motor 25 is running, which can drive the crushing shaft 24 and the inclined rod 26 to rotate, wherein the inclined rod 26 is used to prevent the second discharge port 15 from being blocked. The crushing shaft 24 can break up the feces agglomerated after extrusion again. At this time, the hot layer is running, which can increase the looseness of the feces, making it easier for the feces to enter the second filter bin 3 and then be squeezed again.

[0040] Then the residue enters the second filter chamber 3 through the third discharge port 16, and the driving motor 12 continues to run, and through the cooperation of the first synchronous wheel 10, the second synchronous wheel 11, the synchronous belt 13 and the gears, the rotating shaft 8 and the spiral blade 9 located inside the second filter chamber 3 can be driven to rotate in the opposite direction to the rotating shaft 8 inside the first filter chamber 2, and the feces can be squeezed again. After the final squeezing is completed, the feces is discharged through the fourth discharge port 17 and collected by the collecting trough 30, wherein the lower side of the first filter chamber 2 and the second filter chamber 3 are provided with a drain pipe 28, which can discharge the separated liquid in cooperation with the guide groove.

[0041] Inclined guide plates 29 are alternately arranged on the inner walls of both sides of the feed hopper 4, which can slow down the speed at which feces enter the first filter chamber 2 and prevent the feed hopper 4 from being blocked due to excessive feeding of feces.

[0042] The notch 21 is configured as an eight-shaped notch as a whole, which can increase the contact area between the feathers that clog the filter cartridge 7 and the rubber ball 22, making it easier to clean the feathers.

[0043] A control box 31 is provided on the upper side of the second filter chamber 3 to facilitate control of the entire device.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
