the third connecting pipe 70, the third connecting pipe 70 is provided with a cutter 71 and a pump 72, the cutter 71 is used for cutting materials in the third connecting pipe 70, the third connecting pipe 70 is provided with an input end and an output end 74, the pump 72 is used for inputting and outputting fluid in the input end 74, the input end comprises a first input end 731 and a second input end 732, the first input end 731 is connected to the top of the classifying pipe 12, the second input end 732 is connected to the bottom of the second cylinder 21, and the output end 74 is connected to the bottom of the second cylinder 21.
Here, the material in this embodiment refers to kitchen waste, and generally includes slurry, sand, bone, and the like. In other embodiments, any fluid slurry requiring sedimentation separation is also possible.
The material enters the first cylinder 11 from the feed inlet 112, enters the classifying pipe 12 through the guide port, part of the material in the classifying pipe 12 enters the third connecting pipe 70 through the first input end 731, part of the material enters the second cylinder 21 through the first connecting pipe 50, part of the heavy foreign matter deposits enter the bottom of the classifying pipe 12, and is discharged through the first sand discharge port 121.
Meanwhile, part of the material in the second cylinder 21 enters the third connecting pipe 70 through the second input end 732, and part of the material flows back into the classifying pipe 12 through the second connecting pipe 60 for local circulation, so that an upflow effect is formed.
Meanwhile, the material entering the third connecting pipe 70 is cut by the cutter 71, and then is fed into the output end 74 by the pressurization of the pump 72, and the output end 74 is relatively positioned at the bottom of the second cylinder 21, so that multiple cycles are performed.
The slurry eventually reaching the requirements is discharged through the discharge port 211.
Generally, the slurry enters the third connecting tube 70 mainly from the first input end 731, and part of the slurry enters the second cylinder 21 through the first connecting tube 50, which mainly plays a role of overflow protection.
The material enters the first cylinder 11 from the feeding hole 112 in a tangential feeding manner, that is, the first cylinder 11 is cylindrical, and the feeding direction of the material is along the tangential direction, so that the material in the first cylinder 11 is more favorable to be stirred.
Similarly, the first connecting pipe 50 is used for inputting the materials in the second cylinder 21, and the tangential feeding mode can be adopted, so that the materials in the second cylinder 21 can be stirred.

In this way, the material is facilitated to achieve a sedimentation buffer in the second cylinder 21, after it enters the classifying tube 12, the material in the classifying tube 12 is agitated and an upflow effect is formed, which is beneficial to achieving fluidization separation, lighter material floats up, overflow protection is achieved through the first connecting tube 50, heavier material sinks, and is precipitated at the bottom of the classifying tube 12, and finally is discharged through the first sand discharge port 121.
The slurry mainly forms an upward flow in the classifying pipe 12 through the liquid which is circulated and reflowed by the second connecting pipe 60, and lighter materials are in a fluidized state and circulate along with the fluid; heavier materials cannot rise with the fluid and fall to the sand setting port.
Referring to fig. 2 and 3, the classifying tube 12 is provided with a first port 101, a second port 102 and a third port 103, and the second cylinder 21 is provided with a fourth port 201, a fifth port 202 and a sixth port 203.
The first port 101 mates with the first input 731 to effect communication of the sizing tube 12 with the third connecting tube 70.
