The cross-sectional area of ​​the second feed port 105 gradually decreases from top to bottom, so that the material flows in a conical shape when flowing through the gradually shrinking second feed port 105. The conical feed port can reduce the dead angle formed by the material at the feed port, reduce the phenomenon of material jamming and retention, and improve the recovery efficiency. A conveying mechanism for conveying the furfural waste residue is fixedly connected to the bottom of the second feed port 105, and a separation device for recovering the furfural waste residue is arranged on the side of the conveying mechanism.

[0023] In this embodiment, the conveying mechanism includes a conveying cylinder 2, a rotating motor 201, and a conveying blade 202. The conveying blade 202 is spiral-shaped. The spiral-shaped conveying blade 202 can better distribute pressure when bearing load, thereby improving stability and wear resistance. The conveying cylinder 2 is provided with a second feed port 105 at the bottom and is connected to the second feed port 105. The rotating motor 201 is provided on the side of the conveying cylinder 2 away from the separation device. The output end of the rotating motor 201 is fixedly connected with a rotating shaft 203. The rotating shaft 203 passes through the side of the conveying cylinder 2 and is fixedly connected to the conveying blade 202. When the rotating motor 201 is started, the rotating motor 201 will drive the rotating shaft 203 and the conveying blade 202 to rotate, and the conveying blade 202 will generate a propulsion force. When the furfural waste residue enters from the second feed port 105, the conveying blade 202 will send the furfural waste residue into the separation device for separation.

[0024] In this embodiment, the separation device includes a separation box 3, a telescopic drive mechanism 301, and an extrusion box 302. The telescopic drive mechanism 301 adopts a cylinder.

The telescopic drive mechanism 301 is arranged on the side of the separation box 3, and the telescopic rod of the telescopic drive mechanism 301 is fixedly connected with an extrusion plate 304. The end of the extrusion plate 304 away from the telescopic drive is serrated, which can increase the friction between the extrusion surface and the furfural waste residue and improve the extrusion efficiency. The extrusion plate 304 is arranged inside the extrusion box 302 and is slidably connected to the inner wall of the extrusion box 302. A plurality of drainage ports 305 are arranged around the separation box 3, a second discharge port 7 is arranged at the bottom of the separation box 3, and a collecting box 701 is arranged at the bottom of the second discharge port 7. When the telescopic driving mechanism 301 repeatedly squeezes the furfural waste residue, the moisture in the furfural waste residue will be squeezed out, and the moisture will flow out of the squeezing box 302 through the drainage port 305, and flow into the collecting box 701 through the second discharge port 7 flow channel, thereby realizing dry-wet separation. If the squeezed-out moisture is not obviously polluted, it can be reused after simple treatment, and can be used for irrigating crops, cooling equipment or as circulating water in the production process, etc., while the solid matter can be used to make fertilizers, fuels, etc., thereby improving the comprehensive utilization value of the waste residue.

The rubber sleeve 602 can increase the friction and grip of the operator's hand, so that the handle 601 is not easy to slide, thereby improving the safety of the operator. When the separation device stops running, the staff holds the handle 601 and opens the box door 6 to take out the solid matter in the extrusion box 302 for making fertilizer, thereby improving the utilization value of the furfural waste residue.

[0028] Working principle: When the furfural processing box 1 is running, the rotating motor 201 and the telescopic drive mechanism 301 are started, and the generated waste residue will flow into the second feed port 105 through the opening and closing door 103, and be transported to the inside of the separation box 3 through the conveying blades 202.
