[0033] like Figures 1-3 As shown, the extruder 1 includes an extruder body 11. A feed pipe 12 is installed at the feed inlet of the extruder body 11, allowing raw materials to be fed into the extruder body 11 for extrusion. An exhaust pipe 13 is installed at the exhaust outlet of the extruder body 11, through which exhaust gas inside the extruder body 11 is discharged.

[0034] like Figures 2-7As shown, the raw material processing assembly 2 comprises a shell 21 fixedly connected to the feed pipe 12, so that the screened and processed raw material passes through the shell 21 and is added to the extruder body 11 through the feed pipe 12. A screening plate 22 is detachably installed in the shell 21, so that the screening plate 22 is easily detached from the shell 21, and the screening plate 22 is used to screen the raw material entering the shell 21. A plurality of first magnetic attraction rings 25 are fixedly connected to the bottom of the screening plate 22. The raw material screened by the screening plate 22 flows through the first magnetic attraction rings 25, so that the magnetic metal impurities in the raw material are processed by the first magnetic attraction rings 25. A screen 23 is fixedly connected in the shell 21, and the screen 23 is used to screen the raw material screened by the screening plate 22 again. A rotating shaft 28 is rotatably connected to the screen 23, and a first gas conveying groove 29 is formed in the rotating shaft 28. The first gas conveying groove 29 is used to convey the high-temperature tail gas. A plurality of drive impellers 210 are fixedly connected to the side wall of the rotating shaft 28, so that the rotation of the rotating shaft 28 drives the plurality of drive impellers 210 to rotate, so that the drive impellers 210 drive the raw material on the screen 23 to rotate, thereby improving the screening efficiency of the raw material by stirring. A second gas conveying groove 211 is formed in each of the plurality of drive impellers 210, and the second gas conveying groove 211 is in communication with the first gas conveying groove 29, so that the high-temperature tail gas conveyed in the first gas conveying groove 29 can be conveyed into the second gas conveying groove 211. A plurality of nozzles 212 are installed on the side wall of the drive impeller 210, and the tail gas in the second gas conveying groove 211 can be sprayed out through the nozzles 212. The gas supplied to the second gas conveying groove 211 is set to be a gas with a relatively large pressure, so that the gas sprayed out of the nozzles 212 has a relatively large pressure, thereby impacting the drive impeller 210 when the gas is sprayed out of the nozzles 212, so that the drive impeller 210 drives the rotating shaft 28 to rotate, so that the sprayed gas drives the rotation of the rotating shaft 28 to stir the raw material, and the high-temperature gas can contact the raw material, thereby achieving the functions of re-drying the raw material and preheating the raw material entering the extruder body 11, thereby ensuring that the raw material entering the extruder body 11 is dry.

[0035] Optionally, the screening plate 22 is easily detachable, so that the screening plate 22 is easily replaced. In specific use, the screening plate 22 can be replaced according to the particle size requirements of the extruder for the raw material, and when the raw material extruded by the extruder itself has magnetism, the screening plate 22 is replaced by one without the first magnetic attraction ring 25 installed at the bottom, thereby avoiding the first magnetic attraction ring 25 from attracting the raw material.

A plurality of second air inlet holes 215 matched with the first air inlet holes 213 are formed in the side wall of the inner ring 214, so that the high-temperature tail gas can enter the first gas conveying groove 29 through the second air inlet holes 215 and the first air inlet holes 213, and the rotation of the rotating shaft 28 will drive the inner ring 214 to rotate.

[0040] As shown in the drawings, Figures 5-7 The outer side of the inner ring 214 is rotatably connected with an outer ring 216 in a sealed manner, and a third air inlet hole 217 is formed in the side wall of the outer ring 216.

Through the second gas conveying pipe 15, the high-temperature tail gas can be conveyed into the second air inlet hole 215 through the third air inlet hole 217, so as to realize the conveying of the high-temperature tail gas into the first gas conveying groove 29. Since the outer ring 216 and the inner ring 214 can rotate relative to each other, when the inner ring 214 rotates with the rotating shaft 28, the outer ring 216 can be in a fixed state, thereby ensuring the firm connection between the second gas conveying pipe 15 and the outer ring 216, and realizing the conveying of the tail gas.
