[0004] The technical solution adopted by this utility model is as follows: This utility model proposes a composite high-efficiency and low-energy-consumption screw granulation extruder, including an equipment base, a support pad, a high-efficiency extrusion structure, a production environment control structure, and a drive structure.

The high-efficiency extrusion structure includes an extruder, a feed inlet, a drive shaft, a twin-screw feeder, a single-screw compression pre-plasticizer, a planetary screw energy-saving plasticizer, a single-screw pusher, and an exhaust port. The extruder is fixedly disposed on the equipment base, the feed inlet is disposed on the extruder, the drive shaft is rotatably disposed through the extruder, the twin-screw feeder is disposed on the extruder, the single-screw compression pre-plasticizer is disposed on the extruder, the planetary screw energy-saving plasticizer is disposed on the extruder, the single-screw pusher is disposed on the extruder, and the exhaust port is disposed through the single-screw pusher.

[0005] Preferably, the production environment control structure includes an electric heater, an oil-water separator, a vacuum pump, and a water-cooled cooler. The electric heater is fixedly wrapped around the outside of the extrusion pipe of the extruder and fixedly mounted on the equipment base. The oil-water separator is fixedly mounted on the equipment base and connected to the extrusion pipe of the extruder. The vacuum pump is fixedly mounted on the equipment base and connected to the extrusion pipe of the extruder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 and Figure 2 As shown, this utility model proposes a composite high-efficiency and low-energy-consumption screw granulation extruder, including an equipment base 1, a support pad 2, a high-efficiency extrusion structure 3, a production environment control structure 4, and a drive structure 5. The support pad 2 is mounted on the equipment base 1, the high-efficiency extrusion structure 3 is mounted on the equipment base 1, the production environment control structure 4 is mounted on the equipment base 1, and the drive structure 5 is mounted on the equipment base 1. The high-efficiency extrusion structure 3 includes an extruder 6, a feed inlet 7, a drive shaft 8, a twin-screw feeder 9, a single-screw compression pre-plasticizer 10, a planetary screw energy-saving plasticizer 11, a single-screw pusher 12, and an exhaust port 13. The extruder 6 is fixedly mounted on the equipment base 1, the feed inlet 7 is located on the extruder 6, and the drive shaft 8 passes through the extruder. The machine 6 is rotated. The twin-screw feeder 9 is located on the extruder 6. The single-screw compression pre-plasticizer 10 is located on the extruder 6. The twin-screw feeder 9 is located between the single-screw compression pre-plasticizer 10 and the feed port 7. The planetary screw energy-saving plasticizer 11 is located on the extruder 6. The single-screw pusher 12 is located on the extruder 6. The drive shaft 8 synchronously drives the twin-screw feeder 9, the single-screw compression pre-plasticizer 10, the planetary screw energy-saving plasticizer 11, and the single-screw pusher 12 to work. The exhaust port 13 is set through the single-screw pusher 12. The exhaust port 13 completely covers the working parts of the single-screw compression pre-plasticizer 10, the planetary screw energy-saving plasticizer 11, and the single-screw pusher 12 at the front end of the extruder 6.

[0017] like Figure 1 and Figure 2 As shown, the production environment control structure 4 includes an electric heater 14, an oil-water separator 15, a vacuum pump 16, and a water-cooled cooler 17. The electric heater 14 is fixedly wrapped around the outside of the extrusion pipe of the extruder 6 and fixedly mounted on the equipment base 1. The oil-water separator 15 is fixedly mounted on the equipment base 1 and connected to the extrusion pipe of the extruder 6. The vacuum pump 16 is fixedly mounted on the equipment base 1 and connected to the extrusion pipe of the extruder 6. The water-cooled cooler 17 is fixedly mounted on the equipment base 1 and fixedly mounted at the twin screw feeder 9 on the extruder 6.

[0018] like Figure 1 and Figure 2 As shown, the drive structure 5 includes a gearbox 18, a drive motor 19, and a coupling 20. The gearbox 18 is fixedly mounted on the equipment base 1 and is axially connected to the extruder 6. The drive motor 19 is fixedly mounted on the equipment base 1, and the coupling 20 is fixedly connected between the drive motor 19 and the gearbox 18.

[0019] In practical use, when using this device, the user should first debug the machine, set the heating temperature of the electric heater 14, the cooling temperature of the water-cooled cooler 17, and the vacuum pump 16 vacuum efficiency. Then, start the drive motor 19 to drive the reduction gearbox 18 to rotate through the coupling 20. After the reduction gearbox 18 changes speed, it drives the extruder 6 to rotate and extrude. At this time, the drive shaft 8 inside the extruder 6 rotates, thereby driving the twin-screw feeder 9, the single-screw compression pre-plasticizer 10, the planetary screw energy-saving plasticizer 11, and the single-screw pusher 12 to work. Then, the raw material is passed through... The material is fed into the extruder 6 through the feed port 7. At this time, the twin-screw feeder 9 increases the feed rate through the twin screws. Then, the single-screw compression pre-plasticizer 10 performs plasticization to improve the plasticization efficiency of the subsequent planetary screw energy-saving plasticizer 11 and avoid waste. After plasticization is completed by the planetary screw energy-saving plasticizer 11, the exhaust gas generated by the extrusion is discharged through the exhaust port 13 by the single-screw pusher 12. At the same time, the single-screw pusher 12 pushes the plasticized product out of the extruder, thereby reducing energy consumption and increasing production. The above is the entire process of using the composite high-efficiency low-energy consumption screw granulating extruder 6.
