Background
The extruder belongs to one of the types of plastic machines, plastic materials enter the extruder from a hopper and are conveyed forward under the drive of the rotation of a screw, and the materials are heated by a charging barrel, sheared by the screw and compressed in the forward movement process to be melted, so that the change among three states of glass state, high elastic state and viscous state is realized, raw material particles need to be kept in a dry state before entering the extruder, and otherwise the quality of the subsequent process is influenced.
The extruder feed particles need to be baked to reduce the water content prior to production. At present, the traditional drying mode is used for heating air through the heater, and the air-blower is with during hot-air drum goes into the feed cylinder that dries by the fire that is equipped with the raw materials particle, and the air outlet of air-blower connects the exhaust duct, dries by the fire the top of feed cylinder and has seted up the exhaust hole, can discharge the steam that steam carried from drying by the fire the feed cylinder. However, the traditional material drying method can bring out impurities or dust in the raw material particles, and the impurities or dust are blown into the air in a large area, so that pollution is caused; meanwhile, the traditional material drying mode can directly discharge hot air into the air along with water vapor, the heating time and the heating frequency can be increased, and the energy consumption is increased. Therefore, a hot air return system for a particle extruder is urgently needed at present, which can prevent impurities or dust from being blown into the air and can reduce the heating time and times.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the aforesaid not enough, provide one kind and can avoid impurity or dust to raise to the air and can reduce the particle for the extruder hot return air system of length and number of times of heating again.
The purpose of the utility model is realized like this:
a hot air return system for a particle extruder comprises a material drying barrel, wherein the top of the material drying barrel is connected with an air outlet elbow; one end of the air outlet elbow is connected to the material drying barrel, and the other end of the air outlet elbow is connected with a bendable and moldable exhaust pipe; one end of the exhaust pipe is connected with the air outlet elbow, and the other end of the exhaust pipe is connected with the air inlet box; go into bellows one end and connect the exhaust pipe, the air-blower is being connected to the other end that goes into bellows, the air-supply line is being connected to the gas outlet of air-blower, the one end and the air-blower of air-supply line are connected, and the other end of air-supply line is connected on feed hopper, feed hopper's top and the bottom of drying by the fire the storage bucket are fixed continuous.
