For achieving the above object, the utility model provides following technical scheme:
A kind of low-carbon high-efficiency plastic extruder, comprise frame, extruder and air filter, described frame is provided with extruder, described extruder comprises hopper, barrel and screw rod, the middle part of described hopper and bottom are separately installed with vibrations screen pack, the bottom of hopper is communicated with barrel, described screw rod is located in barrel and one end of screw rod and is connected with the drive unit be arranged in frame, the port of export of described barrel is provided with head, the middle part of barrel has steam vent, and described barrel and screw rod are equipped with the gradually little frustum of a cone section of internal diameter near one end of head; Described air filter comprises aspiration pump, blast pipe and settling tank, and the air inlet of aspiration pump is positioned at the top of steam vent, and the air inlet of aspiration pump is set to inverted horn-like, and one end of blast pipe is connected with aspiration pump, and the other end is inserted in settling tank.
As further program of the utility model: described material tube inner wall is provided with heater, the junction of barrel and steam vent is provided with filter screen.
As the utility model further scheme: described vibrations screen pack is stainless steel filter screen and filter opening is circular hole, the vibrations screen pack filter opening area of the filter opening area ratio feed hopper bottom of the vibrations screen pack in the middle part of hopper is large.
As the utility model further scheme: the bus of described frustum of a cone section and the angle of pitch line are 3 °.The length of frustum of a cone section is 40cm, and the distance between frustum of a cone section and hopper is 30cm.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by arranging vibrations screen pack at the middle part of hopper and bottom, can carry out screening and filtering to the impurity of raw material in advance, improve material quality; Screw rod and barrel are provided with frustum of a cone section, and internal diameter from large to small, adds the extrusion pressure of raw material, are convenient to raw material and better carry out plasticizing mixing, improve product quality; The pernicious gas that air filter can effectively produce in processing production process, collects the pernicious gas of discharging at steam vent place by aspiration pump, then to be passed into by pernicious gas through blast pipe and be equipped with in the settling tank of flocculant, low-carbon emission reduction.
