As the utility model further scheme: described second screw flight is blade type.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging the second screw rod in feed hopper bottom, can in advance to raw material bulky grain thing shear, the particle diminished after pretreatment more easily carries out plastifying, mixing, and improves production efficiency and product quality; Barrel inside is provided with shearing screw thread, and screw rod and barrel are provided with internal diameter frustum of a cone section from large to small, add the shearing force to raw material and extrusion pressure, improve product quality further; Air filter collects the pernicious gas of steam vent and head section discharge by aspiration pump, then being passed into by pernicious gas through blast pipe is equipped with in the settling tank of flocculant, not only have collected steam and the pernicious gas at steam vent place, effectively can also collect the pernicious gas at head place, low-carbon emission reduction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of barrel portion in the utility model.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-2, a kind of low-carbon high-efficiency plastic extruder of improvement, comprise the low-carbon high-efficiency plastic extruder of improvement, comprise frame 1, extruder 2 and air filter 3, described frame 1 is provided with extruder 2, and described extruder 2 comprises hopper 4, barrel 5 and the first screw rod 6, is provided with the second screw rod 7 bottom described hopper 4, the bottom of hopper 4 is communicated with barrel 5 by feed pipe 8, and described first screw rod 6 is located in barrel 5; Described frame 1 one end is provided with the first motor 15, first motor 15 and is connected with the power shaft of reduction box 16, and the output shaft of reduction box 16 is connected with the first screw rod 6; Described second screw rod 7 is driven by the second motor 17, second motor 17 is fixed on reduction box 16 by fixed mount 18, the port of export of described barrel 5 is provided with head 9, the middle part of barrel 5 has steam vent 10, and the inwall of described barrel 5 is provided with the shearing screw thread 19 consistent with the transmission direction on the first screw rod 6; Described air filter 3 comprises aspiration pump 12, blast pipe 13 and settling tank 14, the air inlet of aspiration pump 12 is connected with bottom in inverted trumpet-shaped air intake duct 20, the exhaust outlet of aspiration pump is connected with blast pipe 13, the other end of blast pipe 13 is inserted in settling tank 14, described air intake duct 20 is provided with arm 21, and the other end of arm 21 is arranged on the top of head 9.
