The recycling of waste or used plastics and resource development, it is derived from the heightened awareness to environment and resource, reducing waste or used plastics to the pollution of environment and the minimizing wasting of resources is a kind of life style, it is the major issue benefited the nation and the people, it is estimated that, often utilize one ton of waste or used plastics, the energy more than 85% can be saved compared with processing raw material, save processing charges 70-80%, be equivalent to save 20 tons of oil.
Waste plastic regeneration process; need elder generation waste or used plastics through over cleaning; it is dried then, plasticizing melted with the screw extruder of plastic reclaimed extrusion device again; it is extruded into strip; again through cooling device cooling; finally using pelleter to be cut into particle, these particles entered the technique deep processings such as blowing, injection, calendering again and became various plastic products.
Traditional single screw rod plastic extrusion device design structure is complicated, volume is big, production cost is higher, and bad to the processing effect of waste or used plastics, production efficiency is low.Meanwhile, waste or used plastics usually contains some metal impurities, thus affect the quality of plastics.Additionally, the heater of barrel needs constantly heating to maintain the temperature of barrel, cause the waste of energy.
To this end, designer of the present utility model is because drawbacks described above, by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of constant temperature plastic extruder, to overcome drawbacks described above.
Content of the invention
The purpose of this utility model is to provide a kind of constant temperature plastic extruder, and it is reasonable in design, simple in construction, using twin-screw design, working (machining) efficiency is higher, eliminates the impurity in product, ensure that the quality of product, and can also effectively ensure the heating-up temperature of whole barrel, make heat effectively utilize.
For solving the problems referred to above, the utility model discloses a kind of constant temperature plastic extruder, including barrel and be arranged on screw rod within barrel, described screw rod is two, is connected with actuating unit respectively；It is provided with on described barrel and plastics are sent into the hopper within barrel；It is provided with the heater entering heating to barrel on described barrel；
Described heater is multiple, is disposed in parallel on barrel；On described barrel, each heater corresponding is provided with temperature inductor；Described heater is heating wire or electric heating piece；
Being provided with heat-insulation layer on described barrel, described heat-insulation layer includes heat-preservation cotton.
Wherein, described screw rod includes the body of rod, and the described body of rod is provided with screw thread, and described screw thread is double thread, is provided with cavity in the described body of rod, is provided with straight-bar and the heater strip being wrapped on straight-bar in described cavity.
Wherein, described material tube inner wall is provided with zinc coat.
Wherein, the surface configuration of described screw rod has Kazakhstan C-276 alloy welding deposit anticorrosive coat.
Wherein, the bottom of described barrel is provided with skimming door to be opened/closed, and described skimming door is internally provided with permanent magnet.
Wherein, described hopper is provided with vibrating device.
By said structure, constant temperature plastic extruder of the present utility model has the effect that
1st, reasonable in design, simple in construction, use twin-screw design, working (machining) efficiency is higher；
2nd, the impurity in product is eliminated, it is ensured that the quality of product；
3rd, can effectively ensure the heating-up temperature of whole barrel, make heat effectively utilize.
Detailed content of the present utility model can be obtained by explanation described later and institute's accompanying drawing.
