Specific embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to specific embodiment
And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit scope of the present utility model.Additionally, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Fig. 1 show the insulation cover structure of traditional extruder barrel.
As shown in figure 1, traditional heat insulation shield constitutes heat-insulation layer simultaneously using the parcel alumina silicate of aluminium masking foil 1 heat-preservation cotton 2
It is fixed on stainless steel outer cover 3, because stainless steel outer cover 3 can conduct heat, is easily caused scald.In addition, in fixed heat-insulation layer, by
In too near (general spacing is in 20~30mm) that heat-insulation layer can not be close to cylinder or lean on, heat insulation effect is caused to reduce, heat stream
Mistake is more, and energy consumption is big.Meanwhile, alumina silicate heat-preservation cotton 2 (learn and claim alumina silicate fibre) is the refractory fibre with flint clay melting,
Long-term suction fibre dust, it is very big to harm, easily cause the various diseases of lung.
Fig. 2 show extruder barrel cross-sectional structure schematic diagram of the present utility model.
