The charge cask of the automatic stirring device of existing double screw extruder includes hopper and agitator, and described hopper is by outward
Wall is constituted, and this outer wall forms accommodation space and is used for filling raw material.The right side of described hopper connects charging aperture, and the bottom of hopper connects
Preheating device, after the heating of described preheating device, blows in hopper by aerator by hot blast, preheats raw material.But this
The charge cask of kind of structure easily makes heat be delivered to outside from outer wall, causes amount of heat to run off, programming rate is slow, energy consumption
Too high, and owing to outer wall distributes heat, cause the working environment backing hot near drying machine.
The cooling system great majority of existing double screw extruder use water circulating cooling, and circulation is for production equipment
Implement water cooling and configure, using water as cooling medium, and a kind of cooling water system recycled.Current type of cooling meeting
Use air-cooled and water-cooled two kinds, owing to the speed of wind cooling temperature lowering is slow, so more extruder uses this mode of water-cooled,
Being i.e. water inlet by water pipe one end, the other end is outlet, is circulated by water and reaches the purpose of cooling, and this mode reaches not
To the effect of control temperature very well, and the easy fouling of water pipe, cooling effect can be caused the best, product lumps, and quality does not reaches
Requirement.
It is then desired to develop a kind of Novel double-screw extruder both there is preferable heats, have again preferably
Cooling effect.
