Automobile plastic product granulating system
Technical field
The utility model is related to a kind of automobile plastic product granulating system, belongs to machinery equipment field.
Background technology
Granulated in the material to plastic material, it is necessary to be first passed through batch mixing, the material use that will be melted into extruding machine
Mould extrudes strip, makes its hardening to facilitate pelletizing by water-cooled from extruding machine plastic strip out, the bar after water cooling
Expect unavoidable surface can adhesion moisture, be nowadays all material is directly blown using air blower so that the moisture drying of surface of material and
Further cooling.Or wind is guided to by bar top by a pipeline, and it is then aligned with bar and is blown, such a side
Upward fixed point blows the moisture often resulted on bar can not be blown away well, and drying effect is poor, it is possible to need multiple drums
Blower fan synergy, high energy consumption.
Even if air-cooled using air blower, cannot also ensure a small amount of water droplet of adhesion on bar.At present, air blower cooling
Pelleter pelletizing is just directly entered afterwards, and the water droplet of adhesion has little time drippage, it is impossible to ensure that strip-shaped materials can reach before pelletizing
Dry and require.
In addition by the material after pelleter pelletizing, directly it is pumped into mixing tank greatly using conveying, material is also again without drying
Operation, it is impossible to ensure the drying of material, and existing tank mixed greatly is also not provided with drying equipment, influences the matter of plastic products
Amount.
Finally, extruding machine has substantial amounts of exhaust emissions during work, and tail gas is by the tail on extruding machine body
Gas steam vent is discharged, and the exhaust temperature of discharge is higher, and at present, tail gas is to be directly pumped vent gas treatment by tail gas blower unit
Device is discharged after being processed, and its heat is not recycled, and causes the waste of a large amount of heat energy.
