Application and working principle of vertical drying mixer: Use the
rapid rotation of the screw to lift the raw materials from the
bottom of the barrel from the center to the top, and then throw
them down in an umbrella shape, and then return to the bottom, so
that the raw materials roll up and down in the barrel for drying
and mixing, and a large amount of raw materials can be uniformly
dried and mixed in a short time complete. The material flow has no
dead ends, no accumulation, no powder spills, and a large loading
factor. It is mainly suitable for the mixing and stirring of
various plastic raw materials, crushed materials, plastic sheets,
plastic pellets, shaped materials, crushed materials and color
masterbatches, new and old materials and The color masterbatch
mixing effect is better. It is one of the necessary equipment for
injection molding machine and extruder. The core patents of vertical drying mixer: A1: The hot air of the traditional dryer enters from the lower side
of the barrel. Because the material is static, the hot air is more
difficult to penetrate, which makes the inside of the dryer heat up
and down, and sometimes the material is overheated. Blocks, causing
blockage, making it more difficult for hot air to enter other
areas, so the originally expected drying effect cannot be achieved.
The design of this machine is a two-stage screw conveyor. The first
stage feeds the raw materials into the barrel, and the second stage
continuously lifts the raw materials to the upper part of the
barrel and throws them in an umbrella shape, while the hot air
blows out from the center of the lower part of the barrel. ,
Smoothly penetrate upwards from the gap of the moving raw
materials, the raw materials are fully heated under dynamic
conditions; A2: The dryer barrel is designed as a double-layer
barrel design, with special insulation materials in the middle,
which achieves the effect of heat preservation and energy saving;
the inner layer is made of stainless steel for the material contact
part; the middle sandwich is installed and special insulation
materials, so It can achieve the effect of safety and energy
saving; A3: Special high-frequency heater, fast heating, low power
consumption, and the comprehensive cost of drying per ton is 25-30
yuan/ton; A4: The special double-pipe moisture exhaust port can
effectively discharge moisture, collect dust, and never pollute the
working environment; A5: This model has the characteristics of more
work: because the materials are constantly tumbling up and down in
the barrel, the hot air is not lifted from the center for
transportation, so as to achieve the effect of mixing and drying.
If drying is not required, this series of machines The type can be
set as a separate mixing work mode; A6: Two-in-one drying and
mixing function. When drying is not required, just turn off the
"heating switch" and "fan switch", and this series of models can be
used for plastic mixing and homogenization purposes, one machine
for two purposes; |
