Bar extruder.
In order to realize above-mentioned purpose of utility model, the utility model the following technical schemes are provided:
A kind of feed back is granulated dedicated vented single -screw extruder in the utility model, including head, machine barrel, screw rod plus
Hopper, natural gas vent, heat block, gearbox, power device and shaft coupling, which is characterized in that be additionally provided on the machine barrel true
Empty room adds vacuum pump outside the vacuum chamber, is in melt under condition of negative pressure by vacuumizing mode, by steam and material
Material decomposes the gas generated and detaches, and vacuum filtration hole is additionally provided on the machine barrel, the vacuum filtration hole is located at exhaust section, used
Screw rod is the exhaust-type single-screw being transformed with Vacuum filtration device cooperation, and the screw rod includes feeding section, the first compression section, first
Metering end, exhaust end, the second compression section and the second metering section, second metering section is located at the left side of the second compression section, described
Second compression section is located on the left of exhaust section, and the feeding section is located at the right end of screw rod, the exhaust section added, the second compression
Section, the second metering section cooperation vacuum pump use, and improve melt and are exposed to the time under condition of negative pressure, increase exhaust effect.
The nature gas vent is located at the first metering section.
The power device is motor.
The draw ratio of the screw rod is 30:1~50:1.
The shaft coupling of the left side connecting screw extruder of the gearbox, the right side connecting power device of the gearbox
Shaft coupling.
Advantages and beneficial effects of the utility model lie in that provide it is a kind of can effectively detach steam and material and decompose generate
Gas improves production efficiency, saves energy consumption, reduce equipment cost without carrying out drying and processing in advance before feed back is granulated
Single screw extrusion machine.It is screw rod relevant design that existing exhaust-type single-screw, which squeezes out related patents, but using effect and is paid no attention to
Think.Though the utility model is related to screw design, predominantly cooperate vacuum filtration system, improves melt and stopped under condition of negative pressure
Time.It installs vacuum pump additional, vacuum hole is made to be formed about negative pressure, original compressed and package gas and small after gasification in melt
Molecular substance foams in melt, and the bubbles burst under negative pressure and screw acting is taken away by vacuum pump.The setting of second compression section
Melt is effectively increased in the residence time of exhaust section, is sufficiently exposed under condition of negative pressure, enhancing vacuum filtration effect.
