Abstract
The utility model discloses a kind of exhaust apparatus for extruder, including the discharge duct being connected with extruder barrel, the side wall of discharge duct is also associated with trachea, and the trachea is provided with suction pump, the waste gas produced in extruder barrel can be extracted out and is emitted into outside extruder by suction pump work.The first screw rod and the second screw rod being arranged side by side is provided with discharge duct, the first driven gear and the second driven gear are respectively equipped with the top of first screw rod and the second screw rod, motor is additionally provided with the top of discharge duct, driving gear is arranged with the output shaft of motor, driving gear is engaged with the first driven gear and the second driven gear respectively, and electrical power can drive the first screw rod and the second screw rod to rotate.When extruder runs, waste gas is extracted discharge via discharge duct, and in the process by electrical power, motor drives the first screw rod and the rotation of the second screw rod, and the material pressure that will rise with waste gas in extruder barrel prevents which from discharging with waste gas, causes to waste.
Description
Technical field
This utility model is related to extruder field, more particularly to a kind of exhaust apparatus for extruder.
Background technology
When extruder runs, large quantity of exhaust gas is produced in extruder barrel, in order to by the waste gas discharge in extruder barrel
Go out, it will usually install a discharge duct on extruder barrel additional, by aspirating pumping waste gas and emitting.
Again by aspirating during pumping waste gas, have a small amount of material and discharge duct is sucked up with waste gas and is discharged, cause thing
Material is wasted.
Utility model content
The purpose of this utility model is that, in order to solve shortcoming present in prior art, and the one kind for proposing is used for extruder
Exhaust apparatus.
To achieve these goals, this utility model employs following technical scheme：
A kind of exhaust apparatus for extruder, including the discharge duct being connected with extruder barrel, the discharge duct
Side wall be also associated with trachea, the trachea is provided with suction pump；The first screw rod being arranged side by side is provided with the discharge duct
With the second screw rod, the first driven gear and the second driven gear, institute at the top of first screw rod and the second screw rod, are respectively equipped with
State, on the output shaft of motor, be arranged with driving gear, the driving gear is respectively with
One driven gear and the engagement of the second driven gear, electrical power drive the first screw rod and the second screw rod to rotate.
Preferably, the motor is provided with sealing ring with discharge duct contact position.
Compared with prior art, the beneficial effects of the utility model are：When extruder runs, produce in extruder barrel
Large quantity of exhaust gas, now needs to open suction pump by waste gas extraction discharge, at the same time has a small amount of material and be sucked up aerofluxuss with waste gas
Pipeline is simultaneously discharged, and causes material waste；In the process by electrical power, motor drives the first screw rod and the rotation of the second screw rod,
The material pressure that will rise with waste gas in extruder barrel, prevents which from discharging with waste gas, causes to waste.
Description of the drawings
Fig. 1 be the utility model proposes a kind of exhaust apparatus for extruder structural representation；
Fig. 2 is A-A in Fig. 1 to sectional view；
Side views of the Fig. 3 for Fig. 1.
In figure：1st, extruder barrel, 2, discharge duct, the 3, first screw rod, 4, motor, 5, driving gear, 6, first is driven
Gear, 7, trachea, 8, suction pump, the 9, second driven gear, the 10, second screw rod.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.
Reference picture 1-3, a kind of exhaust apparatus for extruder, including the discharge duct 2 being connected with extruder barrel 1,
The side wall of the discharge duct 2 is also associated with trachea 7, and the trachea 7 is provided with suction pump 8, and suction pump 8 works, and will can extrude
The waste gas produced in machine barrel 1 is extracted out and is emitted into outside extruder.
It is provided with the first screw rod 3 and the second screw rod 10 being arranged side by side in the discharge duct 2, first screw rod 3 and the
The top of two screw rods 10 is respectively equipped with the first driven gear 6 and the second driven gear 9, and the top of the discharge duct 2 is additionally provided with
Motor 4, is arranged with driving gear 5 on the output shaft of motor 4, the driving gear 5 respectively with the first driven gear 6 and second from
Moving gear 9 is engaged, and motor 4 is powered and the first screw rod 3 and the second screw rod 10 can be driven to rotate.When extruder runs, extruder
Large quantity of exhaust gas is produced in barrel 1, is now needed to open suction pump 8 by waste gas extraction discharge, a small amount of material is at the same time had with useless
Gas is sucked up discharge duct 2 and discharges, and causes material waste；In the process motor 4 is powered, motor 4 drives the first screw rod 3
Rotate with the second screw rod 10, the material pressure that will rise with waste gas in extruder barrel 1 prevents which from discharging with waste gas, causes wave
Take.The motor 4 is provided with sealing ring with 2 contact position of discharge duct.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
