Specific implementation mode
The embodiment further illustrated the present invention below in conjunction with the accompanying drawings with example：
The present invention provides a kind of improved double screw extruder powder bucket special, including barrel 1, feed screw 2, auxiliary feeding
Rotor 3, dust gathering arrester 4, pump 6 and disposal box 8；
Its design feature is that the auxiliary feeding rotor 3 is located at 2 top of feed screw, and the wall surface of barrel 1 is in ramp structure, auxiliary
Feeding rotor 3 is located at the adjacent on the inclined-plane of barrel 1 and at regular intervals with barrel inclined-plane；
The lower ending opening of the dust gathering arrester 4 covers on 1 top of barrel, and 4 upper end of dust gathering arrester is connect with first pipe 5；
The pump 6 is fixed on 5 end of first pipe；It is terminated on pump on second pipe 7；
The disposal box 8 is located at second pipe lower end.
The cross sectional shape of above-mentioned barrel include top face directly and with the inclined-plane facing lower end directly and connect, inclined-plane accounts for barrel height
One third, face directly and account for 2/3rds of barrel height.
The feed screw is single screw rod, and wall surface of the single screw rod apart from barrel 1 is at regular intervals.
The auxiliary feeding rotor has 4 fan blade rotors, and 4 fan blade rotors are equally distributed on centre bearing periphery, auxiliary
Feeding rotor is helped to be fixed by centre bearing, and fan blade rotor has larger area, and at regular intervals with the inclined-plane of barrel 1, this
Spacing（For those skilled in the art best spacing can be obtained by groping）The powder that inclined-plane from barrel 1 gets off is led to
The effect of fan blade rotor is crossed, powder accumulation and bridging action, while the further uniformity for improving powder are destroyed（This is the present invention
Key）, finally can squeeze out blanking by feed screw 2.
The dust gathering arrester 4 includes the tubular sections and taper dust section of integrally connected, and the taper dust section is located at material
The surface of cylinder, connect with the upper port of the tubular sections of taper dust section integrally connected with first pipe 5, mouth under taper dust section
It is slightly less than the opening of barrel.
The disposal box 8 is connect with 7 lower end of second pipe, is equipped at 2/3rds height positioned at disposal box surface
Glass window is equipped with rotation gate valve convenient for dust situation in observation case on the right side of disposal box, can be by rotating gate valve effectively
Dust in wash-up tray.
Double screw extruder powder bucket special, including barrel 1, feeding spiral shell are improved specifically, being disclosed in this example
Bar 2, auxiliary feeding rotor 3, dust gathering arrester 4, first pipe 5, pump 6, second pipe 7, disposal box 8.1 one third shape of the barrel
Shape is inclined-plane, and dust gathering arrester is connected in the surface of barrel 1 and with pipeline 1, and mouth is slightly less than barrel opening, institute under dust gathering arrester conical section
Pump 6 is stated in 5 end of first pipe, first pipe 5 is connected with second pipe 7, and disposal box 8 is located at the end of second pipe 7
Place.
It is for the ease of powder blanking under ramp effect that 1 one third shape of barrel, which is inclined-plane, in said program, is anti-
Only powder assists feeding rotor 3 to be acted on by fan blade in inclined stacking, the behaviors such as bridge formation, destroys powder accumulation and bridging action,
The further uniformity for improving material simultaneously squeezes out blanking, the dust gathering arrester 4 and first pipe finally by feed screw 2
Road 1 is connected, and mouth is open less than barrel 1 under conical section, and convenient for observation powder in barrel situation, the pump 6 is in first pipe 5
End, first pipe 5 are connected with second pipe 7, and second pipe bore is more than first pipe bore, convenient between pipeline
Dismounting and cleaning, while overhauling and maintaining for time lower pump for a long time is also allowed for, the disposal box 8 is located at the end of second pipe 7
At end, there is glass window on disposal box surface, it is observed that dust situation in case, there is rotation gate valve on disposal box right side, passes through rotation
Revolving door valve action, can immediately dust in wash-up tray.
Operation principle：Powder passes through fan blade action breaks down bridging of powder by 1 inclined-plane blanking of barrel, auxiliary feeding rotor 3
Material uniformity is improved with sedimentation, blanking is being squeezed out by feed screw 2, when needing dedusting, is opening pump 6, is being made in pump
Under, powder being flown upward by first pipe 5 and second pipe 7 in air, is fallen into disposal box 8, disposal box glass window is seen
Examine can babinet dust to a certain extent when open on the right side of rotate gate valve, dust in instant wash-up tray.
