Abstract
The open a kind of quantitatively screw rod conveyor of the utility model, comprise one-level hopper, secondary hopper, screw conveying device and arch breaking apparatus, described one-level feed hopper bottom is equipped with arch breaking apparatus, the bottom of described one-level hopper is also provided with inclined-plane expanding channels second hopper, the second hopper connecting screw rod feedway.The material stock height of one-level hopper, by the design of secondary hopper, while horizontal arch breaking apparatus is incorporated into screw rod conveyor, is eliminated the impact of the degree of packing, thus is greatly provided the screw rod transmission stability of screw rod conveyor by the utility model.
Description
Technical field
the utility model relates to a kind of screw conveying device, more specifically, relates to a kind of quantitatively screw rod conveyor.
Background technology
The extrusion molding such as Rigid PVC Pipe, section bar product directly uses powderous primary material to produce usually, usually first material being thrown into extruder hopper, then quantitatively delivering to extruder dog-house with screw rod conveyor and producing when producing.The stability fed intake directly has influence on the stability that extruder is produced.
The screw rod transmission principle of quantitative screw rod conveyor belongs to volume screw rod transmission, and the speed of screw rod transmission and the loose thickness degree of association of material are comparatively large, therefore ensure the loose thickness of material basically identical guarantee screw rod transmission velocity-stabilization.Because PVC grog material is powder-material, pressure suffered by material is very large on the impact of its loose thickness, the hopper now adopted is common hopper, the shatter value of hopper stage material is relevant with hopper material stock height, material stock is higher, and the thrust of upper layer of material to subsurface material is larger, and the loose thickness of material is larger, thus cause the speed hopper material stock height of screw rod transmission to affect, have impact on the stability that extruder is produced further.
Prior art: as shown in Figure 1, due to the direct connecting screw rod feedway of hopper, so arch breaking apparatus can only adopt vertical placement, makes edge can not obtain good stirring.
Utility model content
The purpose of this utility model is, provides the screw rod transmission stability improving quantitative screw rod conveyor.
According to above object, first the utility model provides a kind of quantitatively screw rod conveyor, comprise one-level hopper, secondary hopper, screw conveying device and arch breaking apparatus, described one-level feed hopper bottom is equipped with arch breaking apparatus, the bottom of described one-level hopper is also provided with inclined-plane expanding channels second hopper, the second hopper connecting screw rod feedway.
Described arch breaking apparatus is a horizontally disposed puddle mixer.
The mixing device of described puddle mixer is added root vertical rod by a horizon bar and is formed.
The mixing device of described puddle mixer is corrugated mixing device.
The mixing device of described puddle mixer is added root horizon bar by a vertical rod and is formed.
Described arch breaking apparatus is flood dragon type mixing device.
The capacity of described one-level hopper is 2 ~ 5 times of secondary hopper.
Described screw conveying device is screw rod screw conveying device.
The utility model has the advantage of:
1. the utility model is by increasing secondary hopper, makes the material stock height of one-level hopper on secondary material all without impact, the fluctuation of minimizing rate of feeding, thus improves the stability of screw rod transmission.
2. the utility model is by increasing secondary hopper, makes one-level hopper arch breaking apparatus change into horizontal direction from original vertical direction, better can carry out broken arch to base material like this, thus improves the stability of screw rod transmission.
3., due to the existence of secondary hopper, make to adopt multiple different broken arch structure to become possibility.
4., after using quantitative screw rod conveyor of the present utility model, the stability of screw rod transmission improves greatly, thus the material stock of one-level hopper, can not impact quantitative screw rod transmission again.
