Abstract
The utility model relates to a feeding device for powdery materials, in particular to a feeding device for a double screw extruder, and mainly solves the problem of fewer discharged materials and low efficiency in the conventional double screw extruder. The feeding device for the double screw extruder comprises a double screw extruder barrel and a feed hopper positioned at the end of the double screw extruder barrel; the feeding device for the double screw extruder is characterized in that a feed opening is formed on the side surface of the double screw extruder barrel, and a side feed hopper is arranged in the position corresponding to the feed opening; the feed opening is positioned at the second section or the third section of the double screw extruder barrel; and at most two side feed hoppers are arranged on the double screw extruder barrel. The output capacity of materials is increased through the additionally arranged side feed hoppers, and the working efficiency is further improved.
Description
Technical field
The utility model relates to a kind of granular material drawing-in device, specifically a kind of double screw extruder drawing-in device.
Background technology
At present in the production process of fire retardant, material is generally powdery, especially chlorine fire retardant material is comparatively fluffy, feeding hopper of the general employing of present employed equipment, material is delivered in the twin-screw cylindrical shell, transported material by the rotation of screw rod, but because material is fluffy, the material that enters in unit interval in the twin-screw cylindrical shell is less relatively, causes the few inefficient problem of discharging.
The utility model content
The purpose of this utility model is to provide a kind of double screw extruder drawing-in device, solves the few inefficient problem of double screw extruder discharging.
The technical scheme that its technical problem that solves the utility model adopts is: the double screw extruder drawing-in device, comprise twin-screw cylindrical shell and the feeding hopper that is positioned at twin-screw cylindrical shell end, it is characterized in that, the side of described twin-screw cylindrical shell is provided with charging aperture, is provided with the side feeding hopper with the corresponding position of charging aperture; Described charging aperture is positioned at second joint or the 3rd joint place of twin-screw cylindrical shell; Can be provided with two side feeding hoppers on the described twin-screw cylindrical shell at most.
The beneficial effects of the utility model are: increase the load of material by setting up the side feeding hopper, increase work efficiency.
Description of drawings
Fig. 1 is a front view of the present utility model,
Fig. 2 is a right view of the present utility model.
Among the figure: 1 twin-screw cylindrical shell, 2 feeding hoppers, 3 charging apertures, 4 side feeding hoppers.
The specific embodiment
As shown in Figure 1, the double screw extruder drawing-in device comprises twin-screw cylindrical shell 1 and the feeding hopper 2 that is positioned at twin-screw cylindrical shell 1 end, and the side of described twin-screw cylindrical shell 1 is provided with charging aperture 3, is provided with side feeding hopper 4 with charging aperture 3 corresponding positions; Described charging aperture 3 is positioned at second joint or the 3rd joint place of twin-screw cylindrical shell 1; Can be provided with two side feeding hoppers 4 on the described twin-screw cylindrical shell 1 at most.
Operation principle: during feeding, because material is more fluffy, so the material in the unit volume is less, causes the material that enters in the twin-screw cylindrical shell 1 less, but material changes under the heating in twin-screw cylindrical shell 1, volume-diminished remaining space occurs in the twin-screw cylindrical shell 1, and side feeding hopper 4 just in time is positioned at second joint or the 3rd joint place of twin-screw cylindrical shell 1, this moment is by the feeding of side feeding hopper 4, can increase the material number in the unit volume, thereby increase the load of material, increase work efficiency.
Claims (3)
1. the double screw extruder drawing-in device comprises twin-screw cylindrical shell and the feeding hopper that is positioned at twin-screw cylindrical shell end, it is characterized in that the side of described twin-screw cylindrical shell is provided with charging aperture, is provided with the side feeding hopper with the corresponding position of charging aperture.
2. double screw extruder drawing-in device according to claim 1 is characterized in that, described charging aperture is positioned at second joint or the 3rd joint place of twin-screw cylindrical shell.
