Description
Technical field
The utility model relates to Screw extruder technology fields more particularly to a kind of powder for extruder to mix dress
It sets.
Background technique
Currently, most widely used is screw extruder in the processing equipment of high molecular material.Screw extruder is to rely on
Screw rod rotation generate pressure and shearing force, can allow material sufficiently carry out plasticizing and uniformly mixing, by mouth mold at
Type.But in actual production process, powder squeezes out the product of (powder and powder mixing squeeze out, and powder and pellet mixing squeeze out)
Existing defects such as mix uneven, discharging shakiness and product layering etc..Meanwhile can exist during the actual processing of powder
Dust problem.
Utility model content
Technical problem to be solved by the utility model is: in order to solve the skill that the mixing of extruder powder is uneven in the prior art
Art problem, the utility model provide a kind of mixing apparatus of powdery row material for extruder.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of powder for extruder mixes dress
It sets, including mixing barrel, baffle and stirrer paddle, the upper end of the mixing barrel is provided with multiple feed inlets, mixes barrel
Lower section is connected with the feed inlet of extruder, and the baffle is inclined inside mixing barrel, and stirrer paddle setting is mixing
Bottom in barrel, the external transmission device of stirrer paddle, baffle are located above stirrer paddle, and overlooking baffle from top to bottom can
Block stirrer paddle completely, one end of baffle connect with the inner wall of mixing barrel, and the other end of baffle is free end, and the one of baffle
End is higher than the other end of baffle.Powder is passed through different chargings before extruder operation by the utility model mixing apparatus of powdery row material
Mouth enters mixing device and mixes, and baffle is obliquely installed, and can contribute to the downslide of powder and tentatively mixes, and can stop to stir
It mixes the dust that blade mixes powder to raise up, powder further progress is mixed.
Discharge port is arranged in the lower section of the mixing barrel, and the feed inlet of extruder and the discharge port of mixing barrel pass through feeding
Device is connected, and the other end of the discharge port and baffle that mix barrel is oppositely arranged.It is passed directly by forced-feeding device crowded
Out in machine, dust pollution is reduced.The other end of the discharge port and baffle that mix barrel is oppositely arranged, and is able to extend powder mixing road
Diameter is sufficiently mixed.
Further, it is also provided with exhaust outlet on the side wall of the mixing barrel, exhaust outlet is higher than one end of baffle.
Further, it is additionally provided with control device on the mixing barrel, control device can control the revolving speed of transmission device
And baffle one end and mixture inner wall between angle.
Further, the discharge port of the extruder is also connected with cooling device, traction device and granulation in turn from front to back
Device.
The utility model has the beneficial effects that the mixing apparatus of powdery row material for extruder of the utility model, in extruder
Before operation, powder is entered into mixing device by different feed inlets and is mixed, baffle is obliquely installed, can contribute under powder
Sliding and preliminary mixing, and the dust that stirrer paddle can be stopped to mix powder raises up, and mixes, makes to powder further progress
It is more uniform to obtain powder mixing, improves the quality of production.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is structural schematic diagram of the utility model for the mixing apparatus of powdery row material of extruder.
In figure: 1, mix barrel, 2, baffle, 3, stirrer paddle, 4, extruder, 5, transmission device, 6, control device, 7, cold
But device, 8, traction device, 9, prilling granulator, 10, drawing-in device, 11, exhaust outlet.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Figure 1, be the utility model optimum embodiment, a kind of mixing apparatus of powdery row material for extruder, including it is mixed
Barrel 1, baffle 2 and stirrer paddle 3 are closed, the upper end of mixing barrel 1 is provided with multiple feed inlets, mixes the lower section of barrel 1 and squeezes
The feed inlet of machine 4 is connected out, and baffle 2 is inclined inside mixing barrel 1, and stirrer paddle 3 is arranged in mixing barrel 1
Bottom, the external transmission device 5 of stirrer paddle 3, baffle 2 is located at 3 top of stirrer paddle, and overlooking baffle 2 from top to bottom can be complete
Stirrer paddle 3 is blocked entirely, and one end of baffle 2 is connected with the inner wall of mixing barrel 1, and the other end of baffle 2 is free end, baffle 2
One end be higher than baffle 2 the other end.Discharge port, the feed inlet and mixing barrel 1 of extruder 4 is arranged in the lower section for mixing barrel 1
Discharge port be connected by drawing-in device 10, the other end of the discharge port and baffle 2 that mix barrel 1 is oppositely arranged.Mixture
Exhaust outlet 11 is also provided on the side wall of cylinder 1, exhaust outlet 11 is higher than one end of baffle 2.Control dress is additionally provided on mixing barrel 1
6 are set, control device 6 can control the angle between the revolving speed of transmission device 5 and one end of baffle 2 and the inner wall for mixing barrel 1
Degree.The discharge port of extruder 4 is also connected with cooling device 7, traction device 8 and prilling granulator 9 in turn from front to back.
Assuming that there are two feed inlet (be also possible to three or four or more), powder for the upper end setting of mixing barrel 1
