Wherein, aforesaid a kind of blanking device, described surge tank is made up of the hollow tank body of back taper, jar mouth and the outlet(discharge) flange of upper surface sealing, the jar mouth is a cylindrical pipe, is positioned at tank body upper surface centre, and its lower end and tank body upper surface fuse, there is an adpting flange jar mouth upper end, the flange butt joint of this adpting flange and tremie pipe lower end, outlet(discharge) flange is fixed on the tank body below, is used for the connecting screw rod extruder.
Aforesaid a kind of blanking device, the hollow tank body of described back taper are chamfered edge taper or the hollow tank body of turbination
Aforesaid a kind of blanking device is connected with a telescoping tube between described jar mouth and the tremie pipe.
Aforesaid a kind of blanking device is equipped with a valve on the described tremie pipe.
Aforesaid a kind of blanking device, all sides of described surge tank are equipped with a form.
Blanking device of the present utility model, not welding is also seamless between the tank interior face of surge tank and the face, very smooth, all pads make things convenient for particle to pass through smoothly entirely outside, jar interior sealing effectiveness is very good in addition, be enough to guarantee the material quality, and whole profile looks very attractive in appearance.Just the raw material of driving drops into the big material bin on upper strata, behind positions such as intermediate conduit, valve, telescoping tube, enter surge tank smoothly, the timely controlling opening of valve of basic condition of the form reflection by buffering, after surge tank is filled, the blanking valve is all opened, and by the rotation of screw extruder, the particle in the surge tank enters in the extruder very uniformly.
The surge tank that is applicable to a kind of blanking device of the present utility model also comprises: the beveled structure device is done in A, screw extruder porch; The device of B, use throttling porous plate; C, working pressure control valve device; D uses the N2 protective device; E, use metering device; F, use spiral tube device etc.The purpose that cushions is realized in the path that the utility model passes through by the sectional area that changes raw material and pass through and raw material.
The beneficial effects of the utility model are: rational in infrastructure, reliable, and good buffer effect, the screw extruder inlet pressure is stable; All stainless steel can not corrode good sealing effect, high insulating effect.
Description of drawings
Fig. 1 is the structural representation of a kind of blanking device of the present utility model.
Among the figure: the 1st, adpting flange 2 is that jar mouth 3 is that tank body 4 is that form 5 is that outlet(discharge) flange 6 is that spinning feed bin 7 is that valve 8 is that tremie pipe 9 is that telescoping tube 10 is screw extruders.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The present invention also provides a kind of blanking device, comprises spinning feed bin 6 and is positioned at the RC tremie pipe 8 in spinning feed bin bottom, and it is characterized in that: described tremie pipe 8 is connected 10 through surge tank and screw extruder.
Wherein, aforesaid a kind of blanking device, described surge tank is made up of the hollow tank body 3 of back taper, jar mouth 2 and the outlet(discharge) flange 5 of upper surface sealing, jar mouth 2 is a cylindrical pipe, is positioned at tank body 3 upper surface centres, and its lower end and tank body 3 upper surfaces fuse, there is an adpting flange 1 jar mouth 2 upper ends, the flange butt joint of this adpting flange 1 and tremie pipe 8 lower ends, outlet(discharge) flange 5 is fixed on tank body 3 belows, is used for connecting screw rod extruder 10.
