The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, double screw extruder of the present invention provides the motor 1 of main frame power to be direct current generator, and power 250kw, rotating speed 1500r/min, motor 1 link to each other with high-power transmission case 2, and high-power transmission case 2 output shafts and cylindrical shell 3 interior parallel dual-screws are connected.
The high-power transmission case 2 that the present invention adopts is the transmission case of German Henschel Antriebstechnik GmbH, power of motor is 250kw, moment of torsion 1910Nm, moment of torsion grade 8.7, production capacity can reach 700-1300kg/h, and common homemade transmission case is under same screw speed, centre-to-centre spacing condition, power of motor is 132kw, moment of torsion 990Nm, moment of torsion class 4 .6, production capacity only is 350-600kg/h.
Through high-power transmission case 2 decelerations, distribute torque, output speed is 100-1000r/min.High-power transmission case 2 is by the driving of two shaft couplings realization to screw rod, and screw rod rotates in cylindrical shell 1, realizes conveying, fusion, shearing, mixing and exhaust etc. to material, and to material compression build-up pressure, the realization material is extruded from die head at last.
Motor 1 output shaft links to each other with high-power transmission case 2 by safety coupling 4, can guarantee that high speed, high-precision drive unit exempt from overload and destroy, and can the separation moment of torsion be set according to the real work needs.
On the cylindrical shell 3 in cylindrical shell motor 6 output shafts of the feeding machine 5 of defeated material be connected with transmission case 7, transmission case 7 and feed box 8 interior feed screw 9, puddlers 10 link to each other, the discharging opening 11 of feed box is connected with cylindrical shell 3.
Be provided with heating system 12 and temperature detection, display unit outside the cylindrical shell 3.Before the driving, 12 pairs of cylindrical shells of heating system 3 and fervent head heat, and reach the technique initialization temperature, and unit by the effect of temperature control instrument, is realized the control to design temperature in operation process.
Main frame heating general power is 80.5kw.
Cylindrical shell 3 is divided into 11 sections, and each section heating power is as follows:
| Bringing-up section | ?1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | Head |
