[Abstract] Mixer is a highly efficient mixing equipment for chemical, pharmaceutical, oil and building materials. Can be used in powder and the powder and liquid, liquid and liquid mixture. Therefore, the mixer is widely used in contemporary. DL-4 single-screw conical mixer for mixing than the traditional roller to improve the effectiveness of 10 times, with mixed speed, mixing high precision, low power consumption, loading coefficient, smooth and reliable operation and good operating conditions, cleaning and maintenance convenience and long life. It is particularly suitable proportion of the poor, mixed particle sizes of materials. The feature is that it is only a mixing screw, the mixing screw is located at the bottom of the shaft within the bearing housing from the extended and they can bring it to the next rotation of the output shaft gear; and can bring the mixing spiral arm of the revolution of the transfer; bearing installed in the chassis in the bottom of the mixing screw to allow it as a revolution where the shaft bearing in the outer support points, so as to solve the existing single-screw conical mixer too big and complex structure of energy consumption and material use are risk of contamination by oil and other issues, DL-4 single-screw conical mixer's main components are gear, cylindrical gear drive, bevel gear, bearing, stirring spiral. The design mainly includes design of transmission scheme, the relevant calculation of gear drive, motor and reducer selection, and use the related graphics software design and processing of parts.
