Description

TECHNICAL FIELD

[0001] The present application relates to the transmission technology field of devolatilization mixers, in particular to a transmission box for a horizontal three-rotor devolatilization mixer. BACKGROUND

[0002] In the related industries of new polymer materials, rubber, polymer, fiber and engineering plastics, when processing and treating some high-viscosity materials, the equipment often encounters the following difficult problems:

[0003] 1. During the stirring process of ultra-high viscosity fluid, the cylinder wall and stirring shaft may be adhered, and it is difficult to uniformly mix or uniformly heat the ultra-high viscosity fluid and low viscosity fluid in a short time.

[0004] 2. During the production and manufacturing process of some materials, the high-viscosity fluid gradually changes from liquid phase to solid phase, the temperature changes with the reaction condition, and the viscosity span of the material changes greatly, so the common mixer is difficult to adapt.

[0005] Due to the poor self-cleaning of the ordinary mixer, the material accumulates, which further causes the poor consistency of product performance, and in severe cases, the material forms a "dead zone" in the cylinder, which further expands to cause the rotation shaft to be locked, so that the production cannot continue.

[0006] In order to overcome the defects that the ordinary mixer in the prior art is prone to cause material accumulation and rotation shaft locking due to poor self-cleaning, a horizontal double-rotor devolatilization mixer is developed, which well solves the problems of the ordinary mixer. However, for large-capacity devolatilization and high-shear occasions, the capacity of the horizontal double-rotor devolatilization mixer is slightly insufficient, and the shear capacity is also insufficient. The single-section cylinder of the horizontal three-rotor devolatilization mixer has three cavities, and the capacity is 1.5 times that of the single-section cylinder of the double-rotor devolatilization mixer. The double rotors are engaged with each other, and there is only one engagement zone. The three rotors are engaged with each other in pairs, and there are two engagement zones, so the shear capacity is twice that of the original. Based on this, a transmission box for a horizontal three-rotor devolatilization mixer is provided. SUMMARY
