Horizontal double-shaft mixing devolatilization machine

Abstract

The horizontal double-shaft mixing devolatilization machine comprises a rack, the rack is connected with a barrel assembly through a barrel support assembly above the rack, a rotor shaft assembly is arranged in the barrel assembly, a dynamic sealing assembly hydraulic station is arranged on one side of the outer portion of the barrel assembly, and an exhaust chamber assembly is arranged above the barrel assembly; a feeding end dynamic sealing assembly and a discharging end dynamic sealing assembly are installed at the two ends of the rotor shaft assembly respectively and connected with the rack through dynamic sealing supports. A stirring claw on the rotor shaft assembly is good in self-cleaning capacity, the included angle between the stirring claw and the axis is changed, the forward pushing speed of materials in the barrel is controlled by changing the rotating speed of a rotor shaft, the mixing effect of the materials is improved, and the sealing reliability is improved through the special dynamic sealing design of the feeding end and the discharging end and a dynamic sealing hydraulic station. And a heating medium or a refrigerant is introduced into the cylinder jacket, the rotor shaft and the turntable, so that the heat exchange area is enlarged, and heat transfer or cooling is more uniform and quicker.

Description

technical field [0001] The invention relates to a horizontal double-shaft mixer, in particular to a horizontal double-shaft mixing and devolatilizing machine. Background technique [0002] In related industries such as new polymer materials, rubber, polymers, fibers, engineering plastics, etc., the equipment often encounters some difficult problems when processing and processing some high-viscosity materials, such as: [0003] 1. During the stirring process of the ultra-high viscosity fluid, there will be a phenomenon that the material adheres to the cylinder wall and the stirring shaft; it is difficult to mix the ultra-high viscosity fluid and the low viscosity fluid phase with each other uniformly or evenly heat transfer in a short time; [0004] 2. The production process conditions are harsh, and some high-performance polymers must be processed under strong acid, strong alkali, high temperature and high vacuum conditions to produce ideal materials; [0005] 3. The produc...
