Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane production, in particular to a high-speed dispersing kettle for polyurethane. Background Art

[0002] Polyurethane, whose full name is polyurethane, is a polymer compound. Polyurethane is divided into two categories: polyester type and polyether type. They can be made into polyurethane plastics (mainly foam plastics), polyurethane fibers (called spandex in China), polyurethane rubbers and elastomers. Soft polyurethane is mainly a thermoplastic linear structure. It has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has smaller compression deformation. It has good heat insulation, sound insulation, shock resistance and anti-toxic properties. Therefore, it is used as packaging, sound insulation and filtration materials. Hard polyurethane plastic is light in weight, has excellent sound insulation and heat insulation properties, is resistant to chemicals, has good electrical properties, is easy to process and has low water absorption.

The spiral motor is fixed on the dispersion working tank. The dispersion working tank is a tank structure. The output shaft of the spiral motor is connected to the main stirring shaft through a coupling. Three auxiliary stirring shafts are evenly spaced on the same circumferential surface with the main stirring shaft as the center. The main stirring shaft drives the auxiliary stirring shaft to rotate. The lower end of the main stirring shaft is connected to a U-shaped stirring frame, and the main stirring shaft is provided with a plurality of stirring blade mechanisms spaced up and down. The above-mentioned multiple stirring structures are set, wherein the main stirring shaft drives the U-shaped stirring frame and the stirring blade to rotate, so that the raw materials are stirred horizontally, the auxiliary stirring shaft drives the blade to rotate, and its spiral blade also rotates, so that the raw materials are stirred vertically. Multiple stirring structures are used for stirring, and the stirring effect is good.
