High-viscosity liquid phase granulation equipment

Abstract

The invention provides high-viscosity liquid phase granulation equipment, which comprises a precipitation tank, a dispersion cylinder, a liquid dropping disc and a liquid dropping pipe, the liquid dropping disc is provided with a disc surface and a rotating shaft, the rotating shaft is located at the central position of the disc surface and is perpendicular to the disc surface, the disc surface can freely rotate around the central axis of the rotating shaft, the rotating shaft is obliquely arranged, and the liquid dropping pipe drips a polymerization liquid to the disc surface. And the polymerization liquid is scattered into the eluate through the disc surface. According to the dropping tray, under the eccentric action of the high-viscosity reaction liquid in the dropping pipe, the high-viscosity reaction liquid rotates along with the dropping tray, on one hand, the dropping tray can play a role in dispersing the high-viscosity reaction liquid, and continuous or large-particle solids are prevented from being accumulated and separated out of the reaction liquid; and on the other hand, the viscous effect of the high-viscosity reaction liquid and the liquid dropping tray is effectively overcome under the dual effects of the centrifugal effect and the gravity of the liquid dropping tray, similar to that of water drops, the high-viscosity reaction liquid uniformly and quickly enters the precipitation liquid, so that solids with uniform particle sizes are formed, and meanwhile, the precipitation groove adopts a large opening type design, so that blockage can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of resin processing, and relates to a resin mechanical granulation equipment, in particular to a high-viscosity liquid phase granulation equipment. Background technique [0002] High heat-resistant resins, such as polysulfone resins, polyphenylene sulfide resins, polyether ether ketone resins, polyarylether nitrile resins, etc., have excellent heat resistance and good mechanical properties, dielectric properties, and corrosion resistance etc.; and molded products, fibers, films or foam materials can be obtained by extrusion, injection molding, etc., and have good processing performance, and are widely used in aerospace, medical, electrical and electronic, chemical and other fields. [0003] The above-mentioned types of resins usually use the raw materials to form a reaction solution by polycondensation reaction. This kind of polycondensation reaction usually needs to use a high-boiling point solvent as the reaction me...

Problems solved by technology

During this working process, because the solid particles have a certain viscosity, the clogging of the granulator often occurs, not only the granulation effect is poor, but also the normal production is affected
