Reaction kettle for producing static material not easy to flow and use method thereof

Abstract

The invention discloses a reaction kettle for producing a static material not easy to flow and a use method thereof. The reaction kettle comprises a kettle body and a driving motor which is installed at the upper part of the kettle body; a rotary shaft of the driving motor is connected with a rotary shaft equipped with an anchor agitator; the rotary shaft is a screw agitator which is provided with a spiral blade, the lower end of the screw agitator is connected with a tapered screw, and the shape of a tapered blade of the tapered screw is adapted to that of a reversed taper at the bottom of the kettle body. According to the reaction kettle provided by the invention, upward or downward axial force can be generated through changing the rotation direction of a rotary screw and the materials can be sufficiently mixed and reacted in the reaction phase, so that the molecular weight distribution range of products is not wide, the quality of the products is improved, the discharging efficiency is guaranteed in the discharging phase, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the field of biopharmaceuticals, and in particular relates to a reactor for producing materials that are static and difficult to flow and a method for using the same. Background technique [0002] During the polymerization reaction process, as the reaction proceeds, the viscosity of the polymer continues to increase, especially in the process of producing liquid crystals, whenever the reaction process progresses, the degree of polymerization increases, and the viscosity also increases. The fluidity is very good, but when the viscosity increases to a certain level in the static state, it hardly flows, and some liquid crystal polymers will still be muddy, and the material cannot be released. In order to overcome this defect, the currently adopted process is to discharge the material at a lower viscosity, and then carry out solid-phase viscosification to increase the viscosity. The liquid crystal macromolecule prepared by this me...

Problems solved by technology

However, in the process of processing and producing liquid crystals, the device described in this patent still has insufficient reaction caused by uneven stirring and mixing, which makes the molecular distribution of liquid crystal polymers wide and unstable, thereby affecting product quality; and its stirring device Not very efficient at outfeed
