Problems solved by technology
[0004] The purpose of the present invention is to solve the problem in the prior art that "because the feed inlet of the modifier is small, it often needs to be added by means of a funnel, but the drop point of the modifier is unchanged, and the contact with the reactant is not sufficient, so it often needs to be added." With the help of the self-stirring function of the kettle body to fully stir and disperse, the time required for stirring delays the polyester modification reaction time, and the production efficiency is low", and a feeding mechanism for the polymerization reaction device is proposed

The invention discloses a feeding mechanism of a polymerization reaction device. The feeding mechanism includes: an air inlet pipe fixed at the output port of a blower, the rotation of the bottom end of the air inlet pipe is connected with a connecting pipe, and the rotating There is a modifier feed pipe connected to it, the modifier feed pipe is set through the air inlet pipe, and the bottom end of the air inlet pipe is provided with a plurality of air inlet holes; the axial flow impeller, the axial flow impeller is fixed Interspersed on the communication pipe, the communication pipe and the air inlet pipe are arranged concentrically; the nozzle, the nozzle is rotatably connected to the outer wall of the air inlet pipe, and the nozzle is fixedly connected to the communication pipe through the connecting rod. The invention controls the speed of the axial flow impeller by controlling the air intake of the blower, that is, controls the speed of the nozzle. When the speed of the nozzle is faster, the outlet section of the discharge hole increases gradually, thereby increasing the spraying of the modifier. The range greatly improves the dispersion effect and reduces the time required for stirring by the tank agitator.
Description
technical field [0001] The invention relates to the technical field of modified polyester, in particular to a feeding mechanism of a polymerization reaction device. Background technique [0002] The chemical modification of polyester is carried out during the synthesis process. In addition to the basic monomers, the third and fourth monomers are added to change the macromolecular structure in order to achieve the purpose of improving some physical and chemical properties. Polyester The physical modification of the polymer is carried out during the polymer forming process, that is, during the spinning process. Generally, the method of blending is adopted, and chemical modification and physical modification not only rely on each other in implementation, but also have many commonalities in mechanism. [0003] In the middle stage of the polyester reaction, the ethylene glycol mixed solution of the modifier needs to be added, but because the feed port of the modifier is small, i...
