Abstract
The utility model discloses a polyvinyl pyrrolidone polymerization reactor, which mainly comprises a polymerization reactor body provided with a jacket, a stirring shaft and a stirring blade which are arranged in the polymerization reactor body; a guide cylinder is arranged on the periphery of the stirring shaft and the stirring blade; the guide cylinder is fixedly connected with the inner wall of the polymerization reactor body; the guide cylinder adopts a cylinder shape, the upper part and the lower part thereof are communicated with each other, and circular holes with identical diameter are evenly distributed on the wall of the guide cylinder. The polymerization reactor ensures that the materials are evenly mixed; the reaction is sufficient; the production of the side products such as jelly cross linked products is reduced; the monomer content of NPT raw material in the polymer fluid is reduced, thereby fully improving the product quality; and the utility model has the advantages of simple structure, easy modification, and convenient operation.
Description
Technical field
The utility model relates to a kind of polymer organic polymer device, especially relates to a kind of polymeric kettle.
Background technology
Existing polymerizer equipment, for making mixing of materials even, the main structure that agitator is set in the polymerization kettle that adopts, though the polymeric kettle of this mechanism can satisfy the needs of general reaction hybrid reaction, but when the polyvinylpyrrolidone polymerization, owing to be subjected to the restriction of material, temperature, time, stir inhomogeneous, abundant, raw material can not complete reaction between polymerization period, cause by products such as cross-linking agent too much, had a strong impact on the quality of polyvinylpyrrolidone, some cross-linking agents are bonded on the agitator easily, increased and stirred the resistance that rotates, also influenced mixing effect.
Summary of the invention
For solving above the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and stirs, polyreaction is abundant, can significantly improve the polymeric kettle of polyvinylpyrrolidone quality.
Technical solutions of the utility model are:
A kind of polyvinylpyrrolidone polymeric kettle of the utility model, mainly comprise the polymerization kettle that has chuck, be arranged at intravital stir shaft of still and agitating vane, one guide shell is set around described stir shaft and the agitating vane, and the stainless plate of both ends or one end and inner wall of kettle connect firmly and connect guide shell up and down by being arranged on guide shell;
Described guide shell is cylindric, communicates up and down;
The circular hole of uniform distribution equal diameters on the barrel of described guide shell.
Described guide shell be certain diameter, highly, the cylindrical shell of wall thickness, in order better to make and to install, preferably guide shell is installed in the bottom of still, give full play to its performance in order to make guide shell, stir shaft and stirring blade are installed in the bottom of guide shell inside.
The beneficial effects of the utility model:
By in kettle, settling a guide shell, when stirring, the material of kettle inner chamber enters guide shell from the guide shell lower end, flow out from the upper end or the sidewall of guide shell, can make mixing of materials even, sufficient reacting reduces by product generations such as jelly cross-linking agent, reduce the monomeric content of raw material NVP in the polymer fluid, thereby fully improve the quality of product.Simultaneously, the utility model also has simple in structure, repacking easily, easy to operate advantage does not change other structure of polymeric kettle, installs a guide shell additional and gets final product.
This polymeric kettle can be used as intermittent type or continous way polymerization reactor.Its internal structure has determined that this reactor has bigger effective reaction space, is applicable to the polymer organic polymer, and its range of application and throughput are higher; Be not only applicable to gas-solid state reaction, also applicable to liquid-solid phase, liquid-liquid phase reaction, and gas-liquid-solid phase reaction, this polymeric kettle is fit to the most is polymerization reactor as the N-vinyl pyrrolidone.
Description of drawings
Fig. 1 is the structural representation of a kind of polyvinylpyrrolidone polymeric kettle of the utility model;
Among the figure: 1, polymerization kettle; 2, stir shaft; 3, agitating vane; 4, guide shell.
Embodiment
As shown in Figure 1: a kind of polyvinylpyrrolidone polymeric kettle, mainly comprise the polymerization kettle 1 that has chuck, be arranged in the kettle 1 stir shaft 2 and agitating vane 3, around described stir shaft 2 and the agitating vane 3 guide shell 4 is set, stainless plate and the inner wall of kettle of guide shell by being arranged on guide shell two ends about in the of 4 connects firmly and connects, guide shell 4 is cylindric, communicates the circular hole of uniform distribution equal diameters on the barrel up and down.
Guide shell 4 be certain diameter, highly, the cylindrical shell of wall thickness, this guide shell is installed in the bottom of still, stir shaft and stirring blade is installed in the bottom of guide shell inside.
