Abstract
The utility model relates to a final polycondensation kettle which comprises a power device, a shaft, a preformed polymer inlet and a final polymer outlet of a kettle body, a shaft seal and a shaft supporting device. The utility model is characterized in that a plurality of spacer plates are arranged at the lower part of an inner shaft of the kettle body, the spacer plates can cause a lower inner cavity of the kettle body to be divided into a plurality of chambers, some circular disks which are used for agitating and are perpendicular to the shaft are arranged on the inner shaft of the kettle body, and a shaft end support is arranged at the end part of the inner shaft of the kettle body. The utility model has the advantages that the stable operation is realized, the simple structure is realized, and the constant vacuum degree can be maintained, and a vacuum system is difficult to clog; thus, the quality of the final polycondensation is raised.
Description
The utility model relates to a kind of chemical industry equipment, exactly relates to a kind of whole polycondensation vessel.
The structure kind of terminal polymerization kettle is more both at home and abroad at present, but still there are some problems, for example operation is stable inadequately, the thermal expansion of shaft and cylindrical shell is variant, cause that easily shaft end axle envelope lost efficacy, vacuum is difficult for keeping, and easily makes vacuum system obstruction etc., and this all will bring quality problems to final product.
The purpose of this utility model is exactly the shortcoming that overcomes present terminal polymerization kettle, and a kind of whole polycondensation vessel of stable operation is provided, and this, polycondensation vessel can make the product quality of formation be improved at end.
The purpose of this utility model realizes by following technical proposals, whole polycondensation vessel of the present utility model comprises power set axle, kettle, the prepolymer import of kettle and the outlet of whole polymers, the axle bracing or strutting arrangement, wherein the bottom of axle is provided with several dividing plates in the kettle, these dividing plates are divided into a plurality of chambers with the kettle lower inner cavity, and the axle in the kettle is provided with the disk perpendicular to axle that some are used to stir, and the end of axle is provided with the axle head support in kettle.
Another preferred mode of the present utility model is the intermediate supports that the place, centre position of axle in kettle is provided with axle.
Another preferred mode of the present utility model is the top, side that steam (vapor) outlet is arranged on kettle, and adds baffled in the still in exit.
Prepolymer enters kettle by its import, stirs through disk, and each indoor material is elevated by disk and forms thin film, (EG) steam is overflowed under condition of high vacuum degree, product viscosity increases gradually, discharge from its outlet at last, and (EG) steam is discharged from steam (vapor) outlet.
Technological merit of the present utility model
1, this terminal polymerization kettle whole process is provided with the disk perpendicular to axle, when disk rotates, produces bigger bath surface, and make material keep piston flow, owing to dividing plate terminal polymerization kettle has been divided into a plurality of chambers again, and has had the breach of definite shape on the dividing plate, thereby made material stream passed not stay the dead angle.
2, because the tip of the axis props up and stays in the still, make the shaft end bad seals, cause the problem that vacuum is difficult to guarantee in the still so thoroughly solved because of axle is different with the cylindrical shell thermal expansion.
3, because the middle part of axle is provided with support, thus make amount of deflection obtain effective control than major axis, thus make lengthening terminal polymerization kettle flow process become possibility.
4, the EG steam (vapor) outlet is arranged on the side, and has added baffle plate in the exit, thereby has prevented that the EG that terminal polymerization kettle steams is entrained with condensation polymer and stops up vacuum system.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is the schematic diagram of terminal polymerization kettle of the present utility model.
Referring to accompanying drawing, terminal polymerization kettle of the present utility model comprises power set 1, axle 2, kettle 3, the prepolymer import a of kettle and whole polymers outlet b, axle envelope 4, the bottom of axle 2 is provided with several dividing plates 5 in kettle 3, and these dividing plates 5 are divided into a plurality of chambers with kettle 3 lower inner cavities, as shown in the figure, axle 2 in the kettle 3 is provided with some disks that are used to stir 6, and the end of axle 2 is provided with axle head and supports 7 in kettle; In addition can be in kettle 3 place, centre position of axle 2 be provided with the intermediate supports 8 of axle; Be provided with (EG) steam (vapor) outlet 9 on the top, side of kettle 3, and in this exports the kettle at 9 places, add baffled 10.
Claims (3)
1, a kind of novel whole polycondensation vessel, it comprises the prepolymer import and the outlet of whole polymers of power set, axle, kettle, axle envelope and bearing device, the bottom that it is characterized in that axle in described kettle is provided with several dividing plates, these dividing plates are divided into a plurality of chambers with the kettle lower inner cavity, on the axle disk perpendicular to axle that some are used to stir is set in kettle, the end of axle is provided with the axle head support in kettle.
2, whole polycondensation vessel according to claim 1 is characterized in that the place, centre position of axle in kettle is provided with the intermediate supports of axle.
3, ask according to power and require 1 described whole polycondensation vessel, it is characterized in that being provided with steam (vapor) outlet, and in the still of exit, add baffled on the top, side of kettle.
