Abstract
The invention discloses a material conveying device of an esterification reaction kettle. The material conveying device comprises a motor, an alcohol material inlet, a PET (polyethylene glycol terephthalate) bottle chip inlet, a material feeding hopper, an electric heating sheet, a helical blade, a screw rod blade, a screw rod, a reversal joint, a material outlet, a base, a machine barrel, a motor and a stirring paddle, wherein the material feeding hopper is of a barrel-shaped structure; the alcohol material inlet and the PET bottle chip inlet are formed in the side part of the material feeding hopper; the motor is arranged on the top of the material feeding hopper and is connected with the stirring paddle; the material feeding hopper is mounted at one end of the machine barrel; the screw rod is arranged in the machine barrel; one end of the machine barrel is connected with the reversal joint; the reversal joint drives the machine barrel and the screw rod to rotate oppositely, and the motor and the stirring paddle mix materials at the alcohol material inlet and the PET bottle chip inlet in advance; the reversal joint enables the machine barrel to rotate oppositely to the screw rod; the opposite rotations of the helical blade and the screw rod blade, full mixing and reaction of the materials are enhanced; by the use of the electric heating sheet, the time for alcoholysis in the esterification reaction kettle is shortened.
Description
Technical field
The present invention relates to polyester production facility field, specifically a kind of pay-off of reaction kettle of the esterification.
Background technology
In polyester production process, PET raw material and alcohol are admitted to together in reaction kettle of the esterification and carry out esterification, then, after preshrunk still and final minification still, obtain PBT finished product.At present in polyester production process, conventionally first by PET heating raw materials to molten condition, and then join in reaction kettle of the esterification together with alcohol, first alcohol and PET raw material carry out alcoholysis, and then carry out esterification, thereby cause whole process to need the long period, thereby reduced the efficiency of output.
Summary of the invention
The object of the present invention is to provide a kind of pay-off of reaction kettle of the esterification, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of pay-off of reaction kettle of the esterification, comprise motor, alcohol charging aperture, PET bottle sheet feeding mouth, feed hopper, electric heating sheets, helical blade, screw rod blade, screw rod, reversion joint, discharging opening, base, machine barrel, motor and paddle, described feed hopper is tubular structure, the sidepiece of feed hopper is provided with alcohol charging aperture and PET bottle sheet feeding mouth, motor is equipped with at the top of feed hopper, motor is connected to paddle, described paddle has stirring action to the charging of alcohol charging aperture and PET bottle sheet feeding mouth, feed hopper is arranged on one end of machine barrel, machine barrel is arranged on base, in machine barrel, be provided with screw rod, screw rod one end is provided with motor, the other end is provided with discharging opening, described motor is the drive unit of screw rod, the rotation of driven by motor screw rod, on screw rod, be fixed with screw rod blade, the barrel inside of machine barrel is fixed with helical blade, described helical blade and screw rod blade rotary opposite direction, and one end of machine barrel connects reversion joint, rotate contrary with screw rod of reversion laced belt motivation cylinder.
As the further scheme of the present invention: the barrel outer setting of described machine barrel has electric heating sheets.
Beneficial effect of the present invention is: motor and paddle mix in advance to the material of alcohol charging aperture and PET bottle sheet feeding mouth, reversion joint makes machine barrel to screw rod counter-rotation, helical blade has increased fully mixing and reaction of material with the opposite spin of screw rod blade, electric heating sheets has shortened the time of alcoholysis in reaction kettle of the esterification.
