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 [0001] The invention relates to the field of polyester production equipment, in particular to a feeding device for an esterification reaction kettle. Background technique [0002] In the polyester production process, PET raw materials and alcohol are sent into the esterification reaction tank for esterification reaction, and then the PBT finished product is obtained after the pre-shrinking tank and the final shrinking tank. At present, in the polyester production process, the PET raw material is usually first heated to a molten state, and then added to the esterification reactor together with the alcohol. The alcohol and the PET raw material are first subjected to alcoholysis, and then the esterification reaction, which leads to The process takes a long time, which reduces the efficiency of the output. Contents of the invention [0003] The object of the present invention is to provide a feeding device for an esterification reaction tank to solve the probl...
