Abstract
The invention relates to a feeding device for an esterification reactor. The feeding device comprises a barrel, wherein one end of the barrel is provided with a feeding hopper, the bottom of the feeding hopper is connected with the barrel, the upper part of the feeding hopper is provided with a PET (polyethylene terephthalate) bottle piece inlet, the side part of the feeding hopper is provided with an ethanol feeding pipe, and the other end of the barrel is provided with a discharging port; and a screw rod is arranged in the barrel, a screw rod driving device is arranged outside the barrel, and a heating device is arranged on the wall of the barrel. The feeding device for the esterification reactor adopts the mode of screw rod extrusion by feeding PET bottle pieces and ethanol together at the feeding port, so that the melting of PET bottle pieces as well as alcoholysis in advance is achieved in the barrel, the alcoholysis time in the esterification reactor is shortened, and the output efficiency is improved.
Description
Technical field
The present invention relates to the polyester production facility field, refer to a kind of pay-off of reaction kettle of the esterification especially.
Background technology
In polyester production process, PET raw material and alcohol are admitted to together and carry out esterification in the reaction kettle of the esterification, behind preshrunk still and final minification still, obtain the PBT finished product then.At present in polyester production process, usually at first the PET raw material is heated to molten condition, and then join in the reaction kettle of the esterification together with alcohol, pure and mild PET raw material at first carries out alcoholysis, and then carry out esterification, thereby cause whole process to need the long period, thereby reduced the efficient of output.
Summary of the invention
Technical problem to be solved by this invention is: a kind of pay-off that can shorten the reaction kettle of the esterification of production time is provided.
For addressing the above problem, the technical solution used in the present invention is: the pay-off of reaction kettle of the esterification, comprise a machine barrel, an end of machine barrel is provided with feed hopper, and the bottom of feed hopper is connected with machine barrel, the top of feed hopper is PET bottle sheet feeding mouth, the sidepiece of feed hopper is provided with pure feed pipe, and the other end of machine barrel is discharging opening, is provided with screw rod in the machine barrel, the machine barrel outer setting has spiro driving device, and the barrel of machine barrel is provided with heater.
Described spiro driving device is motor.
Described heater is the electric heating sheets that is arranged on the barrel of machine barrel.
The invention has the beneficial effects as follows: the pay-off of above-mentioned reaction kettle of the esterification, the mode that it adopts screw rod to extrude, charging aperture is transformed into PET bottle sheet and alcohol charging together, can in machine barrel, not only realize the thawing of PET bottle sheet but also can realize alcoholysis in advance like this, shorten the time of alcoholysis in the reaction kettle of the esterification, improved the efficient of output.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1, machine barrel, 2, feed hopper, 3, PET bottle sheet feeding mouth, 4, pure feed pipe, 5, discharging opening, 6, screw rod, 7, motor, 8, electric heating sheets.
The specific embodiment
Be described in further detail below by the pay-off of specific embodiment to reaction kettle of the esterification of the present invention.
As shown in Figure 1, the pay-off of reaction kettle of the esterification, comprise a machine barrel 1, one end of machine barrel 1 is provided with feed hopper 2, the bottom of feed hopper 2 is connected with machine barrel 1, the top of feed hopper 2 is PET bottle sheet feeding mouth 3, the sidepiece of feed hopper 2 is provided with pure feed pipe 4, the other end of machine barrel 1 is discharging opening 5, is provided with screw rod 6 in the machine barrel 1, and machine barrel 1 outer setting has spiro driving device, spiro driving device is motor 7 in the present embodiment, the barrel of machine barrel 1 is provided with heater, and in the present embodiment, described heater is the electric heating sheets 8 that is arranged on the barrel of machine barrel 1.
The pay-off of above-mentioned reaction kettle of the esterification, during its work, PET bottle sheet is put into from PET bottle sheet feeding mouth 3, and simultaneously alcohol is sent into from pure feed pipe 4, the fusion under the heating of electric heating sheets 8 of PET bottle sheet, and under the effect of machine barrel 1 inner screw 6, be fed forward, simultaneously with alcohol generation alcoholysis, thereby shortened the time of alcoholysis in the reaction kettle of the esterification, improved the efficient of output.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
