Detailed description of the invention
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
embodiment 1
As shown in Figure 1, vertical response still, comprises vertical housing 1, is fixed with a stirring rod 2 with paddle 21 within the case 1, and stirring rod 2 is connected with motor 3 axial seal at housing 1 top.The top of housing 1 is provided with feed pipe 11, discharge nozzle 12 is arranged at bottom and there is vacuum pumping opening 4 at sewage draining exit 16, middle part.There is at housing 1 sidewall the cavity (not shown) depositing conduction oil, the heating rod 52 of heating conduction oil is installed in bottom, above sidewall, (top of cavity) is provided with one for adding the heat-conducting oil pipes 51 of conduction oil, is detachable elbows 511 at the tail end of heat-conducting oil pipes 51; When needs add conduction oil, remove the elbow 511 above heat-conducting oil pipes 51, the feed end of heat-conducting oil pipes 51 is straight up; In heating process, heat pipe 51 must install elbow 511, and this heat-conducting oil pipes 51 is just used as the exhaust outlet of conduction oil, in the below of elbow 511, place a gob barrel 53, the material of the generation gas of recoverable conduction oil, also can maintain the neat and tidy of factory.Also have the inspection socket 17 entered for people at the top of housing 1, convenient for maintaining personnel enter internal check maintenance.For convenience of extensive maintenance, housing 1 is divided into two sections, by bolt 18 fixing seal between two sections.Except above structure, housing 1 also includes the necessarieses such as thermometer, pressure gauge, liquid level gauge, visor.
As illustrated in fig. 1 and 2, Multi-layer annular material disc 6 is fixedly connected with in the middle and upper part of described stirring rod 2, be uniformly distributed multi-through hole 61 at material disc 6, its outer edge is provided with the flange 62 of 1-2cm, and successively more and more less external diameter is then increasing for the internal diameter of material disc 6 from top to bottom; The discharge end of described feed pipe 11 should be positioned at the top of material disc 6.Further, two vacuum pumping opening 4 being arranged on above the highest liquid level and being positioned at the below of minimum material disc 6, two vacuum pumping opening 4 are arranged about housing center line axial symmetry, improve the stability of this structure for vacuum.For preventing material from being overflowed by vacuum pumping opening 4, affecting the normal work of vavuum pump, just baffle plate 41 being installed with to vacuum pumping opening 4 place in housing 1 inside.For cleaning housing 1 inwall, above paddle 21 and the below of vacuum pumping opening 4 is fixed with scraper plate 22, end shrinking away from theshell body 1 inwall of scraper plate 22 only has 1cm.
The concrete use procedure of the present embodiment reactor:
Housing 1 internal vacuum of this reactor is set in 50-500pa, and temperature remains on 275-300 DEG C.
First, material (oligomer melt) is entered by top S type feed pipe 11.Feed pipe 11 is designed to S type and just requires that material must be accumulated to certain liquid level (existence of deaeration), and material just can be fallen on the material disc 6 of the bottom by the discharge end of feed pipe 11, is preferably just positioned at the top of the position of (internal diameter and external diameter)/2.Now, the rotation of material disc 6 also along with stirring rod 2 is rotating, fully ensures the homodisperse charging of material.
And then, under the effect of material disc 6, material can be dirty in material " rain " shape by dispersion, and due to the barrier effect of material disc 6, material dropping velocity is less than charging rate, when material is accumulated more than 1-2cm on material disc 6, will fall to next material disc 6 from the outer edge of material disc 6, under the effect of material disc 6, dispersion is material " rain " shape again; The like, successively dirty, finally arrive bottom with homogeneous material " rain " shape.Preferably, material disc 6 inward flange of the bottom is close to stirring rod 2, and outward flange is close to inner walls.The effect of this step, is the surface area strengthening material, improves devolatilization efficiency, reduce reaction time.
Material arrive housing 1 bottom can paddle 21 act under homogenizing polymerisation, the scraper plate 22 above paddle 21, except having self-cleaning function, can also stir material and make its homogenizing.
Finally, material is discharged from the discharge nozzle 12 of bottom, and discharge nozzle 12 is located at bottom and is ensured that material is first in first out, and the time of staying effectively controlling material is even, ensures the quality of finished product.
embodiment 2
As shown in Figures 2 and 3, the present embodiment is on the basis of embodiment 1, also be provided with the second feed pipe 13 at the top of housing 1, bottom is provided with the second discharge nozzle 14, second discharge nozzle 14 is connected to the second feed pipe 13 by a circulating pump 15, material is constantly circulated up and down, under the effect of material disc 6, repeatedly turn material one after another into rain and flow to bottom homogenizing polymerisation, further increase the surface area of material, improve the devolatilization efficiency of Small molecular oligomer and ethylene glycol, reduce reaction widely and stop required time.Meanwhile, can also ensure that within the scope of certain hour, realize material changes, and avoids partial material overstand, affects its quality.
Above-described, be only preferred embodiment of the present utility model, the scope that the utility model is implemented can not be limited, every equalization change of doing according to the utility model claim and decoration, all should still belong in scope that the utility model contains.
