The utility model discloses a reation kettle inserts the design in the rotary drum alone through the nitrogen gas intake pipe, can guarantee that vacuum tube says with to fill the nitrogen gas pipeline isolated completely, makes the material tackifies in the reaction modes of leading to nitrogen gas that rely on in earlier stage more to the deposit is in order to block the pipeline in the pipeline when the evacuation to avoid in the rotary drum a large amount of low molecules that produce and small -size's powder, and the mode of later stage through the evacuation makes oligomer solid phase tackify complete, reduce cost when can improve the yield of product like this.
Description
Technical field
The present invention relates to a kind of reactor of solid-phase tack producing, being specifically related to a kind of reactor of the solid-phase tack producing for easily playing powder in course of reaction.
Background technology
When producing special engineering plastics, the normal method adopted is for first to prepare oligomer at present, again by oligomer solid-phase tack producing, but high-temperature nylon and liquid crystal etc. can produce a large amount of undersized powders when oligomer being made suitable dimension and carrying out solid-phase tack producing, thickening is vacuumized because usual rotary drum adopts, thus usually can be extracted out by high vacuum together with the low molecule generated when these undersized powders join solid-phase tack producing in rotary drum, undersized powder containing oligomer of mixing can be deposited in the pipeline of vacuum-pumping tube, cause pipeline obstruction, cannot thickening further, material its colour changed into yellow can be caused simultaneously.
Chinese patent 200810024815.8 discloses a kind of small solid-phase tack producing device and using method thereof, its method is, by polyester slice by charge door access arrangement, and after being heated to uniform temperature, make section start polycondensation reaction, and discharge with low-molecular material, the lower-molecular substance that course of reaction produces is discharged from charge door or vaccum exhaust outlet with nitrogen, its advantage is, it is low that product stablizes energy consumption, but its deficiency is, is only applicable to a small amount of production and large-scale industrial circle can not be applied to.
The scheme of current solution is generally adopt to be screened out by powder before thickening in rotary drum; but oligomer and still wall friction and collide each other and still can produce certain dust before viscosity does not get on; certain influence is had to rotary drum solid-phase tack producing; and screening out undersized powder can cause waste excessively, improve product cost.
Summary of the invention
In order to overcome above-mentioned prior art problem, the purpose of this utility model is the reactor providing a kind of solid-phase tack producing, and this reactor can reduce dust and micromolecular quantity in reactor greatly, effectively avoids the line clogging caused by dust deposit.
The utility model is achieved through the following technical solutions:
A kind of reactor of solid-phase tack producing, comprise rotary drum, rotary drum is provided with charge door and manhole, the outer side joint rotating ring of rotary drum, inner turnover tracheae connects stationary ring, one end of vacuum-pumping tube is stretched in rotary drum, and the other end connects vavuum pump, and the mouth of pipe of vacuum-pumping tube is positioned at rotary drum top, the mouth of pipe of vacuum-pumping tube is provided with filter mantle, one nitrogen inlet duct stretches in rotary drum, and the output of nitrogen inlet duct is positioned at bottom of the drum, nitrogen inlet duct and vacuum-pumping tube relatively independent.
Logical nitrogen thickening is adopted when solid-phase tack producing reaction has a large amount of low molecule to produce in earlier stage, temperature, the time of logical nitrogen are determined by the smoke discharging volume of nitrogen outlet, a large amount of dust can not be taken out of from gas outlet with normal temperature and be advisable by nitrogen throughput, adopts again vacuumize thickening when the low molecule of solid-phase tack producing reaction later stage generation is little.
In order to avoid the material in rotary drum is taken away by vacuum system in a large number vacuumizing in thickening process, the mouth of pipe of vacuum-pumping tube of the present utility model is provided with filter mantle.
Preferably, the input of nitrogen inlet duct is provided with a valve, is also provided with a valve between vacuum-pumping tube and vavuum pump.
Preferably, a separator and a cold-trap is provided with between vacuum-pumping tube and vavuum pump.
Preferred, described separator is cyclone separator.
The utility model compared with prior art, has following beneficial effect:
Nitrogen inlet duct and the vacuum-pumping tube of the utility model reactor are relatively independent, the design in rotary drum is inserted separately by nitrogen inlet duct, can ensure vacuum lead and inflated with nitrogen pipeline completely isolated, the mode that nitrogen is led in phase many dependence before the reaction makes material thickening, deposit in the duct to block pipeline when vacuumizing with the low molecule and undersized powder of avoiding a large amount of generation in rotary drum, later stage makes oligomer solid-phase tack producing complete by the mode vacuumized, and reduces costs while can improving the yield of product like this.
Accompanying drawing explanation
Fig. 1 is the reactor structural representation of the utility model solid-phase tack producing.
