Description
Technical field
The utility model relates to the equipment that uses in a kind of rubber production, is specifically related to a kind of device that is used to reclaim the residual monomer of rubber building-up process.
Background technology
Rubber is made rubber cement through letex polymerization or solution polymerization by starting monomer usually in polymeric kettle, make finished product through processing such as cohesion, dryings then, and unreacted monomer remains in the rubber cement with the free form in the polymeric kettle.In order to reduce the residual of monomer and raw material in the finished product, to improve the quality of products; In order to improve utilization ratio of raw materials and transformation efficiency, need unreacted monomer is recycled simultaneously.
Existing MONOMER RECOVERY technology mainly contains two kinds: a kind of is to carry out in polymeric kettle, specifically be exactly to add the terminator termination reaction after polymerisation conversion acquires a certain degree, rubber cement after the termination vacuumizes earlier removes the part residual monomer, rubber cement carries out flash distillation after being heated to certain temperature under vacuum condition then, so just can remove the remaining reaction monomers of the overwhelming majority, will classify by the monomer that polymeric kettle is deviate from then and reclaim and handle; Because the heating surface area and the evaporation area of material are limited, its processing speed is slower.Another kind of technology is that the material after the polymerization is fed degassing tower, residual monomer is removed in material flash distillation in degassing tower, then the monomer classification of being deviate from is reclaimed, in this technology, material in the polymeric kettle is sent in the degassing tower continuously, and this technology is that continous way reclaims technology; But because of the degassing tower complex structure, the tower body size is bigger in this technology, can cause the heat distribution inequality, causes local superheating, makes rubber bound, gel or putty, uses very inconvenient.
And all there is a very serious defective in two kinds of above-mentioned treatment process, that is exactly to wait until that residual monomer in the reaction system is all deviate from the post polymerization still and could be fed in raw material again and produce, and the process that reclaims residual monomer needs the long time, so just caused the monomeric operation of recovery will take polymeric kettle, the utilization ratio of polymeric kettle is lower, and the output and the production efficiency of a whole set of production line all are restricted.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, the material retrieving arrangement that can enhance productivity.
The scheme that adopts is exactly: a kind of material retrieving arrangement, comprise degassing still, degassing still is provided with the agitator that is used for material in the stirring tank, on the degassing still opening for feed and discharge port are set, venting port is offered on the top of degassing still, and venting port connects vapor pipe, and order is provided with retrieving arrangement and vacuum extractor on this vapor pipe, the still wall of degassing still is provided with interlayer, and the interlayer inner chamber is in communication with the outside by inlet tube and outlet tube.
As shown from the above technical solution: material is after polymerization is finished in polymeric kettle, be put into immediately in the degassing still, in degassing still, add terminator then and stop polyreaction, utilize degassing still under agitation condition, material to be carried out flash distillation, monomer residual in the material can be extracted out and collected in the retrieving arrangement, so just realized the recovery of the residual monomer of reaction system, the residual monomer after the recovery can be classified and be handled and recycle; Because the volume and the flash-off time of degassing still can be adjusted according to the processing requirement of flash distillation, the utility model reclaims monomeric better effects if; The structure of degassing still is also simple than degassing tower, uses more convenient; And after the material in the polymeric kettle was put into degassing still, in the process of utilizing degassing still flash distillation material handling, polymeric kettle can feed in raw material simultaneously and carry out polyreaction, and the utilization ratio of polymeric kettle improves like this, and the production efficiency of whole production line and output can improve greatly.
