Abstract
The utility model provides a caprolactam oligomer separating and conveying system, comprising an oligomer separator, a filter, a conveying gear pump, a depolymerization reactor, a first pipeline, a second pipeline and a third pipeline, wherein the lower end of the oligomer separator is connected to the inlet of the filter through the first pipeline; the outlet of the filter is connected to the inlet of the output gear pump through the second pipeline; and the outlet of the output gear pump is connected to the depolymerization reactor through the third pipeline. The caprolactam oligomer separating and conveying system is capable of reducing the frequency of stopping for replacement, improving the production efficiency and reducing the equipment maintenance cost.
Description
[technical field]
The utility model relates to a kind of hexanolactam oligomer and separates delivery system.
[background technology]
In " oligopolymer separation " workshop section of existing hexanolactam recovery part; hexanolactam oligomer etc. is being undertaken in the process of depolymerization by the depolymerizing reactor of conveyance gear pump delivery to next procedure by the oligopolymer separator; usually can produce because of the former of technology controlling and process thereby in the oligopolymer separator polymkeric substance macrobead of a large amount of infusibility high rigidity; this polymkeric substance macrobead can be with the conveyance gear pump seizure; in case this situation occurs, the component such as the mechanical seal that the conveyance gear pump was processed and changed to the stopping of production link long period that just will this part and bearing.Its replacement frequency is high, just must change once in 3 ~ 5 days, and high-frequency parking can affect normally carrying out of production, and production efficiency is reduced, and increases maintenance cost.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of hexanolactam oligomer to separate delivery system, can reduce the frequency of stopping and changing, and enhances productivity, and reduces the maintenance cost of equipment.
The utility model is achieved in that
A kind of hexanolactam oligomer separates delivery system, comprise an oligopolymer separator, a strainer, a conveyance gear pump, a depolymerizing reactor, one first pipeline, a second pipe and one the 3rd pipeline, the lower end of described oligopolymer separator is connected to the import of strainer by the first pipeline, the outlet of described strainer is connected to the import of conveyance gear pump by second pipe, and described conveyance gear pump outlet is connected to depolymerizing reactor by the 3rd pipeline.
Further, described strainer is arranged with an insulation jacket outward.
Further, described strainer is a basket filter.
The utility model has the advantage of:
The basket filter that arranges can filter the polymkeric substance macrobead interception of a large amount of infusibility high rigidity of producing in the oligopolymer separator, prevents that the polymkeric substance macrobead from entering the conveyance gear pump, causes the conveyance gear pump seizure; And only need regularly to stop and clear up and discharge the polymkeric substance macrobead that is detained in the filter basket of basket filter, shutdown period is short, has improved production efficiency; In addition, the frequency of changing and keeping in repair the conveyance gear pump can be reduced to 2 ~ 3 months once, greatly reduces the maintenance cost of equipment.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
[embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As shown in Figure 1, the related a kind of hexanolactam oligomer of the utility model separates delivery system, comprise an oligopolymer separator 1, a strainer 2, a conveyance gear pump 3, a depolymerizing reactor 4, one first pipeline 5, a second pipe 6 and one the 3rd pipeline 7, the lower end of described oligopolymer separator 1 is connected to the import of strainer 2 by the first pipeline 5, the outlet of described strainer 2 is connected to the import of conveyance gear pump 3 by second pipe 6, and the outlet of described conveyance gear pump 3 is connected to depolymerizing reactor 4 by the 3rd pipeline 7.
The described strainer 2 outer insulation jacket 21 that are arranged with; Described strainer 2 is a basket filter.
Use procedure of the present utility model is as follows: after oligopolymer separates in oligopolymer separator 1, the hexanolactam small molecules that obtains enters the first pipeline 5, the polymkeric substance macrobead is blocked filtration during again through basket filter 2, the hexanolactam small molecules continues to enter second pipe 6 from the outlet of basket filter 3, pumps to the 3rd pipeline 7 by conveyance gear pump 3 again and enters down in the depolymerizing reactor 4 of operation.
The basket filter 2 of the utility model setting can filter the polymkeric substance macrobead interception of a large amount of infusibility high rigidity of producing in the oligopolymer separator, prevents that the polymkeric substance macrobead from entering conveyance gear pump 3, causes conveyance gear pump 3 stuck; And only need regularly to stop and clear up and discharge the polymkeric substance macrobead that is detained in the filter basket (not shown) of basket filter 2, shutdown period is short, has improved production efficiency; In addition, the frequency of changing and keeping in repair the conveyance gear pump can be reduced to 2 ~ 3 months once, greatly reduces the maintenance cost of equipment.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
