Further, described nonmetal detection pipeline is earthenware duct or macromolecular material pipeline.
Further, described nonmetal detection pipeline and feeding tube are obliquely installed, and the angle between nonmetal detection pipeline and feeding tube is 135-160 °.
Compared with prior art, the utlity model has following beneficial effect:
First, the utility model is provided with metal detector at nonmetal detection pipeline section, after the coil detection head energising around of nonmetal detection pipeline section, produce induced field, when metallic foreign body passes through, cutting magnetic line produces induced-current, by induced-current, can detect at once whether have metallic foreign body.When metal detector detects metallic foreign body, by control system, automatically close stop valve simultaneously.
The second, the utility model is provided with look flashing light around at drying device, when metal detector detects metallic foreign body, by control system, provides signal to look flashing light, and look flashing light is reported to the police.
The 3rd, the utility model main feature be rational in infrastructure, drying effect good, not limited by regenerative piece of polyester bottle metal impurities.Once pick-up metal impurity in regenerative piece of polyester bottle, described drying device can carry out online the detection with timely of metal impurities in good time isolates, efficiently solve the metal impurities problem occurring in dry run, avoid damage or other accidents of production equipment to occur, met the production requirement of regenerative piece of polyester bottle final products.
Accompanying drawing explanation
Fig. 1 is that the utility model is with the structural representation of the drying device for regenerated polyester bottle flakes of metal detector;
In figure: 1 wet bottle chips storehouse, 2 tremie pipes, 3 stop valves, 4 metal detectors, 5 pre-crystallizers, 6 drying towers, 7 dry bottle chips storehouses.
The specific embodiment
As shown in Figure 1, a kind of drying device for regenerated polyester bottle flakes with metal detector, comprises wet bottle chips storehouse 1, tremie pipe 2, pre-crystallizer 5, drying tower 6, dry bottle chips storehouse 7, stop valve 3, metal detector 4.
Wet bottle chips storehouse connects pre-crystallizer by tremie pipe, and pre-crystallizer connects drying tower by pipeline, and drying tower connects dry bottle chips storehouse by pipeline.
Stop valve is arranged on tremie pipe, and metal detector is arranged between stop valve and pre-crystallizer.Stop valve is used for controlling regenerative piece of polyester bottle discharge quantity.
Above-mentioned drying device also comprises controller, alarm and nonmetal detection pipeline.Metal detector connects stop valve by controller.Alarm connects described metal detector by described controller.Nonmetal detection pipeline upper end is connected with tremie pipe, and nonmetal detection lower end of duct is connected with described pre-crystallizer, on nonmetal detection pipeline, metal detector is set.
