Embodiment approach 1

[0045] Regarding the "presence or absence" of bromine in the following description, when bromine is contained in a certain proportion or more, it is expressed as bromine, bromine contained; Contains bromine. Below, the main reference figure 1 , figure 2 Details of Embodiment 1 of the present invention will be described.

[0046] figure 1 The sorting device 110 in Embodiment 1 of the present invention shown in figure 2 As also shown in , the measurement unit 100 for determining the presence or absence of bromine, which is a specific element, includes an X-ray source 1 that irradiates continuous X-rays 6 , a first filter 3 and a second filter 4 . It also includes an X-ray image intensifier as a first X-ray detector that detects the intensity of continuous X-rays 6 that are irradiated from the X-ray source 1 and sequentially pass through the first filter 3 and the resin sheet 2 that is the object to be sorted. 15. It also includes an X-ray image intensifier as a second X-...

Embodiment approach 2

[0086] In Embodiment 2 of the present invention, as Figure 11 As shown in the measurement unit 120 in the second embodiment, the first filter 3 and the second filter 4 are arranged on the lower side as the side where X-rays are detected as seen from the conveying device 7, and are irradiated from the X-ray source 1. The continuous X-rays 6 first pass through the resin sheet 2, and then pass through the first filter 3 and the second filter 4. The same effect can also be obtained by exchanging the permeation order of the filter and the resin sheet 2 in this way. In addition, by dividing one X-ray image intensifier 5 into two (for example, the right side and the left side of the drawing) and using one X-ray source 1, the cost of equipment investment can be reduced. The difference from Embodiment 1 of the present invention lies only in the above points.

Embodiment approach 3

[0088] In Embodiment 3 of the present invention, as Figure 12 As shown in the measurement unit 130 in the third embodiment, the motor 8 is attached to the first filter 3 and the second filter 4 so as to be rotatable. That is, the first filter 3 and the second filter 4 are rotationally moved. Thereby, the first filter 3 and the second filter 4 are alternately inserted between the X-ray source 1 and the resin sheet 2 . Therefore, the continuous X-rays 6 passing through the first filter 3 or the continuous X-rays 6 passing through the second filter 4 pass through the resin sheet 2 and can be detected by the X-ray image intensifier 5 . The difference from Embodiment 1 of the present invention lies only in the above points. In addition, the part where the first filter 3 and the second filter 4 are alternately inserted may not be between the X-ray source 1 and the resin sheet 2, but may be arranged between the resin sheet 2 and the X-ray sheet as in Embodiment 2 of the present in...

Abstract

The invention provides a separation device, a separation method and a manufacturing method by recycling resin materials, wherein a filter (3) containing bromine and a filter (4) containing an element having an X-ray absorption edge at an energy side higher than X-ray absorption edge of bromine, are used for detecting transmission intensity of continuous X-ray (6) irradiated on a resin sheet (2) after passing through the two filters (3, 4), and then precisely determining whether the resin sheet (2) contains bromine by means of the transmission intensity.

Description

technical field [0001] The present invention relates to a sorting device, a sorting method, and a manufacturing method of recycled resin materials when recycling objects, and particularly relates to a sorting device and a sorting device for sorting according to whether or not bromine is contained in the resin when recycling the resin. A method and a manufacturing method of a recycled resin material using the above-mentioned sorting method. Background technique [0002] The RoHS Directive of the EU came into effect in July 2006. Mercury, cadmium, lead, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) became restricted substances. Accompanied by this, when recycling electrical and electronic products, it is possible to easily determine the presence or absence of PBB and PBDE contained in resin sheets obtained by crushing products, especially PBB and PBDE used as bromine-containing flame retardants Development becomes important. ...
