Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a glass bead sample forming apparatus for performing optical analysis, for example, by irradiating an X-ray and detecting the wavelength of the fluorescent X-ray.

(Prior Art) A sample for optical analysis that irradiates X-rays and detects the wavelength of the fluorescent X-rays is extremely uniform as a whole, has different components depending on the position, or reflects depending on the irradiation direction of light. It requires that the light does not make a difference.
Therefore, when forming a glassy sample, conventionally, a crucible containing a raw material was placed in a furnace and the entire furnace was swung or rotated.

However, since such an apparatus moves a large and heavy furnace, it has a drawback that the apparatus is very large and heavy and expensive. Further, if the sample melted in the furnace is taken out of the furnace and injected into another container to obtain a sample having a certain shape and size, bubbles are easily mixed in the sample and the operation is complicated.

Therefore, conventionally, a crucible containing the raw material of the glass beads, a support rod (vertical rod) that penetrates the furnace wall and supports the crucible, and a crucible that moves outside the furnace body by driving the crucible There is known a glass bead manufacturing apparatus provided with a manipulating machine (see Japanese Utility Model Publication No. 58-137437).

(Problems to be solved by the invention) However, in this prior art, it is not possible to give a sufficient movement necessary for stirring and mixing the sample, and it is possible to give a sufficient movement to the crucible to release the gas. Can not. That is, in the above-mentioned prior art, since the upper part of the crucible is open, when the sample is sufficiently agitated and mixed and the gas is sufficiently released, that is, when the crucible is given an upside down or a large rocking motion, Sample runs through. Therefore, it is conceivable to provide a lid on the crucible and seal the crucible at all times during rotation. However, this increases the gas pressure in the crucible and hinders gas release.

The present invention has been made in view of the above conventional problems, and provides a glass bead forming apparatus capable of giving sufficient movement to a crucible to sufficiently mix a sample and releasing gas. It is an object.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object will be described. The glass bead forming apparatus of the present invention comprises a crucible having a flange on the outer circumference for accommodating the raw material of the glass bead, a pair of support rods penetrating the furnace wall to support the crucible, and the above-mentioned support provided outside the furnace body. And a manipulator that gives movement to the crucible by driving a rod. Further, the glass bead forming apparatus includes a lid plate that closes the opening of the crucible, and the supporting rod has a base end connected to the operating machine, and one supporting rod with respect to the other supporting rod. , A gripping part for supporting the flange of the crucible is provided at the tip of the other supporting rod at the tip of the other supporting rod, and is provided at the tip of the one supporting rod of the crucible. Gripping portions for pressing the lid plate superposed on the flange against the flange are respectively provided, and further, the supporting portions are engaged with each other when the one supporting rod advances into the crucible. Between the flange and the cover plate,
Hooks are provided to release the above-mentioned clamping when one of the support rods retracts.
