Description

Technical Field

[0001] The present application mainly relates to the field of fusion machine equipment, and in particular to a fusion machine. Background Art

[0002] In X-ray fluorescence spectroscopy analysis, the glass melting sample preparation technology can effectively reduce or even eliminate the sample's particle effect, matrix effect, mineral effect and other adverse factors, greatly improving the accuracy of X-ray fluorescence spectroscopy analysis.

[0003] High-frequency melting machine is a commonly used method for making glass melts. Compared with electric melting machines, it has the advantages of high efficiency, fast speed, no need for preheating, and ready to use, and is gradually favored by the majority of users. The working principle of the high-frequency melting machine is to place the crucible containing the sample in an induction coil to heat and melt the sample. In order to pour the molten sample in the crucible into the mold to form a melt, the induction coil will be installed on a rotating mechanism. The rotating mechanism drives the coil to rotate a certain angle to pour the sample in the crucible into the mold. In order to prevent the crucible from falling off the induction coil, the usual practice is to design a ceramic bracket, the crucible is clamped with the bracket, and the induction coil is fastened to the bracket, such as 5 and Figure 6 As shown. A snap connection is provided on the mating surface of the ceramic bracket and the crucible. The crucible 50 has an ear piece 51 on the outside, and there is a notch on the ear piece (which can be snapped). The notch on the ear piece 51 is aligned with the snap connection 13 to place the crucible 50 into the bracket 11. Then the crucible is rotated, and the crucible can be fixed on the ceramic bracket. Even if it is rotated, the crucible will not fall off. The ceramic bracket is used to fix the crucible because of the particularity of the induction coil (avoiding the use of conductive materials and requiring high temperature resistance). Ceramics are non-metallic materials and will not be heated by the induction coil. In addition, the ceramic crucible is resistant to high temperatures and can withstand the heat radiated from the crucible. In the existing melting sample machine solution, the crucible can be fixed and the melting sample can be completed. However, when taking and placing the crucible, the operator needs to rely on the feeling to turn the snap connection to align with the notch of the ear piece before the crucible can be removed, which makes the crucible inconvenient to take and place.
