Description

Technical Field

[0001] The utility model belongs to the technical field of melting sample machines, and particularly relates to a crucible swing bracket for a melting sample machine. Background Technique

[0002] Melting sample machines are mainly used for sample preparation in AAS, ICP, and X-ray fluorescence analysis. They have the advantages of simple operation, stable performance, and safe and reliable use, and are widely used in fields such as cement, ore sand, lime, and kiln bricks. When preparing samples for X-ray fluorescence analysis, the tablet pressing method and the glass melting method are mainly used. For the X-ray fluorescence analysis of certain substances, only the glass melting method can eliminate the mineral effect and particle size effect by melting the substance into a vitreous body. Compared with the tablet pressing method, the glass melting method has the advantages of higher precision and more accurate analysis results. The glass melting method uses a melting sample machine as the heating equipment. When the melting sample machine is in use, the sample needs to be placed in a crucible, and then the entire crucible is sent into the melting sample machine for heating. After heating is completed, the crucible needs to be swung to a suitable angle by a crucible swing system so that the sample in the crucible flows into the forming dish. After the sample cools in the forming dish, the sample to be tested is obtained.

[0003] Currently, the patent application number of the product developed by our company is 202222600658.9, and the name is a rotary swing bracket for a melting sample machine crucible. The main technical problems are as follows: 1. The annular edge around the upper part of the crucible is relatively narrow. When swinging the crucible to pour the molten sample into the forming dish, the limiting strip cannot limit the crucible well, resulting in the crucible falling during the sample pouring process, causing the failure of sample preparation and there is also a safety hazard; 2. Both sides of the strip-shaped groove are arc-shaped, and the middle is rectangular. The purpose is to first place the crucible in the middle rectangular part when placing the crucible, and then push the crucible so that the retaining edge of the crucible is stuck in the limiting groove. In order to be able to place two crucibles at the same time, the length of the middle rectangular part of the strip-shaped groove has to be greater than the width of the crucible itself, which results in a small number of crucibles that can be placed on the crucible placement plate body, leading to low efficiency in preparing samples to be tested. Based on the above defects existing in the prior art, a crucible swing bracket for a melting sample machine has been developed, which can well solve the above problems existing in the prior art. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a crucible swing bracket for a melting sample machine, which has a simple structure and is convenient to use. By opening a limiting groove corresponding to the upper end of the crucible placement groove at the bottom of the limiting strip, it can hold the handle of the crucible with a handle during the process of pouring the sample after melting is completed, avoiding the crucible from falling.
