Abstract

The invention relates to an organic solid purification device based on a zone melting principle. The device comprises a base (1), a lead screw (2), a sliding block (3), a stepping motor (4), a motion controller, a metal contact (5), a heating ring device (6), a test tube (7), a test tube fixing frame (8), a vacuuming device, two proximity switches (9), and at least one guide rail (10). Based on the technical scheme disclosed by the invention, the hardware modules are connected, so that the organic solid purification device based on the zone melting principle is formed; based on a zone melting technology, the organic solid purification device is used for solving the problems that the structure is complex, the size is large, the reliability is low, the efficiency is low, and the automation level is low in the prior art; an advanced automation control technology is adopted, so that the device has the advantages that the automation level is relatively high, the reliability is high and the operation is easy, and can be used for completing the purification of a small quantity of organic solids and effectively improving the accuracy of experimental results of purification of organic matter in labs.

Description

technical field [0001] The invention relates to an organic solid purification device based on the principle of zone smelting, belonging to the technical field of purification operation. Background technique [0002] Regional smelting is one of the important new chemical technologies. This technology appeared earlier in developed countries such as the United States, the Netherlands, the United Kingdom, and Japan. Or a way to change its distribution. It was first proposed by W.G.Pfann in 1952, and it was initially applied to the production of high-purity germanium, and then became a research hotspot, and is widely used in the preparation of high-purity materials. As early as the 1950s and 1960s, regional smelting technology made breakthroughs in relevant theories, obtained relatively mature technical data, and developed some early prototypes of regional smelting and purifying instruments for commercial applications, and then some instrument products came out one after another...

AI Technical Summary

Problems solved by technology

At present, it also involves the research of instruments and related technologies such as ultra-purification of silicon and germanium, high-vacuum optical fiber purification device for regional melting, multi-melting zone generation device for metal hydrogen, and single crystal growth, but it is still in the experimental stage in many aspects. and the stages of exploration

Due to the complex structure, bulky size, low reliability, low efficiency and low automation level of many developed regional melting purification devices, these will have a negative impact on the product research and promotion of regional melting and purification technology.
