An efficient and intelligent automatic unfolding device and its application method

Abstract

The invention relates to an efficient intelligent automatic unfolding device which comprises a cylinder body, a cylinder cover, a nylon rope, two pulleys, a glass basket and an intelligent mechanical circuit control system, wherein the intelligent mechanical circuit control system is arranged on the outer wall of the cylinder body; the cylinder body and the glass basket are uncovered hollow cuboids; the glass basket is arranged in the cylinder body, a plurality of triangular holes are formed in a group of opposite side surfaces of the glass basket, and round holes are formed in four top corners of the glass basket; the two pulleys are respectively arranged on two side surfaces of the cylinder body, and two holes are formed in the cylinder body in a position which is parallel to the positions of the pulleys; the nylon rope is used for connecting the glass basket with the pulleys in both sides of the cylinder body through the round holes, and the nylon rope which bypasses the pulleys passes through the holes and then is connected with the intelligent mechanical circuit control system; the cylinder cover covers the cylinder body. The efficient intelligent automatic unfolding device has the advantages of time saving and labor saving, and intellectualization and the automation of a thin-layer chromatography device are realized.

Description

technical field [0001] The invention relates to an automatic deployment device, in particular to an efficient and intelligent automatic deployment device and a usage method thereof. Background technique [0002] Thin-layer chromatography, also known as thin-plate chromatography, is a kind of chromatography. It is a very important experimental technique for rapid separation and qualitative analysis of a small amount of substances. It belongs to solid-liquid adsorption chromatography. It combines the advantages of column chromatography and paper chromatography, and is suitable for the separation of small amounts of samples (several to tens of micrograms). Thin-layer chromatography can be divided into adsorption thin-layer chromatography (using silica gel, alumina, etc. as adsorbents), distribution thin-layer chromatography (using diatomaceous earth and cellulose, etc. as adsorbents) and ion-exchange thin-layer chromatography. [0003] The basic principle of thin-layer chromat...

AI Technical Summary

Problems solved by technology

[0005] To sum up, thin-plate chromatography plays a pivotal role in chemistry and many other fields. However, the expansion devices currently used in thin-plate chromatography are composed of two parts: a glass cylinder and a cylinder cover. Cylinder, the cylinder body is a cuboid without a cover, the bottom is a flat bottom or double tanks, and a series of steps for chromatography are manually operated, and there is no intelligent automatic deployment device

The existing developing device has the following disadvantages: (1) According to the size of the thin-layer plate, its unfolding time ranges from 10 to 30 minutes. When carrying out thin-layer spreading, the experimenter needs to pay attention to the thin-layer plate all the time, in case the developing agent Crossing the front is time-consuming and labor-intensive; (2) When the developer reaches the front, it cannot automatically stop the development. If it is not taken out in time, it will cause excessive development, and the thin-layer board can only be discarded. resources, but also consumed precious micro-experimental samples and time; (3) After the thin-layer board is unfolded, there is still the problem that the thin-layer board is not easy to take out; (4) The edge effect of the thin-layer board is also an important factor affecting the experimental effect. (5) When conducting thin-plate chromatography experiments, various types of expansion cylinders are required for convenience, which occupy too much laboratory space
