When the graphite electrode horizontal moving device is used, a graphite electrode is arranged on the small U-shaped electrode support points of the conducting wire connecting beam; when the gear linkage rod is clockwise or counterclockwise rotated, the adjusting gear can drive the graphite electrode to move forwards or backwards along the conducting wire connecting beam. When the graphite electrode horizontal moving device is used in an emission spectrum chromatograph, the graphite electrode horizontal moving device has the advantages that the safety coefficient is high, the conductivity is good, the high temperature-resistant property is realized, the non-slippage, non-offset and non-swinging effects of graphite electrode moving are realized, and the like.

Description

technical field [0001] The invention relates to a device for horizontally moving a graphite electrode that can be used on an emission spectrograph, that is, a graphite electrode horizontal mover, and belongs to the technical field of spectroscopy experimental devices. Background technique [0002] Common electrode horizontal moving devices include spring type, double bracket type and single bracket type. These electrode moving devices all have deficiencies in varying degrees, as follows: The spring-type electrode horizontal moving device uses the tension generated by the elasticity of the spring to compress the graphite electrode and the adjusting gear. When the adjusting gear is turned clockwise or counterclockwise, the graphite electrode You can move it back and forth as needed. Since the graphite electrode is in a high temperature state during operation, the heat will be transferred to the electrode horizontal moving device, and the spring will lose its elasticity after ...

AI Technical Summary

Problems solved by technology

Because when the adjusting gear rotates clockwise or counterclockwise, the pressure of the adjusting gear acting on the graphite electrode is different, and the two small holes installed under the adjusting gear housing will block the double brackets, resulting in the unsmooth movement of the adjusting gear up and down, thus If the adjusting gear cannot press the graphite electrode tightly, there will be slippage between the graphite electrode and the adjusting gear. If the diameter of the two small holes is increased, the adjusting gear will shake from side to side, causing the graphite electrode to also shake from side to side, which will eventually affect the spectrum. Measuring quality of the instrument

The working principle of the single bracket type electrode horizontal moving device is the same as that of the double bracket electrode horizontal moving device. The up and down movement between the two small holes under the gear and the double brackets is not smooth, but since there is only one bracket, the adjustment gear swings from side to side in a large range, which affects the normal operation of the spectrograph
