Automatic release device for foam adsorption of gold

Abstract

An automatic release device for foam adsorption of gold in the present invention at least includes: a test tube group for accommodating the adsorption gold foam; a water bath for heating and adsorbing the gold foam, the water bath is provided with an electric heating tube and a temperature sensor for real-time detection of water temperature, Feedback the water temperature to the automatic controller; arrange it under the water bath, extrude the extruding body that absorbs the gold foam, and the extruding body is connected with the tray through an electromagnet; the main box includes an automatic controller; The driver that controls the working state of the electric heater, the actuator, and the suction cup according to the instructions of the controller; the actuator that receives the start instruction of the driver and drives the suction cup to reciprocate up and down to complete the release process. The invention has high degree of automation and high efficiency, and the release extrusion process is carried out at a constant temperature. The release is complete, the consistency is good, the analysis quality is stable, and there is no crystallization, which completely avoids the clogging of the straw of the analysis instrument due to the crystallization.

Description

technical field [0001] The invention relates to an automatic release device for foam adsorption gold. Background technique [0002] At present, foam adsorption is generally used in the determination of gold content in ore samples in mineral resource exploration, and instrumental analysis or chemical analysis is performed after thiourea is released. The thiourea release process is as follows: put the gold-adsorbed foam in a test tube containing thiourea solution, then place it in a water bath to keep the temperature constant for a certain period of time, then squeeze the gold quickly with a glass rod to release the gold from the foam, and then release the gold from the foam. The completed sample solution is subjected to instrumental analysis or chemical analysis. This method generally adopts manual operation at present, and there are following problems. 1. Low work efficiency; high labor intensity, especially when the sample batch is large. 2. Since the extrusion process c...

AI Technical Summary

Problems solved by technology

1. Low work efficiency; high labor intensity, especially when the sample batch is large

2. Since the extrusion process cannot be carried out directly in the water bath, it can only be taken out of the water bath and then extruded after cooling down. However, during batch operation, some samples whose temperature is too low will cause crystallization, and the instrument will be blocked during instrument analysis. the pipette

Manual extrusion will also cause some foam fragmentation particles to enter the sample liquid and block the pipette of the instrument

Due to the inconsistent temperature of the release solution in different test tubes during manual extrusion, the release efficiency is inconsistent, which in turn affects the accuracy and precision of the analysis results.
