Automatic operation method for mixing, sample melting and soot blowing of fire assays

Abstract

The invention relates to an automatic operation method for mixing, sample melting and soot blowing of fire assays, and belongs to the field of fire assays. The method comprises the steps of automaticmixing, automatic sample melting, automatic soot blowing and the like, and a sample melting furnace, a soot blowing furnace and a mechanical arm system are arranged in a high-temperature area; a mixing station and a silver nitrate and covering agent adding station are arranged in a normal temperature area; and samples or objects are conveyed between the high-temperature area and the normal-temperature area through a conveying line and a sliding table, manual one-by-one sample operation is changed into mechanical batch operation, and operation of mixing, sample melting and soot blowing of 40 samples can be conducted at the same time in each batch. The detection efficiency and the detection data stability are greatly improved, the manual operation error is reduced, the labor environment is improved, the occupational safety risk is reduced, the physical expenditure of inspectors is reduced, and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to the field of fire assay gold, in particular to an automatic operation method for fire assay gold mixing, melting samples and ash blowing. Background technique [0002] The fire test gold analysis method is the main detection method for gold and silver analysis and trade arbitration in the gold industry at home and abroad. The laboratory’s daily inspection process for ore samples is relatively fixed, and inspectors still repeat manual sample-by-sample inspection operations every day, including manual sample-by-sample batching, mixing, furnace loading, furnace extraction, ash blowing, gold separation, and weighing. During the testing process, testing personnel need to manually stir and mix each batch of reagents one by one with a stirring ruler after each batching. The manual stirring speed is slow, the efficiency is low, it is easy to cause sample overflow, and it is easy to raise lead oxide and other substances. Dust of non-me...

Problems solved by technology

[0003] The invention provides an automatic operation method for fire testing gold mixing, melting samples, and ash blowing to solve the existing manual stirring speed, low efficiency, easy to cause sample overflow, and easy to raise lead oxide and other Dust of non-metallic harmful substances; toxic fumes containing lead oxide and other compounds will be released during the melting process and ash blowing process, which is easy to inhale into the inspector's body, not only the detection efficiency is slow, the physical expenditure is large, and the health of the inspector is affected question
