Automatic measuring device for calcium carbide gas evolution

Abstract

The invention relates to the technical field of automatic sampling, sample preparation and assay in the calcium carbide industry, and provides an automatic measuring device for calcium carbide gas evolution. The device comprises an equipment box body and an equipment base assembly. The equipment box body is mounted above the equipment base assembly. the equipment base assembly is provided with anautomatic sample adding chamber, a gas generator, a gas-liquid separator, a gas measuring bell jar assembly, a water adding pipeline assembly, an exhaust pipeline assembly, a slag discharging drawer assembly, an overflow underwater pressing device and a water discharging groove. A sample adding hole is formed in the equipment box body. The gas-liquid separator is communicated with the gas measuring bell jar assembly through an exhaust pipeline assembly. The gas generator is communicated with the deslagging drawer assembly. A slag discharging pneumatic ball valve is arranged between the gas generator and the slag discharging drawer assembly, the water discharging groove is formed below the slag discharging drawer assembly, the overflow underwater pressing device is arranged above the slag discharging drawer assembly, and the problems that an existing calcium carbide gas evolution amount test is greatly influenced by human factors, the test efficiency is low, and the automation degree islow are solved.

Description

Technical field [0001] The invention relates to the technical fields of automated sampling, sample preparation and testing in the calcium carbide industry, and specifically relates to an automatic measurement device for gas generation of calcium carbide. Background technique [0002] Calcium carbide, the chemical name is calcium carbide, its main uses are: [0003] (1) Acetylene generated by the reaction of calcium carbide and water can synthesize many organic compounds, such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used for welding and cutting of metals. [0004] (2) When heating powdered calcium carbide and nitrogen, the reaction produces calcium cyanamide, that is, lime nitrogen. The cyanide melt produced by the reaction of heating lime nitrogen and salt is used in gold mining and non-ferrous metal industries. [0005] (3) Calcium carbide itself can be used as a desulfurizer in the steel industry. ...

AI Technical Summary

Problems solved by technology

At present, the automation of calcium carbide sampling, sample preparation, and assay is not high, and there are still many links that need to be continuously improved.

Among them, the determination of calcium carbide gas generation is still a manual operation, resulting in the test results will be affected by human factors, and the calcium carbide test work is relatively heavy and cumbersome, and test failures occur from time to time due to improper operation, which greatly reduces the test efficiency. It also takes a lot of energy to transcribe, organize and analyze, and the traceability of the data is poor in the later stage. It is urgent to develop an automatic measurement device for calcium carbide gas production to solve the above problems currently encountered
