Abstract

The invention discloses a neutralization sulphur meter with a function of automatic drying and belongs to the field of coal sulfur content automatic measuring equipment. The neutralization sulphur meter comprises a combustion furnace and a drying device fixed to a base plate, a combustion tube, a nickel-cadmium push rod, an oxygen bottle and a gas collection bottle with a sodium hydroxide solution, and a sucking pump connected to the gas collection bottle through a gas-guide tube. The oxygen bottle and the gas collection bottle are respectively connected to two ends of the combustion tube through gas-guide tubes. The drying device comprises a drying tank of which the inner wall is provided with a resistance wire, an upper end cover, a lower end cover, a positioning plate, a rotation disc arranged in the drying tank, a rotation shaft of which the upper end is provided with the rotation disc, a temperature sensor and a blower. The neutralization sulphur meter has a simple and compact structure and a high automation degree, can fast dry a sample and has an automatic drying function.

Description

technical field [0001] The invention mainly relates to the field of automatic measurement equipment for sulfur content in coal, in particular to a neutralization method sulfur measuring instrument with automatic drying function. Background technique [0002] The content of sulfur element is one of the important indicators for evaluating coal quality, which needs to be determined quickly and accurately. As one of the rapid determination methods of total sulfur in coal, the high-temperature combustion neutralization method can obtain the test results in a short time. At present, a few countries have listed this method as a national standard. Most of the neutralization methods in the prior art are manually operated, and a very important step is to dry the experimental sample. Manual operation makes the operator labor-intensive, high risk, and human error. Contents of the invention [0003] The technical problem to be solved in the present invention is: aiming at the technic...
