Sulphur determination device with platform for stabilizing feeding sample

Abstract

The invention discloses a sulfur device with a feeding stable platform, comprising a furnace fixed on a bottom plate, a control device, and a sulfur flux sensor, a drier, and a flux sensor connected in turn via pipes, wherein the furnace is mounted with a burning tube, the sulfur sensor via a pipe is connected with the tail of the burning tube, the inlet of the furnace is arranged with a feeding nozzle and a sample support connected with a feeding device, the feeding device comprises a feeding rod and a drive device, the connected end of the feeding rod with the sample support is arranged with a positioning platform, and the positioning platform is arranged with a positioning pin engaged with the positioning hole. The invention has compact structure, low cost, and improved feeding reliability, with a sample feeding stable platform.

Description

technical field [0001] The invention mainly relates to the field of measuring equipment for sulfur content in combustible substances, in particular to a sulfur determination instrument with a stable platform for sample injection. Background technique [0002] Sulfur is the most important harmful component in coal samples. It mainly exists in coal in the form of elemental sulfur, sulfide, and sulfate. The sulfide contained in coal will produce SO after combustion. 2 and SO 3 Harmful substances such as gas and fly ash, and these substances will be discharged into the atmosphere with the flue gas, causing air and environmental pollution. Therefore, the detection of sulfur content in coal samples is a must for coal production, sales, use and environmental protection departments. A very important job. In the prior art, in order to accurately and quickly measure the sulfur content in combustible substances, a sulfur meter is generally used as a common measuring device. In vario...

Problems solved by technology

When the manual or automatic sample delivery device puts the sample boat on the sample boat support, it will often touch the sample boat support. Because of the small frictional resistance of the bottom arc and the linear contact between the bottom platform and the sample delivery rod, it is impossible to It plays the role of stabilizing the sample boat support, so it is easy to cause the deviation of the sample boat support, causing the sample boat placed on the sample boat support to tilt or rollover; in addition, the unstable or vibration during the sample delivery process makes the The deviation of the sample boat support will also cause the sample boat to tilt or rollover

Tilting will move the samples that have been flattened in the sample boat, resulting in uneven accumulation thickness, so that the samples in the thicker part will not burn sufficiently in the combustion tube, which will directly affect the accuracy of the test results and lead to measurement errors. produce

The rollover will invalidate the sample

What's more serious is that in order to keep the temperature in the furnace constant and reduce heat loss, the injection port of the combustion tube is often relatively small, and the two sides of the sample boat support with a boat platform have no positions, and the position of the sample boat when it tilts or rolls over Move, it may exceed the scope of the injection port, and eventually cause the situation of being stuck during the sampling process, and the sample boat, sample boat support and combustion tube are mostly made of fragile materials, such as "ceramic, quartz", etc. In this way, the sample boat and the sample boat holder will be damaged, the sample rod will be bent, and even the motor will be burned out, and the combustion tube will be broken.

As a result, the instrument cannot work normally, directly affecting the production and testing work of the user unit, and the consequences are immeasurable
