Sulphur analysis instrument with sampling positioning-detection and protection mechanism

Abstract

The invention discloses a sulfur determination instrument with a sample delivery positioning detection and protection mechanism, which includes a furnace body fixed on the bottom plate, a control mechanism, a sulfur amount sensing device, a drying device, a flow sensor and a sulfur sensor connected in sequence through pipelines. pump, the furnace body is equipped with a combustion tube, the sulfur sensor is connected to the tail end of the combustion tube through a pipeline, the inlet end of the furnace body is provided with a sample delivery nozzle, and the sample delivery nozzle is connected to the sample delivery device, and the sample delivery device There is a sample delivery positioning detection and protection mechanism on the top. The invention has simple and compact structure, low cost, high measurement accuracy, can effectively detect the reliability of the movement of the sample rod, and detect whether the sample boat is correctly sent into the constant temperature zone of the furnace body, thereby improving the error tolerance and error correction of the instrument sex.

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 sample delivery positioning detection and protection mechanism. 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 generate harmful SO after combustion. 2 and SO 3 Gas and fly ash are discharged into the atmosphere along with flue gas, causing air and environmental pollution. Therefore, the detection of sulfur content in coal samples is a very important task for coal production, sales, use, and environmental protection departments. 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 various measuring equipment, ...

Problems solved by technology

When the sample boat is placed on the sample boat platform by manual or automatic sample delivery device, the sample boat is not aligned due to some factors, it is tilted or rolled over, and the sample boat is easy to cause the sample boat or even the The sample boat platform is stuck by the sample delivery nozzle and cannot move forward. At this time, a necessary detection and protection measure is often lacking, and the control mechanism cannot detect the fault in time and give an alarm.

However, the sample boat, sample boat platform, and combustion tube are mostly made of fragile materials, such as ceramics and quartz. When the sample feeding motor is forced to move forward, the sample boat and sample boat platform are often damaged and the sample injection The rod is bent, even the motor is burned out, and the combustion tube is broken

The instrument is no longer used, which directly affects the production and testing work of the user unit, and the consequences are immeasurable

In addition, when there are residues in the combustion tube that have not been cleaned up in time, the experiment will also bring about the above problems
