Description

Rotary disc type multi-degree-of-freedom barium sulfate sulfur measuring device

Technical Field

The invention mainly relates to the field of automatic measuring equipment for the sulfur content of barium sulfate, in particular to an Eschka sulfur measuring device capable of automatically weighing barium sulfate.

Background

Sulfur is very harmful to coal coking, gasification, and combustion and needs to be measured accurately. In order to accurately and rapidly measure the sulfur content of sulfur element in coal, a sulfur determinator or a sulfur detector is generally used as a commonly used measuring device. In the prior art, a coulometry sulfur method is adopted. The coulometric sulfur method needs a pump as a power source and adopts a continuous air extraction and continuous measurement mode for measurement. Since the sulfur concentration in the gas varies with time, the sulfur content is difficult to measure accurately, and the pump life is shortened due to load imbalance. The classic Eschka sulfur measurement method is a standard method for measuring the total sulfur content in coal commonly used in various countries at present, and has the advantages of high accuracy, batch measurement and the like. The last step of measuring sulfur by the Israel method is as follows: the crucible containing the ashed filter paper and barium sulfate was taken out of the muffle furnace, slightly cooled in air, and then placed in a desiccator to be cooled to room temperature (about 25 to 30min), and the mass of barium sulfate was measured. One step in the prior art is mostly in a manual mode, and completely automatic Eschka sulfur measuring equipment is rarely used abroad.

The skilled person is constantly improving the production technology and production equipment of barium sulfate. Related technical documents in existing sulfur measuring apparatuses include patent documents [ application No.: 201510531466.9 discloses a sulfur detector with automatic weighing function, which is mainly fixed on a bottom plate and comprises an Aishi sample making device, a combustion furnace, a solution stirring device, a first filtering device, a second filtering device, a chloride ion removing device, a filter paper ashing device and a barium sulfate weighing device; the barium sulfate weighing device comprises a weighing disc arranged at the top of the rotating shaft, a weighing rod arranged on the digital balance, a bearing frame, a rotating motor, a main support, an upper support, a lower support, a lifting motor frame, a ball screw, a guide rail, a sliding block, a rolling nut and a lifting motor. The device structure is fairly simple, can alleviate barium sulfate to a certain extent and contain the big and inefficiency problem of the sulphur content test degree of difficulty, but its sulphur content that can only measure a barium sulfate container at every turn, consequently measurement of efficiency is not high, and the action process also lacks the flow nature, has consequently restricted its application range.

In conclusion, the traditional barium sulfate measuring method has the defects of low measuring efficiency, lack of flow property in the action process, insufficient consideration of details, overlarge labor intensity of workers and the like.
