Problems solved by technology
[0004] Most of the existing sulfur measuring instruments use an automatic sample feeding device with a chain and a chain plate to send samples. Through the research on the existing technology, the applicant found that: the existing sulfur measuring instruments have the following problems: 1. When sending samples, The chain with chain plate is composed of at least two chains and multiple chain plates. There are many parts and it is difficult to install and maintain.
2. Due to the high temperature at the furnace mouth and the chain itself, the chain is prone to deformation and elongation after working for a long time, resulting in low positioning accuracy during transmission and prone to errors, thus affecting the experimental results
3. The combustion tube of the high-temperature furnace is circular, and the bracket for conveying the crucible is a flat plate. When a large number of crucibles are fed into or pulled out of the combustion tube from the bracket, it is easy to deflect the crucible, causing the crucible to be stuck in the furnace mouth, affecting Analysis speed of sulfur meter

Description
technical field [0001] This application relates to the field of coal quality analysis instruments, in particular to a sulfur measuring instrument with automatic sample sending function. Background technique [0002] In the series of coal quality analysis instruments, in order to determine the sulfur content of combustibles and others, in the existing technology, in order to accurately and quickly measure the content of each element in the coal sample, it is generally used to put the coal sample in the corresponding element Combustion in the high-temperature furnace of the analytical instrument, the content of each element in the coal is determined by measuring the content of elements in the gas burned out, because the rapid combustion of coal samples requires a high temperature (above 1000 degrees) and in order to reduce the furnace body For heat loss, the diameter of the combustion tube is often relatively small. Therefore, in various existing elemental analysis instruments...
