Sulphur determination device with movable sample presentation platform

Abstract

The invention discloses a sulphur determination device with a movable sample presentation platform which comprises a combustion furnace fixed on a base plate, a control mechanism, and a filtering device, a sulphur content sensing device, a flow rate detector and a pump which are connected in sequence; a combustion tube is arranged in the combustion furnace; the filtering device is connected with an escape pipe of the combustion tube by a pipeline; an inlet end of the combustion furnace is provided with a sample presentation nozzle; a crucible pushing movement mechanism is arranged at one sideof the sample presentation nozzle; the inlet end of the sample presentation nozzle is provided with the moveable sample presentation platform which is used for transferring the crucible on the crucible pushing movement mechanism; one end of the moveable sample presentation platform is connected with the sample presentation nozzle and the other end is provided with a sample presentation rod movement mechanism which causes the crucible to move. The sulphur determination device with the movable sample presentation platform has simple and compact structure, higher automation degree, lower failurerate, and higher space utilization rate.

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 movable sample delivery platform. Background technique [0002] In the prior art, there are mainly two types of sulfur determination instruments, single-sample manual and multiple automatic. The single-sample manual sulfur determination instrument adopts the traditional test method, which is a horizontal furnace body, and is manually weighed and set out. Although the sample input and output and data processing are completed by computer control, but because only one sample can be placed at a time, the operator cannot leave the instrument, which reduces the work efficiency; and each time the sample is taken and set out, it is necessary to open the sample delivery nozzle that may be hot due to high temperature cover, it is very easy to be scalded. There are two kinds of vertical furnace ...

AI Technical Summary

Problems solved by technology

This way of moving often results in that when the crucible stops at the sample delivery nozzle, one side of the crucible is always connected with the push plate (block) or there is a small gap

Moreover, in the prior art, the crucible is generally pushed and placed on the crucible support plane connected with the sample delivery rod, and the crucible is sent and taken indirectly, which is not a stable structure.

When the crucible is pushed into or taken out of the furnace body by the sample feeding rod, the side of the crucible tends to scrape against the push plate, causing the crucible to shift, tilt or roll over

Tilting will move the flattened sample in the crucible, resulting in uneven thickness of the stack, so that the thick part of the sample will not be fully burned in the combustion tube, which will directly affect the accuracy of the test results and lead to measurement errors.

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. When the crucible shifts, tilts or rolls over, it may move beyond the range of the injection port. , eventually causing the situation of being stuck during the sample injection process, which will bring a series of failures and damage to the device, resulting in the instrument not working normally, directly affecting the production and testing work of the user unit, and the consequences are inestimable

In addition, for different methods of measuring sulfur, the size of the crucible varies greatly depending on the weight of the required sample. If the sample pushing method in the prior art is adopted, the space occupied by the same number of large crucibles in each batch is very large. Larger ones often lead to bulky instruments and increased costs; otherwise, the number of crucibles in each batch can only be reduced to achieve the purpose of reducing the volume
