Description

Technical Field

[0001] This utility model relates to the field of coal total sulfur determination technology, and in particular to an automatic tungsten trioxide addition device for laboratory use. Background Technology

[0002] Sulfur is one of the harmful elements in coal, and its content directly affects coal quality. Measuring the total sulfur content in coal allows for an accurate assessment of its cleanliness, guiding its rational utilization and preventing the use of high-sulfur coal in sensitive industries. This protects the environment and equipment, ensures that coal use meets environmental protection requirements, and avoids environmental problems caused by excessive sulfur emissions. During coal production, regular measurement of the total sulfur content also allows for monitoring production quality, timely adjustments to production processes, and ensuring product quality stability.

[0003] In the experiment for determining total sulfur in coal, the decomposition temperature of sulfate sulfur is 1300℃. To lower this temperature, tungsten trioxide is manually added to the coal sample surface as a catalyst using a weighing spoon. After adding tungsten trioxide, the sulfate sulfur can decompose at (1150±10)℃, thus accurately determining the total sulfur content in the coal. However, this manual addition method is not only inefficient but also makes it difficult to ensure uniform catalyst coverage, affecting the accuracy of the test results. Therefore, this invention proposes an automatic tungsten trioxide addition device to address the shortcomings of existing technologies. Utility Model Content

The X-axis moving module 3 has a base 1 on one side with a stand 9 on top. A support plate 5 is detachably installed on one side of the upper end of the stand 9. The automatic tungsten trioxide weighing and feeding mechanism includes a test tube 10, a metering tube 11, a flow meter 12, and a feeding tube 13.

The feeding tube 13 is connected to the metering tube 11, and the feeding tube 13 is provided with a second solenoid valve 15.

[0024] When using the automatic tungsten trioxide addition device for experiments of this utility model, multiple crucibles containing coal samples are placed sequentially in the positioning groove 8. The size of the positioning groove 8 on the sample tray 7 of this utility model is customized according to the size of the crucibles, and the two are compatible. Then, by activating the X-axis moving module 3 and the Y-axis moving module 4, corresponding movements are made so that the first crucible on the sample tray 7 is moved directly below the automatic tungsten trioxide weighing and feeding mechanism. By controlling the flow, the tungsten trioxide in the test tube 10 is fed into the metering tube 11. The flow meter 12 measures the amount of tungsten trioxide fed. Then, the first solenoid valve 14 is closed and the second solenoid valve 15 is opened so that the weighed tungsten trioxide in the metering tube 11 is fed into the feeding tube 13. Then, the material is discharged from the feeding tube 13 into the corresponding crucible containing the coal sample.

[0025] The X-axis moving module 3 includes an X-axis mounting base 301, an X-axis lead screw 302, and an X-axis moving seat 303. The X-axis lead screw 302 is rotatably mounted inside the X-axis mounting base 301, and the X-axis moving seat 303 is threadedly connected to the X-axis lead screw 302. The X-axis moving seat 303 is slidably connected to the inner wall of the X-axis mounting base 301.

By activating the first motor 304, the X-axis lead screw 302 can be rotated, and then the X-axis moving seat 303 moves within the X-axis lead screw 302 and the X-axis mounting base 301, thereby moving the entire Y-axis moving module 4 located at the top of the X-axis moving seat 303.

[0026] The Y-axis moving module 4 includes a Y-axis mounting base 401, a Y-axis lead screw 402, and a Y-axis moving seat 403.

A second motor 404 is provided on one side of the Y-axis mounting base 401, driving the Y-axis lead screw 402 to rotate. When the second motor 404 is started, it drives the Y-axis lead screw 402 to rotate, and then the Y-axis moving seat 403 moves within the Y-axis lead screw 402 and the Y-axis mounting base 401, thereby moving the entire tray fixing mechanism 6 located on top of the X-axis moving seat 303.

[0027] The tray fixing mechanism 6 includes a positioning base plate 601, positioning side plates 602, and positioning bolts 603.

The positioning side plates 602 are connected to the positioning base plate 601 by the positioning bolts 603. When fixing the sample tray 7, the sample tray 7 is placed on the top of the positioning base plate 601, then the positioning side plates 602 are placed on both sides of the sample tray 7, and then the positioning side plates 602 are locked by the positioning bolts 603, so that the positioning side plates 602 clamp the sample tray 7.

[0028] The support base 9 is symmetrically provided with adjustment slots 16. One end of the support plate 5 is detachably installed to the support base 9 at the adjustment slots 16 via fixing bolts and nuts. By setting the adjustment slots, the position of the support plate 5 can be adjusted, thereby adjusting the distance between the lower end of the feed pipe 13 and the crucible.

[0030] The positioning base plate 601 has a dovetail groove 17 at its top, and the sample tray 7 has a limiting block 18 at its bottom, which engages with the dovetail groove 17. By setting the dovetail groove 17 and the limiting block 18 to cooperate, the installation of the sample tray 7 on the top of the positioning base plate 601 has the advantages of being quick and having high positioning accuracy. The sample tray 7 can be slid into the dovetail groove 17 by the limiting block 18 at the bottom, and then the positioning side plate 602 is locked by the positioning bolt 603, so that the positioning side plate 602 clamps and secures the sample tray 7.
