Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tar analysis equipment, and particularly relates to a tar moisture measuring device. Background Art
[0002] During tar loading, the moisture content of tar is determined by squeezing the sample between two pieces of glass and then observing the sample. This primitive method has many drawbacks: Tar measurements are taken frequently during loading, averaging once per minute. The two separate pieces of glass are inconvenient to carry, and the sample requires both hands to squeeze simultaneously. This doesn't ensure uniform force applied to the sample, which can easily lead to deviations in the test data. In cold weather, the primitive method requires constant demisting of the glass pieces to ensure accurate observation. In poor lighting conditions, loaders must use additional light sources to supplement the illumination of the glass pieces. Consequently, primitive measurement tools are inefficient during high-frequency operations, making them prone to confusion and measurement deviations under adverse conditions. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1-3As shown, a tar moisture measuring device includes an upper pressing device, a lower pressing device and a connecting shaft 5;
[0023] The upper pressing device includes an upper pressing plate 1 and an upper pressing cover 3. A circular upper pressing cover mounting groove 2 is opened in the middle of the upper pressing plate 1. The upper pressing cover 3 is horizontally arranged in the upper pressing cover mounting groove 2 through an upper pressing cover fixing shaft 4. The upper pressing cover 3 rotates around the upper pressing cover fixing shaft 4. An upper pressing mirror is provided on the bottom surface of the upper pressing cover 3. When squeezing the tar drop sample, the angle difference between the upper and lower pressing mirrors is eliminated, so that the tar drop sample is subjected to uniform force, thereby ensuring the accuracy of the measured value.
[0024] The pressing device includes a lower pressing plate 6, a lower pressing mirror 9, an electric heating wire 10, a background sheet 11 and a plurality of LED light groups 12. One end of the lower pressing plate 6 is hinged to one end of the upper pressing plate 1 through a connecting shaft 5. The upper pressing plate 1 and the lower pressing plate 6 are respectively installed with corresponding buckles 8 at one end away from the connecting shaft 5, which are used to maintain the compressed state of the tar drop sample for a long time. A lower pressing mirror mounting groove is opened in the middle of the top surface of the lower pressing plate 6. The distance from the lower pressing mirror mounting groove to the connecting shaft 5 is equal to the distance from the upper pressure cover mounting groove 2 to the connecting shaft 5. The lower pressing plate 6 A mounting cavity 7 is provided on one side wall, and the mounting cavity 7 is communicated with the downward pressure mirror mounting groove to facilitate the installation and replacement of the battery. The downward pressure mirror 9 is arranged in the downward pressure mirror mounting groove. The heating wire 10 is arranged in a circle along the bottom edge of the downward pressure mirror 9 to provide heat energy for the downward pressure mirror 9, eliminate the freezing of the tar drop sample and the atomization of the surface of the downward pressure mirror 9. The background sheet 11 is made of polycarbonate and is arranged on the bottom surface of the heating wire 10. The plurality of LED light groups 12 are evenly arranged on the bottom surface of the background sheet 11 to provide fill light, so that the tar drop sample is easy to observe;
[0025] A battery is provided at the bottom of the lower pressure mirror mounting groove, and the battery is electrically connected to the heating wire 10 and the LED light group 12 respectively. An LED light group switch 13 and a heating wire switch 14 are provided on the side wall of the lower pressure plate 6. The LED light group switch 13 is electrically connected to the LED light group 12, and the heating wire switch 14 is electrically connected to the heating wire 10.
[0026] The background sheet 11 can also be made of polystyrene or ABS.
[0027] The working process of this utility model:
[0028] When in use, open the buckle 8, lift the upper pressing plate 1, use a dropper to drop the tar sample on the center of the lower pressing mirror 9, then press the upper pressing plate 1 downward, and when the upper pressing cover 3 touches the lower pressing mirror 9, rotate around the upper pressing cover fixed axis 4. When the upper pressing plate 1 and the lower pressing plate 6 are completely pressed together, lock the buckle 8. At this time, the tar sample is tightly and evenly squeezed between the upper pressing mirror and the lower pressing mirror 9, and the moisture therein is squeezed out. The staff observes the moisture. Due to the uniform extrusion force, the deviation caused by the detection can be minimized.
[0029] When encountering a cold environment, turn on the heating wire switch 14. At this time, the heating wire 10 provides heat energy for the downward pressure mirror 9 to eliminate the freezing of the tar drop sample and the surface atomization of the downward pressure mirror 9. When encountering poor light conditions, turn on the LED light group switch 13. At this time, the LED light group 12 is used to fill in the light through the background sheet 11. Since the background sheet 11 is made of translucent material, the light emitted by the LED light group 12 becomes gentle and not dazzling when it is passed through the background sheet 11 for fill in the light.
