Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, and in particular to a needle device for a gel layer measuring instrument. Background Technology
[0002] Currently, the detection of gelatinous layers generally relies on manual handheld probes, which demands extremely high operator skills and proficiency. Automated instrument testing suffers from several problems: the probe tip may fail to enter the lower probe port during descent, or the gelatinous material may solidify and block the port, causing breakage and resulting in detection failure; the probe may tilt and fail to insert into the effective detection area, leading to large deviations in the results; and the probe tip may adsorb a large amount of gelatinous material, causing significant interference. These issues result in low detection accuracy, long analysis cycles, and severely impact production operations. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a probe device for a gel layer measuring instrument to ensure smooth probe operation.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The tube body is fixedly connected to the bracket.
[0007] The adhesive removal block is cone-shaped, with a larger inner side and a smaller outer side.
[0008] The aforementioned pushing device is a pneumatic cylinder or a hydraulic cylinder.
[0009] The inner tube is a ceramic tube or a quartz tube.
[0010] The bottom of the tube is also provided with a funnel-shaped connector, which is fixedly connected to or detachably connected to the tube.
[0011] The inner diameter of the tube opening at the bottom of the funnel-shaped connector is 2-3 mm.
[0012] Compared with existing technologies, the beneficial effects of this utility model are:
[0013] This invention guides the probe to run vertically and removes any adhesive residue adhering to the probe, reducing the labor intensity of manual cleaning. It ensures smooth probe operation, effectively reducing the frequency of experimental termination due to probe breakage, shortening the analysis cycle, improving equipment detection performance, and increasing probe lifespan.

[0020] like Figures 1-3A probe device for a gel layer measuring instrument is disclosed. The measuring instrument includes a bracket 11 and a coal cup 12. A paper tube 13 is disposed inside the coal cup 12. The probe device is vertically aligned with the paper tube 13. The probe device includes a tube body 1, which includes an inner tube 2 and an outer tube 3 nested together. The top ends of the inner tube 2 and the outer tube 3 are connected to a top cover 4. A probe hole 5 is provided at the center of the top cover 4. A heating resistance wire 6 is wound on the outer wall of the inner tube 2. Gel removal blocks 7 are symmetrically arranged inside the bottom of the tube body 1. The gel removal blocks 7 are connected to a push rod 8. The push rod 8 extends out of the tube body 1 and is connected to a pushing device 9. The gel removal blocks 7 are driven by the pushing device 9 to move in opposite directions.
[0021] The tube 1 is fixedly connected to the bracket.
[0022] The adhesive removal block 7 is cone-shaped, with a larger inner side and a smaller outer side.
[0023] The pushing device 9 is a pneumatic cylinder or a hydraulic cylinder. The pushing device 9 is fixedly connected to the bracket 11.
[0024] The inner tube 2 is a ceramic tube or a quartz tube.
[0025] The bottom of the tube body 1 is also provided with a funnel-shaped connector 10, which is fixedly connected to or detachably connected to the tube body 1.
[0026] The inner diameter of the tube opening at the bottom of the funnel-shaped connector 10 is 2-3 mm.
[0027] Work process:
[0028] After the coal sample in the coal cup 12 reaches the detection temperature, the probe 14 begins to move downwards via the probe guide device, probing into the paper tube 13 for detection. After detection, the sticky substance adhering to the probe 14 rises, and the pushing device 9 pushes the two de-adhesive blocks 7 to move towards each other. After the heating resistance wire 6 is energized, it heats the inner cavity of the inner tube 2, softening the sticky substance. The de-adhesive blocks 7 close, and as the probe 14 moves upwards, the sticky substance is removed by the de-adhesive blocks 7. This prevents the sticky substance adhering to the probe 14 from preventing it from working properly.
