Description

Technical Field

[0001] This invention relates to a detection device, specifically used in detecting the wear degree of a fineness probe for air-powder particles. Background Technology

[0002] The air-powder probe is a key component of the air-powder fineness analyzer. Its working principle involves inserting the probe end into the air-powder pipeline. The impact of solid particles generates transient elastic waves, which are transmitted to an acoustic emission sensor. After signal processing and calculation, this data becomes crucial information for solid particle size detection. Experiments have shown that the insertion depth of the probe inside the pipeline is a significant factor affecting the overall system performance. Due to air-powder erosion, the portion of the probe inside the pipeline continuously wears down. Therefore, a device is needed to detect the wear degree of the probe within the sealed space inside the air-powder pipeline and to adjust the probe insertion depth based on the wear condition. Utility Model Content

[0003] This novel design provides a particle fineness probe detection device that can automatically detect the wear degree of the probe and automatically adjust the probe insertion depth based on the detection results. It features a simple structure, low manufacturing cost, convenient installation and maintenance, and easy operation.

[0004] This invention includes a powder-air duct, a photoelectric switch, and a probe. The probe is inserted into the powder-air duct, and the powder-air duct has two symmetrical through holes in the direction perpendicular to the probe. The end of the probe is located on the line connecting the two symmetrical through holes, and two corresponding photoelectric switches are installed outside the two symmetrical through holes.

[0005] In one example, a probe mounting bracket is fixed to the outside of the pipe for mounting the probe.

[0006] In one example, a viewing window is installed inside the through-hole.

[0007] In one example, the detection device further includes an insertion depth adjustment mechanism connected to the probe rod, which automatically adjusts the insertion depth of the probe rod according to the signal from the through-beam switch. Attached Figure Description

[0008] Figure 1 Overall structural diagram. Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0010] See Figure 1This novel embodiment provides a powder fineness detection device, comprising: a powder pipe 1, a through-beam switch 2, and a probe 5. The probe 5 is inserted into the powder pipe 1, and the powder pipe 1 has two symmetrical through holes perpendicular to the probe 5. The end of the probe 5 is located on the line connecting the two symmetrical through holes. Two corresponding through-beam switches 2 are installed outside the two symmetrical through holes, and the two corresponding through-beam switches 2 can form an optical path through the transmission and reception of light. Since the end of the probe is located on the line connecting the two symmetrical through holes, the end can block the passage of light, and the passage of light reflects the insertion depth of the probe end.

[0011] In one example, a probe holder 4 is fixed to the outside of the pipe for mounting the probe 5. The specific form of the probe holder is not limited; any method that can secure the probe is acceptable.

[0012] In one example, a viewing window 3 is installed inside the through-hole, allowing the aforementioned light to pass through. Alternatively, the viewing window can be omitted, and the through-hole can be directly installed.

[0013] In one example, the detection device further includes an insertion depth adjustment mechanism 6, which is connected to the probe 5. The insertion depth adjustment mechanism automatically adjusts the insertion depth of the probe according to the signal from the through-beam switch.

[0014] Specifically, due to the obstruction at the probe end, the light paths of the two-way inter-beam switches cannot pass through. The probe end is eroded by wind and dust, causing wear to gradually increase. Consequently, the light throughput of the two-way inter-beam switches increases. When the first set value is reached, the inter-beam switch sends a first trigger signal to the insertion depth adjustment mechanism. Upon receiving the signal, the insertion depth adjustment mechanism begins to operate, causing the probe to gradually increase its insertion depth. As the insertion depth increases, the light throughput of the two-way inter-beam switches decreases. When the second set value is reached, the inter-beam switch sends a second trigger signal, and the insertion depth adjustment mechanism stops operating, completing the automatic insertion depth adjustment.

[0015] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
