Description

Technical Field

[0001] This utility model relates to the field of coal quality analyzer technology, and more specifically to a coal quality analyzer based on infrared spectroscopy technology. Background Technology

[0002] Coal, as a vital global energy source, is widely and extensively used in numerous industrial sectors, including power generation, steel, and chemicals. Its quality characteristics directly impact key indicators such as energy efficiency, production costs, and environmental pollution levels. Therefore, accurate and rapid analysis of coal quality is crucial for optimizing coal utilization, ensuring stable industrial production, and achieving energy conservation and emission reduction.

[0003] Infrared spectroscopy is an analytical technique developed based on the differences in the absorption characteristics of different substances to infrared radiation. When infrared light irradiates a coal sample, the organic and inorganic components in the coal selectively absorb infrared light of specific wavelengths, forming a unique infrared absorption spectrum. This absorption spectrum is closely related to the chemical composition, molecular structure, and physical state of the coal. By analyzing and interpreting the infrared spectrum, information about various components in the coal can be obtained, thereby enabling qualitative and quantitative analysis of the coal quality.

[0004] As shown in the prior art published in CN210243491U, although this prior art includes a housing, a sample rotating stage on the top outer wall of the housing, a slot on the sample rotating stage for placing sample cups, a through hole on the top of the housing directly opposite the slot, a light source on one side of the housing, and a combination mirror, a sample reflected light focusing lens, a background detection optical path unit, and a Hadamard digital spectrometer module inside the housing, the diffuse reflection effect of coal in this prior art is easily affected by external light interference, which will affect the accuracy of coal quality analyzer detection. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a coal quality analyzer based on infrared spectroscopy technology. By mounting a light shield around the outside of the rotating stage, the coal material can be shielded, effectively blocking stray light from the outside and ensuring that the coal quality analyzer only receives the radiation signal from the coal itself. The sound insulation cotton inside the light shield can absorb vibration noise from the environment, reducing indirect interference of noise on the coal quality analyzer, thereby improving the detection accuracy of the coal material and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coal quality analyzer based on infrared spectroscopy technology, comprising a coal quality analyzer with infrared spectroscopy technology, wherein a rotating stage is installed on the top of the coal quality analyzer, and a container for holding coal is installed inside the rotating stage, and an auxiliary component for preventing light interference is provided on the outside of the container.

[0007] The auxiliary component includes a light shield located on top of the cup, and the light shield is fitted over the outside of the rotating platform. Sound insulation cotton is installed inside the light shield.

[0008] In a preferred embodiment, the top of the sunshade is equipped with two spaced inner rods, and a fixing cylinder is sleeved on the outside of the top of the inner rods. The fixing cylinder is provided with a spring and a positioning plate from top to bottom, and the bottom end of the positioning plate is fixed together with the top of the inner rod.

[0009] In a preferred embodiment, the diameter of the positioning plate is equal to the inner diameter of the fixed cylinder, and the diameter of the positioning plate is greater than the diameter of the inner rod.

[0010] In a preferred embodiment, both fixed cylinders are provided with fixed supports at their tops, and the top of the fixed cylinder is fixed to the bottom of the fixed support. The end of the fixed support away from the fixed cylinder is fixed to the top of the coal quality analyzer.

[0011] In a preferred embodiment, the two fixed supports are provided with the same adjusting rod at their tops. A connecting rope is installed on the side of the adjusting rod near the fixed cylinder. The end of the connecting rope away from the adjusting rod passes through the fixed support and is fixed together with the top of the positioning plate.

[0012] In a preferred embodiment, a first retaining ring and a second retaining ring are installed on the top of the fixed bracket, and the adjusting rod is located on the side of the first retaining ring away from the fixed cylinder.

[0013] In a preferred embodiment, the fixed bracket has an L-shaped cross-section, and an inclined rod for enhancing stability is installed inside the fixed bracket.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By attaching a light shield to the outside of the rotating table, the coal material can be shielded, effectively blocking stray light from the outside and ensuring that the coal quality analyzer only receives the radiation signal from the coal itself. The sound insulation cotton inside the light shield can absorb vibration noise in the environment, reducing the indirect interference of noise to the coal quality analyzer, thereby improving the detection accuracy of the coal.

[0016] 2. The spring's rebound force pushes the positioning plate and inner rod downwards, and the inner rod then pushes the light shield to fit over the coal, thus ensuring the stability of the light shield. At the same time, it can also pull the adjusting rod to move the connecting rope upwards, and the connecting rope then moves the positioning plate, inner rod, and light shield upwards, thus facilitating the height adjustment of the light shield and making it easier to pick up and put down the coal.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figure 1-5 This utility model provides a coal quality analyzer based on infrared spectroscopy technology, including a coal quality analyzer 1 with infrared spectroscopy technology. A rotating stage 2 is installed on the top of the coal quality analyzer 1, and a container 3 for holding coal is installed inside the rotating stage 2. An auxiliary component for preventing light interference is provided on the outside of the container 3. The auxiliary component includes a light shield 4 on the top of the container 3, and the light shield 4 is fitted outside the rotating stage 2. Sound insulation cotton 5 is installed inside the light shield 4.

[0025] Infrared spectroscopy is an analytical technique developed based on the differences in the absorption characteristics of different substances to infrared radiation. When infrared light from the coal quality analyzer 1 irradiates a coal sample, the organic and inorganic components in the coal selectively absorb infrared light of specific wavelengths, forming a unique infrared absorption spectrum. This absorption spectrum is closely related to the chemical composition, molecular structure, and physical state of the coal. By analyzing and interpreting the infrared spectrum, information about various components in the coal can be obtained, thereby achieving qualitative and quantitative analysis of the coal quality. This demonstrates that the diffuse reflectance of coal can encourage the coal quality analyzer 1 to collect more infrared light from the surface, enhancing the accuracy of detection.

[0026] Therefore, when the staff places the coal material on the cup 3 on the rotating table 2, the staff can put the light shield 4 on the outside of the rotating table 2. In this way, the light shield 4 can block the coal material and effectively block the stray light from the outside, ensuring that the coal quality analyzer 1 only receives the radiation signal of the coal material itself. The sound insulation cotton 5 inside the light shield 4 can absorb the vibration noise in the environment and reduce the indirect interference of noise to the coal quality analyzer 1, thereby improving the detection accuracy of the coal material.

[0027] Meanwhile, to ensure the stability of the light shield 4 and prevent it from loosening or separating, two spaced-apart inner rods 6 are installed on the top of the light shield 4. A fixing cylinder 7 is fitted around the top of each inner rod 6. Inside the fixing cylinder 7, from top to bottom, are a spring 8 and a positioning plate 9. The bottom end of the positioning plate 9 is fixed to the top end of the inner rod 6. The spring 8's rebound force pushes the positioning plate 9 and the inner rod 6 downwards, causing the inner rod 6 to move the light shield 4 downwards. This limits the movement of the light shield 4, preventing it from loosening or separating. The diameter of the positioning plate 9 is equal to the inner diameter of the fixing cylinder 7, and larger than the diameter of the inner rod 6. This allows the positioning plate 9 to limit the movement of the inner rod 6, preventing it from separating from the fixing cylinder 7 during movement and ensuring the stability of the inner rod 6 during displacement.

[0028] To improve the ease of operation of the light shield 4, each of the two fixed cylinders 7 is equipped with a fixed bracket 10 at its top, and the top of the fixed cylinder 7 is fixed to the bottom of the fixed bracket 10. The end of the fixed bracket 10 away from the fixed cylinder 7 is fixed to the top of the coal quality analyzer 1, and the top of the two fixed brackets 10 is equipped with the same adjusting rod 11. A connecting rope 12 is installed on the side of the adjusting rod 11 near the fixed cylinder 7, and the end of the connecting rope 12 away from the adjusting rod 11 passes through the fixed bracket 10 and is fixed to the top of the positioning plate 9. This allows the operator to pull the adjusting rod 11 outward to move the connecting rope 12 upward, which in turn moves the positioning plate 9 and the inner rod 6 upward. The inner rod 6 simultaneously moves the light shield 4 upward, causing the light shield 4 to separate and misalign with the coal, thus facilitating the operator's handling of the coal.

[0029] Furthermore, since the top of the fixed bracket 10 is equipped with a first retaining ring 13 and a second retaining ring 14, and the adjusting rod 11 is located on the side of the first retaining ring 13 away from the fixed cylinder 7, the operator can place the adjusted rod 11, after pulling it outward, at the second retaining ring 14. The second retaining ring 14 limits the adjustment rod 11, thereby preventing it from springing back. The first retaining ring 13 facilitates limiting the adjusted rod 11 after it springs back, preventing it from shaking. This improves the convenience of operating the adjusting rod 11.

[0030] To ensure the stability of the fixed bracket 10 and prevent it from collapsing, the fixed bracket 10 has an L-shaped cross section, and an inclined rod 15 to enhance stability is installed inside the fixed bracket 10. The inclined rod 15 can support and fix the fixed bracket 10, preventing it from twisting and collapsing.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
