Description

Technical Field

[0001] The utility model relates to the technical field of spectrometers, in particular to an on-line installation structure of a near-infrared spectrometer. Background Art

[0002] The near-infrared spectral analyzer is a common spectral analyzer that uses near-infrared laser as the light source. Currently, it is commonly used for the monitoring of flowing solids and liquids. A probe is installed on the near-infrared spectrometer, and the probe detects the passing materials. Since the near-infrared spectrometer is in a working state in the factory environment and continuously detects the materials, the materials continuously wash the position of the probe, which easily causes the probe to be soiled or worn. Therefore, it is best to avoid direct contact with the materials during installation, and at the same time, it is convenient for the disassembly and assembly of the near-infrared spectrometer for maintenance and repair. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an on-line installation structure of a near-infrared spectrometer.

[0004] The utility model is realized through the following technical solutions. An on-line installation structure of a near-infrared spectrometer is provided, which includes a near-infrared spectrometer. A protruding probe is provided on the bottom surface of the near-infrared spectrometer. An installation plate is further included that fits on the bottom surface of the near-infrared spectrometer. The near-infrared spectrometer is detachably fixed to the installation plate. A probe hole for the probe to pass through is opened on the installation plate. A transparent plate is installed on the bottom surface of the installation plate. A pressing ring that presses the transparent plate against the lower end surface of the probe hole is bolted to the bottom surface of the installation plate.

[0005] During installation, first place the transparent plate at the position of the probe hole on the lower end surface of the installation plate, and connect and fix the pressing ring to the connecting plate through bolts, thereby realizing the fixation of the transparent plate. Weld or bolt the installation plate to the installation position so that the lower end surface of the installation plate fits the material to be detected. Fix the near-infrared spectrometer to the top surface of the installation plate, and insert the probe of the near-infrared spectrometer into the probe hole of the installation plate. The material passes under the transparent plate, and the probe detects the material.

[0006] As an optimization, connecting screws are hinged at both ends of the installation plate. Ear plates are fixed at both ends of the near-infrared spectrometer. A screw groove adapted to the connecting screw is opened at the end of the ear plate. A connecting nut that presses the ear plate against the installation plate is installed on the connecting screw. In this solution, the swinging connecting screw swings to the screw groove at the end of the ear plate, and the connecting nut is tightened to realize the fixation of the near-infrared spectrometer. This fixation method is convenient and fast for disassembly and assembly.

[0007] As an optimization, protruding connecting parts are provided at both ends of the installation plate, and one end of the connecting screw is hinged to the connecting part. The protruding connecting part in this solution is used to realize the hinge connection with the connecting screw.

[0008] As an optimization, the connecting nut is a wing nut, which facilitates the rotation of the wing nut by hand and improves the convenience of disassembly and assembly.

[0009] As an optimization, an annular protrusion is provided on the upper end surface of the pressing ring, the transparent plate is located inside the inner circle of the annular protrusion, and an annular groove adapted to the annular protrusion is provided on the bottom surface of the mounting plate. Thereby, the size of the bottom surface of the pressing ring protruding from the bottom surface of the connecting plate is reduced, and the influence on the flow of materials is reduced.

[0010] As an optimization, a circle of threaded holes is opened on the upper end surface of the annular protrusion, bolt holes adapted to the threaded holes are opened on the mounting plate, and bolt head counterbores are opened at the upper ends of the bolt holes. The pressing ring is connected by bolts to the bolt holes, and the bolt head counterbores are used to accommodate the bolt heads of the bolts.

[0011] As an optimization, the lower end surface of the mounting plate is flush with the lower end surface of the probe. Thereby, the transparent plate is attached to the lower end surface of the probe, and the detection distance is reduced.

[0012] The beneficial effects of the present utility model are as follows: An on-line installation structure of a near-infrared spectrometer according to the present utility model protects the probe of the near-infrared spectrometer through a transparent plate supported by a sapphire glass plate, thereby reducing the impact on the probe model and ensuring the detection accuracy at the same time. The near-infrared spectrometer is installed through the mounting plate, improving the disassembly and assembly efficiency, facilitating maintenance and reducing the impact time on the production line.

[0023] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation modes.

[0024] As Figures 1 - 8 shown, an on-line installation structure of a near-infrared spectrometer of the present utility model includes a near-infrared spectrometer 1. The bottom surface of the near-infrared spectrometer 1 is provided with a protruding probe. The probe is a protruding cylindrical structure, and a detection module is located inside the probe for detecting materials.

[0025] It further includes a mounting plate 2 attached to the bottom surface of the near-infrared spectrometer 1. The mounting plate 2 is a metal plate, and its shape and size are the same as those of the near-infrared spectrometer 1. The near-infrared spectrometer 1 is detachably fixed to the mounting plate 2.

[0026] In order to achieve the detachable fixation of the near-infrared spectrometer 1, in this embodiment, connecting screws 4 are hinged at both ends of the mounting plate 2. Specifically, protruding connecting parts are provided at both ends of the mounting plate 2, and one end of the connecting screw 4 is hinged to the connecting part, and the hinge axis is parallel to the mounting plate 2, so that the connecting screw 4 can swing up and down.

[0027] Ear plates 3 are fixedly connected to both ends of the near-infrared spectrometer 1. The ear plates 3 are horizontal plates and the lower ends are flush with the lower end of the near-infrared spectrometer 1. A screw groove adapted to the connecting screw 4 is opened at the end of the ear plate 3. Here, the end refers to the end of the ear plate 3 away from the near-infrared spectrometer 1. The width of the screw groove is slightly larger than the diameter of the connecting screw 4, and the depth of the screw groove is 2 - 4 times the diameter of the connecting screw 4.

[0028] A connecting nut 5 for pressing the ear plate 3 against the mounting plate 2 is installed on the connecting screw 4. The connecting nut 5 is a wing nut.

[0029] A probe hole for the probe to pass through is opened on the mounting plate 2. The probe hole is a circular hole and its diameter is equal to the diameter of the probe. The thickness of the mounting plate 2 is equal to the length of the probe, so that the lower end surface of the mounting plate 2 is flush with the lower end surface of the probe.

[0030] A transparent plate 8 is installed on the bottom surface of the mounting plate 2. The mounting plate 2 is a circular plate and its diameter is larger than the diameter of the probe. In this embodiment, the transparent plate is made of sapphire glass plate, which has high hardness and good light transmittance.

[0031] The bottom surface of the mounting plate 2 is bolted with a pressing ring 7 that presses the transparent plate 8 against the lower end surface of the probe hole. The thickness of the pressing ring 7 should be as small as possible to reduce the impact on the material and make the material as close to the transparent plate 8 as possible.

[0032] The upper end surface of the pressing ring 7 is provided with an annular protrusion. The transparent plate 8 is located inside the inner circle of the annular protrusion. The bottom surface of the mounting plate 2 is provided with an annular groove adapted to the annular protrusion.

[0033] A circle of threaded holes is opened on the upper end surface of the annular protrusion. Bolt holes adapted to the threaded holes are opened on the mounting plate 2. Bolt head counterbores are opened at the upper ends of the bolt holes.

[0034] The usage method of the present utility model:

[0035] During installation, first place the transparent plate 8 at the position of the probe hole on the lower end surface of the mounting plate 2. Insert the annular protrusion of the pressing ring 7 into the annular groove of the connecting plate 2, and connect and fix the pressing ring 7 and the connecting plate 2 through bolts, thereby realizing the fixation of the transparent plate 8.

[0036] Weld or bolt the mounting plate 2 to the installation position so that the lower end surface of the mounting plate is in contact with the material to be detected. Place the near-infrared spectrometer 1 on the top surface of the mounting plate 2, insert the probe of the near-infrared spectrometer 1 into the probe hole of the mounting plate 2, then swing the connecting screw 4 so that the connecting screw 4 swings into the screw groove at the end of the ear plate 3, and tighten the connecting nut 5 to realize the fixation of the near-infrared spectrometer 1. The material passes under the transparent plate 8, and the probe is used to detect the material.
