Description

Technical Field

[0001] This utility model relates to the field of mineral spectral detection technology, and in particular to a rapid detection device for fused spectra. Background Technology

[0002] Near-infrared spectroscopy (NIRS) and X-ray fluorescence (XRF) technologies are used to detect mineral materials and comprehensively analyze their composition. Specifically, the mineral materials are conveyed by belt conveyor and detected by NIRS and XRF technologies respectively. Finally, the data are summarized and analyzed to provide the detection results.

[0003] Currently, the X-ray fluorescence technology and near-infrared spectroscopy technology acquisition ports are placed at two acquisition points on the equipment, and the two acquisition points are only aligned on the axis in the direction of movement of the material to be tested. During the detection, the material chamber is in motion. Due to the non-uniformity of the material to be tested, the data collected by the two different detection methods at the same time are not for the same point of material, which will affect the accuracy of the data. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a fusion spectral rapid detection device to solve the problem that current X-ray fluorescence technology and near-infrared spectroscopy technologies have separate acquisition points, making it difficult to ensure that the same material is collected and detected at the same point.

[0007] Preferably, the angle between the X-ray emitting module, the X-ray acquisition module and the near-infrared emitting and acquisition module is 30°-40°.

[0011] Preferably, the bottom opening width of the feed hopper is smaller than the width of the conveyor belt.

[0012] Preferably, the top surface of the testing box has an open area, which is sealed and covered by a box lid.

[0013] The beneficial effects of this utility model are as follows: 1.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Fusion spectroscopy rapid detection equipment, such as Figure 1-3As shown, it consists of a conveyor box 1, a detection box 2, a conveyor belt 4, a detection unit, and a control system. The conveyor box 1 is a long strip-shaped box. The bottom of the conveyor box 1 is supported by several legs. An opening is opened at the left end of the top surface of the conveyor box 1, and a discharge port 11 is opened at the right end of the bottom surface of the conveyor box 1.

[0019] The conveyor belt 4 is installed inside the conveyor box 1. The conveyor belt 4 extends horizontally and is composed of a drive roller, a driven roller, and a belt body. The belt body is tensioned by the drive roller and the driven roller. The drive roller and the driven roller are rotatably connected to the conveyor box 1. A motor is connected and installed at one end of the shaft of the drive roller. The motor drives the drive roller to rotate, which is used to drive the belt body to convey the object to be tested in a straight line from left to right.

[0020] A feed hopper 3 is installed above the left end of the top surface of the conveyor box 1. The feed hopper 3 is inserted into the conveyor box 1 from the opening. The outside of the feed hopper 3 is connected to the conveyor box 1 through a cuboid frame 33. The feed hopper 3 is vertically connected so that the bottom opening of the feed hopper 3 faces the conveyor belt 4.

[0021] The detection box 2 is fixedly installed in the middle area of ​​the upper surface of the conveyor box 1. The X-ray emission module 5, the X-ray acquisition module 6, and the near-infrared emission and acquisition module 7 are all installed in the detection box 2 through brackets. The near-infrared emission and acquisition module 7 points vertically downwards towards the upper surface of the conveyor belt 4. The X-ray emission module 5 and the X-ray acquisition module 6 are distributed in a V-shape on both sides of the near-infrared emission and acquisition module 7. The detection directions of the X-ray emission module 5, the X-ray acquisition module 6, and the near-infrared emission and acquisition module 7 converge at a point on the surface of the conveyor belt 4. The angle between the X-ray emission module 5, the X-ray acquisition module 6 and the near-infrared emission and acquisition module 7 is the same, and the angle between the X-ray emission module 5, the X-ray acquisition module 6 and the near-infrared emission and acquisition module 7 is 30°-40°.

[0022] X-ray emission module 5 is used in conjunction with X-ray acquisition module 6. Both X-ray emission module 5 and X-ray acquisition module 6 are existing products, and their supporting high-voltage power supply, data output terminal and other components are also available. Near-infrared emission and acquisition module 7 consists of a near-infrared emitter, an infrared acquisition device, a composite optical cable and an optical fiber probe. All of these are existing technologies and will not be described in detail here. Working principle of this utility model: The shrunk material to be tested is fed into the conveyor belt 4 through the feed hopper 3 and transported below the detection unit. The X-ray emission module 5, X-ray acquisition module 6, and near-infrared emission and acquisition module 7 are pointed at a point on the surface of the material to be tested. The X-ray emission module 5 is turned on to emit X-ray photons to the detection point. The X-ray acquisition module 6 collects the fluorescence spectrum of the mineral material generated by the X-rays, processes it, and sends it to the data analysis component. The X-rays are used to detect the metal element content in the mineral material. The metal element content is used to feed back the compound content, thereby determining the ash content. The near-infrared emission and acquisition module 7 is activated to emit infrared light vertically downwards to the detection point and collect the reflected infrared light information of the detection point. This is used to detect the organic content in the mineral material. Combined with the above-mentioned detection of ash content, it can comprehensively judge the calorific value and other related characteristics of the mineral material. The X-ray source and the near-infrared source are combined into a point or a very small spot area to improve the accuracy of detection and avoid the difference in results caused by different measurement point positions. The detected material is discharged through the discharge port 11.

[0023] Near-infrared wavelengths range from 700 nanometers to 1.4 micrometers, while X-ray wavelengths range from 0.01 to 10 nanometers. Therefore, various signal data collected at the same point have minimal mutual influence, ensuring data accuracy and avoiding the data discrepancies that occur when measuring X-rays and near-infrared light at multiple points.

[0024] The bottom opening of the feed hopper 3 is in sliding contact with the surface of the conveyor belt 4. The width of the bottom opening of the feed hopper 3 is smaller than the width of the conveyor belt 4. The feed hopper 3 has an inclined extension 31 on the side near the conveyor belt 4 in the conveying direction. A guide port 32 is opened at the bottom of the end face of the inclined extension 31. The guide port 32 is rectangular. When the material to be tested is put onto the surface of the conveyor belt 4, the material can only be discharged from the guide port 32 due to the restriction of the bottom edge of the feed hopper 3. When the conveyor belt 4 drives the material to be discharged from the guide port 32, the guide port 32 scrapes the material, so that the material transmitted by the conveyor belt 4 is uniform in height, ensuring that the detection point where the X-ray emission module 5, X-ray acquisition module 6, and near-infrared emission and acquisition module 7 converge is always on the surface of the material. The inclined extension 31 provides a space for the scraped material.

[0025] The conveyor box 1 and the detection box 2 create a closed space for the conveying and detection of materials, avoiding the influence of the external environment on the material detection work. The top surface of the detection box 2 has an open area. The detection box 2 is rotatably connected to one side of the box cover 21, so that the box cover 21 can seal and cover the open area. By opening the box cover 21, it is convenient to inspect and maintain related devices such as the X-ray emission module 5, the X-ray acquisition module 6, and the near-infrared emission and acquisition module 7 through the open area.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
