Description

Technical Field

[0001] This invention relates to the field of intelligent identification and separation technology of valuable ore and waste ore in the mining process, specifically to a rotary solid-state microwave-induced intelligent ore identification test platform. Background Technology

[0002] During mining operations, a certain amount of waste rock inevitably gets mixed in, increasing the costs of downstream transportation, hoisting, crushing, grinding, and beneficiation. This is especially true in the mining of thin and fine veins, where beneficiation costs, energy consumption, and carbon emissions increase significantly. Using certain technical means to separate ore and waste rock during the mining stage—a process known as ore pre-selection and waste disposal—is an effective way to solve this problem.

[0003] Existing technologies include pre-selection and waste disposal methods such as manual sorting, color sorting, image recognition, X-ray fluorescence, laser, and X-ray transmission. However, all of these methods have certain drawbacks. Manual sorting is inefficient, labor-intensive, and costly. XRF estimates the grade of the entire ore by measuring the chemical composition of the ore surface, but its accuracy is low. Laser and near-infrared spectroscopy can only perform shallow surface detection and are suitable for single-particle sorting. X-ray transmission technology has limited penetration capabilities. These technologies cannot simultaneously meet the requirements of simplicity, accuracy, large-scale production, speed, efficiency, and low cost needed for ore pre-enrichment. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary solid-state microwave-induced intelligent ore identification test platform, which provides a fast, stable, reliable and accurate efficient means of separating valuable ores and waste rock for the research of solid-state microwave-induced intelligent ore identification technology, and realizes ore pre-selection and waste disposal.

[0005] To address the above problems, this invention provides a rotary solid-state microwave-induced intelligent ore identification test platform, the technical solution of which is as follows:

[0006] A rotary solid-state microwave-induced intelligent ore identification test platform includes a support system, a rotary conveyor belt, a drive motor, a solid-state microwave induction system, an infrared imaging system, a high-definition camera system, and a computer processing system.

[0007] The rotary conveyor belt and the conveyor motor are mounted on the support system. The conveyor motor is connected to the rotary conveyor belt to drive the rotary conveyor belt.

[0008] The solid-state microwave induction system is set above the straight section of the rotary conveyor belt to send solid-state microwave signals to the raw ore on the rotary conveyor belt.

[0009] The infrared imaging system is positioned above the straight section of the rotary conveyor belt to collect dynamic response data of the raw ore under solid-state microwave irradiation.

[0010] The computer processing system is signal-connected to the drive motor, the solid-state microwave induction system, the infrared imaging system, and the high-definition camera system. The computer processing system is configured as follows:

[0011] Based on the preset solid-state microwave radiation time, the running speed of the rotary conveyor belt is controlled by controlling the drive motor;

[0012] Control the solid-state microwave generation power of the solid-state microwave induction system and calculate the solid-state microwave absorbed energy.

[0013] Based on the absorbed energy of the solid-state microwave, and according to the difference in the dynamic response data of the raw ore under solid-state microwave irradiation collected by the infrared imaging system, the ore and waste rock are identified. The dynamic response data under solid-state microwave irradiation includes one or a combination of average gray level, variance, second moment energy, contrast, entropy value, and autocorrelation characteristic parameters.

[0014] The system acquires image data of the raw ore as it is transported on the rotary conveyor belt, collected by the high-definition camera system, in order to monitor any abnormalities in the raw ore after microwave irradiation.

[0015] Furthermore, the support system uses a microwave inert material that does not absorb microwave energy.

[0016] Furthermore, the two ends of the rotary conveyor belt are looped, the middle section is straight, and the connection is a rotary structure.

[0017] Furthermore, the rotary conveyor belt is made of a microwave inert material that does not absorb microwave energy.

[0018] Furthermore, the surface of the rotary conveyor belt is distributed with anti-slip texture.

[0019] Furthermore, the solid-state microwave induction system is connected to a computer processing system, and the distance between the system and the rotary conveyor belt is controlled by the computer processing system.

[0020] Furthermore, the solid-state microwave induction system includes a solid-state microwave generator, a solid-state microwave absorber, and a solid-state microwave power monitor;

[0021] The solid-state microwave generator is used to generate solid-state microwave signals, and the power and coverage of the generated solid-state microwaves are adjustable and controllable.

[0022] The solid-state microwave absorber is used to recover energy that was not absorbed by the raw ore and is located below the conveyor belt.

[0023] The solid-state microwave power monitor is used to monitor the microwave power of the solid-state microwave generator in real time.

[0024] The beneficial effects of this invention are as follows: According to an embodiment of the invention, a rotary solid-state microwave-induced intelligent ore identification test platform occupies a small area and can be used to complete experiments indoors. The use of a non-absorbent support system and a rotary conveyor belt saves space and allows for cyclical operation. By irradiating the ore with solid-state microwaves, an infrared imaging system can monitor the dynamic response of the ore under solid-state microwave irradiation in real time. Through a computer processing system, the differences in response between ore and waste rock are analyzed, enabling intelligent identification of ore and waste rock. Attached Figure Description

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0032] Solid-state microwaves possess selective heating properties and strong penetrating power. The sensitivity of minerals to microwave response is closely related to the type of material and its dielectric properties. In a solid-state microwave field, due to the different compositions of ores and waste rocks, microwave energy is absorbed by the medium and converted into heat required for heating, resulting in differences in the rate of temperature rise. Based on their temperature rise characteristics, minerals can be classified into three types: high-temperature rate minerals, medium-temperature rate minerals, and low-temperature rate minerals. Therefore, by measuring the temperature rise characteristics exhibited by minerals during microwave heating, different minerals can be distinguished, enabling pre-selection and disposal of waste ores.

[0033] The feasibility of solid-state microwave-induced ore sorting technology has been theoretically proven, but the development of related indoor test platforms is almost nonexistent.

[0034] Based on this, embodiments of the present invention provide a rotary solid-state microwave-induced intelligent ore identification test platform. For example... Figure 1 The diagram shown is a structural diagram of a rotary solid-state microwave-induced intelligent ore identification test platform. This platform includes a support system (not shown in the diagram), a rotary conveyor belt 1, a drive motor 8, a solid-state microwave induction system 5, an infrared imaging system 9, a high-definition camera system 4, and a computer processing system 6.

[0035] The rotary conveyor belt 1 and the conveyor motor 8 are mounted on the support system. The conveyor motor 8 is connected to the rotary conveyor belt 1 to drive the rotary conveyor belt 1.

[0036] It should be noted that the support system is used to support the rotary conveyor belt 1 and is equipped with a drive motor 8. It is preferably made of microwave inert material that does not absorb microwave energy, so as to avoid the support system being affected by microwave energy and improve the mineral differentiation accuracy.

[0037] The rotary conveyor belt 1 is used to transport raw ore. Figure 1 In this embodiment, the raw ore includes ore 2 and waste rock 3. The rotary solid-state microwave-induced intelligent ore identification test platform provided in this embodiment can identify ore 2 and waste rock 3.

[0038] For example, the rotary conveyor belt 1 has loops at both ends and a straight section in the middle, connected in a rotary structure for cyclic operation. The conveyor belt is located on the upper part of the support system, uses microwave inert material, does not absorb microwave energy, and has anti-slip textures on its upper surface to prevent the ore from sliding.

[0039] The drive motor 8 is used to drive the rotary conveyor belt and is connected to the computer processing system 6. The belt conveying speed is adjustable and controllable and can be automatically adjusted according to the changes in solid-state microwave power.

[0040] The solid-state microwave induction system 5 is set to correspond to the straight section of the rotary conveyor belt 1, so as to send solid-state microwave signals to the raw ore on the rotary conveyor belt to heat up the raw ore.

[0041] The solid-state microwave induction system 5 is connected to a computer processing system and is located above a straight conveyor belt. Its distance from the conveyor belt can be automatically controlled by the computer processing system. It includes a solid-state microwave generator, a solid-state microwave absorber, and a solid-state microwave power monitor. The solid-state microwave generator produces solid-state microwave signals, and the generated solid-state microwave power and coverage area are adjustable and controllable. The solid-state microwave absorber recovers energy not absorbed by the ore and is located below the conveyor belt. The solid-state microwave power monitor can monitor the microwave power of the solid-state microwave generator in real time.

[0042] The solid-state microwave induction system 5 is connected to a computer processing system, and its distance from the rotary conveyor belt 1 is controlled by the computer processing system 6. Structures that enable controllable distance between the solid-state microwave induction system 5 and the rotary conveyor belt 1 include, but are not limited to, mounting the solid-state microwave induction system 5 on a lifting platform. The computer processing system 6 controls the lifting platform to control the position of the solid-state microwave induction system 5, thereby achieving distance adjustment. The lifting platform includes, but is not limited to, a hydraulic lifting platform.

[0043] The infrared imaging system 9 is set to correspond to the straight section of the rotary conveyor belt 1 to collect dynamic response data of the raw ore under solid-state microwave irradiation.

[0044] The computer processing system 6 is signal-connected to the drive motor 8, the solid-state microwave induction system 5, the infrared imaging system 9, and the high-definition camera system 4. The computer processing system is configured as follows:

[0045] Based on the preset solid-state microwave radiation time, the speed of the rotary conveyor belt 1 is controlled by the drive motor 8 to ensure that both ore 2 and waste rock 3 can be heated at the preset solid-state microwave generation power, so as to facilitate the subsequent identification of ore 2 and waste rock 3 by the temperature rise rate.

[0046] Control the solid-state microwave generation power of the solid-state microwave induction system 5 and calculate the solid-state microwave absorbed energy.

[0047] Based on the absorbed energy of the solid-state microwave, and according to the differences in the dynamic response data of the raw ore under solid-state microwave irradiation collected by the infrared imaging system, the ore and waste rock are identified. The dynamic response data under solid-state microwave irradiation includes one or a combination of average gray level, variance, second moment energy, contrast, entropy value, autocorrelation characteristics and other parameters.

[0048] Understandably, the differences in the dynamic response data of the raw ore collected by the infrared imaging system 9 under solid-state microwave irradiation will reflect the temperature rise rate of ore 2 and waste rock 3 under known solid-state microwave absorption energy, thereby distinguishing ore 2 from waste rock 3. As an example only, one or a combination of the following parameters—average grayscale, variance, second-order moment energy, contrast, entropy, autocorrelation characteristics, and others—are compared with a corresponding preset identification threshold. If the preset identification threshold is reached, it is determined to be ore; otherwise, it is determined to be waste rock.

[0049] The high-definition camera system 4 acquires image data of the raw ore as it is transported on the rotary conveyor belt to monitor any abnormalities in the raw ore after microwave irradiation. For example, if the raw ore is found to have undergone shape changes under the influence of a certain solid-state microwave power, the solid-state microwave power can be adjusted, or the distance between the solid-state microwave induction system 5 and the rotary conveyor belt 1 can be adjusted to ensure that the identification of the raw ore can proceed normally.

[0050] It should be noted that the computer processing system 6 described in this article is an existing device capable of implementing the intelligent control process described above, such as an industrial computer, etc. Figure 1 The diagram shows an industrial computer deployed on a computer desk, where staff can input corresponding control parameters based on the computer processing system 6 to achieve intelligent identification of ore 2 and waste rock 3.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
