Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a mineral processing equipment based on X-ray recognition. Background Technology

[0002] At mining sites, manual sorting and selection are widely used for preliminary separation of coarse-grained and mixed ores. Personnel visually inspect and manually assess the physical characteristics of the ore, such as its appearance, color, shape, and weight, to classify it. However, manual mineral processing has many drawbacks. For example, it is inefficient and prone to misjudgment and omissions due to operator fatigue and environmental interference, affecting the purity and quality of the minerals. Furthermore, the internal components of some minerals cannot be identified visually, making precise screening impossible through manual sorting alone, resulting in high loss rates of target minerals and low resource utilization.

[0003] Therefore, there is an urgent need for an automated mineral processing equipment based on X-ray recognition to replace traditional manual mineral processing and solve the technical defects of the aforementioned manual mineral processing. Summary of the Invention

[0004] The purpose of this invention is to provide a mineral processing device based on X-ray identification to solve the problems of misjudgment and missed selection caused by manual screening mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mineral processing equipment based on X-ray identification, comprising a support platform and an upper support. The upper support is fixedly connected to the top of the support platform, and a feeding conveyor belt is installed on the upper support. A gantry frame is provided at the tail of the feeding conveyor belt, covering it. Opening and closing motors are fixedly connected to both sides of the outer wall of the gantry frame. A rotating rod is fixedly connected to the output shaft of the opening and closing motor, and a stop gate is fixedly connected to the inner side of the rotating rod. The stop gate is located between the feeding conveyor belt and the gantry frame. A bucket frame is provided on the left side of the support platform, and a motor base is fixedly connected to the left side of the outer wall of the bucket frame. A steering motor is fixedly connected to the motor base, and a rotating shaft is fixedly connected to the output shaft of the steering motor. A sorting bucket is fixedly hung on the outside of the rotating shaft. An X-ray emitter is installed on the left side of the inner wall of the sorting bucket, and an X-ray receiver is installed on the right side of the inner wall of the sorting bucket. A trolley is provided on the lower left side of the sorting bucket, and a lower support is provided on the lower right side of the sorting bucket. A discharge conveyor belt is installed on the lower support.

[0006] As a further technical solution of this utility model, the rotating shaft is movably assembled in the bucket frame through a bearing seat, and the cross-section of the sorting bucket is trapezoidal.

[0007] As a further technical solution of this utility model, the X-ray emitter and X-ray receiver are arranged accordingly, and two sets of plastic baffles are provided in the sorting hopper to separate the emitter and receiver from the ore.

[0008] As a further technical solution of this utility model, the trolley is a human-powered cart with wheels at the bottom, used for collecting waste ore.

[0009] As a further technical solution of this utility model, the gate is provided in two sets, which are symmetrically arranged about the vertical center line of the gantry frame.

[0010] As a further technical solution of this utility model, a first spring is fixedly connected to the tail of the upper support, and an upper loading plate is fixedly connected to the top of the first spring. The upper loading plate is inclined towards the sorting hopper.

[0011] As a further technical solution of this utility model, the lower support is fixedly connected to a movable support leg, the top of the movable support leg is fixedly connected to a download plate, a second spring is installed at the connection point between the movable support leg and the lower support, and the download plate is inclined towards the discharge conveyor belt.

[0012] As a further technical solution of this utility model, the width of the sorting hopper is greater than that of the upper loading plate, and the width of the sorting hopper is less than that of the lower loading plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the mineral processing equipment based on X-ray recognition not only improves the accuracy and efficiency of sorting, controls the ore entering the sorting area, and enhances the recognition accuracy and sorting stability, but also ensures the safe and stable transmission of ore and reduces the risk of equipment failure.

[0014] (1) By setting up a feeding conveyor belt, gantry frame, door opening and closing motor, rotating rod, barrier door, sorting bucket, trolley, discharge conveyor belt, steering motor, rotating shaft, X-ray emitter, and X-ray receiver, the ore is first transported sequentially by the feeding conveyor belt. The internal composition data of the ore is obtained through X-ray analysis. When it is identified as the target ore, the PLC controls the steering motor to drive the rotating shaft to rotate the sorting bucket towards the discharge conveyor belt, and accurately discharges the target ore. When it is identified as a non-target ore, the PLC controls the sorting bucket to rotate towards the trolley, and discharges the waste rock into the trolley. Thus, ore sorting based on X-ray identification is realized, and the sorting accuracy and efficiency are improved.

[0015] (2) By setting up a barrier gate, a switch motor, a gantry frame, and a rotating rod, the gantry frame is equipped with two sets of barrier gates symmetrically arranged along its vertical center line. The barrier gate is opened and closed by the switch motor driving the rotating rod to effectively control the ore entering the sorting area, avoid ore accumulation or overlap, ensure the quantity of ore in the X-ray detection area, and improve the identification accuracy and sorting stability.

[0016] (3) By setting up an upper plate, a lower plate, a first spring, and a second spring, an upper plate is set below the feeding conveyor belt. Supported by the first spring, it can effectively reduce the impact when the ore falls into the sorting bucket, avoid ore damage and sorting bucket wear. At the same time, a lower plate is set above the discharge conveyor belt. It is connected to the movable support foot through the second spring, which can buffer the impact when the ore falls into the discharge conveyor belt, ensure safe and stable ore transmission, reduce equipment failure risk, and extend equipment service life.

[0022] 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.

[0023] Please see Figure 1-4This utility model provides an embodiment of a mineral processing device based on X-ray identification, comprising a support platform 3 and an upper support 2. The upper support 2 is fixedly connected to the top of the support platform 3, and a feed conveyor belt 1 is installed on the upper support 2. A gantry frame 4 is provided above the end of the feed conveyor belt 1. A bucket frame 12 is provided on the left side of the support platform 3, and a motor base 10 is fixedly connected to the left side of the outer wall of the bucket frame 12. A steering motor 17 is fixedly connected to the motor base 10, and a rotating shaft 18 is fixedly connected to the output shaft of the steering motor 17. A sorting bucket 1 is fixedly hung on the outside of the rotating shaft 18. 1. An X-ray emitter 19 is installed on the left side of the inner wall of the sorting bucket 11, and an X-ray receiver 20 is installed on the right side of the inner wall of the sorting bucket 11. A trolley 13 is set at the lower left of the sorting bucket 11, and a lower support 15 is set at the lower right of the sorting bucket 11. A discharge conveyor belt 16 is installed at the lower support 15. The rotating shaft 18 is movably assembled in the bucket frame 12 through a bearing seat. The cross-section of the sorting bucket 11 is trapezoidal. The X-ray emitter 19 and the X-ray receiver 20 are set accordingly. Two sets of plastic baffles 21 are set inside the sorting bucket 11 to separate the emitter and receiver from the ore.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the ore moves to the gate 7, one group of ore is allowed to pass through, while the remaining ore is blocked by the gate 7. This achieves precise control over the number of ore entering the sorting area and improves the identification accuracy. Subsequently, the ore falls from the upper plate 8 into the sorting hopper 11. The X-ray emitter 19 emits X-rays to the X-ray receiver 20. The X-rays penetrate the ore and are collected by the X-ray receiver 20. The internal composition data of the ore is obtained through analysis and transmitted to the external control system PLC in real time for judgment. When the target ore is identified, the PLC controls the steering motor 17 to drive the rotating shaft 18 to rotate the sorting hopper 11 towards the discharge conveyor belt 16, accurately exporting the target ore. When the non-target ore is identified, the PLC controls the sorting hopper 11 to rotate towards the trolley 13, discharging the waste rock into the trolley 13.

[0025] On both sides of the outer wall of the gantry frame 4, there are fixed opening and closing motors 5. The output shaft of the opening and closing motors 5 is fixedly connected to a rotating rod 6. A stop gate 7 is fixedly connected to the inner side of the rotating rod 6. The stop gate 7 is located between the feeding conveyor belt 1 and the gantry frame 4. There are two sets of stop gates 7, which are symmetrically arranged about the vertical center line of the gantry frame 4.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the gantry frame 4 is equipped with two sets of gates 7 symmetrically arranged along its vertical center line. The gates 7 are opened and closed by the rotating rod 6 driven by the door opening and closing motor 5.

[0027] The trolley 13 is a hand-operated trolley with wheels at the bottom, used for collecting waste ore. The upper support 2 is fixedly connected to the tail of a first spring 9, and the top of the first spring 9 is fixedly connected to an upper loading plate 8. The upper loading plate 8 is inclined toward the sorting hopper 11. The lower support 15 is fixedly connected to the outside of a movable support leg 22, and the top of the movable support leg 22 is fixedly connected to a downloading plate 14. A second spring 23 is installed at the connection point between the movable support leg 22 and the lower support 15. The downloading plate 14 is inclined toward the discharge conveyor belt 16. The width of the sorting hopper 11 is greater than that of the upper loading plate 8, and the width of the sorting hopper 11 is less than that of the downloading plate 14.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, an upper plate 8 is provided below the feed conveyor belt 1 and is supported by a first spring 9. This effectively reduces the impact of ore falling into the sorting hopper 11, preventing ore damage and wear of the sorting hopper 11. At the same time, a lower plate 14 is provided above the discharge conveyor belt 16 and is connected to the movable support leg 22 by a second spring 23. This buffers the impact of ore falling into the discharge conveyor belt 16, ensuring safe and stable ore transmission.

[0029] The computer software involved in the X-ray emitter 19 and X-ray receiver 20 carriers in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software involved in the aforementioned hardware carriers, nor is it a key technical point of the invention.

[0030] Therefore, it can be seen that the "feeding conveyor belt 1", "door opening and closing motor 5", "discharging conveyor belt 16", "steering motor 17" and other components involved in this application are all physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0031] Working Principle: The device uses X-ray identification technology for ore sorting. First, the feed conveyor belt 1 is started, driven by a variable frequency motor to run at a constant speed. The ore raw material moves forward along the feed conveyor belt 1 sequentially and enters the gantry 4 where the gate 7 is located. The gate 7 is opened and closed by a rotating rod 6 driven by a gate opening and closing motor 5. The two sets of gates 7 can precisely control the amount of ore entering the sorting hopper 11, avoiding ore stacking or overlapping. Then, the ore slides from the upper plate 8 into the sorting hopper 11. Supported by the first spring 9, hopper 8 provides a certain buffering effect, slowing down the ore's descent and reducing the impact on the sorting hopper 11, thus preventing ore breakage and equipment wear. After the ore enters the sorting hopper 11, the X-ray emitter 19 is activated, emitting a high-energy X-ray beam. This X-ray beam has strong penetrating power and can penetrate the interior of the ore. Different components and densities of the ore have different absorption coefficients for X-rays. According to Beer-Lambert's law I=I0e^-μx, elements with high atomic number inside the ore absorb X-rays. The X-rays are strongly absorbed by elements with low atomic numbers, while those with low atomic numbers are weakly absorbed. The X-ray receiver 20 receives the intensity of the remaining X-rays after penetrating the ore, forming a grayscale image of the ore. After digital conversion, the image is transmitted to the PLC control system. The image processing algorithm built into the PLC system analyzes the internal composition and content of the ore based on the received X-ray grayscale image and a preset recognition model to determine whether it is the target ore. When it is determined to be the target ore, the PLC issues a command to start the steering motor 17, which drives the rotating shaft 18 to rotate the sorting bucket 11 towards the discharge conveyor belt 16. The ore falls into the discharge conveyor belt 16 and is transported to the next process. If it is determined to be a non-target ore, the PLC controls the sorting bucket 11 to rotate towards the trolley 13. The ore is automatically poured into the trolley 13 for collection. During the process of the ore falling into the discharge conveyor belt 16, the download plate 14 is supported by the second spring 23 and the movable support leg 22, which also has a buffering function. It can effectively reduce the impact force of the ore and ensure that the ore enters the discharge conveyor belt 16 smoothly and safely for subsequent processing.

[0032] 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.
