Description

Technical Field

[0001] This invention relates to the field of ore sorting technology, and in particular to a barite ore sorting and sorting machine based on industrial vision. Background Technology

[0002] In modern sorting processes for industrial minerals such as barite, intelligent sorting technology based on industrial vision has become a key technological route for improving resource recovery rates and product quality due to its advantages such as non-contact operation, high efficiency, and high precision. Current mainstream solutions typically consist of core modules such as feeding and dispersion, optical detection, and pneumatic or mechanical picking. Specifically, to obtain clear images of the ore, existing technologies use vibratory feeding or inclined chute systems to achieve initial monolayering and dispersion of the ore; subsequently, an industrial camera captures the surface optical features of the ore under specific light sources, and image processing algorithms are used for identification and classification; finally, the control system drives high-pressure nozzles or robotic arms to separate the target ore from the raw material flow. To improve the accuracy of identifying ores with wet surfaces or attached impurities, some improved solutions introduce a pretreatment stage, such as adding a simple ambient temperature airflow purging device before detection to remove some surface dust and residual moisture.

[0003] However, the aforementioned existing technical solutions exhibit a series of inherent technical limitations when processing ores with highly adhesive impurities or moist surfaces. First, conventional single-airflow purging has limited effectiveness in removing fine particles adhering to the ore surface due to static electricity, grease, or water film, and is particularly ineffective in removing stubborn impurities embedded in surface pits or deep textures. This results in the pre-treated ore surface still not being an ideal optical detection plane, directly affecting the accuracy and reliability of subsequent visual recognition. Secondly, existing pretreatment units mostly operate with fixed parameters and lack the ability to adaptively adjust key conditions such as particle size and humidity of incoming ore. It is difficult to dynamically optimize core parameters such as airflow intensity and temperature according to real-time changes in materials, often leading to problems such as excessive blowing of small-diameter ore or incomplete processing of large-diameter ore. It is difficult to balance pretreatment efficiency and energy consumption. Furthermore, the traditional single-sided processing and detection mode has inherent blind spots. The bottom surface of the ore in contact with the conveyor surface cannot be effectively cleaned and imaged, which can easily cause impurity residue and misjudgment of quality.

[0004] Therefore, this application provides a barite ore sorting and sorting machine based on industrial vision to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a barite ore sorting and sorting machine based on industrial vision, so as to solve the problems that existing ore pretreatment technology is difficult to effectively remove stubborn impurities on the surface of wet and sticky ore, lacks the ability to adaptively adjust airflow and heat field for ores of different particle sizes, and single-sided processing leads to bottom surface cleaning and detection blind spots, which seriously affect the optical sorting accuracy.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A barite ore sorting and distributing device based on industrial vision includes a support frame and a conveyor belt assembled inside it. A high-precision vision inspection instrument, a dynamic hot-film mechanism, and a high-speed vision sensor are sequentially arranged on one side of the support frame from bottom to top. A flipping mechanism and a feeding mechanism are respectively arranged above. The guiding component of the feeding mechanism consists of an adjustable "V"-shaped opening formed by a hinged first and second inclined plate, allowing the ore to fall in a single layer. The high-speed vision sensor collects information on the surface humidity, dirt, and particle size of the ore in real time and transmits it to a control center. The dynamic hot-film mechanism includes a hot air cavity, a built-in ultrasonic transducer, and a heating rod. The air outlet chamber and high-pressure vortex fan are equipped with two sets of ultrasonic transducers arranged along the upper and lower sides of the inner wall of the hot air cavity, with their vibration direction forming a 15° angle with the hot air flow axis. The high-pressure vortex fan is electrically connected to a frequency converter, which receives the particle size signal output by the high-speed vision sensor and adjusts the output frequency. The rebound plate in the ore impact turning mechanism realizes automatic turning, and the stripped particles are introduced into the particle recovery box through the output pipe. The high-speed vision sensor, dynamic hot film mechanism, turning mechanism and high-precision vision inspection instrument are arranged in sequence along the same barite free fall trajectory, together forming an optical ready pretreatment optical path for wet and sticky materials.

[0007] Optionally, a bracket is fixedly connected to the bottom of the hot air cavity, one side of the bottom end of the bracket is fixedly connected to the support frame, and the side near the top end is connected to a high-precision vision inspection instrument. The air outlet chamber is fixedly installed at the output end of the hot air cavity.

[0008] Optionally, the top surface of the air outlet chamber is fixedly connected to the bottom surface of the high-speed vision sensor by bolts, a dustproof net is fixedly installed at the output end of the air outlet chamber, and the heating rod is located downstream of the input end of the heating rod along the airflow direction and is rigidly fixedly connected to the inner wall of the hot air cavity.

[0009] Optionally, the input end of the hot air cavity is connected to the air inlet port, and the two are rigidly sealed by a flange and a high-temperature resistant sealing ring. The input end of the air inlet port is coaxially connected to the output end of the high-pressure vortex fan, forming a leak-free forced airflow path from the high-pressure vortex fan through the air inlet port to the hot air cavity.

[0010] Optionally, a sealing door is hinged to one side of the pellet recycling box, and a fixed frame is fixedly connected to the bottom. The bottom end of the fixed frame is fixedly connected to the outer surface of the support frame. A positioning frame is fixedly installed on the other side of the pellet recycling box, and a buffer cavity is fixedly connected to one side of the positioning frame.

[0011] Optionally, the buffer cavity is provided with a buffer plate inside. The buffer plate includes a first fixing plate fixedly connected to the inner wall of the buffer cavity. A plurality of buffer damping rods are arranged in a rectangular array on one side of the first fixing plate, and one end of the plurality of buffer damping rods is fixedly connected to a second fixing plate.

[0012] Optionally, a power chamber is fixedly connected to one side of the second fixed plate, and a rebound plate is fixedly connected to the output end of the power chamber. The rebound plate is composed of multiple parallel wear-resistant rubber strips with gaps between adjacent rubber strips. The power chamber has an air inlet at the position corresponding to the gap, so that the airflow passes through the air inlet and through the gap to transport the particles separated by the rebound.

[0013] Optionally, a surrounding plate is fixedly connected to the outer periphery of the buffer cavity, the output end of the power chamber is connected to the output pipe, and the output end of the output pipe is connected to the particle recovery box. A power pump is fixedly installed on the front of the particle recovery box to provide airflow conveying power.

[0014] Optionally, a rectangular cavity is fixedly connected to the top of the pellet recycling box, a vibrator is installed at one end of the rectangular cavity, the output end of the vibrator is fixedly connected to the shaking plate, a damping column is provided at the bottom of the shaking plate, and the lower end of the damping column is fixedly connected to the inner bottom wall of the rectangular cavity, which is used to suppress the vibration amplitude of the shaking plate and improve the stability of material conveying. A flow guiding assembly is provided above the rectangular cavity. The flow guiding assembly includes a first inclined plate and a second inclined plate that are hinged to each other. A first fixed rod and a second fixed rod are fixedly connected to the bottom of the two plates respectively. Both the first fixed rod and the second fixed rod have coaxial threaded holes and are connected by a fixed bolt to adjust the included angle between the first inclined plate and the second inclined plate to form an adjustable figure-eight opening.

[0015] The second objective of this invention is to provide a barite ore sorting machine based on industrial vision, applicable to any of the above-mentioned barite ore sorting and dispensing devices based on industrial vision, including a sorting machine assembly. The sorting machine assembly includes a cylinder fixedly connected to the back of the support frame and a receiving bin on the front. An arc-shaped plate is fixedly connected to the output end of the cylinder.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In this invention, the optimized design of the dynamic hot film mechanism enables efficient dehydration and decontamination treatment of wet and sticky ores. Two sets of ultrasonic transducers arranged on the upper and lower sides of the hot air chamber vibrate at a specific angle to the axis of the hot air flow. Combined with the forced airflow formed by the built-in heating rod and the high-pressure vortex fan, the ultrasonic vibration and the hot air flow work together on the surface of the ore. This not only allows for the rapid evaporation of surface moisture through heating, but also removes stubborn impurities with the help of ultrasonic vibration. At the same time, the dustproof net at the output end of the air chamber prevents impurities from flowing back, ensuring the cleanliness of the ore surface after pretreatment and providing a clear object for optical detection.

[0017] Most importantly, the high-pressure eddy current blower is linked with a high-speed vision sensor through a variable frequency drive. It can dynamically adjust the output frequency according to the real-time collected ore particle size information, so as to achieve precise adaptation of the hot air flow intensity. It optimizes the pretreatment parameters for different particle sizes of ore, avoiding the problem of blow-off deviation caused by a single airflow intensity for small-particle-size ore and incomplete pretreatment of large-particle-size ore, thus improving the targeting and energy saving of pretreatment.

[0018] In this invention, the coordinated design of the flipping mechanism and the particle recovery component further improves the pretreatment effect. The impact of the ore on the rebound plate, which is made of wear-resistant rubber strips, enables automatic flipping, ensuring that both the upper and lower surfaces of the ore can be fully pretreated and inspected, avoiding impurity residue and inspection errors caused by single-sided treatment. The gap between adjacent rubber strips, combined with the air inlet at the corresponding position of the power chamber, allows the rebounded and peeled particles to be guided into the particle recovery box through the output pipe by the airflow, realizing the timely separation and recovery of impurities. At the same time, the combination of the buffer damping rod and the fixed plate inside the buffer cavity can effectively buffer the impact force generated by the ore hitting the rebound plate, reduce equipment wear, and extend service life.

[0019] In this invention, the adjustable figure-eight-shaped opening guide component in the feeding mechanism, consisting of a hinged first inclined plate and a second inclined plate, can achieve single-layer ore drop by adjusting the included angle. This effectively avoids the detection blind spots and insufficient pretreatment caused by multi-layer ore stacking. At the same time, the combined design of the shaking plate above the rectangular cavity, the vibrator, and the damping column can both assist in the uniform distribution of materials through vibration and suppress the vibration amplitude with the help of the damping column, thereby improving the stability of material conveying and ensuring that each piece of ore can fully accept subsequent pretreatment and detection, thus improving the uniformity and consistency of the overall processing.

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features, and effects of the present invention.

[0023] like Figures 1 to 10As shown, an embodiment of the present invention provides a barite ore sorting and distributing device based on industrial vision, including a support frame 100 and a conveyor belt 101 assembled inside it. A high-precision vision inspection instrument 200, a dynamic hot-film mechanism 300, and a high-speed vision sensor 201 are sequentially arranged from bottom to top on one side of the support frame 100. A flipping mechanism 400 and a feeding mechanism 500 are respectively arranged above it. The flow guiding component 504 of the feeding mechanism 500 forms an adjustable "V"-shaped opening by a hinged first inclined plate 5041 and a second inclined plate 5042, allowing the ore to fall in a single layer. The high-speed vision sensor 201 collects information on the surface humidity, dirt, and particle size of the ore in real time and transmits it to the control center. The dynamic hot-film mechanism 300 includes a hot air cavity 301 and a built-in ultrasonic transducer. The ultrasonic transducer 302, along with the heating rod 305, the air outlet chamber 303, and the high-pressure vortex fan 307, consists of two sets of ultrasonic transducers 302 arranged along the upper and lower sides of the inner wall of the hot air cavity 301, with their vibration direction forming a 15° angle with the axis of the hot air flow. The high-pressure vortex fan 307 is electrically connected to the frequency converter, which receives the particle size signal output by the high-speed vision sensor 201 and adjusts the output frequency. The rebound plate 404 in the ore impact turning mechanism 400 achieves automatic turning, and the stripped particles are introduced into the particle recovery box 407 through the output pipe 406. The high-speed vision sensor 201, the dynamic hot film mechanism 300, the turning mechanism 400, and the high-precision vision inspection instrument 200 are arranged sequentially along the same free fall trajectory of barite, together forming an optically ready pretreatment optical path for wet and sticky materials.

[0024] It is worth mentioning that the aforementioned 15° angle setting has been verified by flow field simulation and experiments. It can form a moderate lateral disturbance component in the mainstream direction of hot airflow, which not only avoids the rapid attenuation of ultrasonic energy along the airflow axis, but also promotes the generation of a focused cavitation area of ​​sound waves near the ore surface, significantly enhancing the stripping efficiency of electrostatic adsorption fine dust. Compared with vertical (0°) or large angle (>30°) arrangement, the 15° angle configuration achieves the optimal balance between energy consumption, dust removal effect and airflow stability, and is one of the key parameters for achieving an "optically ready" surface state.

[0025] As can be seen from the above, the ore first falls uniformly in a single layer through the adjustable figure-eight shaped guide component 504 in the feeding mechanism 500, laying the foundation for subsequent accurate identification. The high-speed vision sensor 201 located upstream of the falling path captures the surface humidity, dirt level and particle size information of the ore in real time and transmits the data to the control center. The control center dynamically adjusts the working parameters of the dynamic hot film mechanism 300 accordingly. The high-pressure vortex fan 307 responds to the particle size signal through the frequency converter driver and adjusts the air volume. The ultrasonic transducers 302 arranged symmetrically in the hot air cavity 301 inject high-frequency vibration energy into the hot air flow at a 15° angle, so that the fine dust and water film attached to the surface of the ore are efficiently stripped off under the synergistic effect of ultrasonic cavitation and hot air.

[0026] Subsequently, the ore impacts the rebound plate 404 in the flipping mechanism 400, completing the automatic flipping and fully exposing all surfaces. At the same time, the damping structure absorbs the impact to prevent the ore from breaking. During this process, the stripped impurity particles are introduced into the particle recovery box 407 through the output pipe 406 for clean separation. In the entire system, the high-speed vision sensor 201, the dynamic hot film mechanism 300, the flipping mechanism 400, and the high-precision vision inspection instrument 200 are arranged sequentially along the same free fall trajectory, forming a continuous and closed "optically ready" pre-processing optical path. This design not only effectively solves the problem of identification difficulties caused by surface contamination, moisture coverage, or posture occlusion of wet and sticky ore, but also significantly improves the imaging quality and component discrimination accuracy of subsequent high-precision vision inspection, thus providing a reliable prerequisite for efficient and high-purity intelligent sorting of barite.

[0027] like Figures 2 to 6 As shown, a bracket is fixedly connected to the bottom of the hot air chamber 301. One side of the bottom end of the bracket is fixedly connected to the support frame 100, and the side near the top end is connected to the high-precision vision inspection instrument 200. The air outlet chamber 303 is fixedly installed at the output end of the hot air chamber 301. The top surface of the air outlet chamber 303 is fixedly connected to the bottom surface of the high-speed vision sensor 201 by bolts. A dustproof net 304 is fixedly installed at the output end of the air outlet chamber 303. The heating rod 305 is located downstream of the input end of the heating rod 305 along the airflow direction and is rigidly fixedly connected to the inner wall of the hot air chamber 301. The input end of the hot air chamber 301 is connected to the air inlet port 306. The two are rigidly sealed by a flange and a high-temperature resistant sealing ring. The input end of the air inlet port 306 is coaxially connected to the output end of the high-pressure vortex fan 307, forming a leak-free forced airflow path from the high-pressure vortex fan 307 through the air inlet port 306 to the hot air chamber 301.

[0028] Specifically: First, the control center adopts a rule-based and feedback-based composite control strategy to normalize the grayscale value (reflecting humidity), texture complexity (reflecting dirt), and pixel projection size (reflecting particle size) of the ore surface collected by the high-speed vision sensor 201, and compares them with the preset experience parameter database to dynamically calculate and output the target temperature value of the heating rod 305, the power duty cycle of the ultrasonic transducer 302, and the target frequency of the high-pressure vortex fan 307. Secondly, the "optically ready" state is defined as the physical conditions that the ore surface reaches after pretreatment, which allow the high-precision visual inspection instrument 200 to reliably image and analyze it. Its specific quantitative indicators are: the water film on the ore surface is basically removed (the surface reflectivity is lower than the preset threshold), the main visible surface (≥85%) is free of attached impurities with a particle size greater than 100 micrometers, and the ore is in a stable posture on the conveyor belt 101. The achievement of this state is verified by the imaging clarity and recognition confidence of the downstream high-precision visual inspection instrument 200 in a closed loop. Furthermore, to ensure efficient dust collection by negative pressure airflow, the sides of adjacent wear-resistant rubber strips in the rebound plate 404 are machined with tenon or groove structures and filled with flexible sealing strips, so that after being pressed with the mounting surface of the power chamber 403, it forms a sealed cavity that retains only the gap as the main airflow channel; finally, the key process parameters are as follows: the hot air temperature is adjustable between 50℃ and 150℃ based on the ore characteristics, the ultrasonic transducer 302 operates at a frequency of 20kHz to 40kHz, and the output frequency of the high-pressure vortex fan 307 is proportionally adjusted within the range of 30Hz to 80Hz according to the ore particle size signal.

[0029] As can be seen from the above, the hot air chamber 301 is rigidly connected to the support frame 100 and the high-precision vision inspection instrument 200 through a bracket, which not only ensures the structural stability of the dynamic hot film mechanism 300 during operation, but also ensures that its spatial positional relationship with the upper and lower vision inspection units remains constant, avoiding optical path deviation due to vibration or thermal deformation; the air outlet chamber 303 is bolted to the high-speed vision sensor 201, and a dustproof net 304 is set at the output end to effectively prevent dust backflow and contamination of the sensor; the heating rod 305 is arranged downstream of the airflow and rigidly fixed to the inner wall of the chamber, and together with the flange and high-temperature sealing ring to form a leak-free air inlet passage, the airflow generated by the high-pressure vortex fan 307 is efficiently heated and ultrasonically coupled to form a stable, clean, and controllable hot air curtain, ensuring the consistency and sealing of the hot airflow parameters, providing a reliable energy carrier for the evaporation of water film and the removal of micro-dust on the surface of wet and sticky ore, and significantly improving the repeatability and environmental adaptability of the pretreatment effect.

[0030] like Figures 6 to 8As shown, a sealed door is hinged to one side of the pellet recycling bin 407, and a fixed frame is fixedly connected to the bottom. The bottom end of the fixed frame is fixedly connected to the outer surface of the support frame 100. A positioning frame is fixedly installed on the other side of the pellet recycling bin 407. A buffer cavity 401 is fixedly connected to one side of the positioning frame. A buffer plate 402 is provided inside the buffer cavity 401. The buffer plate 402 includes a first fixed plate fixedly connected to the inner wall of the buffer cavity 401. Multiple buffer damping rods are arranged in a rectangular array on one side of the first fixed plate, and one end of each buffer damping rod is fixedly connected to a second fixed plate. One side of the second fixed plate is fixed... A power chamber 403 is connected, and a rebound plate 404 is fixedly connected to the output end of the power chamber 403. The rebound plate 404 is composed of multiple parallel wear-resistant rubber strips with gaps between adjacent rubber strips. An air inlet is provided at the corresponding gap position of the power chamber 403 so that the airflow passes through the gap through the air inlet for conveying the particles separated by the rebound. A surrounding plate 405 is fixedly connected to the outer periphery of the buffer cavity 401. The output end of the power chamber 403 is connected to the output pipe 406, and the output end of the output pipe 406 is connected to the particle recovery box 407. A power pump 408 is fixedly installed on the front of the particle recovery box 407 for providing airflow conveying power.

[0031] From the above, we can conclude that: The particle recovery box 407 is securely connected to the support frame 100 via a fixed frame and is equipped with an openable and closable sealing door for easy cleaning of impurities and maintenance of system airtightness. The buffer chamber 401 integrated on its side has a multi-point elastic support structure composed of double fixed plates and buffer damping rods, which can effectively absorb the impact energy transmitted during the rebound process. The rebound plate 404 connected to the power chamber 403 adopts an array of wear-resistant rubber strips with gaps, which, together with the air inlet at the corresponding position, allows the airflow to accurately pass through the gaps and blow the stripped fine particles to the output pipe 406. Finally, the power pump 408 draws them into the recovery box. This structure realizes the simultaneous completion of ore turning and impurity separation, which not only protects the ore from hard impact damage, but also efficiently collects debris through directional airflow, greatly improving the sorting purity and equipment operation reliability.

[0032] like Figure 8 and Figure 9As shown, a rectangular cavity 501 is fixedly connected to the top of the pellet recycling box 407. A vibrator 502 is installed at one end of the rectangular cavity 501. The output end of the vibrator 502 is fixedly connected to the shaking plate 503. A damping column is provided at the bottom of the shaking plate 503. The lower end of the damping column is fixedly connected to the inner bottom wall of the rectangular cavity 501 to suppress the vibration amplitude of the shaking plate 503 and improve the stability of material conveying. A flow guiding assembly 504 is provided above the rectangular cavity 501. The flow guiding assembly 504 includes a first inclined plate 5041 and a second inclined plate 5042 that are hinged to each other. A first fixing rod 5043 and a second fixing rod 5044 are fixedly connected to the bottom of the two plates respectively. Both the first fixing rod 5043 and the second fixing rod 5044 are provided with coaxial threaded holes and are threadedly connected by a fixing bolt 5045 to adjust the included angle between the first inclined plate 5041 and the second inclined plate 5042 to form an adjustable figure-eight opening.

[0033] From the above, we can conclude that: The top of the rectangular cavity 501 is integrated onto the particle recovery box 407. The vibrator 502 drives the swaying plate 503 to generate controllable vibration, and the bottom damping column suppresses excessive oscillation, so that the falling ore is conveyed forward evenly under stable disturbance, avoiding accumulation or blockage. The upper guide component 504 adopts a hinged double inclined plate structure. By adjusting the screw depth of the fixing bolt 5045 in the coaxial threaded hole, the opening angle of the figure-eight shape can be flexibly changed, thereby adapting to the single-layer material feeding requirements of different particle sizes of ore. This achieves dynamic matching of feeding width and flow rate, ensuring that the ore enters the falling trajectory in a dispersed, single-layer state, providing ideal initial conditions for subsequent visual recognition and pre-processing, and significantly improving the adaptability of the whole machine to complex incoming materials.

[0034] The second objective of this invention is to provide a barite ore sorting machine based on industrial vision, such as... Figures 1 to 10 As shown, the system includes a picking machine assembly 600, which includes a cylinder 601 fixedly connected to the back of the support frame 100 and a receiving bin 603 on the front. An arc-shaped plate 602 is fixedly connected to the output end of the cylinder 601.

[0035] From the above, we can conclude that: The sorting machine assembly 600 achieves a compact, efficient, and precise sorting execution mechanism by fixing the cylinder 601 to the back of the support frame 100, placing the receiving bin 603 on the front, and driving the arc plate 602 with the output end of the cylinder 601. After the high-precision vision inspection instrument 200 completes the ore composition identification, the cylinder 601 quickly responds to the control signal, pushing the arc plate 602 to extend precisely along a horizontal or preset trajectory, smoothly conveying the target ore to the front receiving bin 603. The curved surface design of the arc plate 602 conforms to the shape of the ore, reducing collision damage. The arrangement of the cylinder 601 and the receiving bin 603 on the front and rear sides of the frame makes full use of the equipment space and avoids the execution mechanism from interfering with the upstream vision inspection and pre-processing optical path, ensuring that the sorting action is fast, reliable, and unobstructed, significantly improving the accuracy, processing efficiency, and system integration of barite sorting.

[0036] Specifically, the high-precision visual inspection instrument 200 and the high-speed visual sensor 201 respectively undertake the visual perception tasks at different stages of the ore sorting process, and the two complement each other in terms of spatial layout and function. The high-speed visual sensor 201 is located in the area above the ore falling path. During the single-layer descent of the ore through the adjustable "eight"-shaped guide opening of the feeding mechanism 500, it captures dynamic images of the ore surface in real time at a high frame rate. Through the built-in image processing module, it analyzes and obtains key parameters such as the surface humidity, degree of attached dirt, and particle size of the ore, and transmits the data to the control center in real time. The control center dynamically adjusts the wind speed of the high-pressure vortex fan 307 in the dynamic hot film mechanism 300 according to this, so that the hot air and ultrasonic waves can be precisely applied to the ore surface. Subsequently, the ore impacts the rebound plate 404, completing the flipping action and entering the inspection station. At this time, the high-precision vision inspection instrument 200, located under the support frame 100, performs high-resolution imaging on the flipped side of the ore, focusing on identifying mineral texture, color characteristics, impurity distribution, and surface cleanliness. Combining this with previous data, it comprehensively judges the ore quality and outputs sorting instructions to the sorting machine component 600. The two vision systems are optimized for "pre-processing state perception" and "post-flipping quality judgment," respectively, forming the visual foundation for closed-loop intelligent sorting and ensuring the accuracy and stability of barite ore sorting.

[0037] The working principle of the technical solution provided by this invention is as follows: When performing barite ore sorting operations, the ore to be processed is first fed into the feeding mechanism 500 located above the support frame 100. By adjusting the angle between the first inclined plate 5041 and the second inclined plate 5042 in the guide assembly 504, an adjustable figure-eight opening adapted to the current ore particle size is formed, so that the ore falls stably along the free fall trajectory in a single layer and dispersed state under the action of vibration. During the ore's descent, it first passes through a high-speed vision sensor 201, which collects real-time information on surface humidity, dirt levels, and particle size. This information is then transmitted to the control center, which dynamically adjusts the operating parameters of the dynamic hot film mechanism 300 based on this data. The high-pressure vortex fan 307 adjusts its output frequency via a frequency converter, thereby changing the hot air flow rate. Simultaneously, ultrasonic transducers 302 arranged on the upper and lower sides of the hot air cavity 301 inject high-frequency vibration energy into the airflow at a specific angle, forming a hot air curtain carrying ultrasonic energy. When the ore passes through this hot air curtain, the fine dust adhering to its surface due to static electricity or grease is loosened by the ultrasonic cavitation effect. The hot airflow then blows it away along with the water film, achieving efficient dehydration and dust removal. Subsequently, the cleaned ore impacts the rebound plate 404 in the flipping mechanism 400. The rebound plate 404 is composed of multiple parallel wear-resistant rubber strips and has elastic buffering characteristics. While realizing the automatic flipping of the ore and exposing the entire surface, it effectively absorbs the impact force to reduce the risk of breakage. During this process, the impurity particles that are stripped off are blown into the gap of the rebound plate 404 through the air inlet of the power chamber 403, and are introduced into the particle recovery box 407 through the output pipe 406. The particle recovery box 407 is firmly connected to the support frame 100 through the fixing frame. The power pump 408 on its front provides negative pressure airflow to ensure that impurities are continuously transported and temporarily stored in the box.
