Description

Technical Field

[0001] This disclosure relates to the field of material sorting, specifically to a jet force detection device. Background Technology

[0002] In some material sorting scenarios, intelligent dry separators for mining can perform material sorting with high efficiency. High-pressure airflow is controlled by solenoid valves to deliver gas to nozzles for spraying. However, the lack of measured data on the spraying force of different nozzles and solenoid valve models under complex mining conditions means that design and selection rely on experience, making it difficult to guarantee sorting accuracy. Furthermore, the lack of time-period test data for the spraying force used in intelligent dry separators makes it impossible to accurately match the mineral's falling speed with the sorting rhythm, thus limiting the improvement of equipment performance.

[0021] To overcome the problems existing in related technologies, an exemplary embodiment of this disclosure provides a jetting force detection device 100, such as... Figure 1 , Figure 2 As shown, it includes: a first mounting platform 110, a second mounting platform 120, an exhaust device 130, a sensor assembly 140, and a drive device (not shown in the figure).

[0022] Second installation platform 120, such as Figure 1 , Figure 2As shown, the first mounting platform 110 and the second mounting platform 120 can be arranged opposite to the first mounting platform 110. The first mounting platform 110 and the second mounting platform 120 can be used to install the sensor assembly 140 or the exhaust device 130, respectively. The first mounting platform 110 and the second mounting platform 120 can each have a platform surface, and the platform surfaces of the two are arranged opposite to each other. The exhaust device 130 can be installed on the platform surface of the first mounting platform 110 and the sensor assembly 140 can be installed on the platform surface of the second mounting platform 120 by bolts or the like, so that the sensor assembly 140 and the exhaust device 130 are arranged opposite to each other. In some other embodiments, the first mounting platform 110 and the second mounting platform 120 may not have a complete platform surface. For example, they can be frame structures, used to install the exhaust device 130 and the sensor assembly 140, respectively. The first mounting platform 110 and the second mounting platform 120 only need to be able to install the exhaust device 130 and the sensor assembly 140 respectively and be arranged opposite to each other. In some embodiments, the first mounting platform 110 and the second mounting platform 120 can be arranged vertically along the direction of gravity. For example, the first mounting platform 110 can be positioned above or below the second mounting platform 120. Vertical arrangement facilitates detection using tension-pressure gravity sensors and the like, improving detection accuracy. In other embodiments, the first mounting platform 110 and the second mounting platform 120 can also be arranged laterally along the horizontal direction. The first mounting platform 110 or the second mounting platform 120, in cooperation with a driving device, can detect the blowing force at different distances, providing support for obtaining data on the variation of blowing force with distance.

[0023] Exhaust device 130, such as Figure 1 , Figure 2 As shown, the exhaust device 130 can be installed on the first mounting platform 110 and has a gas outlet facing the second mounting platform 120 for discharging gas towards the second mounting platform 120. The exhaust device 130 may have an internal air passage structure to ensure stable airflow output. The front end of the exhaust device 130 may have a gas outlet; the shape and size of the outlet can be customized according to testing requirements, such as circular or flat, to simulate different blowing patterns. In some embodiments, the exhaust device 130 may be equipped with a solenoid valve. Different models and types of solenoid valves can be replaced, and the gas can be quickly opened and closed via electromagnetic control. Combined with a precision valve core structure, this ensures the accuracy of the airflow injection. Simultaneously, a pressure regulating component can be equipped to adjust the output gas pressure in real time to meet the requirements of different testing conditions. In some embodiments, the exhaust device 130 may be equipped with nozzles for discharging gas. One or more nozzles may be provided, and multiple nozzles can be arranged in different combinations.

[0024] Sensor assembly 140, such as Figure 1 , Figure 2As shown, it can be installed on the second mounting platform 120 and can be used to detect the blowing force of the gas discharged from the exhaust device 130. The sensor assembly 140 can detect the blowing force through a mechanical sensor such as a pressure sensor or a tension / weight sensor. The sensor assembly 140 can be rigidly connected to the second mounting platform 120 by bolts and locating pins, which can ensure that the installation position is fixed and accurate, and avoid positional displacement caused by airflow impact.

[0025] In some embodiments, such as Figure 1 As shown, the first mounting platform 110 can be positioned below the second mounting platform 120, and the exhaust device 130 is positioned above the first mounting platform 110. It can be fixedly connected to the first mounting platform 110 using bolts or similar means to ensure stable installation and easy disassembly and replacement. The sensor assembly 140 can be positioned below the second mounting platform 120, opposite the exhaust device 130, and can use a tension-weight sensor to detect the blowing force of the gas discharged from the exhaust device. The exhaust device 130 can be connected to an external air source 150 via a high-pressure air hose quick connector, enabling convenient access and disconnection of the air source 150. By replacing different models of solenoid valve assemblies or different types of nozzles, the exhaust device 130 can simulate blowing conditions under different working conditions, achieving multi-dimensional detection of the blowing force. Simultaneously, in conjunction with the control system, it achieves automated blowing, precisely controlling the blowing time and frequency. The diverse adjustment and adaptation functions can meet the testing needs of different types of solenoid valves and complex working conditions, improving the versatility and adaptability of the blowing force detection device 100.

[0026] The driving device can be connected to either the first mounting platform 110 or the second mounting platform 120, or both. It is used to adjust the distance between the first mounting platform 110 and the second mounting platform 120, so that the sensor assembly 140 can detect the blowing force at different distances. The driving device can be driven by a cylinder or similar means. For example, the driving device may include a cylinder positioned below the first mounting platform 110, and the lifting and lowering of the cylinder controls the lifting and lowering of the first mounting platform 110, thereby changing the distance between the second mounting platform 120 positioned above the first mounting platform 110. In other embodiments, the driving device may also include a slider, a guide rail, or a lead screw and nut adjustment device, which can be connected to either the first mounting platform 110 or the second mounting platform 120, or simultaneously to both. The drive unit can be rigidly connected to the first mounting platform 110 or the second mounting platform 120 via a slider or guide rail. The slider can be embedded in the groove of the linear guide rail and fixed to the bottom of the first mounting platform 110 or the top of the second mounting platform 120 by high-strength bolts. This allows the first mounting platform 110 and the second mounting platform 120 to move towards each other. Alternatively, it can be securely connected to either the first mounting platform 110 or the second mounting platform 120 via a lead screw and nut adjusting device. Rotating the nut sleeve allows the first mounting platform 110 and the second mounting platform 120 to move towards each other. Furthermore, it can be connected via a motor to ensure the stability of power transmission.

[0027] In this embodiment, the jet force detection device 100 can adjust the distance between the first mounting platform 110 and the second mounting platform 120 through the drive device, which can simulate the working conditions of the exhaust device 130 and mineral particles at different distances in the actual operation of the sorting machine, and solve the problem of single data in traditional fixed distance detection; the sensor component 140 can measure the value of the jet force of the exhaust device with high accuracy, which can simplify the operation process, further reduce human error, and meet the needs of various exhaust devices 130. The nozzle model of the exhaust device 130 can be changed, the number of nozzles can be increased, and the model of the solenoid valve can also be changed, which can meet diverse detection needs, improve data reliability, provide experimental support for the sorting machine system, solve the problem of no actual accurate data of jet force, and help improve the sorting accuracy of the sorting machine.

[0028] In some embodiments, such as Figure 1 , Figure 2 As shown, the sensor assembly 140 may include a sensor 141 and a force plate 142.

[0029] Sensor 141, such as Figure 1 , Figure 2As shown, the force plate 142 can be fixedly installed on the side of the second mounting platform 120 facing the first mounting platform 110. The force plate 142 can be fixedly connected to the sensor 141, and the force plate 142 can face the exhaust device 130. It is used to squeeze the sensor 141 when subjected to the blowing force of the gas discharged from the exhaust device 130, so that the sensor 141 can detect the blowing force of the discharged gas. The sensor 141 can be a pressure sensor or a tension-weight sensor, etc. The force plate 142 can be circular, rectangular, triangular, or irregular in shape to simulate the force surface of materials in actual sorting. In some embodiments, the second mounting platform 120 can be disposed above the first mounting platform 110, the tension-weight sensor can be fixed on the second mounting platform 120, and the force plate 142 can be disposed below the tension-weight sensor. The force plate 142 can face the gas ejected from the exhaust device 130, and the tension-weight sensor can be squeezed by the force plate 142 to detect the force value of the force plate 142. The jetting force of the exhaust device 130 can convert the physical pressure signal of the force plate 142 into an electrical signal and transmit it to the data processing system. The data processing system can be a computer or the like, and can be equipped with a jetting force receiving module to receive the force data of the force plate 142.

[0030] In this embodiment of the disclosure, the sensor assembly 140 is equipped with a sensor 141 and a force plate 142. The sensor 141 can accurately receive the force value when the force plate 142 is squeezed, with high detection accuracy and accurate test data. This provides experimental support for the sorting machine system, facilitates subsequent test modifications, enables efficient testing, and improves the accuracy of subsequent sorting equipment.

[0031] In some embodiments, the distance between the force plate 142 and the gas outlet can be 1-150 mm. The force plate 142 can serve as a component that directly bears the impact of the jetting airflow. When the distance between the force plate 142 and the gas outlet is 1 mm, 5 mm, or other relatively close distances, it can simulate the situation of material being jetted at close range by the sorting equipment. When the distance between the force plate 142 and the gas outlet is 100 mm, 12 mm, 150 mm, or other relatively far distances, it can simulate the situation of material being jetted at long distance by the sorting equipment. The distance between the force plate 142 and the gas outlet can also be 80 mm. A moderate distance between the gas outlet and the force plate 142 can simulate the jetting of most materials. In this embodiment, the distance between the force-bearing plate 142 and the gas outlet is set to 1-150mm, which can cover the blowing of the jet gas from near to far distance. This can simulate the distance changes between the blowing source and the material in different industrial scenarios such as mining dry separators. It avoids the limitations of fixed-distance detection and the measurement of a single index, providing a large amount of data for equipment setup, reducing measurement errors, and solving the problem of lacking accurate actual data on the blowing force.

[0032] In this embodiment, the distance between the first mounting platform 110 and the second mounting platform 120 can be adjusted using a driving device, thereby allowing the distance between the force-bearing plate 142 and the gas outlet to be adjusted within the range of 1mm-150mm, and the magnitude of the blowing force under different conditions can be detected. Furthermore, after each adjustment distance, the blowing force can be continuously recorded for a period of time by turning on the exhaust device 130 for a period of time and then turning it off, including the initial stage of airflow (blowing force increases from zero to present, from small to large), the middle stage of airflow (blowing force is basically stable), and the final stage of airflow (blowing force decreases from large to small, from present to absent). This allows for better detection of the blowing force at different distances and stages.

[0033] In some embodiments, the width of the force plate 142 facing the exhaust device 130 can be 5-300mm. When the force plate 142 is circular, its width can be the diameter of the circle; when the force plate 142 is rectangular, its width can be the length of any side of the rectangle. When the width of the force plate 142 facing the exhaust device 130 is 5mm, 10mm, etc., it can simulate the blowing of small-particle materials. When the width of the force plate 142 facing the exhaust device 130 is 200mm, 300mm, etc., it can simulate the blowing of large materials. In this embodiment, setting the width of the force plate 142 facing the exhaust device 130 can cover the full range of materials to be blown, from small pieces to large pieces. This avoids the limitations of a fixed material width, provides more comprehensive data for the setting of the blowing equipment, reduces errors, avoids the measurement of a single index, has high detection accuracy, and provides precise experimental data, thus providing experimental support for the sorting machine system.

[0034] In some embodiments, the force plate 142 is detachably connected to the sensor 141, allowing for the replacement of force plates 142 with different areas. In this embodiment, the force plate 142 can be detachably connected to the sensor 141, for example, by bolts or snap-fit ​​connections. A standardized interface plate can be provided at the bottom of the force plate 142, which can match the corresponding screw holes on the top of the sensor 141, enabling quick assembly and disassembly of the force plate 142. The jetting force detection device can be equipped with multiple force plates 142 of different areas and shapes. By replacing force plates 142 of different areas and shapes, the area of ​​the force plate 142 can be changed to simulate different materials.

[0035] In other embodiments, the force-bearing plate 142 is configured such that the area facing the exhaust device 130 is adjustable. For example, the force-bearing plate 142 adopts a split-type splicing structure, consisting of a central base plate and four expandable wing plates. When the area needs to be expanded, the four expandable wing plates of the force-bearing plate 142 can be unfolded; when the area needs to be reduced, the four expandable wing plates of the force-bearing plate 142 can be folded. As another example, the force-bearing plate 142 can be composed of two hinged plates; when the area needs to be expanded, one plate folds downward and is fixed; when the area needs to be reduced, the other plate unfolds upward and is fixed. Yet another example is that the force-bearing plate 142 can be composed of two slidably connected plates, such as a slider connection or a guide rail connection; when the area needs to be expanded, one plate can slide out and be fixed; when the area needs to be reduced, the other plate can slide back and be fixed. This allows for effective adjustment of the force-bearing area of ​​the force-bearing plate 142.

[0036] In this embodiment, the area of ​​the force plate 142 facing the exhaust device 130 can be adjusted. The area of ​​the force plate 142 can be directly replaced or adjusted, which can cover the full range of materials to be sprayed, from small pieces to large pieces. The adjustment method is flexible, the operation is simple, and it is easy to adjust. It can provide more comprehensive data for the setting of the spraying equipment, with high detection accuracy, accurate test data, and rich measurement data, providing good data support.

[0037] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the jet force detection device 100 may further include a distance sensor 160, which can be mounted on the first mounting platform 110 or the second mounting platform 120, for detecting the distance between the gas outlet and the force plate 142. The distance sensor 160 can be fixedly connected to the first mounting platform 110 or the second mounting platform 120, and installed by means of bolt fixing or clip fixing. The distance sensor 160 can be connected to the data processing system via a data cable to achieve precise displacement control and feedback. The drive device can achieve precise adjustment of the distance between the first mounting platform 110 and the second mounting platform 120. The distance sensor 160 can measure the distance between the gas outlet of the exhaust device 130 and the force plate 142 in real time, which can meet the distance testing requirements under different working conditions. Through the closed-loop control system, the distance can be automatically adjusted according to the set parameters and the displacement data can be fed back in real time, which can ensure the accuracy of the test distance. It can support linkage control with the sensor assembly 140 and the exhaust device 130, for example, automatically triggering jet force detection after adjusting the distance, improving the degree of automation of the test.

[0038] In this embodiment, the blowing force detection device 100 can be equipped with a distance sensor 160, which can be installed on the first mounting platform 110 or the second mounting platform 120, and can measure the distance between the gas outlet of the exhaust device 130 and the force plate 142 in real time. Compared with traditional manual measurement, it can eliminate human error, and has higher accuracy, with a measurement error of only ±0.1mm. It can be used in conjunction with a drive device to achieve automatic spacing adjustment, automatic step-by-step detection according to a set program, and synchronous recording of distance and blowing force data, improving efficiency and accuracy, and providing a large amount of data support for the sorting equipment.

[0039] In some embodiments, such as Figure 1 , Figure 2 As shown, the jet force detection device 100 may further include a displacement platform 170, which can be arranged opposite to the distance sensor 160. The distance between the displacement platform 170 and the distance sensor 160 is the same as the distance between the gas outlet and the force plate 142. The displacement platform 170's arrangement opposite to the distance sensor 160 and its matching distance with the gas outlet and the force plate 142 allow for precise spatial positioning. The displacement platform 170 can be mounted on the first mounting platform 110 and can be connected by bolts or clips. In this embodiment, the displacement platform 170 acts as a target, dynamically simulating actual working conditions: by precisely replicating the distance between the gas outlet and the force plate 142, and coordinating with the drive device to adjust the positions of the first mounting platform 110 and the second mounting platform 120, multi-dimensional jet force detection can be achieved. For example, in the testing of dry separators for mining, the changes in blowing force experienced by mineral particles at different distances can be simulated, providing reliable data support for equipment design optimization and effectively solving the problems of incomplete and poor repeatability of previous test data.

[0040] In some embodiments, such as Figure 1 , Figure 2 As shown, the exhaust device 130 may include: one or more exhaust ports 131 and a gas passage 132.

[0041] One or more air outlets 131, such as Figure 1 , Figure 2As shown, the exhaust device 130 can be used to install nozzles to form a gas outlet; the gas passage 132 can be connected to the gas outlet 131 and can be used to connect to the gas source 150. The main body of the exhaust device 130 can be cast from high-strength aluminum alloy or stainless steel. The internal gas passage 132 can form a streamlined pipe structure to reduce gas flow resistance and ensure stable airflow. One or more gas outlets 131 can be provided. One end of the gas passage 132 can be quickly connected to the external gas source 150 through a standard threaded interface or flange; the other end can be connected to the gas outlet 131. Each gas outlet can be equipped with a nozzle mounting interface to adapt to different types of nozzles, which can be quickly installed by threading or snap-fitting. The exhaust device 130 can be fixed to the first mounting platform 110 with high-strength bolts to ensure the stability of the device during operation. The gas passage 132 can also be provided with a structure for installing solenoid valves, facilitating the installation of different models of solenoid valves in the gas passage 132, thereby facilitating the testing of the blowing status of different models of solenoid valves. In this embodiment, one or more air outlets 131 and gas passages 132 are provided. Different specifications of nozzles or different models of solenoid valves can be replaced. Multiple sets of different nozzle parameters can be tested simultaneously, which facilitates gas ejection. It can be connected to a gas source 150 to adjust the gas pressure of the gas passage 132. It can simulate the blowing conditions in various industrial scenarios such as dry mineral separators, providing reliable data for nozzle selection and layout optimization of the separator. The modular structure reduces equipment maintenance costs and effectively improves equipment utilization.

[0042] In some embodiments, such as Figure 1 , Figure 2 As shown, the jet force detection device 100 may further include: a nozzle 180, such as Figure 1 , Figure 2 As shown, nozzle 180 can be connected to the outlet of exhaust device 130 to form a gas outlet. The nozzle 180 is provided on exhaust device 130 to facilitate the detection of the blowing status of different types of solenoid valves. Different distances can also be adjusted via a drive device to obtain corresponding detection data.

[0043] In other embodiments, such as Figure 1 , Figure 2 As shown, the jet force detection device 100 may further include: a solenoid valve 190, which can be connected to a gas passage to control gas discharge from the gas outlet. When the solenoid valve 190 is fixed, the type of nozzle 180 can be changed. The nozzle 180 is connected to the gas outlet and can be quickly connected to the gas outlet 131 of the exhaust device 130. The nozzle type can be various styles such as circular direct injection, fan-shaped diffusion, or multi-hole diversion, and the nozzle diameter can be 1-20mm to adapt to different detection needs. It can form a gas outlet and can be used for gas jetting.

[0044] In this embodiment, both the nozzle 180 and the solenoid valve 190 can adopt standardized interfaces, allowing for quick replacement of different models of components to meet diverse testing needs. Test data from different nozzles 180 and solenoid valves 190 can be obtained. In the development of mining equipment, by utilizing combinations of different nozzles 180 and the control of the solenoid valve 190, a suitable blowing scheme can be quickly tested, reducing maintenance costs, extending the service life of the blowing force detection device 100, and ensuring the sorting accuracy and output of the sorting equipment.

[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, the exhaust device 130 may include multiple air outlets 131, which can be arranged side-by-side or in a matrix. The air outlets 131 can employ standardized threaded interfaces or quick-release snap-fit ​​designs, allowing for the rapid installation of nozzles of different specifications, adapting to various spray patterns such as circular and fan-shaped sprays. There can be eight or more air outlets. Multiple air outlets 131 can be arranged side-by-side. Multiple air outlets can be arranged sequentially along a straight line, forming a single-row linear structure, with uniform spacing between adjacent air outlets, such as 10mm, 20mm, 50mm, or 100mm. Alternatively, they can be arranged in a matrix, with the air outlets 131 distributed in rows and columns, forming a 2x4 or 3x5 matrix, creating a two-dimensional planar layout. The row and column spacing can be customized, such as 20mm or 30mm. In this embodiment of the disclosure, by arranging multiple air outlets 131 side by side or in a matrix, it is possible to simulate large-area coverage blowing conditions, such as multi-nozzle collaborative sorting in a mining dry separator. Both arrangement methods adopt a standardized interface design, which can support quick layout switching, adapt to different blowing force detection requirements, efficiently simulate actual working conditions, optimize equipment blowing schemes, and measure a large amount of test data for use in the sorting equipment.

[0046] In some embodiments of this disclosure, a control module may be provided, such as... Figure 2 , Figure 3As shown, the control module may include: a computer 210, a jet force signal module 220, a distance signal module 230, and a signal module 240 for transmitting signals to the solenoid valve. First, the distance between the first mounting platform 110 and the second mounting platform 120 can be manually adjusted, transmitting information to the distance signal module 230. Next, the computer 210 receives distance information from the distance sensor. Based on distance commands, the computer 210 can further adjust the distance between the first mounting platform 110 and the second mounting platform 120. At this time, the solenoid valve signal module 240 can open the solenoid valve 190, allowing the exhaust device 130 to spray gas onto the sensor assembly 140. The force plate 142 of the sensor assembly 140 can compress the tension-weight sensor, which transmits information to the jet force signal receiving module 220 and records it in the computer 210. The computer 210 can then transmit information to the solenoid valve signal module 240 to stop the exhaust, controlling the exhaust device 130 to stop exhausting. Within a specific time period, the computer 210 can record data on different jet forces at the same distance throughout the entire time period. Different time periods can be set, and the distance between the first mounting platform 110 and the second mounting platform 120 can vary within each time period. Therefore, data on different blowing forces at different time periods under different distance conditions can be obtained.
