Description

Technical Field

[0001] This utility model belongs to the technical field of ore processing equipment, and in particular relates to an automated online ore particle size detection and grading device. Background Technology

[0002] Mineral particle size analysis is a technique that analyzes and studies the size, morphology, and distribution of particles in mineral samples. In mineralogy, particle size analysis is a crucial technique because it directly relates to the physical, chemical, and processing properties of minerals. Through mineral particle size analysis, we can understand the particle size composition, distribution patterns, and morphological characteristics of minerals, providing important theoretical basis for mineral beneficiation and processing.

[0003] However, during transportation and transfer, the agglomeration and stockpiling of ore can lead to uneven particle distribution, making it impossible to comprehensively and accurately characterize the true particle size composition and morphological characteristics of the mineral sample during subsequent particle size analysis. This affects the reliability and quality of the test results. Specifically, stockpiling or agglomeration may cause local particle distribution to be inconsistent with the overall distribution during testing, causing the analysis results to deviate from reality; particle size analysis relies on uniformly dispersed samples, and agglomeration can mask fine particles or exaggerate the proportion of coarse particles, resulting in distorted particle size distribution data; inaccurate test results may also mislead the design of mineral processing or beneficiation parameters, reducing production efficiency or resource utilization. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automated online ore particle size detection and grading device to solve the problem of uneven particle distribution caused by agglomeration and stockpiling during the transportation and transfer of ore.

[0007] A support assembly, the support assembly including an upper support plate, the upper support plate being movably disposed within the housing;

[0008] A lever assembly, comprising a lever and a floating rod, wherein the lever is mounted on the floating rod, and the floating rod is vertically mounted on the support assembly via a floating assembly, wherein when the floating rod drives the lever to rotate, the distance between the lower edge of the lever and the upper end face of the upper support plate changes in a gradient.

[0009] An industrial camera, wherein the industrial camera is disposed inside the housing.

[0010] In one embodiment of the present invention, the support assembly further includes a lower support plate, which is installed inside the housing and elastically connected to the upper support plate.

[0011] In one embodiment of the present invention, the supporting assembly further includes a collar, and a linear actuator is provided between the upper supporting plate and the lower supporting plate. The linear actuator drives the upper supporting plate to tilt to achieve unloading.

[0012] In one embodiment of this utility model, at least one vibration motor is provided on the bottom surface of the upper support plate.

[0013] In one embodiment of the present invention, the floating component includes a sleeve, a limiting block, and a wheel-shaped block. The sleeve is fixedly installed in the middle of the supporting component, the limiting block is disposed at one end of the sleeve, the wheel-shaped block is fixedly installed on the floating rod, and the sleeve is sleeved on one end of the floating rod. The floating rod rotates and drives the wheel-shaped block and the limiting block to roll into contact.

[0014] In one embodiment of the present invention, the upper end surface of the limiting block is provided with a circumferential stepped surface, and the adjacent planes of the stepped surface are transitioned by an arc-shaped surface.

[0015] In one embodiment of this utility model, the floating rod is inserted into one end of the sleeve and connected to the output shaft of the drive motor via a telescopic shaft, and the other end of the floating rod is equipped with the lever plate.

[0019] This utility model includes at least the following beneficial technical effects:

[0020] This invention proposes an automated online particle size detection and grading device for ores. First, a floating rod drives a rotating plate, causing a gradient change in the distance between the lower edge of the plate and the upper surface of the upper support plate during rotation. This actively disperses the aggregated ore stockpile and ensures uniform particle dispersion, avoiding detection deviations caused by inconsistencies between local and overall distribution, improving sample representativeness, and solving the problem of uneven particle distribution. Second, an industrial camera directly photographs the dispersed particles. Combined with the gradient design (different spacing adjusts the distribution of particles of different sizes), it can simultaneously capture the distribution of coarse and fine particles, avoiding the problem of fine particles being masked or the proportion of coarse particles being distorted. This makes the particle size data closer to the true value, improving detection accuracy and reliability. Attached Figure Description

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] Please see Figures 1-6 As shown, this utility model proposes an automated online ore particle size detection and grading device, including a housing 200, a support assembly 203, a deflector assembly, and an industrial camera 300. The housing 200 is provided with an inlet 201 and an outlet 202. The support assembly 203 includes an upper support plate 2031, which is movably disposed within the housing 200. The deflector assembly includes a deflector 204 and a floating rod 205. The deflector 204 is mounted on the floating rod 205, which is vertically mounted on the support assembly 203 via a floating assembly. The floating rod 205 drives the deflector 204 to rotate, and the distance between the lower edge of the deflector 204 and the upper end face of the deflector 204 varies in a gradient. The industrial camera 300 is disposed inside the housing 200.

[0033] In this embodiment, iron ore fed into the housing 200 through the feed inlet 201 is spread onto the upper support plate 2031 by the guide plate 204. Simultaneously, as the guide plate 204 rotates, the distance between it and the upper surface of the upper support plate 2031 increases periodically (i.e., the distance between the lower edge of the guide plate 204 and the upper surface of the guide plate 204 lies on different gradient planes). This not only allows the agglomerated and piled iron ore to be spread out evenly but also completes the grading of the iron ore. Meanwhile, the industrial camera 300 can be located at the inner top of the housing 200. The industrial camera 300 acquires image data of the ore spread on the upper support plate 2031, then analyzes the image data and processes it to obtain various detection data of the ore (such as defect area, particle size, etc.). The detection data are then summarized to analyze the overall ore quality and performance.

[0034] In one embodiment of the present invention, the support assembly 203 further includes a lower support plate 2032, which is installed inside the housing 200 and is elastically connected to the upper support plate 2031.

[0035] It should be noted that the housing 200 can be a cylindrical housing. The lower support plate 2023 can be coaxially rotatably installed inside the housing 200 via a motor. An elastic element 2033 can be provided between the lower support plate 2032 and the upper support plate 2031 to achieve an elastic connection. The elastic element 2033 can be a spring or an elastic telescopic column, etc. The lower support plate 2032 is used to support the weight of the upper support plate 2031.

[0036] In one embodiment of the present invention, a linear actuator 20313 is provided between the upper support plate 2031 and the lower support plate 2032. The linear actuator 20313 drives the upper support plate 2031 to tilt to achieve unloading.

[0037] It should be noted that the linear actuator 20313 can be one of a cylinder assembly, a hydraulic cylinder assembly, or an electric telescopic rod. After the iron ore is tested and graded, the linear actuator 20313 can drive the upper support plate 2031 to tilt and discharge material into the discharge port 202, thereby realizing the angle adjustment and discharge functions of the upper support plate 2031.

[0038] In one embodiment of the present invention, at least one vibration motor 2034 is provided on the bottom surface of the upper support plate 2031.

[0039] It should be noted that after the iron ore raw material is transported to the upper support plate 2031, the upper support plate 2031 can be driven to vibrate by the vibration motor 2034 to perform initial spreading of the iron ore, so as to avoid the situation of large stockpiling or agglomeration areas, and facilitate the subsequent further dispersal of the stockpile by the push plate 204 and the application of pressure to achieve a flat spreading effect.

[0040] In one embodiment of the present invention, the floating component includes a sleeve 206, a limiting block 207, and a wheel-shaped block 2082. The sleeve 206 is fixedly installed in the middle of the supporting component 203, the limiting block 207 is disposed at one end of the sleeve 206, the wheel-shaped block 2082 is fixedly installed on the floating rod 205, and the sleeve 206 is sleeved on one end of the floating rod 205. The floating rod 205 rotates and drives the wheel-shaped block 2082 and the limiting block 207 to roll into contact.

[0041] It should be noted that a support rod 2081 is provided on the central axis of the wheel block 2082. The support rod 2081 is arranged horizontally, and one end of it is fixedly connected to the floating rod 205, thereby realizing the connection between the wheel block 2082 and the floating rod 205. When the wheel block 2082 rotates with the rotation of the floating rod 205, the rim of the wheel block 2082 rolls on the upper surface of the limiting block 207.

[0042] Furthermore, the upper surface of the limiting block 207 is provided with a circumferential stepped surface, and the adjacent planes 2071 of the stepped surface are connected by an arc-shaped surface 2072.

[0043] It should be noted that during the rotation of the floating rod 205, it drives the dial plate 204 and the wheel block 2082 to move synchronously. The wheel block 2082 rolls on the upper end face of the limiting block 207. As the floating rod 205 continues to rotate, the height of the wheel block 2082 on the limiting block 207 can gradually increase. That is, the distance between the lower edge of the dial plate 204 and the upper end face of the upper support plate 2031 gradually increases, so that the graded iron ore transitions from small particle size to large particle size. During the process, the floating rod 205 rotates relative to the sleeve 206.

[0044] Furthermore, the limiting block 207 has a hollow annular columnar structure, and its outer and inner diameters are the same as those of the sleeve 206. The top of the limiting block 207 has at least two gradient-arranged planes 2071, connected by an arc-shaped surface 2072. As the lever 204 rotates, it drives the wheel-shaped block 2082 to move a certain distance along the plane. During this process, combined with the distance between the lower edge of the lever 204 and the upper end face of the upper support plate 2031, iron ore of this particle size is separated. As the lever 204 continues to rotate, the wheel-shaped block 2082 transitions from the arc-shaped surface 2072 to a plane 2071 of another height, increasing the distance and further separating the next particle size of iron ore. This process continues to complete the iron ore spreading and grading operation.

[0045] In one embodiment of this utility model, one end of the floating rod 205 is inserted into the sleeve 206 and connected to the output shaft of the drive motor 2052 via the telescopic shaft 2051, and the other end of the floating rod 205 is equipped with a dial plate 204.

[0046] In one embodiment of the present invention, the dial assembly further includes an adjustment plate 2042, which is inserted into the dial 204, and the lower edge of the adjustment plate 2042 extends parallel to the lower edge of the dial 204.

[0047] It should be noted that the dial plate 204 may have a groove 2041, and the adjusting plate 2042 is installed in the groove 2041 by a locking bolt. When adjustment is required, loosen the locking bolt, slide the adjusting plate 2042 to the appropriate position, and then tighten the locking bolt.

[0048] In one embodiment of the present invention, the upper support plate 2031 is a split type and includes a collar 20311 and at least two sub-plates 20312. Each sub-plate 20312 and the corresponding lower support plate 2032 are provided with a linear stroke actuator 20313.

[0049] It should be noted that the collar 20311 contains at least two dividing plates 20312. Each dividing plate 20312 is driven by an independent linear actuator 20313 to tilt and align with the discharge port 202, thereby achieving angle adjustment and discharge functions. At this time, the collar 20311 can slide in contact with the inner wall of the housing 200, and the dividing plates 20312 can be connected to the collar 20311 via hinges. After the iron ore is tested and graded, the dividing plates 20312 can be sequentially driven to tilt and align with the discharge port 202 for discharge.

[0050] In one embodiment of this utility model, a conveying mechanism 100 is further included. The discharge end of the conveying mechanism 100 corresponds to the inlet 201 of the housing 200, and a distribution plate 1001 is provided at the discharge end. The discharge outlet 202 of the housing 200 is located on the guide plate 209. The distribution plate 1001 is used to alternately convey iron ore into different housings for detection and grading (the distribution plate 1001 can be Y-shaped or fan-shaped, with its two outlets corresponding to two detection housings 200 respectively, and the motor is controlled by a PLC to rotate periodically, realizing the periodic switching of the ore flow channel), which can improve the efficiency of iron ore detection and grading. The distribution plate 1001 can be controlled to rotate by a motor or a rotary cylinder. When the detected and graded iron ore is output, the guide plate 209 facilitates the collection of the iron ore.

[0051] This utility model proposes an automated online particle size detection and grading device for ore. When iron ore raw material is conveyed to the upper support plate 2031, the upper support plate 2031 is first driven to vibrate by the vibration motor 2034 to perform initial spreading of the iron ore, avoiding excessive stockpiling or agglomeration. With the rotation of the guide plate 204, the guide plate 204 further disperses the stockpiled material and achieves a flat spreading effect by applying pressure. Specifically, based on the distance between the lower edge of the guide plate 204 and the upper end face of the upper support plate 2031, iron ore of this particle size is sorted out. As the guide plate 204 continues to rotate, the wheel-shaped block 2082 transitions from the arc surface 2072 to a plane 2071 of another height, increasing the distance (i.e., the distance between the lower edge of the guide plate 204 and the upper end face of the guide plate 204 is on different gradient planes), thereby sorting out the next particle size of iron ore. This process continues to complete the spreading and grading of the iron ore. Meanwhile, the industrial camera 300 can directly photograph the dispersed particles. Combined with a gradient design (adjusting the distribution of particles of different sizes at different intervals), it can capture the distribution of coarse and fine particles. Therefore, this invention solves the problem of uneven particle distribution caused by agglomeration and stockpiling during ore transportation and transfer. It makes ore particle size data closer to the true value, improving the accuracy and reliability of grading and detection.
