Description

Technical Field

[0001] This application relates to the technical field of mineral testing, and in particular to a mineral particle size testing device and measurement method. Background Technology

[0002] A mineral particle size analyzer is a specialized device used to accurately detect the size and distribution of various mineral particles. By analyzing mineral particle size parameters, it provides data support for optimizing mineral processing, controlling metallurgical production, and efficiently utilizing mineral resources.

[0003] Currently, existing mineral particle size detection devices typically include a detection host, a feeding mechanism, a dispersion module, and a particle size analysis module. During use, the operator places the mineral sample to be tested into the feeding mechanism, which then transports the sample to the dispersion module. The operator controls the dispersion module to disperse the mineral sample. The dispersed mineral particles then enter the particle size analysis module, which uses optical or sieving principles to detect the mineral particle size and ultimately outputs mineral particle size distribution data to determine whether the sample meets process requirements.

[0004] When using existing mineral particle size detection devices, the dispersion module often adopts simple stirring or airflow purging methods, which are difficult to effectively disperse mineral samples that are prone to agglomeration. When a large number of undispersed mineral aggregates enter the detection process, the detection results of the particle size analysis module are prone to deviation. Summary of the Invention

[0005] In order to facilitate the dispersion of minerals, this application provides a mineral particle size detection device and measurement method.

[0006] On the one hand, this application provides a mineral particle size detection device, which adopts the following technical solution: A mineral particle size detection device includes a mounting plate, a feeding assembly, a vortex dispersion assembly, a bearing assembly, a driving assembly, and a discharging assembly. The mounting plate is horizontally positioned, and a controller is mounted on its top. A connecting frame is fixedly mounted on the mounting plate, and a first support plate and a second support plate are fixedly mounted on the connecting frame. The first support plate is located below the second support plate, and a CCD camera is mounted on the bottom end of the first support plate. The CCD camera is electrically connected to the controller. A storage box is fixedly mounted on the top of the connecting frame, and the top of the storage box is open. The feeding assembly is located on the second support plate and is used to transfer materials. The material is dispersed at the vortex dispersion component; the vortex dispersion component is located on the first support plate and is used to disperse the material; the bearing component is located on the mounting plate and is used to bear the material dispersed by the vortex dispersion component; the driving component is located on the mounting plate and is used to drive the bearing component to move; the feeding component is located on the mounting plate and is used to collect the material detected by the bearing component, the feeding component includes a vacuum cleaner and a collection bin; the vacuum cleaner is mounted on the mounting plate and is electrically connected to the controller; the collection bin is fixedly mounted on the mounting plate and is connected to the vacuum cleaner through a pipe.

[0007] By adopting the above technical solution, during use, the operator puts the material into the storage bin. After the material is placed in the storage bin, the operator uses the feeding component to transfer the material to the vortex dispersion component. The vortex dispersion component disperses the material, and the driving component drives the carrying component to move, making it easy to evenly place the dispersed material on the carrying component. After the material is placed on the carrying component, the operator takes a picture with a CCD camera, and the picture is transmitted to the controller. The controller processes the image data and calculates the particle size of individual mineral particles. After the material is detected, the operator uses the controller to drive the vacuum cleaner to work. The vacuum cleaner sucks the material on the carrying component into the collection bin, making the equipment easy to detect multiple times. By setting up the vortex dispersion component, the material is easily dispersed.

[0008] Optionally, the feeding assembly includes a vibrating feeder, a support frame, and an intermittent feeding section; the vibrating feeder is mounted on the second support plate and electrically connected to the controller; the storage bin is located above the vibrating feeder and has a discharge port at its bottom; the support frame is fixedly mounted on the second support plate and located on one side of the discharge end of the vibrating feeder, and a guide plate is fixedly mounted on the support frame; the intermittent feeding section is located at the bottom of the storage bin and is used to drive the material in the storage bin to be intermittently fed into the vibrating feeder.

[0009] By adopting the above technical solution, when in use, the operator drives the vibrating feeder to work through the controller. The vibrating feeder drives the material in the storage box to be transferred to the guide plate. The guide plate transfers the material to the vortex dispersion component, so that the material is not easy to accumulate and block at the vortex dispersion component.

[0010] Optionally, the interval feeding section includes an isolation plate, a first motor, and a first reciprocating screw; a sliding groove is provided at the bottom of the storage box, the isolation plate is located at the bottom of the storage box, and a sliding block is fixedly provided on the side near the storage box, the sliding block is located in the sliding groove and is slidably connected to the storage box, and a communicating hole is provided on the isolation plate; the first motor is installed at the bottom of the storage box and is electrically connected to the controller; the first reciprocating screw is rotatably disposed at the bottom of the storage box and is fixedly connected to the output shaft of the first motor, and the first reciprocating screw is threadedly connected to the isolation plate.

[0011] By adopting the above technical solution, during use, the operator drives the first motor to work through the controller. The first motor drives the first reciprocating screw to rotate. The first reciprocating screw drives the partition plate to move back and forth along the length of the first reciprocating screw. When the connecting hole on the partition plate is aligned with the discharge port, the material in the storage box slides into the vibrating feeder through the discharge port and the connecting hole. When the connecting hole on the partition plate is misaligned with the discharge port, the material in the storage box is less likely to slide into the vibrating feeder, making it less likely for the material to accumulate inside the vibrating feeder.

[0012] Optionally, the eddy current dispersion assembly includes a driving block, a material guiding funnel, a driving fan, a feeding pipe, and a mounting box; the driving block is fixedly mounted on the first support plate, a first connecting groove is formed on the top of the driving block, a second connecting groove is formed on one side of the driving block, the second connecting groove is constricted and communicates with the first connecting groove, and a third connecting groove is formed on the side of the driving block away from the second connecting groove, the third connecting groove is constricted and communicates with the first connecting groove; the material guiding funnel is fixedly mounted on the driving block and communicates with the first support plate.

[0013] By adopting the above technical solution, during use, the operator drives the fan to work through the controller, and the fan blows air into the second connecting groove. As the airflow velocity increases and the static pressure decreases when it passes through the narrowing of the second connecting groove, a Venturi effect is formed at the drive block. The material in the guide funnel is transferred to the mounting box. The vortex guide plates arranged in a vortex pattern in the mounting box cause the material to form a vortex motion during the conveying process. The vortex shear force breaks up the agglomerated particles, realizes the dispersion of the material, and makes it difficult for the material to accumulate at the bearing component.

[0014] Optionally, the bearing assembly includes a displacement plate and a bearing plate; the displacement plate is slidably disposed on the mounting plate; the bearing plate is horizontally disposed on the displacement plate and slidably connected to the displacement plate; the CCD camera is used to photograph the material on the bearing plate; the driving assembly includes a first driving part and a second driving part; the first driving part is located on the mounting plate and is used to drive the displacement plate to slide; the second driving part is located on the displacement plate and is used to drive the bearing plate to slide.

[0015] By adopting the above technical solution, when in use, the operator drives the drive component to work. The first drive unit drives the displacement plate to slide, and the displacement plate drives the second drive unit and the bearing plate to slide synchronously. The second drive unit drives the bearing plate to slide, and the bearing plate achieves multi-directional displacement in the longitudinal and transverse directions on the horizontal plane, so that the dispersed material is easy to spread evenly on the bearing plate and the material is not easy to accumulate on the bearing plate.

[0016] Optionally, the first drive unit includes a first support plate, a second support plate, a second motor, a second reciprocating screw, and a guide rod; the first support plate is fixedly disposed on one side of the mounting plate; the second support plate is fixedly disposed on the side of the mounting plate away from the first support plate; the second motor is mounted on the first support plate and electrically connected to the controller; the second reciprocating screw is rotatably disposed between the first support plate and the second support plate and is fixedly connected to the output shaft of the second motor; the displacement plate is threadedly connected to the second reciprocating screw; the guide rod is fixedly disposed between the first support plate and the second support plate, and the displacement plate is slidably connected to the guide rod.

[0017] By adopting the above technical solution, when in use, the operator drives the second motor to work through the controller, the second motor drives the second reciprocating screw to rotate, and the second reciprocating screw drives the displacement plate to slide along the length direction of the second reciprocating screw, so that the material can be easily and evenly laid on the bearing plate.

[0018] Optionally, the second drive unit includes a third reciprocating screw, a moving block, a limiting spring, and a locking block; a reciprocating motor is embedded in the displacement plate, and the reciprocating motor is electrically connected to the controller; a receiving groove is formed on the displacement plate, the third reciprocating screw is horizontally arranged in the receiving groove and rotatably connected to the displacement plate, and the third reciprocating screw is fixedly connected to the output shaft of the reciprocating motor; the moving block is located in the receiving groove and is slidably connected to the displacement plate, and the moving block is threadedly connected to the third reciprocating screw; a storage groove is formed on the moving block, the limiting spring is located in the storage groove, and one end is fixedly connected to the moving block; the locking block is located in the storage groove and is slidably connected to the moving block, the locking block is fixedly connected to one end of the limiting spring, a locking groove is formed at the bottom end of the bearing plate, and the top of the locking block is located in the locking groove.

[0019] By adopting the above technical solution, when the displacement plate slides to one end of the second reciprocating screw, the operator drives the second motor to stop working through the controller, and at the same time drives the reciprocating motor to work. The reciprocating motor drives the third reciprocating screw to rotate, and the third reciprocating screw drives the moving block to slide along the length direction of the receiving groove. The locking block on the moving block drives the bearing plate to slide synchronously. The bearing plate slides along the length direction of the receiving groove, making it easy for the bearing plate to achieve longitudinal and transverse multi-directional displacement on the horizontal plane, thereby making it easy for the dispersed material to be evenly spread on the bearing plate.

[0020] Optionally, a guide plate is fixedly mounted on the displacement plate, and a guide groove is formed on the guide plate; a reset slider is fixedly mounted on one side of the bearing plate, the reset slider is located in the guide groove and is slidably connected to the guide plate; a reset spring is provided in the guide groove, and the two ends of the reset spring are fixedly connected to the reset slider and the guide plate respectively; the drive assembly further includes an adjustment part; the adjustment part includes a first extrusion telescopic rod, a second extrusion telescopic rod, and an isolation telescopic rod; the first extrusion telescopic rod is horizontally arranged, and its fixed end is embedded in the side of the moving block away from the vacuum cleaner, and the rodless cavity of the first extrusion telescopic rod is filled with liquid; the second extrusion telescopic rod is horizontally arranged, and its fixed end is embedded in the side of the moving block away from the first extrusion telescopic rod, and both the rodless cavity and the rod cavity of the second extrusion telescopic rod are filled with liquid. The body has a rodless cavity of the second extrusion telescopic rod connected to the rodless cavity of the first extrusion telescopic rod via a pipe; a guide slope is provided on one side of the locking block; the isolation telescopic rod is horizontally arranged, with its fixed end embedded in the moving block, and its movable end abutting against the locking block; the rodless cavity of the isolation telescopic rod is filled with liquid and connected to the rod cavity of the second extrusion telescopic rod via a pipe; a clearance groove is provided in the displacement plate; a gear is fixedly provided at one end of the third reciprocating screw, and the gear is located in the clearance groove; two sets of the second drive unit and the adjustment unit are provided, and are respectively located on both sides of the receiving groove; the moving blocks in the two sets of the second drive units are respectively located at both ends of the receiving groove, and the gears in the two sets of the second drive units mesh with each other; two sets of locking grooves are provided, and correspond one-to-one with the two sets of the second drive units.

[0021] By adopting the above technical solution, when one of the moving blocks drives the support plate to slide to the side of the receiving groove away from the vacuum cleaner, the return spring is in a compressed state. The side wall of the receiving groove presses against the first compression telescopic rod on the moving block. The liquid in the rodless chamber of the first compression telescopic rod flows through the pipe to the rodless chamber of the second compression telescopic rod, increasing the volume of the rodless chamber of the second compression telescopic rod. The movable end of the second compression telescopic rod extends, decreasing the volume of the rod-side chamber of the second compression telescopic rod. The liquid in the rod-side chamber of the second compression telescopic rod flows through the pipe to the rodless chamber of the isolation telescopic rod, increasing the volume of the rodless chamber of the isolation telescopic rod. The movable end of the telescopic rod extends, causing the locking block to slide into the storage slot. The limiting spring is in a compressed state, while the movable end of the other set of telescopic rods is in a retracted state, and the locking block of the other set abuts against the bottom end of the support plate. When the locking block in one of the second drive units slides into the storage slot, the return spring resets. The return spring drives the support plate to slide closer to the vacuum cleaner through the return slider. When the support plate slides until the locking slot on the support plate is aligned with the locking block, the limiting spring resets. The limiting spring drives the locking block to slide into the locking slot, making it easier for the other set of second drive units to drive the support plate to continue working.

[0030] In use, the operator places the material into the storage bin 123.

The drive block 31 is fixedly mounted on the first support plate 121 and is rectangular in shape. A first connecting groove 311, which is circular in shape, is formed on the top of the drive block 31.

When the connecting hole 2312 on the partition plate 231 is misaligned with the discharge port 1231, the material in the storage bin 123 is less likely to slide into the vibrating feeder 21. Simultaneously, the operator drives the vibrating feeder 21 via the controller 11, which transfers the material in the storage bin 123 to the guide plate 221, which then transfers the material into the guide funnel 32.

[0039] After the material is transferred to the feed funnel 32, the operator drives the drive fan 33 through the controller 11. The drive fan 33 blows air into the second connecting groove 312. As the airflow velocity increases and the static pressure decreases when it passes through the constriction of the second connecting groove 312, a Venturi effect is formed at the drive block 31. The material in the feed funnel 32 is transferred to the mounting box 35. The vortex guide plate 351 arranged in a vortex pattern in the mounting box 35 causes the material to form a vortex motion during the conveying process.

[0049] Reference Figure 6 and Figure 8The adjustment unit 53 has two sets, each corresponding to one of the two sets of second drive units 52. The adjustment unit 53 includes a first compression telescopic rod 531, a second compression telescopic rod 532, and an isolating telescopic rod 533. The first compression telescopic rod 531 is horizontally positioned, with its fixed end embedded in the side of the moving block 522 away from the vacuum cleaner 61. The rodless cavity of the first compression telescopic rod 531 is filled with liquid. The second compression telescopic rod 532 is horizontally positioned, with its fixed end embedded in the side of the moving block 522 away from the first compression telescopic rod 531. Both the rodless and rod-equipped cavities of the second compression telescopic rod 532 are filled with liquid.

[0050] The isolation telescopic rod 533 is horizontally set, and the fixed end is embedded in the moving block 522. The movable end of the isolation telescopic rod 533 abuts against the guide slope of the locking block 524. The rodless cavity of the isolation telescopic rod 533 is filled with liquid and is connected to the rod cavity of the second compression telescopic rod 532 through a pipe.

[0051] Reference Figure 1 The unloading assembly 6 includes a vacuum cleaner 61 and a receiving bin 62. The vacuum cleaner 61 is mounted on the mounting plate 1 and is electrically connected to the controller 11. The receiving bin 62 is vertically mounted on the mounting plate 1 and is connected to the vacuum cleaner 61 through a pipe. The receiving bin 62 is cylindrical and fixedly connected to the mounting plate 1.

[0052] In use, the operator drives the second motor 513 to work via the controller 11. The second motor 513 drives the second reciprocating screw 514 to rotate, and the second reciprocating screw 514 drives the displacement plate 41 to slide along the length direction of the second reciprocating screw 514. When the displacement plate 41 slides to one end of the second reciprocating screw 514, the operator drives the second motor 513 to stop working via the controller 11, and at the same time drives the reciprocating motor 413 to work. The reciprocating motor 413 drives the third reciprocating screw 521 to rotate, and the third reciprocating screw 521 drives the moving block 522 to slide along the length direction of the receiving groove 411. The locking block 524 on the moving block 522 drives the bearing plate 42 to slide synchronously, and the bearing plate 42 slides along the length direction of the receiving groove 411.

[0053] When the support plate 42 moves to the detection area of ​​the CCD camera 1211, the operator uses the controller 11 to stop the first motor 232, the vibrating feeder 21, the second motor 513, and the reciprocating motor 413. When the first motor 232 stops working, the connecting hole 2312 on the isolation plate 231 is misaligned with the discharge port 1231. The operator uses the controller 11 to drive the CCD camera 1211 to photograph the material on the support plate 42, and the captured image is transmitted to the controller 11, which processes the image data.

[0054] After material detection, the operator uses controller 11 to drive the second motor 513 and reciprocating motor 413 to continue working. When one of the moving blocks 522 abuts against the side wall of the receiving tank 411, the return spring 423 is compressed, and the side wall of the receiving tank 411 presses against the first compression telescopic rod 531 on the moving block 522. The liquid in the rodless chamber of the first compression telescopic rod 531 flows through the pipe to the rodless chamber of the second compression telescopic rod 532, increasing the volume of the rodless chamber of the second compression telescopic rod 532. The movable end of the second compression telescopic rod 532 extends, and the volume of the rod-side chamber of the second compression telescopic rod 532 decreases. The liquid in the rod chamber of the telescopic rod 532 flows through the pipe to the rodless chamber of the isolation telescopic rod 533, increasing the volume of the rodless chamber of the isolation telescopic rod 533. The movable end of the isolation telescopic rod 533 extends, driving the locking block 524 to slide into the receiving groove 5221. The limiting spring 523 is in a compressed state, while the movable end of the other set of isolation telescopic rods 533 is in a retracted state. The locking block 524 of the other set abuts against the bottom end of the bearing plate 42, and the limiting spring 523 is in a compressed state.

[0055] When the locking block 524 in one of the second drive units 52 slides into the receiving slot 5221, the return spring 423 resets, and the return spring 423 drives the support plate 42 to slide closer to the vacuum cleaner 61 via the return slider 422. When the support plate 42 slides until the locking slot 421 on the support plate 42 is aligned with the locking block 524, the limit spring 523 resets, and the limit spring 523 drives the locking block 524 to slide into the locking slot 421. When the support plate 42 resets, the operator drives the vacuum cleaner 61 to work, and the vacuum cleaner 61 sucks the material on the support plate 42 into the receiving hopper 62.

[0056] The implementation principle of the mineral particle size detection device and measurement method in this application embodiment is as follows: In operation, the operator places the material into the storage bin 123. After the material is placed in the storage bin 123, the operator drives the first motor 232 through the controller 11. The first motor 232 drives the first reciprocating screw 233 to rotate, and the first reciprocating screw 233 drives the partition plate 231 to move back and forth along the length of the first reciprocating screw 233. When the connecting hole 2312 on the partition plate 231 is aligned with the discharge port 1231, the material in the storage bin 123 slides into the vibrating feeder 21 through the discharge port 1231 and the connecting hole 2312. When the connecting hole 2312 on the partition plate 231 is misaligned with the discharge port 1231, the material in the storage bin 123 is less likely to slide into the vibrating feeder 21.

[0057] Simultaneously, the operator drives the vibrating feeder 21 through the controller 11. The vibrating feeder 21 drives the material in the storage bin 123 to the guide plate 221, which then transfers the material into the guide funnel 32. After the material is transferred to the guide funnel 32, the operator drives the drive fan 33 through the controller 11. The drive fan 33 blows air into the second connecting groove 312. As the airflow velocity increases and the static pressure decreases when it passes through the constriction of the second connecting groove 312, a Venturi effect is formed at the drive block 31. The material in the guide funnel 32 is transferred to the mounting box 35. The vortex guide plates 351 arranged in a vortex pattern in the mounting box 35 cause the material to form a vortex motion during the conveying process. The vortex shear force breaks up the agglomerated particles, thus dispersing the material.

[0058] When the dispersed material is transferred to the bearing plate 42 through the feed pipe 352, the operator drives the second motor 513 to work through the controller 11. The second motor 513 drives the second reciprocating screw 514 to rotate, and the second reciprocating screw 514 drives the displacement plate 41 to slide along the length direction of the second reciprocating screw 514. When the displacement plate 41 slides to one end of the second reciprocating screw 514, the operator drives the second motor 513 to stop working through the controller 11, and at the same time drives the reciprocating motor 413 to work. The reciprocating motor 413 drives the third reciprocating screw 521 to rotate, and the third reciprocating screw 521 drives the moving block 522 to slide along the length direction of the receiving groove 411. The locking block 524 on the moving block 522 drives the bearing plate 42 to slide synchronously, and the bearing plate 42 slides along the length direction of the receiving groove 411.

[0059] When the support plate 42 moves to the detection area of ​​the CCD camera 1211, the operator uses the controller 11 to stop the first motor 232, the vibrating feeder 21, the second motor 513, and the reciprocating motor 413. When the first motor 232 stops working, the connecting hole 2312 on the isolation plate 231 is misaligned with the discharge port 1231. The operator uses the controller 11 to drive the CCD camera 1211 to photograph the material on the support plate 42, and the photographed image is transmitted to the controller 11, which processes the image data. After the material is detected, the operator drives the vacuum cleaner 61 to work, and the vacuum cleaner 61 sucks the material on the support plate 42 into the collection bin 62.

[0060] This application discloses a method for measuring mineral grain size.

[0061] S1 Material feeding: The operator places the material to be tested into the storage box 123; S2 Interval Transfer: The operator drives the first motor 232 through the controller 11. The first motor 232 drives the baffle plate 231 to move back and forth, and the material slides down intermittently into the vibrating feeder 21. At the same time, the operator drives the vibrating feeder 21 to work, and the vibrating feeder 21 transfers the material that slides down from the discharge port 1231 to the vortex dispersion component 3; S3 Material Dispersion: The operator drives the drive fan 33 through the controller 11. The drive fan 33 blows air into the second connecting groove 312, and a Venturi effect is formed inside the drive block 31. The material is transferred to the mounting box 35 through the feeding pipe 34. The vortex guide plate 351 arranged in a vortex pattern inside the mounting box 35 drives the material to form a vortex motion during the conveying process. The vortex shear force is used to break up the agglomerated particles in the material and achieve material dispersion. S4 Material Placement: The operator drives the bearing plate 42 to move longitudinally and laterally in multiple directions on the horizontal plane through the first drive unit 51 and the second drive unit 52. S5 Material Detection: The operator takes pictures of the material on the support plate 42 through the CCD camera 1211. The captured image is transmitted to the controller 11, which processes the image data and calculates the particle size of individual mineral particles. S6 Material Collection: The operator drives the vacuum cleaner 61 to work through the controller 11, and the vacuum cleaner 61 collects the detected material into the collection bin 62. S7 Cyclic Detection: Repeat steps S1-S6. The controller 11 performs statistical analysis on the particle size data from multiple detections and calculates the particle size distribution of the material.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
