Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for ore sample preparation, and specifically discloses an integrated device for molybdenum concentrate sample preparation, sorting, and weighing. Background Technology

[0002] Molybdenum concentrate is mainly composed of MoS2, is lead-gray in color, similar to graphite, and has a metallic luster. It belongs to the hexagonal series, and its crystals are often hexagonal platy, with patterns on the base. It is soft, slippery, and thin, flexible. Molybdenum concentrate can be used to produce ferromolybdenum alloys, metallic molybdenum, calcium molybdate, ammonium molybdate, lubricants, etc.

[0003] Molybdenum concentrate is commonly found in the contact zone between granite and limestone, and in pegmatite pneumatolytic deposits. It is the most important mineral raw material for molybdenum extraction. Existing research on molybdenum concentrate is diverse, with a crucial focus on determining its main content. This determination typically involves multiple batches of samples, repeated measurements, and averaging to ensure accuracy. Crushing, screening, mixing, and weighing of the molybdenum concentrate are particularly important during the sampling process. Therefore, this paper proposes an integrated device for molybdenum concentrate sample preparation, separation, and weighing. Summary of the Invention

[0004] To address the problems in the background art, this invention discloses an integrated device for molybdenum concentrate sample preparation, separation, and weighing, comprising a crushing mechanism, a sample conveying mechanism, and a feeding mechanism, thereby achieving integrated sample preparation, separation, and weighing, reducing sampling time, and improving sampling efficiency.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] An integrated device for preparing, separating, and weighing molybdenum concentrate samples includes a crushing mechanism, a sample conveying mechanism, a feeding mechanism, a rocker arm mechanism, and a bearing mechanism.

[0007] The supporting mechanism includes a vertically arranged frame;

[0008] The rocker arm mechanism includes several rocker arms that are evenly spaced along the circumference of the stand. The rocker arms are arranged radially with the stand as the center. At the end of the rocker arm away from the stand, a reagent bottle ring is provided for fitting the reagent bottle.

[0009] The feeding machine is used to quantitatively feed materials. Under the action of the driving device, the discharge end of the feeding mechanism can be rotated and stretched above any reagent bottle. The feed end of the feeding mechanism is connected to one end of the sample conveying mechanism, and the other end of the sample conveying mechanism is connected to the discharge end of the crushing mechanism. The crushing mechanism is used to crush molybdenum concentrate.

[0010] Furthermore, in the integrated molybdenum concentrate sample preparation, sorting, and weighing device, the rocker arm mechanism includes at least four rocker arms evenly spaced along the circumference of the frame.

[0011] Furthermore, in the integrated molybdenum concentrate sample preparation, sorting, and weighing device, one end of the rocking arm is fixedly connected to the upper end of the upright frame, and a rectangular frame is provided at the other end of the rocking arm. A reagent bottle rack is rotatably connected to the rectangular frame via a rocking shaft. A reciprocating contact rod is slidably connected to the rocking arm, and a ball is provided at the end of the reciprocating contact rod adjacent to the upright frame. The ball is in close contact with an elliptical contact block provided in the upper cavity of the upright frame. The elliptical contact block is fixedly connected to the output end of a second drive motor provided in the upper cavity of the upright frame. The other end of the reciprocating contact rod bends downward and extends toward the lower end of the reagent bottle. Under the action of the second drive motor, the elliptical contact block rotates and drives the reciprocating contact rod through the ball to push the reagent bottle in the reagent bottle rack to shake.

[0012] Furthermore, in the integrated molybdenum concentrate sample preparation, sorting, and weighing device, a sliding hole is provided in the middle of the rocking arm along its axial direction. The middle of the reciprocating contact rod passes through the sliding hole. A baffle is slidably connected in the sliding hole. The baffle is fixedly connected to the reciprocating contact rod. A damping spring is sleeved on the reciprocating contact rod. One end of the damping spring is fixedly connected to the baffle, and the other end is fixedly connected to the inner wall of the sliding hole.

[0013] Furthermore, the integrated molybdenum concentrate sample preparation, sorting, and weighing device includes a crushing mechanism comprising a sealed crushing cylinder with a feed chute at the top. Two first crushing shafts of unequal height are rotatably connected above and inside the crushing cylinder, and are connected by gear meshing. A second crushing shaft is located below the first crushing shafts, with one end passing through the crushing cylinder and connected to the output end of a first drive motor located outside the crushing cylinder. The second crushing shaft is connected to one of the first crushing shafts by gear meshing. Crushing toothed rollers are fixedly fitted onto the first and second crushing shafts respectively. A screening screen is located below and inside the crushing cylinder.

[0014] Furthermore, the integrated molybdenum concentrate sample preparation, sorting, and weighing device includes a small suction pump as its sample conveying mechanism. The small suction pump is fixedly installed on the outer wall of the crushing cylinder. The discharge end of the small suction pump is flexibly and sealed to the feed end of the feeding mechanism through an output telescopic pipe. The feed end of the small suction pump is connected to one end of the input pipe, and the other end of the input pipe passes through the crushing cylinder and is connected to the discharge end of the receiving hopper located below the screening screen.

[0015] Furthermore, the integrated molybdenum concentrate sample preparation, sorting, and weighing device includes a feeding mechanism comprising a hollow feeding hopper. The feeding hopper is fixedly positioned at the end of the output telescopic pipe away from the small suction pump. The outer wall of the feeding hopper is fixedly connected to one end of a horizontally positioned connecting rod. The other end of the connecting rod is connected to the output end of a servo motor located at the top of the stand. Under the action of the servo motor, the connecting rod rotates and drives the feeding hopper to rotate sequentially above the reagent bottle, allowing the feeding hopper to sequentially and quantitatively feed materials into the reagent bottle.

[0016] Furthermore, the integrated molybdenum concentrate sample preparation, sorting, and weighing device is equipped with a vibrator near the discharge port of the feeding hopper.

[0017] Furthermore, in the integrated molybdenum concentrate sample preparation, sorting, and weighing device, a transposition turntable is rotatably mounted on the upright frame. An extension frame is fixedly connected to the side of the transposition turntable. The middle part of the extension frame is fixedly connected to the middle part of the connecting rod via a connecting rod. The end of the extension frame extends to the top of the reagent bottle. An electronic scale is installed at the end of the extension frame. The electronic scale is used to hold the material quantitatively fed into the feeding hopper and verify the weight of the fed material.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention discloses an integrated molybdenum concentrate sample preparation, separation, and weighing device, comprising a crushing mechanism, a sample conveying mechanism, a feeding mechanism, a rocker arm mechanism, and a bearing mechanism. The molybdenum concentrate sample, crushed by the crushing mechanism, falls onto a sieve screen, which then further separates the sample. The entire crushing process is smooth, allowing for rapid acquisition of the required molybdenum concentrate powder. The sample conveying and feeding mechanisms deliver a quantitative amount of molybdenum concentrate powder onto a reagent bottle or electronic scale. After the electronic scale verifies the sample weight, the operator adds a quantitative amount of sample into the reagent bottle. Each reagent bottle contains an equal amount of molybdenum concentrate sample for subsequent multiple measurements, ensuring the accuracy of iron content determination. A second drive motor rotates the elliptical contact block, continuously squeezing the sphere. This causes the reciprocating contact rod to push the lower part of the reagent bottle, which in turn causes the rocker shaft to shake, allowing the molybdenum concentrate sample to fully react with the solution. This integrated sample preparation, separation, and weighing process reduces sampling time and improves sampling efficiency. Attached Figure Description

Detailed Implementation

[0027] To better understand the present invention, the following embodiments further illustrate its content, but the content of the present invention is not limited to the following embodiments. It should be noted that the innovation of the present invention lies in the structure of the integrated molybdenum concentrate sample preparation, separation, and weighing device itself. While the integrated molybdenum concentrate sample preparation, separation, and weighing device requires a control system to operate, the control system is not the innovation of the present invention and will not be described in detail here.

[0028] Combined with appendix Figure 1-6 This invention provides a detailed description of an integrated molybdenum concentrate sample preparation, sorting, and weighing device, characterized by comprising a crushing mechanism 3, a sample conveying mechanism 7, a feeding mechanism 8, a rocker arm mechanism 5, and a bearing mechanism 4.

[0029] The supporting mechanism 4 includes a vertically arranged stand 4.0, the bottom of which is fixed on the measuring table 1;

[0030] The rocker arm mechanism 5 includes several rocker arms 5.0 evenly spaced along the circumference of the upright 4.0. The rocker arms 5.0 are arranged radially with the upright 4.0 as the center. A reagent bottle ring 6 for holding reagent bottles is provided at the end of the rocker arm 5.0 away from the upright 4.0.

[0031] The feeding machine is used to quantitatively feed materials. Under the action of the driving device, the discharge end of the feeding mechanism 8 can be rotated and stretched to the top of any reagent bottle. The feed end of the feeding mechanism 8 is connected to one end of the sample conveying mechanism 7, and the other end of the sample conveying mechanism 7 is connected to the discharge end of the crushing mechanism 3. The crushing mechanism 3 is set on the measuring table 1 through the support frame 2. The crushing mechanism 3 is used to crush molybdenum concentrate.

[0032] During operation, a reagent bottle is placed on each reagent bottle rack 6, and the weighed liquid is added to each reagent bottle. The control system starts the crushing mechanism 3 and the conveying mechanism 7. The crushing mechanism 3 crushes the molybdenum concentrate, and the crushed molybdenum concentrate powder is conveyed to the feeding mechanism 8 through the sample conveying mechanism 7. The control system controls the feeding interval and feeding amount of the feeding mechanism 8 by controlling the opening and closing interval and opening time of the feeding mechanism 8. When the feeding end of the feeding mechanism 8 rotates and stretches above a reagent bottle, the control system controls the feeding end of the feeding mechanism 8 to open, and the feeding mechanism 8 feeds a quantitative amount of material into the reagent bottle. After feeding is completed, the control system controls the feeding end of the feeding mechanism 8 to close. Under the action of the drive device, the feeding end of the feeding mechanism 8 rotates and stretches above another reagent bottle, and then the above actions are repeated periodically to realize the integration of sample preparation, sample separation and weighing, reduce sampling time and improve sampling efficiency.

[0033] As an optional design, the molybdenum concentrate sample preparation, sorting, and weighing integrated device is preferred. The rocker arm mechanism 5 includes at least four rocker arms 5.0 evenly spaced along the circumference of the upright frame 4.0. A reagent bottle rack 6 is provided at the end of each rocker arm 5.0, and a reagent bottle is placed on each reagent bottle rack 6. At least four samples can be prepared at the same time each time. In actual work, five, six, seven, eight, nine, ten, or more rocker arms 5.0 can also be selected as needed.

[0034] As an optional design, the preferred integrated molybdenum concentrate sample preparation, dispensing, and weighing device includes a rocking arm 5.0 with one end fixedly connected to the upper end of a support frame 4.0. A rectangular frame is provided at the other end of each rocking arm 5.0. A reagent bottle holder 6 is rotatably connected to each rectangular frame via a rocking shaft 5.1. One end of the rocking shaft 5.1 extends outward through the rectangular frame, and a torsion spring 5.2 is fitted onto the outward extension. One end of the torsion spring 5.2 is fixedly connected to the outer surface of the rocking shaft 5.1, and the other end is connected to the outer surface of the rectangular frame. A reciprocating contact rod 5.3 is slidably connected within each rocking arm 5.0. A sphere 5.4 is provided at the end of each reciprocating contact rod 5.3 adjacent to the support frame 4.0. The sphere 5.4 interacts with an elliptical contact rod located in the upper cavity of the support frame 4.0. The elliptical contact block 4.2 is in close contact with the upper cavity of the frame 4.0. The output end of the second drive motor 4.1 is fixedly connected to the elliptical contact block 4.2. The other end of the reciprocating contact rod 5.3 is bent downwards and extends towards the lower end of the reagent bottle. Under the action of the second drive motor 4.1, the elliptical contact block 4.2 rotates and drives the reciprocating contact rod 5.3 through the ball 5.4 to shake the reagent bottle in the reagent bottle ring 6. After the reagent bottle is filled, the control system controls the second drive motor 4.1 to start. The second drive motor 4.1 drives the elliptical contact block 4.2 to rotate. The degree of contact between the elliptical contact block 4.2 and the ball 5.4 is different when the elliptical contact block 4.2 rotates. When the elliptical contact block 4.2 rotates, it drives the reciprocating contact rod 5.3 through the ball 5.4 to shake the reagent bottle in the reagent bottle ring 6, so that the material in the reagent bottle is mixed evenly.

[0035] As an optional design, the preferred integrated molybdenum concentrate sample preparation, sorting, and weighing device has a sliding hole axially formed in the middle of the rocker arm 5.0. The reciprocating contact rod 5.3 passes through the sliding hole, and a baffle 5.5 is slidably connected within the sliding hole. The baffle 5.5 is fixedly connected to the reciprocating contact rod 5.3. A damping spring 5.6 is sleeved on the reciprocating contact rod 5.3, with one end fixedly connected to the baffle 5.5 and the other end fixedly connected to the sliding contact rod 5.3. The inner wall of the moving hole is fixedly connected. During operation, when the elliptical contact block 4.2 rotates and the contact with the ball 5.4 is tight, the elliptical contact block 4.2 drives the reciprocating contact rod 5.3 through the ball 5.4 to push the reagent bottle set in the reagent bottle ring 6 to shake, so that the material in the reagent bottle is mixed evenly. At the same time, the damping spring 5.6 is compressed and accumulates potential energy. When the elliptical contact block 4.2 rotates and the contact with the ball 5.4 is loosened, the damping spring 5.6 releases the compressed potential energy, and the reciprocating contact rod 5.3 moves in the opposite direction.

[0036] As an optional design, the preferred integrated molybdenum concentrate sample preparation, sorting, and weighing device includes a crushing mechanism 3 comprising a sealed crushing cylinder 3.0. The bottom of the crushing cylinder 3.0 is mounted on the measuring platform 1 via a support frame 2. A feed chute 3.8 is provided at the top of the crushing cylinder 3.0. Two first crushing shafts 3.1 of unequal height are rotatably connected above and inside the crushing cylinder 3.0. One end of each of the two first crushing shafts 3.1 passes through the crushing cylinder 3.0 and is fitted with a first gear 3.5, which meshes with each other. The two first crushing shafts 3.1 are also meshed with each other via the two first gears 3.5. A second crushing shaft 3.2 is located below the first crushing shafts 3.1. One end of the second crushing shaft 3.2 passes through the crushing cylinder 3.0 and is connected to the output end of a first drive motor 3.4 located outside the crushing cylinder 3.0. A second gear 3.6 is fitted at the end of the second crushing shaft 3.2 that passes through the crushing cylinder 3.0. The second gear 3.6 meshes with one of the two first gears 3.5, allowing the two first crushing shafts to mesh with each other. Shaft 3.1 and the second crushing shaft 3.2 rotate synchronously, and the two first crushing shafts 3.1 rotate in opposite directions. The second crushing shaft 3.2 rotates in opposite directions to one of the first crushing shafts 3.1. Crushing toothed rollers 3.3 are fixedly sleeved on the first crushing shafts 3.1 and the second crushing shaft 3.2 respectively. A screening screen 3.7 is provided at the bottom inside the crushing cylinder 3.0. During operation, molybdenum concentrate enters the crushing cylinder 3.0 through the feed chute 3.8, the first drive motor 3.4 starts, and the second crushing shaft 3.2 rotates. The first crushing shaft 3.1 is driven to rotate, and the second crushing shaft 3.2 and the first crushing shaft 3.1 drive the crushing toothed roller 3.3 to rotate and crush the molybdenum concentrate. The crushed molybdenum concentrate sample falls onto the sieve screen 3.7, which sieves the molybdenum concentrate sample again to make the particle size of the molybdenum concentrate sample less than 300μm. The whole crushing and preparation process is smooth and can quickly obtain the required molybdenum concentrate sample powder to prepare for subsequent determination. After being sieved by the sieve screen 3.7, the molybdenum concentrate powder particles enter the receiving hopper 7.2.

[0037] As an optional design, the molybdenum concentrate sample preparation, sorting, and weighing integrated device is preferred. The sample conveying mechanism 7 includes a small suction pump 7.0, which is fixedly installed on the outer wall of the crushing cylinder 3.0. The discharge end of the small suction pump 7.0 is flexibly and sealed to the feed end of the feeding mechanism 8 through an output telescopic pipe 7.3. Since the output telescopic pipe 7.3 is a threaded telescopic pipe, when the connecting rod 8.2 drives the feeding hopper 8.0 to rotate, the output telescopic pipe 7.3 can extend and retract to adapt to the change in the position of the feeding hopper 8.0. The feed end of the small suction pump 7.0 is connected to one end of the input pipe 7.1, and the other end of the input pipe 7.1 passes through the crushing cylinder 3.0 and is connected to the discharge end of the receiving hopper 7.2 located below the screening screen 3.7. During operation, the small suction pump 7.0 is started, and the molybdenum concentrate powder particles are screened by the screening screen 3.7 and enter the receiving hopper 7.2. After passing through the input pipe 7.1 and the output telescopic pipe 7.3, they enter the feeding mechanism 8.

[0038] As an optional design, the preferred integrated molybdenum concentrate sample preparation, sorting, and weighing device includes a feeding mechanism 8 comprising a hollow feeding hopper 8.0. The feeding hopper 8.0 is fixedly positioned at the end of the output telescopic pipe 7.3 away from the small suction pump 7.0. The outer wall of the feeding hopper 8.0 is fixedly connected to one end of a horizontally positioned connecting rod 8.2. The other end of the connecting rod 8.2 is connected to the output end of a servo motor 8.1 located at the top of the upright frame 4.0. Under the action of the servo motor 8.1, the connecting rod 8.2 rotates and drives the feeding hopper 8. The feed hopper 8.0 rotates sequentially to the top of the reagent bottles, allowing it to sequentially and quantitatively dispense materials into the bottles. During operation, the control system controls the opening and closing interval and time of the servo motor 8.1, causing the servo motor 8.1 to rotate the feed hopper 8.0 by a certain central angle via the connecting rod 8.2 before pausing. This ensures that the connecting rod 8.2 can rotate the feed hopper 8.0 to the top of one reagent bottle and hold it for a certain period of time. Then, the connecting rod 8.2 continues to rotate the feed hopper 8.0 to the top of the next reagent bottle and holds it for another certain period of time.

[0039] As an optional design, the molybdenum concentrate sample preparation, sorting and weighing integrated device is preferably equipped with a vibrator 8.3 near the discharge port of the feeding hopper 8.0 to ensure smooth discharge from the feeding hopper 8.0.

[0040] As an optional design, the molybdenum concentrate sample preparation, sorting, and weighing integrated device is preferably equipped with a transposition turntable 9 rotatably mounted on the upright frame 4.0. An extension frame is fixedly connected to the side of the transposition turntable 9. The middle part of the extension frame is fixedly connected to the middle part of the connecting rod 8.2 via a connecting rod. The end of the extension frame extends to the top of the reagent bottle. An electronic scale 10 is provided at the end of the extension frame. The electronic scale 10 is used to hold the material quantitatively fed by the feeding hopper 8.0 and verify the weight of the fed material.

[0041] The working process of this invention is as follows:

[0042] The molybdenum concentrate sample is fed into the crushing cylinder 3.0 through the feed trough 3.8. The first drive motor 3.4 operates and drives the second crushing shaft 3.2 to rotate. Since the second gear 3.6 meshes with one of the first gears 3.5, the two first gears 3.5 mesh with each other, causing the two first crushing shafts 3.1 and the second crushing shaft 3.2 to rotate together. The two first crushing shafts 3.1 rotate in opposite directions, and the second crushing shaft 3.2 rotates in opposite directions to one of the first crushing shafts 3.1. This allows the crushing roller 3.3 to crush the molybdenum concentrate sample. The crushed molybdenum concentrate sample falls onto the sieve screen 3.7, which then sieves the molybdenum concentrate sample again to ensure that the particle size of the molybdenum concentrate sample is less than 300μm. The entire crushing and preparation process is smooth and quickly obtains the required molybdenum concentrate sample powder, preparing for subsequent determinations.

[0043] Solution and water are added to each reagent bottle. Initially, the feeding hopper 8.0 is positioned directly above one of the reagent bottles. The small suction pump 7.0 operates and, through the receiving hopper 7.2, input pipe 7.1, output telescopic pipe 7.3, and feeding hopper 8.0, a quantitative amount of powdered molybdenum concentrate sample is transported to the electronic scale 10. The electronic scale 10 weighs the sample again to ensure the accuracy of the weight. Then, the operator puts the sample, which has been verified by the electronic scale 10, into the reagent bottle. The vibrator 8.3 operates during the transport process to ensure that the molybdenum concentrate sample falls smoothly onto the electronic scale 10.

[0044] Servo motor 8.1 operates, driving connecting rod 8.2 to rotate at a certain angle. Connecting rod 8.2 moves feeding hopper 8.0 to directly above the next reagent bottle. At the same time, electronic scale 10 is moved above the next reagent bottle. Small suction pump 7 operates again to deliver a quantitative amount of molybdenum concentrate sample to electronic scale 10. This process continues until an equal amount of molybdenum concentrate sample is added to each reagent bottle for subsequent multiple measurements. The average value is then taken to ensure the accuracy of the determination of each component.

[0045] When a reaction occurs inside the reagent bottle, it should be removed from the electronic scale 10 in a timely manner to avoid damage to the electronic scale 10;

[0046] The second drive motor 4.1 operates, which drives the elliptical contact block 4.2 to rotate. During its rotation, the elliptical contact block 4.2 continuously squeezes the ball 5.4, causing the reciprocating contact rod 5.3 to push the lower part of the reagent bottle. Then, the swing shaft 5.1 drives the reagent bottle to shake, allowing the molybdenum concentrate sample and solution to react fully before the determination of each component. This achieves integrated sample preparation, separation, and weighing, reducing sampling time and improving sampling efficiency.

[0047] The above description is only an application embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and cannot be used to limit the scope of the rights of the present invention. Any equivalent changes made according to the technical solution of the present invention should be covered within the protection scope of the present invention.
