Description

Technical Field

[0001] This utility model belongs to the field of mineral processing, specifically relating to a feeding mechanism and a mineral processing machine. Background Technology

[0002] Centrifugal separation is an important physical mineral processing method that separates mineral particles based on differences in particle diameter and density within a centrifugal force field generated by high-speed rotation. It is an enhancement and extension of gravity separation technology. The device used for centrifugal separation is called a mineral processing machine.

[0003] A conventional mineral processing machine mainly consists of a centrifugal drum for mineral processing and a drive structure for rotating the drum. The ore slurry enters the centrifugal drum, and the drive structure rotates the drum, thus achieving centrifugal separation of the ore slurry. For a reference, see application number CN202220306672.5, entitled "A Centrifugal Mineral Processing Equipment for Ore Processing."

[0004] However, in existing mineral processing machines, the material enters in an uneven state during feeding, and the material tends to accumulate in a certain area or place of the centrifuge, which in turn affects the separation effect of mineral processing. Utility Model Content

[0005] This utility model provides a feeding mechanism and a mineral processing machine, the purpose of which is to solve the problem of uneven feeding.

[0006] To achieve the above objectives, this utility model provides a feeding mechanism, including... The material distribution plate is set below the feed inlet so that the slurry is released from the feed inlet onto the material distribution plate. The contact surface between the material distribution plate and the slurry forms multiple guide channels. A transmission component, wherein the material distribution disc is connected to the transmission component for transmission, the transmission component is used for transmission connection with the power structure, and the transmission component is used to drive the material distribution disc to rotate; and a guide cylinder, wherein the material distribution disc is housed inside the guide cylinder.

[0007] In this scheme, the slurry is fed through the inlet and reaches the distribution plate. The distribution plate rotates, thus dispersing the slurry under gravity and centrifugal force, and guiding it into the guide tube. After distribution, the slurry continues to move through the guide tube. This scheme achieves dispersed feeding, preventing slurry accumulation in one place and overcoming the shortcomings of existing technologies.

[0008] Preferably, in order to achieve better material distribution effect, the feed inlet of this solution corresponds to the middle area of ​​the material distribution plate, and the entrance of the guide channel is located in the middle area of ​​the material distribution plate.

[0009] By aligning the feed inlet with the center of the distribution plate, the slurry arrives at the center of the distribution plate. When the slurry is in the center, it experiences a more uniform centrifugal force from the plate, resulting in better distribution.

[0010] Preferably, in order to construct the guide channel, the guide channel of this solution is directly constructed on the upper surface of the material distribution plate.

[0011] Alternatively, in order to construct a guiding channel, the surface of the material distribution plate in this solution is provided with multiple guide vanes, which cooperate to form the guiding channel.

[0012] Preferably, the guide channel is arc-shaped.

[0013] Preferably, the material distribution plate is in a horizontal position, and the guide tube is in a vertical position.

[0014] Preferably, to guide the incoming material, this solution further includes a feed pipe, which forms the feed inlet. This solution uses the feed pipe to initially guide the slurry, allowing the slurry to be released more precisely into the center of the distribution plate.

[0015] Preferably, to achieve the rotation of the dispensing disc, the power structure in this solution is connected to the feed pipe, and the feed pipe is fixedly connected to the transmission component. The power structure drives the feed pipe to rotate, causing the transmission component to rotate accordingly. In this solution, the power structure drives the feed pipe to rotate, which in turn drives the transmission component to rotate. Finally, the transmission component drives the dispensing disc to rotate.

[0016] The second aspect of this utility model discloses a mineral processing machine, including the aforementioned feeding mechanism. By applying the aforementioned feeding mechanism to the mineral processing machine, the ore slurry is fed evenly, achieving better mineral processing results.

[0017] Preferably, after the ore slurry is fed, in order to achieve ore slurry separation, this solution also includes a mineral processing unit and a pulse water mechanism. The mineral processing unit includes a cylindrical screen and a ore cylinder. The cylindrical screen is connected to the guide cylinder, so that the ore slurry enters the interior of the cylindrical screen from the guide cylinder. The cylindrical screen is housed inside the ore cylinder. The outer wall of the cylindrical screen and the inner wall of the ore cylinder form a mineral processing chamber, and the mineral processing chamber is provided with a discharge port. The pulse water mechanism includes a water injection nozzle, which is fixedly installed. The water injection nozzle is used to intermittently inject water into the rotating mineral processing chamber, so that a pulse water flow is formed on the inner wall of the cylindrical screen.

[0018] Preferably, in order to collect the light minerals located on the inner wall of the cylindrical screen, this solution further includes a collection mechanism, which has a first collection channel communicating with the interior of the cylindrical screen. The light minerals located on the inner wall of the cylindrical screen fall into the first collection channel due to the combined action of water flow and gravity, and the first collection channel collects the light minerals.

[0019] To collect heavy minerals located in the beneficiation chamber, this solution also includes a collection mechanism with a second collection channel connected to the discharge port. Heavy minerals in the beneficiation chamber fall from the discharge port into the second collection channel, which collects the heavy minerals.

[0020] To facilitate the recirculation of water that did not enter the ore dressing chamber, this solution also includes a collection mechanism with a third collection channel. This third collection channel is used to recover the water from the pulse water mechanism. By setting up the third collection channel, water that did not enter the ore dressing chamber enters the third collection channel, thus achieving water recovery.

[0021] The beneficial effects of this invention are as follows: In this design, the slurry is added through the feed inlet and reaches the distribution plate from the feed inlet. The distribution plate is rotating, so the slurry on the distribution plate is dispersed under centrifugal force and introduced into the guide tube. After distribution, the slurry continues to move through the guide tube. This design achieves dispersed feeding through the above method, preventing the slurry from accumulating in one place.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0029] The basic implementation examples are as follows: Figure 1 As shown, a feeding mechanism includes a feeding pipe 1, a distributing plate 2, a guide tube 3, a transmission component 4, and a power structure 5.

[0030] In this embodiment, the feed pipe 1 is a cylindrical hollow pipe, through which the slurry enters. The feed pipe 1 is connected to the power structure 5 in a transmission connection. When the power structure 5 operates, it drives the feed pipe 1 to rotate. The power structure 5 mainly includes a motor 51, a transmission pulley, and a follower pulley. The motor 51 is fixedly installed, and the transmission pulley is mounted on the output shaft of the motor 51. The operation of the motor 51 drives the transmission pulley to rotate. The follower pulley is mounted on the feed pipe 1, and the follower pulley and the transmission pulley are connected by a belt 52. The motor 51 drives the feed pipe 1 to rotate inside the support pipe 93 through the belt 52.

[0031] In this embodiment, a transmission component 4 is provided at the lower end of the feed pipe 1. The transmission component 4 is a circular plate and is concentrically arranged with the feed pipe 1. A connecting channel is constructed in the middle of the transmission component 4, which communicates with the interior of the feed pipe 1, allowing the slurry to pass through the transmission component 4. Specifically, the transmission component 4 can be welded to the bottom of the feed pipe 1. When the feed pipe 1 rotates, the transmission component 4 rotates accordingly.

[0032] It should be noted that, in this embodiment, the feed pipe 1 is preferably connected to the power structure via a transmission connection. However, in some other embodiments, the power structure 5 can also be directly connected to the transmission component 4 via a transmission connection. For example, a gear can be mounted on the transmission component 4, and the gear can mesh with the output shaft of the motor 51 for transmission connection. The motor 51 can then drive the transmission component 4 to rotate directly.

[0033] In this embodiment, the distributing disc 2 is positioned below the transmission component 4. The distributing disc 2 is preferably disc-shaped and concentrically arranged with the transmission component 4. The distributing disc 2 and the transmission component 4 are fixedly connected by a connector, which can be a connecting rod or a connecting piece, etc. Both ends of the connector are welded to the transmission component 4 and the distributing disc 2 or fastened together. The connector serves to fix the distributing disc 2, ensuring it is stably positioned directly below the outlet of the feed pipe 1, and allowing the distributing disc 2 to rotate with the transmission component 4. Simultaneously, the connector creates space between the distributing disc 2 and the transmission component 4, preventing slurry blockage. The outlet of the distributing pipe faces the central area of ​​the distributing disc 2. Slurry entering from the feed pipe 1 falls directly into the central area of ​​the distributing disc 2. Under the centrifugal force of the rotating distributing disc 2, the slurry moves to the edge of the distributing disc 2. The guide cylinder 3 is a cylindrical body. The upper end of the guide cylinder 3 is fixedly connected to the transmission component 4 by welding. The interior of the guide cylinder 3 houses the distribution plate 2. The guide cylinder 3 and the distribution plate 2 are concentrically arranged. The guide cylinder 3 is driven to rotate by the transmission component 4. The slurry enters the inner wall of the guide cylinder 3 from the distribution plate 2. Then, under the action of the water flow (containing water in the slurry) and the driving force generated by the continuous conveying of the slurry, the slurry moves along the inner wall of the guide cylinder 3 to the lower end of the guide cylinder 3.

[0034] like Figure 2 As shown, to achieve better material distribution, the surface of the material distribution plate 2 in this embodiment is constructed with an arc-shaped guide channel 21, which extends from the central region of the material distribution plate 2 to its edge. Preferably, multiple guide channels 21 are provided and evenly distributed. Specifically, the guide channel 21 can be formed by providing guide vanes on the surface of the material distribution plate 2, or it can be directly formed by creating a recessed guide channel 21 on the surface of the material distribution plate 2. The inlet of the guide channel 21 is located in the central region of the material distribution plate 2. Simultaneously, a guide cone, which is conical in shape, is provided in the central region of the material distribution plate 2. Located in the center of the material distribution plate 2, when the slurry falls from the feed pipe 1, the slurry contacts the guide cone, which then provides a certain material distribution effect.

[0035] The following describes the working process of the feeding module: Both the distribution plate 2 and the guide cylinder 3 in the distribution module are rotating. The slurry entering from the feed pipe 1 falls into the middle of the distribution plate 2. Because the distribution plate 2 is rotating, it distributes the slurry, which then moves to the inner wall of the guide cylinder 3. Subsequently, under the influence of the water flow (containing water) and the driving force generated by the continuous transport of the slurry, the slurry moves along the inner wall of the guide cylinder 3 to the lower end of the guide cylinder 3.

[0036] Example 2 This embodiment provides a mineral processing machine, such as... Figures 3 to 5As shown, it includes the feeding mechanism, mineral processing mechanism 6, pulse water mechanism 7, collection mechanism 8, and frame 9 of Embodiment 1.

[0037] like Figure 3 As shown, the frame 9 in this embodiment serves as the mounting base and includes legs 91, a mounting plate 92, and a support tube 93. Multiple legs 91 are located at the bottom, with their bottoms contacting the ground. The upper ends of the legs 91 are used to mount the mounting plate 92. The mounting plate 92 is preferably horizontally positioned, with the support tube 93 mounted in the middle. The support tube 93 is preferably vertically positioned, with its internal channel passing through the mounting plate 92 and communicating with its bottom. The mounting plate 92 and legs 91, as well as the mounting plate 92 and support tube 93, can be connected by welding or fasteners to ensure the stability of the legs 91, mounting plate 92, and support tube 93.

[0038] In this embodiment, the feed pipe 1 of the feeding mechanism is housed inside the support pipe 93. Meanwhile, to ensure the rotation of the feed pipe 1, a bearing is provided between the feed pipe 1 and the support pipe 93. The bearing allows the feed pipe 1 to rotate inside the support pipe 93, and the feed pipe 1 is kept in a stable state by the bearing.

[0039] In this embodiment, the mineral processing mechanism 6 is located below the feeding mechanism. Specifically, the mineral processing mechanism 6 includes a cylindrical screen 61 and a ore cylinder 62. The cylindrical screen 61 is cylindrical, and its top is fixedly connected to the bottom of the guide cylinder 3, allowing the ore slurry on the inner wall of the guide cylinder 3 to fall and move to the inner wall of the guide cylinder 3. The cylindrical screen 61 and the guide cylinder 3 are concentrically arranged. The cylindrical screen 61 and the guide cylinder 3 can be directly connected by welding, or by setting an embedding groove at the bottom of the guide cylinder 3, embedding the top of the cylindrical screen 61 into the embedding groove, and then fixing it by fasteners or adhesives to achieve a stable connection between the cylindrical screen 61 and the guide cylinder 3. In this embodiment, the cylindrical screen 61 has uniformly distributed screen holes, and bed stones are provided on the inner wall of the cylindrical screen 61. The bed stones can be materials with a diameter larger than the screen holes, such as iron (steel) balls or iron (steel) shot. The bed stones cannot pass through the screen holes, preventing bed stone loss. Simultaneously, as the cylindrical screen 61 rotates with the guide cylinder 3, the bed stones are stably positioned on the inner wall of the cylindrical screen 61 under centrifugal force without falling downwards. Of course, after the centrifugal force disappears, the bed stones naturally fall, achieving bed stone recovery. A horizontal baffle is provided at the bottom of the cylindrical screen 61. The baffle is annular, and its inner ring is integrally formed with the inner wall of the cylindrical screen 61. The ore cylinder 62 is also cylindrical, but its diameter is larger than that of the cylindrical screen 61, allowing the cylindrical screen 61 to be housed within its inner ring. The ore cylinder 62 and the cylindrical screen 61 are concentrically positioned. The bottom of the ore cylinder 62 is fixedly connected to the baffle at the bottom of the cylindrical screen 61, keeping the bottom closed. In implementation, fasteners can be used to fix the baffle to the bottom of the ore cylinder 62. The top of the ore cylinder 62 is fixedly connected to the transmission component 4, allowing the ore cylinder 62 to rotate with the transmission component 4, while the top of the ore cylinder 62 remains closed.

[0040] In this embodiment, the enclosed cavity between the outer wall of the cylindrical screen 61 and the inner wall of the ore cylinder 62 is referred to as the ore dressing chamber. The ore dressing chamber is circular in shape and is a closed compartment. During ore dressing, the amount of water entering the ore dressing chamber is greater than the amount of water exiting the ore dressing chamber from the discharge port 622, thus ensuring that the ore dressing chamber is filled with water. A collection bin 621 is constructed on the outer side of the ore dressing chamber. The collection bin 621 is conical, specifically a pyramidal or conical shape, and is connected to the interior of the ore dressing chamber. When the ore cylinder 62 is rotating, the minerals inside the ore dressing chamber converge toward the collection bin 621 under the action of centrifugal force. Multiple collection bins 621 are provided, preferably 8 to 24, and the multiple collection bins 621 are distributed in a circular pattern in the ore dressing chamber. In order to allow the sorted minerals to exit the ore dressing chamber, a discharge port 622 is provided on the collection bin 621. The discharge port 622 is circular or rectangular, and its diameter is preferably 1 to 6 mm. The discharge port 622 is preferably located at the top of the collection bin 621 to ensure better discharge effect.

[0041] In this embodiment, the pulse water mechanism 7 is used to create a pulsed water flow on the sidewall of the cylindrical screen. The pulse water mechanism 7 includes a water tank 71, a water pipe, a water inlet 72, and a mating component 73. The water tank 71 is located outside the device and contains tap water. The pressure inside the water tank 71 is 0.2~0.6 kg / cm². 2 A water pipe is installed at the outlet of water tank 71, and the water pipe is connected to water inlet 72. Tap water inside water tank 71 reaches the injection component through the water pipe and is discharged outwards from the injection component. Water inlet 72 is fixedly mounted on mounting plate 92 and does not rotate. A mating component 73 is fixedly mounted on transmission component 4. The mating component 73 is block-shaped, with a water inlet at its top and a connecting channel inside the mating component 73 that communicates with the interior of the ore dressing chamber. The mating component 73 rotates along with the ore dressing chamber. There are 4 to 8 pairs of water inlet nozzles 72 and mating components 73.

[0042] When the rotating mating component 73 rotates to a position below the water inlet 72, the water inlet 72 and the mating component 73 are aligned. The pulsed water discharged from the water inlet 72 enters the ore dressing chamber through the mating component 73. After the pulsed water enters the ore dressing chamber, an upward water flow is formed on the inner wall of the cylindrical screen. When the rotating mating component 73 rotates to a position offset from the water inlet 72, the pulsed water discharged from the water inlet 72 cannot enter the ore dressing chamber. Since the discharge port 622 is still discharging ore slurry, a downward water flow is formed on the inner wall of the cylindrical screen. The upward and downward water flows repeat, forming a pulsed water flow on the inner wall of the cylindrical screen.

[0043] To reduce the impact of water flow in the ore slurry on the cylindrical screening process, this embodiment preferably includes a funnel-shaped guide ring at the bottom of the guide cylinder 3. When pulsed water enters the beneficiation chamber, the water flows along the direction of the guide ring due to its shape, thus separating the water from the ore slurry.

[0044] The following describes the mineral processing process achieved by the combination of the mineral processing unit 6 and the pulse water mechanism 7: The slurry moves downward along the inner wall of the guide cylinder 3, eventually entering the inner wall of the cylindrical screen 61. Under the action of centrifugal force and pulse water, a material layer is formed on the inner wall of the cylindrical screen 61. Then, when the pulse water enters the processing chamber, an upward water flow is formed on the inner wall of the cylindrical screen. This upward water flow passes through the cylindrical screen 61 and contacts the material layer. The material layer is loosened by the impact of the upward water flow. At this time, minerals of different weights, due to their different settling velocities and densities, will shift their positions. Heavier coarse mineral particles settle, while lighter particles float. When the pulse water does not enter the processing chamber, a downward water flow is formed on the inner wall of the cylindrical screen. Simultaneously, under the action of centrifugal force, a "separation" phenomenon occurs, that is, heavier coarse mineral particles move towards the screen surface of the cylindrical screen 61. As the cylindrical screen 61 and the beneficiation chamber continue to rotate, the above process continues. Under the continuous action of the pulsed water flow, the minerals are stratified according to their density. The stratification result is that the bed rock, due to its high density and particle size, is located at the bottom. The minerals separated from the bed rock at the bottom of the cylindrical screen 61 are, from bottom to top, high-density coarse-grained minerals, followed by high-density fine-grained minerals, then low-density coarse-grained minerals, then low-density medium-density minerals. The low-density fine-grained minerals remain on the surface of the bed layer and cannot enter the lower layers. Then, under the continuous action of centrifugal force and pulsed water, the high-density minerals at the bottom pass through the bed rock layer and enter the beneficiation chamber through the screen openings, and are discharged from the beneficiation chamber through the discharge port 622 of the collection bin 621. The remaining minerals located on the inner wall of the cylindrical screen 61 are discharged from the bottom of the cylindrical screen 61 under the impetus of the water flow and continuous feed, achieving selective separation.

[0045] It should be noted that in this embodiment, when it is necessary to adjust the beneficiation yield distribution, it is not necessary to adjust the rotation speed; only the particle size and thickness of the bed rock need to be adjusted. The finer the bed rock particle size and the thicker the bed rock, the fewer minerals pass through it; conversely, the coarser the bed rock particle size and the thinner the bed rock, the more minerals pass through it.

[0046] To collect the discharged ore slurry and excess pulse water, this embodiment includes a collection mechanism 8 at the bottom of the mineral processing unit 6. The collection mechanism 8 comprises a first collection channel 81, a second collection channel 82, and a third collection channel 83. Specifically, the first collection channel 81 is in communication with the inner wall of the cylindrical screen 61, allowing the ore slurry discharged from the inner wall of the cylindrical screen 61 to be discharged into and collected through the first collection channel 81. The second collection channel 82 is in communication with the discharge port 622, allowing the ore slurry discharged from the discharge port 622 to be discharged into and collected through the second collection channel 82. When the water injection nozzle 72 and the mating component 73 are not aligned, the pulse water discharged from the injection component flows from the top of the rotating plate and eventually flows into the third collection channel 83, where the pulse water is collected and recycled.

[0047] To form the first collection channel 81, the second collection channel 82, and the third collection channel 83, this embodiment has a third collection cylinder fixedly installed at the bottom of the mounting plate 92. The interior of the third collection cylinder is the third collection channel 83. The bottom of the third collection cylinder is closed, and a water recovery port is constructed on its side. Pulsed water discharged from the rotating plate enters the third collection channel 83, is collected through the third collection channel 83, and is recovered from the water recovery port. A second collection cylinder is installed inside the third collection cylinder, and the interior of the second collection cylinder is the second collection channel 82. The second collection cylinder is also a cylindrical body, and its side is fixedly connected to the bottom of the third collection cylinder to ensure that the second collection cylinder is in a stable state and does not rotate. The bottom of the second collection cylinder is closed, and a heavy mineral collection port is provided on its side. The inlet of the second collection cylinder is connected to the discharge port 622, so that the heavy minerals discharged from the discharge port 622 can be collected and aggregated by the second collection cylinder and finally discharged from the heavy mineral collection port. The first storage cylinder is installed inside the second storage cylinder, and the first storage cylinder has a first collection channel 81 inside. The first storage cylinder is also a cylindrical body, and its side is fixedly connected to the bottom of the second storage cylinder to ensure that the first storage cylinder is in a stable state and does not rotate. The bottom of the first storage cylinder is closed, and a light mineral collection port is provided on its side. The inlet of the first storage cylinder is in communication with the inner ring of the cylindrical screen 61, so that the light minerals discharged from the inner wall of the cylindrical screen 61 can be collected and aggregated by the first storage cylinder and finally discharged from the light mineral collection port.

[0048] To facilitate the installation of the bed stone on the inner wall of the cylindrical sieve 61, this embodiment includes an installation cylinder inside the first receiving cylinder. The lower end of the installation cylinder is connected to the outside, and the upper end of the installation cylinder is aligned with the inner ring of the cylindrical sieve 61. The interior of the installation cylinder is for workers to enter, and workers use the installation cylinder to install the bed stone onto the inner wall of the cylindrical sieve 61. Of course, to prevent light minerals from leaking from the installation cylinder, in this embodiment, the diameter of the installation cylinder is smaller than that of the cylindrical sieve 61, so that light minerals falling from the inner wall of the cylindrical sieve 61 fall into the first collection channel 81.

[0049] The following detailed description illustrates the specific implementation method: The slurry enters through the feed pipe 1. Guided by the feed pipe 1, the slurry falls onto the surface of the rotating distribution disc 2. The rotating distribution disc 2 distributes the slurry through rotation. The slurry reaches the inner wall of the guide cylinder 3. Under the driving force generated by the water flow and the continuous transport of the slurry, the slurry moves along the inner wall of the guide cylinder 3 to the lower end of the guide cylinder 3 and finally reaches the cylindrical screen 61. On the cylindrical screen 61, the slurry is subjected to the interaction of centrifugal force and pulsed water flow, causing heavy and light minerals to separate into layers. Light minerals are collected by the first collection channel 81 and eventually discharged from the light mineral collection port. Heavy minerals are collected by the second collection channel 82 and discharged from the heavy mineral collection port.

[0050] When it is necessary to adjust the yield and grade of heavy minerals, staff only need to adjust the particle size and thickness of the bed rock.
