Description

Technical Field

[0001] This invention relates to the field of ore sorting technology, specifically to a tungsten concentrate sorting and processing equipment. Background Technology

[0002] Tungsten is a widely distributed element, found in almost all types of rocks, but in relatively low amounts. It requires geological processes to concentrate it into deposits for commercial mining. Tungsten ore is mainly divided into wolframite and scheelite. Wolframite is the most important ore for tungsten extraction; it is also called tungsten manganese iron ore. Wolframite is brown to black with a metallic or submetallic luster. Scheelite appears as granular stones, white with a yellowish tinge, and a greasy luster. It is also found in orange, bipyramidal crystals, large crystals with transparent deep orange tips. It occurs in association with calcite, muscovite, and black cassiterite, with scheelite and calcite exhibiting fluorescence. When heated or exposed to ultraviolet light, it turns slightly purple. It is a major raw material for tungsten smelting. In actual tungsten production, after the ore is mined, it is first crushed to a suitable size, and then screened. This step first classifies the ore according to particle size, separating it into large and small particle groups. The classified ore groups are then fed into a separator to separate the different types of ore. The working principle of an ore sorting machine is to use a high-speed camera to observe moving materials. When a pre-specified material is detected, a rejection mechanism sprays high-pressure gas to reject it.

[0003] The rejection mechanism of an ore sorting machine contains multiple nozzles that are directly connected to a high-pressure air source. When the rejection mechanism is working, it generally supplies nearly equal amounts of high-pressure airflow to each nozzle, meaning that it applies force evenly to all materials. Therefore, during sorting, large or small ore particles can usually only be sorted separately. This means that large ore particles are fed into one sorting machine and small ore particles into another, or the small ore particles are sorted only after all the large ore particles have been sorted, resulting in low sorting efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a tungsten concentrate sorting and processing device to solve the problems mentioned in the background art.

When the threaded rod rotates, it can drive the adjusting block to move axially. After the adjusting block contacts the left vibrating screen and the right vibrating screen, it adjusts their tilt angle. One end of the threaded rod is provided with a throttle handle.

[0009] Furthermore, the rejection mechanism includes an airflow pipe one and an airflow pipe two, each of which is provided with a plurality of nozzles. The high-pressure airflow input into the airflow pipe is discharged through the nozzles.

[0010] Furthermore, the multi-channel material distribution mechanism includes a front material distribution area and a rear material distribution area. The front material distribution area is used to separate large particle ore groups, and the rear material distribution area is used to separate small particle ore groups. A partition is provided between the front material distribution area and the rear material distribution area. The partition is used to change the area size of the front material distribution area and the rear material distribution area. The partition is hinged to the side wall of the side baffle. An upper baffle is provided on the side wall of the side baffle above the nozzle. The upper baffle is used to block small dust particles that splash upwards. The upper baffle drives the partition to be hinged through a linkage. A rear baffle is provided at the end of the rear material distribution area.

[0012] Furthermore, the frame generates vibration through a vibration mechanism, which includes a vibration motor and a shock absorber. The vibration motor drives the frame to vibrate, and the shock absorber buffers the impact force received by the frame.

[0013] Furthermore, a hopper is provided above both the left and right vibrating screens, and the hopper is used to transport the ore group into the left and right vibrating screens.

[0014] Furthermore, the conveyor belt is equipped with image acquisition module one and image acquisition module two.

[0016] This invention can simultaneously sort large and small ore particles, achieving the goal of sorting large and small ore particles of different sizes using the same sorting equipment. It can also sort four types of ore simultaneously, greatly improving sorting efficiency. Furthermore, the ore particles can be pre-distributed evenly within the vibrating screen before feeding, minimizing the gaps between adjacent particles and preventing large areas of undistributed ore. The distributed ore particles are then evenly conveyed onto the conveyor belt, further minimizing the gaps between adjacent particles and maximizing the utilization of the conveyor belt space. This also maximizes the utilization of the high-pressure gas emitted from each nozzle, improving resource utilization and sorting efficiency. Moreover, it can automatically adjust the sorting area based on the type of ore being sorted, enhancing automation. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-6This invention provides a technical solution: a tungsten concentrate sorting and processing equipment, including a conveyor belt 1 and an inclined vibrating screen 2, the vibrating screen 2 being used to convey ore groups onto the conveyor belt 1; it also includes a left vibrating screen 3 and a right vibrating screen 4, which are symmetrically distributed. During feeding, the left vibrating screen 3 and the right vibrating screen 4 alternately convey ore groups onto the vibrating screen 2; a frame 5 is provided on the outer side of both the left vibrating screen 3 and the right vibrating screen 4, and the frame 5 is equipped with a mechanism for adjusting the opening and closing of the left vibrating screen 3 and the right vibrating screen 4. The control and adjustment mechanism 6 is used to adjust the opening and closing states of the left vibrating screen 3 and the right vibrating screen 4 to opposite states; the frame 5 is equipped with an angle adjustment mechanism 7, which is used to adjust the tilt angle of the left vibrating screen 3 and the right vibrating screen 4 when feeding materials; the feeding end of the vibrating feeding screen 2 is equipped with a rejection mechanism 8 and a multi-channel material distribution mechanism 9. The rejection mechanism 8 is used to separate the specified ore into the multi-channel material distribution mechanism 9, and the multi-channel material distribution mechanism 9 is used to isolate different types of ore into the specified channels.

[0033] One end of each of the left vibrating screen 3 and the right vibrating screen 4 is hinged to the frame 5, and the other end of each is a discharge port 14. A matching discharge baffle 10 is provided at the discharge port 14. The discharge baffle 10 is hinged to the frame 5 via a hinge shaft. The discharge baffle 10 and the discharge port 14 are magnetically attracted to each other. Specifically, during the tilting process of the vibrating screen, it will generate a pushing force on the discharge baffle 10, causing one end of the discharge baffle 10 to move away from the discharge port 14. At this time, the discharge... When the discharge port 14 is opened, the ore inside the vibrating screen slides down into the vibrating feed screen 2 through the discharge port 14. When the vibrating screen returns to the horizontal position, since the inner wall of the discharge port 14 and the discharge baffle 10 are respectively provided with magnets with opposite magnetic properties, or one of them is provided with a magnet and the other is iron, the two can be magnetically attracted and attached together, thereby closing the discharge port 14 and preventing the ore inside the vibrating screen from falling down, thus achieving the purpose of automatically opening and closing the discharge port 14.

[0034] The control and adjustment mechanism 6 includes a rotating shaft 601, an elliptical disk 602, a gear 603, and a rack 604. Both ends of the rotating shaft 601 extend to be rotatably connected to the frame 5. Multiple elliptical disks 602 are fitted onto the outer wall of the rotating shaft 601 and rotate synchronously with it. When the axial endpoints of the elliptical disks 602 move away from or towards the left vibrating screen 3 and the right vibrating screen 4, the left and right vibrating screens 3 and 4 respond to the interference of the elliptical disks 602 by exhibiting a gradually tilting or gradually horizontal movement tendency. The major and minor axes of the elliptical disks 602 below the left vibrating screen 3 and the right vibrating screen 4 are perpendicularly distributed. The gear 603 is fitted onto the outer wall of the rotating shaft 601, and the rack 604 meshes with it. When the gear 603 rotates, it can drive the rack 604 to undergo axial displacement. Two racks 604 on the same axis are fixedly connected, and one end of one of the rotating shafts 601 is connected to the drive motor 6. The output shaft of 05 is fixedly connected. Specifically, the drive motor 605 is started, which drives the rotating shaft 601 to rotate. The rotating shaft 601 drives the elliptical disk 602 to rotate. The distance between the long axis end point and the short axis end point of the elliptical disk 602 and the vibrating screen is adjusted. In this invention, when the long axis end point of the elliptical disk 602 is in contact with the vibrating screen, one end of the vibrating screen can be lifted up to make the vibrating screen horizontal. When the short axis end point of the elliptical disk 602 is in contact with the vibrating screen, one end of the vibrating screen can fall down by gravity to make the vibrating screen tilted, so that the ore group inside the vibrating screen can fall. At the same time, when the rotating shaft 601 rotates, it will also drive the gear 603 to rotate. The gear 603 will drive the meshing rack 604 to move. The racks 604 below the left vibrating screen 3 and the right vibrating screen 4 will move synchronously, thereby driving the two rotating shafts 601 to rotate synchronously, so as to achieve the purpose of adjusting the synchronous rotation of multiple elliptical disks 602.

[0035] The angle adjustment mechanism 7 includes a threaded rod 701, an adjusting block 702, and a support frame 703. The support frame 703 is fixedly installed inside the frame 5. The adjusting block 702 is located at one end of the threaded rod 701, and the other end of the threaded rod 701 passes through the support frame 703. The support frame 703 has a threaded hole inside that meshes with the threaded rod 701. The outer wall of the adjusting block 702 is provided with a guide rod 704, one end of which passes through the support frame 703. When the threaded rod 701 rotates, it can drive the adjusting block 702 to move axially. After the adjusting block 702 contacts the left vibrating screen 3 and the right vibrating screen 4, it adjusts their tilt angle. One end of the threaded rod 701 is provided with a handle 705. Specifically, when it is necessary to adjust the size of the discharge port 14 when the vibrating screen tilts, the handle 705 can be used to drive the threaded rod 701 to rotate. The threaded rod 701 will move through the threaded belt... The displacement of the adjusting block 702 changes the distance between the adjusting block 702 and the end of the vibrating screen. When the vibrating screen is tilted, the adjusting block 702, after contacting the vibrating screen, can limit one end of it, preventing that end from moving down. The smaller the distance between the adjusting block 702 and the discharge port 14, the smaller the tilt angle of the vibrating screen. The larger the distance between the adjusting block 702 and the discharge port 14, the larger the tilt angle of the vibrating screen. The position of the adjusting block 702 can be pre-adjusted before use. When one end of the vibrating screen moves down to contact the adjusting block 702, it cannot move down further and maintains the current tilt angle, thereby controlling the size of the discharge port 14. This ensures that when conveying ore groups of different sizes, only one layer of ore group falls at the discharge port 14 at a time, avoiding the accumulation of ore groups and affecting subsequent sorting operations.

[0036] The rejection mechanism 8 includes an airflow pipe 1 801 and an airflow pipe 2 802. Each airflow pipe 1 801 and airflow pipe 2 802 is equipped with several nozzles 803. The high-pressure airflow input into the airflow pipe is discharged through the nozzles 803. Specifically, when sorting large ore particles, only the nozzles 803 of airflow pipe 1 801 can be used to discharge the high-pressure airflow. When sorting small ore particles, the nozzles 803 of airflow pipe 1 801 and airflow pipe 2 802 can be used simultaneously to discharge the high-pressure airflow, thereby increasing the impact area of ​​the high-pressure airflow and increasing the flow velocity of the high-pressure airflow. This can generate a larger, stronger, and wider airflow impact on the small ore particles, thus ensuring that all the small ore particles can enter the post-sorting zone 902.

[0037] The multi-channel material distribution mechanism 9 includes a front material distribution zone 901 and a rear material distribution zone 902. The front material distribution zone 901 is used to separate large particle ore groups, and the rear material distribution zone 902 is used to separate small particle ore groups. A partition plate 903 is provided between the front material distribution zone 901 and the rear material distribution zone. The partition plate 903 is used to change the size of the areas of the front material distribution zone 901 and the rear material distribution zone 902. The partition plate 903 is hinged to the side wall of the side baffle 904. Specifically, during the separation process, large particle ore groups can fall into the front material distribution zone 901 and can be divided into two channels for conveying, while small particle ore groups fall into the rear material distribution zone 902, which can also be divided into two channels. The conveying system enables the separation of four types of ore, greatly improving separation efficiency and applicability. When separating large ore particles, the partition plate 903 can be tilted towards the rear distribution area 902. Ore falling on the partition plate 903 will slide down its tilted trajectory into the front distribution area 901, thus expanding the range of the front distribution area 901. Similarly, when separating small ore particles, the partition plate 903 can be tilted towards the front distribution area 901. Ore falling on the partition plate 903 will slide down its tilted trajectory into the rear distribution area, thus expanding the range of the rear distribution area 902 and ensuring the accuracy of separation.

[0038] An upper baffle 905 is provided on the side wall of the side baffle 904 above the nozzle 803. The upper baffle 905 is used to block small dust particles that splash upwards. The upper baffle 905 is hinged to the partition plate 903 through the linkage 91. A rear baffle 906 is provided at the end of the rear material distribution area 902. Specifically, when there are fine dust particles on the conveyor belt 1, when passing through the high-pressure airflow area, the high-pressure airflow will blow the dust into the air. When it falls back into the surrounding working environment, if it accidentally falls into the working machine, it will cause damage to the machine. Therefore, the upper baffle 905 can block the splashing dust from falling and make it fall into the safe area, improving the safety of the working environment. The rear baffle 906 can block the sorting of small ore particles. After the smaller ore particles fall onto the rear baffle 906, they will fall into the rear material distribution area 902 along its inclined trajectory to ensure the reliability of sorting.

[0039] The linkage 91 includes gear 2 911, gear 3 912, and a toothed belt 913. The upper baffle 905 is hinged to the side baffle 904 via hinge shaft 2 914. Gear 2 911 is sleeved on the outer wall of hinge shaft 2 914. The partition 903 is hinged to the side baffle 904 via hinge shaft 3 915. Gear 3 912 is sleeved on the outer wall of hinge shaft 3 915. The toothed belt 913 meshes with both gear 2 911 and gear 3 912, causing gear 2 911 and gear 3 912 to rotate synchronously. The radius of gear 2 911 is larger than the radius of gear 3 912. A traction rope 916 is provided at the top of the upper baffle 905, and a connecting block 917 is provided on the outer wall of the side baffle 904. One end of the traction rope 916 extends to be fixedly connected to the connecting block 917. The traction rope 916 is used to limit the movable range of the upper baffle 905. Specifically, when sorting small particle ore groups, the upper baffle 905 is subjected to a double airflow pipe to increase the flow rate of the high-pressure airflow, which will generate a strong impact on the upper baffle 905. Plate 905 is made of plastic, so it can be easily blown up by high-pressure airflow. When one end of the upper baffle 905 flips upward, it drives hinge shaft 2 914 to rotate. Hinge shaft 2 914 drives gear 2 911 to rotate. Gear 2 911 drives the toothed belt 913 to move, which in turn drives gear 3 912 to rotate synchronously. Gear 3 912 drives hinge shaft 3 915 to rotate synchronously. Hinge shaft 3 915 drives partition plate 903 to rotate, pushing partition plate 903 towards... The front sorting zone 901 is tilted, increasing the sorting range of the rear sorting zone 902. When high-pressure gas is discharged using a single airflow pipe, one end of the upper baffle 905 will move downward under its own gravity, which will drive the partition plate 903 to move in the opposite direction, adjusting the partition plate 903 to tilt towards the rear sorting zone 902. This expands the sorting range of the front sorting zone 901, achieving the purpose of automatically adjusting the sorting area range according to different types of ore, and improving the level of automation.

[0040] The frame 5 vibrates through the vibration mechanism 15, which includes a vibration motor and a shock absorber. The vibration motor drives the frame 5 to vibrate, and the shock absorber buffers the impact force on the frame 5. Specifically, the vibration mechanism 15 is any existing mechanism that drives the vibration of an object. Any structure that can make the frame 5 vibrate is acceptable. For example, the vibration motor commonly used in the prior art drives the frame 5 to vibrate, thereby enabling the structure inside the frame 5 to rotate synchronously. Furthermore, it can drive the vibrating screen to vibrate, and the vibration amplitude and frequency of the left vibrating screen 3 and the right vibrating screen 4 are the same.

[0041] A hopper 11 is provided above both the left vibrating screen 3 and the right vibrating screen 4. The hopper 11 is used to transport the ore group into the left vibrating screen 3 and the right vibrating screen 4.

[0042] The conveyor belt 1 is equipped with an image acquisition module 12 and an image acquisition module 13. Image acquisition module 12 is used to acquire the types of ore in the conveyed ore group and the location information of different types of ore. Image acquisition module 13 is used to monitor the real-time conveying position of the ore and control the airflow of the nozzle 803 based on the ore conveying position signal. Specifically, image acquisition module 12 can be used to perform image monitoring of the ore group on the conveyor belt 1, such as using a commonly used industrial camera, and transmit the acquired images to the control system for ore processing. The types of ore in the group are analyzed, and the positions of the ore in the group are marked to control the timing of the high-pressure airflow. The image acquisition module 213 monitors the large and small ore groups in real time. Since there is a clear boundary between the large and small ore groups, when the large ore group reaches the end of the conveyor belt 1, a single airflow pipe is controlled to spray high-pressure gas. When the small ore group reaches the end of the conveyor belt 1, a double airflow pipe is controlled to spray high-pressure gas.

[0043] The specific implementation method is as follows: When sorting large and small ore particles simultaneously, the large ore particles are first fed into one of the vibrating screens, for example, the left vibrating screen 3. During the sorting process, the small ore particles are then fed into the right vibrating screen 4. The vibration of the vibrating screens evenly disperses the ore particles within them. The large ore particles in the left vibrating screen 3 are then discharged by rotating the elliptical disk 602 using the rotating shaft 601. Since the end point of the major axis of the elliptical disk 602 is in contact with the right vibrating screen 4, it lifts the right vibrating screen 4, making it horizontal. Therefore, at this time, the rotating shaft 601 is used to discharge the ore particles. The elliptical disk 602 rotates, causing its short axis end to gradually move closer to the right vibrating screen 4, while its long axis end gradually moves away from the vibrating screen. At this time, under its own gravity, the right vibrating screen 4 undergoes a hinged motion, causing one end of its discharge port 14 to move downwards, making the entire right vibrating screen 4 tilted. At this point, there is a gap between the baffle plate and the discharge port 14, allowing large ore particles to slide into the feeding vibrating screen. While the large ore particles are falling, the right vibrating screen 4 is in a closed state, allowing small ore particles to be fed inside. Similarly, the vibration force evenly distributes the small ore particles within the right vibrating screen 4. When the left vibrating screen 3... After all the large ore particles have been fed into the screen, the elliptical disk 602 is rotated again using the rotating shaft 601. The elliptical disk 602 below the left vibrating screen 3 is adjusted so that its major axis is in contact with the left vibrating screen 3. This lifts one end of the left vibrating screen 3, making it horizontal, allowing the large ore particles to continue being fed into it. Meanwhile, the elliptical disk 602 below the right vibrating screen 4 is adjusted so that its minor axis gradually approaches the bottom of the left vibrating screen 3. Under its own weight, the right vibrating screen 4 undergoes a hinged movement, causing its discharge port 14 to face downwards, allowing the small ore particles to fall into the right vibrating screen 4, thus achieving the desired effect. The purpose of alternating feeding with the right vibrating screen 4 is to clearly separate large and small ore particles on the conveyor belt 1. When the large ore particles move to the discharge end of the conveyor belt 1, they are separated by high-pressure airflow, causing different types of ore particles to fall into two different channels in the front distribution area. When the small ore particles move to the discharge end of the conveyor belt 1, the flow rate of the high-pressure airflow is increased, blowing the small ore particles into the rear distribution area 902. Thus, the same sorting equipment can be used to sort large and small ore particles of different sizes, and four types of ore can be sorted at the same time, greatly improving the sorting efficiency.

[0044] When it is necessary to separate large or small ore particles, the weight of the ore particles to be fed can be preset. Then, the ore particles are fed into the left vibrating screen 3 and the right vibrating screen 4 according to the preset value. At this time, the vibrating screen will vibrate and disperse the ore particles inside, so that the ore particles inside the vibrating screen are evenly distributed. In this process, since the weight of the ore particles to be fed is calculated in advance, the interval between two adjacent ore particles after vibration distribution is small. This maximizes the utilization of the available space in the vibrating screen and avoids the situation where there are large spaces where ore particles are not distributed. Then, they are sequentially fed into the vibrating feed screen 2 and conveyed to the conveyor belt 1. This allows the ore particles to be evenly distributed on the conveyor belt 1, and the interval between two adjacent ore particles is small, so that the conveying space on the conveyor belt 1 can be maximized. At the same time, the high-pressure gas sprayed by the nozzle 803 can be maximized, improving resource utilization and sorting efficiency.
