Description

Technical Field

[0001] This invention relates to the field of metal roughing technology, and more particularly to a column-type short-process tungsten roughing process and equipment. Background Technology

[0002] my country possesses extremely rich tungsten resources, ranking first in the world in both tungsten ore reserves and mining scale. Currently, more than 20 types of tungsten minerals have been discovered, among which wolframite and scheelite have the greatest industrial value. These minerals are often associated with various useful minerals such as bismuthite, aluminite, pyrite, pyrrhotite, and cassiterite. Gangue minerals typically include fluorite, garnet, calcite, quartz, and feldspar. Tungsten minerals usually coexist closely with other minerals, exhibiting fine and uneven intergrowth. Furthermore, while many gangue minerals share similar floatability with tungsten minerals, the floatability of wolframite and scheelite differs significantly, resulting in varying flotation conditions. Therefore, it is difficult to determine reasonable grinding fineness and separation processes to obtain various ideal products, contributing to the challenges of tungsten mineral beneficiation in my country.

[0003] Existing column-type short-process tungsten roughing equipment requires manual addition of additives to the raw ore during the preparation of flotation feed. This process causes the equipment to be idle and waiting. The inability to automatically add additives prolongs the roughing process time and reduces the roughing efficiency of the equipment. Summary of the Invention

[0004] This invention discloses a column-type short-process tungsten roughing process and equipment, aiming to solve the technical problem in the background art that existing roughing equipment cannot automatically add additives.

[0005] The column-type short-process tungsten roughing process proposed in this invention includes the following steps:

[0006] The tungsten roughing ore is fed into the roughing equipment, and an activator is added at the same time. After the slurry is prepared, it enters the slurry preparation tank. Inhibitors are added in the slurry preparation tank and stirring is continued. Then the slurry enters the slurry preparation tank and a collector is added and stirred to prepare the flotation feed.

[0007] The feed material is transported to the roughing flotation column by a roughing feed pump for flotation separation. The roughing concentrate flows into the cleaning flotation column by gravity due to the height difference between the roughing flotation column and the cleaning flotation column. The roughing tailings are discharged from the tailings outlet at the bottom of the roughing flotation column.

[0008] The roughing concentrate is further separated in the cleaning flotation column, and the cleaned concentrate flows out from the concentrate cell outlet at the top of the cleaning flotation column; the cleaned tailings flow into the middlings buffer tank from the tailings inlet at the bottom of the cleaning flotation column, and the slurry in the buffer tank is transported to the roughing slurry tank by the middlings return pump and re-enters the tungsten roughing operation.

[0009] The aforementioned column-type short-process tungsten roughing equipment includes a barrel for preparing flotation feed. A top cover is fixedly connected to the inner wall of the barrel, and a circular hole is opened on the top cover. A feed hopper is fixedly connected to the circular hole, and a fixed platform is fixedly connected to the outside of the barrel. A quantitative addition module is set on the fixed platform, and a replacement and replenishment module is set below the fixed platform. A mixing tank is set inside the barrel, and a uniform stirring module is set inside the mixing tank. A protective cover is bolted to the upper side of the top cover. A fine hole is opened on the outside of the barrel, and a discharge pipe is bolted to the fine hole. One end of the discharge pipe is located inside the mixing tank, and the other end is located outside the barrel.

[0010] Equipped with a top cover, feed hopper, protective cover, fixed platform, quantitative addition module, replacement and replenishment module, uniform stirring module, mixing tank, and discharge pipe, the device utilizes the quantitative addition module to replenish additives promptly after the addition of tungsten ore to the mixing tank. This reduces equipment downtime, maintains continuity throughout the entire preparation process, ensures smooth preparation, and improves the efficiency of the equipment's roughing feed.

[0011] In a preferred embodiment, the quantitative addition module includes a mounting platform. The mounting platform is bolted to the side opposite to the fixed platform. A receiving box is bolted to the upper side of the mounting platform. The receiving box has a circular slot. A rotating cylinder is movably connected to the inner wall of the circular slot. Discharge ports are formed on both the outer side of the rotating cylinder and the inner wall of the circular slot. A conveying pipe is bolted to the inner wall of the discharge port on the circular slot. The end of the conveying pipe away from the circular slot passes through the outside of the container and is located above the mixing tank. A slot is formed on the upper side of the receiving box, and a storage cylinder is bolted to the slot. The inner wall of the rotating cylinder has two circumferentially equidistant grooves. The same rotating component is slidably connected within the two grooves. An inlet is formed on the outer side of the rotating cylinder. A beveled groove is formed on the outer side of the rotating component, and the beveled groove and the inlet are on the same plane. Two circumferentially equidistant cutting grooves are formed on the side of the rotating cylinder away from the fixed platform. A stop block is slidably connected within each cutting groove, and the stop block is opposite to the rotating component. One side is snapped in place, and the side of the stop block opposite the inner wall of the groove is bolted to a spring. The outside of the rotating part is bolted to an external toothed ring. A vertical groove is opened on the outside of the barrel, and a connecting rod is slidably connected in the vertical groove. A rack is bolted to the upper side of the connecting rod, and the rack meshes with the external toothed ring. A top block is bolted to the upper side of the mixing barrel, and the upper side of the top block is in contact with the bottom of the connecting rod. A rectangular groove is opened on the inner wall of the bottom of the barrel, and two symmetrical movable blocks are slidably connected in the rectangular groove. A push rod is movably connected to the upper side of each of the two movable blocks. A stabilizing plate is movably connected to the end of each push rod away from the movable block. The upper side of the stabilizing plate is bolted to the bottom of the mixing barrel. Four circumferentially distributed fixing rods are bolted to the outside of the stabilizing plate, and the outside of each fixing rod is in contact with the outside of the mixing barrel. Two connecting plates are bolted to the outside of each of the two movable blocks. A spring is bolted to the opposite side of the two connecting plates on the same side.

[0012] By incorporating a quantitative addition module, which utilizes rotating components and a rotating cylinder, the device can automatically deliver a quantitative amount of additives based on the amount of tungsten ore added. This ensures process continuity while reducing excessive additive addition, minimizing resource waste, and improving economic efficiency.

[0013] In a preferred embodiment, the replacement module includes a fixing frame, which is located outside the barrel. A support plate is mounted on the fixing frame, and a fitting frame is bolted to the upper side of the support plate. A replenishment box is housed inside the fitting frame, with its bottom fitting against the upper side of the support plate. A circular hole is formed on the upper side of the replenishment box, and a extraction tube is slidably connected within the hole. A connecting frame is bolted to the outside of the extraction tube, and the side of the connecting frame opposite the barrel is bolted to it. A pump is bolted to the upper side of the connecting frame, and the pump's output end is connected to the extraction tube via a conduit. The extraction tube is connected to the upper side of the storage cylinder via a flange at the end furthest from the replenishment box. A boss is bolted to the side of the bonding frame furthest from the replenishment box. A shaft is slidably connected within the boss. The upper and lower sides of the shaft are bolted to the outside of the fixing frame. A groove is provided on the upper side of the fixing frame, and a lead screw is movably connected within the groove. A second boss is provided on the outside of the lead screw. The side of the second boss opposite the bonding frame is bolted to the second boss. A motor is bolted to the upper side of the fixing frame, and the output end of the motor is connected to the upper side of the lead screw via a coupling.

[0014] The device is equipped with a replacement and replenishment module, which uses a lead screw and support plate to quickly replace the replenishment box, reducing the workload of the staff and allowing the device to receive additives continuously, thus minimizing interference with the device's preparation process.

[0015] In a preferred embodiment, the uniform stirring module includes a main shaft. A slot is formed on the upper side of the top cover, and the inner wall of the slot is movably connected to the outside of the main shaft. Four symmetrical crossbars (I) are bolted to the outside of the main shaft. A secondary shaft is movably connected to two crossbars (I) on the same side. Gears are bolted to the outside of each secondary shaft, and the gears are located on the upper side of the crossbars (I). Three circumferentially distributed positioning plates are bolted to the bottom of the top cover. A single internal gear ring is bolted to the bottom of each of the three positioning plates, and two gears mesh with the internal gear ring. Two symmetrical crossbars (II) are bolted to the outside of each of the two secondary shafts. Two symmetrical round rods are bolted to the opposite side of each of the two crossbars (II) on the same secondary shaft. Multiple equidistant stirring rods are bolted to the outside of each of the two round rods. A motor (II) is bolted to the top inner wall of the protective cover, and the output end of the motor (II) is connected to the upper side of the main shaft via a coupling.

[0016] By incorporating a uniform stirring module, which utilizes gears and an internal gear ring to enable the secondary shaft to rotate around the main shaft while simultaneously driving the circular rod to rotate on its own axis, the stirring effect of the device is enhanced. This allows the tungsten ore to fully contact the additives, ensuring the stirring effect and improving the efficiency of preparing the roughing feed.

[0017] As can be seen from the above, the column-type short-process tungsten roughing process and equipment provided by the present invention can replenish the additives in a timely manner after adding tungsten ore to the mixing tank using a quantitative addition module, thereby reducing equipment downtime, maintaining the continuity of the entire preparation process, ensuring the smoothness of preparation, and improving the efficiency of equipment preparation of roughing feed.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The column-type short-process tungsten roughing process and equipment disclosed in this invention are mainly applied to scenarios where existing roughing equipment cannot automatically add additives.

[0028] The column-type short-process tungsten roughing process includes the following steps:

[0029] S1. The tungsten roughing ore is fed into the roughing equipment, and an activator is added at the same time. After the slurry is prepared, it enters the slurry preparation tank. An inhibitor is added in the slurry preparation tank and stirring is continued. Then the slurry enters the slurry preparation tank and a collector is added and stirred to prepare the flotation feed.

[0030] S2. The flotation feed is transported to the roughing flotation column by the roughing feed pump for flotation separation. The roughing concentrate flows into the cleaning flotation column by gravity due to the height difference between the roughing flotation column and the cleaning flotation column. The roughing tailings are discharged from the tailings outlet at the bottom of the roughing flotation column.

[0031] S3. The roughing concentrate is further separated in the cleaning flotation column. The cleaned concentrate flows out from the concentrate trough outlet at the top of the cleaning flotation column. The cleaned tailings flow into the middlings buffer tank from the tailings outlet at the bottom of the cleaning flotation column. The slurry in the buffer tank is transported to the roughing slurry preparation tank by the middlings return pump and re-enters the tungsten roughing operation.

[0032] The aforementioned column-type short-process tungsten roughing equipment, such as Figure 1-7 As shown, the roughing equipment includes a barrel 1 for preparing flotation feed. A top cover 2 is bolted to the inner wall of the barrel 1. A circular hole is opened on the top cover 2, and a feed hopper 3 is bolted to the circular hole. A fixed platform 5 is bolted to the outside of the barrel 1. A quantitative addition module 6 is set on the fixed platform 5. A replacement and replenishment module 7 is set below the fixed platform 5. A mixing tank 9 is set inside the barrel 1. A uniform stirring module 8 is set inside the mixing tank 9. A protective cover 4 is bolted to the upper side of the top cover 2. A fine hole is opened on the outside of the barrel 1. A discharge pipe 10 is bolted to the fine hole. One end of the discharge pipe 10 is located inside the mixing tank 9, and the other end is located outside the barrel 1.

[0033] Specifically, after adding tungsten ore into the mixing tank 9 through the feed hopper 3, the additive is added to the mixing tank 9 using the quantitative addition module 6 and mixed with the tungsten ore. The mixture is then stirred using the uniform stirring module 8. After forming the flotation feed, the feed is extracted to the outside of the tank 1 through the discharge pipe 10. The preparation of the roughing feed is repeated according to the above steps. When the additive on the quantitative addition module 6 is about to be consumed, the additive is replenished in time using the replacement and replenishment module 7. The device can replenish the additive in time after adding tungsten ore into the mixing tank 9 using the quantitative addition module 6, reducing equipment downtime, keeping the entire preparation process continuous, ensuring the smoothness of the preparation, and improving the efficiency of the equipment in preparing the roughing feed.

[0034] Reference Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the quantitative addition module 6 includes a mounting platform 601. The mounting platform 601 is bolted to the side opposite to the fixed platform 5. A receiving box 602 is bolted to the upper side of the mounting platform 601. A circular slot 604 is provided on the receiving box 602. A rotating cylinder 605 is rotatably connected to the inner wall of the circular slot 604 via a bearing. Both the outer side of the rotating cylinder 605 and the inner wall of the circular slot 604 have discharge ports 606. A conveying pipe 607 is bolted to the inner wall of the discharge port 606 on the circular slot 604. The end of the conveying pipe 607 away from the circular slot 604 passes through the outside of the tank body 1 and is located in the mixing tank. Above the 9, and on the upper side of the receiving box 602, a slot is provided, and a storage cylinder 603 is bolted into the slot; the inner wall of the rotating cylinder 605 has two circumferentially equidistant sliding grooves 608, and the same rotating component 609 is slidably connected in the two sliding grooves 608; the outside of the rotating cylinder 605 has an inlet 614, and the outside of the rotating component 609 has a beveled groove 613, which is located on the same plane as the inlet 614; on the side of the rotating cylinder 605 away from the fixed platform 5, two circumferentially equidistant cutting grooves 610 are provided, and a stop block 611 is slidably connected in each cutting groove 610; the stop block 611 is connected to the rotating component 609. On opposite sides, the stop block 611 and the inner wall of the groove 610 are bolted together with springs 612. The rotating part 609 is bolted to the outside with an external toothed ring 615. A vertical groove 616 is formed on the outside of the barrel 1, and a connecting rod 619 is slidably connected within the groove 616. A rack 620 is bolted to the upper side of the connecting rod 619, and the rack 620 meshes with the external toothed ring 615. A top block 618 is bolted to the upper side of the mixing barrel 9, and the upper side of the top block 618 fits against the bottom of the connecting rod 619. A rectangular groove 621 is formed on the inner wall of the bottom of the barrel 1, and two... Two symmetrical movable blocks 622 are connected to each other via bearings. Push rods 623 are rotatably connected to the upper side of each movable block 622. Stabilizing plates 624 are rotatably connected to the ends of the push rods 623 away from the movable blocks 622 via bearings. The upper side of the stabilizing plates 624 is bolted to the bottom of the mixing tank 9. Four circumferentially distributed fixing rods 617 are bolted to the outside of the stabilizing plates 624. The outside of the fixing rods 617 are all in contact with the outside of the mixing tank 9. Two connecting plates 625 are bolted to the outside of each movable block 622. Springs 626 are bolted to the opposite side of the two connecting plates 625 located on the same side.

[0035] Specifically, after the tungsten ore and additives in the mixing tank 9 are stirred to form a coarse feed, the discharge pipe 10 draws the coarse feed from the mixing tank 9 out of the tank body 1. The weight of the mixing tank 9 decreases, causing the spring 626 to pull the movable block 622 in the rectangular groove 621 towards the center. This causes the mixing tank 9 to gradually rise under the push of the push rod 623. The top block 618 on the rising mixing tank 9 contacts the connecting rod 619 and pushes the connecting rod 619 to rise and move on the vertical groove 616, thereby causing the rack 6 connected to the connecting rod 619 to move upward. The gear 60 rotates in engagement with the outer gear ring 615, causing the rotating cylinder 605 on the receiving box 602 to drive the rotating component 609 to connect the oblique groove 613 with the discharge port 606. This allows the additive in the receiving box 602 to be transported into the mixing tank 9 through the conveying pipe 607 to mix with the tungsten ore. After a certain amount of additive is added, the increased weight causes the mixing tank 9 to descend again, causing the rack 620 to drive the outer gear ring 615 to rotate. This causes the rotating cylinder 605 to close the discharge port 606 and the passage between the discharge port 606, preventing the additive from flowing into the mixing tank 9.

[0036] In specific application scenarios, the quantitative addition module 6 is mainly applicable to the quantitative addition stage in the quantitative addition process. That is, the quantitative addition module 6 uses the rotating part 609 and the rotating cylinder 605 to enable the device to automatically deliver a quantitative amount of additive according to the amount of tungsten ore added after the quantitative amount of tungsten ore has been added. While ensuring the continuity of the process, it reduces the excessive addition of additives, reduces the waste of resources, and improves economic efficiency.

[0037] Reference Figure 6In a preferred embodiment, the replacement and replenishment module 7 includes a fixing frame 701, which is located outside the barrel 1. A support plate 702 is provided on the fixing frame 701. A fitting frame 703 is bolted to the upper side of the support plate 702. A replenishment box 704 is provided inside the fitting frame 703. The bottom of the replenishment box 704 is fitted to the upper side of the support plate 702. A circular hole is opened on the upper side of the replenishment box 704, and an extraction tube 705 is slidably connected in the circular hole. A connecting frame 706 is bolted to the outside of the extraction tube 705. The side of the connecting frame 706 opposite to the barrel 1 is bolted. A pump 707 is bolted to the upper side of the connecting frame 706. The output end of the pump 707 is connected to the extraction tube 705 through a conduit. The extraction tube 705 is connected to the upper side of the storage cylinder 603 via a flange at one end away from the replenishment box 704; the side of the bonding frame 703 away from the replenishment box 704 is bolted to a boss 708, a shaft 709 is slidably connected inside the boss 708, and the upper and lower sides of the shaft 709 are bolted to the outside of the fixing frame 701; the upper side of the fixing frame 701 has a groove, and a lead screw 711 is rotatably connected inside the groove via a bearing; a boss 710 is provided on the outside of the lead screw 711, and the side of the boss 710 opposite to the bonding frame 703 is bolted to it; and a motor 712 is bolted to the upper side of the fixing frame 701, and the output end of the motor 712 is connected to the upper side of the lead screw 711 via a coupling.

[0038] Specifically, after the additives stored in storage cylinder 603 are consumed, pump 707 is started. Pump 707 delivers the additives from replenishment box 704 into storage cylinder 603 through extraction tube 705. After the additives in replenishment box 704 are consumed after the usage period, motor 712 is started. Motor 712 drives screw 711 to rotate, causing boss 710 to lower bonding frame 703 and support plate 702 to the bottom of fixed frame 701, thereby pulling the bottom end of extraction tube 705 out of replenishment box 704, removing the empty replenishment box 704, placing a new replenishment box 704 on support plate 702 and bonding box 704 with bonding frame 703, starting motor 712, causing support plate 702 to lift replenishment box 704, thereby re-inserting extraction tube 705 into replenishment box 704, continuing to deliver the additives from replenishment box 704 into storage cylinder 603.

[0039] In specific application scenarios, the replacement and replenishment module 7 is mainly applicable to the replacement and replenishment stage in the replacement and replenishment process. That is, the replacement and replenishment module 7 can quickly replace the replenishment box 704 using the lead screw 711 and the support plate 702, reducing the workload of the staff and enabling the device to obtain the additives continuously, reducing interference with the device preparation process.

[0040] Reference Figure 7In a preferred embodiment, the uniform stirring module 8 includes a main shaft 801. A slot is formed on the upper side of the top cover 2. The inner wall of the slot is rotatably connected to the outside of the main shaft 801 via bearings. Four symmetrical crossbars 802 are bolted to the outside of the main shaft 801. A secondary shaft 803 is rotatably connected to two crossbars 802 on the same side via bearings. Gears 804 are bolted to the outside of each secondary shaft 803. The gears 804 are all located on the upper side of the crossbars 802. Three circumferentially equidistant positioning plates 805 are bolted to the bottom of the top cover 2. The bottom of each of the two secondary shafts 805 is bolted to the same internal gear ring 806. Both gears 804 mesh with the internal gear ring 806. The exterior of each of the two secondary shafts 803 is bolted to two symmetrical crossbars 807. On the opposite side of each of the two crossbars 807 on the same secondary shaft 803, there are two symmetrical round rods 808 bolted to each other. The exterior of each of the two round rods 808 is bolted to multiple equidistant stirring rods 809. The top inner wall of the protective cover 4 is bolted to a motor 810. The output end of the motor 810 is connected to the upper side of the main shaft 801 via a coupling.

[0041] Specifically, after loading tungsten ore and additives into mixing tank 9, motor 2 810 is started. Motor 2 810 drives the crossbar 1 802 on the main shaft 801 to rotate, so that the gear 804 on the crossbar 1 802, which is connected to the secondary shaft 803, can mesh with the internal gear ring 806 to rotate. This causes the secondary shaft 803 to drive the crossbar 2 807 to rotate, so that the stirring rod 809 on the round rod 808 stirs and agitates the tungsten ore and additives in mixing tank 9.

[0042] In specific application scenarios, the uniform stirring module 8 is mainly suitable for the uniform stirring stage in the uniform stirring process. That is, the uniform stirring module 8 uses gear 804 and internal gear ring 806 to make the secondary shaft 803 rotate around the main shaft 801 while driving the round rod 808 to rotate around itself, which enhances the stirring effect of the device, allows the tungsten ore to fully contact the additives, ensures the stirring effect, and improves the efficiency of preparing roughing feed.

[0043] Working principle: After the tungsten ore and additives are added to the mixing tank 9, the second motor 810 is started. The second motor 810 drives the crossbar 802 on the main shaft 801 to rotate, so that the gear 804 on the crossbar 802, which is connected to the secondary shaft 803, can mesh with the internal gear ring 806 to rotate. This causes the secondary shaft 803 to drive the second crossbar 807 to rotate, so that the stirring rod 809 on the round rod 808 stirs and agitates the tungsten ore and additives in the mixing tank 9. After the coarse feed is formed, the discharge pipe 10 draws the coarse feed from the mixing tank 9 out of the tank body 1, reducing the weight of the mixing tank 9. This causes the spring 626 to pull the movable block 622 in the rectangular groove 621 towards the center, causing the mixing tank 9 to gradually rise under the push of the push rod 623. The top block 618 on the rising mixing tank 9, after contacting the connecting rod 619, pushes the connecting rod 619 to move upwards on the vertical groove 616, thereby causing the rack 620 connected to the connecting rod 619 to mesh and rotate with the outer gear ring 615. This causes the rotating cylinder 605 on the receiving box 602 to drive the rotating component 609 to connect the oblique groove 613 with the discharge port 606, allowing the additive in the receiving box 602 to be conveyed into the mixing tank through the conveying pipe 607. Mixing drum 9 with tungsten ore, after adding a certain amount of additive, the increased weight causes mixing drum 9 to descend again, causing rack 620 to drive external gear ring 615 to rotate, causing rotating drum 605 to close the discharge port 606 and the channel between the discharge port 606 and the discharge port 606, preventing the additive from flowing into mixing drum 9. After the additive stored in storage drum 603 is consumed, pump 707 is started. Pump 707 transports the additive in replenishment tank 704 into storage drum 603 through extraction pipe 705. After the usage time, after the additive in replenishment tank 704 is consumed, motor 712 is started. Motor 712 drives screw 711 to rotate, causing boss 710 to lower bonding frame 703 and support plate 702 to the bottom of fixed frame 701, thereby pulling the bottom end of extraction tube 705 out of replenishment box 704, taking out empty replenishment box 704, placing new replenishment box 704 on support plate 702 and making replenishment box 704 fit with bonding frame 703, starting motor 712, causing support plate 702 to lift replenishment box 704, thereby causing extraction tube 705 to be reinserted into replenishment box 704, continuing to deliver additive in replenishment box 704 into storage cylinder 603.
