Description

Technical Field

[0001] This invention belongs to the technical field of slag separation equipment, and particularly relates to a filtration device that can quickly separate the acid-soluble phase and the residual phase in ore. Background Technology

[0002] Ore separation is a core step in mineral processing. It refers to the process of separating valuable minerals from gangue minerals, or separating various symbiotic valuable minerals, based on the differences in the physical and chemical properties of different minerals in the ore, using mechanical, instrumental, or reagent means. The aim is to enrich the target minerals, remove impurities, and provide raw materials for subsequent processing.

[0003] Existing ore separation methods mainly include physical and chemical methods, especially for ores containing acid-soluble phases. When separating such ores, it is necessary to separate the acid-soluble phase from the residual phase. Utilizing the chemical characteristic that the residual phase is insoluble in acid, the acid-soluble phase is dissolved in the acid solution, facilitating subsequent extraction. While existing technologies possess well-developed systems and methods for this type of separation and filtration, the following key shortcomings still exist: 1. Long working cycle: After the ore is mined and crushed, it is still in large particles and cannot fully contact and dissolve with acid. The acid leaching time needs to be extended to complete the precipitation of the acid-soluble phase, which significantly increases the overall processing cycle.

[0004] 2. Lack of continuity in ore transfer and separation steps: In the existing technology, ore transfer and separation are independent processes that require the use of multiple sets of equipment. The pre-treated and crushed ore must first be transferred to the screening mechanism before it can be dissolved, resulting in a lack of continuity in the work and further reducing efficiency.

[0005] 3. High energy consumption: Because multiple independent mechanical equipment are required for processing, the independent operation of multiple systems leads to a significant increase in energy consumption, and the large number of components results in high maintenance costs.

[0006] To address the aforementioned issues, a filtration device is proposed that can rapidly separate the acid-soluble phase and the residual phase in ore. Summary of the Invention

Sliding sleeves are slidably fitted on the two second links, and the sliding sleeves are hinged to the third links at the corresponding positions.

[0009] A further technical solution is as follows: the filter assembly includes a first semi-circular barrel and a second semi-circular barrel; the movable plate is connected to the first semi-circular barrel, a base is provided at the bottom of the first semi-circular barrel, a second semi-circular barrel is detachably provided on the rear side of the first semi-circular barrel, the second semi-circular barrel is movably provided on the upper end of the base, and the outer walls of the first semi-circular barrel and the second semi-circular barrel are provided with a plurality of liquid inlet holes.

[0010] A further technical solution is as follows: the reciprocating mechanism includes a reciprocating screw, a first transmission wheel, a second transmission wheel, and a transmission belt; the reciprocating screw is located below the connecting plate and is rotatably connected to the connecting plate; the reciprocating screw passes through the movable plate and is threadedly connected to the movable plate; the lower end of the reciprocating screw passes through the top wall of the mounting box and is rotatably connected to the mounting box; the lower end of the reciprocating screw is provided with the first transmission wheel; the first transmission wheel is connected to the second transmission wheel via a transmission belt; and the second transmission wheel is connected to the drive device.

[0011] A further technical solution is as follows: the grinding mechanism includes a conical roller, a conical cylinder, an annular base, a main shaft, and a motor; the upper end of the movable base plate is provided with a motor, and the first end of the main shaft is fixedly provided on the output shaft of the motor; the second end of the main shaft is rotatably connected to the top wall of the mounting box and the bottom wall of the acid tank respectively; the main shaft and the base are movably connected; the second transmission wheel is fixedly sleeved on the outer wall of the main shaft; the main shaft and the bottom wall of the acid tank are sealed and rotatably connected; the top of the second end of the main shaft is provided with a conical roller; the second end of the connecting plate is provided with an annular base, and the upper end of the annular base is connected to a conical cylinder; the conical roller is rotatably located inside the conical cylinder; a discharge gap is left between the upper part of the lower end of the conical roller and the inner wall of the annular base.

[0012] A further technical solution is that: a plurality of stirring blades are fixedly sleeved on the outer wall of the main shaft, and the plurality of stirring blades are movably disposed inside the acid tank, and the chassis is movably disposed above the plurality of stirring blades.

[0016] A further technical solution is that connecting columns are provided on both sides of the movable plate, and the first connecting rod is rotatably connected to the connecting columns.

[0017] (3) Due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Work cycle significantly reduced This invention utilizes a fine grinding mechanism to further refine the crushed ore, significantly reducing its particle size and increasing its specific surface area. This allows for full contact and rapid dissolution with acid, greatly shortening the acid leaching reaction time and effectively solving the problems of insufficient dissolution and long processing cycles caused by excessively large ore particles.

[0018] 2. The pretreatment and separation steps are performed simultaneously, significantly improving workflow smoothness. This invention utilizes the linkage between the excavation and transportation mechanisms to directly excavate, rapidly transport, and precisely deliver the crushed ore to the fine grinding mechanism, eliminating intermediate transportation links. After being finely ground by conical rollers and conical cylinders, the ore falls directly into the filtration assembly by gravity. Subsequently, driven by a reciprocating mechanism, it is periodically immersed in an acid tank to complete acid dissolution and filtration. This completes a continuous closed-loop operation of the entire process of excavation, transportation, fine grinding, acid leaching, and separation, fundamentally solving the problem of poor coordination and significantly improving the overall smoothness of the operation.

[0019] 3. Reduced energy consumption and easier maintenance This invention replaces the complexity of multiple systems and equipment operating in sequence in the prior art by controlling the reciprocating motion of the filter components, the crushing of the fine grinding mechanism, and the complex digging and transportation work with a single motor linkage control. This reduces the number of parts, lowers energy consumption and maintenance costs, and improves the economic efficiency of equipment operation. Attached Figure Description

In the description of the invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0023] refer to Figures 1 to 10 A filter device for rapidly separating acid-soluble phase and residual phase in ore includes a movable base plate 1, a mounting box 3, an acid tank 4, a connecting plate 6, a support rod 602, a bucket 18, a filter assembly, a reciprocating mechanism, a grinding mechanism, a conveying mechanism, and a digging mechanism. A mounting box 3 is installed on the upper end of the movable base plate 1. A connecting plate 6 is fixedly installed on the top wall of the mounting box 3 via a support rod 602. A grinding mechanism is installed on the right side of the connecting plate 6. The movable base plate 1 has a certain mobility, which enhances the flexibility of the equipment. It is also used to fix the mounting box 3. The mounting box 3 is used to support the acid tank 4 described later and the connecting plate 6 fixedly installed via the support rod 602. The mounting box 3, the support rod 602, and the connecting plate 6 fixedly installed with the base plate 1 are the basic components of this equipment and mainly play a supporting role. An acid tank 4 is installed on the rear side of the support rod 602. The acid tank 4 is installed on the upper end of the mounting box 3. A filter assembly is movably installed inside the acid tank 4. The filter assembly is driven to move by a reciprocating mechanism. The acid tank 4 contains an acidic solution for chemical reaction, which facilitates the precipitation of acid-soluble substances in the ore. The filter assembly is used to hold the ore after initial pretreatment and crushing, as well as the residual phase remaining after soaking in the acidic solution. The reciprocating mechanism is driven by the grinding mechanism, which allows the filter assembly to move up and down, enabling it to be periodically or intermittently immersed in the acid tank 4. An output pipe 5 is installed at the bottom of the front wall of the acid tank 4. A valve is installed inside the output pipe 5. After the valve is opened, the acidic solution and the acid-soluble phase substances that have been dissolved in the solution can be released from the output pipe 5. The mounting box 3 is equipped with a conveying mechanism on both sides; A bucket 18 is movably installed on the rear side of the acid tank 4. The bucket 18 is driven by a conveying mechanism, which allows the bucket 18 to move back and forth between two points: the ore pile to be excavated and the top of the grinding mechanism, thereby achieving the transportation function. The bucket 18 is driven to rotate by the digging mechanism. The digging mechanism, in conjunction with the transport mechanism, allows the bucket 18 to be in a ready-to-dig state when it is close to the ore pile. When it is located above the grinding mechanism, it can dig and deliver the ore by rotating upwards. The bucket 18 is detachably mounted above the grinding mechanism.

[0024] The filter assembly includes a first semi-circular barrel 9, a second semi-circular barrel 10, a movable plate 8, and a chassis; The middle end of the movable plate 8 is slidably installed on the outer wall of the support rod 602. The rear end of the movable plate 8 is equipped with a first semi-circular barrel 9. The bottom wall of the first semi-circular barrel 9 is equipped with a chassis. The rear side of the first semi-circular barrel 9 is detachably equipped with a second semi-circular barrel 10. The second semi-circular barrel 10 is movably installed on the upper end of the chassis. The first semi-circular barrel 9, the second semi-circular barrel 10, and the chassis can all be detached and movable inside the acid tank 4; The outer walls of the first semi-circular barrel 9 and the second semi-circular barrel 10 are each provided with several liquid inlet holes; The movable plate 8 is driven to move by the reciprocating mechanism; The movable plate 8 operates through a movable drive conveying mechanism. The filter assembly is a cylindrical structure composed of a first semi-circular barrel 9 and a second semi-circular barrel 10, both of which are blocked by a chassis at their bottom. When the filter assembly is in operation, the first semi-circular barrel 9 and the second semi-circular barrel 10 are fixed together by a latch or other means of temporarily fixing the two parts (such as buckles, quick-release pins, hinges, etc., which are common and mature structures in existing mechanical equipment). When it is necessary to remove the residue inside the assembly, the second semi-circular barrel 10 can be separated simply by opening the latch. It should be noted that the up-and-down movement of the filter assembly depends on the up-and-down movement of the movable plate 8. When the movable plate 8 moves down to the bottom, it should not interfere with the top wall of the acid tank 4. The limit distance of the downward movement of the movable plate 8 should be limited. As a preferred embodiment of the present invention, the output pipe 5 on the acid tank 4 is equipped with a filter screen, which can further filter the residue inside the tank.

[0025] The reciprocating mechanism includes a reciprocating lead screw 7, a first transmission wheel 2301, a second transmission wheel 23, and a transmission belt 24; A reciprocating lead screw 7 is installed on the front side of the support rod 602; The reciprocating screw 7 and the front end of the movable plate 8 are threaded through each other. The upper end of the reciprocating screw 7 is rotatably installed at the lower part of the first end of the connecting plate 6. The lower end of the reciprocating screw 7 is rotatably installed through the top wall of the mounting box 3 and a first transmission wheel 2301 is installed. A second transmission wheel 23 is installed on the rear side of the first transmission wheel 2301. The second transmission wheel 23 is rotatably installed at the lower end of the top wall of the mounting box 3. The same transmission belt 24 is installed on the outer side of the first transmission wheel 2301 and the second transmission wheel 23; The second transmission wheel 23 is driven to rotate by the grinding mechanism. Under the drive of the grinding mechanism, the second transmission wheel 23 starts to rotate and drives the first transmission wheel 2301 to start rotating through the transmission belt 24. The first transmission wheel 2301 can drive the reciprocating screw 7 to start rotating by rotating. During the rotation of the reciprocating screw 7, it can drive the movable plate 8, which is threaded through it, to move up and down. Since the movement trajectory of the movable plate 8 is limited by the support rod 602, the movable plate 8 can only move up and down and will not rotate. The movable plate 8 can drive the first semi-circular barrel 9 to move up and down by moving up and down, and thus drive the entire filter assembly to move up and down. Preferably, the limit distance of the up and down movement of the movable plate 8 can be limited by the lead of the reciprocating screw.

[0026] The grinding mechanism includes a conical roller 17, a conical cylinder 16, an annular base 601, a main shaft 1701, and a motor 22; A motor 22 is installed on the upper end of the movable base plate 1. The first end of the main shaft 1701 is fixedly installed on the output shaft of the motor 22. The second end of the main shaft 1701 is rotatably connected between the top wall of the mounting box 3 and the bottom wall of the acid tank 4. The spindle 1701 and the chassis are connected in a movable manner; The second transmission wheel 23 is fixedly installed on the outer wall of the main shaft 1701; A sealed, rotating through-type structure is installed between the main shaft 1701 and the bottom wall of the acid tank 4; A tapered roller 17 is mounted on the top of the second end of the main shaft 1701; An annular base 601 is installed at the second end of the connecting plate 6, and a conical cylinder 16 is connected to the upper end of the annular base 601. The conical roller 17 is rotatably mounted on the inner side of the conical cylinder 16; A discharge gap is left between the upper part of the lower end of the conical roller 17 and the inner wall of the annular base 601, for reference. Figure 8 After the motor 22 is started, its output shaft begins to rotate, which in turn drives the conical roller 17, which is fixedly mounted on the same axis, to rotate. (Refer to...) Figure 4The ore transported by the bucket 18 enters the conical cylinder 16 from above and moves downwards under the influence of gravity. Because the conical roller 17 and the conical cylinder 16 form a conical cavity that is wider at the top and narrower at the bottom, the ore is gradually squeezed and refined from top to bottom. As the conical roller 17 rotates, the ore is rubbed, sheared, and squeezed between the conical surfaces. Larger ore particles are squeezed and extruded downwards through the discharge gap as the conical roller 17 rotates, eventually being crushed into smaller ore fragments that enter the filter assembly. The smaller fragments facilitate thorough mixing with the acidic solution in the acid tank 4.

[0027] Several stirring blades 25 are fixedly installed on the outer wall of the main shaft 1701. The stirring blades 25 are movably installed inside the acid tank 4. The chassis is movably installed above the stirring blades 25. The stirring blades 25 are extension components of the main shaft 1701 and can rotate synchronously with the main shaft 1701. The purpose is to stir the acidic solution in the acid tank 4 so that it can be fully mixed with the slag.

[0028] The conveying mechanism includes a connecting column 801, a first connecting rod 20, a second connecting rod 11, and a rotating shaft 19; The first ends of connecting posts 801 are respectively installed on the front of both sides of the movable plate 8, and the first ends of the first connecting rod 20 are respectively rotatably installed on the second ends of the two connecting posts 801. The left and right side walls of the mounting box 3 are respectively equipped with first fixed shafts, and the first ends of the second connecting rods 11 are respectively rotatably installed on the outer walls of the two first fixed shafts. A second fixed shaft is installed on the upper outer wall of the first end of each of the two second connecting rods 11, and the second ends of the two first connecting rods 20 are rotatably installed on the outer wall of the second fixed shaft that is close to them. The two second connecting rods 11 are rotatably connected to the same rotating shaft 19 at their second ends. A connecting block 1801 is installed on the rear wall of the bucket 18, and the connecting block 1801 is fixedly installed at the middle end of the rotating shaft 19. The two second linkages 11 drive the excavation mechanism to work through rotation, as shown in the reference. Figure 3 When the movable plate 8 moves from bottom to top, the filter assembly gradually approaches the discharge gap. At this time, the first connecting rods 20 on both sides begin to deflect upward. During the upward deflection of the two first connecting rods 20, they respectively pull the second connecting rods 11 on both sides to start rotating upward around their own rotation center. The rotating shaft 19 can then carry the bucket 18 upward to put the excavated ore into the conical cylinder 16. Conversely, when the movable plate 8 moves from top to bottom, the two second connecting rods 11 begin to rotate downward and drive the bucket downward through the rotating shaft 19, eventually approaching the ore pile. Driven by the excavation mechanism described later, the bucket 18 begins to rotate, so that the bucket 18 digs up the ore during the next upward movement.

[0029] The excavation mechanism includes a sliding sleeve 13, a third link 14, a fourth link 15, a sliding rod 12, and an extension plate 2; Sliding sleeves 13 are slidably installed on the outer walls of the two second connecting rods 11 respectively, and the two sliding sleeves 13 are movably installed on the right side of the first connecting rod 20 that is close to them; A third fixed shaft is installed on the outer wall of each of the two sliding sleeves 13, and the first end of the third connecting rod 14 is rotatably installed on the outer wall of each of the two third fixed shafts. The first ends of the fourth connecting rods 15 are fixedly installed at both ends of the rotating shaft 19, and the second ends of the two fourth connecting rods 15 are respectively installed on the outer walls of the second ends of the fourth connecting rods 15. The second ends of the two third connecting rods 14 are respectively rotatably installed on the outer walls of the fourth fixed shafts that are close to them. An extension plate 2 is installed on both sides of the rear end of the movable base plate 1. The first end of the sliding rod 12 is slidably installed on the upper end of the two extension plates 2 respectively. The lower end of the two sliding rods 12 is installed with a T-shaped slider. T-shaped grooves that cooperate with the T-shaped sliders are opened on the two extension plates 2. The sliding rods 12 and the extension plates 2 slide through the cooperation between the T-shaped sliders and the T-shaped grooves to ensure that they do not move during the sliding process. The second ends of the two sliding rods 12 are respectively rotatably mounted on the outer wall of the third fixed shaft that is close to them; Two third links 14 are respectively movably mounted between the adjacent sliding sleeve 13 and sliding rod 12, for reference. Figure 3 When the movable plate 8 moves downward, it drives the two second connecting rods 11 to rotate downward through the two first connecting rods 20. Simultaneously, the two sliding rods 12 begin to slide to the right along the adjacent extension plate 2. While sliding to the right, the two sliding rods 12 also drive the adjacent sliding sleeves 13 to slide to the right along the outer wall of the cooperating second connecting rods 11. As the two sliding sleeves 13 slide to the right, they also drive the two third connecting rods 14 to deflect upward. When the two third connecting rods 14 deflect upward, they push the two fourth connecting rods 15 to rotate clockwise. At this point, the rotating shaft 19, fixedly installed with the two fourth connecting rods 15, can start to drive the bucket to rotate clockwise. When the movable plate 8 moves downward to its limit position, it is in a state as follows... Figure 10 As shown in Figure A, the bucket is in the ready-to-dig state. As the movable plate 8 moves upward, the two second connecting rods 11 begin to rotate upward, pulling the two sliding rods 12 to slide to the left. Simultaneously, the sliding rods 12 pull the adjacent sliding sleeves 13 to slide to the left along the cooperating second connecting rods 11. At this time, the two sliding sleeves 13 pull the two third connecting rods 14 downward, and the two fourth connecting rods 15 begin to rotate counterclockwise. After digging is complete... Figure 10In the state shown in B, as the movable plate 8 continues to move upward, the rotating shaft 19 will drive the bucket 18 to rotate further counterclockwise until the bucket 18 moves above the conical cylinder 16. At this point, the bucket 18 rotates counterclockwise to its limit position, and the excavated ore can be dumped.

[0030] The lower end of the movable base plate 1 is equipped with a mobile support device. The mobile support device is only used to support the base plate 1 for movement. It can be an integrated plate with universal wheels or a track mounted by a track assembly. Both are existing technologies and will not be described in detail here. With this combination, the movable base plate 1 can move during the excavation process to further embed the bucket 18 into the depth of the ore pile, so that the bucket 18 can be fully loaded in each excavation.

[0031] A ventilation plate 21 is installed on the front side of the mounting box 3. Its function is to dissipate heat from the continuously operating motor 22. It should be noted that ventilation holes are provided on the entire outer wall of the mounting box 3, which form convection air with the ventilation plate 21 to enhance the heating effect. The ventilation plate 21 is detachable, which facilitates the maintenance and repair of the internal motor.

[0032] The bottom wall of the first semi-circular barrel 9 has a slag collection groove with a certain depth to meet the collection of residue. When it rises completely away from the acid tank 4, the residue in the slag collection groove can be collected in a concentrated manner when the second semi-circular barrel 8 is opened.

[0033] Implementation method of the present invention: The movable base plate 1 is moved to one side of the ore pile via a moving process device. An acidic solution is injected into the acid tank 4. The motor 22 is started, and the bucket 18 begins to move towards the already crushed ore pile. The ore pile is excavated into the bucket 18 and moved above the conical cylinder 16 via the rotation of the two second connecting rods 11. During this process, the bucket sequentially performs the following... Figure 10 A- Figure 10 The process of B; After the excavated ore is fed into the conical cylinder 16 by the bucket 18, the ore will be ground into slag with smaller particle size and easy to dissolve in acidic solution as the conical roller 17 continues to rotate. The slag will fall down from the discharge gap and be collected by the filter assembly. During this process, the bucket 18 moves closer to the ore pile and prepares for the next excavation. As the motor 22 continues to rotate, the filter assembly that collects the slag slides downward and is completely immersed in the acid tank 4. The acidic solution in the acid tank 4 is dissolved with the slag inside through several inlet holes on the filter assembly. Since several stirring blades 25 are rotating throughout this cycle, the acidic solution in the acid tank 4 is dynamic, which further accelerates the dissolution with the slag.

[0034] At this point, motor 22 can be stopped for a period of time. This step is mainly to increase the contact time between the acid solution and the slag. The actual stopping time can be determined according to the on-site working conditions. After a period of time, motor 22 will continue to work until the filter assembly is fully lifted and receives the next batch of ore from the bucket 18. The above operation can be repeated.

[0035] Before the filter assembly is fully loaded with residual phase, the movable base plate 1 can be moved away from the ore pile in advance. After the filter assembly is completely protruding from the acid tank 4, the motor 22 is stopped and the second semi-circular tank 10 is removed to collect the residual phase inside. The acid-soluble phase has been dissolved in the acid tank 4, and it can be released by simply opening the valve on the acid tank 4.

[0036] This invention utilizes the convenience of a movable chassis, allowing operation directly in front of piled-up, crushed ore hills. With the excavation of the bucket, the target ore is directly transported to the grinding mechanism, eliminating the need for ore transport and transfer steps, significantly reducing the work cycle. Utilizing the principle of gravity, the crushed ore is further ground in the grinding mechanism under gravity, then directly transferred to the filter assembly. The up-and-down movement of the filter assembly allows it to periodically immerse itself in the acid tank, achieving continuous separation of the acid-soluble phase and the residual phase. This significantly improves operational smoothness. By using a single motor to control the reciprocating motion of the filter assembly, the crushing of the grinding mechanism, and the complex excavation and transport operations, this invention replaces the complexity of multiple systems and equipment operating sequentially in existing technologies. It reduces the number of components, lowers energy consumption and maintenance costs, and improves the economic efficiency of equipment operation.

[0037] The above are merely preferred embodiments of the present invention.
