Description

Technical Field

[0001] This invention relates to the technical field of mineral processing, and in particular to a multi-stage pre-flow equalization and graded optimization integrated device. Background Technology

[0002] The mineral processing industry is an important part of modern industry. It involves the mining, crushing, grading and refining of various metallic and non-metallic minerals, providing basic raw materials for multiple fields such as construction, chemical industry, electronics and energy. With the continuous growth of global resource demand and technological progress, the mineral processing industry faces major challenges in improving production efficiency, reducing energy consumption, reducing environmental impact and improving product quality.

[0003] Traditional mineral crushing involves directly feeding large minerals into a crusher for preliminary crushing, followed by grinding in a mill to obtain powder of a specified mesh size. However, the minerals are not homogenized or classified before grinding. This leads to problems such as uneven material distribution, high energy consumption, severe equipment wear, and poor particle size control during material processing. These problems not only increase production costs but also limit the market competitiveness of mineral products. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a multi-stage pre-flow equalization and hierarchical optimization integration device, the specific technical solution of which is as follows:

[0005] A multi-stage pre-flow equalization and graded optimization integrated device includes a vertically inclined equalization trough for conveying materials. The equalization trough is equipped with multiple sets of flow equalization structures, which are arranged along the length of the equalization trough. The distance between the multiple sets of flow equalization structures and the bottom surface of the equalization trough gradually changes along the length of the flow equalization structure. The flow equalization structure consists of a rotating drum and multiple material feeding frames arranged on the rotating drum. The rotating drum is rotatably mounted on the equalization trough, and the multiple material feeding frames are arranged in a ring on the rotating drum. The shortest distance between the material feeding frames and the bottom surface of the equalization trough is a specified distance that allows materials to pass through.

[0006] Among them, except for the group of flow equalization structures at the bottom of the flow equalization trough, each of the multiple flow equalization structures is equipped with a distribution trough. The distribution trough is inclined on the vertical plane. Each distribution trough and the bottom surface of the flow equalization trough between two adjacent groups of flow equalization structures are equipped with a vibration mechanism. The vibration mechanism includes multiple flow equalization plates, which are arranged in a straight line. The flow equalization plates are horizontal and their length direction is perpendicular to the conveying direction of the material on the flow equalization trough. The flow equalization plates reciprocate on the flow equalization trough or the distribution trough along their length direction. The cross-sectional shape of the flow equalization plates is triangular.

[0007] Furthermore, the feeding frame consists of multiple insert rods and a connecting rod. The multiple insert rods are arranged along the axis of the rotating drum, and the length direction of the insert rods is along the radial direction of the rotating drum. One end of the insert rod is inserted into the rotating drum, and the connecting rod is installed at the other end of the multiple insert rods. The length direction of the connecting rod is parallel to the axis of the rotating drum.

[0008] Furthermore, the insertion rod slides along the length of the insertion rod on the rotating drum;

[0009] The rotating drum is provided with a guide structure, which is used to make the connecting rod move along the length of the material equalization trough after it has moved to a specified distance close to the material equalization trough.

[0010] Furthermore, a mandrel is coaxially inserted in the middle of the rotating drum, and multiple connecting plates are provided on the outer wall of the mandrel. The connecting plates are fixed on the inner wall of the rotating drum, and the insertion rod is slidably installed on the surface of the connecting plates.

[0011] The guide structure includes two fixed discs installed at both ends of the rotating drum, and the rotating drum rotates on the fixed discs. The spindle passes through the fixed discs and rotates relative to them. A guide groove is provided on the fixed disc, which is composed of a first arc groove and a second arc groove. Among the multiple inserts on the feeding frame, two inserts located at both ends of the connecting rod are provided with sliding columns, which are slidably installed in the guide groove.

[0012] When the sliding column slides in the first arc groove, the insert rod rotates synchronously with the rotating drum, and the insert rod and the rotating drum remain relatively stationary. When the sliding column slides in the second arc groove, the insert rod slides on the rotating drum.

[0013] Furthermore, multiple sliding openings are provided on the front and rear side walls of the material leveling trough. The length direction of the sliding opening is perpendicular to the material leveling trough in the vertical plane. A first slider is slidably arranged in the sliding opening. The mandrel passes through the first slider and is rotatably connected to it. A worm gear is provided on the mandrel.

[0014] The front and rear side walls of the material leveling trough are each equipped with a worm gear and a first motor. The first motor provides power to the worm gear, and the worm gear meshes with multiple worm wheels on the side wall of the material leveling trough.

[0015] The fixed plate is fixed on the first slider.

[0016] Furthermore, the mandrel end is connected to the worm gear via a connecting frame, one end of the worm gear is rotatably mounted on the side wall of the material leveling trough via a support shaft, the first motor is mounted on the other end of the worm gear, and the first motor is connected to the material leveling trough via an adjusting cylinder.

[0017] Furthermore, a second slider is slidably disposed on the side wall of the material distribution trough. The second slider is connected to the material equalization trough through a side plate, and the second slider rotates on the side plate. The material distribution trough is connected to the fixed plate through a push-pull plate.

[0018] Furthermore, the vibration mechanism also includes a second motor, the output end of which is provided with a disk, a eccentrically mounted paddle on the disk, and a long groove plate sleeved on the outer side of the paddle, the long groove plate being fixedly connected to multiple material equalization long plates on the vibration mechanism.

[0019] The length direction of the long groove plate is perpendicular to the sliding direction of the uniform material long plate.

[0020] The advantages of this invention are:

[0021] The multiple flow equalization structures in the equipment can ensure that the material is evenly distributed before entering the main crushing unit, avoiding local overload, thereby reducing equipment wear and improving crushing efficiency;

[0022] By using the gap between the flow equalization structure and the material equalization trough, materials that meet specific particle size requirements can be accurately screened out. Multiple material feeders on the flow equalization structure are used to lift and separate the intercepted materials, thereby achieving the grading and optimization of materials and ensuring the consistency and controllability of product particle size.

[0023] By utilizing multiple sets of flow equalization structures and multiple material equalization plates for multi-stage pre-flow equalization and graded optimization of materials, finer particle size control can be achieved, facilitating the individual processing of materials of different particle sizes and improving the quality and market competitiveness of the final product.

[0024] In summary, the device of the present invention, through multi-stage pre-flow equalization and classification optimization integration, can significantly improve the material handling effect in the mineral crushing and classification process, increase production efficiency, reduce energy consumption, reduce environmental pollution, and at the same time improve product quality and enhance the company's market competitiveness.

[0036] 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.

[0037] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0039] like Figures 1 to 4 As shown, the multi-stage pre-flow equalization and graded optimization integrated device of the present invention includes a vertically inclined equalization trough 1, which is used to transport materials. Multiple sets of equalization structures 2 are arranged on the equalization trough 1 along the length of the equalization trough 1, and the distance between the multiple sets of equalization structures 2 and the bottom surface of the equalization trough 1 gradually changes along the length of the equalization structure 2. The equalization structure 2 consists of a rotating drum 3 and multiple material feeding frames 4 arranged on the rotating drum 3. The rotating drum 3 is rotatably arranged on the equalization trough 1, and the multiple material feeding frames 4 are arranged in a ring on the rotating drum 3. The shortest distance between the material feeding frames 4 and the bottom surface of the equalization trough 1 is a specified distance that allows materials to pass through.

[0040] Among them, except for the group of flow equalization structures 2 at the bottom of the flow equalization trough 1, each of the multiple flow equalization structures 2 is equipped with a distribution trough 5. The distribution trough 5 is inclined on the vertical plane. Each distribution trough 5 and the bottom surface of the flow equalization trough 1 between two adjacent groups of flow equalization structures 2 are equipped with a vibration mechanism. The vibration mechanism includes multiple equalization long plates 6, which are arranged in a straight line. The equalization long plates 6 are horizontal and the length direction of the equalization long plates 6 is perpendicular to the conveying direction of the material on the flow equalization trough 1. The equalization long plates 6 reciprocate along their length direction on the flow equalization trough 1 or the distribution trough 5. The cross-sectional shape of the equalization long plate 6 is triangular.

[0041] In detail, both the equalization trough 1 and the distribution trough 5 are inclined on a vertical plane, allowing materials to slide naturally onto both troughs. The inclination angle of the equalization trough 1 is greater than that of the distribution trough 5. The distribution trough 5 is positioned on top of the equalization trough 1. The flow equalization structure 2 is used to evenly distribute the material on the equalization trough 1. Since the distance between the multiple sets of flow equalization structures 2 and the bottom surface of the equalization trough 1 gradually changes (i.e., from top to bottom, the distance between the multiple sets of flow equalization structures 2 and the bottom surface of the equalization trough 1 gradually decreases), the flow equalization structure 2 can be used to achieve step-by-step equalization of the material on the equalization trough 1. Furthermore, the multiple material pickers 4 on the flow equalization structure 2 will scoop up materials that cannot pass through the gap between the flow equalization structure 2 and the equalization trough 1 and transfer them to the distribution trough 5. The material is graded and optimized to facilitate the separate conveying of materials of different specifications. The rotating drum 3 is rotatably installed on the material leveling trough 1. The material leveling plate 6 on the vibrating mechanism can reciprocate on the material leveling trough 1 or the material distribution trough 5. The inclined surface on the material leveling plate 6 protrudes into the material leveling trough 1 or the material distribution trough 5. When the material naturally slides onto the material leveling plate 6, the inclined surface of the material leveling plate 6 will block the material. Due to the reciprocating motion of the material leveling plate 6, the material is evenly gathered on the inclined surface of the material leveling plate 6. As the amount of material increases, the material will cross the material leveling plate 6 and continue to slide on the material leveling trough 1 or the material distribution trough 5. Thus, the material leveling plate 6 is used to achieve a second flow equalization treatment of the material. Multiple material leveling plates 6 perform multiple flow equalization operations on the material.

[0042] In actual use, the material initially crushed by the crusher is introduced into the upper part of the equalization trough 1. The material slides naturally in the equalization trough 1. When the material moves to the position of the flow equalization structure 2, the rotating drum 3 is rotated. The rotating drum 3 will drive multiple material feeding frames 4 on it to rotate synchronously. The moving direction of the material feeding frames 4 on the lower side of the rotating drum 3 is opposite to the sliding direction of the material. The material feeding frames 4 on the lower side of the rotating drum 3 will intercept larger volumes of material, while smaller volumes of material will continue to slide through the gap between the material feeding frames 4 and the equalization trough 1. At this time, the flow equalization structure 2 and the equalization trough 1 can achieve the purpose of screening the material. And because the rotating drum 3 rotates... The movement of the material equalization structure 2 and the material equalization trough 1 allows the material to pass evenly through the gap, thus achieving the work of equalizing the material flow. Since the direction of movement of the material feeder 4 is opposite to the direction of material movement, the material feeder 4 can pick up the intercepted material and lift it into the corresponding material distribution trough 5. At this time, the material achieves the work of graded optimization. As the material on the material equalization trough 1 continuously passes through multiple sets of equalization structures 2, the purpose of multi-level equalization and multiple graded optimization of the material is achieved. At the same time, since the material equalization plate 6 moves back and forth on the material equalization trough 1 or the material distribution trough 5, the material equalization plate 6 can be used to achieve the work of equalizing the material flow again.

[0043] The multiple sets of flow equalization structures 2 in the equipment ensure that the material is evenly distributed before entering the main crushing unit, avoiding local overload, thereby reducing equipment wear and improving crushing efficiency. Through the gap between the flow equalization structure 2 and the material equalization trough 1, materials meeting specific particle size requirements can be precisely screened. Multiple material guides 4 on the flow equalization structure 2 lift and separate intercepted materials, achieving material grading optimization and ensuring product particle size consistency and controllability. By utilizing multiple sets of flow equalization structures 2 and multiple material equalization plates 6 for multi-stage pre-flow equalization and grading optimization, finer particle size control can be achieved, facilitating individual processing of materials of different particle sizes and improving the quality and market competitiveness of the final product. In summary, the device of this invention, through the integration of multi-stage pre-flow equalization and grading optimization, can significantly improve the material handling effect in the mineral crushing and grading process, increase production efficiency, reduce energy consumption, reduce environmental pollution, and simultaneously improve product quality and enhance the enterprise's market competitiveness.

[0044] like Figure 5 As shown, the feeding rack 4 consists of multiple insert rods 7 and a connecting rod 8. The multiple insert rods 7 are arranged along the axial direction of the rotating drum 3, and the length direction of the insert rods 7 is along the radial direction of the rotating drum 3. One end of the insert rod 7 is inserted into the rotating drum 3, and the connecting rod 8 is installed at the other end of the multiple insert rods 7. The length direction of the connecting rod 8 is parallel to the axial direction of the rotating drum 3.

[0045] In detail, the insert rod 7 and the connecting rod 8 can rotate synchronously with the rotating drum 3. The distance between the connecting rod 8 and the bottom surface of the equalizing trough 1 is the allowable material passage distance. As the rotating drum 3 rotates, the connecting rod 8 can push the material that cannot pass through upwards in the opposite direction, thereby preventing large-volume material from blocking the gap between the equalizing structure 2 and the equalizing trough 1. At the same time, due to the inclination of the equalizing trough 1 and the squeezing between the materials, when the feeding frame 4 rotates, the larger volume material can fall onto multiple insert rods 7, thereby using multiple insert rods 7 and the connecting rod 8 to transport and lift the material into the corresponding distributing trough 5. Meanwhile, the gap between two adjacent insert rods 7 allows smaller volume material to pass through, thus using this gap to also perform the screening work of the material.

[0046] It should be noted that without the connecting rod 8, larger or longer materials can slide down the equalization trough 1 through the gap between two adjacent insert rods 7, thus failing to intercept larger materials. The connecting rod 8 can prevent this phenomenon and improve the grading optimization effect.

[0047] like Figure 5 As shown, the insertion rod 7 slides on the rotating cylinder 3 along the length direction of the insertion rod 7;

[0048] The rotating drum 3 is provided with a guide structure, which is used to make the connecting rod 8 move along the length direction of the uniform material trough 1 after it moves to a specified distance close to the uniform material trough 1.

[0049] In detail, since the insert rod 7 can slide on the rotating drum 3, the distance between the connecting rod 8 and the rotating drum 3 is adjustable. The guide structure is used to limit the distance between the connecting rod 8 and the rotating drum 3. When the connecting rod 8 follows the rotating drum 3 to a specified distance from the bottom surface of the equalization trough 1, the distance between the connecting rod 8 and the bottom surface of the equalization trough 1 remains unchanged. At this time, the insert rod 7 will slide towards the inside of the rotating drum 3. Since the distance between the connecting rod 8 and the bottom surface of the equalization trough 1 remains unchanged, a long channel of a specified height will be formed between the flow equalization structure 2 and the bottom surface of the equalization trough 1. This can form a stable flow equalization and optimization of the material, avoiding the situation where the length of the channel formed by the maximum distance between the connecting rod 8 and the equalization trough 1 is too short when the insert rod 7 is fixed on the rotating drum 3. This would cause the next connecting rod 8 to be unable to fill the position in time when one connecting rod 8 passes through the position, resulting in an increase in the height of the channel. Larger volume materials would then pass through the high channel, making it impossible to effectively intercept larger volume materials.

[0050] It should be noted that because the channel is relatively long, it provides sufficient time for the links 8 to exchange. Before one link 8 moves out of the channel position, the next link 8 will move to the channel position in time, thus ensuring that the height of the channel is fixed.

[0051] like Figures 5 to 6 As shown, a spindle 9 is coaxially inserted in the middle of the rotating drum 3. Multiple connecting plates 10 are provided on the outer wall of the spindle 9. The connecting plates 10 are fixed on the inner wall of the rotating drum 3. The insertion rod 7 is slidably installed on the surface of the connecting plate 10.

[0052] The guide structure includes two fixed disks 12 installed at both ends of the rotating drum 3, and the rotating drum 3 rotates on the fixed disks 12. The spindle 9 passes through the fixed disks 12 and rotates relative to them. A guide groove is provided on the fixed disks 12. The guide groove is composed of a first arc groove 13 and a second arc groove 14. Among the multiple insert rods 7 on the feeding frame 4, the two insert rods 7 located at both ends of the connecting rod 8 are provided with sliding columns 11. The sliding columns 11 are slidably installed in the guide groove.

[0053] When the sliding column 11 slides in the first arc groove 13, the insertion rod 7 rotates synchronously with the rotating cylinder 3, and the insertion rod 7 is relatively stationary with respect to the rotating cylinder 3. When the sliding column 11 slides in the second arc groove 14, the insertion rod 7 slides on the rotating cylinder 3.

[0054] In detail, the spindle 9 can be connected to the rotating drum 3 through multiple connecting plates 10, thereby driving the rotating drum 3 to rotate. The spindle 9 and the connecting plates 10 support the rotating drum 3. The position of the fixed plate 12 is fixed, and the rotating drum 3 can rotate on the fixed plate 12. The center of the first arc groove 13 coincides with the axis of the spindle 9, and the center of the second arc groove 14 is located outside the guide groove. The overall shape of the guide groove is annular.

[0055] In use, the spindle 9 drives the rotating drum 3 to rotate through multiple connecting plates 10. The rotating drum 3 drives multiple material feeding frames 4 on it to rotate synchronously. That is, the insertion rod 7 and the connecting rod 8 move synchronously with the rotating drum 3. The insertion rod 7 drives the sliding column 11 to slide in the guide groove. When the sliding column 11 slides in the first arc groove 13, the position of the insertion rod 7 on the rotating drum 3 is fixed. At this time, the insertion rod 7 and the connecting rod 8 are away from the material equalization trough 1. When the sliding column 11 slides in the second arc groove 14, the insertion rod 7 and the connecting rod 8 approach the material equalization trough 1, and the sliding column 11 pulls the insertion rod 7 to slide on the rotating drum 3. The distance between the connecting rod 8 and the rotating drum 3 changes, while the distance between the connecting rod 8 and the bottom surface of the material equalization trough 1 remains unchanged. This forms a long channel of a specified height between the flow equalization structure 2 and the material equalization trough 1, which facilitates the time for the alternating work of multiple connecting rods 8 on the rotating drum 3.

[0056] like Figure 2 , Figure 3 and Figure 7 As shown, multiple sliding openings are provided on the front and rear side walls of the material leveling tank 1. The length direction of the sliding opening is perpendicular to the material leveling tank 1 on the vertical plane. A first slider 15 is slidably arranged in the sliding opening. The mandrel 9 passes through the first slider 15 and is rotatably connected to it. A worm gear 16 is provided on the mandrel 9.

[0057] The front and rear side walls of the material leveling tank 1 are each provided with a worm gear 17 and a first motor 18. The first motor 18 provides power to the worm gear 17. The worm gear 17 is meshed with multiple worm wheels 16 on the side wall of the material leveling tank 1.

[0058] The fixed plate 12 is fixed on the first slider 15.

[0059] In detail, the first motor 18 can drive multiple worm gears 16 to rotate via the worm 17, and the worm gears 16 drive the spindle 9 to rotate, thereby providing power to the flow equalization structure 2.

[0060] The first slider 15 provides an installation position for the fixed plate 12. When the first slider 15 slides in the sliding port, the distance between the flow equalization structure 2 and the material equalization trough 1 changes, thereby adjusting the specification requirements of the flow equalization structure 2 for material classification optimization.

[0061] like Figure 2 , Figure 3 and Figure 7 As shown, the end of the mandrel 9 is connected to the worm gear 17 via a connecting frame 19. One end of the worm gear 17 is rotatably mounted on the side wall of the material leveling tank 1 via a support shaft 20. The first motor 18 is mounted on the other end of the worm gear 17. The first motor 18 is connected to the material leveling tank 1 via an adjusting cylinder 21.

[0062] In detail, the connecting frame 19 is rotatably connected to the spindle 9 and the worm gear 17 respectively. The connecting frame 19 can realize the connection between the spindle 9 and the worm gear 17, so that the spindle 9 and the worm gear 17 always remain in a meshing state when the first slider 15 moves. When the adjusting cylinder 21 extends and retracts, it can drive the first motor 18 to move up and down, thereby using the first motor 18 to push the worm gear 17 to tilt and rotate. The worm gear 17 can drive multiple first sliders 15 to move through multiple connecting frames 19, thereby synchronously adjusting the position of multiple sets of flow equalization structures 2, and ensuring that the distance between the multiple sets of flow equalization structures 2 and the bottom surface of the equalization tank 1 always remains uniformly varied. The support shaft 20 can support the worm gear 17.

[0063] In actual use, multiple optical axis areas are opened on the worm 17. The worm 17 slides through the connecting frame 19 through the optical axis area, thereby realizing the connection between the worm 17 and the connecting frame 19. At this time, the connecting frame 19 will not interfere with the rotation of the worm 17. When the worm 17 tilts, the connecting frame 19 will slide on the worm 17 because the movement trajectory of the worm 17 is inconsistent with the movement trajectory of the first slider 15.

[0064] like Figure 3 As shown, a second slider 22 is slidably disposed on the side wall of the material distribution trough 5. The second slider 22 is connected to the material equalization trough 1 through a side plate 23, and the second slider 22 rotates on the side plate 23. The material distribution trough 5 is connected to the fixed plate 12 through a push-pull plate 24.

[0065] In detail, the flow equalization structure 2 and the material distribution trough 5 are connected by a push-pull plate 24. One end of the push-pull plate 24 is rotatably connected to the fixed plate 12, and the other end of the push-pull plate 24 is fixedly connected to the material distribution trough 5. The side plate 23 and the second slider 22 can provide support for the material distribution trough 5. When the flow equalization structure 2 and the first slider 15 move, the flow equalization structure 2 will pull the material distribution trough 5 to move synchronously through the push-pull plate 24, so that the position of the material distribution trough 5 and the flow equalization structure 2 always corresponds. At this time, the material distribution trough 5 will slide on the second slider 22, and the material distribution trough 5 will synchronously drive the second slider 22 to rotate on the side plate 23.

[0066] like Figure 8 As shown, the vibration mechanism also includes a second motor 25. The output end of the second motor 25 is provided with a disk 26. A eccentrically mounted paddle 27 is provided on the disk 26. A long groove plate 28 is sleeved on the outer side of the paddle 27. The long groove plate 28 is fixedly connected to multiple material equalization long plates 6 on the vibration mechanism.

[0067] The length direction of the long groove plate 28 is perpendicular to the sliding direction of the uniform material long plate 6.

[0068] In detail, the second motor 25 on the vibration mechanism is fixed on the material equalization trough 1 or the material distribution trough 5. When the second motor 25 is running, it can drive the shifting column 27 to rotate eccentrically through the disc 26. The shifting column 27 will drive multiple material equalization plates 6 to slide on the material equalization trough 1 or the material distribution trough 5 through the long groove plate 28, thereby providing power to the multiple material equalization plates 6. At the same time, the shifting column 27 will slide in the long groove plate 28.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
