Description

Technical Field

[0001] This invention relates to the field of ore crushing technology, specifically to a circulating crushing device for antimony ore in antimony ingot production. Background Technology

[0002] The main purpose of antimony ore crushing is to break large pieces of antimony ore into smaller particles to facilitate subsequent beneficiation processes. Crushing increases the surface area of ​​the ore, improving the contact efficiency between the ore and beneficiation reagents, thereby enhancing the beneficiation effect. Commonly used crushing devices include jaw crushers, cone crushers, and ball mills.

[0003] After ordinary crushers grind antimony ore, the resulting ore particles have a wide particle size distribution. To obtain ore of the target particle size, screening is necessary. Larger particles need to be manually or mechanically fed back into the crusher for secondary crushing, which is cumbersome and inefficient. Furthermore, the feed inlet of the crusher is generally open, allowing large amounts of dust to fly out during the crushing process, affecting worker health. Therefore, further improvements are needed. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a circulating crushing device for antimony ore in antimony ingot production, which has the following beneficial effects:

[0018] 1. In this antimony ingot production, the circulating crushing device for antimony ore uses a connecting plate and a push rod to drive a push plate to move back and forth. When the push plate slides to fit against the left side wall of the storage hopper, the storage hopper is connected to the feeding port through a dust hood. The antimony ore in the storage hopper falls into the dust hood under gravity. At this time, the antimony ore inside the storage hopper can block dust, preventing it from scattering out of the storage hopper. Then, the push plate moves to the right, pushing the antimony ore in the dust hood to the feeding port. The antimony ore passes through the feeding port and falls between the driven crushing rollers, completing the feeding process. When the push plate moves to the right side of the storage hopper, it can separate the storage hopper and the feeding port, preventing dust from escaping from the crushing chamber; thus achieving the purpose of suppressing dust from scattering out of the feeding port.

[0019] 2. The circulating crushing device for antimony ore in this antimony ingot production uses driven and driven crushing rollers to rotate, and crushing teeth one and two to crush the antimony ore. The crushed antimony ore falls onto a screen plate. Smaller particles pass through the screen holes and fall onto the top of the inclined plate; larger particles are retained at the top of the screen plate. During the reciprocating movement of the horizontal plate, the L-shaped plate connects and drives the screen plate to move back and forth, causing the antimony ore at the top of the screen plate to move towards the driven or driven crushing roller. The crushing teeth one or two then push the larger particles upward along the arc surface, allowing them to pass between the driven and driven crushing rollers again for further crushing. Furthermore, during the pushing of the antimony ore by the crushing teeth one or two, the antimony ore impacts the V-shaped end of the arc-shaped partition, further crushing it. This achieves the purpose of circulating crushing of antimony ore, improving processing efficiency.

[0020] 3. In the antimony ingot production process, the circulating crushing device for antimony ore, during the reciprocating movement of the screen plate, scoops up the antimony ore stuck in the screen holes by the bottom edge of the protrusion, preventing the screen holes from being blocked and ensuring the screening effect; during the reciprocating movement of the horizontal plate, the connecting plate three drives the sliding arm and the rack plate to move back and forth, driving the threaded rod and the gear three to rotate back and forth, thereby driving the threaded tube to move up and down; when the spring one is compressed and contracted, when the elasticity of the spring one breaks through the limiting effect between the embedded column and the hemispherical groove, the fixed plate one moves upward rapidly under the elastic action of the spring one, knocking up the antimony ore on its upper surface, causing the antimony ore to hit the bottom of the screen plate, promoting the antimony ore stuck inside the column to fall off; thus achieving the purpose of preventing the screen holes from being blocked and ensuring the stability of the screening effect.

[0037] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "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 present invention and simplifying the description, and are not intended to 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 this application.

[0038] 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.

[0039] Please see Figures 1-2A circulating crushing device for antimony ore in antimony ingot production includes a crushing box 100. A feeding port 101 is provided through the top of the crushing box 100, and a discharge port 102 is provided in the lower right half of the crushing box 100. Enclosure assemblies 500 are welded to the left and right side walls of the upper half of the crushing box 100. The two enclosure assemblies 500, together with the front and rear side walls of the crushing box 100, form a crushing chamber. A driven crushing roller 200 and a driven crushing roller 300 are rotatably connected between the front and rear side walls of the crushing chamber. A rotation drive component 400 is provided between the ends of the driven crushing roller 200 and the driven crushing roller 300. A screening plate assembly 600 is attached to the bottom of the two enclosure assemblies 500 and slidably connected to the crushing box 100. A feeding assembly 700 is provided at the top of the crushing box 100, and a guide assembly 800 is provided inside the lower half of the crushing box 100.

[0040] Please see Figures 3-4 The driven crushing roller 200 has a surface array of crushing teeth 201, and the driven crushing roller 300 has a surface array of crushing teeth 301. The crushing teeth 201 and 301 are staggered in the front-to-back direction. Thus, when the driven crushing roller 200 and the driven crushing roller 300 rotate, the crushing teeth 201 and 301 crush the ore by compression. The rotation drive unit 400 includes a reducer 401 fixedly mounted on the back of the crushing box 100. A motor 402 is fixedly mounted on the input end of the reducer 401, and the output end of the reducer 401 is fixedly mounted on the rear end of the driven crushing roller 300. A gear 403 is fixedly mounted on the front end of the driven crushing roller 200, and a gear 404 is fixedly mounted on the front end of the driven crushing roller 300. The gears 403 and 404 mesh with each other. Thus, the reducer 401 and motor 402 drive the active crushing roller 300 to rotate, which, in conjunction with the meshing of gear 1 403 and gear 2 404, drives the driven crushing roller 200 to rotate. The driven crushing roller 200 and the active crushing roller 300 rotate in opposite directions.

[0041] Please see Figures 3-4The enclosure assembly 500 includes two protrusions 501 welded to the left and right side walls of the crushing box 100. Each protrusion 501 has an arc-shaped surface 502 on its opposite side. The bottom of each protrusion 501 is horizontal and tangent to the arc-shaped surface 502. The screening plate assembly 600 is attached to the bottom of the protrusions 501. The centers of the arcs of the two arc-shaped surfaces 502 coincide with the axes of the driven crushing roller 200 and the driven crushing roller 300, respectively. The free end of crushing tooth 201 is attached to the arc-shaped surface 502 on the left side, and the free end of crushing tooth 301 is attached to the arc-shaped surface 502 on the right side. Thus, after the antimony ore is fed into the feed port 101, it falls between the driven crushing roller 200 and the driven crushing roller 300. The driven crushing roller 300 rotates counterclockwise, and the driven crushing roller 200 rotates clockwise, crushing the antimony ore. After being crushed, the antimony ore is screened by the screening plate assembly 600. Larger particles are retained at the top of the assembly. Then, driven by the crushing teeth 301 and 201, these larger particles are transferred along the arc-shaped surface 502 to above the driven crushing roller 200 or the driving crushing roller 300. Subsequently, as the driven and driving crushing rollers rotate, they are transferred again between them, thus further crushing the antimony ore.

[0042] Arc-shaped spacers 503 are fixedly arranged on both arc-shaped surfaces 502. The bottom of the arc-shaped spacers 503 is V-shaped. The arc-shaped spacer 503 on the left is used to separate the front and rear distributed crushing teeth 201, and the arc-shaped spacer 503 on the right is used to separate the front and rear distributed crushing teeth 301. When the crushing teeth 301 and the crushing teeth 201 transfer antimony ore with larger particle size, some antimony ore will get stuck between two adjacent crushing teeth 201 or two adjacent crushing teeth 301. As the larger antimony ore moves with the crushing teeth 201 or the crushing teeth 301, it will hit the bottom of the arc-shaped spacer 503, thereby crushing the antimony ore.

[0043] Please see Figures 5-7 The screening plate assembly 600 includes a screen plate 601 attached to the bottom of two enclosure assemblies 500. The surface of the screen plate 601 has an array of through-holes 602. Sliding strips 603 are fixedly installed on the front, rear, and rear sides of the screen plate 601. Sliding grooves 103 are formed on the front and rear inner walls of the crushing box 100, and the sliding strips 603 are slidably connected within the sliding grooves 103. Thus, as the screen plate 601 moves left and right along the sliding grooves 103, the crushed antimony ore falls onto the screen plate 601, ensuring effective screening. Furthermore, larger particles of antimony ore will move left and right with the screen plate 601, allowing them to be transferred below the driven crushing roller 200 or the active crushing roller 300, facilitating the pushing of the antimony ore towards the arc-shaped surface 502 by the first crushing tooth 201 or the second crushing tooth 301.

[0044] Two L-shaped plates 604 are fixedly installed on the left side of the sieve plate 601. The horizontal portions of the L-shaped plates 604 are slidably connected to the crushing box 100. A horizontal plate 605 is fixedly installed on the top of the two L-shaped plates 604. A connecting plate 606 is fixedly installed at both ends of the horizontal plate 605, and the connecting plate 606 is perpendicular to the horizontal plate 605. A vertical frame plate 607 is fixedly installed on the right end of the connecting plate 606. Turntables 608 are coaxially fixed at both ends of the driven crushing roller 200. One turntable 608 is fixed at the rear end of the driven crushing roller 200, and the other turntable 608 is fixedly installed in front of the gear 403. A sliding column 609 is fixedly installed at the eccentric part of the surface of the turntable 608, and the sliding column 609 is slidably connected inside the vertical frame plate 607. Thus, when the driven crushing roller 200 rotates, it drives the turntable 608 to rotate, and the sliding column 609 performs a circular motion. During this process, the sliding column 609 slides within the vertical frame plate 607, pushing the vertical frame plate 607 to move left and right. Under the connecting action of the connecting plate 606, it drives the horizontal plate 605 to move back and forth. Then, through the connecting action of the L-shaped plate 604, the screen plate 601 moves back and forth. Since some antimony ore may get stuck inside the screen holes 602, during the left and right movement of the screen plate 601, the bottom edge of the boss 501 scrapes away the antimony ore stuck in the screen holes 602, thus preventing blockage.

[0045] Please see Figures 6-7 The feeding assembly 700 includes a dust cover 701 fixedly installed on the top of the crushing box 100. The right half of the dust cover 701 communicates with the feeding port 101. A storage hopper 702 is welded to the top left end of the dust cover 701 for temporary storage of antimony ore. A slot 703 and two insertion holes 704 are opened through the left side of the storage hopper 702. The two insertion holes 704 are located below the slot 703. A support plate 705 is slidably connected inside the slot 703. The support plate 705 is attached to the top wall of the dust cover 701. A push plate 706 is fixedly installed at the bottom right end of the support plate 705 and is attached to the top of the crushing box 100. Two push rods 707 are fixedly installed on the left side of the push plate 706. The push rods 707 are slidably connected to the insertion holes 704. A connecting plate 708 is fixedly installed at the left end of the push rods 707. The bottom end of the connecting plate 708 is fixedly installed on the top of the horizontal plate 605.

[0046] As the horizontal plate 605 moves back and forth, the connecting plate 708 and the push rod 707 cause the push plate 706 and the support plate 705 to move synchronously back and forth. When the push plate 706 moves to the right side of the storage hopper 702, it can separate the storage hopper 702 and the feeding port 101, preventing dust from being discharged from the crushing box 100. When the push plate 706 slides to fit against the left side wall of the storage hopper 702, the storage hopper 702 is connected to the feeding port 101 through the dust cover 701. The antimony ore in the storage hopper 702 falls into the dust cover 701 under the action of gravity. At this time, the antimony ore inside the storage hopper 702 can block the dust and prevent the dust from flying out of the storage hopper 702. Afterwards, the push plate 706 moves to the right, which can push the antimony ore in the dust cover 701 to the feeding port 101 to complete the feeding.

[0047] Please see Figures 8-11 The guiding assembly 800 includes four sleeves 801 fixedly installed on the bottom wall of the crushing box 100. The four sleeves 801 are arranged in a matrix. Columns 802 are slidably connected to the top of each sleeve 801. Inclined plates 803 are fixedly installed at the top of the four columns 802. The inclined plates 803 are inclined, with the left side higher than the right. Antimony ore screened by the screen plate 601 falls onto the inclined plates 803 and, guided by the inclined plates 803, moves towards the discharge port 102. Support members are provided at the bottom of the inclined plates 803.

[0048] Please see Figures 9-11 The support includes two vertical rods 804 fixedly installed on the lower surface of the inclined plate 803. The two vertical rods 804 are distributed front to back. A fixing plate 805 is fixedly installed at the bottom of the two vertical rods 804. Two springs 806 are fixedly installed at the bottom of the fixing plate 805. A fixing plate 807 is fixedly installed at the bottom of the two springs 806. Two inverted L-shaped frames 808 are fixedly installed on the bottom wall of the crushing box 100. The inverted L-shaped frames 808 are inverted L-shaped. The vertical rods 804 slide through and are slidably connected to the horizontal part of the inverted L-shaped frames 808. The front end and rear end of the fixing plate 805 are respectively attached to the opposite side of the two inverted L-shaped frames 808. Elastic limiting members are provided between both ends of the fixing plate 805 and the inverted L-shaped frames 808. A lifting drive 900 is provided at the bottom of the fixing plate 807, which pushes the fixing plate 807 to move up and down reciprocally.

[0049] Please see Figures 9-11Two sets of elastic limiting members are provided at both ends of the fixing plate 805. Each set of elastic limiting members includes a post 810 and a spring 811. Two mounting holes 809 are provided at both ends of the fixing plate 805. The post 810 is slidably connected in the mounting hole 809. The two ends of the spring 811 are respectively fixed between the end of the post 810 and the inner wall of the mounting hole 809. The other end of the mounting hole 809 is hemispherical. Two hemispherical grooves 812 are provided in the middle of the opposite side of the two inverted L-shaped brackets 808. The hemispherical end of the mounting hole 809 is attached to the hemispherical groove 812. Thus, under the elastic action of the spring 811, the post 810 is attached to the hemispherical groove 812, so that the fixing plate 807 can be stably held at the hemispherical groove 812.

[0050] Please see Figures 10-11 The lifting drive component 900 includes a connecting plate 3 901 fixedly installed at the bottom of the horizontal plate 605. A sliding arm 902 is fixedly installed at the bottom end of the connecting plate 3 901. The sliding arm 902 is slidably connected to the crushing box 100. A rack plate 903 is fixedly installed on the front side of the sliding arm 902. A support base 904 and a bushing 905 are fixedly installed on the bottom wall of the crushing box 100. The sliding arm 902 is slidably connected to the support base 904, which supports and guides the sliding arm 902. Thus, when the horizontal plate 605 moves left and right reciprocatingly, the sliding arm 902 and the rack plate 903 move left and right synchronously under the connecting action of the connecting plate 3 901.

[0051] A threaded rod 906 is rotatably connected to the bushing 905, and a gear 907 is fixedly mounted on the threaded rod 906. The rack plate 903 meshes with the gear 907. Thus, when the rack plate 903 moves back and forth, it drives the gear 907 and the threaded rod 906 to rotate back and forth.

[0052] A threaded tube 908 is fixedly inserted through the center of the second fixing plate 807. The threaded tube 908 is threadedly connected to the threaded rod 906. A protruding rib 909 is fixedly installed on the outer wall of the threaded tube 908. A blocking block 911 is fixedly installed at the top of the protruding rib 909. The blocking block 911 is located directly above the second fixing plate 807. A clearance groove 910 is opened through the center of the first fixing plate 805. The threaded tube 908 and the protruding rib 909 are slidably connected in the clearance groove 910. Thus, when the threaded rod 906 reciprocates, it drives the threaded tube 908 and the second fixing plate 807 to move up and down reciprocally.

[0053] As the threaded tube 908 and the second fixing plate 807 move upward, the threaded tube 908 and the protrusion 909 slide relative to the first fixing plate 805, reducing the distance between the second fixing plate 807 and the first fixing plate 805, and the first spring 806 is compressed. When the elasticity of the first spring 806 breaks through the limiting effect between the embedded post 810 and the hemispherical groove 812, the embedded post 810 slides into the mounting hole 809. Under the elastic action of the first spring 806, the first fixing plate 805 moves upward rapidly, thereby driving the inclined plate 803 to move upward rapidly until the first fixing plate 805 is attached to the lower surface of the horizontal part of the inverted L-shaped frame 808. Thus, the upward movement of the inclined plate 803 knocks up the antimony ore on its upper surface, causing the antimony ore to hit the bottom of the screen plate 601, promoting the falling of the antimony ore stuck inside the column 802. The tilting plate 803 also knocks up the antimony ore, preventing it from accumulating on the top of the inclined plate 803 and hindering the downward movement of subsequent antimony ore. Ensure the stability of material discharge.

[0054] When in use, antimony ore is put into the storage hopper 702, and then the active crushing roller 300 is driven to rotate by the reducer 401 and the motor 402. In conjunction with the meshing of gear 1 403 and gear 2 404, the driven crushing roller 200 is driven to rotate, thereby driving the two turntables 608 to rotate. The mounting hole 809 makes a circular motion, pushing the vertical frame plate 607, the connecting plate 1 606 and the horizontal plate 605 to move back and forth.

[0055] The push plate 706 moves back and forth through the connection between the connecting plate 708 and the push rod 707. When the push plate 706 slides to fit against the left side wall of the storage hopper 702, the storage hopper 702 is connected to the feeding port 101 through the dust cover 701. The antimony ore in the storage hopper 702 falls into the dust cover 701 under the action of gravity. At this time, the antimony ore inside the storage hopper 702 can block the dust and prevent the dust from flying out of the storage hopper 702. Then, the push plate 706 moves to the right, which can push the antimony ore in the dust cover 701 to the feeding port 101. The antimony ore falls between the driven crushing roller 200 and the driven crushing roller 200 through the feeding port 101, completing the feeding. When the push plate 706 moves to the right side of the storage hopper 702, it can separate the storage hopper 702 and the feeding port 101 to prevent the dust inside the crushing box 100 from being discharged.

[0056] As the driven crushing roller 200 and the driving crushing roller 300 rotate, the crushing teeth 201 and 301 crush the antimony ore. The crushed antimony ore falls onto the screen plate 601. The smaller antimony ore particles pass through the screen holes 602 and fall onto the top of the inclined plate 803. The larger antimony ore particles are trapped at the top of the screen plate 601.

[0057] During the reciprocating movement of the horizontal plate 605, the L-shaped plate 604 connects and drives the screen plate 601 to reciprocate, thereby moving the antimony ore at the top of the screen plate 601 toward the driven crushing roller 200 or the active crushing roller 300. The larger antimony ore particles are pushed upward along the arc surface 502 by the crushing teeth 201 or 301, so that the larger antimony ore particles pass between the driven crushing roller 200 and the active crushing roller 300 for further crushing. Moreover, during the process of the crushing teeth 201 or 301 pushing the antimony ore, the antimony ore also impacts the V-shaped end of the arc-shaped partition 503, which can also break the antimony ore.

[0058] During the reciprocating movement of the sieve plate 601, the antimony ore stuck in the sieve hole 602 is scooped up by the bottom edge of the protrusion 501, preventing the sieve hole 602 from being blocked and ensuring the screening effect.

[0059] During the reciprocating movement of the horizontal plate 605, the connecting plate 901 drives the sliding arm 902 and the rack plate 903 to reciprocate, which in turn drives the threaded rod 906 and the gear 907 to rotate, thereby driving the threaded tube 908 to move up and down.

[0060] As the threaded tube 908 and the second fixing plate 807 move upward, the threaded tube 908 and the protrusion 909 slide relative to the first fixing plate 805, reducing the distance between the second fixing plate 807 and the first fixing plate 805, and the first spring 806 is compressed. When the elasticity of the first spring 806 breaks through the limiting effect between the embedded post 810 and the hemispherical groove 812, the embedded post 810 slides into the mounting hole 809. Under the elastic action of the first spring 806, the first fixing plate 805 moves upward rapidly, thereby driving the inclined plate 803 to move upward rapidly until the first fixing plate 805 is attached to the lower surface of the horizontal part of the inverted L-shaped frame 808. Thus, the upward movement of the inclined plate 803 knocks up the antimony ore on its upper surface, causing the antimony ore to hit the bottom of the screen plate 601, promoting the falling of the antimony ore stuck inside the column 802.

[0061] As the threaded pipe 908 and the second fixed plate 807 move downwards, the blocking block 911 adheres to the top of the first fixed plate 805 and pulls the first fixed plate 805 downwards, causing the inclined plate 803 to move downwards. Since the inclined plate 803 is inclined, the antimony ore gathers towards the upper right end of the inclined plate 803. When the bottom end of the inclined plate 803 moves to below the bottom wall of the discharge port 102, the antimony ore is discharged through the discharge port 102.
