Description

Technical Field

[0001] This utility model relates to the field of antimony ore screening technology, specifically a multi-layer superimposed dry screening device for antimony ore. Background Technology

[0002] Antimony ore refers to minerals rich in antimony and with industrial value. It is silvery-white, easily fusible and brittle, with poor electrical and thermal conductivity. It does not oxidize at room temperature, but burns to form antimony oxides when heated. There are only 10 antimony minerals with an antimony content of more than 20%, including stibnite, stigmonite, and antimony oxide. Among them, stibnite is the most important mineral raw material for antimony beneficiation. Antimony trioxide is the most commonly used flame retardant synergist. When used in combination with halogen flame retardants, it can significantly improve the fire resistance of plastics, cables, and textiles. It is widely used in automotive interiors, electrical components, building materials, etc. Antimony ore dry screening equipment is suitable for antimony ore with low moisture content. In a dry environment, the vibration of the screen surface causes the mineral particles to pass through the screen holes according to their particle size to achieve classification. This method does not require water and has a simple process, but it produces a lot of dust and requires dust removal equipment.

[0003] In some existing multi-layer superimposed dry screening equipment for antimony ore, the superimposed multi-layer screens are driven to vibrate at high frequency by a vibrating motor exciter during the screening of antimony ore. The antimony ore falls from the top feed port to the top screen. The screen aperture is layered from large to small. The vibration causes the material smaller than the upper screen aperture to fall into the lower layer, while the larger particles remain in the upper layer. After screening layer by layer, the material of different particle sizes is discharged from the corresponding discharge port. When it is necessary to clean and replace the screen, it is necessary to turn several bolts to open the top cover, and then loosen the bolts at the edge of the screen to remove the screen.

[0004] Existing multi-layer stacked dry screening equipment for antimony ore has the following problems: when screening antimony ore, the screen is fixed by bolts, which makes the disassembly and assembly operation complicated and time-consuming, and the equipment downtime is long, reducing the working efficiency of antimony ore screening. To address this, we propose a multi-layer stacked dry screening equipment for antimony ore. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multi-layer superimposed antimony ore dry screening equipment. When screening antimony ore, the screen is fixed by a simple plug-in method, which makes disassembly and assembly simple, reduces the waste of time, shortens the equipment downtime, and improves the working efficiency of antimony ore screening. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer superimposed antimony ore dry screening equipment, including a base plate, a screening box at the upper end of the base plate, and evenly distributed sockets on the left and right inner walls of the screening box, with screens inserted between two horizontally adjacent sockets, and also includes a fixing mechanism.

[0007] The fixing mechanism includes an adjusting platform, insertion holes, insertion rods, and sliding plates. Adjusting platforms are evenly distributed on the left and right sides of the front end of the screening box. Sliding plates are slidably connected inside the adjusting platforms, and insertion rods are fixedly connected to the opposite inner surfaces of the sliding plates. Insertion holes are opened on the left and right sides of the front end of the screen, and these holes are fitted with adjacent horizontal insertion rods. When screening antimony ore, the screen is fixed using a simple insertion method, simplifying assembly and disassembly, reducing time waste, shortening equipment downtime, and improving the efficiency of antimony ore screening.

[0008] Furthermore, a control switch is provided on the outside of the base plate, and the input terminal of the control switch is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the fixing mechanism also includes telescopic rods and springs. The inner wall of the adjusting platform and the opposite outer side of the horizontally adjacent sliding plate are respectively fixedly connected with evenly distributed telescopic rods, and springs are respectively sleeved on the outside of the telescopic rods to provide rebound.

[0010] Furthermore, the fixing mechanism also includes a connecting rod, a Z-shaped tie rod, and a stop rod. The middle part of the opposite outer side of the sliding plate is fixedly connected to the connecting rod. The end of the connecting rod away from the center of the base plate is rotatably connected to the Z-shaped tie rod. The upper end of the adjusting platform is fixedly connected to the stop rod. The upper end of the Z-shaped tie rod is respectively installed in conjunction with the longitudinally adjacent stop rod for easy installation.

[0011] Furthermore, symmetrical support columns are provided on the front and rear sides of the upper end of the base plate. Mounting blocks are fixedly connected to the front and rear sides of the left and right ends of the screening box. Symmetrical telescopic columns are fixedly connected between the upper end of the support column and the lower end of the vertically adjacent mounting block. A spring is sleeved on the outside of each telescopic column. The spring is fixedly connected between the upper end of the support column and the lower end of the vertically adjacent mounting block. The height of the two rear support columns is higher than the height of the two front support columns, and the height of the two rear mounting blocks is higher than the height of the two front mounting blocks, providing support.

[0012] Furthermore, the upper end of the screening box is provided with symmetrical vertical blocks, and rotating columns are rotatably connected to the opposite outer sides of the vertical blocks.

[0013] Furthermore, counterweights are fixedly connected to the end of the rotating column away from the center of the screening box.

[0014] Furthermore, a feeding chute is provided at the feed inlet at the upper end of the screening box to facilitate feeding.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This multi-layer superimposed antimony ore dry screening equipment has the following advantages:

[0016] By pulling the Z-shaped lever so that its right end passes the stop bar and rotates clockwise, the stop bar provides a limiting position. Simultaneously, pulling the Z-shaped lever causes the connecting rod to disengage from the insertion hole via the connecting rod and sliding plate. As the sliding plate moves, it presses against the telescopic rod and spring two, allowing the screen to be removed. After removal, insert the screen back into the socket. Rotating the Z-shaped lever counterclockwise releases the limiting position, causing spring two and the telescopic rod to spring back, re-inserting the insertion rod into the insertion hole and fixing the screen. In antimony ore screening, the screen is fixed using a simple insertion method, simplifying assembly and disassembly, reducing time waste, shortening equipment downtime, and improving the efficiency of antimony ore screening.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This embodiment provides a technical solution: a multi-layer superimposed antimony ore dry screening equipment, including a base plate 1, a screening box 6 at the upper end of the base plate 1, and evenly distributed sockets 7 on the left and right inner walls of the screening box 6. A screen 8 is inserted between two horizontally adjacent sockets 7. It also includes a fixing mechanism 9. A control switch 15 is provided on the outside of the base plate 1, and the input end of the control switch 15 is electrically connected to an external power source. Symmetrical support columns 2 are provided on the front and rear sides of the upper end of the base plate 1. Mounting blocks 5 are fixedly connected to the front and rear sides of the left and right ends of the screening box 6. The upper end of the support columns 2 is connected to the vertical... Symmetrical telescopic columns 3 are fixedly connected to the lower ends of adjacent mounting blocks 5. Springs 4 are fitted onto the outside of each telescopic column 3, and are fixedly connected between the upper end of the support column 2 and the lower end of the vertically adjacent mounting block 5. The height of the two rear support columns 2 is higher than that of the two front support columns 2, and the height of the two rear mounting blocks 5 is higher than that of the two front mounting blocks 5. Symmetrical upright blocks 10 are provided at the upper end of the screening box 6. Rotating columns 11 are rotatably connected to the opposite outer surfaces of the upright blocks 10. The ends of the rotating columns 11 furthest from the center of the screening box 6 are respectively... A counterweight 12 is fixedly connected. A dual-axis motor 13 is installed in the middle of the upper end of the screening box 6. The output shafts of the dual-axis motor 13 are fixedly connected to the opposite ends of the laterally adjacent rotating columns 11. The input end of the dual-axis motor 13 is electrically connected to the output end of the control switch 15. A feed chute 14 is provided at the feed inlet at the upper end of the screening box 6. When screening antimony ore, the processing equipment is placed in an appropriate position through the bottom plate 1, and then the antimony ore material enters the interior of the screening box 6 through the feed chute 14. Then, by controlling the control switch 15, the dual-axis motor 13 operates, and the output shaft of the dual-axis motor 13 drives the left and right sides. The rotating column 11 rotates synchronously in opposite directions, driving the counterweight 12 to rotate at high speed, generating periodic centrifugal force. This causes the screening box 6 to vibrate at high frequency under the elastic support of the telescopic column 3 and the spring 4. Since the rear support column 2 and the mounting block 5 are higher than the front, the screening box 6 is tilted. The vibration direction and the tilt angle work together to make the material move in a parabolic motion from back to front on the screen 8. The diameter of the screen holes at the upper end of the screen 8 decreases from top to bottom, thus separating antimony ore of different sizes into layers. After screening, different antimony ores will be guided through the external guide chute corresponding to the front end of each screen 8.

[0023] Fixed mechanism 9 includes an adjusting platform 91, insertion holes 92, insertion rods 93, and sliding plates 94. Adjusting platforms 91 are evenly distributed on the left and right sides of the front end of the screening box 6. Sliding plates 94 are slidably connected inside the adjusting platforms 91. Insertion rods 93 are fixedly connected to the opposite inner surfaces of the sliding plates 94. Insertion holes 92 are opened on the left and right sides of the front end of the screen 8. The insertion holes 92 are respectively fitted with the horizontally adjacent insertion rods 93. Fixed mechanism 9 also includes a telescopic rod 95 and a spring 96 for adjustment. The inner wall of the platform 91 and the opposite outer side of the horizontally adjacent sliding plate 94 are respectively fixedly connected by evenly distributed telescopic rods 95. Springs 96 are respectively sleeved on the outside of the telescopic rods 95. The fixing mechanism 9 also includes connecting rods 97, Z-shaped pull rods 98, and stop rods 99. Connecting rods 97 are fixedly connected to the middle part of the opposite outer side of the sliding plate 94. Z-shaped pull rods 98 are rotatably connected to the end of each connecting rod 97 away from the center of the base plate 1. Stop rods 99 and Z-shaped pull rods 98 are fixedly connected to the upper end of the adjusting platform 91. The upper end of screen 8 is installed in conjunction with the longitudinally adjacent stop bar 99. When screen 8 needs to be removed, replaced, or cleaned, first pull the Z-shaped pull rod 98 to the left so that the right end of the Z-shaped pull rod 98 is on the left side of the stop bar 99. Then rotate the Z-shaped pull rod 98 clockwise so that the stop bar 99 blocks the Z-shaped pull rod 98. When the Z-shaped pull rod 98 is pulled, the sliding plate 94 is driven to slide to the left inside the adjusting table 91 through the connecting rod 97. While the sliding plate 94 is moving, it also moves the telescopic rod 95 and the spring 96. The squeezing action will cause the insertion rod 93 to disengage from the insertion hole 92, thereby removing the screen 8 from the obstruction. Then, the screen 8 will be pulled out from between the sockets 7. Next, the screen 8 will be cleaned or replaced. After cleaning or replacement, the screen 8 will be inserted between the two sockets 7. Then, the Z-shaped pull rod 98 will be rotated counterclockwise to disengage it from the obstruction of the stop rod 99. Then, the sliding plate 94 will be pushed by the extension rod 95 and the spring 96 to insert the insertion rod 93 into the insertion hole 92, thereby fixing the screen 8.

[0024] The working principle of the multi-layer superimposed antimony ore dry screening equipment provided by this utility model is as follows: When screening antimony ore, the equipment is placed in an appropriate position through the bottom plate 1. Then, the antimony ore material enters the screening box 6 through the feeding chute 14. Then, by controlling the switch 15, the dual-shaft motor 13 operates. The output shaft of the dual-shaft motor 13 drives the rotating columns 11 on the left and right sides to rotate synchronously in opposite directions, driving the counterweight block 12 to rotate at high speed, generating periodic centrifugal force. This causes the screening box 6 to generate high-frequency vibration under the elastic support of the telescopic column 3 and spring 4. Since the height of the rear support column 2 and the mounting block 5 is higher than that of the front side, the screening box 6 is tilted. The vibration direction and the tilt angle work together to make the material perform a parabolic motion from back to front on the screen 8. The diameter of the screen holes at the upper end of the screen 8 decreases from top to bottom, and antimony ore of different sizes is screened in layers. After screening, different antimony ores will be guided through the external guide chute corresponding to the front end of each screen 8. When it is necessary to adjust the screen... 8. When disassembling, replacing, or cleaning, first pull the Z-shaped pull rod 98 to the left, so that the right end of the Z-shaped pull rod 98 is to the left of the stop lever 99. Then, rotate the Z-shaped pull rod 98 clockwise so that the stop lever 99 blocks the Z-shaped pull rod 98. When pulling the Z-shaped pull rod 98, the sliding plate 94 is driven to slide to the left inside the adjusting platform 91 through the connecting rod 97. As the sliding plate 94 moves, it compresses the telescopic rod 95 and the second spring 96, thereby causing the plug-in rod 93 to disengage from the stop lever 99. Insert the screen 8 into the insertion hole 92, and the screen 8 will be removed from the obstruction. Then, pull the screen 8 out from between the sockets 7. Next, clean or replace the screen 8. After cleaning or replacement, insert the screen 8 between two horizontally adjacent sockets 7. Then, rotate the Z-shaped pull rod 98 counterclockwise to remove the Z-shaped pull rod 98 from the obstruction of the stop bar 99. Then, under the rebound of the telescopic rod 95 and the second spring 96, the sliding plate 94 drives the insertion rod 93 to insert into the insertion hole 92, thereby fixing the screen 8.

[0025] It is worth noting that the dual-axis motor 13 disclosed in the above embodiments can be YZR-180L-8 / 11KW, and the control switch 15 is provided with a switch button corresponding to the dual-axis motor 13 and used to control its switching operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
