Description

[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] like Figures 1 to 5 As shown, this utility model provides a device for pre-screening of concentrated magnetic tailings for phosphorus beneficiation, including a screening box 1. A first hollow sleeve block 2 is fixedly installed on the outer right side of the screening box 1, and the first hollow sleeve block 2 extends into the interior of the screening box 1. A first rack 4 is slidably installed inside the first hollow sleeve block 2, and the first rack 4 extends into the interior of the screening box 1. A convex groove is formed on the top inner side of the first hollow sleeve block 2. A convex strip 3 is fixedly installed on the outer top of the first rack 4, and the convex strip 3 matches the convex groove formed inside the first hollow sleeve block 2. A support plate 5 is fixedly installed below the first hollow sleeve block 2 on the outer right side of the screening box 1. A first bracket 6 is fixedly installed on the top of the support plate 5. A first motor 7 is fixedly installed. A first half-toothed gear 8 is fixedly installed at the end of the output shaft of the first motor 7 and meshes with the first rack 4. A second hollow sleeve block 12 is fixedly installed on the inner wall of the left side of the slag-separating box 1. A spring 13 is placed inside the second hollow sleeve block 12 and one end of the spring 13 is fixedly connected to the inner wall of the slag-separating box 1. A transmission rod 14 is movably installed inside the second hollow sleeve block 12 and the other end of the spring 13 is fixedly connected to the transmission rod 14. L-shaped support plates 9 are fixedly installed on the inner sides of the transmission rod 14 and the first rack 4. A screen 10 is fixedly installed on the inner side of the L-shaped support plate 9 and is located between the two L-shaped support plates 9. A vibration mechanism is fixedly installed on the back of the slag-separating box 1.
[0023] When workers need to pre-screen the concentrated magnetic tailings for phosphorus beneficiation, they simultaneously start the first motor 7 and the vibration mechanism. The output shaft of the first motor 7 will drive the first half toothed gear 8 to start rotating. When the first half toothed gear 8 rotates, the upper half toothed gear meshes with the first rack 4, which will drive the first rack 4 to push the L-shaped support plate 9. When the L-shaped support plate 9 transmits the power to the other L-shaped support plate 9, it will squeeze the spring 13 through the transmission rod 14. When the upper half toothed gear of the first half toothed gear 8 does not mesh with the first rack 4, due to the elasticity of the spring 13, the L-shaped support plates 9 on both sides will drive the screen 10 to return to its position, thereby reciprocating left and right movement to pre-screen the concentrated magnetic tailings for phosphorus beneficiation. At the same time, the vibration mechanism will vibrate the screen 10 to assist in screening.
[0024] When the first half toothed wheel 8 rotates, the upper half toothed wheel meshes with the first rack 4, which in turn drives the first rack 4 to push the L-shaped support plate 9. When the L-shaped support plate 9 transmits the power to the other L-shaped support plate 9, it will squeeze the spring 13 through the transmission rod 14. When the upper half toothed wheel of the first half toothed wheel 8 does not mesh with the first rack 4, the elastic force of the spring 13 will restore the L-shaped support plates 9 on both sides, causing the screen 10 to return to its position. Compared with traditional devices, this device can make the concentrated magnetic tailings form a multi-dimensional motion trajectory on the screen surface. Compared with a single screening method, this composite motion can make the phosphorus slag in the concentrated magnetic tailings more fully separated from other substances, and can also effectively prevent screen hole clogging, ensuring that phosphorus slag of different particle sizes can be accurately separated according to the screen hole size.
[0025] The slag-separating box 1 is fixedly mounted with a third bracket 21 on its front side. A third motor 22 is fixedly mounted on the inner side of the third bracket 21. A first bevel gear 23 is fixedly mounted on the end of the output shaft of the third motor 22. A first rotating rod 24 is rotatably mounted on the bottom of the slag-separating box 1. A second bevel gear 25 is fixedly mounted on the bottom of the first rotating rod 24 and meshes with the first bevel gear 23. A second rotating rod 27 is rotatably mounted on the front and rear sides of the bottom of the slag-separating box 1. The second rotating rod 27 and the first rotating rod 24 are connected by a first transmission belt 26. The two second rotating rods 27 are connected by a second transmission belt 28. A flexible actuating rod 29 is fixedly mounted on the end of the second rotating rod 27 extending into the slag-separating box 1.
[0026] When the operator starts the third motor 22, the output shaft will drive the first bevel gear 23 to start rotating. When the first bevel gear 23 starts rotating, it will drive the second bevel gear 25 that meshes with it to start rotating. When the second bevel gear 25 rotates, it will drive the first rotating rod 24 to rotate. When the first rotating rod 24 rotates, it will drive the second rotating rod 27 to rotate through the first transmission belt 26. When the second rotating rod 27 rotates, it will drive the second rotating rod 27 on the other side to rotate through the second transmission belt 28. When the second rotating rod 27 rotates, it will drive the flexible actuating rod 29 to start rotating.
[0027] When the first bevel gear 23 starts to rotate, it will drive the second bevel gear 25, which meshes with it, to start rotating. When the second bevel gear 25 rotates, it will drive the first rotating rod 24 to rotate. When the first rotating rod 24 rotates, it will drive the second rotating rod 27 to rotate via the first transmission belt 26. When the second rotating rod 27 rotates, it will drive the second rotating rod 27 on the other side to rotate via the second transmission belt 28. When the second rotating rod 27 rotates, it will drive the flexible actuating rod 29 to start rotating. Compared with traditional devices, this device avoids the accumulation of phosphorus slag in the box and blockage of the screen or other components, thereby ensuring the continuous and efficient operation of the entire slag separation equipment, reducing downtime maintenance time caused by poor slag discharge, and improving production efficiency.
[0028] The vibration mechanism includes a second bracket 15 fixedly installed on the back of the slag-straining box 1, a second motor 16 fixedly installed on the inner side of the second bracket 15, and the output shaft of the second motor 16 extending into the interior of the slag-straining box 1. A second half-toothed gear 17 is fixedly installed at the end of the output shaft of the second motor 16. A hollow fixing block 20 is fixedly installed on the top outer surface of the slag-straining box 1, and the hollow fixing block 20 extends into the interior of the slag-straining box 1. An extension protrusion of an annular sleeve block 19 is slidably installed inside the hollow fixing block 20, and the second half-toothed gear 17 is located inside the annular sleeve block 19. A second rack 18 is fixedly installed on the inner walls of both sides of the annular sleeve block 19, and the second half-toothed gear 17 meshes with it. A rubber block is fixedly installed on the bottom side of the annular sleeve block 19.
[0029] By starting the second motor 16, the output shaft of the second motor 16 will drive the second half toothed gear 17 to start rotating. When the second half toothed gear 17 rotates and meshes with the second rack 18 on the right inner wall of the annular sleeve block 19, it will cause the rubber block on the bottom side of the annular sleeve block 19 to impact the screen 10. When the second half toothed gear 17 rotates and meshes with the second rack 18 on the left inner wall of the annular sleeve block 19, it will cause the extended protrusion of the annular sleeve block 19 to slide into the hollow fixed block 20. At the same time, the rubber block will not contact the screen 10, thus effectively assisting the screen 10 in separating slag.
[0030] Among them, auxiliary screens 11 are fixedly installed on the bottom sides of the two L-shaped support plates 9, and the auxiliary screens 11 are located on the bottom sides of the two L-shaped support plates 9.
[0031] An auxiliary screen 11 is fixedly installed on the bottom side of two L-shaped support plates 9, which can effectively re-select phosphorus from the concentrated magnetic tailings that have leaked slag, thereby increasing the efficiency of slag separation.
[0032] The top of the slag-separating box 1 is fixedly equipped with a discharge trough 31, and the discharge trough 31 has an opening that is larger at the top and smaller at the bottom.
[0033] The feeding chute 31 has an opening that is wider at the top and narrower at the bottom, which makes it easier for workers to transport concentrated magnetic tailings into the slag box 1, thereby improving work efficiency.
[0034] The discharge block 30 is fixedly installed directly below the auxiliary screen 11 inside the slag separator 1, and the discharge block 30 is inclined.
[0035] By tilting the discharge block 30 inside the slag-separating box 1, the slag can be quickly conveyed to the outside through the inclined slope of the discharge block 30, avoiding blockage inside the slag-separating box 1.
[0036] The bottom of the slag-separating box 1 is fixedly installed with a base 32, and the base 32 is located around the bottom of the slag-separating box 1.
[0037] The base 32, which is positioned around the bottom of the slag box 1, effectively provides support for the entire device, increasing its stability.
[0038] Working principle and usage process of this utility model:
[0039] When workers need to pre-screen the concentrated magnetic tailings for phosphorus beneficiation, they simultaneously start the first motor 7 and the vibration mechanism. The output shaft of the first motor 7 will drive the first half toothed gear 8 to start rotating. When the first half toothed gear 8 rotates, the upper half toothed gear meshes with the first rack 4, which will drive the first rack 4 to push the L-shaped support plate 9. When the L-shaped support plate 9 transmits the power to the other L-shaped support plate 9, it will squeeze the spring 13 through the transmission rod 14. When the upper half toothed gear of the first half toothed gear 8 does not mesh with the first rack 4, due to the elasticity of the spring 13, the L-shaped support plates 9 on both sides will drive the screen 10 to return to its position, thereby reciprocating left and right movement to pre-screen the concentrated magnetic tailings for phosphorus beneficiation. At the same time, the vibration mechanism will vibrate the screen 10 to assist in screening.
[0040] When the operator starts the third motor 22, the output shaft will drive the first bevel gear 23 to start rotating. When the first bevel gear 23 starts rotating, it will drive the second bevel gear 25 that meshes with it to start rotating. When the second bevel gear 25 rotates, it will drive the first rotating rod 24 to rotate. When the first rotating rod 24 rotates, it will drive the second rotating rod 27 to rotate through the first transmission belt 26. When the second rotating rod 27 rotates, it will drive the second rotating rod 27 on the other side to rotate through the second transmission belt 28. When the second rotating rod 27 rotates, it will drive the flexible actuating rod 29 to start rotating.
