DETAILED DESCRIPTION

[0046] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0047] See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a slag crushing device for silicon-manganese alloy production, comprising a crushing bin 100, a crushing unit 200, a reciprocating lifting unit 300 and a slag gathering unit 400; a feeding port 110 is provided at the upper end of the crushing bin 100;

[0048] See also Figure 5 The crushing unit 200 is disposed in the crushing bin 100 and includes a lifting plate 220 which is liftably disposed in the crushing bin 100, and a hammer head 240 is installed at the lower end of the lifting plate 220;

[0049] See also Figure 4 , the reciprocating lifting unit 300 is arranged in the crushing chamber 100, and is used to lift the lifting plate 220 and the hammer head 240 to a preset height and release them;

[0050] See also Figure 7The slag gathering units 400 are provided with multiple groups and circumferentially distributed in the crushing bin 100, including a second mounting frame 410 fixed on the inner wall of the crushing bin 100, a swing rod 420 rotatably connected to the second mounting frame 410, and a flip driving member for driving the swing rod 420, and an arc-shaped shoveling plate 430 is fixed at one end of the swing rod 420 away from the second mounting frame 410;

[0051] When the hammer head 240 is released from a preset height and falls freely, the impact generated by the hammer head 240 is used to crush the slag at the center of the crushing bin 100; when the reciprocating lifting unit 300 lifts the lifting plate 220 and the hammer head 240 to the preset height, the flipping drive component is triggered to drive the rocker arm 420 to flip toward the center of the crushing bin 100, driving the arc-shaped shovel plate 430 to gather the large particles of slag on the periphery toward the center of the crushing bin 100.

[0052] Specifically, the slag is fed into the crushing bin 100 from the feeding port 110, and the lifting plate 220 is driven to move upward by the reciprocating lifting unit 300 until the hammer head 240 is lifted to a set height, and then the lifting plate 220 is released, and the hammer head 240 can fall freely under the action of its own gravity, and the slag is hammered and crushed by the kinetic energy impact generated when the hammer head 240 falls; each time the hammer head 240 falls and hammers, the slag at the center of the crushing bin 100 will spread outward under the squeezing action of the hammer head 240, and the slag at the periphery will be crushed. The slag is further pushed outward; when the reciprocating lifting unit 300 lifts the lifting plate 220 and the hammer head 240 upward again, the flipping drive component is triggered to drive the rocker arm 420 to flip toward the center of the crushing bin 100, thereby driving the arc-shaped shoveling plate 430 to move, and the slag pushed to the outside is shoveled up and gathered together toward the center of the crushing bin 100, so that it is convenient for the hammer head 240 to crush the large-particle slag that has not been hammered in the next cycle, which can effectively improve the slag crushing efficiency and the particle size uniformity of the crushed product.

[0053] It should be noted that the above-mentioned preset height is not specifically limited and can be set according to the specifications of the crushing bin 100 and actual working conditions.

[0054] In one embodiment, see Figure 5 The crushing unit 200 further includes lifting guide rails 210 symmetrically and vertically mounted on the inner walls of both sides of the crushing bin 100, and both ends of the lifting plate 220 are provided with lifting slide bars 230 slidably matched with the corresponding lifting guide rails 210;

[0055] When the reciprocating lifting unit 300 drives the lifting plate 220 to rise vertically or the hammer head 240 to fall freely, the lifting slide bar 230 slides along the corresponding lifting guide rail 210, and the moving path of the hammer head 240 is guided and limited by the lifting guide rail 210, thereby ensuring that the hammer head 240 can act on the center of the crushing bin 100 every time it falls, so as to ensure the stability of the hammer crushing effect.

[0056] For further information, see Figure 6 In order to improve the hammering and crushing effect of the hammer head 240, a cavity 241 is provided in the hammer head 240, and a weight ball 242 is arranged in the cavity 241. The weight ball 242 is suspended in the cavity 241 through a plurality of elastic cables 243 distributed in the circumferential direction;

[0057] When the hammer head 240 falls freely and hammers the slag, the built-in counterweight ball 242 can not only increase the weight of the hammer head 240, thereby increasing its inertia, so that the hammer head 240 has greater kinetic energy during the hammering process, thereby improving the crushing effect; but also the counterweight ball 242 suspended in the cavity 241 by the elastic cable 243 can effectively absorb the rebound force generated by the hammer head 240 when hammering the slag, reduce the reverse impact force of the hammer head 240, and at the same time reduce the vibration of the entire equipment when the hammer head 240 hits, thereby reducing noise and extending the service life.

[0058] In yet another embodiment, see Figure 7 The flip driving member includes a flip cylinder 440 rotatably mounted on the second mounting frame 410 and a driving box 450 fixed on the inner wall of the crushing chamber 100. The second mounting frame 410 is provided with a through slot 411 for accommodating the flip cylinder 440. One end of the flip cylinder 440 away from the second mounting frame 410 is hinged to the swing rod 420. An air pipe 470 is connected between the driving box 450 and the flip cylinder 440. The driving box 450 is provided with a jacking driving member 460 adapted to the lifting plate 220.

[0059] When the lifting plate 220 is lifted vertically, the lifting driving member 460 triggers the driving box 450 to blow air into the flip cylinder 440 through the air pipe 470, so as to drive the piston rod of the flip cylinder 440 to extend and push the swing rod 420 to flip;

[0060] Specifically, when the lifting plate 220 moves upward, the lifting drive member 460 is actuated, thereby squeezing the gas in the drive box 450 into the flip cylinder 440 through the air pipe 470, thereby pushing the piston rod out, and then driving the swing arm 420 to swing toward the center of the crushing bin 100, so as to drive the arc-shaped shovel plate 430 to gather the large particles of slag on the periphery to the center.

[0061] It should be noted that there is no restriction on the triggering timing of the lifting plate 220 on the jacking drive member 460. It can be triggered during the rising process of the lifting plate 220, or it can be triggered after the lifting plate 220 reaches a preset height, as long as it does not affect the normal operation of the slag gathering unit 400. In other words, when the jacking drive member 460 generates a triggering action, the hammer head 240 will not interfere with the arc-shaped shoveling plate 430 and the reciprocating lifting unit 300.

[0062] For further information, see Figure 8 The driving box 450 includes a box body 451 fixed on the crushing chamber 100, and a partition 452 is arranged in the box body 451. The partition 452 divides the inside of the box body 451 into a first chamber 453 and a second chamber 454. The volume of the first chamber 453 is greater than the volume of the second chamber 454. An air passage 455 is connected between the first chamber 453 and the second chamber 454. The lifting driving member 460 is arranged in the first chamber 453, and the second chamber 454 is connected to the air pipe 470.

[0063] Specifically, when the lifting plate 220 triggers the lifting drive 460 to produce a triggering action, the air in the first chamber 453 is squeezed, so that the air enters the second chamber 454 through the air channel 455, and then enters the flip cylinder 440 through the air pipe 470, so as to drive the piston rod of the flip cylinder 440 to extend and drive the rocker arm 420 to flip.

[0064] It should be noted that since the volume of the first chamber 453 is greater than that of the second chamber 454, and the heights of the first chamber 453 and the second chamber 454 are the same, the cross-sectional area of ​​the first chamber 453 is greater than that of the second chamber 454. In this way, the lifting plate 220 drives the piston plate 461 to slide upward a relatively small distance, so that a relatively large amount of air can be squeezed into the flip cylinder 440, so that the piston rod of the flip cylinder 440 produces a relatively large extension displacement, thereby ensuring that the arc-shaped shovel plate 430 can be driven to quickly produce a large-amplitude flipping action in a short period of time, so as to throw the large particles of slag on the periphery to the center of the crushing bin 100, thereby improving the gathering effect of the slag.

[0065] For further information, see Figure 8 The lifting driving member 460 includes a piston plate 461 slidably disposed in the first chamber 453, a push rod 462 vertically penetrating the box body 451 is fixed to the lower end surface of the piston plate 461, a top plate 463 is fixed to the lower end of the push rod 462, a second spring 464 is disposed between the top plate 463 and the box body 451, and the second spring 464 is movably sleeved on the push rod 462;

[0066] Correspondingly, the lifting plate 220 is provided with a push plate 221 adapted to the top plate 463;

[0067] Specifically, when the lifting plate 220 rises vertically, the push plate 221 on the lifting plate 220 contacts the top plate 463, thereby pushing the top plate 463 to rise synchronously, and then pushing the piston plate 461 to move upward in the first chamber 453 through the push rod 462, and the second spring 464 is compressed to squeeze out the air in the first chamber 453, and then the squeezed air passes through the second chamber 454 and the air pipe 470 in sequence and enters the flip cylinder 440;

[0068] When the lifting plate 220 reaches the preset height, the piston plate 461 also reaches its upper travel limit, thereby ensuring that enough air in the first chamber 453 is squeezed out to drive the arc-shaped scraping plate 430 to flip;

[0069] When the lifting plate 220 starts to fall freely from a preset height, the top plate 463 also moves downward under the elastic force of the second spring 464, thereby driving the piston plate 461 to slide down and reset, so that negative pressure is generated in the first chamber 453, and then the air in the flip cylinder 440 flows back to the first chamber 453 again, and the piston rod of the flip cylinder 440 retracts, thereby driving the rocker arm 420 and the arc-shaped shovel plate 430 to rotate and reset.

[0070] In further embodiments, see Fig. 9 and Fig.10 The reciprocating lifting unit 300 includes a first mounting frame 310 fixed on the inner wall of the crushing bin 100 and a driven shaft 330 rotatably mounted on the inner wall of the crushing bin 100, a driving shaft 320 is rotatably mounted on the first mounting frame 310, a lifting belt 340 is vertically rotatably connected between the driving shaft 320 and the driven shaft 330, and a lifting member 350 adapted to the lifting plate 220 is detachably mounted on the lifting belt 340; a driving motor 360 is mounted on the top of the crushing bin 100, and a transmission belt 370 is connected between the output end of the driving motor 360 and the driving shaft 320;

[0071] Specifically, under the transmission of the transmission belt 370, the driving motor 360 drives the driving shaft 320 to rotate, thereby driving the lifting belt 340 to move; when the lifting member 350 on the lifting belt 340 rises vertically from under the lifting plate 220 and contacts the lower end surface of the lifting plate 220, it can drive the lifting plate 220 to rise synchronously to lift the hammer head 240 to a preset height.

[0072] Further, considering that after the lifting member 350 lifts the lifting plate 220 to a preset height, the lifting member 350 needs to be separated from the lifting plate 220, so that the lifting plate 220 can fall freely under the action of gravity to achieve the subsequent hammering action of the hammer head 240; for this purpose, the lifting member 350 includes a mounting platform 351 fixedly connected to the belt surface of the lifting belt 340 and a lifting plate 353 rotatably connected to the mounting platform 351, and a limiting plate 352 is provided on one side of the mounting platform 351 facing the movement direction of the lifting belt 340, and the limiting plate 352 is used to limit the flipping angle of the lifting plate 353;

[0073] See also Fig. 9 A locking member 380 for locking the lifting plate 353 is also provided on one side of the mounting platform 351; when the lifting plate 220 reaches a preset height, the locking member 380 releases the locking effect on the lifting plate 353;

[0074] When the lifting plate 353 is in the vertical direction, the lifting plate 353 is in the vertical direction, and the lifting plate 353 is in the vertical direction, so that the lifting plate 353 can not rotate relative to the mounting platform 351.

[0075] See also Fig.10 and Fig.11 The locking member 380 includes a sleeve plate 381 fixed on the limit plate 352, a sliding column 382 is slidably arranged in the sleeve plate 381, a limit block 383 and a magnetic block 386 are respectively fixed at both ends of the sliding column 382, ​​a wedge block 384 is arranged on the side of the limit block 383 facing the lifting plate 353, and a wedge groove 387 adapted to the wedge block 384 is opened on the lifting plate 353; a first spring 385 is arranged between the sleeve plate 381 and the limit block 383, and the first spring 385 is movably sleeved on the sliding column 382;

[0076] Accordingly, see Fig. 9 , a bracket 311 is provided on the first mounting frame 310, and an electromagnet 312 adapted to the magnetic suction block 386 is installed on the bracket 311;

[0077] Specifically, see Fig. 9, Fig.10 , Fig.11 and Fig.12 When the lifting plate 220 reaches the preset height, the magnetic block 386 in the locking member 380 just reaches the same height as the electromagnet 312, and the electromagnet 312 attracts the magnetic block 386, thereby driving the slide column 382 to slide relative to the sleeve 381 toward the side away from the lifting plate 353, and the first spring 385 is compressed, so that the wedge block 384 moves out of the wedge groove 387 of the lifting plate 353 to release the locking effect on the lifting plate 353, so that the lifting plate 353 turns downward under its own gravity and separates from the lifting plate 220;

[0078] As the lifting belt 340 continues to run, the magnetic block 386 gradually moves upward and staggers with the electromagnet 312 until the magnetic block 386 is completely separated from the electromagnet 312 and the magnetic block 386 is no longer magnetically attracted. As a result, under the elastic force of the first spring 385, the slide column 382 slides toward one side of the lifting plate 353 and returns to its original position. When the entire lifting member 350 follows the lifting belt 340 to bypass the top of the drive shaft 320 and flips to the side away from the reciprocating lifting unit 300, the limit plate 353 is 2 is located below the lifting plate 353. The lifting plate 353 turns downward under its own gravity until it fits with the limiting plate 352. During the downward turning process of the lifting plate 353, the lifting plate 353 temporarily presses the wedge surface of the wedge block 384, so that the sliding column 382 temporarily moves away from the lifting plate 353. When the lifting plate 353 is completely turned to a horizontal posture, the wedge block 384 can be inserted into the wedge groove 387 again under the elastic force of the first spring 385, so as to realize the locking of the lifting plate 353 again.

[0079] In another embodiment, a slag crushing system for silicon-manganese alloy production is provided, which includes the slag crushing device for silicon-manganese alloy production in the aforementioned embodiment, and in addition, includes but is not limited to the following components:

[0080] Feeding device: used to feed the slag into the crushing device evenly and continuously, which may include a vibrating feeder or other types of feeding equipment to ensure smooth flow of slag and avoid blockage;

[0081] Discharging device: quickly discharge the crushed slag, which can be a conveyor belt, screw conveyor or other types of discharging equipment to transport the crushed slag to the next process or storage area;

[0083] Safety protection devices: including emergency stop button, protective cover, safety interlock, etc. to ensure the safety of operators.

[0084] In this embodiment, a slag crushing method for silicon-manganese alloy production is also provided, comprising the following steps:

[0089] S5. Repeat steps S2-S4 until the slag reaches a preset particle size.
