Technical Field
[0001] This utility model relates to the technical field of steel slag grinding mills that facilitate control of the crushed particle size, and in particular to a steel slag grinding mill that facilitates control of the crushed particle size. Background Technology
[0002] A grinding mill is a device that grinds solids into powder. It is often used to grind steel slag. It mainly consists of a grinding mill and crushing rollers. The steel slag is poured into the inside of the grinding mill through the feed inlet, and the grinding rollers are started to rotate, thereby crushing the steel slag into powder.
[0003] The inventors discovered during routine use of a grinding mill that the distance between the grinding rollers in a typical grinding mill is the same. This makes it impossible to adjust the distance between the grinding rollers, which in turn prevents the adjustment of the particle size of the steel slag after grinding. Consequently, the steel slag can only be ground into powder of the same particle size, which has an impact. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel slag grinding mill that facilitates control of the crushed particle size.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel slag grinding mill for easy control of particle size, comprising a grinding mill, a feed frame fixedly connected to the top of the grinding mill, a filter plate fixedly connected inside the grinding mill, a crushing roller rotatably connected inside the grinding mill, a motor arranged on the side of the grinding mill, a crushing roller fixedly connected to the output end of the motor, an ejection device arranged inside the grinding mill, a collection frame fixedly connected to the side of the grinding mill, an auger fixedly connected inside the collection frame, an adjustment device arranged on the side of the grinding mill, the adjustment device comprising a through groove opened on the side of the grinding mill, a rotating shaft arranged inside the through groove, a ring sleeved on the surface of the rotating shaft, a threaded rod threadedly connected inside the through groove, and a ring rotatably connected to one end of the threaded rod.
[0006] The effect achieved by the above components is as follows: under the action of the threaded rod, the distance between the crushing rollers can be adjusted, thereby achieving the adjustment function. When it is necessary to grind the steel slag, the steel slag is poured into the inside of the grinding mill through the feed frame. The motor is started, which makes the crushing rollers rotate, thereby crushing the steel slag and causing it to fall onto the surface of the filter plate. The smaller particles fall into the bottom of the grinding mill through the filter plate, while the larger particles fall into the inside of the collection frame through the opening on the side of the grinding mill. The large pieces of steel slag are then transported back into the inside of the feed frame for crushing by the auger.
[0007] Preferably, the inner wall of the through groove is provided with an elongated groove, and a rectangular block is slidably connected inside the elongated groove. One side of the rectangular block is fixedly connected to the surface of the ring.
[0008] The effect achieved by the above components is that, under the action of the rectangular block, the ring can move freely inside the through groove.
[0009] Preferably, the ring has a groove inside, and a ball bearing is rotatably connected inside the groove.
[0010] The effect achieved by the above components is that, under the action of the ball bearings, the friction between the motor output end and the ring is reduced, thus facilitating rotation.
[0011] Preferably, the side of the grinding mill is provided with a groove, a fixed rod is fixedly connected inside the groove, a slider is slidably connected to the surface of the fixed rod, and one end of the slider is fixedly connected to the side of the motor.
[0012] The effect achieved by the above components is as follows: under the action of the slider, the motor can adjust its position by following the movement of the slider. When it is necessary to adjust the distance between the crushing rollers, the threaded rod is turned by hand, so that the ring can move inside the through groove. Under the action of the rectangular block, the ring can move freely inside the through groove. At the same time, under the action of the slider, the motor can adjust its position by following the movement of the slider. After the adjustment is completed, the motor is started, so that the output end of the motor rotates inside the ring. Under the action of the ball bearings, the friction between the output end of the motor and the ring is reduced, thus facilitating rotation and achieving the effect of adjusting the distance between the crushing rollers.
[0013] Preferably, the ejection device includes a drive motor fixedly connected to the side of the grinding mill, a first rectangular groove is provided inside the grinding mill, a screw is rotatably connected inside the first rectangular groove, a first sliding block is threadedly connected to the surface of the screw, and a triangular push plate is fixedly connected to the side of the first sliding block.
[0014] The effect achieved by the above components is that, under the action of the screw, the triangular pusher plate can push the steel slag that is stopped on the surface of the filter plate out, thereby achieving the function of pushing it out.
[0015] Preferably, a round rod is fixedly connected inside the rectangular groove, and a second sliding block is slidably connected to the surface of the round rod. The side of the second sliding block is fixedly connected to the triangular push plate.
[0016] The effect achieved by the above components is that, under the action of the round rod, the triangular pusher plate can move smoothly on the surface of the filter plate.
[0017] Preferably, a rectangular strip, which is a rubber strip, is fixedly connected to the surface of the triangular push plate.
[0018] The effect achieved by the above components is that, under the action of the rectangular bars, the triangular push plate will not come into direct contact with the steel slag, thus avoiding the phenomenon of rigid contact.
[0019] Preferably, the grinding mill has a second rectangular groove inside, a long rod is fixedly connected inside the second rectangular groove, a rectangular plate is slidably connected to the surface of the long rod, bristles are fixedly connected to the surface of the rectangular plate, and a magnetic block is fixedly connected to the upper top of the rectangular plate and the lower surface of the triangular push plate.
[0020] The aforementioned components achieve the following effects: Under the attraction of the positive and negative poles of the magnetic blocks, the bristles adhere tightly to the bottom of the filter plate, thereby pushing out the steel slag inside the filter plate mesh. They also move along with the triangular pusher plate. When too much steel slag remains on the filter plate surface, the drive motor is activated, causing the screw to rotate and move the triangular pusher plate across the screw surface. The round rod ensures the triangular pusher plate moves smoothly across the filter plate surface. The rectangular bar prevents direct contact between the triangular pusher plate and the steel slag, avoiding rigid contact. The attraction of the positive and negative poles of the magnetic blocks allows the bristles to adhere tightly to the bottom of the filter plate, pushing out the steel slag inside the filter plate mesh. Simultaneously, the rectangular long plate slides on the surface of the long rod, moving along with the triangular pusher plate, thus achieving the pushing effect.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an adjustment device, when it is necessary to adjust the distance between the crushing rollers, the threaded rod is turned by hand, allowing the ring to move inside the through groove. Under the action of the rectangular block, the ring can move freely inside the through groove. At the same time, under the action of the slider, the motor can adjust its position by following the movement of the slider. After the adjustment is completed, the motor is started, causing the output end of the motor to rotate inside the ring. Under the action of the ball bearings, the friction between the output end of the motor and the ring is reduced, thus facilitating rotation. This achieves the function of adjusting the distance between the crushing rollers, thereby solving the problem that the grinding mill cannot grind steel slag into powder of different particle sizes.

[0028] Example 1, as Figure 1-4 As shown, a steel slag grinding mill 1 with easily controllable particle size includes a grinding mill 1, a feed frame 5 fixedly connected to the top of the grinding mill 1, a filter plate fixedly connected inside the grinding mill 1, a crushing roller rotatably connected inside the grinding mill 1, a motor 4 installed on the side of the grinding mill 1, the output end of the motor 4 fixedly connected to the crushing roller, an ejection device 3 installed inside the grinding mill 1, a collection frame 7 fixedly connected to the side of the grinding mill 1, an auger 6 fixedly connected inside the collection frame 7, and an adjustment device 2 installed on the side of the grinding mill 1. When steel slag needs to be ground, the steel slag is poured into the grinding mill 1 through the feed frame 5, the motor 4 is started, causing the crushing roller to rotate, thereby crushing the steel slag and causing it to fall onto the surface of the filter plate. The smaller particles fall to the bottom of the grinding mill 1 through the filter plate, while the larger particles fall into the collection frame 7 through the opening on the side of the grinding mill 1. The auger 6 then transports the large pieces of steel slag back to the feed frame 5 for crushing.
[0029] Reference Figure 2The adjusting device 2 includes a through groove 21 on the side of the grinding mill 1. A rotating shaft is installed inside the through groove 21, and a ring 24 is fitted on the surface of the rotating shaft. A threaded rod 23 is threadedly connected inside the through groove 21. One end of the threaded rod 23 is rotatably connected to the ring 24. Under the action of the threaded rod 23, the distance between the crushing rollers can be adjusted, thereby achieving the adjustment function. When it is necessary to grind the steel slag, the steel slag is poured into the inside of the grinding mill 1 through the feed frame 5, the motor 4 is started, and the crushing rollers are rotated, thereby crushing the steel slag and causing it to fall. On the surface of the filter plate, small particles fall into the bottom of the grinding mill 1 through the filter plate, while large particles fall into the collection frame 7 through the opening on the side of the grinding mill 1. The large pieces of steel slag are then transported back to the feed frame 5 for crushing by the auger 6. The inner wall of the through trough 21 has a long groove 22, and a rectangular block 26 is slidably connected inside the long groove 22. One side of the rectangular block 26 is fixedly connected to the surface of the ring 24. Under the action of the rectangular block 26, the ring 24 can move freely inside the through trough 21. The inside of the ring 24 has a circular... The groove has a rotating ball bearing 25 inside. The ball bearing 25 reduces the friction between the output end of the motor 4 and the ring 24, facilitating rotation. A groove 27 is provided on the side of the mill 1. A fixed rod 29 is fixedly connected inside the groove 27. A slider 28 is slidably connected to the surface of the fixed rod 29. One end of the slider 28 is fixedly connected to the side of the motor 4. The motor 4 can adjust its position by following the movement of the slider 28. When the distance between the grinding rollers needs to be adjusted, the thread is turned by hand. Rod 23 allows the ring 24 to move inside the through groove 21. Under the action of rectangular block 26, the ring 24 can move freely inside the through groove 21. At the same time, under the action of slider 28, the motor 4 can adjust its position by following the movement of slider 28. After adjustment, the motor 4 is started, so that the output end of the motor 4 rotates inside the ring 24. Under the action of ball bearing 25, the friction between the output end of the motor 4 and the ring 24 is reduced, which facilitates rotation and thus achieves the function of adjusting the gap between the crushing rollers.
[0030] Reference Figure 3-4The ejection device 3 includes a drive motor 31 fixedly connected to the side of the grinding mill 1. The grinding mill 1 has a first rectangular groove inside, with a screw 32 rotatably connected inside. A first sliding block is threaded onto the surface of the screw 32, and a triangular push plate 33 is fixedly connected to the side of the first sliding block. Under the action of the screw 32, the triangular push plate 33 can push the steel slag resting on the filter plate surface, thus achieving the ejection function. A round rod 38 is fixedly connected inside the first rectangular groove, with a second sliding block slidably connected to the surface of the round rod 38. The side of the second sliding block is fixedly connected to the triangular push plate 33, allowing the triangular push plate 33 to move smoothly on the filter plate surface under the action of the round rod 38. A rectangular strip 34, made of rubber, is fixedly connected to the surface of the triangular push plate 33, preventing direct contact between the triangular push plate 33 and the steel slag, thus avoiding rigid contact. The grinding mill 1 has a second rectangular groove inside, with a long rod 39 fixedly connected inside. A rectangular strip 34 is slidably connected to the surface of the long rod 39. A rectangular plate 36 has bristles 37 fixedly connected to its surface. A magnetic block 35 is fixedly connected to the top of the rectangular plate 36 and the lower surface of the triangular push plate 33. Under the attraction of the positive and negative poles of the magnetic block 35, the bristles 37 can adhere tightly to the bottom of the filter plate, thus pushing out the steel slag inside the filter plate mesh. They can also move with the triangular push plate 33. When too much steel slag remains on the filter plate surface, the drive motor 31 is activated, causing the screw 32 to rotate, which in turn moves the triangular push plate 33 along the surface of the screw 32. The movement of the round rod 38 allows the triangular pusher 33 to move smoothly on the surface of the filter plate. The rectangular bar 34 prevents the triangular pusher 33 from directly contacting the steel slag, avoiding rigid contact. The attraction between the positive and negative poles of the magnetic block 35 allows the bristles 37 to adhere tightly to the bottom of the filter plate, thereby pushing out the steel slag inside the filter plate mesh. At the same time, the rectangular long plate 36 slides on the surface of the long rod 39 and moves along with the triangular pusher 33, thus achieving the pushing effect.
[0031] Working principle: When using the steel slag grinding mill 1, which allows for easy control of particle size, the steel slag is poured into the mill 1 through the feed frame 5. The motor 4 is started, causing the grinding rollers to rotate, thus crushing the steel slag onto the surface of the filter plate. Smaller particles fall to the bottom of the mill 1 through the filter plate, while larger particles fall into the collection frame 7 through the opening on the side of the mill 1. The auger 6 then transports the larger pieces of steel slag back to the feed frame 5 for further crushing. When adjusting the distance between the grinding rollers, the threaded rod 23 is turned by hand, allowing the ring 24 to move within the through groove 21. Under the action of the rectangular block 26, the ring 24 can move freely within the through groove 21. Simultaneously, under the action of the slider 28, the motor 4 can adjust its position by following the movement of the slider 28. After adjustment, the motor 4 is started, causing the motor 4 to... The output end rotates inside the ring 24. Under the action of the ball 25, the friction between the output end of the motor 4 and the ring 24 is reduced, making it easier to rotate and thus achieving the function of adjusting the gap between the crushing rollers. When too much steel slag remains on the surface of the filter plate, the drive motor 31 is started, causing the screw 32 to rotate, which in turn drives the triangular push plate 33 to move on the surface of the screw 32. Under the action of the round rod 38, the triangular push plate 33 can move smoothly on the surface of the filter plate. Under the action of the rectangular bar 34, the triangular push plate 33 will not directly contact the steel slag, avoiding the phenomenon of rigid contact. Under the attraction of the positive and negative poles of the magnetic block 35, the bristles 37 can stick tightly to the bottom of the filter plate, thus pushing out the steel slag inside the filter plate mesh. At the same time, the rectangular long plate 36 slides on the surface of the long rod 39 and moves with the triangular push plate 33, thus achieving the function of pushing out.
