Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a ball mill for steel slag. Background Technology

[0002] Steel slag, an indispensable industrial byproduct of steelmaking, is formed from a series of complex physicochemical reactions between impurities in the raw steel and specially added slag-forming materials in a high-temperature furnace. The resulting slag is discharged after steelmaking and cooled and solidified, eventually transforming into what we call steel slag. Steel slag is rich in various valuable elements and compounds, but if not properly treated, traditional dumping or landfilling methods not only occupy a large amount of valuable land resources but also pose a potential long-term pollution threat to the surrounding environment due to the heavy metals and other harmful substances it contains. Therefore, steel slag ball mills are needed to grind steel slag. Steel slag ball mills can effectively refine steel slag materials into smaller particles. This process not only helps to improve the subsequent utilization rate of steel slag, such as as building materials, road paving materials, or metallurgical raw materials, but also significantly reduces its negative impact on the environment, achieving sustainable recycling of resources.

[0003] Existing equipment has some drawbacks during use. For example, in the steel slag grinding process, existing ball mills are usually equipped with baffles to divide the equipment into a coarse processing zone and a fine processing zone to ensure that larger steel slag particles do not enter the fine processing zone, thus affecting the grinding effect and product quality. However, after long-term use, the channels on the baffles will become blocked. The blockage of the channels will hinder the smooth flow of steel slag particles, resulting in a decrease in grinding efficiency. The material in the coarse processing zone cannot enter the fine processing zone in time, affecting the overall grinding progress. Utility Model Content

[0004] The purpose of this invention is to provide a ball mill specifically for steel slag, which solves the problem that the through grooves on the partition plate will become clogged, thus affecting the overall grinding progress.

[0005] This utility model provides the following technical solution: a ball mill for steel slag, comprising:

[0006] Two support bases;

[0007] A housing, wherein the housing is disposed between two support bases;

[0008] A partition is fixedly connected to the inner wall of the housing. The interior of the housing is divided into a roughing cavity and a finishing cavity by the partition. Multiple steel balls are arranged inside both the roughing cavity and the finishing cavity. Multiple through slots are arranged in a ring array on the partition.

[0009] The inlet and outlet are provided. The inlet is fixedly connected to the outer wall of one side of the housing and communicates with the roughing chamber. The outlet is fixedly connected to the outer wall of the housing away from the inlet and communicates with the finishing chamber. The inlet and outlet are symmetrically arranged. The ends of the inlet and outlet away from the housing pass through the corresponding support seats laterally and are rotatably connected to the corresponding support seats.

[0010] A drive assembly, which is disposed on the housing and is used to drive the housing to rotate;

[0011] An anti-clogging component is disposed on a partition plate and is used to prevent the through grooves on the partition plate from clogging the steel slag.

[0012] In the above scheme, the housing is started to rotate by the drive component. As the housing rotates, the steel balls in the roughing chamber and the finishing chamber will be subjected to centrifugal force and begin to grind the added steel slag. When the through groove on the partition is blocked by steel slag, the anti-blocking component removes the blocked steel slag to ensure the continuity of the grinding process.

[0013] As a preferred embodiment of the above technical solution, the drive assembly includes an external gear fixedly connected to the outer wall of the housing near the feed inlet, a support plate fixedly connected to the bottom of one of the mounting bases near the outer wall of the housing, a first motor fixedly connected to the upper surface of the support plate, a transmission shaft fixedly connected to the output end of the first motor, and a drive gear fixedly sleeved on the outer side of the end of the transmission shaft away from the first motor, the drive gear meshing with the external gear.

[0014] In the above scheme, the gear transmission has the characteristics of accurate transmission ratio and smooth operation. The meshing of the driving gear and the external gear ensures the smoothness of the housing rotation and improves the grinding quality.

[0015] As a preferred embodiment of the above technical solution, the anti-clogging component includes a placement cavity opened inside the partition, a movable ring slidably connected to the inner side of the placement cavity, an installation frame provided inside the movable ring, and sliding rods slidably sleeved at the four corners of the installation frame, with the two ends of the four sliding rods respectively fixedly connected to the inner sidewall of the movable ring.

[0016] In the above scheme, the sliding connection design between the slide bar and the mounting frame helps to reduce direct friction between components, thereby reducing wear.

[0017] As a preferred embodiment of the above technical solution, the anti-clogging component further includes a bidirectional motor fixedly installed inside the mounting frame. Two output ends of the bidirectional motor are fixedly connected to rotating shafts. A swing block is fixedly sleeved on the outer side of the two rotating shafts away from the bidirectional motor. Upper springs are sleeved on the outer side of the top of the four sliding rods, and lower springs are sleeved on the outer side of the bottom of the four sliding rods. The four upper springs are located between the inner wall of the moving ring and the upper end face of the mounting frame, and the four lower springs are located between the inner wall of the moving ring and the lower end face of the mounting frame. First springs are fixedly connected to the outer walls of the opposite sides of the moving ring. The ends of the two first springs away from the moving ring are fixedly connected to the inner wall of the placement cavity. Hammers are fixedly connected to the outer walls of the opposite sides of the mounting frame.

[0018] In the above scheme, the upper and lower springs are set on the slide rod, which provides stable support and buffer for the sliding of the mounting frame.

[0019] As a preferred embodiment of the above technical solution, the inner sidewall of the roughing cavity is provided with a ring array of multiple corrugated liners, and the inner sidewall of the finishing cavity is provided with a ring array of multiple flat liners. The multiple corrugated liners and the multiple flat liners are all fixedly connected to the housing by bolts.

[0020] In the above scheme, the design of the corrugated liner can change the flow state of the material in the roughing chamber, increase the contact area and collision opportunities between the steel slag and the steel ball, thereby improving the grinding efficiency. The flat liner helps the steel slag to flow smoothly in the finishing chamber, reducing eddies and dead corners, and improving the processing accuracy and product quality.

[0021] As a preferred embodiment of the above technical solution, a first connecting groove is provided on the outer wall of the housing corresponding to the rough machining cavity, and a second connecting groove is provided on the outer wall of the housing corresponding to the fine machining cavity. A first cover plate and a second cover plate are respectively provided on the outer wall of the housing corresponding to the first connecting groove and the second connecting groove, and the first cover plate and the second cover plate are respectively used to cover the first connecting groove and the second connecting groove. The first cover plate and the second cover plate are both fixedly connected to the housing by bolts.

[0022] In the above scheme, the steel ball can be placed into the roughing cavity and the finishing cavity by simply opening the first cover plate and the second cover plate.

[0023] As a preferred embodiment of the above technical solution, the inner walls of both the inlet and outlet are fixedly connected with multiple discharge plates in a ring array, and the multiple discharge plates are spirally arranged.

[0024] In the above scheme, the spiral-shaped discharge plate can guide the material to form an orderly flow at the inlet and outlet, reducing the possibility of material blockage and stagnation.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In this invention, a bidirectional motor is started to drive the swing block to rotate. The centrifugal force generated by the swing block pushes the mounting frame and the hammer head connected to it to slide on the slide rod. At the same time, the moving ring slides left and right in the placement cavity. Combined with the buffering effect of the upper spring, lower spring and first spring, the hammer head strikes the partition plate, causing the partition plate to vibrate. This vibration effectively shakes out the blockage in the through groove, restoring the smooth flow between the roughing cavity and the finishing cavity, thereby ensuring the smooth flow of steel slag particles and the stability of grinding efficiency.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0035] Example

[0036] like Figures 1-5 As shown, this utility model provides a technical solution: a ball mill for steel slag, comprising: two support bases 10; a shell 11 disposed between the two support bases 10; a partition 12 fixedly connected to the inner wall of the shell 11, the shell 11 being divided by the partition 12 to form a roughing chamber and a finishing chamber, both the roughing chamber and the finishing chamber containing multiple steel balls, and the partition 12 having multiple through slots 15 arranged in a ring array; a feed inlet 16 and a discharge outlet 17, the feed inlet 16 being fixedly connected to one side of the outer wall of the shell 11 and connected to the roughing chamber. The discharge port 17 is fixedly connected to the outer wall of the housing 11 on the side away from the feed port 16 and communicates with the finishing cavity. The feed port 16 and the discharge port 17 are symmetrically arranged. The ends of the feed port 16 and the discharge port 17 away from the housing 11 pass through the corresponding support base 10 laterally and are rotatably connected to the corresponding support base 10. The drive assembly 2 is set on the housing 11 and is used to drive the housing 11 to rotate. The anti-blocking assembly 3 is set on the partition plate 12 and is used to prevent the through groove 15 on the partition plate 12 from blocking the steel slag. Multiple corrugated liners 40 are arranged in a ring array on the inner sidewall of the roughing cavity, and multiple flat liners 41 are arranged in a ring array on the inner sidewall of the finishing cavity. Both the corrugated liners 40 and the flat liners 41 are fixedly connected to the housing 11 by bolts. A first connecting groove 50 is formed on the outer sidewall of the housing 11 corresponding to the position of the roughing cavity, and a second connecting groove 51 is formed on the outer sidewall of the housing 11 corresponding to the position of the finishing cavity. A first cover plate 52 and a second cover plate 53 are respectively provided on the outer sidewall of the housing 11 corresponding to the positions of the first connecting groove 50 and the second connecting groove 51, and the first cover plate 52 and the second cover plate 53 are used to cover the first connecting groove 50 and the second connecting groove 51, respectively. Both the first cover plate 52 and the second cover plate 53 are fixedly connected to the housing 11 by bolts. Multiple discharge plates 60 are fixedly connected in a ring array on the inner sidewall of the inlet 16 and the outlet 17, and the multiple discharge plates 60 are spirally arranged. In actual use, ... Open the first cover plate 52 and the second cover plate 53 to put the steel balls into the roughing chamber and the finishing chamber. After the balls are put in, close the first cover plate 52 and the second cover plate 53. Drive the housing 11 to start rotating. Add steel slag into the roughing chamber through the feed port 16. As the housing 11 rotates, the steel balls in the roughing chamber and the finishing chamber will be subjected to centrifugal force and begin to grind the steel slag. The corrugated liner 40 in the roughing chamber will increase the impact force and frequency of the steel balls on the steel slag, achieving rapid crushing. The initially crushed steel slag enters the finishing chamber through the through groove 15 on the partition plate 12, while the flat liner 41 in the finishing chamber helps to achieve a finer grinding effect. When the through groove 15 on the partition plate 12 is blocked by steel slag, the anti-blocking component 3 removes the blocked steel slag. The ground steel slag is discharged through the discharge port 17. The spirally arranged discharge plate 60 helps the steel slag enter or exit the housing 11.

[0037] As one implementation method in this embodiment, such as Figure 1 and Figure 5 As shown, the drive assembly 2 includes an external gear 201 fixedly connected to the outer wall of the housing 11 near the feed inlet 16. A support plate 202 is fixedly connected to the bottom of one of the mounting bases near the outer wall of the housing 11. A first motor 203 is fixedly connected to the upper end of the support plate 202. A transmission shaft 204 is fixedly connected to the output end of the first motor 203. A drive gear 205 is fixedly sleeved on the outer side of the end of the transmission shaft 204 away from the first motor 203. The drive gear 205 meshes with the external gear 201. In actual use, the first motor 203 is started to drive the transmission shaft 204 to drive the drive gear 205 to rotate. The rotation of the drive gear 205 drives the external gear 201 to rotate the housing 11, thereby driving the steel balls in the roughing chamber and the finishing chamber to grind the steel slag.

[0038] As one implementation method in this embodiment, such as Figure 2 , Figure 4 and Figure 6As shown, the anti-clogging component 3 includes a placement cavity 301 opened inside the partition 12. A movable ring 302 is slidably connected to the inner side of the placement cavity 301. A mounting frame 303 is provided inside the movable ring 302. Sliding rods 304 are slidably sleeved at the four corners of the mounting frame 303. The two ends of the four sliding rods 304 are respectively fixedly connected to the inner wall of the movable ring 302. The anti-clogging component 3 also includes a bidirectional motor 305 fixedly installed inside the mounting frame 303. A rotating shaft is fixedly connected to both output ends of the bidirectional motor 305. 306. Two rotating shafts 306 are fixedly sleeved with a swing block 307 on the outer side of the end away from the bidirectional motor 305. Upper springs 308 are sleeved on the outer top of four sliding rods 304, and lower springs 309 are sleeved on the outer bottom of four sliding rods 304. The four upper springs 308 are located between the inner wall of the moving ring 302 and the upper end face of the mounting frame 303, and the four lower springs 309 are located between the inner wall of the moving ring 302 and the lower end face of the mounting frame 303. First springs 309 are fixedly connected to the outer walls of opposite sides of the moving ring 302. 10. The ends of the two first springs 310 away from the moving ring 302 are fixedly connected to the inner wall of the placement cavity 301. Hammers 311 are fixedly connected to the opposite outer walls of the mounting frame 303. In actual use, when the through groove 15 on the partition 12 is blocked, the bidirectional motor 305 is started to drive the two rotating shafts 306 to rotate the swing block 307. The swing block 307 generates centrifugal force during rotation, pushing the mounting frame 303 and its connected hammers 311 to slide on the slide rod 304. At the same time, the swing block 307 rotates... During the rotation, centrifugal force is generated, causing the moving ring 302 to slide left and right within the placement cavity 301. Due to the setting of the upper spring 308, lower spring 309 and first spring 310, the mounting frame 303 and the moving ring 302 can maintain a certain stability and buffering effect during the sliding process. As the moving ring 302 slides, the hammer head 311 begins to strike the partition 12, causing the partition 12 to vibrate. With the vibration of the partition 12, the blockage in the through groove 15 is dislodged, thereby restoring the unobstructed flow between the roughing cavity and the finishing cavity.

[0039] Working principle: Open the first cover plate 52 and the second cover plate 53, and place steel balls into the roughing chamber and the finishing chamber respectively. After placing the steel balls, close the first cover plate 52 and the second cover plate 53. Start the first motor 203 to drive the transmission shaft 204 to rotate the drive gear 205. The rotation of the drive gear 205 drives the external gear 201 to rotate the housing 11. The steel slag to be ground is added into the roughing chamber through the feed port 16. As the housing 11 rotates, the steel balls in the roughing chamber and the finishing chamber will be subjected to centrifugal force, and the steel slag will begin to be ground. The corrugated liner 40 increases the impact force and frequency of the steel balls on the steel slag in the roughing chamber, achieving rapid crushing. The initially crushed steel slag enters the finishing chamber through the through groove 15 on the partition plate 12. The flat liner 41 in the finishing chamber helps to achieve a finer grinding effect, so that the steel slag reaches the required particle size. During the grinding process, if the through groove 15 on the partition plate 12 becomes blocked... The bidirectional motor 305 is started, which drives the two rotating shafts 306 to rotate the sling block 307. During the rotation, the sling block 307 generates centrifugal force, which pushes the mounting frame 303 and its connected hammer 311 to slide on the slide rod 304. At the same time, the centrifugal force generated by the sling block 307 also causes the moving ring 302 to slide left and right in the placement cavity 301. Due to the setting of the upper spring 308, lower spring 309 and first spring 310, the mounting frame 303 and the moving ring 302 can maintain a certain stability and buffering effect during the sliding process. As the moving ring 302 slides, the hammer 311 begins to strike the partition 12, causing the partition 12 to vibrate. This vibration can effectively shake out the blockage in the through groove 15, thereby restoring the smooth flow between the roughing cavity and the finishing cavity. The ground steel slag is discharged through the discharge port 17. The spirally set discharge plate 60 helps the steel slag to smoothly enter or exit the housing 11, preventing blockage and material accumulation.
