Description

Technical Field

[0001] This utility model belongs to the field of sintered ore processing, and in particular relates to a crushing device for large-particle sintered ore. Background Technology

[0002] Sintered ore is an indispensable raw material in modern blast furnace ironmaking. It is a process of preparing artificial lump ore by mixing various iron-containing powdered ores that cannot be directly used in blast furnaces, such as concentrate powder, rich ore powder, and iron-containing dust recovered during steel production, with a certain proportion of fuel and flux. After uniform mixing, the mixture is sintered at high temperature in a sintering machine. On the sintering machine, the mixture is ignited and burned. The high temperature generated by the combustion of fuel causes the material to melt locally, resulting in a series of complex physicochemical reactions. Finally, it solidifies into a porous blocky material with a certain strength and alkalinity, which is sintered ore. However, when mixing in fuel and flux, the sintered ore needs to be crushed first. In the traditional process, large particles of sintered ore are manually crushed, which easily leads to incomplete crushing. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, a crushing device for large-particle sintered ore includes a feeding unit 1, a crushing unit 2, a driving unit 3, and a support 4. The support 4 is positioned above the conveyor line, and the crushing unit 2 and driving unit 3 are fixedly mounted on the support 4. The discharge end of the crushing unit 2 faces the conveyor line, and the feeding end of the crushing unit 2 is fixedly mounted with the feeding unit 1. The feeding unit 1 is used to guide the sintered ore into the crushing unit 2, which is used to crush the sintered ore. The driving unit 3 is used to drive the crushing unit 2. The crushing unit 2 includes a housing 21, a shaft 22, a bearing seat 23, and a rotating wheel 24. The support... 4. A housing 21 is fixedly installed on the upper part. A bearing seat 23 is installed on each side of the housing 21. The shaft 22 passes through the housing 21 and is rotatably connected in the bearing seat 23. The rotating wheel 24 is fixedly installed at one end of the shaft 22. The other end of the shaft 22 is connected to the drive unit 3. The housing 21 is provided with a shaft plate 25, a connecting rod 26 and a breaker hammer 27. Multiple shaft plates 25 are fixedly sleeved around the shaft 22. The multiple shaft plates 25 are arranged parallel to each other. Multiple connecting rods 26 are arranged circumferentially between every two adjacent shaft plates 25. A breaker hammer 27 is rotatably arranged around the periphery of each connecting rod 26. During operation, the controller is turned on, and the controller drives the shaft 22 to rotate stably within the bearing seats 23 on both sides of the housing 21. When the shaft 22 rotates, multiple parallel shaft pieces 25 fixedly sleeved around it rotate synchronously, thereby driving the connecting rods 26 circumferentially distributed between adjacent shaft pieces 25 to make circular motion with the shaft 22. Since the breaker hammer 27 is rotatably set around the connecting rod 26, the breaker hammer 27 will swing outward under the action of centrifugal force, performing high-frequency impact and crushing on large particles of sintered ore entering the housing 21 from the upper feeding unit 1. The crushed sintered ore falls onto the conveyor belt. The cooperation between the connecting rod 26 and the rotatable breaker hammer 27 gives the breaker hammer 27 a flexible impact angle and strong impact force under the action of centrifugal force. It can quickly crush large particles of sintered ore and avoid material jamming in the housing 21, thus solving the problem that manual crushing of large particles of sintered ore in the traditional process easily leads to incomplete crushing and insufficient refining.

[0023] like Figure 4 As shown, the outer side of the housing 21 is provided with an inspection port 211, and the outer side of the inspection port 211 is detachable with a mounting cover 212. When the sinter is stuck, the cover 212 can be opened and the rotating wheel 24 can be rotated to remove the stuck sinter from the inspection port 211. The parts inside the housing 21 can also be further inspected or replaced.

[0024] like Figure 4 and Figure 5 As shown, the lower end of the shell 21 is provided with a discharge port 213, which faces the conveyor line. A screen plate 214 is fixedly installed inside the shell 21 near the discharge port 213. The screen plate 214 is provided with multiple screen holes 2141. The screen plate 214 with screen holes 2141 can control the diameter of the discharged sinter, ensuring that the diameter of the crushed sinter is qualified and can be fully refined.

[0025] like Figure 6 As shown, the feeding unit 1 includes a funnel 11, an inclined plate 12, and multiple baffles 13. The upper end of the crushing unit 2 is connected to the outlet of the funnel 11. The inclined plate 12 is fixedly installed inside the funnel 11. Multiple baffles 13 are hinged to one side of the inclined plate 12. The multiple baffles 13 are arranged parallel to each other. When large particles of sinter are put into the funnel 11, the sinter will slide down along the side wall of the inclined plate 12 and the funnel 11 into the shell 21. When sliding in, the baffles 13 fold inward. After feeding is completed, the baffles 13 fall naturally under the action of gravity to close the passage. The feeding unit 1 can slide large particles of sinter into the shell 21. The single baffles 13 can also prevent dust from overflowing during the crushing process and reduce air pollution.

[0026] like Figure 7 and Figure 8 As shown, the drive unit 3 includes a servo motor 31, a synchronous pulley 32, and a synchronous belt 33. The servo motor 31 is fixedly installed on the upper end of the bracket 4, and the synchronous pulley 32 is fixedly installed on one end of the shaft 22. The output shaft of the servo motor 31 and the synchronous pulley 32 are synchronously transmitted through a synchronous belt 33. The servo motor 31 is existing technology, and its model is ACM1S-08008H2E1-M17S MS30. When the controller is turned on, the controller controls the servo motor 31 to rotate. The output shaft of the servo motor 31 drives the synchronous pulley 32 and the synchronous belt 33 to rotate, and further drives the shaft 22 to rotate. A dust cover 34 is provided on one side of the servo motor 31. The dust cover 34 covers the output shaft of the servo motor 31, the synchronous pulley 32, and the synchronous belt 33. The dust cover 34 can block dust in nature and dust generated during the crushing of sintered ore, thus extending the overall service life of the device.

[0027] The working process of a crushing device for large-particle sintered ore: First, large-particle sinter is fed into the hopper 11 of the feeding unit 1. The inclined plate 12 inside the hopper 11 guides the material to slide downwards. The sinter passes through the baffle 13 and enters the shell 21 of the crushing unit 2. At this time, the servo motor 31 of the drive unit 3 starts, and its output shaft forms a synchronous transmission with the synchronous pulley 32 at one end of the shaft 22 through the synchronous belt 33 sleeved on the outside. This drives the shaft 22 to rotate stably in the bearing seats 23 on both sides of the shell 21. When the shaft 22 rotates, the multiple parallel shaft pieces 25 fixedly sleeved on its outside rotate synchronously, driving the multiple connecting rods 26 circumferentially arranged between adjacent shaft pieces 25 to perform circular motion with the shaft 22. The breaker hammer 27, which is rotatably mounted on the outer periphery of the connecting rod 26, swings outward under the action of centrifugal force, and performs high-frequency impact crushing on large particles of sintered ore inside the shell. The crushed material falls onto the screen plate 214 inside the shell 21 near the discharge port 213. Qualified material that meets the aperture of the screen hole 2141 falls into the conveyor line below from the discharge port 213 through the screen hole 2141. Large particles that do not meet the standard remain on the screen plate 214 and are further crushed by the breaker hammer 27. If maintenance is required, the cover plate 212 of the inspection port 211 on the outside of the shell 21 can be removed, and the internal components can be inspected or replaced by rotating the shaft 22 with the wheel 24.

[0028] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
