Description

Technical Field

[0001] This utility model belongs to the field of lime proportioning control technology, and specifically relates to a quicklime proportioning control device. Background Technology

[0002] In the steelmaking process, the production of high vanadium-titanium sinter has strict requirements on the raw material ratio, especially the ratio of quicklime, which has a significant impact on the physical and metallurgical properties of the sinter.

[0003] Currently, Chinese utility model patent CN220182170U discloses a quicklime feeding pipe device for sintering batching, which relates to the field of ore sintering production technology. This device, through a variable diameter pipe, cannot solve the problem of material blockage because the main component of quicklime is CaO, which is usually a blocky solid. Due to the lack of a structure for crushing materials, the pipe is prone to blockage. At the same time, it cannot automatically control the lime ratio, which easily leads to problems such as low ratio accuracy, low efficiency, and easy errors, making it difficult to meet the requirements of modern steel production for high quality, high efficiency, and low cost. Utility Model Content

[0004] The purpose of this invention is to provide a quicklime proportioning control device, which has the advantage of being able to automatically control the amount of quicklime added while crushing lumpy quicklime.

[0006] The above technical solution involves: starting a stepper motor to drive the driven wheel to rotate, which in turn drives the connecting shaft to rotate the first and second crushing rollers. The quicklime is squeezed into small pieces by the interlocking of the crushed blocks, preventing blockage of the discharge pipe. Starting a drive motor to drive a bidirectional screw to rotate allows the two connecting blocks to move closer or separate, thus allowing the two baffles to rotate into a conical or flat shape. The lime ratio is controlled according to the angle of the conical baffles, achieving precise control of the ratio, improving the quality of sintered ore, reducing manual intervention, shortening the production cycle, and improving production efficiency.

[0007] The present invention is further configured such that the bottom of the material hopper is conical.

[0008] The above technical solution facilitates the normal feeding of materials.

[0009] The present invention is further configured such that the number of supporting legs is four, and the inner wall of the supporting legs is provided with mounting holes.

[0010] The above technical solution facilitates fixing the material hopper onto the conveyor.

[0011] The present invention is further configured such that the driving mechanism includes a housing fixed to one side of the material hopper, and a stepper motor is fixedly connected to one side of the housing.

[0012] The above technical solution facilitates the rotation of both the driving wheel and the driven wheel.

[0013] The present invention is further configured such that the driving mechanism includes a driving wheel fixed to the output end of the stepper motor, and a driven wheel is meshed with the outer side of the driving wheel, and both the driving wheel and the driven wheel are located inside the housing.

[0014] The above technical solution facilitates gear protection.

[0015] The present invention is further configured such that the inner rings of the driving wheel and the driven wheel are fixedly connected to a connecting shaft, and one end of the connecting shaft passes through one side of the material hopper and is fixedly connected to the first crushing roller and the second crushing roller respectively.

[0016] The above technical solution facilitates the rotation of the first and second crushing rollers.

[0017] The present invention is further configured such that the crushed blocks on the first crushing roller and the crushed blocks on the second crushing roller are staggered.

[0018] The above technical solution facilitates the crushing of materials.

[0019] The present invention is further configured such that threaded holes are provided on the inner walls of both the connecting block and the mounting base, and bolts are fixedly connected to the inner walls of the threaded holes.

[0020] The above technical solution facilitates the assembly and disassembly of the connecting block and the mounting base.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. Start the stepper motor to make the drive wheel drive the driven wheel to rotate, which in turn makes the connecting shaft drive the first crushing roller and the second crushing roller to rotate. The quicklime is squeezed into small pieces by the interlocking of the crushed pieces, avoiding blockage of the discharge pipe.

[0023] 2: Start the drive motor to drive the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it can bring the two connecting blocks closer or separate, thereby allowing the two baffles to rotate into a pointed cone or flat plate shape. The lime ratio is controlled according to the angle of the pointed cone baffle, which realizes precise control of the ratio, improves the quality of sintered ore, reduces manual intervention, shortens the production cycle, and improves production efficiency.

[0032] refer to Figure 1 and Figure 2 The bottom of material hopper 1 is cone-shaped.

[0033] refer to Figure 1 and Figure 2 There are four support legs 2, and the inner wall of the support legs 2 has mounting holes.

[0034] The number of mounting holes on each support leg 2 is four, which facilitates the installation of the material hopper 1 on the conveyor.

[0035] refer to Figure 1 , Figure 2 and Figure 3 The drive mechanism includes a housing 7 fixed to one side of the material hopper 1, and a stepper motor 8 is fixedly connected to one side of the housing 7.

[0036] refer to Figure 1 , Figure 2 and Figure 3 The drive mechanism also includes a drive wheel 9 fixed to the output end of the stepper motor 8. A driven wheel 10 is meshed with the outer side of the drive wheel 9. Both the drive wheel 9 and the driven wheel 10 are located inside the housing 7. A support rod is fixedly connected to the bottom of the driven wheel 10. The support rod is rotatably connected to the inner wall of the housing through a bearing seat.

[0037] refer to Figure 2 and Figure 3 The inner rings of the driving wheel 9 and the driven wheel 10 are both fixedly connected to a connecting shaft 11. One end of the connecting shaft 11 passes through one side of the material hopper 1 and is fixedly connected to the first crushing roller 4 and the second crushing roller 5 respectively.

[0038] refer to Figure 3 The crushed blocks 6 on the first crushing roller 4 and the crushed blocks 6 on the second crushing roller 5 are staggered.

[0039] Brief description of the process: After being weighed by the batching scale, quicklime enters the hopper 1 and falls between the first crushing roller 4 and the second crushing roller 5. At this time, the stepper motor 8 is started to drive the driven wheel 10 to rotate. When the driven wheel 9 and the driven wheel 10 rotate, the connecting shaft 11 drives the first crushing roller 4 and the second crushing roller 5 to rotate. The quicklime is squeezed into small pieces by the interlocking of the crushed blocks 6, thus avoiding blockage of the discharge pipe 3.

[0040] Example 2:

[0041] refer to Figure 1 , Figure 2 and Figure 4 A quicklime proportioning control device includes a material hopper 1. A bidirectional lead screw 12 is rotatably connected to the inner wall of the material hopper 1 via a bearing. A connecting block 13 is threadedly connected to the outer side of the bidirectional lead screw 12. There are two connecting blocks 13. A mounting base 14 is provided on the top of the connecting block 13. A mounting block 15 is fixedly connected to the top of the mounting base 14. A baffle 16 is rotatably connected to the mounting block 15. A drive motor 17 is fixedly connected to one side of the material hopper 1 via a support plate.

[0042] refer to Figure 4 Both the connecting block 13 and the mounting base 14 have threaded holes 18 on their inner walls, and bolts 19 are fixedly connected to the inner walls of the threaded holes 18.

[0043] The use of bolt 19 and threaded hole 18 facilitates the separation of mounting base 14 from connecting block 13, thereby allowing baffle 16 to be disassembled.

[0044] Brief description of the usage process: Start the drive motor 17 to drive the bidirectional lead screw 12 to rotate. When the bidirectional lead screw 12 rotates, it can bring the two connecting blocks 13 closer together or separate, so that the two baffles 16 can rotate through the mounting block 15 into a pointed cone shape or a flat plate shape. The closer the two baffles 16 are, the faster and more the material is fed. Conversely, the feeding speed is slower and less. The lime ratio is controlled according to the angle of the pointed cone baffle 16, and the flat plate baffle 16 can block the material.
