Description

Technical Field

[0001] This utility model relates to the field of alloy silo technology, and in particular to an alloy silo for adding high-manganese iron blocks to steel ladles. Background Technology

[0002] In steelmaking, adding high-manganese iron blocks (hereinafter referred to as materials) to the ladle is an important measure to reduce alloy consumption and production costs. This operation is usually carried out using an alloy silo, with the material discharged from the silo's discharge port by its own weight. However, in actual production, it has been found that a small number of excessively large blocks inevitably mix into the high-manganese iron blocks during production and transportation. When these large blocks enter the alloy silo, they easily form bridging or blockages at the discharge port, leading to poor or even complete interruption of material flow.

[0003] In existing technologies, simple gratings are typically installed at the feed inlet of the hopper to initially remove large pieces of material. However, due to the irregular shape of the high-manganese iron blocks, large pieces can easily get stuck in the grating gaps during feeding, causing blockage of the screen itself. As the amount of stuck material increases, the screening efficiency decreases, and it may even lose its screening function, requiring shutdown for manual cleaning, which also affects the continuous and stable operation of the equipment.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Please see Figure 1-9This utility model provides an alloy hopper for adding high-manganese iron blocks to steel ladles, including a hopper body 1 and an inclined screen plate 2 fixedly installed inside the upper part of the hopper body 1. A discharge port 11 for discharging large pieces of material is opened on the upper left side of the hopper body 1, communicating with the lower side of the screen plate 2. A guide hopper 12 is fixedly connected to the outer left side wall of the hopper body 1, below the discharge port 11. The guide hopper 12 can be connected to a storage silo or a material chute. A vertically adjustable baffle 3 is connected to the discharge port 11. Material is fed onto the screen plate 2 and filtered. Qualified material falls into the hopper body 1 through the discharge chute 23, while large pieces of material slide along the inclined screen plate 2 to the discharge port 11. After screening, the baffle 3 at the discharge port 11 is raised, and large pieces of material slide down through the discharge port 11 to the guide hopper 12 for discharge.

[0021] A support frame 13 is fixedly connected to the lower end of the hopper body 1. The screen plate 2 includes multiple sets of parallel screen bars 22. Support beams 21 are fixedly connected to both ends of the lower surface of the multiple sets of screen bars 22. The support beams 21 are fixedly connected to the side wall of the hopper body 1. A material drop chute 23 is formed between two adjacent sets of screen bars 22. When welding the screen bars 22, the width of the material drop chute 23 can be determined by the size of a qualified high-manganese iron block.

[0022] Inside the hopper body 1, on the side away from the discharge port 11, a roller 4 is connected. The roller 4 is located below the screen plate 2. Multiple sets of cleaning discs 5 are fixed equidistantly along the axial direction on the outer side of the roller 4. The cleaning discs 5 are arranged in a one-to-one correspondence with the discharge chute 23. The outer edge of the cleaning disc 5 extends into the corresponding discharge chute 23. A drive assembly 6 for driving the roller 4 to slide along the length direction of the screen bar 22 is connected to the outer side of the hopper body 1. A drive assembly 7 for driving the roller 4 to rotate around its own axis is also connected to the outer side of the hopper body 1. When the drive assembly 6 drives the roller 4 to slide from the higher side to the lower side of the screen plate 2, the drive assembly 7 simultaneously drives the roller 4 to rotate clockwise.

[0023] This invention features a roller 4 that slides along the length of the screen bar 22 and a cleaning disc 5. Workers can periodically clean materials stuck in the material discharge chute 23 to restore the screen plate 2 to its optimal screening state. Specifically, when cleaning is required, the drive assembly 6 drives the roller 4 to slide from the higher side of the screen plate 2 to the lower side (e.g., ...). Figure 2 As shown, the material slides from right to left. During this process, the drive component 2 7 causes the roller 4 to rotate while translating, which in turn drives the outer cleaning disc 5 to rotate clockwise, thereby effectively prying up or pushing out the material stuck in the discharge chute 23. Under the action of gravity, the cleaned material will naturally slide along the inclined screen plate 2 surface towards the discharge port 11. This invention achieves efficient cleaning of the gaps in the screen bar 22 (discharge chute 23), significantly reducing maintenance frequency and labor intensity.

[0024] Furthermore, a cover plate 14 is fixedly connected to the upper opening of the hopper body 1, and an inlet 141 is provided through the surface of the cover plate 14 on the side away from the discharge port 11. An inlet hopper 15 is fixedly connected to the upper end of the inlet 141.

[0025] Specifically, the hopper body 1 is partially sealed by a cover plate 14. The inlet 141 is located on the surface of the cover plate 14 away from the outlet 11, allowing the input material to naturally slide down the inclined screen plate 2 from the higher side to the lower side, ensuring effective screening. Furthermore, the vertical projection of the inlet 141 onto the cover plate 14 is offset from the position of the roller 4 when it is on the higher side of the screen plate 2. This avoids the material directly hitting the roller 4 during input, reducing equipment wear, extending service life, and ensuring smooth material flow and efficient screening.

[0026] Furthermore, the upper side wall of the discharge port 11 is provided with a slot 111 for accommodating the baffle 3. A hydraulic cylinder 31 for driving the baffle 3 to rise and fall is provided on the upper left side of the hopper body 1. A fixed seat 32 is fixedly connected to the lower left side of the baffle 3. The telescopic end of the hydraulic cylinder 31 is fixed to the fixed seat 32. A base 33 is fixedly connected to the top left side of the hopper body 1. The fixed end of the hydraulic cylinder 31 is fixed to the base 33.

[0027] Specifically, when the hydraulic cylinder 31 lifts the baffle 3, the baffle 3 can retract and be hidden in the empty slot 111, which ensures that the baffle 3 will not obstruct large pieces of material from being discharged from the outlet 11 when it is in the open state.

[0028] Furthermore, a number of teeth 51 are fixedly arranged in an annular shape at equal intervals on the outer side of the cleaning disc 5.

[0029] Specifically, when the cleaning disc 5 rotates synchronously with the roller 4 under the drive of the drive assembly 7, the teeth 51 rotate accordingly, thereby prying up and ejecting the material stuck in the discharge chute 23. The teeth 51 not only enhance the gripping ability between the cleaning disc 5 and the material, but also ensure that the material can be effectively ejected through friction and compression, preventing the material from accumulating or getting stuck in the discharge chute 23.

[0030] Furthermore, the front and rear side walls of the hopper body 1 are provided with through grooves 16 that are inclined at the same degree as the screen plate 2. Both ends of the roller shaft 4 are fixedly connected with shafts 41. The two sets of shafts 41 pass through the through grooves 16 on the corresponding side and extend to the outside of the hopper body 1. The drive assembly 6 includes two sets of slides 61. The two sets of slides 61 are respectively rotatably sleeved on the outside of the shafts 41 on the corresponding side through bearings. The front and rear sides of the hopper body 1 and the bottom of the through grooves 16 are fixedly connected with slide rails 62. The slide rails 62 are arranged parallel to the through grooves 16. The slides 61 are slidably connected to the upper surface of the slide rails 62. The outside of the hopper body 1 is also connected with a drive assembly 63 for driving the two sets of slides 61 to slide synchronously along the slide rails 62.

[0031] Specifically, when it is necessary to clean the material stuck in the material drop chute 23, the two sets of slide blocks 61 are driven by the drive group 63 to slide synchronously from the higher side to the lower side along the slide rail 62. The two sets of slide blocks 61 drive the roller shaft 4 to slide through the two sets of shafts 41. Under the action of the drive component 1 6, the roller shaft 4 can slide along the length direction of the screen bar 22. Under the action of the drive component 2 7, the roller shaft 4 can rotate relative to the slide block 61, thereby indirectly driving the cleaning disc 5 to rotate.

[0032] Furthermore, the drive assembly 63 includes a first connecting shaft 631, a second connecting shaft 632, and a drive motor 636. The first connecting shaft 631 is rotatably connected to the outer left side of the hopper body 1 and located below the guide hopper 12 via two sets of lugs 18. The second connecting shaft 632 is rotatably connected to the outer right side of the hopper body 1 via two sets of lugs 18. Both ends of the first connecting shaft 631 are fixedly fitted with first sprockets 633, and both ends of the second connecting shaft 632 are fixedly fitted with second sprockets 634. The first sprockets 633 and the second sprockets 634 on the same side are fitted with a chain 635 on their outer sides. A support plate 637 for mounting the drive motor 636 is fixedly connected to the side wall of the hopper body 1. The output shaft of the drive motor 636 is fixedly connected to one end of the first connecting shaft 631. The two sets of slides 61 are respectively fixed to the chain 635 on the corresponding side via connectors 638.

[0033] Specifically, the staff starts the drive motor 636, and the output shaft of the drive motor 636 drives the first connecting shaft 631 to rotate. The first connecting shaft 631 drives the first sprockets 633 at both ends to rotate synchronously. The two sets of first sprockets 633 then drive the second sprocket 634 and the second connecting shaft 632 to rotate through their respective chains 635. At this time, the two sets of chains 635 drive the two sets of slide blocks 61 to slide along the slide rail 62 through their respective connectors 638.

[0034] Furthermore, the connector 638 includes two sets of vertically parallel clamping plates 6381. The two sets of clamping plates 6381 are respectively clamped on the upper and lower sides of the chain 635 and are fixed together by bolts 6382. The lower clamping plate 6381 is fixedly connected to the upper surface of the slide block 61.

[0035] Furthermore, the drive assembly 7 includes two sets of gears 71 and two sets of long racks 72. The two sets of gears 71 are respectively fixedly sleeved on the outside of the two sets of shafts 41. The two sets of long racks 72 are respectively fixedly connected to the front and rear side walls of the hopper body 1 through multiple sets of L-shaped brackets 73. The long racks 72 are arranged parallel to the slide rails 62 at the corresponding positions, and the two sets of long racks 72 are respectively meshed on the gears 71 on the corresponding side.

[0036] Specifically, when the chain 635 drives the slide block 61 to slide from the higher side of the screen plate 2 to the lower side, it simultaneously drives the gears 71 on the outer sides of the two sets of shafts 41 to move synchronously. Since the long rack 72 meshes above the gear 71, as the gear 71 moves from right to left, the gear 71 will rotate clockwise, thereby indirectly driving the roller 4 and the cleaning disc 5 to rotate clockwise, thus pushing the material stuck in the discharge chute 23 out from bottom to top. Secondly, there is a mechanical linkage between the second drive assembly 7 and the first drive assembly 6, both of which are driven by the drive motor 636. This ensures that as long as the roller 4 starts to slide, the roller 4 will rotate simultaneously, without the need for an additional motor, making the structure simple and reliable. In addition, the rotation direction of the roller 4 depends on its sliding direction. When the roller 4 slides from the higher side of the screen plate 2 to the lower side, the roller 4 rotates clockwise, thereby pushing out the material stuck in the discharge chute 23. When the roller 4 slides back to its original position from the lower side of the screen plate 2 to the higher side, the roller 4 rotates counterclockwise.

[0037] It should be added that, to further improve the automation level and operational safety of the equipment, limit switches (such as mechanical limit switches or photoelectric sensors) can be installed at the positions corresponding to both ends of the sliding stroke of the roller 4. When the slide 61 triggers the limit switch at either end, the signal is transmitted to the control system, which can automatically cut off the power supply to the drive motor 636, causing the roller 4 to stop at the preset limit position. The control circuit and principle of this limit protection are conventional technologies in the field and will not be described in detail here.

[0038] Furthermore, the upper end of the screen plate 2 is also provided with a cleaning plate 8 for cleaning large pieces of material. The lower end of the cleaning plate 8 is connected to the roller shaft 4. The inner front and rear side walls of the hopper body 1 are provided with sliding grooves 17 with the same inclination as the screen plate 2. The lower surface of the cleaning plate 8 is fixedly connected to both ends of a support column 81. The support column 81 passes through the corresponding material drop chute 23. The lower end of the support column 81 is fixedly connected to a fixing ring 82. The fixing ring 82 is rotatably sleeved on the outside of the roller shaft 4. The two sides of the cleaning plate 8 are fixedly connected to sliders 83 that cooperate with the corresponding sliding groove 17.

[0039] Specifically, the cleaning plate 8 can only slide along the path of the slide groove 17 under the action of the slider 83 and the slide groove 17. When the roller shaft 4 moves, it will drive the fixed ring 82, the support column 81 and the cleaning plate 8 to move synchronously. When the roller shaft 4 rotates during the movement, the cleaning plate 8 will move on the surface of the screen plate 2 like a scraper because the fixed ring 82 and the roller shaft 4 are connected by a bearing. This will efficiently push and scrape large pieces of material that are difficult to screen on the screen plate 2 to the discharge port 11, realizing automatic cleaning and discharge.

[0040] It should be noted that: 1. Flexible sealing baffles (such as rubber) can be added to both sides of the through groove 16 to effectively prevent materials from falling into the through groove 16 without affecting the free sliding of the roller 4; and protective covers can also be added to the outside of drive assembly 6 and drive assembly 7 to enhance their protection. 2. The hydraulic cylinder 31 and drive motor 636 mentioned above are electrically connected to the control terminal.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
