Description

Technical Field

[0001] This utility model relates to the field of converter smelting technology, specifically to a converter smelting feeding device. Background Technology

[0002] During steelmaking, limestone is used to replace part of the lime in slag formation. The limestone is directly fed into the converter, where it is burned into lime and then used to form slag. This process balances the excess heat in the converter, reduces the consumption of other cooling materials, and eliminates the lime calcination process, thus avoiding energy loss and pollutant emissions. This energy-saving and emission-reducing process also creates considerable economic benefits for the company. After being crushed, the limestone is usually collected in a collection box and then transferred to a conveyor belt for transport.

[0003] Patent CN220722832U discloses a limestone feeding device for converters, including a lifting platform. Columns are arranged on both sides of the lifting platform, and a tilting shaft is arranged between the columns. A material bucket is rotatably mounted on the tilting shaft, and the material bucket is driven to rotate by a rotating cylinder. A rotating block is arranged on one side of the tilting shaft, rotating together with the tilting shaft. A sensing block is arranged on the rotating block. A proximity switch is arranged on the column at a position corresponding to the lower end of the rotating block. The sensing end of the proximity switch is vertically upward. The sensing block rotates with the rotating block and contacts the sensing end of the proximity switch. The proximity switch can control the piston rod of the rotating cylinder to repeatedly extend and retract.

[0004] Currently, traditional converter smelting feeding devices are not convenient to adjust the conveyor belt angle according to the height of the converter opening at different heights. This requires manual assistance in feeding, which greatly increases the workload of the staff and affects the feeding efficiency of the fuel. In addition, the device is usually installed with bolts, which makes it inconvenient to move and reduces the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a converter smelting feeding device to solve the problems mentioned in the background art, such as the inconvenience of adjusting the conveyor belt angle according to the height of the converter opening at different heights, which leads to the need for manual feeding, greatly increasing the workload of the staff, affecting the feeding efficiency of the burning material, and the fact that the device is usually installed by bolts, making it inconvenient to move and reducing the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a converter smelting feeding device, comprising a base plate, foot supports provided around the lower end of the base plate, an installation groove provided at the lower end of the base plate, a storage mechanism fixedly connected to the inner top wall of the installation groove, an inclined mechanism fixedly connected to the upper end of the base plate, a driving component fixedly connected to one side of the upper end of the inclined mechanism, and a conveying component fixedly connected to the other side of the driving component.

[0007] The storage mechanism includes a motor, the upper end of which is detachably connected to the inner top wall of the mounting slot. The output shaft of the motor is equipped with a transmission wheel set. A bidirectional screw is provided on one side of the transmission wheel set. A transmission wheel set two is sleeved on the middle of the outer wall of the bidirectional screw. Movable blocks are threaded to both sides of the outer wall of the bidirectional screw. A diagonal rod is hinged to the lower end of the movable block. A support column is hinged to the other end of the diagonal rod. A caster wheel is fixed to the lower end of the support column. A slider is welded to the upper end of the movable block.

[0008] Preferably, the upper end of the foot support is fixedly connected to the lower end of the base plate around the perimeter, and the outer wall of the mounting groove is embedded and connected to the lower end of the base plate.

[0009] Preferably, the output shaft of the first motor is connected to one end of the first transmission wheel assembly, and the other end of the first transmission wheel assembly is sleeved on the middle of the outer wall of the bidirectional screw.

[0010] Preferably, the upper end of the support column is hinged to the inner top wall of the mounting groove.

[0011] Preferably, the tilting mechanism includes a base, the lower end of which is fixedly connected to the upper end of a base plate. A second motor is provided on the base, and a lead screw is provided on the output shaft of the second motor. A displacement block is threadedly connected to the outer wall of the lead screw. A support rod is hinged to the upper end of the displacement block, and a worktable is hinged to the upper end of the support rod. A fixed seat is rotatably connected to one side of the lower end of the worktable, and a vertical tube is fixedly connected to the other side of the lower end of the worktable. A spring is fixedly connected to the inner top wall of the vertical tube, and a damper is fixedly connected to the inner top wall of the vertical tube. A shock-absorbing block is fixedly connected to the lower end of the spring.

[0012] Preferably, one side of the base is detachably connected to one side of the second motor, and the output shaft of the second motor is connected to one side of the lead screw.

[0013] Preferably, the upper inner wall of the base is provided with a displacement groove that is adapted to the displacement block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The storage mechanism allows the equipment to flexibly adjust its movement according to different usage scenarios. When fixed operation is required, the motor is not started, the bidirectional screw remains stationary, the movable block position remains unchanged, and the support column supports the equipment through the foot brace to ensure overall stability. When the equipment needs to be moved, the motor is started to drive the transmission wheel set to rotate, which in turn drives the bidirectional screw to rotate, causing the movable blocks on both sides to move in opposite directions along the screw. The support column is pushed downward through the diagonal bar until the caster wheel contacts the ground and the foot brace is lifted. At this time, the equipment can be pushed freely, effectively solving the problem of difficult movement caused by bolt fixing in traditional devices. This significantly improves the practicality and adaptability of the equipment. At the same time, the mechanism adopts a mechanical transmission structure, which has a lower failure rate and maintenance cost compared to the hydraulic system. The thread self-locking characteristic of the bidirectional screw and the movable block can ensure the positioning accuracy of the caster wheel in the extended or retracted state, avoiding accidental displacement during operation.

[0016] 2. The tilting mechanism allows the equipment to precisely adjust the conveyor belt angle according to the needs of different converter opening heights. When the tilt of the worktable needs to be adjusted, the motor drives the lead screw to rotate, which in turn moves the displacement block horizontally along the displacement groove. The hinged structure of the support rod pushes the worktable to rotate around the fixed seat, thereby adjusting the pitch angle of the conveying component. During this process, the spring and damper inside the vertical tube form a composite shock absorption effect. When the angle of the worktable changes and the vertical tube is compressed, the spring provides elastic buffering force, and the damper consumes vibration energy through hydraulic damping effect. Through synergistic action, the impact load generated during equipment adjustment can be effectively suppressed. Furthermore, the composite structure of lead screw drive and hinged connecting rod has higher transmission efficiency and angle control accuracy compared to traditional hydraulic adjustment systems. The displacement groove limits the stroke of the displacement block, which can precisely control the maximum tilt angle of the worktable and prevent material slippage or equipment overload caused by excessive adjustment.

The overall design of the storage mechanism 4, with its well-coordinated components, ensures rapid and precise movement of the conveying component 7.

[0027] Please see Figure 3In order to quickly adjust the angle of the conveying component 7 on the workbench 56, the tilting mechanism 5 includes a base 51. The lower end of the base 51 is fixedly connected to the upper end of the base plate 1. The base 51 is equipped with a second motor 52. The output shaft of the second motor 52 is equipped with a lead screw 53. The outer wall of the lead screw 53 is threadedly connected to a displacement block 54. The upper end of the displacement block 54 is hinged to a support rod 55. The upper end of the support rod 55 is hinged to the workbench 56. The lower end of the workbench 56 is rotatably connected to a fixed seat 57. The other lower end of the workbench 56 is fixedly connected to a vertical tube 58. The inner top wall of the vertical tube 58 is fixedly connected to a spring 59. The inner top wall of the vertical tube 58 is fixedly connected to a damper 510. The lower end of the spring 59 is fixedly connected to a shock absorber 511. One side of the base 51 is detachably connected to one side of the second motor 52. The output shaft of the second motor 52 is drivenly connected to one side of the lead screw 53. The upper inner wall of the base 51 is provided with a displacement groove that matches the displacement block 54.

[0028] To enable rapid and efficient angle adjustment of the conveying assembly 7 on the worktable 56, the lower end of the base 51 and the upper end of the base plate 1 are securely connected together to ensure the stability of the overall structure. A second motor 52 is installed on one side of the base 51, serving as the power source. A lead screw 53 is mounted on its output shaft. The outer wall of the lead screw 53 is threaded to a displacement block 54, allowing the displacement block 54 to move up and down under the rotation of the lead screw 53. A support rod 55 is hinged to the upper end of the displacement block 54, and the other end of the support rod 55 is hinged to the worktable 56, forming an adjustable support structure. One side of the lower end of the worktable 56 is connected to a fixed base 57 via a rotatable connection, allowing the worktable 56 to rotate within a certain range. A vertical pipe 58 is fixed to the other side of the lower end of the worktable 56, with a vertical pipe 58 fixed to its inner top wall. The mechanism includes a spring 59 and a damper 510. These two components work together to provide necessary support and also to buffer and absorb shocks. The lower end of the spring 59 is fixed to a shock-absorbing block 511, which further enhances the shock absorption performance of the entire mechanism. For easy maintenance and replacement, one side of the base 51 is detachably connected to one side of the motor 52, allowing for more flexible adjustment and replacement during operation. The output shaft of the motor 52 is connected to one side of the lead screw 53 via a transmission connection, ensuring that the power of the motor 52 can be effectively transmitted to the lead screw 53. In addition, the upper inner wall of the base 51 has a displacement groove that matches the displacement block 54. This design ensures that the displacement block 54 remains stable during movement, preventing deviation or jamming. Through this structural design, the tilting mechanism 5 can quickly and accurately adjust the angle of the worktable 56, greatly improving work efficiency and ease of operation.

[0029] Working principle: First, the motor 41 in the storage mechanism 4 is started. The motor 41 drives the transmission wheel set 42 to rotate, which in turn drives the double-sided screw 43 to rotate. The rotation of the double-sided screw 43 causes the movable blocks 45 on both sides to move towards or away from each other along the screw 43 under the action of the threads. The movement of the movable blocks 45 drives the inclined rod 46 to move, which pushes the support column 47 downward. The support column 47 drives the caster wheel 48 to extend downward, allowing the entire device to move flexibly through the caster wheel 48. When it reaches the appropriate position, the motor 41 is started in reverse, causing the caster wheel 48 to retract into the mounting slot 3. At this time, the foot support 2 supports the entire device, ensuring the stability of the device during operation. When different heights are needed... When adjusting the angle of the conveying component 7 at the converter furnace opening, the second motor 52 in the tilting mechanism 5 is started. The operation of the second motor 52 drives the lead screw 53 to rotate. The rotation of the lead screw 53 causes the displacement block 54 to move in the displacement groove. The movement of the displacement block 54 drives the support rod 55 to move. The support rod 55 pushes the worktable 56 to rotate around the fixed seat 57, thereby realizing the adjustment of the angle of the conveying component 7 on the worktable 56. During the rotation of the worktable 56, the spring 59 and the damper 510 in the vertical tube 58 work together to buffer and reduce the shock of the worktable 56, ensuring the stability of the worktable 56 during the adjustment process. When the angle is adjusted to be appropriate, the operation of the second motor 52 is stopped. At this time, the conveying component 7 is at the appropriate angle and can carry out normal converter smelting feeding work.

[0030] Then, the conveying component 7 is started by the drive component 6. The drive component 6 provides continuous and stable power to the conveying component 7, ensuring that the material can be conveyed at a predetermined speed and direction. The conveying component 7 starts to operate under the action of the drive component 6, and smoothly conveys the material to the converter mouth. During the entire feeding process, the device is equipped with a storage mechanism 4 and a tilting mechanism 5, which allows the device to move flexibly and adjust its angle according to actual needs, greatly improving the efficiency and convenience of feeding. At the same time, the cooperation of the foot support 2 and the universal wheel 48 also ensures the stability and safety of the device during movement and operation. After the feeding work is completed, the storage mechanism 4 can be started again to retract the universal wheel 48 into the mounting slot 3, so that the device returns to its initial state, which is convenient for subsequent use and storage. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
