Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, specifically to a valve plate adjustment and control device for a metallurgical feeding device. Background Technology

[0002] Metallurgical machinery is a concept in the mechanical industry, mainly including machinery for smelting steel and iron. In the metallurgical process, materials are discharged from silos onto the conveying mechanism of the feeding device, which then transports the materials to subsequent smelting units for further processing.

[0003] Existing silo discharge ports are typically equipped with valve plates to control the discharge rate. Most existing valve plates are vertically inserted, with the discharge port size adjusted by lifting the valve plate up or down. In practical use, due to limitations imposed by site conditions, lifting the valve plate up or down is inconvenient and can easily lead to mechanical injuries. Furthermore, the vertical angle of the discharge port on the vertically positioned valve plate results in poor material flowability, uneven material flow rate, and a tendency for imbalances in the batching ratio. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a valve plate adjustment and control device for metallurgical feeding devices. It facilitates the adjustment of the valve plate angle, precisely controls the material flow rate to ensure uniform material flow, and is safe and easy to operate.

[0005] This utility model is achieved through the following technical solution: a valve plate adjustment and control device for a metallurgical feeding device, comprising a hopper and a valve plate. The hopper has an opening at the bottom and a conveying mechanism at the bottom. A discharge port is provided on the side wall of the hopper. The valve plate is located at the discharge port of the hopper. The upper end of the valve plate is hinged to the hopper via a first hinge shaft, which is horizontally positioned. A support frame is fixedly connected to the side wall of the hopper. The support frame is located above the valve plate, and a driving mechanism is hingedly installed on the support frame. The driving mechanism drives the valve plate to rotate around the first hinge shaft.

[0006] This design incorporates a rotating valve plate, driven by a mechanism to create a specific flow angle between the valve plate and the conveying mechanism. This results in smoother material discharge from the outlet, facilitating even material distribution and precise flow control. Furthermore, the rotating valve plate design makes angle adjustment easier and operation safer.

[0007] As an optimization, baffles are provided at both axial ends of the valve plate. The baffles extend along the conveying direction of the conveying mechanism, are fixedly connected to the side wall of the hopper, and have their bottoms flush with the bottom of the hopper. This optimization solution prevents material from leaking out through the gaps on both sides of the valve plate by blocking the gaps with the baffles.

[0008] As an optimization, the drive mechanism includes a fixed base, a threaded sleeve, a threaded rod, a bearing, and a transmission rod. The fixed base is hinged to the support frame via a second hinge shaft, which is parallel to the first hinge shaft. The threaded sleeve is fixed to the fixed base, and the threaded rod is threadedly connected to the threaded sleeve. The axial direction of the threaded rod is perpendicular to the second hinge shaft. One end of the transmission rod is hinged to the valve plate via a third hinge shaft, which is parallel to the first hinge shaft. The other end of the transmission rod is rotatably connected to one end of the threaded rod via the bearing, and a handle is fixed to the other end of the threaded rod. This optimized solution, by hinged between the fixed base and the support frame, allows the entire drive mechanism to adjust its angle accordingly with the rotation of the valve plate. The lifting action is achieved through the cooperation of the threaded rod and the threaded sleeve, thereby pulling the transmission rod and driving the rotation of the valve plate. During operation, the operator only needs to rotate the threaded rod outside the hopper to adjust the valve plate angle, making it safe and convenient to use.

[0009] As an optimization, the transmission rod, threaded rod, and bearing are coaxially arranged. The threaded rod is fixed to the inner wall of the bearing via a first connecting rod, and the transmission rod is fixed to the outer wall of the bearing via a second connecting rod. In this optimized scheme, the threaded rod is connected to the inner wall of the bearing, and the transmission rod is connected to the outer wall of the bearing, enabling the independent rotation of the threaded rod.

[0010] As an optimization, the valve plate has an arc-shaped structure, with its lower end extending away from the discharge port. This optimized arc-shaped valve plate allows for a natural transition in material flow, improving the guiding effect and ensuring smoother material discharge.

[0011] As an optimization, a vibrator is fixed to the side wall of the silo. This optimization scheme prevents material from accumulating inside the silo through the vibration of the vibrator.

[0012] As an optimization, an air cannon is installed on the side wall of the silo, and the exhaust pipe of the air cannon is connected to the inner cavity of the silo. This optimized solution uses the air cannon to increase the high-pressure airflow into the silo, preventing material from sticking to the wall and allowing the material to be discharged smoothly.

[0013] The beneficial effects of this utility model are as follows: The valve plate is designed as a rotating type, driven by a drive mechanism to rotate, forming a certain flow angle between the valve plate and the conveying mechanism. This results in smoother material discharge from the outlet, facilitating uniform material discharge and precise control of material flow. Furthermore, the rotating valve plate design makes adjusting the valve plate angle more convenient and safer to operate.

[0014] The valve plate adopts an arc-shaped structure design, which allows materials to flow naturally and transition smoothly, improving the guiding effect on materials and making material discharge smoother.

[0015] The drive mechanism is hinged to the support frame via a fixed base, allowing the entire drive mechanism to adjust its angle in accordance with the rotation of the valve plate. The lifting action is achieved through the cooperation of a threaded rod and a threaded sleeve, which in turn moves the transmission rod, thereby driving the rotation of the valve plate. During operation, the operator only needs to rotate the threaded rod from the outside of the hopper to adjust the valve plate angle, making it safe and convenient to use. Attached Figure Description

Detailed Implementation

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] like Figures 1-4 As shown, a valve plate regulating and control device for a metallurgical feeding apparatus includes a hopper 1 and a valve plate 4. The hopper 1 has an opening at the bottom and a conveying mechanism 3 at the bottom. A discharge port 2 is provided on the side wall of the hopper 1. The conveying mechanism 3 is a conveyor, and the discharge port 2 is located at the bottom of the side wall of the hopper 1. The material in the hopper 1 falls onto the conveyor, and through the conveyor, the material is output to the outside from the discharge port 2.

[0024] The valve plate 4 is disposed at the discharge port 2 of the hopper 1. The upper end of the valve plate 4 is hinged to the hopper 1 via a first hinge shaft 6, which is horizontally positioned. In this embodiment, the valve plate 4 has an arc-shaped structure, with its lower end extending away from the discharge port 2. The arc-shaped valve plate 4 allows for a natural flow transition of the material, improving the guiding effect on the material and making the material discharge smoother.

[0025] The axial length of the valve plate 4 is greater than the length of the discharge port 2, allowing the valve plate 4 to completely block the material in the axial direction. Since the valve plate 4 is arc-shaped, to prevent material from being discharged from the gaps on both sides of the valve plate 4 during discharge from the discharge port 2, baffles 12 are provided at both ends of the valve plate 4 in this embodiment. The baffles 12 extend along the conveying direction of the conveying mechanism 3, are fixedly connected to the side wall of the hopper 1, and have their bottom flush with the bottom of the hopper 1. The height of the baffles 12 is higher than the height of the discharge port 2, forming a material channel between the two baffles 12 and the bottom of the valve plate 4. By blocking the gaps on both sides of the valve plate 4 with the two baffles 12, the material can only be output from the material channel, preventing leakage from the gaps on both sides.

[0026] A support frame 5 is fixedly connected to the side wall of the silo 1. The support frame 5 is located above the valve plate 4. A drive mechanism 9 is hingedly installed on the support frame 5. The drive mechanism 9 drives the valve plate 4 to rotate around the first hinge axis 6.

[0027] Specifically, the drive mechanism 9 includes a fixed base 91, a threaded sleeve 92, a threaded rod 93, a bearing 95, and a transmission rod 94. The fixed base 91 is hinged to the support frame 5 via a second hinge shaft 7. The threaded sleeve 92 is fixedly connected to the fixed base 91, and the threaded rod 93 is threadedly connected to the threaded sleeve 92, with the axial direction of the threaded rod 93 perpendicular to the second hinge shaft 7. One end of the transmission rod 94 is hinged to the valve plate 4 via a third hinge shaft 8, and the third hinge shaft 8 and the transmission rod 94 are fixedly connected to form a T-shaped structure. The first hinge shaft 6, the second hinge shaft 7, and the third hinge shaft 8 are parallel to each other and arranged in a triangle. The other end of the transmission rod 94 is rotatably connected to one end of the threaded rod 93 via the bearing 95, and a handle 96 is fixedly connected to the other end of the threaded rod 93.

[0028] The support frame 5 described in this embodiment includes two parallel support rods, which are horizontally arranged. One end of each support rod is fixed to the outer wall of the hopper 1, and the other end extends away from the hopper 1, with the support rod perpendicular to the first hinge shaft 6. The fixed base 91 is a rectangular block, with the second hinge shaft 7 fixed to both sides of the rectangular block. The rectangular block is hinged to the end of the support rod away from the hopper 1 via the second hinge shaft 7. The threaded sleeve 92 passes through the center of the rectangular block and is fixed thereto.

[0029] The transmission rod 94, threaded rod 93, and bearing 95 are coaxially arranged. The threaded rod 93 is fixedly connected to the inner wall of the bearing 95 via a first connecting rod 97, and the transmission rod 94 is fixedly connected to the outer wall of the bearing 95 via a second connecting rod 98. The connection between the threaded rod 93 and the inner wall of the bearing 95, and the connection between the transmission rod 94 and the outer wall of the bearing 95, enables the independent rotation of the threaded rod 93.

[0030] The drive mechanism 9 is hinged to the support frame 5 via a fixed base 91, allowing the entire drive mechanism 9 to adjust its angle accordingly as the valve plate 4 rotates. The lifting action is achieved through the cooperation of the threaded rod 93 and the threaded sleeve 92, which in turn pulls the transmission rod 94, thereby driving the valve plate 4 to rotate. During operation, the operator only needs to rotate the threaded rod 93 on the outside of the hopper 1 to adjust the angle of the valve plate 4, making it safe and convenient to use.

[0031] A vibrator 10 is fixed to the side wall of the silo 1. The vibrator 10 is a silo wall vibrator 10, which can be directly purchased from the market. The vibration of the vibrator 10 prevents material from accumulating in the silo 1. An air cannon 11 is also provided on the side wall of the silo 1, and the exhaust pipe of the air cannon 11 is connected to the inner cavity of the silo 1. In this embodiment, the air cannon 11 is the air cannon 11 of patent CN201198397Y. The air cannon 11 provides high-pressure airflow into the silo 1 to prevent material from sticking to the wall and to allow the material to be discharged smoothly.

[0032] In this embodiment, a flow sensor (not shown in the figure) is also installed in the silo 1 to monitor the material flow rate inside the silo 1, thereby determining whether there is a blockage. The flow sensor is electrically connected to a control processor, and the vibrating motor and air cannon 11 are also electrically connected to the control processor. The material flow data of the vibrator 10, the air cannon 11, and the control processor are interlocked to achieve automatic control. For example, when the flow sensor detects that the material velocity fluctuation is greater than 5% of the set value, the control processor can send a signal to the vibrator 10 and the air cannon 11 to make the vibrator 10 vibrate and the air cannon 11 emit jets of air to clear the blockage and reduce the blockage in the silo 1.

[0033] Working principle: When the valve plate 4 is adjusted, the threaded rod 93 is rotated by the handle 96, so that the threaded rod 93 moves along the threaded sleeve 92, thereby driving the transmission rod 94 to move, and then driving the valve plate 4 to adjust the angle.
