Description

Technical Field

[0001] The utility model relates to the technical field of ferroalloy submerged arc furnaces, in particular to a carbon rod holder structure for the tuyere of a ferroalloy submerged arc furnace. Background Art

[0002] In the existing tuyere opening operation, the carbon rod method is often used. However, the carbon rod holder itself is heavy, and the operation requires the cooperation of more than two people, with a relatively high operation difficulty. The burner carbon block is prone to wear and form irregular pits, and the contact between the steel rod of the carbon rod holder and the burner carbon block is poor, which is prone to arcing. The steel rod of the carbon rod holder and the steel structure are prone to burning and deformation, resulting in a large amount of material waste. Therefore, a carbon rod holder structure for the tuyere of a ferroalloy submerged arc furnace is used to hoist the carbon rod.

[0003] The prior art such as the utility model with the publication number CN213273779U discloses a carbon rod holder structure for the tuyere of a ferroalloy submerged arc furnace. This patent adopts an annular guide rail on the upper part of the submerged arc furnace body. A hanging device is installed on the guide rail, and the bottom end of the hanging device is connected with a carbon rod clamp. A carbon rod is installed inside the carbon rod clamp. The other end of the carbon rod clamp is provided with a connecting rod, and a water jacket for cooling is sleeved on the connecting rod. The end of the connecting rod far from the carbon rod clamp is provided with a straight rod-shaped carbon rod holder. The equipment of the utility model solves the problems that the existing equipment is prone to electric shock injury to personnel due to improper operation. Therefore, if not improved, it will not only increase the production cost, but also have a low safety factor and many potential hazards. Once an accident occurs, it will cause huge losses to our factory.

[0004] In daily work, during the process of the equipment adjusting the angle of the carbon rod, there is a problem that it is difficult to rotate and adjust the carbon rod, and it is difficult to quickly adjust the carbon rod when inserting it into the furnace body at different angles. Summary of the Invention

[0005] The purpose of the utility model is to solve the shortcoming that it is difficult to quickly adjust the carbon rod in the prior art, and a carbon rod holder structure for the tuyere of a ferroalloy submerged arc furnace is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A carbon rod holder structure for the tuyere of a ferroalloy submerged arc furnace, including a furnace body, a hanging bracket, a carbon rod, a first connecting bracket, a second connecting bracket and a rotating device. A hanging bracket is arranged above the furnace body. The second connecting bracket is slidably connected below the hanging bracket. The first connecting bracket is arranged on the lower surface of the second connecting bracket. The rotating device is arranged on the upper surface of the hanging bracket. The rotating device includes a connecting arm and a connecting rod. The connecting arm is fixedly connected to the upper surface of the second connecting bracket. The connecting rod is fixedly connected to the side surface of the connecting arm. A rotating rod is fixedly connected to the upper surface of the hanging bracket. A rotating block is sleeved and connected to the surface of the rotating rod. A first gear is fixedly connected to the upper surface of the rotating block. The connecting rod is fixedly connected to the side surface of the rotating block.

[0007] Further, a limiting block is fixedly connected to the upper surface of the rotating rod. The limiting block is arranged on the surface of the first gear. By providing the limiting block, the rotating block can be limited, reducing the situation that the rotating block is likely to break away from the hanging bracket during the use of the equipment, resulting in the difficulty of the equipment to rotate and adjust the connecting rod.

[0008] Further, a limiting frame is fixedly connected to the upper surface of the limiting block, and a motor is fixedly connected to the side surface of the limiting frame. The motor is provided to facilitate the rotation of the second gear.

[0009] Further, the output end of the motor is fixedly connected to a second gear, and the second gear is meshed with the first gear. The second gear is provided to facilitate the meshing rotation of the first gear.

[0010] Further, an adjusting device is arranged on the surface of the first connecting frame. The adjusting device includes a sliding column and a connecting column. The sliding column is slidably connected to the inside of the first connecting frame, and the connecting column is fixedly connected to one end of the sliding column. By providing the sliding column, the carbon rod can be limited and moved, reducing the situation that the carbon rod is difficult to be limited and moved during the use of the equipment.

[0011] Further, a positioning block is fixedly connected to the surface of the sliding column, and a first cylinder is fixedly connected to the side surface of the positioning block. The positioning block is provided to facilitate the limitation of the sliding column.

[0012] Further, a second cylinder is fixedly connected to the side surface of the second connecting frame, and one end of the second cylinder is fixedly connected to the surface of the first connecting frame. The second cylinder is provided to facilitate the movement of the first connecting frame.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] In the present utility model, when the equipment is in use, the user starts the equipment to place the carbon rod inside the furnace body for electrolytic heating. When the equipment is in use, the user starts the motor, and then the motor rotates to drive the second gear to rotate. Then the second gear rotates to drive the first gear to rotate. When the first gear rotates, it drives the rotating block to rotate. When the rotating block rotates, it drives the connecting rod and the rotating rod. When the connecting rod rotates, it drives the connecting arm to move. Then the connecting arm moves to drive the second connecting frame to move and rotate the carbon rod. By providing the rotating device, the carbon rod can be effectively rotated, playing a role in rotating and adjusting the carbon rod, reducing the situation that the carbon rod is difficult to be rotated and adjusted during the use of the equipment, and being inserted into the furnace body at different angles, resulting in the difficulty of quickly adjusting the carbon rod, and improving the practicability of the equipment.

[0015] In the present utility model, by providing an adjusting device, when the device is in use, the user starts the second cylinder, and then the second cylinder operates to drive the first connecting frame to move. Subsequently, the first cylinder moves to drive the positioning block to move. Then, when the positioning block moves, it drives the sliding column to move. When the sliding column moves, it drives the connecting column to move, and when the connecting column moves, it moves the carbon rod. By providing the adjusting device, the first connecting frame can be effectively adjusted and moved, which plays a role in moving and adjusting the first connecting frame. When the device is in use, when it is difficult to generally adjust the first connecting frame, manual rotation adjustment is required. Manual adjustment close to the furnace body is likely to cause burns to the operator. The practicability of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In this embodiment: An adjusting device 7 is arranged on the surface of the first connecting bracket 4. The adjusting device 7 includes a sliding column 71 and a connecting column 72. The sliding column 71 is slidably connected to the inside of the first connecting bracket 4, and the connecting column 72 is fixedly connected to one end of the sliding column 71.

[0030] In this embodiment: By arranging the sliding column 71, the carbon rod 3 can be limited and moved, reducing the situation that the carbon rod 3 is difficult to be limited and moved during the use of the device.
