Description

Technical Field

[0001] This utility model relates to the field of converter steelmaking technology, specifically to a furnace repair device that resists deformation. Background Technology

[0002] The converter lining plays a crucial role in protecting the furnace body and extending its service life. Impacts from the charging charge and chemical reactions during smelting often cause damage to the converter lining. Furthermore, the slag layer formed during slag splashing is uneven, necessitating frequent repairs. Converter repair primarily employs a combination of brick and material patching to fill damaged areas and achieve a safe lining thickness. The repair process involves numerous collaborative steps that require comprehensive organization. Repair tools, often long and thin rods exceeding eight meters in length, are used to deliver repair materials to the damaged areas. Prolonged repair work in high-temperature environments can lead to bending and deformation, affecting the subsequent delivery of repair materials and the accuracy of the material placement. This necessitates multiple adjustments, resulting in low efficiency. Additionally, prolonged repair work causes significant temperature drops within the furnace, hindering the sintering of the refractory material and impacting the quality of the repair. Therefore, this application proposes a deformation-resistant repair device to address these issues. Utility Model Content

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0025] like Figures 1 to 6The diagram illustrates a deformation-resistant furnace repair device, comprising a feeding mechanism 1. The feeding mechanism 1 includes a solid conveying channel 1-1 and a powder-liquid conveying channel 1-2, arranged vertically. The solid conveying channel 1-1 is used to feed furnace repair bricks, and the powder-liquid conveying channel 1-2 is used to convey powder or liquid furnace repair materials. A cooling water channel 1-3 is provided between the solid conveying channel 1-1 and the powder-liquid conveying channel 1-2, and the cooling water channel 1-3 surrounds the outer periphery of the powder-liquid conveying channel 1-2 to ensure uniform temperature of the powder or liquid within the channel, thus ensuring a uniform furnace protective layer formed during sintering after filling. The powder-liquid conveying channel 1-2 can be traversed by cooling water. The material slides back and forth within channel 1-3. When conveying powder or liquid, it slides outward to deliver the furnace repair material to the damaged position, without being restricted by the solid conveying channel 1-1 above. When the solid conveying channel 1-1 delivers the furnace repair bricks, the powder and liquid conveying channel 1-2 retracts into the cooling water channel 1-3, which does not hinder the delivery of the furnace repair bricks. The cooling water channel 1-3 is connected to the chiller 4 set on the mobile trolley 3 through the hose 2. The feeding mechanism 1 is fixed on the mobile trolley 3 through the adjusting mechanism 5. The integrated chiller 4 provides circulating cooling water, which is convenient for moving between different converters and can carry out furnace repair operations continuously for a long time.

[0026] like Figure 5 and Figure 6As shown, the solid conveying channel 1-1 and the cooling water channel 1-3 are fixedly welded together. The solid conveying channel 1-1 is a U-shaped trough with an open top. The furnace lining repair bricks are fed to the damaged area of ​​the furnace lining along the U-shaped trough. The discharge end of the solid conveying channel 1-1 is equipped with a downwardly inclined guide plate 1-1-1, which is located at the bottom end of the U-shaped trough. The furnace lining repair bricks slide along the guide plate 1-1-1 to the damaged area of ​​the furnace lining. The powder-liquid conveying channel 1-2 is a circular pipe that passes through the cooling water channel 1-3. The length of the powder-liquid conveying channel 1-2 is greater than the length of the cooling water channel 1-3. The powder or liquid is conveyed to the damaged area of ​​the furnace lining along the circular pipe. One end of the powder-liquid conveying channel 1-2 is equipped with an upward-opening feeding port 1-2-1, and the other end is equipped with a discharge port 1-2-2. The discharge port 1-2-2 has a downward-sloping angle to facilitate the flow of furnace lining repair material. The cooling water channel 1-3 includes blocking plates 1-3-1 located below both ends of the solid conveying channel 1-1. On the two blocking plates 1-3-1, an outer cylinder 1-3-2, an inner cylinder 1-3-3, and a sealing cylinder 1-3-4 are concentrically arranged from the outside in. The outer cylinder 1-3-2 is welded to the solid conveying channel 1-1 as a single unit. The inner cylinder 1-3-3 is welded to the blocking plates 1-3-1 at both ends. The two sealing cylinders 1-3-4 are also welded to the two blocking plates 1-3-1 respectively. The powder-liquid conveying channel 1-2 passes through the sealing cylinders 1-3-4 and can slide back and forth. The gap between the outer cylinder 1-3-2 and the inner cylinder 1-3-3 is the water inlet channel, and the water inlet pipe is connected to the water inlet channel. The gap between the inner cylinder 1-3-3 and the powder-liquid conveying channel 1-2 is the water return channel, and the water return pipe is connected to the water return port. A water return hole is provided at the discharge end between the water inlet channel and the water return channel.

[0027] like Figures 1 to 4As shown, the adjustment mechanism 5 includes a lifting cylinder 5-1, a rotating cylinder 5-2, and a feeding cylinder 5-3. The lifting cylinder 5-1 and the rotating cylinder 5-2 are connected to the feeding mechanism 1 through the support assembly 6, which can push the feeding mechanism 1 to move up and down and rotate around the axis. The feeding cylinder 5-3 is connected between the powder and liquid conveying channel 1-2 and the cooling water channel 1-3, which can push the powder and liquid conveying channel 1-2 to move back and forth. The support assembly 6 includes a hinge 6-1, a support plate 6-2, and side brackets 6-3. Two side brackets 6-3 are symmetrically fixed on both sides of the solid conveying channel 1-1. The support plate 6-2 and hinge 6-1 are sequentially fixed below the side brackets 6-3 by bolts. A lifting cylinder 5-1 is hinged to the hinge 6-1 to drive the feeding mechanism 1 to rise and fall. A rotating cylinder 5-2 is hinged below the support plate 6-2 to drive the feeding mechanism 1 to rotate around the axis of the hinge 6-1. The feeding cylinder 5-3 is parallel to one side of the powder-liquid conveying channel 1-2 and can drive its reciprocating motion. A guide rod 5-4 is also provided on one side of the powder-liquid conveying channel 1-2. The guide rod 5-4 is symmetrically arranged with the feeding cylinder 5-3, ensuring the coaxiality of the powder-liquid conveying channel 1-2 during reciprocating motion. The mobile trolley 3 is equipped with casters at the bottom, two handrails at the top, and a hydraulic pump station connected to the adjusting mechanism 5.

[0028] Operating Procedure: The operator pushes the mobile trolley 3 to move the furnace repair device to the converter, starts the chiller to circulate the cooling water, and starts the lifting cylinder 5-1 of the adjusting mechanism 5 to make the height of the feeding mechanism 1 suitable for the converter opening. The feeding mechanism 1 is then inserted into the converter. The feeding angle of the feeding mechanism 1 is adjusted by rotating the cylinder 5-2 to feed the damaged parts of the converter. Powder and liquid furnace repair materials are fed through the powder-liquid conveying channel 1-2, while furnace repair bricks are fed through the solid conveying channel 1-1. When feeding powder and liquid, the extension length of the powder-liquid conveying channel 1-2 can be adjusted by the feeding cylinder 5-3 to make it easier to deliver the furnace repair materials to the correct position.
