Description

Technical Field

[0001] This utility model relates to the field of ladle baking technology, and in particular to a regenerative natural gas molten steel ladle baking machine. Background Technology

[0002] A ladle heat exchanger is a device used to heat steel ladles after they are newly built and before they are filled with molten steel. Both steel ladles and aluminum ladles are storage and transfer devices for high-temperature liquid metals. Some molten steel requires higher temperatures. The operating temperature of the steel ladle lining is 1500-1600℃, and the operating temperature of the aluminum ladle lining is 650-700℃. Both steel ladles and aluminum ladles need to be heated before use. Otherwise, the molten steel or aluminum will cool down rapidly after entering the ladle due to contact with the ladle body, which will lead to a decrease in production quality. Therefore, during the transfer process, the ladle is generally heated by a heat exchanger to keep the molten metal at a certain temperature. Conventional heat exchangers typically heat to below 1100 degrees Celsius.

[0003] Most existing baking ovens are equipped with a lifting mechanism, which is usually fixed to the baking oven with bolts. However, if it is necessary to inspect or replace the baking oven, and the bottom of the lifting mechanism is a fixed structure, it is not convenient to quickly disassemble and move the baking oven if it needs to be moved, so the applicability is not high.

[0004] Therefore, in view of the existing ladle baking machine and lifting mechanism, which are fixedly connected to the ladle baking machine with bolts, it is not convenient to quickly disassemble and move the ladle baking machine when it is necessary to inspect or replace the ladle baking machine, and the applicability is not high. Therefore, a regenerative natural gas ladle baking machine can be designed. By rotating the first knob and the second knob respectively, rotating the first knob facilitates the quick connection of the mounting frame with ladle heating furnaces of different sizes, and rotating the second knob moves the displacement seat out of the bottom of the mounting frame, which facilitates the displacement of the mounting frame through the displacement seat. Utility Model Content

[0005] To overcome the problem that existing baking ovens and lifting mechanisms are fixedly connected to the baking oven with bolts, but when it is necessary to inspect or replace the baking oven, it is not convenient to quickly disassemble and move the baking oven, resulting in low applicability.

The bottom end of the lower fixed frame is provided with a displacement seat. The displacement seat includes rollers, a connecting seat and a lifting crossbar. The connecting seat is located on both sides of the lifting crossbar, and the rollers are located on both sides of the bottom end of the connecting seat.

[0007] By rotating the first knob and the second knob respectively, rotating the first knob facilitates quick connection of the mounting frame with steel ladle heating furnaces of different sizes, and rotating the second knob moves the displacement seat out of the bottom of the mounting frame, making it easier to move the mounting frame through the displacement seat.

[0008] Preferably, there are two clamping blocks, and the lower part of the clamping block is provided with a movable groove on the top surface of the upper support plate. The bottom end of the clamping block extends through the movable groove to the inner side of the upper support plate.

[0009] Preferably, the bottom end of one of the clamping blocks is located on the inner wall of the upper support plate and is provided with a first lead screw. One end of the first lead screw passes through the two clamping blocks and extends to the other end of the inner wall of the upper support plate. The first lead screw meshes with the two clamping blocks.

[0010] Preferably, the first lead screw is a double-threaded lead screw, and the threads at both ends of the first lead screw are symmetrical about the first knob. One end of the first knob extends through the upper support plate to the front end of the first lead screw. A bevel gear is provided at the intersection of the first knob and the first lead screw, and the first knob and the first lead screw are connected by bevel gear transmission.

[0011] Preferably, the bottom end of the lifting crossbar is provided with a lifting groove inside the lower fixed frame, and the bottom end of the inner wall of the lifting groove is provided with a second lead screw.

When the second knob is rotated, the second knob causes the displacement seat to move out of the inner side of the lower fixed frame through the second lead screw. The bottom end of the displacement seat is equipped with rollers, which facilitates the displacement of the mounting frame through the rollers. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides a technical solution: a regenerative natural gas ladle baking device, including a ladle heating furnace 1, a baking cover 2 at the top of the ladle heating furnace 1, a flame nozzle at the bottom of the baking cover 2, reinforcing rods 3 fixedly installed at both ends of the baking cover 2, a heat preservation block 7 at the top of the baking cover 2, temperature sensors 8 on both sides of the top of the heat preservation block 7, a mounting frame 4 at the bottom of the ladle heating furnace 1, a blower 5 and an induced draft fan 6 at the top of the mounting frame 4 at the rear end of the ladle heating furnace 1, an air inlet pipe installed at one end of the blower 5 and the induced draft fan 6, and the blower 5 and the induced draft fan 6 are connected to the ladle heating furnace 1 through the air inlet pipe, thereby heating the ladle through the baking device;

[0024] Please see Figures 2-3 In this embodiment, the mounting frame 4 includes an upper support plate 401, a lower fixing frame 402, and a hydraulic scissor-type support frame 403. The hydraulic scissor-type support frame 403 is located at the center of the opposite surfaces of the upper support plate 401 and the lower fixing frame 402. Both ends of the hydraulic scissor-type support frame 403 extend to the inner sides of the upper support plate 401 and the lower fixing frame 402, respectively. Clamping blocks 9 are provided on the top surface of the upper support plate 401 on both sides of the ladle heating furnace 1. There are two clamping blocks 9. Below the 9, on the top surface of the upper support plate 401, there is a movable groove. The bottom end of the clamping block 9 extends through the movable groove to the inner side of the upper support plate 401. The bottom end of one of the clamping blocks 9 is provided with a first screw rod 11 on the inner wall of the upper support plate 401. One end of the first screw rod 11 extends through the two clamping blocks 9 to the other end of the inner wall of the upper support plate 401. The first screw rod 11 and the two clamping blocks 9 mesh with each other, thereby facilitating the mounting frame 4 to fix and connect the ladle heating furnace 1 through the clamping blocks 9.

[0025] Please see Figures 3-4In this embodiment, the front ends of the upper support plate 401 and the lower fixing frame 402 are respectively provided with a first knob 10 and a second knob 13. The rear ends of the first knob 10 and the second knob 13 extend through to the inner side of the upper support plate 401 and the lower fixing frame 402, respectively. The first lead screw 11 is a double-threaded lead screw, and the threads at both ends of the first lead screw 11 are symmetrical about the first knob 10. One end of the first knob 10 extends through the upper support plate 401 to the front end of the first lead screw 11. A bevel gear 15 is provided at the intersection of the first knob 10 and the first lead screw 11. The lead screw 11 is connected via a bevel gear 15. A displacement seat 12 is provided at the bottom of the lower fixed frame 402. The displacement seat 12 includes rollers 1201, a connecting seat 1202, and a lifting crossbar 1203. The connecting seat 1202 is located on both sides of the lifting crossbar 1203, and the rollers 1201 are located on both sides of the bottom of the connecting seat 1202. A lifting groove is provided at the bottom of the lifting crossbar 1203 inside the lower fixed frame 402. A second lead screw 14 is provided at the bottom of the inner wall of the lifting groove. The top end of the second lead screw 14 extends through the lifting crossbar 1203 to the outer side of the top of the lifting groove. The crossbar 1203 and the second lead screw 14 mesh with each other. One end of the second knob 13 extends through the lower fixing frame 402 to one side of the top of the second lead screw 14. Both the second knob 13 and the second lead screw 14 are provided with bevel gears 15 at their intersection. The second knob 13 and the second lead screw 14 are connected by the bevel gears 15. By rotating the first knob 10 and the second knob 13 respectively, when the first knob 10 rotates, it drives the first lead screw 11 to rotate via the bevel gears 15. Since the first lead screw 11 meshes with the two clamping blocks 9, it thus... When the first knob 10 is rotated, it drives the two clamping blocks 9 to move relative to each other, which facilitates the quick connection between the mounting frame 4 and the steel ladle heating furnace 1 of different sizes. When the second knob 13 is rotated, it drives the second lead screw 14 to rotate. Since the second lead screw 14 is engaged with the displacement seat 12, the displacement seat 12 is displaced out of the inner side of the lower fixed frame 402 when the second knob 13 is rotated. The bottom end of the displacement seat 12 is provided with a roller 1201, which facilitates the displacement of the mounting frame 4 through the roller 1201.

[0026] During operation, the ladle heating furnace 1 is placed on top of the mounting frame 4. Then, by rotating the first knob 10 and the second knob 13, the first knob 10 drives the first lead screw 11 to rotate via the bevel gear 15. Since the first lead screw 11 meshes with the two clamping blocks 9, the rotation of the first knob 10 causes relative movement between the two clamping blocks 9, facilitating quick connection between the mounting frame 4 and ladle heating furnaces 1 of different sizes. Furthermore, by rotating the second knob 13, the second lead screw 11 is driven to rotate via the bevel gear 15. The rod 14 rotates, and since the second lead screw 14 meshes with the displacement seat 12, when the second knob 13 rotates, the displacement seat 12 moves out of the inner side of the lower fixed frame 402. The bottom end of the displacement seat 12 is provided with a roller 1201, which facilitates the displacement of the mounting frame 4 through the roller 1201. Then, the molten steel ladle to be heated is placed at the flame nozzle at the bottom end of the ladle cover 2. Then, the power is turned on and the device is started. The blower 5 and the induced draft fan 6 work together to mix and heat the natural gas in the molten steel ladle heating furnace 1. Then, flames are sprayed out through the flame nozzle to heat the molten steel ladle.

[0027] Through the above steps, by rotating the first knob 10 and the second knob 13 respectively, it is easy to quickly connect the mounting frame 4 with the steel ladle heating furnace 1 of different sizes, and the displacement seat 12 is displaced from the bottom of the mounting frame 4, so that the mounting frame 4 can be moved by the displacement seat 12. This solves the problem that the existing baking machine and lifting mechanism are fixedly connected to the baking machine by bolts, but if it is necessary to inspect the inside of the baking machine or replace the baking machine, it is not easy to quickly disassemble and move the baking machine, and the applicability is not high.
