Description

Technical Field

[0001] This utility model relates to the technical field of molten iron ladle processing equipment, specifically a molten iron ladle drying device. Background Technology

[0002] The molten iron ladle drying device is a crucial piece of equipment in the steel production process. Its main purpose is to dry the moisture inside the ladle before it is put into use, preventing accidents such as molten iron splashing or explosions caused by moisture vaporizing at high temperatures during subsequent use. It also improves the service life of the ladle and increases production efficiency. The existing technology is authorized by publication number CN 221764140. U's patent discloses a ladle drying device, including a base, a pedestal fixedly connected to the upper surface of the base, a column fixedly connected to the upper surface of the pedestal, a support plate fixedly connected to the upper surface of the column, a hydraulic press fixedly connected to the lower surface of the support plate, a hydraulic column fixedly connected to the lower surface of the hydraulic press, and a drying assembly fixedly connected to the lower surface of the hydraulic column. Several flame nozzles are fixedly connected to the lower surface and sides of the drying assembly. While this device can dry the ladle by spraying flames from the nozzles, the nozzle positions are fixed. The flames from the fixed-position nozzles generate excessively high temperatures in localized areas, while other areas cannot fully utilize the heat. This uneven heat distribution reduces the thermal efficiency of the entire drying process. Subsequently, during the drying process, due to insufficient drying in some areas, the drying time needs to be extended to ensure the entire ladle is dry. This not only increases energy consumption but also affects production efficiency. Therefore, we propose a ladle drying device. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a molten iron ladle drying device, including a base 1, an mounting seat 3 slidably connected to the upper right side of the base 1, a support plate 4 provided at the upper end of the mounting seat 3, and a drying mechanism 5.

[0022] Drying mechanism 5 includes a transmission assembly 57, an mounting pipe 52, a hot air conveying box 53, and an exhaust port 54. The mounting pipe 52 is slidably connected to a groove on the right side of the lower end of the support plate 4. The lower end of the mounting pipe 52 is connected to a clearance groove in the middle of the upper end of the hot air conveying box 53. Evenly distributed exhaust ports 54 are respectively provided in the middle and lower ends of the outer arc surface of the hot air conveying box 53. The transmission assembly 57 is located on the upper end of the support plate 4, and the hot air conveying box 53 is driven by the transmission assembly 57. Structure 5 also includes a protective cover 51, uprights 55, a connecting plate 56, and an adjusting rod 58. The protective cover 51 is located on the right side of the upper end of the support plate 4. Uprights 55 are respectively installed between the top wall of the protective cover 51 and the upper end of the support plate 4. The connecting plate 56 is located at the upper end of the mounting tube 52. The upper ends of the uprights 55 are slidably connected to corresponding sliding holes at the lower end of the connecting plate 56. The adjusting rod 58 is located at the middle of the front end of the connecting plate 56. A transmission assembly 57 is installed in conjunction with the adjusting rod 58. 57 includes a mounting rod 571, a transmission plate 572, an output rod 573, a central wheel 574, and a drive rod 575. The mounting rod 571 is rotatably connected to the left side of the front wall of the protective cover 51. The transmission plate 572 is located in the middle of the outer arc surface of the mounting rod 571. Adjustment grooves and connecting grooves are respectively provided on the left and right sides of the front end of the transmission plate 572. The front end of the adjustment rod 58 is located inside the connecting groove. The output rod 573 is rotatably connected to the left side of the rear wall of the protective cover 51. The central wheel 574 is located on the front side of the outer arc surface of the output rod 573. The drive rod 575 is located on the lower side of the front end of the central wheel 574. The front end of the drive rod 575 is located inside the adjustment groove. Through the cooperation of the transmission plate 572 and the drive rod 575, the exhaust port 54 can be driven to perform vertical reciprocating motion, so that the hot air can cover the inner wall of the molten iron ladle more evenly, improve the uniformity of the drying effect, solve the problem of reduced thermal efficiency of the entire drying process due to uneven heat distribution, and shorten the time required to dry the molten iron ladle.

[0023] It also includes a control switch group 2, which is located at the front end of the base 1. The input end of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0024] Among them: a motor 6 is provided on the left side of the rear end of the protective cover 51. The front end of the output shaft of the motor 6 is fixedly connected to the rear end of the output rod 573. The input end of the motor 6 is electrically connected to the output end of the control switch group 2. The motor 6 starts to run through the control switch group 2. The output shaft of the motor 6 will drive the central wheel 574 to rotate through the output rod 573.

[0025] The heating box 7 is located on the left side of the lower end of the support plate 4, and is situated to the right of the mounting base 3. Filters 8 are installed in the air inlets on the left sides of both the front and rear ends of the heating box 7. A fan 9 is located on the left side inside the heating box 7, with both filters 8 located to the left of the fan 9. Three electric heating wires 10 are installed on the right side inside the heating box 7. The air outlet located in the middle of the right end of the heating box 7 and the conveying port located on the left side of the outer arc surface of the mounting pipe 52 are connected by a conveying hose 11. The input ends of the fan 9 and the electric heating wires 10 are electrically connected to the output ends of the control switch group 2. The control switch group 2 controls the flow of the heating box 7. With the control of switch group 2, the fan 9 and the electric heating wire 10 start to operate. During operation, the fan 9 generates suction, and the outside air enters the heating box 7 after being filtered by the filter screen 8. Then, the air is heated by the electric heating wire 10. The electric heating wire 10 is a nickel-chromium alloy heating wire with high resistivity, which can heat up quickly after being powered on. The heated air is then injected into the installation pipe 52 through the delivery hose 11, and then into the hot air delivery box 53 through the installation pipe 52. Finally, the heated air is discharged through the exhaust port 54, thereby drying the molten iron ladle.

[0026] Among them, electric push rods 16 are respectively provided on the front and rear sides of the bottom wall of the base 1. The upper ends of the telescopic ends of the two electric push rods 16 are fixedly connected to the lower end of the mounting base 3. The input ends of the electric push rods 16 are electrically connected to the output ends of the control switch group 2. By adjusting the control switch group 2, the electric push rods 16 start to run, and the telescopic ends of the electric push rods 16 shorten, so that the electric push rods 16 drive the support plate 4 to move downward through the mounting base 3. The support plate 4 will drive the hot air conveying box 53 to move downward, so that the hot air conveying box 53 extends into the interior of the molten iron ladle.

[0027] The support plate 4 has two fixing rods 12 on its lower front and rear sides. The lower ends of the two fixing rods 12 are fixedly connected to the upper end of the cover plate 13. The mounting pipe 52 is slidably connected to the mounting groove in the middle of the upper end of the cover plate 13. The cover plate 13 is located below the conveying hose 11. The lower end of the cover plate 13 is provided with evenly distributed exhaust holes 14. The lower end of the cover plate 13 is provided with a rubber pad 15. The exhaust holes 14 are all located inside the rubber pad 15. The cover plate 13 can isolate the molten iron ladle from the external environment and prevent heat from being lost to the surrounding air through the ladle opening. This can keep the temperature inside the molten iron ladle relatively stable and make the heat more concentrated for drying the moisture inside the ladle. During the drying process, the moisture inside the molten iron ladle will gradually evaporate into water vapor. The exhaust holes 14 can discharge this water vapor from the molten iron ladle in time to prevent water vapor from accumulating inside the ladle and avoid damage to the molten iron ladle due to excessive water vapor pressure.

[0028] The working principle of the molten iron ladle drying device provided by this utility model is as follows: During the use of the molten iron ladle drying device, the molten iron ladle to be dried is moved to the lower side of the hot air conveyor box 53 by external equipment. Then, by controlling the switch group 2, the electric push rod 16 starts to run, and the telescopic end of the electric push rod 16 shortens, so that the electric push rod 16 drives the support plate 4 to move downward through the mounting base 3. The support plate 4 drives the hot air conveyor box 53 to move downward, so that the hot air conveyor box 53 extends into the interior of the molten iron ladle. When the cover plate 13 contacts the opening at the upper end of the molten iron ladle through the rubber pad 15, the electric push rod 16 stops running by controlling the switch group 2, and the fan 9 and the electric heating wire 10 start to run. During the process, suction is generated, and external air enters the heating chamber 7 after being filtered through the filter screen 8. The air is then heated by the electric heating wire 10, a nickel-chromium alloy wire with high resistivity, which heats up rapidly after being energized. The heated air is then injected into the installation pipe 52 through the delivery hose 11, and then into the hot air delivery box 53. Finally, the heated air is discharged through the exhaust port 54, thus drying the molten iron ladle. The cover plate 13 isolates the molten iron ladle from the external environment, preventing heat loss to the surrounding air through the ladle opening. This maintains a relatively stable temperature inside the ladle, allowing the heat to be more concentrated for drying the moisture inside. During the process, the moisture inside the molten iron ladle gradually evaporates into water vapor. The vent 14 allows this water vapor to be discharged from the ladle in a timely manner, preventing water vapor accumulation and avoiding damage to the ladle due to excessive steam pressure. During the operation of the blower 9, the motor 6 starts running through the control switch group 2. The output shaft of the motor 6 drives the central wheel 574 to rotate via the output rod 573. The central axes of the output rod 573 and the central wheel 574 are the same. When the central wheel 574 rotates, it drives the drive rod 575 to rotate around the axis of the central wheel 574. Because the axes of the drive rod 575 and the central wheel 574 do not coincide, the drive rod 575 will experience lateral and vertical displacement during its circular motion. At this time, the drive rod 575 will... Inside the adjusting groove, relative sliding and relative rotation occur. When the drive rod 575 rotates upward, the transmission plate 572, pushed by the drive rod 575, rotates upward around the mounting rod 571. At this time, the adjusting rod 58 slides and rotates relative to the adjusting groove inside the adjusting groove, thereby causing the transmission plate 572 to drive the connecting plate 56 upward via the adjusting rod 58. The connecting plate 56 then drives the hot air conveying box 53 upward via the mounting pipe 52, which in turn drives the exhaust port 54 upward. When the drive rod 575 rotates downward, the transmission plate 572, pushed by the drive rod 575, rotates downward around the mounting rod 571 to reset. At this time, the adjusting rod 58 both slides and rotates relative to the adjusting groove inside the adjusting groove.This causes the transmission plate 572 to move the connecting plate 56 downwards and reset via the adjusting rod 58. The connecting plate 56 then moves the hot air conveyor box 53 downwards and reset via the mounting pipe 52. The hot air conveyor box 53 then moves the exhaust port 54 downwards and reset, thereby causing the exhaust port 54 to perform a vertical reciprocating motion, ensuring the uniformity of the molten iron ladle drying process.

[0029] It is worth noting that the motor 6 disclosed in the above embodiments can be ECMA-C20604RS, the fan 9 can be ME92252V1-000C-A99, the electric push rod 16 can be YRJ095, and the control switch group 2 is provided with control buttons corresponding to the motor 6, fan 9, electric heating wire 10 and electric push rod 16 for controlling their switching.
