[0002] With the rapid development of the steel industry, traditional ladle baking devices used for transfer ladle baking have gradually been unable to meet the current production needs of high efficiency, energy saving and environmental protection. Traditional ladle baking devices usually use coal gas, natural gas, liquefied petroleum gas, diesel and other fuel combustion heating methods. This heating method requires the laying of corresponding oil and gas pipelines to transport fuel, which has a large infrastructure workload, inconvenient maintenance, and the risk of oil and gas leakage; at the same time, the combustion heating method has low thermal energy utilization, and part of the heat energy is discharged with the flue gas, causing heat energy loss, which is not conducive to energy saving and environmental protection; in addition, the high-temperature flue gas is turbulent and uneven in the transfer ladle, which often causes uneven heating temperature in the ladle, poor baking quality, and even low temperature at the bottom of the transfer ladle, resulting in blockage of the water outlet of the transfer ladle, resulting in poor pouring or no pouring, forcing the aluminum liquid to return to the furnace, affecting the production progress. Furthermore, traditional ladle baking devices are mostly fixed settings, do not have a height adjustment function, have poor applicability, and cannot meet the heating needs of different transfer ladle.

[0003] Based on this, developing a new type of bag baking device for application in actual production to improve the heating efficiency of transfer bags, reduce energy consumption, improve heating uniformity, and improve applicability is a technical problem that needs to be solved urgently.

The top of the electric heater 1 is connected to a cover 2, and the cover 2 is arranged corresponding to the open end of the transfer bag. The cover 2 is provided with a connection terminal 21 connected to the electric heater 1 for connecting to a power source. When in use, the electric heater 1 protected by the protective steel barrel 11 is extended into the transfer bag, and the cover 2 is closed on the open end of the transfer bag. The connection terminal 21 is connected to a power source to heat and raise the temperature of the transfer bag.

[0024] This embodiment uses an electric heater 1 as a heat source to bake and heat the transfer bag. Compared with the traditional oil and gas combustion heating method, the electric heating method has the natural advantages of energy saving, environmental protection, and convenient energy use. It eliminates the trouble of laying oil and gas pipelines, avoids the heat loss caused by the emission of heat energy with the flue gas, and improves the utilization rate of heat energy and heating efficiency. At the same time, the barrel-shaped electric heater 1 improves the problem of uneven heating of the transfer bag caused by the uneven high-temperature flue gas in the oil and gas heating method, improves the heating uniformity, and ensures the continuous and stable production operation. The setting of the protective steel barrel 11 effectively protects the electric heater 1 and extends its service life. The setting of the cover 2 reduces the heat loss of the transfer bag and further improves the heating efficiency.

[0025] As a preferred embodiment, the protective steel barrel 11 is filled with thermal insulation rock wool 12, so that the heat generated by the electric heater 1 is efficiently transferred to the transfer bag, thereby achieving the purpose of saving energy. Furthermore, the cover body 2 is also filled with thermal insulation rock wool 12 to improve the thermal insulation performance of the cover body 2, further improve the heating efficiency, and save energy consumption.

[0026] Preferably, a thermocouple 13 is provided on the cover body 2 corresponding to the transfer bag, so that the operator can monitor the heating temperature of the transfer bag in real time and make corresponding adjustments in time to ensure the baking quality of the bag baking machine.

[0027] In a further embodiment, the bag baking device further includes a lifting mechanism corresponding to the cover 2, which is used for adjusting the height of the bag baking device, so as to facilitate the taking and placing of the bag baking device, and at the same time facilitate the baking operation of transfer bags of different specifications, thereby improving applicability. The lifting mechanism includes a frame 3, and the frame 3 is connected with a support arm 31 for hanging the cover 2, and the support arm 31 is adjustable in the vertical direction of the frame 3. When in use, the electric heater 1 is hung on the support arm 31 through the cover 2, and the height adjustment of the bag baking device can be achieved by adjusting the positioning height of the support arm 31 in the vertical direction of the frame 3, thereby facilitating the taking and placing of the bag baking device, and can be lifted to the corresponding position corresponding to the height of transfer bags of different specifications, so that the bag baking device provided by the utility model has a certain versatility and can meet the heating requirements of different transfer bags.

[0028] Preferably, the support arm 31 is slidably connected to the frame body 3 via a slide 32, so as to adjust the position of the support arm 31 in the vertical direction of the frame body 3. Specifically, the tail end of the support arm 31 is connected to the slide 32, and a guide rail 33 is provided on the frame body 3 corresponding to the slide 32, so that the support arm 31 can adjust its height in the vertical direction of the frame body 3 through the sliding cooperation between the slide 32 and the guide rail 33.

[0030] Furthermore, a power motor 34 is provided on the top of the frame 3, and the power motor 34 is connected to the slide 32 to provide power for the lifting and lowering adjustment of the slide 32. Specifically, a lifting chain 35 is connected to the slide 32, and a sprocket 36 is connected to the output end of the power motor 34, and the sprocket 36 meshes with the lifting and lowering chain 35 to achieve the lifting and lowering adjustment of the slide 32.

[0031] Preferably, the rear end of the slide 32 is provided with a back clamping roller 4 corresponding to the frame 3 to resist the turning torque generated by the slide 32 on the guide rail 33. Specifically, a clamping shaft 41 runs through the slide 32 sandwiched between the two sides of the frame 3, and the back clamping roller 4 is rotatably connected to the clamping shaft 41 and clamped on the frame 3. This embodiment optimizes the structural force and further improves the operation stability.

[0032] Furthermore, a tension rod 42 is provided on the slide 32 corresponding to the clamping shaft 41, which is used to adjust the clamping force of the back clamping roller 4. One end of the tension rod 42 is sleeved on the clamping shaft 41, and the other end passes through the slide ear plate 43 and is screwed to the adjustment nut. By rotating the adjustment nut to loosen or tighten, the tension rod 42 is driven to pull the clamping shaft 41 away from or close to the frame 3, so as to adjust the clamping force of the back clamping roller 4 on the frame 3, so as to keep the structure under reasonable stress.

[0033] The frame 3 is provided with a limit stopper 37 corresponding to the guide rail 33, which is used for stopping the slide 32 at the limit position to prevent the slide 32 from derailing.
