[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Please seeFigures 1 to 5 This embodiment provides a carbon car bottom furnace water seal lifting device, which includes a water seal trough 1, a support base 2, a swing arm 3, a push shaft 4, and a drive mechanism 5.

[0025] The water seal trough 1 is movably placed inside the kiln. The water seal trough 1 is trough-shaped with an opening at the top, and its dimensions are slightly larger than those of the car-bottom kiln. Multiple support seats 2 are installed at intervals on both sides of the water seal trough 1. A swing arm 3 is rotatably mounted on the support seat 2 at its center, and its upper part is hinged to the side of the water seal trough 1. Two push shafts 4 are connected to the lower parts of the multiple swing arms 3 on the same side of the water seal trough 1, respectively. A drive mechanism 5 can drive the axial movement of the push shafts 4. Through the axial movement of the push shafts 4, the multiple swing arms 3 can be driven to move synchronously, thereby realizing the raising or lowering of the water seal trough 1.

[0026] For ease of operation, the drive mechanism 5 includes a support frame 51, a rotating shaft 52, a rotary arm 53, a transmission component 54, and a drive motor 55. Two support frames 51 are mounted on the outside of one end support seat 2. A rotating shaft 52 is rotatably mounted on the two support frames 51. A rotary arm 53 is provided on each side of the rotating shaft 52. One end of the rotary arm 53 is mounted radially on the rotating shaft 52 via a first support 56 (one end of the rotary arm 53 is hinged to the first support 56, and the first support 56 is fixed on the rotating shaft 52). The other end is hinged to the push shaft 4. The rotating shaft 52 is connected to the drive motor 55 via the transmission component 54. Thus, the drive motor 55 and the transmission component 54 can drive the rotation of the rotating shaft 52 and the rotary arm 53, thereby driving the reciprocating movement of the push shaft 4.

[0027] For ease of control, the transmission component 54 includes a worm gear mechanism 541, a driving sprocket 542, a driven sprocket 543, a transmission chain 544, and a transmission link 545. The driving sprocket 542 is mounted on the output shaft of the drive motor 55, and the driven sprocket 543 is mounted on the worm gear shaft of the worm gear mechanism 541. The transmission chain 544 connects the driving sprocket 542 and the driven sprocket 543 to transmit power to the worm gear mechanism 541, driving the worm gear to rotate and the worm to move. One end of the transmission link 545 is mounted on the rotating shaft 52 via a second support 546 (one end of the transmission link 545 is hinged to the second support 546, which is fixed to the rotating shaft 52), and the other end is hinged to the outer end of the worm of the worm gear mechanism. This allows the movement of the worm to be converted into the rotation of the rotating shaft 52. This structure allows for precise control of the rotation angle of the rotating shaft 52, and the worm gear mechanism has a self-locking function to maintain the lifting state.

[0028] For ease of operation, a limit switch is installed on one side of the water seal tank 1, which can be used to control the lifting height of the water seal tank 1.

[0029] The working principle of the carbon car bottom furnace water seal lifting device is as follows:

[0030] First, the furnace car carrying the roasting electrodes is moved into the furnace, positioned directly above the water seal trough 1. Second, after the furnace car is loaded, the water seal trough 1 is raised, partially immersing the water inside at the bottom feed gate of the furnace. Then, the furnace is ignited and the finished product is awaited for roasting. This invention, by raising and lowering the water seal trough 1, isolates it from the outside air during combustion in the furnace, achieving insulation by separating the air from the flue gas reaching temperatures up to 850°C. Compared to existing technologies, this invention improves the utilization rate of the furnace temperature, effectively reduces heat loss, and achieves energy conservation. Furthermore, this invention uses multiple support seats 2, swing arms 3, and push shafts 4 to control the lifting of the water seal trough 1, ensuring uniform force distribution and preventing jamming.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
