[0022] The embodiments of this utility model will be described in detail below.

[0023] This utility model discloses a novel residual electrode cooling device. This embodiment provides a closed cooling environment through a shell 1 structure. Automatically sealing first baffles 12 and second baffles 14, respectively installed at the inlet 11 and outlet 13, help maintain the sealed state inside the shell 1. The transport system 2, through the electrical connection between a temperature measuring instrument 22 and the conveyor belt 21, achieves material conveying control based on residual electrode temperature feedback. Combined with the gradient distribution and evenly spaced arrangement of the temperature measuring instrument 22's set value along the cooling direction, the residual electrode can undergo segmented, gradual cooling according to the actual cooling state. The parallel connection of branch pipes 31 and main pipe 32 in the exhaust system 3, combined with an air extractor 33, effectively organizes airflow and improves heat exchange efficiency. The coordinated operation of all components, to a certain extent, improves the automation level and temperature control accuracy of the residual electrode cooling process, while also contributing to energy reduction and optimized working environment. The specific details of this embodiment are as follows: Figure 1 This is a three-dimensional structural schematic diagram of a novel residual electrode cooling device according to this utility model; Figure 2 This is a front view of a novel residual electrode cooling device according to the present invention. Figure 3 This is a top view of a novel residual electrode cooling device according to the present invention.

[0024] In this embodiment, the housing 1 is welded from high-temperature resistant steel plate, and its function is to provide a sealed space to accommodate the residual electrode to be cooled. An inlet 11 at the beginning of the housing 1 is used to transfer the high-temperature residual electrode; an outlet 13 at the end is used to remove the cooled residual electrode. The dimensions of the inlet 11 and outlet 13 are determined according to the specifications of the residual electrode; in this embodiment, they are rectangular openings. A first baffle 12 is rotatably mounted on the housing 1 via a first rotating shaft 16, and its function is to automatically shield and seal the inlet 11 by gravity when not in operation. A second baffle 14 is rotatably mounted via a second rotating shaft 17, and similarly seals the outlet 13 by gravity. High-temperature resistant sealing strips are provided on the contact surfaces of the first baffle 12 and the second baffle 14 with the housing 1; the sealing strip material can be silicone rubber or graphite composite material. In this embodiment, the first baffle 12 and the second baffle 14 adopt a rectangular structure with a thickness of 20 mm; in other embodiments, circular or elliptical structures can also be used, and the thickness can be adjusted within the range of 15-25 mm. Multiple exhaust ports 15 are provided on the top of the housing 1. The multiple exhaust ports 15 are arranged linearly and their function is to discharge the hot gas generated during the residual electrode cooling process. The diameter of the exhaust ports 15 is 200mm. In this embodiment, 8 ports are provided and are distributed equidistantly along the length of the housing. In other embodiments, the number of exhaust ports 15 can be adjusted to 4 or 6 according to the cooling capacity requirements, and the diameter can be selected in the range of 150-250mm.

[0025] The transport system 2 is fixedly installed inside the housing 1 by a bracket, and includes a conveyor belt 21 and multiple temperature measuring instruments 22. The conveyor belt 21 adopts a high-temperature resistant metal mesh belt structure, and the mesh belt material can be 310S stainless steel or heat-resistant alloy steel. Its speed is adjustable within the range of 0.1-1.0 m / min by a variable frequency motor. Multiple temperature measuring instruments 22 are arranged at equal intervals along the conveying direction of the conveyor belt 21 by the bracket, and their function is to monitor the surface temperature of the residual electrodes on the conveyor belt 21 in real time. The temperature measuring instruments 22 adopt infrared temperature measurement modules. In this embodiment, the spacing between the temperature measuring instruments 22 is set to 1.5 meters, with a total of 9 instruments; in other embodiments, the spacing can be adjusted to 1 meter or 2 meters according to process requirements, and the number can be increased or decreased accordingly.

[0026] Specifically, the temperature setpoints of the multiple thermometers 22 decrease in a gradient from the beginning to the end of the housing 1. In this embodiment, the setpoint of the first thermometer at the beginning is 600°C, the setpoint of the last thermometer at the end is 150°C, and the intermediate thermometers are set in an arithmetic gradient of 50°C. In other embodiments, the decreasing trend of the setpoints can also be a non-arithmic curve, for example, a larger gradient in the initial cooling stage (e.g., 80°C) and a smaller gradient in the later cooling stage (e.g., 30°C), which can be specifically set according to the cooling process curve of the residual electrode. The thermometers 22 and the drive motors of the conveyor belt 21 are both electrically connected to a PLC controller. The PLC controller is programmed to receive signals from the thermometers 22 and, when the signal value is lower than the setpoint, control the drive motors to run for a specific duration, thereby causing the conveyor belt 21 to move a set distance L.

[0027] In this embodiment, the distance L is set to be equal to the spacing between the temperature measuring instruments 22, which is 1.5 meters. In other embodiments, L may be less than the spacing between the temperature measuring instruments, such as 1.2 meters or 1.0 meter, but not greater than the spacing between adjacent temperature measuring instruments. This arrangement allows the residual electrode to undergo a gradual cooling process, which helps to achieve a stable and gradual cooling of the residual electrode.

[0028] The exhaust system 3 includes multiple branch pipes 31, which are sealed to the exhaust ports 15 via flanges. The flange sealing surfaces use graphite spiral wound gaskets. The multiple branch pipes 31 are connected to the main pipe 32 in parallel. This parallel exhaust structure ensures that the airflow in each cooling zone does not interfere with each other. The end of the main pipe 32 is connected to an extractor 33, which is a centrifugal fan. The extractor 33 provides a negative pressure environment, thereby accelerating internal gas flow and improving heat exchange efficiency.

[0029] This invention, through the sealed structure of the shell 1, the temperature feedback control mechanism of the transport system 2, and the coordinated operation of the exhaust system 3, can achieve a certain degree of precise control over the cooling process of the residual electrode. The combination of temperature gradient setting and equally spaced temperature measuring instruments allows the residual electrode to undergo a stable cooling process, with temperature uniformity controlled within ±15℃; the parallel exhaust structure helps to improve heat exchange efficiency, and the cooling time is shorter than the natural cooling time.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
