AI Technical Summary
When the existing electric furnace electrode clamp is running at high power, the problem of overheating of the contact points between the electrode and the clamp often occurs, resulting in poor cooling effect, which may cause arc flash fire, damage the equipment, and affect production efficiency and safety.
A new type of electric furnace electrode clamp cooling device is designed, adopting multiple water flow channel circulation groups, water inlet pipes and water outlet pipes. The water flow channel is welded by iron sheets. The water inlet pipes and water outlet pipes are surrounded by the top and bottom of the water flow channel circulation group. The independent water inlet and drainage design reduces the cold water stroke and improves the cooling effect.
By increasing the contact surface between the water flow channel and the clamp and the independent water circulation design, the cooling effect is significantly improved, ensuring stable operation of the electric furnace, improving overall performance and production efficiency, and reducing the risk of fire.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrode clamp cooling, in particular to a novel electric furnace electrode clamp cooling device. Background Art
[0002] Electric furnaces are widely used in metallurgical processes, and their efficiency and safety directly affect the cost and quality of production. As an important component of the electric furnace, the working state of the electrode clamp has an important impact on the overall performance of the electric furnace. With the continuous improvement of the production capacity of the electric furnace, the total power used by the electric furnace is also increasing. However, when the existing electric furnace electrode clamp is running at high power, the contact point between the electrode and the clamp often overheats. Therefore, the existing cooling method usually uses water circulation for cooling, but this water cooling method is to wrap a coil around the outside of the clamp, with water entering one end of the coil and outgoing water at the other end. Due to the long coil path, the temperature of the cold water gradually increases after entering the coil from the water inlet. The cooling effect is worse for the coil as it goes back, and the lack of effective cooling leads to arc flash and fire at high temperatures, which not only damages the equipment, but also seriously affects production efficiency and safety. Utility Model Content
[0003] Based on this, the purpose of the utility model is to provide a novel electric furnace electrode clamp cooling device to solve the technical problems raised in the above background.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel electric furnace electrode clamp cooling device, comprising a water cooling component installed on the outside of the electric furnace motor clamp, the water cooling component comprising a plurality of water flow channel circulation groups, a water inlet pipe and a water outlet pipe, each of the water flow channel circulation groups is composed of three sealed water flow channels, the top of the first water flow channel is connected to the water inlet of the water inlet pipe, and the bottom of the first water flow channel is connected to the bottom of the second water flow channel, the top of the second water flow channel is connected to the top of the third water flow channel, and the bottom of the third water flow channel is connected to the water outlet of the water outlet pipe, the water inlet pipe surrounds the outside of the top of the plurality of water flow channel circulation groups and is away from the outer side of the electric furnace electrode clamp, and the water outlet pipe surrounds the outside of the bottom of the plurality of water flow channel circulation groups and is away from the outer side of the electric furnace electrode clamp.
[0005] Furthermore, one side of the water inlet pipe is connected to a water supply pipe, and one side of the water outlet pipe is connected to a drainage pipe.
[0006] Furthermore, the plurality of water flow channel circulation groups are welded from iron sheets.
[0007] The utility model adopts a water flow channel to water-cool the clamp, thereby increasing the contact area between the water flow channel and the clamp. In addition, the water inlet and outlet of each water flow circulation channel are independent, which reduces the cooling stroke of the cold water on the clamp, greatly improves the cooling effect, ensures its stable operation, and thus improves the overall performance and production efficiency of the electric furnace.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0012] The following describes an embodiment of the utility model based on its overall structure.
[0013] like Figure 1-Figure 3 As shown, the utility model includes a water-cooling component 2 installed on the outside of the electrode clamp 1 of the electric furnace, and the water-cooling component includes a plurality of water flow channel circulation groups 2, a water inlet pipe 3 and a water outlet pipe 4. Each water flow channel circulation group is composed of three sealed water flow channels. The top of the first water flow channel 21 is connected to the water inlet 31 of the water inlet pipe 3, and the bottom thereof is connected to the bottom of the second water flow channel 22. The top of the second water flow channel 22 is connected to the top of the third water flow channel 23, and the bottom of the third water flow channel 23 is connected to the water outlet 41 of the water outlet pipe 4. Preferably, the water flow channel circulation group 2 is welded from iron sheets, and the clamp is water-cooled by the water flow channel, which increases the contact surface between the water flow channel and the clamp. In addition, the water inlet and water discharge of each water flow circulation channel are independent, which reduces the cooling stroke of the clamp by cold water, greatly improves the cooling effect, ensures its stable operation, and thus improves the overall performance and production efficiency of the electric furnace.
[0014] One side of the water inlet pipe 3 is connected to a water supply pipe 5, and one side of the water outlet pipe 4 is connected to a drain pipe 6.

The water outlet pipe 4 surrounds the bottom outer side of the multiple water flow channel circulation groups 2 and is away from the outer side of the electric furnace electrode clamp 1. The water inlet pipe 2 and the water outlet pipe 4 are arranged away from the electric furnace electrode clamp 1, so that the water in the water inlet pipe 2 and the water outlet pipe 4 is not affected by the heat of the electric furnace electrode clamp 1, which greatly improves the cooling effect.
