[0003] By analyzing the internal flow direction of the cooling water of the cooling device at the lower part of the resistance furnace, it is found that there are several dead zones in the process of water flow, and the air bubbles in the water rarely flow or flow slowly in these places, so the stainless steel plate on the upper plane of the cooling device is under pressure. When there is high heat radiation, there will be carbon precipitation due to insufficient cooling, and then water leakage will occur

Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, the cooling device for a high temperature environment according to the present invention includes: an inner body 1, an outer body 2, a deflector 3, a water inlet 4, a bubble collection tank 5 and a water outlet 6,
[0018] The inner body 1 is set in the supporting outer body 2, the two are welded together, the inner body 1 directly bears the heat radiation, especially the upper plane of the inner body is close to the heat radiation area (the upper plane of the inner body is used to carry the resistance furnace ), the heat radiation is the strongest,
[0019] Below the upper plane of the inner body, the outer body 2 is provided with a deflector 3 that guides the direction of the water flow. A bubble collection tank 5 is arranged between the outer body 2 and the deflector 3. Under the guidance, it runs close to the inner surf...

The invention relates to a cooling device of an electric resistance furnace, and specifically relates to a cooling device used in hot environment. The cooling device is characterized in that an inner body (1) is sleeved in an outer body (2) used for playing a support action, the inner body (1) and the outer body (2) are welded together, the inner body (1) directly receives heat radiation, and the upper part flat surface of the inner body is used for bearing the electric resistance furnace; a guide plate (3) is arranged in the outer body (2) and is positioned below the upper part plane of the inner body and has a flow direction guidance action, and a bubble collecting groove (5) is arranged between the outer body (2) and a guide plate (3); and waterflow pastes the inner side face of the upper part plane of the inner body to operate under the guidance of the guide plate (3), the bubbles in the water are brought into the bubble collecting groove (5), the bubble collecting groove (5) is communicated with a water outlet (6), and the lower part of the outer body (2) is provided with a water inlet (4). The cooling device used in hot environment provided by the invention has the advantages that the service life is long, and the cooling device can carry out long-term stable operation under high power and high temperature of the electric resistance furnace and cannot leak water.
Description
technical field [0001] The invention relates to a cooling device for a resistance furnace, in particular to a cooling device used in a high-temperature environment. Especially the cooling device used in the high temperature environment of the electric resistance furnace. Background technique [0002] As the heating power of the resistance furnace is getting higher and higher, the upper plane of the cooling device at the lower part of the furnace is subject to increased direct heat radiation, resulting in carbon deposition on the stainless steel on the upper plane. There are many micropores on the heat radiation surface, which leads to water leakage accidents and seriously affects the stable production. With the increase of the power of the resistance furnace, the working environment of the cooling device at high temperature is getting worse, and the time for water leakage is shorter, which plagues the normal production. [0003] By analyzing the internal flow direction of ...
