Abstract
The utility model relates to a tube electric furnace used for reduction for cobalt powder, which comprises a hearth, a high temperature section and a cooling section, wherein the high temperature section is communicated with the cooling section; the high temperature section extends into the hearth; and the outer end of the high temperature section and the outer end of the cooling section are respectively provided with a material boat inlet and a material boat outlet. The tube electric furnace is structurally characterized in that the cooling section is internally provided with a fire stopping curtain; and the fire stopping curtain is formed by suspending temperature resistance fiber cloth pieces on the wall of the cooling section side by side. The tube electric furnace is adopted for realizing the reduction for the cobalt powder, thereby avoiding the detonation even the explosive accidents, being very safe and being suitable for the reduction in the production process of the cobalt powder.
Description
Technical field
The utility model relates to a kind of heating furnace.Specifically, be in the cobalt powder production process, to be used for electric tube furnace that cobalt powder is reduced.
Background technology
Know all that at the cobalt powder production industry electric furnace that is used for that cobalt powder is reduced all is an electric tube furnace.This electric tube furnace comprises burner hearth, high temperature section and cooling section, and high temperature section is connected with cooling section.High temperature section stretches in the burner hearth, and the outer end of high temperature section and the outer end of cooling section are left material boat inlet and the outlet of material boat respectively.End in the close high temperature section of cooling section is provided with hydrogen inlet.Cooling section wherein is a common pipe, does not have the fiery curtain of retaining in it.During work, when the material boat that cobalt powder to be restored is housed entered high temperature section from material boat porch, hydrogen fed and by discharging from material boat porch after the high temperature section from hydrogen inlet,, took out from the material boat outlet of cooling section after the cooling section cooling through the cobalt powder of reduction.Because cooling section is a common pipe, there is not the fiery curtain of retaining in it, when reduction finished to open discharge hole for discharge, airborne oxygen can enter cooling section by discharging opening, and hydrogen can be with higher pressure current to discharging opening one side.In a single day airborne oxygen contact with hydrogen and react, and can produce detonation even blast, very dangerous.
The utility model content
Problem to be solved in the utility model provides a kind of cobalt powder reduction electric tube furnace.Adopt this electric tube furnace that cobalt powder is reduced, can avoid detonation even explosion accident, as safe as a house.
For addressing the above problem, take following technical scheme:
Cobalt powder reduction of the present utility model contains burner hearth, high temperature section and cooling section with electric tube furnace, and high temperature section is connected with cooling section, and high temperature section stretches in the burner hearth, and the outer end of high temperature section and the outer end of cooling section have material boat inlet and the outlet of material boat respectively.Its design feature is that the fiery curtain of retaining is arranged in the cooling section, and this keeps off fiery curtain and is side by side shape by the temperature resistant fiber cloth and is suspended on the cooling section upper wall and forms.
The further improvement of the utility model scheme is that the fiery curtain of described retaining has twice.
Take such scheme, have the following advantages:
By such scheme as can be seen, owing in cooling section, be provided with the fiery curtain of retaining, when reduction finishes to open discharging opening, can stop hydrogen stream by keeping off fiery curtain, hydrogen stream is diminished to the pressure of discharging opening, the detonation even the blast that have prevented oxygen and hydrogen reaction from the air that exports into of material boat and produced, as safe as a house.
Description of drawings
Fig. 1 is a cobalt powder reduction electric tube furnace structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, cobalt powder of the present utility model reduction contains burner hearth 2, high temperature section 3 and cooling section 7 with electric tube furnace, and an end of high temperature section 3 and cooling section 7 is the sealing shape and links together, and makes the intracavity inter-connection of high temperature section 3 and cooling section 7.Be processed with reducing gas import 4 at cooling section 7 near on the end of burner hearth 2, so that when work, feed reducing gas.Reducing gas wherein is a hydrogen.Described high temperature section 3 stretches in the burner hearth 2, and the outer end of the outer end of high temperature section 3 and cooling section 7 is processed with material boat inlet 1 and material boat outlet 6 respectively, so that the material boat turnover of material is housed in the production process.For preventing to produce detonation even the generation of blast situation, in cooling section 7, be provided with twice and keep off fiery curtain 5 from material boat outlet 6 airborne oxygen of coming in and reducing gas (hydrogen) reaction.The fiery curtain 5 of described retaining is on the upper wall that shape side by side is suspended on cooling section 7 inner chambers by the temperature resistant fiber cloth and forms.
Claims (2)
