Abstract
The utility model relates to a kind of furnace of calcium carbide blanking column, comprise supporting base and tremie pipe, described supporting base is through casting integrated shaping, be positioned at the top of described tremie pipe, it is characterized in that, described tremie pipe is interior outer double-layer structure, skin is made up of ceramic material, the blanking column that the utility model provides can not only effectively avoid blanking column to leak the danger caused, and also has certain ductile strength, and cost is lower.
Description
Technical field
The utility model relates to a kind of blanking column, blanking column in the stove particularly relating to a kind of furnace of calcium carbide.
Background technology
In the stove of furnace of calcium carbide, blanking column at high temperature uses, and contacts to some extent with high temperature charge level.In order to increase its service life, traditional blanking column adopts water-cooling structure, but due to thermal stress comparatively large, causing impact of leaking produce and even injury accident occurs.
Blanking mouth in the stove that Chinese utility model patent ZL200820190502.5 discloses a kind of mineral hot furnace, namely use silicon nitride and carbofrax material once sintered shaping, without the need to logical water quench, avoid setting off an explosion dangerous because logical cooling water leaks and reducing heating blowing-out, thus improve service life and equipment operation rate, but in the operation of furnace of calcium carbide, often there is the situation that charge level hardens, need manually to disclose material.The blanking column fragility of silicon nitride and silicon carbide material is very large, easily breakage occurs during ramming.And the cost of the blanking column of this kind of material is higher.Furnace of calcium carbide operationally, is weak oxide atmosphere in stove, the easy oxidized scaling loss of carborundum.
Utility model content
The utility model, for the deficiency in existing blanking column use procedure, provides a kind of novel furnace of calcium carbide blanking column.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of furnace of calcium carbide blanking column, comprise supporting base and tremie pipe, described supporting base, through casting integrated shaping, be positioned at the top of described tremie pipe, it is characterized in that, described tremie pipe is interior outer double-layer structure, and skin is made up of ceramic material.
The beneficial effects of the utility model are:
The blanking column that the utility model provides can not only effectively avoid blanking column to leak the danger caused, and also has certain ductile strength, and cost is lower.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described ceramic material is selected from MgO, Al

In Fig. 1 and Fig. 2,1, supporting base; 2, tremie pipe; 3, tremie pipe is outer
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with example, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As depicted in figs. 1 and 2, a kind of furnace of calcium carbide blanking column, comprises supporting base 1 and tremie pipe 2, described supporting base 1, through casting integrated shaping, is positioned at the top of tremie pipe 2, and tremie pipe 2 is interior outer double-layer structure, supporting base 1 is made by stainless steel with the internal layer of tremie pipe 2, and the skin 3 of tremie pipe 2 is by Al
2o
3make.
When making above-mentioned furnace of calcium carbide blanking column, first casting blanking column supporting base 1, is welded on supporting base 1 by tremie pipe 2 afterwards, connects silk screen, by Al in tremie pipe 2 outside
2o
3coating overlays on the outside of tremie pipe, afterwards 800 DEG C of high temperature sinterings 2 hours, and obtained described furnace of calcium carbide blanking column.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
