Description
Technical field
The present invention relates to the high-temperature smelting equipment field, be specially a kind of be used to blow smelt the graphite crucible structure of usefulness.
Background technology
In a lot of pyrolytic semlting technologies; Often have the behavior that feeds gas, these gases can be and smelt the gas that material reacts, also can be to be used for the inert gas that bubbling stirs homogeneous; Its adding mode can be top blast, side-blown and bottom blowing; For being lower than the side-blown and the bottom blowing of smelting the material liquid level, mode commonly used is in furnace chamber or crucible, to embed the air brick that high-temperature refractory is made, and adds to air brick outside furnace chamber or crucible that air pressure realizes.
Traditional air blowing mode has following obvious defects:
1, the necessary persistent pressure of air brick will be oozed out from air brick otherwise smelt material;
2, air brick is that the refractory material compacting forms, and meeting continues to consume in pyrolytic semlting, therefore must regularly replace;
3, air brick can be brought into and smelt in the material in consumption process, tends to pollute the smelting material.
4, the thermal coefficient of expansion of air brick and graphite crucible can not reach in full accord, occurs leaking the material phenomenon in the use easily.
To sum up can know; There is the inconsistent leakage material that causes of partial structurtes thermal coefficient of expansion in present air blowing smelting equipment; Exist local material to use inconsistent and bigger defectives such as secondary pollution that cause, special technology for the strict control of needs air brick contamination of raw material is all the more so.This case just produces thus.
Summary of the invention
The purpose of this invention is to provide a kind of air blowing that prevents Lou material and secondary pollution and smelt the graphite crucible structure of usefulness, and reach the effect that homogeneous is stirred in the gas liquid reaction when smelting of blowing, air-flow.
For realizing above-mentioned purpose, solution of the present invention is:
A kind of air blowing smelted the graphite crucible structure of usefulness, and it is provided with at least one gas channel in the crucible wall of graphite crucible, and the air inlet of this gas channel is provided in a side of on the outer wall of crucible, and at least one passage of gas channel is provided in a side of on the inwall of crucible.
