Fig. 2 is the structural representation of another embodiment of the present invention.
Fig. 3 is the structural representation of body of the present invention.
Embodiment
As shown in Figure 1, the multi-functional deoxygenation dehydrogenator of oxygen free copper production of the present invention comprises:
Accommodating body 1, is made up of refined matte, has the accommodating cavity of hollow, has multiple dividing plate 11, is divided into multiple accommodation chamber;
Pressure column 3, is made up of refined matte, hollow and be shaped in accommodating cavity, and the circumference along pressure column is provided with multiple through hole;
The body 2 identical with number of openings, has bullet and depending post 4, and body in described through hole, contains deoxygenation dehydrogenating agent in bullet by depending post shrink-fit;
Lid, is made up of refined matte, is threaded with accommodating body; Described lid is provided with spiro union portion, and on described pressure column, correspondence is provided with screw thread, and when lid rotates according to a direction, while lid and accommodating body are spirally connected, pressure column and spiro union portion also cooperatively interact; On the lid that described spiro union portion is corresponding, be provided with at least two pores; Accommodation chamber between described body is built with deoxygenation dehydrogenating agent particle 5, and the component of deoxygenation dehydrogenation particle in different accommodation chamber is different.
When mounted, first by body dress in through-holes, the diameter of depending post slightly larger than the internal diameter of through hole, thus ensures to have good sealing effectiveness; Then in accommodating cavity, fill deoxygenation dehydrogenation composition.End cover, the most handy refined matte cast, is filled with nitrogen or rare gas from pore, sealing pore.When inflating, first opened by another pore, after estimating that the gas in accommodating body and pressure column is replaced, sealing cover pore, continues the pressure of punching to expection.
In a further embodiment, the accommodating cavity between body is built with deoxygenation dehydrogenating agent particle 5.Thus utilize accommodation space further, increase deoxygenation dehydrogenation effect.
In a further embodiment, described bullet from outside to inside, has the modular construction of some repetitions, and each modular construction comprises graphite linings 21, deoxygenation dehydrogenation oxidant layer 22 and refining layers of copper 23, and along direction from outside to inside, the thickness of repeat unit structure exponentially increases.After bullet is launched out, under powerful resistance, graphite linings comes off, deoxygenation dehydrogenating agent is evenly applied in copper liquid, and due in moving process, the surface-area of deoxygenation dehydrogenating agent is more and more less, in addition deoxygenation dehydrogenator place place also has other deoxygenation dehydrogenation compositions, so from its more away from place, the content of deoxygenation dehydrogenation composition is less, therefore will increase the thickness of internal layer deoxygenation dehydrogenation oxidant layer.
Be provided with clockwork spring in described through hole, described depending post is provided with the projection with clockwork spring adaptation.This projection is elastic bumps, inside establishes copper spring, and when depending post press-in through hole, spring contraction, after entering, spring struts, and coordinates with clockwork spring, and clockwork spring can make body obtain power along longitudinal axis rotation, thus increases its move distance in copper liquid.
When dropping into copper liquid, the outer field copper of deoxygenation dehydrogenator can melt, thus spill deoxygenation dehydrogenating agent input unit, due to the effect of clockwork spring and pressurized gas, body can be launched away, rotates simultaneously, thus ensures its segment distance that can move in molten steel, multiple unit is launched to different places, thus can deoxygenation dehydrogenating agent can rapid dispersion to everywhere.Simultaneously jet, before spray deaerator dehydrogenating agent throws in agent and in process, nitrogen or rare gas can be sprayed simultaneously, form bubble, cause the stirring of copper liquid, the chance that deoxygenation dehydrogenating agent throws in agent and molten steel or impurities impinge increases, thus improves deoxygenation dehydrogenating agent input efficiency.
In a further embodiment, described deoxygenation dehydrogenating agent be Calcium Fluoride (Fluorspan), rare earth and six calcium borides etc. weight mixture; Or, praseodymium, cerium and Calcium Fluoride (Fluorspan) etc. weight mixture; Be arranged at respectively in different accommodation chambers.Therefore, the deoxygenation dehydrogenating agent of different zones can be transported to different regions and carry out removal of impurities, and after starting magnetic stirrer, the composition between different zones can move along certain direction, further enhancing the effect of removal of impurities simultaneously.
In a further embodiment, from outside to inside, the component of the deoxygenation dehydrogenating agent in different deoxygenation dehydrogenation layer is different.Therefore, in the process of motion, different components is launched into different regions, thus enhances impurity-eliminating effect.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.
