A kind of mixer
Technical field
The present invention relates to a kind of mixer, especially a kind of horizontal mixer.
Background technology
In industrial production, often can relate to a kind of metal or alloy of melting, make the technique of itself and another kind of corrupt split or attachment.All can be oxidized because most metal contacts with oxygen, as at static tin stove or scruff (SnO and SnO that dynamically produce in Wave soldering furnace
2) be namely the modal example of burning in a kind of industry.In high temperature environments, especially under melting state, the situation that metal (or alloy) is oxidized can be more violent, can form one deck oxide very soon, and more poly-more.And adhering in the technical process combined at motlten metal and other metals, motlten metal must ceaselessly flow circuit, and this can aggravate oxidation rate on the one hand, means that the oxide on top layer and a small amount of oxygen can be brought to below liquid level, i.e. liquid internal on the other hand.So be oxidized and can occur equally in inside.Such oxide, by carrying the floating upper liquid level of good metal secretly, forms scum silica frost.Because scum silica frost ceaselessly produces, emersion, causes scum silica frost to accumulate more and more, is stacked layer by layer, more and more thicker, affects liquid level flowing, even produce excessive after several hours, pollutes again dangerous.The scum silica frost produced normally can not participate in the production process merged, and can only constantly salvage out, otherwise processed.After salvaging scum silica frost, liquid level is inadequate, even produces consumption inadequate, ceaselessly can only add supplementary new raw metal.
If the scruff residue that stanniferous amount is high is not utilized by throwing away, waste can be caused.The method of adding reducing agent is adopted to reduce to scruff in prior art, but need in reduction process to stir, at present in practice process, what adopt is pinion rotation formula mixer, but this type of mixer is in whipping process, solder and reacted purees can enter in gear-box blocks gear, and cause mixer cisco unity malfunction, life cycle is very short.

The use procedure of above-mentioned mixer is as follows:
This mixer is set up on weldpool sidewall, the first support 41 and the second support 44 is made to be individually fixed on the relative sidewall of weldpool two, and the first limiting plate 42 and the second limiting plate 45 are positioned at the outside of two side, make mixing component, transmission component, deflector 5, collection assembly be positioned at weldpool.
The position of fine setting mixer, makes driving wheel 26 and driven pulley 27 immerse in fusion welding, and in weldpool the liquid level of fusion welding higher than the engaging piece of driving wheel 26 and driven pulley 27, lower than the minimum point of output shaft 24 with transmission case 21 junction.(for making fusion welding liquid level higher than the engaging piece of driving wheel 26 with driven pulley 27, lower than the minimum point of output shaft 24 with transmission case 21 junction, driven pulley 27 below being at least major part is immersed in fusion welding, and the driving wheel 26 being in top has fraction to immerse in fusion welding, be appreciated that, when driving wheel 26 is in directly over driven pulley 27, driven pulley 27 immerses in fusion welding completely, and driving wheel 26 has fraction to be immersed in fusion welding.) and make liquid level be positioned at the lower edge in slag-overflowing plate 81 bottom slag input hole 811.Starter motor body 11, motor body 11 drive motors rotating shaft 12 is rotated, thus drive output shaft 24 to rotate, and then fixing main shaft 31 rotates with output shaft 24, and, the driving wheel 26 that the rotating drive of output shaft 24 is fixed on output shaft 24 rotates, the driven pulley 27 engaged with driving wheel 26 produces and rotates, then the driven pulley fixed axis 29 be fixedly connected with driven pulley 27 rotates, the rotation of the secondary shaft 32 that the rotation drive of driven pulley fixed axis 29 is fixedly connected with driven pulley fixed axis 29, now, main shaft 31 and secondary shaft 32 all rotate, thus the stirring vane 33 be fixed on main shaft 31 and secondary shaft 32 is rotated, driving fusion welding flows.
By above-mentioned mixer, make the liquid level of fusion welding in weldpool higher than the engaging piece of driving wheel 26 and driven pulley 27, lower than the minimum point of output shaft 24 with transmission case 21 junction.On the one hand, make the engaging piece of driving wheel 26 and driven pulley 27 be immersed in fusion welding, driving wheel 26 and driven pulley 27 can be avoided to be stuck in rotation process, raise the efficiency.Simultaneously, main driving wheel 22 and auxiliary driving wheel 23 are positioned at closed transmission case 21, and the liquid level of fusion welding is positioned under the minimum point of output shaft 24 and transmission case 21 junction, cannot enter transmission case 21, that is, main driving wheel 22 and auxiliary driving wheel 23 there will not be stuck phenomenon.On the other hand, this mixer effectively can be collected scum silica frost.
According to the present invention, when above-mentioned mixer is in weldpool, when using with reducing agent simultaneously, the bulk scum silica frost of formation can be broken up, reduce by reducing agent, and form fritter scum silica frost, fritter scum silica frost is under the driving of mixer, to collection assembly flowing, by slag input hole 811, enter the collecting region of collection assembly.And bulk scum silica frost (inner containing tin material) can be stopped by slag input hole 811, still stay in weldpool, be reduced agent reduction.Now, collection assembly can be avoided collecting not reducing scum silica frost completely, improves the utilization rate of tin material, and the scum silica frost simultaneously collected in collection assembly is assembled in collecting region, again can not spread apart, improve the efficiency of collection.When needs are except removing dross, directly by handle 92, filter 91 taken out, scum silica frost can be removed.Easy to operate.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
