FURNACE FOR WQRKING Z AND LEAD.
SPECIFICATION forming as. of Letters Patent No. 605,802, dated June 14, 1898. Application filed March 18, 1897. Serial No. 628,213. (No model.)
To all whom it may concern:
Be itknownthat'I, RICHARD S HNEIDER, civil engineer,a subject of the King of Saxony, residing at Dresden, in the Kingdom of Sax ony, German Empire, have invented new and useful Improvements in Furnaces for Working Zinc and Lead, of which the following is a specification.
My invention relates to improvements in furnaces for working zinc ofi its ores, and especially such ores'as contain a considerable quantity of lead; and its object is to produce the zinc and lead simultaneously Without thereby injuring the retorts, so that in the furnaces which form the subject of this invention ores can be worked which for the destructive influences on the retorts of the lead they contain cannot be treated inthe furnaces that are at present in use.
The improvements consist mainly in the particular arrangement of separate receivers illustrated in the accompanying drawings for collecting the vapors of zinc developed in the retort and of the lead which smelts from the ore.
The drawings represent, in Figure 1, a vertical section of the entire furnace, taken through line 1 l in Fig. 2; Fig. 2, a horizontal section of the same, following the line 22 in Fig. 1; Fig. 3, a cross-section taken through line 3 3 in Fig. 1. Fig. asho'ws the upper receiving vessel or condenser adjoining the re tort, drawn on a larger scale. Figs. 5 and 6 are sections through a retort, showing the position therein of the extremities of the up per and the lower receiver.
Similar letters refer to similar parts throughout the several views.
- The general arrangement of the furnace does not differ essentially from that of the furnacesin use, as the retorts a are arranged in series in one or two chambers b b and subjected to a suitable heating, as required by the process. This heatingv may be effected, by way'of example, by means of a regenerative gas-furnace, vthe gas and air regenerators being indicated in the drawings by the letters of reference c'and d, and the gas-burner. by the'letter c. This gas-furnace with regenerators being known to all those skilled in the art, no further explanation thereof is required. I
other side.
As clearly shown by Figs. 2 and 8, the retorts a, of the furnace, instead of being open only on one side, as usual, are open on both sides. From the-upper side of each retort, which with preference is situated in an inclined position, there projects in a well-known manner the receiver 2 for the vapors of zinc developed in the retort, the receiver having the purpose of condensing said Vapors and of collectingthe metallic zinc. In combination with this receiver a tubular extension g, as customary, may be provided for in such a way as to be easily removed, if required. At the other and lower end of each retort another receiver f is arranged, tightly closed at its outer end, so as to prevent the atmospheric air from entering. This has the purpose to collect the metallic lead which smelts from the charge contained in the retort.
Both the receivers are provided with a trough e and f on their soles to facilitate the the ore treated in the retorts will pass over into the upper receiver e and condense there, with the effect of forming metallic Zinc, while the lead separated at the same time from the ore in consequence of its greater specific gravity will flow downward, enter the lower receiver f, and collect in the trough f. The process being finished, the metallic zinc may be taken from the upper receiver and the metalliclead from the lower receiver.
The merits of an arrangement substantially as here specified consist in the possibility not only of working zinc and lead out of its ores simultaneously, but also of collecting the liquid lead not in the hot retort, but in a cooler receiver, which has onlya temperature sufficient to keep the lead in molten state, so asto permit the single drops of leadto flow down into the trough. The lead being drawn from the retorts immediately after its separation from the heated ore cannot, as in the furnaces which are at present in use, destroy the walls of the retorts, such destruction being generally the cause of great losses in zinc and in lead.
What I claim as my invention, and desire The vapors of zinc rising from ceiverf for the liquid lead, and of troughs e, f on the soles of said receivers for simultaneously collecting one the metallic zinc and 15 the other the metallic lead; substantially as and for the purpose set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
