Abstract
The utility model discloses a melting pan for preparing lead-calcium-tin-aluminium alloy, comprising a pan body, a pan cover and a mixing shaft, wherein the pan body is provided with a semi-spherical internal chamber; the bottom of the pan body is provided with a material outlet; the pan cover is arranged on the pan body and is provided with a material inlet; the mixing shaft is arranged in the pan body and is driven by a power device; and the end part of the mixing shaft is provided with a mixing blade. The melting pan has reasonable structural design and dose not have dead corners during the preparing process of the alloy; furthermore, the mixing speed is quick, the mixing time is shortened, the oxidation and burning loss of the calcium during the alloy preparing process are lightened, the uniformity of the alloy composition is improved, and the production efficiency is improved.
Description
Technical field
The utility model relates to the lead acid accumulator plate grid technical field, is specifically related to a kind of preparation melting pan that is used for the Pb-Ca-Sn-Al alloy of grid material.
Background technology
Pb-Ca-Sn-Al alloy is widely used in the making of non-maintenance lead-acid accumulator grid and plumbous part, but the preparation of Pb-Ca-Sn-Al alloy has certain difficulty.The blending process of traditional Pb-Ca-Sn-Al alloy is: 1, add the lead pig in the alloy formula in smelting furnace (pot), be heated to 700 ℃, after treating that lead pig melts in the stove, add the aluminium ingot of aequum and aluminium ingot is pressed in the plumbous liquid, treat aluminium ingot fusing back stirring 5～10min, aluminium all is fused in the plumbous liquid equably.2, when plumbous aluminum alloy melt temperature in the stove during at 680 ℃～700 ℃, beginning is pressed into required calcium bits in plumbous liquid, stops to heat and the tin of adding aequum when waiting alloy temperature to drop to 500 ℃, and stirs 5～10min.3, the casting of alloy pig is carried out in descum then.
Because calcium is the active metal, the nucleidic mass of calcium is 40, and plumbous nucleidic mass is 207, so calcium is light than lead alloy, is difficult for being pressed into melting pan inside in process for preparation, and the oxidation of calcium and scaling loss are just more serious under hot environment, and calcium contents is wayward.Simultaneously owing to a large amount of oxidations and the scaling loss pollution on the environment of calcium in the Pb-Ca-Sn-Al alloy process for preparation are serious.The nucleidic mass of aluminium is 27, and in the alloy preparation process, same existence is pressed into the inner difficulty of melting pan, stirs uneven problem.All adopt the square melting pan at the general alloyage of battery industry, blast pressurized air and stir, in the process for preparation of alloy, because melting pan is a square, have the dead angle in the whipping process, in addition, pressurized air stirs insufficient homogeneity that can not guarantee alloy ingredient in the whole pot.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of preparation Pb-Ca-Sn-Al alloy melting pan is provided, its reasonable in design, in the alloy preparation process, stir no dead angle, and stirring velocity is fast, shortened churning time, alleviate the oxidation and the scaling loss of calcium in the alloy preparation process, improved the homogeneity of alloying constituent, improved production efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: preparation Pb-Ca-Sn-Al alloy melting pan, comprise a pot body, and described pot body has hemispheric inner chamber, is provided with discharge port in the bottom of described pot body; Be arranged at the pot cover on the described pot body, described pot cover is provided with opening for feed; Be arranged at described pot nside by the stir shaft that power set drives, be provided with agitating vane in the end of described stir shaft.
As a kind of optimized technical scheme, be surrounded with the pot edge at described pot body outer surface, be provided with the stiffening web of fixedlying connected with described pot body on top, described pot edge.
As a kind of optimized technical scheme, be provided with hanger in described pot external body, described hanger is provided with erection opening.
As a kind of optimized technical scheme, described hanger is provided with four, and described four hangers are distributed on the periphery of described pot body and the bottom is connected with described pot edge.
As a kind of optimized technical scheme, described pot cover is provided with to be hung.
After having adopted technique scheme, the beneficial effects of the utility model are: because pot body of the present utility model has hemispheric inner chamber, and in the pot body, be provided with the stir shaft that drives by power set, end at stir shaft is provided with agitating vane, adopt agitating vane that the intravital molten alloy composition of pot is stirred, so, the utility model efficiently solves traditional square melting pan and blasts the problem that there is the dead angle in the pressurized air stirring, can stir, and stirring velocity has shortened churning time soon, alleviate the oxidation and the scaling loss of calcium in the alloy preparation process, improved the homogeneity of alloying constituent, improved production efficiency.
