The invention discloses a zinc metallurgy device and a zinc metallurgy technique. The zinc metallurgy device comprises a smelter hearth for melting zinc concentrate to smelt for ingoting; a blast furnace for melting the ingoting to lead zinc in the ingoting to become zinc vapor; and a condensation separating device, a stock gas inlet of which is connected with a stock outlet of the blast furnace;the condensation separating device accommodates liquid lead and receives zinc-containing stock gas from the blast furnace and captures zinc from the zinc-containing stock gas by the liquid lead as wellas leads the captured zinc to become liquid zinc floating above the liquid lead for separating lead and zinc. The zinc metallurgy device and zinc metallurgy technique provided by the invention reduce air and noise pollution, improve efficiency, reduce cost and investment, and effectively use resources and energy.

The invention belongs to the technical field of slag reutilization and particularly relates to a process for reusing slag of an aluminum smelting furnace. The process adopts the smelting furnace. Thesmelting furnace comprises a box body and further comprises a crushing unit, material guide units, a smelting chamber, a motor, a collecting box, a first pipe, a purifying unit and a controller. By the adoption of the process, on the one hand, in the process of mixing the aluminum slag and an aqueous solution of a sintering machine, the aluminum slag and the aqueous solution of the sintering machine are fully mixed to form blanks while being added and stirred; meanwhile, spray nozzles are used to spray water mist to the blanks during the pressurization and plasticity of the blanks, so that theblanks are tightly attached, no fracture occurs between the blanks during sintering in the sintering furnace, and thus the quality of a refractory blank is improved; and on the other hand, the formedrefractory blank is installed on the inner wall of the smelting chamber to prevent the smelting furnace from being damaged when aluminum metal is smelted, so that the service life of the smelting chamber is prolonged.

The invention relates to a composite fuel fuming furnace reduction and volatilization smelting method and belongs to the technical field of thermometallurgy. The method comprises the steps that pulverized coal and natural gas are adopted as a composite fuel of reduction and volatilization smelting of a fuming furnace, the natural gas is sprayed into the fuming furnace through natural gas spray nozzles, the pulverized coal and primary air are blended in a pulverized coal fuel supply system and then sprayed into the fuming furnace through pulverized coal spray nozzles; and in the reduction and volatilization smelting process, the pulverized coal spray amount and the natural gas spray amount are regulated according to the situation of cold and hot materials of the fuming furnace. By adoptingthe reduction and volatilization smelting method, the temperature rising speed is high, the fuming furnace is flexible to operate, regulation is easy and convenient, the automation degree is high, andthe problems that supply of the pulverized coal or the fuel gas is interrupted and consequentially slag discharging of the fuming furnace is difficult can be effectively prevented; clean and long-period continuous production and operation can be achieved, reduction and volatilization reaction of the fuming furnace is more thorough, and matching with an upstream and downstream operation system isfacilitated; and the production efficiency is high, production control is stable, and stable and refined production control can be achieved easily.

The invention discloses bottom-blowing smelting equipment, which comprises a furnace body. A material inlet and a flue gas outlet are arranged at the upper part of the furnace body. A product outlet and a slag outlet are arranged on the side part of the furnace body. A vulcanizing agent steam passage and a reaction gas passage are arranged at the bottom of the furnace body to respectively feed vulcanizing agent and reaction gas into the furnace body. The bottom-blowing smelting equipment provided by the embodiment of the invention has the advantages that since the reaction materials are added into the furnace body from the top of the furnace body and the reaction gas and the vulcanizing agent are fed into the furnace body from the bottom of the furnace body, the reaction materials can be agitated, the smelting reaction is enabled to be more full and the consumption of energy for reaction is reduced.

The invention discloses an aluminum-iron separation device for automatic melting of recycled aluminum and relates to the technical field of recycled aluminum smelting. The invention includes a smelting and separating furnace and a separating device, wherein a stirring motor is installed on the surface of the smelting and separating furnace, and an electric heating block is installed inside. In the present invention, by setting a smelting separation furnace and a separation device, and connecting the two with each other, the waste aluminum material is automatically melted and separated from iron impurities, and through two-stage separation, it is beneficial to the purification of recycled aluminum and improves the separation efficiency; by setting a stirring motor , the smelting and separation furnace can fully smelt the waste aluminum by using the stirring effect; at the same time, by setting the filter hole, it is convenient to separate the completely smelted aluminum liquid from the iron impurities, and flow into the auxiliary separation box along the separation channel for the next step One-step separation process; by setting up an auxiliary separation box, using the method of injecting coolant and electrolyte into the box, the aluminum liquid is rapidly cooled and condensed into a solid, and then the electrolyte is used to separate trace impurities on the surface to complete the separation.
