Abstract

The invention relates to a fuming furnace capable of achieving preheating and recycling. The fuming furnace comprises a furnace barrel, a flue and a dust collecting device. One end of the flue is communicated with the upper portion of the furnace barrel, and the other end of the flue is communicated with the dust collecting device. A filtering screen is arranged at the communication part of the flue and the dust collecting device. The furnace barrel comprises a furnace barrel body, a feed tank, an air inlet and a residue removing port, wherein the feed tank is arranged on one side of the furnace barrel body and located below the flue, and the air inlet and the residue removing port are formed in the other side of the furnace barrel body from top to bottom in sequence. The flue comprises a flue body and a collecting hopper, wherein the collecting hopper is arranged at the lower end of the flue body in a self-revolving mode and is located above the feed tank. The lower portion of the dust collecting device is communicated with the feed tank through a heat transmitting pipe, and a fan blowing air to the feed tank is arranged in the heat transmitting pipe. Compared with the prior art, waste heat in the dust collecting device can be recycled, mineral materials in the feed tank can be preheated, energy consumption can be reduced, and the fuming efficiency can be high.

Description

technical field [0001] The invention relates to the technical field of mineral smelting, in particular to a fuming furnace for preheating recovery. Background technique [0002] As we all know, the fuming furnace is a kind of pyrometallurgical equipment that reduces and volatilizes non-ferrous metals such as lead, zinc, tin, and indium at high temperatures, and then oxidizes or sulfides them into soot, which is enriched in the soot for further recovery. The existing fuming furnace equipment, the application number is 201220015549.4 "Fuming Furnace for Efficiently Recycling Tin in Scrap Metal and Tin-Containing Materials", this patented equipment cannot carry out waste heat recycling, serious energy waste, and low fuming efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of preheating recovery fuming device that can recycle the waste heat in the dust collecting device and preheat the ore in the fee...
