Embodiment Construction

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] Such as figure 1 As shown, a safe fuming furnace includes a furnace tube 1, a flue 2 and a dust collection device 3, one end of the flue 2 communicates with the upper part of the furnace tube 1, and the other end of the flue 2 communicates with the upper part of the furnace tube 1. The dust collecting device 3 is connected;

[0021] The furnace drum 1 includes a furnace drum body 11 , a feeding tank 12 , an air inlet 13 and a slag cleaning port 14 , and the feeding tank 12 is placed on one side of the furnace drum body 11 and below the flue 2 , the air inlet 13 and the slag removal port 14 are sequentially arranged on the other side of the furnace body 11 from top to bottom;

[0022] The flue 2 includes a f...

Abstract

The invention relates to a safe fuming furnace. The safe fuming furnace comprises a drum, a flue and a dust collecting device, wherein one end of the flue communicates with the upper part of the drum;the other end of the flue communicates with the dust collecting device; the drum comprises a drum body, a feed tank, an air inlet and a slag cleaning opening; the feed tank is placed on one side of the drum body; the air inlet and the slag cleaning opening are successively arranged on the other side of the drum body from top to bottom; the flue comprises a flue body and collecting hoppers; the collecting hoppers are rotatably placed at the lower end of the flue body and communicates with the flue body; rotatable fan blades are arranged in the flue body; an electromagnetic heater is arranged on one side of each collecting hopper; and each electromagnetic heater is connected with a power supply through a time relay. Compared with the prior art, the safe fuming furnace has the advantages that the collecting hoppers of the flue can be heated under the condition that the flue is blocked, thus, blocking substances are softened and flow downwards, then the flue is smooth, the production efficiency is improved, and the dangers of industrial injury accidents and occupational diseases due to the fact that workers enter the flue to dredge are avoided.

Description

technical field [0001] The invention relates to the technical field of mineral smelting, in particular to a safe fuming furnace. 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 Scrap Metal and Tin in Tin-Containing Materials", the flue and collecting hopper of this patented equipment are often blocked, so that every certain It is necessary to stop the furnace for a while, let the temperature drop, and then let the workers go in to clean the flue, empty the blocked flue again, and then restart the furnace, because most of the materials that block the flue are molten large particles of slag , in the...
