Description

Technical Field

[0001] The present application relates to the technical field of waste slag and waste material recycling, and in particular to a lead-silver slag recycling proportioning device. Background Art

[0002] Lead-silver slag is decomposed and oxidized at high temperature in an oxygen-enriched bottom-blowing furnace, so that zinc exists in the form of oxide, lead and silver exist in the form of oxides and elements, and sulfur enters the flue gas in the form of sulfur dioxide. The liquid high-lead slag is reduced again in the oxygen side-blowing metal molten reduction furnace, and lead and silver are reduced to elements. Lead serves as a good collector for silver, and silver is enriched in the crude lead produced by the reduction furnace. After a large proportion of lead-silver slag is added, the sulfur content of the mixture entering the bottom-blowing furnace is reduced, which cannot guarantee self-heating smelting. The reduced sulfur dioxide concentration in the flue gas is also not conducive to the production of sulfuric acid from the flue gas later in the process.

[0003] To this end, we propose a lead-silver slag recovery and proportioning device, which is convenient for proportioning lead-silver slag with one or more of lead sulfide concentrate, lead-containing materials, iron ore, limestone, quartz sand, pyrite, and coal, so that the mixed material meets the production grade requirements, and then after granulation, it is oxidized and smelted in an oxygen-enriched bottom blowing furnace to improve the production quality and production efficiency of smelting.

[0006] The mixing mechanism includes a driving motor, a driving rod, a breaking up assembly, a mixing assembly and a dividing assembly. The driving motor is fixedly arranged on the top of the cylinder. One end of the driving rod is rotatably installed on the top of the cylinder, and the other end of the driving rod is located in the cylinder. The breaking up assembly, the mixing assembly and the dividing assembly are fixedly arranged on the driving rod in sequence from top to bottom.

[0028] The embodiment of the present application discloses a lead-silver slag recovery and proportioning device.

[0029] Reference Figure 1-3 A lead-silver slag recovery and proportioning device comprises a cylinder 1, a plurality of proportioning pipes 11, an air inlet pipe 12 and a mixing mechanism 2, wherein the plurality of proportioning pipes 11 are circumferentially arranged on the side wall of the cylinder 1, the air inlet pipe 12 is connected and arranged on the top of the cylinder 1, and the mixing mechanism 2 is arranged in the middle of the cylinder 1;

[0030] When in use, a variety of ingredients enter the barrel 1 from the ingredient pipe 11 at the same time, are broken up, mixed, and evenly discharged into the bottom blowing furnace through the mixing mechanism 2, which can effectively make the ingredients fully react with the lead and silver slag, greatly improving the quality and efficiency of smelting.

[0031] Reference Figure 2-3 The mixing mechanism 2 includes a driving motor 21, a driving rod 22, a breaking component 23, a mixing component 24 and a material dividing component 25. The driving motor 21 is fixedly arranged on the top of the cylinder 1. One end of the driving rod 22 is rotatably mounted on the top of the cylinder 1. The other end of the driving rod 22 is located in the cylinder 1. The breaking component 23, the mixing component 24 and the material dividing component 25 are fixedly arranged on the driving rod 22 from top to bottom in sequence.

[0032] When in use, the driving motor 21 drives the driving rod 22 to rotate, driving the breaking component 23, the mixing component 24 and the dividing component 25 to rotate simultaneously, which can effectively break up, mix and evenly divide the ingredients entering the barrel 1 from the ingredient pipe 11 in turn, so that the ingredients can react more efficiently after being discharged into the bottom blowing furnace.

[0033] Reference Figure 2-3 The scattering assembly 23 includes a plurality of scattering rollers 231, which are circumferentially fixedly arranged on the driving rod 22.

[0036] When in use, the mixing disk 241 rotates in the cylinder 1 driven by the driving rod 22, and the various ingredients fall onto the mixing disk 241 after being scattered by the scattering component 23. The various ingredients are mixed under the continuous collision of the mixing plate 243. At the same time, when the materials collide and mix, they continuously fall from a high place to the middle of the mixing disk 241, and fall from the through hole 244 in the middle to the dividing component 25, which can effectively mix the various ingredients.
