1. A system for smelting tin-containing materials, comprising a pretreatment mechanism, a screening mechanism, a feeding mechanism, a smelting mechanism, a slag treatment mechanism and a tail gas treatment mechanism;
the screening mechanism comprises a screening machine, a fine material silo and a coarse material silo;
an upstream of the screening machine is connected with a downstream of the pretreatment mechanism, an upper-screen material outlet of the screening machine is connected with the coarse material silo, an under-screen material outlet of the screening machine is connected with the fine material silo, and the coarse material silo and the fine material silo are respectively connected with the smelting mechanism through the feeding mechanism;
the feed mechanism comprises a feeding device, a batching bin, a first front bin, a second front bin, a spray gun and a pulverized coal bin;
the coarse material silo is communicated with the batching bin through the feeding device, and the batching bin is communicated with the smelting mechanism through the feeding device;
an upstream of the first front bin is communicated with the fine material silo, and a downstream of the first front bin is communicated with the smelting mechanism through the spray gun;
an upstream of the second front bin is communicated with the slag treatment mechanism, and the tail gas treatment mechanism is downstream of the second front bin and is communicated with the smelting mechanism through the spray gun;
wherein the pulverized coal bin communicated with the smelting mechanism through the spray gun.
