AI Technical Summary

Technical Problem

In the fuming furnace process, a large amount of dust is generated during the feeding and transportation of tin concentrate particles, leading to environmental pollution and health risks, and it is difficult to effectively control secondary dust.

Method used

A fuming furnace with dust-free feeding is designed. First and second dust removal mechanisms are used to perform layered dust removal in the feeding and conveying processes, respectively. The first dust removal mechanism is set above the feeding hopper of the fuming furnace and the second dust removal mechanism is set inside the conveying box. Dust is captured and filtered by a dust collection fan and dust collection bags, and valve control is combined to ensure that dust does not leak out.

Benefits of technology

It effectively controlled dust leakage during the feeding and conveying of tin concentrate particles, improved dust collection efficiency, and enhanced operational safety and production efficiency.

Abstract

This utility model discloses a fuming furnace with dust-free feeding, belonging to the technical field of flue gas treatment equipment. It includes a fuming furnace feeding hopper, an intermediate hopper connected to a discharge pipe via a feeding pipe, a first dust removal mechanism above the feeding hopper, and a conveying box connected below the discharge pipe. A conveying mechanism is installed inside the conveying box, and a second dust removal mechanism is installed on the conveying mechanism. During the conveying process, the disturbance of powder may cause residual dust to be released. At this time, the second dust removal mechanism performs secondary dust removal. After the powder is conveyed to the end of the conveying box, it is introduced into the next production step through the outer feeding port. This achieves most of the dust removal during the feeding and conveying process, effectively controls dust leakage, and has high dust collection efficiency.
