AI Technical Summary

Technical Problem

The side-blown furnace feeding system is prone to blockage by lumps of material, leading to clogging and slagging, which affects production efficiency and safety. Conventional solutions are slow to respond and inefficient.

Method used

The system employs a feeding hopper, weighing alarm components, and a horn-shaped furnace top cover feeding port structure, combined with an annular gap channel and dredging port design, to achieve early warning and timely cessation of feeding, reduce material contact with the inner wall, and prevent adhesion and slag formation.

Benefits of technology

It effectively prevents material blockage at the feed inlet, shortens the time for clearing blockages, improves production efficiency and safety, maintains stable negative pressure inside the furnace, and reduces flue gas escape.

Abstract

This utility model discloses a side-blown furnace feeding structure, including a feeding hopper, a weighing alarm component, a feeding port vertical pipe, and a furnace top cover horn-shaped feeding port. The feeding hopper vertical pipe is coaxially inserted into the feeding port vertical pipe to form an annular gap channel. The weighing alarm component includes a weighing sensor fixed to the outer wall of the feeding hopper, an alarm device electrically connected to the sensor, and an interlocking stop feeding execution mechanism. When the feeding hopper accumulates material due to blockage, the weighing sensor monitors the weight change in real time and triggers the alarm device, simultaneously stopping the feeding. The horn-shaped opening of the furnace top cover feeding port faces the furnace chamber, reducing the contact between the material and the inner wall, reducing adhesion and slag formation. The annular gap channel forms an air guiding cavity, maintaining stable negative pressure inside the furnace, preventing flue gas from escaping, and improving smelting safety and efficiency.
