AI Technical Summary

Technical Problem

In a vacuum smelting furnace, high-temperature melts tend to adhere to the inner wall of the feed pipe, resulting in poor material flow, slowing down discharge speed and uneven feeding, affecting the stability of the smelting process and product quality.

Method used

A high-temperature melt feeding device for vacuum melting furnaces is designed, using an inclined feeding pipe and anti-blocking mechanism, including a push column and a driving mechanism, which reduces melt adhesion through gravity and dynamic cleaning mechanisms to ensure smooth flow of materials.

Benefits of technology

Through the design of the inclined feed pipe and anti-blocking mechanism, the adhesion of the melt on the pipe wall is effectively reduced, the discharge speed and feeding efficiency are improved, and the stability of the smelting process and product quality are ensured.

Abstract

The high-temperature melt feeding device comprises a base and a smelting furnace body arranged above the base, a feeding hopper is connected to the upper portion of the smelting furnace body, the side wall of the smelting furnace body is communicated with a feeding pipe, and the feeding pipe is obliquely and downwards distributed in the direction from the outer side to the inner side of the smelting furnace body. The feeding pipe is communicated with the feeding hopper, an anti-blocking mechanism is further arranged in the feeding pipe, and the anti-blocking mechanism comprises a pushing column arranged in the feeding pipe and a driving mechanism used for driving the pushing column to axially slide along the inner wall of the feeding pipe. The feeding pipe which is obliquely arranged is connected with the smelting furnace body, melt materials are added into the smelting furnace body through gravity, the anti-blocking mechanism is arranged in the feeding pipe, the situation that the melt materials are prone to being attached to the pipe wall in the feeding process is effectively reduced, the feeding efficiency is improved, and the frequency of shutdown cleaning is reduced.
