AI Technical Summary

Technical Problem

The existing induction furnaces have poor sealing at the exhaust port, which leads to leakage of chemical cleaning agents, endangering the health of operators and polluting the environment. At the same time, it reduces the sealing performance of the equipment and causes economic losses.

Method used

A sealing structure including a sealing ring and a cover plate was designed, combined with a motor-driven sealing rod and sealing ring, to ensure the upper and lower sealing of the water outlet tank. The cleaning agent is guided to the drain pipe through the sloping surface and the diversion channel, thereby improving the sealing performance of the furnace body.

Benefits of technology

It effectively prevents chemical cleaning agent leakage, protects the health of operators, reduces environmental pollution, improves equipment sealing, and avoids economic losses.

Abstract

This utility model relates to the field of metal material processing and treatment, and discloses a dual-purpose induction furnace for iron softening and zinc diffusion treatment, comprising: a furnace body; a top cover for sealing the furnace body, with a sealing rod fixedly connected to the bottom of the top cover; a bottom plate for the furnace body, with a base at the bottom of the bottom plate, a water outlet groove penetrating the bottom plate at the outermost side of the bottom plate, an annular sealing ring and a cover plate at the top of the water outlet groove, the sealing ring being located at the top of the cover plate, and an elastic element fixedly connected to the bottom of the cover plate; when the top cover is closed, the sealing rod contacts the sealing ring; an annular extrusion groove is formed at the bottom opening of the water outlet groove on the base, with a sealing ring fixedly connected to the top of the extrusion groove. In this utility model, the sealing ring and cover plate at the top of the water outlet groove and the sealing ring at the bottom of the water outlet groove simultaneously seal the water outlet groove, creating a sealing effect on both the upper and lower sides of the water outlet groove, improving the sealing performance of the furnace body and avoiding problems caused by poor sealing of the discharge port.
