Reduction furnace

Abstract

The invention discloses a reduction furnace. The reduction furnace comprises a heating furnace, a reduction tank and a hanging-type weighing device, wherein the heating furnace is provided with a hearth capable of being opened and closed; and the hanging-type weighing device is fixedly arranged above the hearth and used for hanging the reduction tank in the hearth. The reduction furnace further comprises a tank loading-unloading device used for moving the reduction tank into the hearth and hanging the reduction tank onto the hanging-type weighing device, and taking down the reduction tank fromthe hanging-type weighing device and moving the reduction tank out of the hearth. The reduction furnace has the advantages of being long in service life, high in treatment efficiency, high in weighing stability and accuracy, convenient to overhaul and maintain, and the like.

Description

technical field [0001] The invention relates to the technical field of heat treatment furnaces, in particular to a reduction furnace. Background technique [0002] The existing reduction furnace mainly includes a heating furnace, a cylindrical reduction tank, and a weighing balance. The upper part of the hearth of the heating furnace has an inlet and outlet for the reduction tank to pass through. The weighing balance is installed on the lifting end of the lifting device. In the reduction tank, hang the reduction tank on the weighing balance, and then hoist the reduction tank through the hoisting device to make the reduction tank move downward from the inlet and outlet on the top of the furnace into the furnace. The movement exits the furnace, then hoists and unloads to the unloading position and opens the reduction tank for unloading. This type of reduction furnace has disadvantages such as complicated operation, slow heat dissipation of the heating furnace, low efficiency,...

AI Technical Summary

Problems solved by technology

This type of reduction furnace has disadvantages such as complex operation, slow heat dissipation of the heating furnace, low efficiency, unstable weighing, low service life, and inconvenient maintenance.

Moreover, the reduction tank of the existing reduction furnace adopts a long cylinder structure with one end closed and the other end open. When unloading, the material is poured out by inverting the reduction tank. It is easy to jam the material, and often the material cannot be unloaded. , it is necessary to tap the reduction tank or use tools to remove the materials in the reduction tank, resulting in easy deformation and damage of the reduction tank, reduced service life, and poor safety

In addition, the exhaust gas treatment method adopted by the existing reduction furnace is to directly blow the exhaust exhaust gas to the heating resistance wire for combustion treatment, which has the problems of low safety, poor processing efficiency and effect
