Problems solved by technology

[0002] At present, the metal purification devices used in metal processing projects have complex structures, high costs, long processing and purification cycles, and large energy losses, which are not suitable for processing and purifying small batches of metal parts.
There is a two-step metal purification furnace including electric control equipment and an electric furnace body. The furnace body is made of refractory bricks, and the two ends are connected to metal electrodes. This furnace body structure solves the problem of the furnace body well. problem, but the sealing effect of the furnace body is poor, resulting in poor temperature regulation and control ability, which has a certain impact on the purification quality of metal parts

Abstract

The invention discloses a metal purification furnace. The metal purification furnace comprises a cylindrical furnace body, an upper cover and a heater, wherein the upper cover covers the upper end of the furnace body and is locked through a flange structure; an air suction hole is formed in the upper cover; a temperature adjusting layer and a heat insulation layer are arranged on the wall of the cavity of the furnace body in sequence; a heater is arranged in the heat insulation layer; the distances between positions of the outer wall of the heater and positions of the inner wall of the heat insulation layer are the same and are not equal to zero; and an air conveying hole is formed in the bottom end of the cylindrical side surface of the furnace body. The metal purification furnace provided by the invention is simple in structure and high in sealing performance and has a temperature adjusting function.

Description

technical field [0001] The invention relates to a metal processing and purification device, in particular to a metal purification furnace. Background technique [0002] At present, the metal purification devices used in metal processing projects have complex structures, high costs, long processing and purification cycles, and large energy losses, which are not suitable for processing and purifying small batches of metal parts. There is a metal purification furnace consisting of electric control equipment and an electric furnace body in two steps. The furnace body is made of refractory bricks and connected to metal electrodes at both ends. This furnace body structure solves the problem of the furnace body well. problem, but the sealing effect of the furnace body is poor, resulting in poor temperature regulation and control ability, which has a certain impact on the purification quality of metal parts. Contents of the invention [0003] Purpose of the invention: In order to...
