High temperature melt granulation furnace

Abstract

The invention discloses a high-temperature melt granulation smelting furnace which comprises a metal shell, wherein the metal shell is sealed by a heating furnace closed cover. The high-temperature melt granulation smelting furnace is characterized in that a partition plate is arranged in the metal shell, the inside of the metal shell is divided into an upper box and a lower box by the partition plate, a center through hole is formed in the partition plate, a crucible is placed on the partition plate and provided with a funnel-shaped bottom, a discharging hole is formed in the bottom of the crucible, the bottom of the crucible penetrates the center through hole and is inserted into the lower box, a heat insulation layer is arranged between the wall of the crucible and the inner wall of the metal shell, a discharging port is formed in the bottom of the metal shell and corresponds to the discharging hole, a through hole is formed in the heating furnace closed cover, one end of a lifting bar penetrates the through hole and is inserted into the crucible, the discharging hole is plugged, the other end of the lifting bar is arranged outside the heating furnace closed cover and is connected with a rotating wheel through a connecting rod, and a vacuum pumping pipe, an air inflation pipe and an exhaust pipe are arranged in the metal shell. The high-temperature melt granulation smelting furnace can generate high-temperature molten particles meeting requirements and can be widely applied to the fields of chemical industries, steel and the like.

Description

technical field [0001] The invention relates to a melting furnace, in particular to a high-temperature melt granulation melting furnace. Background technique [0002] The crucibles used in existing high-temperature furnaces are generally graphite crucibles, and the outside is an incubator. The working fluid in the graphite crucible is melted by heating, and the molten working fluid drops freely from the small hole at the bottom of the crucible. There are two problems with the current device: first, the graphite crucible is severely damaged. The graphite crucible begins to chemically react with oxygen in the air at 400°C, so the high temperature environment during the heating process causes the graphite crucible to oxidize violently and consume rapidly, making it impossible to carry out the next experiment. Second, molten particles cannot drip smoothly from the small hole at the bottom. Since the viscosity of the working fluid changes greatly during the heat preservation p...
