Degreasing hot air circulating furnace for zirconia ceramic materials

Abstract

The invention discloses a degreasing hot air circulating furnace for zirconia ceramic materials, and belongs to the technical field of degreasing hot air circulation. The degreasing hot air circulating furnace comprises a furnace body with two supporting legs at the bottom, a PLC control face board, a furnace chamber, two vertical mesh plates and two U-shaped slide rails, wherein the PLC control face board is arranged on the right side of the front surface of the furnace body and used for power control and intelligent temperature control processing of the whole circulating furnace, and the furnace chamber is formed in the left side of the front surface of the furnace body; the two vertical mesh plates are arranged between the upper inner wall and the lower inner wall of the furnace chamber, one of the vertical mesh plates is arranged on the left inner wall of the furnace chamber, and a containing space is reserved between the other vertical mesh plate and the right inner wall of the furnace chamber; and the two U-shaped slide rails are arranged on the two vertical mesh plates. According to the degreasing hot air circulating furnace for the zirconia ceramic materials, the extremelyunique circulating principle that the air volume is timely adjustable is adopted, a plurality of air inlets are designed, the air speed is continuously adjustable, a non-direct heating mode is adoptedin thermal engineering, and heated hot air is subjected to heat transfer through convection, so that the heat efficiency is greatly improved, the dead angle area is reduced, and therefore the percentof pass of degreasing is increased.

Description

technical field [0001] The invention relates to the technical field of degreasing hot air circulation, in particular to a degreasing hot air circulation furnace made of zirconia ceramic material. Background technique [0002] Zirconia ceramics are white, yellow or gray when they contain impurities, and generally contain HfO2, which is not easy to separate. There are three crystal states of pure ZrO2 under normal pressure. The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion, ultrafine particles and narrow particle size distribution. There are many methods for preparing zirconia ultrafine powders, and degreasing of zirconia is one of the processes. [0003] When degreasing zirconia ceramic materials, it is necessary to use a heating furnace to heat it. However, the existing heating furnace cannot be continuously adjusted during air circulation, resulting in unadjustable air volume, resulting in low heat exchange and degrea...

Problems solved by technology

[0003] When degreasing zirconia ceramic materials, it is necessary to use a heating furnace to heat it, but the existing heating furnace cannot be continuously adjusted during air circulation, resulting in unadjustable air volume, resulting in low heat exchange and degreasing efficiency, and at the same time Most of the existing heating furnaces use direct heating, which has certain safety hazards and is not environmentally friendly.
