Debinding furnace

Abstract

The invention discloses a debinding furnace and relates to the field of industrial furnaces, in particular to a drying debinding furnace for a ceramic ferrule for a photo-communication passive device. A hearth and a heating cavity welded by heat-resistant stainless steel plates are respectively formed in a mechanical frame; the hearth, the heating cavity, a hearth bottom plate and mesh plates on left and right sides of the hearth form an entire circulating air duct; an axial flow circulating fan is arranged inside the circulating air duct and is arranged on the right side of the hearth; and hot wind in the circulating air duct enters the hearth through the mesh plate on the right side of the hearth. The mesh plates are fixed on the left and right sides of the hearth; a slideway is fixed on a vertical steel bar of each mesh plate; the hearth bottom plate, the mesh plates on the two sides and the slideway are detachable; a hot-wind circulating system adopts an extremely-unique and timely air quantity-adjustable hot-wind circulating mode; the axial flow circulating fan regulates the speed by frequency conversion, the speed is continuously adjustable, the heat efficiency is greatly improved and the dead-space region is effectively reduced. A resistance wire has the characteristics of high material purity, stable performance, longer service life, high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of industrial furnaces, in particular to a drying and degreasing furnace for ceramic ferrules of optical communication passive devices. Background technique [0002] The fiber optic connector that transmits optical signals, its core and basic components are ceramic ferrules. In order to adapt to the complexity of the use environment of optical fiber connectors and series of optical communication products and the repeatability of insertion, the ceramic ferrule is made of zirconia non-metallic inorganic high-performance structural ceramic materials as its manufacturing material. Zirconia ceramic materials are used in Previously, one of the heat treatment processes carried out was drying and degreasing at 500°C, and the equipment used was a degreasing furnace. The degreasing furnaces currently used in the market are prone to dead angles during the heating process because the heating elements are arranged on both sides o...

AI Technical Summary

Problems solved by technology

The degreasing furnaces currently used in the market are prone to dead angles during the heating process because the heating elements are arranged on both sides of the furnace. At the same time, the temperature in the furnace is not uniform, resulting in different degreasing degrees of products and low product quality.

In addition, the effective area of ​​the furnace of traditional equipment is low, and the output is not high, which is only suitable for scientific research and experimentation, and cannot reach mass production
