Abstract

The invention discloses a catalytic debinding furnace with an atmosphere purifying function. The catalytic debinding furnace comprises a furnace body and an atmosphere purifying and separating device matched with the furnace body, wherein a furnace container outer cover is arranged inside the furnace body; a debinding furnace container is arranged inside the furnace container outer cover; a material carrying tank for bearing materials is arranged inside the debinding furnace container; furnace body heating wires are arranged between the furnace container outer cover and the debinding furnace container; a furnace door assembly which can seal the furnace container outer cover in a matching manner is arranged at the side part of the furnace body; the atmosphere purifying and separating device is provided with a gas inlet channel and a gas outlet channel which are respectively communicated with the debinding furnace container and the material carrying tank. The catalytic debinding furnace with the atmosphere purifying function has the advantages of cost reduction, less environmental pollution, better product quality, high safety performance, high explosion-proof performance and the like, which are not embodied in the prior art.

Description

Technical field [0001] The invention relates to a processing equipment in the field of powder metallurgy, in particular to a catalytic degreasing furnace with atmosphere purification function. Background technique [0002] The process principle of catalytic degreasing is to use the characteristic of solid polyformaldehyde (POM) to quickly crack into gaseous formaldehyde molecules under an acidic atmosphere at a certain temperature (about 100°C), in which acid exists as a catalyst. The cracking equation is as follows: [0003] (CH 2 O) n (Acid solution)——→nCH 2 O [0004] At present, the commonly used catalyst in the catalytic degreasing process is nitric acid (HNO 3 ), strong oxidizing nitric acid (HNO 3 ) It can quickly catalytically crack POM and is widely used in industrial production. However, nitric acid is extremely dangerous. It can burn human skin, damage the mucous membranes and respiratory tracts of the human body. When in contact with protein, it will produce a bright ye...
