Copper powder drying device

Abstract

The invention relates to a copper powder drying device. The copper powder drying device comprises a machine enclosure, wherein a necking type discharge hole is formed in the lower end of the machine enclosure; a charge hole and a vacuum breaking valve are arranged at the upper end of the machine enclosure; an inert gas pipeline is arranged on the side wall of the machine enclosure; vacuum gas exhaust holes are formed in the two sides of the necking type discharge hole; the vacuum gas exhaust holes are connected to a vacuum pump; metal screen boards are arranged in the vacuum gas exhaust holes; the metal screen boards are equipped with filter layers; a rotary shaft which penetrates through the machine enclosure is arranged in the machine enclosure; one side of the machine enclosure is equipped with a motor which is connected with the rotary shaft; a heating tube is arranged in the rotary shaft; a plurality of pairs of heating shafts extend out from the rotary shaft; included angles between the heating shafts and the rotary shaft are 45-60 degrees; and protective layers are connected outside the heating shafts in a sleeving mode. The copper powder drying device has the advantages that: the heating shafts extend out from the rotary shaft, so that a temperature in the machine enclosure can be quickly increased, and copper powder drying speed is increased; the spiral protective layers are arranged outside the heating shafts in the sleeving mode, so that the heating shafts are protected, the service lives of the heating shafts are prolonged; and moreover, the spiral protective layers further can be used as stirring shafts for loosening copper powder.

Description

technical field [0001] The invention relates to a drying device, in particular to a copper powder drying device. Background technique [0002] Atomized copper powder is further processed from electrolytic copper. It is a light rose red dendritic powder. It is easy to oxidize in humid air and can be dissolved in hot sulfuric acid or nitric acid. In the current production and processing process, copper powder needs to be dried There are many ways to deal with it, but it is difficult and difficult to operate, which virtually increases the production cost of the enterprise. There is an urgent need for a safe and simple copper powder dryer, which not only increases production efficiency but also ensures production safety. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0003] The object of the invention is to provide a copper powder drying device. [0004] In order to achieve the above object, the technical schem...
