Automatic collection device for copper powder

Abstract

The invention discloses an automatic collection device for copper powder. The automatic collection device comprises a dust suction machine, a storage chamber and a discharge chamber. The storage chamber is located between the dust suction machine and the discharge chamber, the upper end of the dust suction machine is provided with a suction pipe, the top end of the suction pipe is provided with asuction inlet, one side of dust suction machine is provided with a liquid soap inlet pipe, one side of the liquid soap inlet pipe is provided with an atomizer, and one end of the liquid soap inlet pipe is connected with a liquid spraying pipe. By means of the liquid soap inlet pipe, liquid soap, gelatin, protein hydrolysate and other antioxidants can be guided into the collection device; and sincethe atomizer is arranged on the liquid soap inlet pipe, liquid water can be conveniently converted into mist-like small-particle gas, the surface of copper powder is sprayed through multiple sets ofliquid spray heads below the liquid spraying pipe connected with the bottom end of the atomizer, the surface of the copper powder will be adsorbed and covered with a layer of film, the oxidation-resisting corrosion inhibition effect is achieved, and the service life can be prolonged.

Description

technical field [0001] The invention relates to an automatic collecting device, in particular to an automatic collecting device for copper powder. Background technique [0002] Copper powder, main application: Widely used in powder metallurgy, electric carbon products, electronic materials, metal coatings, chemical catalysts, filters, heat pipes and other electromechanical parts and electronic aviation fields. [0003] Copper is unstable in the air, so it is inevitable that the copper powder will be oxidized in the air. At this time, it is necessary to isolate the air for collection. However, in a humid environment, the surface of the copper powder is easy to absorb water vapor in the air to form a water film. Moreover, due to the thick water film formed on the concave part of the surface of the particle, the penetration of oxygen is less, and the oxygen concentration is low, so it becomes a micro-anode, and a micro-cathode is formed on the convex part where oxygen is easy t...

[0003] Copper is unstable in the air, so it is inevitable that the copper powder will be oxidized in the air. At this time, it is necessary to isolate the air for collection. However, in a humid environment, the surface of the copper powder is easy to absorb water vapor in the air to form a water film. Moreover, due to the thick water film formed on the concave part of the surface of the particle, the penetration of oxygen is less, and the oxygen concentration is low, so it becomes a micro-anode, and a micro-cathode is formed on the convex part where oxygen is easy to reach. Battery effect, copper powder is gradually oxidized, which will lead to short service life, and copper powder is harmful to the environment, causing slight pollution to water, soil and the atmosphere
