A calcium oxide particle removal device for preparing foamed aluminum by percolation method

Abstract

The invention discloses a device for removing calcium oxide particles for preparing foamed aluminum by a percolation method, which includes a separator, the separator includes a first tank body and a first cover body, and the first tank body and the first cover body Sealed connection, the first tank is used to contain saturated ammonium chloride aqueous solution, and the first cover is provided with a first air pumping mechanism communicating with the outside world. The present invention is aimed at removing the calcium oxide particles prepared by the percolation method to prepare foamed aluminum, put the composite of calcium oxide particles and aluminum into the saturated ammonium chloride aqueous solution contained in the first tank, and the calcium oxide particles and the saturated calcium chloride aqueous solution The reaction generates calcium chloride, and after the reaction is completed, the calcium oxide particles are removed to obtain a foamed aluminum material, and the ammonia gas generated by the reaction is exported by the first pumping mechanism. The calcium oxide particle removal device of the present invention can quickly and completely remove the calcium oxide particles, has a simple overall structure, is easy to manufacture, and saves production costs.

Description

technical field [0001] The invention relates to the field of foamed aluminum manufacturing equipment, in particular to a calcium oxide particle removal device for preparing foamed aluminum by a seepage method. Background technique [0002] Aluminum foam is made by adding additives to pure aluminum or aluminum alloy and undergoing a foaming process, which has both metal and bubble characteristics. Aluminum foam also has low density, high impact absorption ability, high temperature resistance, strong fire performance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, It has many advantages such as high forming precision and surface coating. Because aluminum foam has excellent physical properties, chemical properties, mechanical properties and recyclability, these excellent properties make it have broad application prospects in t...

AI Technical Summary

Problems solved by technology

However, when table salt is used as the seepage particle, the table salt contains crystal water, which leads to unstable particle size and is also corrosive to the foamed aluminum material.

The patent number is 201610242168.2, which proposes a preparation method of foamed aluminum material with calcium oxide as seepage particles. Using calcium oxide as seepage particles solves the problem of instability during particle preheating, which is equally important as particle stability. It is the removal of particles, which directly affects the uniformity, porosity and porosity of the aluminum foam material.
