Tackifying and foaming stirring device for preparing foamed aluminum

Abstract

The invention discloses a tackifying and foaming stirring device for preparing foamed aluminum, relates to a stirring device, and solves the problem that the high-quality foamed aluminum cannot be prepared by adopting the existing forming device. The tackifying and foaming stirring device for preparing the foamed aluminum comprises a cylindrical stirring furnace body, wherein a heating device is fixed outside the furnace body, a stirring paddle is arranged inside the furnace body, and the stirring paddle is installed on a furnace cover; the stirring paddle is in a four-layer folded-blade paddle form, four layers of paddle blades are arranged on a central shaft of the stirring paddle, each layer is provided with three paddle blades, the paddle blades at each layer are arranged to stagger each other for 120 degrees, a dip angle of the paddle blades at the lowermost layer is smaller than that of the paddle blades at the upper three layers, and the upper part of the central shaft is fixed on the furnace cover through a fixing disc and the central shaft driven by a motor to rotate. The tackifying and foaming stirring device is simple in structure, ingenious in design, capable of uniformly and rapidly stirring metal liquid by virtue of the four-layer paddle blades and good in foaming effect.

Description

technical field [0001] The invention relates to stirring equipment, in particular to a thickening and foaming stirring device for preparing foamed aluminum. Background technique [0002] At present, when the melt foaming method is used to prepare aluminum foam, the stirring equipment used for thickening and foaming is generally a single-layer paddle stirrer, or a titanium alloy stirring paddle with a three-layer blade structure. During the operation of the single-layer paddle agitator, the melt will form a deep vortex, which cannot effectively disperse the titanium hydride particles, and the melt in the lower part of the agitator is easy to inhale, resulting in the formation of a large number of bubbles inside the foam. Irregular pores; the titanium alloy stirring paddle has a three-layer blade structure, and its blades are bent downward to form a 30° angle with the horizontal plane. Since the bottom of the stirring furnace is semicircular, when in use, a part of the aluminu...
