Embodiment 1

[0033] Such as figure 2 As shown, a rotating and stirring aluminum liquid foaming mechanism includes:

[0034] Foaming warehouse 1 arranged in a barrel shape;

[0035] The drive assembly 2 fixedly arranged above the foaming bin 1;

[0036] The gas pipe 3 is installed on the top of the foaming bin 1 and connected to the drive assembly 2 while rotating in the vertical direction, and the foaming gas inside the gas pipe 3 is opened outside Several air holes 31 on the circumferential surface perform gas foaming of the molten aluminum in the foaming chamber 1;

[0037] A guide plate 32 is fixedly provided on the outer circumferential surface of the air pipe 3 with a number of guide plates 32 spirally arranged around its axis. The guide plates 32 are located above and corresponding to the air holes 31.

[0038] Further, the bottom end of the gas pipe 3 is closed, and a slit 33 is opened on the outer circumferential surface above it. The foaming gas is sprayed through the slit 33 to form a ga...

Embodiment 2

[0048] The components that are the same as or corresponding to those in the first embodiment use the reference numerals corresponding to the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the guide plates 32 are evenly arranged along the outer circumferential surface of the air pipe 3 and are on the same horizontal plane. The number of the guide plates 32 is four to ensure that the guide plates 32 are foamed. The tank 1 can stir the molten aluminum more fully, so that the molten aluminum foams more fully.

[0049] work process:

[0050] The gas transmission device inputs gas into the gas transmission pipe 3, and the gas transmission pipe 3 continuously inputs gas into the foaming chamber 1 through the gas transmission holes 31 and the slit 33. The gas output through the slit 33 continuously moves from bottom to top due to its own character...

Abstract

The invention relates to a rotating and stirring aluminum liquid foaming mechanism, which includes a foaming chamber, a rotating driving part, an air delivery pipe and an air delivery device. A number of air delivery holes are evenly opened on the outer circumference of the air delivery pipe, and on the There is a guide plate above the gas delivery hole. The guide plate drains the gas flowing out of the gas delivery hole, which increases the gas flow path and increases the contact time between the aluminum liquid and the gas. The rotating drive part is fixedly connected with the gas delivery tube to drive the gas delivery tube Rotating, the guide plate set on the infusion tube continuously stirs the aluminum liquid in the foaming chamber, which solves the technical problems of low foaming rate of aluminum liquid and uneven distribution of bubbles.

Description

Technical field [0001] The invention belongs to the field of foamed aluminum production, and particularly relates to a rotating stirring aluminum liquid foaming mechanism. Background technique [0002] Due to aluminum's low density, high rigidity, corrosion resistance and good processability, the application of aluminum continues to increase. This trend is particularly obvious in the automotive industry, household appliances and the construction industry. In these fields, there is a huge demand for aluminum with complex shapes and high strength. However, there is gas in the preparation process of foamed aluminum in the prior art. Many defects such as inability to fully contact with liquid, uneven distribution of bubbles, and low foaming rate. [0003] The invention patent with the Chinese invention application number 201410236790.3 discloses an automatic foaming aluminum liquid blowing system, which is the automatic rotation of the blowing type foamed aluminum insulation pool in t...
