Aluminum scrap depositing and melting device

Abstract

The invention relates to an aluminum scrap depositing and melting device, which mainly comprises a main melting chamber, an electromagnetic pump, a charging well and a connecting pipeline, wherein the main melting chamber is connected with the charging well through a feed pipe and the electromagnetic pump arranged on the feed pipe; the charging well is connected with the main melting chamber through a return pipe arranged at the bottom to form a circulation loop; the charging well has a cylindrical bucket body structure; the cross sections of the feed pipe and the return pipe are round; the connecting angle between the feed pipe and the charging well in the vertical direction is between 91 and 93 degrees; and the connecting angle between the return pipe and the charging well is between 91 and 93 degrees. The angle for the feed pipe entering the charging well in the horizontal direction enables the molten aluminum to simultaneously have a tangential velocity and a normal velocity relative to the round cross section of the charging well, the mounting position of the return pipe is favorable for the formation of a vortex, and the size of the pipe diameter ensures the liquid height in the charging well so that the molten aluminum forms the vortex with high vortex strength in the charging well and can quickly entrain and cover the aluminum scraps added into the charging well. The depositing and melting device has high depositing and melting capability and high production efficiency.

Description

technical field [0001] The invention relates to an aluminum scrap recycling melting furnace, in particular to a high-efficiency aluminum scrap sinking and melting equipment. Background technique [0002] At present, there are mainly the following methods for the recovery and melting of aluminum chips: first, direct heating and melting, which consumes a lot of energy and causes serious environmental pollution. In addition, the biggest problem is oxidation and burning. For small-sized aluminum chips It is said that the oxidation and burning loss of this melting method is quite serious, resulting in a great waste of resources; second, the aluminum scraps are packed and extruded into blocks and then added to the furnace for melting, although the oxidation and burning loss is much lower than that of aluminum scraps directly added to the melting chamber, But the burning loss rate is still as high as 10-15%; the third is the molten aluminum covering melting technology, which puts t...
