A stirring and feeding mechanism

Abstract

The invention provides a stirring and conveying mechanism. A stirring mechanism penetrates through a furnace lid from the interior of a furnace chamber, extends outside and is supported outside on a mounting plate on the furnace lid; outside the furnace chamber, a transmission system and a second hydraulic cylinder are connected between the mounting plate and the stirring mechanism and are used for providing rotating and stretching power for the stirring mechanism respectively; a conveying mechanism comprises an air compressor, a feeding tank, a conveying pipe and a support seat; the support seat is located below the feeding tank and is used for supporting and fixing the feeding tank; two ends of the feeding tank are connected with the air compressor and the conveying pipe through connectors respectively; and the tail end of the conveying pipe is communicated with a center through hole of a graphite bell jar for a molten metal stirrer. Through the design and use of the structure, the stability of ingot quality can be guaranteed, so that the stability and reliability of later-period experiment data are guaranteed.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to a stirring and feeding mechanism for an aluminum alloy smelting device. Background technique [0002] When the laboratory uses an ordinary crucible resistance furnace to smelt aluminum alloy, it is difficult to simulate the industrial production site, and many problems will be encountered during the experiment: [0003] 1. Ordinary crucible resistance furnaces do not have a stirring device, and manual stirring or other mixers are needed, which is difficult to ensure that the alloying elements are evenly distributed in the melt and ensure the quality of the melt; [0004] 2. Ordinary crucible resistance furnaces are not equipped with feeding devices. When adding metals or powdery refining agents and sodium salt modifiers that are lighter than aluminum liquids into the aluminum liquid, it is necessary to manually press them into the aluminum liquid with special equipment, resulting in...

Problems solved by technology

[0002] When the laboratory uses an ordinary crucible resistance furnace to smelt aluminum alloy, it is difficult to simulate the industrial production site, and many problems will be encountered during the experiment:

[0003] 1. Ordinary crucible resistance furnaces do not have a stirring device, and manual stirring or other mixers are needed, which is difficult to ensure that the alloying elements are evenly distributed in the melt and ensure the quality of the melt;

[0004] 2. Ordinary crucible resistance furnaces are not equipped with feeding devices. When adding metals or powdered refining agents and sodium salt modifiers that are lighter than aluminum liquids into the aluminum liquid, it is necessary to manually press them into the aluminum liquid with special equipment, resulting in Insufficient dissolution of the added materials and severe burning loss will affect the quality of the solution, especially when sodium salt modifier is added, the sodium salt is easy to stick to the bell jar, thus affecting the effect of modification
