Temperature measurable aluminum smelting bell jar

Abstract

The invention provides a temperature measurable aluminum smelting bell jar comprising a first handle, a second handle, a thermocouple and a digital display, the first handle and the second handle are same in length and are in hinge joint by a rotating shaft, the first handle is internally hollow and provided with a wire, the wire connects the thermocouple and the digital display, and the temperature measurable aluminum smelting bell jar also includes a first clip and a second clip; the first handle is connected with the first clip by a barrel type fastening connector, the second handle is connected with the second clip by a barrel type fastening connector, the first clip and the second clip both comprise a connecting rod and a porous hollow hemisphere, the connecting rod of the first clip is internally hollow, the porous hollow hemispheres are same in diameter and coaxial, the porous hollow hemispheres can be combined into a hollow sphere, and the thermocouple is located within the first clip. The temperature measurable aluminum smelting bell jar can realize the additive clamping, pressing and other operation, can display temperature of a melt in real time, has the advantages of simple structure, graphite clip material, small pollution to the melt, detachable clips and handles, and easy installation and replacement.

Description

technical field [0001] The invention relates to a temperature-measurable bell jar for aluminum smelting. Background technique [0002] In the casting process of metal aluminum, some additives need to be added, which can play a role in degassing, deterioration or refinement. Additives need to be added to the aluminum melt to exert the greatest effect, but these additives often float in the aluminum liquid. On the surface, it is necessary to use a bell jar to press it into the molten aluminum to react. Secondly, when the crucible is small, it is difficult to accurately put the additive into the crucible. Sometimes the additive will fall out of the crucible, but the existing bell jar does not have Additives cannot be accurately added to the crucible due to the support function. In addition, it is often necessary to measure the temperature inside the melt while adding additives, and the existing bell jar cannot solve this problem. Contents of the invention [0003] In order ...
