Problems solved by technology

[0003] The existing ladles on the market do not have the function of heat preservation, and the molten aluminum is easily cooled during transportation, which affects the casting quality of aluminum products
Secondly, the transfer efficiency of molten aluminum using ladles is low, and the round-trip transportation of ladles increases production costs
In addition, there are potential safety hazards in the ladle during transportation. Once the ladle falls and overturns, it will cause very serious harm.

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] This embodiment proposes a liquid aluminum transport pipeline system, such as figure 1 As shown ((the illustration only takes a representative small section of the pipeline system), it includes the aluminum liquid electromagnetic pump 1, the heat preservation pipe 2 and the heating pipe 3, and the aluminum liquid electromagnetic pump 1, the heat preservation pipe 2 and the heating pipe 3 pass through Flanges are connected with bolts.

[0048] The molten aluminum electromagnetic pump 1 is installed at the initial end of the pipeline system, and its main function is to provide power for the molten aluminum flowing into the pipeline and increase the flow speed of the molten aluminum. Here, the molten aluminum electromagnetic pump 1 is a three-phase planar induction electromagnetic pump, and its structure is as follows figure 2 , 3 shown.

Abstract

The invention discloses a molten aluminum conveying pipeline system which comprises a molten aluminum electromagnetic pump, an insulation pipeline and a heating pipeline; the molten aluminum electromagnetic pump, the insulation pipeline and the heating pipeline are connected with one another through flange discs and bolts; and the electromagnetic pump is a three-phase plane induction type electromagnetic pump. By utilizing a pipeline conveying manner to replace the traditional pouring ladle conveying manner, the molten aluminum conveying pipeline system provided by the invention not only can perform heating treatment on molten aluminum in the transportation process, strengthen the insulation effect, but also is high in transmission efficiency of the molten aluminum and safe and stable in transmission process.

Description

technical field [0001] The invention relates to a special pipeline transportation system, in particular to a liquid aluminum transportation pipeline system. Background technique [0002] At present, in the production process of aluminum products, after the smelter melts and refines the aluminum liquid in the smelting workshop, it needs to pour the high-temperature aluminum liquid into each ladle, and then transport the ladle to the casting workshop for pouring. If the casting workshop It is far away from the smelting workshop, and it is necessary to use special vehicles to transfer the ladle. [0003] The existing ladles on the market do not have the function of heat preservation, and the molten aluminum is easily cooled during transportation, which affects the casting quality of aluminum products. Secondly, the transfer efficiency of molten aluminum by ladles is low, and the round-trip transportation of ladles increases production costs. In addition, there are potential s...
