Novel rare earth metal molten finished product siphon pipeline

Abstract

The invention discloses a novel rare earth metal molten finished product siphon pipeline, which comprises a smelting furnace, a fixed box and a base; the upper surface of the smelting furnace is fixedly connected with a feeding pipe; the inner wall of the feeding pipe is in threaded connection with a sealing cover; the inner top wall of the smelting furnace is fixedly connected with a guide pipe and an air outlet pipe; the surface of the guide pipe is sleeved with a heat preservation device; the surface of the guide pipe is fixedly connected with an air inlet fan and a ceramic block; the surface of the ceramic block is fixedly connected with a heating plate; the surface of the heat preservation device is fixedly connected with a temperature sensor; and the end, away from the smelting furnace, of the guide pipe extends into the fixed box. According to the novel rare earth metal molten finished product siphon pipeline provided by the invention, by arranging the heat preservation device, the air outlet pipe, the ceramic block, the heating plate and the air inlet fan, hot air in the smelting furnace can enter a cavity formed by the guide pipe and the heat preservation device from the air outlet pipe, the heating plate heats air, and the air inlet fan blows the heated air into the whole cavity, thus the heat preservation effect on the guide pipe is improved.

Description

technical field [0001] The invention relates to the technical field of siphon tubes, in particular to a novel siphon tube of rare earth metal melting products. Background technique [0002] Rare earth metals, also known as rare earth elements, is the general term for the 17 elements of scandium, yttrium, and lanthanide in group IIIB of the periodic table of elements. It is often represented by R or RE. From the discovery of the first rare earth element yttrium in 1794 to the discovery of natural rare earths in 1972 It took 178 years for the element promethium to find all 17 rare earth elements in nature. The luster of rare earth metals is between silver and iron, and the chemical activity of rare earth metals is very strong. [0003] The heat preservation effect of the existing siphon pipes of molten rare earth metal products is not ideal, and the siphon pipes cannot be kept at a constant temperature, so the pipes are prone to be blocked by metal due to sudden cooling of the...

Problems solved by technology

[0003] The heat preservation effect of the existing siphon pipes made of molten rare earth metals is not ideal, and the siphon pipes cannot be kept at a constant temperature, which is prone to blockage of pipes by metals due to sudden cooling of the pipes, and is not practical.
