Description

Technical Field

[0001] This utility model relates to the field of sponge titanium smelting technology, and in particular to an electromagnetic heater structure at the connection of a sponge titanium cooling tank. Background Technology

[0002] The current smelting process for novel sponge titanium incorporates a connection between the reaction vessel and the cooling vessel, allowing reduction and distillation to be completed in a single operation. Therefore, the connection device between the reaction vessel and the cooling vessel becomes a critical piece of equipment. This connection device needs to operate normally at temperatures above 850°C. Current heating methods employ electromagnetic heating, utilizing the principle of electromagnetic induction. A high-frequency alternating current is passed into a coil wound around the tube at the connection point, generating an alternating magnetic field. The magnetic lines of force cut through the metal tube at the connection point, generating eddy currents. These eddy current collisions rapidly heat the tube at the connection point.

[0003] The connection between the heating tube and the cooling tank consists of a vertical tube and a conical heating element welded together. The vertical tube is welded to the bottom plate of the furnace cover of the reaction vessel and the cooling tank. The rare metal coil is attached to the outside of the conical heating element and consists of two semi-circular conical coils. The coil is covered with heat-insulating cotton that can withstand 1250℃ and compacted. The insulation device is protected by a 304 metal cover.

[0004] The existing heaters at the connection between the reaction vessel and the cooling vessel have the following technical problems: In the high-temperature reaction vessel, gaseous sponge titanium is formed. The cool water sprayed at the connection between the reaction vessel and the cooling vessel and outside the cooling vessel causes the gaseous sponge titanium to cool down rapidly. Therefore, it is easy for gas condensation to form at the outlet of the connection between the reaction vessel and the cooling vessel and at the top of the cooling vessel, which can lead to blockage. Utility Model Content

[0005] The purpose of this invention is to provide an electromagnetic heater structure for the connection of a titanium sponge cooling tank, which solves the problem that in ordinary electromagnetic heaters at the connection of titanium sponge cooling tanks, gaseous titanium sponge is formed in the high-temperature reaction tank, and the gaseous titanium sponge is rapidly cooled by the cold water sprayed at the connection between the reaction tank and the cooling tank and outside the cooling tank, thus easily forming condensation at the outlet of the connection between the reaction tank and the cooling tank and at the top of the cooling tank.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an electromagnetic heater structure at the connection of a titanium sponge cooling tank, including an outer cover, a conical connecting body structure, and an electromagnetic heating component disposed in the conical connecting body structure. The conical connecting body structure includes a conical heating body structure and a temperature sensor component connected to the conical heating body structure. The conical heating body structure includes a bottom conical heating section, a middle connecting section disposed at the upper part of the bottom conical heating section, and a process pipeline connecting section. The electromagnetic heating component is disposed outside the bottom conical heating section. The temperature sensor component includes a lower temperature sensor connected to the bottom heating end and an upper temperature sensor connected to the process pipeline connecting section.

[0007] The electromagnetic heating assembly includes a heating fixture group evenly distributed on the outer surface of the bottom conical heating section and an electromagnetic heating coil disposed between the heating fixture group and the bottom heating end.

[0008] The bottom conical heating section includes a conical inner layer and a set of external heating connectors located outside the conical inner layer.

[0009] The heating fixing assembly includes an upper L-shaped fixing rod and a lower L-shaped fixing rod arranged opposite to each other.

[0010] A connecting flange is provided between the middle connecting section and the process pipeline connecting section.

[0012] This invention uses a reducing joint to transition between the heater's vertical tube and the reaction vessel. The reducing joint increases the outlet area of ​​the outlet pipe at the connection between the vertical tube reaction vessel and the cooling tank, thus solving the problem of condensation blockage at the outlet of the connection between the vertical tube reaction vessel and the cooling tank and at the top of the cooling tank.
