Description
Technical Field

Background
In the process for producing the titanium sponge by the magnesium method, magnesium chloride and magnesium gas remained in a distillation reactor are required to be sent into a condensation reactor through a communicating pipe for condensation, so that the magnesium chloride and the magnesium are removed, and a pure product titanium sponge is obtained. Because the condensation reactor is always in a cooling state, the internal temperature is lower (lower than the melting point of magnesium chloride and magnesium), and the magnesium chloride and magnesium gas are easily condensed on the pipe wall of the communicating pipe before entering the condensation reactor, so that the communicating pipe is blocked. The distillation time is prolonged, so that the product quality is reduced due to long-time high-temperature distillation; heavy, leading to distillation failure and equipment damage.
The communicating pipe comprises a transverse pipe and a vertical pipe, wherein the transverse pipe is communicated with the distillation reactor, and the vertical pipe is communicated with the condensation reactor. A flared conical pipe is arranged at the joint of the vertical pipe and the upper cover of the condensation reactor. Due to the proximity to the condensation reactor, the most susceptible to plugging is the standpipe and conical tube. The existing solution is to add heaters at the periphery of the horizontal pipe, the vertical pipe and the conical pipe, the shell of the heater is made of refractory bricks or ceramic fibers, most of the refractory bricks are special bricks, the manufacture is very difficult, and the heating speed is slower due to the fact that the heat accumulation of the refractory bricks is larger. The furnace type built by the ceramic fiber is limited by mechanical strength, and the furnace type is easy to damage and has short service life. The existing heater mostly adopts a mode of heating electric wires, and when the electric wires are arranged, a single group of high-power components are adopted, so that the reliability is poor, and once part of electric wires are damaged, the heating temperature is greatly influenced, so that the production continuity is not facilitated. In addition, the furnace cover and the outer cavity of the heater need to be frequently disassembled and cleaned, and vibration generated by the furnace cover and impurity particles falling into the heater can influence the service life of the electric furnace wire.
The patent with the publication number of CN203200328U discloses a titanium sponge distillation passage heating device, and a distillation passage is heated by a heating coil sleeved on the distillation passage, and the greatest defect of the patent is that the heating coil is not easy to disassemble, so that the maintenance of the distillation passage, the maintenance of a heat insulation layer and a thermocouple are very inconvenient.

Detailed Description
Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.
An inner heater of a titanium sponge condensation reactor is used for heating a communicating pipe. The communicating pipe comprises a transverse pipe, a vertical pipe 1 and a conical pipe 2, wherein the transverse pipe, the vertical pipe 1 and the conical pipe 2 are made of magnetic conductive stainless steel materials. The present embodiment uses only standpipe 1 and conical tube 2 as examples to illustrate the structure and principles of the present internal heater.
As shown in fig. 1, the internal heater is designed in a sectional manner to adapt to the wiring layout of the communication pipe. The section of the internal heater which is wrapped around the periphery of the standpipe 1 and conical tube 2 comprises a housing which is formed of an unshaped refractory material and is capable of withstanding high temperatures. In order to prevent heat loss, the outside of the shell is provided with a heat preservation layer. In order to facilitate disassembly and maintenance, in the embodiment, the shell is formed by encircling the two split bodies 3 and is detachably connected through connecting pieces such as bolts.
As shown in fig. 2, two groups of inductor coils 4 attached along the shape are arranged on the inner surface of each split body 3, and after the two groups of inductor coils 4 are connected in series, connectors extend outwards from the shell. The joints of the inductance coil plates 4 on the two-section split body 3 are connected in parallel with an external circuit, and the four groups of inductance coil plates 4 are driven by the external circuit. The number of joints and connecting points can be reduced, and potential safety hazards are reduced; secondly, the configuration quantity of external circuits is reduced, and the cost is reduced. After the external circuit applies high-frequency voltage to the inductance coil panel 4, the inductance coil panel 4 generates a high-frequency alternating magnetic field in the vertical tube 1 and the conical tube 2 to form an electric vortex, so that the vertical tube 1 and the conical tube 2 are self-inductively heated. Compared with electric stove wire heating, self-induction heating has the advantages of quick temperature rise, no radiation heat source, high heat efficiency and easier control of heating temperature.
As can be seen from fig. 2, the inductance coil disk 4 increases from inside to outside, and is attached to the inner surface of the split body 3 in a rectangular shape. The conformal fit design of the inductance coil disk 4 enables the alternating magnetic field direction generated by the inductance coil disk 4 to be perpendicular to the surfaces of the vertical pipe 1 and the conical pipe 2, and the effect is that the eddy current resistance generated in the metal is smaller, the current is larger and the heating efficiency is higher. The shape of the inductor coil 4 is not limited to this, and may be a disk shape or an elliptical shape, depending on the specific implementation conditions.
In the embodiment, the inductance coil disk 4 is attached to the inner surface of the split body 3 along with the shape, so that the inductance coil disk has the advantages of being close to the vertical pipe 1 and the conical pipe 2, strong in generated magnetic field intensity and high in heat efficiency; the disadvantage is the large temperature rise, which is unfavorable for the heat dissipation of the inductor coil 4. In order to reduce the temperature of the inductance coil 4, the inductance coil 4 is made of copper tubes, and circulating cooling liquid is introduced into the copper tubes. The inductance coil disk 4 can be attached to the outer surface of the split body 3 in a shape, and has the advantages of being beneficial to heat dissipation and low in heat efficiency, so that the inductance coil disk is required to be determined according to specific use environments.
In summary, the utility model fully considers the dismounting problem and the reliability problem of the inner heater, replaces the traditional electric wire heating by the electric vortex heating, ensures that the inner heater has simpler structure, longer service life, higher working reliability and more convenient dismounting and maintenance, and solves the difficult problem which puzzles the production of the titanium sponge for a long time.
The utility model is not described in detail in the prior art. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
