Description

Technical Field

[0001] This utility model relates to a production apparatus for sponge titanium, and particularly to a heating device for a sponge titanium production reactor. Background Technology

[0002] The industrial production of sponge titanium uses the magnesium reduction of titanium tetrachloride method. Most furnaces adopt a combined inverted "U" shaped production method, which is characterized by high output per furnace, high yield of superior grade products, and low energy consumption.

[0003] The production process consists of two stages: reduction and distillation. In the reduction stage, magnesium is used to reduce titanium tetrachloride in a reduction furnace, releasing a large amount of heat and producing titanium and magnesium chloride. In the distillation stage, the magnesium and magnesium chloride from the reduction furnace are distilled into a cold-end system to obtain pure sponge titanium. Before entering the system, the reactor in the cold-end system must be free of moisture; otherwise, product quality will be affected. In existing cold-end system reactors, a small amount of chloride adheres to the inner wall at room temperature before assembly, making them prone to absorbing moisture from the air and affecting product quality during production. This paper provides a heating device for the sponge titanium production reactor to improve product quality. Utility Model Content

[0004] This invention aims to solve the technical problem that a small amount of chloride adheres to the inner wall of the cold-end reactor when it is at room temperature, making it prone to absorbing moisture from the air.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A heating device for a sponge titanium production reactor mainly consists of a lower flange of the reactor connected to a flange, with a sealing gasket provided between the lower flange and the flange.

[0007] An inner cylinder and an outer cylinder are provided at the lower part of the flange. The inner cylinder and the outer cylinder are open at the top and sealed at the bottom. An insulation layer is provided between the inner cylinder and the outer cylinder.

[0008] An air inlet pipe is provided on the lower side of the cylinder, and valve A is provided on the air inlet pipe;

[0009] A temperature measuring tube and a venting pipe are installed at the upper part of the cylinder. A pressure gauge and valve B are installed on the venting pipe.

[0010] The pressure gauge is located at the front end of valve B.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] 1. This utility model enables the drying of the reactor during the distillation production of sponge titanium, avoiding moisture absorption and ensuring the production quality of sponge titanium.

[0013] 2. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model.

[0015] In the diagram: 1 - Reactor, 2 - Sealing gasket, 3 - Flange, 4 - Outer cylinder, 5 - Inner cylinder, 6 - Temperature measuring tube, 7 - Insulation layer, 8 - Air inlet pipe, 9 - Valve A, 10 - Vent pipe, 11 - Pressure gauge, 12 - Valve B. Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0017] like Figure 1 As shown, a heating device for a sponge titanium production reactor is mainly composed of a lower flange of reactor 1 and a flange 3 connected together, with a sealing gasket 2 provided between the lower flange of reactor 1 and the flange 3.

[0018] An inner cylinder 5 and an outer cylinder 4 are provided at the lower part of the flange 3. The inner cylinder 5 and the outer cylinder 4 are open at the top and sealed at the bottom. An insulation layer 7 is provided between the inner cylinder 5 and the outer cylinder 4.

[0019] An air inlet pipe 8 is provided on the lower part of the side of the cylinder 5, and the air inlet pipe 8 is equipped with a valve A9;

[0020] A temperature measuring tube 6 and a venting pipe 10 are provided on the upper part of the cylinder 5. A pressure gauge 11 and a valve B12 are provided on the venting pipe 10.

[0021] Pressure gauge 11 is located at the front end of valve B12.

[0022] Before assembling the cold-end system, reactor 1 is hoisted into the heating device and connected to flange 3. A sealing gasket 2 is placed between the lower flange of reactor 1 and flange 3. The inlet pipe 8 connects to the waste heat pipe of the reduction production system. Heat enters through the inlet pipe 8 and exits through the vent pipe 10. After venting for half an hour, when the temperature reading on the temperature measuring tube 6 is ≥120℃, valve B12 is closed. When the pressure gauge 11 reads 20 kPa, valve A9 is closed and maintained for 1 hour. The moisture adhering to the reactor will evaporate, achieving reactor drying.
