Description

Technical Field

[0001] The present invention relates to the technical field of titanium sponge production, and particularly to a forced heat dissipation device for producing titanium sponge by the magnesium thermal reduction method. Background Art

[0002] The magnesium thermal reduction method is the main method for industrial production of titanium sponge. In this method, titanium tetrachloride reacts violently with magnesium to generate titanium sponge. In order to maintain the reduction reaction within the required temperature range, the reaction waste heat must be discharged from the reactor in a timely manner. Otherwise, an over-temperature reaction will occur, resulting in an increase in the impurity content in the product and a decrease in the quality of the titanium sponge product. Traditional heat dissipation methods include natural ventilation and forced ventilation, but these methods have many deficiencies, such as low feeding speed, low single-furnace output, long reduction cycle, rapid aging of heating wires, deformation of the reactor, inaccurate heat dissipation, and poor looseness of titanium sponge. Summary of the Invention

[0003] The present invention aims to provide a novel forced heat dissipation device to solve the problems existing in the prior art, strengthen heat dissipation, reduce equipment aging, and improve the production efficiency and product quality of titanium sponge.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: A forced heat dissipation device for titanium sponge production includes a reactor, a radiator, and a telescopic device. A radiator is arranged in the space between the reactor and the furnace shell. The radiator is provided with a telescopic device for controlling the entry and exit of the radiator. The radiator withdraws from the middle space between the reactor and the furnace shell through the telescopic device, facilitating the charging and discharging of the reactor.

[0005] The beneficial effects of adopting the above technical solutions are as follows: 1. The present invention enhances the heat dissipation effect: By pressing the radiator against the reactor wall and providing radiator sub-channels inside the radiator, the heat dissipation efficiency is improved, the reaction temperature is effectively controlled, and over-temperature reactions are avoided.

[0006] 2. The present invention improves the product quality: Strengthening heat dissipation helps to improve the looseness of the titanium sponge product, reduce the impurity content in the product, and enhance the product quality.

[0007] 3. The present invention extends the equipment life: The design of the radiator avoids cold air directly entering the furnace shell, slows down the aging of heating wires and the deformation of the reactor, and extends the service life of the equipment.

[0008] 4. The present invention optimizes the production efficiency: By optimizing the heat dissipation method, the aspect ratio of the reactor can be appropriately adjusted, reducing the sintering of titanium sponge and improving the production efficiency. Brief Description of the Drawings

[0013] The present invention will be further described in detail below with reference to the accompanying drawings. However, it should not be understood that the scope of the subject matter of the present invention is limited to the following embodiments. Without departing from the above - mentioned technical idea of the present invention, all modifications, substitutions, and changes made according to ordinary technical knowledge and conventional means in the art are included in the scope of the present invention.

[0014] 1. A forced heat dissipation device for titanium sponge production. During the production of titanium sponge, as the reaction progresses, the reaction liquid level continuously rises, and the reaction center zone changes accordingly. The radiator 2 dissipates heat through the main heat dissipation channel 21 and the sub - heat dissipation channel 22, and the heat dissipation area changes with the change of the reaction center. Atomized water can be added to the main heat dissipation channel 21 of the radiator to further enhance the heat dissipation effect. After the reduction is completed, the radiator 2 withdraws from the space between the reactor 1 and the furnace shell through the automatic telescopic device 3, facilitating the charging and discharging of the reactor 1.

[0015] The radiator telescopic device 3 and the radiator 2 work in a long - term high - temperature environment in the furnace. Therefore, materials with high temperature resistance and anti - deformation properties (such as made of high - temperature alloy Inconel 718) need to be selected. In addition, to meet the heating requirements, the size of the radiator 2 needs to be demonstrated according to the actual situation. Slide rails and heating blocks with heating wires can be set in the hollow area of the furnace shell. After the reduction charging is completed, the radiator 2 retracts and slides into the hollow area of the furnace shell to meet the heating requirements during the reduction preparation period.
