Description

Technical Field

[0001] This utility model relates to the field of anhydrous aluminum trichloride production technology, and in particular to an electric heating furnace for the production of anhydrous aluminum trichloride. Background Technology

[0002] The traditional production method for aluminum trichloride is the aluminum ingot melting method, which involves sending molten high-purity aluminum ingots into a closed chlorination furnace to react with chlorine gas to produce aluminum trichloride, which is then collected after condensation.

[0003] A search revealed a public disclosure (announcement) number: CN209910382U, which discloses a furnace structure for the production of anhydrous aluminum trichloride. This structure relates to the field of anhydrous aluminum trichloride production technology and includes a refractory casting layer with reinforced fibers embedded within it. An insulation layer is located outside the refractory casting layer, and a circulating refrigerant jacket is located outside the insulation layer. This utility model provides a simple furnace structure for the production of anhydrous aluminum trichloride, extending the furnace's service life and allowing for heat recovery and reuse, thus reducing energy waste.

[0004] Although the above solution has a simple structure, extends the service life of the furnace body, and allows for heat recovery and utilization to reduce energy waste, during the reaction heating process, some molten aluminum will adhere to the inner wall of the furnace body, resulting in a decrease in heat transfer efficiency and a reduction in production efficiency. Therefore, we propose an electric heating furnace for the production of anhydrous aluminum trichloride. Utility Model Content

[0005] The main purpose of this utility model is to provide an electric heating furnace for the production of anhydrous aluminum trichloride. By setting up a stirring unit and a heating unit, it solves the problem that aluminum in a partially molten state will adhere to the inner wall of the furnace body during the reaction heating process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric heating furnace for the production of anhydrous aluminum trichloride includes a main unit, a stirring unit and a heating unit disposed inside the main unit, and a conveying unit disposed on the surface of the main unit.

[0008] The stirring unit includes a rotating shaft movably disposed inside the main unit, a drive motor installed at the input end of the rotating shaft, a stirring rod installed on the side wall of the rotating shaft, and a cleaning component disposed on the side of the rotating shaft;

[0009] The heating unit includes an insulation layer installed on the side wall of the main unit, a heat transfer layer installed on the inner side wall of the main unit, a heating groove opened on the main unit, and a heating column installed inside the heating groove.

[0010] Preferably, the main body unit includes an inclined cylindrical body and a support base installed at the bottom of the inclined cylindrical body.

[0011] Preferably, the main body unit further includes a feeding trough opened at the top of the inclined cylinder, and a sealing cover installed inside the feeding trough.

[0012] Preferably, there are several stirring rods, and the several stirring rods are arranged at equal intervals, and each stirring rod is provided with filter holes.

[0013] Preferably, the cleaning component includes a connecting rod mounted on the side wall of the rotating shaft, and a cleaning plate mounted on the end of the connecting rod.

[0014] Preferably, the conveying unit includes a gas injection pipe installed at the input end of the inclined cylinder, a condenser pipe installed at the output end of the inclined cylinder, and a discharge component disposed at the end of the inclined cylinder.

[0015] Preferably, the discharge component includes a discharge pipe installed at the output end of the inclined cylinder, and a regulating valve movably installed inside the discharge pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the addition of a stirring unit and a heating unit, when aluminum trichloride reaction heating is required, the heating column is energized to heat the inside of the inclined cylinder, and chlorine gas is injected into the inclined cylinder through a gas injection pipe, reacting with the molten aluminum inside. The resulting aluminum trichloride gas can be output and captured through a condenser. During the aluminum trichloride reaction heating, the drive motor drives the rotating shaft to rotate, which in turn drives the stirring rod to rotate synchronously, thereby accelerating the gas flow and increasing the reaction rate. During the rotation of the rotating shaft, the connecting rod can drive the cleaning plate to remove the aluminum adhering to the inner wall of the inclined cylinder, thus preventing aluminum from adhering to the inner wall of the furnace, ensuring the heat transfer effect of the electric heating furnace, and thereby improving production efficiency.
