Technical Field

[0001] The present invention relates to the technical field of alumina seed crystal decomposition equipment, in particular to a device for accelerating the formation of alumina seed crystals for decomposition. Background Art

[0002] Seed formation is a critical step in the alumina decomposition process. Traditional seeding equipment can suffer from issues such as poor stirring, uneven seed addition, difficult temperature control, and imprecise gas stirring and feed control. Forming seeds for alumina decomposition typically requires precipitation of solute from the solution. However, traditional stirring methods may not effectively create the uniform environment required for seed formation, and lack effective methods for seed addition and reaction temperature control, impacting the efficiency and quality of seed formation.

[0003] In order to solve at least part of the above problems, a device for accelerating the formation of seeds for decomposition of aluminum oxide is proposed. Summary of the Invention

[0004] The present invention provides a device for accelerating the formation of seed crystals for the decomposition of aluminum oxide. This device utilizes a unique air intake stirring section. A motor drives a drive rod, which in turn drives a second bevel gear to rotate, thereby driving the linkage of a runner, a cam shaft, a straight groove rod, and a moving rod. This causes the piston block of the piston assembly to move up and down within the piston cylinder, thereby achieving the stirring and air intake functions of the air intake stirring rod. When the piston block moves upward, air is inhaled, and when it moves downward, the gas is discharged into the aluminum electrolyte in the reaction tank. Simultaneously, the rotation of the stirring teeth can break up generated bubbles, strengthen the contact between the electrolyte and air, effectively promote the precipitation of solutes in the solution to form seed crystals, and improve stirring efficiency and the speed of seed crystal formation.

[0006] The air intake stirring part includes an air intake stirring rod, a piston assembly, an air intake pipe, a moving rod, a support ring, a rotating wheel, a cam, a straight groove rod and a second bevel gear. The lower side of the support plate is rotatably connected to the central axis of the driving rod, and the two ends of the driving rod are respectively rotatably connected to the central axis of the second bevel gear. The central axis of each second bevel gear is respectively fixedly connected to the center of the rotating wheel. The cam is fixed at the edge position of one side of each rotating wheel. Each cam is respectively arranged in the slide groove of the straight groove rod, and each cam matches the slide groove of the straight groove rod.

The middle and lower part of the piston cylinder of the piston assembly is fixedly connected to the air intake pipe, and the lower end of the piston cylinder of the piston assembly is fixedly connected to the air intake stirring rod.

[0007] As a further limitation of the present technical solution, the lower end of the air inlet stirring rod is provided with a plurality of evenly arranged stirring teeth.

[0008] As a further limitation of the present technical solution, the second bevel gear meshes with the first bevel gear, the first bevel gear is fixed on the lower side of the support plate, and the central axis of the drive rod passes through the center of the first bevel gear.

[0009] As a further limitation of the present technical solution, it further includes a driving module, the driving module is connected to the driving rod, the driving module is a motor, the motor is fixed to the upper side of the support plate, and the output shaft of the motor is fixed to the central axis of the driving rod.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] This equipment utilizes a unique air-intake stirring section.

[0019] The lifting module (electric push rod) installed on the base can control the lifting and lowering of the air intake stirring part. The height of the air intake stirring part can be adjusted according to actual needs, so as to better adapt to the stirring requirements of different reaction stages and different reaction amounts.

[0020] A one-way air inlet is provided at the connection position between the air intake pipe and the piston cylinder of the piston assembly to ensure that air can only be sucked into the piston cylinder from the air intake pipe, but cannot enter the air intake pipe from the piston cylinder, thereby ensuring the unidirectionality and stability of the air intake and avoiding the adverse effects of gas backflow on the reaction.

[0030] The lower end of the air inlet stirring rod 901 is provided with a plurality of evenly arranged stirring teeth.

[0031] The second bevel gear 909 meshes with the first bevel gear 7 . The first bevel gear 7 is fixed to the lower side of the support plate 2 . The central axis of the driving rod 101 passes through the center of the first bevel gear 7 .

[0032] As a further limitation of the present technical solution, it further includes a driving module 1, which is connected to the driving rod 101.

When the motor is started, the piston barrel of the piston assembly 902 drives the storage barrel 801 to rotate, and the storage barrel 801 drives the discharge pipe 802 to rotate. Due to the setting of the discharge rod 803, the crystal seeds will be discharged into the reaction tank 401 during the rotation of the discharge pipe 802.

[0037] A heating wire 6 is provided in the reaction tank 401 . The heating wire 6 is electrically connected to a power source and a switch and is used to heat the reaction tank 401 .

[0048] During the stirring and air intake process, the up and down movement of the piston block causes the gas to be sucked into the piston cylinder from the air intake pipe 903 and discharged from the lower end outlet of the air intake stirring rod 901 into the aluminum electrolyte in the reaction tank 401. The stirring teeth break up the generated bubbles and drive the contact between the electrolyte and the air, accelerating the precipitation and formation of crystal seeds.
