Description

Technical Field

[0001] The utility model relates to the technical field of acid decomposition equipment, in particular to a tantalum-cobalt alloy powder acid decomposition device. Background Art

[0002] Acid hydrolysis is also called acid dissolution. It is a wet process for decomposing mineral raw materials to produce inorganic products. Acid hydrolysis equipment includes mechanical stirring tank reactor, air bubbling tank reactor, rotary drum reactor, plate leaching tower, thickening leaching device and spiral leaching device.

[0003] The existing alloy powder tends to float on the surface of the acid solution when added to the pickling equipment for acid hydrolysis, which increases the time required for complete acid hydrolysis of the alloy powder. Therefore, a tantalum-cobalt alloy powder acid hydrolysis device is needed to enable the alloy powder to be completely integrated into the acid solution during acid hydrolysis, thereby improving the acid hydrolysis efficiency. Utility Model Content

[0004] To this end, the utility model provides a tantalum-cobalt alloy powder acid decomposition device, which solves the problem that the alloy powder is easily floated on the surface of the acid decomposition liquid when added into the pickling equipment for acid decomposition through the acid decomposition stirring mechanism.

[0005] In order to achieve the above object, the utility model provides the following technical solutions: a tantalum-cobalt alloy powder acid decomposition device, comprising an acid decomposition tank, an inner tank is fixedly provided inside the acid decomposition tank, a circulation tank is provided inside the inner tank, and an acid decomposition stirring mechanism is provided inside the acid decomposition tank;

[0006] The acidolysis stirring mechanism includes a transmission rod, which is arranged inside the acidolysis tank. The external fixed sleeve of the transmission rod is provided with a spline shaft, the external sleeve of the spline shaft is provided with a spline sleeve, and the external side of the spline sleeve is provided with two stirring components. The stirring component includes a connecting rod, which is fixedly connected to the spline sleeve, one end of the connecting rod is provided with a slot roller, the external fixed sleeve of the connecting rod is provided with a fixing sleeve, and the bottom of the fixing sleeve is fixedly connected with a stirring blade.

[0007] Preferably, a base is fixedly provided at the bottom of the acid hydrolysis tank.

[0008] Preferably, an alloy powder inlet and an acidolysis liquid inlet are fixedly connected to the outside of the acidolysis tank, and a discharge outlet is fixedly connected to the bottom of the acidolysis tank.

[0009] Preferably, a top cover is fixedly connected to the top of the acid hydrolysis tank.

[0010] Preferably, a motor is fixedly connected to the top of the top cover, and an output end of the motor is fixedly connected to the top of the transmission rod.

[0011] Preferably, the top of the transmission rod passes through the top cover and is connected to the top cover via a bearing, and the bottom of the transmission rod is connected to the bottom of the acid hydrolysis tank via a bearing.

[0012] Preferably, the spline sleeve is arranged outside the spline shaft and is connected to the spline shaft through a spline pair.

[0013] Preferably, one end of the slot roller is connected to the connecting rod via a bearing, and the other end of the slot roller extends into the circulation groove and is slidably connected to the circulation groove.

[0014] The utility model embodiment has the following advantages:

[0015] 1. The connecting rod drives the stirring blade to move synchronously when working, so that the stirring blade stirs the tantalum-cobalt alloy powder and the acid solution. At the same time, the stirring blade can move up and down during stirring, which accelerates the tantalum-cobalt alloy powder on the surface of the acid solution to sink into the acid solution, and prevents the tantalum-cobalt alloy powder from floating on the surface of the acid solution and affecting the acid solution efficiency.

[0016] 2. When the connecting rod rotates, the slot roller is driven to slide along the circulation groove. By cooperating with the circulation groove trajectory, the slot roller drives the connecting rod to move longitudinally. The movement of the connecting rod drives the spline sleeve to slide longitudinally along the spline shaft. The spline pair connection between the spline sleeve and the spline shaft enables the spline shaft to drive the spline sleeve to rotate without affecting the sliding of the spline sleeve along the spline shaft, thereby preventing the spline sleeve from getting stuck while moving longitudinally while rotating.

[0027] In this embodiment, in order to prevent the alloy powder from floating on the surface of the acidolysis solution, the spline shaft 11 is rotated by the transmission rod 10, and the spline shaft 11 rotates through the spline sleeve 12 to drive the connecting rod 13 to rotate, and the connecting rod 13 rotates through the fixed sleeve 15 to rotate the stirring blade 16, and the stirring blade 16 rotates to stir and mix the tantalum-cobalt alloy powder and the acidolysis solution, so that the tantalum-cobalt alloy powder is more quickly integrated into the acidolysis solution, thereby improving the acidolysis efficiency. At the same time, when the connecting rod 13 rotates, the slot roller head 14 is driven to slide along the circulation groove 7, and the slot roller head 14 drives the connecting rod 13 to move longitudinally through the cooperation with the trajectory of the circulation groove 7, so that the stirring blade 16 can move up and down when stirring the tantalum-cobalt alloy powder and the acidolysis solution, thereby accelerating the tantalum-cobalt alloy powder on the surface of the acidolysis solution to sink into the acidolysis solution, thereby preventing the tantalum-cobalt alloy powder from floating on the surface of the acidolysis solution and affecting the acidolysis efficiency.

[0028] Among them, in order to achieve the purpose of adding the substances required for acidolysis, the present device is implemented by the following technical scheme: a base 2 is fixedly provided at the bottom of the acidolysis tank 1, an alloy powder inlet 3 and an acidolysis liquid inlet 4 are respectively fixedly connected to the outside of the acidolysis tank 1, and a discharge port 5 is fixedly connected to the bottom of the acidolysis tank 1. The acidolysis liquid is added into the acidolysis tank 1 through the acidolysis liquid inlet 4, and the tantalum-cobalt alloy powder is added into the acidolysis tank 1 through the alloy powder inlet 3. After the acidolysis is completed, the powder is discharged from the outside of the acidolysis tank 1 through the discharge port 5;

During acidolysis stirring, the motor 9 is started, and the motor 9 rotates through the transmission rod 10 to rotate the spline shaft 11, and the spline shaft 11 rotates through the spline sleeve 12 to drive the connecting rod 13 to rotate, and the connecting rod 13 rotates through the fixed sleeve 15 to rotate the stirring blade 16, and the stirring blade 16 rotates to stir and mix the tantalum-cobalt alloy powder and the acidolysis solution, so that the tantalum-cobalt alloy powder is more quickly integrated into the acidolysis solution, thereby improving the acidolysis efficiency. At the same time, when the connecting rod 13 rotates, it drives the slot roller 14 to slide along the circulation groove 7, and through the matching with the trajectory of the circulation groove 7 The slot roller 14 drives the connecting rod 13 to move longitudinally, and the movement of the connecting rod 13 drives the spline sleeve 12 to slide longitudinally along the spline shaft 11. The spline sleeve 12 is connected to the spline shaft 11 by the spline pair, so that the spline shaft 11 can drive the spline sleeve 12 to rotate, and at the same time, it does not affect the sliding of the spline sleeve 12 along the spline shaft 11, thereby preventing the spline sleeve 12 from getting stuck while rotating and moving longitudinally.
