Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to a hydrometallurgical stirrer capable of optimizing an internal flow field. Background Art

[0002] In the hydrometallurgical process, fixed materials need to be placed in solution for reaction. Due to the large difference in the sealing of reactants, materials with higher density are easily gathered near the inner wall of the stirring container under the centrifugal action in traditional stirring equipment. Although stirring can speed up the reaction rate, the transmission stirring mechanism will make the flow direction of the solution tend to be stable. Under the action of centrifugation, the solution will cause the solid matter to be obviously concentrated, reducing the contact area of ​​the reactive substances, and the reaction rate in the later stage will decrease instead. Utility Model Content

[0005] As a preference, the guide plate has an arc-shaped cross-section and extends in an arc direction. The extension arc of the guide plate is horizontal, so as to prevent the guide plate from being subjected to unnecessary vertical force.

[0006] Preferably, the middle portion of the guide plate is fixedly connected to the swing shaft, and the swing shaft is further provided with a convection hole located inside the arc of the guide plate, through which the transport liquid flows, thereby further reducing the impact force on the swing shaft.

[0007] Preferably, there are several guide plates on each of the swing shafts, and the guide plates are equidistantly arranged along the axis of the swing shaft, so that the flow direction of the liquid flow can be changed at different heights of the stirring tank.

[0009] Preferably, the cross-section of the paddle is arc-shaped and also extends in the arc direction. One end of the paddle is fixedly connected to the outer side surface of the transmission shaft. The paddle is equidistantly arranged along the circumference and axial direction of the transmission shaft, which is conducive to dispersing resistance.

[0010] Preferably, a main shaft hole is provided at the top of the mixing tank for the transmission shaft to pass through, a main shaft sleeve is fixedly connected to the inner bottom surface of the mixing tank, and is suitable for cooperating with the lower end of the transmission shaft to form a rotating pair, and a plurality of secondary shaft holes equidistantly arranged around the main shaft hole are also provided at the top of the mixing tank for the swing shaft to pass through, and a secondary shaft sleeve is fixedly connected to the bottom surface of the mixing tank, and is suitable for cooperating with the lower end of the swing shaft to form a rotating pair to ensure the stability of the upper and lower ends of the shaft body.

The lower end of the inner gear ring has an inner embedded edge, which is suitable for cooperating with the ring groove to form a rotating pair. The upper end of the inner embedded edge has a shift ring. The upper surface of the stirring tank is also fixedly connected to a pin ring. There are several pin rings and they are equidistantly arranged around the axis of the inner gear ring. The shift ring is kept stable in position relative to the shift ring by a locking member, thereby ensuring the stability of the angle of the guide plate after adjustment.

[0012] Preferably, the locking member includes a pin shaft, a handle is fixedly connected to the upper end of the pin shaft, the shift ring is provided with a pin hole, and the pin shaft is suitable for passing through the pin hole and engaging with any one of the pin rings, thereby limiting the angle of the reversing assembly relative to the constraint ring.

[0015] (1) By setting an angle-adjustable guide plate structure in the stirring tank, the rotating liquid flow is provided with resistance that deviates from the original direction of movement, so that the liquid flow generates a flow component along the radial direction of the stirring tank, so that the reactants in the middle exchange positions with the reactants at the edge, thereby increasing the contact efficiency of the reactants. In this way, the rate reduction caused by the centrifugal effect of stirring in the later stage of the reaction is not so obvious;

[0016] (2) By designing a reversing component to control all the flow guide components, not only can the flow guide components be changed synchronously, but the operation process is also more convenient. In combination with the locking structure, the stability of the internal flow field of the mixing tank can be maintained better after adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 1-10The hydrometallurgical agitator that can optimize the internal flow field shown includes a cylindrical agitator 5, which is made of a corrosion-resistant alloy material. The side wall of the agitator 5 is also provided with a feed end 501 near the upper end, through which the raw materials that need to be mixed enter the agitator 5. The bottom of the agitator 5 is provided with a discharge end 502, through which the mixed materials in the agitator 5 are discharged. The bottom surface of the agitator 5 is also fixedly connected to a bracket 7 for allowing the agitator 5 to be suspended at a certain height from the ground.

[0033] The top surface of the stirring tank 5 is provided with a driving mechanism 1, and the driving mechanism 1 includes a motor 101 and a reducer 102 that cooperate with each other. The output end of the motor 101 is connected to the input end of the reducer 102. The motor 101 and the reducer 102 are only fixedly connected to the top surface of the stirring tank 5 by the shell. The output end of the driving mechanism 1, that is, the output end of the reducer 102 extends into the stirring tank 5 and is connected to a stirring component 2. The specific structure of the stirring component 2 includes a transmission shaft 201 fixedly connected to the output end of the reducer 102, and the axis of the transmission shaft 201 is colinear with the axis of the stirring tank 5. The top of the stirring tank 5 is provided with a main shaft The hole 505 is for the transmission shaft 201 to pass through and cooperate to form a rotating pair. The inner bottom surface of the mixing tank 5 is fixedly connected to a main shaft sleeve 506 for cooperating with the lower end of the transmission shaft 201 to form a rotating pair. The outer side surface of the transmission shaft 201 is fixedly connected to a plurality of paddles 202. The cross-section of the paddles 202 is arc-shaped and also extends along the arc direction. The paddles 202 are like a truncated tire outer tire. One end of the paddles 202 is fixedly connected to the outer side surface of the transmission shaft 201, and the paddles 202 are equidistantly arranged along the circumference and axial direction of the transmission shaft 201. In this way, when thrust is applied to the liquid in the mixing tank 5, the force will be more uniform.

[0034] The top of the mixing tank 5 is also movably connected with a plurality of flow guide components 3, which are equidistantly arranged around the axis of the transmission shaft 201. Each flow guide component 3 includes a gear 301 rotatably connected to the mixing tank 5. The lower end of the gear 301 has a swing shaft 302 extending into the mixing tank 5.

The bottom surface of the mixing tank 5 is also fixedly connected with a secondary shaft sleeve 508 for cooperating with the lower end of the swing shaft 302 to form a rotating pair. The outer side surface of the swing shaft 302 is fixedly connected with a flow guide plate 303 for improving the mixing tank 5. The flow direction of the liquid in the mixing tank 5 is changed. Specifically, there are several guide plates 303 on each swing shaft 302. These guide plates 303 are arranged equidistantly along the axial direction of the swing shaft 302, and the cross-section of each guide plate 303 is also arc-shaped. At the same time, the guide plate 303 also extends along the arc direction, which is very similar to an incomplete outer tire. The extension arc of the guide plate 303 is horizontal, so that the liquid flow resistance of the guide plate 303 will not generate a vertical component force. The middle part of the guide plate 303 is fixedly connected to the swing shaft 302. The swing shaft 302 is also provided with a convection hole 304 located on the inner side of the arc of the guide plate 303, through which the transport liquid flows, thereby further reducing the resistance to the liquid passing through the mixing tank 5.

[0035] The top of the mixing tank 5 is also rotatably connected to a reversing assembly 4 for controlling the angle of the flow guide assembly 3, thereby changing the flow field inside the mixing tank 5. The main part of the reversing assembly 4 is an inner gear ring 401, which is meshed with all the gears 301 at the same time, thereby realizing synchronous control of the flow guide assembly 3. The top surface of the mixing tank 5 is fixedly connected to a constraint ring 503, which is coaxial with the transmission shaft 201. A ring groove 504 which is also coaxial with the transmission shaft 201 is formed between the constraint ring 503 and the top surface of the mixing tank 5. The lower end of the inner gear ring 401 has an inner embedded edge 402 with a larger outer diameter, which is used to cooperate with the ring groove 504 to form a rotating pair, thereby ensuring the movement stability of the entire reversing assembly 4. The upper end of the inner embedded edge 402 has a dial ring 40 with a smaller inner diameter. 3, can directly contact with the hand, more convenient to rotate the entire reversing assembly 4, the upper surface of the mixing tank 5 is also fixedly connected with a pin ring 509, there are several pin rings 509, these pin rings 509 are generally only located between adjacent gears 301, and are equidistantly arranged around the axis of the inner gear ring 401, the shifting ring 403 can be kept stable relative to the shifting ring 403 by the locking member 6, the specific structure of the locking member 6 includes a pin shaft 601, the upper end of the pin shaft 601 is fixedly connected with a handle 602, convenient for holding for insertion and extraction operations, the shifting ring 403 is provided with a pin hole 404 running through the upper and lower surfaces, after the pin shaft 601 passes through the pin hole 404 and is plugged into any pin ring 509, the angle of the reversing assembly 4 relative to the constraint ring 503 will be locked.

[0036] Working principle: In the initial state, the arc points in the length direction of the guide plate 303 are located on the axis of the transmission shaft 201, and the paddle 202 drives the solution in the stirring tank 5 to rotate, with the least obstruction from the guide component 3. The flow direction of the solution is similar to that in the traditional stirring equipment, basically maintaining the tangential direction of the circle. Remove the locking piece 6 and rotate the reversing component 4 to allow all the guide components 3 to deflect a certain angle at the same time, and use the locking piece 6 to lock it again. At this time, the arc points in the length direction of all the guide plates 303 deviate from the axis of the transmission shaft 201, and the flowing solution is blocked by the inner wall or outer wall of the guide plate 303. The flow direction of the solution deviates from the tangential direction of the circle, and obvious convection is generated in the radial direction of the inner wall of the stirring tank 5. In this way, the solution at the center of the stirring tank 5 and the solution at the edge will have a more obvious exchange, which can effectively improve the mixing efficiency and reduce the phenomenon that the materials cannot be quickly and fully contacted due to the centrifugal effect.
