Description

Technical Field

[0001] This utility model relates to the technical field of stirring tools in electrolysis workshops, specifically to a liquid stirring device for the electrolytic zinc liquid production process. Background Technology

[0002] In the zinc smelting industry, hydrometallurgical zinc refining processes account for the vast majority of enterprises. The process mainly includes electrolyte preparation and electrolysis. The electrolyte preparation process involves creating the electrolyte solution, and the solubility of the electrolyte within the solution affects the yield and quality of the electrolytic products. During electrolyte preparation, a stirring device is needed to ensure the electrolyte is fully dissolved. If the stirring technology is not properly controlled, excessive stirring can cause leakage of the hydrometallurgical zinc leaching solution. Improper control of the stirring frequency can lead to cooling of the electrolyte, causing blockages in subsequent electrolysis processes and increasing the difficulty of electrolysis. In severe cases, it can paralyze the entire electrolysis system.

[0003] Existing mixing devices generally include: a rotating shaft, blades connected to the rotating shaft, and a motor connected to the rotating shaft to drive the blades to rotate around the rotating shaft. However, this structure has the problem of poor balance during mixing, which causes uneven force on the coupling, thereby increasing the load on the drive motor and increasing the energy consumption of the mixing device. It can be seen that the practicality and durability of this structure are not strong.

[0004] In view of this, this embodiment provides a liquid stirring device for the electrolytic zinc liquid production process. Utility Model Content

[0005] This invention proposes a liquid stirring device for the electrolytic zinc solution production process to solve the technical problems existing in the aforementioned background art.

[0006] The technical solution of this utility model is as follows:

[0007] A liquid stirring device for an electrolytic zinc production process includes a receiving cavity, a rotating shaft, a top plate for mounting the rotating shaft, and a motor driven and connected to the rotating shaft. It also includes a base with a pair of connecting columns fixed on it. The top ends of the connecting columns are connected to the top plate, which has a quadrilateral structure. The rotating shaft and the top plate are connected by a coupling. The rotating shaft includes a double-layered three-bladed impeller, which is connected to a connecting seat on the rotating shaft. The angle between the blades of the upper and lower three-bladed impellers is 30°. The rotating shaft also includes a reduction mechanism, which includes a reduction wheel, a lever reducer, and a belt. The reduction wheel is connected to the rotating shaft, and the belt is fitted onto the reduction wheel and the lever reducer. The lever reducer is connected to the top plate.

[0008] Optionally, the surface of the blade is provided with a PPH plate.

[0009] Optionally, the three blades of the three-bladed propeller are arranged in the vertical direction according to a preset height difference.

[0010] Optionally, the connection between the connector and the shaft is provided with a thread, which is used to engage with the outer surface of the shaft; the direction of the thread is opposite to the direction of rotation of the motor.

[0011] Optionally, the rotating shaft surface further includes detectors, and multiple detectors are provided along the length direction of the rotating shaft. The detectors are signal-connected to the control device.

[0012] Optionally, the blades are arc-shaped or long triangular pyramidal.

[0013] Optionally, a slide bar is provided on the mounting platform below the base, and the slide bar is provided with a threaded hole.

[0014] The principle and beneficial effects of this utility model are as follows:

[0015] In this invention, the top plate for mounting the motor is connected to the base in the horizontal plane via a connecting column to reduce the offset of the motor's rotation center. The motor drives the rotating shaft to rotate, causing the three-bladed impeller connected to the shaft to rotate, thus agitating the electrolyte in the containment cavity. The double-layered three-bladed impeller structure ensures uniform agitation of the electrolyte along the height of the shaft, satisfying the requirement for uniform stirring and reducing the inertial force of the shaft on the connecting seat, maintaining the shaft's balance. Furthermore, this invention includes a reduction mechanism to control the shaft's stop. This reduction mechanism is connected to the shaft via a belt, indirectly controlling the shaft's stop. The lever reducer does not directly act on the shaft; the belt's extensibility maintains the overall balance of the shaft during deceleration and stop. This invention reduces the energy consumption of the motor controlling the shaft's rotation, while also reducing wear and tear on the shaft and its balance caused by the lever reducer, thus improving the overall practicality and durability of the stirring device.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] In the zinc smelting industry, hydrometallurgical zinc refining processes account for the vast majority of enterprises. The process mainly includes a solution preparation step and an electrolysis step. The solution preparation step involves producing the electrolyte, and the solubility of the electrolyte in the electrolyte affects the yield and quality of the electrolytic products. In the solution preparation step, a stirring device is needed to ensure the electrolyte is fully dissolved. If the stirring technology is not properly controlled, excessive stirring can cause leakage of the hydrometallurgical zinc leaching solution. Improper stirring frequency control can lead to electrolyte cooling, causing blockages in subsequent electrolysis processes and increasing the difficulty of electrolysis. In severe cases, it can paralyze the entire electrolysis system. Existing stirring devices generally include a rotating shaft, blades connected to the shaft, and a motor connected to the shaft that drives the blades to rotate around the shaft. However, this structure has problems: poor balance during stirring, resulting in uneven stress on the coupling, which increases the load on the drive motor and increases the energy consumption of the stirring device. Therefore, this structure is not practical or durable. In view of this, this embodiment provides a liquid stirring device for the zinc electrolysis solution preparation process.

[0024] Refer to the instruction manual appendix Figures 1 to 4 As shown, where Figure 1 Only one three-leaf paddle is shown for illustration. Figure 1 The dashed line in the middle indicates the mounting platform of the mounting base.

[0025] This utility model provides a liquid stirring device for the electrolytic zinc liquid production process, including a receiving cavity, a rotating shaft 1, a top plate 2 for mounting the rotating shaft, and a motor 3 driven and connected to the rotating shaft 1. It also includes a base 4, on which a pair of connecting columns 5 are fixed. The top ends of the connecting columns 5 are connected to the top plate 2. The top plate 2 has a quadrilateral structure. The rotating shaft 1 and the top plate 2 are connected by a coupling. The rotating shaft 1 includes a double-layered three-bladed impeller 6, which is connected to a connecting seat on the rotating shaft 1. The angle between the blades of the upper and lower three-bladed impellers 6 is 30°. The rotating shaft 1 also includes a reduction mechanism 7, which includes a reduction wheel 71, a lever reducer 72, and a belt 73. The reduction wheel 71 is connected to the rotating shaft 1, and the belt 73 is fitted onto the reduction wheel 71 and the lever reducer 72. The lever reducer 72 is connected to the top plate 2.

[0026] As described above, in this invention, the top plate 2 on which the motor 3 is mounted is connected to the base 4 in the horizontal plane via a connecting column 5 to reduce the offset of the rotation center of the motor 3; the motor 3 drives the rotating shaft 1 to rotate, causing the three-bladed impeller 6 connected to the rotating shaft 1 to rotate, thus agitating the electrolyte in the containing cavity. The double-layered three-bladed impeller 6 structure ensures that the electrolyte is uniformly agitated along the height direction of the rotating shaft 1, satisfying the requirement of uniform stirring and reducing the inertial force of the rotating shaft 1 on the connecting seat, maintaining the balance of the rotating shaft 1. Furthermore, this invention includes a reduction mechanism 7, which controls the rotation of the rotating shaft 1 to stop. For example... Figure 2 As shown, the reduction mechanism 7 is connected to the rotating shaft 1 via a belt 73, thus indirectly controlling the rotation of the rotating shaft 1. The lever reducer 72 does not directly act on the rotating shaft 1; instead, it utilizes the extensibility of the belt 73 to maintain the overall balance of the rotating shaft 1 during deceleration and shutdown. This invention reduces the energy consumption of the motor 3 that controls the rotation of the rotating shaft 1, while also reducing the wear and tear on the rotating shaft 1 caused by the lever reducer 72 and its disruption of the rotating shaft 1's balance, thereby improving the overall practicality and durability of the stirring device.

[0027] In this embodiment, the surface of the aforementioned propeller blade is provided with a PPH plate. The PPH plate is an abbreviation for high-performance polypropylene (Polypropylene Homopolymer), and it serves as an anti-corrosion layer for the propeller blade, preventing corrosion during use and thus affecting the electrolysis process or the purity of the electrolytic products. Of course, the use of other anti-corrosion materials similar to PPH in this invention's structure is simply a substitution of similar materials and is within the protection scope of this invention. The aforementioned receiving cavity is the receiving cavity of the electrolytic cell for holding the electrolyte, and can be cylindrical, cubic, or other structures; this embodiment does not impose specific limitations on this.

[0028] In addition, such as Figure 3As shown, the angle between the blades of the upper three-blade paddle 6 and the lower three-blade paddle 6 is 30°. The vertical projection of the upper three-blade paddle 6 and the lower three-blade paddle 6 shows that the angle between the blades of the upper and lower three-blade paddle 6 is equal, both being 30°, so that the blades are evenly distributed and the uniformity of stirring is increased during stirring.

[0029] Additionally, refer to Figure 2 As shown, in this embodiment, the lever reducer 72 in the deceleration mechanism 7 is mounted on the top plate 2. Its output end is connected to the gear. The gear of the lever reducer 72 is connected to the deceleration wheel 71 on the rotating shaft 1 by the belt 73, which indirectly controls the rotating shaft 1 to stop rotating. The lever reducer 72 does not directly act on the rotating shaft 1, and the extensibility of the belt 73 is effectively utilized to maintain the overall balance of the rotating shaft 1 when it decelerates and stops.

[0030] Additionally, it should be noted that in this embodiment, the coupling is used as the fulcrum, and the sum of the torques between the two connecting seats and the coupling is equal to the torque between the motor 3 and the coupling. This design ensures that the coupling is subjected to uniform force, maintaining the balance of the motor 3's stirring action. The specific calculated torque value is related to the distance between the two connecting seats and the coupling, as well as parameters such as the torque of the motor 3, the weight of the connector, the weight of the three-bladed propeller 6, and the radius of rotation. This embodiment does not impose specific limitations on these parameters.

[0031] It should be noted that the three blades of the aforementioned three-bladed propeller 6 are arranged vertically with a predetermined height difference. The propeller blades in this utility model include... Figure 4 The arc-shaped structure shown also includes Figure 3 The geometric structure shown is similar to a three-cone, in which the three blades of the same layer have a predetermined height difference in the vertical direction, so that the blades can stir the electrolyte of three different layers after they are rotated, thereby increasing the uniformity of stirring.

[0032] In some embodiments, the connecting seat for the aforementioned three-bladed impeller 6 is threaded at the connection point with the rotating shaft 1. The thread is used to engage with the outer surface of the rotating shaft 1; the direction of the thread is opposite to the direction of rotation of the motor 3. In this embodiment, if the motor 3 controlling the rotating shaft 1 rotates forward, then when the motor 3 rotates in reverse, the connecting seat moves up / down along the rotating shaft 1, thereby facilitating the adjustment of the spacing between two adjacent three-bladed impellers 6. When the volume of electrolyte in the containment cavity changes, the rotating shaft 1 does not need to be replaced; the three-bladed impellers 6 can be directly controlled to move up or down to adjust their spacing and the distance between the bottom three-bladed impeller 6 and the bottom surface of the containment cavity to accommodate different volumes of electrolyte. This embodiment further improves the practicality of the stirring device.

[0033] In other embodiments, the aforementioned rotating shaft 1 surface further includes detectors, with multiple detectors arranged along the length of the rotating shaft 1, and the detectors are signal-connected to a control device. In this embodiment, the detectors include detectors for detecting electrolyte solubility, detectors for detecting electrolyte volume, detectors for detecting ion solubility in the electrolyte, etc. Appropriate detectors can be set according to the parameters of the electrolysis products and the electrolyte; this embodiment does not impose specific limitations on this.

[0034] In summary, this invention optimizes the number of mixing layers and the structure of the reducer, thereby reducing the power consumption of the mixing system, saving production costs, and improving the stability and balance of the mixing device.

[0035] In some embodiments, a sliding rod is provided on the mounting platform below the base 4, and the sliding rod has a threaded hole. The base 4 and the sliding rod are bolted together. When it is necessary to adjust the position of the stirring device, the bolt can be released to push the base 4 to move along the sliding rod, so as to accommodate the stirring of electrolyte in different areas of the electrolyte container, further improving the practicality of the stirring device.

[0036] Finally, this utility model provides a liquid stirring device for the electrolytic zinc liquid production process, including a receiving cavity, a rotating shaft 1, a top plate 2 for mounting the rotating shaft 1, and a motor 3 connected to the rotating shaft for driving. It also includes a base 4, on which a pair of connecting columns 5 are fixed. The top of the connecting columns 5 is connected to the top plate 2. The top plate 2 has a quadrilateral structure. The rotating shaft 1 and the top plate 2 are connected by a coupling. The rotating shaft 1 includes a double-layered three-bladed blade 6. The three-bladed blade 6 is connected to the connecting seat on the rotating shaft 1. The included angle between the blades of the upper three-bladed blade 6 and the lower three-bladed blade 6 is 30°. The rotating shaft 1 also includes a reduction mechanism 7, which includes a reduction wheel 71, a rod reducer 72, and a belt 73. The reduction wheel 71 is connected to the rotating shaft 1. The belt 73 is sleeved on the reduction wheel 71 and the rod reducer 72. The rod reducer 72 is connected to the top plate 2. This invention reduces the energy consumption of the motor 3 that controls the rotation of the shaft 1, while also reducing the wear and tear on the shaft 1 caused by the shaft reducer 72 and its disruption of the shaft 1's balance, thus improving the overall practicality and durability of the stirring device.
