[0002] Zinc alloys are alloys composed of zinc as a base and other elements added. Commonly added alloying elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. In the process of melting zinc alloys, the zinc alloy blocks thrown into the furnace need to be stirred so that the zinc alloy blocks can gradually melt and be evenly mixed with the zinc alloy solution.

[0003] For example, patent CN213335608U discloses a stirring device for zinc alloy production, including a fixed box, a stirring shaft rotatably mounted inside the fixed box, a stirring motor fixedly mounted on the top of the fixed box, the output shaft of the stirring motor connected to the stirring shaft, stirring rods evenly fixed on the stirring shaft, a stirring wheel fixedly mounted at the bottom end of the stirring shaft, a feed inlet at the top of the fixed box, a fixed base fixedly mounted below the fixed box, the fixed base connected to the fixed box via shock-absorbing legs, a receiving container at the top of the fixed base, and a discharge outlet at the bottom of the fixed box. The stirring rods and stirring wheel can thoroughly stir the zinc alloy solution.

[0004] This type of stirring device can only perform single circumferential stirring during the stirring process. However, single circumferential stirring is prone to causing stratification, which causes the zinc alloy block to move regularly in the solution, reducing the stirring effect. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that the existing stirring device can only perform single circumferential stirring during the stirring process. However, single circumferential stirring is prone to forming stratification, which causes the zinc alloy block to move regularly in the solution, thus reducing the stirring effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a stirring and mixing device for zinc alloy production, comprising: Mixing tank; A circumferential stirring mechanism includes: a rotating shaft, stirring blades, and a driving component; the rotating shaft is rotatably mounted inside the stirring tank, one end of each stirring blade is vertically fixed to the rotating shaft, and the driving component drives the rotating shaft to rotate; and A radial stirring mechanism includes: a sliding stirring blade and a driving assembly; the sliding stirring blade is arranged perpendicularly to the stirring blade, and the sliding stirring blade is slidably connected to the stirring blade in the length direction of the stirring blade; the driving assembly can drive the sliding stirring blade to slide.

[0007] Preferably, the driving assembly includes: a sliding rod and a friction wheel; the sliding rod is slidably inserted into the rotating shaft along the sliding direction of the sliding stirring plate; and one end of the sliding rod is fixedly connected to the sliding stirring plate; the friction wheel is rotatably mounted on the rotating shaft, and the axis of the friction wheel is perpendicular to the sliding rod, and the friction wheel abuts against the sliding rod; the radial stirring mechanism further includes: a transmission assembly; the transmission assembly can drive the friction wheel to rotate.

[0008] Preferably, the stirring blades, drive assembly, and sliding stirring plate are arranged at intervals in the axial direction of the rotating shaft; the radial stirring mechanism further includes a connecting assembly, which includes a transmission belt; the transmission belt connects the plurality of friction wheels so that the plurality of friction wheels rotate synchronously.

[0009] Preferably, the connecting assembly further includes: a tensioning pulley; the tensioning pulley is rotatably mounted on the rotating shaft, and the tensioning pulley is connected to the transmission belt to tension the transmission belt; and the tensioning pulley is located on the outside of the transmission belt.

[0010] Preferably, the transmission assembly includes: a first bevel gear, a second bevel gear, a transmission gear, and an internal gear ring; the first bevel gear and the second bevel gear are rotatably mounted on the rotating shaft, and the first bevel gear and the second bevel gear mesh with each other; the first bevel gear rotates synchronously with the friction wheel; the transmission gear rotates synchronously with the second bevel gear; the internal gear ring is fixedly mounted on the mixing tank, and the internal gear ring is coaxially arranged with the rotating shaft, and the internal gear ring meshes with the transmission gear.

[0012] Preferably, the stirring blade is slidably inserted into the sliding stirring plate.

[0013] Preferably, the lower end of the mixing tank is tapered.

[0014] Compared with the prior art, the present invention has at least the following advantages: In this invention, a drive unit drives a rotating shaft to rotate, which in turn drives a stirring blade to rotate circumferentially in the mixing tank, thereby agitating the zinc alloy block and solution within the mixing tank circumferentially. Then, a drive assembly drives a sliding stirring plate to slide along the length of the stirring blade, which in turn agitates the zinc alloy block and solution within the mixing tank radially. Radial agitation promotes the reciprocating movement of the solution from the center to the tank wall. Combined with the tangential shear force of the circumferential flow, this creates complex turbulence within the mixing tank, causing irregular movements of the zinc alloy block, thus enhancing the agitation effect within the mixing tank.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] See Figures 1-3 The present invention provides an embodiment of a mixing device for zinc alloy production, comprising: a mixing tank 1, a circumferential mixing mechanism 2, and a radial mixing mechanism; the circumferential mixing mechanism 2 includes: a rotating shaft 21, a mixing blade 22, and a driving component 23; the rotating shaft is rotatably installed inside the mixing tank 1, one end of the mixing blade 22 is vertically fixed on the rotating shaft, and the driving component 23 drives the rotating shaft to rotate; the radial mixing mechanism includes: a sliding mixing plate 3 and a driving assembly 4; the sliding mixing plate 3 is arranged perpendicularly to the mixing blade 22, and the sliding mixing plate 3 is slidably connected to the mixing blade 22 along the length direction of the mixing blade 22; the driving assembly 4 can drive the sliding mixing plate 3 to slide; furthermore, the lower end of the mixing tank 1 is tapered; the discharge port is located at the smallest end of the tapered shape, thereby facilitating the discharge of zinc alloy liquid from the mixing tank 1.

[0022] In specific implementation, the driving component 23 can be a motor; the driving component 23 drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade 22 to rotate in the circumferential direction of the mixing tank 1, thereby stirring the zinc alloy block and solution in the circumferential direction; then the driving component 4 drives the sliding stirring plate 3 to slide in the length direction of the stirring blade 22, thereby stirring the zinc alloy block and solution in the mixing tank 1 in the radial direction through the sliding stirring plate 3. Radial stirring can promote the reciprocating movement of the solution from the center to the tank wall. Combined with the tangential shear force of the circumferential flow, the solution in the mixing tank 1 forms a complex turbulence, which can drive the irregular movement of the zinc alloy block, thus enhancing the stirring effect in the mixing tank 1.

[0023] See Figures 1-3 In other embodiments, the drive assembly 4 includes: a sliding rod 41 and a friction wheel 42; the sliding rod 41 is slidably inserted into the rotating shaft along the sliding direction of the sliding stirring plate 3; and one end of the sliding rod 41 is fixedly connected to the sliding stirring plate 3; the friction wheel 42 is rotatably mounted on the rotating shaft, and the axis of the friction wheel 42 is perpendicular to the sliding rod 41, and the friction wheel 42 abuts against the sliding rod 41; the radial stirring mechanism further includes: a transmission assembly 5; the transmission assembly 5 can drive the friction wheel 42 to rotate.

[0024] In specific implementation, the transmission component 5 can be a motor; when the transmission component 5 is activated, it drives the friction wheel 42 to rotate, and the friction wheel 42 drives the sliding rod 41 to slide through the friction between it and the sliding rod 41, thereby driving the sliding stirring plate 3 to move, so as to realize the radial stirring of the zinc alloy block and solution in the stirring tank 1.

[0025] See Figures 1-3 In other embodiments, multiple stirring blades 22, drive components 4, and sliding stirring plates 3 are spaced apart in the axial direction of the rotating shaft; the radial stirring mechanism also includes a connecting component 6, which includes a transmission belt 61; the transmission belt 61 connects multiple friction wheels 42 so that the multiple friction wheels 42 rotate synchronously. In specific implementation, the transmission belt 61 is sleeved on multiple friction wheels 42, so that the transmission component 5 drives one of the friction wheels 42 to rotate, thereby driving the transmission belt 61 to move, thereby driving the remaining friction wheels 42 to rotate through friction, thus driving multiple sliding stirring plates 3. Moreover, through the arrangement of multiple sliding stirring plates 3 and stirring blades 22, multiple positions in the stirring tank 1 can be stirred, thereby improving the stirring effect of the zinc alloy block and solution in the stirring tank 1.

[0026] See Figures 1-3In other embodiments, the connecting assembly 6 further includes a tensioning wheel 62; the tensioning wheel 62 is rotatably mounted on a rotating shaft and is connected to the transmission belt 61 to tension the transmission belt 61; and the tensioning wheel 62 is located on the outside of the transmission belt 61. By setting the tensioning wheel 62, the transmission belt 61 can be tensioned to prevent loosening between the transmission belt 61 and the friction wheel 42. Furthermore, by placing the tensioning wheel 62 on the outside of the transmission belt 61, the wrap angle between the transmission belt 61 and the friction wheel 42 can be changed, ensuring sufficient friction between the transmission belt 61 and the friction wheel 42 to drive the friction wheel 42 to rotate. Specifically, the number of tensioning wheels 62 is set according to the number of friction wheels 42 to ensure a suitable wrap angle between the friction wheel 42 and the transmission belt 61.

[0027] See Figures 1-3 In other embodiments, the transmission assembly 5 includes: a first bevel gear 51, a second bevel gear 52, a transmission gear 53, and an internal gear ring 54; the first bevel gear 51 and the second bevel gear 52 are rotatably mounted on the rotating shaft, and the first bevel gear 51 and the second bevel gear 52 mesh with each other; the first bevel gear 51 rotates synchronously with the friction wheel 42; specifically, the friction wheel 42 rotates synchronously via a belt drive 61; the transmission gear 53 rotates synchronously with the second bevel gear 52; specifically, the second bevel gear 52 rotates synchronously with the transmission gear 53 via a shaft; the internal gear ring 54 is fixedly mounted on the mixing tank 1, and the internal gear ring 54 is coaxially arranged with the rotating shaft, and the internal gear ring 54 meshes with the transmission gear 53.

[0028] See Figures 1-3 In other embodiments, the angle between the stirring blade 22 and the rotating shaft is set between 30° and 60°. This allows the stirring blade 22 to apply a force in both the vertical and horizontal directions to the mixing tank 1 when it rotates, effectively pushing the liquid upwards and further enhancing the stirring effect within the mixing tank 1. Specifically, the angle between the stirring blade 22 and the rotating shaft can be 30°, 35°, 40°, 45°, 50°, 55°, or 60°.

[0029] See Figures 1-3 In another embodiment, the stirring blade 22 is slidably inserted onto the sliding stirring plate 3. This allows the sliding stirring plate 3 to scrape off any residual zinc alloy liquid on the stirring blade 22 as it slides along the stirring blade 22.

[0030] Furthermore, the rotating shaft has a cavity, and the friction wheel 42, the transmission belt 61 and the tension wheel 62 are all located in the cavity to protect the friction wheel 42, the transmission belt 61 and the tension wheel 62; the transmission assembly 5 and the drive component 23 are located on the outside of the mixing tank to protect the transmission assembly 5 and the drive component 23.
