[0033] The embodiments of the present application will be described in detail below in combination with the drawings, but the present application can be implemented in various different ways covered and limited by the following.

[0034] Referring to Figures 1-2 The preferred embodiment of the utility model provides a kind of wet leaching device, comprising: hollow and upper end opening's leaching cylinder 1, the cylinder cover 2 for closing the upper opening end of leaching cylinder 1, rotating stirring mechanism 3 for stirring mixing effect.The cylinder cover 2 is covered on the upper opening end of leaching cylinder 1.The rotating stirring mechanism 3 includes the connecting driving portion connected on the cylinder cover 2, and the stirring rod 31 connected with the connecting driving portion, and the stirring rod 31 is inserted into the hollow leaching cavity of leaching cylinder 1, and the connecting driving portion is used to drive the stirring rod 31 to revolve around the periphery of leaching cavity while revolving around its own axis, to sufficiently stir the ore particle and solvent in leaching cavity.

[0035] In the wet leaching device of the utility model, including rotating stirring mechanism 3, rotating stirring mechanism 3 further includes connecting driving portion and stirring rod 31, and stirring rod 31 can revolve around the periphery of leaching cavity while revolving around its own axis under the action of connecting driving portion, to realize the sufficient stirring of the ore particle and solvent in leaching cavity, not only can promote the suspension and uniform dispersion of ore particle in leaching liquid, so that ore particle and leaching liquid can be fully mixed, to further improve the efficiency of leaching, and stirring can also speed up the relative flow of ore particle and leaching liquid, to improve leaching speed, and the upper opening end of leaching cylinder 1 is also provided with cylinder cover 2 for closing the upper opening end, to effectively prevent liquid evaporation, water absorption or reaction with components in air, to further ensure the stability and effectiveness of leaching process, while preventing reagent from being contaminated by external environment.

[0036] Optionally, as Figures 3-4 As shown, connecting driving portion includes driving member 32, revolution realization mechanism 33 and rotation realization mechanism 34.Driving member 32 is connected on the upper surface of cylinder cover 2, and revolution realization mechanism 33 and rotation realization mechanism 34 are respectively connected on the lower surface of cylinder cover 2 and are mutually nested.The power output end of driving member 32 is respectively connected with revolution realization mechanism 33 and rotation realization mechanism 34, and the output end of revolution realization mechanism 33 and rotation realization mechanism 34 is respectively connected with stirring rod 31, to drive revolution realization mechanism 33 to drive stirring rod 31 to revolve around the periphery of leaching cavity while rotation realization mechanism 34 drives stirring rod 31 to revolve around its own axis under the action of driving member 32.

[0037] In this alternative, as Figure 3As shown, the driving member 32 comprises a motor mounting base 321 fixedly arranged on the upper surface of the barrel cover 2, a driving motor 322 arranged on the motor mounting base 321, and a rotating shaft 323 fixedly connected with the output end of the driving motor 322. The rotating shaft 323 extends into the leaching cavity through the barrel cover 2, and the input ends of the revolution realizing mechanism 33 and the rotation realizing mechanism 34 are respectively connected with the rotating shaft 323. In this alternative, the revolution realizing mechanism 33 and the rotation realizing mechanism 34 are respectively connected with the rotating shaft 323, and the rotating shaft 323 is connected with the output end of the driving motor 322. When the driving motor 322 is started, the rotating shaft 323 is driven to rotate, and then the revolution realizing mechanism 33 and the rotation realizing mechanism 34 are respectively driven to move by the rotating shaft 323, so as to realize the revolution and rotation of the stirring rod 31 at the same time, and to sufficiently stir the ore particles and the solvent.

[0038] In this alternative, as shown in Figures 3-4 The revolution realizing mechanism 33 comprises a hollow cylindrical rotating drum 331 with two open ends, a bottom plate 332 fixedly connected with the bottom end opening of the rotating drum 331, and a mounting cylinder 333 fixedly connected with the lower surface of the bottom plate 332. The bottom end of the rotating shaft 323 is fixed with the bottom plate 332, and the mounting cylinder 333 is eccentrically arranged relative to the rotation center of the rotating drum 331. The stirring rod 31 is connected with the mounting cylinder 333, so as to revolve around the rotation center line of the rotating drum 331 under the driving of the mounting cylinder 333. When working, the rotating shaft 323 rotates, and then drives the rotating drum 331 and the bottom plate 332 to synchronously rotate. When the bottom plate 332 rotates, the mounting cylinder 333 is driven to synchronously rotate. Since the mounting cylinder 333 is eccentrically arranged relative to the rotation center of the rotating drum 331, when the mounting cylinder 333 rotates, the stirring rod 31 is driven to revolve around the rotation center line of the rotating drum 331, so as to increase the stirring area of the stirring rod 31, and to make the ore particles and the leaching liquid more sufficiently react.

[0039] In this alternative, as shown in Figures 3-4As shown, the rotation realizing mechanism 34 comprises a fixed cylinder 341 which is hollow and has two ends communicated, a crank 342 which is fixedly sleeved on the outer circle of the rotating rod 323, a mounting support 343 which is fixed on the upper surface of the bottom plate 332, a connecting rod 344 which is vertically arranged in the mounting support 343, and a planetary gear 345 which is fixedly arranged on the outer circle of the connecting rod 344. The upper end of the fixed cylinder 341 is fixed with the lower surface of the cylinder cover 2, the lower end of the fixed cylinder 341 extends into the rotating cylinder 331, and the inner circumferential surface of the fixed cylinder 341 is processed with an internal thread 3411. The upper end of the connecting rod 344 is rotationally connected with the crank 342, the planetary gear 345 is located between the crank 342 and the mounting support 343, and the planetary gear 345 is threadedly connected with the internal thread of the fixed cylinder 341. The lower end of the connecting rod 344 is fixedly connected with the stirring rod 31 after rotatingly penetrating the mounting cylinder 333. In operation, the rotating rod 323 rotates to drive the crank 342 to rotate synchronously. When the crank 342 rotates, the connecting rod 344, the planetary gear 345, the mounting cylinder 333 and the stirring rod 31 are synchronously moved along the circumference of the rotating rod 323 to realize the revolution movement of the stirring rod 31. At the same time, the planetary gear 345 is in meshing transmission with the inner circumferential surface of the fixed cylinder 341, and the connecting rod 344 is rotationally arranged, so that when the planetary gear 345 moves along the circumference, it must rotate with the fixed cylinder 341 at the same time to drive the connecting rod 344 to rotate. The rotation of the connecting rod 344 must drive the fixedly connected stirring rod 31 to rotate to realize the rotation of the stirring rod 31. That is, the stirring rod 31 rotates while revolving to realize sufficient stirring in the leaching process, promote the suspension and uniform dispersion of the ore particles in the leaching liquid, and make the ore particles and the leaching liquid fully mixed to improve the leaching efficiency. The stirring can also accelerate the relative flow of the ore particles and the leaching liquid to improve the leaching speed.

Therefore, when the connecting rod 344 rotates, the limiting ring 346 can ensure the accurate position of the connecting rod 344 to effectively ensure that the stirring rod 31 stirs in an orderly manner.
