Description

Technical Field

[0001] The utility model relates to the field of acid washing and separation of stone materials for metallurgical production, in particular to an acid washing and separation device for stone materials for metallurgical production. Background Art

[0002] The initial raw materials for metallurgy are almost all stones mined from wild mines. This is because most metals in nature do not exist as a single substance or a certain type of compound, but are contained in mines, rare earths and other raw materials together with other substances. Metallurgical production requires separating these metal substances from the mined raw materials, and pickling is one of the separation methods.

[0003] Pickling is a process in which most metals will dissolve in acidic substances in the form of ions, thereby separating them from other substances in the raw materials that are insoluble in the corresponding acidic liquid. The separated liquid is then processed to extract the required metal element or compound. The usual pickling method is to place the stone in a pickling environment, stir the stone and the pickling liquid by stirring, and accelerate the process of metal dissolving in the acid through the contact between the stone and the pickling liquid. However, most stirring methods are to keep rotating on a horizontal plane, which does not have much effect on the exchange of the upper and lower layers of the pickling liquid. The stone itself is heavy and mostly located in the lower layer. When the pickling liquid in the lower layer is relatively saturated with metal ions, the efficiency of pickling separation is reduced, and the pickling liquid with relatively less solute metal in the upper layer is difficult to enter the lower layer in large quantities, or exchange positions with the pickling liquid in the lower layer. Therefore, a stone pickling separation device for metallurgical production is needed. Utility Model Content

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] Combined with Figure 1-4 In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a stone pickling and separation device for metallurgical production, comprising a pickling tank 1, a top side of the pickling tank 1 is connected with a liquid infusion pipe 19, a bottom side of the pickling tank 1 is connected with a liquid discharge pipe 20, a water pump 21 is connected to the liquid infusion pipe 19 and the liquid discharge pipe 20, a discharge port 18 is connected to the bottom of the pickling tank 1, a solenoid valve 22 is connected to the pickling tank 1 at the discharge port 18, a plurality of stirring mechanisms are rotatably connected in the pickling tank 1, and the stirring mechanism comprises a stirring end 17 with a plurality of blades, The stirring end 17 is used to stir and roll the liquid in the pickling tank 1 to facilitate enhanced contact with the stone. The pickling tank 1 is located on both sides of the bracket 9 and is rotatably connected with a support shaft 13 and a driven shaft 15. The stirring end 17 is respectively located on the support shaft 13 and the driven shaft 15 and extends into the pickling tank 1. A second motor 14 that cooperates with the support shaft 13 is downwardly connected to one side above the pickling tank 1 to provide power for the rotation of the support shaft 13. A belt transmission mechanism 16 is commonly connected between the top of the support shaft 13 and the driven shaft 15, so that the support shaft 13 and the driven shaft 15 rotate synchronously.

[0024] The pickling liquid is respectively inputted into and discharged from the pickling tank 1 through the infusion pipe 19 and the discharge pipe 20, and the pickling tank 1 is the place where the metallurgical stone is pickled and separated. The metal part dissolved in the corresponding acid solution in the stone is dissolved by the acid liquid, thereby separating. The stirring end 17 is used to stir the pickling liquid to expand the contact with the stone.

[0025] Embodiment 2

[0026] Combined with Figure 1-5 A bracket 9 is connected to the top of the pickling tank 1, and a support column 3 is rotatably connected to the bottom of the bracket 9. The bottom end of the support column 3 extends into the pickling tank 1 and is connected to a net box 2. The top of the net box 2 is connected to a feed port 10. A discharge portion 11 is connected to the bottom of the net box 2. A spiral feeder 12 is connected to the discharge portion 11 to facilitate the discharge of stones. The stirring mechanism is arranged on both sides of the net box 2. A lifting mechanism that cooperates with the net box 2 is connected to the top of the bracket 9. The lifting mechanism includes a conduction column 5. A slide groove 6 is connected to the outside of the conduction column 5. The slide groove 6 is on the outer wall of the conduction column 5 at two ends. The sides are V-shaped and the V-shaped tops on both sides are connected to each other. The top of the support column 3 is connected to a sliding frame 4 that cooperates with the slide groove 6. The two connected V-grooves on the conduction column 5 can also be understood as an M-shaped groove or W-shaped groove that is connected in the first place. Through the limiting path of the slide groove 6, when the conduction column 5 rotates, the support column 3 is repeatedly moved up and down in the bracket 9 and the pickling tank 1 through the transmission of the sliding frame 4. The top of the bracket 9 is rotatably connected to a transmission shaft 7 that cooperates with the conduction column 5, which drives the conduction column 5 to rotate. The top of the bracket 9 is connected to a No. 1 motor 8 that cooperates with the transmission shaft 7 to provide power for the rotation of the transmission shaft 7.

[0027] The transmission shaft 7 drives the conduction column 5 to rotate. Under the action of the slide groove 6, the sliding frame 4 below drives the support column 3 to move up and down reciprocatingly, so that the mesh box 2 in the pickling tank 1 also moves up and down. The mesh box 2 provides a place for placing stones, which separates the stones from the environment of the pickling tank 1, and cooperates with the spiral feeder 12 to facilitate the discharge of the remaining stones after pickling. Under the action of the lifting mechanism, the mesh box 2 facilitates the further and better contact of the stones carried inside with the pickling liquid. It is worth noting that the components in the device that come into contact with the pickling liquid are all made of acid-resistant materials. Since this is common sense in this field and the specific material selection is also within the existing technology, it is only used as a reminder here without further elaboration.

[0028] During the specific implementation of the utility model, when the device is used to perform metal separation treatment on metallurgical ore by pickling, the stone as raw material is placed in the mesh box 2, and then the corresponding pickling liquid is introduced into the pickling tank 1, and the device can be started to perform pickling separation operation. The stirring end 17 rotates on both sides of the mesh box 2 under the power support provided by the operation of the second motor 14 to stir the pickling liquid, and the liquid is circulated and continuously flows to the stone in the mesh box 2 through the centrifugal action. At the same time, the lifting mechanism drives the mesh box 2 to circulate in the pickling tank 1 through the power support provided by the operation of the first motor 8. The reciprocating up and down movement cooperates with the stirring mechanism to further enhance the contact between the pickling liquid and the stone in the mesh box 2, which makes the pickling more thorough and rapid. When the pickling is completed, first, the pickling liquid containing metal ions in the tank is discharged by opening the lower water pump 21, and discharged into the corresponding collection mechanism to wait for subsequent processing. After the liquid is discharged, under the action of the lifting mechanism, the mesh box 2 carries the pickled stone to the bottom of the pickling tank 1. At this time, the discharge part 11 of the mesh box 2 is just above the discharge port 18 of the pickling tank 1. The stone can be discharged by opening the solenoid valve 22 and running the screw feeder 12.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
