[0030] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] As shown in Figures 1-7, the mixing device of this embodiment includes a tank 1, a baffle 2, a tank cover 3, and a mixing component 4. The tank 1 is made of cast concrete and has a chamber 11 and an opening 12. The opening 12 is located at the top of the tank 1 and communicates with the chamber 11. The lower end of the chamber 11 has a chamfer 13 extending from the inner wall of the chamber 11 towards the bottom wall of the chamber 11. The baffle 2 is disposed inside the chamber 11 and extends vertically. The tank cover 3 is located at the opening 12. At least a portion of the mixing component 4 extends into the chamber 11 through the tank cover 3 to mix the material inside the chamber 11.

[0032] Specifically, the tank 1 is cylindrical in shape, and the chamber 11 extends downward from the top of the tank 1. The chamber 11 contains ores or other raw materials and various chemical substances. At least part of the agitator 4 agitates the materials in the chamber 11 so that the ores and chemical substances are fully mixed.

[0033] The mixing device of this utility model has a tank 1 made of concrete, which improves the structural strength and heat insulation effect of the tank 1, saves manufacturing costs, and simplifies the manufacturing process. The chamfer 13 at the lower end of the chamber 11 can prevent materials from accumulating in the dead corner at the bottom of the chamber 11, ensure the mixing effect of the materials, and also simplify the difficulty of laying the anti-corrosion layer in the chamber 11.

[0034] In some embodiments, the baffle 2 is made of acid-resistant bricks. By setting the baffle 2, the flow state of materials and chemical raw materials in the mixing process in the chamber 11 can be optimized, the mixing effect can be improved, the stroke of the eddy can be reduced, and the mixing efficiency can be improved.

[0035] In some other embodiments, the baffle 2 can be cast together with the tank 1 to ensure the structural strength of the mixing equipment.

[0036] Specifically, multiple baffles 2 can be provided, and the multiple baffles 2 are arranged at intervals along the circumference of the chamber 11.

[0037] Specifically, the mixing component 4 includes a mixing bridge 41 and a mixing section 42. The mixing section 42 is mounted on the mixing bridge 41. During installation, the mixing bridge 41 is installed above the tank 1 via pre-embedded bolts on the top surface of the tank 1. The lower end of the mixing section 42 extends into the chamber 11 through the tank cover 3. The concrete structure of the tank 1 provides solid support for the mixing component 4, ensuring stable operation. The mixing section 42 includes a motor 421, a mixing shaft 422, and blades 423. The motor 421 is connected to the upper end of the mixing shaft 422 to drive the mixing shaft 422 to rotate. The lower end of the mixing shaft 422 extends into the chamber 11. The blades 423 are mounted on the mixing shaft 422 to mix the materials in the chamber 11.

[0038] In some embodiments, the chamfer 13 has an inclination angle of 30° to 60°.

[0039] Specifically, when constructing the tank 1 by pouring concrete, a chamfer 13 is made along the circumference of the bottom edge inside the chamber 11 to increase the angle of the inner corner. This not only facilitates the lining construction but also effectively reduces the accumulation of solid materials in the chamber 11 during the mixing process of the mixing component 4. Preferably, the inclination angle of the chamfer 13 is 45°.

[0040] In some embodiments, the inner wall of the chamber 11 is provided with a first anti-corrosion layer 5, which avoids direct contact between the material and the tank 1, prevents the corrosion of the tank 1 by chemicals and the wear of the tank 1 by the ore, ensures the structural strength of the tank 1, and reduces the risk of leakage.

[0041] Specifically, the baffle 2 is also provided with a first anti-corrosion layer 5 to prevent chemical substances from corroding the baffle 2 and to ensure the service life of the baffle 2.

[0042] In some embodiments, the first anti-corrosion layer 5 includes a fiberglass anti-corrosion layer 51, an acid-resistant brick anti-corrosion layer 52, and a putty 53. The fiberglass anti-corrosion layer 51 is laid on the inner wall of the chamber 11, the acid-resistant brick anti-corrosion layer 52 is laid on the fiberglass anti-corrosion layer 51, and the putty 53 is disposed between the fiberglass anti-corrosion layer 51 and the acid-resistant brick anti-corrosion layer 52.

[0043] Specifically, after the tank 1 is poured, a fiberglass anti-corrosion layer 51 is laid on the inner wall of the chamber 11 and the top surface of the tank 1. An acid-resistant brick anti-corrosion layer 52 is laid on the fiberglass anti-corrosion layer 51 with mortar 53, which improves the corrosion resistance and wear resistance of the tank 1 and can effectively cope with the complex working conditions of highly corrosive and high-concentration media in hydrometallurgical processes. In addition, the main material of the tank 1 is concrete, and the anti-corrosion lining of the chamber 11 uses acid-resistant brick material, which can effectively slow down the heat transfer rate and improve the insulation effect.

[0044] Specifically, the acid-resistant brick anti-corrosion layer 52 is composed of multiple acid-resistant bricks stacked together, and adjacent acid-resistant bricks are fixedly connected by mortar 53 to ensure the structural strength and stability of the acid-resistant brick anti-corrosion layer 52.

[0045] In some embodiments, the mixing device further includes a feed pipe 6, which is pre-embedded in the tank 1 and communicates with the chamber 11 to facilitate filling or discharging materials into the chamber 11.

[0046] In some embodiments, the feed pipe 6 includes a positioning plate 61, a pipe body 62, and a flange 63. The positioning plate 61 is disposed on the outer wall of the pipe body 62 and embedded in the peripheral wall of the tank 1. One end of the pipe body 62 passes through the first anti-corrosion layer 5 and communicates with the chamber 11, and the other end of the pipe body 62 passes through the peripheral wall of the tank 1 and communicates with the outside. The flange 63 is disposed at the other end of the pipe body 62.

[0047] Specifically, before pouring the tank 1, the positioning plate 61, the pipe body 62 and the flange 63 are welded together according to the dimensions. When pouring the tank 1, the pipe body 62 is pre-embedded in the tank 1 through the positioning plate 61 to position the pipe body 62, reducing the difficulty of positioning construction. Moreover, the structure of the material pipe 6 is simple and easy to manufacture.

[0048] In some embodiments, the inner wall surface of the pipe body 62 and the outer end face of the flange 63 are provided with a fiberglass anti-corrosion layer 51 to ensure that the pipe body 62 is not easily corroded when the material passes through it, thereby improving the service life of the material pipe 6.

[0049] In some embodiments, the slot cover 3 includes a first part 31, a second part 32, a third part 33, a first connector 34, and a second connector 35. The first connector 34 is disposed between the first part 31 and the second part 32 to connect the first part 31 and the second part 32. The second connector 35 is disposed between the second part 32 and the third part 33 to connect the second part 32 and the third part 33. The first part 31, the second part 32, and the third part 33 are spliced ​​together by the first connector 34 and the second connector 35, and the outer periphery of the slot cover 3 is circular. Preferably, bolts are pre-embedded on the top surface of the slot body 1, and the slot cover 3 is installed on the slot body 1 by the pre-embedded bolts. In other embodiments, the slot cover 3 and the slot body 1 can also be directly connected by bolts or other connectors.

[0050] In some embodiments, the tank cover 3 further includes gaskets 36 and a second anti-corrosion layer 37. Gaskets 36 are provided between the first part 31 and the second part 32, and between the second part 32 and the third part 33, to ensure the sealing of the tank cover 3. The second anti-corrosion layer 37 is laid on the bottom surface of the first part 31, the second part 32, and the third part 33 to ensure that the tank cover 3 is not easily corroded. Specifically, the second anti-corrosion layer 37 is a fiberglass anti-corrosion layer 51.

[0051] In other embodiments, the second anti-corrosion layer 37 covers the first part 31, the second part 32 and the third part 33, making the tank cover 3 less susceptible to corrosion and ensuring the service life of the tank cover 3.

[0052] In some embodiments, a pad 7 is provided between the tank cover 3 and the tank body 1. Specifically, the pad 7 is annular and is laid on the top surface of the tank body 1 and located between the tank body 1 and the second anti-corrosion layer 37 provided on the ground of the tank cover 3, thereby optimizing the contact surface between the tank cover 3 and the tank body 1.
