Description

Technical Field

[0001] This cyanide smelting tailings acid treatment device belongs to the field of cyanide smelting tailings acid treatment technology, and relates to a cyanide smelting tailings acid treatment device. Background Technology

[0002] Cyanide smelting tailings mainly refer to the tailings containing acidic components and toxic and harmful substances produced during the gold smelting process using the cyanide gold extraction method. The cyanide method is the most important production method in the gold metallurgy field because of its advantages such as simple process, low cost and high recovery rate. However, the cyanide gold extraction process generates a large amount of solid waste, namely cyanide tailings. These tailings not only contain unreacted cyanide, but may also contain acidic components and other toxic and harmful substances.

[0003] For example, CN212419079U discloses an acid treatment device for cyanide tailings from gold smelting, belonging to the field of cyanide tailings treatment technology. It includes a reaction tank, with a support column fixedly installed at the bottom and a vertical rod fixedly installed at the top. A horizontal plate is fixedly installed on the vertical rod, and a horizontal plate is rotatably installed at the bottom of the horizontal plate. A connecting rod is fixedly installed at the bottom of the horizontal plate, and a positioning block is fixedly installed at the bottom of the connecting rod. A swing plate is hinged to the positioning block, and a stirring rod is rotatably installed at the bottom of the swing plate. Stirring blades are installed on the stirring rod. A track groove is provided at the bottom of the horizontal plate, and a movable block is slidably installed in the track groove. This invention breaks down large-particle cyanide tailings, increases the contact area between the cyanide tailings and the reactants, improves the reaction rate and treatment efficiency, achieves large-area stirring within the reaction tank, ensures uniform mixing of the reactants, complete reaction, and good treatment effect.

[0004] When using the above technical solution, although it increases the contact area between the cyanide tailings and the reactants, improves the reaction rate and processing efficiency, and achieves large-area stirring in the reaction tank, resulting in uniform mixing of the reactants, sufficient reaction, and good treatment effect, the above technical solution has the following drawbacks when treating cyanide smelting tailings acid: due to the different densities of the cyanide smelting tailings acid and the reactants, the cyanide smelting tailings acid tends to accumulate at the bottom of the tank during mixing with the reactants, which can easily lead to uneven mixing. Utility Model Content

[0008] The reaction assembly includes a tank, and a frame is fixedly connected to the end of the rotating shaft. The frame is fixedly connected to the tank, and the upper part of the inner cavity of the frame is movably connected to the lower part of the tank through a bearing.

[0009] A fixed gear is fixedly connected to the other side of the support plate, and a gear transmission assembly is meshed with the other side of the fixed gear. The gear transmission assembly is set in the inner cavity of the frame, and a hollow rotating rod is set in the inner cavity of the tank.

A first stirring rod is fixedly connected to the hollow rotating rod surface, and a second stirring rod is fixedly connected to the rotating rod surface.

[0012] A pipe is connected to the upper left side of the tank body, a connecting flange is fixedly connected to the upper part of the pipe, and a valve is fixedly connected to the surface of the pipe.

[0013] A counterweight is fixedly connected to one side of the upper part of the base plate, and a fixed base is fixedly connected to the lower part of the motor. The lower part of the fixed base is fixedly connected to the upper part of the base plate.

[0014] Compared with the prior art, the beneficial effects of this cyanide smelting tail acid treatment device are as follows: Through the combined use of the above-mentioned structures, this utility model has the following beneficial effects: When mixing cyanide smelting tail acid with reactants, this device can flip the cyanide smelting tail acid at the bottom to the upper part of the tank cavity, thereby avoiding the problem of uneven mixing caused by the different densities between the cyanide smelting tail acid and reactants settling at the bottom of the tank.

[0026] The drive assembly includes a motor 3, a first synchronous pulley 4 is fixedly connected to the output shaft of the motor 3, a synchronous belt 5 is sleeved on the surface of the first synchronous pulley 4, a second synchronous pulley 6 is connected to the upper part of the inner cavity of the synchronous belt 5, a rotating shaft 7 is fixedly connected to the inner cavity of the second synchronous pulley 6, and the rotating shaft 7 passes through the support plate 2 and is movably connected to the contact position of the support plate 2 through a bearing.

[0027] The reaction assembly includes a tank 8, and a frame 9 is fixedly connected to the end of a rotating shaft 7. The frame 9 is fixedly connected to the tank 8, and the upper part of the inner cavity of the frame 9 is movably connected to the lower part of the tank 8 through a bearing.

[0028] A fixed gear 10 is fixedly connected to the other side of the support plate 2, and a gear transmission group 11 is meshed with the other side of the fixed gear 10.

[0031] During operation: When acid treatment of cyanide smelting tailings is required, motor 3 is started, driving the first synchronous pulley 4 to rotate.

Since the tank 8 is located inside the frame 9, the frame 9 then drives the tank 8 to rotate. As the tank 8 rotates, it flips the cyanide smelting tailings acid from the bottom of the tank 8 to the top, allowing it to mix thoroughly with the reactants.
