Description

Technical Field

[0001] The utility model relates to the technical field of lithium slag recovery, and discloses a device for recycling lithium slag resources. Background Art

[0002] Lithium slag, also known as lithium carbonate slag, is a by-product generated in the process of producing lithium carbonate by the sulfuric acid method. Lithium slag appears yellow-brown in color, is powdery after drying, has small particles, and has a certain adhesiveness. It is mainly divided into two categories: building materials and chemicals, and also has corresponding applications in industries such as agriculture. The lithium slag powder production line undergoes drying and grinding to reach a certain powder fineness. Lithium slag is the residue discharged during the production of lithium salts from lithium ores (such as lepidolite and spodumene). Directly discharging and stacking lithium slag will pollute the surrounding environment, and at the same time, the acid- and alkali-containing slag water flowing out will also affect the ecological balance of the surrounding area. Therefore, realizing the resource utilization of lithium slag is an urgent problem to be solved currently.

[0003] When treating lithium slag, most of the time, industrial-grade concentrated sulfuric acid is added to a box body to neutralize it, and lithium sulfate solution and leaching residue are obtained through leaching to achieve efficient leaching of lithium and maximize the recovery of resources. However, just by adding concentrated sulfuric acid to neutralize it, in actual operation, due to the different sizes of lithium slag, the reaction time with concentrated sulfuric acid is also different, resulting in low work efficiency and limitations. Content of the Utility Model

[0004] Aiming at the defects in the prior art, the device for recycling lithium slag resources provided by the utility model can crush lithium slag to make the sizes of lithium slag consistent, which is convenient for subsequent neutralization with industrial-grade concentrated sulfuric acid, and at the same time is convenient for the effective mixing of industrial-grade concentrated sulfuric acid and lithium slag, with high work efficiency.

[0005] To solve the above technical problems, the utility model proposes the following technical solutions:

[0006] The device for recycling lithium slag resources includes a box body. At both ends of the top of the box body, a clear water injection port and a lithium slag injection port are provided through. A partition is installed inside the box body. Above the partition, a grinding mechanism is movably arranged. In the middle of the partition, a discharge port is provided through, and a first valve is installed on the discharge port. A stirring mechanism is arranged inside the box body, and the stirring mechanism is located below the discharge port. A concentrated sulfuric acid injection pipe is provided through on the side of the box body, and the discharge port of the concentrated sulfuric acid injection pipe is located below the partition.

[0007] Further, the grinding mechanism includes a first motor and a grinding block. The first motor is slidably arranged on the box body. The grinding block is installed at the output end of the first motor. The bottom of the grinding block is arc-shaped, and the top of the grinding block is arranged in an inverted bowl shape. The partition is integrally arc-shaped.

[0008] Further, an extension block is installed on the side of the first motor, and cylinders are arranged on both sides of the first motor. The base of the cylinder is fixed on the box body, and the telescopic end of the cylinder is connected to the extension block.

[0009] Further, the stirring mechanism includes a second motor, a mounting bracket, a rotating rod and stirring rods. The mounting bracket is fixed inside the box body, the second motor is fixedly connected to the mounting bracket, the rotating rod is installed at the output end of the second motor, and multiple stirring rods are evenly installed on the rotating rod.

[0010] Further, a protective block is installed on the top of the second motor, and the protective block is integrally arranged in a conical shape.

[0011] Further, a discharge port is penetrated and arranged at the bottom end of the side of the box body, and a second valve is installed on the discharge port.

[0012] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] By setting the grinding mechanism, the lithium slag and clear water can be ground together to obtain a lithium slag-containing slurry, thereby realizing the pulverization of the lithium slag. By providing a stirring mechanism inside the box body, the concentrated sulfuric acid and the lithium slag-containing slurry put in can be fully mixed and reacted, so as to facilitate the obtaining of lithium sulfate solution and leaching residue, realizing the recycling of lithium slag and preventing waste of resources.
