Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a lithium salt clinker leaching and separation device. Background Technology

[0002] Lithium salts are salts containing lithium. Lithium is a trace element; there is no free lithium in nature, and it is usually a monovalent cation. In the 1940s, Cade first successfully used lithium salts to treat mania. In fact, antimania drugs are only of the lithium salt class, with lithium carbonate being the most commonly used. Lithium carbonate is usually prepared by lime sintering: spodumene concentrate (generally containing 6% lithium oxide) and limestone are mixed and ground in a weight ratio of 1:(2.5-3), sintered at 1150-1250 degrees Celsius to produce lithium aluminate and calcium silicate, then pulverized into powder. Lithium hydroxide is leached out with a washing solution, filtered after sedimentation, and the leachate is concentrated by evaporation. Sodium carbonate is then added to produce lithium carbonate. Leaching separation equipment is required when leaching lithium hydroxide from the powdered mixture and filtering out impurities.

[0003] The existing Chinese utility model patent with publication number CN116254411A discloses a chemical clinker leaching and separation device, including a fixed base, a receiving support, and a working component. The receiving support is fixedly installed on the upper end of the fixed base, and the working component is fixedly installed on the receiving support. The working component first pours the powdered ingredients into the fixed cylinder through the feeding component. The rotating shaft is driven by a power motor to rotate, thereby agitating the ingredients and water with a V-shaped agitator. Then, an alkaline washing solution is added through the liquid inlet funnel. The V-shaped agitator and the filter residue treatment component ensure that the materials in the fixed cylinder are evenly mixed. After that, the power motor is turned off, allowing the solution in the fixed cylinder to fully react and generate filter residue. After the first filtrate is discharged, the inner wall of the fixed cylinder is rinsed by a spray component, and the filter residue is cleaned by the filter residue treatment component to ensure that there is no filtrate residue on the surface of the filter residue. The cleaning solution is then discharged in the same way as the first filtrate. Finally, the filter residue is discharged from the fixed cylinder through the filter residue treatment component.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that when preparing lithium salt clinker, the mixed powder and washing liquid need to be stirred and precipitated. After precipitation, a certain amount of filter residue will be generated inside the device. The traditional treatment method is to directly pour out the filter residue, resulting in the inability to treat the residual filtrate on the top of the filter residue, which leads to overall resource waste. When the mixed powder and washing liquid are stirred, some of the filter residue will adhere to the inside of the device, making it difficult to clean later. All these problems affect the use of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a lithium salt clinker leaching and separation device, which effectively prevents the traditional processing method from directly pouring out the filter residue, resulting in the inability to process the residual filtrate at the top of the filter residue and causing overall resource waste, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lithium salt clinker leaching and separation device, comprising a preparation structure component, wherein a pushing scraping component for scraping off filter residue from the inner wall of the tank is installed inside the preparation structure component, and a filter residue filtering component for filtering the discharged filter residue is installed at the lower end of the preparation structure component.

[0016] Compared with the prior art, the present invention provides a lithium salt clinker leaching and separation device with the following advantages:

[0017] This invention features a push-scraping assembly with a structural ring that connects to and drives an upper push rod, allowing for length adjustment. A drive ring is mounted on the side of the push rod, and a telescopic rod at the top of the drive ring extends and retracts the upper scraper to remove residue from the inner wall of the storage tank. This structure facilitates the removal of residue from the inner wall of the device and effectively prevents filter residue from adhering to the inside of the device during mixing of powder and washing liquid, thus avoiding subsequent cleaning difficulties.

[0018] This invention relates to a filter cake filtration assembly. The assembly includes a connecting groove for storing the filter cake that leaks down from the top. A placement box is installed at the bottom, containing multiple layers of filter plates. These plates filter the filter cake, removing the filtrate inside. A filtrate box is also installed at the bottom to store the filtered liquid. This structure effectively prevents the direct dumping of the filter cake, which in traditional methods leaves residual filtrate on the top and wastes resources. Attached Figure Description

[0035] In use, firstly, the required powdered material is poured into the storage tank 101 through the material inlet 103, and the liquid material is poured into the storage tank 101 through the liquid inlet pipe 104. Then, the motor 105 at the top of the device is turned on.

After even mixing, the stirring rod 106 is stopped, and the mixed liquid is allowed to stand. After a period of standing, filtrate and residue will be produced. The baffle 110 at the top of the filtrate outlet 109 is opened via the terminal to discharge the filtrate from the storage tank 101. After the filtrate is discharged, the residue is discharged. To facilitate the complete discharge of the residue from the tank, a push scraper component 2 is installed inside. After stirring, the fan blade 107 is controlled via the terminal. The radial retraction is avoided to prevent interference with the scraper 205. Then, the push rod 202 is activated to extend it axially. The push rod 202 drives the drive ring 203 and the scraper 205 installed on the outer end of the drive ring 203 to move downward along the inner wall of the storage tank 101. At the same time, the telescopic rod 204 has radially adjusted the scraper 205 to abut against the inner wall of the storage tank 101.
