Description

Technical Field

[0001] The utility model belongs to the technical field of lithium carbonate production equipment, and specifically relates to a stirring device for producing lithium carbonate intermediate products. Background Art

[0002] The stirring equipment for lithium carbonate intermediates is a mechanical device specially designed to evenly mix and stir the intermediates during the production of lithium carbonate. Through its unique stirring system and structure, the equipment ensures that the lithium carbonate intermediates are fully mixed and stirred under specific process conditions, thereby meeting the quality and efficiency requirements of the production process.

[0003] The lithium carbonate intermediate product is sticky. During the stirring production process, it is easy to adhere to the inner wall of the stirring tank, resulting in uneven stirring and mixing. In subsequent use, more adhesion will cause waste. Moreover, after the stirring production is completed, when the inner wall of the stirring tank is cleaned, it is easy to not clean it cleanly enough, which in turn affects the subsequent production quality. For this reason, we propose a stirring equipment for producing lithium carbonate intermediate products. Utility Model Content

[0008] Preferably, a lifting cylinder is provided on the upper surface of the mixing tank, and two lifting cylinders are provided, and the upper ends of the two lifting cylinders are respectively fixedly connected to the lower surfaces of the upper ends of the two L-shaped lifting plates.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The stirring device for producing lithium carbonate intermediate products can, through the scraping mechanism, enable the lifting cylinder to drive the L-shaped lifting plate and the ball to press down during the stirring process, so that the annular downward pressing plate pushes the scraper toward the inner wall of the stirring tank through the wedge block, so that the scraper can scrape the inner wall of the stirring tank during the rotation process, thereby preventing the lithium carbonate intermediate product from adhering to the stirring tank during stirring and mixing, thereby improving the stirring and mixing quality.

[0019] It should be noted that the left and right groups of fixed sleeve rods 701 and scrapers 703 are respectively located in the middle of the stirring rods 6 at the front and rear ends of the left side and in the middle of the stirring rods 6 at the front and rear ends of the right side. The scrapers 703 will not contact the stirring rods 6 when rotating. When the scrapers 703 are not in contact with the inner wall of the stirring tank 1, they achieve the same function as the stirring rods 6, stirring and mixing the lithium carbonate intermediate product, which can improve the mixing efficiency and mixing quality.

[0020] A wedge block 704 is provided inside the upper end of the scraper 703 near one end of the fixed sleeve rod 701, and the upper end of the wedge block 704 abuts against an annular lower pressure plate 705. The setting of the wedge block 704 can push the scraper 703 toward the inner wall of the mixing tank 1 through the wedge block 704 when the annular lower pressure plate 705 moves downward, so that the scraper 703 contacts the inner wall of the mixing tank 1, and the annular lower pressure plate 705 is provided with two, and the circumferential surface of the rotating shaft 5 is provided with a fixed plate 8, and the fixed plate 8 is provided with two and is respectively located at the upper end and the lower end of the rotating shaft 5. The inner walls of the two annular lower pressure plates 705 are provided with limit blocks 9, and the two groups of limit blocks 9 are respectively slidably installed in the two annular lower pressure plates 705. The setting of the limit blocks 9 makes the annular lower pressure plates The plate 705 can be installed on the circumferential side wall of the fixed plate 8 without affecting the vertical movement of the annular lower pressure plate 705. At the same time, when the rotating shaft 5 drives the fixed plate 8 to rotate, the annular lower pressure plate 705 can be smoothly driven to rotate through the fixed plate 8. The two annular lower pressure plates 705 are fixedly connected by a connecting rod 11. The upper surface of the upper annular lower pressure plate 705 abuts against a ball 706.

[0022] The working principle and use process of the utility model are as follows: when producing lithium carbonate intermediate products, the raw materials are fed into the interior of the stirring tank 1 through the feed port 2, and then the motor 4 is turned on, the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring rod 6, the fixed sleeve rod 701 and the scraper 703 to rotate, so as to stir and mix the lithium carbonate intermediate products. After stirring and mixing for a period of time, the lifting cylinder 10 is started, and the lifting cylinder 10 drives the L-shaped lifting plate 707 and the ball 706 to move downward, thereby pressing the annular lower pressure plate 705 downward, so that the annular lower pressure plate 705 pushes the wedge block 704 toward the inner wall of the stirring tank 1, and the wedge block 704 drives the scraper 703 to approach the inner wall of the stirring tank 1 and contact the inner wall of the stirring tank 1. At this time, the rotating shaft 5 continues to rotate, and the stirring rod 6 still stirs and mixes the lithium carbonate intermediate products. The scraper 703 scrapes the inner wall of the stirring tank 1 to scrape off the material attached to the inner wall of the stirring tank 1 to improve the mixing quality. After the stirring is completed, the valve is opened and the material is discharged through the discharge port 3 for subsequent use.
