Description

Technical Field

[0001] The utility model mainly relates to the field of screw polishing, and in particular to a lithium carbonate tailings collecting device. Background Art

[0002] Battery-grade lithium carbonate is an important raw material for preparing positive electrode materials for lithium-ion batteries. It can also be used as an electrolyte additive for lithium-ion batteries. It can improve the safety performance and service life of batteries. It is a key raw material for lithium-ion batteries. However, in the production process of battery-grade lithium carbonate, a certain amount of tailings will be produced, and the tailings contain recyclable valuable elements. In the case of scarce resources, recycling the tailings can not only achieve certain economic benefits, but also reduce the waste of battery-grade lithium carbonate. Traditional recycling devices directly perform wet recycling on the tailings, but the presence of large particles in the tailings will cause the reaction to be incomplete, thus affecting the recycling effect.

[0003] In the invention patent application with application number CN202321502663.4, application publication date 2023.06.13, and name "A lithium carbonate tailings collection device", it includes a crushing box, a first screen plate is fixedly connected to the upper part of the crushing box; a second screen plate is not fixedly connected to the lower part of the crushing box; a shaft rod that runs through the top of the crushing box is rotatably connected to the middle part of the crushing box; a circular disc is fixedly connected to the shaft rod corresponding to the position above the first screen plate; a circular array of fixed rods are estimated to be fixedly connected to the upper and lower surfaces of the circular disc; a fling knife is rotatably connected to the fixed rod; a circular array of cutting knives is fixedly connected to the shaft rod corresponding to the position above the second screen plate; the shaft rod is provided with a A first motor is provided, and the output end of the first motor is fixedly connected to the shaft rod. The device cooperates with the swing knife and the cutting knife. During specific operation, the lithium carbonate tailings are first sent into the crushing box, and then the first motor drives the shaft rod to rotate, and then the shaft rod drives the disc to rotate, and the disc drives the swing knife to rotate. The swing knife continuously strikes the lithium carbonate tailings, and at the same time, the tailings are blown to the side wall of the crushing box while being struck, so as to achieve a double crushing effect and high crushing efficiency. After the lithium carbonate tailings are crushed to a certain size, they fall onto the second sieve plate through the first sieve plate, and the rotating shaft drives the cutting knife to crush the lithium carbonate tailings for a second time, so that the lithium carbonate tailings can fully react during wet recovery, thereby increasing the recovery efficiency.

[0004] However, during the actual use of the collection device, there are sometimes agglomerates of relatively high hardness inside the lithium carbonate tailings. These agglomerates are difficult to completely crush during the crushing process of the lithium carbonate tailings. As a result, they will continue to fall from the first screen plate to the surface of the second screen plate and roll, which is difficult to crush and can easily cause damage to the blades.
