Method of quickly synthesizing ternary lithium battery cathode material precursor with double kettles

The invention belongs to the field of manufacturing battery materials and particularly relates to a method of quickly synthesizing a ternary lithium battery cathode material precursor with double kettles. Materials are fed into a reaction kettle, and when the liquid level in the reaction kettle is raised to an overflow port, the slurry overflows into a thickener. The bottom of the thickener is connected to a circulating pump. An outlet of the circulating pump is led to interior of the reaction kettle so as to pump the slurry in the thickener back to the reaction kettle. In a filter portion in the thickener, filter bars are regularly arranged and are gathered and connected to a vacuum buffer tank; a part of the slurry is filtered through the filter bars so that granules in the slurry is blocked in the thickener; the condensed slurry is pumped back to the reaction kettle through the circulating pump and is continuously subjected to the reaction, while a mother liquid passing through the filter bars is discharged into the vacuum buffer tank. In the method, due to the structure of large kettle and small kettle, crystal seeds are produced in the small kettle and crystal is grown in the large kettle, so that synthesis time is reduced from more than 180 h to lower than 100 h. In addition, due to large feeding quantity to the reaction system, the method has no loss of solid granules and is high in yield; therefore, synthesis efficiency is increased by 275% and yield is increased to 99.0%.

Cup seal and master cylinder using the same

In a cup seal, the hydraulic pressure in a first hydraulic chamber (6) causes a first seal portion (21e) of an outer lip portion (21c) to closely contact to a bottom wall (20a) of a recessed portion (20) and causes a second seal portion (21f) of a base portion (21a) to closely contact to a rear surface (20b) of the recessed portion (20). A double seal due to the first and second seal portions (21e) and (21f) reliably prevents the leakage of a brake fluid from the first hydraulic chamber (6). If the pressure becomes negative in the first hydraulic chamber (6), the tip portion of the outer lip portion (21c) deflects inward and the outer peripheral end of the base portion (21a) deflects forward. Therefore, the brake fluid in the reservoir flows into the first hydraulic chamber (6) through the gaps among the second and first seal portions (21f), (21e) and the wall surface of the recessed portion (20) to maintain fluid-feeding performance.
