The filtering apparatus 2 comprises a filtering cylinder 12, a depositing cylinder 14 and a recycling groove 20, the bottom of the filtering cylinder 12 is connected with a connecting pipe 10, the sedimentation cylinder 14 is arranged in the filter cylinder 12, the bottom of the sedimentation cylinder 14 is connected with an injection pipe 9, the other end of the injection pipe 9 is inserted at the position close to the right end of the top of the cylinder 3, a first metering pump 11 is arranged on the injection pipe 9, the recovery tank 20 is arranged in the filter cylinder 12 near the top, the recovery tank 20 is a circular ring-shaped structure, an inclined plate 15 is arranged at the hollow position of the recovery tank 20, a pore plate 19 is arranged above the inclined plate 15, a high-density filter cloth 18 is arranged above the orifice plate 19, the recovery tank 20 is connected with a delivery pipe 17, the other end of conveyer pipe 17 is connected with storage jar 21, be provided with second measuring pump 16 on the conveyer pipe 17.

The delivery pipe 17 is provided with a pressure transmitter 13 at a position close to one end of the recovery tank 20.

The other end of the connecting pipe 10 is connected with the cylinder 3, and the end of the connecting pipe 10 connected with the cylinder 3 is provided with a certain inclination angle a, and the inclination angle a is 20 degrees inclined relative to the horizontal plane.

As shown in fig. 2, two ends of the orifice plate 19 are provided with a clamping groove 22, the clamping groove 22 is provided with a rubber block 23 corresponding to the clamping groove 22, and the outer edge of the high-density filter cloth 18 is pressed into the clamping groove 22 through the rubber block 23 for fixing.

As shown in fig. 3, perforated plates 19 are provided above and below the high-density filter cloth 18, and are pressed and fixed by the perforated plates 19.

In the using process, the ternary precursor is injected into the barrel 3 through the injection port 4, and then the rotating shaft 7 is driven to rotate through the motor 5, so that the stirring blade 8 is driven to stir; because the cylinder 3 is connected with the filter cylinder 12 through the connecting pipe 10, the ternary precursor in the cylinder 3 flows into the filter cylinder 12 along the connecting pipe 10, and the liquid level in the cylinder 3 is always the same as that in the filter cylinder 12 due to the principle of the U-shaped pipe; the height of the high-density filter cloth 18 is slightly lower than the liquid level in the filter cylinder 12, when the ternary precursor flows into the filter cylinder 12 and gradually reaches the same height as the liquid level in the cylinder 3 through the upwelling on the two sides of the deposition cylinder 14, the moisture of the ternary precursor at the liquid level is filtered through the high-density filter cloth 18, the filtered moisture overflows into the recovery tank 20, while the concentration of the filtered ternary precursor is relatively concentrated with respect to the concentration of the ternary precursor just injected into the filter cartridge 12, therefore, the filtered ternary precursor gradually sinks into the deposition cylinder 14, and then the ternary precursor deposited in the deposition cylinder 14 is infused back into the cylinder 3 through the injection pipe 9 for secondary stirring, so that the particles in the purified ternary precursor are secondarily wrapped, thereby improving the diameter of the particles and then outputting the purified ternary precursor in the cylinder 3 through the output port 6.

The water yield in the accumulator 20 can produce certain pressure to the mouth of pipe of conveyer pipe 17 after accumulating gradually, can push away pressure transmitter 13 after pressure reaches certain pressure value, then carry the water of straining off to storage jar 21 in, after the water of straining off has carried gradually, the mouth of pipe position department pressure of conveyer pipe 17 reduces, after the certain pressure value that pressure reduces, pressure transmitter 13 can be closed thereupon to stop carrying the water of straining, so go round and begin.

The first metering pump 11 is arranged to facilitate the injection pipe 9 to pump out the ternary precursor in the deposition cylinder 14 and inject the ternary precursor into the cylinder 3, and the second metering pump 16 is arranged to facilitate the filtered water to be pumped out and conveyed into the storage tank 21.

The arrangement of the inclination angle a can facilitate the backflow of the ternary precursor, thereby preventing the ternary precursor from blocking the orifice of the connecting pipe 10 when flowing to the filter cartridge 12.

The outer edge of the high-density filter cloth 18 is pressed into the clamping groove 22 through the rubber block 23, so that the high-density filter cloth 18 can be conveniently fixed, the high-density filter cloth 18 is prevented from being flushed away from the position of the high-density filter cloth 18 by upwelling ternary precursors, or the high-density filter cloth 18 is clamped and fixed at the position of the high-density filter cloth 18 by arranging the pore plates 19 above and below the high-density filter cloth 18.

The arrangement of the pore plate 19 and the inclined plate 15 can buffer the impact force of the ternary precursor which flows upwards, so that the ternary precursor which flows upwards to the position of the liquid level can be conveniently filtered by the high-density filter cloth 18.

The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
