Lithium iron phosphate battery, which is a lithium ion battery using lithium iron phosphate (LiFePO 4) as a positive electrode material and carbon as a negative electrode material, has low electron conductivity and low lithium ion diffusion rate, resulting in initial capacity loss and poor rate discharge performance; the bulk density is low, so that the volume energy density is low, the problem of low electron conductivity of lithium iron phosphate (LiFePO 4) can be improved by adding a conductive agent, and the problem of low bulk density can be realized by changing the shape of the lithium iron phosphate. Research shows that spherical or sphere-like lithium iron phosphate can greatly improve tap density and capacitance, therefore, the lithium iron phosphate battery material needs to be granulated in production, the adopted equipment is generally a spray fluidization granulating and drying tower, when in use, liquid materials are atomized through an airflow atomizer (also called a nozzle), sprayed onto the surfaces of solid particles (called seed crystals) in a fluidized state in a drying chamber, quickly dried by hot air, quickly evaporated by solvent and the dry matters remained on the surfaces of the seed crystal particles.

Working principle: when the device works, firstly, when the nozzle 13 sprays liquid materials, the electromagnet 601 is electrified to attract the iron block 602 to enable the third sealing plate 402 to slide into the third fixed cover 401, meanwhile, the second spring 504 is contracted, the U-shaped plate 201 is driven to synchronously move by the connecting plate 603 when the third sealing plate 402 moves, the second sealing plate 20 moves into the second fixed cover 19 when the U-shaped plate 201 moves, and the first sealing plate 17 moves into the first fixed cover 15, so that the first fixed pipe 18 and the through hole 16 are blocked and sealed, on one hand, hot air is stopped from being introduced into the tower 12, on the other hand, air in the tower 12 is prevented from being discharged, and meanwhile, the baffle 202 is driven to move into the tower 12 when the U-shaped plate 201 moves, so that a separation effect is achieved on the inside of the tower 12;
meanwhile, when the U-shaped plate 201 moves, the mounting plate 312 is driven to move through the L-shaped plate 301, so that the limiting surface 307 is propped against the raised strips 310, the rotating disc 309 and the transmission shaft 308 are pushed to rotate, the driving bevel gear 311 and the driven bevel gear 313 are driven to rotate by the rotation of the transmission shaft 308, the rotating rod 205 and the rotating fan 203 are driven to rotate, so that the air flow upwards flows along the baffle 202, and flows to the other side after reaching the top of the tower body 12, finally flows to one side close to the first fixed pipe 18 again through the bottom of the baffle 202, so that the air in the tower body 12 circulates, the dried particles can synchronously circulate along with the circulation of the air, so that the dried particles can be coated with the liquid material sprayed out of the nozzle 13 as much as possible, the repeated coating and drying can be carried out on the dried particles, and after the particles reach a certain granularity, the particles can fall into the bottom of the tower body 12 under the action of gravity to be collected, and the granulating efficiency and the effect of the lithium iron phosphate battery material are ensured;
after the injection of the nozzle 13 is completed, the electromagnet 601 is powered off, at this moment, the third sealing plate 402 moves away from the third fixed cover 401 under the action of the second spring 504, and then drives the U-shaped plate 201, the second sealing plate 20, the baffle 202 and the first sealing plate 17 to move and reset through the connecting plate 603, at this moment, hot air is blown into the tower body 12 through the blower 22 to dry particles, meanwhile, when the hot air enters the first fixed pipe 18, the rotating fan 203 rotates to drive the rotating rod 205 and the stirring plate 1001 to rotate, the stirring plate 1001 scrapes particles at the bottom of the tower body 12 when the stirring plate 1001 rotates, so that the particles can enter the through groove 404 for temporary storage through the discharging pipe 24, when the injection of the nozzle 13 is required, the rotating rod 205 also drives the stirring plate 1001 to synchronously rotate, and at the same time, the third sealing plate 402 moves into the third fixed cover 401, and when the through groove 404 is overlapped with the collecting pipe 403, the particles in the through groove 404 can be discharged through the collecting pipe 403, so that automatic discharging of the particles can be ensured under the condition of no stop, and granulating efficiency is ensured;
and when the third sealing plate 402 moves to the third fixed cover 401 to discharge, the first connecting pipe 701 is driven to move synchronously, and then the first connecting pipe 701 and the third connecting pipe 704 are driven to move synchronously, so that the protruding block 803 slides on the side wall of the protruding block 805, and under the action of the second reset mechanism, the piston 706 can reciprocate in the fourth connecting pipe 705, when the piston 706 moves towards the direction close to the second connecting pipe 703, the gas in the second connecting pipe 703 is extruded, meanwhile, the first one-way valve is closed, the second one-way valve is opened, at this time, the gas in the second connecting pipe 703 is extruded and then reenters the tower body 12 through the hose 707, when the piston 706 moves towards the direction far away from the second connecting pipe 703, negative pressure is generated in the second connecting pipe 703, meanwhile, the first one-way valve is opened, so that the gas in the through groove 404 can enter the second connecting pipe 703 through the first connecting pipe 701, the gas in the through groove 404 can be absorbed and then reentered into the tower body 12, and when the collecting pipe 403 is discharged, the gas is more environment-friendly is avoided.
