The rotating nozzle is connected to the potassium molten tank through a feed pipe; an air guide component is provided on the outer sleeve of the reaction vessel. By this means, the rotating nozzle in this scheme sprays liquid potassium all around. This design makes the distribution range of liquid potassium wider. The introduction of the air guide component divides the compressed air into two parts, one part of which is oxygen supply for the liquid potassium reaction; the other part can take away the temperature on the potassium superoxide powder to accelerate the cooling speed of the potassium superoxide powder, and can also break up the potassium superoxide powder to avoid the agglomeration of the potassium superoxide powder.

6. A method for preparing potassium superoxide based on a potassium superoxide preparation device as claimed in claim 5, characterized in that: include: S1, the heater (3) heats the potassium powder in the potassium melting tank (2) to melt and maintain the temperature at 90-120°C, and at the same time, multiple jet pipes (8) spray high-temperature air into the middle of the atomizing chamber of the atomizing tank (1), and the temperature of the high-temperature air is 100-150°C; S2, the driving assembly (7) drives the shaft tube (5) to rotate, so that the liquefied potassium passes through the aligned micropores 1 of the bottom plate (4) and the micropores 2 of the droplet plate (6) to form liquid potassium droplets. The liquid potassium droplets are impacted by the high-temperature air and collide with each other, so that the liquid potassium droplets are broken again. At the same time, the liquid potassium droplets react with oxygen in the air to prepare potassium superoxide powder. The potassium superoxide powder falls into the lower part of the atomization chamber of the atomization tank (1) and spirals down with the high-temperature air. Under the action of centrifugal force, the potassium superoxide powder gathers at the bottom material outlet of the atomization tank (1) and is discharged into the feeding pipe (16). At the same time, the potassium superoxide powder compresses and gathers the exhaust gas to the lower end of the shaft tube (5), so that the exhaust gas is discharged into the dust removal tank (10) through the shaft tube (5); S3, the exhaust gas outputted from the shaft tube (5) is inputted into the bottom of the filter chamber of the dust removal tank (10), and the exhaust gas is filtered by the filter bag (11) and then discharged through the air outlet of the dust removal tank (10), thereby achieving exhaust gas filtration treatment; S4, the motor (17) drives the spiral blade (19) to rotate through the feed shaft tube (18), and the spiral blade (19) conveys the potassium superoxide powder to the discharge port of the feed tube (16). During the conveying process of the potassium superoxide powder, the feed shaft tube (18) drives the paddle plate (23) to rotate, and the paddle plate (23) scoops up the potassium superoxide. The potassium superoxide powder with a particle size that meets the standard falls through the sieve holes, and the potassium superoxide powder with a particle size that is too large enters the multiple openings of the feed shaft tube (18) along the paddle plate (23). Since the feed shaft tube (18) and the fixed shaft (20) rotate relative to each other, the grinding assembly (22) grinds the potassium superoxide powder that enters between the fixed shaft (20) and the feed shaft tube (18), and the ground potassium superoxide powder is discharged when it reaches the next downward opening, so that the potassium superoxide powder is conveyed and ground at the same time.
