s4; drying and granulating: carrying out pressurized spray drying granulation on the uniformly dispersed liquid intermediate prepared in the step S3 to obtain spherical powder of 20-25 mu m, and packaging the prepared spherical powder; the mixed raw materials are dried in a pressurized spray drying mode, the component loss of the mixed raw materials can be effectively reduced, and meanwhile, the influence on the full use effect of the raw materials due to the fact that the attapulgite and the far infrared ceramic powder are serious in a moisture drying pot is prevented.

The specific work flow of the decomposition device is as follows:

when the attapulgite cleaning machine works, when attapulgite is purified, the high-pressure air pump 14 is controlled to fill high-pressure air into the filter plate 13, the high-pressure air entering the filter plate 13 can extrude, contract and close the elastic hose 16, attapulgite ore mixture containing impurities such as soil is crushed and then is input above the filter plate 13, sludge water is added to soak for 18-36 hours, shrimp and crab shell powder is added simultaneously, the high-pressure air sprayed into the air guide cavity 132 is sprayed into the mixture through the air guide rubber ring 3, the soaked mixture is then flushed and stirred by the high-pressure air, after the soaking time is over, the high-pressure air pump 14 supplies air slowly, the restoring force of the elastic hose 16 can open the pipe orifice of the elastic hose 16, the mixture flushed and stirred by the high-pressure air of the filter plate 13 falls onto the slope settling plate 17, and the high-pressure air pump 14 fills the high-pressure air into the air spray cavity 171, the gas entering the air spraying cavity 171 carries out the flushing and turning stirring operation again on the mixture on the slope settling plate 17 through the gas guide micropores, when the mixture is settled for 8 hours after the flushing and turning is finished, the attapulgite ore is at the uppermost layer in the whole sediment due to the lighter specific gravity of the attapulgite ore, a slurry pump is used for sucking the attapulgite ore by a mud suction pipe 18 and sending the attapulgite ore into the settling bin 112 for standing, and the water in the standing upper layer sediment is discharged by a liquid discharge pipe, thereby purifying and preparing the attapulgite; through the cooperation of filter 13 and slope precipitate board 17, filter 13 can filter the earth of large granule or mineral matter impurity, and slope precipitate board 17 can carry out the layering preparation extraction with the attapulgite.
