Embodiment 1

[0029] A spray drying and granulation device, comprising a drying tower 1, the upper end of the drying tower 1 is respectively connected with an atomizing nozzle 11 and a heating and air supply device 12, the atomizing nozzle 11 is connected with a material liquid pipe 13, and the lower end of the drying tower 1 is connected with a Discharge cone 2; the drying tower 1 is equipped with a driving mechanism 3, the output shaft of the driving mechanism 3 is connected with a rotating shaft 4, and the rotating shaft 4 is connected to the side wall of the drying tower 1 through a bearing, and the other end of the rotating shaft 4 is fixed with The turntable 5, the edge of the turntable 5 is fixed with a support rod 51, the other end of the support rod 51 is connected with a connecting rod 52 through a bearing, the other end of the connecting rod 52 is hinged with a lifting rod 6, and the other end of the lifting rod 6 is fixed with a push plate 7 , The push plate 7 is set in the dryin...

Embodiment 2

[0032] On the basis of Embodiment 1, a feed plate 21 is fixed inside the discharge cone 2, and a number of feed holes 211 are arranged on the feed plate 21. The lower side of the feed holes 211 is covered with a rubber sheet 22. One end of the sheet 22 is fixed on the feed plate 21 .

[0033] When the air flow goes down, the rubber sheet 22 at the feed hole 211 is pushed away, and the particles can fall into the discharge cone 2 from the feed hole 211 . And when the airflow is upward, the rubber sheet 22 will be close to the feed plate 21 under the action of the airflow, and the feed hole 211 will be closed, so as to avoid the situation that the particles in the discharge cone 2 are brought into the drying tower 1 again, and ensure the accurate collection of the particles.

Embodiment 3

[0035] On the basis of embodiment one or embodiment two, described driving mechanism 3 comprises motor 31, and the output shaft of motor 31 is connected with speed reducer 32, and motor 31 and speed reducer 32 are all installed on the drying tower 1, and the speed reducer 32 Output shaft and rotating shaft 4 are fixed.

[0036] After the motor 31 is started, the motor 31 drives the reducer 32 to act, and the reducer 32 can drive the rotating shaft 4 to rotate, so that the turntable 5 rotates accordingly. Driven by the drive mechanism 3, the push plate 7 can move back and forth continuously, and the atomized material in the drying tower 1 can be fully and uniformly mixed with the heating air, ensuring that the atomized material is evenly heated.

Description

technical field [0001] The invention relates to the field of spray granulators, in particular to a spray drying and granulation method and a device thereof. Background technique [0002] Spray granulation is a method of using a spray dryer to evaporate the solvent in the slurry droplets to obtain dry powder by means of atomization and heat. The spray drying process is the process in which the slurry passes through the atomizer to quickly dry the slurry droplets into granules. Spray drying is not only widely used in traditional ceramics, organic and inorganic chemicals, powder metallurgy, food, and pharmaceutical industries, but also in various modern electronic and functional ceramic industries. Spray drying has become an important process measure that is indispensable for the preparation of modern oxide ceramics with uniform composition, uniform density of dry-pressed green bodies, and obtaining originals with consistent performance. [0003] The utility model patent with...
