Description

Technical Field

[0001] The utility model relates to the field of organic fertilizer production, in particular to an organic fertilizer spraying granulation device. Background Art

[0002] Spray granulation is often used in the production of organic fertilizers. Urea is melted into liquid slurry in a melter, and the slurry is sprayed and atomized to form atomized slurry. The remaining raw materials are stirred into powdered raw materials in a mixer. The powdered raw materials are fully in contact with the slurry in the granulation barrel, and saturated steam is introduced at the same time. After drying, screening and cooling processes, compound fertilizer granules are made.

[0003] In the existing organic fertilizer spray granulation device, the organic fertilizer powder to be processed is easily affected by factors such as moisture, and the powder particles are prone to uneven sizes. Powder with too large a particle size accumulates on the screen plate, which is easy to cause blockage and reduce the amount of powder falling, making it difficult to clear it in time, and the screen plate cannot discharge the material evenly, which will affect the granulation effect and reduce the granulation efficiency.

[0010] The beneficial effects of the utility model are as follows: 1. After the worker atomizes the slurry, it is passed into the granulation barrel through the ventilation pipe. The worker pours the powder to be granulated into the drop frame. The output shaft of the motor drives the stirring rod to rotate. The rotation of the stirring rod drives the active pulley to rotate. The rotation of the passive pulley drives the pressing rod and the arc sheet to rotate. The rotation of the arc sheet continuously pours the powder into the pressing plate and squeezes the powder on the pressing plate.

One group of protrusions is located in one group of discharge holes on the pressing plate. The protrusions can push the powder on the discharge holes of the pressing plate out, reducing the risk of the discharge holes of the pressing plate being blocked by powder, allowing the pressing plate to discharge smoothly and improving the granulation efficiency.
