Description
Technical Field
The invention belongs to the technical field of dryers, and particularly relates to a novel centrifugal type granular fertilizer dryer.
Background
The existing method for producing fertilizer is basically produced by adopting high tower granulation, so that most of the fertilizer is spherical granular, when the fertilizer is granulated by the high tower, various raw materials are mixed to prepare slurry, the slurry is sprayed from the top of the high tower and then cooled to form spherical granular fertilizer, and in order to facilitate the storage and transportation of the fertilizer, the moisture in the fertilizer granules needs to be removed by a dryer.
Traditional fertilizer desiccator is mostly the drum dryer, turn over the stir-fry repeatedly through the lifting blade, make granular fertilizer fully contact with the hot gas flow, in order to reach dry purpose, however drum dryer direction of rotation and the stir-fry mode of turning over of lifting blade are single, the lifting effect is relatively poor, be difficult to guarantee granular fertilizer evenly distributed in the cylinder, drying effect differs, lead to product quality relatively poor, and spherical granular fertilizer turns over to fry the in-process and falls repeatedly in the cylinder, crackle or broken powdering easily appears, cause spherical granular fertilizer outward appearance poor, the powder is many, the low scheduling problem of yield.
To this end, we propose a new centrifugal granular fertilizer dryer to solve the above problems.

2. According to the invention, by arranging the drying screen plate, the centrifugal force of the spherical granulated fertilizer with more water is larger in the rotating process of the drying screen plate and is positioned at the peripheral edge of the drying screen plate, the centrifugal force of the dried spherical granulated fertilizer is smaller, and the spherical granulated fertilizer drops into the conveying pipe below and is discharged under the action of gravity, so that the spherical granulated fertilizer can be fully and uniformly dried, and the spherical granulated fertilizer can be flatly paved on the surface of the drying screen plate under the action of the centrifugal force due to different drying time and different water content of each spherical granulated fertilizer, has larger contact area with hot air flow, has better drying effect, and avoids the problem that waste materials are crushed into powder.
3. The dust filtering net is arranged, so that dust and impurities in hot air can be filtered, pollution to fertilizers is prevented, the product quality is prevented from being influenced, the dust filtering net can rotate along with the sliding sleeve, the contact probability of the dust and the impurities in the hot air is increased, and the dust removing effect is further improved.
4. According to the invention, the shunt strips are arranged, the drying screen plate drives the shunt strips to rotate, and the shunt strips can push the spherical granulated fertilizer on the drying screen plate to rotate, so that the spherical granulated fertilizer is prevented from sliding and rolling in the circumferential direction, and the screening effect is ensured.
5. According to the invention, the exhaust pipe is arranged, hot air flow is discharged from the exhaust pipe, according to the Bernoulli principle, when equal-height flows, the flow velocity of the air flow in the exhaust pipe is higher and the pressure is lower, the air flow velocity in the exhaust pipe is higher and the pressure is lower, and moisture on the surface of the spherical granular fertilizer in the storage tank can be sucked into the exhaust pipe through the meshes and discharged along with the air flow, so that the effect of primary drying is achieved.
6. According to the invention, the drying screen plate drives the permanent magnets to rotate by arranging the permanent magnets and the annular magnet, the two permanent magnets are alternately close to and far away from the N pole and the S pole of the annular magnet, the annular magnet generates periodically-changed attraction and repulsion force to the permanent magnets under the action of magnetic force to drive the drying screen plate to repeatedly deform and shake, and then the spherical granulated fertilizer on the drying screen plate is driven to repeatedly turn over so as to be fully contacted with hot air, and the drying effect is further improved.
