Novel centrifugal granulated fertilizer dryer

Abstract

The invention belongs to the technical field of dryers, and particularly relates to a novel centrifugal granulated fertilizer dryer. The novel centrifugal granulated fertilizer dryer comprises a shell, wherein the lower end of the shell fixedly communicates with an air inlet pipe, the other end of the air inlet pipe fixedly communicates with an air heater, the upper end of the shell is open, the inner side wall of the upper end of the shell is rotationally connected with a drying net plate, the drying net plate is arranged in a downwards-concave conical face shape, the center of the bottom face of the drying net plate fixedly communicates with a conveying pipe, the lower end of the conveying pipe penetrates through the bottom face of the shell and extends out of the shell, the conveying pipe is in sleeve joint with a sliding sleeve in a rotating mode, and the upper end of the sliding sleeve is fixedly connected with the drying net plate. The novel centrifugal granulated fertilizer dryer can be flatly laid on the surface of the drying net plate according to different water contents and different centrifugal forces of spherical granulated fertilizers, the contact area between the spherical granulated fertilizers and hot air flow is large, the drying effect is good, the dried fertilizers can automatically fall off and be discharged from the conveying pipe, and sufficient and uniform drying is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of dryers, in particular to a novel centrifugal granular fertilizer dryer. Background technique

[0002] The current method of fertilizer production is basically high-tower granulation, so fertilizers are mostly spherical granules. During high-tower granulation, various raw materials need to be mixed to make slurry, sprayed down from the top of the high tower, and then cooled to become For spherical granular fertilizers, in order to facilitate the storage and transportation of fertilizers, the moisture inside the fertilizer particles needs to be removed by a dryer.

[0003] Most of the traditional fertilizer dryers are drum dryers, which are repeatedly stirred by the lifting plate to make the granular fertilizer fully contact with the hot air to achieve the purpose of drying. However, the rotation direction of the drum dryer and the stirring method of the lifting plate Single, the lifting effect is poor, it...
