Drying device for fertilizer

Abstract

The invention discloses a drying device for a fertilizer, and relates to the technical field of fertilizer processing. The drying device for the fertilizer comprises a stable bottom plate, wherein a dustproof protection cover is fixedly mounted at the top of the stable bottom plate; and a first drying cylinder and a second drying cylinder are arranged between the stable bottom plate and the dustproof protection cover. According to the drying device for the fertilizer, in the drying process of the device, the first drying cylinder, the second drying cylinder and a cylindrical elastic film are in a rotating state all the time, a hard steel bar fixedly embedded in the cylindrical elastic film can ascend and descend under the action of a pushing block, meanwhile, the part, in contact with the pushing block, of the cylindrical elastic film can be stretched and deformed, the fertilizer attached to the inner wall of the cylindrical elastic film can be separated from the cylindrical elastic film under the deformation of the cylindrical elastic film, and the fertilizer can roll in the cylindrical elastic film in the rotating process of the cylindrical elastic film, so that the fertilizer can be prevented from being attached to the inner wall of the cylindrical elastic film, and meanwhile, the drying effect of the fertilizer can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a drying device for fertilizer. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, macroelement water-soluble fertilizers, medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. According to the physical state of fertilizer, it can be divided into solid and liquid fertilizer. Solid fertilizers are further divided into powdery and granular fertilizers. Fluid fertilizer is a fertilizer that is in a liquid state at normal temperature and pressure. [0003] When storing powdered fertilizer in an area with high air humidity, th...

Problems solved by technology

However, this treatment method is easy to cause the dried fertilizer to adhere to the inner wall of the heating device. If the fertilizer adheres to the inner wall of the heating device, it will not only make it difficult to clean the heating device, but also cause the heating device to not be in direct contact with other fertilizers, resulting in the heating effect of the heating device. bad
