Drying device for bio-organic fertilizer

Abstract

The invention relates to the technical field of organic fertilizer drying, and especially relates to a drying device for a bio-organic fertilizer. The drying device for the bio-organic fertilizer comprises a drying cylinder which is vertically arranged, wherein a material guide plate is arranged in the drying cylinder and above a drying air inlet port, and the material guide plate inclines towards the upper right side; a plurality of ventilation ports are formed in the material guide plate, an auger piece is arranged in the drying cylinder and between the material guide plate and a charging port, an electromagnetic heating sleeve is arranged outside the lower portion of the middle of the drying cylinder, raw materials enter from the upper portion of one side of the drying cylinder during drying, and airflow flowing upwards exists in the drying cylinder; the organic fertilizer is dried and screened under the action of relative movement of the airflow and the granular organic fertilizer, powder is light, and enters a cyclone recovery device to be separated under the driving of the airflow, and the granular organic fertilizer is heavy, rolls downwards along the auger piece, and then is discharged from a discharging port in the lower portion of one side; and screening work is realized during drying, so that high working efficiency is achieved, and organic fertilizer grains cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer drying, in particular to a biological organic fertilizer drying device. Background technique [0002] The processing of commercial organic fertilizer requires two steps: the pre-fermentation part and the processing and granulation part. Bio-organic fertilizer equipment needs fermentation turning machine, organic fertilizer pulverizer, drum screening machine, horizontal mixer, organic fertilizer granulator, rotary dryer, cooling machine, screening machine, coating machine, packaging machine, conveyor machines and other equipment. [0003] However, the existing organic fertilizer drying device still has certain defects: the existing drying machine is a drum drying device, and the internal organic fertilizer particles are turned over and fried by the rotation of the drum. During the feeding process, the organic fertilizer particles collide with each other, and when the organic fertilizer...

Problems solved by technology

[0003] However, the existing organic fertilizer drying device still has certain defects: the existing drying machine is a drum drying device, and the internal organic fertilizer particles are turned over and fried by the rotation of the drum. During the feeding process, the organic fertilizer particles collide with each other, and when the organic fertilizer particles collide with the inner wall of the drying drum when the organic fertilizer particles fall, they will cause damage to the granular organic fertilizer. There are many powder raw materials, and when they are screened by a vibrating sieve, the granular organic fertilizer is traumatized again, which seriously affects the production quality of organic fertilizer
