Biofertilizer cooling device

Abstract

The invention discloses a biofertilizer cooling device which comprises a stirring and cooling system composed of a cooling box, a discharging box, a servo motor, a main stirrer, an auxiliary stirrer and an air cooler, a feeding and mixing system composed of a feeding pipe and a feeding pump, and a screening and discharging system composed of an inclined vibrating screen, a first conveyor belt anda second conveyor belt. The discharging box is welded to the bottom end of the discharging box, and a feeding hopper communicates to one side of the top end of the cooling box. The cooling device stirs and mixes a fertilizer through double stirrers, cold air blown by the air cooler is exported through an air outlet hole and is fed into the fertilizer along with rotation of the stirrers to cool thefertilizer from inside to outside, the fertilizer exported from a material guide port is pre-screened by the inclined vibrating screen, and two fertilizers of different levels are fed to different positions through the first conveyor belt and the second conveyor belt to be screened again. In the pre-screening process, an air outlet hopper is aligned to the inclined vibrating screen to blow cold air to cool the fertilizer thereon again.

Description

Technical field [0001] The invention relates to the technical field of biological fertilizer production equipment, in particular to a biological fertilizer cooling device. Background technique [0002] Existing biological fertilizers are all based on organic matter, and then mixed with bacteria and inorganic fertilizers. In order to widely improve this general and traditional situation, bio-fertilizer products go far beyond the existing concept. It will be expanded to not only provide crop nutrition, but also improve the soil; at the same time, it should also disinfect the soil, that is, use organisms (mainly microorganisms) to decompose and eliminate pesticides (insecticides and fungicides), herbicides, and Pollutants from products such as petrochemicals, and at the same time play a role in repairing the soil. [0003] Biological fertilizer in a narrow sense refers to microbial (bacterial) fertilizer, referred to as bacterial fertilizer, and also known as microbial inoculant. I...

AI Technical Summary

Problems solved by technology

[0005] The production of biological fertilizer needs to go through the processing process of batching→mixing→granulation→drying→cooling→sieving→packaging. During the cooling process, due to the large amount of biological fertilizer, the cooling device cools the fertilizer in the box through the cooling fan. The cold air blown by the air cooler intelligently cools the fertilizer on the surface, but the cooling area of ​​the internal fertilizer is limited, and there is often a phenomenon of external cooling and internal heat, which has the problems of poor cooling quality and low work efficiency, which is not conducive to the subsequent screening work
