Microbial fertilizer vertical wind tunnel granulation blanking system and method

Abstract

The invention relates to a microbial fertilizer vertical wind tunnel granulation blanking system and method. The microbial fertilizer vertical wind tunnel granulation blanking system comprises a raised granulation preparation building and a discharging conveying belt arranged on one side of the top of the raised granulation preparation building and communicated with the interior of the raised granulation preparation building. A rotary rolling receiving hopper is arranged below the end of the discharging conveying belt in a bearing mode. The bottom of the rotary rolling material receiving hopper is connected with a wind tunnel granulation device, and a material receiving platform is arranged at the bottom of the wind tunnel granulation device. According to the invention, particles can be rapidly air-cooled, air is blown from bottom to top through the wind tunnel effect, the wind speed and wind power are accurately calculated according to the particle size of the particles, and wind tunnel cooling operation is effectively carried out while slow discharging is guaranteed; and the produced and prepared particles are uniformly and dispersedly discharged into a vertical cylinder at the bottom by utilizing a rotary discharging hopper type structure at the top, so that the particles at the top are prevented from being adhered, and meanwhile, top scattering and discharging operation is provided for the vertical cylinder of a wind tunnel structure.

Description

technical field [0001] The invention relates to the field of microbial fertilizer preparation, in particular to a microbial fertilizer vertical wind tunnel granulation blanking system and method. Background technique [0002] Microbial fertilizer is a biological fertilizer produced by industrialized cultivation and fermentation of one or several beneficial microorganisms. Microbial fertilizers are usually divided into two categories: one is through the life activities of the microorganisms contained in it, which increases the supply of plant nutrients, leads to the improvement of plant nutrition, and then increases the yield. The representative variety is bacterial fertilizer; the other The category is microbial fertilizer in a broad sense. Although it also increases crop production through the microbial life activities contained in it, it is not limited to improving the supply level of plant nutrients, but also includes secondary metabolites produced by them, such as hormon...

AI Technical Summary

Problems solved by technology

However, microbial fertilizers have their own characteristics. When encountering high temperatures, their internal reactions are prone to change, resulting in the characteristics of the fertilizer picking up the original effect. However, the traditional air-cooling operation cannot satisfy the fast and efficient air-drying operation.
