A production device for heterogeneous variable-speed controlled-release fertilizer without secondary blending

Abstract

The invention relates to a controlled-release fertilizer special particle speed changing device without secondary mixing. The controlled-release fertilizer special particle speed changing device comprises a reaction kettle, a metering pump, an electromagnetic valve, spray nozzles, a roller and a mixing device, wherein a plurality of spray nozzles are mounted at one end of the roller, each spray nozzle is respectively connected with the reaction kettle through the electromagnetic valve and the metering pump, the mixing device is coaxially mounted in the middle part of the roller, the mixing device is shaped like a trumpet which is large at one end and small at one end, the two ends are respectively fixed on the inner wall of the roller through a suspending frame, the large end faces the end of the spray nozzles, hoppers are uniformly distributed at the small end of the mixing device in the radial direction, the bottom end of each hopper is hinged with a movable bottom, and a color iron is fixedly arranged on the inner side of each movable bottom. The device can simultaneously produce a variety of different controlled-release fertilizers with different release rates, uniform mixing is realized in the device, the secondary mixing is not required, the process flow is shortened and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fertilizers and relates to controlled-release fertilizers, in particular to a production device for different-grain variable-speed controlled-release fertilizers without secondary mixing. Background technique [0002] Controlled-release fertilizer is to prolong the decomposition and release time of fertilizer by coating, wrapping, adding inhibitors, etc., which is conducive to improving the utilization rate of fertilizer nutrients, so as to achieve the purpose of extending the validity period of fertilizer and promoting agricultural production. Each particle is wrapped with a layer of biodegradable organic resin coating, through which the controlled release of nutrients is achieved, that is, the release of nutrients is automatically adjusted according to the needs of the plants, that is, insufficient release will not cause poor growth of plants due to lack of nutrients, nor Excessive release will cause nutrient los...
