Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0019] A production device for heterogeneous variable-speed controlled-release fertilizer without secondary blending, comprising a reactor 1, a metering pump 2, a solenoid valve 3, a nozzle 4, a drum 15, a lifting plate 13 and a blending device. The drum is divided into five sections, from left to right are the coating area 5, the first replacement area 7, the transition area 9, the second replacement area 11 and the synthesis area 12. In the first replacement area, the transition area, the second replacement area and the synthesis area, there are fixed lifting plates at uniform intervals in the radial direction. There are three nozzles installed in the coating area, and each nozzle is respectively c...

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...
