Production device and production method of double slow release high dispersion medicinal fertilizer

Abstract

The present invention relates to a production device and a production method of a double slow release high dispersion medicinal fertilizer; the production device includes a urea solution pipeline, theurea solution pipeline is connected with a granulation system through a third valve, a fourth flow meter, a first inlet and an outlet of a pipeline mixer, the second inlet of the pipeline mixer is connected with a medicinal fertilizer emulsifying device; the medicinal fertilizer emulsifying device includes a pesticide tank which is connected with one side of the top of an emulsifying tank, a solvent tank is connected with the other side of the top of the emulsifying tank, an emulsifying tank motor is arranged at the middle of the top of the emulsifying tank, an emulsifying tank outlet is connected with the inner chamber of a nozzle through a solution pump, the nozzle is arranged on the lower middle part of a fluidized bed reactor, a middle powder inlet of the fluidized bed reactor is connected with a fertilizer carrier tank by a powder pump, a material outlet at the bottom of the fluidized bed reactor is connected with the second inlet of the pipeline mixer, a pesticide can be evenlydistributed inside a fertilizer without direct contact with the fertilizer, the compatibility effect of the pesticide and the fertilizer is overcome, and the purpose of unified double slow release ofthe pesticide and the fertilizer can be achieved.

Description

technical field [0001] The invention belongs to the technical field of double slow-release high-dispersion fertilizer production, and in particular relates to a double slow-release high-dispersion fertilizer production device and a production method. Background technique [0002] Medicinal fertilizer is a formulation of pesticides and fertilizers in a certain proportion, which is stabilized in a specific compound system after certain processing technology, so that the two operation steps in the field can be combined into one, saving labor, time and energy, and reducing agricultural production costs. At present, the production methods of medicinal fertilizers are roughly divided into mixing method, soaking method and coating method. Although this kind of method has played the double effect of fertilizer and pesticide, but in above-mentioned method, pesticide is all directly contacted with fertilizer, has compatibility effect problem, causes available pesticide kind to be limi...

AI Technical Summary

Problems solved by technology

Although this kind of method has played the double effect of fertilizer and pesticide, but in above-mentioned method, pesticide is all directly contacted with fertilizer, has compatibility effect problem, causes available pesticide kind to be limited; In addition, this kind of production method also has other defects, For example: the soaking method is to soak the fertilizer particles into the pesticide solvent, and obtain the product by recycling the solvent. Due to the limited amount of pesticides and solvents, the amount of soaking into the fertilizer is less, and the cost of solvent recovery is high, so its application range is small; Covering method: Pesticides only exist outside the fertilizer. At the same time as the fertilizer disintegrates, the pesticides are released at an early stage. Therefore, in order to meet the duration of pesticides, the fertilizers produced by this process tend to choose high-residue fertilizers with a long degradation cycle. Pesticides have potential environmental safety risks. In addition, when the coating method is used to produce medicinal fertilizers, the equipment is relatively open and lacks airtight measures. The produced medicinal fertilizers and pesticides are directly exposed on the surface of the fertilizers. Farmers lack awareness of protection when applying them. There are potential production occupational health risks and Use of security risks

Although the above method has solved some problems, there are still problems such as narrow product application and potential safety hazards in production and use, which is not conducive to large-scale industrial production
