Intelligent preparation system and intelligent preparation method of liquid slowly-controlled-release fertilizer

Abstract

The invention discloses an intelligent preparation system and method for a liquid slow-controlled release fertilizer. The induction module senses whether the weight of each raw material reaches a predetermined value, the temperature detection module detects the temperature value in the stirring device 4, and the wind measuring module measures the stirring device 4. The ventilation degree inside, and the pH detection module detects the pH value of the solution; PLC controls the solenoid valve, grinding module, stirring module, sugar-water ratio module, Blast module, temperature control module, wind measurement module, prompt module, heating module, material module, refrigeration module, drying module, crushing module, filter module, vibration module, concentration module and cooling module perform related operations; The precise control of the parameters can effectively improve the stability of its slow-release trace element chelating agent and slow-release microcrystalline metal salt ore powder; it has high production efficiency, meets the production rhythm, reduces labor intensity, and has accurate and reliable detection.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an intelligent preparation system and method for liquid slow and controlled release fertilizers. Background technique [0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers Sexuality and volatility. The corresponding measures are to use slow-release coated fertilizers to improve nutrient utilization, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and there is no specificity. The demand for nutrients restricts its own development. [0003] At the same time, in the preparation process of fertilizers, slow-release microbial agents, slow-release trace element chelating age...

[0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers volatile and volatile

The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, untargeted, and the demand for nutrients restricts its own development.

[0003] At the same time, in the preparation process of fertilizers, slow-release microbial agents, slow-release trace element chelating agents, and slow-release microcrystalline metal salt ore powder all play an indispensable role, directly affecting the quality and nutrients of fertilizers; If it is a mass production, the slow-release microbial agent, slow-release trace element chelating agent and slow-release microcrystalline metal salt ore powder also need to be produced in large quantities, but at this stage, the slow-release microbial agent, slow-release trace element The preparation of chelating agent and slow-release microcrystalline metal salt ore powder mostly relies on manual operation, which has low efficiency and low degree of automation, which brings inconvenience to operation and wastes resources
