Description

Technical Field

[0001] This invention relates to a blended fertilizer production system with a quantitative continuous feeding function, belonging to the field of blended fertilizer production technology. Background Technology

[0002] Blended fertilizers, also known as formulated fertilizers or BB fertilizers, are made by mixing two or more single-element or compound fertilizers with similar particle sizes in a certain proportion using simple mechanical methods. They are mixtures of various raw materials. The advantages of blended fertilizers include simple production processes, flexible operation, lower production costs, and nutrient ratios adapted to micro-regional regulation or the specific needs of crops in specific fields. Compared to compound fertilizers, blended fertilizers have unique advantages in production, storage, and application.

[0003] Microbial inoculants are preparations containing a large number of beneficial microorganisms that can improve soil structure, enhance soil fertility, and inhibit the growth of pathogens. Blended fertilizers, on the other hand, are compound fertilizers made by mixing various single-element fertilizers according to crop needs; they provide comprehensive nutrients and are easily absorbed by crops.

[0004] Using microbial inoculants and blended fertilizers together can fully leverage the advantages of both. Microbial inoculants can activate the soil and improve the availability of nutrients, while blended fertilizers provide crops with all the nutrients they need. Using them together can meet the nutrient requirements of crops and improve the soil environment, which is beneficial for long-term crop growth. However, current technology is not comprehensive and has the following drawbacks: the microbial solution to be diluted cannot be fully mixed with the base solution in the dilution mixing tank, resulting in poor product uniformity; and currently, it is impossible to spray and adsorb the liquid microbial inoculant onto the blended fertilizer granules, making it unsuitable for compounding microbial inoculants and blended fertilizers.

[0005] To solve one of the above problems, there is an urgent need for a blended fertilizer production system with a quantitative and continuous feeding function. Summary of the Invention

[0006] Based on the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to spray the diluted bacterial solution onto the blended fertilizer particles on the blended fertilizer conveyor belt through the mixed liquid outlet pipe, pipeline mixer, and spray gun, so that the liquid microbial agent can be sprayed and adsorbed onto the blended fertilizer particles for compounding of microbial agent and blended fertilizer. To this end, a blended fertilizer production system with quantitative continuous feeding function is provided.

[0007] The blended fertilizer production system with quantitative continuous feeding function of the present invention includes a bacterial solution dilution and mixing tank. A first bent pipe is connected to the inlet at the bottom of the bacterial solution dilution and mixing tank, and a second bent pipe is connected to the outlet at the top of the bacterial solution dilution and mixing tank. The system is characterized in that: the other end of the first bent pipe is connected to a base liquid inlet pipe, the other end of the second bent pipe is connected to a pipeline mixer, and the other end of the pipeline mixer is connected to a mixed solution outlet pipe. Multiple sets of internal partitions are spaced apart inside the bacterial solution dilution and mixing tank, dividing the inner cavity of the tank into multiple mixing chambers. Each mixing chamber is equipped with two sets of stirring mixers. A bacterial agent supply system is connected to the supply port of the stirring mixer. A spray gun is connected after the mixed solution outlet pipe. The bacterial agent spraying system is located above the conveying path of the blended fertilizer conveyor belt, using the spray gun to spray and adsorb liquid microbial agents onto the blended fertilizer particles. The mixed solution outlet pipe has an electrically controlled regulating valve to control the flow rate.

[0008] This invention utilizes a base liquid inlet pipe to inject base liquid into a bacterial solution dilution and mixing tank, and injects the bacterial solution to be diluted into the tank through a first and second agitator.
