adding amino acid stock solution (discharged from a stock solution storage tank 1) and solid trace element compounds (fed at a certain feeding speed by a spiral electronic scale 7) into the circulating dissolving and feeding tank 2 in proportion, starting a mechanical stirrer in the circulating dissolving and feeding tank 2, dissolving and mixing the amino acid stock solution and the trace element compounds in the tank, and discharging the mixture into a chelating tank 3; the unidirectional breather valve replenishes air outside the tank into the tank, and when the pressure in the tank is higher than the pressure outside the tank, gas is continuously discharged through a pressure reducing valve on the top of the tank, and the circulating dissolving feeding tank 2 is communicated with the deodorization pipeline;
the liquid fertilizer which is completely reacted in the chelating tank 3 is discharged into a finished product storage tank, the liquid fertilizer is the same as the raw liquid storage tank 1, the temperature of materials in the finished product storage tank 4 is adjusted through a vent pipe 9, the air pressure is adjusted through a bidirectional breather valve, and a deodorization system processes air discharged from the finished product storage tank 4.
The production method of example 2 is based on example 1, with the difference that the amino acid stock solution entering the stock solution storage tank is first subjected to rough filtration; the liquid fertilizer discharged from the bottom of the chelating tank 3 is subjected to fine filtration. When the coarse filtering equipment and the fine filtering equipment are blocked, the filtered materials are led out for backflushing.
The production method of example 3 is the same as example 1.
Example 4 during operation, the discharge of circulation dissolving feeding tank 2 is led into a plurality of chelating tanks 3, and a plurality of chelating tanks 3 and circulation dissolving feeding tank 2 respectively form an internal circulation. Example 4 meets the requirements of large-scale production based on the same capacity of the chelation tank 3 and the recycle dissolution feed tank 2.
The amino acid liquid fertilizer introduced into the product tank 4 in examples 1 to 4 was further introduced into a packaging line.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
