The production method of the continuous inorganic coated functional fertilizer effectively solves the disadvantages of intermittent production and realizes automatic operation.

Description

Production method of continuous inorganic coated functional fertilizer

Technical Field

The invention relates to the technical field of chemical fertilizer processing, in particular to a production method of a continuous inorganic coated functional fertilizer.

Background

The functional fertilizer is simple in terms of functions, and can meet the requirements of different plants in different growth stages, such as a flower and fruit protecting fertilizer, a root growth promoting fertilizer, a soil improving fertilizer, a fruit swelling and coloring fertilizer and the like with certain functions, or a fertilizer integrating multiple functions, such as a self-contained nutrient biological bacteria flush fertilizer capable of improving and activating soil, and simultaneously has the functions of loosening soil, rooting and strengthening seedlings, eliminating harmful germs, improving the utilization rate of the fertilizer, promoting fruit swelling and coloring, and improving yield and quality.

The current market wrapping fertilizer mainly adopts a disc intermittent production mode as a main mode. Has the defects of high energy consumption, large environmental protection pressure, unstable product performance and incapability of continuous production.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a production method of a continuous inorganic coated functional fertilizer.

The technical scheme adopted by the invention for solving the technical problems is as follows: a production method of a continuous inorganic coated functional fertilizer comprises the following steps:

step 1, after the core particle materials are measured, inputting the core particle materials into a roller granulator through a belt;

step 2, spraying the phosphoric acid on the surface of the granular core material after metering by a metering pump, and uniformly mixing the granular core material and the phosphoric acid;

3, turning the uniformly mixed particle core material and phosphoric acid mixture through a first check ring, entering a space between the first check ring and a second check ring, and carrying out acid-base neutralization reaction with the weighed alkaline reaction material;

step 4, the particle mixture after the acid-base neutralization reaction enters the next check ring until the rest materials are added in proportion;

and 5, screening the processed functional fertilizer material by a cooling machine, metering and packaging, and finally warehousing.

Specifically, the phosphoric acid may be replaced by other mixed acids.

The invention has the beneficial effects that:

the production method of the continuous inorganic coated functional fertilizer effectively solves the disadvantages of intermittent production, realizes automatic operation, greatly improves the field operation environment, is beneficial to the physical health of workers, has more stable performance and more remarkable effect, greatly saves social resources and is beneficial to upgrading and reconstruction of the whole industry.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in figure 1, the production method of the continuous inorganic coated functional fertilizer comprises the following steps:

step 1, after the core particle materials are measured, inputting the core particle materials into a roller granulator through a belt;

step 2, spraying the phosphoric acid on the surface of the granular core material after metering by a metering pump, and uniformly mixing the granular core material and the phosphoric acid;

3, turning the uniformly mixed particle core material and phosphoric acid mixture through a first check ring, entering a space between the first check ring and a second check ring, and carrying out acid-base neutralization reaction with the weighed alkaline reaction material;

step 4, the particle mixture after the acid-base neutralization reaction enters the next check ring until the rest materials are added in proportion;

and 5, screening the processed functional fertilizer material by a cooling machine, metering and packaging, and finally warehousing.

The whole process of the method needs 1-3 feeding cycles, acid-base reaction is carried out in the process, a large amount of heat is released, the temperature of materials is raised, meanwhile, partial water in acid liquor is evaporated, and the excess water is automatically treated by means of a technology of converting free water into crystal water.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
