Description

Technical Field

[0001] This utility model relates to the field of fertilizer processing equipment technology, and specifically discloses a multi-layer coating granulator for a ternary slow-release fertilizer containing enzymes and mycotoxins. Background Technology

[0002] The multi-layer coating granulator for enzyme-microbe-peptide ternary slow-release fertilizer is an intelligent device specifically designed for the production of functional slow-release fertilizers. Its core function is to use physical isolation technology to coat three types of active ingredients (microbial agents, enzyme preparations, and peptides) in a specific order onto the surface of fertilizer granules, thereby achieving precise controlled release in the field.

[0003] Existing slow-release fertilizer coating machines mostly use single-layer or double-layer spraying, which makes it difficult to achieve targeted, layered coating of active ingredients (such as microbial agents, enzymes, and peptides). Traditional equipment suffers from problems such as interlayer penetration of the coating, inactivation of active ingredients, and short duration of effect, and in particular, it cannot meet the temperature-sensitive requirements of microbial and enzyme preparations. Utility Model Content

[0006] The multi-layer coating mechanism includes vertical plates fixedly connected to the inside of the housing and distributed left and right. A first rotating cylinder, a second rotating cylinder, a third rotating cylinder, and a fourth rotating cylinder distributed vertically are rotatably connected between the two vertical plates. A cooling cylinder is installed inside the fourth rotating cylinder. The two ends of the first rotating cylinder, the second rotating cylinder, the third rotating cylinder, and the fourth rotating cylinder extend to the other side of the two vertical plates, respectively.

Multiple evenly distributed nozzles are fixedly connected to the outer walls of the first conveying pipe, the second conveying pipe, and the third conveying pipe.

[0007] In a preferred embodiment of the multi-layer coating granulator for the enzyme-peptide ternary slow-release fertilizer of this utility model, the outer walls of the first, second, third, and fourth rotating drums are all fixedly connected with first gears, and multiple drive motors are installed on the opposite side walls of the two vertical plates.

The first rotating drum 3, second rotating drum 4, third rotating drum 5, and fourth rotating drum 6 then rotate. After the fertilizer granules enter the first rotating drum 3, the rotation of the first rotating drum 3 causes the fertilizer granules to tumble. Simultaneously, the Bacillus subtilis suspension is evenly sprayed onto the outer surface of the fertilizer granules through the first conveying pipe 11 and multiple nozzles 14. The fertilizer granules in the first rotating drum 3 are then discharged from the right end of the first rotating drum 3 and conveyed through the guide chute 18 to the second rotating drum 4.

The enzyme preparation microcapsule slurry is evenly sprayed onto the outer surface of the fertilizer granules, and then the fertilizer granules are conveyed to the third rotating drum 5 through the feeding trough 18. Through the cooperation between the third rotating drum 5 and the third conveying pipe 13, the soybean polypeptide solution is evenly sprayed onto the outer surface of the fertilizer granules, and then the fertilizer granules are conveyed to the fourth rotating drum 6 through the feeding trough 18. At the same time, the interior of the fourth rotating drum 6 is cooled by the cooling cylinder 10. The Bacillus subtilis suspension, enzyme preparation microcapsule slurry, and soybean polypeptide solution are rapidly cooled and solidified by the low temperature, and then discharged into the discharge trough 9 through the left end of the fourth rotating drum 6, and then discharged from the box 1 through the discharge trough 9. This completes the multi-layer coating of the fertilizer granules, thereby achieving gradient coating of the inner, middle and outer layers, and extending the field retention period of the active ingredients.

[0023] As a technical optimization of this utility model, the outer walls of the first rotating drum 3, the second rotating drum 4, the third rotating drum 5 and the fourth rotating drum 6 are all fixedly connected with first gears 15, and multiple drive motors 16 are installed on the opposite side walls of the two vertical plates 2.

[0027] As a technical optimization of this utility model, a granulator body 19 is installed on the upper end face of the box 1. The granulator body 19 and the box 1 are connected by a feed pipe 7. The lower end of the feed pipe 7 is located directly above the uppermost guide trough 18.

[0028] In this embodiment: the granulator body 19 can granulate the fertilizer, and the processed fertilizer granules can be transported into the box 1 through the feed pipe 7.

[0029] As a technical optimization of this utility model, one end of the first conveying pipe 11, the second conveying pipe 12 and the third conveying pipe 13 all extend to the outside of the box body 1 and are equipped with quick-release connectors 8.

[0030] In this embodiment, multiple quick-release connectors 8 facilitate the connection of the first delivery pipe 11, the second delivery pipe 12, and the third delivery pipe 13 to external pipes.

[0031] As a technical optimization of this utility model, the lower end face of the box 1 is connected to the discharge chute 9 located directly below the left end of the fourth rotating drum 6.

Simultaneously, the fertilizer granules are conveyed through the first conveying pipe 11 and multiple...

Then, the fertilizer granules in the first rotating drum 3 are discharged from the right end of the first rotating drum 3 and conveyed to the second rotating drum 4 through the guide trough 18. Through the cooperation between the second rotating drum 4 and the second conveying pipe 12, the enzyme preparation microcapsule slurry is evenly sprayed onto the outer surface of the fertilizer granules. Then, the fertilizer granules are conveyed to the third rotating drum 5 through the guide trough 18. Through the cooperation between the third rotating drum 5 and the third conveying pipe 13, the soybean polypeptide solution is evenly sprayed onto the outer surface of the fertilizer granules. Then, the fertilizer granules are conveyed to the fourth rotating drum 6 through the guide trough 18. At the same time, the interior of the fourth rotating drum 6 is cooled by the cooling cylinder 10. The Bacillus subtilis suspension, enzyme preparation microcapsule slurry, and soybean polypeptide solution are rapidly cooled and solidified by low temperature. Then, they are discharged into the discharge trough 9 through the left end of the fourth rotating drum 6 and discharged from the box 1 through the discharge trough 9, thus completing the multi-layer coating of the fertilizer granules.
