Embodiment 1

[0014] A cooling device in the production of water-soluble ammonium polyphosphate, comprising a product discharge bin 1 and a finished product packaging bin 3, a scraper machine 2 is arranged between the product discharge bin 1 and the finished product packaging bin 3, and the scraper machine 2 is outsourced Covered with circulating water cooling jacket.

Embodiment 2

[0016] A cooling device in the production of water-soluble ammonium polyphosphate, comprising a product discharge bin 1 and a finished product packaging bin 3, a scraper machine 2 is arranged between the product discharge bin 1 and the finished product packaging bin 3, and the scraper machine 2 is outsourced Covered with circulating water cooling jacket. The scraper machine 2 is composed of two sections, the one connected to the product discharge bin 1 is a horizontal section, and the one connected to the finished product packaging bin 3 is an inclined section, and the angle α between the horizontal section and the inclined section is 30-80°

Embodiment 3

[0018] A cooling device in the production of water-soluble ammonium polyphosphate, comprising a product discharge bin 1 and a finished product packaging bin 3, a scraper machine 2 is arranged between the product discharge bin 1 and the finished product packaging bin 3, and the scraper machine 2 is outsourced Covered with circulating water cooling jacket. The scraper machine 2 is composed of two sections, the one connected to the product discharge bin 1 is a horizontal section, and the one connected to the finished product packaging bin 3 is an inclined section, and the angle α between the horizontal section and the inclined section is 30-80°. The horizontal section is composed of two layers, the upper layer is connected to the product discharge bin 1, and the lower layer is connected to the inclined section after turning.

[0019] The product discharge bin 1 undertakes the production of synthetic ammonium polyphosphate, the temperature of which is 120-180°C. The ammonium polyp...

Abstract

The invention discloses a cooling device in production of water-soluble ammonium polyphosphate. The cooling device comprises a product discharging bin and a finished product packaging bin, wherein a plate scraper is arranged between the product discharging bin and the finished product packaging bin, and a circulating water cooling jacket coats the plate scraper. The cooling device in the production of the water-soluble ammonium polyphosphate, disclosed by the invention, has a simple structure, and solves the problem that the products cannot be directly packaged for excessive temperature when materials of the products are discharged in the production of the water-soluble ammonium polyphosphate.

Description

technical field [0001] The invention belongs to the field of fertilizer production, and in particular relates to a cooling device in the production of water-soluble ammonium polyphosphate. Background technique [0002] Ammonium polyphosphate, also known as ammonium polyphosphate or polycondensed ammonium phosphate, ammonium polyphosphate with a degree of polymerization usually less than 20 has good water solubility. Ammonium polyphosphate contains nitrogen and phosphorus elements needed for plant growth, and has a certain chelating effect on metal ions. As a high-concentration fertilizer with slow-release and chelating effects, water-soluble ammonium polyphosphate has gradually entered the field of fertilizers. [0003] However, in the synthesis process of ammonium polyphosphate, the reaction temperature of the material is often higher than 100°C or even higher, and the temperature of the product when it is discharged is generally higher than 100°C. If the subsequent cooling...
