Embodiment 1

[0021] Such as figure 1 As shown, the direct flushing spraying granulation dryer includes a drying body 8, and a feeding bin 2 is provided on the side of the drying body 8. High-pressure air pipe 1.1, baffle plate 18, anti-material spiral body 9 and material plate 10 are provided on the inner wall of the drying body; a grading cone 11 is provided at the tail of the drying body 8, and a hot air system 3 is provided at the top of the drying body 8, and the hot air system 3 includes Vertically downward fine material injection port 6, the lower part of the fine material injection port 6 is provided with a screw chamber 5, the lower part of the screw chamber 5 is provided with a fine material outlet 7, and the side part of the spiral chamber 5 is provided with a heat blower that can blow air to the spiral chamber. The fan 4 and the fine material outlet 7 are facing the granulation spray gun 1.

[0022] The rear position of the grading cone 11 is also provided with a rotary screen,...

Embodiment 2

[0025] In this embodiment, the difference from embodiment 1 is that the sharpness of the blower 1 is 0.5 times the power of the hot air blower, and the rest of the working principles are the same as in embodiment 1.

Abstract

The invention discloses a direct jet type slurry spraying granulation drier. The drier comprises a drier body, the drier body side is provided with a feeding bin, a granulation spray gun traverses through the central position of the feeding bin, the tail portion of the drier body is provided with a grading awl, the top of the drier body is provided with a hot air system, the hot system comprises a vertical downward fine material spraying hole, the lower portion of the fine material spraying hole is provided with a spiral bin, and the side portion of the spiral bin is provided with a hot air fan blowing the spiral bin, the lower portion of the spiral bin is provided with a fine material outlet, and the fine material outlet rightly faces the granulation spray gun.

Description

technical field [0001] The invention relates to compound fertilizer production equipment, in particular to a direct flushing spraying granulation dryer. Background technique [0002] At present, the existing main equipment for the production of compound fertilizers includes disc granulation equipment and roller compaction granulation equipment, etc., and the latest compound fertilizer production equipment also includes liquid spray granulation equipment, which passes through the granulator Add steam and water to the raw materials, add acid and ammonia to neutralize and carry out acid granulation, and make a compound fertilizer with qualified nutrients and qualified appearance. In addition, the granulator and dryer are essential equipment in the production process of compound fertilizer. The granulator is mainly used to squeeze the finished or semi-finished fertilizer, which has reached the product quality requirements. The dryer is used to granulate The materials produced i...
