Problems solved by technology

The fertilizer granules produced by the existing high-tower granulation method are uneven in size, raindrop-shaped, and not round, and some fertilizer granules are not completely cooled during the falling process, resulting in easy agglomeration and dissolution of the produced fertilizer granules. Quality is not guaranteed, pass rate is not high

Abstract

The invention discloses a circular particle high tower granulation method and a double-layer ventilation material receiving device thereof, and belongs to the technical field of compound fertilizer granulation equipment. The material receiving device mainly comprises an upper material receiving table, a ventilation blanking port and a spiral material receiving mechanism matched with the ventilation blanking port are arranged on the upper material receiving table, a lower material receiving table is arranged at the bottom of the upper material receiving table, a strip-shaped discharging port is formed in the lower material receiving table, a central ventilation hole is formed in the middle of the lower material receiving table, and a slewing bearing is arranged at the central ventilation hole. A fixed ring of the slewing bearing is fixedly connected with the lower material receiving table, a slewing ring of the slewing bearing is matched with the output end of the driving mechanism, and more than one slewing scraper matched with the upper surface of the lower material receiving table is arranged on the slewing ring of the slewing bearing. According to the method, air is continuously fed from the bottom of the high tower to the top of the high tower, so that cooling of the chemical fertilizer slurry is accelerated, part of gravity of the chemical fertilizer slurry during falling is relieved, and condensed chemical fertilizer particles are changed into spherical structures from raindrop structures.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer granulation equipment, and in particular relates to a round granule high tower granulation method and a double-layer ventilation and material receiving device. Background technique [0002] In the fertilizer processing industry, the high-tower granulation process is usually used for granulation, that is, the fertilizer is melted into a liquid state at the top of a tower with a diameter of 12-19 meters and a height of 80-130 meters, and then sprayed from the top of the tower. During the falling process, the liquid fertilizer gradually cooled and condensed into small solid particles, the shape of which was like raindrops. Finally, the falling fertilizer granules fall at the bottom of the tower, and are collected by the feeder. The fertilizer granules produced by the existing high-tower granulation method are uneven in size, in the shape of raindrops, the granules are not round, and some...
