Composite fertilizer particle granulation apparatus

Abstract

The invention provides a composite fertilizer particle granulation device, which comprises a composite particle melting component, a particle forming component, and a rotary metal cooling conveyor. The composite particle melting component comprises an ammonnium phosphor nitrate melting chamber, an auxiliary material mixing bin, an auxiliary material crusher, a heater, and a mixer, the ammonnium phosphor nitrate melting chamber is connected to the mixer through a pump, the auxiliary material mixing chamber is connected with the auxiliary material crusher, the auxiliary material crusher is connected with the heater, and the heater is connected with the mixer; a servo motor on a sliding rod is arranged at the particle forming component, the servo motor is provided with a nozzle, and the nozzle is connected with the mixer; the rotary metal cooling conveyor comprises a main driving wheel and a steering wheel, the main driving wheel and the steering wheel are sleeved with a metal belt, a stepping motor is mechanically coupled to the main driving wheel, and the surface of the metal belt is provided with particle holes. The invention has the advantages that the composite fertilizer particles are naturally cooled and formed, and only the appropriate path is needed to reduce the pollution of the dust and the exhaust gas in the production.

Description

technical field [0001] The invention relates to a compound fertilizer granule manufacturing device, in particular to a compound fertilizer granule granulation device without dust pollution. Background technique [0002] At present, the production equipment and production technology of the domestic compound fertilizer production industry are varied, and the elements contained in the products are also different, which are difficult to identify and generally difficult to reach the ideal standard. The most commonly used method in the prior art is the drum granulation method. The drum granulation method is to crush the raw materials required for the production of compound fertilizers, first enter the disc granulation, then enter the drum to heat and dry to shape, and then enter the screening and packaging. The surface of the compound fertilizer particles produced by this method is rough, and the equipment occupies a large area. Generally, the drum is 20-30 meters long, and the in...

AI Technical Summary

Problems solved by technology

The surface of the compound fertilizer particles produced by this method is rough, and the equipment occupies a large area. Generally, the drum is 20-30 meters long, and the investment is large. Especially the crushing workshop is not only noisy, but also dust flying in the workshop, with unpleasant smell and serious pollution. Working in this environment for a long time will cause serious damage to the body; the nitrogen content of the compound fertilizer produced by this process is low, and when the amount of urea added reaches a certain amount, the process cannot make the produced particles into shape
