High-efficiency preparation system of organic fertilizer and its preparation method for preparing organic fertilizer

Abstract

The invention discloses an efficient preparation system of organic fertilizer and a preparation process method for preparing the organic fertilizer. The efficient preparation system of the organic fertilizer comprises an organic fertilizer mixing device, a dehydration barrel, a dehydration combustion heat source and an organic fertilizer cooling device. The discharging end of the organic fertilizer mixing device is correspondingly arranged above a feeding funnel. The feeding hopper is correspondingly arranged on a feeding pipe at the left end of the dehydration barrel. A discharging pipe at the right end of the dehydration barrel is correspondingly connected with the feeding end of the organic fertilizer cooling device. The efficient preparation system is simple in structure, hot air is indirect contact with the organic fertilizer and takes away moisture, high-temperature smoke indirectly heats the organic fertilizer through a spiral hollow conveying blade and is not in direct contactwith the organic fertilizer; and it is effectively avoided that moister in the smoke encounters the organic fertilizer low in temperature to generate a condensation phenomenon, and consequently the dehydration efficiency on the organic fertilizer is reduced.

Description

technical field [0001] The invention belongs to the field of organic fertilizer preparation. Background technique [0002] The dehydration of organic fertilizers often introduces the flue gas generated by the combustion furnace continuously into the dehydration drum, and uses the hot exhaust gas of the flue gas to bake the wet organic fertilizer in the drum, thereby achieving the purpose of dehydration, but the product of the flue gas itself contains moisture , and the flue gas often contains harmful gases such as sulfur dioxide, which will pollute organic fertilizers. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an efficient preparation system for organic fertilizer and a preparation process for preparing organic fertilizer. [0004] Technical solution: In order to achieve the above object, the high-efficiency preparation system of organic fertilizer of the present inve...
