The invention discloses organic fertilizer preparation equipment which comprises an organic fertilizer conveying outer cylinder fixedly arranged transversely. A wet fertilizer feeding pipe is connected to the upper portion of the left side of the organic fertilizer conveying outer cylinder. A dry fertilizer discharging pipe is connected to the lower portion of the right side of the organic fertilizer conveying outer cylinder. A valve is arranged on the dry fertilizer discharging pipe. According to the equipment, waste gas of a boiler does not make direct contact with organic fertilizer, conveying blades are utilized for indirectly heating the organic fertilizer, dehydrating is promoted, and therefore harmful gas in the waste gas of the boiler does not pollute the organic fertilizer. When flowing through an air heating channel continuously in a spiral shape, the air is heated by packing auger conveying heat exchange blades between a hollow rotating shaft and an air guide pipe, so that the air guided out to the right end of the organic fertilizer conveying channel through a plurality of air guide-out holes is the heated air, and the heated air effectively prevents vapor in the organic fertilizer conveying channel from being condensed.
Description
technical field [0001] The invention belongs to the field of organic fertilizer preparation. Background technique [0002] In the existing dehydration of organic fertilizers, high-temperature boiler exhaust gas is continuously introduced into the dehydration drum, and the hot exhaust gas of the exhaust gas is used to bake the wet organic fertilizer in the drum, thereby achieving the purpose of dehydration, but the boiler exhaust gas often contains sulfur dioxide, etc. Harmful gases can contaminate 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 a kind of organic fertilizer preparation equipment and its preparation process which avoid waste gas pollution. [0004] Technical solution: In order to achieve the above object, a kind of organic fertilizer preparation equipment of the present invention includes an organic fertilizer transmission outer cylinder ...
