Organic fertilizer drying apparatus for agricultural production and drying method

Abstract

The present invention discloses an organic fertilizer drying apparatus for agricultural production and a drying method. The apparatus comprises a drying cylinder; a loading door and an unloading doorare detachably connected to the top and the bottom of the drying cylinder, respectively; a ventilation structure is provided on the outer wall of the drying cylinder; a rotation frame is rotatably connected to the middle position between two end inner walls of the drying cylinder, and one end of the rotation frame is in transmission connection to a drive motor; multiple protruding edge structuresare provided on the outer wall of the rotation frame; and the rotation frame is assembled by multiple net plate structures. The method comprises that as the rotation frame rotates, organic fertilizersflow and roll over in the drying cavity with a guide member; and a gap in the drying cavity is continuously changed by the protruding edge of the rotation frame. In the present invention, the gap inthe drying cavity is continuously changed by the protruding edge of the rotation frame, and some of the organic fertilizers are shaken into the connection cavity for uniform dispersion by means of meshes of the rotation frame, so that the organic fertilizers in the drying cylinder are dispersed and dried.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer drying, in particular to an organic fertilizer drying device and drying method for agricultural production. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. The labor objects of agriculture are living animals and plants, and the products obtained are the animals and plants themselves. In the current agricultural production process, organic fertilizers are often used together. Before the organic fertilizer is processed and used, it is often necessary to dry the fertilizer. [0003] In the prior art, in the process of drying agricultural organic fertilizers, a drum-type drying cylinder is generally used to heat the inside of the drying cylinder or use hot air to circulate, and then make the organic fertilizer rotate along with the inner wall of the drum to perform dry...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, in the process of drying agricultural organic fertilizers, a drum-type drying cylinder is generally used to heat the inside of the drying cylinder or use hot air to circulate, and then make the organic fertilizer rotate along with the inner wall of the drum to perform drying operations, but often The organic fertilizer accumulated in the drum sticks together due to the large humidity, especially the part in the middle of the piled fertilizer, because it always moves as a whole with the rotation of the drum, and the position in the middle is always stuck together, resulting in poor drying effect on the organic fertilizer and The drying efficiency is low. In the prior art, there is a counter-rotating agitator in the drum, but this reverse agitation will cause excessive impact on the organic fertilizer and cause damage to the fertilizer.
