Description

Organic fertilizer screening device

Technical Field

The utility model relates to the technical field of fertilizer processing devices, in particular to an organic fertilizer screening device.

Background Art

Organic fertilizer refers to fertilizer made from animal excrement or animal and plant residues and other organic-rich byproduct resources as the main raw materials, which are fermented and decomposed. After the raw materials are mixed, fermented, aged and crushed, the organic fertilizer needs to be screened. The screened organic fertilizer can be directly packaged into powdered organic fertilizer or enter the next process for granulation. During the screening, there are large particles of fertilizer particles that cannot pass the screening and need to be crushed again, which is cumbersome.

Chinese patent publication number CN212524845U discloses an organic fertilizer screening device, which screens the fertilizer by conveying the fertilizer into a screen drum, and the fertilizer is turned over by turning blades in the screen drum to speed up the screening efficiency. The screen drum is inclined and has a guide plate at the bottom to facilitate the discharge of material residue and fertilizer. The rotating shaft is a hollow tube structure and high-pressure gas is conveyed by a high-pressure air pump, so that the rotating shaft cleans the screen through high-pressure air during rotation. When there is residual material residue in the screen drum, the large fertilizer particles can collide with the screen drum and be broken by the rotation of the turning blades and the impact of the high-pressure gas, thereby increasing the screening output of the fertilizer.

However, the above patent has the following shortcomings:

The screening device only allows large-particle fertilizer particles to collide with the screen drum under the impact of high-pressure gas and be broken, which has a poor effect of breaking the fertilizer particles, reduces the screening output, and the large-particle fertilizer particles still need to be processed after screening.
