Rotary drum granulator for organic fertilizer production

Abstract

The invention relates to the technical field of organic fertilizer manufacturing, and discloses a rotary drum granulator for organic fertilizer production, the rotary drum granulator comprises a cylinder, the inner wall of the cylinder is fixedly connected with four spraying devices, the spraying devices are uniformly arranged around the cylinder, the inner wall of the cylinder between two spraying devices is fixedly connected with a supporting piece, and the supporting piece is fixedly connected with the inner wall of the cylinder. A lining film is clamped to the side surface of the spraying device located on the outer side of the supporting piece, a movable cavity is formed in the supporting piece, a vertical hole is formed in the supporting piece located at the bottom end of the movable cavity, and the supporting piece is movably connected with the movable piece in a sleeving mode through the vertical hole. The supporting piece is arranged between the cylinder body and the lining film, and the movable piece is movably sleeved with the supporting piece, so that the movable piece pushes the lining film to change the shape under the action of the gravity of the movable piece and the elastic force of the spring, materials attached to the surface of the lining film can fall off in time, the lining film is cleaned, the granulation environment in the cylinder body is protected, and the granulation efficiency is improved. And the granulation quality is improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a drum granulator for organic fertilizer production. Background technique [0002] Drum granulator, also known as drum granulator, is a kind of machine for making materials into shapes. It is suitable for large-scale organic fertilizer granulation production. A certain amount of water or steam is added to make the powder material fully chemically react after the humidity is adjusted in the cylinder, and under certain liquid phase conditions, the rotary motion of the cylinder is used to promote the extrusion force between the material particles to agglomerate into balls. [0003] However, in actual use, due to the high viscosity of some materials due to the steam, they are easy to stick to the surface of the inner lining film of the drum when rolling in the drum. In addition, because the material often accumulates at the bottom of the cylinder and does not d...

Problems solved by technology

[0003] However, in actual use, due to the high viscosity of some materials due to the steam, they are easy to stick to the surface of the inner lining film of the drum when rolling in the drum. In addition, because the material often accumulates at the bottom of the cylinder and does not disperse, the steam ejected from the spray pipe cannot be perfectly combined with the material, resulting in uneven humidity of the material, which affects the pelletization of the granulator.
