Description

Technical Field

[0001] The utility model belongs to the technical field of controlled-release fertilizer coating, and specifically relates to a continuous coating fluidized bed for controlled-release fertilizers. Background Technique

[0002] Controlled-release fertilizers are an advanced form of slow-release fertilizers, mainly controlling the release of nutrients through coating technology to achieve the purposes of safety, long-term effectiveness, high efficiency, etc. They are the main direction of modern fertilizer development and are suitable for mechanized production, especially to meet the need of simultaneous sowing of seeds and fertilizers.

[0003] When coating controlled-release fertilizers, a fluidized bed is used. When the existing fluidized bed is in use, the materials are first put into the raw material container, and then the raw material container is placed on the main machine. After fluidization, the raw material container is unloaded, and then the fertilizer is poured out. When replacing the new fertilizer, this process requires the fluidized bed to stop for a long time, which is not conducive to continuous operation and has poor efficiency.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet.

[0005] Therefore, in order to solve the above problems, the utility model provides a continuous coating fluidized bed for controlled-release fertilizers. Content of the Utility Model

The raw materials are pre-put into the raw material container, and then the raw material container is moved between the heating base and the granulation chamber. The air is processed by the air induction component and the air treatment component, and then transported into the heating base. After the heating base heats and processes the air, it is transported into the raw material container, and then the raw material container is agitated and boiled into a fluidized state. During this process, the raw materials are coated and dried. After the treatment is completed, the position of the raw material container is converted by the position adjustment mechanism, so that the processed raw material container can be removed, and the next group of raw material containers is moved between the heating base and the granulation chamber to continue the coating and drying operation. This method has high efficiency and strong practicability.
