Abstract

The invention discloses an anti-blocking and sorting machine for compound fertilizer production, and mainly relates to the field of fertilizer production. It includes a machine base, a screening mechanism, and a blockage removal mechanism; the screening mechanism, the feeding mechanism, and the blockage removal mechanism are all installed on the machine base; the screening mechanism includes a drum, and the drum is a frustum-shaped cylinder with a linearly increasing inner diameter, and From its narrow end to its wide end, the drum includes the first sieve cylinder, the second sieve cylinder and the buffer cylinder which are connected successively at the first place, and a dust-proof cylinder is set on the circumference of the drum, and the bottom of the dust-proof cylinder is connected with negative pressure. Air source; the blockage removal mechanism includes a flexible block arranged on one side of the peripheral surface of the second screen drum, and the side of the flexible block adjacent to the drum is provided with an action surface, and the air hole connected to the gas joint is provided on the action surface. The air holes are used to spray high-pressure gas onto the second screen drum. The beneficial effect of the invention is that it can realize large-scale continuous screening operation, increase production and reduce costs, and ensure particle size parameters.

Description

technical field

[0001] The invention relates to the field of fertilizer production, in particular to an anti-blocking and screening machine for compound fertilizer production. Background technique

[0002] Most solid fertilizers need to be processed into granules. Fertilizer granulation is an important process in the fertilizer production process. The size and quality of granulation are related to the application effect of fertilizer. For the quality control of fertilizer granulation, its particle size distribution, strength, and uniformity are all important parameters. These parameters, like the content of fertilizer, become important contents of fertilizer quality standards.

[0003] In use, the granular material is mainly mixed with the soil, or buried under the soil, and gradually releases the fertilizer effect. This requires higher requirements on the particle size of the granules. An appropriate particle size can not only ensure the expected dissolution and slow-rele...
