Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to a screening device for organic fertilizer granule production. Background Technique

[0002] Organic fertilizer is a kind of fertilizer made from organic substances, mainly derived from plant and animal residues, excreta, etc. It contains a large number of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and trace elements such as potassium, calcium, magnesium, iron, copper, zinc, manganese, etc., and can provide comprehensive and lasting nutrition for plants. Organic fertilizer granules are granular organic fertilizers made by mixing organic substances and fertilizers. Compared with traditional organic fertilizers, organic fertilizer granules have a compact structure, can be stored for a long time, and are more convenient for fertilization, making organic fertilizers widely used in agricultural production. During the production process of organic fertilizer granules, it is necessary to screen the organic fertilizer raw materials. Since the sources of organic fertilizer raw materials are extensive, the raw materials are often doped with sundries such as stones, straws, weeds, plastics, and iron metals during the collection and processing. Therefore, it is necessary to screen the organic fertilizer raw materials during the production process of organic fertilizer granules.

[0003] Traditional screening methods often use simple sieves for screening, but this method has problems such as low efficiency and low screening accuracy, and it is particularly inconvenient to clean the iron impurities in the organic fertilizer raw materials. Iron impurities are relatively common in organic fertilizer raw materials, and they may come from farm tools, mechanical equipment, etc. These iron impurities will not only affect the purity of organic fertilizer granules, but may also cause wear and damage to production equipment, shortening the service life of the equipment. Therefore, we need to propose a screening device for organic fertilizer granule production. Content of the Utility Model
