Description

Technical Field

[0001] The utility model belongs to the technical field of water-soluble fertilizer production, and particularly relates to a raw material crushing device for water-soluble fertilizer production. Background Art

[0002] Water-soluble fertilizers usually contain a variety of macroelements, trace elements and possible additives. The uniform particle size of each component is conducive to uniform mixing. The crushing device ensures that the raw materials reach similar particle sizes, reducing stratification or aggregation caused by particle size differences during mixing, thereby improving the uniformity and stability of the final product. In the prior art, the raw materials are usually crushed by arranging extrusion rollers inside the working box, and a dust suction box and suction holes are provided on one side of the working box to absorb dust. However, in this method, the suction angle of the suction hole is fixed and cannot be rotated to adjust the suction angle. When different types of raw materials are crushed, the location and diffusion range of dust generation may be different. The suction holes with fixed angles may not be able to flexibly adapt to these changes, resulting in poor dust collection effect.

[0003] For example, the utility model with announcement number CN213528835U discloses a raw material crushing device for the production of trace element water-soluble fertilizer. In the technical solution of this patent, the raw material is crushed by two extrusion rollers connected and symmetrically rotating inside the working box, and a vacuum cleaner and suction holes are provided on the other side of the working box to absorb the dust generated during the crushing process. However, in this method, the suction angle of the suction hole is fixed and cannot be rotated to adjust the suction angle. It may not be possible to cover all dust generating points in the crushing area. In particular, under different working conditions of the crushing equipment, the dust drift direction may change, and the suction holes with fixed angles may not be able to efficiently absorb dust.
