[0001] The invention relates to the technical field of fertilizer processing, and in particular to a fertilizer crushing processing device and process. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. In the fertilizer production process, raw materials or semi-finished products often need to be crushed to adjust their particle size and promote the uniform distribution and release of fertilizer nutrients.

[0003] Traditional fertilizer crushing equipment is mostly conventional roller crushers, which crush fertilizers through a set of intermeshing crushing rollers. However, this crushing method is difficult to ensure that all fertilizers are crushed into appropriate particle sizes. At the same time, in the process of crushing fertilizers, when the fertilizers are relatively dry, a large amount of fertilizer dust will be dispersed in the air, causing pollution to the surrounding air, which is inconvenient to use. Summary of the invention

[0010] Furthermore, the screening mechanism includes a limit plate, one side of which is fixedly connected to the inner wall of the shell, a slide rail is fixedly connected to the surface of the limit plate, a sieve plate is meshed with the surface of the slide rail, and a fixing plate is fixedly connected to the bottom of the sieve plate.

[0011] Furthermore, the bottom of the fixing plate is rotatably connected to a support rod, one end of the support rod is rotatably connected to an eccentric wheel, the bottom of the eccentric wheel is fixedly connected to a second motor, and the bottom of the second motor is fixedly connected to the bottom of the inner cavity of the shell through a fixing block.

[0012] Furthermore, the dust removal mechanism comprises a dust suction port, one side of the dust suction port is connected to a dust removal chamber via a pipeline, and a filter plate is provided on the inner wall of the dust removal chamber.

Under the action of the first motor 21, the two primary crushing rollers in the primary crushing roller group 22 are synchronously rotated in the opposite direction to perform primary crushing on the bulk fertilizer. After the primary crushing, the fertilizer enters between the secondary crushing roller group 26 under the action of the guide plate 13. Under the action of the first synchronous wheel 23 driving the second synchronous wheel 25 through the synchronous belt 24, the two secondary crushing rollers in the secondary crushing roller group 26 are synchronously rotated in the opposite direction to perform secondary crushing on the fertilizer.

The fertilizer is screened by the reciprocating motion, and the small-particle fertilizer that meets the requirements is discharged from the discharge port 14 through the sieve plate 33. The large-particle waste enters the circulation pipe 42 under the action of the guide groove 41, and the spiral blade 45 is driven by the third motor 44 to rotate, so that the large-particle fertilizer is discharged from the circulation port 43 along the circulation pipe 42, so that it returns to the feed port 12 and is crushed again until it can pass through the sieve plate 33. During the crushing process, the fan 54 continuously extracts air from the dust suction port 51 in the shell 11. The extracted air is removed from the internal dust through the multi-layer filter plate 53 and is discharged along the air outlet 55, so that the shell 11 is always in a negative pressure environment, avoiding the dust generated by the crushing from escaping to the outside of the shell 11, making it more convenient to use.
