Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a screening and dust removal device for blended fertilizer production. Background Technology

[0002] The screening device for blended fertilizer production is used to classify and screen various granular raw fertilizer materials by particle size. Its core function is to remove excessively large or small particles through physical screening to ensure the uniformity of particle size in the final product. The device is usually composed of structures such as vibrating screen, drum screen or air classifier, and is equipped with feeding, conveying and collecting systems to achieve automated continuous operation. The uniformly sized fertilizer particles after screening can improve the uniformity of fertilization and avoid uneven nutrient distribution caused by excessively large or small particles, thereby improving fertilizer efficiency.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Screening Cylinder Structure for Fertilizer Screening Equipment," and the patent application number is 201720567024.4. This utility model discloses a screening cylinder structure for fertilizer screening equipment, including a first positioning plate, a second positioning plate, and a first screen and a second screen arranged in a cylindrical shape. The first screen is located inside the second screen. One end of the first screen has a first positioning ring, and the other end has a second positioning ring. One end of the second screen has a third positioning ring, and the other end has a fourth positioning ring. The first positioning plate has a first annular groove that mates with the first positioning ring, and a second annular groove that mates with the third positioning ring. Both the second and fourth positioning rings have annular protrusions. The second positioning plate has an annular groove that mates with the annular protrusions. A screw is welded to the first positioning plate and extends through to one side of the second positioning plate. A nut is threaded onto the screw.
