Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fertilizer screening, in particular to a screening device for granular powder. BACKGROUND

[0002] Fertilizer is used for agricultural planting, improves soil fertility, provides nutrients for crops and promotes the growth of crops. In order to facilitate the uniform distribution of fertilizer in farmland, it is made into granular form during fertilizer production, so that agricultural workers can throw and scatter the fertilizer.

[0003] During fertilizer production, various equipment such as crushing and mixing equipment, reaction equipment, granulation equipment, drying equipment, screening equipment, coating equipment and packaging equipment are needed to produce granular fertilizer from various raw materials. As can be seen from the above, after the granulation equipment produces fertilizer particles, the fertilizer particles are dried in the drying equipment, and after screening treatment, the coating treatment can be carried out, and the packaging and sales of the fertilizer particles are completed.

[0004] At present, there are many devices for screening particles, such as a kind of drum type fertilizer particle fine selection grading machine disclosed in a Chinese patent with publication number CN113634479B, which comprises a base, supporting legs, a reciprocating mechanism, an angle adjusting mechanism, a cylinder screen mechanism and a hole cleaning mechanism. The base is provided with supporting legs on the front and rear sides of the lower end, and the reciprocating mechanism is installed on the upper end of the base. The angle adjusting mechanism is provided on the upper end of the reciprocating mechanism, and the cylinder screen mechanism is installed on the upper end of the angle adjusting mechanism. The hole cleaning mechanism is provided on the upper end of the cylinder screen mechanism. When the screening device provided by the above patent screens powder, the fertilizer enters from the top of the drum screen. Because a plurality of screening holes are provided on the drum screen, and the hole diameter of the screening holes gradually increases from top to bottom, particles of different diameters will be output from screening holes of different diameters, and fall into the material collecting bin from the material leakage hopper, thereby completing the screening treatment of the fertilizer particles.

[0005] Although the above patent provides screening that can realize the screening of particles and can independently store different particles, it still has some defects, such as breakage caused by impact during particle rolling, thereby forming fertilizer powder. The particle size of the powder is small, so the powder will pass through the screening hole and fall into the fertilizer bin of different particle sizes. When the fertilizer is coated, the powder is processed and packaged simultaneously with the fertilizer, causing quality problems and affecting the reputation of the manufacturer.
