Wet particle sorting machine

Abstract

The invention discloses a wet particle sorting machine. The wet particle sorting machine comprises a rack, and a screening mechanism is arranged on the rack; a material receiving mechanism is arrangedon the lower portion of the screening mechanism and connected with the rack, and a self-rotation power mechanism or a friction driving mechanism is arranged between the screening mechanism and the material receiving mechanism; and the self-rotation power mechanism or the friction driving mechanism is in contact with the screening mechanism; the screening mechanism comprises a plurality of conveying rollers arranged side by side, the two axial ends of each conveying roller are rotationally connected with the rack, and a screening gap is formed between every two adjacent conveying rollers. Through the design that the self-rotation power mechanism is arranged between the screening mechanism and the material receiving mechanism, the self-rotation power mechanism can drive the conveying rollers to rotate, so that materials poured on the conveying rollers are sorted and conveyed to one end of the screening mechanism, sorting operation of material particles is completed, operation is easy, convenient and fast, and convenience is brought to the screening work of the organic fertilizer particles.

Description

technical field [0001] The invention relates to the field of organic fertilizer production, in particular to a wet particle sorter. Background technique [0002] Organic fertilizer can improve soil, improve soil fertility, restore soil to normal ecological balance, increase soil organic matter content, form aggregate structure, improve soil air permeability, water retention, and fertilizer retention performance, which is conducive to the growth of crop root systems and improves plant quality. and yield. It can effectively improve the utilization rate of chemical fertilizers, decompose pesticide residues, and improve crop quality. Organic fertilizers can reduce the harm of agricultural products to humans and animals caused by excessive application of chemical fertilizers; on the other hand, the inorganic and organic nutrients contained in organic fertilizers can directly provide nutrients for crops, which is conducive to the absorption of crops and the improvement of quality...

AI Technical Summary

Problems solved by technology

However, the organic fertilizer particles produced by the current granulation machinery are of different sizes, and those that are too large or too small are unqualified, that is, the organic fertilizer particles that are too large or too small are unqualified, and the pass rate is less than 50%. %, these organic fertilizer particles all enter the next drying process for drying. After drying, the unqualified particles are screened out. The unqualified particles are crushed and then returned to the granulator for re-adding water to granulate. The waste of energy is serious. ; If the unqualified particles can be sorted out before drying and returned to continue to granulate, the particles entering the dryer are all qualified particles, which will greatly save fuel and reduce drying, cooling, etc. equipment

Over the years, industry experts have made many attempts to choose vibrating sieve or cylindrical sieve, because the production of organic fertilizer granules needs to add water and clay to granulate by agglomeration method, the size of the organic fertilizer granules just out of the granulator is inconsistent, and The moisture content is between 30% and 40%, the particles are soft and sticky, fragile, and easy to stick to the screen. It is not feasible to screen out the unqualified particles before entering the dryer with the screening equipment in the prior art.
