Device for spraying curing agent on surfaces of fertilizer core particles for zinc fertilizer preparation

Abstract

The invention belongs to the technical field of zinc fertilizer production equipment, and particularly relates to a device for spraying a curing agent on surfaces of fertilizer core particles for zincfertilizer preparation. The device comprises a device body, wherein a rotary drum is arranged in the device body, a spiral blade is fixedly connected to the inner wall of the rotary drum, a feeding pipe is fixedly connected to the left end of a mounting ring located on the left side, the left end of the feeding pipe penetrates through the device body and extends to the left of the device body, the outer wall of the feeding pipe is movably sleeved with a transmission belt, the lower end of the inner wall of the transmission belt sleeves a first motor, the right side of the device body is fixedly connected with a conical pipe, a mounting pipe is arranged in the rotary drum, spray heads are fixedly mounted on the upper side and the lower side of the mounting pipe correspondingly, zinc fertilizer solid particles are poured into the feeding pipe, the first motor is started to drive the rotary drum and the spiral blade to rotate, the zinc fertilizer particles are evenly separated by the spiral blade and move rightwards, and the curing agent is injected into the left end of the mounting pipe and atomized and sprayed to the inner wall of the rotary drum through the plurality of spray heads, so that the curing agent is evenly sprayed to the surfaces of the particles.

Description

Technical field[0001]The invention relates to the technical field of zinc fertilizer production equipment, in particular to a device for spraying curing agent on the surface of fertilizer core particles for preparing zinc fertilizer.Background technique[0002]Plant growth and development are stagnant due to zinc deficiency, leaves shrinking, and stem nodes shortened. There are many zinc-deficient soils in China. Zinc fertilizer can be applied as a base, topdressing, seed soaking, seed dressing, and spraying. In agricultural production, in order to maximize the fertilizer effect, a layer of film is often applied to the surface of the fertilizer particles. People often say The coated fertilizer is sprayed with curing agent on the surface of the fertilizer. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after being applied to the soil to extend the fertilizer efficiency; the production of coated fertilizers usually requires fertilizer...

AI Technical Summary

Problems solved by technology

[0003] When the current fertilizer coating machine is working, the fertilizer particles are piled up in the same place, and the surface of the particles cannot be evenly coated. The fertilizer particles and the curing agent are directly in contact with the inner wall of the drum, which causes the inner wall of the drum to be easily rusted. After the drum is rusted, it needs to Timely rust removal is not convenient for the staff to clean up, and at the same time, the normal use of the drum may be affected when the rust is severe
