Problems solved by technology
Its advantage is that two kinds of anti-caking agents, liquid and solid, can be wrapped at the same time in the wrapping kiln, and the wrapping treatment efficiency is higher. The disadvantage is that the two kinds of anti-caking agents cannot be evenly wrapped on the particle surface, resulting in anti-caking of the product. block effect is not good

Abstract
The invention discloses a wrapping kiln for anti-blocking agents for compound fertilizer. A spraying device for spraying a liquid anti-blocking agent into the kiln is arranged at a kiln head, and a powder feeding device for spraying a powdery anti-blocking agent into the kiln is arranged at a kiln tail; an annular partition board is arranged on the inner wall of the middle of a kiln body and divides an inner cavity of the kiln body into a front section and a rear section, the front section is a liquid agent wrapping area, the rear section is a powdery agent wrapping area, and the height of the annular partition board in the radial direction of the kiln body is larger than that of a kiln tail outlet baffle board in the radial direction of the kiln body; multiple axially distributed lifting boards are arranged on the kiln body inner walls in the liquid agent wrapping area and the powdery agent wrapping area respectively, and side walls, used for lifting materials, of each lifting board in the powdery agent wrapping area are inclined to a connecting line of the top of the lifting board and the kiln body symcenter. According to the subsection arrangement of the inner cavity of the kiln body, adsorption of the liquid anti-blocking agent and adsorption of the powdery anti-blocking agent are facilitated, and the wrapping effect can be improved.
Description
technical field [0001] The invention relates to a device for covering the surface of compound fertilizer particles with an anti-caking agent, in particular to a compound fertilizer anti-caking agent coating kiln. Background technique [0002] Compound fertilizers will agglomerate during transportation and use, which brings inconvenience to users. In order to prevent compound fertilizers from agglomerating, anti-caking agents are usually used to treat compound fertilizers in industry. According to the application method, anti-caking agents are divided into internal anti-caking agents and external anti-caking agents. Internal anti-caking agents are added during fertilizer production to increase fertilizer hardness or change crystal morphology. The external anti-caking agent is mainly to wrap the anti-caking agent on the surface of fertilizer granules with wrapping equipment to form a protective film to prevent the fertilizer granules from absorbing moisture. The external an...
