Efficient and environment-friendly compound fertilizer granulating and drying device

Abstract

The invention discloses an efficient and environment-friendly compound fertilizer granulating and drying device, and relates to the technical field of chemical fertilizer manufacturing. The efficientand environment-friendly compound fertilizer granulating and drying device comprises an extrusion box, a granulation box cover is arranged at the top end of the extrusion box; a first circular throughhole is formed in the center of the granulation box cover; a spiral rod is arranged in the first circular through hole in a penetrating mode and extends into the extrusion box, a motor is arranged atthe top end of the spiral rod, an output shaft of the motor is connected with the spiral rod, an extrusion plate is arranged on the surface of the spiral rod, and a feeding pipe is arranged at the bottom end of the surface of the extrusion box. The efficient and environment-friendly compound fertilizer granulating and drying device has the beneficial effects that the granulation rate of a chemical fertilizer is improved; a drying device is arranged at the bottom end of a third funnel to dry the chemical fertilizer; the water content of the fertilizer is reduced, the loosening degree of the chemical fertilizer is improved, the chemical fertilizer is not prone to caking, spreading of the chemical fertilizer is facilitated, a first brush and a second brush are arranged on the outer sides ofa first roller and a second roller to peel off the fertilizer adhering to the surfaces of the first roller and the second roller, and the surfaces of the first roller and the second roller are cleaner.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizer manufacturing, in particular to an efficient and environment-friendly compound fertilizer granulation and drying device. Background technique [0002] Modern agriculture is intensive farming, which requires the application of various compound fertilizers. Fertilizer production technology has undergone great changes in recent years. Low-nutrient products have become less and less popular, while high-concentration, compound nutrient fertilizers have become the mainstream of the market. In the past, high-concentration nutrient fertilizers were all in the form of fine powders, and the raw materials would be stratified or agglomerated during storage and transportation; in addition, when powdered fertilizers were applied, a considerable amount of fertilizers would be blown away by the wind or blown away from the plants by rain. The roots are washed away, and the fertilizer effect is release...

Problems solved by technology

[0003] For example, the energy-saving granulator for organic fertilizer production with application number CN201821757354.0 includes a squeeze box, one end of the squeeze box is provided with a feed port, and a screw is arranged inside the squeeze box, and the two ends of the screw extend out of the squeeze box , one end of the extrusion box is fixed with a motor that drives the screw, and the other end of the extrusion box is evenly distributed with a number of granulation holes, and a cutter connected to the screw is provided on the outside of the granulation hole, because the granulator only uses the cutter to squeeze out the pellets. The fertilizer is cut, and there is no device that can turn the fertilizer into round granules, so the produced fertilizer cannot meet the fertilizer granulation rate stipulated by the state. This phenomenon will cause the fertilizer to release too quickly; and because the device is not installed Due to the drying device, the moisture content of the fertilizer is relatively high, which is easy to cause the agglomeration of the fertilizer, and it is not convenient to spread the fertilizer
