A compound fertilizer cooling and screening equipment

Abstract

The invention relates to the field of chemical fertilizer manufacturing, in particular to cooling and screening equipment of compound fertilizer. The cooling and screening equipment of the compound fertilizer aims at achieving the technical purposes that the cooling effect of the compound fertilizer is good, the cold air utilization rate is high, the cooled compound fertilizer is easily taken outcompletely, and the productivity of the compound fertilizer is high. In order to achieve the technical purposes, the cooling and screening equipment of the compound fertilizer comprises a screening box, a cooling barrel, a first electromagnet, a second electromagnet, an air inflow pipe, an air outflow pipe, a mounting plate, a rotating mechanism, a first box door, a second box door, a guide plate,a first connecting rod, a net plate, a collecting frame, a lifting mechanism, a hydraulic cylinder, a base, fishing plates, magnet blocks, third elastic parts, third connecting rods, arc-shaped plates and spiculated bodies. The base is fixedly connected to the ground. The effects that the cooling effect of the compound fertilizer is good, the cold air utilization rate is high, the cooled compoundfertilizer is easily taken out completely, and the productivity of the compound fertilizer is high are achieved.

Description

technical field [0001] The invention relates to the field of chemical fertilizer manufacturing, in particular to a compound fertilizer cooling and screening equipment. Background technique [0002] Fertilizer is an indispensable and important agricultural material for high and stable crop yields. The production and use of chemical fertilizers play an important role in increasing crop yields and ensuring national food production and security. Due to the inconvenient use of elemental nitrogen, phosphorus and potassium fertilizers, compound fertilizers have become popular among farmers in current agricultural production, especially organic and inorganic compound fertilizers are more conducive to high crop yields and soil fertility. [0003] In the compound fertilizer production process, cooling is one of the important steps in the production process. In the prior art, most of the cooling devices are used to roll the compound fertilizer and cool it by blowing cold air. This met...
