Compound fertilizer particle cooling and screening equipment

Abstract

The invention discloses a compound fertilizer particle cooling and screening equipment. The equipment comprises a cooler, a buffer hopper, a screening device and a rack, wherein the cooler is positioned at the upper end of the rack, the buffer hopper is arranged at the lower end of the cooler, an outlet of the buffer hopper is connected with an inlet of the screening device, two sides of the screening device are fixedly connected with the rack through springs, a cooler feeding hole is formed in the top of the cooler, a cooler air outlet is formed in the upper part of the side face of the cooler, a turnover plate is arranged at the lower part of the cooler, a cylinder and a swing arm are arranged above one side of the turnover plate, and the cylinder is connected with the turnover plate through the swing arm. According to the equipment, the cooling and screening effects are good, the cost is low, the cooling and screening can be completed at the same time, the process arrangement is facilitated, the occupied area is small, fertilizer particles can be bounced by a screen to a certain height under the action of a vibration pump, so that the fertilizer particles are relatively dispersed rather than formed into a stock pile, the cooling effect is good, mechanical stirring is not needed in a cooling and screening process, and the breakage rate of the fertilizer particles can be reduced.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer production, in particular to a cooling and screening device for compound fertilizer particles. Background technique [0002] After the compound fertilizer granules are dried by the dryer, the temperature is usually high, and some granules may disintegrate due to the granulation process. The traditional cooling and screening equipment is usually a drum-type cooling and screening equipment, and its structure is complex. , and it is troublesome to turn over the material. Moreover, it is easy to crush the particles due to mechanical action during the turning process, thereby increasing the rework rate of fertilizer granulation. Secondly, the turning effect of the traditional drum-type cooling and screening equipment is still poor when turning the material. Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, low cost compound fertiliz...
