Integrated internal circulation spheroidizing machine

Abstract

The invention belongs to a device in the field of organic fertilizer granulation, in particular to an integrated internal circulation spheroidizing machine. The machine includes an outer cylinder, wherein a rotating shaft is arranged in the middle axis position of the outer cylinder; one end of the rotating shaft penetrates through a bearing and is linked with a motor driving shaft through a conveyor belt; a feeding hole is also formed in the upper cover plate; a discharge hole is formed in the lower part of the outer cylinder; a plurality of layers of spheroidizing discs are fixedly arrangedon the rotating shaft in the outer cylinder at equal intervals; an inner cylinder is arranged on each layer of spheroidizing discs; the inner cylinder is fixedly connected with the outer cylinder through a plurality of connecting pieces; a plurality of discharging openings are formed in the periphery, corresponding to the outer wall of the inner cylinder, of the spheroidizing discs, material blocking rings are fixedly arranged at the positions, corresponding to the discharging openings, of the outer wall of the inner cylinder; a funnel is fixedly arranged on the lower portion, corresponding tothe outer edges of the discharging openings, of the spheroidizing discs. The integrated internal circulation spheroidizing machine is small in occupied area, capable of achieving continuous production and high in roundness of discharged materials.

Description

technical field [0001] The invention belongs to a device in the field of organic fertilizer granulation, and in particular relates to an integrated internal circulation circular throwing machine. Background technique [0002] The rounding machine in the prior art is mainly a single-stage rounding machine, or it is connected in series with multiple rounding machines, and the granular fertilizer is rounded by using the principle of a centrifuge. The fertilizer is put into a rounding machine and passed through With the high-speed rotation of the equipment, the fertilizer is directly sent out or enters the second rounding machine for two-stage rounding, or continuously performs three-stage and four-stage rounding according to production needs. Every time a rounding process is added, a rounding machine needs to be added, and each rounding machine is equipped with a motor, which consumes a lot of energy, and the rounding machine occupies a large area, which is not conducive to pro...

AI Technical Summary

Problems solved by technology

The circular throwing machine adopts the form surrounded by multi-layer cylinders, so that the relative movement speed difference between the material and the chassis, and the material and the cylinder is small, and the throwing efficiency is low; in addition, the discharge door that can be opened and closed is set between the cylinders to realize communication. Continuous production cannot be achieved by opening or closing the discharge door after each layer of rounding; and in this patent, when the material enters the lower level of rounding through the discharge door, the material is easily discharged when it is centrifugally driven by the throwing drum The door is cut into powder, resulting in waste, which affects the pass rate of the product
