Material attachment prevention pelletizer for fertilizer production

Abstract

The invention relates to fertilizer production equipment, in particular to a material attachment prevention pelletizer for fertilizer production.The material attachment prevention pelletizer comprises a roller, rail rings fixedly mounted on the outer wall of the roller and a tooth ring, the tooth ring is in transmission connection with a drive motor through a drive gear, the rail rings are mounted on a rail, the two ends of the roller are provided with a feeding device and a discharging opening respectively, the inner wall of the roller is provided with an inner lining cylinder, the inner lining cylinder is of a cylindrical structure made of flexible materials and coaxially arranged with the roller, a plurality of supporting strips are evenly distributed along the inner circumference of the inner lining cylinder and fixedly connected to the inner lining cylinder through bolts, and the outside of the roller is provided with an electromagnetic shaker causing vibration of the supporting strips.According to the material attachment prevention pelletizer, the inner lining cylinder generates high-frequency vibration through the external shaker, material attachment substances can be cleared, the material attachment prevention pelletizer is reasonable in structure, high in production efficiency and free of machine halt and sorting, excessive abrasion of the inner lining cylinder can be avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to an anti-caking granulator for chemical fertilizer production. Background technique [0002] In the production process of compound fertilizer, in the drying process, it is necessary to roll the powdery raw materials into granules through the drum granulator. Most of the granulators in this step adopt a drum structure. The powder raw materials are placed in the drum, and the slurry or steam or water is sprayed into the drum through the spray pipe to increase the liquid phase of the granulated material to make the drum agglomerate into granules. The outer wall of these drum granulators is provided with a plurality of circular tracks, at least one of which is a gear rail, which drives the drum to rotate through gear engagement, and at least two other rails are supported on supporting wheels with grooves to keep the drum in balance . In actual use, the viscosity of the g...

Problems solved by technology

However, no matter whether the lining tube is stuck or not, the wall of the lining tube is always stretched and deformed during the working process, and the deformation range of the lining tube is large and the frequency is slow, resulting in a fast wear of the lining tube; at the same time, if it is equipped with If the weight of the heavy iron is light, the use effect will not be good. If the weight of the counterweight iron is large, it will easily increase the wear of the inner liner
