AI Technical Summary

Technical Problem

Existing slow-release fertilizer production equipment made from medicinal herbs is prone to wear and pulverization under long-term chemical erosion from contact with medicinal herb powder and excipients, resulting in impurities falling off the inner wall and contaminating the product. Furthermore, the unreasonable design of the gaps between the internal components of the equipment makes it easy for them to clump and become stuck, causing production blockages and low efficiency.

Method used

The inner walls of the material preparation and storage cylinders are coated with a polytetrafluoroethylene (PTFE) anti-powdering coating. Combined with a servo motor-driven rotating shaft and extrusion rollers, the material is prevented from clumping through directional extrusion molding and rubber ring ejection design. At the same time, an anti-clogging mechanism is equipped to automatically handle clogging problems.

Benefits of technology

It significantly reduced the incidence of blockage failures, improved the continuity and stability of production, reduced the frequency of maintenance, ensured product purity and production efficiency, and extended the service life of the equipment.

Abstract

The application relates to a medicine material granulation technical field, in particular to a high-efficiency granulation device for medicine material slow-release fertilizer production and a use method thereof, which comprises a mounting base, the upper end of the mounting base is fixedly connected with a mounting barrel through a connecting rod, the bottom of the mounting barrel is fixedly connected with a material-making barrel, the upper end of the mounting base is also fixedly connected with a storage barrel for storing processed materials, a jam-preventing mechanism is also fixedly installed between the mounting barrel and the material-making barrel, a servo motor is used for accurately driving a rotating shaft and an extrusion roller to step by step rotate, accumulated materials are directionally extruded and formed, meanwhile, a linkage extrusion column and a rubber ring cooperate with a conical column to push out the materials in a forming hole, the synergistic design of double extrusion and accurate pushing out can effectively avoid material caking and plugging in the forming hole, greatly reduces the plugging failure rate, reduces the frequency of manual shutdown and cleaning, significantly improves the continuity and stability of the granulation process, and further improves the overall production efficiency.
