Description

Horizontal rotary granulator Technical Field The utility model relates to the field of granulators, in particular to a horizontal rotary granulator. Background The horizontal rotary granulator is a kind of granule preparation equipment commonly used in the industries of pharmacy, food, chemical industry and the like, and is mainly used for preparing powdery raw materials into uniform granules through processes of rotation, extrusion, cutting and the like. At present, a plurality of key technical defects exist in the operation process of the horizontal rotary granulator, and the stability and the service life of equipment are seriously influenced. Firstly, the power shaft connected with the blanking device is unreasonable in design, the shaft diameter is too small, and meanwhile, a small bearing is adopted for supporting, so that the overall structure strength is insufficient. Simultaneously, the bearing is subjected to huge pressure for a long time and lacks effective sealing, so that the materials easily enter the bearing, lubrication failure and abrasion are aggravated, and finally the bearing is frequently damaged. Secondly, the power shaft of the rotary grain pressing knife adopts a bearing supporting structure, the problem of material invasion is also faced, the bearing is rapidly worn in a polluted environment, and the reliability of equipment is further reduced. These problems directly lead to high failure rate of the horizontal rotary granulator, and the horizontal rotary granulator needs frequent shutdown for maintenance, seriously affects the production progress and increases the maintenance cost. In addition, since the core components (such as the bearings and the power shafts) are repeatedly damaged and the performance is difficult to fully recover after maintenance, the whole service life of the equipment is greatly shortened, and the service life of the equipment can be maintained for only half a year to one year after frequent maintenance, and finally, the equipment is scrapped due to failure of the key components.
