Pneumatic anti-clogging cooling device of biomass particle granulator ring mold

Abstract

The invention discloses a pneumatic anti-clogging cooling device of a biomass particle granulator ring mold. The device is characterized by comprising a forced air supply pipe (6) and air supply branch pipes (7), wherein the forced air supply pipe (6) is annular, a plurality of air supply branch pipes (7) communicated with the forced air supply pipe (6) are axially arranged on the forced air supply pipe (6), and the air supply branch pipes (7) are communicated with the interior of a ring mold (8) of a granulator (1). The air is directly and forcibly circulated from the interior of the ring mold to the outside by means of mold holes of the ring mold, and the air cooling effect is direct and thorough, so overheating of the ring mold is radically avoided; and meanwhile, the compressed air can impact the mold holes of the ring mold to play a role in dredging and blow away the powder deposited at the mold holes of the ring mold so as to effectively avoid clogging.

Description

technical field [0001] The invention relates to the field of biomass granulation, in particular to a pneumatic anti-clogging cooling device for a ring die of a biomass granulator. Background technique [0002] Biomass pellets are one of the emerging renewable energy sources in the world. my country's biomass pellet production and application technology is gradually developing. After the raw materials for making biomass pellets are crushed by the pressure hub and extruded through many through holes of the ring die, the biomass pellets extruded by the pelletizer are discharged from the hopper of the pelletizer located at the lower end of the extrusion ring die. fall. [0003] When the ring die pellet mill presses materials with high fiber content, such as wood chips and other biomass materials, the molding load is much larger than that of pressed feed pellets. In addition, the raw materials of biomass pellets are usually raw materials with extremely low moisture content. T...
