Problems solved by technology

However, there is a common problem in the above two granulator structures, that is, after the roller granulation is completed, due to extrusion, some particles adhere to the surface of the roller and are not easy to fall off, which affects the granulation efficiency and granulation quality.

Abstract

The invention discloses an internal air injection discharging double-roller granulator. A roller and a rotary shaft are hollow and are interconnected; one end of the hollow rotary shaft is connected with an air pump; a plurality of shaft air outlet holes are formed in one section, in the hollow roller, of the hollow rotary shaft; roller air outlet holes are formed in the bottom of a surface groove of the hollow roller; the roller air outlet holes are communicated with the hollow roller. Consequently, the airflow discharged by the air pump reaches the hollow roller through the hollow rotary shaft and is ejected out through the shaft outlet holes and the roller air outlet holes in turn, so that particles are separated from the groove in the surface of the roller and enter a collecting device; after granulating once by relatively squeezing the roller once, no particle remains on the surface, so that the next granulation efficiency or the next granulation quality is not affected.

Description

technical field [0001] The invention relates to the technical field of granulation, in particular to an internal jet unloading double-roll granulator. Background technique [0002] Granulator is a molding machine that can make materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. In the prior art, grooves are provided on the surface of the two rollers of the traditional double-roller granulator, and the two grooves correspond one by one to form a granulation space. A screw rod is set in the feeding hopper, and through the rotation of the screw rod, The material is forcibly fed between the two rollers, and the two rollers move towards each other to extrude the material to complete the granulation process. However, the above-mentioned double-roll granulator needs to be equipped with a screw rod, an...
