SPHEROPLASTIC PRODUCTION LINE Russian patent published in 2019 - IPC B29C70/66 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of process equipment for making syntactical materials, including filled ones, such as spheroplastics. Spheroplastic production line includes a microsphere supply line with a microsphere container and a dispenser connected to the supply bins, which are connected to the evacuation system, binder line and hardener line with binder and curing agent feed sources, dosing pumps, binder line mixing devices and curing agent line in form of double-screw mixers, interacting screws of which are differently directed, each auger comprises zones, in which step pitch of each next auger zone is less than step pitch of previous screw zone, between screw zones there are roller sections, mixing head, which rotor is equipped with radial rows of plates, which alternate with radial rows of stator plates of mixing head, connecting their pipelines. In points of interaction of augers of mixing devices of binder line and hardener line distance between maximum diameter of one screw and minimum diameter of screw interacting with it is within 1.5<d<3.0, distance between screws and housing is within 1.5<d<3.0, where d is maximum diameter of microspheres. On the binder line and/or on the hardener line, the binder feed source and/or the hardener supply source and/or the mixing device and/or the mixing head and/or the pipelines connecting them are equipped with a heating system. Besides, line is equipped with system of chemical foaming agents supply connected with mixing head, and binder and/or curing agent supply sources are made in the form of flow bins with flow mixers.

EFFECT: high quality of the obtained spheroplastic and high efficiency of the line for producing spheroplastic.
