SYSTEM FOR INTRODUCING FOAM WITH VARIABLE PORT INSERTS FOR DEVICE MIXING AND DISTRIBUTING SUSPENSION Russian patent published in 2019 - IPC B28C5/06 B01F5/04 B28B19/00 

FIELD: processing of cement, clay and stone.

SUBSTANCE: system (301, 701) for introduction of foam for use in making binding materials includes housing (305, 605) for introducing foam, as well as first and second inserts (100, 400, 200, 500) of the port. Foam introduction body (305, 605) forms suspension channel (310, 610) and port channel (315, 615) having outlet port (317, 617) communicated via fluid medium with suspension channel (310, 610). First and second port inserts (100, 400, 200, 500) respectively form first and second foam channels (115, 415; 215, 515) having first and second dimensions (Ø₁, Ø₄; Ø₃, Ø₄, Ø₅) holes, which are different. First and second inserts (100, 400, 200, 500) of the port are configured to be detachably mounted in the foam introduction body (305, 605) such that the corresponding foam channel (115, 415, 215, 515) communicates via a fluid medium with channel (310, 610) for suspension by means of port (317, 617) of channel (315, 615) of port. First port (100, 400) of port can be replaced with second port (200, 500) of port to facilitate change of foam pressure flowing in specific insert (100, 400, 200, 500) of port and introduced into binder suspension, moving in channel (310, 610) for suspension.

EFFECT: disclosed is a system for introducing foam with variable port inserts for mixing and distributing suspension device.
