Abstract
A mixing module includes two inlets, an integrator, and a valve member. The integrator has two chambers each having a near end and a far end, and the valve member is movable between two positions. One of the inlets is connected to the near end of one of the chambers and the other inlet is connected to the near end of the other chamber when the valve is in one position. When the valve is in the other position, one of the inlets is disconnected from the chambers and the near ends of the chambers are connected.
Claims20
A mixing module comprising:
- a first inlet;
- a second inlet;
- a first plug member downstream of the first inlet and comprising a first seat portion;
- a second plug member downstream of the second inlet and comprising a second seat portion;
- an integrator downstream of the first and second plug members, the integrator comprising:
- a first chamber with a first proximal end and a first distal end;
- and
- a second chamber with a second proximal end and a second distal end;
- and
- a valve member downstream of the first and second plug members that is movable between a first position and a second position;
- wherein the valve member has a first side complementary to a shape of the first seat portion of the first plug member and a second side complementary to a shape of the second seat portion of the second plug member.

A method of operating a mixing module, the method comprising:
- positioning a valve member in a mix position;
- flowing resin through a resin inlet into a resin chamber of an integrator, the resin flowing from the resin inlet, through a first flow path in a first plug member downstream of the resin inlet, and into the integrator downstream of the first plug member;
- flowing catalyst through a catalyst inlet into a catalyst chamber of the integrator, the catalyst flowing from the catalyst inlet, through a second flow path in a second plug member downstream of the catalyst inlet, and into the integrator downstream of the second plug member;
- and
- mixing the resin and the catalyst;
- wherein the valve member has a first side complementary to a shape of a first seat portion of the first plug member and a second side complementary to a shape of a second seat portion of the second plug member.
