Abstract

The present invention includes a first injection tube for supplying a colloidal medium, a storage part connected to the first injection tube for receiving the colloidal medium through the first injection tube, a second injection tube connected to the storage part for supplying a colloid, a discharge tube connected to both the storage part and the second injection tube for discharging the colloidal medium coming from the storage part and the colloid coming from the second injection tube, and a free surface inversion part for inverting the free surface of the liquid in the second injection tube so as to mix the colloidal medium and the colloid in the discharge tube.

First claim

The invention claimed is:

1. An apparatus for producing a composite material, comprising:
a first injection tube supplying a dispersion medium;
a reservoir connected to the first injection tube and receiving the dispersion medium through the first injection tube;
a second injection tube connected to the reservoir and supplying dispersion particles;
a discharge tube connected to the reservoir and the second injection tube and discharging a mixture of the dispersion medium supplied from the reservoir and the dispersion particles supplied from the second injection tube; and
a free surface inversion unit directing a free surface of a liquid in the second injection tube vertically downward such that the dispersion medium and the dispersion particles are mixed with each other inside the discharge tube;
wherein the free surface inversion unit comprises:
a coil generating an induced current inside the reservoir;
an electromagnet disposed at a connection portion between the second injection tube and the discharge tube.

2. The apparatus according to claim 1 , wherein the reservoir is formed of a closed loop pipe, and the discharge tube communicates with the reservoir and extends upward therefrom.

3. The apparatus according to claim 1 , wherein the electromagnet controls Lorentz force by generating a magnetic field in a direction perpendicular to the induced current of the coil.

4. The apparatus according to claim 1 , further comprising:
a cooling unit provided on the discharge tube and cooling a composite material, is the mixture of the dispersion medium and the dispersion particles; and
an extraction unit drawing up the composite material discharged from the cooling unit.
