Abstract

Disclosed are a defoaming device and a method of defoaming. The defoaming device includes a container having a side wall, a liquid flowing platform that is placed inside the container wherein the liquid flowing platform has a substantial same shape of the side wall and the liquid flowing platform and the side wall has a gap in between, and a solution inflow part attached to the container wherein the solution inflow part is used for allowing a liquid solution to enter the container; and a lifting apparatus attached to the container, where the lifting apparatus attaches to the liquid flowing platform inside the container, and the lifting apparatus is capable of driving the liquid flowing platform to move along the side wall of the container for defoaming the liquid solution when the liquid solution passes through the gap between the liquid flowing platform and the side wall.

First claim

1 . A defoaming device comprising:
a container comprising a side wall, a liquid flowing platform inside the container, wherein:
the liquid flowing platform has a substantial same shape of the side wall;
the liquid flowing platform and the side wall has a gap in between;
a solution inflow part attached to the container; and
the solution inflow part is configured to allow a liquid solution to enter the container; and
a lifting apparatus attached to the container, wherein:
the lifting apparatus attaches to the liquid flowing platform inside the container, and
the lifting apparatus is capable of driving the liquid flowing platform to move along the side wall of the container for defoaming the liquid solution when the liquid solution passes through the gap between the liquid flowing platform and the side wall.

2 . The defoaming device according to claim 1 , wherein the lifting apparatus is capable of turning the liquid flowing platform to a substantially 90-degree inside the container while the liquid flowing platform is driven to move along the side wall.

3 . The defoaming device according to claim 1 , further comprising a vacuum pump attached to the container wherein the container is a contained container and has a substantial vacuum space inside the container created by the vacuum pump.

4 . The defoaming device according to claim 1 , further comprising heating wires that are attached the container, wherein the heating wires are capable of heating the liquid solution inside the container to a certain temperature.

5 . The defoaming device according to claim 4 , wherein the heating wires are placed inside the liquid flowing platform.

6 . The defoaming device according to claim 1 , further comprising a solution stirrer that is placed inside the container, wherein the solution stirrer is capable of stirring the liquid solution inside the container for defoaming the liquid solution.

7 . The defoaming device according to claim 1 , wherein the liquid flowing platform has a conical surface, wherein the liquid flowing platform has a thickness that is gradually reduced from a center of the liquid flowing platform to an edge of the liquid flowing platform, and the gap is between the edge and the side wall.

8 . The defoaming device according to claim 7 , wherein the conical surface of the liquid flowing platform comprises at least two sections, wherein one of the at least two sections has a wider gap than the other one of the at least two sections, and the two sections are used for defoaming different sizes of foams.

9 . The defoaming device according to claim 1 , further comprising two fixed positions for the liquid flowing platform, wherein two fixed positions are associated with the container and the liquid flowing platform is moved along the side wall between the two fixed positions.

10 . The defoaming device according to claim 10 , wherein one of the two fixed positions is defined by a post that is placed inside the contained and is attached to one end of the contained, and the other one of the two fixed positions is defined by a sensor that is placed on the other end of the contained, wherein the sensor is capable of detecting a moving position of the liquid flowing platform and is capable of instructing the lifting apparatus to stop driving the liquid flowing platform to move.

11 . A liquid flowing platform, comprising:
a center point and an edge, wherein:
the liquid flowing platform has a conical surface;
the liquid flowing platform has a thickness that is gradually reduced from
the center point of the liquid flowing platform to the edge;
the liquid flowing platform is capable of being attached inside a container; and
the edge is substantially matched a side wall of the container such that a lifting apparatus attached to the container is capable of driving the liquid flowing platform to move along the side wall of the container to defoam a liquid solution inside the container when the liquid solution passes through a gap between the edge and the side wall.

12 . The liquid flowing platform according claim 11 , wherein the conical surface of the liquid flowing platform comprises at least two sections, wherein one of the at least two sections has a wider gap than the other one of the at least two sections, and the two sections are used for defoaming different sizes of foams.

13 . The liquid flowing platform according claim 11 , wherein the liquid flowing platform is capable of being turned into a substantially 90-degree inside the container while the liquid flowing platform is driven to move along the side wall.

14 . A method of defoaming by using a defoaming device, the method comprising:
providing a container comprising a side wall, a liquid flowing platform that is placed inside the container wherein the liquid flowing platform has a substantial same shape of the side wall and the liquid flowing platform and the side wall has a gap in between, and a solution inflow part attached to the container wherein the solution inflow part is used for allowing a liquid solution to enter the container; providing a lifting apparatus attached to the container, wherein the lifting apparatus attaches to the liquid flowing platform inside the container, and the lifting apparatus is capable of driving the liquid flowing platform to move along the side wall of the container for defoaming the liquid solution when the liquid solution passes through the gap between the liquid flowing platform and the side wall; importing a liquid solution to be defoamed by the liquid flowing platform, wherein the liquid solution flows through the gap to a bottom of the container; and lifting the liquid solution by the lifting apparatus when driving the liquid flowing platform to move along the side wall of the container.

15 . The method according to claim 14 , further comprising turning the liquid flowing platform to a substantially 90-degree inside the container while the liquid flowing platform is driven to move along the side wall.

16 . The method according to claim 14 , further comprising sealing the container, and vacuuming the container by a vacuum pump.

17 . The method according to claim 14 , further comprising heating the liquid solution inside the container to a certain temperature by heating wires.

18 . The method according to claim 14 , further comprising stirring the liquid solution inside the container for defoaming the liquid solution by a solution stirrer.
