Abstract

The invention concerns a fluid degassing device for degassing fluids, in particular resins. The device has a fluid supply element for supply of the fluid and a fluid discharge element for discharge of the fluid. Between the supply element and the discharge element there is at least one structural element for breaking down bubbles in the fluid as it flows through the structural element. In addition or alternatively there may be provided at least one profile element, over which the fluid must flow.

First claim

The invention claimed is:

1. A fluid degassing device comprising:
a supply conduit configured to receive resin;
a discharge conduit configured to discharge the resin; and
degassing chambers configured to remove gas in the resin as the resin passes from the supply conduit to the discharge conduit, the degassing chambers including:
a first chamber configured to receive the resin from the supply conduit, the first chamber including at least one first structural element that includes a non-woven material configured to remove at least some gas from the resin as the resin passes through the non-woven material;
a second chamber configured to receive resin from the first chamber, the second chamber including at least one second structural element that includes a mesh through which the resin is passed, the mesh being configured to remove at least some gas from the resin; and
a third chamber in fluid communication with the second chamber and configured to receive resin from the second chamber, the third chamber comprising a wall, a first gap below the wall, and a plurality of convex-shaped elements, wherein the resin flows through the first gap and accumulates in front of a first one of the plurality of convex-shaped elements until the resin flows over an upper edge of the first one of the plurality of convex-shaped elements so that a surface area of the resin increases in size thereby removing gas from the resin.

2. The device according to claim 1 further comprising a separating wall between the first and second chambers that includes at least one second gap.

3. The device according to claim 1 further comprising a separating wall between the second and third chambers that includes at least one third gap.

4. The device according to claim 1 further comprising a pivot axis for pivoting the device.

5. The device according to claim 1 further comprising a mesh element arranged around the discharge element.

6. The fluid degassing device according to claim 3 , wherein the second chamber includes a plurality of struts that extend toward a center portion of the second chamber, the mesh being stretched between the plurality of struts so that the resin flows through the mesh between the plurality of struts.

7. A fluid degassing device comprising:
a supply conduit that receives resin;
a structural member that receives the resin from the supply conduit, the structural member including:
a first chamber that includes non-woven material that removes at least some gas from the resin as the resin passes therethrough,
a second chamber in fluid communication with the first chamber, the second chamber including a mesh that removes at least some gas from the resin as fluid flows through the mesh, and
a third chamber in fluid communication with the second chamber and configured to receive resin from the second chamber, the third chamber including a wall, a first gap below the wall, and a plurality of convex-shaped elements, wherein the resin flows through the first gap and accumulates in front of a first one of the plurality of convex-shaped elements until the resin flows over an upper edge of the first one of the plurality of convex-shaped elements so that a surface area of the resin increases in size thereby removing gas from the resin; and

a discharge conduit that receives the resin from the third chamber of the structural member and discharges the resin.

8. The fluid degassing device according to claim 7 , wherein the first chamber is in fluid communication with the second chamber by a second gap that causes the resin to become thinner as the resin flows from the first chamber to the second chamber.

9. The fluid degassing device according to claim 7 , wherein the second chamber is in fluid communication with the third chamber by a third gap that causes the resin to become thinner as the resin flows from the second chamber to the third chamber.

10. The fluid degassing device according to claim 7 , wherein the third chamber includes a plurality of separating walls to form divided chambers, each divided chamber including one of the plurality of convex-shaped elements, the resin flowing through each of the divided chambers and over the respective plurality of convex-shaped elements.

11. The fluid degassing device according to claim 7 , wherein the second chamber includes a plurality of struts that extend toward a center portion of the second chamber, the mesh being stretched between the plurality of struts so that the resin flows through the mesh between the plurality of struts.
