Abstract

Disclosed is a dissolution mixer, which includes: a dissolution bath configured to accommodate a powder and a solvent for dissolving the powder; a powder input unit located at an outer side of the dissolution bath; an impeller installed to be rotatable inside the dissolution bath; and an anchor located inside the dissolution bath and having a passage of the powder inputted by the powder input unit and a powder spouting hole connected to the passage.

First claim

What is claimed is:

1. A dissolution mixer, comprising:
a dissolution bath configured to accommodate a powder and a solvent for dissolving the powder;
a powder input unit located at an outer side of the dissolution bath;
an impeller installed to be rotatable inside the dissolution bath; and
an anchor located inside the dissolution bath and having a passage of the powder inputted by the powder input unit and at least one powder spouting hole connected to the passage,
wherein the anchor includes: an upper frame connected to the powder input unit; a lower frame located below the upper frame; and a pair of connection frames configured to connect the upper frame and the lower frame; such that the upper frame, the lower frame, and the pair of connection frames form four sides of a rectangular frame shape.

2. The dissolution mixer according to claim 1 , further comprising: a dissolved material discharging unit connected to a lower portion of the dissolution bath.

3. The dissolution mixer according to claim 1 , wherein the at least one powder spouting hole is formed in the lower frame.

4. The dissolution mixer according to claim 3 , wherein a center portion of the lower frame has a donut shape.

5. The dissolution mixer according to claim 4 , wherein the at least one powder spouting hole is formed in both the center portion of the lower frame and a region of the lower frame other than the center portion.

6. The dissolution mixer according to claim 4 , wherein the at least one powder spouting hole is formed only in the center portion of the lower frame.

7. The dissolution mixer according to claim 1 , wherein the anchor is installed to be rotatable inside the dissolution bath.

8. The dissolution mixer according to claim 7 , wherein a rotating direction of the anchor is identical to a rotating direction of the impeller.

9. The dissolution mixer according to claim 8 , wherein a rotating speed of the anchor is slower than a rotating speed of the impeller.

10. The dissolution mixer according to claim 7 , wherein the impeller rotates based on a rotation shaft and the anchor rotates based on the same rotation shaft.
