Abstract

Provided is a gas-blowing vaporizing and drying device for blowing gas at a solution containing a target component, and thus nebulizing the solution to promote vaporization of the solvent while dropping the solution into the collection container, in which contamination does not occur even if different solutes are successively powderized. In the gas-blowing vaporizing and drying device according to the present invention, a cap 20 to be fitted to the upper opening of a collection container body 19 includes: a solution-introducing tube 20A for introducing a solution supplied from a passage 14, into a collection container 21; a gas-introducing tube 20B for introducing a gas supplied from a passage 22, into the collection container 21; and an exhaust port 20C. Further, the exhaust port 20C includes a filter 20D for preventing the powderized solute from passing therethrough.

First claim

The invention claimed is:

1. A gas-blowing vaporizing and drying device, comprising:
a collection container for collecting a target component; and
a collector head for supplying gas and a solution containing the target component into the collection container, the gas-blowing vaporizing and drying device being for blowing the gas at the solution, and thus nebulizing the solution to promote vaporization of a solvent while dropping the solution into the collection container, in which
the collector head includes:
a solution connection tube through which the solution flows; and
a gas connection tube through which the gas flows;

the collection container includes:
a collection container body;
a lid including:
a solution-introducing tube being attachable to and detachable from the solution connection tube and being fixed to the lid, and an inlet end of the solution-introducing tube protrudes from the collection container to be connected to an outlet end of the solution connection tube; and
a gas-introducing tube being attachable to and detachable from the gas connection tube and being fixed to the lid, and an inlet end of the gas-introducing tube protrudes from the collection container to be connected to an outlet end of the gas connection tube; and
an exhaust port; and

a collector head drive mechanism for connecting or disconnecting the solution connection tube and the solution-introducing tube, and for connecting or disconnecting the gas connection tube and the gas-introducing tube, by vertically moving the collector head.

2. The gas-blowing vaporizing and drying device according to claim 1 , wherein the exhaust port includes a filter.

3. The gas-blowing vaporizing and drying device according to claim 1 , further comprising:
gas-introducing tube washing means including:
a passage connected to a gas passage for introducing the gas into the gas connecting tube in a middle thereof; and
a liquid-sending pump for feeding a washing liquid to the gas-introducing tube through the passage and the gas passage.

4. The gas-blowing vaporizing and drying device according to claim 1 , wherein
the solution-introducing tube and the gas-introducing tube have a double-tube structure in which the solution-introducing tube is an inner tube while the gas-introducing tube is an outer tube, and
an outlet end of the solution-introducing tube protrudes from an outlet end of the gas-introducing tube.

5. The gas-blowing vaporizing and drying device according to claim 4 , wherein a distance between an outlet end of the solution-introducing tube and an outlet end of the gas-introducing tube is 1.5 times or more a given distance at which a deposited substance of the solution grows along an outer circumferential surface of the solution-introducing tube from the outlet end of the solution-introducing tube, the given distance being assumed based on surface tension of the solvent and a contact angle of the solvent to the outer circumferential surface of the solution-introducing tube.

6. The gas-blowing vaporizing and drying device according to claim 1 , wherein the solution-introducing tube is made of a fluorine resin material.

7. The gas-blowing vaporizing and drying device according to claim 1 , wherein an end face of the outlet end of the solution-introducing tube is orthogonal to an axis of the solution-introducing tube.

8. The gas-blowing vaporizing and drying device according to claim 1 , further comprising:
a housing unit for housing the collection container, the housing unit being fixed at a predetermined position; and
fixing means for fixing the collection container to the housing unit, the fixing means being provided to any one or both of the collection container and the housing unit.

9. The gas-blowing vaporizing and drying device according to claim 8 , wherein
an outer circumferential surface of the lid and an inner circumferential surface of the housing unit include a screw thread and a thread groove corresponding to each other,
an inner circumferential surface of the lid and an outer circumferential surface of the collection container body include a screw thread and a thread groove corresponding to each other, and
axes and turn directions of a screw pair for fixing the lid and the collection container body and a screw pair for fixing the lid and the housing unit are the same as each other.
