Abstract

A chute type monomer dispenser is provided in the present disclosure. The chute type monomer dispenser includes a chute dispenser installed to be slanted in a direction of a polymerization apparatus, the chute dispenser is configured to inject a monomer to the polymerization apparatus through an injection pipe having an injection portion having an opening at an upper portion of the chute dispenser; and an injector configured to inject an initiator and a foaming agent to the injection portion.

First claim

The invention claimed is:

1. A chute type monomer dispenser comprising:
a chute dispenser installed to be slanted in a direction of a polymerization apparatus, the chute dispenser configured to inject a monomer to the polymerization apparatus through an injection pipe;
an injection portion having an opening at an upper portion of the chute dispenser; and
an injector configured to inject an initiator and a foaming agent to the injection portion.

2. The chute type monomer dispenser of claim 1 , wherein
the chute dispenser further comprises:
a dispenser body on which the monomer is moved in the direction of the polymerization apparatus; and
guide portions formed at sides of the dispenser body configured to guild a movement of the monomer.

3. The chute type monomer dispenser of claim 2 , wherein
the dispenser body has
a slanted movement portion on which the monomer, the initiator, and the foaming agent are moved in the direction of the polymerization apparatus.

4. The chute type monomer dispenser of claim 3 , wherein
the guide portions further comprises:
a first guide protrusion protruding at a first edge of a first side of the slanted movement portion; and
a second guide protrusion protruding at a second edge of a second side of the slanted movement portion, the second side being opposed to the first side.

5. The chute type monomer dispenser of claim 4 , wherein
the slanted movement portion is formed in a fan shape from a portion where the first guide protrusion and the second guide protrusion are connected to each other.

6. The chute type monomer dispenser of claim 1 , wherein
the injection pipe has an opened fan-shaped portion where the monomer is discharged to the injection portion.

7. The chute type monomer dispenser of claim 1 , wherein
the injector injects the initiator and the foaming agent to a portion of the injection portion of the chute dispenser in a spray manner.
