Abstract

A glass product manufacturing apparatus and a method of manufacturing glass products are disclosed. The glass product manufacturing apparatus includes a melting vessel, a support grating configured to support an outer wall of the melting vessel, a cooling module configured to cool the outer wall of the melting vessel, on the support grating, and a support frame detachably fastened to the support grating to limit a movement of the support grating. By using the glass product manufacturing apparatus and the method of manufacturing glass products, high energy efficiency is maintained even when operating, and a defect rate is reduced.

First claim

What is claimed is:

1. A glass product manufacturing apparatus comprising: a melting vessel; a support grating configured to support an outer wall of the melting vessel and offsetting a force of the melting glass pushing on the outer wall, the support grating comprising a plurality of openings through which radiant energy emitted from the outer wall passes; a cooling module attached to, and in contact with, the support grating and configured to cool the outer wall of the melting vessel, the support grating provided between the cooling module and the outer wall, the cooling module comprising: a cooling medium inlet through which a heat transfer medium fluid is received within the cooling module; a cooling medium outlet in fluid communication with the cooling medium inlet, wherein all of the heat transfer medium fluid that exits the cooling module exits through the cooling medium outlet; and a recessed portion defining an opening; and a support frame detachably fastened to the support grating to limit a movement of the support grating, the support frame comprising a beam structure and a support structure, the support structure extending laterally from the beam structure, through the opening of the recessed portion, and to the support grating, wherein the support structure is detachably fastened to the support grating and applies a force to the support grating-, wherein a difference in temperature of the heat transfer medium fluid entering through the cooling medium inlet and exiting through the cooling medium outlet is within a range from about 70 C to about 150 C.

2. The glass product manufacturing apparatus of claim 1 , wherein the support frame comprises a first support structure and a second support structure, and each of the first support structure and the second support structure is independently and detachably attached on the support grating.

3. The glass product manufacturing apparatus of claim 2 , wherein the cooling module is configured to be attached to or detached from the support grating while the first support structure is fastened to the support grating and the second support structure is detached from the support grating.

4. The glass product manufacturing apparatus of claim 3 , wherein the cooling module is configured to be detached from or attached to the support grating while the melting vessel is operating, and wherein the support structure is not in contact with the cooling module while extending through the opening of the recessed portion.

5. The glass product manufacturing apparatus of claim 4 , wherein
the cooling medium outlet are located on a rear face of the cooling module that is opposite, and facing away from, the support grating, and wherein an area of the outer wall that is overlapped by the cooling module is within about 40% to about 90% of a total area of the outer wall.

6. The glass product manufacturing apparatus of claim 1 , wherein the beam structure comprises: a horizontal beam structure extending in a horizontal direction along the outer wall of the melting vessel; and a vertical beam structure fastened and fixed to the horizontal beam structure.

7. The glass product manufacturing apparatus of claim 1 , wherein the melting vessel includes a gas heating zone and an electric heating zone, and the cooling module is disposed adjacent to the electric heating zone.

8. The glass product manufacturing apparatus of claim 1 , wherein the cooling module cools the outer wall of the melting vessel by a radiation through the support grating.

9. The glass product manufacturing apparatus of claim 8 , wherein the cooling module is provided on a back wall of the melting vessel and is not provided on another sidewall.

10. The glass product manufacturing apparatus of claim 1 , wherein the support frame comprises:
a first beam structure and a second beam structure along corresponding outer walls of the melting vessel;
a first support structure and a second support structure horizontally extending from the first beam structure and fastened to the support grating; and
a third support structure and a fourth support structure horizontally extending from the second beam structure and fastened to the support grating.

11. The glass product manufacturing apparatus of claim 10 , wherein at least one of the first support structure, the second support structure, the third support structure, and the fourth support structure is detachably attached on the support grating.

12. The glass product manufacturing apparatus of claim 11 , wherein the cooling module is disposed between the support grating and the support frame and is fixed to the support grating.

13. The glass product manufacturing apparatus of claim 12 , wherein the cooling module comprises a single outlet through which the heat transfer medium fluid exits the cooling module.

14. The glass product manufacturing apparatus of claim 13 , further comprising a fixing member that detachably fixes the cooling module to the support grating, and wherein the cooling module is configured to be moved relative to the support grating and the support frame into a space between the support grating and the support frame.
