Abstract

A glassware manufacturing system, waste handling system, and method are disclosed. The glassware manufacturing system, in accordance with one aspect of the disclosure, comprises an architectural installation having a forming floor and no basement beneath the forming floor; a glassware forming machine carried on the forming floor; a molten glass feeder configured to provide molten glass to the glassware forming machine; and a glassware manufacturing waste handling system including a sump pit in the forming floor, and a waste liquid trench substantially surrounding the glassware forming machine and flowing to the sump pit. Also, a cullet material handler and/or a molten waste glass sluice may be configured to receive molten glass and unused molten glass streams from the molten glass feeder and hot glassware rejects from the glassware forming machine.

First claim

The invention claimed is:

1 . A glassware manufacturing system, comprising:
an architectural installation having a forming floor and no basement beneath the forming floor; a glassware forming machine carried on the forming floor; a molten glass feeder configured to provide molten glass to the glassware forming machine; and a glassware manufacturing waste handling system, including:
a sump pit in the forming floor;
a waste liquid trench substantially surrounding the glassware forming machine and flowing to the sump pit; and
at least one of a cullet material handler or a molten waste glass sluice, configured to receive molten glass from the molten glass feeder and hot glassware rejects from the glassware forming machine.

2 . The system of claim 1 , wherein the forming floor is sloped or crowned from the glassware forming machine to the waste liquid trench.

3 . The system of claim 1 , wherein the glassware forming machine is an individual section machine.

4 . The system of claim 1 , wherein the cullet material handler and/or the molten waste glass sluice is at least partially recessed in a cullet trench in the forming floor.

5 . The system of claim 4 , further comprising:
an enclosure over the cullet trench to establish a cullet trench conduit; and steam removal ductwork in fluid communication with the cullet trench conduit to remove steam from the cullet trench conduit.

6 . The system of claim 1 , wherein the cullet material handler and/or the molten waste glass sluice is mounted to the forming floor and disposed at a level of the forming floor.

7 . The system of claim 1 , wherein the cullet material handler includes a steel-hinged drag chain.

8 . The system of claim 1 , wherein liquid waste collected by the sump pit is recycled to the system.

9 . The system of claim 1 , further comprising:
an annealing lehr downstream of the glassware forming machine.

10 . The system of claim 9 , further comprising:
a cold cullet return conveyor on the forming floor configured to receive cold glassware rejects from a location downstream of the annealing lehr.

11 . The system of claim 10 , further comprising:
a reject conveyor configured to transport the hot glassware rejects from the glassware forming machine to the cullet material handler.

12 . The system of claim 11 , further comprising:
a cullet crusher on the forming floor.

13 . The system of claim 12 , wherein the cullet crusher is disposed between the cullet material handler and a cold cullet return conveyor to produce cullet from the cold glassware rejects and direct the cullet to the cullet material handler and/or the molten waste glass sluice.

14 . The system of claim 13 , further comprising:
a waste molten glass chute configured to direct rejected mold charges from the glassware forming machine to the cullet material handler and/or the molten waste glass sluice.

15 . The system of claim 11 , wherein the reject conveyor includes high temperature plating.

16 . The system of claim 1 , further comprising:
an annealing lehr downstream of the glassware forming machine; a cold cullet return conveyor on the forming floor and configured to receive cold glassware rejects from a location downstream of the annealing lehr; and a cullet crusher disposed between the cullet material handler and a cold cullet return conveyor to produce cullet from the cold glassware rejects and direct the cullet to the cullet material handler and/or the molten waste glass sluice.

17 . The system of claim 1 , further comprising:
a reject conveyor configured to transport the hot glassware rejects from the glassware forming machine to the cullet material handler; and a waste molten glass chute configured to direct rejected mold charges from the glassware forming machine to the cullet material handler and/or the molten waste glass sluice.

18 . The system of claim 1 , further comprising:
an annealing lehr downstream of the glassware forming machine; a cold cullet return conveyor on the forming floor and configured to receive cold glassware rejects from a location downstream of the annealing lehr; a cullet crusher disposed between the cullet material handler and a cold cullet return conveyor to produce cullet from the cold glassware rejects and direct the cullet to the cullet material handler and/or the molten waste glass sluice; a reject conveyor configured to transport the hot glassware rejects from the glassware forming machine to the cullet material handler; and a waste molten glass chute configured to direct rejected mold charges from the glassware forming machine to the cullet material handler and/or the molten waste glass sluice.

19 . A glassware manufacturing waste handling system, comprising:
a sump pit in a forming floor of an architectural installation, where the architectural installation has no basement beneath the forming floor; a waste liquid trench in the forming floor and substantially surrounding a glassware forming machine carried on the forming floor, the waste liquid trench flowing to the sump pit; and at least one of a cullet material handler or a molten waste glass sluice, configured to receive molten glass from a molten glass feeder and hot glassware rejects from the glassware forming machine.

20 . The system of claim 19 , wherein the forming floor is sloped from the glassware forming machine to the waste liquid trench.

21 . The system of claim 19 , wherein liquid waste collected by the sump pit is recycled to a glassware manufacturing system.

22 . The system of claim 19 , wherein the forming floor is sloped or crowned from the glassware forming machine to the waste liquid trench.

23 . The system of claim 19 , wherein the cullet material handler and/or the molten waste glass sluice is at least partially recessed in a cullet trench in the forming floor.

24 . The system of claim 23 , further comprising:
an enclosure over the cullet trench to establish a cullet trench conduit; and steam removal ductwork in fluid communication with the cullet trench conduit to remove steam from the cullet trench conduit.

25 . The system of claim 19 , wherein the cullet material handler and/or the molten waste glass sluice is mounted to the forming floor and disposed at a level of the forming floor.

26 . A glassware manufacturing system, comprising:
an architectural installation having a forming floor; a glassware forming machine carried on the forming floor; a molten glass feeder configured to provide molten glass to the glassware forming machine; and a glassware manufacturing waste handling system, including:
a sump pit in the forming floor;
a waste liquid trench in the forming floor and substantially surrounding the glassware forming machine and flowing to the sump pit; and
a cullet material handler configured to receive hot glassware rejects from the glassware forming machine.

27 . The system of claim 26 , wherein the glassware manufacturing waste handling system also includes:
a molten waste glass sluice configured to receive molten glass from the molten glass feeder.

28 . The system of claim 27 , wherein the glassware manufacturing waste handling system also includes:
