Abstract
Abstract A glass batch wetting system for controlling dust pollution in the atmosphere. Glass batch is uniformly wetted immediately prior to its introduction into a glass melting furnace by a hollow fluid dispensing rotating shaft. The shaft is positioned directly within the flow of batch as it moves from a charge hopper to the furnace opening. The rotation of the shaft and amount of fluid addition are varied with the mass flow rate of glass batch into the furnace.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
IN A SYSTEM FOR WETTING PARTICULATE MATERIALS BEING CHARGED TO A GLASS MELTING FURNACE COMPRISING: A HOUSING FRAME, GUIDE MEANS WITHIN SAID HOUSING FRAME FOR DIRECTING PARTICULATE MATERIALS TO AN OPENING IN SAID GLASS FURNACE, SAID GUIDE MEANS INCLUDING A CHUTE HAVING AN OUTLET OPENING, TRANSPORT MEANS FOR MOVING SAID PARTICULATE MATERIALS ALONG AT LEAST A PORTION OF SAID GUIDE MEANS FROM SAID CHUTE OUTLET OPENING INTO THE FURNACE OPENING. FLUID EMITTER MEANS COMPRISING A ROTATABLE HOLLOW SHAFT LOCATED WITHIN SAID GUIDE MEANS PROXIMATE SAID CHUTE OUTLET OPENING TO DIRECTLY CONTACT SAID PARTICULATE MATERIALS, SAID SHAFT INCLUDING A MULTIPLICITY OF FLUID OUTLET ORIFICES LOCATED ALONG THE LENGTH THEREOF,

Claim 3
Dependent Claim
41 words
The system of claim 1 including a fluid control assembly operatively connected to said fluid conductor means and said drive means and including circuit means to activate said drive means in response to the level of molten glass in said furnace.
Claim 4
Dependent Claim
80 words
The system of claim 2 wherein said fluid control assembly includes a control valve located in said fluid conductor means, a flow meter means positioned in said conductor means downstream from said control valve, and at least one solenoid valve positioned in said conductor means downstream from said flow meter means, said solenoid valve being adapted to open fluid flow when said circuit means activates said drive means to close fluid flow when said circuit means deactivates said drive means.
Claim 5
Dependent Claim
35 words
The system of claim 1 wherein said shaft includes a series of hollow protuberances and said orifices are located on the side of said protuberances facing a direction opposite to the rotation of said shaft.
Claim 6
Dependent Claim
23 words
The system of claim 3 wherein said flow control assembly includes means for introducing a gaseous purging medium into said fluid conductor means.
Claim 7
Dependent Claim
82 words
The system of claim 1 wherein said transport means includes a counterbalanced rotatable pusher assembly pivotably mounted on said housing frame and having a face plate located proximate said guide means and adapted to engage said particulate matter when said assembly is in a forward position, an eccentric shaft with one end journaled to a portion of said pusher assembly offset from where said assembly is mounted on said housing frame and another end in engagement with a drive shaft eccentric means.
Claim 8
Dependent Claim
24 words
The system of claim 4 wherein said protuberances are longitudinally offset from each other and project from about three quadrants of said emitter shaft.
