Definitions

  • This patent application discloses innovations related to glass manufacturing and, more particularly, to delivering glass batch into a glass melter.
  • a submerged combustion melter (SCM) designed for glass manufacturing typically has a roof or sidewall with an inlet for receiving glassmaking materials (“glass batch”) from a glass batch charger, as well as one or more submerged burners that discharge combustion products directly into a glass melt contained within the melter.
  • the sidewalls and sometimes the roof of the melter may be constructed of liquid cooled panels, especially since the glass melt is maintained at a relatively high temperature on the order of 1000°C to 2000°C.
  • a solidified layer of glass is formed on interior surfaces of the liquid cooled panels, which protects the furnace from erosion and corrosion caused by the turbulent molten glass inside the SCM.
  • the turbulent molten glass may also splash around and into the inlet and, once there, can possibly solidify within and at least partially block the inlet. Any such full or partial blockage of the inlet may in turn impede the delivery of the glass batch into the melter.
  • the present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.
  • a glass batch inlet and cleaning device that includes an outer tubular housing including a side inlet, an inner tubular chopper slidable within the outer tubular housing, a cover on the outer tubular housing, and an actuator carried by the cover and coupled to the inner tubular chopper to move the chopper with respect to the outer tubular housing.
  • a glass batch inlet and cleaning device that includes an outer tubular housing extending from an upper end to a lower end and including a side inlet, the lower end of the housing defining an outlet, and an inner tubular chopper including a side inlet relief in registration with the side inlet of the outer tubular housing.
  • the device also includes a cover coupled to the upper end of the outer tubular housing opposite of the outlet, and an actuator carried by the cover and coupled to the inner tubular chopper to move the chopper with respect to the outer tubular housing.
  • a method of using a glass batch inlet and cleaning device includes providing a glass batch inlet and cleaning device that includes an outer tubular housing that defines an interior and an outlet from the device and that further includes a side inlet.
  • the glass batch and cleaning device also includes a chopper slidable within the outer tubular housing.
  • Another step of the method includes passing glass batch through the glass batch inlet and cleaning device and into a glass melter. In so doing, the glass batch is introduced into the interior of the outer tubular housing through the side inlet and is then passed through the interior and out of the outlet of the housing and into the glass melter through an inlet of the glass melter.
  • Yet another step of the method includes activating a actuator to centrally actuate inner tubular chopper from a raised position, in which a chopping end of the inner tubular chopper is within the outer tubular housing, to a lowered position, in which the chopping end extends out of the outer tubular housing and beyond the outlet.
  • FIG. l is a fragmentary perspective view of a glass batch charger, a glass melter, and a glass batch inlet and cleaning device that conveys glass batch from the glass batch charger to the glass melter in accordance with an illustrative embodiment of the present disclosure.
  • FIG. 2A is a fragmentary, longitudinal sectional view of the batch inlet and cleaning device and portions of the glass batch charger and glass melter of FIG. 1, and illustrating a chopper of the device in a retracted position.
  • FIG. 2B is the device shown in FIG. 2A, illustrating the chopper in an advanced position.
  • FIG. 3 is an enlarged, fragmentary, quarter-sectional, perspective view of a portion of the batch inlet and cleaning device of FIG. 1, illustrating a coupling between an actuator and the chopper.
  • FIG. 4 is an enlarged, fragmentary, perspective view of a chopper anti -rotational feature of the batch inlet and cleaning device of FIG. 1.
  • FIG. 5 is a perspective view of the device of FIG. 1, viewed from a different angle.
  • a glass batch inlet and cleaning device is described below with reference to its use between a glass batch charger and a glass melter.
  • the device includes an inlet that receives glass batch from the charger and an outlet that transmits the glass batch into the melter, and is configured to clear solidified or frozen glass from the outlet.
  • Prior batch inlet and cleaning devices have been implemented and work satisfactorily, but those devices have multiple side-mounted actuators that may lead to leakage of glass batch, may necessitate use of guarding, and/or may require synchronization between the multiple side-mounted actuators.
  • the presently disclosed batch inlet and cleaning device has a top-mounted actuator that represents one improvement, among others, over such prior devices.
  • FIG. 1 illustrates an exterior view of a glass batch inlet and cleaning device 10 in accordance with an illustrative embodiment of the present disclosure.
  • the device 10 is positioned between a batch charger 12 and a glass melter 14.
  • the batch charger 12 has a charger outlet 16 that may include a conduit extending along a longitudinal axis that may be horizontally oriented to deliver glass batch horizontally across and into an outer tubular housing 18 of the device 10 via a side inlet 20 of the housing 18.

  • the charger outlet 16 may be carried radially within the side inlet 20 and may be sealed thereto via a seal coupling 17, or may be coupled to the side inlet 20 in any other manner suitable to convey glass batch.
  • the batch charger 12 delivers the glass batch through the charger outlet 16, into and through the device 10 via the side inlet 20 and housing 18, through a top wall or roof 22 of the melter 14, and down into an interior of the melter 14.
  • the housing 18 has an outer wall 24 that forms an interior 26 of the tubular housing 18, and the glass batch passes from the side inlet 20 into the interior 26 of the tubular housing 18.
  • the outer wall 24 extends from the upper end of the housing 18 to the lower end of the housing 18.

Additionally, the upper viewing ports 30 can be used by an operator to observe the introduction of batch into the device 10 or to observe the operation of the device 10 without danger of being pinched or otherwise hurt by movement of various other components of the device 10. Although only one upper viewing port 30 is shown in FIG. 3, at least one other viewing port may be provided, for example, diametrically opposite therefrom.
  • the device 10 also includes a side cleanout port 34, through which the interior 26 of the device 10 is accessible.
