Batch inlet and cleaning device for glass melter
A glass melter batch inlet and cleaning device and related methods of its operation are disclosed. The glass melter batch inlet and cleaning device includes an outer tubular housing including a side inlet, an inner tubular chopper including a side inlet relief in registration with the side inlet of the outer tubular housing, and at least one actuator extending alongside the outer tubular housing and coupled to the inner tubular chopper to move the chopper with respect to the outer tubular housing.
1. A glass melter batch inlet and cleaning device, comprising:
an outer tubular housing including a side inlet;
an inner tubular chopper including a side inlet relief in registration with the side inlet of the outer tubular housing; and
at least one actuator extending alongside the outer tubular housing and coupled to the inner tubular chopper to move the chopper with respect to the outer tubular housing.
2. The device of claim 1 , wherein the outer tubular housing also includes a side cleanout port through which an interior of the device is accessible, and wherein the inner tubular chopper also includes a side cleanout relief in registration with the side cleanout port of the outer tubular housing.
3. The device of claim 1 , further comprising an upper viewing port through which the side inlet and the inner tubular chopper are viewable.
4. The device of claim 3 , wherein the upper viewing port includes one of a mesh or transparent material.
5. The device of claim 3 , further comprising a cover located above the upper viewing port.
6. The device of claim 1 , wherein the outer tubular housing has an outlet for passing glass batch into a melter, and the inner tubular chopper has a chopping end and includes a first position in which the chopping end is maintained in the outer tubular housing and a second position in which the chopping end extends out of the outer tubular housing through the outlet.
7. The device of claim 6 , further comprising an arm extending through the inner tubular chopper, and wherein the at least one actuator comprises a rod coupled to the arm, the rod being in an extended state when the inner tubular chopper is in the first position and being in a retracted state when the inner tubular chopper is in the second position so that the at least one actuator is arranged to pull the inner tubular chopper from the first position to the second position.
8. The device of claim 7 , wherein the at least one actuator is a first actuator and a second actuator both extending alongside the outer tubular housing, both of the first and second actuators being arranged to pull the inner tubular chopper from the first position to the second position.
9. The device of claim 1 , wherein the at least one actuator is connected to a safety guard to maintain the actuator.
10. The device of claim 6 , further comprising at least one control valve coupled to the inner tubular chopper and the at least one actuator, and wherein the control valve is for controlling a speed of the inner tubular chopper as it moves between the first and second positions.
11. The device of claim 10 , wherein the at least one control valve is a first control valve and a second control valve, both valves being coupled to the inner tubular chopper and the first and second actuators, respectively, and wherein the control valves are for controlling the speed of the inner tubular chopper.
12. The device of claim 6 , wherein the inner tubular chopper is hollow for the glass batch to pass from the side inlet, through the inner tubular chopper, and through the outlet when the inner tubular chopper is in either of the first or second positions.
13. The device of claim 1 , wherein outer tubular housing has an outer wall that forms an interior void for circulating a coolant.
14. The device of claim 13 , wherein the outer tubular housing has an outlet for passing glass batch into a melter, and wherein the interior void is adjacent to the outlet.
15. A method of using a glass melter batch inlet and cleaning device, the method comprising:
passing glass batch through the glass melter batch inlet and cleaning device having an outer tubular housing with a side inlet and an inner tubular chopper including a side inlet relief in registration with the side inlet, the outer tubular housing also having an outlet for the glass batch; and
actuating the inner tubular chopper from a first position in which a chopping end of the inner tubular chopper is maintained in the outer tubular housing to a second position in which the chopping end extends out of the outer tubular housing and through the outlet.
16. The method of claim 15 , further comprising accessing an interior of the device through a side cleanout port in the outer tubular housing.
17. The method of claim 16 , wherein the step of accessing an interior includes taking a sample of the glass batch through the side cleanout port.
18. The method of claim 15 , wherein the step of actuating the inner tubular chopper includes pulling the inner tubular chopper from the first position to the second position.
19. The method of claim 15 , wherein the step of actuating the inner tubular chopper includes actuating the inner tubular chopper when glass solidifies at the outlet in order to clear the solidified glass from the outlet.
20. The method of claim 15 , wherein the step of passing glass batch includes horizontally passing the glass batch through the side inlet.
21. The method of claim 20 , wherein the step of passing glass batch includes vertically passing the glass batch through the outlet.
