Abstract
A system for drying a battery plate grid is disclosed. The system includes a pair of heated rollers disposed adjacent to one another, and a conveyor belt arranged to transfer the battery plate grids toward the heated rollers, such that the battery plate grid passes between, and comes in contact with, each of the heated rollers. The system includes a convection oven arranged to circulate convection heat around the battery plate grid when the battery plate grid completes transfer through the heated rollers.
Claims20
A system for drying a battery plate grid, the system comprising:
- a heated rollers portion directly connected to a convection oven portion, the heated rollers portion comprising:
- at least one pair of heated rollers disposed adjacent to one another and spaced apart to define a passage therebetween;
- and
- a first conveyor belt arranged upstream from the heated rollers and a first portion of a second conveyor belt arranged downstream from the heated rollers, wherein the heated rollers are configured to receive the battery plate grid from the first conveyor belt and movably transfer the battery plate grid, via the passage, to the second conveyor belt, and wherein the heated rollers are disposed to interfere with a surface of a paste applied to a surface of the battery plate grid to remove moisture from the surface of the paste;
- and
- the convection oven portion comprising a convection oven configured to house a second portion of the second conveyor belt, wherein the second conveyor belt is arranged to movably transfer the battery plate grid from the outlet of the heated rollers portion to an inlet of the convection oven and along a length of the convection oven toward an outlet of the convection oven, and wherein the convection oven is configured to apply convection heat to the surface of the paste on the battery plate grid to remove moisture from the surface of the paste.
A method for drying a battery plate grid, the method comprising:
- movably transferring, using a first conveyor belt, the battery plate grid toward at least one pair of heated rollers arranged adjacent to one another and spaced apart to define a passage therebetween, wherein a surface of the battery plate grid includes a paste applied to two sides of the battery plate grid, and wherein the two sides oppose one another;
- movably transferring the battery plate grid, via the passage, to a second conveyor belt, wherein each of the heated rollers is disposed to interfere with a surface of the paste of the battery plate grid to remove moisture from the surface of the paste;
- movably transferring, using the second conveyor belt, the battery plate grid to a convection oven directly connected to a portion that houses the heated rollers;
- and
- movably transferring, using the second conveyor belt, the battery plate grid from an inlet of the convection oven and along a length of the convection oven toward the outlet of the convection oven to expose the surface of the paste to convection heat to remove moisture from the surface of the paste.
A system for drying a battery plate grid, the system comprising:
- a housing comprising:
- a first conveyor belt,
- a second conveyor belt spaced apart from the first conveyor belt,
- a pair of heated rollers disposed between the first and second conveyor belts, wherein the heated rollers are configured to receive the battery plate grid from the first conveyor belt and movably transfer the battery plate grid to the second conveyor belt, wherein the heated rollers are disposed to come in contact with a surface of paste applied to two opposing sides of the battery plate grid to remove moisture from the surface of the paste, and
- a convection air circulating device configured to, while the second conveyor belt movably transfers the pasted battery plate grid through interior of the housing, circulate air over the surface of the paste to remove moisture therefrom.
