Description
(1) technical field
The invention belongs to coating, drying and solidify technical field of heating, be specifically related to a kind of coating, drying that hangs conveying workpieces and solidify the forced convertion heating furnace, particularly relate to coating, drying a kind of energy savings, that hang conveying workpieces and solidify the forced convertion heating furnace.
(2) background technology
Most coating all need to place heating furnace to heat workpiece after installing on the workpiece being coated with, so that coating drying or levelling, curing, and the coating, drying solidifying heating furnice that is arranged on the finishing line generally all is to hang conveying workpieces, suspension conveyor system generally all is installed in the heating furnace, workpiece after the application is suspended on by hanger and carries on the balladeur train, and delivery track heats while advancing in the drive lower edge of chain.Because carry balladeur train and chain all will together heat in company with workpiece, the energy consumption of this heating furnace is higher.
Application number is that 97212288 Chinese patent discloses a kind of high IR continous way all-radiant furnace, its Work transfer device is installed in the heating furnace top, the two ends of heating furnace and entire top all are to open wide fully, be provided with highdensity electric heating infrared radiating element in the heating furnace, though this heating furnace conveying device does not heat together in company with workpiece, but because two ends and furnace roof open wide, the free convection heat loss is very serious, and can only adopt the radiation heating mode.
(3) summary of the invention
The objective of the invention is to: provide a kind of coating, drying that hangs conveying workpieces to solidify the forced convertion heating furnace, with existing technology ratio, this heating furnace is more saved heating energy source.
The solution of the present invention is: the coating, drying of a kind of energy savings, suspension conveying workpieces solidifies the forced convertion heating furnace, mainly comprise heating furnace and suspension conveyor system, heating furnace mainly comprises forced convection device, furnace sidewall and furnace roof wall, suspension conveyor system mainly comprises carrier chain, suspension conveyor system is positioned at the outside of heating furnace top, heating furnace, the continuous open seam that is positioned at below the carrier chain is being arranged on the furnace roof wall of heating furnace, and this continuous open seam is parallel to or the approximate carrier chain that is parallel to.Because suspension conveyor system is positioned at the outside of heating furnace, do not heat together in company with workpiece, thereby energy consumption is lower, though have on the furnace roof wall, be provided with continuous open seam outside the heating furnace owing to suspension conveyor system is placed, but because the width of open seam is very little, the heat energy that runs off by open seam also seldom, thereby with existing technology ratio, the present invention more saves heating energy source.
Major advantage of the present invention has two: one is to save heating energy source, and another is owing to adopt the forced convertion mode of heating, is applicable to various heating energy source.
In order further to reduce heat by continuous open seam convection losses, the one or both sides of open seam can also be provided with the open seam masking device continuously, this open seam masking device can be movable, the pipe that fills cooling water and made by flexible waterproof material in can being.
Reduce heat by continuous open seam convection losses again in order to satisfy needs that hanger passes through, the width of continuous open seam is preferably less than 50mm as far as possible.
In order to be applicable to the fuel heating, the forced convection device in the heating furnace can comprise air-supply arrangement and air-returning device.
In order to make the forced convertion direction consistent with the free convection direction, air-supply arrangement preferably is positioned at the top of heating furnace, and air-returning device preferably is positioned at the bottom of heating furnace.
For the hot blast in the heating furnace can not scattered and not disappeared outside stove by continuous open seam, air-returning device preferably is positioned at the one or both sides of continuous open seam.
Forced convection device in the heating furnace can also mainly comprise the forced convertion fan, and the forced convertion fan preferably is positioned at the top of heating furnace.
