Description

FUME EXTRACTION APPARATUS AND METHODS FOR EXTRACTING FUMES ASSOCIATED WITH ROLL COATING MACHINES
Field of the Invention
The present invention relates generally to fume extraction apparatus and methods of extracting fumes. The invention may be particularly useful when applied to roll coating machines. The invention also relates generally to roll coating machines themselves having associated fume extraction apparatus mounted thereto.
Background to the Invention
Many kinds of coatings and cleaning fluids for removing coatings emit hazardous fumes. Roll coating machines, which apply the coatings and to which the coating removers are routinely applied, are thus generally disposed in a dedicated room which is usually ventilated by changing all of the air in the coater room at a rate of approximately 60 - 120 complete air changes per hour. This air must generally be incinerated.
This ventilation is generally achieved by a combination of bulk cross-room air flow entering from one wall and exhausting from an opposite wall.
Existing ventilation arrangements tend to draw more fumes than is necessary from adjacent coating reservoir surfaces or coated surfaces because they draw air off the reservoirs or coating surfaces at a high rate, which wastes resources in drawing unnecessary fumes out of the room, and then wastes further resources in burning the unnecessary fumes.
The present invention seeks to ameliorate one or more of the above-mentioned disadvantages. Summary of the Invention
According to one aspect of the present invention there is provided a fume extraction apparatus suitable for use with a roll coating machine for coating one or more sides of a passing coil or strip or web, the fume extraction apparatus including: one or more fume extraction heads for receiving fumes, each of the one or more fume extraction heads being configured to be in fluid communication with a respective duct or duct assembly, the or each duct or duct assembly being configured when in use to direct the fumes towards an interior position within the roll coating apparatus.

Description of a Preferred Embodiment
Referring to the Figures there is shown a roll coating apparatus generally indicated at 10, the roll coating apparatus 10 including a coil handling apparatus 12 and two roll coating heads 14 and 15. The roll coating heads include pick-up rolls 13 and applicator rolls 16 respectively for picking up the coating 7 from a tray 17 and applying it to a coil or web or sriplδ. In use, the coil or web or strip 18 is drawn through the roll coating apparatus 10 by the coil handling apparatus 12 which includes coil handling rolls 11 and 19.
The roll coating apparatus 10 may also include a roll cleaning apparatus (not shown) which may include solvents for cleaning any and all of the rolls.
The roll coating apparatus 10 is disposed within a roll coating room 5.
The coating 7 and solvents applied to the coil 18 emit fumes into the roll coating room 5. A fume extraction apparatus 20 is provided to extract the fumes from the room 5.
The fume extraction apparatus 20 includes two fume extraction heads 22 and 23, each one associated with respective coating heads 14 and 15 and each one disposed internally of the roll coating apparatus 10 so as to extract fumes from the coil and/or coating heads towards a position within the roll coating apparatus 10. The fume extraction heads 22 and 23 extend to a width of the roll coating heads so as to facilitate the extraction of fumes from the entire width of the roll coating heads.
The fume extraction heads 22, 23 are configured to operatively connect to a respective duct 40 for fluid communication between the duct 40 and the fume extraction heads 22, 23. A duct connection apparatus 32 is provided to operatively connect the respective duct 40 to the fume extraction head 22, 23. The fume extraction heads 22 and 23 include a plurality of air intake openings 24 for drawing fumes from adjacent areas. Each air intake openings 24 includes a gather or nacelle 26 for facilitating an evenly distributed, low velocity and low turbulence air draw from the adjacent fume areas. The gather or nacelle 26 includes walls 28 which are generally inwardly directed, and which are in the form of a straight taper 29 so as to reduce manufacturing costs. The walls 28 extend inwardly towards a wall end or wall focus region 27.
The fume extraction heads 22 and 23 are disposed vertically so as to facilitate the even and Io w- velocity drawing of air from the tray 17, roll 13, 16 and coil 18 surfaces. Filters 36 are provided so as to reduce particle contamination of the duct 40 and other parts of the fume extraction apparatus 20.
Fume extraction head 22 is disposed adjacent coating head 14 so as to draw fumes from the associated rolls 13, 16 and tray 17 in that area, and similarly, extraction head 23 is disposed adjacent coating head 15.
An intake or plenum chamber 30 is disposed adjacent the wall end or wall focus region 27 so as to direct extracted air and fumes towards the respective duct 40.
Each duct 40 extends, from the duct connection apparatus 32, past the edges of the roll coating apparatus 10 and through a wall aperture 3 to a point outside the room 5. A fan or blower (not shown) is provided to draw the fumes into the fume extraction heads 22, 23, an impeller wheel being disposed adjacent or in the duct 40.
An incinerator (not shown) is provided to incinerate fumes or contaminants.
In operation the coil 18 passes through the coil handling apparatus 12 in the direction shown by arrows 50. Coil coating heads 14 and 15 are moved into a coating position where applicator rolls 16 abut coil 18. The pick up rolls 13 pick up the coating 7 from the tray 17, transfer it to applicator rolls 16 which in turn transfer the coating 7 to their respective side of the passing coil 18.
The blower draws air along duct 40 in the direction indicated by the arrows 44. Air is drawn from areas adjacent the fume extraction heads 22 and 23 at a much lower, more laminar and more uniform velocity due to the gather or nacelle 26 which gradually opens up the volume accessed by the ductwork by the tapered walls 28.
Advantageously, the preferred embodiments of the present invention reduce the amount of air required to be incinerated by reducing wasteful and unnecessary fume draw from the surface of the coating 7 in the tray 17 and from other surfaces, as well as reducing wasteful movement and incineration of air which has little or no contaminants. Air volumes required for safe ventilation may be reduced by up to 90%. Also, incinerant gases may be reduced by similar amounts.
Other embodiments of extraction heads are shown in FIGS 4-10, wherein the air intake openings 124 are on the front and back walls.
