Description

DESCRIPTION
DETACHABLE BIN FOR MODULAR CLEANER SYSTEM FOR AIRBORNE DUST
Technical Field
In one aspect this invention relates to a collector for airborne dust that is assembled from modular components and has a detachable collected-dust bin. In other aspects, this invention relates to collecting airborne dust on an industrial scale with a detachable, removable and exchangeable collected-dust bin.
Background Art
The disclosure of my PCT patent application, PCT/US 16/34138, filed 25 May 2016, published as WO 2016/191484 on 1 December 2016 is incorporated herein by reference.
There is a growing need for removing dusty air from industrial, work, maintenance or production facilities and cleansing it of entrained dust prior to discharge.
Traditionally, for dust producing facilities operating airborne dust collection systems, fixed dust collection equipment is permanently installed with dedicated collected-dust removal techniques. For any dust collecting system, whether fixed or portable, if the collected dust is considered hazardous, the removal and handling of the collected dust from standard dusty air cleaners can be a challenge requiring special precautions. Difficulties in the handling and decanting of collected dust waste included the risk of spillage, special handling of dust collection bags if used, and special transportation procedures once the collected dust is removed from the original dust collecting system.
It is an object of this invention to provide a cleaning device for airborne dust that is large in air volume cleaning capacity and is inexpensive to manufacture and service because of its modular construction. My PCT application referenced above incorporates a removable bin of the type used commonly by waste handing companies, also referred to as dumpsters for collecting the dust. For some applications, however, a smaller collection device would be desirable, and the purpose of this disclosure is to provide two such devices.
Disclosure of Invention
In one embodiment of the invention, an apparatus comprises an aperture plate, a plurality of tubular filters, a dirty gas distributor, four side walls depending from the dirty gas distributor, and a detachable end closure depending from the four side walls. The aperture plate defines a plurality of apertures. The plurality of tubular filters hangs from the apertures, one per aperture. The dirty gas distributor is positioned to distribute dirty gas from a peripheral location with respect to the filters. The dirty gas distributor comprises a pair of parallel tubular sidewalls forming a pair of tunnels spaced apart from each other. The four side walls are attached to the dirty gas distributor and extend in a direction away from the aperture plate and peripherally to the plurality of tubular filters to form a box having a height sufficient to contain the tubular filters. The detachable end closure is positioned on the box opposite the aperture plate to form a dust collection chamber for collected dust.

Best Mode for Carrying out the Invention
The various illustrated embodiments of the invention have certain common elements. They comprise an aperture plate 4, a plurality of tubular filters 6, a dirty gas distributor 8, and four side walls 10 depending from the dirty gas distributor. Two types of detachable end closures, 2 (see Figures 1-3) or 2', (see Figures 4-10) depend from the four side walls.
The aperture plate defines a plurality of apertures. The plurality of tubular filters hangs from the apertures, one per aperture. The dirty gas distributor is positioned to distribute dirty gas from a peripheral location with respect to the filters. The dirty gas distributor comprises a pair of parallel tubular sidewalls forming a pair of tunnels 3, 5 spaced apart from each other. Ports 7 open through the sidewalls between the rows of filters. The four side walls are attached to the dirty gas distributor and extend in a direction away from the aperture plate and peripherally to the plurality of tubular filters to form a box having a height sufficient to contain the tubular filters. The detachable end closure is positioned on the box opposite the aperture plate to form a dust collection chamber 12, 12' for collected dust.
In my PCT patent application, PCT/US16/34138, most embodiments utilized a dumpster to both support the dirty air distributor and as a dust collection chamber. Preferably in the embodiments disclosed herein, a frame 14, 14' supports the dirty gas distributor to suspend the detachable end closure above ground level.
For use, a roof 16 is positioned above the aperture plate. A clean-gas chamber 18 is defined between the at least one aperture plate and the roof. The clean-gas chamber is partly defined by a peripheral wall extending between the at least one aperture plate and the roof. A pulse-jet assembly 20 is positioned at least partly in the clean-gas chamber. The pulse-jet assembly includes a plurality of nozzles for pulsing jets of gas down the plurality of filters, one nozzle per filter. A blower 22 (Figure 10) is in flow communication with the clean gas chamber to draw dirty gas into the dirty gas distributor, through the filters, and through the clean gas chamber. In the devices shown, unneeded ports can be covered by blowout plates 24. To adapt the dirty gas distributors shown in Figures 2 and 5 for use, some of cover/blowout plates 24 are replaced by nozzles 26 as shown in Figures 3 and 6 for attachment to ducts drawing from the volume needing dust control.
In the apparatus shown in Figures 1-3, the end closure is formed as a detachable, nestable, sump 28. The sump is preferably box-shaped. It can be formed from sheet metal, a resinous material such as FRP or corrugated plastic, for example, or a cellulosic material such as cardboard. The sump preferably has a rectangular cross section in the horizontal plane, an upper end, and a lower end, and the cross section is larger in area at the upper end than at the lower end to provide for nesting. In the illustrated embodiment, the sump has an outwardly extending flange 30 at the upper end that matches a flange 32 (See Figure 3) at a lower end of the four side walls attached to the dirty gas distributor and it is attached by its flange to the flange at the lower end of the four side walls.
In the apparatus shown in Figures 4-9, the detachable end closure is formed as a detachable at least one hopper bottom 34. Each detachable hopper bottom has an upper end and a lower end and comprises four interconnected walls having flat central sections 36 sloping downwardly from the upper end to meet with a tubular outlet 38 at the lower end. In the illustrated embodiment, the flat central sections are generally triangularly shaped. Each hopper bottom has an outwardly extending generally rectangular flange 40 at the upper end that at least partly matches a flange 42 at a lower end of the four side walls attached to the dirty gas distributor and the hopper bottom is attached to the dirty gas distributor flange to flange. See Figure 6. If desired, a lid 44 seals the tubular outlet. If desired, a bag (not shown) can be positioned above the lid so that removal of the lid dumps the hopper contents into the bag. The bag is attached to the mouth of the tubular outlet and is positioned in the hopper. In another embodiment, a bag 46 seals the tubular outlet. See Figure 8. In another embodiment, a drum 48 seals the tubular outlet. See Figure 7. Optionally, a tubular chute (not shown), can connect the tubular outlet to a mouth of the drum. In another embodiment, a bag 50 is connected to the tubular outlet and lines the drum.
While certain preferred embodiments of the invention have been described herein, the invention is not to be construed as being so limited, except to the extent that such limitations are found in the claims.
