Description
SPECIFICATION
Fluidised Bed Apparatus
This invention relates to a fluidised bed apparatus, particularly but not exclusively a fluidised bed dryer.
Fluidised bed dryers are known wherein a forced draught of heater air is used to fluidised particulate material to be dried, the material being received in a container releasably situated above a diffuser and below a fluidisation chamber into which particles rise, suspended by the air draught, during drying.
It is a disadvantage of such known dryers that particulate material, especially undersize material, may fall down into the diffuser and other parts of the apparatus directly beneath the material container, through the mesh support separating the material container from the diffuser so that when the apparatus is to be supplied with a charge of new material, the container only is removed, filled and replaced. Thus when the drying is recommenced the particulate material in the diffuser is carried upwards and may mix with the new charge, thereby contaminating it.
The mesh support separating the diffuser and material container is generally supported on a perforated plate, the combination being received at their edges in a groove and resting on a clamping device. The plate is generally secured for operation by inserting a segment into the circumference of the clamping device, so enlarging the circumference so that the clamping device is pushed against the walls of the groove in a gripping relationship. This has the disadvantage that the seal may be impaired by material trapped in the groove and such material may be a contaminant to subsequent batches.
An agitator is sometimes provided in known dryers in the material container and this usually comprises one or more rotors, driven internally or externally of the chamber, the rotors being immersed in the fluidised particulate material.
Such agitation is used to prevent loss of efficiency through air channeling. Such agitation requires relatively large amounts of energy, at start-up especially, and because the rotors are wholly immersed in material they are prone to breakdown.
The present invention provides a fluidised bed apparatus having a module comprising a material container, mesh support means for supporting material in the container and those portions of the apparatus which lie directly beneath the mesh support means and into which it is possible for material to fall through said mesh support and means for releasably securing said module to the apparatus.
Where the material container connects with the appartus, particularly an expansion chamber, preferably a substantially fluid tight seal is provided.
The module may be removed for cleaning and may have wheels or castors for ease of movement.
Preferably the module includes a diffuser through which fluid for the fluidisation passes in operation of the apparatus. Where the fluidised bed apparatus is a dryer, heater means may be provided to heat the fluid, typically air. Preferably, where the material container joins the expansion chamber, clamping means are provided for releasably clamping the material container to the expansion chamber with electrical conduction therebetween. Said clamping means preferably comprises a band, in use overlapping abutting rim portions of the material container and of the expansion container, said band having securement means for reducing the circumference of said band to clamp it to said rim portions, the band being electrically conductive.
Desirably the band has a pair of opposed free ends which, in a release condition, are spaced from one another, the securement means being operable to move the free ends towards one another to achieve the clamping action. The securement means may comprise a screw with a tightening nut such as a wing nut; a solenoid; a fluid ram or any other convenient fastening. The band may be in two or more parts connectible or connected by hinges and or a plurality of said securement means.
At an opposite end of said module, for example in a preferred embodiment where the diffuser meets an inlet chamber for fluidising medium the means for releasably securing said module to the apparatus may comprise co-operating flange portions with or without clamping means. At this end of the apparatus securement is not generally a problem since the influx of fluid into the module will tend to maintain a connection between the diffuser and the fluid inlet chamber.
The invention further provides a mesh support arrangement for a fluidised bed apparatus comprising a perforated support plate having an unperforated peripheral stiffening portion, a mesh overlying said support plate, means for releasably clamping the mesh to the support plate and means for releasably securing the mesh support arrangement in sealing engagement between the material container and an adjacent part of the fluidised bed apparatus.
Said adjacent part is preferably the diffuser.
The peripheral stiffening portion is preferably a ring of "L" section, the mesh overlying the support plate with the periphery of the mesh overlying said "L" section.
The means for releasably clamping the mesh preferably comprises a clamping ring of square or rectangular cross-section securable to the "L" section by screws, or other fixing means, clamping the mesh between itself and the "L" section.
Desirably an "0" ring seal is provided on an upper surface of said clamping ring for sealing engagement with a sealing flange of the material container. Preferably the mesh support apparatus is clamped in sealing engagement between flanges provided respectively on the material container and on the diffuser.
The invention also provides agitation apparatus for a fluidised bed apparatus comprising one or more agitation members, means for lowering the or each said agitation member into a mass of material in the fluidised bed, means for moving the or each agitation member to agitate said material.
The agitation apparatus preferably comprises an axially movable rotatable shaft having at its lower free end at least two arms each mounting at least one downwardly extending finger which provides the agitation members. The fingers are progressively lowered into the fluidised bed whilst the shaft rotates in one or more directions to agitate the said material.
Vibratory means may be attached to the apparatus as set forth in any of the preceding paragraphs to aid in the agitation of the fluidised bed. Preferably the fluidising medium is drawn through the apparatus by a suction fan and desirably means are provided for cleaning the filter elements present in the apparatus by means of reverse air flushing.
The invention additionally provides fluidised bed apparatus incorporating one or more of the features set out in the preceding paragraphs.
An embodiment of the invention will now be described by way of example only with reference to the accompanying drawings, in which: Fig. 1 is a schematic side elevation partly in cross section of apparatus according to the invention;
Fig. 2 is a part cross-sectional view of the clamping arrangement according to the invention for retaining material in the material container;
Fig. 3 is an end view of part of a clamping arrangement according to the invention;
Fig. 4 is a front elevation of the clamping arrangement shown in Fig. 3; and
Fig. 5 is a part front elevation of an alternative clamping arrangement to that shown in Figs. 3 and 4.
The apparatus shown in Fig. 1 comprises an air inlet chamber 10 having heating elements 12, therein, a diffuser 14, material container 16, expansion chamber 18, plenum chamber 20 and suction fan 22 powered by a motor 24. The material container 1 6 and the diffuser 14 constitute a module which is releasably secured to the expansion chamber 1 8 and abuts the chamber 10 at A. The module is mounted on wheels 26 permitting it to be moved from beneath the expansion chamber and the remainder of the apparatus for cleaning and recharging of the material container 1 6. The expansion chamber 18, plenum chamber 20 and the remainder of the apparatus above the material container 1 6 are supported by means not shown and do not rely for their support upon the said module.At A a flange of the diffuser 14 abuts a complementary flange of an inlet chamber 10, and unless toxic materials are being processed this abutment will suffice to ensure correct operation of the apparatus. Deformable rubber gaskets may be provided if desired. Where toxic materials are being processed a gasket may be provided together with one or more clamps to ensure a fluid-tight seal. The material container is provided with vibratory pads 28 to assist in obviating clogging of material in the container.
At B the material container 1 6 and expansion chamber 18 are open ended and abut one another, the two being clamped together for use of the apparatus by means of a clamping band 30 having a gap therein, the gap being closable by means of a screw 34 having a wing-nut 36 thereon, the tightening of the wing-nut 36 causing the band to be tightly clamped around a region where the expansion chamber 18 and the material container 1 6 abut so holding the two together in sealing engagement. A rubber or other deformable gasket may be provided between the surfaces of the material container 1 6 and the expansion chamber 1 8 to ensure a fluid-tight seal.
The clamp 30 is made from electrically conductive material so that static charges built up during fluidisation can leak through the apparatus wall to earth.
An alternative form of the clamping band 30 is shown in Fig. 3 and 4 and a further alternative is shown in Fig. 5.
The band 30 shown in Figs. 3 and .4 is substantially the same as that shown in Fig. 1, the screw 34 being movable about a pivot 40 to engage with a U shaped abutment 42 the shoulders of which the wing nut 36 beards upon when the nut is tightened.In the alternative form shown in Fig. 5 the band 30 is supported by a plurality of hydraulic rams 44 which are able to lower the band 30 into position over the abutment region of the expansion chamber 18 with the material container 1 6. When the band 30 is in position the gap 46 between the ends of the band 30 is closable by actuation of a hydraulic ram 48 one part of which is fixed to one free end of the band at an abutment 50 and connected at another part to the other free end of the band by means of rods 52, so that actuation of the hydraulic ram 48 causes the gap 46 to close, so clamping the band 30.
Returning now to Fig. 1 the connection between the diffuser 14 and the material container 1 6 although shown as a mere pair of abutting flanges at C in Fig. 1, is shown in detail in
Fig. 2. The diffuser has at its base a flange 19, a complementary flange 1 7 being provided at an upper part of the diffuser 14. Between the flanges 1 7, 1 9 is received the material support comprising a perforated plate 50 to which is welded around the periphery thereof a stiffening element 52 which in cross section is of "L" shape.
A fine mesh 56 overlies the perforated plate 50 and stiffening element 52. A lower part of the stiffening element 52 provides a flange upon which is seated an annular clamping block 58 which is of substantially rectangular radial cross section. The block 58 receives in a groove on an upper surface thereof an "0" ring seal 60 which abuts, in use, the flange 19. In use the material support is clamped between the flanges 1 7 and 19 in sealing engagement by means of clamps (not shown).
The expansion chamber 1 8 accommodates filter elements 62 which may be of the bag or cartridge type. The expansion chamber 1 8 also accommodates an agitator, only part of which is shown in Fig. 1, comprising a rod 64 having a plurality of arms 66 each having a downwardlyextending finger 68. The rod is lowerable in use, into the material container 16 and the rod 64 may be rotated by a motor external of the chamber 18 so that the fingers 68 agitate the material in the material container 16, the rod 64 and thus the fingers 68 being retracted if it is desired to remove the said module for cleaning and recharging. The plenum chamber 20 has an access hatch for maintenance and suction fan 22 is reversible to provide a reverse air draught for flush-cleaning the filter elements 62.
The apparatus may be made of any suitable material, for example plastics or metal and the metal may be coated with a protective material to guard against corrosion and/or contamination of products processed.
Various modifications may be made within the scope of the invention. For example the clamping band 30 shown in Figs. 1, 3,4 and 5 may be omitted and some other means of sealingly securing the material container and expansion chamber together substituted. Alternative agitating means instead of the rod 64 arm 66 and fingers 68 may be provided and the apparatus may be provided with a draught of air by blowing rather than suction.
In another modification the filter elements 62 can be cleaned one at a time or in groups by supplying to their exits in the reverse direction a constant flow or pulses of compressed air from.a remote compressed air source. By cleaning only a few of the elements the others can function normally so that the apparatus need not bé shut down.
