Adjustable diverter or flow controller for a flow apparatus
The present invention provides a diverter or flow controller 1.060, 26.060 for controlling a flow on or within an apparatus 1.001, 26.500 , including at least one diverter or flow controller element 1.065, 26.2 and one or more displacement members 1.064, 26.064 adapted to move at least part of the diverter or flow controller element 1.065, 26.2 or a corresponding one of the diverter or flow controller element 1.065, 26.2 into or out of contact with a flow path. The invention also provides a remotely controlled diverter or flow controller and is applicable to flow devices or apparatus such as spiral concentrators and banks of these as up-current classifiers, hydraulic classifiers, teeter bed style classifiers, sluices, weirs, or channels.
1. A diverter or flow controller for controlling a flow on or within an apparatus, including
at least one diverter or flow controller element and
a plurality of displacement members adapted to move at least part of said diverter or flow controller element into or out of contact with a flow path, wherein each of said plurality of displacement members comprises an expandible bladder and said expandible bladder is individually inflatable or deflatable, and
a plurality of actuators, each of which actuates a different one of said plurality of displacement members.
2. A diverter or flow controller as claimed in claim 1 , including attachment means to attach the diverter or flow controller to the apparatus or a trough assembly of the apparatus.
3. A diverter or flow controller as claimed in claim 1 , wherein said diverter or flow controller includes mounting means to connect to a mounting bracket, said mounting bracket adapted to be mounted to said apparatus.
4. A diverter or flow controller as claimed in claim 1 , wherein said diverter or flow controller includes a housing to cover one or more of said plurality of said displacement members.
5. A diverter or flow controller as claimed in claim 1 , wherein said plurality of displacement members move into or out of contact with said flow path by extension or retraction of said displacement members toward or from an inner surface of said trough assembly of the apparatus.
6. The diverter or flow controller as claimed in claim 1 , wherein said inflatable bladder is a bellows or bellows formation formed by a portion of a wall being formed at moulding with a wall portion that folds back over itself through approximately 180 degrees.
7. The diverter or flow controller as claimed in claim 1 , wherein said wall portion that folds back over itself comprises a bend with elasticity sufficient to provide a retraction basis.
8. The diverter or flow controller as claimed in claim 1 , wherein at least a portion of said inflatable bladder comprises a material with at least one property selected from the group consisting of elasticity, shape memory, material memory and rigidity.
