Separator assembly

Claim 2

A separator assembly for an air intake duct of a turbine device for normally removing particulate matter entrained in air being introduced into said turbine device, said air being introduced to flow through said air duct in a first direction, said separtator assembly comprising: separating means for removing particulate matter entrained in air passing therethrough; frame means for supporting said separating means; pivotal mounting means for pivotably mounting said frame means in said air duct so as to pivot about an axis extending in a second direction which is transverse to said first direction, and so that said frame means when mounted in said air duct is pivotably movable between a first position in which said separating means is arranged in said air duct so that substantially all of the air passing through said air duct passes through said separating means, and a second position in which said separating means is arranged so that air passing through said air duct bypasses said separating means; sensing means for sensing the pressure differential of the air across said separating means; and clamping means for normally clamping said frame means in said first position when said frame means is mounted in said air duct, said clamping means being operatively connected to said sensing means so that said clamping means is responsive to said sensing means sensing a pressure differential greater than a predetermined pressure difference to release said frame means from said first position so that the air flowing into said air duct causes said frame means to pivot about said axis toward said second position, whereby air flow will be maintained to the turbine device.

Claim 3

The separator assembly of claim 1 wherein said pivotal mounting means mounts said frame means so that when said frame means is in said first position said separting means is arranged to be substantially normal to said first direction at the location of said separating means, and so that when said frame means is in said second position said separating means is inclined with respect to the position of said separating means when said frame means is in said first position.

Claim 4

The separator assembly of claim 2 wherein said frame means has a peripheral outer portion surrounding said separating means and wherein said pivotal mounting means is adapted to mount said frame means adjacent an inlet opening of said duct so that when said frame means is in said first position, the outer peripheral portion of said frame means substantially encloses said inlet opening of said air duct so that substantially all of the air being introduced into said air duct passes through said separating means, and so that when said frame means is in said second position, at least a part of said frame means is displaced from said inlet opening to allow air being introduced into said air duct to bypass said separating means.

Claim 5

The separator assembly of claim 3 wherein said pivot mounting means comprises a pair of pin means disposed on opposite sides of said frame means and in alignment with one another for mounting said frame means for pivotable movement about an axis extending between said pair of pin means.

Claim 6

The separator assembly of claim 3 wherein said pivotal mounting means comprises hinge means for supporting a section of said frame means in said air duct for pivotal movement about said hinge means.

Claim 7

The separator assembly of claim 1 wherein said separating means comprises first and second separating stages, wherein said frame means supports said first and second separating stages in tandem arrangement to one another, and wherein said mounting means is adapted to mount said frame means so that said first and second separating stages are movable as a unit in said air duct.

Claim 8

A separator assembly for an air intake duct of a turbine device for normally removing particulate matter entrained in air being introduced into said turbine device, said air being introduced to flow through said air duct in a first direction, said separator assembly comprising: a first separating stage for removing particulate matter entrained in air passing therethrough; first stage mounting means for fixedly mounting said first separator stage in said air duct so that substantially all of the air passing through said air duct passes through said first separating stage; a second separating stage for removing particulate matter entrained in air passing therethrough; frame means for supporting said second separator stage; second stage mounting means for pivotably mounting said frame means in said air duct so as to pivot about an axis extending in a second direction which is transverse to said first direction, and so that said frame means when mounted in said air duct is pivotably movable between a first position in which said second separating stage is arranged in said air duct so that substantially all of the air passing through said air duct passes through said second separating stage, and a second position in which said second separating stage is arranged so that air passing through said air duct bypasses said second separating stage; sensing means for sensing the pressure differential of the air across at least one of said first and second separating stages; and clamping means for normally clamping said frame means in said first position when said frame means is mounted in said air duct, said clamping means being operatively connected to said sensing means so that said clamping means is responsive to said sensing means sensing a pressure differential greater than a predetermined pressure difference to release said frame means from said first position so that the air flowing through said air duct causes said frame means to pivot about said axis towards said second position, whereby air flow will be maintained to the turbine device.

Claim 9

A separator assembly for an air intake duct of a turbine device for normally removing particulate matter entrained in air being introduced into said turbine device, said air being introduced to flow through said air duct in a first direction, said separator assembly comprising: a first separating stage for removing particulate matter entrained in air passing therethrough; first stage mounting means for fixedly mounting said first separator stage in said air duct so that substantially all of the air passing through said air duct passes through said first separating stage; a second separating stage for removing particulate matter entrained in air passing therethrough; frame means for supporting said second separator stage; second stage mounting means for pivotably mounting said frame means in said air duct so as to pivot about an axis extending in a second direction which is transverse to said first direction, and so that said frame means when mounted in said air duct is pivotably movable between a first position in which said second separating stage is arranged in said air duct so that substantially all of the air passing through said air duct passes through said second separating stage, and a second position in which said second separating stage is arranged so that air passing through said air duct bypasses said second separating stage; sensing means for sensing the pressure differential of the air across at least one of said first and second separating stages; and clamping means for normally clamping said frame means in said first position when said frame means is mounted in said air duct, said clamping means being operatively connected to said sensing means so that said clamping means is responsive to said sensing means sensing a pressure differential greater than a predetermined pressure difference to release said frame means from said first position so that the air flowing through said air duct causes said frame means to pivot about said axis towards said second position, whereby air flow will be maintained to the turbine device.

Claim 10

The separator assembly of claim 7 wherein said second stage mounting means comprises hinge means for hingedly supporting said second separating stage on said first separating stage so that said first and second separating stages are arranged in tandem to one another when mounted in said air duct when said frame means is in said first position, and so that said second separating stage is inclined relative to said first separating stage when said frame means is in said second position to allow air passing through said first separating stage to bypass said second separating stage, and wherein said clamping means is actuable to release said second separating stage for movement relative to said first separating stage in response to said sensing means sensing a pressure differential above said predetermined pressure difference whereby the air flow through said air duct will pivot said second separating stage relative to said first separating stage to allow air to bypass said second separating stage.
