Abstract
Abstract A disintegrator comprising a housing accommodating rotors with bladed wheels (5), and electric motors (3), a housing of each electric motor (3) having two flanges (7 and 8) of which one flange (7) is rigidly connected to the front portion of the housing of the electric motor (3) and to movable or stationary station (2 or 1) of the housing of the disintegrator, whereas the second flange (8) is secured on a support (9). One of the electric motors with the movable section (2) of the housing is capable of movement under the action exerted thereon by a screw mechanism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
332 words
A disintegrator comprising: a housing having a moveable section and a stationary section; a first electric motor connected with said moveable section and having a first rotatable shaft; a second electric motor connected with said stationary section and having a second rotatable shaft; a first set of rotors mounted on said first rotatable shaft for rotation in a first direction and having a first set of bladed wheels; a second set of rotors mounted on said second rotatable shaft for rotation in a second direction opposite to said first direction having a second set of bladed wheels; support means for supporting the first and second electric motors; first fixed coupling flanges fixed to said moveable section and said stationary section at first ends of said electric motors, respectively; second fixed coupling flanges resting on said support means and located at second, opposite ends of said electric motors, respectively; displacement means for displacing said moveable section and said first electric motor with respect to said stationary section and for absorbing axial forces generated between the moveable and stationary sections, said displacement means including means for causing said moveable section and said first electric motor to move with respect to said support means and including guides, a plurality of screw mechanisms spaced along the circumference of the housing for moving the moveable section and first electric motor with respect to the stationary section with the aid of the guides, and drive means for simultaneously driving said screw mechanisms uniformly to cause said moveable section and said first electric motor to move with respect to said stationary section; and first and second centering element means mounted on the moveable section and stationary section, respectively, for aligning the moveable section and stationary section when said moveable section and stationary section are locked together and for absorbing radial forces between the moveable and stationary sections, said first and second centering element means being engaged with each other when said moveable section and stationary section are locked together.
Claim 2
Dependent Claim
332 words
A disintegrator comprising: a housing having a moveable section and a stationary section; a first electric motor connected with said moveable section and having a first rotatable shaft; a second electric motor connected with said stationary section and having a second rotatable shaft; a first set of rotors mounted on said first rotatable shaft for rotation in a first direction and having a first set of bladed wheels; a second set of rotors mounted on said second rotatable shaft for rotation in a second direction opposite to said first direction having a second set of bladed wheels; support means for supporting the first and second electric motors; first fixed coupling flanges fixed to said moveable section and said stationary section at first ends of said electric motors, respectively; second fixed coupling flanges resting on said support means and located at second, opposite ends of said electric motors, respectively; displacement means for displacing said moveable section and said first electric motor with respect to said stationary section and for absorbing axial forces generated between the moveable and stationary sections, said displacement means including means for causing said moveable section and said first electric motor to move with respect to said support means and including guides, a plurality of screw mechanisms spaced along the circumference of the housing for moving the moveable section and first electric motor with respect to the stationary section with the aid of the guides, and drive means for simultaneously driving said screw mechanisms uniformly to cause said moveable section and said first electric motor to move with respect to said stationary section; and first and second centering element means mounted on the moveable section and stationary section, respectively, for aligning the moveable section and stationary section when said moveable section and stationary section are locked together and for absorbing radial forces between the moveable and stationary sections, said first and second centering element means being engaged with each other when said moveable section and stationary section are locked together.
Claim 3
Dependent Claim
62 words
A disintegrator according to claim 1; further including a shock absorbing base on which said movable section and said stationary section of said housing and said electric motors are mounted; and wherein each screw mechanism includes a fixed element connected to said shock absorbing base and a movable element screw-threadedly connected with said fixed element adjacent the movable section of the housing.
Claim 4
Dependent Claim
74 words
A disintegrator according to claim 2; wherein each fixed element is connected to the stationary section of the housing and each movable element is connected with the first electric motor adjacent the movable section of the housing, each screw mechanism further including a sprocket secured at an end of each respective movable element; and said drive means includes a common chain extending around the sprockets and one of the sprockets constituting a drive sprocket.
Claim 5
Dependent Claim
123 words
A disintegrator according to claim 3; further including a first casing connected to at least one of the flanges and rigidly attached to the movable section of the housing and accommodating the first electric motor therein; a second casing connected to at least one of the flanges associated with the second electric motor and rigidly attached to the stationary section of the housing for accommodating the second electric motor therein; the first and second casings and the housing being mounted on a shock absorbing frame; said screw mechanisms being connected to said first casing; and further including guides for guiding said electric motors in said respective casings and roller supports for slidably moving said electric motors along said guides in said respective casings.
Claim 6
Dependent Claim
41 words
A disintegrator according to claim 4; wherein each of said casings includes a cover having an inlet tube and said first and second flanges have holes therein to conduct a gas admitted through the inlet tubes for cooling the electric motors.
Claim 7
Dependent Claim
35 words
A disintegrator according to claim 1; wherein said first and second flanges, said movable section and said stationary section are provided with through holes which receive studs to form a rigid and structurally integrated disintegrator.
Claim 8
Dependent Claim
81 words
A disintegrator according to claim 1; wherein said housing has disks therein which form, with sides of said housing, chambers communicating at one side thereof with ambiant atmosphere through holes 44 provided in said housing, and at an opposite side of said chambers through clearances between the disks and a central hub with a chamber in which the rotors are located, and further including adjustable valves provided in said holes in the housing through which the chambers communicate with ambiant atmosphere.
