摘要：An apparatus for separating fibrous material such as wool, wood, paper, cellulose, rockwool, fiberglass, etc., which is conveyed by and suspended in air. The separator can be used with pneumatic vacuum systems and pneumatic pressure conveying systems for separating fibrous material used for insulation. The apparatus includes a housing having an inlet, an air outlet and a fibers outlet. An air lock is provided at the fibers outlet for allowing fibrous material to exit but generally restricting the air from exiting therethrough. A screen supported on a support fixture located at the air outlet allows air to pass but generally restricts fibrous material from exiting. The fibrous material is allowed to accumulate on the screen thereby forming a fibrous filter mat for filtering smaller fibrous particles. Scalping blades travel over and at a distance from the screen thereby removing accumulated fibrous material and retaining the fibrous filter mat at a desired thickness for allowing air to pass but filtering smaller fibrous particles. The distance between the screen and scalping blades is selectively adjustable by selectively moving the screen for thereby selectively adjusting the thickness of the filter mat. A pressure transducer senses the differential pressure between the housing and the air outlet and increases the thickness of the filter mat in response to decreasing pressure differential and decreases the thickness of the filter mat in response to increasing differential pressure.
