Abstract
A device and process for separating impurities from textile fibers during horizontal pneumatic transport is provided. The device includes a hollow parallelepiped separator of rectangular cross-section for the passage of transport fluids, such as air, therethrough. The passage section is subdivided into an upper part, for the cleaned fluid, and a lower part, for the separation of the impurities (i.e., foreign materials) in a hopper intercepted by an extractor having a seal. This subdivision is regulated by a deflector knife which induces an S-shaped motion of the transport fluid 4 and separates the impurities (i.e., foreign materials) by centrifugal force.
Claims9
A separating device for separating impurities from textile fibers in flake form during pneumatic transportation thereof, wherein said separating device is located between ducts connecting machines for processing the textile fibers, said separating device comprising:
- a hollow containment parallelepiped of rectangular cross-section having an upper wall which is stationary and a lower wall which is pivotable, wherein said rectangular cross-section of said hollow containment parallelepiped is consistent with a cross-section of said ducts connecting said machines to said hollow containment parallelepiped;
- a rack fulcrum-mounted at a fulcrum at said upper wall so as to be pivotable within said hollow containment parallelepiped;
- a passage section of said hollow containment parallelepiped having a variable area, wherein said variable area of said passage section is regulated by pivoting said lower wall for passage of fluids through said separating device in a horizontal direction, and wherein said separating device is divided into an upper part and a lower part, said upper part being of a first predetermined height for the fluids, after having impurities separated therefrom, to continue moving downstream through said separating device and said lower part being of a second predetermined height for capturing the impurities separated from the textile fibers;
- a hopper for collecting the impurities separated from the textile fibers, wherein said hopper is intercepted by an extractor having a seal;
- and
- a movable deflector knife which extends from a wall inside of said hollow containment parallelepiped.
A process for separating impurities from textile fibers in flake form during pneumatic transportation thereof using a separating device located between ducts connecting machines for processing the textile fibers, wherein said separating device includes a hollow containment parallelepiped of rectangular cross-section having an upper wall which is stationary and a lower wall which is pivotable, wherein said rectangular cross-section of said hollow containment parallel epiped is consistent with a cross-section of said ducts connecting said machines to said hollow containment parallelepiped, a rack fulcrum-mounted at a fulcrum at said upper wall so as to be pivotable within said hollow containment parallelepiped;
- a passage section of said hollow containment parallelepiped having a variable area, wherein said variable area of said passage section is regulated by pivoting said lower wall for passage of fluids through said separating device in a horizontal direction, and wherein said separating device is divided into an upper part and a lower part, said upper part being of a first predetermined height for the fluids, after having impurities separated therefrom, to continue moving downstream through said separating device and said lower part being of a second predetermined height for capturing the impurities separated from the textile fibers, a hopper for collecting the impurities separated from the textile fibers, wherein said hopper is intercepted by an extractor having a seal, and a movable deflector knife which extends from a wall inside of said hollow containment parallelepiped, said process comprising the steps of:
- adjusting a value of said second predetermined height between 10 and 70 mm, and preferably between 20 and 50 mm.
