Abstract
A cleaning body intercepting apparatus for a tube-type heat-exchanger, with the apparatus including a cylindrical body, a pair of outer gratings disposed in the cylindrical body so as to receiving cleaning bodies from the heat-exchanger, at least a pair of inner gratings within the outer gratings for forming a pair of throat portions each adjacent to the side wall of the cylindrical body, and extraction tubes each disposed under each of the throat portions. The pair of throat portions each are surrounded by the outer and inner gratings so that the cleaning bodies from the heat-exchanger are introduced into the throat portions. The cleaning bodies passed through the throat portions are taken out the cylindrical body through the extraction tubes.

Apparatus for intercepting cleaning bodies used for cleaning a tube-type heat-exchanger, the apparatus comprising:
- conduit means through which a liquid cooling media flows;
- first sieve means disposed in said conduit means for defining a relatively narrow region in a downstream portion of the conduit means and for introducing the cleaning bodies into the narrow region which allowing the liquid cooling media to pass therethrough;
- second sieve means substantially disposed within said first sieve means for forming a restricted passage means for the cleaning bodies in the narrow region and for introducing the cleaning bodies into the restricted passage means in cooperation with said first sieve means while allowing the liquid cooling media to pass therethrough into the conduit means;
- and
- extraction passage means provided on said conduit means and partially disposed downstream of said restricted passage means for receiving the cleaning bodies from said first and second sieve means through said restricted passage means.
Apparatus for intercepting cleaning bodies used for cleaning a tube-type heat-exchanger, the apparatus comprising:
- a cylindrical body through which a cooling water flows;
- a pair of first grating disposed in said cylindrical body for defining a relatively narrow region in a downstream portion of the conduit means, the pair of first gratings receiving and introducing the cleaning bodies from said heat-exchanger into the relatively narrow region;
- a shaft means connected to each of the first gratings for controlling a positioning thereof, said shaft means extending in a direction traversing a center axis of said cylindrical body and being rotatably supported by said cylindrical body;
- a pair of second gratings substantially disposed with said first gratings for forming a pair of throat portions at lower portions of said first and second gratings;
- a further shaft means connected to each of said second gratings for controlling a positioning thereof, said further shaft means extending perpendicularly to said shaft means of said first gratings and being rotatably supported by said cylindrical body;
- and
- a pair of extraction tubes each so mounted on said cylindrical body that a first end of each of said extraction tubes project into said cylindrical body, the first ends of said extraction tubes being disposed under said throat portions whereby the cleaning bodies from said first and second gratings are removed from said cylindrical body through said throat portions and extraction tubes.
An apparatus for intercepting cleaning bodies used for cleaning a tube-type heat-exchanger, the apparatus comprising:
- a cylindrical body in which a cooling water flows;
- a pair of first gratings disposed in said cylindrical body for defining a narrow region in a downstream portion of the conduit means, the pair of first gratings receiving and introducing the cleaning bodies from said heat-exchanger into the narrow region;
- first shaft means secured to the first pair of gratings and extending in a direction traversing a center axis of said cylindrical body and being rotatably supported by said cylindrical body for controlling a positioning of the pair of first gratings;
- two pair of second gratings substantially disposed within said first gratings for forming a pair of throat portions at the lower portions of said first and second pairs of gratings;
- second shaft means fixed to said two pair of second gratings and extending perpendicularly to said first shaft means and being rotatably supported by said cylindrical body for controlling a positioning of the two pair of second gratings;
- and
- a pair of extraction tubes each so mounted on said cylindrical body that a first end of each of said extraction tubes projects into said cylindrical body and is disposed under one of said throat portions.
