Claims
- 1. An apparatus for removing deposits of material coatings from the inner surfaces of containers, such as lavatory bowls, heat exchanger containers, heat exchanger tubes, and the like, said cleaning apparatus comprising an elongate housing having a longitudinal axis with handle means on one end and being adapted to be immersed at least partially in a liquid within a container to be cleaned, a plurality of substantially bar-like, high frequency vibrator elements extending across the interior of said housing from one side to the other side of said housing, said bar-like vibrator elements being positioned at different axial positions along the longitudinal axis of said housing, and said bar-like vibrator elements at the respective axial positions being progressively angularly offset from the bar-like vibrator elements at other axial positions into different angular positions as viewed in the axial direction of said housing, and the opposite end portions of each of said bar-like vibrator elements being shaped to fit the outline of the inner surface of the elongate housing and being affixed thereto along the entire area of contact therebetween, whereby the power emission per unit of area from the outer surface of the housing is relatively uniform in directions perpendicular to the axis of the housing, thereby enabling the deposits of material coatings on the inner surfaces of the container to be effectively removed without rotating the housing of the cleaning apparatus relatively to the wall of the container.
- 2. An apparatus for removing deposits of material coatings from the inner surfaces of containers, such as lavatory bowls, heat exchanger containers, heat exchanger tubes, and the like, as claimed in claim 1, in which said bar-like vibrator elements are supplemented by additional free-hanging vibrator elements connected to the inner surface of the housing and supported solely by the housing.
- 3. An apparatus for removing deposits of material coatings from the inner surfaces of containers, such as lavatory bowls, heat exchanger containers, heat exchanger tubes, and the like, as claimed in claim 1, in which:
- said substantially bar-like vibrator elements are supported within said housing solely by their end portions being affixed to the housing.
- 4. Apparatus for removing deposits of material coatings from the inner surfaces of containers, such as lavatory bowls, heat exchanger containers, heat exchanger tubes, and the like, as claimed in claim 1, characterized in that each of said bar-like vibrator elements includes a plurality of vibrator units, all of said vibrator units along each bar-like vibrator element acting along the same axis of oscillation.
- 5. Apparatus for cleaning material coatings and deposits from the inner surfaces of containers as claimed in claim 1, characterized in that said bar-like vibrator elements are supplemented by additional vibrator elements supported by and affixed to the inner surface of the housing.
- 6. Apparatus for removing deposits of material coatings from the inner surfaces of containers, such as lavatory bowls, heat exchanger containers, heat exchanger tubes, and the like, as claimed in claim 1, characterized in that the respective end portions of said bar-like vibrator elements comprise adapter pieces shaped to conform to the adjacent inside surfaces of the elongate cylindrical housing and being rigidly affixed between the vibrator element and the inside surface of said housing.
- 7. Apparatus for cleaning material coatings and deposits from the inner surfaces of containers, said cleaning apparatus comprising a spherical housing adapted to be immersed in a liquid within the container to be cleaned, a plurality of bar-like ultrasonic vibrator elements extending diametrically across the interior of said housing, the end portions of each of said bar-like vibrator elements being shaped to fit the outline of the inner surface of the spherical housing and being affixed thereto along the area of contact therebetween, whereby the power emission per unit of area from the outer surface of the spherical housing is relatively uniform in all directions thereby enabling a container to be effectively cleaned without rotating the housing of the cleaning apparatus relative to the wall of the container.
- 8. Apparatus for cleaning material coatings and deposits from the inner surfaces of containers as claimed in claim 1, in which a cubical centerpiece is positioned at the center of said spherical housing, each of said barlike vibrator elements including a pair of bar-like vibrator units extending radially between opposite sides of the cubical centerpiece and the inner surface of the spherical housing, each said vibrator unit being connected to the centerpiece and to the area of the inner surface of the housing with which it is in contact.
- 9. Apparatus for removing material coatings from the inner surfaces of containers for cleaning the containers, said apparatus comprising a housing adapted for immersion in a liquid in the container to be cleaned, said housing having a plurality of vibrator elements adapted to put the walls of the housing into high frequency oscillations, said apparatus being characteristized in that at least certain of said vibrator elements are constructed as substantially bar-like elements extending across the interior of the housing into contact with opposite sides of the housing, each of said bar-like vibrator elements having its opposite end portions shaped to conform to the adjacent inside surfaces of the wall of the housing with which they are in contact and being affixed thereto over the area of contact, said housing being spherical, and said bar-like vibrator elements being arranged extending through the center point of said housing.
- 10. Apparatus for removing material coatings from the inner surfaces of containers as claimed in claim 9, characterized in that the respective end portions of said bar-like vibrator elements comprise adapter pieces shaped to conform to the inside surface of the spherical housing and being rigidly affixed between the vibrator element and the inside surface of said spherical housing.
- 11. An apparatus for cleaning coating deposits from the inner surfaces of containers, such as sanitary bowls, heat exchanger containers, heat exchanger tubes, and the like, said cleaning apparatus comprising an elongated cylindrical housing with two ends and having a longitudinal axis, at least one of said ends of said housing being closed, said housing having handle means at the other end and being adapted to be immersed at least partially in a liquid within a container to be cleaned, a plurality of substantially bar-like high frequency vibrator elements extending diametrically across the interior of the housing perpendicular to said axis, said vibrator elements being positioned at different axial positions along the longitudinal axis of said housing, the vibrator elements at the respective axial positions being oriented into different angular positions as viewed looking along said axis, with the angular offset between successive vibrator elements being an acute angle, and the opposite end portions of each bar-like vibrator element being shaped to fit the outline of the inner surface of the elongate housing and being affixed thereto over the entire area of contact therebetween, whereby the power emission per unit of area from the outer surface of the housing is relatively uniform in directions perpendicular to the axis of the housing, thereby enabling the coating deposits to be effectively cleaned from the inner surfaces of the container without rotating the housing of the cleaning apparatus relatively to the inside surfaces of the container.
