Device for cleaning container interior walls
A cleaning device for cleaning an interior wall of a container includes a rotatable driveshaft which is supported in a nozzle head mounted for rotation about an axis extending transversely to the driveshaft. A nozzle holder is mounted on the driveshaft has an arm for holding a nozzle for ejecting a liquid under pressure. The driveshaft and/or the nozzle head are reversibly pivotable via a gear mechanism, with an auxiliary drive connected to the gear mechanism for driving the nozzle holder.
1. A cleaning device for cleaning an interior wall of a container, comprising:
a rotatable driveshaft;
a nozzle head supporting the driveshaft and mounted for rotation about an axis extending transversely to the driveshaft;
a nozzle holder mounted on the driveshaft;
at least one nozzle held in an arm of the nozzle holder for ejecting a liquid under pressure;
a gear mechanism configured for reversibly pivoting at least one of the driveshaft and nozzle head; and
a drive connected to the gear mechanism for driving the nozzle holder,
wherein the gear mechanism is configured in at least one of two ways, a first way in which the gear mechanism is constructed as a coupling gear including a first connecting rod having one end connected to a driven crank disc and another end connected by an articulated joint to a coupling member to which a second connecting rod is connected, said second connecting rod being in operative connection with the driveshaft, and a second way in which the gear mechanism includes a gear driven by a toothed gear drive to which a crank is connected to a coupling gear attached at a drive disc.
2. The cleaning device of claim 1 , wherein the crank disc is driven by the drive.
3. The cleaning device of claim 1 , wherein the coupling member is constructed as a two-armed lever pivotably supported at on a rotating pin, said first and second connecting rods being spaced from the rotating pin at a distance which is variable.
4. The cleaning device of claim 3 , wherein the rotating pin supports a spindle nut which is connected to a thread spindle of the coupling member, said thread spindle being configured for rotation in the coupling member.
5. The cleaning device of claim 1 , wherein the nozzle holder includes two of said arm for holding nozzles in one-to-one correspondence, said nozzles being aligned and oriented in opposite direction.
6. The cleaning device of claim 1 , wherein the drive is an electrically-operated, pneumatically-operated or hydraulically-operated drive.
7. A cleaning device for cleaning an interior wall of a container, comprising:
a rotatable driveshaft;
a nozzle head supporting the driveshaft and mounted for rotation about an axis extending transversely to the driveshaft;
a nozzle holder mounted on the driveshaft;
at least one nozzle held in an arm of the nozzle holder for ejecting a liquid under pressure;
a gear mechanism configured for reversibly pivoting at least one of the driveshaft and nozzle head; and
a drive connected to the gear mechanism for driving the nozzle holder,
wherein the gear mechanism has a driven crank disc, said drive having at least two oppositely oriented recoil nozzles attached to angled drive arms and connected via a toothed gear with the crank disc and supplied with liquid under pressure.
8. The cleaning device of claim 7 , wherein the nozzle holder includes two of said arm for holding nozzles in one-to-one correspondence, said nozzles being aligned and oriented in opposite direction.
9. The cleaning device of claim 7 , wherein the drive is an electrically-operated, pneumatically-operated or hydraulically-operated drive.
