Problems solved by technology

[0008] However, this solution has the disadvantage that the assembly required, in particular for moving the cleaning head, is very complicated and expensive
In addition, the required mechanical and hydraulic components are always prone to failure and require regular maintenance
[0009] Furthermore, the cleaning device requires a relatively large installation space
This leads to the fact that such cleaning systems cannot be used in suction rolls with small diameters

Embodiment Construction

[0069] Figure 1a , 1b and 1c schematically show different designs of fluidic oscillators, as they are known from the prior art. These fluid oscillators are suitable for use in oscillating nozzles 20 according to various aspects of the invention. However, the invention is not limited to these embodiments of fluidic oscillators. In general, all types of fluid oscillators are suitable.

[0070] Fluid can enter the flow space through the inlet 1 . when necessary, such as Figure 1c Accelerating nozzles, for example in the form of tapers, can be provided, as shown. Subsequently, the fluid enters the oscillation chamber 3 . Depending on the type of oscillator, a dam 6 in the form of an island 6 can be provided in the oscillation chamber 3 . Alternatively or additionally, a return channel 4 can also be provided, which in turn guides part of the fluid flow back in the direction of the inlet 1 . The fluid leaves the oscillator at outlet 7 as an oscillating jet 10 .

Abstract

The invention relates to a cleaning device, in particular for a suction roller of a plant for producing or treating a fibrous material web, the cleaning device comprising a distribution line via which a cleaning fluid can be supplied, and a plurality of cleaning nozzles, at least one, in particular all, cleaning nozzles are embodied as oscillating nozzles. The invention further relates to a suction roller and to a method for cleaning a suction roller.

Description

technical field [0001] The invention relates to a cleaning device according to the preamble of claim 1, in particular for a cleaning device for a suction roll of a plant for manufacturing or processing fibrous material webs, and to a suction roll according to the preamble of claim 11 and to a suction roll according to the Method for cleaning a suction roll according to the preamble of claim 13 . Background technique [0002] As in the production of nonwoven products, in the production of paper, cardboard or tissue products suction or blowing rolls are used at many points. These rolls have perforated roll sleeves. A negative pressure is applied during operation of the suction roll so that air / water or other fluid flow is sucked through the perforations of the roll sleeve. Similarly, in the case of blown rolls an overpressure is applied so that a fluid flow is blown through the roll sleeve. [0003] The perforated fluid flow through the suction roll usually carries with it ...
