Device for cleaning and/or moistening surfaces or spaces, in particular for peeling off the filter cakes from filter plates in paper manufacturing

摘要

In a device for cleaning and/or moistening surfaces or spaces, for precipitating dust or foams, in particular for peeling off the filter cakes from filter plates in paper manufacture, pipe branches start from a spray liquid feed pipe and serve to hold spray cans which apply the liquid to the object to be cleaned or moistened. A cylindrical housing is releasably attached to the connection part of the pipe branch, which serves to feed the liquid, in the manner of a T-element and has a radial recess in which a nozzle having a widened portion is arranged in such a way that the nozzle outlet located at the apex point or approximately at the apex point of the widened portion projects into the interior of the cylindrical housing. The cylindrical housing is penetrated axially by a manually operable cleaning device for the nozzle outlet. By means of such a device it is possible to clean individual contaminated or blocked nozzles without the entire system having to be shut down for this purpose. The contaminated or blocked nozzles remain in their mounted position during the cleaning process. Since as a result of this the outage times of the entire system can be virtually reduced to zero, it is now possible to a very large extent to dispense with the expensive fresh water which was used previously to a certain extent and with the equally expensive systems for cleaning and processing circulation water. Instead, the unrestricted use of circulation water containing impurities is possible.
