US 8,272,577 B2 · Apparatus for spraying a liquid

Abstract

An apparatus for spraying a liquid, such as a cleaning liquid or a lubricating liquid, onto a wire or onto a felt in a plant for paper production. The apparatus has pipeline for supplying the liquid and spray nozzles for ejecting the liquid. A shaft with a cleaning device for the spray nozzles or for the inner wall of the pipeline is disposed within the pipeline. The shaft includes a cylindrical sleeve which has a slotted guide and a thread and is arranged in a housing which adjoins the pipeline, the thread interacting with a control spindle and, furthermore, a bolt or the like being provided which can be adjusted transversely with respect to the housing and projects into the slotted guide in a first position, as a result of which, during a rotation of the control spindle, the shaft is displaced in the longitudinal direction of the pipeline. Here, a second bolt or the like is provided, by which the control spindle can be coupled to the cylindrical sleeve in terms of its rotation, as a result of which, after adjustment of the first bolt or the like out of the slotted guide, the shaft can be rotated by the control spindle.

Dependent claims

An apparatus for spraying a liquid onto a wire or onto a felt in a paper production facility, comprising:

a pipeline for supplying the liquid, said pipeline defining a longitudinal direction;
spray nozzles formed to eject the liquid;
a shaft with a cleaning device for the spray nozzles or for the inner wall of the pipeline disposed within said pipeline;
said shaft being configured with a cylindrical sleeve formed with a slotted guide and a thread and disposed in a housing adjoining said pipeline;
a control spindle having a thread disposed to mesh with said thread of said cylindrical sleeve;
a first engagement device disposed for transverse adjustment relative to said housing and projecting into said slotted guide in a first position, as a result of which, during a rotation of said control spindle, said shaft is displaced in the longitudinal direction of said pipeline;
a second engagement device disposed for coupling said control spindle to said cylindrical sleeve in terms of a rotation thereof, as a result of which, after disengagement of said first engagement device out of said slotted guide, said shaft is rotatable by said control spindle.
