Device for self-cleaning spray pipes

For cleaning objects of all kinds, it is known Use spray pipes from which nozzles distributed in any way over the length and / or circumference Pressurized cleaning fluid, in particular water, emerges and thus cleans the associated surface.

Palis unclarified or partially clarified water is used, it can happen that the impurities clog the spray nozzles more or less over time, whereby the cleaning effect diminishes or does not occur entirely. Ss is therefore necessary to clean such sprays from time to time, which is cumbersome and usually makes the reduction of sprays needed to clean them inside to be able to _"water-; ¥ ii-ederum cumbersome and time consuming.

The fire avoids these laughable parts by means of a device for the self-cleaning of such spray pipes, according to the control system there is at least one brush body in the interior of the spray tube in the form of an elongated v / alze, preferably divided into several at a distance one behind the other Brush rings arranged from the rest position on one

End of the spray tube in the rest position at the other end of the spray tube and vice versa ". During this movement, the spray tube is rubbed off on the entire inner jacket and so cleaned. Dirt particles deposited on the nozzle orifices are taken along and moved to the two rest positions of the brush the spray tube ends transported. They are picked up by the brush and pressed outwards to the flushing outlet. To steer in the direction of movement of the brush body is a 4-way valve behind the inlet at one end of the spray tube the spray liquid, preferably Was.ser, installed. The one Path leads into the spray pipe and the other path into a connecting line to the other end of the spray tube. In order to be able to remove the dirt that accumulates during cleaning from the spray pipe to the outside, is expediently at one end of the spray tube or in the vicinity of the Rest positions for the brush body, a device for discharging the dirt, preferably in three-dimensional form from closable dirt drainage nozzles intended*

Further details of the inflation can be found in the drawing illustrated embodiment explained. Show it

Fig. 1 “A spray tube according to the innovation in Side view and

ffig. 2. the elevation of the spray tube in an enlarged view

In the exemplary embodiment, 1 denotes the spray tube, which has a number of flat jet nozzles 2 distributed over its length, which can have a scattering angle between 60 and 120 *

The spray liquid, preferably water, is fed in at the connector 3, which opens into a 4-T7ege valve 4.

One outlet of the Yier-way Y-valve opens directly into the spray tube 1 , the opposite outlet via a bend and a connecting hose into a second tube 5, which leads to the opposite end 6 of the spray tube. This second pipe is rigidly connected to the spray pipe 1 with the aid of connecting elements 7. The one in Pig. 2 cleaning brush 8 shown is designed like a roller and consists of several brush rings made of Hylon bristles, one behind the other,

This brush 8 is through the pressure of the spray pipe water at the in Pig. 1 position of the Yier-way valve shown 4 initially from the rest position at the left end of the spray tube 1 in the direction of Pig. 2 arrows of moved left to right, comes to rest at the other end 6 of the spray tube and closes end 6 in the process.

This occurs when changing the Yier-way Y-valve 4 by 180 ° Cleaning water at 6 from the opposite side into the spray tube 1 and moves the brush in the opposite side Direction from the rest position at 6 to the rest position at the other end of the spray tube, which is connected to the Yier-V / ege-Yentil 4 connects. With each of these movements of the brush 8, the entire inner wall of the spray tube 1 is rubbed off and the

In particular, dirt accumulated at the nozzle mouths at 9 (I ¹ Ig · 2) is taken along, which gets into the Ireie through the dirt drainage connection.

The cleaning effect achieved in this way is excellent and achieved with very little economic effort. In addition, the brush itself does not do any cleaning needs, because it does not collect any dirt itself because it is always in a of the two rest positions at the spray tube ends remains.
