Abstract

The invention is intended for paper machines and will find application in the pulp and paper industry. The purpose of the invention is to reduce water consumption by ensuring the reliability of the shower operation. A paper machine sprinkle contains shower devices located on the shower pipe 1 with a certain pitch. The device includes a hollow body 2 in which a nozzle 3 is movably mounted in a cylindrical bore, resting on the sealing ring 4, and a piston 5 with a cleaning rod 6. The piston is pressed against the nozzle by a spring 7, while the rod enters the central bore of the nozzle. A cover 8 with a gasket 9 is attached to the housing, on the side of the housing there is a finger 10, on which a link 11 is pivotally attached, which is pivotally connected to the link 12 and the legs 13, 14 connected in the same way with adjacent shower devices. The link 12 with its other end is hingedly connected to the pusher 15, through the through groove of which the finger 10 passes. There is an abutment 16 on the case. The case is connected to the shower pipe by the hole 17 and is attached to it by paws 19 - the sealing ring. The nozzle has peripheral holes 20 and is installed in the opening 21. 3 Il.

Description

The invention relates to a shower design and is intended for cleaning-clothing of paper-making machines and will be used in the pulp and paper industry.

The purpose of the invention is to reduce the flow rate by ensuring reliable operation of the shower.

FIG. 1 shows a device of a general view; in fig. 2 is a view A in FIG. and FIG. 3 - nozzles.

A paper machine roll will infect shower devices, pac-j.

Laid on the shower pipe 1 with a predetermined pitch. The device includes a hollow body 2, from which a cylindrical bore is movably mounted nozzles 3 supported on a sealing ring, and a piston 5 with a clearing rod 6. The piston is pressed against the nozzle by a spring 7, while the rod enters the central hole of the nozzle. A cover 8 with a gasket 9 is attached to the housing, on the side of the housing there is a finger 10, on which a link 11 is pivotally connected, which is pivotally connected to link 1.2 and the arms 13 and connected in the same way with adjacent spray devices. The link 12 with its other end is hingedly connected to the pusher 15, through the through groove of which the finger 10 passes. There is an abutment 16 on the case. The nozzle has peripheral holes 20 and is installed in the opening 21.

The shower works as follows.

When pressure is applied through the opening 17, the piston 5 compresses the spring 7, releases the opening nozzle 3 and presses against the gasket 9 with its end eliminating water leakage through the gap between the piston and the housing. The nozzle is pressurized with water against the sealing ring. When you turn off

The piston returns to its original position and the rod 5 cleans the nozzle hole.

After some time, depending. bridges on the quality of filtration of fresh water, as well as using light

foul water in front of the nozzle accumulates pollution. If they are large enough, cleaning will be ineffective. The device is cleared of accumulated soils with the pressure turned off by moving the pulses connecting the spray devices in the IB direction indicated by the arrow with a lever or other means (not shown). In this case, the pusher 15, turning around the finger 10, reaches the stop 16 and rises to the vertical position of the links 11 and 12. Raising it, the pusher will press the nozzles with the piston 5 and open the water passage through the cutouts of the nozzle (Fig. 3). When the pressure is switched on, the contaminants will be washed off by a stream of water and exit through an opening of 21 "

The return to the initial position occurs when moving the t g in the direction opposite to the arrow, after which the device is ready for operation,

invention formula

A paper machine drop, containing a hollow body with a water inlet, mounted in a nozzle body installation opening with a central water outlet and a coaxial nozzle, a spring-loaded piston with a rod for cleaning the nozzle hole, characterized in that in order to reduce water consumption by providing reliability of operation of the shower, the nozzles are provided with a pusher for moving along the axis of the housing and are made with peripheral holes communicating the housing cavity with the mounting opening.
