SU1143A1 - Pipeline cleaner - Google Patents

Description

There are facilities for cleaning pipelines, especially those for beer, with a tank and a cleaning fine-grained substance, driven by B using a jet device, which during cleaning is connected between the inlet fittings, closing the pipeline to be cleaned in a circular cycle, and between the return pipe and the jet apparatus has a constant outflow of excess water, allowing the cleaning agent to perform a circuit. Further, there are devices in which, directly under the tank, there is a multi-pass valve fitted to the pipeline connecting springs, while a two-pass valve equipped with the connecting cable is attached to the upper end of the supply pipe for supplying and discharging the cleaning agent pipes; by means of a connecting pipe, a two-way valve communicates with a multi-way valve, the cleaning substance being passed through the pipe being cleaned in the passing or opposite directions and in both cases returning to the tank. You dreamed, however, that the existing

devices suffer more or less adversely reflected defects in the cleaning process, namely: in devices in which the cleaning substance is driven by a jet device, this substance can be conducted through the cleaning pipeline only in one direction, as a result of which, in case of clogging of the pipeline with cleaning substance - the cleaning process is immediately terminated. On the other hand, in devices with a multi-pass valve attached directly under the tank and equipped with connecting spur, which are in communication with the fitted spur for the inlet and outlet piping with a two-wire tap, the cleansing substance can, however, allow skipping if the cranes are properly installed; via the pipeline to be cleaned in both directions, but can never be maintained in a continuous circuit. In this case, the cleaning agent, after each run through the pipeline being cleaned, is guided by appropriately re-arranging both taps alternately to the supply valve.

pipe, then into the tank. Permanent repositioning of taps during cleaning requires a lot of time and constant maintenance and monitoring of the device.

The proposed fixture is intended for cleaning pipelines, especially those for beer produced by fine-grained cleaning agent in a pressurized tank that can be distilled through the pipeline to be cleaned in passing or opposite directions, and with passing traffic the cleaning agent is maintained in a continuous circuit, While the reverse movement of the cleaning agent returns to the tank, where it accumulates and has the goal of eliminating these shortcomings.

The pressure agent inlet into the tank, just like the cleaning agent, from the tank to the pipeline to be cleaned and returning it to the tank is produced by means of a two-way valve installed on the closing lid of the tank, equipped with appropriate connecting processes, for supplying and discharging pipe substance; An open branch pipe mounted on the shut-off cap serves to drain dirty flushing water. Thanks to such a device, the cleaning agent is maintained in a continuous circuit, the pressure means, after the completion of cleaning, as well as in the case of blockage of the pipeline, is simply transferred by two-way valve through the pipeline in the opposite direction, due to which the cleaning agent is entrained and accumulates in the tank.

FIG. 1 and 2 depict an exemplary embodiment of the invention, with FIG. 1 shows a device in longitudinal section and partly a view of it, and FIG. 2 is a device for the return movement of the cleaning agent.

resting in a metal frame 2, which is locked by a crane 3. The upper edge of the metal frame 3 is equipped with eyelets 4 for passing posts 5 attached to the base plate 6. On the top edge of the glass tank 1 there is a metal ring 7 with an appendage 8 that surrounds the tank and eyelets 9, which again, they are used to pass the pillars 5 tightened with nuts 10. Thus, the glass tank is fixed between the metal ring 7 and the metal frame 2. A metal sieve 11 is laid in the metal ring 7. Glass tank 1 is flat but it is closed by a locking cap 12 screwed onto a metal ring 7. The inner cap 12 is provided inside with a branch pipe 13, with an internal thread, into which the inlet pipe 14 is screwed. A dual valve 15 placed on the closure cap, fitted with connecting nozzles 16, is connected to it, 17 and 18 for inlet and outlet pipes. An open port 19 is installed in the shut-off cap to discharge dirty washing water, and there is also an opening for passage of the return pipe 20.

Having connected both cleaned pipelines, their free ends are connected to the processes 16 and 17 by means of hoses, and the two-way valve is installed so that the supply pipe is open. When opening the pressure pipe, the pressure means is passed through a two-way valve 15 and a supply pipe 14 to the tank 1 and from there, together with the substance to be cleaned, through the valve 8 to the pipe being cleaned; then the whole mass is returned through the discharge pipe and the two-way valve to the tank 1, from where the flushing water is discharged through the open discharge pipe 19. Thus, the cleaning substance is maintained in a continuous circulation. Upon completion of the cleaning, or if it is accidentally discontinued, the two-way valve is transferred to the connection of the supply pipe with the discharge pipe, as a result of which the constant circulation of the cleaning substance is terminated. Through two pass

The valve and the connecting process of the discharge pipe of the pressure medium are then passed through the pipeline in the opposite direction and return, together with the cleaning agent remaining in it, through the valve to the reservoir; The flushing water is again discharged through an open discharge pipe.

SUBJECT OF THE PATENT.

Pipeline cleaner, with reservoir included in it, with fine-grained cleaning material, entrained by the injection fluid, characterized by the use of a two-way valve 15, serving at one of its positions (Fig. 1) to communicate the branch pipe 16 for the discharge pipe with the branch pipe 13 for the pipe 14 and a pipe 17 for one end of the pipe to be cleaned with a pipe 18 for pipe 20, together with pipe 14 being introduced into a tank 1 containing fine-grained cleaning material, and a valve 5 communicating with the other end being cleaned with a different position (Fig. 2), connects pipe 16 with 17 and 13 with 18 in order to obtain reverse current in the pipeline being cleaned, in both cases and in the other case through drain pipe 19.
