Description

This invention relates to the field of washing pipelines and other hollow articles.

The aim of the invention is to improve the quality of washing.

Pa the drawing shows a schematic diagram of a stand for washing hollow products. The bench has a washing fluid injection line 1, including pressurized filter 2, a filter 3. To the pressure pipeline 1 after the filter 3, using a pressure vessel filling line 4 with a regulated throttle 5 and a fluid supply line 6. A pressure line is connected to a pressure vessel 7. A liquid supply line 6 to the pressure line is equipped with a check valve 8 A gas supply line 9 includes a valve 10, a storage tank 11 and a three-position valve 12, which a single line 13 with the upper part of the pressure vessel 7 and a line 14 with the supply fluid supply line 1 further along the liquid movement than the pressure vessel filling line 4 7. Level sensors 15 and 16 are installed in the pressure vessel 7, and a sensor in the storage tank 11 pressure 17. With the level sensors 15 and 16 and the pressure sensor 17, the control unit 18 is connected with the operation of the distributor 12. Depending on the version of the sensors, the control unit .18 can be performed, for example, on elements of pneumatic automation or

In line 19 of the drain stand. Installed tank 20 with a gas separator 21.

The stand works as follows. The washing liquid from the tank 20 through the pumping pump discharge line 1 is supplied by pump 2 through the filter 3 to the hollow product to be added. In addition, the hollow product from the pressure tank 7 through the fluid supply line 6 to the pressure pipe is also periodically added to the hollow product. washing liquid with high flow. The washing liquid passes through the cavity of the product being flushed through the drain line 19 through the gas separator 21 and returns to the tank 20.

The pressure vessel 7 is filled with a washing-out brush through the lenses — by 4 fillings of the pressure vessel, and the capacity of the fluid supply is adjusted to the filling throttle

The capacity of supplying a fluid to a proimprg could the product along the injection line 1 remain sufficient to create a fluid flow in the cavity of the product at a speed of at least 3-5 m / s, i.e. sufficient to transport detached particles without deposition in the product cavity.

If it is necessary to install several parallel pumps in the stand for flushing large diameter pipes, the pressure tank filling line 4 can be connected to a separate injection line.

When the pressure tank 7 is empty, a signal is sent to the control unit 18 from the lower level sensor 16 and the latter switches the valve 12 to the position B, i.e. when the pressure vessel 7 is filled with liquid, the gas from it through line 13 through distributor 12 and line 14 is forced into the injection line 1, where a gas-liquid flow is created, which improves the transportation of contaminants in the product cavity. The connection of the line 14 to the injection line 1 further downstream of the liquid than the line 4 for filling the pressure tank is necessary for filling the pressure tank 7 with a washing liquid. At the end of the filling of this capacity, the signal from the upper level sensor 15 is fed to the control tank 18, while if it receives a signal from the pressure sensor 17, i.e. if the storage tank 11 of the gas supply line 9 is filled with gas to a predetermined pressure, the valve 12 switches to the position b and the accumulated gas enters the pressure tank 7, producing, from the last second, displacing the liquid with a high capacity through line 6 and partly through line 4 to line 1 pumping. and further into the washed product, where the liquid produces a cleansing action.

- When the fluid is completely expelled from the pressure vessel 7, the signal from the low level sensor 16 goes to the control unit and the latter switches the distributor 12 to position B and then the cycle repeats, npii achieving the specified quality of cleaning the product turns off the pump 2, closes the valve 10, and the distributor translates in position a.
