SU515537A1 - Installation for cleaning the inner surface of pipes - Google Patents

Description

one

The invention relates to the field of cleaning the inner surface of pipelines of various diameters and can be used in mechanical engineering.

Installations for cleaning pipes with fluid flow are known, consisting of an injection line, including a pumping station, control and regulating equipment, a docking device, a bathtub and a tank pallets.

It is also known a device for cleaning the inner surface of pipes with a fluid flow, comprising an injection line and a flow turbulator connected by a flexible coupling with a mechanism for reciprocating it in the flushing pipe.

The aim of the invention is to increase the cleaning efficiency and reduce the power of the washing installation.

This is achieved by the fact that the proposed installation is equipped with an ejector pipe for air suction installed between the injection line and the flushing pipe, and the flexible coupling of the turbulizer passes through the ejector pipe. The execution of the turbulizer is preferably in the form of a truncated cone with a concave large base.

FIG. 1 shows the block diagram of the proposed installation; in fig. 2 - turbulizer in

section; in fig. 3 - a nozzle for introducing into the flow of washing fluid a flexible coupling of the turbulizer and air by means of ejection. The installation contains a bath 1, on the side

the wall of which is fitted with a device 2 for connecting the flushed pipe 3 to the discharge line 4, including control and adjustment equipment 5, pumping station 6. The lower part of the bath forms a tank-pond 7 with partitions 8 and a filter 9. A branch pipe 10 with an ejector tube is installed 11, through which the bend 12 passes, for example a nylon fishing line,

connecting the turbulizer 13 of the flow with the mechanism 14 of the reciprocating movement of it in the flushed pipe. The installation works as follows. Pipe 3, cleaned by cleaning, is placed

in the bath 1 and docks to the delivery line 4. Pump station 6 through the filter 9 pumps fluid from the pallet tank 7 into the delivery line 4. The required parameters of the flow of cleaning fluid are set by the control equipment 5. At the same time, the mechanism 14 performs the reciprocating movement of the ducting apparatus 13 in the flushing pipe 3. Through the pipe 11 the pipe 10 is ejected

air that breaks laminar flow of washing liquid. Takil: In a manner, B, the flushing pipe is supplied with a stream of gas-liquid mixture, which pushes a turbulizer through it. The rate of advancement of the turbulizer is chosen to be less than the rate of flow of the stream, so that a highly turbulized stream of gas-liquid mixture flows in the gap between the pipe and the turbulator, which ensures high cleaning efficiency.

The steady advancement of the turbulator is ensured by its execution in the form of a truncated cone with a concave large base.
