Abstract

Usage: cleaning the inner surface of pipes from various contaminants. SUMMARY OF THE INVENTION: a device for cleaning the inner surface of pipes includes elastic plate consoles connected at one end to the shaft with scraper elements at their free ends, the scraper elements have a centrifugal clamp to the surface being cleaned. It is also provided with an additional hub installed with the possibility of covering the ends of the consoles connected with the shaft. The additional hub has a tapered recess with a large base at the end of the hub from the exit side of the consoles. In this case, the consoles are equipped with weights installed at one end with scraper elements on the opposite side. 3 ill.

WITH

The invention relates to the field of cleaning, and more particularly, to devices for cleaning the inner surface of pipelines of various kinds of contaminants. A device is known for cleaning the inner surface of pipelines, comprising scraper elements mounted on the shaft.

A disadvantage of the device is its design complexity, which does not allow its use for cleaning the inner surface of pipes of small diameter with a small wall thickness.

A device is known for cleaning the inner surface of pipes, comprising elastic plate consoles connected at one end to the shaft with scraper elements at their free ends and a centrifugal clamp of the scraper elements to the surface being cleaned.

A disadvantage of the device is the inability to process pipes with a small wall thickness on it, since they can be damaged due to the fact that the force is not controlled by pressing the scraper elements against the inner surface of the pipes.

The purpose of the device according to the invention is to prevent damage to thin-walled pipes by adjusting the clamping force.

This goal is achieved due to the fact that the device for cleaning the inner surface of the pipes, containing elastic plate consoles connected at one end to the shaft with scraper elements at their free ends and centrifugal clamping of the scraper elements to the surface to be cleaned, is equipped with an additional hub installed with the possibility of protection VI VI VI

cotton wool connected to the shaft of the ends of the consoles and having a conical recess with a large base on the end face of the hub from the exit side of the consoles, while the consoles are equipped with weights mounted on one end with scraper elements on the opposite side

In FIG. 1 shows a longitudinal sectional cleaning apparatus; in FIG. 2 is a section AA in FIG. 1; Fig. 3 is a general arrangement of a device.

The device 1 for cleaning the inner surfaces of the pipes 2 contains elastic plate consoles 4 and stops 5 mounted on the shaft 3. The elastic plate consoles 4 at their free ends 6 are equipped with scraper elements 7 made in the form of cutters 8 with weights fixed on the opposite side 9. Opposite, the ends 10 of the consoles 4 connected with the shaft 3 are enclosed by a hub 11 having a conical recess with a large base on the end face of the hub from the side of the consoles exit, mounted on the shaft 3 with pins 12, on which the impeller 13 is fixed, In order to balance the pressing force of the scraper elements 7 and stabilize them against vibration and protect the impeller blades 13 from damage, a centering ring 14 is freely mounted on the hub 11, on which the stops 5 are rigidly fixed. Lock washers 15 are installed on both sides of the ring.

The coarse cleaning unit comprises a trolley 16 with an electric motor 17 mounted on it, to which a cleaning device 1 is connected via a shaft 3 and is located inside the pipe 2, which is hermetically fixed with its end face by means of a flexible hose 19 with a hopper 20 for collecting the treated slurry.

The device operates as follows .v

The pipe 2 to be treated is hermetically connected by a flexible hose 19 to the hopper 20. From the side of the free end of the pipe 2, a cleaning device 1 is inserted into it, connected by a shaft 3 to an electric motor 17. When electric power is supplied, the shaft 3 rotates and rotates the impeller 13 and through the elastic plate consoles 4 to the scraper elements 7. When the shaft 3 is rotated by centrifugal forces, the elastic plate consoles 4 are deflected by pressing the cutters 8 against the inner surface of the processed pipe 2, cleaning its inner surface shit.

The adjustment of the clamping force of the scraper elements 7 to the surface to be cleaned of the pipes 2 is carried out by means of the size of the conical recess on the hub 11.

adjusting the deflection angle of the free ends 6 of the consoles 4 with cutters 8 at their ends.

The force to press the cutters 8 is directly proportional to the weight of the weights and the number of

revolutions of the electric motor. The rotation speed and mass of the weights are selected depending on the degree of contamination of the inner surface of the pipe.

To clean the inside

pipes along its entire length to the trolley 16 translational motion is transmitted.

The rotation of the impeller 13 provides the removal of the scraped off sludge through the hose 19 into the hopper 20.

To balance the pressing force of both free ends 6 of the plate consoles 4, making them resistant to vibration and preventing damage to the impeller 13 on the hub 11 is provided

a centering ring 14 with stops 5 made in the form of arches, lock washers 15 enclose the ring 14 from longitudinal displacement.
