Description

In the proposed device for descaling water-heating boilers of steam boilers, in order to communicate the oscillating movements of the roller cutter mounted on a tube connected rigidly to the motor housing, the tube passes through: a rod that carries a circular body and receives rotation from the motor when the help of the flexible shaft passed through the hose. In FIG. 1 shows the device in longitudinal section; FIG. 2 is a front view of it .;

Drubka 2c impregnated with a cone 1 | a fixed nut 7, a connecting sleeve 4 is connected with a hose rigidly connected to the motor housing, inside of which a flexible shaft 5 is missed which receives rotation from the motor. Inside the tube 2, a rod 3 passing through it is placed, at the output end of which a body b is reinforced with a nut 8, and the other end is fitted with a flexible shaft 5; to reduce friction between

t | eubeoy 2 and rod 3 can be placed ball bearings

The device is inserted into the hot-water pipe and when the rod 3 is rotated, the hose remains stationary, the roller cutter, under the influence of the moving center of the rotating round body b, receives oscillatory movements during which the roller cutter is on the wall of the heating pipe and clears scale.

The subject matter of the invention.

A descaling device for boilers for steam boilers, characterized by the application of the resulting rotation from the motor using a flexible shaft 5 and sterish 3 round bodies b for communicating vibrations of the roller cutter 1, mounted on the surrounding rod 3 tube 2, connected to a string rigidly connected with motor case. i
