Abstract

SUMMARY OF THE INVENTION The device comprises a drum with a reciprocating movement, a flexible sleeve, tapes extending along its entire length, rollers with an electric motor and brushes fixed to it, and a system for supplying compressed air. When filling with compressed air, the sleeve is unwound from the drum, and the belts are lifted up. the electric motor that rotates the brushes At the end of the cleaning process, the pressure of the compressed air in the housing is relieved, the electric motor returns to its original position, the tapes are wound on the drum 2

Description

The invention relates to the purification of flues and flues from various dust deposits and can be used in chemical, metallurgical mining, construction and other industries

As a prototype, a device was selected to prevent the accumulation and removal of dust deposited in the ducts. In the known device, the cleaning element is made in the form of flexible pipelines, which are pairwise fastened together by plates that act as scrapers, and are freely laid on the bottom of the duct. Holes are made around the perimeter of the pipelines. When compressed air is supplied into flexible pipelines, the air discharged through these openings agitates the settled dust. The compressed air pressure in the pipelines is different and alternately changing, which ensures their movement under the influence of reactive force along the bottom of the gas duct one way or another

The disadvantages of the prototype - does not provide high-quality cleaning of dust deposits having increased adhesive ability of the complexity of the installation of the device

The purpose of the invention is to improve the quality of cleaning and increase manufacturability

The goal is achieved in that the device for cleaning chimneys comprising a housing, a flexible cleaning element with surface-cleaning devices, a compressed air supply system connected to it, is provided according to the invention, a drum installed in the housing, on which a cleaning element made in the form of a sleeve is wound , the second end of which is turned inside out and fixed hermetically around the perimeter of the housing with the possibility of reciprocating movement of the sleeve. At the same time, at the end of the turned sleeve is installed with the possibility of reciprocating movement of the electric motor on which the rollers are fixed. Through the rollers are directed tapes running along the outer surface of the sleeve along its entire length on both sides. Cleaning devices

filled in the form of brushes fixed rotatably on an electric motor.

The drawing schematically shows the proposed device.

The device for cleaning chimneys consists of a housing 1, in which a drum 2 with an electric drive mounted on it is placed (not shown in the figure). A sleeve 3 is wound on the drum 2. The second end of which is turned inside out and hermetically fixed around the perimeter of the housing 1. Along the outer surface of the sleeve 3 pass from two sides along its entire length of the tape 4, directed through the rollers 5 mounted on the electric motor 6, on which are fixed with the possibility of rotation of the brush 7 for cleaning the pipe 8. The electric wire 9 for supplying current is laid with hoses on the sleeve 3. The housing 1 is connected to a system 10 for supplying a working agent (compressed air)

The device operates as follows

The device is installed in the pipe to be cleaned 8, by System 10, compressed air is supplied into the housing 1, when filled, the sleeve 3 starts to be wound from the drum 2, turns out and rises. At the same time, the tapes 4 extending from both sides along the outer surface of the sleeve 3 and directed through the rollers 5 are turned out together with the sleeve 3, lifting up the electric motor 6, which rotates the brushes 7 fixed on it, which clean the soot from the inside of the pipe 8. An electric current is supplied through an electric wire 9, which is laid with hoses on the sleeve 3.

At the end of the cleaning process, the pressure of the compressed air in the housing 1 is released. The sleeve 3 together with the electric motor 6 is returned to its original position by means of an electric drive that is mounted on the drum 2. The tapes 4 passing through the rollers 5 are wound together with the sleeve 3 on the drum 2 and the electric motor 6 is returned to its original position.

The use of the invention allows to improve the manufacturability of the device, due to the simplicity of its preparation for work, and significantly improve the quality

cleaning the inner surface of chimneys from soot.
