Pneumatic air conduit cleaner

Abstract

The present invention relates to an pneumatic device for cleaning ventilation ducts which includes a guiding air hammer, a turning conduit, a air-supply pipe and a slewing mechanism for the conduit. The guiding air hammer is a hollow spherical or hemispherical shape, connected to the turning conduit and provided with jets of air for cleaning and jets of air for guiding on its rear arc wall. When cleaning the ventilation duct, according to the principle of air motion, the guiding air hammer cleans out of dust lain on the inner walls and in all the corners of the ventilation duct with the air-supply pipe stretching means retracting and stretching the air-supply pipe, without an operator entering the ventilation duct. The air-supply pipe stretching means may be controlled by manually operation or program composition. The design of the invention may be used for cleaning all ventilation ducts with polygonal section. According to the present invention, the pneumatic device for cleaning ventilation ducts has compact structure, has an advantage of automated operation, may clean any corner of the ventilation duct, decreases the number of operators and reduces the labor strength of the operator.

Description

Technical field: [0001] The invention relates to a cleaning tool, more specifically, the invention is a pneumatic ventilation duct cleaner for cleaning ventilation ducts. Background technique: [0002] In the prior art, the cleaning of ventilation ducts is generally carried out manually with high-pressure air trucks, and high-pressure air is used to clean the ducts. For ventilation ducts with relatively large diameters, cleaning personnel need to drill into the ducts for cleaning. , resulting in labor-intensive clean-up and poor working conditions. The applicant applied for a Chinese patent application with the application number 200310113320.X on November 14, 2003, and the invention name is a patent application for a ventilation duct cleaner. The technical solution in this patent application is that the walking vehicle drives the ventilation duct The cleaner enters the pipeline for cleaning work, its volume is large, and the loss of aerodynamic force is relatively large. ...
