Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a pipeline ventilation system. Background Art

[0002] In order to allow air to circulate better and ensure the quality of air people breathe, ventilation ducts are widely used in various places where people live and work, and the functional requirements for ventilation ducts are getting higher and higher. During the ventilation process, including exhaust and air supply, both work simultaneously to exchange air to achieve ventilation effects. The exhausted airflow needs to be processed into a pollution-free state before it can be discharged to avoid pollution to the environment. The supplied gas needs to be processed into a state that can be supplied for breathing. Dust removal is also required during the exhaust and air supply process to filter out dust, suspended matter, etc. in the air. The existing dust removal method mainly relies on the filtering equipment set at the port of the pipe. Although most of the dust and suspended matter in the air can be filtered out, it is inevitable that some small-sized dust and suspended matter escape the filtering equipment at the port and enter the pipe. In the long run, it is inevitable that the pipe will be blocked, affecting its ventilation effect. Utility Model Content

[0021] During ventilation, the filter 4 disposed in the ventilation pipe 1 is used to prevent external dust from entering the room. When the filter 4 is blocked, the cleaning brush 2 is pushed into the ventilation pipe 1 to clean the filter 4. At the same time, the dust shield 3 is also pushed into the ventilation pipe 1 to form a partition at the outlet end of the filter 4 to prevent the dust raised by the cleaning brush 2 from entering the room during the cleaning of the filter 4. After cleaning, the cleaning brush 2 is pulled down to drive the first plug 5 to reset so that the first opening is re-closed; the dust shield 3 is pulled down to drive the second plug 6 to reset so that the second opening is re-closed.
