Air pipe dedusting device and dedusting method thereof

Abstract

The invention discloses an air pipe dedusting device and a dedusting method thereof. The air pipe dedusting device comprises a first air pipe, a second air pipe, a dedusting sliding core, a connecting pulling rod, a sealing plate and a power stretching mechanism; a fresh air port and an air returning port are symmetrically formed in the two sides of the pipe wall of the first air pipe, and fresh air and returning air are lead to the indoor through a filter; the second air pipe communicates and is connected with the first air pipe, and an air exhausting port for leading exhausted air to the outdoor is formed in the second air pipe; the dedusting sliding core is provided with a dedusting head located on the upper part of the dedusting sliding core, and the dedusting head is in clearance fit and connected with an inner cavity of the first air pipe; the connecting pulling rod is connected to the bottom of the dedusting head, and the sealing plate is located at the bottom of the dedusting sliding core; the sealing plate is used for sealing the position between the first air pipe and the second air pipe; and the power stretching mechanism is used for driving the dedusting head to move from the upper end inside the first air pipe to the bottom inside the first air pipe. According to the air pipe dedusting device and the dedusting method thereof, the problems can be solved effectively, frequent disassembling and washing for the filter are not required, more time and energy of users are saved, and the service life of the filter can be prolonged greatly.

Description

technical field [0001] The invention relates to the field of heating, ventilation and air conditioning, and relates to an air duct dust removal device and a dust removal method thereof. Background technique [0002] At present, the ventilation ducts on the market, after being used for a period of time, due to the dust and other particles attached to the duct wall, the new return air will bring the dust into the filter, and the filter will soon become dirty and blocked, causing the user to spend more time and frequently Remove and wash the filter (frequency: 1-2 months). Contents of the invention [0003] In view of the above technical problems, the present invention proposes an air duct dust removal device, which saves the user more time and energy and greatly prolongs the service life of the filter without frequent dismantling and cleaning of the filter. [0004] In order to realize above-mentioned technical purpose, the present invention adopts following technical schem...
