Description of the drawings
Fig. 1 is a kind of schematic diagram of the dust filtering system of paper machine closed hood of the utility model embodiment.
Fig. 2 is the vertical view of the filter of the utility model embodiment.
Specific implementation mode
In the following, the substantive distinguishing features and advantage of the utility model are further described in conjunction with example, but this practicality is new
Type is not limited to listed embodiment.
As depicted in figs. 1 and 2, a kind of dust filtering system of paper machine closed hood of the present embodiment includes air inlet 1,
Gas outlet 2, filter 3 and filter chamber 4, the air inlet 1 and gas outlet 2 are connected to filter chamber 4 respectively.In the filter chamber 4
Equipped with polylith partition board 5, the interval of partition board 5 is arranged, and gas channel 6 is formed between partition board, and gas channel 6 includes inlet channel 61, mistake
Channel 62 and outlet passageway 63 are crossed, the inlet channel is connected to air inlet 1, and inlet channel both sides are equipped with spoiler 7.The mistake
It crosses channel 62 to be arranged between inlet channel 61 and outlet passageway 63, filter 3 is arranged in outlet passageway and is located at gas outlet 2
Lower section.Filter 3 includes cartridge filter 31 and cleaning plant 32, and cleaning plant 32 includes rocking handle 321, cleaning arm 322 and connecting rod
323, in 323 one end of connecting rod and above cartridge filter, the connecting rod stretches into cartridge filter the setting of rocking handle 321.Cleaning arm 322
In cartridge filter 31,322 one end of cleaning arm is connect with connecting rod, and the other end is contacted with filtering tube inner surface 311.Above-mentioned technical proposal
In, the dust of paper machine closed hood discharge enters filtration system by the air inlet 1 of side, is disturbed due to being equipped in inlet channel
Flowing plate enables dust-contained airflow to be flowed along spoiler, to make flow rotation, forms certain centrifugal separating effect so that portion
Divide dust separation；It can increase to extend the flow path of air-flow by transition passage is arranged and collect dust in filter chamber
Space, while gas flow temperature can be reduced, reduce damage of the high temperature to filter.In addition, by the way that cleaning plant is arranged, serve as
When the dust being infected on filter is more, pass through the rotation of rocking handle so that link rotatable, to make cleaning arm scrape in cartridge filter
Wall makes cartridge filter shake, to make dust be detached from.Those skilled in the art gram it is found that the rocking handle can be connect with driving device,
And driven by devices such as motors, to realize automatic cleaning.In above-mentioned technical proposal, due to air-flow from air inlet into it is fashionable just
Speed is higher, uses centrifugation mode in inlet channel, the paper dirt of larger particles is filtered, to reduce the mistake of filter
Filtering pressure power realizes classified filtering, the time for extending filter cleaning and replacing.
As depicted in figs. 1 and 2, in the present embodiment, the interval of spoiler 7 setting of 6 both sides of the inlet channel, spoiler 7
It is obliquely installed downwards.Through the above technical solutions, dust-contained airflow spiral is enable to decline.Spoiler 7 includes bending part 71,
Bending part 71 is vertical with spoiler 7.Air-flow can be reduced toward the corner flowing between spoiler and partition board by bending part.
In the present embodiment, the transition passage 62 is U-shaped, and guide plate 8 is equipped in transition passage, and the polylith partition board 5 wraps
