End is provided with waterproof cover.
Preferably, the second relief valve is installed on the first tracheae that dust filter outlet is connected with air exhauster, on
The exit for stating the second relief valve is also associated with a dust filter and an air-breathing bucket by third tracheae.
Preferably, the structure of above-mentioned dust filter is：Including a filter frame, is installed in above-mentioned filter frame
One filter screen.
Preferably, above-mentioned filter screen vertical direction installation, and the side Cheng Shangkuan of filter frame bottom, close air-breathing bucket
Under narrow funnel-form, and one dust-collector is installed in funnel bottom.
It is isolated preferably, being equipped on above-mentioned first tracheae between the second relief valve and dust filter
Valve.
Preferably, being equipped with the second filter on the second tracheae, between waterproof cover and relief valve.
Compared with prior art, the utility model has the following advantages：
A kind of dedusting air draft reverse-filling mechanism structure of the utility model is simple, and need not dismantle can be automatically by dust mistake
Filters clean does not interfere with producing line efficiency, and is provided with relief valve on pipeline, not will produce gas and pours in down a chimney phenomenon.

Specific implementation mode
Multiple embodiments that the utility model will be disclosed with schema below, as clearly stated, in many practices
Details will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit this practicality newly
Type.
About its " first " used herein, " second " etc., the meaning of order or cis-position is not especially censured, also non-use
The component described with same technique term just for the sake of difference with limiting the utility model or operation.
Referring to Fig. 1, its schematic diagram for a kind of dedusting air draft reverse-filling mechanism of one embodiment of the utility model.Such as figure
A kind of dedusting air draft reverse-filling mechanism shown, that the utility model discloses, includes the funnel at indoor production line
Air-breathing bucket 1, be connected with the first tracheae 21 on the top of air-breathing bucket 1, dust filter 3 be connected in turn on the first tracheae 21
With air exhauster 4, it is connected with the second tracheae 22 in the gas outlet of air exhauster 4, relief valve 5 is installed on the second tracheae 22,
Second tracheae 22 is bent upwards, and is pierced by building ceiling, and the end of the second tracheae 22 is provided with waterproof cover 6.
This is in order to overcome the problems, such as that the when of cleaning filter screen needs entire exhaust system shutting down this, in dust filter
Second relief valve 7 is installed on the first tracheae 21 that 3 outlets are connected with air exhauster 4, the exit of the second relief valve 7 passes through third
Tracheae 23 is also associated with a dust filter 3 and an air-breathing bucket 1, and the structure of above-mentioned dust filter 3 is：Including one
Filter frame 31, a vertically-mounted filter screen 32 in filter frame 31, and 31 bottom of filter frame, close to air-breathing bucket 1
A dust-collector 33 is installed in side at funnel-form wide at the top and narrow at the bottom, and in funnel bottom, since air exhauster 4 is ceaselessly taken out
Gas so that gas enters pipeline from the air-breathing bucket 1 of major loop, and dust is blocked by the filter screen 32 of major loop, with pushing away for time
Move, many dusts gathered on the filter screen 32 on major loop so that air by resistance increase, and 4 efficiency of exhaust fan is not
It can reduce so that the negative pressure in the first tracheae 21 between 4 air inlet of exhaust fan and the dust filter 3 of major loop increases, when
