Above-mentioned box house, air inlet top are provided with baffle, and side is hung with more filter cloth bags under the baffle, on above-mentioned baffle top
A conduit is put in outside cabinet, nozzle corresponding with every filter cloth bag is provided on conduit, is located in above-mentioned conduit
One end outside cabinet is provided with a gas source.
Preferably, being provided with isolating valve in the position of above-mentioned air inlet, isolating valve and case are located on the air inlet
An exhaust outlet is provided between body.
Preferably, a unidirectional check-valves is arranged on the outside of above-mentioned exhaust outlet.
Preferably, being connected with the impulse electromagnetic valve of a control conduit switching between gas source and conduit.
Preferably, being provided with a difference gauge for being merely able to measurement box house and external pressure difference on cabinet.
Compared with prior art, the utility model has the advantage that
A kind of formula dust-extraction unit free of demolition of the utility model, structure is simple, easy for installation, high dust collection efficiency, Er Qieneng
Fine medicinal material powder is enough recycled, is increased economic efficiency.

Specific embodiment
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 does not apply this with limitation practical new
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 limiting the utility model just for the sake of difference with same technique term or operation.
Referring to Fig. 1, its schematic diagram for a kind of formula dust-extraction unit free of demolition of an embodiment of the present invention.As schemed
Show, a kind of formula dust-extraction unit free of demolition that the utility model discloses, the cabinet 1 including cylindrical shape, 1 lower part of cabinet is at funnel
Shape is provided with a discharge port 11 in bottommost, and a revolving valve 2 is installed at discharge port 11, is provided at the top of cabinet 1
Gas outlet 12 is equipped with a Three-way butterfly valve 3 at gas outlet 12, and the one outlet of the Three-way butterfly valve 3 is connected with guide duct 8,
Another outlet closing, is provided with air inlet 13 close to bottom funnel-shaped portion position in cabinet 1, inside cabinet 1, on air inlet 13
Portion is provided with baffle 14, has more filter cloth bags 15 in 14 underhung of baffle, puts in one outside cabinet 1 on 14 top of baffle
Root conduit 4 is provided with nozzle 41 corresponding with every filter cloth bag 15 on conduit 4, is located at one outside cabinet 1 in conduit 4
End is provided with a gas source 42.In normal work, the air inlet 13 of cabinet 1 is connected with exhaust duct, and Three-way butterfly valve 3 is by outlet
Mouth 12 is connected to guide duct 8, and after filter cloth bag 15, dust is blocked in the outside of filter cloth bag 15 for air draft；Passing through one
After the air draft of section time, the outside of filter cloth bag 15 has had accumulated a large amount of dust, if cleared up not in time, passes through in air draft
Filter cloth bag 15 will be very big, influences the working efficiency of exhaust fan in exhaust system, at this point, closing exhaust fan, uses threeway
Butterfly valve 3 disconnects gas outlet 12 and guide duct 8, blows from gas source 42 to nozzle 41, using back draught by dust from filter cloth
Bag 15 separates, and the dust after separation falls into the funnel position of 1 lower part of cabinet, opens the revolving valve 2 of discharge port 11, ash can be realized
The cleaning of dirt.
Because when gas source 42 is blown, air-flow can not be very big, if cabinet 1 opens wide, great pressure, institute will not be generated
Set between isolating valve 5 and cabinet 1 on air inlet 13 referring to Fig.2, be provided with isolating valve 5 in the position of air inlet 13
It is equipped with an exhaust outlet 17, while a unidirectional check-valves 16 is set on the outside of exhaust outlet 17, accordingly even when gas source 42 generates
Biggish wind will not blow into exhaust system pipeline, can only be discharged from exhaust outlet 17.
It is multiple that the impulse electromagnetic valve 6 of 4 switching of control conduit is connected between gas source 42 and conduit 4 refering to fig. 1, this
Sample enters in conduit 4 from the air that gas source 42 is blown out at pulsed, and being equivalent to makes filter cloth bag 15 produce certain vibration, from
And keep efficiency of dust collection higher.
A difference gauge 7 for being merely able to 1 inside and external pressure difference of measurement cabinet is provided on cabinet 1, due to filter cloth
15 after having accumulated more dust, air permeable rate can reduce much bag, at this time if the dedusting fan of dust pelletizing system after
Continue and blow into cabinet 1, then the pressure difference inside and outside cabinet 1 will increase, at this time if the differential pressure that difference gauge 7 measures has reached setting
Value, then control system control isolating valve 5 is closed, and Three-way butterfly valve 3 disconnects gas outlet 12 and guide duct 8, and gas source 42 is into conduit 4
Inflation, realizes the automation of dedusting.
In conclusion in one or more embodiments of the utility model, the embodiment party of upper described only the utility model
Formula is not intended to limit the utility model.To those skilled in the art, the utility model can have various changes
And variation.It is all the utility model spirit and principle interior any modification, equivalent replacement, improvement and so on, should all include
Within the scope of the claims of the utility model.
