Description

Industrial dust collector
Technical field
The present invention relates to a kind of industrial dust collector.
Background technology
Industrial dust collector is industrial conventional suction tool, its structure mainly comprises portable hand-push support, on described hand-push support, be fixed with dust bucket, induced-draught electric motor, in dust bucket, be equiped with dust removal and filtration core, on dust bucket, offer suction port, dust removal and filtration core is provided with dedusting air inlet and dedusting air outlet, and the described common circumference uniform distribution of dedusting air inlet is on the periphery of dust removal and filtration core, described dedusting air outlet is connected with induced-draught electric motor, therefore after induced-draught electric motor is opened, the external world is with the first suction of the suction port from dust bucket of air of dust, during through dust removal and filtration core, dust is isolated in outside dust removal and filtration core, air after purification enters from dedusting air inlet, from dedusting air outlet, discharge, although such structure setting can realize absorption and the processing of dust to external world, but absorb the outer surface that the dust major part of coming in can be attached to dust removal and filtration core, then each dedusting air inlet on clogging dust removal and filtration core progressively, thereby cause dust removal and filtration core to work, and then the service life of shortening dust catcher.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of novel industrial dust collector, this industrial dust collector can be circulated and automatically be cleaned dust removal and filtration core by blowback, thereby has effectively extended the service life of industrial dust collector.
For achieving the above object, the invention provides a kind of industrial dust collector, comprise portable hand-push support, dust bucket, dust removal and filtration core, solenoid directional control valve, and the induced-draught electric motor being connected with solenoid directional control valve, on wherein said solenoid directional control valve, offer first interface, the second interface, the 3rd interface and a back suction air inlet, and described first interface, the second interface, connection or the isolation each other of the 3rd interface and back suction air inlet realized by commutation by solenoid directional control valve, dust bucket and induced-draught electric motor are installed on hand-push support, dust removal and filtration core is installed in dust bucket, on dust bucket, offer suction port, on dust removal and filtration core, be evenly distributed in the dedusting air inlet of several oblique settings, on the upper surface of dust removal and filtration core, offer a dedusting air outlet, and described dedusting air outlet is connected by connecting pipe with the first interface of solenoid directional control valve, between dust removal and filtration core upper surface and dust bucket top cover, be also equiped with a blowback and cross filter core, blowback is crossed on the lower surface of filter core and is evenly distributed in several blowback air inlets, blowback is crossed on the upper surface of filter core and is offered a blowback air outlet, and described blowback air outlet is connected by connecting pipe with the second interface of solenoid directional control valve, the 3rd interface and the back suction air inlet of solenoid directional control valve are communicated with ambient atmosphere.
The invention has the beneficial effects as follows: adopt said structure, because the present invention has additional a blowback between dust removal and filtration core and dust bucket, cross filter core, and whether blowback is crossed filter core and worked and realized by commutating by solenoid directional control valve.When its operation principle is normal operation, after induced-draught electric motor is opened, air with dust is first inhaled into from suction port, then through dust removal and filtration core, filter, air after purification enters from dedusting air inlet, from dedusting air outlet, blow in the first interface of solenoid directional control valve, now solenoid directional control valve is connected first interface and the 3rd interface again, make the air that purified through dust removal and filtration core from the 3rd interface discharged to atmosphere; When the dust that adheres to when dust removal and filtration wicking surface is too much, now can start blowback circulation, be that solenoid directional control valve is connected first interface and the second interface, air enters from the second interface, under the pumping of induced-draught electric motor, lead to first interface, then through first interface, enter the dedusting air outlet of dust removal and filtration core, finally from dedusting air inlet, discharge, the air of now discharging also will be taken away the dust that is attached to dust removal and filtration core outer surface simultaneously, therefore also just realize the automatic cleaning to dust removal and filtration core, thereby effectively extended the service life of industrial dust collector; Same the present invention also can cross filter core to blowback and automatically clean, be that solenoid directional control valve is connected back suction air inlet and the second interface, outside air enters from back suction air inlet, through the second interface, enter the blowback air outlet that filter core is crossed in blowback again, finally from blowback, cross the blowback air inlet discharge of filter core, thereby realize the automatic cleaning that blowback is crossed to filter core, to guarantee that blowback crosses the normal operation of filter core, further extended the service life of industrial dust collector.
The present invention can further be set to described blowback and cross outer also coated being provided with of filter core and prevent that dust from filtering baffle plate from the blowback entering in blowback air inlet.
Adopt said structure, set up blowback and filter baffle plate, can avoid dust to enter into blowback from blowback air inlet and filter in-core.
The present invention can further be set to the coated isolation baffle plate that is provided with in outside, position of close dust bucket suction port on described dust removal and filtration core.
Adopt said structure, after induced-draught electric motor is opened in normal operation, suction port has powerful air draught power, therefore on dust removal and filtration core, between the position of close suction port and suction port, set up isolation baffle plate, can avoid the dust sucking in suction port directly to rush at dust removal and filtration core, thereby dust removal and filtration core is caused damage.
The present invention can further be set to also be equiped with in the suction port of described dust bucket the flow apron of unidirectional air intake.
Adopt said structure, set up the flow apron of unidirectional air intake, can guarantee the only inside air intake of suction port, and can not make inner air or dust discharge through suction port.
The present invention can further be set to be equiped with on the 3rd interface of described solenoid directional control valve eliminate the noise cotton.
Adopt said structure, described noise elimination cotton can be to finally from the air giving off in the 3rd interface processing of eliminating the noise.
