Industrial dust collector

Technical field

The utility model relates to a kind of industrial dust collector.

Background technology

Industrial dust collector is that suction tool commonly used is gone up in industry, and its structure mainly comprises portable hand push support, is fixed with dust bucket, induced-draught electric motor on the described hand push support; Be equiped with the dust removal and filtration core in the dust bucket, offer suction port on the dust bucket, the dust removal and filtration core is provided with dedusting air inlet and dedusting air outlet; And the common circumference uniform distribution of described dedusting air inlet is on the periphery of dust removal and filtration core, and described dedusting air outlet is connected with induced-draught electric motor, therefore after induced-draught electric motor is opened; The air of the extraneous band dust at first suction port from the dust bucket sucks; During through the dust removal and filtration core, dust is isolated in outside the dust removal and filtration core, and cleaned air passes gets into from the dedusting air inlet; Discharge from the dedusting air outlet; Though such structure setting can realize the absorption and the processing of dust to external world, absorb the outer surface of the most of meeting of the dust of coming in attached to the dust removal and filtration core, progressively stop up each dedusting air inlet on the dust removal and filtration core then; Thereby cause the dust removal and filtration core can't operate as normal, and then shorten the service life of dust catcher.

Summary of the invention

To the deficiency of prior art, the purpose of the utility model is to provide a kind of novel industrial dust collector, and this industrial dust collector can clean automatically the dust removal and filtration core through the blowback circulation, thereby has prolonged the service life of industrial dust collector effectively.

For realizing above-mentioned purpose; The utility model provides a kind of industrial dust collector; Comprise portable hand push support, dust bucket, dust removal and filtration core, solenoid directional control valve, reach the induced-draught electric motor that is connected with solenoid directional control valve; Offer first interface, second interface, the 3rd interface and a back suction air inlet on the wherein said solenoid directional control valve, and connection or the isolation each other of described first interface, second interface, the 3rd interface and back suction air inlet realizes that through switching-over dust bucket and induced-draught electric motor are installed on the hand push support by solenoid directional control valve; The dust removal and filtration core is installed in the dust bucket; Offer suction port on the dust bucket, be evenly distributed in the dedusting air inlet of several oblique settings on the dust removal and filtration core, offer a dedusting air outlet on the upper surface of dust removal and filtration core; And described dedusting air outlet connects through being connected pipeline with first interface of solenoid directional control valve; Also be equiped with a blowback between dust removal and filtration core upper surface and the dust bucket top cover and cross filter core, blowback is crossed on the lower surface of filter core and is evenly distributed in several blowback air inlets, and blowback is crossed on the upper surface of filter core and offered a blowback air outlet; And described blowback air outlet connects through being connected pipeline with second interface of solenoid directional control valve, and the 3rd interface and the back suction air inlet of solenoid directional control valve are communicated with ambient atmosphere.

The beneficial effect of the utility model is: adopt said structure, because the utility model has additional a blowback and cross filter core between dust removal and filtration core and dust bucket, and whether blowback is crossed filter core and is worked and realized through commutating by solenoid directional control valve.When its operation principle is operate as normal; After induced-draught electric motor was opened, the air of band dust was inhaled into from suction port earlier, filters through the dust removal and filtration core then; Cleaned air passes gets into from the dedusting air inlet; Blow in first interface of solenoid directional control valve from the dedusting air outlet, this moment, solenoid directional control valve was connected first interface and the 3rd interface again, and the air that purified through the dust removal and filtration core is arranged to atmosphere from the 3rd interface; When the dust that adheres to when the dust removal and filtration wicking surface is too much; Can start the blowback circulation this moment, promptly solenoid directional control valve is connected first interface and second interface, and air gets into from second interface; Under the pumping of induced-draught electric motor, lead to first interface; Get into the dedusting air outlet of dust removal and filtration core then through first interface, finally discharge from the dedusting air inlet, the air that discharge this moment is also with the dust of taking away simultaneously attached to the dust removal and filtration core outer surface; Therefore also just realized automatic cleaning, thereby prolonged the service life of industrial dust collector effectively the dust removal and filtration core; Same the utility model also can be crossed filter core to blowback and clean automatically; Be that solenoid directional control valve is connected the back suction air inlet and second interface, outside air gets into from the back suction air inlet, gets into the blowback air outlet that filter core is crossed in blowback through second interface again; Finally cross the blowback air inlet discharge of filter core from blowback; Thereby the automatic cleaning that realization is crossed filter core to blowback is crossed the operate as normal of filter core to guarantee blowback, has further prolonged the service life of industrial dust collector.

The utility model can further be set to said blowback and cross outer also coating of filter core and be provided with the blowback baffle that prevents that dust from getting in the blowback air inlet.

Adopt said structure, set up the blowback baffle, can avoid dust to enter into blowback and filter in-core from the blowback air inlet.

The utility model can further be set to be provided with partitions near coating outside the position of dust bucket suction port on the said dust removal and filtration core.

Adopt said structure; Because after induced-draught electric motor is opened in normal operation; Suction port has powerful air draught power; Therefore setting up partitions between near the position of suction port and suction port on the dust removal and filtration core, the dust that can avoid in suction port, sucking directly rushes at the dust removal and filtration core, thereby the dust removal and filtration core is caused damage.

The utility model can further be set to also be equiped with in the suction port of said 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 inner air or dust are discharged through suction port.

The utility model can further be set to be equiped with on the 3rd interface of said solenoid directional control valve eliminate the noise cotton.

Adopt said structure, described noise elimination cotton can be to the air that finally gives off in the 3rd interface processing of eliminating the noise.
