Fig. 2 is left TV structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As depicted in figs. 1 and 2, pulse bag type dust collector with automaton, comprise support 1, casing 2, blowing device 3, filter bag 7 and control device, filter bag 7 is located in the casing 2, the lower end of casing 2 and upper end are respectively equipped with air inlet 10 and air outlet 9, be provided with ash-discharging device 4 below the casing 2, described control device comprises the PLC controller, and the PLC controller is connected with pressure sensor and blowing device 3 circuit in being located at casing 2; Blowing device 3 be arranged on casing 2 above, blowing device 3 is connected with air compression plant by pipeline; Described blowing device comprises injection tube, nozzle and magnetic valve, and magnetic valve is located on the injection tube and with the PLC controller circuitry and is connected.
In the present embodiment, described air inlet 10 is connected with ash bucket, and ash bucket is connected with described ash-discharging device 4.According to different dedusting requirements, the outer wall of ash bucket can also arrange hopper wall vibrator among the embodiment, to strengthen the effect of deashing.Described ash-discharging device 4 comprises manual dust unloading device and automatic ash-discharging device, and according to different instructions for uses, the manual dust unloading device comprises star-shaped ash unloading valve, and automatic ash-discharging device comprises conveying worm 13.Described filter bag 7 upper ends are connected with filter bag installing rack 14, and connection is connected in filter bag 7 lower ends with the filter bag locating rack, be provided with deflector 8 between the filter bag 7.Be provided with air intake passage between described air inlet 10 and the air outlet 9, air intake passage is provided with volume damper 12.Also be provided with staircase platform 5 above the described casing, staircase platform 5 is provided with air intake passage switching mechanism 6.
The present invention adopts the unit-combination type structure, filter bag adopts film composite filtering material, not only can improve filtration velocity, and cleaner resistance reduction, stable, make cleaner be specially adapted to the dedusting of high temperature, high humidity dusty gas, industries such as cement, electric power.In the work time-histories of the present invention, dusty gas is entered by air inlet 10, and the deflector 8 in ash flue bucket makes that the part big dust particle is separated by the inertia force effect in the gas, directly falls into ash bucket.Dusty gas is by the laggard filter bag filtering area that enters casing 2 of ash bucket, and gas passes filter bag 7, and dust is delayed at the outer surface of filter bag 7, and purified gas is discharged by air outlet 9 after filter pocket mouths enters casing 2 again.Along with the prolongation of filtration time, the dust layer on the filter bag 7 is constantly thickeied, and the resistance of dedusting constantly rises, and when equipment resistance rose to setting value, ash-discharging device 4 was started working.During the equipment deashing, compressed air passes through each pulse valve in order with the extremely very brief time, nozzle on injection tube sprays to filter bag, filter bag is expanded rapidly produce vibration, and under the effect of inverted draft, ash bucket is stripped from and is fallen into to the dust that is attached on the filter bag outer surface, concentrated by ash-discharging device 4 by ash bucket and discharge.
