The bag-type dusting unit
Technical field: the utility model relates to air dust remover, particularly relates to a kind of bag-type dusting unit.
Technical background: at present huge at the dust removal by ventilation equipment of industries such as building materials, pottery, metallurgy, casting, mine, coal, electric power and mechanical chemical industry, complicated operation, cost an arm and a leg, maintenance is inconvenient, service life is low, it is also very not obvious to remove airborne impurity effect, can not satisfy the needs of enterprise's production development.
Summary of the invention: the purpose of this utility model will provide a kind of bag-type dusting unit exactly.It can well overcome the existing problem of present cleaner.The purpose of this utility model is to realize like this, a kind of bag-type dusting unit is made up of filter box, blower fan, cloth bag, dust-collecting and vibrating mechanism, hopper, ash exhauster, it is characterized in that: be provided with the outlet of blower fan and pure air on the upper left side of casing, the left side of casing is provided with the inlet (dust contained gas), the vertical surface of casing is provided with inspection door, and the lower left of casing is provided with ash exhauster and sewage draining exit; In the inner chamber of casing, the top is provided with the clean room and communicates with blower fan; The left side communicates with the inlet (dust contained gas) is provided with filter box, and the right of filter box is provided with several ten cloth bags, and the right of cloth bag is provided with dust-collecting and vibrating mechanism; The below of filter box is provided with the pressure reduction alarm, and the inner chamber below of casing is provided with hopper.The utility model compact conformation; simple to operate; easy to maintenance; long service life; but follow procedure control work automatically; not only be applicable to the dust removal by ventilation of industries such as building materials, pottery, metallurgy, casting, mine, coal, electric power and mechanical chemical industry, and can be used for the recovery of dust, help improving working conditions and environmental protection.
The utility model can be divided into A type and two kinds of patterns of Type B.The A type is not with hopper and ash exhauster, Type B band hopper and ash exhauster.According to the filter area difference be divided into 18,23,28,36,45,56 6 kind of dedusting unit.

Description of drawings: Fig. 1 is the front view in the utility model structural representation;
Fig. 2 is the left view in the utility model structural representation;
1. inlet (dust contained gas), 2. filter box, 3. pressure reduction alarm, 4. ash exhauster, 5. sewage draining exit, 6. hopper, 7. inspection door, 8. dust-collecting and vibrating mechanism, 9. cloth bag, 10. clean room, 11. blower fans, the outlet of 12. pure airs, 13. casings.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, the utility model bag-type dusting unit is made up of filter box 2, blower fan 11, cloth bag 9, dust-collecting and vibrating mechanism 8, hopper 6, ash exhauster 4, it is characterized in that: be provided with blower fan 11 and pure air outlet 12 on the upper left side of casing 13, the left side of casing 13 is provided with inlet (dust contained gas) 1, the vertical surface of casing is provided with inspection door 7, and the lower left of casing 13 is provided with ash exhauster 4 and sewage draining exit 5; In the inner chamber of casing, the top is provided with clean room 10 and communicates with blower fan 11; The left side communicates with inlet (dust contained gas) 1 is provided with filter box 2, and the right of filter box 2 is provided with several ten cloth bags 9, and the right of cloth bag 9 is provided with dust-collecting and vibrating mechanism 8; The below of filter box 2 is provided with pressure reduction alarm 3, and the inner chamber below of casing 13 is provided with hopper 6.During concrete enforcement, it is filtrate that cloth bag adopts 729 polyester terylene, has the intensity height, good heat resistance, acid-proof, alkali prevention, damp proof, the characteristics that the life-span is long.When starting shooting, the utility model causes negative pressure in the dust chamber owing to blower fan, dusty gas is drawn into the filter box from air inlet, behind the cloth bag filtration, just be attached to the cloth bag outer surface, clean air enters the clean room by filtrate and is closed to indoor or atmosphere by blower fan, thereby reaches the purpose that purifies air or collect solid particle in the dusty gas.Operation along with unit, the dust that the cloth bag outer wall adheres to increases gradually, and the resistance of unit sharply rises, because the effect of pressure reduction alarm, blower fan is stopped, the mechanical vibrator deashing mechanism is worked automatically simultaneously, forces dust stratification to fall, and dust is discharged through hopper and ash exhauster, (if deashing directly can be dropped on belt conveyor or feed bin) with A type deduster, after the time of setting, vibration body just quits work automatically, and this just finishes a deashing working cycles.
