Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
A kind of bag filter, as shown in Figure 1, including the babinet 2 with blast pipe 21 and discharge pipe 22,2 top of babinet
It is provided with cover board 23, lower section is fixedly connected with the supporting rack 1 being used to support.Exhaust gas in factory enters out of blast pipe 21, connects
It and is discharged from discharge pipe 22.
As shown in Figure 2 and Figure 3, the card 3 being fixedly connected with inside babinet 2 between blast pipe 21 and discharge pipe 22, makes
It obtains when exhaust gas is discharged from discharge pipe 22 and needs to first pass through card 3.The side of card 3 towards discharge pipe 22 is equipped with several filter bags
4 and the bag cage 5 for fixing filter bag 4（One is only shown in attached drawing as reference）, therefore exhaust gas is discharged from discharge pipe 22
Before need to first pass through filter bag 4 so that the dust that air contains stays in 4 surface of filter bag and is purified, avoid air by
Pollution.2 lower section of babinet is fixedly connected with the ash bucket 6 being connected to 2 inner cavity of babinet, and 6 downside of ash bucket is provided with ash discharging hole 61, ash discharging hole
61 lower sections are provided with dust collecting box 7.The dust in 4 table side face of filter bag falls to the ash bucket 6 of lower section, then from row after by gravity
Dust collecting box 7 is fallen at grey mouth 61.Ash discharge and filtering carry out together, and the dust in ash bucket 6 can be discharged in time, avoid powder
Dirt accumulates excessive trouble.
As shown in Fig. 2, since 61 moment of ash discharging hole is in the open state, exhaust gas flows into babinet 2 from blast pipe 21
After can be revealed from ash discharging hole 61, and then air is caused to be contaminated.In order to avoid exhaust gas is revealed from ash discharging hole 61, discharge pipe
22 are connected with exhaust fan 8.Exhaust fan 8 work when be capable of providing suction, into 2 inner cavity of babinet exhaust gas by suction court
Top is flowed, and is avoided exhaust gas from being flowed out from ash discharging hole 61 and is led to the trouble of atmosphere pollution.Accelerate exhaust gas to flow simultaneously, improved
Filter effect.Elbow 9 is fixedly connected with inside babinet 2 at blast pipe 21, the opening direction of elbow 9 is arranged away from ash bucket 6.Exhaust gas
When entering 2 inner cavity of babinet from blast pipe 21, it is oriented to and the direction flowing of separate ash bucket 6 by elbow 9.Ash bucket 6 it is tapered and
Upper opening is big, lower opening is small so that the size of ash discharging hole 61 reduces so that exhaust gas is not easy to flow out from ash discharging hole 61.
Dust is fallen simultaneously can be slid by gravity to dust collecting box 7 in 6 madial wall of ash bucket.
As shown in figure 4, under the larger environment of air humidity, moisture can be combined after entering babinet 2 with dust, so that powder
Dirt is adhered on 6 madial wall of ash bucket, forms a lot of obstacle, and dust is hindered to slide to dust collecting box 7.In order to avoid air humidity
Trouble that is larger and leading to ash discharge difficulty, 6 lateral wall of ash bucket are fixedly connected with electrothermal tube 14.After electrothermal tube 14 heats, pass through heat
Conduction, 6 madial wall temperature rise of ash bucket so that the dust fallen on ash bucket 6 will not be adhered to because of humidity on ash bucket 6.Electric heating
Side of the pipe 14 far from ash bucket 6 is provided with the protective shell 15 being fixedly connected with supporting rack 1, and protective shell 15 is made of heat-insulating material,
Such as：.Protective shell 15 can play electrothermal tube 14 protective action, while protective shell 15 can avoid people from replacing dust collecting box 7
When the trouble scalded by electrothermal tube 14.
As shown in Figure 2, Figure 4 shows, the top of card 3 is arranged at intervals with five anti-blowpipes 10,10 one end of anti-blowpipe pass through babinet 2 and
It is connected with electromagnetic impulse valve 11 and air accumulator 12, there are five escape pipe 101, outlets towards the side setting of card 3 for anti-blowpipe 10
Pipe 101 is located at right over the opening of corresponding filter bag 4.After starting electromagnetic impulse valve 11, compressed air is gone out from escape pipe 101,
Make the drastically bulging of filter bag 4, by impact vibration and back draught so that the dust on 4 surface of filter bag is detached with filter bag 4, then by
It is fallen in ash bucket 6 to gravity, avoids 4 surface fine dusts of filter bag excessive and influence the trouble of filter effect.Bag cage 5
Opening is equipped with Venturi tube 13, since the internal diameter of Venturi tube 13 is gradually reduced along blowback airflow direction so that blowback air circulates
Flow velocity is accelerated after crossing Venturi tube 13, enhances ash-removal effect.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
