For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of spraying and blowing system roll-over pulsed dust collector, it comprises upper box 1, middle casing 3, filter bag 8, lower box 4, ash discharge cone 5 and discharging wind stopping device 6, ash discharge cone 5 lower ends are provided with discharging wind stopping device 6, ash discharge cone 5 upper ends are provided with lower box 4, be provided with inner core 19 in the lower box 4, lower box 4 is provided with middle casing 3, in the middle casing 3 filter bag 8 is housed, middle casing 3 is provided with upper box 1, wherein: described upper box 1 is provided with loam cake 11, loam cake 11 passes through bolting with upper box 1, and loam cake 11 is connected by hinge 9 with upper box 1.
Further, described loam cake 11 comprises cover plate 13, lid 12, card 16 and anti-blow cleaning dust device, and cover plate 13 is contained on the lid 12, and lid 12 lower ends are provided with card 16, and card 16 is provided with the anti-blow cleaning dust device.
Further, described anti-blow cleaning dust device comprises impulse electromagnetic valve 14, air chamber 15, air jet pipe 17 and nozzle 18, impulse electromagnetic valve 14 is arranged on the card 16, air chamber 15 is arranged on card 16 times, impulse electromagnetic valve is connected with air jet pipe 17 14 times, air jet pipe is connected with nozzle 18 17 times, and nozzle 18 is suitable for reading corresponding with filter bag 8.
Further, described card 16 circumference are provided with bolt hole, and it is shaped as " n " shape.
Further, described filter bag 8 upper ends are provided with connecting plate 10, on the top board of casing 3, are provided with sealing gasket between the top board of connecting plate 10 and middle casing 3 during connecting plate 10 is contained in by bolt.
The beneficial effects of the utility model are:
The utility model is simple in structure, with low cost, its upper box is provided with loam cake, loam cake can open, filter bag therefrom takes out in the casing, like this, the maintainer can open loam cake, above deduster filter bag is taken out, and then maintenance, change filter bag, improved operating efficiency greatly, operation is also more easily simple, the bolt hole that is provided with on the card circumference be shaped as " n " shape, can be easy to open loam cake, so just reduce maintainer's labour intensity, also can prevent losing of bolt and nut.
