Plate 12 connects, and the other end of tube body 11 is the round tube that aperture is slightly larger than middle part, and the lower section of tube body 11 is equipped with multiple Venturi tubes
13。
The upper surface of the injection tube installation crossbeam 2 is equipped with multiple bolts hole 21.
The bottom of the L shape connecting plate 12 is equipped with U-shaped hole 121.
Each Venturi tube 13 below the injection tube 1 corresponds to a through-hole 31.
The caliber of the injection tube 1 gradually successively decreases from centre toward two sides.
Working principle of the utility model is: the injection tube 1 of different tube diameters is fixed on bleed pipe installation cross in a certain way
On beam 2, each Venturi tube 13 below injection tube 1 corresponds to a dust-removal cloth-bag, and dust-removal cloth-bag is mounted on bag filter hole
In the hole of plate 3, when work, the air-flow into injection tube 1 is blown out by the Venturi tube 13 of injection tube lower part, has certain pressure
Air-flow be blown into dust-removal cloth-bag.
After adopting the above technical scheme, the utility model has the beneficial effect that the form that it is distributed with round reducing, warp is utilized
The principle for calculating and automatically controlling pressure drop is crossed, keeps deashing jetting pressure approximate impartial, is uniformly blown, jetting pressure is small, and compression is empty
Gas dosage is low, reduces energy consumption；Simultaneously as the reason that jetting pressure is low, improves the service life of filter material.
