Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is elaborated.But protection scope of the present invention is not limited to following embodiment, the simple equivalence namely in every case done with the present patent application the scope of the claims and description changes and modifies, and all still belongs within patent covering scope of the present invention.
As shown in Figure 1, 2, a kind of explosion-proof industrial dust collector, comprise storage vat 6, this storage vat upper port is fixed with cover plate 61, cover plate is connected to cloth bag 7 and pipe joint 8, this pipe joint connects the gas outlet end 22 of a pneumatic negative pressure device 10, and the air inlet end 21 of this pneumatic negative pressure device is by flexible pipe 11 connecting handle 12 and cleaner head 13 successively; Pneumatic negative pressure device comprises shell 1, is provided with the sprue 2 running through this shell in this shell, and one end of this sprue forms air inlet end 21, and the other end of this sprue forms gas outlet end 22; Also be provided with an air cavity 3 around this sprue in this shell, this case surface is provided with compressed air inlet 4 and is communicated to this air cavity; This air cavity is also provided with several runners 5 towards this sprue, and the end of this runner forms jet 51 and is communicated to this sprue, and the airflow direction of this jet and negative pressure air-out mouth forms acute angle.
Wherein, runner described in several is uniformly distributed on described air cavity.Described jet is circular hole and the one kind of shape of annulus slit, or is other shapes.Described air inlet lateral surface is provided with import screw thread 211, and described negative pressure air-out mouth lateral surface is provided with outlet screw thread 221, also can arrange flange, anchor ear etc.Described shell is that stainless steel and the one kind of material of aluminium alloy are made, or other hard material.Described storage vat downside is provided with universal wheel 9.Described cloth bag is detachably fixedly connected on described cover plate by the first anchor ear 71.Described cover plate is fixed on described storage vat by fast disassembly type anchor ear 62.Described flexible pipe is connected on the air inlet end of described pneumatic negative pressure device by fast joint 14.Described fast joint inserts ash intake valve 15, and this ash intake valve is fixed on the air inlet end of described pneumatic negative pressure device.
