Detailed description of the invention
As shown in Figures 2 to 4, a kind of embodiment weighing storehouse, weighing storehouse in this embodiment comprises frame, frame is provided with hopper 10, the cover plate 11 at hopper 10 top is provided with charging aperture and gas outlet, charging aperture is used for being communicated with the discharging opening of conveying worm 30, hopper 10 base plate is provided with discharge gate, and go out to be provided with striker plate at discharge gate, unlike the prior art: the cover plate 11 at the hopper top that the present embodiment provides is installed with dust-proof air-breather, this dust-proof air-breather comprises the tubular shell 24 extended along the vertical direction, the cross section of this tubular shell 24 is circular, be provided with in tubular shell 24 and tubular shell inner chamber is divided into epicoele 27, the packing plate 26 of cavity of resorption 25, tubular shell 24 lower end has the air inlet be communicated with cavity of resorption 25, upper end has the exhaust outlet be communicated with epicoele 27, the gas outlet that air inlet and the cover plate at described hopper 10 top of tubular shell 24 lower end are provided with is communicated with, packing plate 26 is evenly equipped with multiple connection described on, the pneumatic silencer 22 of cavity of resorption, the air inlet of pneumatic silencer 22 is communicated with cavity of resorption 25, exhaust outlet is communicated with epicoele 27, packing plate 26 is provided with installing hole, pneumatic silencer is inserted in installing hole, and by fastening swivel nut 23, each pneumatic silencer is fixedly mounted on packing plate.
In addition, protective cover 21 is added above the upper end exhaust outlet of tubular shell 24, and this protective cover 21 is that size becomes large taper protective cover gradually from the top down, the circumferential edge of protective cover 21 is positioned at the outside of the circumferential edge of described tubular shell 24, leaves the exhaust passage be communicated with the exhaust outlet of described tubular shell 24 between protective cover 21 and tubular shell 24.
During concrete assembling, directly the packing plate being provided with multiple pneumatic silencer directly can be weldingly fixed in tubular shell, then tubular shell is directly weldingly fixed on the cover plate at hopper top, and the gas outlet that the air inlet of tubular shell lower end and hopper top blind flange are provided with is docked and connected.
During use, by auger conveyor 30, powder carry is entered hopper 10, gas in hopper 10 enters in the cavity of resorption 25 of tubular shell 24, mix and have the gas of dust to enter in epicoele 27 after pneumatic silencer 22 filters, then drain through exhaust passage, dust is filtered absorption by pneumatic silencer 22, can not pollute to ambient atmosphere.Due to pneumatic silencer, self to have venting capability good and filter good airproof performance to molecule, can effectively prevent dust from overflowing, guarantee hopper inside and outside air pressure balance.When injecting powder in hopper, air in hopper can be sent rapidly through dust-proof air-breather, the result causing bucket internal gas pressure to raise and then dust is overflowed by force from the soft cloth bag junction between auger conveyor and hopper because gas discharge is obstructed can not be caused, improve working environment.
Pneumatic silencer in above-described embodiment directly can adopt pneumatic silencer conventional in prior art, or directly adopts outsourcing piece.
In above-described embodiment, tubular shell upper end is provided with protective cover, protection can be formed to silencer-filter and tubular shell like this, in other embodiments, if external environment is talked about preferably, also can save protective cover.
In above-described embodiment, the cross section of tubular shell is circular, in other embodiments, also can according to actual needs the design of the cross section of tubular shell be square or other shapes, the dust-proof air-breather of different size type, only need the number of the pneumatic silencer of corresponding increase and decrease, design and produce all more for convenience.
In above-described embodiment, tubular shell directly welds and sets firmly on the cover board, in other embodiments, support also can be set in addition to support fixing tubular shell, be communicated with as long as can ensure that the air inlet of tubular shell lower end is corresponding with the gas outlet in hopper top blind flange.
