Dingan County fills a second pipe, offsets between second pipe and first pipe, and the junction of second pipe and first pipe is cased with one
Connector sleeve, connector sleeve are connect with the first, second pipeline thread, and an exhaust pipe is fixedly mounted on the exhaust end of aspiration pump, exhaust
On the right side of pipe with deposit gas tank and be fixedly connected.
One first annulus is fixedly mounted inside second pipe as a preferred technical solution, one is equipped on the left of the first annulus
A filter screen is fixedly mounted in second annulus, the second annulus inside.
The supporting rod of " L " type is also fixedly mounted on the right side of cover body as a preferred technical solution, peace is fixed in supporting rod lower end
Fill a bottom plate.
Cover body and shell are made of transparent plastic material as a preferred technical solution,.
The utility model has the beneficial effects that：The utility model is simple in structure, easy to use, is not destroying and influencing plant
In the case of, the gas that phytovolatilization goes out can be quickly absorbed, and stored.
