Slot guide is equipped at the two of portion, two strips are installed in respectively at two slot guides, make the sampler bag vertical
In the cross section of the sealing bucket, it is fixedly installed in the sealing bucket.
Further, the sealing barrel side wall is offered with the thief hatch of movable sealing lid and internal pressure control mouth, described
One end that thief hatch is located in the sealing bucket passes through connection flexible pipe and the switch valve mobile communication of the sampler bag.
Further, the strip uses flexible plastic material.
Further, the slot guide includes two truss monomers, and the truss monomer fixation is to being arranged on the sealing bucket
At two madial walls and in same horizontal line.
Further, the sealing bucket is rectangular parallelepiped structure.
Further, it is equipped with handle at the top of the sealing bucket.
The beneficial effects of the utility model are：
1st, the utility model is by adding the strip at sampler bag both ends with adding the slot slot guide at sealing bucket both ends
Cooperation, by sampler bag it is open and flat be fixed on sealing bucket in, avoid sampler bag group epitome ring bag in rate of pressure change, be conducive to carry
High operating efficiency.
2nd, the utility model matches by using the sealing bucket of rectangular parallelepiped structure with vertical open and flat fixed sampler bag, makes
Sealing bucket external volume and internal capacity are reduced, and are conducive to improve portable performance, and further improve sampling operation effect
Rate.
Description of the drawings
Fig. 1 shows the utility model positive structure diagram.
Fig. 2 shows the utility model side structure schematic view.
Fig. 3 shows that the utility model seals bucket overlooking the structure diagram.
Specific embodiment
As shown in Fig. 1 ~ Fig. 3, a kind of Portable stink gas rapid sampler, including the knot identical with existing sampler
Structure：Sampler bag 1 and sealing bucket 2, the sampler bag 1 are movably set in the sealing bucket 2.Sealing 2 side wall of bucket offers
Thief hatch 21 and internal pressure control mouth 22.The thief hatch 21 passes through connection flexible pipe 5 and the 11 gas circuit phase of switch valve of the sampler bag 1
Connection.The internal pressure control mouth 22 is connected with two-way air pump.By regulation and control of the two-way air pump to sealing 2 internal pressure of bucket, make
The sampler bag 1 is being deflated by the thief hatch 21（Manufacture negative pressure）Switch between air-breathing two states, realize the sampling
The cleaning and sampling of bag 1.
The utility model and existing sampler difference lies in：
1 upper/lower terminal of sampler bag is equipped with strip 3, and the strip 3 is installed in respectively to be installed in the sealing bucket 2
Wall is in two slot guides 4 in top and bottom region.By fixation of the slot guide 4 to the strip 3, make described
Sampler bag 1 is perpendicular to the cross section of the sealing bucket 2, open and flat and that stablizes is fixedly installed in the sealing bucket 2, effectively avoids
The reduction for the sampling operation efficiency caused by deformation that the sampler bag 1 occurs due to pressure change in the sealing bucket 2.
The sealing bucket 2 is rectangular parallelepiped structure, is matched with the open and flat fixed sampler bag 1.Rectangular parallelepiped structure compared with
Existing is mostly the sealing shell of cylinder, and exterior space occupancy is smaller, is conducive to improve the portable performance of sampler；Meanwhile
Inner barrel volume also accordingly reduces, and is conducive to the regulation and control for accelerating external air pump to pressure in bucket, improves sampling operation efficiency.
2 top of sealing bucket is equipped with handle 6, easy to carry.
The slot guide 4 include two truss monomers 41, the truss monomer 41 fix to be arranged on it is described sealing bucket 2 two
At madial wall and in same horizontal line.The most long wire length of the two truss monomers 41 of the slot guide 4 is more than
The length of the strip 3, and the shortest route length be less than the strip 3 length, so as to the strip 3 can smoothly block set into
In the slot guide 4, and it is stabilized fixation.
The strip 3 uses flexible plastic material, smoothly to snap fits into the slot guide 4.
Movable sealing lid 23 is equipped at the thief hatch 21 and the internal pressure control mouth 22.After sampling operation is completed,
By the movable sealing lid 23 closed isolation sealing bucket 2, the pressure for reducing the sampler bag 1 and the sealing bucket 2 becomes
Change, be conducive to avoid sample in the sampler bag 1 to leak.
Illustrate that specific embodiment of the present invention is as follows in conjunction with the embodiments：
1. the loading of sampler bag
The bung of the sealing bucket 2 is opened, by the connection flexible pipe 5 and the gas of the switch valve 11 of the sampler bag 1
Road is connected.After opening the switch valve 11, the thief hatch 21 is detected to the connectivity of 1 gas circuit of sampler bag.
The strip 3 of 1 bottom of sampler bag is inserted into the slot guide 4 of 2 bottom of the sealing bucket,
Determine that the strip 3 is arranged in the bottom of the two truss monomers 41.It is stretched to the sampler bag 1 is open and flat close to the sealing
At another slot guide 4 at 2 top of bucket, another strip 3 at 1 top of sampler bag is installed in described in another group
The top of truss monomer 41.
It completes after fixing, closes the sealing bucket 2, adjust the leakproofness of the thief hatch 21 and the internal pressure control mouth 22
Energy.
2. the assembling of sampler
The movable sealing lid 23 at the internal pressure control mouth 22 is opened, is connected into two-way air pump.Open two-way air pump to
Inflation in the sealing bucket 2, is compressed the sampler bag 1, to keep negative pressure in the sampler bag 1.
The movable sealing lid 23 at the thief hatch 21 is opened, is connected into sampling gun.
3. it samples
Sampling gun is stretched into malodor source, two-way air pump is opened and extracts gas in the sealing bucket 2 out, to release to described
The compacting of sampler bag 1 makes gas in malodor source flow through the thief hatch 21 and the switch valve 11 to the sampling from sampling gun
In bag 1.After 10s ~ 20s, open two-way air pump and inflated into the sealing bucket 2, the sampler bag 1 is compressed, by described in
The gas of sampler bag 1 extrudes.It repeats 2 ~ 3 times, completes the cleaning of the sampler bag 1.
Two-way air pump is kept to make the sampler bag 1 abundant extraction state 2min ~ 5min of gas in the sealing bucket 2
Sampling.
After completing sampling, sampling gun is quickly removed from the thief hatch 21, it is closed using the movable sealing lid 23
The thief hatch 21.Two-way air pump is removed from the internal pressure control mouth 22, it is closed described using the movable sealing lid 23
Internal pressure control mouth 22.The sealing bucket 2 is carried to sample storeroom by handle 6.
