Description
Technical field
Metallurgy industry sintering process field is the utility model is related to, especially a kind of sintering flue gas air leak test device.
Background technology
Most of steel enterprise sintering process uses down draft sintering technique at home, so results in main exhauster and is transporting
There is a situation where that power consumption is gradually increasing generation during row, by technical staff's analysis find except raw material variety, granularity change,
Thickness of feed layer change, personnel are operated outside the influences such as horizontal change, and air leakage phenomena is also to cause exhausting between agglomerating plant
The main reason for electromechanics consumption rises, meanwhile, reduction sintering power consumption 1.5kwh/t can be realized by often reducing sintering air leak rate of air curtain 10%.In order to
The influence that sintering leaks out to sintering power consumption is reduced, technical staff proposes that air leak test method is oxygen balance and carbon balance method.But
For realizing that this method do not suggest that corresponding detection device.
Utility model content
To solve the deficiency present in above-mentioned technical problem, the utility model is directed to a kind of easy to operate, testing number
According to accurate sintering flue gas air leak test device.
In order to solve the above technical problems, the utility model adopts the following technical solution：
One kind sintering flue gas air leak test device, including pallet, test sample tube, spy rifle, flue gas analyzer, sinter platform
Mounting hole is provided with the one side of car, exhausting aperture is provided with test sample tube, one end of test sample tube is passed through from mounting hole
And welded with the another side of pallet, the other end of test sample tube is connected by ball valve with visiting one end of rifle, visits the another of rifle
One end is connected by silicone tube with flue gas analyzer.
Compared with prior art, the beneficial effects of the utility model are：
Test sample tube with exhausting aperture is run through pallet by the utility model, can ensure pallet and bellows
Between space uniform exhausting, flue gas analyzer being detected to the flue gas in agglomerating plant promptly and accurately can be utilized, then
Air leak rate of air curtain between pallet and bellows is calculated with reference to air leak test method by detecting data, effectively helps worker timely
Taking reduces the measure of air leak rate of air curtain, reduces sintering power consumption；Using being threadedly coupled between test sample tube, ball valve and spy rifle, ensure each
The junction of part is close not to leak out, and reduces interference of the environmental air to detection data.
Further, the preferred solution of the utility model use is：
The both ends of ball valve are respectively arranged with internal thread, and one end that test sample tube is connected with ball valve is provided with the interior spiral shell with ball valve
The matched test sample tube external thread structure of line；One end that rifle is connected with ball valve is visited to be provided with and the matched spy of ball valve internal thread
Rifle external thread structure.

Embodiment
One kind sintering flue gas air leak test device, by pallet 1, test sample tube 2, visits rifle 4, Portable smoke analysis instrument
6 form, and are provided with mounting hole 7 on the one side of pallet 1, exhausting aperture 8 is provided with test sample tube 2, test sample tube 2
One end passes through from mounting hole 7 and is welded with the another side of pallet 1, by being provided between test sample tube 2 and silicone tube 5
The ball valve 3 of internal thread connects, and test sample tube 2 is provided with and the matched detection of the internal thread of ball valve 3 with one end that ball valve 3 is connected
Sample pipe external thread structure 201, visits rifle 4 and is provided with and the matched spy rifle of the internal thread structure of ball valve 3 with one end that ball valve 3 is connected
External thread structure 401, the other end for visiting rifle 4 are connected by silicone tube 5 with Portable smoke analysis instrument 6.
The setting of exhausting aperture 8 in test sample tube 2, can ensure that the space uniform between pallet 1 and bellows 9 is taken out
Wind.
The junction of test sample tube 2 and ball valve 3, visit rifle 4 and be respectively adopted with the junction of ball valve 3 and is threadedly coupled, and guarantee is respectively
The junction of part is close not to leak out, and reduces interference of the environmental air to detection data, improves the accuracy of data.
The above is only the specific embodiments of the utility model, but the protection not limited to this of the utility model, any skill
The technical staff in art field the thinkable change being equal with the technical program technical characteristic or replacement, all cover in this practicality
Within new protection domain.
