Description
Technical field
The utility model relates to camera lens field, particularly relates to a kind of lens adapter for slr camera.
Background technology
The basic reason of coking be ash deposition under molten state on heating surface, leak out relevant with injection angle of burners, firing optimization, boiler plant.Fusion point of ash is the key of coking.Coking can cause overheating steam temperature to raise, and cause overheating steam temperature, reheat steam temperature desuperheating water opens greatly, even can cause the explosion of carbonated drink pipe; Coking can make boiler output reduce, and causes and be forced to blowing out time serious; Coking can shorten the serviceable life of boiler plant; Flue gas loss increases, and boiler efficiency reduces; Induced draft fan consumes power increases; Because coking is uneven often, thus water-cooling wall slagging scorification can bring adverse effect to the water-flow circulation safety of natural circulation boiler and the thermal deviation of forced circulation boiler water-cooling wall.
Coking easily becomes lime-ash bulk, makes dragveyer, slag crusher transport difficult, sometimes overload trip, makes slag runner blocking time serious, and load down of having to runs.If when coking fuses into bulk, because gravity falls from top, cause smashing furnace hopper water-cooling wall.Underload can cause unstable combustion even flame-out because falling large lump coke.If when causing the whole coking of water-cooling wall, only have blowing out to carry out artificial coke cleaning.
So operating personnel sometimes need to observe the working condition in stove in time, generalized case can adopt visual inspection, but so not only easily injured, is also not easy to observe clear; Single-lens reflex camera at ordinary times in our life is generally all used to shooting landscape or personage, if apply in kiln field by the function of slr camera high definition imaging, can have greatly improved effect.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of lens adapter for slr camera, structure is simple, one end can be connected with the camera lens of slr camera, the other end can be connected with blast furnace detection instrument, observe the working condition of high furnace interior by slr camera after combination, utilize the function of slr camera high-resolution imaging, clearly can observe the working condition in blast furnace.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of lens adapter for slr camera, comprise lens barrel main body, the two ends of described lens barrel main body are respectively equipped with primary mirror hole and secondary mirror hole, the inwall in described primary mirror hole and secondary mirror hole is provided with connecting thread, the middle part surface of described lens barrel main body is carved with antiskid thread layer, and described primary mirror hole and inside, secondary mirror hole are provided with eyeglass.
In the utility model preferred embodiment, the material of described lens barrel main body is stainless steel.
In the utility model preferred embodiment, the surface of described lens barrel main body scribbles corrosion protection paint.
In the utility model preferred embodiment, the diameter of described lens barrel main body middle-end and the diameter of two side ends not reciprocity.
The beneficial effects of the utility model are: a kind of lens adapter for slr camera of the utility model, structure is simple, one end can be connected with the camera lens of slr camera, the other end can be connected with blast furnace detection instrument, observe the working condition of high furnace interior by slr camera after combination, utilize the function of slr camera high-resolution imaging, clearly can observe the working condition in blast furnace.
