Abstract
The utility model relates to a peeping device for blast furnace tuyere pertaining to iron-smelting technique field. The utility model comprises a tuyere peeping hole body 1 and a drawtube 3 connecting to right end of the same, a peeping hole 4 is arranged in said peeping hole body, a truncated cone shape control valve 2 is arranged on middle of said tuyere peeping hole body, a through hole matching with the peeping hole is arranged on middle of said control valve 2 having a swing handle 5. In normal process, the swing handle 5 on the valve is turned with spanner to make the peeping hole through such that operators may observe the condition inside the furnace via lens conveniently, the passage is cut off by turning the handle with spanner then screw off the drawtube and lens 7 can be changed if needed. The utility model apparatus may make it safe, convenient and no noise for workers to change the lens.
Description
Technical field
The utility model relates to a kind of blast-furnace tuyere with spying on device, belongs to the ironmaking technology field.
Background technology
Device is spied in the air port of iron-smelting blast furnace at present, eyeglass on its peep hole is to be made by simple glass, under the high wind-warm syndrome environment more than 1000 ℃, often cracked, or since the coal dust of winding-up or dust accumulation in the front of eyeglass, therefore the person that influences the blast furnace operating changes the routine work that air port window eyeglass or cleaning hole inside ash have become blast furnace pipe arrangement worker by situation in the direct viewing stove of air port.The existing hole body of spying on of spying on device is one section straight pipe, and pipe end is rotary with lens barrel.There is not following shortcoming in this device in the production use, (1) causes hot blast to blow out the calcination casualty accident easily, and the noise that (2) hot blast blows out generation is big, and (3) make when changing because furnace pressure height and wind-warm syndrome height, and is easy to operate and difficulty is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can cut off the peep hole passage, so that safety is changed the blast-furnace tuyere of eyeglass with spying on device.
The purpose of this utility model is achieved in that
The utility model blast-furnace tuyere is spied on device, form by the lens barrel that blast-furnace tuyere is spied on hole body and is connected its right-hand member, described spying on is provided with peep hole in the hole body, described blast-furnace tuyere is spied on the hole body middle part and is provided with the circular platform type by-pass valve control, described by-pass valve control middle part be provided with one with the through hole of peep hole coupling, have swing handle on the by-pass valve control.
The utility model is when changing eyeglass, and the swing handle on the rotary control valve body cuts off hot-air channel, changes eyeglass then fast.Accomplish the noiseless interference, satisfy the production requirement of safety, environmental protection.
