Abstract
The utility model discloses a tuyere peep hole device for observing the operation condition in metallurgical blast furnace tuyere, a tapered hole 12 is arranged at the center at the bottom surface of cover plate 7, spherical sleeve tube 6 is arranged in the spherical hole of the cover plate 7, cushion plate 4 is arranged at the outer flange of the spherical sleeve tube 6, small gate 5 is adjacent to the cushion plate 4, the center position of the small gate 5 is provided with a tapered hole 13, a valve seat 3 is sleeved at the upper end of the spherical sleeve tube 6 by thread connection method, a valve core 11 is arranged in the valve seat 3, a nut 1 is screwed on the upper end of the valve seat 3, an asbestos cushion 2 and a blue glass 2' is arranged between the nut 1 and the valve seat 3. when the operation condition in the tuyere needs to be observed, the valve core 11 is opened, then the valve seat 3 is rotated to drive the spherical sleeve tube 6 to rotate together, as the tapered hole 12 or 13 exists, the peeping range of tuyere is extended so that the operation condition in the tuyere can be known more completely .
Description
Technical field
The utility model relates to a kind of air port peep hole device that is applied to observe operating mode in the metallurgy high furnace air port.
Background technology
In coal injection process in the metallurgy high furnace stove, all to from the peep hole in air port, observe the situation that is positioned at the air port pulverized coal gun at any time and realize best winding-up effect so that adjust the spray gun position at any time.Exist to regulate at the air port peep hole device of realizing this function before the utility model and spy on angle or can only in very among a small circle, regulate the problem of spying on angle, trace it to its cause is that spherical sleeve pipe adjustable scope of activity in wicket and cover plate is narrow, the hole that spherical sleeve pipe matches with wicket, cover plate is a straight hole, there is very big dead angle, can only among a small circle, spies on the air port.
Summary of the invention
Task to be solved in the utility model provides a kind of modified version air port peep hole device that enlarges operating mode in the air port scope of spying on, the overall understanding air port.
For finishing above-mentioned task, the technical solution adopted in the utility model is: do not change original air port peep hole device main body structure and shape, as cover plate, spherical sleeve pipe, wicket, valve seat etc., only the straight shape hole with the cover plate bottom centre position changes the awl cylindrical hole into, adds a circular or square backing plate that can match with spherical sleeve pipe in spherical telescopic spheroid outer; Change the straight shape hole of wicket central position into awl cylinder shape hole, wicket and backing plate are adjacent; Change the circular blue glass that is put on the valve seat into be convenient to process square blue glass.
Adopt a kind of air port peep hole device that as above technical scheme provides compared with prior art, its beneficial effect is:
1. since spherical sleeve pipe in the central position of cover plate with in the movable range extension of the central position of wicket, operator spy on 2～3 times of range extension to situation in the air port, situation about recognizing is more comprehensive, and the certainty of handling problem and accuracy have improved 2～3 times.
2. be loaded on blue glass between nut and the valve seat and change into squarely, easy to process by circle, save tooling cost and take.
Description of drawings
Fig. 1 is the schematic top view of air port described in the utility model peep hole device.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1, also is specification digest accompanying drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in drawings, described air port peep hole device by nut 1, asbestos pad 2, blue glass sheet 2 ', valve seat 3, backing plate 4, wicket 5, spherical sleeve pipe 6, cover plate 7, handgrip 8, carve plate 9, bearing pin 10, spool 11 and constitute.It is trapezoid awl cylinder shape hole 12 that the bottom center position of cover plate 7 has section, the height in awl cylinder shape hole 12 and angle a=5～15 between the waist °.Spherical sleeve pipe 6 is arranged in the sphere shape hole of cover plate 7 central authorities, and the central axis of spherical sleeve pipe 6 center holes is overlapped with the axial line in awl cylinder shape hole 12.At the top of spherical sleeve pipe 6 outer edge circle or quadrate backing plate 4 are arranged, wicket 5 adjacent backing plates 4, have section in the central position of wicket 5 and be handstand trapezoid awl cylinder shape hole 13, the height in awl cylinder shape hole 13 and angle β=5～15 between the waist °, wicket 5 usefulness bearing pins 10 and carve plate 9 and be positioned on the cover plate 7.Screw thread is connected with valve seat 3 in the upper end of spherical sleeve pipe 6, in the middle part of valve seat 3 spool 11 is installed, and the straight hole on the valve seat 3 can be closed or open to rotational valve core 11.Be screwed with nut 1 in the upper end of valve seat 3, nut 1 and valve seat 3 touching positions have asbestos pad 2 and blue square glass sheet 2 '.During fastening nut 1, asbestos pad 2 can play a part protective glass sheet 2 '.Spy on aperture 14 at the middle position of nut 1, the central axes of spying on clear opening, the clear opening on the spherical sleeve pipe 6 and the awl cylinder shape hole 12 on the cover plate 7 on aperture 14, the valve seat 3 on the nut 1.
During use, make air port described in the utility model peep hole device according to accompanying drawing, and the square opening on cover plate 7 or opening slotted eye link to each other whole device with the peep hole mounting.Rotational valve core 11 makes the clear opening unlatching on the valve seat 3 see light.Operator can be from the nut 1 the situation in the aperture 14 direct viewing blast-furnace tuyeres of spying on.While rotational valve core 3, spool 3 drives in the central sphere shape hole of spherical sleeve pipe 6 on cover plate 7 and rotates, because awl cylinder shape hole 13 and 12 is arranged on wicket 5 and the cover plate 7, can enlarge the slewing area of spherical sleeve pipe 6 on wicket 5, cover plate 7, promptly enlarged the scope of spying on that people observe operating mode in the air port.Backing plate 4 can play the effect of stable spherical sleeve pipe 6 positions.After certain had been spied on, rotational valve core 11 was closed and is spied on aperture.Foreign material in the cleaning cone cylinder shape hole 12 (as scum etc.) or change spherical sleeve pipe 6 or backing plate 4 can unclamp bearing pin 10 and carve plate 9 if desired, move handgrip 8, take off wicket 5 to get final product, and after finishing, reinstall wicket 5, load onto and carve plate 9 or bearing pin 10, come into operation.When not spying on, rotational valve core 11 is closed and is spied on aperture 14.
