Abstract
The invention discloses a sealing structure of a rotating sealing valve inspection manhole. The sealing structure of the rotating sealing valve inspection manhole comprises an inspection manhole body (1) and an inspection manhole cover board (2). The inspection manhole cover board (2) is firmly connected with the inspection manhole body (1) through fastening bolts (3) and a sealing groove (4) is formed in the inspection manhole body (1); a sealing protrusion groove (5) is formed in the inspection manhole cover board (2); the sealing groove (4) is matched with the sealing protrusion groove (5). According to the technical scheme, the sealing performance of the rotating sealing valve is good, the inspection efficiency of the inspection manhole of the sealing valve is greatly improved, the structure is simple, and use is convenient.
Description
Technical field
The invention belongs to the technical field of metallurgical industry manufacturing mechanism, relate to coke making process equipment, more particularly, the present invention relates to a kind of maintenance manhole seal structure of rotary seal valve.
Background technique
Dry quenching is a very important link in steel industry coke making process, and dry quenching refers to and adopts inert gas by a kind of method of red burnt cooling down.It has the incomparable advantage of conventional wet quenching at aspects such as improving coke quality, the recycling energy and protection of the environment.
China starts to introduce Dry Quenching Technology from the eighties in 20th century, and this technology is comprehensively applied at present.Dry, put out in process, red Jiao packs into from the dry furnace roof that puts out, low temperature inert gas blasts dry putting out by circulating fan and in stove, absorbs red burnt sensible heat, cooled coke is discharged from the dry furnace bottom that puts out, from the dry stove ring-shaped flue high temperature inert gas out of putting out, by circulating fan, again blast the dry stove that puts out, inert gas recycles in the system of sealing.
Rotary seal valve is important component part in the cold burnt device for transferring of dry quenching unit, it is positioned at the dry furnace bottom that puts out, Main Function is: the cooled coke of quantitatively being discharged by shocking feeder is being sealed dryly put out in stove that recycle gas is not to stove external leakage in the situation that, discharging continuously coke.Rotary seal valve requires tightness good, to meet working condition requirement.
Dry putting out in stove enters foreign matter, in cooling rear discharge process, due to rotary seal valve rotating vane and body clearance little, easily rotation blade is blocked, make coke discharging equipment out of service.If can not recover normal coke discharging in 30 minutes, the dry furnace apparatus that puts out cannot carry out normal dress Jiao and heat exchange work, can cause steam turbine generator by forced-stopping machine, boiler decrease temperature and pressure and steam releasing, and follow-up steam user is forced to stop production.
Dryly put out the harmful poisonous gas (CO, N2) that furnace pressure is about malleation 5000Pa, process foreign matter and need be depressurized to 0Pa, without toxic and harmful, just can enter processing, step-down time length consuming time.
During handling failure, maintainer must dismantle maintenance manhole seal structure of rotary seal valve door, enters valve inner by foreign body, then inspection manhole is sealed.
In the prior art, the project organization complex forms of inspection manhole, is 30 pieces of embedded structures of M18 bolt-locking of periphery, opens and closes the minimum needs of manhole 1 hour, and primary fault is processed needs 2 hours, has a strong impact on the stable operation that dry quenching is produced.
Summary of the invention
The invention provides a kind of maintenance manhole seal structure of rotary seal valve, its objective is the overhaul efficiency that improves rotary seal valve.
To achieve these goals, the technological scheme that the present invention takes is:
Maintenance manhole seal structure of rotary seal valve of the present invention, comprises inspection manhole body, inspection manhole cover plate, and described inspection manhole cover plate is fastenedly connected by clamping bolt and inspection manhole body, and described inspection manhole body is provided with sealed groove; Described inspection manhole cover plate is provided with sealing tongue; Described sealed groove forms and coordinates with sealing tongue.
Described sealed groove and sealing tongue are ring seal structure.
Described sealed groove and sealing tongue are divided into inside and outside two.
The present invention adopts technique scheme, makes the favorable sealing property of rotary seal valve, and the overhaul efficiency of inspection manhole seal valve improves greatly, and it is simple in structure, easy to use.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this specification and the mark in figure are briefly described:

In figure, be labeled as:
1, inspection manhole body, 2, inspection manhole cover plate, 3, clamping bolt, 4, sealed groove, 5, sealing tongue.
Embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technological scheme.
Structure of the present invention, is a kind of maintenance manhole seal structure of rotary seal valve as shown in Figure 1 and Figure 2, comprises inspection manhole body 1, inspection manhole cover plate 2, and described inspection manhole cover plate 2 is fastenedly connected by clamping bolt 3 and inspection manhole body 1.
In order to solve the problem of prior art existence and to overcome its defect, realize the goal of the invention of the overhaul efficiency that improves rotary seal valve, the technological scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, maintenance manhole seal structure of rotary seal valve of the present invention, described inspection manhole body 1 is provided with sealed groove 4; Described inspection manhole cover plate 2 is provided with sealing tongue 5; Described sealed groove 4 forms and coordinates with sealing tongue 5.
Technique scheme of the present invention, improves the overhaul efficiency of inspection manhole seal valve greatly, has therefore improved manufacturing efficiency, has guaranteed the stable operation that dry quenching is produced.
Described sealed groove 4 and sealing tongue 5 are ring seal structure.This makes whole sealing configuration complete, improves sealing effect.
Described sealed groove 4 and sealing tongue 5 are divided into inside and outside two.
The favorable sealing property of above-mentioned rotary seal valve, it is simple in structure, easy to use.By said structure, guaranteed the sealing effect of rotary seal valve, make to operate more convenient simultaneously.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or without improving, design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
