Abstract
The invention discloses a kind of method changing flue rotating plate shaft when coke oven is normally produced, comprise the following steps: solid forging flue rotating plate shaft; Clean flues the foreign material at top; The state of flue turnover panel is adjusted to full closure position; Close heating gas, close all waste gases shutter turnover panel; Described flue rotating plate shaft Holder for hanging household utensiles is tied down with wireline; Described flue turnover panel is hung out with chain block; Remove original flue rotating plate shaft; Be screwed on described flue turnover panel by described flue rotating plate shaft, the flue turnover panel of new assembling of slinging slowly puts into flue; Described flue rotating plate shaft is imported in the positioning seat of stack base, completes the replacing of described flue rotating plate shaft.The method is simple and practical, it is convenient to implement, the replacing be not only applicable to when coke oven flue rotating plate shaft goes wrong in normal production is installed, also be applicable to coke oven construction period to be eager due to flue turnover panel floating cargo the installing and using of coke oven flue turnover panel that baker goes into operation, at coking industry, there is reference.
Description
Technical field
The present invention relates to a kind of method that flue rotating plate shaft is changed, particularly relate to a kind of method changing flue rotating plate shaft when coke oven is normally produced.
Background technology
Flue be in coke oven production process produce unique passage that heat exhaust gases discharges, flue turnover panel is the visual plant regulating coke oven flue suction.When the construction period of coke oven carries out the installation of flue turnover panel, the inside and outside personnel of flue coordinate contraposition, make rotating plate shaft enter stack base pilot hole smoothly.Flue turnover panel in the normal productive process of coke oven, is no longer safeguarded the flue rotating plate shaft in flue and changes installation after installing acceptance(check).Main cause is because in production process, be full of the high-temperature flue gas of about 300 DEG C in flue, flue internal pressure is-330 ~-400Pa, and personnel cannot enter in flue and carry out contraposition installation.
In prior art, when flue rotating plate shaft breaks down, if flue rotating plate shaft is butt-welding fitting, butt welding position can be caused in use to snap the potential safety hazard of fracture, for avoiding the expansion of accident risks, the flue turnover panel entirety be in normal production must be hung out, change rotating plate shaft, then flue turnover panel is installed.Carry out closely contraposition installation because personnel cannot enter flue, flue rotating plate shaft cannot be changed.
Summary of the invention
The object of the present invention is to provide a kind ofly do not affect production, the method that flue rotating plate shaft changed when normally producing by practicable coke oven.
For achieving the above object, the technical scheme that the present invention takes is:
Change a method for flue rotating plate shaft when coke oven is normally produced, comprise the following steps:
Steps A: the flue rotating plate shaft that comprises spindle nose, axis body, axle tail and cone is processed in solid forging;
Step B: foreign material, asbestos twine around the flue open holes at the top that cleans flues;
Step C: the state of flue turnover panel is adjusted to full closure position;
Step D: close heating gas, stops coke oven heating, closes all waste gases shutter turnover panel, opens flue inspection window and imports air, reduce flue suction force;
Step e: unclamp the screw on flue rotating plate shaft Holder for hanging household utensiles, ties down described flue rotating plate shaft Holder for hanging household utensiles with wireline, finds center, vertical when making to sling;
Step F: the distance all around regulating described flue turnover panel with steel pipe, makes its both sides consistent apart from the gap of flue lining, hangs out described flue turnover panel with chain block;
Step G: remove original flue rotating plate shaft;
Step H: described flue rotating plate shaft is screwed on described flue turnover panel, the flue turnover panel of new assembling of slinging, slowly puts into flue; Described flue rotating plate shaft is imported in the positioning seat of stack base, completes the replacing of described flue rotating plate shaft.
The method of flue rotating plate shaft is changed when coke oven provided by the invention is normally produced, the method is simple and practical, it is convenient to implement, the replacing be not only applicable to when coke oven flue rotating plate shaft goes wrong in normal production is installed, also be applicable to coke oven construction period to be eager due to flue turnover panel floating cargo the installing and using of coke oven flue turnover panel that baker goes into operation, at coking industry, there is reference.
Accompanying drawing explanation
Fig. 1 is the structural representation of flue rotating plate shaft.
Fig. 2 is one-piece construction schematic diagram of the present invention.
In figure: 1-flue rotating plate shaft Holder for hanging household utensiles, 2-flue turnover panel, 3-flue rotating plate shaft, 4-positioning seat, 5-flue lining, 6-flue open holes, 7-spindle nose, 8-axis body, 9-axle tail, 10-cone.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Change the method for flue rotating plate shaft when coke oven provided by the invention is normally produced, comprise the following steps:
1. as shown in Figure 1, the flue rotating plate shaft 3 that one comprises spindle nose 7, axis body 8, axle tail 9 and cone 10 is processed in solid forging, the right cylinder diameter of axle of axle tail 9 is φ 70mm, length is 180mm, the diameter of axle of cone 10 is φ 70mm, is highly 60mm, cone 10 is convenient to flue rotating plate shaft 3 contraposition smoothly, imports in the positioning seat 4 of stack base.
2. clean flues top flue open holes 6 around foreign material, asbestos twine, prevent foreign material from falling in flue.
3. the state of flue turnover panel 2 is adjusted to full closure position, be convenient to flue turnover panel 2 and hang out from flue open holes 6.
4. close heating gas, stop coke oven heating, close all waste gases shutter turnover panel, open flue inspection window and import air, reduce flue suction force.Avoid as far as possible and to reduce in Renewal process flue turnover panel 2 to the skew of chimney side.
5. as shown in Figure 2, unclamp the screw on flue rotating plate shaft Holder for hanging household utensiles 1, tie down flue rotating plate shaft Holder for hanging household utensiles 1 with wireline, find center, vertical when making to sling.
6. with length be 3500mm, diameter is the distance all around that the steel pipe of φ 50mm regulates flue turnover panel 2, make its both sides consistent apart from the gap of flue lining 5, be about 50mm, hang out flue turnover panel 2 with chain block.
7. original flue rotating plate shaft is removed.
8. be screwed on flue turnover panel 2 by flue rotating plate shaft 3, the flue turnover panel of new assembling of slinging, slowly puts into flue.Because the pilot hole on positioning seat 4 is φ 75, become the cone of φ 10 bottom rotating plate shaft from the right cylinder of φ 70, assemblage gap increases to 60mm by original 5mm, thus forms the Large space installed.With length be 3500mm, diameter is that the steel pipe of φ 50mm props up adjustment flue turnover panel 2, utilize the Large space between cone bottom flue rotating plate shaft 3 and positioning seat 4, flue rotating plate shaft 3 is imported in positioning seat 4, like this, the replacing of flue rotating plate shaft 3, to install.
Above-described is only preferred embodiment of the present invention, does not limit to the present invention.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the present invention, other equivalent modifications and improvement can also be made, all can realize object of the present invention, all should be considered as protection scope of the present invention.
