Abstract
The invention provides a grating plate device of an air heating furnace. The grating plate device comprises supporting columns and a grating plate, wherein the grating plate is arranged on the supporting columns; a plurality of holes formed in the grating plate on the supporting faces of the hollow supporting columns are connected with ventilating holes outside the supporting faces of the hollow supporting columns. According to the application, certain holes in the supporting faces of the hollow supporting columns are connected with the adjacent ventilating holes positioned outside the supporting faces of the columns in a manner of horizontal pore channels, so that the problem that the columns block the holes of the supporting grating plate is easily solved, and the structure and the intensity of the supporting grating plate are not influenced; a beam structure is basically omitted, so that any connection between every two supporting grating plate components is avoided; therefore, the structure stress between the supporting grating plate components fixed by a beam in the prior art is also eliminated; the supporting grating plate and the columns are only purely supported with each other without bolt connection; the structure stress between the supporting grating plate and the columns is also eliminated.
Description
Technical field
The present invention relates to the grating plate device that a kind of field of metallurgy hotblast stove or roasting kiln are used.
Background technology
At present most big-and-middle-sized blast funnace hot blast stoves the grating structure of normal use be a kind of grating device of plain base band crossbeam, this grating device technique comparative maturity, its advantage is that the grating manufacturing is simple, checker brick are laid convenient.
A kind of grating device (patent No. CN2066863U) is arranged, cancelled crossbeam, and a kind of grating with stiffening web and pillar have been used, grating is added that stiffening web replaces crossbeam, stiffening web is made regular hexagon makes it can not stop up the grating eyelet, the monolithic grating directly adopts the pillar independent support that adapts with self structure, and the grating bottom matches with the pillar head.Pillar has enough air inlet spaces, ensures that grating and checker brick air-flow are unobstructed.Grating and pillar are 2 absolute construction unit, to increase the heat interchanging area of hotblast stove, improve the heat exchange efficiency of hotblast stove.The advantage of this device is to have cancelled the crossbeam that complex structure, weight are big, stop up the grating eyelet, namely eliminated the defective that structural stress that crossbeam brings is difficult to eliminate, and increases the heat interchanging area of hotblast stove again, improves the heat exchange efficiency of hotblast stove.
The major defect of above-mentioned grating device is to have increased the grating manufacture difficulty, has also increased the weight of monolithic grating.Because in the grating shape more complicated near the furnace shell position, its reinforcing rib structure is corresponding complexity also.And this device is not done substantial improvements for the transition grate piece (being spreader plate) above the grating.
Summary of the invention
At problems of the prior art, an object of the present invention is to provide a kind of grating device that does not have the crossbeam independent support, this grating plate can be eliminated the structural stress that produces during the long-time running of grating device, eliminating pillar stops up the grating eyelet, improve grating leg space ventilation efficient, improve the reliability of grating device and the intensity of grating, repair interval between prolongation.In order to realize this purpose, technical scheme of the present invention is as follows:
A kind of hotblast stove grating plate device, comprise pillar stiffener and grating, described grating is arranged on the pillar stiffener, it is characterized in that, described pillar stiffener is hollow, be arranged in several eyelets of the grating of hollow support post bearing surface top, be connected with penetrating eyelet outside being arranged in hollow support post stayed surface.
Described grating bottom has that a diameter matches with the pillar bearing surface with the degree of depth, vertical with the penetrating eyelet of grating mounting face.
Be positioned at the eyelet of hollow support post bearing surface top on the described grating, be connected with the adjacent pillar stiffener bearing surface penetrating eyelet in addition that is positioned at the form of horizontal hole.
The cross-sectional area of described horizontal hole is not less than 90% of the penetrating eyelet section area of grating.
The present invention has following technique effect:
1, some is positioned at the eyelet of hollow support pillar bearing surface top, be connected with the adjacent penetrating eyelet that is positioned at beyond this root pillar bearing surface with the form of horizontal hole, thereby solved pillar very simply and stopped up the problem that supports the grating eyelet, do not had influence on the structure and the intensity that support grating again.
, fundamentally cancelled beam structure, this makes each support between the grating assembly and does not apply any connection, thereby also eliminated in the past structural stress between the support grating assembly that is fixed together by crossbeam, support and to have only simple supporting role between grating and the pillar and non-bolt is connected, thereby also eliminated the structural stress between support grating and the pillar.

One-piece construction figure in Fig. 1-embodiment of the invention 1;
Eyelet connection diagram in Fig. 2-embodiment of the invention 1;
Embodiment
Below with reference to appended accompanying drawing a preferred embodiment of the present invention is described.
Embodiment 1
That Fig. 1 and Fig. 2 show is first embodiment of grating device, a kind of hotblast stove grating plate device, comprise pillar stiffener 1 and grating 2, described grating 2 is arranged on the pillar stiffener 1, it is characterized in that, described pillar stiffener 1 is hollow, is arranged in several eyelets 3 of the grating 2 of hollow support post 1 bearing surface top, is connected with penetrating eyelet outside being arranged in hollow support post 1 stayed surface.
That a diameter matches with the pillar bearing surface with the degree of depth, vertical with the penetrating eyelet of grating mounting face is arranged at described grating 2 bottoms.
Be positioned at the eyelet 3 of hollow support post 1 bearing surface top on the described grating 2, be connected with the adjacent pillar stiffener bearing surface penetrating eyelet in addition that is positioned at the form of horizontal hole 4.
The cross-sectional area of described horizontal hole is not less than 90% of the penetrating eyelet section area of grating.
For the person of ordinary skill in the field, along with the development of technology, the present invention's design can realize by different way.Embodiments of the present invention are not limited in embodiment described above, and can change within the scope of the claims.
