Abstract
The utility model discloses a grating plate device of a hot-blast furnace. The grating plate device comprises a supporting column and a grating plate, wherein the grating plate is arranged on the supporting column, and a plurality of holes of the grating plate which is arranged above a supporting surface of the hollow supporting column are connected with through holes which are formed outside the supporting surface of the hollow supporting column. According to the grating plate device, the holes positioned above the supporting surface of the hollow supporting column are connected with the adjacent through holes which are positioned outside the supporting surface of the column in the form of a horizontal pore passage, so that the problem that the column blocks the holes of the supporting grating plate is simply solved, and the structure and strength of the supporting grating plate are not affected. A crossbeam structure is fundamentally removed to ensure that any connection is not applied among all supporting grating plate components, so that the structural stress among the supporting grating plate components which are fixed together by a cross beam in the past is eliminated; and only a simple supporting effect is needed between the supporting grating plate and the column without bolted connection, thereby eliminating the structural stress between the supporting grating plate and the column.
Description
Technical field
The utility model relates to the grating plate device that a kind of field of metallurgy hotblast stove or roasting kiln are used.
Background technology
The grating structure that present most big-and-middle-sized blast funnace hot blast stoves the most often use is a kind of grating device of plain base band crossbeam, this grating device technique comparative maturity, and 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 large, stop up the grating eyelet, namely eliminated the defective that structural stress that crossbeam brings is difficult to eliminate, and increases again the heat interchanging area of hotblast stove, 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 complicated at the grating shape matching 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.
The utility model content
For problems of the prior art, a purpose of the present utility model provides a kind of grating device without 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, the technical solution of the utility model 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 utlity model 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 very simply pillar and stopped up the problem that supports the grating eyelet, do not had influence on again the structure and the intensity that support grating.
, fundamentally cancelled beam structure, this does not apply any connection so that each supports between the grating assembly, thereby also eliminated in the past structural stress between the support grating assembly that is fixed together by crossbeam, support between grating and the pillar and only have simple supporting role and non-bolted joint, thereby also eliminated the structural stress that supports between grating and the pillar.
Description of drawings
By the description of embodiment of the present utility model being carried out below in conjunction with accompanying drawing, it is clearer that the technical solution of the utility model and technique effect thereof will become, and easy to understand more.Wherein:
One-piece construction figure among Fig. 1-the utility model embodiment 1;
Eyelet connection diagram among Fig. 2-the utility model embodiment 1;
Embodiment
Below with reference to appended accompanying drawing a preferred embodiment of the present utility model is described.
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 utility model design can realize by different way.Embodiment of the present utility model is not limited in embodiment described above, and can change within the scope of the claims.
