Abstract
<b> the present invention proposes a kind of hot-air stove grate panel assembly, comprise pillar stiffener and grating, described grating is arranged on pillar stiffener, be arranged in several eyelets of the grating above hollow support post bearing surface, be connected with the penetrating eyelet be arranged in outside hollow support post stayed surface.Application of the present invention, some are positioned at the eyelet above hollow support pillar support face, be connected with the adjacent penetrating eyelet be positioned at beyond this root pillar support face with the form of horizontal hole, from the problem solving pillar blocking support grating eyelet very simply, do not have influence on again the structure and intensity that support grating.Fundamentally eliminate beam structure, this makes not apply any connection between each support grating assembly, thus the structural stress between the support grating assembly that is in the past fixed together by crossbeam is also eliminated, support and between grating and pillar, to only have simple supporting role and non-bolted joint, thus also eliminate the structural stress supported between grating and pillar.</b>
Description
Technical field
the present invention relates to the grating plate device of a kind of field of metallurgy hotblast stove or roasting kiln.
Background technology
the grating structure that the big-and-middle-sized blast funnace hot blast stove of current majority the most often uses is a kind of grating device of plain base band crossbeam, this grating device technique comparative maturity, and its advantage is that grating manufacture is simple, and checker brick are laid convenient.
there is a kind of grating device (patent No. CN2066863U), eliminate crossbeam, and employ a kind of grating with stiffening web and pillar, grating is added stiffening web replaces crossbeam, stiffening web makes regular hexagon makes it can not block grating eyelet, monolithic grating directly adopts the pillar independent support adapted with self structure, matches bottom grating with prop headers.Pillar has enough inlet gaps, ensure grating and checker brick air-flow unobstructed.Grating and pillar are 2 separate building blocks, to increase the heat interchanging area of hotblast stove, improve the heat exchange efficiency of hotblast stove.The advantage of this device eliminates that complex structure, weight are large, the crossbeam of blocking grating eyelet, namely eliminates the defect that structural stress that crossbeam brings is difficult to eliminate, increase again the heat interchanging area of hotblast stove, improve the heat exchange efficiency of hotblast stove.
the major defect of above-mentioned grating device is to add grating manufacture difficulty, too increases the weight of monolithic grating.Because complicated at the grating shape matching near furnace shell position, its reinforcing rib structure is corresponding complexity also.And this device is for the transition grate block (i.e. spreader plate) above grating, do not do substantial improvements.
Summary of the invention
for problems of the prior art, an object of the present invention is to provide a kind of grating device without crossbeam independent support, the structural stress that this grating plate produces during can eliminating the long-time running of grating device, eliminate pillar to block grating eyelet, improve grating leg space ventilation efficiency, improve the reliability of grating device and the intensity of grating, between prolongation, repair interval.In order to realize this object, 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 pillar stiffener, it is characterized in that, described pillar stiffener is hollow, be arranged in several eyelets of the grating above hollow support post bearing surface, be connected with the penetrating eyelet be arranged in outside hollow support post stayed surface.
that a diameter matches with pillar support face with the degree of depth, vertical with the penetrating eyelet of grating mounting face is arranged at described grating bottom.
described grating is positioned at the eyelet above hollow support post bearing surface, is connected with the adjacent penetrating eyelet be positioned at beyond pillar stiffener bearing surface with 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 are positioned at the eyelet above hollow support pillar support face, be connected with the adjacent penetrating eyelet be positioned at beyond this root pillar support face with the form of horizontal hole, thus solve the problem that pillar blocking supports grating eyelet very simply, do not have influence on again the structure and intensity that support grating.
, fundamentally eliminate beam structure, this makes not apply any connection between each support grating assembly, thus the structural stress between the support grating assembly that is in the past fixed together by crossbeam is also eliminated, support and between grating and pillar, to only have simple supporting role and non-bolted joint, thus also eliminate the structural stress supported between grating and pillar.
Accompanying drawing explanation
by the description carried out embodiments of the invention below in conjunction with accompanying drawing, technical scheme of the present invention and technique effect thereof will become clearly, and easy to understand more.Wherein:
one-piece construction figure in Fig. 1-embodiment of the present invention 1;
eyelet connection diagram in Fig. 2-embodiment of the present invention 1;
Embodiment
below with reference to appended accompanying drawing, a preferred embodiment of the present invention is described.
embodiment 1
what Fig. 1 and Fig. 2 showed 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 pillar stiffener 1, it is characterized in that, described pillar stiffener 1 is hollow, is arranged in several eyelets 3 of the grating 2 above hollow support post 1 bearing surface, is connected with the penetrating eyelet be arranged in outside hollow support post 1 stayed surface.
that a diameter matches with pillar support face with the degree of depth, vertical with the penetrating eyelet of grating mounting face is arranged at described grating 2 bottom.
described grating 2 is positioned at the eyelet 3 above hollow support post 1 bearing surface, is connected with the adjacent penetrating eyelet be positioned at beyond pillar stiffener bearing surface with 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 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.
