Description
Technical field
The utility model relates to a kind of bracing or strutting arrangement, specifically belongs to a kind of bracing or strutting arrangement for coke dry quenching furnace annular passage.
Background technology
According to statistics, domestic have the dry coke quenching auxiliary that approaches 200 covers at present, most scales in 140t/h left and right.Wherein largestly can reach 260t/h.Along with the development of coke dry quenching furnace, bring coke dry quenching furnace the furnace lining problem in work-ing life, especially annular passage thereupon, owing to bearing the impact of high-temperature gas and hot coke, cause having pressure reduction to exist inside and outside stove, therefore there is every year the accident that ring-shaped flue collapses to produce.Analyzing its reason, is mainly that stress concentration causes, if adopt half partition wall, while there is distortion, easily wall is supported collapse and stops up chute inlet mouth, also easily supports the annular passage interior wall that collapses, discontinuity simultaneously.
Through retrieval: the patent documentation that Chinese Patent Application No. is CN200910219854.8, it discloses a kind of annular passage with new texture and chute dryly puts out the device that stove comprises annular passage interior wall, chute, and its structure is that annular passage interior wall is suspended structure.Annular passage interior wall is composited by suspending cooling cylinder, refractory brick, mould material and lagging material, suspending cooling cylinder is hung interior wall entirety in the metal construction of furnace shell, the arranged outside refractory brick of annular passage interior wall, central authorities are cooling cylinders, between refractory brick and cooling cylinder, lagging material is set, annular passage interior wall bottom arranges mould material.Beneficial effect is: annular passage interior wall is designed to suspended structure, its weight is not directly born by chute dividing wall, eliminated the destruction of annular passage interior wall to chute, thereby extended dry work-ing life of putting out stove.But its support is also brick structure, and support strength is inadequate, and complex structure, distinguished and admirable in annular passage is connected with to certain influence; Change the flow direction of hot blast in annular passage, made red Jiao's cooling performance variation.
Chinese Patent Application No. is the patent documentation of CN200910219858.6, it discloses a kind of new texture dryly puts out the dry stove that puts out that stove relates to a kind of new texture, comprise cooling room, oblique flue, annular passage and the chamber that prestores, it is characterized in that, cooling room diameter is identical with the chamber diameter that prestores, tiltedly the inner extension supporting of flue; Horizontal support is set in annular passage, is provided with half high knee wall.Compared with prior art, the invention has the beneficial effects as follows: furnace binding is simple, rational in infrastructure firm, greatly improved the intensity of belt air channel and oblique mid-feather, avoid collapsing in process of production, reduce the dry maintenance workload that puts out stove, extend dry work-ing life and the life cycle of putting out stove.But it is also brick structure, and support strength is inadequate, but also change the flow direction of annular passage apoplexy, made red Jiao's cooling performance variation.
Utility model content
The problem that the purpose of this utility model is to overcome easily distortion of coke dry quenching furnace annular passage that prior art exists, bulging, collapses, provide a kind of by improving its force structure, what prevent that coke dry quenching furnace annular passage from causing by being out of shape collapses, improve life cycle, and the bracing or strutting arrangement for coke dry quenching furnace annular passage simple in structure.
Realize the technical measures of above-mentioned purpose:
For a bracing or strutting arrangement for coke dry quenching furnace annular passage, it is: it comprises back up pad, be connected in back up pad one side and the interior wall web plate that matches with interior wall shape, be connected in back up pad opposite side and the exterior wall web plate, the back up pad that match with exterior wall shape are provided with the connecting hole that is respectively equipped with at least two ventilation holes, interior wall web plate and exterior wall web plate, are connected in the cast bed of material on back up pad and interior wall web plate and exterior wall web plate.
It is characterized in that: on back up pad and interior wall web plate and exterior wall web plate, be connected with anchoring piece.
It is characterized in that: between back up pad and interior wall web plate and exterior wall web plate, be connected with respectively stiffening web.
Feature of the present utility model is: support strength is high, can effectively reduce the expansion of annular passage liner, the destruction of opposing stress, reduce production maintenance cost, be beneficial to that to protect the production of coke-oven plant's coke dry quenching furnace stable, and on the air quantity in annular passage without impact, simple in structure, easily implement.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-back up pad, 2-interior wall web plate, 3-exterior wall web plate, 4-ventilation hole, 5-connecting hole, 6-cast bed of material, 7-anchoring piece, 8-stiffening web.
Embodiment
Be described further below in conjunction with accompanying drawing:
A kind of bracing or strutting arrangement for coke dry quenching furnace annular passage: it comprises back up pad 1, adopt welding or bolt to connect the interior wall web plate 2 matching with back up pad 1 one sides and with interior wall shape, the exterior wall web plate 3 that adopts welding or bolt to be connected in back up pad 1 opposite side and to match with exterior wall shape, at least two ventilation holes 4 of processing in back up pad 1, the connecting hole 5 of processing respectively on interior wall web plate 2 and exterior wall web plate 3, employing is welded to connect the cast bed of material 6 on back up pad 1 and interior wall web plate 2 and exterior wall web plate 3.In back up pad 1, the pore size of at least two ventilation holes 4 of processing or number are all determined according to the size of air quantity.In order to increase the firmness of the cast bed of material 6, on back up pad 1 and interior wall web plate 2 and exterior wall web plate 3, be welded with anchoring piece 7, and be welded with respectively stiffening web 8 between back up pad 1 and interior wall web plate 2 and exterior wall web plate 3.
When the utility model is installed, in annular passage, arrange symmetrically.
When use, interior wall web plate 2 is installed on to the interior walls in air channel to application, exterior wall web plate 3 correspondences is installed on to the external wall in air channel, and is all fixed by the bolt in connecting hole 5.
Above-described embodiment only exemplifies for the best, and is not the restriction to embodiment of the present utility model.
