Abstract
The utility model discloses a spherical heat accumulator which comprises an upper sphere, a lower sphere and a platform body section. The platform body section is arranged between the upper sphere and the lower sphere. The center positions of the upper sphere, the lower sphere and the platform body section are provided with center through holes which are big-end-down conical center through holes, the center through holes penetrate through the upper sphere, the lower sphere and the platform body section along the center axis, and the top of the upper sphere and the bottom of the lower sphere are provided with small planes. The spherical heat accumulator overcomes the defects in the prior art, can effectively relieve adhesion between the spheres, prolongs the service life, effectively reduces the number of times of changing the spheres, and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of regenerative apparatus, particularly a kind of for the spherical heat storage on hotblast stove or regenerative apparatus.
Background technology
The industries such as present steel chemical industry need the heat storage of many types, general hotblast stove all uses checker brick as heat storage, pebble stove uses spherical heat storage, the heat-accumulating burner great majority of the recuperative heater of rolling system are also used spherical heat storage, by follow-up study for many years, find, when using spherical heat storage fully, hot strength deficiency due to the mutual extruding between ball and ball and refractory materials itself, adding a lot of spherical heat storages is not mechanical compaction, and the reason such as own vol density deficiency, will make in use for some time to be adhered between ball and ball, cause hold over system ventilation property variation, cause thermal storage equipment to have to stop using, changed the shuttle, this not only can affect production, also cause the frequent maintenance of equipment, cause the rising of production cost, therefore affect Business Economic Benefit.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of spherical heat storage, this utility model has overcome the deficiency of existing design, can effectively slow down being adhered between ball and ball, the work-ing life of having improved heat storage, effectively reduce the number of times of changing the shuttle, improved the working efficiency of thermal storage equipment.
For solving the problems of the technologies described above, a kind of spherical heat storage of the utility model, comprise upper sphere, lower sphere and stage body section, described stage body section is arranged between upper sphere and lower sphere, described upper sphere, lower sphere and stage body Duan De center are provided with central through hole, described central through hole is along central axis through upper sphere, between lower sphere and stage body section, and the top of described upper sphere and the bottom of lower sphere all arrange facet.
Described central through hole is up-small and down-big conical centre's through hole.
The beneficial effects of the utility model are:
1, a kind of spherical heat storage of the utility model, profile is designed to non-positive circle, this configuration design Mould Machining manufacture easy to use on the one hand, be easy to the demoulding, can slow down being adhered between ball and ball on the other hand, extend the work-ing life of heat storage, can effectively reduce the number of times of changing the shuttle, improved the working efficiency of thermal storage equipment.
2, this spherical heat storage middle with hole, not only can increase the heating surface of spherical heat storage, and can increase the ventilation property of hold over system.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
In figure: 1-upper sphere, 2-lower sphere, 3-stage body section, 4-central through hole, 5-facet.
Embodiment
As shown in Figure 1 and Figure 2, a kind of spherical heat storage of the utility model, it comprises upper sphere 1, lower sphere 2 and stage body section 3, described stage body section 3 is arranged between upper sphere 1 and lower sphere 2, the center of described upper sphere 1, lower sphere 2 and stage body section 3 is provided with central through hole 4, described central through hole 4 is along central axis through upper sphere 1, between lower sphere 2 and stage body section 3, and the bottom of the top of described upper sphere 1 and lower sphere 2 all arranges facet 5.
As optimization, described central through hole 4 is up-small and down-big conical centre's through hole.So design, can increase the heating surface of spherical heat storage, strengthen the ventilation property of hold over system, also facilitate the heat storage that the pressing machinery press strengthi is higher, thereby extend the work-ing life of spherical heat storage simultaneously.
This spherical heat storage adopts the configuration design of non-complete sphere, design with respect to the spherical heat storage of complete sphere, manufacture on the one hand more convenient, the intensity of heat storage obviously improves, can slow down being adhered between ball and ball on the other hand, improve to a certain extent the work-ing life of heat storage.
Except the described technical characterictic of above-mentioned specification sheets, be the known technology of those skilled in the art.
Claims (2)
1. a spherical heat storage, it is characterized in that, comprise upper sphere, lower sphere and stage body section, described stage body section is arranged between upper sphere and lower sphere, described upper sphere, lower sphere and stage body Duan De center are provided with central through hole, described central through hole is along central axis through upper sphere, between lower sphere and stage body section, and the top of described upper sphere and the bottom of lower sphere all arrange facet.
2. a kind of spherical heat storage as claimed in claim 1, is characterized in that, described central through hole is up-small and down-big conical centre's through hole.
