Description

Technical Field

[0001] The utility model relates to the field of melting furnaces, in particular to a melting furnace heat storage ball. Background Art

[0002] There are usually multiple heat storage carriers placed inside the furnace, and the existing conventional heat storage carriers are heat storage balls. The multiple heat storage balls in the furnace are placed in the heat storage area and the heat release area respectively. When combustion occurs inside the furnace, the heat in the exhaust flue gas can be stored by the heat storage balls in the heat storage area. Then the heat storage balls in the heat storage area and the heat release area are exchanged. The heat storage balls release heat in the heat release area to heat the combustion-supporting air. The heat storage balls switch back and forth between the heat storage area and the heat release area to improve thermal efficiency. Some existing heat storage balls are provided with a through hole, which can not only increase the heat exchange area, but also facilitate the airflow through the heat storage balls. However, the heat exchange speed of the current heat storage balls is still insufficient, and the resistance to the airflow is still relatively large. Utility Model Content

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 3, a furnace regenerative ball according to an embodiment of the present invention, includes a ball 100, a first through-hole 200, a second through-hole 300, and a third through-hole 400. The first through-hole 200 is provided in the ball 100; the second through-hole 300 is provided in the ball 100; and the third through-hole 400 is provided in the ball 100. The first through-hole 200, the second through-hole 300, and the third through-hole 400 are perpendicular to each other and interpenetrate one another.

[0035] By providing the first through hole 200, the second through hole 300 and the third through hole 400 in the sphere 100, the heat exchange area between the heat storage ball and the air is increased, and the heat exchange speed is improved. Moreover, since the first through hole 200, the second through hole 300 and the third through hole 400 are perpendicular to each other and interconnected, wind flow from all directions can flow to a certain extent with the help of the first through hole 200, the second through hole 300 and the third through hole 400, so that the wind resistance in all directions of the heat storage ball is reduced, thereby significantly reducing the resistance to wind flow.

[0036] In the embodiment, the center point of the sphere 100 is located at the hole axis of the first through hole 200, the center point of the sphere 100 is located at the hole axis of the second through hole 300, and the center point of the sphere 100 is located at the hole axis of the third through hole 400. The above structure, that is, the first through hole 200, the second through hole 300, and the third through hole 400 all pass through the center point of the sphere 100, so that the length of the first through hole 200, the second through hole 300, and the third through hole 400 can be maximized. At this time, the hole wall area of ​​the first through hole 200, the second through hole 300, and the third through hole 400 can be maximized, which is conducive to maximizing the heat exchange area and heat exchange rate of the heat storage ball; and it can also make the sphere 100 relatively evenly divided, which is conducive to balancing the heat conduction thickness of each part of the sphere 100, avoiding the problem of excessive thickness in some parts of the heat storage ball and slow heat storage and heat release.

[0037] It is conceivable that, in other embodiments, the first through hole 200 may not pass through the center point of the sphere 100, the second through hole 300 may not pass through the center point of the sphere 100, and the third through hole 400 may not pass through the center point of the sphere 100; or part of the through hole 200 may pass through the center point of the sphere 100, and the other part may not pass through the center point of the sphere 100, etc. Those skilled in the art can make specific configurations according to actual needs.

[0038] In this embodiment, a fourth through hole 500 is further included. The fourth through hole 500 is spaced apart and parallel to the first through hole 200. The fourth through hole 500 is interconnected with the second through hole 300 or the third through hole 400. The provision of the fourth through hole 500 can further increase the heat exchange area and heat exchange rate of the sphere 100 and further help reduce the wind resistance of the heat storage sphere.

[0039] In this embodiment, four fourth through holes 500 are provided, all of which are evenly arranged around the axis of the first through hole 200. Providing four fourth through holes 500 and evenly distributing them around the first through hole 200 facilitates relatively uniformly improving the heat exchange rate across the thermal storage ball while minimizing the impact on the ball's structural strength. It is contemplated that the number of fourth through holes 500 can also be other, for example, two, three, or more. Those skilled in the art can configure the number of fourth through holes 500 based on practical needs.

[0040] In the embodiment, the first through hole 200, the second through hole 300, the third through hole 400, and the fourth through hole 500 are all circular holes. The circular hole structure of the above-mentioned through holes is conducive to maintaining a high structural strength of the thermal storage ball, balancing the heat conduction thickness of the ball 100 at various locations, and is also conducive to the processing and manufacturing of the thermal storage ball, making the processing relatively convenient.

[0041] In the embodiment, the diameters of the first through hole 200, the second through hole 300, the third through hole 400, and the fourth through hole 500 are the same. Using a circular hole structure with the same diameter is beneficial to reducing the manufacturing complexity of the heat storage ball and facilitating production.

[0042] Furthermore, in this embodiment, the outer diameter of the sphere 100 is 25 mm, and the diameters of the first through hole 200, the second through hole 300, the third through hole 400 and the fourth through hole 500 are 4 mm, and the comprehensive use effect is good; the diameter of the sphere 100 is relatively moderate, and when multiple heat storage balls are stacked, the gap size between different heat storage balls is relatively moderate, and the stacking density is relatively appropriate, reducing the risk of combustion dust clogging the gap; the diameter size of the through hole is relatively moderate, reducing the impact on the structural strength of the heat storage ball, and the effect of reducing the wind resistance of the heat storage ball and increasing the heat exchange speed is relatively obvious.

[0043] It is understandable that in other embodiments, the outer diameter of the sphere 100 can also be other sizes, and those skilled in the art can specifically configure it according to actual needs; the diameters of the first through hole 200, the second through hole 300, the third through hole 400 and the fourth through hole 500 can also be other sizes, and those skilled in the art can specifically configure it according to actual needs.

[0044] In the embodiment, a connecting hole 600 is further included, with both ends of the connecting hole 600 respectively connected to the first through hole 200 and the fourth through hole 500. The connecting hole 600 is located inside the sphere 100. The provision of the connecting hole 600 facilitates air flow between the first through hole 200 and the fourth through hole 500, thereby increasing the heat exchange rate of the thermal storage ball and reducing the wind resistance of the thermal storage ball.

[0045] Specifically, the diameter of the communicating hole 600 is the same as the diameter of the first through hole 200 .

[0046] After a certain number of through holes are added to the spherical body 100 of the heat storage ball, since multiple heat storage balls need to be stacked on each other during use, the openings of the first through hole 200, the second through hole 300, or the third through hole 400 of some heat storage balls may be completely blocked by the spherical surface of other adjacent heat storage balls, resulting in a significant reduction in the heat exchange rate of the heat storage balls and an increase in the wind resistance of the heat storage balls. Therefore, the following improvements are made to the heat storage balls:

[0047] In an embodiment, a first air guide groove 700 is provided on the periphery of the orifice of the first through hole 200, and the first air guide groove 700 extends radially along the axis of the first through hole 200; a second air guide groove 800 is provided on the periphery of the orifice of the second through hole 300, and the second air guide groove 800 extends radially along the axis of the second through hole 300; a third air guide groove 900 is provided on the periphery of the orifice of the third through hole 400, and the third air guide groove 900 extends radially along the axis of the third through hole 400. A first air guide groove 700 is set. When the adjacent heat storage ball just blocks the opening of the first through hole 200, the air flow can still flow through the first air guide groove 700 through the opening, thereby avoiding the complete failure of the opening; similarly, a second air guide groove 800 is set. When the adjacent heat storage ball just blocks the opening of the second through hole 300, the air flow can still flow through the second air guide groove 800 through the opening, thereby avoiding the complete failure of the opening; similarly, a third air guide groove 900 is set. When the adjacent heat storage ball just blocks the opening of the third through hole 400, the air flow can still flow through the third air guide groove 900 through the opening, thereby avoiding the complete failure of the opening.

[0048] In the embodiment, four first air guide grooves 700 are provided and are evenly arranged around the axis of the first through hole 200; four second air guide grooves 800 are provided and are evenly arranged around the axis of the second through hole 300; and four third air guide grooves 900 are provided and are evenly arranged around the axis of the third through hole 400. The four first air guide grooves 700 are provided in a surrounding manner, which is conducive to improving the directional air circulation effect of the first air guide grooves 700 and maintaining the heat storage ball with good structural strength near the periphery of the opening of the first through hole 200; the four second air guide grooves 800 are provided in a surrounding manner, which is conducive to improving the directional air circulation effect of the second air guide grooves 800 and maintaining the heat storage ball with good structural strength near the periphery of the opening of the second through hole 300; and the four third air guide grooves 900 are provided in a surrounding manner, which is conducive to improving the directional air circulation effect of the third air guide grooves 900 and maintaining the heat storage ball with good structural strength near the periphery of the opening of the third through hole 400.

[0049] It is conceivable that the number of first air guide grooves 700 set on the periphery of the orifice of each first through hole 200 can also be other numbers, for example, one, two, three or more, and those skilled in the art can specifically configure it according to actual needs; the number of second air guide grooves 800 set on the periphery of the orifice of each second through hole 300 can also be other numbers, for example, one, two, three or more, and those skilled in the art can specifically configure it according to actual needs; the number of third air guide grooves 900 set on the periphery of the orifice of each third through hole 400 can also be other numbers, for example, one, two, three or more, and those skilled in the art can specifically configure it according to actual needs.

[0050] In the embodiment, the first air guide groove 700, the second air guide groove 800, and the third air guide groove 900 are all arc-shaped grooves, which are relatively easy to manufacture and have good performance. It is conceivable that the first air guide groove 700, the second air guide groove 800, and the third air guide groove 900 can also be, for example, trapezoidal grooves, square grooves, etc., and those skilled in the art can configure them according to actual needs.

[0051] In the embodiment, the sphere 100 is made of alumina, so that the heat storage ball has higher structural strength and density and better heat storage capacity.
