[0025] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The utility model provides a high-permeability heating riser. By combining accessories, a high-permeability exhaust sheet is added to the top of the heating riser. The air permeability of the high-permeability heating riser is improved, which is convenient for exhausting the gas inside the riser, can meet the demand for rapid filling of the riser, and is conducive to filling of body fluids. The exhaust component has a built-in ring and corresponding combination buckles and combination grooves. The built-in ring is convenient for improving the strength of the exhaust component without affecting the ventilation effect. The combination buckles and combination grooves can improve the combination effect. Please refer to Figure 1 to Figure 4 , including a cylinder component 100, and an exhaust component 200 disposed on the top of the cylinder component 100;

[0027] The cylinder assembly 100 includes a cylinder shell 110, and a combination buckle 120 is oppositely arranged on the top of the cylinder shell 110. The number of the combination buckles 120 can be adjusted according to actual needs. The top of the cylinder assembly 100 is integrally formed with a through hole 130 reserved, and the through hole 130 is cylindrical from top to bottom;

[0028] The exhaust assembly 200 includes a bottom sheet 210 disposed at the bottom and in contact with the top of the cylindrical shell 110, an inner ring 220 disposed at the top of the bottom sheet 210, and a top sheet 270 disposed at the top of the inner ring 220. The bottom sheet 210 and the top sheet 270 are both made of ceramsite sand with a diameter of 2-3 mm. The gaps between the ceramsite sands are relatively large, which facilitates the exhaust of gas inside the riser and facilitates the filling of body fluids.

[0029] During specific use, firstly, a combination buckle 120 is arranged on the cylindrical shell 110, a through hole 130 is arranged inside the cylindrical shell 110, and at the same time, an exhaust assembly 200 is arranged on the top of the cylindrical shell 110, and the exhaust assembly 200 is composed of a bottom sheet 210 carrying a combination groove 211, an internal ring 220 and a top sheet 270. The bottom sheet 210 and the top sheet 270 are made of expanded clay sand for easy ventilation. The internal ring 220 is an annular structure carrying tendons 1 230 and tendons 2 240, which has gaps and will not affect ventilation. Moreover, the internal ring 220 is also made of expanded clay sand. The air permeability of conventional heating risers needs to be improved, and cannot meet the requirements of rapid filling of molten iron. The heating riser of this scheme, that is, a highly permeable exhaust assembly 200 is added to the top of the heating riser. The air permeability of this highly permeable heating riser is significantly improved, which can meet the requirements of rapid filling of the riser.

[0030] At the same time, in order to facilitate the combination of the two, specifically, the bottom of the bottom film 210 is provided with oppositely arranged combination grooves 211, and the setting position and size of the combination grooves 211 match the setting position and size of the combination buckle 120.

[0031] Subsequently, in order to increase the strength while achieving ventilation, so that the strength and ventilation do not affect each other, specifically, the inner wall of the circumference of the built-in ring 220 is provided with an integrally formed rib 1 230 and a rib 2 240, the ends of the rib 1 230 and the rib 2 240 are connected with a gasket 250, and the top of the gasket 250 is integrally connected with a combination cap 260;

[0032] In some embodiments, in order to avoid the influence of the built-in ring 220 on breathability, the number of ribs 1 230 and ribs 2 240 can be reduced to maximize breathability while still ensuring strength. This part can be adjusted according to actual conditions, and the built-in ring 220 can be made of the same material as the bottom sheet 210 and the top sheet 270.

[0033] Next, in order to facilitate assembly and splicing, specifically, an assembly hole matching the assembly cap 260 is provided at the bottom of the top plate 270 .

[0034] Furthermore, for ease of use, specifically, a heating element 280 is provided at the bottom of the bottom film 210. The heating element 280 may also be in a rod shape and fixed on the top of the inside. The heating element 280 is fixed by a secondary molding method. The heating element 280 may be made of a thermal material containing an aluminum thermal component.

[0035] Finally, in order to ensure that the breathability effect is improved, specifically, the material of the inner ring 220, the bottom sheet 210 and the top sheet 270 is ceramsite sand.

[0036] In addition, the conventional accessories and conventional structures involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to internal structures and methods.
