[0022] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present invention provides a furnace wall structure for a furnace outlet, such as Figure 1-6 As shown, the furnace wall structure at the furnace outlet includes: a combined furnace wall body 1 arranged on multiple furnace bottom plates 2, the furnace bottom plates 2 are fixedly connected by first bolts 4, the combined furnace wall body 1 is composed of multiple cast iron frames 5, and multiple criss-cross horizontal ribs 6 and longitudinal ribs 7 are fixed in the cast iron frames 5 to increase the strength; multiple second bolts 8, multiple second bolts 8 are arranged on the cast iron frames 5, and are used to connect and fix adjacent cast iron frames 5; a detachable furnace frame 9, the furnace frame 9 is arranged on the cast iron frame 5, and the furnace frame 9 is adapted to the furnace outlet of the calcium carbide furnace.

[0024] In this embodiment, the modular furnace wall body 1 is supported by multiple furnace bottom plates 2 and secured together with first bolts 4. This design makes the furnace wall structure more stable, capable of withstanding high-temperature pressure. It also improves the overall stability and durability of the furnace wall structure and reduces safety hazards caused by thermal deformation. The cast iron frame 5, the basic unit of the furnace wall structure, is internally fixed with multiple crisscrossing horizontal and vertical ribs 6 and 7. These ribs not only increase the strength of the cast iron frame 5 but also serve to dissipate heat. The design of the reinforced ribs addresses the fragility of the cast iron plate while reducing the overall weight. Furthermore, the ribs act as heat sinks, helping to reduce the temperature of the furnace wall. Multiple second bolts 8 are provided on the cast iron frame 5 to connect and secure adjacent cast iron frames 5. This connection method makes the furnace wall structure more flexible, allowing the size and shape of the furnace wall to be adjusted as needed. It enhances the modularity and flexibility of the furnace wall structure and facilitates installation and disassembly. Furthermore, the bolted connection increases the stability of the furnace wall structure. The furnace frame 9 is mounted on the cast iron frame 5 and is compatible with the furnace mouth of the calcium carbide furnace. This design allows the furnace frame 9 to be replaced or repaired as needed; it improves the maintainability of the furnace wall structure and reduces the risk of production interruption due to damage to the furnace frame.

At the same time, this structure also has the advantages of good stability, strong combinability, high flexibility, and good maintainability, and is suitable for the furnace wall structure of the furnace outlet of various calcium carbide furnaces.

These groove blocks match the shape of the longitudinal ribs 7, and the furnace frame 9 can also be further fixed to the cast iron frame 5 by snapping; the snapping of the second groove blocks 14 and the longitudinal ribs 7 not only enhances the stability of the furnace frame 9 in the longitudinal direction, but also makes the entire furnace wall structure more firm and reliable in the vertical direction. This design helps to prevent the furnace frame 9 from deforming or loosening due to thermal expansion and contraction in a high temperature environment; through the clamping design of the first groove block 13 and the transverse rib plate 6, and the second groove block 14 and the longitudinal rib plate 7, the installation and disassembly process of the entire furnace wall structure becomes simpler and more convenient. In summary, by introducing the design of the first groove block 13 and the second groove block 14, the furnace outlet furnace wall structure of the utility model further improves the installation stability of the furnace frame 9 and the reliability of the entire furnace wall structure while maintaining the original advantages.

[0028] In this embodiment, a threaded barrel 11 is fixed to the top of the furnace frame 9, and a matching screw 12 is provided on the cast iron frame 5. During installation, the bottom end of the screw 12 will thread into the threaded barrel 11, thereby achieving a tight connection between the furnace frame 9 and the cast iron frame 5. This threaded connection not only provides additional fixing force, ensuring the vertical stability of the furnace frame 9, but also makes the connection between the furnace frame 9 and the cast iron frame 5 more secure and reliable.

[0029] In a further preferred embodiment of the present invention, a third bolt 15 is provided on the second groove block 14 , and the third bolt 15 is threadedly passed through the corresponding longitudinal rib plate 7 .

[0030] In this embodiment, a third bolt 15 is provided on the second groove block 14 , and the third bolt 15 passes through the corresponding longitudinal rib 7 , thereby more firmly fixing the second groove block 14 (i.e., the bottom portion of the furnace frame 9 ) to the cast iron frame 5 .
