It is named for the volute shape of the key flow channel that guides the flue gas or heat source. It is mainly used in boiler heating and metal melting. In the field of metal melting, its single-channel design focuses on non-ferrous metal smelting, reduces metal loss, ensures metallurgical quality, and allows for flexible production switching, making it suitable for small-batch production of multiple alloy grades.

[0003] Currently, in the process of processing metal in a single-channel volute furnace, the metal needs to be added into the heat exchange component, such as the crucible, and then the crucible is placed on the heat exchange support frame inside the volute furnace. In the operation of traditional volute furnaces, the placement of the crucible relies on manual visual inspection and experience. Operators need to place the crucible in the placement area of ​​the heat exchange support frame based on subjective judgment, which is prone to tilting. This tilting can easily cause the molten material inside to spill due to the crucible's imbalance, resulting in waste of raw materials and potential damage to the heat exchange support frame components below, which is detrimental to the use of the support frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a new technical solution: The volute furnace body 1 serves as the main frame of the device, providing a closed space for smelting operations, supporting the heat exchange and crucible placement structure, and ensuring the effective retention of high-temperature flue gas and heat. The flue gas inlet pipe 2 is fixedly installed on the front end of the outer surface of the volute furnace body 1 and extends into the interior of the furnace body 1; its function is to introduce the high-temperature flue gas from the outside into the interior of the furnace body 1 to provide a heat source for heating the crucible 10 and to serve as the heat input channel for the heat exchange process. The furnace cover 3 is rotatably installed on the upper end of the volute furnace body 1 and is indirectly connected to the connecting plate 4 through the round rod 15; its function is to seal the opening at the upper end of the furnace body 1 to reduce heat loss, while facilitating the loading and unloading of the crucible 10 and the observation of internal operations. The connecting plate 4 is fixedly connected to the upper end of the rear surface of the volute furnace body 1; its function is to serve as the mounting carrier for the furnace cover 3, and to provide support for the round rod 15 through the connecting mounting plate 14, thereby enabling the furnace cover 3 to rotate. The guide plate 5 is fixedly connected to the upper surface of the placement plate 8 in a ring array, with a limiting groove 9 on the inner side and the upper surface connected to the ring plate 13; its function is to provide guidance for the placement of the crucible 10, guide the limiting plate 6 to slide precisely into the limiting groove 9, and at the same time provide lateral support for the crucible 10. The limiting plates 6 are fixedly connected to the outer surface of the crucible 10 in a ring array; their function is to slide into the limiting groove 9 of the guide plate 5 to limit the radial displacement of the crucible 10 and prevent it from shifting due to vibration during the melting process. The support plates 7 are fixedly connected to the inner wall of the volute furnace body 1 in a ring array, and the near ends are connected to the placement plate 8; their function is to connect the furnace body 1 and the placement plate 8, provide stable support for the placement plate 8 and the crucible 10 and other components above it, and distribute the load-bearing pressure. The placement plate 8 is fixedly connected to the near ends of the three support plates 7. The upper surface is equipped with a guide plate 5, and the lower inner wall is equipped with a positioning rod 11. Its function is to serve as a direct placement platform for the crucible 10, integrating the guiding, limiting and positioning structures to ensure the stability of the crucible 10. The limiting groove 9 is formed on the inner side of the three guide plates 5; its function is to provide sliding and insertion space for the limiting plate 6, and to achieve precise positioning and radial fixation of the crucible 10 through the cooperation of the groove and the plate. The crucible 10 is placed inside the placement plate 8, with a limiting plate 6 on the outer surface and a positioning groove 12 on the lower surface; its function is to hold the material to be melted and melt the material by absorbing the heat in the furnace body 1. It is the core container for the smelting operation. The positioning rod 11 is fixedly connected to the lower inner wall of the placement plate 8 and can be inserted into the positioning groove 12 of the crucible 10. Its function is to achieve axial positioning of the crucible 10. Together with the limiting plate 6 and the limiting groove 9, it ensures that the center of the crucible 10 is aligned when it is placed and avoids tilting. The positioning groove 12 is formed on the lower surface of the crucible 10; its function is to be adapted to the positioning rod 11 and to provide a bottom positioning reference for the crucible 10 through the plug-in structure, thereby improving the placement accuracy. The annular plate 13 is fixedly connected to the upper surface of the three guide plates 5; its function is to form an annular protective structure to prevent external debris from falling into the limiting groove 9, and at the same time enhance the overall structural strength of the three guide plates 5. Mounting plates 14 are fixedly connected to the left and right surfaces of the connecting plate 4, with their adjacent ends connected to the round rod 15; their function is to connect the connecting plate 4 and the round rod 15, provide support points for the round rod 15, and ensure the stability of the furnace cover 3 when it rotates. The round rod 15 is fixedly connected to the near ends of the two mounting plates 14, and the furnace cover 3 is rotatably mounted on its outer surface; its function is to serve as the rotation axis of the furnace cover 3, so that the furnace cover 3 can rotate around it to open and close, reducing the difficulty of operation. The handle 16 is fixedly connected to the front surface of the furnace cover 3; its function is to provide the operator with a gripping point, making it easier to exert force to rotate the furnace cover 3 and improving the convenience of opening and closing operations. The flue gas duct 17 is fixedly installed on the lower surface of the volute furnace body 1, and its upper end extends into the interior of the furnace body 1; its function is to discharge the low-temperature flue gas after heat exchange in the furnace body 1, complete the circulation of flue gas, and ensure the stability of the gas pressure inside the furnace.

[0018] Furthermore, the furnace lid 3 is opened by rotating the round rod 15. The crucible 10 is not placed inside the furnace body 1, and the positioning rod 11 on the placement plate 8 is exposed. The limiting grooves 9 of the three guide plates 5 are arranged in a ring. Using a tool, the crucible 10 is aligned with the top of the placement plate 8. The three limiting plates 6 on the outer surface of the crucible are inserted into the corresponding limiting grooves 9 and slide down along the inner wall of the guide plate 5. At the same time, the positioning groove 12 on the lower surface of the crucible is aligned and fitted into the cylindrical positioning rod 11 until the limiting plate 6 is completely slid into the limiting groove 9. The crucible is stably placed on the placement plate 8. The furnace lid 3 is closed, and the high-temperature flue gas enters the furnace body 1 through the flue gas inlet pipe 2. After heat exchange along the single-channel volute path, it is discharged from the flue gas exhaust pipe 17. The heat is passed through the crucible to heat the internal material. After the operation is completed, the furnace lid 3 is opened, and the crucible is lifted upward. The limiting plate 6 slides out along the limiting groove 9, and the positioning groove 12 separates from the positioning rod 11, so the crucible can be taken out.

[0019] By inserting the positioning rod 11 into the positioning groove 12, and with the sliding fit between the limiting plate 6 and the limiting groove 9, the crucible can be quickly centered and positioned, avoiding placement deviation, reducing the difficulty of alignment when placing the crucible, eliminating the need for repeated position adjustments, and improving loading and unloading efficiency. The ring-shaped guide plate and limiting plate form a three-point support to prevent the crucible from shifting due to vibration during melting, thereby improving the performance of the heat exchange support frame.

[0020] Example 1 (for reference) Figure 4 ) When the positioning rod 11 is a cylindrical rod, the contact area between the cylindrical rod and the inner wall of the positioning groove is uniform, which can withstand the radial pressure when the crucible is fully loaded, and avoid the positioning groove from deforming due to excessive local stress after long-term use; Example 2 (for reference) Figure 5 ) When the positioning rod 11 is set with a rounded top, the rounded top design reduces the dependence on the operator's skill level, makes it easier to place the crucible, and the rounded transition can also prevent sharp edges from scratching the inner wall of the positioning groove, extending the service life of the crucible. It is especially suitable for non-standardized production scenarios with small batches and high frequency.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
