Description

Technical Field

[0001] This utility model relates to the field of alloy smelting technology, and in particular to a drying device for alloy smelting. Background Technology

[0002] Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, and small amounts of carbon and other elements. It is a widely used and produced ferroalloy. Silicon-manganese alloy is a commonly used composite deoxidizer in steelmaking and a reducing agent in the production of low-carbon ferromanganese and the electro-silicon thermal process for producing metallic manganese. Currently, the main method for producing silicon-manganese alloy in my country is through smelting technology, which involves extracting the alloy from ores using methods such as roasting, smelting, electrolysis, and the use of chemical reagents.

[0003] In the smelting process of ferrosilicon alloys, drying equipment is often required to treat the raw materials to remove moisture or other volatile substances. During the drying process, the raw materials tend to pile up naturally, resulting in poor drying of the inner layers and a longer drying time. Utility Model Content

Multiple heat dissipation fin groups correspond one-to-one with the multiple branch pipes. Each heat dissipation fin group includes multiple heat dissipation fins. The multiple heat dissipation fins are spaced apart on the branch pipes along the extension direction of the branch pipes.

[0037] Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, and small amounts of carbon and other elements. It is a widely used and produced ferroalloy. Silicon-manganese alloy is a commonly used composite deoxidizer in steelmaking and a reducing agent in the production of low-carbon ferromanganese and the electro-silicon thermal process for producing metallic manganese. Currently, the main method for producing silicon-manganese alloy in my country is through smelting technology, which involves extracting the alloy from ores using methods such as roasting, smelting, electrolysis, and the use of chemical reagents.

[0038] In the smelting process of ferrosilicon alloys, drying equipment is often required to treat the raw materials to remove moisture or other volatile substances. During the drying process, the raw materials tend to pile up naturally, resulting in poor drying of the inner layers and a longer drying time.

[0039] This utility model proposes a drying device for alloy smelting.

[0040] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the drying device for alloy smelting includes a base 1, a drying tank 2, a cover plate 3, a hot air supply assembly 4, at least two partition plates 5, and a drive assembly 6. The drying tank 2 extends along a first horizontal direction and is rotatably mounted on the base 1 about an axis extending along the first horizontal direction. The peripheral wall of the drying tank 2 is provided with a feeding port 21. The drying tank 2 has a first end face 23 and a second end face 24 oppositely arranged in the first horizontal direction. The first end face 23 is provided with an air inlet 25, and the second end face 24 is provided with an air outlet. The cover plate 3 is used to cover the feeding port 21. The hot air supply assembly 4 is connected to the air inlet 25 and is used to supply hot air to the air inlet 25. At least two partition plates 5 are located inside the drying tank 2, and at least two partition plates 5 extend along the first horizontal axis, and at least two partition plates 5 are spaced apart about the axis extending along the first horizontal direction on the peripheral wall of the drying tank 2. The drive assembly 6 is used to drive the drying tank 2 to rotate.

[0041] In this invention, the driving component 6 drives the drying tank 2 to rotate. After the drying tank 2 rotates a certain angle, the alloy raw material on the upper side of the partition plate 5 falls, tumbling the alloy raw material and exposing the internal alloy raw material. The heating air component 4 supplies hot air into the drying tank 2 to accelerate the drying of the alloy raw material. As the alloy raw material falls from the partition plate 5, the gaps between the alloy raw materials increase, allowing the hot air to contact the alloy raw material more fully, thus improving the drying efficiency. Overall, this accelerates the drying efficiency of the alloy raw material and shortens the drying time.

[0042] The drying tank 2 can be round or square, and is not limited here; specifically, the drying tank 2 is round, and the axis of the drying tank 2 extends along a first horizontal direction. The drying tank 2 is rotatably mounted on the upper side of the base 1 along its axis. The cover plate 3 can be detachably connected or movably connected to the drying tank 2, and is not limited here; specifically, the cover plate 3 is hinged to the drying tank 2, and the hinge axis extends along the first horizontal direction. When the feeding port 21 is rotated and opened, alloy raw materials can be added into the drying tank 2, or raw materials can be removed from the drying tank 2.

[0043] The partition plates 5 can be two, three, or more, and there is no limitation here. Specifically, four partition plates 5 are provided, and the extending plane of each partition plate 5 passes through the axis of the drying tank 2. The included angles between the multiple partition plates 5 are equal. An accommodating cavity 51 is formed between adjacent partition plates 5, and the accommodating cavity 51 can accommodate the alloy raw material. The driving component 6 can be electrically or mechanically driven, and there is no limitation here.

[0044] Please see Figure 1 and Figure 4 The heating air assembly 4 includes a fan 41, a heating box 42, a heating pipe 43, and multiple heat dissipation fin groups 44. The heating box 42 has a first ventilation opening and a second ventilation opening on its opposite side walls. The second ventilation opening is connected to the air inlet of the fan 41, and the air outlet of the fan 41 is connected to the air inlet 25. The multiple heat dissipation fins are all located on the airflow path between the first ventilation opening and the second ventilation opening. The heating pipe 43 is at least partially located inside the heating box 42, and the heating pipe 43 is heat-conductingly connected to the multiple heat dissipation fin groups 44.

[0045] When the fan 41 is started, it can draw air from outside the heating box 42 into the heating box 42 through the first vent. As the air moves toward the second vent, it can come into contact with multiple heat dissipation fin groups 44 to heat the air. Finally, the fan 41 sends the heated air into the drying tank 2 to supply hot air to the drying tank 2.

[0046] A heating medium flows within the heating pipe 43. This heating medium can be hot water or hot air, and is not limited thereto. Specifically, the heating medium within the heating pipe 43 is wastewater or waste gas at a certain temperature, enabling the recycling and reuse of the factory's wastewater and waste gas. The heating pipe 43 can be bent within the heating box 42 to increase the contact area with the heat dissipation fin assembly 44.

[0047] The first vent and the second vent are spaced apart along the second axis. The heating pipe 43 includes a main heating pipe 431 and a plurality of branch pipes 432, all of which are connected to the main heating pipe 431. The plurality of branch pipes 432 are at least partially located inside the heating box 42. The plurality of branch pipes 432 are spaced apart around the second axis. A plurality of heat dissipation fin groups 44 correspond one-to-one with the plurality of branch pipes 432. Each heat dissipation fin group 44 includes a plurality of heat dissipation fins. The plurality of heat dissipation fins are spaced apart on the branch pipes 432 along the extension direction of the branch pipes 432.

[0048] By setting multiple branch pipes 432, the heat dissipation fins are made more densely packed in the heating box 42, increasing the contact area between the heat dissipation fins and the air, thereby enhancing the heating effect on the air and ensuring the temperature of the hot air sent into the drying tank 2.

[0049] The ends of multiple branch pipes 432 extend outside the heating box 42 and are connected to a heat recovery pipe to recover and reuse the heating medium within the branch pipes 432. The number of branch pipes 432 can be two, three, or more, and is not limited here; specifically, the number of branch pipes 432 is set to four. The branch pipes 432 can be bent within the heating box 42 to increase the contact area with the heat dissipation fins.

[0050] From one end of the branch pipe 432 closest to the main heating pipe 431 to the other end, the distance between adjacent heat dissipation fins gradually decreases. From one end of the branch pipe 432 closest to the main heating pipe 431 to the other end, the temperature of the heating medium within the branch pipe 432 gradually decreases, and the temperature of the heat dissipation fins gradually decreases, resulting in a more uniform temperature of the air within the heating pipe.

[0051] Please see Figure 1 A support 11 is mounted on the base 1. The drying tank 2 is coaxially connected to a first rotating shaft. The drive assembly 6 includes a drive motor 61, which is driven by the first rotating shaft. The drive motor 61 enables automatic control of the rotation of the drying tank 2. The drying tank 2 is integrally connected to or welded to the first rotating shaft; this is not limited here. The output shaft of the drive motor 61 can be directly or indirectly connected to the first rotating shaft of the drying tank 2; this is not limited here either.

[0052] Please see Figure 1 The drive assembly 6 further includes a first drive wheel 62, a second drive wheel 63, and a drive belt 64. The first drive wheel 62 is fixedly connected to the output shaft of the drive motor 61, the second drive wheel 63 is fixedly connected to the first rotating shaft, and the drive belt 64 drives the first drive wheel 62 and the second drive wheel 63.

[0053] When the drive motor 61 is started, the drive motor 61 drives the first transmission wheel 62 to rotate, and the first transmission wheel 62 drives the second transmission wheel 63 to rotate through the transmission belt 64, thereby driving the drying tank 2 to rotate.

[0054] The diameter of the second transmission wheel 63 is larger than the diameter of the first transmission wheel 62. Through the first transmission wheel 62, the second transmission wheel 63, and the transmission belt 64, the rotational speed of the drying tank 2 is lower than the rotational speed of the rotor of the drive motor 61, thereby increasing the rotational torque of the drying tank 2 and ensuring the rotational stability of the drying tank 2.

[0055] Please see Figure 1 and Figure 5 A support assembly 7 is provided on the base 1. The support assembly 7 includes a first support wheel 71 and a second support wheel 72. The first support wheel 71 and the second support wheel 72 are rotatably disposed on the base 1 about an axis extending in a first horizontal direction. The first support wheel 71 and the second support wheel 72 are respectively disposed on opposite sides of the drying tank 2. The upper side of the first support wheel 71 and the upper side of the second support wheel 72 abut against the lower side of the drying tank 2.

[0056] By providing the first support roller 71 and the second support roller 72, the drying tank 2 can be supported, improving the stability of the rotating installation of the drying tank 2. When the drying tank 2 rotates, the first support roller 71 and the second support roller 72 can rotate accordingly to ensure the rotation of the drying tank 2.

[0057] Multiple support groups 7 are spaced apart along an axis extending in the first horizontal direction. The cooperation of multiple support groups 7 further improves the stability of supporting the drying tank 2. Two, three, or more support groups 7 can be provided, without limitation; specifically, two support groups 7 are provided.

[0058] Please see Figure 1 , Figure 2 and Figure 3 The drying device for alloy smelting also includes an air guide pipe 22, which extends in the vertical direction. The upper end of the air guide pipe 22 has a third ventilation opening and the lower end has a fourth ventilation opening. The air guide pipe 22 is rotatably disposed at the air inlet 25 around an axis extending in the first horizontal direction, so that the fourth ventilation opening is maintained at the lower end of the air guide pipe 22. The third ventilation opening is connected to the air inlet 25.

[0059] During the rotation of the drying tank 2, the air guide pipe 22 rotates so that the air outlet of the fourth vent can be closer to the alloy raw material inside the drying tank 2, thereby improving the drying effect on the raw material.

[0060] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
