Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and in particular to a sampling spoon for a large-tonnage smelting furnace. Background Technology

[0002] In the metal smelting process, it is necessary to test and analyze the chemical composition of the melt in the smelting furnace. If the composition meets the standard requirements, or if it does not, the composition of the melt in the smelting furnace is adjusted appropriately based on the analysis results. For example, in aluminum alloy smelting and semi-continuous production, a sample of the aluminum alloy melt is usually taken using a container. After the melt is removed, it is cast into a specific mold and solidified into an ingot. Subsequently, the aluminum alloy ingot is machined and then its chemical composition is analyzed using a direct-reading spectrometer.

[0003] Conventional aluminum alloy sampling spoons are made of stainless steel. However, with the upgrading of equipment in aluminum processing and production enterprises, the size of aluminum alloy melting furnaces is getting larger and larger. The length of the sampling spoon has also increased from the original 1-2 meters to 4-5 meters. If stainless steel is used to make the sampling spoon, its weight will reach 18-20 kg, making manual operation extremely difficult, or even impossible to implement sampling technology.

[0004] In addition, the existing sampling spoons for smelting furnaces have a fixed overall length, which presents a technical problem as they are not well-suited to the space of the production environment or the size of the smelting furnace. Summary of the Invention

[0005] The main objective of this invention is to provide a sampling spoon for a large-tonnage smelting furnace to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes a sampling spoon for a large-tonnage smelting furnace, comprising a spoon head, a head handle, a connecting rod, a tail handle, and a fixing member. The connecting rod has a receiving cavity that extends through the connecting rod along its axis. The two ends of the head handle are respectively connected to the spoon head and the connecting rod. The tail handle is slidably received within the receiving cavity and has a plurality of first connecting holes arranged along the axial direction of the tail handle and extending through the tail handle radially. One end of the connecting rod opposite the head handle has a through hole that extends through the connecting rod radially. The fixing member is received within the through hole and connected to one of the first connecting holes.

[0007] In an alternative embodiment, the spacing between adjacent first connection holes is 5 cm.

[0008] In an optional embodiment, the tailstock has a weight-reducing cavity that extends through the tailstock along its axial direction.

[0009] In an optional embodiment, the handle is provided with an external thread on the outer side of one end of the spoon head, and the receiving cavity is provided with an internal thread on one end of the tail handle, the internal thread engaging with the external thread.

[0010] Compared with the prior art, the present invention has the following technical effects: 1. This utility model provides a sampling spoon for a large-tonnage smelting furnace. A receiving cavity is opened in the connecting rod, and multiple first connecting holes are opened in the tail handle. This significantly reduces the weight of the sampling spoon and lowers the difficulty of operation for workers. Furthermore, by adjusting the relative position of the tail handle and the connecting rod, the overall length of the sampling spoon can be adjusted, improving its applicability to various production environments and smelting furnace sizes.

[0011] 2. By creating a weight-reducing cavity in the tail handle, using titanium alloy (which has a lower density than stainless steel) for the spoon head and handle, and using aluminum alloy (which has a lower density than stainless steel) for the tail handle, the weight of the sampling spoon is further reduced.

[0012] This utility model proposes another sampling spoon for a large-tonnage smelting furnace, including a spoon head, a head handle, a connecting rod, a tail handle, a fixing member, and a heat dissipation device. The connecting rod has a receiving cavity that extends through the connecting rod along its axis. The two ends of the head handle are respectively connected to the spoon head and the connecting rod. The tail handle is slidably received in the receiving cavity. The connecting rod has a second connecting hole at one end opposite to the head handle that extends through the connecting rod in the radial direction. The fixing member is connected to the second connecting hole and abuts against the tail handle. The tail handle has a weight-reducing cavity that extends through the tail handle in the axial direction. The heat dissipation device includes a base plate, a drive unit, fan blades, and a power supply unit. The base plate is installed at one end of the tail handle opposite to the spoon head. The drive unit is installed on the base plate. The fan blades are installed on the output shaft of the drive unit and housed in the weight reduction cavity. The power supply unit is installed on the base plate and is electrically connected to the drive unit.

[0013] In an alternative embodiment, the heat dissipation device further includes a protective housing mounted on the base plate, and the power supply component is housed within the protective housing.

[0014] In an optional embodiment, the heat dissipation device further includes a control button, and the driving component and the power supply component are electrically connected to the control button.

[0015] In an optional embodiment, the connecting rod is provided with a heat dissipation hole, which penetrates the connecting rod radially and communicates with the receiving cavity.

[0016] In an alternative embodiment, the base plate is made of a heat-insulating material.

[0017] In an optional embodiment, the handle is provided with an external thread on the outer side of one end of the spoon head, and the receiving cavity is provided with an internal thread on one end of the tail handle, the internal thread engaging with the external thread.

[0018] Compared with the prior art, the present invention has the following technical effects: 1. This utility model provides a sampling spoon for a large-tonnage smelting furnace. It features a receiving cavity in the connecting rod, a weight-reducing cavity in the tail shank, and multiple first connecting holes in the tail shank. This significantly reduces the weight of the sampling spoon and lowers the difficulty of operation for workers. Furthermore, by adjusting the relative position of the tail shank and the connecting rod, the overall length of the sampling spoon can be adjusted, improving its applicability to various production environments and smelting furnace sizes.

[0019] By setting a heat dissipation device that connects to the weight reduction chamber at one end of the tailstock, the heat dissipation device generates cooling air to dissipate heat from the connecting rod and tailstock, thereby reducing the temperature of the connecting rod and tailstock and preventing them from overheating and becoming unusable.

[0020] 2. By using titanium alloy, which has a lower density than stainless steel, for the spoon head and handle, and aluminum alloy, which has a lower density than stainless steel, the weight of the sampling spoon is further reduced. Attached Figure Description

Example 1

[0027] Please refer to Figures 1-4 This utility model proposes a sampling spoon 100 for a large-tonnage smelting furnace.

[0028] Please refer to Figure 3 and Figure 4In this embodiment of the present invention, a sampling spoon 100 for a large-tonnage smelting furnace includes a spoon head 1, a handle 2, a connecting rod 3, a tail handle 4, and a fixing member 5. The connecting rod 3 has a receiving cavity 31, which extends through both ends of the connecting rod 3 along its axis. The two ends of the handle 2 are respectively connected to the spoon head 1 and the connecting rod 3. The tail handle 4 is slidably received in the receiving cavity 31 and has several first connecting holes 41. The several first connecting holes 41 are arranged along the axial direction of the tail handle 4 and extend through both ends of the tail handle 4 in the radial direction. A through hole 32 is provided at one end of the connecting rod 3 opposite to the handle 2. The through hole 32 extends through the connecting rod 3 in the radial direction, and the fixing member 5 is received in the through hole 32 and connected to a first connecting hole 41.

[0029] Please refer to Figure 2 and Figure 4 The handle 2 has an external thread 21 on its outer side relative to the spoon head 1, and the receiving cavity 31 has an internal thread 33 on its outer side relative to the tail handle 4. The internal thread 33 engages with the external thread 21. The handle 2 is fixedly connected to the spoon head 1 by welding or integral molding. The fixing member 5 is one of bolts, screws, or threaded rods. The first connecting hole 41 is a threaded hole, and the fixing member 5 engages with the first connecting hole 41.

[0030] Specifically, the inclusion cavity 31 in the connecting rod 3 significantly reduces the weight of the sampling spoon 100, simplifying operation for workers. The tail handle 4 can slide within the inclusion cavity 31 and is secured by the fixing member 5 and the first connecting hole 41 on the tail handle 4 to prevent slippage of the tail handle 4 during use. By adjusting the relative position of the tail handle 4 and the connecting rod 3, the overall length of the sampling spoon 100 can be adjusted, allowing it to adapt to different working environments or melting furnaces of different sizes, thus improving its applicability. To reduce the impact of the high temperature of the melting furnace on the fixing member 5, ceramic bolts can be used.

[0031] Furthermore, by opening several first connecting holes 41 in the tail handle 4, the weight of the sampling spoon 100 can be further reduced. Additionally, a weight-reducing cavity 42 can be provided in the tail handle 4, extending through the tail handle 4 along its axial direction, significantly reducing the weight of the sampling spoon 100.

[0032] Please refer to Figure 1 and Figure 2 In the specific implementation of this utility model, both the spoon head 1 and the handle 2 are made of titanium alloy. Since the spoon head 1 and handle 2 need to be inserted into the melting furnace to scoop up the high-temperature molten material during the sampling process, high-strength, high-temperature resistant, and corrosion-resistant titanium alloy is used to make the spoon head 1 and handle 2. The alloy melted in the melting furnace is aluminum alloy, and the titanium alloy used to make the spoon head 1 and handle 2 is one of TA19 titanium alloy, TA15 titanium alloy, or Ti53311S titanium alloy, but is not limited to these.

[0033] In addition, since the handle 2 needs to be inserted into the melting furnace to scoop up the high-temperature molten alloy, in order to ensure the stability of the handle 2, the method of opening a cavity cannot be used to reduce weight. Therefore, titanium alloy, which has a lower density than stainless steel, is used to replace stainless steel to make the spoon head 1 and handle 2, which can further reduce the weight of the sampling spoon 100.

[0034] The connecting rod 3 is made of stainless steel. In the overall structure of the sampling spoon 100, the length of the connecting rod 3 is greater than the length of the head handle 2 and the tail handle 4, accounting for most of the overall length of the sampling spoon 100. It is also located in the stress-bearing part. Therefore, the connecting rod 3 is made of stainless steel, which has high strength and high rigidity and is more economical than titanium alloy and aluminum alloy, so as to meet both the use requirements and the economic requirements.

[0035] The tail handle 4 is made of aluminum alloy, such as one of the grades EA43400, ADC12, ZL102, A360, 516, or 560, but not limited to these. Aluminum alloy has a lower density than stainless steel, its strength and rigidity meet the usage requirements, and it is more economical than titanium alloy. Using aluminum alloy to make the tail handle 4 can further reduce the weight of the sampling spoon 100.

[0036] Please refer to Figure 1 and Figure 2 The length of the sampling spoon 100 is 4 to 5 meters, and the length of the head handle 2 is 80 cm to 120 cm. The appropriate length of the head handle 2 is selected according to the working environment, the size of the smelting furnace and the usage requirements, such as 90 cm, 100 cm or 110 cm. In this embodiment, the length of the head handle 2 is 100 cm.

[0037] In the overall structure of the sampling spoon 100, the connecting rod 3 serves as a support point for the worker's hand grip, is located in the stress-bearing part, and has a receiving cavity 31 to reduce weight. The length of the connecting rod 3 is greater than the length of the head handle 2 and the tail handle 4, and accounts for a relatively large proportion of the overall length of the sampling spoon 100. The length of the connecting rod 3 is 180cm~220cm, and a suitable length of the connecting rod 3 is selected according to the working environment, the size of the smelting furnace, and the usage requirements, such as 190cm, 200cm, or 210cm. In this embodiment, the length of the connecting rod 3 is 200cm.

[0038] The length of the tail handle 4 is 80cm to 120cm. The appropriate length of the tail handle 4 is selected according to the working environment, the size of the smelting furnace, and the usage requirements, such as 90cm, 100cm, or 110cm. In this embodiment, the length of the tail handle 4 is 100cm. The number of first connecting holes 41 opened in the tail handle 4 is 18, and the distance between adjacent first connecting holes 41 is 5cm, providing more options for adjusting the length of the sampling spoon 100.

[0039] The diameter of the spoon head 1 is 40cm to 60cm. The appropriate diameter of the spoon head 1 is selected according to the working environment, the size of the smelting furnace and the usage requirements, such as 45cm, 50cm and 55cm. In this embodiment, the diameter of the spoon head 1 is 45cm.

[0040] In a specific application of this utility model, the tail shank 4 is housed in the receiving cavity 31. The appropriate length of the sampling spoon 100 is selected according to the working environment, the size of the smelting furnace and the usage requirements. The corresponding first connecting hole 41 is aligned with the through hole 32. The fixing member 5 passes through the through hole 32 and engages with the first connecting hole 41 to fix the tail shank 4 in the connecting rod 3. Example 2

[0041] Please refer to Figures 5-7 This utility model also provides another embodiment of the sampling spoon 100 for a large-tonnage smelting furnace: Please refer to Figures 4-7 Compared to Example 1, in Example 2, the sampling spoon 100 for the large-tonnage smelting furnace no longer has several first connecting holes 41. The through hole 32 in Example 1 is improved to a second connecting hole 34; specifically, the through hole 32 in Example 1 is tapped to become a threaded hole. The fixing member 5 engages with the second connecting hole 34 and abuts against the tail handle 4, securing the tail handle 4 within the receiving cavity 31.

[0042] Secondly, please refer to Figures 6-7 In Example 2, the sampling spoon 100 for the large-tonnage smelting furnace is also equipped with a heat dissipation device 6. The heat dissipation device 6 includes a base plate 61, a drive component 62, a fan blade 63, and a power supply component 64. The base plate 61 is installed on the end of the tail handle 4 opposite to the spoon head 1 by screw connection. The drive component 62 is installed on the base plate 61 by screw connection. The fan blade 63 is installed on the output shaft of the drive component 62 by screw connection and is housed in the weight reduction cavity 42. The power supply component 64 is installed on the base plate 61 and is electrically connected to the drive component 62. The drive component 62 is a motor with a rotatable output shaft, and the output shaft of the drive component 62 is parallel to, and preferably coincides with, the axis of the tail handle 4.

[0043] Specifically, please refer to Figures 6-7 In embodiment 2, the heat dissipation device 6 further includes a protective shell 65, which is mounted on the base plate 61 by screws. The power supply component 64 is housed within the protective shell 65. Further, the power supply component 64 is a battery, which is fixed within the protective shell 65 by a slot or clip, and then mounted on the base plate 61 via the protective shell 65. The base plate 61 is made of a heat-insulating material, such as fiberglass, asbestos, or rock wool, but not limited to these, to prevent heat from the sampling spoon 100 from being transferred to the power supply component 64, thus affecting its performance.

[0044] The heat dissipation device 6 also includes a control button 66, and the drive unit 62 and the power supply unit 64 are electrically connected to the control button 66. The control button 66 is mounted on the outside of the protective housing 65 and is used to control the on / off state of the circuit from the power supply unit 64 to the drive unit 62.

[0045] In addition, in embodiment 2, the connecting rod 3 is provided with a heat dissipation hole 35, which penetrates the connecting rod 3 in the radial direction and connects to the receiving cavity 31.

[0046] In a specific application of this utility model, the working environment of the sampling spoon 100 causes the temperature of the connecting rod 3 and the tail handle 4 to gradually rise, which is not conducive to worker operation. By pressing the control button 66 to control the on / off of the circuit from the power supply component 64 to the drive component 62, the drive component 62 drives the fan blade 63 to rotate and generate cooling air. The cooling air is discharged through the end of the tail handle 4 where the base plate 61 is installed, the end of the connecting rod 3 connected to the head handle 1, and the heat dissipation hole 35, thereby reducing the temperature of the connecting rod 3 and the tail handle 4 and preventing the connecting rod 3 and the tail handle 4 from becoming too hot and unable to be used normally.

[0047] Apart from the different technical means mentioned above, the other technical means in Embodiment 2 are the same as those in Embodiment 1, and will not be described in detail here.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
