Description

Technical Field

[0001] This application relates to the field of mineral smelting technology, specifically to a sampling device. Background Technology

[0002] Submerged arc furnaces, also known as electric arc furnaces or resistance furnaces, are mainly used for smelting minerals to produce alloy materials such as ferrochrome, ferrosilicon, and ferromanganese. The smelting of silicon ore typically involves using a carbonaceous reducing agent to reduce the elemental silicon in the ore, followed by heating and refining in a submerged arc furnace. After refining, the molten silicon is poured into ingot molds for subsequent crushing.

[0003] To understand the refining process inside the furnace, it is necessary to obtain samples of material at different depths within the furnace for testing using a sampling device. However, traditional sampling devices have a fixed sampling depth and a limited sampling range per operation. To obtain samples at different depths, the sampling device needs to be adjusted multiple times, which affects sampling efficiency and also poses safety hazards. Summary of the Invention

[0004] Therefore, it is necessary to provide a sampling device to address the problem of fixed sampling depth in sampling devices.

[0005] A sampling device, comprising:

[0006] The hanger includes two mounting arms spaced apart in a first horizontal direction;

[0009] A second adjustment assembly is mounted on the first adjustment assembly, and the second adjustment assembly includes a transmission rod movable in a first horizontal direction;

[0010] A sampling rod is installed at one end of a transmission rod. A sampling groove is provided on the outer surface of the sampling rod. The sampling rod can be controlled to rotate around a second horizontal direction that intersects the first horizontal direction, and can switch between a vertically extended first state and a horizontally extended second state.

[0016] In one embodiment, each movable rod has at least two fixing holes, and all fixing holes are spaced apart along a first horizontal direction; the first adjustment assembly further includes:

[0017] Two fixing plates protrude from opposite ends of the first adjusting seat in the first horizontal direction; and

[0018] Two fasteners, one end of each fastener is confined to a fixed plate, and the other end of each fastener is confined to a movable rod through a fixed hole.

[0019] In one embodiment, each mounting arm is provided with a guide groove extending in a vertical direction, and the first adjustment assembly further includes:

[0020] A rotating element, rotatably mounted on a movable rod about a second horizontal direction, and at least partially confined within a guide groove; and

[0021] The first driving element is mounted on the moving rod and connected to the rotating element via a transmission mechanism. The first driving element is used to drive the rotating element to rotate so as to roll along the guide groove.

[0022] In one embodiment, the first adjustment component further includes a rotary drive, and the second adjustment component is drively connected to the rotary drive, and the second adjustment component rotates about the vertical direction under the drive of the rotary drive.

[0023] In one embodiment, the second adjustment component includes:

[0024] The second adjusting seat is connected to the rotary drive component, and the transmission rod passes through the second adjusting seat along the first horizontal direction;

[0025] The second drive component is mounted on the second adjustment seat; and

[0026] The second transmission component is connected to the second driving component and meshes with the transmission rod. Under the drive of the second driving component, the second transmission component can drive the transmission rod to reciprocate along the first horizontal direction.

[0027] In one embodiment, the sampling device further includes a protective device, which includes:

[0028] The protective fixing base is installed on the second adjustment assembly;

[0029] Protective components are located on one side of the protective mounting base; and

[0030] The protective drive component is mounted on the protective mounting base and connected to the protective component via a transmission. The protective drive component is used to drive the protective component to reciprocate along the second horizontal direction.

[0031] When the sampling rod is in the second state, the protective element is located below at least part of the sampling rod.

[0032] In one embodiment, the sampling groove of the sampling rod extends spirally along the axial direction of the sampling rod.

[0033] In one embodiment, the furnace body is rotatably connected to the mounting arm about a first horizontal direction, and the sampling device further includes a furnace body drive component, which is mounted on the mounting arm and driven to the furnace body, and is used to drive the furnace body to rotate about the first horizontal direction.

[0034] The aforementioned sampling device allows the sampling rod to extract sample materials from the furnace body through the sampling slot. Driven by structures such as the first and second adjustment components, it can be raised and lowered relative to the furnace body in the vertical direction, and can also move relative to the furnace body in the first horizontal direction and rotate around the second horizontal direction. This improves the efficiency and flexibility of the sampling process, effectively collecting sample materials from all layers inside the furnace body. It provides more comprehensive and accurate data support for production monitoring, quality control, and process optimization of industrial silicon submerged arc furnaces, thereby promoting technological progress and production efficiency improvement in related industries.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1 One embodiment of this application provides a sampling device 100 for obtaining sample materials in a submerged arc furnace.

[0051] The sampling device 100 includes a hanger 110, a furnace body 120, a first adjustment component 130, a second adjustment component 140, and a sampling rod 150.

[0052] Among them, the hanger 110 includes two in the first horizontal direction (i.e. Figure 1 Mounting arms 114 are spaced apart on the X direction (as shown), and the furnace body 120 is mounted between two mounting arms 114.

[0053] The first adjustment component 130 is in the vertical direction (i.e.) Figure 1 The first adjustment assembly 130 is mounted on the mounting arm 114 (shown in the Z direction) and located above the furnace body 120. The second adjustment assembly 140 is mounted on the first adjustment assembly 130. The second adjustment assembly 140 includes a transmission rod 141 that can move along the first horizontal direction.

[0054] Sampling rod 150 is installed at one end of transmission rod 141. Sampling groove 150a is formed on the outer surface of sampling rod 150. Sampling rod 150 can be controlled to rotate around a second horizontal direction intersecting the first horizontal direction (i.e., Figure 5 The device can rotate (in the Y direction shown) and switch between a vertically extending first state and a horizontally extending second state. In a preferred embodiment, the first horizontal direction, the second horizontal direction, and the vertical direction are mutually perpendicular.

[0055] Thus, the sampling rod 150 is initially positioned above the furnace body 120 and in a vertically extended first state. Then, driven by the second adjusting component 140, it can move along a second horizontal direction. Afterward, driven by the first adjusting component 130, it can descend vertically to extend into the furnace body 120. Once sampling is complete, the sampling rod 150 rotates to a horizontally extended second state to leave the furnace body 120, allowing the operator to obtain sample material from the sampling slot 150a of the sampling rod 150.

[0056] The aforementioned sampling device 100, with its sampling rod 150, can extract sample materials from the furnace body 120 through the sampling slot 150a. Driven by structures such as the first adjustment component 130 and the second adjustment component 140, the sampling rod 150 can not only rise and fall relative to the furnace body 120 in the vertical direction, but also move relative to the furnace body 120 in the first horizontal direction and rotate around the second horizontal direction. This improves the efficiency and flexibility of the sampling process, effectively collecting sample materials from all levels within the furnace body 120. This provides more comprehensive and accurate data support for production monitoring, quality control, and process optimization of industrial silicon submerged arc furnaces, thereby promoting technological progress and production efficiency improvement in related industries.

[0057] Please continue reading. Figure 1 The hanger 110 has a roughly "door" shaped structure, including a crossbeam 112 extending along a first horizontal direction, and two mounting arms 114 respectively mounted at opposite ends of the crossbeam 112 in the first horizontal direction. One end of each mounting arm 114 is connected to the crossbeam 112, and the other end extends downwards in a vertical direction. It is understood that the structure of the hanger 110 is not limited to this and can be configured as needed to meet different requirements.

[0058] Furthermore, the hanger 110 also includes two guide members 116, each guide member 116 being installed on one side of one mounting arm 114 facing the other mounting arm 114. Each guide member 116 extends vertically and has a guide groove 116a extending vertically. The guide groove 116a is used to guide the lifting and lowering of the first adjustment component 130 in the vertical direction.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the first adjustment assembly 130 includes a first adjustment seat 131, two guide rods 132, two moving rods 133, and two toggle members 134.

[0060] The first adjustment seat 131 has a rectangular plate structure and is located between two mounting arms 114. The first adjustment seat 131 has a connecting groove 131a on each of its opposite sides in the first horizontal direction and the connecting groove 131a extends along the first horizontal direction.

[0061] Two guide rods 132 are respectively fixed in two connecting slots 131a, thus being spaced apart on opposite sides of the first adjusting seat 131 along the first horizontal direction, and each guide rod 132 extends along the first horizontal direction to pass through the connecting slot 131a. One end of each moving rod 133 is correspondingly sleeved on a guide rod 132, and the other end of each moving rod 133 is correspondingly limited to a mounting arm 114. The moving rod 133 can move relative to the guide rod 132 in the first horizontal direction.

[0062] One end of each toggle 134 is connected to the moving rod 133, and the other end of each toggle 134 can extend through the groove wall of the connecting groove 131a and out of the first adjusting seat 131.

[0063] Thus, the operator can push the actuating member 134 along the first horizontal direction to move the moving rod 133 relative to the guide rod 132 in the first horizontal direction, thereby adjusting the engagement length between the moving rod 133 and the guide rod 132, and finally adjusting the length of the first adjusting component 130 in the first horizontal direction so that the length of the first adjusting component 130 in the first horizontal direction matches the distance between the two mounting arms 114 and is limited to the two mounting arms 114.

[0064] Further, in some embodiments, each movable rod 133 has at least two fixing holes, and all fixing holes are spaced apart along the first horizontal direction. The first adjustment assembly 130 also includes two fixing pieces 135 and two fasteners 136. The two fixing pieces 135 are respectively protruding from the opposite end faces of the first adjustment seat 131 in the first horizontal direction. One end of each fastener 136 is limited to the fixing piece 135, and the other end of the fastener 136 is limited to a movable rod 133 through a fixing hole.

[0065] Thus, when the first adjustment component 130 is adjusted to the preset length, the moving rod 133 and the guide rod 132 can be fixed by inserting the fastener 136 into the fixing hole.

[0066] Please combine Figures 1 to 3 As shown, in some embodiments, the first adjustment assembly 130 further includes two first driving members 137 and two rotating members 138. Each rotating member 138 is rotatably mounted to a moving rod 133 about a second horizontal direction, and the rotating member 138 is at least partially confined within a guide groove 116a, with its outer circumferential surface contacting the groove wall of the guide groove 116a. Each first driving member 137 is correspondingly mounted to one end of a moving rod 133, confined to a mounting arm 114, and is drively connected to the rotating member 138. The first driving member 137 is used to drive the rotating member 138 to rotate so as to roll along the guide groove 116a.

[0067] In one specific embodiment, the first driving component 137 can be a drive motor, and the rotating component 138 can be a roller. The main body of the drive motor is fixedly mounted on the moving rod 133, and the output shaft of the drive motor extends along the first horizontal direction. The rotating component 138 is fixedly sleeved on the output shaft of the drive motor so as to rotate under the drive of the drive motor. As a preferred embodiment, the outer surface of the rotating component 138 can have a large roughness so as to have a large frictional force with the groove wall of the guide groove 116a, thereby making the first adjusting component 130 rise and fall stably in the vertical direction.

[0068] Please see Figure 1 , Figure 4 As shown, in some embodiments, the first adjustment component 130 further includes a rotary drive component 139, which is mounted on the first adjustment seat 131. The second adjustment component 140 is connected to the rotary drive component 139. The second adjustment component 140 rotates in the vertical direction under the drive of the rotary drive component 139, thereby changing the angle of the sampling rod 150.

[0069] In one specific embodiment, the rotary drive 139 is a drive motor. The main body of the drive motor is installed in the first adjustment seat 131. The output shaft of the drive motor extends vertically out of the first adjustment seat 131 to connect to the second adjustment component 140, thereby driving the second adjustment component 140 to rotate around the vertical direction.

[0070] In some embodiments, the second adjustment assembly 140 includes, in addition to the transmission rod 141, a second adjustment seat 142, a second drive member, and a second transmission member 144.

[0071] The second adjusting seat 142 is connected to the rotary drive 139 and can rotate vertically under the drive of the rotary drive 139. The transmission rod 141 has a long rod-shaped structure and passes through the second adjusting seat 142 along the first horizontal direction. The transmission rod 141 has a rod-shaped structure extending along the first horizontal direction. The outer wall of one end of the transmission rod 141 is provided with a thread extending along the first horizontal direction. The sampling rod 150 is connected to the other end of the transmission rod 141.

[0072] The second driving component is mounted on the second adjusting seat 142, and the second transmission component 144 is connected to the second driving component. The second transmission component 144 is a gear and meshes with the transmission rod 141. Under the drive of the second driving component, the second transmission component 144 can drive the transmission rod 141 to reciprocate along the first horizontal direction. Specifically, in one embodiment, the second driving component is a drive motor. The main body of the drive motor is fixedly mounted on the second adjusting seat 142, the output shaft of the drive motor extends along the second horizontal direction, and the second transmission component 144 is fixedly sleeved on the output shaft.

[0073] Thus, the second driving member can drive the second transmission member 144 to rotate around the second horizontal direction. Since the second transmission member 144 meshes with the transmission rod 141, the rotation of the second transmission member 144 in turn drives the transmission rod 141 to move along the first horizontal direction.

[0074] Please continue reading. Figure 1 , Figure 4 The transmission rod 141 is also provided with a sampling rod fixing seat 145 at one end, and one end of the sampling rod 150 is rotatably mounted on the sampling rod fixing seat 145 around the second horizontal direction. The second adjustment assembly 140 also includes a sampling rod drive 146, which is mounted on the sampling rod fixing seat 145 and driven to the sampling rod 150, thereby driving the sampling rod 150 to rotate around the second horizontal direction to switch between the first state and the second state.

[0075] In one specific embodiment, the sampling rod drive 146 is a drive motor, the main body of the drive motor is mounted on the sampling rod fixing seat 145, the output shaft of the drive motor extends along the second horizontal direction, and one end of the sampling rod 150 is fixedly sleeved on the output shaft of the drive motor.

[0076] Thus, driven by the first adjustment component 130, the sampling rod 150 can move up and down vertically to occupy different positions in the vertical direction. Driven by the rotation drive component 139, the sampling rod 150 can rotate around the vertical direction to occupy different angles. Driven by the second drive component, the sampling rod 150 can move along the first horizontal direction to occupy different positions in the first horizontal direction. Driven by the sampling rod drive component 146, the sampling rod 150 can rotate around the second horizontal direction to switch between the first and second states. Therefore, the sampling rod 150 has flexibility at different angles, thereby meeting different sampling needs.

[0077] like Figure 1 , Figure 5 As shown, in some embodiments, the sampling device 100 also includes a protective device 160. When the sampling rod 150 is rotated to the second state, the protective device 160 can at least partially cover the area below the sampling rod 150, thereby effectively preventing the sample material on the sampling rod 150 from dripping and causing an accident during the sample collection process, making the operation of the sampling device 100 safer.

[0078] Specifically, in some embodiments, the protective device 160 includes a protective fixing base 161, a protective component 163, and a protective driving component 165.

[0079] A protective mounting base 161 is installed on the side of the second adjusting base 142 of the second adjusting assembly 140 facing the furnace body 120. A protective member 163 is disposed on one side of the protective mounting base 161 in the second horizontal direction. A protective drive member 165 is installed on the other side of the protective mounting base 161 in the horizontal direction. The output shaft of the protective drive member 165 passes through the protective mounting base 161 along the second horizontal direction and is connected to the protective member 163. The protective drive member 165 is used to drive the protective member 163 to reciprocate along the second horizontal direction. When the sampling rod 150 is in the second state, the protective member 163 is located below at least a portion of the sampling rod 150.

[0080] In one specific embodiment, the protective drive component 165 is a cylinder. The cylinder body is mounted on one side of the protective fixing seat 161 in the second horizontal direction, and the output shaft of the cylinder passes through the protective fixing seat 161 in the second horizontal direction and is connected to the protective component 163.

[0081] Please refer to it again. Figure 1 , Figure 4 In some embodiments, the sampling rod 150 has a hollow, long rod-like structure, and the sampling groove 150a of the sampling rod 150 extends spirally along the axial direction of the sampling rod 150. In this way, sample materials at different depths in the furnace body 120 can adhere to different positions in the sampling groove 150a, thereby solving the problem of limited sample acquisition range.

[0082] As a preferred embodiment, the sampling rod 150 is made of silicon carbide. The sampling rod 150 has a high temperature resistance of 1600℃-1800℃, a room temperature bending strength ≥300 MPa, and maintains high hardness even at high temperatures. Furthermore, the sampling rod 150 exhibits strong chemical stability against components such as Al2O3 and CaO in the molten slag, is not prone to reactive adhesion, and also has a low coefficient of thermal expansion (4.5×10⁻⁶). -6 The sampling rod (150mm diameter) exhibits excellent thermal shock resistance and is not easily cracked under repeated thermal cycles, thus meeting the requirements of sampling operations. It is understood that the material of the sampling rod 150 is not limited to this and can be configured to meet different requirements.

[0083] In some embodiments, the furnace body 120 is rotatably connected to the mounting arm 114 about a first horizontal direction. The sampling device 100 also includes a furnace body drive 170, which is mounted on one of the mounting arms 114 and driven to the furnace body 120. The furnace body drive 170 is used to drive the furnace body 120 to rotate about the first horizontal direction to adjust the angle of the furnace body 120. Specifically, in one embodiment, the furnace body drive 170 is a drive motor. The main body of the drive motor is mounted on the mounting arm 114, and the output shaft of the drive motor extends along the first horizontal direction to be driven to the furnace body 120.

[0084] The working principle of the above-mentioned sampling device 100 is as follows:

[0085] First, the two guide members 116 are respectively installed on the two mounting arms 114. Then, the toggle member 134 is moved to move the moving rod 133 along the guide rod 132 to adjust the length of the first adjustment component 130 in the first horizontal direction, so that the first adjustment component 130 is limited between the two mounting arms 114. Then, the moving rod 133 and the guide rod 132 are fixed to each other by the fastener 135, thereby completing the installation of the sampling device 100.

[0086] The first drive member 137, mounted on the moving rod 133, can drive the rotating member 138 to rotate. The rotating member 138 rolls along the guide groove 116a to realize the lifting and lowering of the first adjusting component 130, thereby adjusting the depth of the sampling rod 150 entering the furnace body 120. The rotation drive member 139, mounted on the first adjusting seat 131, can drive the second adjusting component 140 to rotate, thereby adjusting the angle at which the sampling rod 150 enters the furnace body 120. The second drive member, mounted on the second adjusting seat 142, can drive the transmission rod 141 to move along the first horizontal direction, thereby adjusting the position of the sampling rod 150 in the second horizontal direction.

[0087] After sampling is completed, the sampling rod 150 can be switched from a vertically extended first state to a horizontally extended second state by the sampling rod drive 146. Then, the protective drive 165 can drive the protective member 163 to move along the second horizontal direction to be located below the sampling rod 150 to prevent the sample material on the sampling rod 150 from dripping.

[0088] The sampling device 100 described above can adjust the sampling rod 150 in different directions, enabling precise sampling of the sampling rod 150 at different depths within the furnace body 120. This ensures the efficiency and flexibility of the sampling process and also prevents the extracted sample material from dripping and causing safety accidents, making the operation of the sampling device 100 safer.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
