Description

Technical Field

[0001] The utility model belongs to the technical field of silicon production sampling inspection, and specifically relates to a high-temperature resistant sampling inspection device. Background Art

[0002] Metallurgical silicon is widely used in industries such as metallurgy, chemical engineering, and electronics. Its traditional production method is to smelt it from silica and carbonaceous materials in a submerged arc furnace. Other elements brought into the furnace with the burden are reduced while reducing silicon and are incorporated into the silicon solution. Therefore, there are various impurities in metallurgical silicon. The presence of these impurities seriously affects the performance, use, and value of metallurgical silicon. Therefore, controlling the impurity content in metallurgical silicon to improve the purity of metallurgical silicon and thus improve the enterprise's benefits has increasingly become the focus of work in metallurgical silicon production.

[0003] Generally, by carefully selecting raw materials, carefully operating, and controlling appropriate process systems, metallurgical silicon that meets the requirements for preparing aluminum-silicon alloys in metallurgy and mechanical manufacturing industries can be smelted in an electric furnace. However, when the quality of raw materials is poor, or when used to produce special steel, silicon for chemical industry, silicon for electronics, and certain new materials, the metallurgical silicon smelted in an electric furnace often fails to meet the quality requirements and needs to be refined and purified outside the furnace.

[0004] In the prior art, refining and purification outside the furnace usually involves introducing a mixed gas of oxygen and air into the silicon ladle, so that the impurities in the silicon solution react with oxygen to form oxides and enter the slag phase. During the refining process, workers often use iron rods to quickly dip into the high-temperature silicon liquid, and observe the smoothness of the solidified silicon water sample after the silicon liquid cools to judge the degree of refining. However, manual sampling has great potential safety hazards and is easy to scald the staff. Summary of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and title of the specification of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A high-temperature resistant sampling inspection device includes a sampling rod inserted into the high-temperature silicon liquid for sampling. A connecting collar is detachably connected to the outer wall of the sampling rod. A connecting rod is fixedly connected to the outer wall of the connecting collar. A rotating shaft body is inserted at the end of the connecting rod. The rotating shaft body is rotationally connected to the inside of a support column in an embedded manner. An adjusting mechanism is installed at the top of the support column. The adjusting mechanism rotates the rotating shaft body, and thus rotates the sampling rod through the connecting rod and the connecting collar, presenting a vertical or parallel state to the ground.

[0008] Preferably, the bottom of the support column is rotatably connected to a support base, and a rotation mechanism is installed at the upper end of the support base. The rotation mechanism rotates the support column, and thus can drive the sampling rod to rotate around the center point of the support column.

[0009] Preferably, the sampling rod is hollow inside, a second semi-circular groove is provided at the inner bottom of the sampling rod, an inner rod is provided inside the sampling rod, the inner rod is hollow inside and a first semi-circular groove is provided on the outer wall near the bottom. The bottom of the inner rod passes through the second semi-circular groove, and the part of the inner rod passing through the bottom of the sampling rod samples the high-temperature silicon liquid.

[0010] Preferably, the inner rod is slidably connected to the inside of the sampling rod, and the inner rod moves outward to adjust the length of the inner rod extending out of the bottom of the sampling rod.

[0011] Preferably, a third driving motor is detachably connected to the top of the sampling rod. The rotating end of the third driving motor is inserted into the inside of the sampling rod and is detachably connected to a threaded rod. The threaded rod is threadedly connected to the end of the inner rod, and the threaded rod is rotatably connected to the inside of the sampling rod. The third driving motor rotates to drive the threaded rod to rotate, thereby causing the inner rod to slide inside the sampling rod.

[0012] Preferably, the adjusting mechanism includes a first driving motor, a first gear and a second gear. One end of the rotating shaft body away from the connecting rod passes through the support column, and the second gear is fixedly connected to the passing end of the rotating shaft body. The first driving motor is detachably connected to the upper end of the support column, the first gear is connected to the rotating end of the first driving motor, the first gear meshes with the second gear, and the first driving motor rotates to make the first gear rotate.

[0013] Preferably, the rotation mechanism includes a third gear, a second driving motor and a fourth gear. The fourth gear is fixedly connected to the outer wall of the support column, the second driving motor is connected to the upper end of the support base through a mounting bracket, the third gear is connected to the rotating end of the second driving motor, the third gear meshes with the fourth gear, and the second driving motor rotates to make the third gear rotate. Through meshing, the fourth gear drives the support column to rotate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. Through the setting adjustment mechanism and rotating mechanism, the first drive motor rotates to rotate the first gear, and the second gear drives the rotating shaft to rotate through meshing, so that the verticality and parallelism of the sampling rod can be automatically adjusted, making sampling more convenient. The second drive motor drives the third gear to rotate, and the meshing with the fourth gear makes the support column rotate, so that the sampling rod can rotate when it is in a parallel state, and the sampling rod is located above the high-temperature silicon liquid. After the sampling of the sampling rod is completed, the second drive motor rotates to separate the sampling rod from the high-temperature silicon liquid, which can save manpower and make it more convenient to observe the shape of the high-temperature silicon liquid after cooling;

[0016] 2. The bottom of the built-in rod is provided with a second semicircular groove, and the built-in rod is extended from the inside of the sampling rod, so that when the sampling rod is inserted into the high-temperature silicon liquid in a vertical state, the built-in rod is also inserted into the high-temperature silicon liquid in a vertical state. At this time, the sampling rod and the built-in rod are rotated to a parallel state through the adjustment mechanism. At this time, the built-in rod at the first semicircular groove exceeding the length of the sampling rod is filled with high-temperature silicon liquid, making sampling more convenient and preventing inaccurate detection data due to insufficient sampling;

[0017] 3. The threaded rod is rotated by rotating the third driving motor, so that the extension length of the built-in rod can be conveniently controlled. When the liquid level of the high-temperature silicon liquid is low, the built-in rod can be extended to ensure that it has enough length to be inserted into the high-temperature silicon liquid.

[0026] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments. The present utility model provides the following embodiments.

[0029] As Figure 1-2 shown, it is a schematic structural diagram of a high-temperature sampling inspection device and a rotating shaft body according to a preferred embodiment of the present utility model. The high-temperature sampling inspection device of this embodiment includes a support base 109. A support column 105 is installed at the upper end of the support base 109. A rotating shaft body 110 is embedded and rotatably connected to the outer wall of one side of the support column 105. A connecting rod 101 is inserted into the rotating shaft body 110. A connecting sleeve ring 100 is fixedly connected to the end of the connecting rod 101. A sampling rod 200 for sampling is detachably connected inside the connecting sleeve ring 100. Rotate the rotating shaft body 110 to make the sampling rod 200 in a state parallel to the ground. Move the device towards the high-temperature silicon liquid direction, then rotate the rotating shaft body 110 to insert the sampling rod 200 into the high-temperature silicon liquid and quickly rotate back to make the sampling rod 200 adhere to the high-temperature silicon liquid, and then move the device backward, thereby being able to complete the sampling of the silicon liquid, and thus being able to avoid the occurrence of danger caused by manually holding the sampling rod 200 for sampling.

[0030] As Figure 1As shown, in order to enable the sampling rod 200 to automatically rotate and adjust to be vertical or parallel, in this embodiment, one end of the rotating shaft body 110 away from the connecting rod 101 passes through the support column 105 and is fixedly connected with a second gear 104 at the passing end. The upper end of the support column 105 is detachably connected with a first driving motor 102, and the rotating end of the first driving motor 102 is detachably connected with a first gear 103 meshing with the second gear 104. When the first driving motor 102 rotates, the first gear 103 rotates, and through meshing, the second gear 104 drives the rotating shaft body 110 to rotate, so as to automatically adjust the vertical and parallel states of the sampling rod 200, making sampling more convenient.

[0031] It should be noted that the above-mentioned first driving motor 102, first gear 103 and second gear 104 are the adjusting mechanisms in this embodiment. The adjusting mechanism includes but is not limited to the first driving motor 102, first gear 103 and second gear 104. As long as it is a mechanism that can make the rotating shaft body 110 rotate, it can be applied to this embodiment.

[0032] As Figure 2 shown, in order to avoid the need for manual frequent movement of the equipment during sampling, in this embodiment, the support column 105 is rotatably connected to the support base 109, and a fourth gear 108 is fixedly connected to the outer wall of the support column 105. The upper end of the support base 109 is detachably connected with a second driving motor 107 through a mounting bracket, and the rotating end of the second driving motor 107 is fixedly connected with a third gear 106 meshing with the fourth gear 108. Place the support base 109 close to the high-temperature silicon liquid. By rotating the second driving motor 107 to drive the third gear 106 to rotate, and cooperating with the meshing with the fourth gear 108, the support column 105 rotates, so that it can rotate when the sampling rod 200 is in a parallel state, place the sampling rod 200 above the high-temperature silicon liquid. After the sampling rod 200 finishes sampling, the second driving motor 107 rotates back, so that the sampling rod 200 can be separated from above the high-temperature silicon liquid, which can save manpower and is more convenient to observe the shape of the high-temperature silicon liquid after cooling.

[0033] It should be noted that the above-mentioned third gear 106, second driving motor 107 and fourth gear 108 are the rotating mechanisms in this embodiment. The rotating mechanism includes but is not limited to the third gear 106, second driving motor 107 and fourth gear 108. As long as it is a mechanism that can make the support column 105 rotate, it can be applied to this embodiment.

[0034] As Figure 3 、 Figure 4 and Figure 5 shown, which are the sampling rod, the sectional view of the sampling rod, and Figure 4The enlarged structural schematic diagram at point A in the middle shows that the interior of the sampling rod 200 is hollow, and a second semicircular groove 205 is provided at the inner bottom, the interior of the second semicircular groove 205 is slidably connected with a built-in rod 201, the interior of the built-in rod 201 is hollow, and a first semicircular groove 202 is provided on the outer wall, the bottom of the built-in rod 201 passes through the second semicircular groove 205, and the built-in rod 201 extends from the interior of the sampling rod 200, so that when the sampling rod 200 is inserted into the high-temperature silicon liquid in a vertical state, the built-in rod 201 is also inserted into the high-temperature silicon liquid in a vertical state. At this time, the sampling rod 200 and the built-in rod 201 are rotated to a parallel state through the adjustment mechanism. At this time, the interior of the built-in rod 201 at the first semicircular groove 202 that exceeds the length of the sampling rod 200 is filled with high-temperature silicon liquid, which makes sampling more convenient and can prevent inaccurate detection data due to insufficient sampling.

[0035] like Figure 3 as well as Figure 4 As shown, in order to facilitate the control of the extension length of the built-in rod 201, in this embodiment, the upper end of the sampling rod 200 is detachably connected to the third driving motor 203, and the rotating end of the third driving motor 203 is inserted into the interior of the sampling rod 200 and is detachably connected to the threaded rod 204, and the threaded rod 204 is threadedly connected to the end of the built-in rod 201. The rotation of the third driving motor 203 causes the threaded rod 204 to rotate, thereby conveniently controlling the extension length of the built-in rod 201. When the liquid level of the high-temperature silicon liquid is low, the built-in rod 201 can be extended to ensure that it has sufficient length to be inserted into the high-temperature silicon liquid.

[0036] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
