Description

Technical Field

[0001] The utility model relates to the field of sampling equipment, in particular to a high-temperature molten salt sampling device. Background Art

[0002] Molten salt electrolysis is of great significance to nonferrous metal smelting. It is widely used in the electrolytic production of light metals and is the primary method for their extraction. The principle is to electrolyze certain metal salts using a melted electrolyte. Metals such as aluminum, calcium, beryllium, lithium, and sodium are all produced using molten salt electrolysis. Many rare metals, such as thorium, niobium, zirconium, and tantalum, can also be produced using molten salt electrolysis.

[0003] During molten salt electrolysis, the composition of the molten salt in different parts of the electrolytic cell can be uneven due to the circulation of the electrolytic cell. Therefore, it is necessary to continuously monitor the composition of the molten salt in each part of the electrolytic cell to determine the electrolytic production status and take appropriate measures. However, due to the high temperature and fluidity of the molten salt, sampling the molten salt in various parts of the electrolytic cell is essential to understand the current production status.

[0004] At present, the sampling methods of molten salt electrolytes can be roughly divided into two types:

[0005] Extraction method: Extend the sampler to the sampling site and use negative pressure to extract the molten salt electrolyte; for example, "CN219416847U" uses a syringe-like device for extraction.

[0006] Inflow method: extend the sampler to the sampling part of the electrolytic cell and open the sampling port. After the electrolyte flows in, close the sampling port to complete the sampling. For example, "CN204903231U" uses a "plug" to block the sampling port for sampling, and "CN220356721U" installs a slider on the cylindrical sampler for sampling.

[0007] The above molten salt electrolyte sampling has the following problems:

[0008] Sealing problems may cause the sample to contain electrolytes from other locations;

[0009] The extraction type suction tube is relatively thin. For example, the molten salt of patent "CN219416847U" may be blocked by molten salt cooling during the extraction process, which will affect the sampling operation.

[0010] The equipment is relatively complex and inconvenient to operate, such as the patented "CN204903231U" device. The complexity of the device also increases the risk of sampling.

[0011] In view of this, the present utility model is proposed. Utility Model Content

[0043] like Figure 1 and Figure 2 As shown, a high-temperature molten salt sampling device provided by an embodiment of the present utility model includes a fixed rod 1, a spoon body 6, a spoon cover 7, an operating rod 8 and a movable part;

[0044] One end of the fixing rod 1 is connected to one end of the spoon body 6;

[0045] The spoon cover 7 is provided on the spoon body 6, and one end of the spoon cover 7 is rotatably connected to the spoon body 6, the other end of the spoon cover 7 is rotatably connected to one end of the movable member, and the other end of the movable member is rotatably connected to one end of the operating rod 8;

[0046] The operating rod 8 and the fixed rod 1 are arranged crosswise, and the intersection of the two is rotatably connected. By manipulating the intersection angle of the operating rod 8 and the fixed rod 1 to increase, the spoon cover 7 can be opened, and vice versa.

[0047] The method for using the high-temperature molten salt sampling device provided in the embodiment of the utility model is as follows:

[0048] When sampling, the staff makes the fixed rod 1 and the operating rod 8 at a small angle, and the spoon cover 7 and the spoon body 6 are closed (such as Figure 1 The closed sampling spoon is extended to the sampling position of the electrolytic cell, and the staff manipulates the fixing rod 1 and the operating rod 8 to a large angle to open the spoon cover 7 (as shown). Figure 2 As shown), the high-temperature molten salt flows into the spoon body 6, and then the staff manipulates the operating rod 8 and the fixed rod 1 to make the intersection angle between the two at a small angle. The spoon cover 7 is pressed down and closed with the spoon body 6. The molten salt sample is sealed in the spoon body 6. Finally, the sampling spoon is raised to obtain the sample.

[0049] The high-temperature molten salt sampling device provided by the present invention can realize sampling from high-temperature molten salt. During the taking-out process, the sample is sealed by the spoon cover 7 in the spoon body 6, which can avoid the risk of scalding caused by splashing of high-temperature molten salt during the sampling process, and can also avoid the risk of composition change during the sampling process; sealing the sample can also prevent samples from other parts from mixing in, which can improve the accuracy of sampling; the device is simple, easy to make, low-cost, and easy to use.

[0050] Optionally, to make the device more convenient to use, the spoon cover 7 and the fixing rod 1 are connected to the same end of the spoon body 6.

[0051] Optionally, an elastic member is connected between the end of the fixing rod 1 away from the spoon body 6 and the end of the operating rod 8 away from the movable member;

[0052] When the angle between the operating rod 8 and the fixed rod 1 becomes smaller, the elastic member exerts a thrust on the fixed rod 1 and the operating rod 8 , so that the angle between the operating rod 8 and the fixed rod 1 tends to increase.

[0053] When the elastic member is provided, the operator only needs to squeeze the ends of the fixed rod 1 and the operating rod 8 to cover the spoon cover 7 on the spoon body 6 and seal the sampling spoon. When the ends of the fixed rod 1 and the operating rod 8 are loosened, the elastic force of the elastic member expands the angle between the fixed rod 1 and the operating rod 8 to open the sampling spoon. Therefore, the provision of the elastic member can make the sampling device more convenient to use.

[0054] Optionally, the elastic member is a spring 9 .

[0055] The spring 9 is a commonly used elastic member that is easy to use. In other embodiments of the present invention, the elastic member may also be a part made of a material with resilience, such as elastic rubber.

[0056] In addition, it should be noted that in order to improve the convenience of use, in addition to setting the elastic part, finger rings can also be set at the ends of the fixed rod 1 and the operating rod 8 respectively. When in use, the staff only needs to pass the thumb and other fingers through the finger rings on the fixed rod 1 and the operating rod 8 to perform gripping and opening actions to open and close the sampling spoon.

[0057] Optionally, a sampling depth mark is provided on the fixing rod 1 .

[0058] When a sampling depth mark is provided on the fixing rod 1 , it is convenient for the user to obtain samples at a target depth according to the indication of the sampling depth mark.

[0059] Optionally, the spoon body 6 has a curved groove bottom 61 and a barrier wall 62. One end of the curved groove bottom 61 is connected to the barrier wall 62, and the other end of the curved groove bottom 61 extends all the way to the spoon mouth. The spoon cover 7 is rotatably connected to the barrier wall 62. When sampling, the sample enters the spoon body 6 along the curved groove bottom 61.

[0060] Optionally, the movable member is a rod or a rope. In the embodiment shown in the figure of the present application, the movable member is a rod.

[0061] Optionally, the rotatable connection is a hinge. Specifically, the spoon cover 7 and the spoon body 6 are hinged via a first hinge connection 5; the spoon cover 7 and the movable member are hinged via a second hinge connection 4; the movable member and the operating rod 8 are hinged via a third hinge connection 3; and the operating lever and the fixed rod 1 are hinged via a fourth hinge connection 2.

[0062] Optionally, the spoon body 6 is a stainless steel spoon body 6, a nickel alloy spoon body 6 or a titanium alloy spoon body 6;

[0063] The spoon cover 7 is a stainless steel spoon cover 7, a nickel alloy spoon cover 7 or a titanium alloy spoon cover 7;

[0064] The movable parts are stainless steel movable parts, nickel alloy movable parts or titanium alloy movable parts;

[0065] The fixing rod 1 is a stainless steel fixing rod 1, a nickel alloy fixing rod 1 or a titanium alloy fixing rod 1;

[0066] The operating rod 8 is a stainless steel operating rod 8 , a nickel alloy operating rod 8 or a titanium alloy operating rod 8 .

[0067] The spoon body 6, spoon cover 7, movable part, fixed rod 1 and operating rod 8 made of the above materials have good high temperature resistance and can ensure that high temperature sampling does not contaminate the sample.

[0068] In summary, the high-temperature molten salt sampling device provided by the utility model has the following advantages:

[0069] (1) Safety: When sampling, high-temperature molten salt is usually scooped out, and the high-temperature molten salt is exposed to the outside, posing a risk of burns. This device adds a controllable closure spoon cover 7 to the sampling spoon. Closing is achieved by a spring 9. When closed, the spoon cover 7 firmly covers the spoon body 6, sealing the molten salt inside the spoon, avoiding the risk of burns caused by splashing high-temperature molten salt during sampling.

[0070] (2) Accuracy: When conventionally sampling high-temperature molten salt using a stainless steel spoon, the molten salt in the spoon moves as the sampling spoon moves, making it impossible to sample the molten salt in a fixed area. This device can be closed for sampling, and the sampling depth mark on the fixed rod 1 confirms the depth of the molten salt taken, preventing the sample molten salt from coming into contact with molten salt in other parts during movement, which may cause changes in composition and ensure sampling accuracy.

[0071] (3) Simplicity of equipment: The equipment has a simple structure, is easy to manufacture and has low cost.

[0072] (4) Convenience of operation: The device of the utility model is simple and easy to understand, easy to operate and highly flexible.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
