Description

Technical Field

[0001] The invention relates to the technical field of lithium carbonate production, in particular to drying detection sampling equipment for battery-grade lithium carbonate production. Background Art

[0002] In the later stage of water immersion, the drying detection sampling equipment for battery-grade lithium carbonate production mainly relies on filtering and drying equipment (such as filter presses, centrifuges, ovens, fluidized bed dryers, etc.) to obtain battery-grade lithium carbonate products; among them, fluidized bed dryers are more commonly used; it should be noted that if the dried battery-grade lithium carbonate fails to meet the process requirements, the operation of the entire water immersion production line will lose its meaning and become worthless.

[0003] The Chinese publication number is CN217717110U, and the name is sampling device and fluidized bed dryer. It mentions that "the material enters the fixed sleeve 10 from the material container, and then flows through the sampling sleeve 20 from the discharge port 11 of the fixed sleeve 10 into the sampling bag 30. When the amount of material in the sampling bag 30 reaches the sampling requirement, a sealing machine is used to seal the side of the sampling bag 30 away from the material, and the sampling bag 30 is divided into two parts, one part is a bag body containing material near the bottom (referred to as "sample bag" in the following description), and the other part is a bag body near the top without material or with a small amount of material. Subsequently, a cutting tool such as scissors is used to cut along the sealing area to separate the two parts of the bag body."

[0004] However, the above disclosed patents and the devices in the prior art have the following problems in actual use.

[0005] 1. The above-mentioned patents only divide the samples sampled once into bags during sampling, which does not effectively meet the sampling randomness requirement. At the same time, the bagging after direct filling sampling cannot effectively meet the requirements of proportional sampling comparison. This unequal ratio, interval / random sampling method is not representative, which is not conducive to subsequent material analysis, because the properties of the material may be different in different parts. If the sampling is not representative, the analysis results cannot accurately reflect the true situation of the entire material. For example, if the particle size, density, etc. are not sampled representatively, it will lead to wrong conclusions, which will affect the subsequent production process and product quality.

[0006] 2. Whether the above-mentioned public patents and existing sampling operations can effectively guarantee the normal operation of production equipment during sampling still needs to be improved; during the sampling process, due to the unreasonable design of the sampling device, opening the sampling port will cause the air flow channel in the fluidized bed to change, the local air flow speed to accelerate, turbulence to form, and the originally stable air flow distribution to be disturbed, thereby affecting the fluidization state of the material. Some materials may not be able to obtain sufficient air flow support due to unstable air flow, and cannot be fully fluidized, resulting in accumulation or uneven distribution, which in turn leads to uneven drying; at the same time, the sampling operation will also cause pressure fluctuations in the fluidized bed, and unstable pressure will also cause changes in the air flow force acting on the material, resulting in unstable fluidization state of the material, accumulation or uneven distribution, resulting in unstable and uneven drying process.

[0007] Therefore, we proposed dry detection sampling equipment for battery-grade lithium carbonate production to solve the above problems. Summary of the invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose a drying detection sampling device for battery-grade lithium carbonate production to solve the problems existing in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: a drying detection sampling device for battery-grade lithium carbonate production, comprising: a fluidized bed dryer, an output pipe, the output pipe is fixedly connected to the fluidized bed dryer, and further comprising: a first component, a second component, and a third component, the second component is located in the middle of the first component, and the third component is located below the first component;

[0010] The first component is used to ensure stable collection of lithium carbonate samples during sampling and testing;

[0011] The second component is used for random, proportional and interval sampling of lithium carbonate;

[0012] The third component is used to transfer the lithium carbonate sample after sampling and to assist in understanding its fluidity.

[0013] Preferably, the first component includes a T-shaped sliding member slidably connected to the output pipe, the bottom end of the T-shaped sliding member is fixedly connected to a material transfer member, a transfer through groove is provided on the material transfer member, and the bottom end of the material transfer member is fixedly connected to a main shell.

[0014] Preferably, the circumferential side wall of the main body shell is equidistantly fixedly connected with guide spring columns, the guide spring columns are laterally slidably connected with a ratchet piece A, and the center of the inner surface of the ratchet piece A is fixedly connected with an auxiliary spring body.

[0015] Preferably, a magnet bar is fixedly connected to the upper portion of the ratchet plate A, and a magnetic guide member is provided in the transfer groove.

[0016] Preferably, the second component includes a driving shaft fixedly connected in the main body shell, a rotating wheel disc is fixedly connected to the driving shaft, arc-shaped supporting grooves are equidistantly provided around the circumference of the rotating wheel disc, a ratchet piece B is fixedly connected to one side of the rotating wheel disc, and one end of the auxiliary spring body away from the ratchet piece A is fixedly connected to the ratchet piece B.

[0017] Preferably, a through sampling groove is provided on the upper portion of the main body shell, the sampling groove and the transfer groove overlap, and a through transfer groove is provided on the bottom portion of the main body shell.

[0018] Preferably, the third component includes a lithium carbonate receiving body fixedly connected to the bottom end of the main shell and communicated with the main shell, an auxiliary block is fixedly sleeved on the lithium carbonate receiving body, a column is fixedly connected to the auxiliary block, a material silo is rotatably connected to the column, and a threaded fastener is threadedly connected to the column.

[0019] Preferably, the guide spring column consists of a spring and a guide rod.

[0020] Preferably, the magnetic strips and the magnetic guide members have the same magnetic poles on opposite sides, and the magnetic guide members are composed of a cross bar, a spring and a magnetic guide sheet.

[0021] Preferably, the ratchet piece B, the main body shell and the arc-shaped supporting groove can form a temporary material storage bin.

[0022] Compared with the prior art, the present invention provides a drying detection sampling device for battery-grade lithium carbonate production, which has the following beneficial effects:

[0023] 1. The sampling method in the prior art is relatively simple, and the accuracy of sampling cannot be effectively achieved. In this regard, the design of the present application can extract samples randomly, proportionally, and at intervals during the sampling process of lithium carbonate production, thereby improving the accuracy of analysis after sampling. More specifically, by controlling the rotation speed of the drive shaft, the arc-shaped support groove can collect the transported lithium carbonate material in different time periods, and because the capacity of the arc-shaped support groove remains unchanged, it is different from the random sealing of the sampling bag in the above-mentioned document. This design has many advantages. Random sampling can fully reflect the overall situation and discover potential problems; proportional sampling can accurately evaluate the proportion of components and facilitate quality control; interval sampling can monitor changes in the production process and optimize the production process. That is, the accuracy of analysis after sampling is improved through this design, providing a more reliable basis for quality control and optimization of lithium carbonate production.

[0024] 2. In the existing sampling process, opening the sampling port will cause changes in the airflow channel in the fluidized bed, accelerate the local airflow speed, form turbulence, disrupt the originally stable airflow distribution, affect the fluidization state of the material, and then cause uneven drying; in addition, the sampling operation may also cause pressure fluctuations in the fluidized bed, resulting in unstable fluidization state of the material, accumulation or uneven distribution. In this regard, the present application can effectively reduce the airflow changes in the fluidized bed during the sampling process of lithium carbonate production; more specifically, the present application forms a temporary material storage bin through the ratchet piece B, the main body shell and the arc-shaped support groove, which reduces the interference with the airflow in the fluidized bed during the sampling process, avoids the acceleration of the local airflow speed and the formation of turbulence due to its airflow disturbance, maintains the originally stable airflow distribution, and provides a guarantee for the good fluidization of the material;

[0025] 3. The arc-shaped design of the arc-shaped supporting groove in the present application can form a temporary material storage bin in cooperation with the ratchet piece B and the main body shell, thereby realizing the equal collection and transfer of materials; the arc-shaped supporting groove adopts an arc-shaped design, and the arc surface reversal method is adopted in the final step of transferring lithium carbonate, so that in the process of material transfer, the lithium carbonate material can be effectively prevented from adhering to the transfer position of the arc surface due to insufficient drying, which is in sharp contrast to the material adhesion problem existing in the existing material transfer, and avoids the situation where the amount of transferred and collected materials is lower than the normal process requirements due to material adhesion, thereby improving the effectiveness and accuracy of subsequent analysis.

[0026] 4. In the present application, the auxiliary block and the threaded fastener are designed to be rotatably connected through a column rod. On the one hand, it can effectively adjust the inclination angle of the material silo to assist the filling operation of the sampling work; on the other hand, it can specifically adjust the material silo to different angles, such as 30°, 60°, etc.; through such adjustment, the fluidity of the lithium carbonate material transferred from the material silo can be observed, and then it can be evaluated whether the fluidity in this state is conducive to the subsequent transportation and processing of the lithium carbonate material. This can avoid the lithium carbonate material being misjudged as qualified due to poor fluidity, thereby avoiding blockage and adhesion problems during the transportation process, greatly improving the quality reliability of the lithium carbonate material production.

[0057] For further examples, please refer to Figures 1 to 7 As shown:

[0058] The second component 4 is used for random, proportional and interval sampling of lithium carbonate;

[0059] The third component 5 is used to transfer the lithium carbonate sample after sampling and assist in understanding its fluidity;

[0060] The second component 4 includes a driving shaft 401 fixedly connected to the main body shell 304, a rotating wheel 402 fixedly connected to the driving shaft 401, arc-shaped supporting grooves 403 are equidistantly provided on the circumference of the rotating wheel 402, a ratchet piece B404 is fixedly connected to one side of the rotating wheel 402, one end of the auxiliary spring body 307 away from the ratchet piece A306 is fixedly connected to the ratchet piece B404, a through sampling groove 405 is provided on the upper part of the main body shell 304, the sampling groove 405 and the transfer groove 303 are overlapped, and a through transfer groove 406 is provided on the bottom of the main body shell 304;

[0061] The third component 5 includes a lithium carbonate receiving body 501 fixedly connected to the bottom end of the main shell 304 and communicated with the main shell 304, an auxiliary block 502 is fixedly sleeved on the lithium carbonate receiving body 501, the auxiliary block 502 is fixedly connected to a column 503, the column 503 is rotatably connected to a material silo 504, and the column 503 is threadedly connected to a threaded fastener 505.

[0062] in:

[0063] The second component 4 is mainly used for random, proportional and interval sampling of lithium carbonate.

[0064] A marking piece is fixedly connected to the rotating wheel 402 , and a scale bar is fixed to the main body shell 304 . The cooperation of the two can effectively determine the number of rotations of the rotating wheel 402 .

[0065] The arc-shaped supporting groove 403 can realize the equal transfer of lithium carbonate.

[0066] The ratchet piece B404, the main body shell 304 and the arc-shaped supporting groove 403 can form a temporary material storage bin.

[0067] The third component 5 is mainly used to transfer the lithium carbonate sample after sampling and to assist in understanding its fluidity.

[0068] The material silo 504 is a wear-resistant plastic part with strong light transmittance.

[0069] The threaded fastener 505 and the column rod 503 are threadably matched.

[0070] Everything in the above example works like this:

[0071] It should be noted that if sampling is not performed, the output pipe 2 will be blocked by the T-shaped sliding member 301 without a through opening, so as to ensure the normal transportation of the material.

[0072] The following is the working process of the second component 4:

[0073] When in use, the T-shaped sliding member 301 is slidably inserted into the T-shaped sliding groove on the output pipe 2, and the stability after the insertion is ensured by means of the magnetic plug-in member fixedly connected thereto; further, after starting the equipment, the transferred lithium carbonate material will enter the transfer groove 303 provided on the material transfer member 302 while being transferred through the output pipe 2. For details, please refer to the attached Figure 4 And attached Figure 5 , the lithium carbonate material in the transfer slot 303 will fall into the arc-shaped supporting slot 403 provided on the rotating wheel 402 through the sampling slot 405. After the rotating wheel 402 is rotated by controlling the driving shaft 401, the lithium carbonate material falling into the arc-shaped supporting slot 403 will move from a position in the same vertical line as the sampling slot 405 to a position no longer in the same vertical line with the sampling slot 405. It is known that the ratchet piece B404, the main body shell 304 and the arc-shaped supporting slot 403 can form a temporary material storage bin. Therefore, the lithium carbonate material falling into the arc-shaped supporting slot 403 will be gradually transferred under the action of the temporary storage bin, and finally leak out from the transfer slot 406 and move to the lithium carbonate receiving body 501, and a sampling work is completed at this point;

[0074] Furthermore, since the lithium carbonate material is continuously transported from the output pipe 2, the lithium carbonate material in the transfer groove 303 on the material transfer member 302 is in a changing state, that is, in a flowing state, and is not static; therefore, the sampling personnel can control the rotation speed of the drive shaft 401, or control its rotation or stop operation, to achieve intermittent and random sampling operations, thereby ensuring the integrity of the sampling analysis;

[0075] Furthermore, through the arc design of the specific arc-shaped supporting groove 403, in addition to cooperating with the ratchet piece B404 and the main body shell 304, a temporary material storage bin can be formed to achieve the same collection and transfer of materials; moreover, the arc design of the arc-shaped supporting groove 403 and the use of the arc surface reversal method in the final step of transferring lithium carbonate can effectively prevent the lithium carbonate material from adhering to the transfer position of the arc surface due to insufficient drying during the material transfer process, which is in sharp contrast to the material adhesion problem existing in the existing material transfer, and avoids the situation where the amount of transferred and collected materials is lower than the normal process requirements due to material adhesion, thereby improving the effectiveness and accuracy of subsequent analysis.

[0076] Furthermore, the present application performs overlapping small-scale opening processing on the transfer slot 303 and the sampling slot 405, and cooperates with the use of the arc-shaped supporting slot 403. In this way, it can be achieved that each time the arc-shaped supporting slot 403 samples the lithium carbonate in the fluidized bed dryer 1, only a small amount of gas is connected to the sampling device; for details, please refer to the attached Figure 5 At the same time, since the ratchet piece B404, the main body shell 304 and the arc-shaped supporting groove 403 can form a temporary material storage bin, after the material is supported and collected by the arc-shaped supporting groove 403, the gas originally located in the arc-shaped supporting groove 403 will also be forced to move, and the gas transfer is also restricted. This design is different from the traditional sampling method. During traditional sampling, the sampling equipment will leak or disturb the gas in the working equipment. However, due to the contact with a smaller part of the working chamber, this design can effectively reduce the changes in the airflow channel in the fluidized bed caused by sampling, prevent the local airflow speed from accelerating to form turbulence, thereby avoiding disrupting the originally stable airflow distribution, so as not to affect the fluidization state of the material, and prevent the fluidization state of the material from being unstable, and the drying process from being unstable and uneven; further improve the stability of the equipment.

[0077] Please refer to the above working process Figures 1 to 6 .

[0078] The following is the working process of the first component 3:

[0079] Furthermore, when the driving shaft 401 drives the rotating wheel 402 and the arc-shaped supporting groove 403 to rotate, the ratchet piece A306 located on one side of the arc-shaped supporting groove 403 and meshing with it will move under the action of the movement of the arc-shaped supporting groove 403; Figure 8 , the rotating ratchet piece B404 will push the ratchet piece A306 to move away from the material transfer member 302. At this time, the spring on the guide spring column 305 is compressed, and the ratchet piece A306 moves stably laterally with the assistance of the guide rod of the guide spring column 305; as the ratchet piece B404 continues to rotate, once the teeth of the ratchet piece B404 and the ratchet piece A306 no longer abut against each other, the ratchet piece A306 will move towards the material transfer member 302 under the action of the spring in the guide spring column 305, and so on; further, when the ratchet piece A3 When 06 is moving back and forth laterally, the ratchet piece A306 will bring the magnet strip 308 thereon closer to or away from the magnetic guide piece 309. It is known that the magnet strip 308 and the magnetic guide piece 309 have the same magnetic poles on the opposite sides, and the magnetic guide piece 309 is composed of a cross bar, a spring and a magnetic guide piece. Therefore, during the movement of the magnet strip 308, the magnetic guide piece 309 will move back and forth in the transfer slot 303, thereby avoiding the material being transported too fast or the lithium carbonate material that has not been completely dried being blocked during the transportation, so as not to affect the sampling and lithium carbonate material transfer work;

[0080] Please refer to the above working process Figures 8 to 11 .

[0081] The following is the working process of the third component 5:

[0082] When in use, the threaded fastener 505 tightened on the column 503 is reversely screwed, and then the operator can adjust the inclination angle of the material silo 504 with the column 503 as the rotation axis. After the angle adjustment is completed, the threaded fastener 505 is tightened again to tighten the material silo 504;

[0083] Furthermore, in the present application, the auxiliary block 502 and the threaded fastener 505 are designed to rotate through the column 503, which can effectively adjust the inclination angle of the material silo 504 to assist the filling operation of the sampling work; on the other hand, the material silo 504 can be adjusted to different angles, such as 30°, 60°, etc. in a targeted manner; through such adjustment, the fluidity of the lithium carbonate material transferred from the material silo 504 can be observed, and then it can be evaluated whether the fluidity in this state is conducive to the subsequent transportation and processing of the lithium carbonate material. This can avoid the lithium carbonate material being misjudged as qualified due to poor fluidity, thereby avoiding blockage and adhesion problems during the transportation process, greatly improving the quality reliability of the lithium carbonate material production.

[0084] Please refer to the above working process Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 .

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
