[0016] 1. The present invention integrates the sampling device into multiple positions of the rotary kiln.

[0018] 3.

DETAILED DESCRIPTION

[0027] See also Figures 1 to 3 The present invention provides a technical solution: a sampling device for lithium ore rotary kiln detection, comprising a fixed sleeve 1 and a sampling assembly 4, wherein the interior of the fixed sleeve 1 is rotatably connected to the kiln body 2, and a sampling box 3 is arranged at the bottom of the fixed sleeve 1, and the sampling assembly 4 is arranged at the lower part of the fixed sleeve 1, and the sampling assembly 4 comprises a worm 401, an outer peripheral surface of one end of the worm 401 is engaged with a worm wheel 402, and a crankshaft 403 is arranged inside the worm wheel 402, a cam ring 404 is fixed to the outside of one end of the crankshaft 403, and the top of the cam ring 404 is slidably connected to a limit plate 405, and telescopic rods 406 are symmetrically arranged at both ends of the bottom of the limit plate 405, and the telescopic rod 406 is symmetrically arranged at both ends of the bottom of the limit plate 405. 06 is fixedly connected to the sampling box 3, connecting plates 407 are slidably connected to the inside of the two ends of the limiting plate 405, and the connecting plate 407 is rotatably connected to the fixed sleeve 1, a pulley seat 408 is provided on the top of the limiting plate 405, and a T-plate 409 is placed on the top of the pulley seat 408, a guide plate 410 is slidably connected to the outer side of the middle part of the T-plate 409, and a connecting ear 411 is slidably connected to one end of the T-plate 409, and a sealing plate 412 is fixed to the side of the connecting ear 411, the guide plate 410 is fixedly connected to the kiln body 2, and the sealing plate 412 is rotatably connected to the kiln body 2, and the sealing plates 412 are equidistantly distributed along the inner circumference of the kiln body 2;

[0028] The specific operation is as follows: the sampling device is integrated into multiple positions on the rotary kiln. When sampling and analysis are required during the lithium ore production process, it is only necessary to rotate the worm 401 at the designated position to drive the crankshaft 403 to rotate through the worm gear 402, and rotate the cam ring 404 to the bottom of the limit plate 405. At this time, the limit plate 405 will move downward under the action of gravity, and the blockage of the pulley seat 408 will be released. The T-shaped plate 409 will not support the sealing plate 412, so that when the sealing plate 412 is located at the upper part of the sampling box 3, it will automatically rotate to the open state, so that part of the material there can fall into the sampling box 3, and in the process of the limit plate 405 moving downward, it will also pull the connecting plate 407 so that it is in the limit plate The end of 405 slides inward to connect the limit plate 405 with the fixed sleeve 1. Therefore, when the kiln body 2 drives the T-plate 409 to move synchronously through the guide plate 410 during rotation, the inclined connecting plate 407 is used to ensure that the pulley seat 408 can slide to the inside of the fixed sleeve 1, so that the sealing plate 412 is automatically closed to prevent heat leakage. After sampling, the worm 401 is rotated again. Similarly, the convex part of the cam ring 404 can squeeze the bottom of the limit plate 405 to move it upward, and the T-plate 409 will push the sealing plate 412 through the connecting ear 411 to close the kiln body 2. After closing, its inner side will be flush with the inside of the kiln body 2 to avoid material accumulation, which is conducive to maintaining the normal and stable operation of the kiln body 2.

[0029] See also Figure 1 、 Figures 4 to 6 , a pointer 5 is fixed to one end of the crankshaft 403, and an identification plate 6 is slidably connected to one side of the pointer 5, the identification plate 6 is rotatably connected to the worm 401, and the identification plate 6 is fixedly connected to the sampling box 3, the middle of the crankshaft 403 is connected to a linkage assembly 7, and the linkage assembly 7 includes a connecting rod 701, the middle of the crankshaft 403 is rotatably connected to the connecting rod 701, and the end of the connecting rod 701 is rotatably connected to the driving column 702, the end of the driving column 702 is fixedly connected to the discharge plate 703, and the discharge plate 703 is slidably connected to the sampling box 3, the other end of the crankshaft 403 A fixed column 704 is arranged, and a lifting slot plate 705 is slidably connected to the outer side of the fixed column 704, and a transmission rod 706 is internally rotatably connected to one end of the lifting slot plate 705, and a bracket 707 is slidably connected to the middle part of the transmission rod 706, and the bracket 707 is fixedly connected to the sampling box 3, and a gear shaft 708 is internally rotatably connected to one end of the bracket 707, and a gear ring 709 is meshed with the top of the gear shaft 708, and the gear ring 709 is fixedly connected to the kiln body 2, and a rubber plate 710 is fixed to the lower end of the gear shaft 708 and the top of the transmission rod 706;

[0030] The specific operation is as follows: when the cam ring 404 rotates counterclockwise to open the upper sealing plate 412, the crankshaft 403 will rotate counterclockwise to cause the connecting rod 701 to push the driving column 702, thereby driving the discharge plate 703 to slide inside the sampling box 3, so that the interior of the sampling box 3 is closed. Therefore, during the sampling process, the overall sealing can be maintained, reducing the heat leakage in the kiln body 2, which is conducive to maintaining the stability of the temperature inside the kiln body 2. During this process, the fixed column 704 will rotate to the bottom, so that there is no transmission between the gear shaft 708 and the transmission rod 706. After sampling, when the worm gear 402 continues to rotate to close the sealing plate 412, the driving column 702 will be pulled by the connecting rod 701, so that the discharge plate 703 is opened. This will discharge the material accumulated inside so that subsequent cooling operations can be carried out. At the same time, the fixed column 704 will also rotate upward, thereby driving the lifting slot plate 705 to move upward along the outer side of the lower end column of the bracket 707, so that the transmission rod 706 and the rubber plate 710 at the end of the gear shaft 708 are tightly fitted, so as to utilize friction for transmission. Therefore, during the rotation of the kiln body 2, it will also automatically drive the lower cooling mechanism to work, and after sampling, the worm 401 can also be rotated to lower the height of the fixed column 704, so that the transmission operation can be disconnected when not in use to reduce load energy consumption, and the crankshaft 403 will also drive the pointer 5 to slide on the identification plate 6 when rotating, so that the control status at this time can be easily observed through the identification plate 6.

[0031] See also Figure 1 、 Figures 5 to 7 , a cooling component 8 is provided at the bottom of the sampling box 3, and the bottom of the cooling component 8 is connected to the collecting box 9, the cooling component 8 includes a cooling box 801, a cooling box 801 is placed at the bottom of the sampling box 3, and a wind cover 802 is provided on one side of the cooling box 801, the middle part of the wind cover 802 is rotatably connected to a transmission sleeve 803, and the transmission sleeve 803 is slidably connected to the transmission rod 706, and a fan blade 804 is provided at the lower end of the transmission sleeve 803, a bevel gear set 805 is provided on the outer side of the middle part of the transmission sleeve 803, and one end of the bevel gear set 805 is connected to a camshaft 806, the camshaft 806 is rotatably connected to the sampling box 3, and the cam A ball-head rubber rod 807 is fixed to the outer peripheral surface of the middle portion of the wheel shaft 806, and roller seats 808 are connected to both ends of the bottom of the camshaft 806, and a guide frame 809 is placed at the bottom of the roller seat 808, and a spring seat 810 is connected to the bottom of the roller seat 808, and the spring seat 810 is fixedly connected to the cooling box 801, and a diverter plate 811 is placed on one side of the cooling box 801, and the diverter plate 811 is fixedly connected to the wind cover 802, and the diverter plate 811 is connected to the interior of the wind cover 802 through a pipe, and filter plates 812 are placed inside the two sides of the cooling box 801, and the other side of the cooling box 801 is connected to the air collecting cover 813;

[0032] The specific operation is as follows: when the transmission rod 706 rotates, it will also drive the transmission sleeve 803 to rotate, which can drive the camshaft 806 to rotate through the bevel gear set 805, so that the flexible ball head rubber rod 807 knocks on the bottom of the sampling box 3, reducing the material residue on the discharge plate 703, and then the material will fall onto the guide frame 809 and gradually fall along the inclined partition inside the guide frame 809, which is conducive to prolonging the time that the sample material stays inside the cooling box 801. During this process, the transmission sleeve 803 will drive the fan blade 804 to rotate, so that the airflow inside the wind hood 802 is evenly blown into the cooling box under the diversion of the diversion orifice plate 811. 801 and is discharged from the air collecting hood 813 through the filter plate 812 so that the heat and exhaust gas after heat exchange can be collected and processed later. The spring seat 810 will push the guide frame 809 so that the roller seat 808 is always in contact with the camshaft 806. Therefore, during the rotation of the camshaft 806, the guide frame 809 can vibrate up and down, so that the internal material can fall normally, and the material can also be dispersed, thereby improving the effect of heat exchange and cooling. The material after cooling will fall into the collection box 9. Therefore, the sample material will be automatically cooled during the sampling process, which is convenient for the normal progress of subsequent detection tests.

[0033] In summary, when using the sampling device for lithium ore rotary kiln detection, first when sampling at a designated location of the rotary kiln, the worm 401 at the designated location is rotated first, so that it drives the crankshaft 403 to rotate through the worm gear 402, and the cam ring 404 is rotated counterclockwise to the bottom of the limit plate 405. At this time, the limit plate 405 will move downward under the action of gravity, and the obstruction of the pulley seat 408 will be released. The T-shaped plate 409 will not support the sealing plate 412, so that when the sealing plate 412 is located at the upper part of the sampling box 3, it will automatically rotate to the open state, so that part of the material at this location can fall into the sampling box 3, and the crankshaft 403 will also drive the pointer 5 to slide on the identification plate 6 when rotating, so that the control status at this time can be easily observed through the identification plate 6.

[0034] Secondly, the crankshaft 403 rotates counterclockwise, causing the connecting rod 701 to push the driving column 702, thereby driving the discharge plate 703 to slide inside the sampling box 3, making the interior of the sampling box 3 closed. Therefore, during the sampling process, the entire box can be kept airtight, reducing the heat leakage from the kiln body 2. During this process, the fixed column 704 rotates to the bottom, so that the transmission between the gear shaft 708 and the transmission rod 706 is not carried out.

[0035] Next, as the limiting plate 405 moves downward, the connecting plate 407 is pulled to slide inside the end of the limiting plate 405 to connect the limiting plate 405 with the fixed sleeve 1. Therefore, when the kiln body 2 rotates, the guide plate 410 drives the T-shaped plate 409 to move synchronously. The inclined connecting plate 407 ensures that the pulley seat 408 can slide to the inside of the fixed sleeve 1, so that the sealing plate 412 is automatically closed.

[0036] Then, after sampling, the worm 401 is rotated again, and similarly, the convex part of the cam ring 404 can squeeze the bottom of the limit plate 405 to move it upward, and the T-plate 409 will push the sealing plate 412 through the connecting ear 411 to close the kiln body 2. After closing, its inner side will be flush with the inside of the kiln body 2 to avoid material accumulation. At the same time, the connecting rod 701 will pull the driving column 702 to open the discharge plate 703, so that the material accumulated inside can be discharged. In this process, the fixed column 704 will also rotate upward, thereby driving the lifting trough plate 7 05 moves upward along the outer side of the lower end column of the bracket 707, so that the transmission rod 706 and the rubber plate 710 at the end of the gear shaft 708 fit tightly together, so as to utilize friction for transmission. Therefore, during the rotation of the kiln body 2, the transmission rod 706 will be driven to rotate through the gear ring 709, the gear shaft 708, and the rubber plate 710, so that the transmission sleeve 803 rotates, thereby driving the cam shaft 806 to rotate through the bevel gear set 805, so that the flexible ball head rubber rod 807 knocks on the bottom of the sampling box 3, reducing the material residue on the discharge plate 703;

[0037] Finally, the material will fall onto the guide frame 809 and gradually fall along the inclined partition inside the guide frame 809. During this process, the transmission sleeve 803 will drive the fan blade 804 to rotate, so that the air flow inside the wind hood 802 is evenly blown into the interior of the cooling box 801 under the diversion of the diversion orifice plate 811, and discharged from the air collecting hood 813 through the filter plate 812, so that the heat and exhaust gas after heat exchange can be collected and processed subsequently. The spring seat 810 will push the guide frame 809 so that the roller seat 808 is always in contact with the camshaft 806. Therefore, during the rotation of the camshaft 806, the guide frame 809 can vibrate up and down, so that the internal material can fall normally, and the cooled material will fall into the collection box 9. Therefore, during the sampling process, the sample material will be automatically cooled, which is convenient for the normal progress of subsequent detection tests. After sampling, the worm 401 can also be rotated to lower the height of the fixed column 704, so that the transmission operation can be disconnected when not in use to reduce load energy consumption.
