[0003] Patent CN117643962A discloses a fluorite ore sorting device and its usage method for gravity separation and purification of high-quality fluorite ore. Specifically, the patent discloses "a fluorite ore sorting device for gravity separation and purification of high-quality fluorite ore, relating to the field of fluorite ore sorting technology, including a support frame, a sorting mechanism fixedly connected to the top of the support frame, and a gravity partitioning mechanism fixedly connected to the top of the sorting mechanism; the gravity partitioning mechanism includes an impact trough, and a water inlet trough is connected to the side wall of the impact trough." This invention achieves the technical effect that "by setting multiple sets of screens to perform gravity separation simultaneously, the sorting efficiency can be maximized while ensuring the sorting effect during the gravity separation process. Furthermore, before the ore enters the screens, the ore is preliminarily classified by the dynamic partitioning mechanism, thus better separating the fluorite ore during the gravity separation process. During the gravity separation process, the impurities discharged from the previous set of screens enter the next set of screens for further sorting, thereby preventing residual fluorite ore inside the impurities."

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. On the one hand, the internal rotating connection of the sorting ring is a thermal effect roller, and there is a gap between the thermal effect roller and the inner wall of the sorting ring. Several sieve plates are fixedly installed inside the sorting ring, and the mesh counts of the sieve plates are not equal. On the other hand, the output end of the hot box is equipped with a pipe connected to the thermal effect roller, and a valve is installed on one side of the pipe. The outer wall of the thermal effect roller is made of deformation layer thermosensitive shape memory alloy, and the liquid chamber changes the size of the gap between the thermal effect roller and the sorting ring by the temperature input from the hot box. Therefore, hot water of different temperatures can be input into the thermal effect roller through the hot box to deform the thermal effect roller, thereby changing the size of the gap between different thermal effect rollers and the sorting ring. Then, the crystals prepared by N-ethylcarbazole can be ground according to the size requirements. Not only can the sieve plates achieve grading and screening, but the thermal effect rollers can also achieve the required grading and processing of the crystals prepared by N-ethylcarbazole.

[0022] 2. Since the rapping head includes a telescopic rod, a spring, and a ball head, one end of the telescopic rod is fixedly connected to the rapping roller, and the other end of the telescopic rod is fixedly connected to the ball head. The telescopic rod is equipped with a spring inside that can control its movement. Therefore, the centrifugal force generated by the rotation of the rapping roller can cause the telescopic rod to shift, thereby causing the ball head to strike the ring. This prevents excessive adhesion of N-ethylcarbazole crystals to the surface of the ring and avoids affecting the screening of N-ethylcarbazole crystals. At the same time, the spring can cause the telescopic rod to retract, thus ensuring the rapping head's striking effect on the ring. Attached Figure Description

On the other hand, the output end of the hot box 31 is provided with a pipe connected to the thermal effect roller 4, and a valve is installed on one side of the pipe. The outer wall of the thermal effect roller 4 is made of a deformation layer 43 made of thermosensitive shape memory alloy. The liquid chamber 41 changes the size of the gap between the thermal effect roller 4 and the sorting ring 1 through the temperature input from the hot box 31. Therefore, hot water of different temperatures can be input into the thermal effect roller 4 through the hot box 31 to deform the thermal effect roller 4, thereby changing the size of the gap between the different thermal effect rollers 4 and the sorting ring 1. Then, the crystals prepared by N-ethylcarbazole are ground according to the size requirements. Not only can the sieve plate 12 be used to achieve grading and screening, but the thermal effect roller 4 can also be used to perform grading and processing of the crystals prepared by N-ethylcarbazole according to the requirements.

[0035] Step S1: Drive the active gear 51 to rotate and cause the active gear 51 to drive the driven gear 52 to rotate, and the driven gear 52 to drive each liquid collection chamber 41 to rotate in the sorting chamber 13;

[0036] Step S2: By introducing liquids of different temperatures into the liquid-polymerizing chamber 41 through their respective branch pipes 34, the size of the gap between the liquid-polymerizing chamber 41 and the ring body 11 is changed to match the size requirements for preparing N-ethylcarbazole crystals.

[0037] Step S3: The crystals prepared by N-ethylcarbazole are crushed after being squeezed by the gap. The degree of compression is affected by the liquid temperature input by the thermal effect component 3. The higher the temperature, the greater the expansion of the thermal effect roller 4, and the smaller the crystals that are crushed and ground, and vice versa.

[0038] Step S4: Screen and collect N-ethylcarbazole crystals of different sizes through sieve plate 12 to complete the collection.

The telescopic rod 721 is equipped with a spring 722 that can control the movement of the telescopic rod 721. Therefore, the centrifugal force generated by the rotation of the rapping roller 71 can cause the telescopic rod 721 to shift, thereby causing the ball head 723 to strike the ring 11. This avoids excessive adhesion of N-ethylcarbazole crystals to the surface of the ring 11 and affects the screening of N-ethylcarbazole crystals. At the same time, the spring 722 can cause the telescopic rod 721 to retract, thereby ensuring the striking effect of the rapping head 72 on the ring 11.

The liquid chamber 41 changes the size of the gap between the thermal effect roller 4 and the sorting ring 1 through the temperature input from the hot box 31. Therefore, hot water of different temperatures can be input into the thermal effect roller 4 through the hot box 31 to deform the thermal effect roller 4, thereby changing the size of the gap between the different thermal effect rollers 4 and the sorting ring 1. Then, the crystals prepared by N-ethylcarbazole are ground according to the size requirements. Not only can the sieve plate 12 be used to achieve grading and screening, but the thermal effect roller 4 can also be used to perform grading and processing of the crystals prepared by N-ethylcarbazole according to the requirements.

The telescopic rod 721 is equipped with a spring 722 that can control the movement of the telescopic rod 721. Therefore, the centrifugal force generated by the rotation of the rapping roller 71 can cause the telescopic rod 721 to shift, thereby causing the ball head 723 to strike the ring 11. This avoids excessive adhesion of N-ethylcarbazole crystals to the surface of the ring 11 and affects the screening of N-ethylcarbazole crystals. At the same time, the spring 722 can cause the telescopic rod 721 to retract, thereby ensuring the striking effect of the rapping head 72 on the ring 11.
