[0036] Such as Figures 1 - 10As shown, a molten salt melting granulation device and a granulation method include a tank body 1 and a feed pipe 101 arranged on the outer peripheral wall of the tank body 1 and communicated with the tank body 1. The tank body 1 can be heated by means such as resistance heating or induction heating. Of course, these heating methods are all mature technical means, and the specific structure and working principle of heating will not be elaborated here. A cooling tower 4 is arranged on one side of the tank body 1. A pump body 3 is arranged between the tank body 1 and the cooling tower 4. Through the arranged pump body 3, the raw materials in the tank body 1 can be introduced into the cooling tower 4. The raw materials are sprayed out from the top of the cooling tower 4 and are cooled to form particulate matter. The cooling tower 4 is a commonly used device in molten salt granulation. Here, the specific structure and working principle of the cooling tower 4 will not be elaborated.

[0037] A discharge pipe is communicated and arranged at a position on the outer peripheral wall of the tank body 1 close to the bottom end, and the discharge pipe is connected to the input end of the pump body 3. A diversion pipe is communicated and arranged between the output end of the pump body 3 and the top end of the cooling tower 4. Through this structure, the raw materials can be transported into the cooling tower 4;

[0038] In order to better mix various raw materials, a rotating shaft 5 is rotatably installed in the tank body 1 in this solution. The rotating shaft 5 is coaxially arranged with the tank body 1, and a stirring rod 8 is installed on the outer peripheral wall of the rotating shaft 5. Although the arranged stirring rod 8 can accelerate the mixing of various raw materials, to a certain extent, it will also affect the stability of the pump body 3 in extracting liquid, thereby affecting the stability of the raw materials being exported at one end of the cooling tower 4. Based on the above problems, a plurality of annular grooves are opened on the outer peripheral wall of the rotating shaft 5 in this solution. The plurality of annular grooves are evenly distributed along the axial direction of the rotating shaft 5, and a clamping ring 11 is rotatably installed at the annular grooves. Specifically, the outer wall of the clamping ring 11 is aligned with the outer peripheral surface of the rotating shaft 5, and the above-mentioned stirring rod 8 is fixedly arranged on the outer side surface of the clamping ring 11;

[0039] Combined with Figures 5 - 9As shown, the shaft 5 can only rotate in a single direction relative to the snap ring 11. In addition, the snap ring 11 is provided with a clamping assembly that cooperates with the shaft 5. A cover plate 6 is provided inside the tank body 1, and a baffle 7 is rotatably connected to the lower side of the cover plate 6. The baffle 7 and the cover plate 6 are elastically matched. The cover plate 6 and the baffle 7 are both sleeved on the outside of the shaft 5 and can rotate and move relative to the shaft 5. A through slot 602 is provided on the cover plate 6, and a through slot 700 that cooperates with the through slot 602 is provided on the baffle 7. 5. In actual use, when the through slot 602 on the cover plate 6 is staggered with the through slot 705 on the baffle 7, the cover plate 6 and the baffle 7 can cooperate to divide the tank body 1 into two parts, and when the through slot 602 is aligned with the through slot 705, the stirring rod 8 on the outside of the rotating shaft 5 can pass through the cover plate 6 and the baffle 7. In the specific use process, when the rotating shaft 5 rotates in the forward direction, the stirring rod 8 can be driven to rotate by the rotating shaft 5, thereby stirring the raw materials in the tank body 1, which is conducive to accelerating the mixing of the raw materials. After the material mixing is completed, the raw materials can be extracted into the cooling tower 4 through the pump body 3. At this time, the rotating shaft 5 can rotate in the opposite direction. In this state, the rotating shaft 5 does not drive the stirring rod 8 to rotate. During the reverse rotation of the rotating shaft 5, the cover plate 6 and the baffle 7 are moved downward relative to the tank body 1. When the baffle 7 moves downward to a state where it is in contact with the top of the stirring rod 8, the stirring rod 8 can be matched with the rotating shaft 5 through the clamping assembly, so that during the reverse rotation of the rotating shaft 5, the stirring rod 8 can be driven to rotate synchronously through the clamping assembly, thereby stirring the raw materials above the cover plate 6. The purpose of this arrangement is that: during the process of the pump body 3 extracting the raw materials, raw materials can be added to the tank body 1 at the same time, which is conducive to making full use of the heat in the tank body 1. The baffle 7 cooperates with the cover plate 6 to prevent the raw materials above the cover plate 6 from falling. On the other hand, through the clamping assembly, only the stirring rod 8 located above the cover plate 6 can rotate in the opposite direction with the rotating shaft 5, which can avoid stirring the solution below the baffle 7.

[0040] like Figures 2 - 15 As shown, the above-mentioned clamping assembly includes a clamping block 1101 provided on the inner wall of the clamping ring 11 and elastically connected to the clamping ring 11, and a plurality of clamping grooves 501 cooperating with the clamping block 1101 are opened on the peripheral wall of the inner cavity of the annular groove. When the clamping block 1101 is in the pop-up state and inserted into the clamping groove 501, the clamping ring 11 can be driven to rotate synchronously during the rotation of the rotating shaft 5. A pressure rod 801 is elastically installed on the top surface of the stirring rod 8. A second pull rope 12 is fixedly provided between the pressure rod 801 and the clamping block 1101. The second pull rope 12 passes through the stirring rod 8 and slides with it.

[0041] Further, combined with Figure 10As shown, positioning blocks 10 are arranged on both sides of the pressing rod 801 on the stirring rod 8, and the positioning blocks 10 are elastically connected to the stirring rod 8. Sliders 802 are slidably arranged on both side surfaces of the stirring rod 8. A notch 8021 is formed on the outer side surface of the slider 802. A first pulling rope 9 is fixedly arranged between the slider 802 and the positioning block 10. The first pulling rope 9 passes through the stirring rod 8 and is slidably matched with it. Positioning holes 8011 matching the positioning blocks 10 are formed on both side surfaces of the pressing rod 801. Combining Figures 2 - 5 As shown, pushing blocks 701 elastically matched with the sliders 802 are arranged on both inner side surfaces of the through groove 705. One end of the pushing block 701 close to the through groove 705 is of an arc surface structure. Specifically, when the baffle 7 moves upward relative to the stirring rod 8 and the pushing block 701 is aligned with the notch 8021, the pushing block 701 can drive the slider 802 to move upward, so as to pull the positioning block 10 by the first pulling rope 9, so that the positioning block 10 is separated from the positioning hole 8011, and the pressing rod 801 can bounce upward.

[0042] During actual use, the raw materials are introduced into the tank body 1 through the feed pipe 101 for heating. The stirring rod 8 is driven to rotate synchronously by the forward rotation of the rotating shaft 5. The stirring rod 8 can be used to accelerate the mixing of the raw materials. The raw materials can be pumped to the cooling tower 4 by the pump body 3 and exported. The exported raw materials are cooled and transformed into granular form. During the process of the pump body 3 pumping the raw materials into the cooling tower 4, the rotating shaft 5 is driven to rotate reversely. In this state, the rotating shaft 5 cannot drive the stirring rod 8 to rotate, so that the liquid raw materials in the tank body 1 can be kept stable, and the liquid raw materials pumped to the cooling tower 4 by the pump body 3 and exported can be more stable;

[0043] As the liquid raw material is continuously extracted, the liquid level in the tank body 1 gradually decreases. At this time, the raw material is replenished into the tank body 1 through the feeding pipe 101 and the cover plate 6 and the baffle 7 are driven to move downward relative to the tank body 1. When the baffle 7 moves downward and fits the stirring rod 8, the baffle 7 can squeeze the pressure rod 801 so that the pressure rod 801 moves downward relative to the stirring rod 8. During this process, the second pull rope 12 connected to the pressure rod 801 will be in a loosened state, so that the card block 1101 can pop out. When the card block 1101 is aligned with the card slot 501 and inserted into the card slot 501, the rotating shaft 5 can synchronously drive the stirring rod 8 to rotate during the reverse rotation. The stirring rod 8 rotating in the reverse direction can be used to mix the raw materials above the cover plate 6. When the rotating shaft 5 drives the stirring rod 8 to rotate in the reverse direction and aligns with the through groove 705 on the baffle 7, the baffle 7 can move downward relative to the stirring rod 8. , so that the stirring rod 8 is inserted into the through groove 705 and the top surface of the stirring rod 8 is in contact with the bottom surface of the cover plate 6. At this time, the stirring rod 8 can drive the baffle 7 to rotate together. Since the raw materials are piled up above the cover plate 6, the cover plate 6 is subjected to a large resistance, so that the baffle 7 can rotate relative to the cover plate 6. When the through groove 705 on the baffle 7 is aligned with the through groove 602 on the cover plate 6, the cover plate 6 can move downward relative to the stirring rod 8. Specifically, when the stirring rod 8 is completely removed from the through groove 705, the baffle 7 will rotate relative to the cover plate 6 and reset, so that the through groove 705 and the through groove 602 are staggered, which can prevent the material on the cover plate 6 from falling to the bottom end of the tank body 1. At this point, the baffle 7 and the cover plate 6 move downward and pass the stirring rod 8, and the stirring rod 8 can rotate in the opposite direction with the rotating shaft 5 through the cooperation of the card block 1101 and the card slot 501, thereby mixing the raw materials on the cover plate 6.

[0044] To sum up, this device can add raw materials to the tank body 1 during the process of the pump body 3 extracting liquid raw materials, which is beneficial to fully utilize the heat in the tank body 1, and when the cover plate 6 and the baffle 7 pass through the stirring rod 8, the stirring rod 8 can rotate in the opposite direction with the rotating shaft 5, thereby mixing the raw materials on the cover plate 6, while the stirring rod 8 under the cover plate 6 cannot rotate synchronously with the rotating shaft 5, which is beneficial to maintaining the stability of the liquid raw materials in the tank body 1, so that the pump body 3 can extract the liquid raw materials more stably.

[0045] Combine Figures 9 - 13 As shown, the baffle 7 is elastically connected to the insertion rod 15, and the insertion rod 15 can move in the vertical direction relative to the baffle 7. The cover plate 6 is provided with a slot 606 that matches the insertion rod 15. When the through slot 705 is aligned with the through slot 602, the insertion rod 15 and the slot 606 are in a collinear state.

[0046] Furthermore, the whole of the inserting rod 15 is arranged in a cross shape, and a cross groove for sliding cooperation with the inserting rod 15 is formed in the baffle 7. Elastic bump 1501 is connected to both end faces of the inserting rod 15, and a groove 704 matching with the bump 1501 is formed in the inner wall of the cross groove. One end of the bump 1501 away from the inserting rod 15 is of an arc surface structure. Specifically, when the acting force between the bump 1501 and the groove 704 is relatively large, the bump 1501 can move out of the groove 704. During use, when the baffle 7 falls near the bottom end of the tank body 1, one of the stirring rods 8 at the bottommost position on the rotating shaft 5 will be inserted between the baffle 7 and the cover plate 6, so as to keep the cover plate 6 and the baffle 7 relatively stable, and the inserting rod 15 is also aligned with the slot 606 on the cover plate 6. Therefore, when the baffle 7 moves near the bottom end of the tank body 1 and the inserting rod 15 contacts the bottom surface of the tank body 1, the inserting rod 15 can be jacked up and inserted into the slot 606 to lock the baffle 7 and the cover plate 6, avoiding relative rotation between the baffle 7 and the cover plate 6. When the bump 1501 is aligned with the groove 704, the bump 1501 will be inserted into the groove 704 to keep the inserting rod 15 stable. Subsequently, when driving the baffle 7 and the cover plate 6 to move upward, the baffle 7 and the cover plate 6 can sequentially pass through a plurality of stirring rods 8 in the vertical direction until the cover plate 6 moves near the top end of the tank body 1. The top end of the inserting rod 15 is pressed to move downward. During this process, the bump 1501 is compressed and retracted into the inserting rod 15, and the inserting rod 15 then drops accordingly. In summary, through the arranged inserting rod 15 in this solution, when the cover plate 6 and the baffle 7 fall near the bottom end of the tank body 1, the bottommost stirring rod 8 will be inserted between the baffle 7 and the cover plate 6, and the inserting rod 15 can lock the baffle 7 and the cover plate 6, thus avoiding relative rotation between the two, which is beneficial to the reset of the baffle 7 and the cover plate 6.

[0047] Combined with Figures 1 - 9 As shown, in order to drive the movement of the baffle 7 and the cover plate 6, a towing rope 2 is arranged at the top end position of the tank body 1. A pull ring 601 is rotatably connected to the top surface of the cover plate 6. Referring to Figure 13 As shown, an installation groove matching with the pull ring 601 is formed in the cover plate 6. The cross sections of the installation groove and the pull ring 601 are both arranged in a T shape, so that the pull ring 601 can be stably placed in the installation groove and move relative to the cover plate 6. A winding motor is installed at the top end position of the tank body 1. One end of the towing rope 2 is connected to the pull ring 601, and the other end of the towing rope 2 is fixedly connected to a reel connected to the winding motor. By the forward and reverse operation of the winding motor, the towing rope 2 can be wound or unwound, so as to drive the baffle 7 and the cover plate 6 to move in the vertical direction.

[0048] A pulley that mates with the towing rope 2 is installed on the tank body 1. A end cover is fixedly installed at the top of the tank body 1, and the towing rope 2 passes through the end cover and is in sliding fit with it. The rotating shaft 5 is in rotational fit with the tank body 1, and the top end of the rotating shaft 5 passes through the end cover and is in rotational fit with the end cover. A motor is installed on the end cover, and there is a transmission connection between the output shaft of the motor and the rotating shaft 5. Specifically, structures such as a chain or a gear can be used to make the motor drive the rotating shaft 5 to rotate forward or backward.

[0049] Through holes for the rotating shaft 5 to pass through are provided on both the cover plate 6 and the baffle 7, and the above-mentioned through slot 705 and through groove 602 are both communicated with the through hole.

[0050] Refer to Figures 1 - 5 As shown, a chute that slidably mates with the slider 802 is provided on the outer side surface of the stirring rod 8. In the initial state, the slider 802 is located at the bottom end position of the chute. This results in that the slider 802 will not be driven to move when the baffle 7 moves downward relative to the stirring rod 8, and when the baffle 7 moves upward relative to the stirring rod 8, the slider 802 can be driven to move upward through the push block 701.

[0051] Combined with Figures 6 - 8 As shown, a stepped hole for installing the cover plate 6 is provided on the top end face of the baffle 7. A fixing block 702 is fixedly provided at the bottom of the stepped hole and near the edge. An arc-shaped clamping portion 603 is integrally formed at a position near the bottom end of the outer circumferential surface of the cover plate 6. The clamping portion 603 rotates in the stepped hole. A stop block 604 is fixedly provided at a position near the bottom end of the outer circumferential surface of the cover plate 6. The stop block 604 is located inside the stepped hole and near the edge, and a limiting spring 703 is fixedly provided between the stop block 604 and the fixing block 702 to achieve the elastic fit between the baffle 7 and the cover plate 6.

[0052] A convex ring portion 605 is integrally formed at a position near the top end of the outer circumferential surface of the cover plate 6. The convex ring portion 605 covers the top surface of the baffle 7. The outer circumferential surfaces of both the baffle 7 and the convex ring portion 605 are in contact with the inner wall of the tank body 1.

[0053] A connecting groove that slidably mates with the pressure rod 801 is provided on the stirring rod 8. A support spring is fixedly provided between the inner end face of the connecting groove and the pressure rod 801. An installation hole that slidably mates with the positioning block 10 is provided on the inner wall of the connecting groove. A first spring is fixedly provided between the inner end face of the installation hole and the positioning block 10.

[0054] A circular hole that slidably mates with the clamping block 1101 is provided on the inner wall of the snap ring 11. An extrusion spring is fixedly provided between the inner end face of the circular hole and the clamping block 1101.

[0055] In order to achieve one-way cooperation between the rotating shaft 5 and the snap ring 11, it can be realized by installing a one-way bearing between the snap ring 11 and the rotating shaft 5. Here, another embodiment is given. Specifically, a strip-shaped groove can be opened on the inner wall of the annular groove, and a limiting block 502 is slidably arranged in the strip-shaped groove. A spring is fixedly arranged between the limiting block 502 and the inner end face of the strip-shaped groove, and one end of the limiting block 502 close to the snap ring 11 is set as an inclined extrusion surface 5021. A plurality of limiting grooves matching with the limiting block 502 are opened on the inner wall of the snap ring 11. Through this structure, one-way cooperation between the snap ring 11 and the rotating shaft 5 can also be achieved.

[0056] Combined with Figure 13 As shown, receiving grooves slidably matched with the convex blocks 1501 are opened at the left and right end faces of the insertion rod 15, and a second spring is fixedly arranged between the inner end face of the receiving groove and the convex blocks 1501.

[0057] In the above description, one end of the towing rope 2 far from the winding motor is connected to the pull ring 601. Specifically, a pull rod 13 can be fixedly arranged on the top surface of the pull ring 601. A sleeve 14 is slidably sleeved on the outer side of the pull rod 13. The cross section of the pull ring 601 is T-shaped, and a third spring is fixedly arranged between the part of the pull rod 13 close to the top end and the inner bottom surface of the sleeve 14. One end of the above-mentioned towing rope 2 can be fixedly connected to the sleeve 14. Through this mechanism, it can be avoided that there is a large pressure between the baffle 7 or the cover plate 6 and the stirring rod 8. During specific use, balls can be installed on both the top surface and the bottom surface of the stirring rod 8 to reduce the friction between the stirring rod 8 and the baffle 7 and the cover plate 6.
