DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10 As shown, a molten salt melt 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 connected to the tank body 1. The tank body 1 can be heated by resistance heating or induction heating. Of course, these heating methods are mature technical means. The specific structure and working principle of the heating are not described in detail here. A cooling tower 4 is arranged on one side of the tank body 1, and a pump body 3 is arranged between the tank body 1 and the cooling tower 4. The raw material in the tank body 1 can be introduced into the cooling tower 4 through the arranged pump body 3. The raw material is sprayed out from the top of the cooling tower 4 and is cooled to form particles. The cooling tower 4 is a commonly used equipment in molten salt granulation. Here, the specific structure and working principle of the cooling tower 4 are not described in detail.

[0021] A discharge pipe is provided on the outer peripheral wall of the tank body 1 near the bottom, and the discharge pipe is connected to the input end of the pump body 3. A guide pipe is provided between the output end of the pump body 3 and the top of the cooling tower 4. Through this structure, the raw materials can be transported to the cooling tower 4. In order to better mix the various raw materials, the present invention has a rotating shaft 5 rotatably installed in the tank body 1, the rotating shaft 5 is coaxially arranged with the tank body 1, and a stirring rod 8 is installed at the outer peripheral wall of the rotating shaft 5. Although the stirring rod 8 can accelerate the mixing of the raw materials, it will also affect the stability of the pump body 3 extracting the liquid to a certain extent, thereby affecting the stability of the raw materials being discharged at one end of the cooling tower 4. Based on the above problems, the present invention has a plurality of annular grooves on the outer peripheral wall of the rotating shaft 5, and 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 groove. 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 at the outer side surface of the clamping ring 11; Combination Figure 5-Figure 9 As shown, the rotating 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 matches the rotating shaft 5. The tank body 1 is provided with a cover plate 6, and a baffle plate 7 is rotatably connected below the cover plate 6. The baffle plate 7 is elastically matched with the cover plate 6. The cover plate 6 and the baffle plate 7 are both sleeved on the outside of the rotating shaft 5 and can rotate and move relative to the rotating shaft 5. A through groove 602 is provided on the cover plate 6, and a through groove 70 matching the through groove 602 is provided on the baffle plate 7. 5. In actual use, when the through groove 602 on the cover plate 6 and the through groove 705 on the baffle plate 7 are staggered, the cover plate 6 and the baffle plate 7 can cooperate to divide the tank body 1 into two parts, and when the through groove 602 and the through groove 705 are aligned, the stirring rod 8 on the outside of the rotating shaft 5 can pass through the cover plate 6 and the baffle plate 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, so as to stir 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 material 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 material above the cover plate 6. The purpose of this arrangement is that during the process of the pump body 3 extracting the raw material, the raw material 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. By cooperating with the cover plate 6, the raw material above the cover plate 6 can be prevented 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, thereby avoiding stirring the solution below the baffle 7.

[0022] like Figure 2-Figure 15As shown, the above-mentioned clamping assembly includes a clamping block 1101 arranged 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 a 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, and a second pull rope 12 is fixedly arranged between the pressure rod 801 and the clamping block 1101, and the second pull rope 12 passes through the stirring rod 8 and slidably cooperates with it; Furthermore, combined with Fig.10 As shown, the stirring rod 8 is provided with positioning blocks 10 on both sides of the pressure rod 801, and the positioning blocks 10 are elastically connected to the stirring rod 8. Slide blocks 802 are slidably provided on both sides of the stirring rod 8. A notch 8021 is provided on the outer side of the slide block 802. A first pull rope 9 is fixedly provided between the slide block 802 and the positioning block 10. The first pull rope 9 passes through the stirring rod 8 and slidably cooperates with the stirring rod 8. Positioning holes 8011 cooperating with the positioning blocks 10 are provided on both sides of the pressure rod 801. Figure 2-Figure 5 As shown, push blocks 701 cooperating with the slider 802 are elastically provided on both side surfaces inside the through groove 705, and one end of the push block 701 close to the through groove 705 is set as a curved surface structure. Specifically, when the baffle 7 moves upward relative to the stirring rod 8 and the push block 701 is aligned with the notch 8021, the slider 802 can be driven to move upward by the push block 701, so that the positioning block 10 is pulled out of the positioning hole 8011 by the first pull rope 9, so that the pressure rod 801 can bounce upward.

[0023] In actual use, the raw material is introduced into the tank body 1 through the feed pipe 101 for heating, and the stirring rod 8 is driven to rotate synchronously by the positive rotation of the rotating shaft 5. The stirring rod 8 can accelerate the mixing of the raw materials, and the raw materials can be extracted to the cooling tower 4 through the pump body 3 for export. The exported raw materials are cooled and converted into granular form. In the process of the pump body 3 extracting the raw materials and sending them to the cooling tower 4, the rotating shaft 5 is driven to rotate in the opposite direction. In this state, the rotating shaft 5 cannot drive the stirring rod 8 to rotate, so that the liquid raw material in the tank body 1 can remain stable, so that the liquid raw material extracted by the pump body 3 to the cooling tower 4 and exported can be more stable; 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 feed pipe 101 and drives the cover plate 6 and the baffle 7 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 plate 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 plate 7 can rotate relative to the cover plate 6. When the through groove 705 on the baffle plate 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 plate 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 plate 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 groove 501, thereby mixing the raw materials on the cover plate 6.

[0024] To sum up, this device can add raw materials into 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 plate 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 material in the tank body 1, so that the pump body 3 can extract the liquid raw material more stably.

[0025] Combination Figure 9-13 As shown, the baffle plate 7 is elastically connected with an insertion rod 15, and the insertion rod 15 can move in the vertical direction relative to the baffle plate 7, and 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 colinear state; Furthermore, the plug rod 15 is configured as a "cross" shape as a whole, and a cross groove is provided on the baffle plate 7 to slide with the plug rod 15. The end faces of both ends of the plug rod 15 are elastically connected with protrusions 1501, and a groove 704 is provided on the inner wall of the cross groove to match the protrusion 1501. The end of the protrusion 1501 away from the plug rod 15 is a curved surface structure. Specifically, when the force between the protrusion 1501 and the groove 704 is large, the protrusion 1501 can When in use, when the baffle 7 falls to the vicinity of the bottom end of the tank body 1, a stirring rod 8 at the bottom end of the rotating shaft 5 will be inserted between the baffle 7 and the cover plate 6, thereby keeping the cover plate 6 and the baffle 7 relatively stable, and the insertion rod 15 is also aligned with the slot 606 on the cover plate 6. Therefore, when the baffle 7 moves to the vicinity of the bottom end of the tank body 1 so that the insertion rod 15 contacts the bottom surface of the tank body 1, the insertion rod 15 can be pushed up and inserted into the slot 606. , in order to lock the baffle plate 7 and the cover plate 6 to prevent relative rotation between the baffle plate 7 and the cover plate 6, and when the protrusion 1501 is aligned with the groove 704, the protrusion 1501 will be inserted into the groove 704, so as to maintain the stability of the insertion rod 15. Subsequently, when the baffle plate 7 and the cover plate 6 are driven to move upward, the baffle plate 7 and the cover plate 6 can pass through multiple stirring rods 8 in the vertical direction in sequence until the cover plate 6 moves to the vicinity of the top end of the tank body 1, and the top end of the insertion rod 15 is pressed to move downward. In this process, the protrusion 1501 is compressed and shrinks in the insertion rod 15, and the insertion rod 15 falls accordingly. In summary, the present scheme uses the insertion rod 15, when the cover plate 6 and the baffle plate 7 fall to the vicinity of the bottom end of the tank body 1, the stirring rod 8 at the bottom will be inserted between the baffle plate 7 and the cover plate 6, and the baffle plate 7 and the cover plate 6 can be locked by the insertion rod 15, thereby preventing the two from rotating relative to each other, which is beneficial to the resetting of the baffle plate 7 and the cover plate 6.
