[0025] The positioning assembly 4 includes a base 43 fixedly connected to the main cooling water jacket 1, a positioning ring 41 fixedly connected to the auxiliary cooling water jacket 3, a positioning rod 42 slidably connected to the positioning ring 41, a limiting ring 44 fixedly mounted on the top surface of the base 43, a disc-shaped shaft 45 rotatably arranged inside the base 43, a square rod 46 arranged in the internal cavity of the base 43 and fixedly connected to the disc-shaped shaft 45, a connecting screw 48 also arranged in the internal cavity of the base 43 and slidably connected to the square rod 46, and a fixing screw 48 fixedly mounted on the An auxiliary nut 47 is on the side wall of the inner cavity of the base 43 and is threadedly connected to the connecting screw 48; the connecting screw 48 can be threadedly connected to the positioning rod 42, and the positioning rod 42 is plugged into the limit ring 44. The square rod 46 is located on the end face of the inner cavity of the connecting screw 48 and is provided with a square limit block, which is also slidably connected to the connecting screw 48. There are two positioning rods 42 in total, and the number of connecting screws 48 is consistent with the number of positioning rods 42 to ensure the positioning effect of the overall structure to meet the alignment requirements of the crystallizer tube 2.

[0026] The base 43 is also provided with an operating assembly 7, which includes a transmission gear 71 fixedly mounted on the outer surface of the disc-shaped shaft 45, a ring gear 72 meshing with the transmission gear 71, a connecting bearing 73 that realizes the rotational connection between the ring gear 72 and the base 43, a fixed rod 74 fixedly mounted on the top surface of the ring gear 72, a pressure rod 76 slidably set on the fixed rod 74, a connecting rod 77 fixedly connected to the pressure rod 76, a friction ring 75 fixedly connected to the connecting rod 77, and a return spring 78 fixedly connected to the pressure rod 76 and the fixed rod 74 at both ends. A circular slide groove is provided on the base 43, and the fixed rod 74 is located in the internal cavity of the circular slide groove, and the top surface of the friction ring 75 is provided with friction patterns for enhancing the friction between the base 43. The connecting bearing 73 may include an inner ring layer, a central ball layer and an outer ring layer. The inner ring layer is configured to be fixedly connected to the base 43, and the outer ring layer is configured to be fixedly connected to the ring gear 72. The central ball layer is arranged between the inner ring layer and the outer ring layer to provide rotational support and reduce friction, so that the ring gear 72 can rotate inside the base 43. The number of transmission gears 71 is consistent with the number of connecting screws 48, and the ring gear 72 can be meshed and connected with two transmission gears 71 at the same time.

[0027] Working principle: because the base 43 is fixed on the main cooling water jacket 1, and the positioning ring 41 fixed on the auxiliary cooling water jacket 3 can be plugged into the positioning rod 42 on the base 43, the crystallizer tube 2 on the main cooling water jacket 1 and the crystallizer tube 2 on the auxiliary cooling water jacket 3 are aligned, and then the main cooling water jacket 1 and the auxiliary cooling water jacket 3 are assembled together by using the threaded connection relationship between the connecting bolt 12 and the threaded seat 11; and when multiple sets of auxiliary cooling water jackets 3 need to be combined on the main cooling water jacket 1 and a longer positioning rod 42 needs to be replaced, press the pressure rod 76 so that the pressure rod 76 is fixed on the fixing rod 7 4 slides downward, at this time, the friction ring 75 fixedly connected to the pressure rod 76 by the connecting rod 77 slides synchronously, so that a gap is generated between the friction ring 75 and the base 43, and then the circular groove on the base 43 is used as a path to push the fixing rod 74. The ring gear 72 fixedly connected to the fixing rod 74 also uses the connecting bearing 73 to rotate with the base 43. After pushing the fixing rod 74, the ring gear 72 rotates synchronously inside the base 43, and the transmission gear 71 meshing with the ring gear 72 uses the disc shaft 45 to rotate with the base 43, and the transmission gear 71 and the disc shaft 45 are As the ring gear 72 rotates, the square rod 46 fixed on the disc-shaped shaft 45 is slidably connected to the connecting screw 48, and the connecting screw 48 can also be fixed to the auxiliary nut 47 inside the base 43 for threaded connection. Therefore, after the disc-shaped shaft 45 rotates, the connecting screw 48 will be screwed out or screwed in from the base 43, so as to utilize the thread on the surface of the connecting screw 48 and the stroke of the connecting screw 48 to connect the positioning rod 42 to the base 43, or release the connection between the positioning rod 42 and the base 43, and the ring gear 72 can mesh with the two transmission gears 71 at the same time, so that the base 4 The states of the two connecting screws 48 on the upper and lower parts of the frame 43 will change simultaneously. After replacing the positioning rod 42 with a suitable length, the pressure rod 76 is loosened. Under the action of the return spring 78 fixedly connected to the pressure rod 76 and the fixing rod 74 at both ends, the gap between the friction ring 75 and the base 43 is eliminated. The friction ring 75 is in close contact with the base 43. The friction lines on the friction ring 75 will generate a certain friction force, which restricts the movement of the fixing rod 74 in the circular groove on the base 43. By locking the state of the ring gear 72, the state of the connecting screw 48 is further locked, thereby improving the stability of the overall structure.
