[0023] Example:

[0024] Reference Figure 1 and Figure 2As shown, a one-way sealed cylinder for a cooling water hole of a crystallizer comprises a cylinder body 1 of a barrel-shaped structure, a sealing cover with a through hole 15 is fixedly arranged at its open end, a piston rod 4 is slidably arranged in the sealing cover, a piston head is arranged at one end of the piston rod 4 located outside the cylinder body 1, and a mounting seat 2 is arranged at the other end located inside the cylinder body 1, a bellows air spring 6 is sleeved on the piston rod 4, and both ends of the bellows air spring 6 are respectively fixedly connected to the sealing cover and the mounting seat 2, a connecting shaft 11 is arranged on the end face of the cylinder body 1 away from the sealing cover, a mounting plate 9 with a mounting hole 10 is fixed on the connecting shaft 11, and an air hole 14 connected to the inside of the cylinder body 1 is arranged on the side wall of the end face of the cylinder body 1;

[0025] One end of the through hole 15 is connected to the interior of the bellows air spring 6 , and the other end is adjacent to the piston head.

[0026] A closed space is formed inside the cylinder body 1 through the sealing cover, the air pressure inside the cylinder body 1 can be controlled through the air hole 14, the cooling water hole can be closed through the piston head, and the through hole 15 is convenient for the bellows air spring 6 to inhale air when it is extended or retracted. The two ends of the bellows air spring 6 are respectively fixed on the sealing cover and the mounting seat 2, and the sealing cover is fixedly connected to the cylinder body 1, so that the bellows air spring 6 can drive the mounting seat 2 to move when it is extended or retracted, and the movement of the mounting seat 2 can drive the piston rod 4 to move, and then drive the piston head to move. The movement of the piston head can close or open the cooling water hole, thereby controlling the amount of cooling water.

[0027] The sealing cylinder is mounted on the crystallizer through a mounting plate 9 with mounting holes 10 and fixed through bolts matching the mounting holes 10 .

[0028] A sealing disk 7 is fixedly provided at a position of the piston rod 4 close to the piston head. The sealing disk 7 is located between the piston head and the sealing cover, and a sealing gasket 8 is covered on the surface of the sealing disk 7 .

[0029] The sealing head 5 is used to block the cooling water hole, and the sealing effect is further improved through the sealing gasket 8 on the sealing disk 7 to prevent the cooling water from penetrating from the gap, thereby ensuring the accuracy of the cooling water volume control.

[0030] The outer wall of the cylinder body 1 is provided with annular grooves 12 on both sides of the air control, and a sealing ring 13 is clamped in the annular groove 12 .

[0031] The sealing effect of the air hole 14 on the outer wall of the cylinder body 1 is improved by the sealing ring 13 to ensure that when the air hole 14 is delivering air, the air pressure inside the cylinder body 1 can be increased, thereby compressing the bellows air spring 6, so that the piston rod 4 extends, ensuring the normal operation of the sealed cylinder.

[0032] One end of the piston rod 4 located in the cylinder body 1 is provided with a thread, and the mounting seat 2 is provided with a threaded hole, and the end of the piston rod 4 is threadedly connected in the threaded hole.

[0033] The mounting seat 2 is threadedly connected to the piston rod 4 for easy assembly.

[0034] The mounting seat 2 includes a connecting seat and an annular baffle. A threaded hole is arranged on one end surface of the connecting seat, and an annular baffle is arranged on the outer side wall of the connecting seat. The bellows air spring 6 is fixed on the annular baffle.

[0035] The connecting seat is used to connect with the piston rod 4, and the annular baffle is convenient for connecting with the bellows air spring 6.

[0036] When in use, the sealing cylinder is installed at the cooling water hole of the crystallizer through the mounting plate 9 and the bolts. The distance between the sealing head 5 and the end face of the water hole is less than the stroke of the piston rod 4. Under normal circumstances, the water hole forms a passage, and the two water chambers are connected. When the amount of cooling water needs to be reduced, the air path is connected, so that the gas is transported from the air hole 14 to the inside of the cylinder body 1. The air pressure inside the cylinder body 1 rises, and the bellows air spring 6 inside it is squeezed, causing the bellows air spring 6 to contract. The contraction of the bellows will drive the mounting seat 2 to move toward the sealing seat 3, and the sealing seat 3 is connected to the piston rod 4, thereby driving the piston rod 4 to slide toward the sealing seat 3, so that the sealing head 5 moves toward the water hole. Finally, the sealing head 5 blocks the water hole, and the sealing gasket 8 seals the water hole around and closes the water hole, thereby closing the passage between the two water chambers, thereby maintaining the cooling water injection state and reducing the amount of cooling water. When the amount of cooling water is to be increased, the air source is closed to reduce the air pressure in the cylinder 1, and the bellows air spring 6 absorbs air from the through hole 15 and stretches, driving the mounting seat 2 to move, and then driving the sealing head 5 to move. The sealing head 5 is separated from the water hole, thereby connecting the two water chambers and increasing the cooling water supply.

[0037] In actual use, the sealing seat 3 is welded and fixedly connected to the cylinder body 1 to ensure the sealing inside the cylinder body 1 and the normal use of the sealed cylinder.

[0038] The mounting plate 9 is welded and fixed to the connecting shaft 11 to ensure the firmness of the mounting plate 9 and ensure that the sealing cylinder can be firmly mounted on the crystallizer through the mounting plate 9. At the same time, the mounting plate 9 ensures that the sealing head 5 of the sealing cylinder can accurately block the water hole during work.

[0039] The cooling water volume of the ingot can be effectively and controllably adjusted to ensure the performance structure of the ingot and prevent the ingot quality from being unstable due to uncontrollable cooling water volume.

[0040] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
