TECHNICAL FIELD

[0001] The utility model relates to the technical field of compression rotary oil cylinder device, specifically to a high sealing compression rotary oil cylinder device based on magnesium smelting. BACKGROUND

[0002] In the magnesium smelting process, the reduction pot as the core reaction container needs to be operated for a long time under high temperature, high pressure and strong corrosive environment, and the sealing performance of the reduction pot directly affects the reaction efficiency, energy consumption and production safety; Traditional manual locking is prone to uneven stress, poor sealing, and increased leakage risk, and relies on manual adjustment of compression force, which is labor-intensive and difficult to adapt to continuous production needs.

[0020] Preferably, the use method comprises the following steps:

[0021] S1, preparation before starting the equipment: confirming that the oil level of the hydraulic pump of the hydraulic table is normal, the electromagnetic valve block is connected stably, checking that there is no leakage between the release inlet, the pressing inlet, and the oil supply pipeline of the four rotary oil cylinders, checking the meshing state of the guide rod and the spiral groove, ensuring that the piston rod rotates smoothly, testing the lifting function of the lifting wheel assembly of the canning vehicle, and ensuring that the lifting function is normal.

[0022] S2, positioning of the filling can: adjusting the height of the canning vehicle through the lifting column, aligning the filling can with the axis of the reduction can, finely adjusting the position of the can cover through the horizontal slide rail and the vertical slide rail, ensuring that the center line of the filling can is aligned with the center line of the reduction can and is lifted up, and until the can cover completely matches the reduction can.

[0028] 3. This utility model, by installing four rotating oil cylinders and a solenoid valve block, realizes synchronous pressing and releasing of multiple oil cylinders, ensuring uniform circumferential pressure distribution in the reduction tank, and solving the problems of easy tilting and unstable sealing of traditional single-point pressing.

[0029] 4. This utility model, by installing a hydraulic pump and multi-stage oil pipelines, realizes graded oil delivery and stable pressure control. The hydraulic pump provides a high-pressure oil source, which is distributed to four rotary cylinders through multi-stage pipelines. Combined with the intelligent switching of the solenoid valve block, the oil pressure and flow rate of the pressing and releasing actions are precisely adjusted to ensure that each cylinder responds synchronously. This solves the problems of large pressure fluctuations and slow response in traditional single oil circuit systems, and significantly improves the sealing and pressing efficiency.

[0045] Furthermore, the outer wall of the reduction tank 11 provides installation positions for the first rotary cylinder 12, the second rotary cylinder 13, the third rotary cylinder 14, and the fourth rotary cylinder 15. The outer wall of the cylinder body 24 has a release inlet 25 and a clamping inlet 26.
