Description

Technical Field

[0001] The utility model relates to the field of molecular distillation sealing equipment, in particular to an air-cooled molecular distillation magnetic sealing device. Background Art

[0002] Molecular distillation is a distillation method operated under high vacuum. It separates liquid mixtures by utilizing the differences in evaporation rates of the components in the liquid. In order to maintain the high vacuum state inside the equipment, a sealing device is usually required to seal the equipment. Currently, commonly used sealing devices include mechanical sealing structures and magnetic sealing structures.

[0003] The mechanical seal structure generally relies on a pair or several pairs of end faces that slide relative to the shaft perpendicular to the shaft to maintain contact under the action of fluid pressure and the elastic force of the compensation mechanism and is equipped with an auxiliary seal to achieve leakage-proof shaft sealing. However, this structure will be subject to greater friction during actual use, which will lead to wear and tear, and requires regular maintenance and replacement.

[0004] The magnetic sealing structure uses the magnetic field of the magnetic material to attract the compensation ring assembly and the non-compensation ring assembly to each other, so that the friction surfaces of the compensation ring and the non-compensation ring can fit tightly. It not only simplifies the structural components, but also reduces wear during use and has a longer service life. In order to ensure that the magnetic sealing structure works in a low temperature state, an air inlet is generally provided on the surface of the connecting cover, and an air flow channel is designed inside the connecting cover so that the air flow can reach the air outlet. However, when the air flow enters the air inlet, it usually contacts the inside of the air inlet, resulting in uneven distribution of the air flow inside the air inlet, thereby reducing the air intake efficiency.

[0005] Therefore, it is necessary to provide a new air-cooled molecular distillation magnetic sealing device to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an air-cooled molecular distillation magnetic sealing device.

[0007] The air-cooled molecular distillation magnetic sealing device provided by the utility model comprises a molecular distillation device, the molecular distillation device comprises a magnetic sealing structure and a connecting cover, an air inlet is provided on the surface of the connecting cover, and the air inlet is communicated with the inside of the magnetic sealing structure, and a flow dividing component is provided inside the air inlet;

[0008] The diversion component includes a mounting part and a movable block, wherein two ends of the mounting part are respectively fixedly connected to the top and bottom ends of the inner side of the air inlet, and the movable block is sleeved on the outside of the mounting part. The movable block is rotatably connected to the mounting part, and movable plates are fixedly provided at both ends of the movable block, and a plurality of air holes are provided on the surface of the movable plate.

[0009] Preferably, the mounting member comprises two mounting posts, one end of the two mounting posts being fixedly connected to the top end and the bottom end of the inner side of the air inlet respectively.

[0010] Preferably, a universal ball is movably provided at one adjacent end of the two mounting posts.

[0011] Preferably, a filter is provided at the place where the air inlet communicates with the magnetic sealing structure.

[0012] Preferably, the multiple air holes arranged on the surface of the movable plate are all arranged in a circular shape.

[0013] Preferably, the top and bottom of the movable block are provided with slots matching the universal ball.

[0014] Compared with the related art, the air-cooled molecular distillation magnetic sealing device provided by the utility model has the following beneficial effects:

[0015] 1. When the airflow flows into the magnetic sealing structure through the air inlet, since the movable block and the mounting part are rotatably connected, when the airflow contacts the surface of the movable plates arranged at both ends of the movable block, the movable block and the movable plate will rotate along the central axis of the mounting part. Through the rotation of the movable plate, the airflow is more evenly distributed inside the air inlet, which can improve the air intake efficiency to a certain extent.

[0016] 2. Through the rotation of the movable plate, the noise and vibration generated by the impact of the airflow can be absorbed and dispersed to a certain extent, thereby reducing the impact of the airflow on the inner wall of the air inlet and reducing noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The magnetic sealing structure includes a support cover 12, an outer magnetic sleeve 13, an isolation cover 14 and an inner rotor 15. The bottom of the support cover 12 is fixedly connected to the top of the molecular distillation device 1, the outer magnetic sleeve 13 is located inside the support cover 12, the isolation cover 14 is located inside the outer magnetic sleeve 13, a gap for air flow is left between the isolation cover 14 and the outer magnetic sleeve 13, and an air outlet 16 is provided at the bottom of the isolation cover 14, and the inner rotor 15 is located inside the isolation cover 14;

[0032] When the air flow flows through the air inlet 3 to the gap between the isolation cover 14 and the outer magnetic sleeve 13, since the adjacent ends of the two mounting columns 8 are each provided with a universal ball 9, and the universal ball 9 is located inside the slots 11 set at the top and bottom of the movable block 5, when the air flow contacts the surface of the movable plate 6 set at both ends of the movable block 5, the movable block 5 and the movable plate 6 will rotate along the central axis of the support column. Through the rotation of the movable plate 6, the air flow is more evenly distributed inside the air inlet 3.

[0033] The working principle provided by the utility model is as follows: when the airflow flows through the air inlet 3 to the gap between the isolation cover 14 and the outer magnetic sleeve 13, since the adjacent ends of the two mounting posts 8 are each provided with a universal ball 9, and the universal ball 9 is located inside the card slots 11 provided at the top and bottom of the movable block 5, when the airflow contacts the surface of the movable plates 6 provided at both ends of the movable block 5, the movable block 5 and the movable plate 6 will rotate along the central axis of the support column. Through the rotation of the movable plate 6, the airflow is more evenly distributed inside the air inlet 3. Since the movable block 5 is connected to the universal ball 9 provided on the support column through the card slot 11, when the movable block 5 rotates, the friction between the movable block 5 and the support column can be effectively reduced, thereby improving the smoothness of the rotation of the movable block 5.

[0034] The rotation of the movable plate 6 can absorb and disperse the noise and vibration generated by the impact of the airflow to a certain extent, thereby reducing the impact of the airflow on the inner wall of the air inlet 3 and reducing the noise. The filter 10 can reduce the dust and impurities entering the isolation cover 14, further improving the internal environment.

[0035] The multiple air holes 7 arranged on the surface of the movable plate 6 can reduce turbulence and eddy currents when the airflow passes through, thereby reducing fluid resistance, allowing the airflow to pass through the movable plate 6 more smoothly and reducing the capacity loss of the airflow. At the same time, the circular air holes 7 help the airflow to be evenly distributed on the surface of the movable plate 6, reducing the concentration and deviation of the airflow.
