A plurality of partition rods 7 are fixedly connected inside the placement frame 6. The placement frame 6 is divided into a plurality of placement cavities 8 by the plurality of partition rods 7. An ejector pin 9 is fixedly connected to the bottom of the placement cavity 8.

[0026] Refer to Figure 1 , Figure 2 and Figure 3 , moving rods 10 are fixedly connected to both the left and right sides of the placement frame 6. A rotating rod 11 is threadedly connected to the inner cavity of one side moving rod 10. A motor 12 is fixedly installed on the top of the rotating rod 11. A limiting rod 13 is movably installed in the inner cavity of the other side moving rod 10. An extraction hole 14 is opened on the right side of the reaction tank 2. A vacuum extraction mechanism 5 is fixedly installed on the right side of the extraction hole 14. The vacuum extraction mechanism 5 includes an extraction pipe 501 and a vacuum pump 502. One end of the extraction pipe 501 is fixedly installed in the inner cavity of the extraction hole 14, and the vacuum pump 502 is fixedly installed at the other end of the extraction pipe 501.

[0027] Adopting the above solution: By starting the motor 12, the motor 12 drives the rotating rod 11 to rotate, and the moving rod 10 on the surface of the rotating rod 11 can move on the rotating rod 11, thereby facilitating the placement and removal of workpieces.

[0028] Refer to Figure 1 ,Figure 4 and Figure 5 Inside the wall of the reaction tank 2, a heating mechanism 4 is fixedly installed. The heating mechanism 4 includes a circulating water pipe 401, a water storage tank 402, a heater 403, and a circulating pump 404. The circulating water pipe 401 is fixedly installed inside the wall of the reaction tank 2. The water storage tank 402 is fixedly installed at one end of the circulating water pipe 401. The heater 403 is fixedly installed inside the water storage tank 402. The circulating pump 404 is fixedly installed on the top of the water storage tank 402. The circulating pump 404 is connected to the other end of the circulating water pipe 401. On the left side of the reaction tank 2, a mounting seat 15 is fixedly installed. On the top of the mounting seat 15, a connecting arm 16 is fixedly installed. The connecting arm 16 is fixedly connected to the sealing cover 17.

[0030] Working principle: When in use, the staff opens the sealing cover 17, places the workpiece in the placement cavity 8 of the placement frame 6. The bottom of the workpiece is placed on the top of the ejector pin 9. Then, an appropriate amount of penetration liquid is injected into the reaction tank 2. The sealing cover 17 is covered. The vacuum pump 502 is started. The reaction tank 2 is evacuated through the suction pipe 501 to make the inside of the tank in a vacuum state. Then, the motor 12 is started. The motor 12 drives the rotating rod 11 to rotate, and then the moving rod 10 drives the placement frame 6 to descend, so that the penetration liquid completely submerges the workpiece. During the processing of the workpiece, the heating mechanism 4 heats the inner wall of the reaction tank 2 to accelerate the penetration efficiency. When the penetration is completed, the rotating rod 11 rotates in the reverse direction, the moving rod 10 drives the placement frame 6 to rise, and the staff can open the sealing cover 17 to take out the workpiece.
