[0002] Impregnation technology is an effective measure to solve casting leakage in the machinery manufacturing industry. It uses vacuum pressurization to allow the impregnating liquid to penetrate the casting's porous and defective parts. After solidification, the liquid fills the micropores, thus solving the leakage problem and achieving a sealed, pressure-bearing effect. After impregnation, the workpiece needs to be cleaned and dehydrated. Existing technologies also include some impregnation cleaning tanks, such as the Chinese utility model patent application number CN202221818904.1, entitled "An Impregnation Centrifugal Dehydration Device." This device uses a swing arm to rotate the dehydration tank cover around two bearing seats, thus opening and closing the top of the dehydration tank. It uses a cylinder and swing arm structure for opening and closing, but does not describe how the dehydrated liquid is recovered.

[0003] For example, Chinese utility model patent application number CN202023182444.1, entitled "A Vacuum Impregnation Centrifugal Dehydration Device", shows from the attached drawings in the specification that it also uses a cylinder and swing arm structure to achieve opening and closing, and does not describe how the dehydrated liquid is recovered.

[0006] Furthermore, the automatic top and bottom cover structure includes a dehydration tank cover, a tank cover connecting seat, a support gantry, a cylinder fixing seat, and a cylinder. Several of the support gantry are fixed to the upper end of the top plate, and the cylinder is horizontally fixed to the bottom end of the support gantry through the cylinder fixing seat. The dehydration tank cover is located directly below the support gantry, and the dehydration tank cover and the driving end of the cylinder are connected through the tank cover connecting seat.

[0007] Furthermore, two baffles are symmetrically fixed above the top plate on the inner side of the supporting gantry, and the liquid removal tank cover is located between the two baffles.

[0008] Furthermore, a tank cover support frame is provided between the outer side of the dehydration tank and the outer end of the top plate.

[0009] Furthermore, the dehydration and recovery structure includes a dehydration tank pipe and a dehydration and recovery tank, wherein the dehydration and recovery tank is connected to the bottom end of the dehydration tank via the dehydration tank pipe.

[0010] Furthermore, the desliming and recovery tank is equipped with an openable and closable desliming and recovery tank cover.

[0011] Furthermore, a float level gauge is installed on the liquid recovery tank.

[0023] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic recovery tank for dehydrating impregnated workpieces.

[0024] Example 1

[0025] This embodiment provides an automatic recovery tank for dehydrating impregnated workpieces, referring to... Figure 1 As shown, the system includes a dehydration tank 11, with a dehydration tank support frame 12 at its bottom for support. A top plate 13 is located at the top of the dehydration tank 11, extending to one side of the tank. A ring of baffles 14 surrounds the outer edge of the top plate 13, sealing its edges. This allows a small amount of solution carried out from the bottom of the dehydration tank cover 21 to drip onto the top plate 13 and flow back into the dehydration tank 11 through the central opening, preventing it from spilling onto the ground and polluting the factory environment. An opening is located in the center of the top plate 13 directly above the dehydration tank 11. Inside the dehydration tank 11 is a dehydration structure 3 for dehydrating the workpiece. In this embodiment, the dehydration structure 3 can use a rotary dehydration device for impregnating workpieces or other types of dehydration devices. The rotary dehydration device for impregnating workpieces dehydrates through centrifugal rotation; its specific structure and operation are not detailed in this embodiment. The bottom of the desliming tank 11 is provided with a desliming recovery structure 4 for recovering the deslimed liquid, and the top of the desliming tank 11 is provided with an automatic upper and lower cover structure for closing and opening the central opening of the top plate 13.

[0026] Reference Figures 1-2As shown, the automatic top and bottom cover structure includes a dehydration tank cover 21, a cover connecting seat 22, a support gantry 24, a cylinder fixing seat 25, and a cylinder 26. Two support gantry 24s are fixed to the upper end of the top plate 13. The cylinder 26 is horizontally fixed to the bottom end of the support gantry 24 via the cylinder fixing seat 25. In this embodiment, the cylinder 26 uses a single-rod push-pull cylinder from the prior art, with a maximum stroke of not less than 140cm. The dehydration tank cover 21 is located directly below the support gantry 24. The dehydration tank cover 21 and the driving end of the cylinder 26 are connected via the cover connecting seat 22. The cylinder 26 drives the dehydration tank cover 21 to move horizontally and linearly below the support gantry 24 via the cover connecting seat 22, closing and opening the opening in the center of the top plate 13 to prevent solution splashing out during dehydration in the dehydration tank 11. Two baffles 23 are symmetrically fixed above the top plate 13, inside the supporting gantry 24. The liquid removal tank cover 21 moves between the two baffles 23, limiting its movement and making it more stable. A tank cover support frame 27 is provided between the outer side of the liquid removal tank 11 and the outer end of the top plate 13 to increase the supporting force on the outer end of the top plate 13 and ensure structural strength.

[0027] Reference Figures 2-3 As shown, the dehydration and recovery structure 4 includes a dehydration tank pipe 41 and a dehydration and recovery tank 42. The dehydration and recovery tank 42 is connected to the bottom of the dehydration tank 11 via the dehydration tank pipe 41. The dehydration and recovery tank 42 is equipped with an openable and closable cover 45. A float level gauge 43 is installed on the dehydration and recovery tank 42. The float level gauge 43 uses a float switch level gauge in the prior art, which is triggered when the solution in the dehydration and recovery tank 42 reaches or falls below a certain depth. A recovery diaphragm pump 44 is fixed to the outside of the dehydration and recovery tank 42, and the inlet end of the recovery diaphragm pump 44 is connected to the bottom of the dehydration and recovery tank 42 via a pipe. The dehydration recovery structure 4 draws the dehydrated liquid from the dehydration tank 11 into the dehydration recovery tank 42 through the dehydration tank pipe 41. When the float level gauge 43 senses that the solution in the dehydration recovery tank 42 has reached a certain depth, it triggers the recovery diaphragm pump 44 to open, and discharges the solution in the dehydration recovery tank 42 through the pipe. When the float level gauge 43 senses that the solution in the dehydration recovery tank 42 has fallen below a certain depth, it triggers the recovery diaphragm pump 44 to close.

[0028] This utility model discloses an automatic recovery tank for dehydrating impregnated workpieces. During operation, cylinder 26 drives the dehydration tank cover 21 to move horizontally and linearly below the support frame 24 via the tank cover connecting seat 22. The dehydration tank cover 21 moves between two baffles 23, which limit the movement of the dehydration tank cover 21, making its movement more stable. The dehydration tank cover 21 closes the opening in the center of the top plate 13 to prevent solution from splashing out during dehydration in the dehydration tank 11. After closing, the dehydration structure 3 dehydrates in the dehydration tank 11, and the dehydrated solution is drained and recovered into the dehydration recovery tank 42 through the dehydration tank pipe 41. When the float level gauge 43 senses that the solution in the dehydration recovery tank 42 has reached a certain depth, it triggers the recovery diaphragm pump 44 to open, discharging the solution in the dehydration recovery tank 42 through the pipe. When the float level gauge 43 senses that the solution in the dehydration recovery tank 42 has fallen below a certain depth, it triggers the recovery diaphragm pump 44 to close. After the liquid removal is completed, the cylinder 26 drives the liquid removal tank cover 21 to open, and the workpiece in the liquid removal tank 11 is taken out from the opening in the center of the top plate 13, thereby realizing the automatic closing and opening of the liquid removal tank and the automatic recovery of the liquid removed.
