The structure is ingenious, and the technical problems existing in the prior art such as poor sealing of the tank opening sealing structure and inability to withstand the ultra-high pressure of steam explosion working in the tank are solved.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A built-in sealed can lid structure comprises: a can body, on which a material opening is opened, and the material opening is arranged in an elliptical shape; and a can lid, which is arranged in an elliptical shape with a size slightly larger than the material opening, extends under the material opening and seals the material opening by pressing upwards.

[0008] Preferably, the elliptical major axis a1 of the material opening is larger than the elliptical minor axis b2 of the can cover, and the can cover extends obliquely downward into the material opening or is taken out obliquely upward from the material opening with its elliptical minor axis b2 parallel to the elliptical major axis a1 of the material opening and forming an angle α with the material opening.

[0009] Preferably, α=15°-20°.

[0010] Preferably, the device further comprises: a driving mechanism, wherein the driving mechanism is connected to the tank cover and drives the tank cover to rotate and translate and lift in an inclined state, thereby blocking or opening the material opening.

[0011] Preferably, the driving mechanism comprises: a movable arm, which is mounted on the driving seat at an angle α with the material port and can be telescopically moved along its length direction; a lifting assembly, which is mounted on the telescopic end of the movable arm and can be lifted and lowered; and a rotating assembly, which is mounted on the lifting end of the lifting assembly and can rotate, and the tank cover is hingedly mounted on the rotating end of the rotating assembly.

[0012] Preferably, an installation space is provided in the tank body below the material port, and a dimension L from the center of the installation space to any point on its edge is larger than half of the dimension of the elliptical major axis a2 of the tank cover, so that the tank cover can be extended into or taken out of the material port by coordinated translation and lifting actions in a tilted state, and the tank cover can be rotated in the installation space to adjust to a state in which its elliptical minor axis b2 is parallel to the elliptical minor axis b1 of the material port or to the elliptical major axis a1 of the material port.

[0013] Preferably, the installation space is configured as a circular space.

[0014] Preferably, in the blocked state, the tank cover presses the bottom edge of the material opening by at least 30 mm.

[0015] Preferably, the tank cover further comprises: a sealing member, wherein the sealing member is arranged around the top edge of the tank cover, and in a blocked state, the sealing member is interference-fitted with the bottom edge of the material opening to perform sealing.

[0016] Preferably, the sealing member is configured as a sealing ring, and is made of a wear-resistant, corrosion-resistant, high-temperature-resistant, and high-pressure-resistant material, including polytetrafluoroethylene material.

[0017] Preferably, the can lid includes a can lid body. An annular lower convex edge extends upward from the top edge of the can lid body. An upper convex edge with a width dimension greater than that of the lower convex edge extends upward from the top of the lower convex edge. An outer embedding groove is formed between the outer peripheral edge of the upper convex edge, the outer peripheral surface of the lower convex edge, and the outer edge of the can lid body. An inner embedding groove is formed between the inner peripheral edge of the upper convex edge, the inner peripheral surface of the lower convex edge, and the top surface of the can lid body. The seal is arranged in an "冖" shape and is clamped on the upper convex edge, with both ends extending downward into the outer embedding groove and the inner embedding groove respectively.

After extending into the material opening, through a rotational action, the short axis of the can lid corresponds to the short axis of the material opening and is combined with a lifting action to seal the material opening in an upward pressing manner from below. The structure and action are very ingenious.

[0022] (3) By setting a large-sized elliptical can lid to match a small-sized elliptical material opening in the present utility model, when the sealing is in place, the top edge of the can lid can press against the bottom edge of the material opening, and the sealing effect and anti-pressure effect are excellent. Further, an interference fit is set between the seal and the bottom edge of the material opening to strengthen the sealing effect, and the seal is made of wear-resistant, corrosion-resistant, high-temperature-resistant, and high-pressure-resistant materials, which is especially suitable for applications in the steam explosion field.

[0034] Embodiment 1

[0035] like Figure 1-2 As shown, a built-in sealed can cover structure comprises: a can body 1, on which a material opening 11 is opened, and the material opening 11 is arranged in an elliptical shape; and a can cover 2, which is arranged in an elliptical shape with a size slightly larger than the material opening 11, and extends under the material opening 11 and seals the material opening 11 by pressing upwards.

[0036] Preferably, the elliptical major axis a1 of the material opening 11 is larger than the elliptical minor axis b2 of the tank cover 2 .

[0037] In this embodiment, a built-in tank cover structure is adopted. The tank cover 2 extends into the material opening 11 of the tank body 1 and seals the material opening 11 from the inside by pushing up. This structure can not only withstand the ultra-high pressure when working in the tank, but also use the ultra-high pressure to enhance the sealing effect of the material opening. The greater the pressure in the tank body 1, the tighter the sealing of the tank cover to the material opening is, and it is not easy to leak. The design is ingenious.

[0038] In addition, in the event of air leakage, the manipulator activates the tank cover 2 through high-frequency vibration, and utilizes the high internal pressure of the tank body 1 to form vibration stamping, thereby further improving the sealing effect and avoiding air leakage.

[0039] As a preference, Figure 2 As shown, the can cover 2 extends obliquely downward into the material opening 11 or is taken out obliquely upward from the material opening 11 with its elliptical minor axis b2 parallel to the elliptical major axis a1 of the material opening 11 and forming an angle α with the material opening 11 .

[0040] Specifically in the capping structure, a large-sized elliptical can cover 2 is arranged to match the small-sized elliptical material opening 11, and a special assembly action is adopted. That is, during the capping operation, the can cover 2 is smoothly inserted under the material opening 11 with its short axis corresponding to the direction of the long axis of the material opening 11 and the can cover is smoothly inserted under the material opening 11 by the translation and descending coordination actions in an inclined state. Then, the can cover 2 and the material opening 11 are made parallel to each other through the rotation action and the short axis of the can cover 2 corresponds to the short axis of the material opening 11. Then, the can cover 2 is capped on the material opening 11 through the lifting action. The can cover 2 can be taken out from the material opening 11 by the reverse action. The structure and action are very ingenious.

[0041] See also Figure 3 As shown, states (1) to (3) show that the can cover 2 is extended into the material opening 11 (sinking and moving forward) with its short axis tilted to the long axis of the material opening 11; state (4) shows that the can cover 2 is completely inserted under the material opening 11 and rotated to a horizontal state; state (5) shows that the can cover 2 retreats to be concentric with the material opening 11 and rotates 90° so that its long axis is aligned with the long axis of the material opening; state (6) shows that the can cover 2 is lifted up to be sealed against the material opening 11.

[0042] Preferably, α=15°-20°.

[0043] As a preference, Figure 1 As shown, it also includes: a driving mechanism 3, which is connected to the tank cover 2, and drives the tank cover 2 to rotate and translate and rise and fall in an inclined state, so as to block or open the material opening 11.

[0045] It should be noted that the rotating component 33 is used to drive the tank cover 2 to rotate so that the tank cover 2 can switch between a state in which the long axis is aligned with the long axis of the material opening 11 or a state in which the short axis is aligned with the long axis of the material opening 11. The tank cover 2 is hingedly mounted on the rotating end of the rotating component 33, so that when the lifting component 32 drives the tank cover 2 to rise to contact the bottom edge 110 of the material opening 11, the tank cover 2 can automatically adjust to a horizontal state that is aligned with the center line of the material opening 11 and parallel to each other, thereby effectively blocking the material opening 11.

[0046] As a preference, Figure 4-5As shown, an installation space 12 is provided in the can body 1 below the material opening 11, and a dimension L from the center of the installation space 12 to any point on its edge is larger than half of the dimension of the elliptical major axis a2 of the can cover 2, so that the can cover 2 can be extended into or taken out of the material opening 11 by translation and lifting coordination in a tilted state, and the can cover 2 can be rotated in the installation space 12 to adjust to a state in which its elliptical minor axis b2 is parallel to the elliptical minor axis b1 of the material opening 11 or to the elliptical major axis a1 of the material opening 11.

[0047] Preferably, the installation space 12 is configured as a circular space.
