Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material conveying devices; in particular, it relates to a translational self-expanding sealing structure. Background Technology
[0002] Existing sealing devices mostly rely on the vertical approach of the sealing ring for sealing. After the moving part is in place, the sealing ring on one side is pushed to the fixed side to achieve sealing by means of electric hydraulics, etc. Furthermore, the accuracy of the sealing fit depends on the limit switch. Therefore, the above technology has the following shortcomings: (1) Excessive stroke compression can damage the device; insufficient stroke compression can lead to poor sealing. Therefore, traditional sealing technology can no longer achieve complete sealing without damaging the equipment. (2) Existing devices require multiple hydraulic lifting mechanisms to operate simultaneously to achieve sealing. This is not only costly, but also difficult to control the stroke of each hydraulic lifting mechanism to be completely consistent due to the simultaneous operation of multiple hydraulic lifting mechanisms. The inconsistent stroke of each hydraulic lifting mechanism leads to poor sealing of the contact surface. (3) Existing equipment requires regular replacement of hydraulic oil and sealing rings in the electric hydraulic mechanism. Limit switches are at risk of failure, which could cause the device to overturn if they fail. Therefore, based on the above shortcomings of existing equipment, a translational self-expanding sealing structure is urgently needed to solve the above technical problems. Utility Model Content
[0003] The purpose of this invention is to provide a translational self-expanding sealing structure.
[0004] This utility model is achieved through the following technical solution:
[0005] This utility model relates to a translational self-expanding sealing structure, including: a movable part 1 and a fixed part 8, wherein the movable part 1 and the fixed part 8 are connected by translational movement to the left and right or by translational movement to the right and left.
[0006] in,
[0007] The moving part 1 includes: chute A2, spring A3, edge sealing ring A4, slider guide groove A5, slider A6, and flexible sealing ring A7;
[0008] The fixed part 8 includes: chute B9, spring B10, edge sealing ring B11, slider guide groove B12, slider B13, and flexible sealing ring B14.
[0009] Preferably, the raised edge sealing ring A4 is disposed on the working surface of the moving part 1 by spring A3 and is operatively connected to the raised edge sealing ring B11. When the moving part 1 and the fixed part 2 move horizontally or vertically closer, the raised edge sealing ring A4 and the raised edge sealing ring B11, which are disposed on the contact surface, come into contact. Due to the compression of spring A3 and spring B10, they tend to be in complete contact. When the moving part 1 moves to the point where the fixed part 8 is in complete contact, the adjacent raised edge sealing rings A4 and B11 are tightly fitted together, thus achieving a seal.
[0010] Preferably, the warped edge sealing ring B11 is disposed on the working surface of the fixed part 8 by a spring B13 and is operatively connected to the warped edge sealing ring A4.
[0011] Preferably, both ends of the raised-edge sealing ring A4 and the raised-edge sealing ring B11 have raised-edge structures. The raised edges at both ends of the raised-edge sealing ring A4 extend in opposite directions to the opposite faces. For example, if the moving part 1 and the fixed part 8 are arranged sequentially left and right, and the moving part 1 is above the fixed part 8, the raised edge of the raised-edge sealing ring A4 extends upward, and the raised edge of the raised-edge sealing ring B11 extends downward; if the moving part 1 and the fixed part 8 are arranged sequentially top and bottom, and the moving part 1 is above the fixed part 8, the raised edge of the raised-edge sealing ring A4 extends to the left, and the raised edge of the raised-edge sealing ring B11 extends to the right.
[0012] Preferably, the chute A 2 is disposed on the side of the movable part 1; the chute B 9 is disposed on the side of the fixed part 8.
[0013] Preferably, the spring A3 is disposed between the chute A2 and the raised edge sealing ring A4; the raised edge sealing ring A4 is provided with a slider guide groove A5 and a slider A6.
[0014] Preferably, the slider A6 slides within the slider guide groove A5, which prevents the spring A3 from tilting radially under shear force, ensuring smooth operation.
[0015] Preferably, the spring B10 is disposed between the chute B9 and the raised edge sealing ring B11; the raised edge sealing ring B11 is provided with a slider guide groove B12 and a slider B13.
[0016] Preferably, the slider B13 slides within the slider guide groove B12. This prevents the spring B10 from tilting radially under shear force, ensuring smooth operation.
[0017] Preferably, the flexible sealing ring A7 is connected to the flexible sealing ring B14. This invention also adds a flexible sealing ring A7 to the movable part 1 and a flexible sealing ring B14 to the fixed part 8. When the raised edge sealing ring A4 and the raised edge sealing ring B11 are tightly fitted together for the first time, the flexible sealing rings A7 and B14 of both parts are connected to achieve a second tight fit, thus achieving a double seal.
[0018] The working principle of this utility model:
[0019] When the moving part 1 and the fixed part 2 move horizontally or vertically closer (where the power source of the moving part 1 comes from the moving part being mounted on the moving trolley or the translational device), the raised edge sealing ring A 4 and the raised edge sealing ring B11 with contact surfaces come into contact. Due to the compression of springs A 3 and B 10, they tend to come into complete contact. When the moving part 1 moves to the point where it comes into complete contact with the fixed part 8, the adjacent raised edge sealing rings A 4 and B 11 are tightly fitted together to achieve a seal. Finally, the flexible sealing ring A 7 set on the moving part 1 and the fixed part 8 cooperates with the flexible sealing ring B 14 to achieve a tight fit again, thus achieving the purpose of double sealing.
[0020] This utility model has the following advantages:
[0021] (1) The translational self-expanding sealing structure involved in this utility model can achieve expansion and long-lasting sealing by relying on the thrust generated when the moving part and the fixed part are in translational contact. No additional power is required. The structure is simple and reliable, thereby preventing dust and gas from overflowing during material conveying and discharge.
[0022] (2) The present invention provides a curved sealing ring in both the moving part and the fixed part to achieve sealing; in order to achieve more precise sealing, a flexible sealing ring is also added to achieve the purpose of double sealing. Attached Figure Description

[0032] The raised edge sealing ring A4 is disposed on the working surface of the moving part 1 by spring A3 and is operatively connected to the raised edge sealing ring B11. When the moving part 1 and the fixed part 2 move laterally closer, the raised edge sealing ring A4 and the raised edge sealing ring B11, which are disposed on the contact surface, come into contact. Due to the compression of spring A3 and spring B10, they tend to come into complete contact. When the moving part 1 moves to the fixed part 8 and comes into complete contact, the adjacent raised edge sealing rings A4 and B11 are tightly fitted together, thus achieving a seal.

[0040] The flexible sealing ring A7 is connected to the flexible sealing ring B14. This invention also adds a flexible sealing ring A7 to the movable part 1 and a flexible sealing ring B14 to the fixed part 8.

[0046] The raised edge sealing ring A4 is disposed on the working surface of the moving part 1 by spring A3 and is operatively connected to the raised edge sealing ring B11. When the moving part 1 and the fixed part 2 move horizontally or vertically closer, the raised edge sealing ring A4 and the raised edge sealing ring B11, which are disposed on the contact surface, come into contact. Due to the compression of spring A3 and spring B10, they tend to be in complete contact. When the moving part 1 moves to the fixed part 8 and is in complete contact, the adjacent raised edge sealing rings A4 and B11 are tightly fitted together, thus achieving a seal.
[0047] The warped edge sealing ring B11 is disposed on the working surface of the fixed part 8 by the spring B13 and is operatively connected to the warped edge sealing ring A4.

[0054] The flexible sealing ring A7 is connected to the flexible sealing ring B14. This invention also adds a flexible sealing ring A7 to the movable part 1 and a flexible sealing ring B14 to the fixed part 8. When the raised edge sealing ring A4 and the raised edge sealing ring B11 are tightly fitted together for the first time, the flexible sealing rings A7 and B14 of both parts are connected to achieve a second tight fit, thus achieving a double seal.

When the moving part 1 moves to the fixed part 8 and comes into complete contact, the adjacent raised edge sealing rings A4 and B11 are tightly fitted together to achieve a seal.
[0060] The warped edge sealing ring B11 is disposed on the working surface of the fixed part 8 by the spring B13 and is operatively connected to the warped edge sealing ring A4.
