Mechanical seals are easily damaged after long-term operation, leaking, and causing safety hazards.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0044] When dismantling common mechanical seal structures, the bolts are usually removed using tools such as wrenches, and then the flange or sealing gasket is pulled out using a screwdriver. The coking between the flange and the sealing gasket results in a tight connection between the two, while the method of prying them open with a screwdriver has a single force point and deviation, which can easily damage the flange or sealing gasket during dismantling, and the dismantling cannot be performed quickly and effectively, and cannot meet the working requirements of the auxiliary dismantling device.

[0045] The utility model provides a mechanical seal disassembly device.

[0046] See also Figures 1 to 3 In one embodiment of the present utility model, the mechanical seal disassembly device 100 comprises:

[0047] Mounting mechanism 1;

[0048] Separation mechanism 2, the separation mechanism 2 comprises:

[0049] A separation ring 21 is rotatably disposed on one side of the mounting mechanism 1; and

[0050] At least one separation rod 22 is slidably disposed on the outer periphery of the separation ring 21 to move closer to or away from the mechanical seal, so that the separation rod 22 and the mechanical seal are locked or released. In the locked state, the mechanical seal rotates synchronously with the separation ring 21 through the separation rod 22.

[0051] In the technical solution of the utility model, the separation mechanism 2 includes a separation ring 21 and at least one separation rod 22, and the separation ring 21 is rotatably arranged on one side of the mounting mechanism 1, and the separation rod 22 is slidably arranged along the outer periphery of the separation ring 21. When the mechanical seal needs to be disassembled, the operator first moves the separation ring 21 close to the mechanical seal, and as the separation ring 21 gradually approaches the mechanical seal, the separation rod 22 is driven to move close to the mechanical seal until it is inserted into the connection of the mechanical seal and is locked with the mechanical seal, so that the mechanical seal rotates synchronously with the separation ring 21 through the separation rod 22, so that the mechanical seal can be smoothly opened and separated from the connection. When the separation is completed, the separation ring 21 moves away from the mechanical seal connection, and the separation rod 22 moves toward the center of the separation ring 21 to release the mechanical seal, and the mechanical seal can be removed. This rotary separation method has obvious advantages over the traditional method of prying with tools such as a screwdriver. It not only improves the integrity of the separation and reduces the damage to the mechanical seal structure caused by uneven force, but also greatly increases the convenience of the separation process.

[0052] Specifically, in this embodiment, the size of the separation ring 21 is not specifically limited, and can be adjusted according to the actual size of the mechanical seal. In addition, the number of separation rods 22 is not specifically limited, as long as there are multiple separation rods 22 along the outer circumference of the separation ring 21, the mechanical seal can be evenly supported and separated. It should be noted that the shape of the separation rod 22 is not specifically limited, and can be cylindrical or conical, as long as it can facilitate the separation of the mechanical seal and the connection.

[0053] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 There are multiple separation rods 22, and the multiple separation rods 22 are arranged in a circular array along the outer circumference of the separation ring 21. The separation rods 22 are arranged in an array, which can increase the contact points with the mechanical seal and expand the force-bearing positions; further, the separation rods 22 are evenly spaced on the separation ring 21. Since the separation rods 22 are evenly spaced along the outer circumference of the separation ring 21, this design also ensures uniform application of force during the separation process, further reducing the risk of damage to the mechanical seal due to the separation operation.

[0054] In the embodiments of the present invention, please refer to Figure 3The separation rod 22 has an insertion end 221 and an embedding end 222 relative to each other. The insertion end 221 is provided with an inclined surface, which is inclined with respect to the radial direction of the separation ring 21 in the direction close to the mechanical seal. The design of the inclined surface enables the separation rod 22 to be smoothly inserted into the gap at the connection of the mechanical seal at a specific angle when inserted into the mechanical seal, thereby reducing the risk of damage to the mechanical seal. In addition, the cross-sectional area of ​​the insertion end 221 changes in an increasing state along the direction close to the embedding end 222. This design enables the separation rod 22 to smoothly insert into the mechanical seal along the inclined surface. As the insertion end 221 continues to go deeper, it can provide a gradually increasing support area, thereby providing a more uniform and stable support force. In this way, the mechanical seal can be smoothly opened and separated from the connection. In this way, not only can the force applied to the mechanical seal be better dispersed, but also the stable contact between the separation rod 22 and the mechanical seal can be ensured, thereby improving the reliability and efficiency of the separation process. At the same time, due to the inclined surface design of the insertion end 221, the separation rod 22 can be automatically aligned and positioned during the insertion process, further simplifying the operation steps and improving the convenience of separation.

[0055] In an embodiment of the utility model, the separation mechanism 2 also includes a first elastic member (not shown in the figure), which is arranged inside the separation ring 21 to connect the separation ring 21 and the embedded end 222 so that the separation rod 22 has a tendency to move away from the mechanical seal; the first elastic member can be a tension spring. When the separation rod 22 is driven by an external structure to move close to the mechanical seal, the first elastic member will be stretched. After the separation is completed, the elasticity of the first elastic member will drive the separation rod 22 to return to the initial state, facilitating the next separation.

[0056] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The mechanical seal disassembly device 100 further includes a driving mechanism 3, which is drivingly connected to the separation rod 22 to drive the separation rod 22 to move closer to or away from the mechanical seal. The design of the driving mechanism 3 can be selected in different types according to actual needs and application scenarios, such as electric drive, pneumatic drive or hydraulic drive. These driving modes can provide sufficient power to ensure that the separation rod 22 can successfully complete the separation of the mechanical seal.

[0057] In the embodiments of the present invention, please refer to Figure 4 , the interior of the separation ring 21 forms a separation chamber, and the driving mechanism 3 includes:

[0058] The driving box 31 is fixed to the separation ring 21. The interior of the driving box 31 forms a regulating chamber connected to the separation chamber, and both the separation chamber and the regulating chamber are filled with gas.

[0059] The adjusting rod 32 is threadedly connected to the driving box 31; and

[0060] The slide plate 33 is disposed in the regulating chamber and fixedly connected to the regulating rod 32 , and the regulating rod 32 drives the slide plate 33 to slide back and forth in the regulating chamber so that the gas moves toward or away from the separation chamber, so that the separation rod 22 moves close to or away from the mechanical seal.

[0061] Specifically, the drive box 31 is an important component of the drive mechanism 3, and it is fixed on the separation ring 21. The inside of the drive box 31 forms an adjustment chamber connected to the separation chamber, and the separation chamber and the adjustment chamber are filled with gas. This design enables the drive box 31 to control the movement of the separation rod 22 by changing the gas pressure in the separation chamber. The adjustment rod 32 and the drive box 31 are threadedly connected. This connection method not only ensures the firm connection between the adjustment rod 32 and the drive box 31, but also allows the adjustment rod 32 to rotate on the drive box 31, thereby driving the slide plate 33 to slide back and forth in the adjustment chamber, so that the gas can be moved toward or away from the separation chamber by the sliding of the slide plate 33, thereby changing the gas pressure in the separation chamber. In actual operation, when it is necessary to make the separation rod 22 close to the mechanical seal, the drive box 31 will drive the slide plate 33 to move in the direction of the separation chamber, so that the gas is compressed and moves toward the separation chamber, thereby increasing the gas pressure in the separation chamber. This increase in pressure will push the separation rod 22 to move toward the mechanical seal until the desired separation position is reached. On the contrary, when it is necessary to move the separation rod 22 away from the mechanical seal, the drive box 31 will drive the slide plate 33 to move away from the separation chamber, so that the gas flows from the separation chamber to the adjustment chamber, thereby reducing the gas pressure in the separation chamber. This pressure reduction will cause the separation rod 22 to move away from the mechanical seal, thereby achieving the evacuation of the separation rod 22. In this way, the separation rod 22 can be accurately controlled and driven, and the efficiency and safety of the mechanical seal separation process are improved. At the same time, because the drive mechanism 3 uses gas as the driving medium, the entire separation process is more stable and reliable, reducing the potential risk of damage.

[0062] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 The mechanical seal disassembly device 100 also includes a rotating mechanism 4, one end of which is fixedly connected to the mounting mechanism 1, ensuring the close fit and stability of the rotating mechanism 4 and the mounting mechanism 1, and the other end of the rotating mechanism 4 is connected to the separation mechanism 2, so that the separation mechanism 2 can work in conjunction with the rotating mechanism 4 to achieve precise control during the separation process. In specific operations, when the mechanical seal needs to be disassembled, the insertion end 221 of the separation rod 22 contacts the mechanical seal and enters a locked state. Subsequently, the rotating mechanism 4 drives the separation mechanism 2 to rotate, so that the separation rod 22 rotates together with the separation ring 21, thereby expanding the mechanical seal and achieving separation from the connection.

[0063] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 , the rotating mechanism 4 comprises:

[0064] A support rod 41, fixedly connected to the mounting mechanism 1;

[0065] The buffer assembly 42 is disposed on the outer periphery of the support rod 41 , and one end of the buffer assembly 42 is threadedly connected to the support rod 41 , and the other end of the buffer assembly 42 is fixedly connected to the separation mechanism 2 .

[0066] Specifically, one end of the support rod 41 is fixedly connected to the mounting mechanism 1, ensuring the close fit and stability of the support rod 41 and the mounting mechanism 1, one end of the buffer assembly 42 is threadedly connected to the support rod 41, and the other end of the buffer assembly 42 is fixedly connected to the separation mechanism 2. This design enables the buffer assembly 42 to play a role when the separation mechanism 2 moves and provide elastic buffering. The design of the buffer assembly 42 can select different materials and shapes according to actual needs to adapt to different working environments and load requirements. Through the coordinated work of the support rod 41 and the buffer assembly 42, the separation mechanism 2 can be accurately controlled and driven. At the same time, due to the presence of the buffer assembly 42, the separation mechanism 2 can be carried out smoothly and smoothly during the movement, further reducing the potential risk of damage to the mechanical seal.

[0067] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 , the buffer assembly 42 includes:

[0068] The connecting frame 421 is threadedly connected to the outer periphery of the supporting rod 41, and the interior of the connecting frame 421 forms a guide channel;

[0069] The second elastic member 422 is disposed inside the guide channel and away from the separation mechanism 2; and

[0070] The buffer rod 423 is disposed inside the guide channel, and one end of the buffer rod 423 is fixedly connected to the second elastic member 422 , and the other end of the buffer rod 423 is fixedly connected to the separation mechanism 2 .

[0071] Specifically, a connecting frame 421 can be threadedly connected to the outer periphery of the support rod 41, so that the support rod 41 and the connecting frame 421 are firmly connected, ensuring the stability and reliability of the entire buffer assembly 42. The design of the connecting frame 421 not only takes into account the connection method with the support rod 41, but also takes into account the functionality of its internal structure. Inside the connecting frame 421, a guide channel is formed, which is a key part of the entire buffer assembly 42, allowing the buffer rod 423 to move therein while maintaining the accuracy and stability of the movement. The second elastic member 422 is located inside the guide channel and can provide elastic buffering when the separation mechanism 2 moves; and the design of the second elastic member 422 can select different materials and shapes according to actual needs to adapt to different working environments and load requirements. In addition, the elastic properties of the second elastic member 422 allow it to store energy when compressed, and use the energy to buffer and stabilize the movement of the buffer rod 423 when released. The buffer rod 423 is another key component in the buffer assembly 42. It is located inside the guide channel, and its two ends are fixedly connected to the second elastic member 422 and the separation mechanism 2, respectively, to ensure that energy can be effectively transmitted and dispersed during the movement of the separation mechanism 2, thereby avoiding damage that may be caused by impact. This design allows the buffer rod 423 to absorb and release energy through the elastic deformation of the second elastic member 422 when the separation mechanism 2 moves, thereby achieving buffering of the movement of the separation mechanism 2.

[0072] In another embodiment of the utility model, the second elastic member 422 is a spring or an elastic sheet, which can provide good elasticity for the buffer rod 423, thereby playing a certain buffering role for the tensile effect of the buffer rod 423 on the separation ring 21, avoiding direct hard pulling and causing damage to the mechanical seal.

[0073] In the embodiments of the present invention, please refer to Figure 1 , the mounting mechanism 1 comprises:

[0074] Base 11;

[0075] A mounting plate 12 is disposed on one side of the base 11, and a separation ring 21 is rotatably disposed on the mounting plate 12; and

[0076] The lifting member 13 has one end connected to the base 11 and the other end connected to the mounting plate 12 .

[0077] Specifically, the mounting mechanism 1 includes a base 11, a mounting plate 12 and a lifting member 13, wherein the lifting member 13 may be a hydraulic cylinder or a pneumatic cylinder, or a combination of a belt or a chain, as long as it can drive the mounting plate 12 to move up and down, thereby adjusting the height of the separation ring 21. Optionally, a fixing rod may be slidably sleeved on the mounting plate 12, and the fixing rod may be limited by tightening bolts, that is, the height of the separation ring 21 may be changed by adjusting the length of the support rod 41.

[0078] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
