Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a condenser structure for liquid oxygen production. Background Technology

[0002] Due to its unique physicochemical properties, the application of liquid oxygen in aerospace, medical, and industrial fields relies heavily on efficient condensers to achieve the phase transition from gaseous to liquid state. This phase transition process involves complex thermodynamic transformations and materials science challenges. The core of this process lies in precisely controlling the temperature, pressure, and heat transfer efficiency through the condenser to overcome the technical difficulties brought about by the strong oxidizing properties, extremely low temperature, and high expansion ratio of liquid oxygen.

[0003] However, in some existing condensers, the sealing ring is prone to significant friction with its inner wall during installation. This friction not only causes the sealing ring to get stuck and difficult to install, reducing installation efficiency, but may also damage the sealing ring, affecting its sealing performance and service life.

[0004] In addition, some existing condensers also present significant problems when disassembling the sealing ring. As the equipment is used for a long time, the sealing ring will fit tightly against the inner wall of the condenser, which will greatly increase the friction between the sealing ring and the installation part, thus increasing the difficulty of disassembly. In this case, the staff often need to use a lot of force to remove the sealing ring, which not only increases the workload and labor intensity of the staff, but may also damage the sealing ring during the disassembly process. Utility Model Content

[0005] The purpose of this invention is to provide a condenser structure for liquid oxygen production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a condenser structure for liquid oxygen production, comprising a condensation mechanism body and a flange fixedly connected to one side of its surface, and further comprising:

[0007] A rounded groove is formed on the inner wall of the flange to facilitate the installation of the sealing ring. A mounting bracket is fixedly connected to the inner wall of the flange. The inner cavity of the mounting bracket is provided with several compression mechanisms to facilitate the removal of the sealing ring. Sliding grooves are formed on the inner walls of the mounting bracket, the flange and the condensation mechanism body. A connecting bracket is provided on one side of the compression mechanism, and a connecting plate is fixed on one side of the connecting bracket.

[0008] A limiting mechanism is installed in the inner cavity of the connecting plate to limit the compression mechanism. The surface of the condensation mechanism body is provided with an installation groove, and a limiting block is fixed to the inner wall of the installation groove.

[0009] Preferably, the compression mechanism includes a spring fixedly connected to the inner wall of the mounting frame, one end of the spring being fixedly connected to a sliding column, and one side of the sliding column being fixedly connected to a connecting block.

[0010] Preferably, the limiting mechanism includes a positioning groove formed on the surface of the connecting plate, a positioning block slidably connected to the inner wall of the positioning groove, and a handle slidably connected to the surface of the connecting plate.

[0011] Preferably, the cross-sectional shape of the positioning groove and the positioning block is T-shaped.

[0012] Preferably, the rounded corner groove is designed with a circular arc structure.

[0013] Preferably, the inner wall of the connecting frame is slidably connected to the inner wall of the condensation mechanism body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the design of rounded corner grooves, facilitates the installation of the sealing ring, reducing the likelihood of jamming during installation due to excessive friction. This improves installation efficiency, reduces the risk of damage to the sealing ring during installation, and ensures its sealing performance and service life. The compression and limiting mechanisms facilitate easy disassembly of the sealing ring, reducing the likelihood of it sticking to the inner wall of the condenser after long-term use and becoming difficult to remove. This reduces the workload and labor intensity of operators and minimizes damage to the sealing ring during disassembly, solving the problem of difficult sealing ring installation and removal in existing condensers.

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4 As shown, a condenser structure for liquid oxygen production includes a condensing mechanism body 1, which is composed of heat exchange tubes and other structures for easy operation. A flange 2 is fixedly connected to one side surface of the condensing mechanism body 1. The flange 2 is a key component for connecting the condensing mechanism body 1 to other equipment or pipelines. Several mounting holes are provided on the surface of the flange 2 for easy connection. The inner cavity of the flange 2 is used to install a sealing ring. Two rounded corner grooves 3 are provided on the inner wall of the flange 2. The rounded corner grooves 3 are arc-shaped designs. Under the action of the rounded corner grooves 3, When the sealing ring is installed, the rounded groove wall of the rounded corner groove 3 provides a smooth guide for the sealing ring, allowing it to slide smoothly into the predetermined installation position along the arc surface of the rounded corner groove 3. This reduces friction and jamming between the sealing ring and the inner wall of the flange 2 during installation, lowers the risk of damage to the sealing ring due to forced installation, and thus improves the installation efficiency of the sealing ring. The inner wall of the flange 2 is fixedly connected to the mounting bracket 4, the surface of the mounting bracket 4 is in contact with the sealing ring, and the inner cavity of the mounting bracket 4 is equipped with several compression mechanisms 5. The mounting bracket 4, flange 2, and condensation mechanism body are connected. The inner wall of flange 1 is provided with sliding grooves 6. The sliding grooves 6 cooperate with the compression mechanism 5. Under this action, when the sealing ring needs to be removed from the inner cavity of flange 2, the compression mechanism 5 can apply a uniform force to the sealing ring, causing the sealing ring to detach from the surface of the mounting bracket 4, thus making it easier for the staff to remove it. This greatly facilitates the subsequent replacement of the sealing ring or equipment maintenance, reduces the problem of the sealing ring being difficult to remove from the mounting bracket 4 and flange 2 due to long-term use, and reduces the labor intensity of the staff. A connecting bracket 7 is provided on one side of the compression mechanism 5. The inner wall is slidably connected to the inner wall of the condensing mechanism body 1. A connecting plate 8 is fixed on one side of the connecting frame 7. A limiting mechanism 9 is provided in the inner cavity of the connecting plate 8. An installation groove 10 is opened on the surface of the condensing mechanism body 1. A limiting block 11 is fixed on the inner wall of the installation groove 10. The limiting block 11 works in conjunction with the limiting mechanism 9. Under this action, the operator can pull the limiting mechanism 9 to drive the compression mechanism 5 to move. The limiting block 11 can limit the limiting mechanism 9, thereby reducing the possibility of accidental movement of the compression mechanism 5 during use and ensuring the stability of the condenser during use.

[0023] The compression mechanism 5 includes a spring 51 fixedly connected to the inner wall of the mounting bracket 4. One end of the spring 51 is fixedly connected to a sliding post 52, the surface of which is slidably connected to the inner wall of the mounting bracket 4. A connecting block 53 is fixedly connected to one side of the sliding post 52, the surface of which is slidably connected to the inner wall of the mounting bracket 4 and the inner wall of the sliding groove 6. One end of the connecting block 53 is fixedly connected to the surface of the connecting bracket 7. Under this action, when the sealing ring needs to be installed, the operator operates the limiting mechanism 9 to drive the connecting plate 8, the connecting bracket 7, the connecting block 53, and the sliding post 52 to compress the spring. 51. The sliding column 52 is fully inserted into the inner cavity of the mounting bracket 4, which facilitates the installation of the sealing ring by the operator. When the sealing ring needs to be removed, the operator operates the limiting mechanism 9 to release the mutual obstruction effect with the limiting block 11. Under the elastic force of the spring 51, the sliding column 52 returns to its original position, thereby applying a uniform force to the sealing ring and causing the sealing ring to detach from the surface of the mounting bracket 4, making it easier for the operator to remove it. This reduces the difficulty in removing the sealing ring from the mounting bracket 4 and flange 2 due to long-term use, and reduces the labor intensity of the operator.

[0024] The limiting mechanism 9 includes a positioning groove 91 formed on the surface of the connecting plate 8. A positioning block 92 is slidably connected to the inner wall of the positioning groove 91. Both the positioning groove 91 and the positioning block 92 have a T-shaped cross-section. A handle 93 is slidably connected to the surface of the connecting plate 8. The bottom of the handle 93 is fixedly connected to the surface of the positioning block 92. Under this action, when the sliding column 52 needs to be fully inserted into the inner cavity of the mounting bracket 4 to install the sealing ring, the operator pulls the handle 93 to move it. After moving it to the appropriate position, the operator moves the handle 93 to one side, so that the handle 93 and the limiting block 11 block each other, thereby limiting the sliding column 52 so that it will not affect the normal use of the sealing ring. When it is necessary to remove the sealing ring, the operator moves the handle 93 to the other side to release the mutual blocking effect between the handle 93 and the limiting block 11. Then, under the elastic force of the spring 51, the sealing ring can be removed. This effectively reduces the risk of accidental movement of the sliding column 52 during use and ensures the reliability of the condenser during use.

[0025] It is worth noting that the technical features such as the condensation mechanism body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, the rounded groove 3 on the inner wall of flange 2 provides a smooth guide for the installation of the sealing ring, reducing friction and jamming, lowering the risk of damage to the sealing ring, and improving installation efficiency. When the sealing ring needs to be installed, the operator pulls handle 93 to move connecting plate 8, connecting bracket 7, connecting block 53, and sliding column 52, so that sliding column 52 is fully inserted into the inner cavity of mounting bracket 4. At this time, the handle 93 is moved to one side, so that handle 93 and limit block 11 block each other, thereby limiting sliding column 52 and ensuring that sliding column 52 will not affect the normal use of sealing ring. When it is necessary to remove... When removing the sealing ring, the operator moves the handle 93 to the other side to release the mutual obstruction between the handle 93 and the limiting block 11. Under the elastic force of the spring 51, the sliding column 52 returns to its original position, thereby applying a uniform force to the sealing ring and causing it to detach from the surface of the mounting bracket 4. This makes it easier for the operator to remove the sealing ring, effectively reducing the difficulty in removing the sealing ring from its installation position due to factors such as tight fit and component aging during long-term use of the sealing ring, mounting bracket 4, and flange 2. This reduces the workload and labor intensity of the operator when disassembling the sealing ring.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
