Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically a shell-and-tube condenser with an adjustable pipe installation structure. Background Technology

[0002] A condenser is an important component in a refrigeration system and is a type of heat exchanger. Its main function is to convert gas or vapor into liquid and quickly transfer the heat in the tubes to the air near the tubes. The working principle of a shell-and-tube condenser is mainly based on the principle of heat exchange, which transfers the heat of hot gas or vapor to the cooling medium, thereby cooling it and condensing it into a liquid.

[0003] A search revealed Chinese patent CN 217585442 U, which discloses a double-baffle shell-and-tube condenser, comprising: a shell with a heat medium inlet and outlet; two tube boxes located at both ends of the shell, with the cold medium inlet and outlet distributed on the same tube box or on two separate tube boxes; and a tube bundle including a tube sheet, multiple heat exchange tubes, and multiple baffles. The tube sheet is located at both ends of the shell and connected to the tube boxes, and the multiple heat exchange tubes pass through the baffles, with the tube sheet connecting the two tube boxes. The multiple baffles include intermediate baffles and side baffles arranged alternately along the transverse direction of the shell. The intermediate baffles are distributed longitudinally along the middle portion of the shell, and the side baffles are arranged in pairs along the longitudinal direction of the shell on both sides of the middle portion. This design results in a compact product structure, reducing heat exchange tube vibration caused by large baffle spacing, and improving product reliability and service life.

[0004] The aforementioned double-baffle shell-and-tube condenser reduces the vibration of heat exchange tubes caused by the large spacing between baffles through the improvement of the built-in baffle structure. However, the medium inlet and outlet pipes of this condenser are fixed structures. During the rigid connection with the external medium pipes, there may be situations where the pipes are too short or too long, resulting in mismatch installation. It is necessary to install an intermediate connector, which is time-consuming and labor-intensive, thus affecting the assembly efficiency of the condenser.

[0005] Therefore, a shell-and-tube condenser with an adjustable pipe installation structure is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a shell-and-tube condenser with an adjustable pipe installation structure. A first U-shaped pipe and a second U-shaped pipe, connected via a second rotary joint, are respectively connected to a first joint bend and a second joint bend through the cooperation of the first and third rotary joints. One end of the first joint bend is connected to the inner shell of the condenser body, and the second joint bend is connected to an external liquid output device through one end connector. This allows the relative distance between the second joint bend and the first joint bend to be changed within a certain range by horizontally displacing the second rotary joint, replacing the need for external intermediate joints due to excessively long or short pipes. This improves equipment assembly efficiency, saves time and effort, and facilitates use and maintenance.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a shell-and-tube condenser with adjustable pipe installation structure, including a condenser body, a first connector bend connected to the outer wall of the condenser body, a first rotary joint connected to one end of the first connector bend, a first U-shaped tube connected to one end of the first rotary joint, a second rotary joint connected to one end of the first U-shaped tube, a second U-shaped tube connected to one end of the second rotary joint, a third rotary joint connected to one end of the third rotary joint, and a second connector bend connected to one end of the third rotary joint.

[0008] The outer wall of the second rotary joint is fixedly connected to a guide sleeve by a bracket. A guide rod slides through the inside of the guide sleeve. A sliding circular plate is fixedly connected to one end of the guide rod. A support rail is slidably fitted on the outer wall of the sliding circular plate. The support rail and the outer wall of the condenser body are fixedly connected by bolts.

[0009] Preferably, a U-shaped limiting frame is slidably installed above the outer wall of the supporting track, and a through hole is provided at the top center of the U-shaped limiting frame, the inner wall of the through hole being slidably connected to the outer wall of the guide rod.

[0010] Preferably, a spring is fitted on the outer wall of the guide rod, and the spring is located between the adjacent side walls of the U-shaped limiting frame and the guide sleeve.

[0011] Preferably, the bottom surfaces at both ends of the U-shaped limiting frame are provided with limiting teeth, which can mesh with the teeth on the top surface of the supporting track.

[0012] Preferably, a limit ring is fixed to the outer wall of the second joint bend.

[0013] Preferably, the outer wall of the limiting ring is fitted with an annular sleeve, and the side wall of the annular sleeve is fixedly connected to a sleeve support.

[0014] Preferably, a sleeve is vertically fixed to the bottom surface of the sleeve support, and one end of the sleeve is vertically fixed to the top surface of one end of the support track.

[0015] The beneficial effects of this utility model are:

[0016] The first U-shaped pipe and the second U-shaped pipe, connected by the second rotary joint, are respectively connected to the first joint bend and the second joint bend with the cooperation of the first rotary joint and the third rotary joint. One end of the first joint bend is connected to the inner shell of the condenser body, and the second joint bend is connected to the external liquid output device through its end connector. This allows the relative distance between the second joint bend and the first joint bend to be changed within a certain range by horizontal displacement of the second rotary joint, so as to replace the situation where the pipe is too long or too short and an external transfer joint is required. This improves the assembly efficiency of the equipment, saves time and effort, and is convenient to use and maintain. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 4 This utility model provides a shell-and-tube condenser with an adjustable pipe installation structure, including a condenser body 1. A first connector bend 11 is connected to the outer wall of the condenser body 1. One end of the first connector bend 11 is connected to a first rotary joint 12. One end of the first rotary joint 12 is connected to a first U-shaped tube 2. One end of the first U-shaped tube 2 is connected to a second rotary joint 3. One end of the second rotary joint 3 is connected to a second U-shaped tube 4. One end of the second U-shaped tube 4 is connected to a third rotary joint 41. One end of the third rotary joint 41 is connected to a second connector bend 5. The second connector bend 5 is connected to an external liquid delivery pipe, and its other end is connected to the third rotary joint 41. This achieves connection with the second U-shaped tube 4 while simultaneously allowing the third rotary joint 41 to rotate. The structural features allow for relative rotation between the second connector bend 5 and the second U-shaped tube 4 without affecting each other. One end of the second U-shaped tube 4 is connected to the first U-shaped tube 2 via the second rotary joint 3, while the first U-shaped tube 2 is connected to the first connector bend 11 with the cooperation of the first rotary joint 12. The first connector bend 11 is connected to the pipe inside the condenser body 1. Similarly, the relative distance between the second connector bend 5 and the first connector bend 11 can be controlled within a certain range by relative rotation of the first connector bend 11, the first U-shaped tube 2, the second U-shaped tube 4, and the second connector bend 5, adapting to changes in the relative distance between the access pipe and the condenser body 1. This ensures the connection between the condenser body 1 and the external output end without the need for an intermediate connector.

[0027] like Figure 1 and Figure 3As shown, the outer wall of the second rotary joint 3 is fixedly connected to a guide sleeve 31 by a bracket. A guide rod 6 slides through the inside of the guide sleeve 31. A sliding circular plate 61 is fixedly connected to one end of the guide rod 6. A support rail 7 is slidably fitted on the outer wall of the sliding circular plate 61. The support rail 7 and the outer wall of the condenser body 1 are fixedly connected by bolts. The support rail 7, which is fixed to the outer wall of the condenser body 1, installs the guide rod 6 through the mutual cooperation between its top rail and the sliding circular plate 61. The guide rod 6 slides through the outer guide sleeve 31 of the second rotary joint 3. This changes the relative angle between the first U-shaped tube 2 and the second U-shaped tube 4 during the process of pushing the guide rod 6, thereby changing the distance between the second joint bend 5 and the first joint bend 11.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a U-shaped limiting frame 8 is slidably installed on the upper part of the outer wall of the support rail 7. A through hole 81 is opened at the center of the top of the U-shaped limiting frame 8. The inner wall of the through hole 81 is slidably connected to the outer wall of the guide rod 6. A spring 82 is fitted on the outer wall of the guide rod 6. The spring 82 is located between the adjacent side walls of the U-shaped limiting frame 8 and the guide sleeve 31. Limiting teeth 83 are provided on the bottom surfaces of both ends of the U-shaped limiting frame 8. The limiting teeth 83 can mesh with the teeth on the top surface of the support rail 7. The U-shaped limiting frame 8, which is fitted between the support rail 7 and the guide rod 6 through the through hole 81, has a downward elastic force under the elastic force provided by the spring 82. At this time, the limiting teeth 83 mesh with the teeth on the top surface of the support rail 7. At this time, the relative position of the guide rod 6 and the second rotary joint 3 is limited, thereby limiting the relative angle between the first U-shaped tube 2 and the second U-shaped tube 4.

[0029] like Figure 1 and Figure 4 As shown, a limiting ring 51 is fixed to the outer wall of the second connector bend 5. An annular sleeve 9 is fitted on the outer wall of the limiting ring 51. A sleeve support 91 is fixed to the side wall of the annular sleeve 9. A sleeve 92 is vertically fixed to the bottom surface of the sleeve support 91. One end of the sleeve 92 is vertically fixed to the top surface of one end of the support rail 7. The sleeve 92, which is vertically installed on the top surface of the support rail 7, is fixed to the annular sleeve 9 fitted on the outer wall of the limiting ring 51 through the sleeve support 91 at one end. This allows the second connector bend 5 to change its relative position in the longitudinal direction as the sleeve 92 expands or contracts, thus limiting the position of the second connector bend 5.

[0030] The working principle of this utility model:

[0031] The second connector bend 5 is connected to the external liquid delivery pipeline, and its other end is connected to the third rotary joint 41 to achieve connection with the second U-shaped pipe 4. At the same time, the rotary connection structure of the third rotary joint 41 allows the second connector bend 5 and the second U-shaped pipe 4 to rotate relative to each other without affecting each other. One end of the second U-shaped pipe 4 is connected to the first U-shaped pipe 2 through the second rotary joint 3, and the first U-shaped pipe 2 is connected to the first connector bend 11 with the cooperation of the first rotary joint 12. The first connector bend 11 is connected to the pipeline inside the condenser body 1. Similarly, the distance between the second connector bend 5 and the first connector bend 11 can be controlled within a certain range by the relative rotation of the first connector bend 11, the first U-shaped pipe 2, the second U-shaped pipe 4 and the second connector bend 5, so as to adapt to the change of the relative distance between the access pipeline and the condenser body 1. Without the addition of an intermediate joint, the connection between the condenser body 1 and the external output end is ensured.

[0032] The support rail 7, fixed to the outer wall of the condenser body 1, installs the guide rod 6 through the cooperation between its top rail and the sliding circular plate 61. The guide rod 6 slides through the outer guide sleeve 31 of the second rotary joint 3, which changes the relative angle between the first U-shaped tube 2 and the second U-shaped tube 4 during the pushing of the guide rod 6, thereby changing the relative distance between the second joint bend 5 and the first joint bend 11. The U-shaped limiting bracket 8, which is fitted between the support rail 7 and the guide rod 6 through the through hole 81, has a downward elastic force under the elastic force provided by the spring 82. At this time, the limiting teeth 83 and the teeth on the top surface of the support rail 7 mesh with each other, and the relative position of the guide rod 6 and the second rotary joint 3 is limited, thus limiting the relative angle between the first U-shaped tube 2 and the second U-shaped tube 4. The sleeve 92, which is vertically installed on the top surface of the support rail 7, is fixed to the annular sleeve 9 fitted on the outer wall of the limiting ring 51 through one end of its sleeve bracket 91. This allows the second joint bend 5 to change its relative position in the longitudinal direction as the sleeve 92 extends and retracts.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
