Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, specifically to a plate heat exchanger nozzle assembly structure. Background Technology

[0002] A plate heat exchanger is a highly efficient heat exchange device, mainly composed of a series of corrugated metal plates separated by gaskets to form fluid channels. During operation, two fluids at different temperatures flow in opposite directions within the channels between adjacent plates. Utilizing the excellent thermal conductivity of the metal plates, heat is efficiently transferred between the fluids.

[0003] According to the plate heat exchanger body and heat exchange tube disclosed in announcement number CN218034590U, a water exchange tube is fixedly installed at both the inlet and outlet of the plate heat exchanger body. A fixing pipe is welded to one end of the heat exchange tube near the plate heat exchanger, and the fixing pipe extends into the water exchange tube. A first connecting plate is fixedly installed at the other end of the water exchange tube away from the plate heat exchanger body.

[0004] While the plate heat exchanger body and heat exchange tubes allow for easy assembly and disassembly during use, the bolt-mounted installation method is cumbersome and not always secure, thus requiring improvements to the device. Utility Model Content

[0005] The purpose of this utility model is to provide a plate heat exchanger nozzle assembly structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate heat exchanger nozzle assembly structure, including a support plate, an adjustment mechanism fixedly connected to the right end of the support plate, and a locking mechanism provided on the surface of the adjustment mechanism;

[0007] The adjustment mechanism includes a rod, which is fixedly connected to the inside of the support plate. A horizontal bar is fixedly connected to the right end of the rod. An L-shaped seat is provided at the bottom of the horizontal bar. An adjustment screw is provided inside the L-shaped seat. An L-shaped plate is rotatably connected to the right end of the adjustment screw.

[0008] Preferably, the L-shaped seat has a threaded hole inside, and the surface of the adjusting screw is threadedly connected to the inside of the threaded hole, which facilitates installation using the adjusting screw.

[0009] Preferably, a support hole is formed inside the left end of the support plate, and the surface of the insertion rod is fixedly connected to the support hole.

[0010] Preferably, the locking mechanism includes a movable plate, which is slidably connected to the surface of the horizontal bar. Springs are fixedly connected to the front and rear sides of the movable plate, and a vertical bar is fixedly connected to one end of each spring. T-shaped rods are slidably connected to the interior of both ends of the vertical bar. One end of each T-shaped rod is fixedly connected to the surface of the movable plate, and locking rods are fixedly connected to the front and rear sides of the movable plate near the middle.

[0011] Preferably, a perforation is formed inside the vertical bar, and the surface of the T-shaped rod is slidably connected to the perforation, so that the T-shaped rod can be inserted into the perforation and slid.

[0012] Preferably, a rectangular hole is formed on the surface of the movable plate, and the surface of the horizontal bar is slidably connected to the inside of the rectangular hole.

[0013] Preferably, the surface of the crossbar has a positioning inner hole, and the surface of the locking rod matches the inside of the positioning hole, so that the locking rod can be inserted into the positioning hole.

[0014] Compared with the prior art, this utility model provides a plate heat exchanger nozzle assembly structure, which has the following advantages:

[0015] 1. The plate heat exchanger's pipe assembly structure, through its adjustable mechanism, ensures that when the L-shaped plate moves to the predetermined position, it will be firmly locked onto the vertical bar, thereby further stabilizing the position of the vertical bar. This step is actually a secondary locking of the locking rod, ensuring that even if it is subjected to vibration or external force during use, the locking rod will not easily detach from the horizontal bar and the movable plate, thus effectively preventing the movable plate from moving or loosening, thereby improving the stability of the installation.

[0016] 2. The plate heat exchanger's nozzle assembly structure, through a locking mechanism, features a locking rod designed to tightly engage with the movable plate and horizontal bars. When the vertical bars slide to the predetermined position, the locking rod accurately engages with these two components, achieving initial fixation of the movable plate. This process not only ensures the stability of the movable plate but also allows for flexible adjustment of the spacing between multiple movable plates as needed, thus meeting diverse installation requirements and avoiding the need for bolt installation and disassembly.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Combination Figures 2 to 4 A plate heat exchanger nozzle assembly structure includes a support plate 1, an adjustment mechanism 2 is fixedly connected to the right end of the support plate 1, and a locking mechanism 3 is provided on the surface of the adjustment mechanism 2.

[0028] The adjustment mechanism 2 includes a rod 21, which is fixedly connected to the inside of the support plate 1. A horizontal bar 22 is fixedly connected to the right end of the rod 21. An L-shaped seat 23 is provided at the bottom of the horizontal bar 22. An adjustment screw 24 is provided inside the L-shaped seat 23. An L-shaped plate 25 is rotatably connected to the right end of the adjustment screw 24. A threaded hole is opened inside the L-shaped seat 23. The surface of the adjustment screw 24 is threadedly connected to the inside of the threaded hole.

[0029] Furthermore, a support hole is opened inside the left end of the support plate 1, and the surface of the insertion rod 21 is fixedly connected to the support hole. This ensures that even if the rod is subjected to vibration or external force during use, the locking rod 35 will not easily detach from the crossbar 22 and the movable plate 31, thereby effectively avoiding the possible movement or loosening of the movable plate 31 and improving the stability of the installation.

[0030] Example 2

[0031] See Figure 1-4 Furthermore, based on Embodiment 1, the locking mechanism 3 further includes a movable plate 31, which is slidably connected to the surface of the horizontal bar 22. Springs 32 are fixedly connected to the front and rear sides of the movable plate 31, and a vertical bar 34 is fixedly connected to one end of the springs 32. T-shaped rods 33 are slidably connected to the interior of both ends of the vertical bar 34. One end of the T-shaped rod 33 is fixedly connected to the surface of the movable plate 31. Locking rods 35 are fixedly connected to the front and rear sides of the movable plate 31 near the middle. A through hole is opened inside the vertical bar 34, and the surface of the T-shaped rod 33 is slidably connected to the through hole.

[0032] Furthermore, a rectangular hole is formed on the surface of the movable plate 31, and the surface of the crossbar 22 is slidably connected to the inside of the rectangular hole. A positioning inner hole is formed on the surface of the crossbar 22, and the surface of the locking rod 35 matches the inside of the positioning hole. The locking rod 35 then accurately engages with these two components, achieving initial fixation of the movable plate 31. This process not only ensures the stability of the movable plate 31 but also allows for flexible adjustment of the spacing between multiple movable plates 31 according to actual needs when installing them, thereby meeting diverse installation requirements and avoiding the need for bolt installation and disassembly operations.

[0033] In actual operation, when this device is used, precise and secure component connections are crucial during pipe installation. When multiple movable plates 31 need to be passed through the surface of the crossbar 22 to construct pipe supports or connection structures, a sophisticated fixing mechanism is designed to ensure that these movable plates 31 are securely installed in the intended positions.

[0034] First, the operator inserts the movable plates 31 one by one through the pre-set holes on the horizontal bars 22. This step requires extremely high precision to ensure that the movable plates 31 pass through smoothly and in accurate positions. After insertion, the crucial fixing process begins. At this point, the vertical bar 34 plays a vital role in the system. Utilizing the elastic properties of the spring 32, it slides in a restricted manner on the surface of the T-shaped bar 33. This design allows the vertical bar 34 to flexibly adjust its position while maintaining a certain tension.

[0035] As the vertical bar 34 slides, the locking rod 35 at its end also moves. The locking rod 35 is designed to fit tightly into the movable plate 31 and the horizontal bar 22. When the vertical bar 34 slides to the predetermined position, the locking rod 35 accurately engages with these two components, achieving initial fixation of the movable plate 31. This process not only ensures the stability of the movable plate 31 but also allows for flexible adjustment of the spacing between multiple movable plates 31 according to actual needs, thereby meeting diverse installation requirements.

[0036] However, the initial fixation by the clamp 35 alone is far from sufficient. To ensure the long-term stability and safety of the piping system during use, further reinforcement is required. This is where the adjusting screw 24 comes in handy. By rotating the adjusting screw 24, the operator utilizes its threaded connection with the L-shaped seat 23 to smoothly move the L-shaped plate 25 on the top mating surface of the L-shaped seat 23.

[0037] The movement of the L-shaped plate 25 is a precise and powerful process, designed to fit closely to the surface of the vertical bar 34 during movement. When the L-shaped plate 25 reaches its predetermined position, it locks firmly onto the vertical bar 34, further stabilizing its position. This step is essentially a secondary locking of the locking lever 35, ensuring that even under vibration or external force during use, the locking lever 35 will not easily detach from the horizontal bar 22 and the movable plate 31, effectively preventing any movement or loosening of the movable plate 31.

[0038] Through such a sophisticated and complex fixing mechanism, the movable plate 31 during the pipeline installation process can not only be securely installed on the crossbar 22, but also be flexibly adjusted according to actual needs, while ensuring the long-term stability and safety of the entire pipeline system.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
