Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a plate heat exchanger. Background Art

[0002] A plate heat exchanger is an efficient heat exchange device. Its design and structural characteristics make it an ideal choice for liquid-liquid and liquid-vapor heat exchange in a variety of industrial and commercial applications. It is a device that uses a series of metal plates to achieve efficient heat energy exchange. With its high heat exchange efficiency, compact structure, easy maintainability and flexibility, it is widely used in many fields such as heating, ventilation and air conditioning, chemical industry, food processing, energy recovery, etc.

[0003] After retrieval, the text of the patent number "CN220750891U" mentions that "the utility model relates to a plate heat exchanger, including multiple groups of heat exchange plates. A convenient disassembly and assembly mechanism is arranged at the outer ends of the multiple groups of heat exchange plates. The convenient disassembly and assembly mechanism includes a base, a fixing plate, a first slider, a movable plate, two groups of rotating motors, two groups of threaded rods, two groups of guide rods, multiple groups of second sliders and multiple groups of hinge rods. With the design of the convenient disassembly and assembly mechanism, when disassembling the plate heat exchanger, two groups of rotating motors can be operated to drive the two groups of threaded rods to rotate synchronously. Thus, under the threaded cooperation of the two groups of threaded rods and the movable plate, the first slider and the movable plate are driven to slide to the left simultaneously. During the continuous leftward sliding of the movable plate, through the connection of multiple groups of hinge rods, multiple groups of second sliders and heat exchange plates will be driven to slide to the left in sequence from left to right until the movable plate moves to the leftmost side and the output of the two groups of rotating motors stops. At this time, multiple groups of heat exchange plates have been disassembled respectively and the intervals are equal". When in use, it can disassemble, assemble and clean the plate heat exchanger more conveniently and efficiently, effectively improving the disassembly, assembly and cleaning efficiency of the plate heat exchanger. However, the connection parts between the heat exchanger and the external pipeline system, such as flanges, nozzles, etc., may leak or become loose due to vibration, and long-term operation or frequent start-stop will cause the clamping bolts to become loose and the pressing force to be uneven, affecting the sealing performance between the plates, thus resulting in the instability of the overall structure of the equipment.

[0004] Therefore, we provide a plate heat exchanger to solve the above problems. Summary of the Utility Model

[0005] This application provides a plate heat exchanger, which solves the problems of leakage or loosening caused by vibration, and the clamping bolts becoming loose and the pressing force being uneven due to long-term operation or frequent start-stop.

[0006] This application provides a plate heat exchanger, including an outer frame and a vibration damping and loosening prevention mechanism. A base is installed at the bottom end of the outer frame, and a vibration damping and loosening prevention mechanism is arranged on one side of the base;

[0007] The vibration-damping and anti-loosening mechanism includes a vibration-damping component installed inside the base, a fixing component is arranged on the outside of the outer frame, a connecting component is installed on the surface of the fixing component, an anti-loosening component is arranged on one side of the fixing component, and a plug-in component is installed on the outside of the connecting component.

[0008] Preferably, the vibration reduction assembly comprises a base installed inside the base, an elastic member is installed on the inner side of the base, and a spring is installed on the inner side of the elastic member.

[0009] Preferably, the fixing assembly comprises a bolt installed on the inner side of the outer frame, a fixing ring is installed on the outer side of the bolt, and a nut is threadedly connected to the surface of the bolt.

[0010] Preferably, the connection assembly comprises a first connection member mounted on the surface of the fixing ring, and a second connection member is disposed on one side of the first connection member.

[0011] Preferably, the anti-loosening assembly comprises an upper locking washer arranged on one side of the nut, and a lower locking washer is engaged on the other side of the upper locking washer.

[0012] Preferably, the plug-in assembly comprises an elastic plug-in installed on the outside of the first connector, and a control button is installed on the top of the second connector.

[0013] Preferably, a working component is installed on one side of the outer frame, and the working component includes a heat exchanger body installed on one side of the outer frame, and a connecting port is installed on the outer side of the heat exchanger body.

[0014] It can be seen from the above technical scheme that the present application provides a plate heat exchanger. When in use, first install the upper locking washer and the lower locking washer on the bolt, then install the nut on the bolt, and then put the fixing ring under the nut. When the base is vibrated, the vibration force is first transmitted to the base, and then the vibration force further acts on the elastic member installed in the base. The elastic member is made of rubber because of its excellent elasticity and damping characteristics, and can start to play a role at the moment of force. They can effectively absorb and dissipate part of the vibration energy. At the same time, the spring also begins to intervene in the vibration response process. When the vibration force continues to be transmitted to the spring, the spring can quickly undergo moderate expansion and contraction deformation by virtue of its unique elastic deformation ability, and dynamically counteract the vibration force through its own elastic force, thereby effectively offsetting part of the vibration force, thereby alleviating and reducing the impact of vibration on the overall equipment, and using the upper locking washer and the lower locking washer, using their special structure to automatically increase the nut preload during vibration to prevent the threaded connection from loosening, and complete the use of the plate heat exchanger.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the setting of the vibration reduction and anti-loosening mechanism, when the base is vibrated, the vibration force is first transmitted to the base, and then the vibration force further acts on the elastic parts installed in the base. The elastic parts are made of rubber. Due to their excellent elasticity and damping characteristics, they can start to play a role at the moment of force. They can effectively absorb and dissipate part of the vibration energy. At the same time, the spring also begins to intervene in the vibration response process. When the vibration force continues to be transmitted to the spring, the spring can quickly undergo moderate expansion and contraction deformation with its unique elastic deformation ability, and dynamically counteract the vibration force through its own elastic force, thereby effectively offsetting part of the vibration force, thereby alleviating and reducing the impact of vibration on the overall equipment. In addition, the upper locking washer and the lower locking washer are used, and their special structure is used to automatically increase the nut preload during vibration, ensuring that the nut can maintain a relatively stable working state in a vibration environment;

[0017] 2. Through the setting of the plug-in component, the elastic plug-in is accurately embedded in the slot reserved in the second connecting piece, so that the elastic plug-in and the nut form an effective locking linkage relationship. Through the unique structure and force characteristics of the plug-in, a continuous holding force is applied to the nut to ensure that it is firmly fixed in the initial state. When the equipment is in working state and encounters external vibration, the vibration energy will try to act on the nut through various channels to try to loosen it. At this moment, the vibration energy is transmitted to the elastic element under the elastic plug-in. With its inherent elastic properties and buffering capacity, the element quickly absorbs and effectively disperses part of the vibration force, thereby ensuring that the nut remains stable in a vibration environment and eliminating the risk of accidental loosening due to vibration.

[0018] To summarize, the present application effectively offsets part of the vibration force by setting up a vibration-damping and anti-loosening mechanism, ensures that the nut can maintain a relatively stable working state in a vibration environment, and eliminates the risk of accidental loosening of the nut due to vibration.
