[0001] This utility model relates to the field of plate heat exchanger technology, specifically a plate heat exchanger that is easy to disassemble. Background Technology

[0002] In industrial production and many fields involving heat exchange, plate heat exchangers are widely used in industries such as chemical, pharmaceutical, HVAC, and food and beverage due to their high heat exchange efficiency, compact structure, and flexible applicability. However, in traditional plate heat exchangers, the disassembly and replacement of plates are usually cumbersome. The plates are typically tightly clamped in a fixed frame, and disassembly often requires specialized tools, consuming a significant amount of time and labor. This complex disassembly process affects the efficiency of equipment maintenance, leading to prolonged downtime and consequently impacting the continuity of the entire production process.

[0003] Therefore, those skilled in the art have provided a method for easily disassembling plate heat exchangers to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a plate heat exchanger that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plate heat exchanger that is easy to disassemble includes a front end plate. Upper guide rods are fixedly connected to both upper corners of the front end plate, and lower guide rods are fixedly connected to both lower corners of the front end plate. A front fixing block is fixedly connected to the center of the lower end of the front end plate. A reciprocating screw is rotatably connected to the rear end of the front fixing block, and a support column is rotatably connected to the other end of the reciprocating screw. The rear ends of the upper and lower guide rods extend to a position flush with the support column. A rear end plate is slidably connected to the upper and lower guide rods. A rear fixing block is fixedly connected to the center of the lower end of the rear end plate, and the rear fixing block is threadedly connected to the reciprocating screw.

[0007] As a further embodiment of this utility model: a motor is fixedly mounted on the front end surface of the front fixing block, the output shaft of the motor is fixedly connected to the reciprocating lead screw through a coupling, and the motor is electrically connected to an external power source.

[0008] As a further embodiment of this utility model: a plurality of plates are movably arranged between the front end plate and the rear end plate, the plates are erected on the upper end of the lower guide rod, and the top of the plates abuts against the upper guide rod.

[0009] As a further embodiment of this utility model: the rear end surface of the front end plate is provided with threaded hole one and threaded hole two near the two side edges, and the two sides of the rear end plate are provided with light hole one and light hole two near the edges, the light hole one and threaded hole one are located on the same side and are corresponding in position, and the light hole two and threaded hole two are located on the same side and are corresponding in position.

[0010] As a further embodiment of this utility model: the first threaded hole is internally threaded to a first limiting rod, the other end of the first limiting rod extends through the first light hole to the rear of the rear end plate; the second threaded hole is internally threaded to a second limiting rod, the other end of the second limiting rod extends through the second light hole to the rear of the rear end plate.

[0011] As a further improvement of this utility model: the length of the second limiting rod is the same as that of the reciprocating lead screw, and the length of the first limiting rod is shorter than that of the second limiting rod.

[0012] As a further improvement of this utility model: the lower end of the front plate is fixedly connected with support legs near the corners on both sides, and the lower end of the rear plate is fixedly installed with casters near the corners on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Convenient and efficient disassembly and installation: The reciprocating screw is driven by a motor to rotate. Combined with the sliding connection between the rear end plate and the upper and lower guide rods, as well as the auxiliary movement design of the caster wheels, the rear end plate can move quickly and smoothly relative to the front end plate. The heat exchanger can be easily opened in a short time, which facilitates the removal of the plates. During installation, the plates can be quickly assembled by simply reversing the operation, which greatly shortens the equipment maintenance time and improves production efficiency.

[0015] Flexible plate positioning: Utilizing the combination of threaded holes and smooth holes, along with the setting of limit rod one and limit rod two, the plates can be reliably positioned during heat exchanger operation, ensuring they remain stably in the heat exchange working position and preventing displacement that could affect heat exchange efficiency. Furthermore, during disassembly, simply turning the limit rods allows for precise release of the plate's constraint, facilitating removal from a specific direction. This operation is simple and unlikely to damage the plates. Additionally, the positions of limit rod one and limit rod two can be flexibly adjusted according to the actual conditions of the site, changing the plate disassembly orientation and enabling the equipment to better adapt to different installation environments and maintenance needs.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1-3 This embodiment provides a plate heat exchanger that is easy to disassemble, including a front plate 1. Upper guide rods 2 are fixedly connected to both upper corners of the front plate 1, and lower guide rods 3 are fixedly connected to both lower corners of the front plate 1. A front fixing block 12 is fixedly connected to the center of the lower end of the front plate 1. A reciprocating screw 14 is rotatably connected to the rear end of the front fixing block 12. A support column 15 is rotatably connected to the other end of the reciprocating screw 14. The rear ends of the upper guide rods 2 and lower guide rods 3 extend to a position flush with the support column 15. A rear plate 4 is slidably connected to the upper guide rods 2 and lower guide rods 3. A rear fixing block 16 is fixedly connected to the center of the lower end of the rear plate 4, and the rear fixing block 16 is threadedly connected to the reciprocating screw 14.

[0023] Example 2

[0024] Reference Figure 1-3This embodiment is based on the previous embodiment, but differs in that a motor 13 is fixedly mounted on the front surface of the front fixing block 12. The output shaft of the motor 13 is fixedly connected to the reciprocating lead screw 14 via a coupling. The motor 13 is electrically connected to an external power source. Several plates 5 are movably arranged between the front plate 1 and the rear plate 4. The plates 5 stand on the upper end of the lower guide rod 3, and the top of the plates 5 abuts against the upper guide rod 2. Threaded holes 6 and 8 are respectively opened on the rear surface of the front plate 1 near the two side edges. Light holes 7 and 9 are respectively opened on the two side edges of the rear plate 4. The light holes 7 and 6 are located on the same side. On one side, and correspondingly, the second light hole 9 and the second threaded hole 8 are located on the same side and correspondingly. The first threaded hole 6 is internally threaded to a limiting rod 10. The other end of the limiting rod 10 passes through the first light hole 7 and extends to the rear of the rear end plate 4. The second threaded hole 8 is internally threaded to a limiting rod 11. The other end of the limiting rod 11 passes through the second light hole 9 and extends to the rear of the rear end plate 4. The length of the limiting rod 11 is the same as that of the reciprocating lead screw 14. The length of the limiting rod 10 is shorter than that of the limiting rod 11. The lower end of the front end plate 1 is fixedly connected to the corners on both sides with support legs 18. The lower end of the rear end plate 4 is fixedly installed with casters 17 on both sides with casters 17.

[0025] Working principle: During normal operation, the front plate 1 and the rear plate 4 are tightly fitted together by the upper guide rod 2, the lower guide rod 3, and the first and second limit rods 10 and 11, which stably clamp several plates 5 between them. At this time, the motor 13 is stopped, the reciprocating screw 14 does not rotate, and the plates 5 are arranged in an orderly manner under the limiting action. The heat exchange medium flows into and out of the channels between the plates 5 from the corresponding inlets and outlets on the front plate 1 and the rear plate 4, respectively, to achieve efficient heat exchange. When it is necessary to replace, clean, or maintain the plates 5, that is, to disassemble the plate heat exchanger. First, the motor 13 is started. The output shaft of the motor 13 drives the reciprocating screw 14 to rotate via a coupling. Since the rear fixing block 16, which is fixedly connected to the lower end of the rear end plate 4, is threadedly connected to the reciprocating screw 14, and the rear end plate 4 is simultaneously slidably connected to the upper guide rod 2 and the lower guide rod 3, and the universal wheel 17 at the lower end of the rear end plate 4 provides auxiliary support for movement, under the rotational drive of the reciprocating screw 14, the rear end plate 4 gradually moves away from the front end plate 1 along the axial direction of the upper guide rod 2 and the lower guide rod 3, and the distance between the two gradually increases, making room for the removal of the plate 5. Then, the rotation... Limiting rod 10 is unscrewed from threaded hole 6 of front plate 1, releasing the limiting constraint on plate 5 on this side. At this time, plate 5 is only held in position by limiting rod 21 on the other side. The operator can then easily remove plate 5 horizontally from the lower guide rod 3 for cleaning, maintenance, or replacement. When reinstalling plate 5 after maintenance, first align the bottom of plate 5 with the lower guide rod 3 and place it on the lower guide rod 3. Then push plate 5 horizontally until one end of plate 5 abuts against limiting rod 21, ensuring that plate 5 is in the correct installation position. Next, screw the limiting rod 10 into the threaded hole 6. The upper guide rod 2, lower guide rod 3, limiting rod 10 and limiting rod 2 11 will again securely limit the plate 5 from both sides, ensuring the stability of the plate 5 during subsequent operation. Start the motor 13 again, causing it to reverse and drive the reciprocating screw 14 to rotate in the opposite direction. The rear end plate 4 will then gradually move towards the front end plate 1 along the upper guide rod 2 and lower guide rod 3 until the rear end plate 4 returns to its initial position of tightly fitting the front end plate 1. This completes the quick installation of the plate heat exchanger, and the equipment can be put back into normal operation.
