Thin rectangular channels are formed between the various plates, and heat exchange is carried out through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid and liquid-gas heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. However, existing devices have certain drawbacks. For example, the announcement No. CN221882275U records a plate heat exchanger for utilizing waste heat from chemical wastewater, including a plate heat exchanger body, the plate heat exchanger body including a body, heat exchange fins and a water inlet, the heat exchange fins are provided with a plurality of them, and the plurality of heat exchange fins are movably connected to the opposite side of the body, the water inlet is provided with two, the left sides of the two water inlets are connected to the right side of the body, and a measuring component is provided on the front side of the body;

[0003] The above-mentioned device cooperates with the measuring component to adjust the threaded component, but uses a threaded column or screw in conjunction with a nut to fix the two plate surfaces, and clamps and fixes the heat exchange plate between the plate surfaces. This structure causes the nut to rotate too many times and have a long stroke when the device is disassembled, affecting the disassembly speed of the device. Utility Model Content

[0008] Furthermore, the upper surface of the base is provided with mounting holes near the four corners.

[0009] Furthermore, the inner surface of the hinged seat is hinged with retaining rods, and the number of the retaining rods is four.

[0010] Furthermore, the downward pressure module includes a downward pressure frame, a limiting half ring, a limiting ring, a rotating rod, a flip frame and a bolt. The downward pressure frame is slidably connected to the outer surface of the measuring column, the limiting half ring is fixedly connected to the outer surface of the downward pressure frame near the measuring column position, the limiting ring is fixedly connected to the outer surface of the downward pressure frame near the retaining rod position, the rotating rod is rotatably connected to the inner surface of the downward pressure frame, the flip frame is fixedly connected to the outer surface of the rotating rod, and the outer surface of the flip frame is threadedly connected with a bolt.

[0013] Furthermore, flange connecting pipes are fixedly connected to the upper surface of the movable plate near the four corners.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. When disassembling, manually rotate the bolt to separate the bolt and the contact plate, and then cooperate with the rotating rod to flip the flip frame to release the fixation between the pressing module and the vertical plate. The limiting half ring and the measuring column are slidably connected, and the limiting ring and the retaining rod are slidably connected. Therefore, the pressing module can be directly manually removed upwards to release the fixation of the retaining rod and the movable plate to the pressing module, making it easier to disassemble the movable plate.

During disassembly, the number of turns of the threaded component is reduced, making the device disassembly faster.

[0016] 2. After the downward pressure of the downward pressure module on the movable plate is lost, the universal ball can be used to slide along the slide groove to separate the movable plate and the heat exchange plate, so that the upper end of the heat exchange plate loses its fixation. The heat exchange plate can be manually removed along the measuring column later, which facilitates the disassembly of the heat exchange plate and further completes the disassembly of the device.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 In an embodiment of the present utility model, a detachable plate heat exchanger includes a base 2, a connecting plate 202 being fixedly connected to the upper surface of the base 2, a fixing plate 1 being fixedly connected to the upper surface of the fixing plate 1, two vertical plates 5 being fixedly connected to the upper surface of the fixing plate 1, two measuring columns 605 being fixedly connected to the upper surface of the fixing plate 1, a heat exchange fin 7 being slidably connected to the inner surface of the vertical plate 5, and a hinged seat 3 being hingedly connected to the lower surface of the fixing plate 1;

[0024] The outer surface of the vertical plate 5 is slidably connected to the movable plate 6 , and the outer surface of the measuring column 605 is slidably connected to the pressing module 4 .

[0025] Specifically, when disassembling, use a tool to rotate the two bolts 406, and one end of the bolt 406 can be separated from the contact plate 501 under the push of the thread, and then the flip frame 405 can be manually rotated outward to make the pressing module 4 lose the fixation of the vertical plate 5, and the pressing module 4 can be slid upward along the measuring column 605 and the retaining rod 301. After removing the pressing module 4, the retaining rod 301 loses the fixation, and the movable plate 6 loses the downward force provided by the pressing module 4, and the movable plate 6 can be manually removed upward along the vertical plate 5, so that the upper end of the heat exchange plate 7 loses the external fixation, and the heat exchange plate 7 can be further disassembled. In addition, the present device is fixed with bolts 406, which is different from the traditional screw and nut fixation. The number of turns of the threaded assembly during disassembly is less, making the device faster to disassemble, and the measuring column 605 can measure the height of the heat exchange plate 7, which is convenient for installing the appropriate number of heat exchange plates 7 according to actual usage requirements. Example 1

[0026] like Figure 1-4 As shown, mounting holes 201 are provided on the upper surface of the base 2 near the four corners, a retaining rod 301 is hinged on the inner surface of the hinged seat 3, and the number of retaining rods 301 is four. A contact plate 501 is provided on the outer surface of the vertical plate 5, and a sliding groove 502 is provided on the outer surface of the vertical plate 5. The upper surface of the movable plate 6 is fixedly connected to flange connecting pipes 601 near the four corners.

[0027] In this embodiment, the device can be installed on the working surface in conjunction with the mounting hole 201 and the threaded assembly. The retaining rod 301 can share the force applied by the downward pressure module 4 to the measuring column 605 to maintain the stability of the device. The slide groove 502 is used to limit the rolling direction of the universal ball 603, and the flange connecting pipe 601 is used to connect to the external medium circulation pipeline. Example 2

[0028] On the basis of the first embodiment, in order to make up for the problem in the first embodiment that it is inconvenient to quickly disassemble the device.

[0029] like Figure 1-4 As shown, the pressing module 4 includes a pressing frame 401, a limiting half ring 402, a limiting ring 403, a rotating rod 404, a flip frame 405 and a bolt 406. The pressing frame 401 is slidingly connected to the outer surface of the measuring column 605, the limiting half ring 402 is fixedly connected to the outer surface of the pressing frame 401 near the measuring column 605, the limiting ring 403 is fixedly connected to the outer surface of the pressing frame 401 near the retaining rod 301, the rotating rod 404 is rotatably connected to the inner surface of the pressing frame 401, the flip frame 405 is fixedly connected to the outer surface of the rotating rod 404, and the outer surface of the flip frame 405 is threadedly connected with the bolt 406.

[0030] In this embodiment, when disassembling, the bolt 406 is manually rotated to separate the bolt 406 and the contact plate 501, and then the turning rod 404 is cooperated to flip the flip frame 405, so that the fixation between the pressing module 4 and the vertical plate 5 can be lost, the limiting half ring 402 and the measuring column 605 are slidably connected, and the limiting ring 403 and the retaining rod 301 are slidably connected. Therefore, the pressing module 4 can be directly manually removed upwards to make the retaining rod 301 and the movable plate 6 lose the fixation of the pressing module 4, which is convenient for disassembling the movable plate 6. Moreover, this fixation using the bolt 406 is different from the traditional screw and nut fixation. The number of turns of the threaded component during disassembly is fewer, which makes the device faster to disassemble.

[0031] The upper surface of the movable plate 6 is fixedly connected to the mounting plates 602 near the edges on both sides, and the outer surface of the mounting plates 602 is rotatably connected to the universal balls 603. The upper surface of the movable plate 6 is provided with limiting grooves 604, and the universal balls 603 are rollingly connected to the slide grooves 502.

[0032] In this embodiment, after the downward pressure of the downward pressure module 4 on the movable plate 6 is lost, the universal ball 603 can be cooperated to slide along the slide groove 502 to separate the movable plate 6 and the heat exchange plate 7, so that the upper end of the heat exchange plate 7 loses its fixation. Later, the heat exchange plate 7 can be manually taken out along the measuring column 605, which facilitates the later disassembly of the heat exchange plate 7 and further completes the disassembly of the device.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
