Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a detachable enhanced heat transfer plate heat exchanger. Background Technology

[0002] A plate heat exchanger is a device that uses metal plates as heat transfer elements to transfer heat from one fluid to another. Its core feature is that it achieves efficient heat exchange through indirect heat exchange, where the two fluids do not come into direct contact but are separated and flow through the plates.

[0003] Traditional plate heat exchangers are widely used in many fields such as chemical, food, and pharmaceutical industries due to their compact structure and relatively high heat exchange efficiency. However, during long-term use, the plate surfaces are prone to scaling and clogging, which not only significantly reduces heat exchange efficiency but also increases fluid flow resistance and energy consumption. More importantly, the structural design of traditional plate heat exchangers has flaws, requiring the entire heat exchanger to be disassembled for cleaning and maintenance. This operation is cumbersome, consumes a lot of time and manpower, leads to prolonged equipment downtime, and significantly increases maintenance costs, seriously affecting production continuity and economic efficiency.

[0004] The purpose of this invention is to provide a detachable reinforced heat transfer plate heat exchanger to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a detachable enhanced heat transfer plate heat exchanger, including an upper cover, characterized in that: a clamping and fixing mechanism is provided on the upper cover, and a first clearance groove is provided on the upper cover;

[0006] The clamping and fixing mechanism includes a first spring passing through the first clearance groove. Both ends of the first spring are fixedly connected to connecting members. The connecting members include a first push plate, a connecting plate, and a second push plate. A fourth clearance groove is opened in the upper cover body. The fourth clearance groove is located below the middle section of the first clearance groove and the two are perpendicular to each other. A trapezoidal slider is provided in the fourth clearance groove. The shorter side of the trapezoidal slider points to the inside of the upper cover body. A screw is provided on the longer side of the trapezoidal slider. The screw extends outward from the upper cover body and is threadedly engaged with the upper cover body. Push rods are provided on both sides of the inclined side of the trapezoidal slider. One end of each push rod is fixedly connected to two of the first push plates.

[0007] The lower part of the upper cover is provided with T-shaped grooves located between the two first push plates and between the two second push plates, and several T-shaped sliding parts are slidably connected in each T-shaped groove.

[0008] According to the above technical solution, each of the outermost T-shaped sliding members is fixed to the connecting member. Except for the outermost T-shaped sliding members, each T-shaped sliding member has a buffer rubber pad glued to both sides. The outermost T-shaped sliding member has the buffer rubber pad glued to only one side. A heat exchange plate is clamped and connected between every two buffer rubber pads. A second clearance groove is also provided on the upper cover between the two second push plates. A second spring is inserted in the second clearance groove. The two ends of the second spring are fixedly connected to the second push plate respectively.

[0009] The outer side of the upper cover and the heat exchange plate is provided with an outer shell, and the bottom surface of the inner shell is provided with several positioning blocks. The upper section inside the outer shell is also fixedly provided with a stop block.

[0010] According to the above technical solution, the surfaces of the push rod and the trapezoidal slider are adapted to each other, and the trapezoidal slider and the push rod are in sliding cooperation.

[0011] According to the above technical solution, a third clearance groove is provided on one side of each of the two connecting members on the upper cover, and the third clearance groove is adapted to the connecting member.

[0013] According to the above technical solution, the screw is a combination of a flat cylindrical structure with a large diameter and a slender cylindrical structure with a small diameter. One end of the cylindrical structure with a large diameter is inserted into the trapezoidal slider, and a limiting ring is sleeved on the screw. The limiting ring is fixedly installed in the trapezoidal slider.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0015] (1) By setting a clamping and fixing mechanism on the upper cover body consisting of a first spring, a connecting piece, a push rod, a trapezoidal slider and a screw, the rotating screw can drive the trapezoidal slider to move back and forth. Under the sliding of the trapezoidal slider and the elastic action of the first spring, the push rod drives the connecting piece to open and close relative to the upper cover body. The heat exchange plate can be disassembled and assembled by simply operating the clamping and fixing mechanism, which greatly shortens the maintenance time and reduces the maintenance cost.

[0016] (2) When the T-shaped sliding part is driven to slide by the opening and closing of the connecting parts, the buffer rubber pad plays the role of buffering the clamping or loosening of the heat exchange plate, which can not only ensure the stable installation of the heat exchange plate, but also avoid damage to the heat exchange plate during disassembly and assembly, thus extending the service life of the heat exchange plate.

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention provides a technical solution: a detachable enhanced heat transfer plate heat exchanger, including an upper cover 1, a clamping and fixing mechanism 2 provided on the upper cover 1, and a first clearance groove 11 provided on the upper cover 1.

[0027] like Figure 2 and Figure 3As shown, the clamping and fixing mechanism 2 includes a first spring 21 passing through the first clearance groove 11. Both ends of the first spring 21 are fixedly connected to connecting members 22. The connecting member 22 includes a first push plate 221, a connecting plate 222, and a second push plate 223. A fourth clearance groove 14 is provided in the upper cover 1. The fourth clearance groove 14 is located below the middle section of the first clearance groove 11 and the two are perpendicular. A trapezoidal slider 26 is provided in the fourth clearance groove 14. The shorter side of the trapezoidal slider 26 points into the upper cover 1. A screw 27 is provided on the longer side of the trapezoidal slider 26. The screw 27 extends outward from the upper cover 1 and is threadedly engaged with the upper cover 1. Push rods 23 are provided on both sides of the inclined side of the trapezoidal slider 26. One end of each push rod 23 is fixedly connected to two of the first push plates 221.

[0028] By rotating the screw 27, the trapezoidal slider 26 is driven to move back and forth. Under the influence of the sliding of the trapezoidal slider 26, and due to the connecting action of the elastic first spring 21, the push rod 23 drives the connecting piece 22 to open and close relative to the upper cover 1.

[0029] like Figure 4 As shown, T-shaped grooves 15 are respectively provided between the two first push plates 221 and between the two second push plates 223 on the lower part of the upper cover 1. Several T-shaped sliding members 25 are slidably connected in each T-shaped groove 15. The T-shaped sliding members 25 can slide within the T-shaped groove 15.

[0030] like Figure 4 As shown, each outermost T-shaped sliding member 25 is fixed to the connecting member 22. Except for the outermost T-shaped sliding member 25, each T-shaped sliding member 25 has a buffer rubber pad 28 glued to both sides. The outermost T-shaped sliding member 25 only has the buffer rubber pad 28 glued to one side. A heat exchange plate 3 is clamped between every two buffer rubber pads 28. A second clearance groove 12 is also provided on the upper cover 1 between the two second push plates 223. A second spring 24 passes through the second clearance groove 12, and both ends of the second spring 24 are fixedly connected to the second push plate 223. The opening and closing of the connecting member 22 relative to the upper cover 1 causes the T-shaped sliding member 25 to slide within the T-shaped groove 15. Simultaneously, the buffer rubber pad 28 buffers and clamps or releases the heat exchange plate 3. The second spring 24 has the same function as the first spring 21.

[0031] like Figure 4 and Figure 5As shown, an outer shell 4 is provided on the outside of the upper cover 1 and the heat exchange plate 3. Several positioning blocks 41 are provided on the bottom surface inside the outer shell 4, and a stop block 42 is fixedly provided in the upper section inside the outer shell 4. The positioning blocks 41 are used to position and support the heat exchange plate 3 to ensure its correct installation, and the stop block 42 is used to support the installation of the upper cover 1.

[0032] like Figure 3 As shown, the surfaces of the push rod 23 and the trapezoidal slider 26 are compatible, and the trapezoidal slider 26 and the push rod 23 are in sliding engagement. When the trapezoidal slider 26 slides inward relative to the upper cover 1, it pushes the push rod 23 outward; when the trapezoidal slider 26 slides outward relative to the upper cover 1, the two push rods 23 retract towards each other under the pull of the first spring 21.

[0033] like Figure 2 As shown, a third clearance groove 13 is provided on one side of each of the two connectors 22 on the upper cover 1. The third clearance groove 13 is adapted to the connector 22. This ensures that the connector 22 is fully retracted and embedded in the upper cover 1, so that after the clamping and fixing mechanism 2 clamps the heat exchange plate 3, the upper cover 1 can be smoothly installed into the outer shell 4.

[0034] like Figure 5 As shown, the gap between any two adjacent positioning blocks 41 is adapted to the thickness of the heat exchange plate 3. The clamping and fixing mechanism 2 clamps the heat exchange plate 3 and securely installs it into the outer casing 4, with each heat exchange plate 3 inserted into the gap between two adjacent positioning blocks 41.

[0035] like Figure 6 As shown, the screw 27 combines a flat, large-diameter cylindrical structure with a slender, small-diameter cylindrical structure. One end of the large-diameter cylindrical structure of the screw 27 passes through the trapezoidal slider 26, and a limiting ring 5 is sleeved on the screw 27. The limiting ring 5 is fixedly installed in the trapezoidal slider 26 to ensure that while the screw 27 drives the trapezoidal slider 26 to move back and forth, the trapezoidal slider 26 will not rotate accordingly.

[0036] Working principle: When disassembling the heat exchange plate 3, the upper cover 1 must first be removed from the outer shell 4. At this time, the clamping and fixing mechanism 2 and the clamped heat exchange plate 3 will be detached from the outer shell 4 as a whole. In the initial state, the first spring 21 and the second spring 24 are both in a certain pre-tension state, providing a stable elastic force for the clamping and fixing mechanism 2. Subsequently, the operator rotates the screw 27. Since the screw 27 is threaded with the upper cover 1, the screw 27 will slide along its axial direction toward the center of the upper cover 1. Therefore, the axial movement of the screw 27 will drive the trapezoidal slider 26 to slide inward synchronously in the fourth clearance groove 14. The inclined side of the trapezoidal slider 26 is adapted to and slides in contact with the push rod 23. As the trapezoidal slider 26 slides inward, its inclined side will generate an outward pushing force on the push rod 23, causing the push rod 23 to move outward, and at the same time driving the first push plate 221 fixedly connected to it to move outward.

[0037] Since the connecting member 22 is composed of the first push plate 221, the connecting plate 222, and the second push plate 223, and the parts are interconnected, the second push plate 223 will also move outward, thereby causing the outermost T-shaped sliding member 25, which is fixed to the connecting member 22, to slide outward in the T-shaped groove 15. As the outermost T-shaped sliding member 25 moves, the other T-shaped sliding members 25 will also slide accordingly in the T-shaped groove 15, and the distance between adjacent T-shaped sliding members 25 gradually increases. The space between the buffer rubber pads 28 also expands. The heat exchange plate 3, which was originally clamped by the buffer rubber pads 28, gradually loses its clamping force until it disappears under the elastic relative release action of the buffer rubber pads 28. At this time, the heat exchange plate 3 can be easily removed from between the adjacent T-shaped sliding members 25, completing the disassembly operation of the heat exchange plate 3.

[0038] When it is necessary to install the heat exchange plate 3, the operation process is the reverse of the disassembly process, which will not be described in detail here.
