Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of heat exchange device technology, and more specifically, to a closed-loop metal corrugated plate heat exchange structure. Background Technology
[0002] In modern industrial production, efficient heat exchange technology plays an irreplaceable role in the stable operation and improved production efficiency of many key equipment. Taking the aluminum ore slurry ball mill as an example, as the core equipment for processing aluminum ore into alumina, the mill releases a large amount of heat during the grinding process due to the intense collisions and friction between the grinding media (such as steel balls) and the material, as well as the crushing of the material. This causes the operating temperature of the ball mill to rise sharply. If heat dissipation cannot be timely and effective, it will lead to serious problems such as short circuits, excessive wear of equipment components, and deterioration of lubrication, thus posing a significant threat to the safety and continuity of production.
[0003] To address the heat dissipation challenges of ball mills, plate heat exchangers are widely used in the cooling of lubricating oil. However, existing plate heat exchangers face significant challenges in cleaning and maintenance. Due to their inadequate heat exchange structure design, the disassembly process of the heat exchange plates is extremely complex, often requiring substantial manpower, resources, and time. This not only makes thorough cleaning difficult, leading to the gradual accumulation of dirt on the heat exchange plate surface, further reducing heat exchange efficiency, increasing equipment energy consumption and production costs, but also makes frequent disassembly operations prone to damaging the equipment and shortening its service life. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a circulating closed-loop metal corrugated plate heat exchange structure, which solves the technical problem that the heat exchange plates are difficult to disassemble and clean when cleaning plate heat exchange devices in the prior art.
[0005] According to one aspect, at least one embodiment of the present disclosure provides a closed-loop metal corrugated plate heat exchanger structure, comprising:
[0006] Frame;
[0007] A sliding plate is vertically slidably mounted on the frame; the sliding plate has a plurality of grooves, which are arranged in a divergent pattern.
[0008] A heat exchange plate, wherein there are several heat exchange plates, and the heat exchange plates are slidably disposed on the frame and arranged sequentially along the thickness direction of the heat exchange plates; each heat exchange plate has a first protrusion.
[0009] The first protruding sidewall slides against the inner wall of the groove; after the sliding plate slides vertically, it drives several heat exchange plates to slide synchronously, so that the several heat exchange plates abut against each other or release from contact.
[0010] For example, in a closed-loop metal corrugated plate heat exchange structure provided in at least one embodiment of this disclosure, the first protrusion extends out of the groove, and further includes:
[0011] A locking element is disposed on the first protrusion, and one side of the locking element abuts against the sliding plate.
[0012] For example, in at least one embodiment of this disclosure, a closed-loop metal corrugated plate heat exchanger structure further includes:
[0013] A pressing plate is slidably disposed within the frame body; after the heat exchange plates abut against each other, the pressing plate slides to press the heat exchange plates together.
[0014] For example, in a closed-loop metal corrugated plate heat exchange structure provided in at least one embodiment of this disclosure, the clamping plate has a through groove; after the clamping plate slides close to the heat exchange plate, one end of the sliding plate passes through the through groove.
[0015] For example, in a circulating closed-loop metal corrugated plate heat exchanger structure provided in at least one embodiment of this disclosure, the frame has a mounting beam, the clamping plate is slidably disposed on the mounting beam, and further includes:
[0016] A roller is rotatably mounted on the pressure plate; the pressure plate slides on the mounting beam via the roller.
[0017] For example, in a closed-loop metal corrugated plate heat exchange structure provided in at least one embodiment of this disclosure, there are two sliding plates, which are arranged vertically symmetrically, and the structure further includes:
[0018] A bidirectional lead screw is rotatably mounted on the frame, and two sliding plates are threadedly connected to both ends of the bidirectional lead screw, respectively.
[0019] A rotation drive component is mounted on the frame and is used to drive the bidirectional lead screw to rotate.
[0020] For example, in a closed-loop metal corrugated plate heat exchanger structure provided in at least one embodiment of this disclosure, the frame has a mounting portion and further includes:
[0021] A push rod is slidably disposed on the mounting part. After the push rod slides close to the clamping plate, it pushes the clamping plate close to the heat exchange plate.
[0022] For example, in a circulating closed-loop metal corrugated plate heat exchange structure provided in at least one embodiment of this disclosure, the clamping plate has a sleeve on the side away from the heat exchange plate, and the inner wall of the sleeve has an annular groove; the top rod has an annular protrusion at the end near the clamping plate.
[0023] The annular protrusion is rotatably disposed within the annular groove; after the push rod slides, it drives the pressing plate to move closer to or away from the heat exchange plate.
[0024] For example, in a circulating closed-loop metal corrugated plate heat exchange structure provided in at least one embodiment of this disclosure, the top rod is threadedly connected to the mounting part.
[0025] For example, in at least one embodiment of this disclosure, a closed-loop metal corrugated plate heat exchanger structure further includes:
[0026] A handle is provided at the end of the top rod away from the annular protrusion.
[0027] The beneficial effects of the embodiments disclosed herein are as follows:
[0028] In this disclosure, during heat exchange, the heat exchange plates abut against each other to form an effective heat exchange channel. When cleaning and maintenance of the heat exchange plates are required, the operator manually or through a drive device slides the sliding plate vertically. Due to the sliding contact between the first protrusion and the groove, the vertical sliding of the sliding plate will cause several heat exchange plates to slide synchronously, releasing them from contact and facilitating individual cleaning of each heat exchange plate.
[0029] The advantage is that this structure solves the problem of difficult disassembly of heat exchange plates during cleaning in existing plate heat exchangers. Operators do not need complicated disassembly operations; they can easily separate and combine the heat exchange plates by simply controlling the vertical sliding plate. This improves cleaning convenience, reduces cleaning costs and time consumption, and reduces the risk of equipment damage caused by frequent disassembly. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Therefore, they should not be construed as limitations on this disclosure.
[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0042] like Figures 1-4 As shown, a closed-loop metal corrugated plate heat exchange structure according to an embodiment of the present disclosure is illustrated, including a frame 1; a sliding plate 2 is vertically slidably disposed on the frame 1; the sliding plate 2 has a plurality of sliding grooves 201, which are radiating outwards; a plurality of heat exchange plates 3 are slidably disposed on the frame 1 and arranged sequentially along the thickness direction of the heat exchange plates 3; the heat exchange plates 3 have a first protrusion 301; the sidewall of the first protrusion 301 slides against the inner wall of the sliding groove 201; after the sliding plate 2 slides vertically, it drives the plurality of heat exchange plates 3 to slide synchronously, so that the plurality of heat exchange plates 3 abut against each other or release from contact.
[0043] For example, such as Figure 1 and Figure 4 As shown, to address the technical problem of difficulty in disassembling and cleaning heat exchange plates in existing plate heat exchangers, a closed-loop metal corrugated plate heat exchange structure was designed. During heat exchange, the heat exchange plates 3 abut against each other to form an effective heat exchange channel. When cleaning and maintenance of the heat exchange plates 3 is required, the operator manually or via a drive device slides the sliding plate 2 vertically. Due to the sliding contact between the first protrusion 301 and the groove 201, the vertical sliding of the sliding plate 2 causes several heat exchange plates 3 to slide synchronously, releasing their contact and facilitating individual cleaning of each heat exchange plate 3.
[0044] The advantage is that this structure solves the problem of difficult disassembly of heat exchange plates 3 during cleaning in existing plate heat exchangers. Operators do not need complicated disassembly operations; they can easily separate and combine heat exchange plates 3 by simply controlling the vertical sliding of the sliding plate 2. This improves the convenience of cleaning, reduces cleaning costs and time consumption, and reduces the risk of equipment damage caused by frequent disassembly.
[0045] In some examples, the first protrusion 301 extends out of the slide groove 201 and also includes a locking member 4, which is disposed on the first protrusion 301 and one side of the locking member 4 abuts against the slide plate 2.
[0046] For example, such as Figure 1 and Figure 4As shown, the first protrusion 301 of the heat exchange plate 3 is designed to extend out of the sliding groove 201. The locking element 4 is a nut, with external threads machined on the protruding part of the protrusion, and the nut is screwed onto the external threads. After the heat exchange plates 3 are installed and abut against each other, the nut is tightened so that one side of it abuts tightly against the sliding plate 2.
[0047] The advantage is that the locking element 4 enhances the connection stability between the heat exchange plate 3 and the sliding plate 2 without affecting the separation operation of the heat exchange plate 3.
[0048] In some examples, a clamping plate 5 is also included, which is slidably disposed within the frame 1; after several heat exchange plates 3 abut against each other, the clamping plate 5 slides to clamp the several heat exchange plates 3.
[0049] For example, such as Figure 1 and Figure 4 As shown, a special guide rail is provided inside the frame 1, and the clamping plate 5 is slidably installed inside the frame 1 through the cooperation of the guide rail. After several heat exchange plates 3 abut against each other under the action of the sliding plate 2, the clamping plate 5 can slide along the guide rail to approach the heat exchange plates 3.
[0050] Specifically, after the heat exchange plates 3 abut against each other to form a heat exchange channel, the clamping plate 5 is slid along the guide rail toward the heat exchange plates 3 by a manual or electric drive device until it is in tight contact with the heat exchange plates 3. During cleaning and maintenance, the clamping plate 5 is first slid away from the heat exchange plates 3, and then the heat exchange plates 3 are separated.
[0051] The advantage is that the clamping plate 5 further enhances the sealing between the heat exchange plates 3. During heat exchange, it ensures that the heat exchange fluid does not leak, thus improving heat exchange efficiency. During cleaning, the sliding design of the clamping plate 5 does not affect the disassembly of the heat exchange plates 3, ensuring that the cleaning work can be carried out smoothly.
[0052] In some examples, the clamping plate 5 has a through groove 501; after the clamping plate 5 slides close to the heat exchange plate 3, one end of the sliding plate 2 passes through the through groove 501.
[0053] For example, such as Figure 1 and Figure 4 As shown, the clamping plate 5 has a through groove 501, which is designed to allow one end of the sliding plate 2 to pass through smoothly. When the clamping plate 5 slides close to the heat exchange plate 3, one end of the sliding plate 2 passes through the through groove 501.
[0054] Specifically, after the heat exchange plates 3 abut against each other, the clamping plate 5 slides towards the heat exchange plates 3. During the sliding process, one end of the sliding plate 2 gradually enters the through groove 501, and finally the clamping plate 5 and the heat exchange plates 3 are tightly abutted together, while the sliding plate 2 passes through the through groove 501. During cleaning, the clamping plate 5 is first slid away from the heat exchange plates 3, so that the sliding plate 2 is removed from the through groove 501, and then the heat exchange plates 3 are separated.
[0055] The advantage is that the through groove 501 design ensures that the pressing plate 5 is not obstructed by the sliding plate 2 when it approaches the heat exchange plate 3, guaranteeing that the pressing plate 5 can smoothly and tightly abut against the heat exchange plate 3. At the same time, the through groove 501 also restricts the position of the sliding plate during heat exchange, preventing the sliding plate 2 from sliding vertically. This optimizes the overall layout and working performance of the heat exchange structure. The disassembly of the heat exchange plate 3 is also not affected during cleaning.
[0056] In some examples, the frame 1 has a mounting beam 101, a clamping plate 5 is slidably disposed on the mounting beam 101, and also includes a roller 6, which is rotatably disposed on the clamping plate 5; the clamping plate 5 slides on the mounting beam 101 via the roller 6.
[0057] For example, such as Figure 1 and Figure 4 As shown, the upper surface of the mounting beam 101 of the frame 1 is machined with a smooth guide rail, and the top of the clamping plate 5 is rotatably mounted with a roller 6 via a bearing. The roller 6 is suspended on the mounting beam 101 and cooperates with the guide rail on the mounting beam 101, so that the clamping plate 5 can slide on the mounting beam 101 via the roller 6.
[0058] The advantage is that the roller 6 setting greatly reduces the friction during the sliding process of the pressure plate 5, making the pressure plate 5 slide more smoothly and flexibly.
[0059] In some examples, there are two sliding plates 2, which are arranged vertically symmetrically. The system also includes a bidirectional lead screw 7, which is rotatably mounted on the frame 1. The two sliding plates 2 are threaded to both ends of the bidirectional lead screw 7. A rotation drive 8 is mounted on the frame 1 and is used to drive the bidirectional lead screw 7 to rotate.
[0060] For example, such as Figure 1 and Figure 4 As shown, a bidirectional lead screw 7 is rotatably mounted on the frame 1 via a bearing seat. Both ends of the bidirectional lead screw 7 are machined with threads of opposite directions but the same pitch. Two sliding plates 2 are each equipped with a nut seat that matches the threads at both ends of the bidirectional lead screw 7, achieving threaded connection with the ends of the bidirectional lead screw 7. The rotation drive component 8 is a motor, mounted on the frame 1, and the motor output shaft is connected to one end of the bidirectional lead screw 7 via a coupling.
[0061] Specifically, when it is necessary for the heat exchange plates 3 to come into contact or separate, the rotation drive 8 is activated, and the motor drives the bidirectional lead screw 7 to rotate. Since the threads at both ends of the bidirectional lead screw 7 rotate in opposite directions, the two sliding plates 2 will move synchronously towards or away from each other under the drive of the bidirectional lead screw 7. When the two sliding plates 2 move towards each other, they cause the heat exchange plates 3 to come into contact; when they move away from each other, they cause the heat exchange plates 3 to separate.
[0062] The advantage is that the bidirectional lead screw 7 and the rotary drive component 8 work together to achieve synchronous movement of the two sliding plates 2, and more accurately control the contact and separation of the heat exchange plate 3.
[0063] In some examples, the frame 1 has a mounting part 102 and also includes a push rod 9, which is slidably disposed on the mounting part 102. After the push rod 9 slides close to the pressure plate 5, it pushes the pressure plate 5 close to the heat exchange plate 3.
[0064] For example, such as Figure 2 As shown, the mounting part 102 of the frame 1 is machined with guide holes, and the push rod 9 is slidably mounted on the mounting part 102 through the guide holes. When it is necessary to push the pressure plate 5 closer to the heat exchange plate 3, the push rod 9 slides towards the pressure plate 5 under the guidance of the guide holes.
[0065] The advantage is that the push rod 9 provides a reliable driving force for the sliding of the pressure plate 5. By controlling the sliding of the push rod 9, the clamping force between the pressure plate 5 and the heat exchange plate 3 can be accurately adjusted, ensuring the sealing and stability of the heat exchange structure.
[0066] In some examples, the clamping plate 5 has a sleeve 502 on the side away from the heat exchange plate 3, and the inner wall of the sleeve 502 has an annular groove 503; the push rod 9 has an annular protrusion 901 at the end near the clamping plate 5; the annular protrusion 901 is rotatably disposed in the annular groove 503; after the push rod 9 slides, it drives the clamping plate 5 to move closer to or away from the heat exchange plate 3.
[0067] For example, such as Figure 3 As shown, a sleeve 502 is welded to the side of the clamping plate 5 away from the heat exchange plate 3. The sleeve 502 is a split type for easy installation. An annular groove 503 is machined on the inner wall of the sleeve 502. An annular protrusion 901 is formed on the end of the push rod 9 near the clamping plate 5. The annular protrusion 901 matches the size of the annular groove 503 and can rotate freely within the annular groove 503.
[0068] Specifically, as the push rod 9 continues to slide, it drives the pressure plate 5 to move closer to the heat exchange plate 3; when the push rod 9 slides in the opposite direction, the annular protrusion 901 is in the annular groove 503, which prevents the push rod 9 from disengaging from the pressure plate 5, thus driving the pressure plate 5 away from the heat exchange plate 3.
[0069] The advantage is that the rotational engagement between the annular protrusion 901 and the annular groove 503 makes the push rod 9 push the clamping plate 5 more flexibly. This can compensate for possible installation errors and movement deviations between the push rod 9 and the clamping plate 5, ensuring that the push rod 9 can push the clamping plate 5 smoothly and accurately, thereby improving the reliability and stability of the entire heat exchange structure.
[0070] In some examples, the push rod 9 is threaded to the mounting part 102.
[0071] For example, such as Figure 3 As shown, the mounting part 102 has an internally threaded hole, and the outer surface of the push rod 9 has an external thread that matches the internally threaded hole. The push rod 9 is connected to the mounting part 102 by a thread. The operator can control the sliding of the push rod 9 on the mounting part 102 by rotating it.
[0072] Specifically, when it is necessary to push the clamping plate 5 closer to the heat exchange plate 3, the operator rotates the push rod 9 clockwise. Due to the threaded connection, the push rod 9 slides towards the clamping plate 5 on the mounting part 102. When it is necessary to move the clamping plate 5 away from the heat exchange plate 3, the operator rotates the push rod 9 counterclockwise, and the push rod 9 slides in the opposite direction.
[0073] The advantage is that the threaded connection allows for good controllability and self-locking of the sliding of the push rod 9. The operator can precisely control the clamping force between the pressure plate 5 and the heat exchange plate 3 by rotating the push rod 9. Once the appropriate clamping state is achieved, the threaded connection prevents the push rod 9 from sliding on its own, ensuring a stable clamping state.
[0074] In some examples, a handle 10 is also included, which is located at the end of the top rod 9 away from the annular protrusion 901.
[0075] For example, such as Figure 2 As shown, a handle 10 is welded or bolted to the end of the top rod 9 away from the annular protrusion 901. The handle 10 is in a shape that is easy to grip, such as round or oval.
[0076] Specifically, the operator rotates the push rod 9 by holding the handle 10. When it is necessary to push the clamping plate 5 closer to the heat exchange plate 3, hold the handle 10 and rotate the push rod 9 clockwise; when it is necessary to move the clamping plate 5 away from the heat exchange plate 3, hold the handle 10 and rotate the push rod 9 counterclockwise.
[0077] The advantage is that the handle 10 provides the operator with a convenient point of leverage. With the handle 10, the operator can rotate the top rod 9 more easily and effortlessly, improving the convenience and comfort of operation.
