Description

Technical Field

[0001] This invention relates to the field of stacked plate heat exchanger technology, specifically to a stacked plate heat exchanger with a single-plate design. Background Technology

[0002] With the rapid development of industries such as chemical, petroleum, food, and power, the demand for customized heat exchangers is increasing. The requirements for the size, number of fluid channels, and port positions of heat exchangers change frequently in different scenarios. The plates of traditional stacked plate heat exchangers are often fixed as a whole by means of through beams, with small intervals between the plates. If a single plate is damaged, all plates must be removed for repair and replacement, which not only makes maintenance difficult but also leads to extended equipment downtime and affects production efficiency.

[0003] Patent CN218764763U discloses a flat-plate heat exchanger, comprising a fixed plate, heat exchange plates, a pressing plate, and a support plate. The pressing plate is movably mounted on four guide columns. Multiple heat exchange plates are tightly pressed between the fixed plate and the pressing plate by locking screws and nuts. Four connecting flanges are welded to the left side surface of the fixed plate. The rightmost end of the four guide columns is fixed to the support plate. The right side surface of the support plate is recessed to the left to form four mating grooves. Compared with the prior art, this device has the following advantages: by replacing the original rear support column with a single support plate, and by setting a matching connecting flange on the support plate... The device features a docking slot, with two connecting flanges that can be inserted and fixed to the support plate, connecting two stacked plate heat exchangers into a whole. This improves the stability of the plate heat exchangers during transportation, thus facilitating their transport. The structure is simple and easy to manufacture. However, while this device improves the stability of the plate heat exchangers during transportation, it is prone to misalignment when fixing the stacked plates, making it difficult to guarantee the overall stability of the equipment. Furthermore, it is difficult to guarantee that the equipment will not leak during operation, reducing the equipment's replacement effect. Therefore, a stacked plate heat exchanger with a single-plate design is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stacked plate heat exchanger with a single plate design, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a stacked plate heat exchanger with a single plate design, including a connecting frame, a mounting plate fixedly connected to the front side of the connecting frame, an air inlet pipe fixedly connected to the front side of the mounting plate, an air outlet pipe fixedly connected to the front side of the mounting plate, an air outlet mechanism for indirect air outlet provided on the inner wall of the air outlet pipe, a movable plate slidably connected to the inner wall of the connecting frame, a roller rotatably connected to the inner wall of the movable plate, stacked plates slidably connected to the inner wall of the connecting frame, bolts slidably connected to the inner wall of the movable plate, an anti-corrosion mechanism for preventing equipment corrosion provided on the front side of the movable plate, and a top connection of the connecting frame. The device features an elastic telescopic plate with a roller rotatably connected to its inner wall. The circumferential surface of the roller contacts the circumferential surface of the roller. When exchanging heat in factories or commercial settings, the device can be installed inside. At this time, the mounting plate is installed on the front side of the connecting frame. The roller will dampen the movable plate through the contraction end of the elastic telescopic plate, allowing the movable plate to more accurately position and press the stacked plates, preventing loosening during operation and ensuring accurate positioning of the plates in the up, down, left, and right directions. This avoids misalignment caused by insufficient rigidity of the positioning holes or human error, prevents sealing leaks caused by positioning deformation after disassembly or maintenance, improves overall sealing reliability, and enhances the heat exchange efficiency of the device. The connecting frame includes bolts, and a long plate is slidably connected to the circumferential surface of the bolts via springs. A hinge rod is hinged to the inner wall of the long plate, and a positioning plate is hinged to the inner wall of the hinge rod. A pressure cylinder is rotatably connected to the inner wall of the positioning plate. The rear side of the mounting plate contacts the circumferential surface of the pressure cylinder, the front side of the movable plate contacts the circumferential surface of the pressure cylinder, the positioning plate contacts both sides of the stacked plates, the front side of the movable plate contacts the rear side of the stacked plates, and the rear side of the mounting plate contacts the front side of the stacked plates. When the stacked plates are retracted and fixed, the movable plate moves to drive the positioning plate to squeeze the stacked plates, ensuring that the sealing gaskets between each plate are subjected to uniform force, thereby preventing local leakage or premature gasket failure. It can withstand the pressure difference between the media and maintain the stable position of the plates during operation, significantly reducing plate displacement or loosening caused by vibration. During disassembly, the plates can be quickly removed simply by loosening the clamping studs, shortening maintenance downtime and reducing maintenance costs.

[0006] Preferably, the anti-corrosion mechanism includes an energy block, the top of the connecting frame is fixedly connected to the bottom of the energy block, the output end of the energy block is fixedly connected to a power line, an L-shaped plate is fixedly connected to the side of the power line away from the energy block, an electric rod is slidably connected to the inner wall of the L-shaped plate by a spring, a round wheel is installed on the side of the L-shaped plate near the connecting frame, guide grooves are opened on both sides of the connecting frame, and the inner wall of the guide groove contacts the circumferential surface of the round wheel. When the equipment is working, the stacked plates inside the equipment will corrode. In order to improve the service life of the equipment, the movement of the movable plate will drive the electric rod to output current to prevent corrosion of the stacked plates. A weak current is introduced to make the plate potential lower than the corrosion potential, preventing corrosion reaction from occurring. By adjusting the current density, the protection intensity can be adjusted in real time according to the corrosiveness of the medium, temperature, flow rate and other working conditions to ensure that sufficient protection can be provided under different operating conditions, reduce the safety risks such as leakage or explosion caused by corrosion, protect the safety of personnel and equipment on the production site, and improve the working efficiency of the equipment. The anti-corrosion mechanism includes a connecting rod, which is fixedly connected to the circumferential surface of the air intake pipe. The connecting rod is slidably connected to an anti-leakage plate via a spring. The rear side of the L-shaped plate is fixedly connected to the front side of the movable plate. The inner wall of the anti-leakage plate is in contact with the circumferential surface of the air intake pipe. During hot gas replacement, the air pipe is fixedly connected to the air intake pipe, and the anti-leakage plate will move closer to the connecting rod via the spring, thereby sealing the connection of the air intake pipe. It can generate a self-tightening effect under pressure, significantly increasing the contact pressure of the sealing surface, reducing the probability of leakage, maintaining the complete contact of the heat exchange surface, reducing thermal resistance, and improving the overall heat transfer coefficient.

[0007] Preferably, the air outlet mechanism includes a positioning block, and the two sides of the anti-leakage plate are fixedly connected to the positioning block. The inner wall of the positioning block is rotatably connected to a buckle by a torsion spring. The two sides of the anti-leakage plate are fixedly connected to a locking block. When the anti-leakage plate is sealed, the top anti-leakage plate drives the buckle to cooperate with the locking block for fixation, preventing the seal from shifting or deforming during operation, thereby greatly reducing the risk of leakage. This allows the seal to be quickly inserted or removed, significantly shortening the time for maintenance, cleaning or replacement, and reducing downtime costs. The venting mechanism includes a piston plate. The inner wall of the vent pipe is rotatably connected to the piston plate via a torsion spring. An L-shaped rod is hinged to the inner wall of the piston plate and slidably connected to the inner wall of the vent pipe. A helical rod is fixedly connected to the inner wall of the L-shaped rod, and the circumferential surface of the helical rod is slidably connected to the inner wall of the vent pipe. A circular plate is rotatably connected to the inner wall of the vent pipe, and the inner wall of the circular plate contacts the circumferential surface of the helical rod. The inner wall of the latch contacts the latching block, and the latch contacts both sides of the leak-proof plate. The circumferential surface of the helical rod has a... The inner wall of the circular plate is fixedly connected to a movable block, which is movably connected to the inner wall of the threaded groove. After heat exchange, the internal gas will be discharged through the vent pipe. At this time, the internal gas pressure will push the piston plate to rotate. The rotation of the piston plate will drive the circular plate to rotate and open the vent hole, thereby achieving the effect of automatic venting, maintaining pressure balance, preventing equipment damage caused by pressure fluctuations, realizing the self-regulation of system pressure, ensuring operational safety, improving energy efficiency and equipment life, and significantly reducing manual maintenance costs.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This stacked plate heat exchanger with a single-plate design, through the coordinated operation of a connecting frame, mounting plate, movable plate, bolts, stacked plates, inlet pipe, outlet pipe, roller, elastic telescopic plate, drum, long plate, hinge rod, positioning plate, and pressure cylinder, allows the equipment to be installed inside a factory or commercial facility for heat exchange. The mounting plate is installed at the front of the connecting frame, and the drum dampens the movable plate through the contraction end of the elastic telescopic plate. This allows the movable plate to more accurately position and press the stacked plates, preventing loosening during operation and ensuring accurate positioning of the plates in the vertical and horizontal directions, avoiding issues caused by rigid positioning holes. To prevent misalignment caused by insufficient sealing or human error, and to prevent sealing leaks caused by positioning deformation of the plates after disassembly or maintenance, the overall sealing reliability is improved and the heat exchange efficiency of the equipment is increased. When the stacked plates are shrunk and fixed, the moving plate moves and drives the positioning plate to squeeze the stacked plates, ensuring that the sealing gaskets between each plate are subjected to uniform force, thereby preventing local leakage or premature gasket failure. It can withstand the pressure difference between the media and maintain the stable position of the plates during operation, significantly reducing plate displacement or loosening caused by vibration. When disassembling, the plates can be quickly removed by simply loosening the clamping studs, shortening maintenance downtime and reducing maintenance costs.

[0009] 2. This stacked plate heat exchanger with a single-plate design, through the coordinated operation of the energy block, power line, L-shaped plate, and electric pole, addresses the corrosion phenomenon that may occur in the stacked plates during operation. To extend the equipment's service life, the movement of the movable plate drives the electric pole to output current for corrosion protection of the stacked plates. A weak current is applied to keep the plate potential below the corrosion potential, preventing corrosion reactions. By adjusting the current density, the protection intensity can be adjusted in real time according to the corrosiveness of the medium, temperature, flow rate, and other operating conditions, ensuring sufficient protection under different operating conditions, reducing safety risks such as leaks or explosions caused by corrosion, protecting personnel and equipment safety on the production site, and improving equipment efficiency.

[0010] 3. This stacked plate heat exchanger with a single plate design, through the coordinated operation of the wheel, guide groove, connecting rod, and anti-leakage plate, fixes the gas pipe to the inlet pipe during heat exchange. The anti-leakage plate will come closer to the connecting rod through the spring, thereby sealing the connection of the inlet pipe. It can generate a self-tightening effect under pressure, significantly increasing the contact pressure of the sealing surface, reducing the probability of leakage, maintaining the complete contact of the heat exchange surface, reducing thermal resistance, and improving the overall heat transfer coefficient.

[0011] 4. This stacked plate heat exchanger with a single plate design, through the cooperation of positioning blocks, buckles, and locking blocks, when sealing the leak-proof plate, the top leak-proof plate drives the buckles to cooperate with the locking blocks to fix it, preventing the seal from shifting or deforming during operation, thereby greatly reducing the risk of leakage. It also allows the seal to be quickly inserted or removed, significantly shortening the time for maintenance, cleaning, or replacement, and reducing downtime costs.

[0012] 5. This stacked plate heat exchanger with a single-plate design operates through the coordinated operation of piston plates, L-shaped rods, spiral rods, and circular plates. After heat exchange, the internal gas is discharged through the exhaust pipe. At this time, the internal gas pressure drives the piston plate to rotate, which in turn drives the circular plate to rotate and open the exhaust port, thereby achieving the effect of automatic exhaust. This maintains pressure balance, prevents equipment damage caused by pressure fluctuations, and realizes the self-regulation of system pressure. It not only ensures operational safety but also improves energy efficiency and equipment lifespan, while significantly reducing manual maintenance costs. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-8 One embodiment of the present invention is as follows: a stacked plate heat exchanger with a single plate design includes a connecting frame 1, a mounting plate 2 fixedly connected to the front side of the connecting frame 1, an air inlet pipe 8 fixedly connected to the front side of the mounting plate 2, an air outlet pipe 9 fixedly connected to the front side of the mounting plate 2, an air outlet mechanism 7 for indirect air outlet is provided on the inner wall of the air outlet pipe 9, a movable plate 3 is slidably connected to the inner wall of the connecting frame 1, a circular roller 10 is rotatably connected to the inner wall of the movable plate 3, stacked plate parts 5 are slidably connected to the inner wall of the connecting frame 1, bolts 4 are slidably connected to the inner wall of the movable plate 3, an anti-corrosion mechanism 6 for preventing equipment corrosion is provided on the front side of the movable plate 3, an elastic telescopic plate 11 is fixedly connected to the top of the connecting frame 1, a roller 12 is rotatably connected to the inner wall of the elastic telescopic plate 11, and the circumferential surface of the roller 12 contacts the circumferential surface of the roller 10. When heat exchange is performed in factories or commercial settings, the equipment can be installed inside. The mounting plate 2 is installed on the front of the connecting frame 1, and then the corresponding number of stacked plates 5 are installed inside the connecting frame 1. Simultaneously, the movable plate 3 is installed on the rear of the stacked plates 5. After installation, the bolt 4 slides into the interior of the movable plate 3. Turning the nut will retract the movable plate 3, thus fixing the stacked plates 5 in place. As the movable plate 3 slides, it will drive the circular roller 10 to move. The circular roller 10 will contact the circumferential surface of the roller 12, causing the roller 12 to drive the elastic telescopic plate 11 to retract. The roller 12 will dampen the movable plate 3 through the retracted end of the elastic telescopic plate 11, allowing the movable plate 3 to more accurately position and press the stacked plates 5, preventing loosening during operation and ensuring accurate positioning of the plates in the up, down, left, and right directions. This avoids misalignment caused by insufficient rigidity of the positioning holes or human error, prevents sealing leaks caused by positioning deformation after disassembly or maintenance, improves overall sealing reliability, and enhances the heat exchange efficiency of the equipment. The connecting frame 1 includes a bolt 4, and a long plate 13 is slidably connected to the circumferential surface of the bolt 4 via a spring. A hinge rod 14 is hinged to the inner wall of the long plate 13, and a positioning plate 15 is hinged to the inner wall of the hinge rod 14. A pressure cylinder 16 is rotatably connected to the inner wall of the positioning plate 15. The rear side of the mounting plate 2 contacts the circumferential surface of the pressure cylinder 16, the front side of the movable plate 3 contacts the circumferential surface of the pressure cylinder 16, the positioning plate 15 contacts both sides of the stacked plates 5, the front side of the movable plate 3 contacts the rear side of the stacked plates 5, and the rear side of the mounting plate 2 contacts the front side of the stacked plates 5. When the stacked plates 5 are retracted and fixed, the movable plate 3 will move and contact the rear side of the long plate 13. The movement of the long plate 13 will drive the hinge rod 14 to rotate through the hinge point. The rotation of the hinge rod 14 will move the positioning plate 15 to the position of the stacked plates 5 through the hinge point, thereby making the positioning plate 15 press against the stacked plates 5, ensuring that the sealing gaskets between each plate are subjected to uniform force, thus preventing local leakage or premature gasket failure. It can withstand the pressure difference between the media and maintain the stable position of the plates during operation, significantly reducing plate displacement or loosening caused by vibration. When disassembling, the plates can be quickly removed by simply loosening the clamping studs, shortening maintenance downtime and reducing maintenance costs.

[0017] Working principle: When heat exchange in factories or commercial settings, the equipment can be installed inside. At this time, the mounting plate 2 is installed on the front side of the connecting frame 1. The roller 12 will dampen the movable plate 3 through the contraction end of the elastic telescopic plate 11, so that the movable plate 3 can more accurately position and press the stacked plates 5, preventing the equipment from loosening during operation, ensuring accurate positioning of the plates in the up, down, left, and right directions, improving the overall sealing reliability, and increasing the heat exchange efficiency of the equipment. When the stacked plates 5 are contracted and fixed, the movable plate 3 moves to drive the positioning plate 15 to squeeze the stacked plates 5, ensuring that the sealing gaskets between each plate are subjected to uniform force, thereby preventing local leakage or premature gasket failure. When disassembling, simply loosen the clamping studs to quickly remove the plates, shortening maintenance downtime and reducing maintenance costs.

[0018] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the anti-corrosion mechanism 6 includes an energy block 61, the top of the connecting frame 1 is fixedly connected to the bottom of the energy block 61, the output end of the energy block 61 is fixedly connected to a power line 62, an L-shaped plate 63 is fixedly connected to the side of the power line 62 away from the energy block 61, an electric rod 64 is slidably connected to the inner wall of the L-shaped plate 63 by a spring, a wheel 65 is installed on the side of the L-shaped plate 63 near the connecting frame 1, and guide grooves 66 are opened on both sides of the connecting frame 1, with the inner wall of the guide groove 66 contacting the circumferential surface of the wheel 65; When the equipment is in operation, corrosion will occur on the stacked plates 5 inside the equipment. To improve the service life of the equipment, the movement of the movable plate 3 will drive the L-shaped plate 63 to move, which in turn drives the electric rod 64 to move. At the same time, the L-shaped plate 63 will drive the wheel 65 to move. The wheel 65 will contact the inner wall of the guide groove 66, thereby driving the L-shaped plate 63 to move downward. The L-shaped plate 63 will drive the electric rod 64 to move downward. The downward movement of the electric rod 64 will activate the energy block 61 to work. The energy block 61 will output current through the output terminal. The energy block 61 will output current to the electric rod 64 through the power line 62. The output of the electric rod 64 will provide current corrosion protection for the stacked plates 5. The weak current will keep the plate potential below the corrosion potential, preventing corrosion reaction. By adjusting the current density, the protection strength can be adjusted in real time according to the corrosiveness of the medium, temperature, flow rate and other working conditions to ensure that sufficient protection is provided under different operating conditions, reduce the safety risks of leakage or explosion caused by corrosion, ensure the safety of personnel and equipment on the production site, and improve the working efficiency of the equipment. The anti-corrosion mechanism 6 includes a connecting rod 67, which is fixedly connected to the circumferential surface of the air intake pipe 8. The connecting rod 67 is slidably connected to the anti-leakage plate 68 by a spring. The rear side of the L-shaped plate 63 is fixedly connected to the front side of the movable plate 3, and the inner wall of the anti-leakage plate 68 is in contact with the circumferential surface of the air intake pipe 8. During hot gas replacement, the gas pipe is fixedly connected to the inlet pipe 8. At this time, the connecting pipe is aligned with the inlet pipe. By manually moving the anti-leakage plate 68, and then releasing it, the anti-leakage plate 68 will be moved closer together by the spring between it and the connecting rod 67, thereby sealing the connection of the inlet pipe 8. It can generate a self-tightening effect under pressure, significantly increasing the contact pressure of the sealing surface, reducing the probability of leakage, maintaining the complete contact of the heat exchange surface, reducing thermal resistance, and improving the overall heat transfer coefficient.

[0019] Working principle: When the equipment is working, the stacked plates 5 inside the equipment will corrode. In order to improve the service life of the equipment, the movable plate 3 moves and drives the electric rod 64 to output current to prevent corrosion of the stacked plates 5. A weak current is passed in to make the plate potential lower than the corrosion potential, preventing corrosion reaction from occurring. By adjusting the current density, the safety risks such as leakage or explosion caused by corrosion are reduced, ensuring the safety of personnel and equipment on the production site and improving the working efficiency of the equipment. When performing hot gas replacement, the gas pipe is fixedly connected to the air inlet pipe 8. The anti-leakage plate 68 will come closer to each other with the spring between it and the connecting rod 67, thereby sealing the connection of the air inlet pipe 8. It can generate a self-tightening effect under pressure, significantly increasing the contact pressure of the sealing surface, reducing the probability of leakage, maintaining the complete contact of the heat exchange surface, reducing thermal resistance, and improving the overall heat transfer coefficient.

[0020] The air outlet mechanism 7 includes a positioning block 71, and the two sides of the anti-leakage plate 68 are fixedly connected to the positioning block 71. The inner wall of the positioning block 71 is rotatably connected to the buckle 72 by a torsion spring, and the two sides of the anti-leakage plate 68 are fixedly connected to the locking block 73. When sealing the leak-proof plate 68, the top leak-proof plate 68 drives the positioning block 71 to move, and the positioning block 71 drives the buckle 72 to move. The movement of the positioning block 71 will cause the inclined surface to contact the inclined surface of the buckle 73, thereby causing the buckle 72 to rotate. When the buckle 73 enters the interior of the buckle 72, the buckle 72 will be reset by the torsion spring on the inner wall of the positioning block 71, so that the buckle 72 cooperates with the buckle 73 to fix the leak-proof plate 68, preventing the seal from shifting or deforming during operation, thereby greatly reducing the risk of leakage, allowing the seal to be quickly snapped in or out, significantly shortening the time for maintenance, cleaning or replacement, and reducing downtime costs. The air outlet mechanism 7 includes a piston plate 74. The inner wall of the air outlet pipe 9 is rotatably connected to the piston plate 74 via a torsion spring. An L-shaped rod 75 is hinged to the inner wall of the piston plate 74 and is slidably connected to the inner wall of the air outlet pipe 9. A spiral rod 76 is fixedly connected to the inner wall of the L-shaped rod 75 and is slidably connected to the inner wall of the air outlet pipe 9. A circular plate 77 is rotatably connected to the inner wall of the air outlet pipe 9 and is in contact with the circumferential surface of the spiral rod 76. The inner wall of the buckle 72 is in contact with the buckle block 73 and the buckle 72 is in contact with both sides of the anti-leakage plate 68. A threaded groove is opened on the circumferential surface of the spiral rod 76. A movable block is fixedly connected to the inner wall of the circular plate 77 and is movably connected to the inner wall of the threaded groove. After heat exchange, the internal gas is discharged through the exhaust pipe 9. At this time, the internal gas pressure will drive the piston plate 74 to rotate. The rotation of the piston plate 74 will drive the L-shaped rod 75 to move through the hinge point. The L-shaped rod 75 will drive the spiral rod 76 to move. The spiral rod 76 will contact the movable block on the inner wall of the circular plate 77 through the spiral groove on the circumferential surface, thereby driving the circular plate 77 to rotate and opening the exhaust port. After the heat exchange is completed, the spiral rod 76 can be reset by the spring, and the circular plate 77 will close the exhaust port of the exhaust pipe 9, thereby achieving the effect of automatic exhaust, maintaining pressure balance, preventing equipment damage caused by pressure fluctuations, realizing the self-regulation of system pressure, ensuring operational safety, improving energy efficiency and equipment life, and significantly reducing manual maintenance costs.

[0021] Working principle: When sealing the anti-leakage plate 68, the top anti-leakage plate 68 drives the buckle 72 to cooperate with the locking block 73 for fixation, preventing the seal from shifting or deforming during operation, thereby greatly reducing the risk of leakage. This allows the seal to be quickly inserted or removed, significantly shortening the time for maintenance, cleaning, or replacement and reducing downtime costs. After heat replacement, the internal gas will be discharged through the vent pipe 9. At this time, the internal air pressure will push the piston plate 74 to rotate. The rotation of the piston plate 74 drives the circular plate 77 to rotate and open the vent hole, thereby achieving the effect of automatic venting, maintaining pressure balance, preventing equipment damage caused by pressure fluctuations, and realizing the self-regulation of system pressure. This not only ensures operational safety but also improves energy efficiency and equipment lifespan, while significantly reducing manual maintenance costs.
