Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a plate heat exchanger suitable for multiple operating conditions. Background Technology

[0002] The detachable plate heat exchanger is made of many stamped corrugated thin plates spaced at certain intervals, sealed around the perimeter by gaskets, and overlapped and pressed together by a frame and a clamping screw. The four corner holes of the plates and gaskets form the distribution pipes and collection pipes of the fluid, while also reasonably separating the hot and cold fluids so that they flow in the flow channels on both sides of each plate and exchange heat through the plates.

[0003] Because existing plate heat exchangers require users to shut them down before cleaning or replacing the plates when leaks occur, the operation is cumbersome and inconvenient. Furthermore, existing plate heat exchangers operate in diverse environments and often experience slight vibrations during operation, which can affect the flow of the medium inside the heat exchanger and thus its efficiency. In addition, there are various types of existing plate heat exchangers, each suitable for different operating conditions. Utility Model Content

[0004] The purpose of this invention is to provide a plate heat exchanger suitable for multiple operating conditions, 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: A plate heat exchanger suitable for multiple operating conditions, comprising a front-end plate: a plate assembly is provided on one side of the front-end plate, a rear-end plate is installed on one side of the plate assembly, fasteners are provided on the top, bottom, and sides of the front-end plate and the rear-end plate, a first limiting member and a second limiting member are respectively provided on the top and bottom of one side of the front-end plate, a connecting plate is provided on one side of the first limiting member, support plates are provided at both ends of the bottom of the front-end plate and the connecting plate, a limiting rod is slidably provided on the front-end plate and the connecting plate through the support plate, a spring is provided at the bottom of the support plate, an mounting plate is provided at the bottom of the limiting rod and the spring, a push plate is provided on one side of the outer surface of the first limiting member, a blocking member is provided at each of the four corners of the other side of the push plate, a lead screw is provided at the middle position of one side of the connecting plate, and a flow direction adjustment structure is provided at each of the four corners of the other side of the front-end plate.

[0006] By adopting the above technical solution, users can clamp and fix the front plate, plate assembly, and rear plate with fasteners. The first and second limiting components can assist in the installation of the plate assembly, facilitating the installation or cleaning of the plates. If a leak occurs on the plate assembly, the user can rotate the screw to move the push plate along the screw, thereby pushing the plugging component to move inside the inner tube and sealing the plate corresponding to the leak location on the plate assembly. This solves the problem of heat exchanger leakage during use, allowing users to replace the heat exchanger after it stops working, avoiding any impact on work efficiency. At the same time, the support plate, limiting rod, spring, and mounting plate work together to provide a buffer in swaying environments, preventing the flow of the medium inside the heat exchanger from being affected by violent shaking.

[0007] Preferably, the flow direction adjustment structure includes an outer tube, an inner tube rotatably disposed on the inner surface of the outer tube, a plurality of first openings are equidistantly arranged on the outer surface of the outer tube, and a plurality of second openings are equidistantly arranged on the outer surface of the inner tube.

[0008] By adopting the above technical solution, since four flow direction adjustment structures are set on the front end plate, and since the other side of the inner tube is provided with a rim, and the other side of the outer tube can be rotatably connected to the inner tube through the rim, and the outer tube can be connected to the plate assembly, the user can adjust the position of the second opening by rotating the inner tube, so that the second opening at different positions is connected to the first opening on the outer tube, so that the flow mode of the medium in the heat exchanger can be changed accordingly, and the heat exchanger can be adapted to different equipment, thereby adapting to different working conditions.

[0009] Preferably, rollers are provided at the middle position of the top of the rear end plate and the push plate, the first limiting member is slidably connected to the rear end plate and the push plate through the rollers, and the bottom of the rear end plate is slidably connected to the second limiting member.

[0010] By adopting the above technical solution, when the user needs to clean or replace the plates on the plate assembly, the rear plate can move smoothly on the first and second limiting parts, which can prevent the rear plate and plate assembly from shifting during assembly.

[0011] Preferably, the support plate has round holes at both ends of its top, and the support plate is slidably connected to the limiting rod through the round holes. The mounting plate has mounting holes at its bottom.

[0012] By adopting the above technical solution, the limiting rod can slide smoothly on the support plate through the round hole, and the limiting rod is provided with a square block to prevent the limiting rod from detaching from the support plate.

[0013] Preferably, the front end plate and the rear end plate are provided with connecting grooves at the top, bottom and sides, and the front end plate and the rear end plate are connected to fasteners through the connecting grooves. The plate group is provided with a groove at the middle position of the top and bottom, and the size of the groove on the plate group is slightly larger than the size of the first limiting member and the second limiting member.

[0014] By adopting the above technical solution, the fasteners can be stably and securely installed on the front and rear plates through the connecting grooves, which can prevent the fasteners from falling off the front and rear plates.

[0015] Preferably, a connection port is provided at the middle position on one side of the connecting plate, and the connecting plate is rotatably connected to the lead screw through the connection port. A threaded hole is provided at the middle position on one side of the push plate, and the lead screw is threadedly connected to the push plate through the threaded hole.

[0016] By adopting the above technical solution, the lead screw can rotate on the connecting plate through the connection port. When the lead screw rotates, the push plate can move along the lead screw through the threaded hole, thereby driving the blocking component to move in the rear end plate and the inner tube.

[0017] Preferably, a sealing port is provided at each of the four top corners on one side of the rear end plate, the plugging component is slidably connected to the rear end plate through the sealing port, and the inner tube is slidably connected to the plugging component.

[0018] By adopting the above technical solution, a sealing ring is provided on the other side of the outer surface of the plugging component. The sealing ring and the sealing port cooperate to prevent the medium from leaking from the sealing port.

[0019] Preferably, there are multiple second openings, and the multiple second openings are staggered on the bottom and one side of the outer surface of the inner tube, and the opening position of the first opening corresponds to the opening position of the second opening.

[0020] By adopting the above technical solution, the plate group is composed of multiple plates stacked together, and a flow groove is provided on one side of the plate. Multiple first openings on the outer tube correspond to the flow grooves on each plate. When the user rotates the outer tube, the second openings at different positions on the outer tube can be connected with the first openings, thereby controlling the flow of the medium in the flow direction adjustment structure within the flow grooves on different plates, thereby changing the medium flow mode.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This is applicable to multi-condition plate heat exchangers. Through the cooperation between the push plate, the plugging component, and the screw, when a leak occurs in the plate assembly, the user can drive the push plate to move on the screw by rotating the screw, so that the plugging component can slide inside the inner tube, thereby sealing the second opening on the inner tube, preventing the medium from flowing to the leak in the plate assembly, and allowing the heat exchanger to work normally without the user having to shut down the heat exchanger.

[0023] 2. This is applicable to multi-condition plate heat exchangers. It is equipped with a support plate, a limiting rod, a spring, and a mounting plate. When the plate heat exchanger is working, the support plate, the limiting rod, and the spring work together to reduce the vibration amplitude of the plate heat exchanger, so as to avoid affecting the flow of the medium inside the heat exchanger and thus prevent the working efficiency of the plate heat exchanger from being affected.

[0024] 3. This plate heat exchanger is suitable for multiple operating conditions and is equipped with a flow direction adjustment structure. By rotating the inner tube, the user can connect the second opening at different positions on the inner tube with the first opening, thereby adjusting the flow of the medium in the flow grooves of different plates, thus changing the flow mode of the medium in the heat exchanger and enabling the heat exchanger to be used in different scenarios.

If a leak occurs on plate group 2, the user can rotate the screw 14 to move the push plate 12 along the screw 14, thereby pushing the blocking member 13 to move in the inner tube 151 to seal the plate corresponding to the leak position on plate group 2. This can solve the problem of heat exchanger leakage during the use of the heat exchanger, allowing the user to replace the heat exchanger after it stops working, avoiding the impact on working efficiency. At the same time, the support plate 8, limiting rod 9, spring 10, and mounting plate 11 work together to provide a buffer in a shaking environment, preventing the flow of the medium inside the heat exchanger from being affected by violent shaking. Furthermore, the flow direction adjustment structure 15 can adjust the flow mode of the medium in the heat exchanger. With the structure described above, the heat exchanger can be used in various working conditions.

Since four flow direction adjustment structures 15 are disposed on the front end plate 1, and since the other side of the inner tube 151 is provided with a rim, and the other side of the outer tube 150 can be rotatably connected to the inner tube 151 through the rim, and the outer tube 150 can be connected to the plate group 2, the user can adjust the position of the second openings 153 by rotating the inner tube 151, so that the second openings 153 at different positions are connected to the first openings 152 on the outer tube 150, so that the flow mode of the medium in the heat exchanger can be changed accordingly, so that the heat exchanger can be adapted to different equipment, and thus adapt to different working conditions.

[0033] In this embodiment, rollers are provided at the middle position of the top of the rear end plate 3 and the push plate 12. The first limiting member 5 is slidably connected to the rear end plate 3 and the push plate 12 through the rollers. The bottom of the rear end plate 3 is slidably connected to the second limiting member 6. When the user needs to clean or replace the plates on the plate group 2, the rear end plate 3 can move smoothly on the first limiting member 5 and the second limiting member 6, which can prevent the rear end plate 3 and the plate group 2 from shifting during assembly.

[0034] In this embodiment, round holes are provided at both ends of the top of the support plate 8. The support plate 8 is slidably connected to the limiting rod 9 through the round holes. The bottom of the mounting plate 11 is provided with mounting holes. The limiting rod 9 can slide smoothly on the support plate 8 through the round holes. Moreover, a square block is provided on the limiting rod 9 to prevent the limiting rod 9 from detaching from the support plate 8.

[0035] In this embodiment, the front plate 1 and the rear plate 3 are provided with connecting grooves on the top, bottom and sides. The front plate 1 and the rear plate 3 are connected to the fastener 4 through the connecting grooves. The plate group 2 is provided with grooves in the middle of the top and bottom. The size of the grooves on the plate group 2 is slightly larger than the size of the first limiting member 5 and the second limiting member 6. The fastener 4 can be stably and firmly installed on the front plate 1 and the rear plate 3 through the connecting grooves, which can prevent the fastener 4 from falling off the front plate 1 and the rear plate 3.

[0036] In this embodiment, a connection port is provided at the middle position on one side of the connecting plate 7. The connecting plate 7 is rotatably connected to the lead screw 14 through the connection port. A threaded hole is provided at the middle position on one side of the push plate 12. The lead screw 14 is threadedly connected to the push plate 12 through the threaded hole. The lead screw 14 can rotate on the connecting plate 7 through the connection port. When the lead screw 14 rotates, the push plate 12 can move along the lead screw 14 through the threaded hole, thereby driving the blocking component 13 to move in the rear end plate 3 and the inner tube 151.

[0037] In this embodiment, sealing ports are provided at the four top corners on one side of the rear end plate 3. The plug 13 is slidably connected to the rear end plate 3 through the sealing ports. The inner tube 151 is slidably connected to the plug 13. A sealing ring is provided on the other side of the outer surface of the plug 13. The sealing ring and the sealing port cooperate to prevent the medium from leaking from the sealing port.

[0038] In this embodiment, there are multiple second openings 153, which are staggered on the bottom and one side of the outer surface of the inner tube 151.

The plate group 2 is composed of multiple plates stacked together, and a flow groove is provided on one side of the plate. The multiple first openings 152 on the outer tube 150 correspond to the flow groove on each plate. When the user rotates the outer tube 150, the second openings 153 at different positions on the outer tube 150 can be connected with the first openings 152, thereby controlling the flow of the medium in the flow direction adjustment structure 15 in the flow grooves on different plates, thereby changing the medium flow mode.

[0039] Working principle: The user can clamp and fix the front plate 1, plate group 2, and rear plate 3 using fastener 4. The first limiting member 5 and the second limiting member 6 assist in the installation of plate group 2, facilitating plate installation or cleaning. If leakage occurs on plate group 2, the user can rotate the screw 14 to move the push plate 12 along the screw 14, thereby pushing the blocking member 13 to move within the inner tube 151, sealing the plate corresponding to the leakage location on plate group 2. This solves the problem of heat exchanger leakage during use, allowing the user to replace the heat exchanger after it stops working, avoiding impact on working efficiency. At the same time, the support plate 8, limiting rod 9, spring 10, and mounting plate 11 work together to provide a buffer in swaying environments, preventing... The flow of the medium inside the heat exchanger is affected by violent shaking. Because four flow direction adjustment structures 15 are provided on the front plate 1, and the other side of the inner tube 151 is provided with a rim, the other side of the outer tube 150 can be rotatably connected to the inner tube 151 through the rim. The outer tube 150 can be connected to the plate group 2. Since the plate group 2 is composed of multiple stacked plates, and one side of the plate is provided with a flow groove, the multiple first openings 152 on the outer tube 150 correspond to the flow grooves on each plate. When the user rotates the outer tube 150, the second openings 153 at different positions on the outer tube 150 can be connected to the first openings 152, thereby controlling the flow of the medium in the flow direction adjustment structure 15 in the flow grooves on different plates, thereby changing the medium flow mode.
