Description

Technical Field

[0001] This application relates to the field of plate heat exchanger technology, and in particular to a high-efficiency and energy-saving plate heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers heat between two or more fluids through a solid wall or direct contact. Plate heat exchangers are a type of high-efficiency and compact heat exchange device, which is made of multiple sets of stamped corrugated metal plates stacked together. The plates are separated by sealing gaskets to form alternating cold and hot fluid channels. Its core function is to significantly improve heat transfer efficiency by increasing the heat transfer area and inducing turbulence. It is currently widely used in industries, energy and other fields.

[0003] In the prior art, plate heat exchangers generally include a frame, a fastening plate, fastening screws, and heat exchange plates. The upper end of the frame is provided with an installation rail, the fastening plate is slidably mounted on the installation rail, the heat exchange plates are disposed between the frame and the fastening plate, and one end is slidably mounted on the installation rail. The fastening screws are used to fasten the frame, heat exchange plates, and fastening plate. When it is necessary to clean the heat exchange plates, the fastening screws must first be removed. After removal, the fastening plate is moved to the side away from the heat exchange plates via the installation rail. Then, the heat exchange plates are disassembled one by one and cleaned, thereby achieving the cleaning of the heat exchange plates.

[0004] Regarding the aforementioned technologies, the cleaning process for heat exchange plates requires first removing the fastening bolts, then moving the fastening plate, and finally disassembling the heat exchange plates one by one before cleaning can be carried out. This process can be quite cumbersome, leading to reduced cleaning efficiency and increased labor costs. Therefore, improvements are proposed. Utility Model Content

[0005] In order to reduce labor costs and improve the cleaning efficiency of heat exchange plates, this application provides a high-efficiency and energy-saving plate heat exchanger.

[0006] The high-efficiency and energy-saving plate heat exchanger provided in this application adopts the following technical solution:

[0007] A high-efficiency and energy-saving plate heat exchanger includes a mounting frame with a horizontal rail at its upper end. A first clamping plate and a second clamping plate are provided at both ends of the mounting frame, with the upper end of the second clamping plate slidably mounted on the horizontal rail. Multiple sets of first and second plates are slidably mounted on the horizontal rail, with the first and second plates arranged alternately and located between the first and second clamping plates. The mounting frame is equipped with a moving component for equidistantly moving the first and second plates via the second clamping plates. The mounting frame also includes a washing and drying mechanism for cleaning and drying the first and second plates.

[0008] By adopting the above technical solution, when the first and second plates in the plate heat exchanger need to be cleaned, the moving component in this application can move the second clamping plate, the first plate, and the second plate along the horizontal rail on the mounting frame, so that the gap required for cleaning is created between the first and second plates. Then, the washing and drying mechanism in this application is used for cleaning and drying, thereby realizing rapid cleaning of the first and second plates, improving cleaning efficiency, and reducing the impact of plate heat exchanger shutdown on production.

[0009] Optionally, the movable component includes a first electric telescopic rod, a second electric telescopic rod, a first mounting block, a second mounting block, an elastic telescopic rod, a first connecting rod group, and a second connecting rod group. The fixed ends of the first electric telescopic rod and the second electric telescopic rod are both disposed on the mounting frame. The telescopic end of the first electric telescopic rod passes through the mounting frame and connects to the second clamping plate. Multiple sets of the first and second mounting blocks are provided. Multiple sets of the first mounting blocks are respectively disposed on the first plate, and multiple sets of the second mounting blocks are respectively disposed on the second plate. The first and second mounting blocks are respectively located on both sides of the cross rail. The telescopic end of the second electric telescopic rod passes through the first mounting frame and the second connecting rod group. The second clamping plate and the mounting bracket are connected to the second mounting block on the second plate adjacent to the second clamping plate. The elastic telescopic rod is disposed on the first clamping plate, and its telescopic end is connected to the first mounting block on the first plate near the first clamping plate. The first connecting rod group includes multiple sets of first connecting rods and multiple sets of second connecting rods. The multiple sets of first connecting rods and multiple sets of second connecting rods are respectively staggered and rotatably disposed on multiple sets of first mounting blocks, and the first connecting rods and second connecting rods on adjacent first mounting blocks are rotatably connected. The second connecting rod group is disposed with the first connecting rod group and is disposed on the second mounting block for moving the second plate.

[0010] By adopting the above technical solution, the first electric telescopic rod is first activated. The telescopic end of the first electric telescopic rod can drive the first mounting block and the second clamping plate to move away from the first clamping plate. While the first mounting block moves, it can drive the first connecting rod and the second connecting rod to move and rotate, eventually reaching a straight state. After reaching a straight state, the second connecting rod continues to move, which can drive the first mounting block and the first plate on the first plate to move. Since multiple sets of first plates are interconnected through multiple sets of first connecting rods and multiple sets of first mounting blocks, multiple sets of first plates can be moved. Before the first connecting rod and the second connecting rod are in a straight state, the second electric telescopic rod is activated. The telescopic end of the second electric telescopic rod can drive the second mounting block and the second plate to move. While the second mounting block on the second plate moves, it can drive the first connecting rod and the second connecting rod to move and rotate, eventually reaching a straight state.

[0011] After reaching a straight position, the second connecting rod continues to move, which can drive the second mounting block on the adjacent second plate and the adjacent second plate to move. Since multiple sets of second plates are connected to each other through multiple sets of second connecting rods and multiple sets of second mounting blocks, multiple sets of second plates can be moved. After the movement is completed, the first and second electric telescopic rods are closed, thereby separating the first and second plates from the first and second clamping plates, creating the necessary gap between the first and second plates for cleaning, so as to facilitate subsequent cleaning and drying. Compared with the prior art, which requires disassembling the plates before cleaning, this simplifies the workflow and improves work efficiency. The elastic telescopic rod can limit the movement of the first plate too far, while also allowing the first plate and the first clamping plate to fit tightly together when they are close to each other.

[0012] Optionally, the washing and drying mechanism includes a water tank, a water pump, a solenoid valve, a water outlet pipe, a spray pipe, and a drying assembly. The water tank is located on one side of the mounting frame, the water outlet pipe is located on the mounting frame, the water inlet of the water pump is connected to the water tank, and the water outlet is connected to the water outlet pipe. The end of the water outlet pipe away from the water pump is closed. The solenoid valve is located on the water outlet pipe. One end of the spray pipe is located on the water outlet pipe, and the other end is located above the first plate and the second plate. The drying assembly is located on the mounting frame and is used to dry the first plate and the second plate after washing.

[0013] By adopting the above technical solution, the water pump is started and the solenoid valve is opened, allowing water in the storage tank to enter the outlet pipe and spray pipe through the water pump. Finally, the water is sprayed out from the end of the spray pipe near the first and second plates, thereby achieving rapid cleaning of the first and second plates. This reduces the time spent on manual disassembly, cleaning, and reassembly, minimizes the impact of plate heat exchanger shutdown on production, and improves the production efficiency of the heat exchanger. In addition, the solenoid valve can regulate the water flow rate in the outlet pipe to ensure the cleaning effect on the first and second plates.

[0014] Optionally, the drying assembly includes a hot air dryer, a main air duct, and an air outlet duct. The hot air dryer is disposed on one side of the mounting frame. The main air duct is disposed on the mounting frame, with one end connected to the air outlet of the hot air dryer and the other end in a closed state. One end of the air outlet duct is disposed on the main air duct, and the other end is disposed above the first plate and the second plate.

[0015] By adopting the above technical solution, the hot air dryer is started, and hot air enters the main air duct and the air outlet duct. Finally, it is blown out from the end of the air outlet duct near the first and second plates, thereby achieving rapid evaporation of residual moisture on the first and second plates, shortening the drying time, and enabling the plate heat exchanger to be put into use more quickly, further improving the production efficiency of the heat exchanger.

[0016] Optionally, a metal flexible hose is installed at the end of the spray pipe away from the water outlet pipe and at the end of the air outlet pipe away from the main air pipe.

[0017] By adopting the above technical solution, the shape of the metal-shaped flexible tube can be changed, thereby allowing for adjustment of its position and angle according to requirements.

[0018] Optionally, the bottom of the mounting bracket is provided with an auxiliary rail to prevent the first plate and the second plate from tilting during movement.

[0019] By adopting the above technical solution, the auxiliary rail at the bottom of the mounting frame can prevent the first plate and the second plate from tilting during movement, thereby ensuring that the first plate and the second plate move stably along the horizontal rail and the auxiliary rail. In addition, the auxiliary rail can also ensure that the first plate and the second plate remain stable during the cleaning and drying process, thereby improving the cleaning and drying effect.

[0020] Optionally, a collection box for collecting sewage is provided below the auxiliary rail.

[0021] By adopting the above technical solution, the collection box installed below the auxiliary rail can collect the wastewater from cleaning the first and second plates, thereby reducing the amount of wastewater flowing to the outside and reducing the impact of wastewater on the outside.

[0022] Optionally, a control cabinet is provided on one side of the mounting frame for coordinating and centrally controlling the operation of the first electric telescopic rod, the second electric telescopic rod, the water pump, the solenoid valve, and the hot air dryer.

[0023] By adopting the above technical solution, the control cabinet can coordinate and centrally control the first electric telescopic rod, the second electric telescopic rod, the water pump, the solenoid valve, and the hot air dryer, thereby reducing labor costs and improving the operating efficiency of the device.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The washing and drying mechanism in this application can quickly clean the first and second plates. By starting the water pump and opening the solenoid valve, water in the water tank enters the outlet pipe and spray pipe through the water pump, and is finally sprayed out from the ends of the spray pipe near the first and second plates, thereby achieving rapid cleaning of the first and second plates, reducing the time spent on manual disassembly, cleaning and reassembly, reducing the impact of plate heat exchanger shutdown on production, and improving the production efficiency of the heat exchanger; in addition, the solenoid valve can regulate the water flow rate in the outlet pipe to ensure the cleaning effect on the first and second plates;

[0026] 2. The drying component in this application can quickly dry the first and second plates after cleaning.

[0033] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0034] This application discloses a high-efficiency and energy-saving plate heat exchanger, referring to... Figure 1 and Figure 2 The system includes a mounting frame 1, with a horizontal rail 11 fixedly mounted on the upper end of the mounting frame 1. A first clamping plate 12 and a second clamping plate 13 are mounted on both ends of the mounting frame 1, and the upper end of the second clamping plate 13 is slidably mounted on the horizontal rail 11. Multiple sets of first plates and second plates are slidably mounted on the horizontal rail 11. The first plates and second plates are staggered and are located between the first clamping plate 12 and the second clamping plate 13. A moving component 2 and a washing and drying mechanism 3 are mounted on the mounting frame 1.

[0035] When the first and second plates in the plate heat exchanger need to be cleaned, the moving component 2 in this embodiment can move the second clamping plate 13, the first plate, and the second plate along the horizontal rail 11 on the mounting frame 1, so that the first plate and the second plate have the spacing required for cleaning. Then, the washing and drying mechanism 3 in this embodiment is used for cleaning and drying, thereby realizing rapid cleaning of the first and second plates, improving cleaning efficiency, and reducing the impact of plate heat exchanger shutdown on production.

[0036] Reference Figure 1 , Figure 2 and Figure 3Compared to existing technologies that require disassembling and cleaning the plates, the movable component 2 in this embodiment includes a first electric telescopic rod 21, a second electric telescopic rod 27, a first mounting block 22, a second mounting block 25, an elastic telescopic rod 26, a first connecting rod group, and a second connecting rod group. The fixed ends of the first electric telescopic rod 21 and the second electric telescopic rod 27 are both fixedly mounted on the mounting frame 1. The telescopic end of the first electric telescopic rod 21 passes through the mounting frame 1 and connects to the second clamping plate 13. Multiple sets of the first mounting block 22 and the second mounting block 25 are provided. Multiple sets of the first mounting block 22 are respectively fixedly mounted on the first plate, and multiple sets of the second mounting block 25 are respectively fixedly mounted on the second plate. Located on both sides of the horizontal rail 11, the telescopic end of the second electric telescopic rod 27 passes through the second clamping plate 13 and the mounting bracket 1, and is connected to the second mounting block 25 on the second plate adjacent to the second clamping plate 13. The elastic telescopic rod 26 is fixedly installed on the first clamping plate 12, and its telescopic end is connected to the first mounting block 22 on the first plate near the first clamping plate 12. The first connecting rod group includes multiple sets of first connecting rods 23 and multiple sets of second connecting rods 24. The multiple sets of first connecting rods 23 and multiple sets of second connecting rods 24 are respectively staggered and rotatably installed on multiple sets of first mounting blocks 22, and the first connecting rods 23 and second connecting rods 24 on adjacent first mounting blocks 22 are rotatably connected. The second connecting rod group is set with the first connecting rod group and is installed on the second mounting block 25.

[0037] First, the first electric telescopic rod 21 is activated. The telescopic end of the first electric telescopic rod 21 can drive the first mounting block 22 and the second clamping plate 13 to move away from the first clamping plate 12. While the first mounting block 22 moves, it can drive the first connecting rod 23 and the second connecting rod 24 to move and rotate, eventually reaching a straight state. After reaching a straight state, the second connecting rod 24 continues to move, which can drive the first mounting block 22 and the first plate on the first plate to move. Since multiple sets of first plates are interconnected through multiple sets of first connecting rods and multiple sets of first mounting blocks 22, multiple sets of first plates can be moved. Before the first connecting rod 23 and the second connecting rod 24 reach a straight state, the second electric telescopic rod 27 is activated. The telescopic end of the second electric telescopic rod 27 can drive the second mounting block 25 and the second plate to move. While the second mounting block 25 on the second plate moves, it can drive the first connecting rod 23 and the second connecting rod 24 to move and rotate, eventually reaching a straight state.

[0038] After reaching a straight position, the second connecting rod 24 continues to move, which can drive the second mounting block 25 on the adjacent second plate and the adjacent second plate to move. Since multiple sets of second plates are interconnected through multiple sets of second connecting rods and multiple sets of second mounting blocks 25, multiple sets of second plates can be moved. After the movement is completed, the first electric telescopic rod 21 and the second electric telescopic rod 27 are closed, thereby separating the first and second plates from the first clamping plate 12 and the second clamping plate 13, creating the necessary spacing between the first and second plates for cleaning, so as to facilitate subsequent cleaning. Compared to the prior art which requires disassembling the plates before cleaning, the cleaning and drying process simplifies the workflow and improves work efficiency. The elastic telescopic rod 26 can limit the movement of the first plate too far, and can also make the first plate and the first clamping plate 12 fit tightly when they are close to each other. In this embodiment, three sets of first electric telescopic rods 21 are provided, of which the other two sets of first electric telescopic rods 21 are fixedly installed on the mounting frame 1, and the telescopic end is fixedly installed on the second clamping plate. The other two sets of first electric telescopic rods 21 can keep the second clamping plate 13 stable during the movement.

[0039] Reference Figure 1 and Figure 2 To achieve rapid cleaning of the first and second plates, the washing and drying mechanism 3 in this embodiment includes a water tank 31, a water pump 32, a solenoid valve 33, a water outlet pipe 34, a spray pipe 35, and a drying assembly 4. The water tank 31 is fixedly installed on one side of the mounting frame 1, and the water outlet pipe 34 is fixedly installed on the mounting frame 1. The water inlet end of the water pump 32 is connected to the water tank 31, and the water outlet end is connected to the water outlet pipe 34. The end of the water outlet pipe 34 away from the water pump 32 is closed. The solenoid valve 33 is fixedly installed on the water outlet pipe 34. One end of the spray pipe 35 is welded to the water outlet pipe 34, and the other end is fixedly installed above the first and second plates. The drying assembly 4 is installed on the mounting frame 1.

[0040] The water pump 32 is started and the solenoid valve 33 is opened, allowing water in the water storage tank 31 to enter the outlet pipe 34 and spray pipe 35 through the water pump 32. Finally, the water is sprayed out from the end of the spray pipe 35 near the first and second plates, thereby achieving rapid cleaning of the first and second plates. This reduces the time spent on manual disassembly, cleaning, and reassembly, minimizes the impact of plate heat exchanger shutdown on production, and improves the production efficiency of the heat exchanger. In addition, the solenoid valve 33 can regulate the water flow rate in the outlet pipe 34 to ensure the cleaning effect on the first and second plates. In this embodiment, the water pump 32 is a water-air dual-purpose pump, which can first clean the first and second plates, and then continue to dry the first and second plates after cleaning.

[0041] Reference Figure 2 and Figure 3After cleaning, the first and second plates may still have residual moisture. In order to put the plate heat exchanger into use more quickly, the drying component 4 in this embodiment includes a hot air dryer 41, a main air duct 42 and an air outlet duct 43. The hot air dryer 41 is fixedly installed on one side of the mounting frame 1. The main air duct 42 is fixedly installed on the mounting frame 1, with one end connected to the air outlet of the hot air dryer 41 and the other end in a closed state. One end of the air outlet duct 43 is welded to the main air duct 42, and the other end is fixedly installed above the first and second plates.

[0042] The hot air dryer 41 is started, and hot air enters the main air duct 42 and the air outlet duct 43. Finally, the air is blown out from the end of the air outlet duct 43 near the first and second plates, thereby achieving rapid evaporation of residual moisture on the first and second plates, shortening the drying time, and enabling the plate heat exchanger to be put into use more quickly, further improving the production efficiency of the heat exchanger. In this embodiment, the main air duct 42 is also equipped with a water-air dual-purpose pump. The water inlet of the water-air dual-purpose pump is connected to a water storage tank 31. A valve is installed at the end of the main air duct 42 near the hot air dryer 41 to prevent water backflow in the main air duct 42. Since the air outlet duct 43 and the spray pipe 35 are installed in different positions, there may be areas that cannot be covered, resulting in poor cleaning and drying effects on the first and second plates. The water-air dual-purpose pump allows the air outlet duct 43 and the spray pipe 35 to clean the first and second plates before drying, which can reduce the areas that cannot be covered, thereby improving the cleaning and drying effects on the first and second plates.

[0043] Reference Figure 1 and Figure 3 During the cleaning and drying of the first and second plates, the position and angle of the cleaning and drying may need to be adjusted according to actual work requirements. Therefore, in this embodiment, a metal-shaped flexible hose 36 is fixedly installed at the end of the spray pipe 35 away from the water outlet pipe 34 and the end of the air outlet pipe 43 away from the main air pipe 42. The metal-shaped flexible hose 36 can change shape, thereby allowing for adjustment of position and angle as needed to ensure the cleaning and drying effect on the first and second plates. In this embodiment, the metal-shaped flexible hose 36 also... It can be a universal joint tube or a spherical guide tube. The universal joint tube can also be adjusted in position and angle according to the requirements. Specifically, the spherical guide tube is a spherical body that is rotatably installed on the inner peripheral wall of the air outlet pipe 43 and the spray pipe 35 near the ends of the first plate and the second plate. The spherical body has a cylindrical groove for water and hot air to pass through. A ball sleeve is installed between the spherical body and the inner peripheral wall of the air outlet pipe 43 and the spray pipe 35. The angle of water and hot air can be adjusted by rotating the spherical body. The ball sleeve can reduce the passage of water and hot air between the spherical body and the inner peripheral wall of the air outlet pipe 43 and the spray pipe 35.

[0044] Reference Figure 1During the movement of the first and second plates, the first and second plates may tilt. Therefore, in this embodiment, the mounting bracket 1 is fixedly installed with an auxiliary rail 15 at the bottom. The auxiliary rail 15 can prevent the first and second plates from tilting during the movement, thereby ensuring that the first and second plates move stably along the horizontal rail 11 and the auxiliary rail 15. In addition, the auxiliary rail 15 can also ensure that the first and second plates remain stable during the cleaning and drying process, thereby improving the cleaning and drying effect.

[0045] Reference Figure 1 Wastewater will flow out during the cleaning of the first and second plates. To collect the wastewater, a collection box 16 is fixedly installed below the auxiliary rail 15 in this embodiment. The bottom of the collection box 16 has a drain outlet, and a drain pipe is fixedly installed at the drain outlet. The collection box 16 can collect the wastewater from cleaning the first and second plates, thereby reducing the amount of wastewater flowing to the outside and reducing the impact of wastewater on the outside. When the wastewater in the collection box 16 needs to be discharged, the drain pipe is opened, and the wastewater can flow out from the drain outlet and the drain pipe, thereby achieving rapid wastewater treatment and facilitating operation by staff.

[0046] Reference Figure 2 In order to reduce labor costs and improve the operating efficiency of the device, a control cabinet 14 is fixedly installed on one side of the mounting frame 1 in this embodiment, which can coordinate and centrally control the operation of the first electric telescopic rod 21, the second electric telescopic rod 27, the water pump 32, the solenoid valve 33 and the hot air dryer 41.

[0047] The implementation principle of a high-efficiency energy-saving plate heat exchanger according to an embodiment of this application is as follows:

[0048] The water pump 32 is started and the solenoid valve 33 is opened, allowing water in the water storage tank 31 to enter the outlet pipe 34 and spray pipe 35 through the water pump 32. Finally, the water is sprayed out from the end of the spray pipe 35 near the first and second plates, thereby achieving rapid cleaning of the first and second plates. This reduces the time spent on manual disassembly, cleaning, and reassembly, minimizes the impact of plate heat exchanger shutdown on production, and improves the production efficiency of the heat exchanger. In addition, the solenoid valve 33 can regulate the water flow rate in the outlet pipe 34 to ensure the cleaning effect on the first and second plates.

[0049] Start the hot air dryer 41, and hot air enters the main air pipe 42 and the air outlet pipe 43. Finally, it is blown out from the end of the air outlet pipe 43 near the first plate and the second plate, thereby achieving rapid evaporation of residual moisture on the first plate and the second plate, shortening the drying time, so that the plate heat exchanger can be put back into use more quickly, and further improving the production efficiency of the heat exchanger.

[0050] In this embodiment, the control cabinet 14 can coordinate and centrally control the first electric telescopic rod 21, the second electric telescopic rod 27, the water pump 32, the solenoid valve 33, and the hot air dryer 41, thereby reducing labor costs and improving the operating efficiency of the device.
