Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a modular heat exchanger unit. Background Technology

[0002] A modular heat exchanger unit is a device that designs and assembles heat exchangers and related components in a modular fashion. It consists of multiple modules with the same or different functions, each module having a specific function.

[0003] Taking plate heat exchangers as an example, a plate heat exchanger unit is generally composed of a frame, plate modules, compression modules, and fluid inlet and outlet modules. Since the plate modules are attached to each other during operation, the internal space is difficult to expose, making it impossible to effectively remove dirt, impurities, and biofilms formed by microbial growth. During equipment maintenance, it is often necessary to manually and laboriously disassemble the plate modules one by one, which increases maintenance time and labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a modular heat exchanger unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A modular heat exchanger unit includes a frame, plate modules, a clamping module, and a medium inlet module. Plate modules are evenly arranged on one side of the frame. A clamping module is arranged on the side of the frame away from the plate modules. A lead screw is arranged in the frame on the side of the clamping module, and a driving block is sleeved on the lead screw. A pressure plate is arranged at the top of the driving block, and one side of the pressure plate is connected to the clamping module. A drive motor is arranged in the frame on the side of the lead screw, and the output end of the drive motor is connected to the lead screw. Medium inlet modules are respectively arranged at both ends of one side of the frame, and medium outlet modules are arranged on the frame on the side of the medium inlet modules. Grooves are respectively arranged at both ends of one side of the plate modules, and pop-out elements are evenly arranged inside the grooves through return springs.

[0006] Preferably, a limit rod is provided at the top of the machine frame, and a lower limit sleeve is fitted on the limit rod, with one end of the limit sleeve connected to the pressure plate.

[0007] Preferably, both the media inlet module and the media outlet module are provided with flanges at the ends away from the frame, and mounting holes are provided at the edges of the flanges.

[0008] Preferably, a filter screen is provided on one side of the inside of the medium inlet module, and a buckle is provided around the filter screen. The inner wall of the medium inlet module is uniformly provided with slots that match the buckles.

[0009] Preferably, each of the buckles has an embedded magnet inside, and each of the slots has a magnetic block inside.

[0010] Preferably, a limiting groove is provided on both sides of the groove, and a limiting block matching the limiting groove is provided on both sides of the pop-out part.

[0011] Preferably, each end of the plate module is provided with a sliding member, and each end of the frame is provided with a guide rod, and the sliding member is connected to the guide rod.

[0012] Preferably, corner holes are provided at all four corners of the plate module, and sealing gaskets are provided on the plate module outside the corner holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This modular heat exchanger unit is equipped with a frame, plate modules, a clamping module, a groove, a pop-out component, a return spring, and a limiting groove. The drive motor drives the lead screw to rotate, causing the drive block to move along the lead screw, thereby causing the clamping module to squeeze the plate module on one side, clamping it inside the frame and automatically completing the clamping process. This reduces the workload and labor intensity of manual operation and improves installation efficiency. The hot fluid and cold fluid enter through the medium inlet modules at the upper and lower ends, respectively, and enter their respective flow channels through the corner holes on the plate modules. The heat of the hot fluid is transferred to the cold fluid through the plate modules to achieve heat exchange. After the operation is completed, the drive motor drives the lead screw to rotate in the opposite direction, causing the drive block to separate the clamping module from the plate module. After the plate module loses pressure, the elastic component in the groove pops out under the action of the return spring, thereby helping the plate module to separate automatically, which facilitates subsequent maintenance, cleaning, and other operations, and reduces the workload and difficulty of manual disassembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-6 The present invention provides an embodiment of a modular heat exchanger unit, comprising a frame 1, plate modules 2, a pressing module 3 and a medium inlet module 4. Plate modules 2 are evenly arranged on one side inside the frame 1. Sliding parts 14 are provided at both ends of the plate modules 2. Guide rods 6 are provided at both ends inside the frame 1. The sliding parts 14 are connected to the guide rods 6.

[0024] Connect the sliding parts 14 at both ends of the plate module 2 to the guide rod 6 so that the plate module 2 can slide smoothly along the guide rod 6 and the plate module 2 can be evenly installed on one side inside the frame 1.

[0025] A clamping module 3 is provided inside the frame 1 on the side away from the plate module 2. A lead screw 7 is provided inside the frame 1 on the side of the clamping module 3, and a drive block 8 is sleeved on the lead screw 7. A pressure plate 12 is provided at the top of the drive block 8, and one side of the pressure plate 12 is connected to the clamping module 3.

[0026] A drive motor 9 is installed inside the frame 1 on one side of the lead screw 7, and the output end of the drive motor 9 is connected to the lead screw 7;

[0027] Start the drive motor 9, drive the lead screw 7 to rotate, drive the drive block 8 to move on the lead screw 7, and then drive the pressure plate 12 and the clamping module 3 to move towards the plate module 2, squeeze the plate module 2, and clamp it tightly inside the frame 1. The clamping process can be completed automatically, reducing the workload and labor intensity of manual operation and improving installation efficiency.

[0028] A limit rod 10 is provided at the top inside the frame 1, and a lower limit sleeve 11 is fitted on the limit rod 10. One end of the limit sleeve 11 is connected to the pressure plate 12 to guide and limit the pressure plate 12.

[0029] Medium inlet modules 4 are respectively installed at both ends of one side of the frame 1. Medium outlet modules 5 are installed on the frame 1 on the side of the medium inlet modules 4. Flanges 20 are installed at the ends of the medium inlet modules 4 and the medium outlet modules 5 away from the frame 1, and mounting holes are opened at the edges of the flanges 20 for connecting to pipelines.

[0030] Hot fluid and cold fluid enter from the media inlet modules 4 at both ends of one side of the frame 1, respectively. Each media inlet module 4 is equipped with a filter screen 19 on one side to filter impurities in the fluid entering the heat exchanger.

[0031] The filter screen 19 is provided with buckles 22 on all four sides, and the inner wall of the medium inlet module 4 is provided with slots 21 that match the buckles 22. The buckles 22 are provided with embedded magnets 23, and the slots 21 are provided with magnetic blocks 24.

[0032] Align the clips 22 around the filter screen 19 with the slots 21 on the inner wall of the media inlet module 4, and use the embedded magnets 23 and magnetic blocks 24 to attract each other to securely install the filter screen 19 in the media inlet module 4, which is convenient for installation and disassembly.

[0033] Corner holes 13 are provided at the four corners of the plate module 2, and sealing gaskets are provided on the plate module 2 outside the corner holes 13 to increase the sealing performance.

[0034] Hot fluid and cold fluid enter their respective flow channels through the corner holes 13 on the plate module 2. The two fluids flow in opposite directions or cross directions between adjacent plate modules 2 (one hot and one cold, alternating) without mixing. During the flow between the plate modules 2, the heat of the hot fluid is transferred to the cold fluid through the plate module 2 to achieve heat exchange (this is the prior art).

[0035] After heat exchange, the hot and cold fluids are discharged through the medium outlet module 5 and transported to subsequent processing or use stages through connected external pipelines.

[0036] The two ends of one side of the plate module 2 are respectively provided with grooves 15, and pop-out parts 16 are uniformly provided inside the grooves 15 through the reset springs 17;

[0037] When maintenance or cleaning of the heat exchanger is required, the drive motor 9 is started to rotate in reverse, which drives the lead screw 7 to rotate in reverse. The drive block 8 drives the clamping module 3 to separate from the plate module 2. After the plate module 2 loses the clamping force, the pop-out piece 16 in the groove 15 pops out under the action of the return spring 17, pushing the plate module 2 to separate automatically. This makes it easier for staff to perform maintenance operations such as inspection, cleaning or replacement of the plate module 2, reducing the workload and difficulty of manual disassembly.

[0038] Limiting grooves 18 are provided on both sides of the groove 15, and limiting blocks matching the limiting grooves 18 are provided on both sides of the pop-out piece 16. This ensures that the pop-out piece 16 can only move in a straight line along the direction of the limiting grooves 18, and prevents the pop-out piece 16 from shifting, shaking or rotating during pop-out or reset, thereby ensuring that it can pop out and reset accurately and realize the function of automatically separating the board module 2.

[0039] The specific model and specifications of the drive motor 9 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.

[0040] Working principle: In this embodiment, the sliding parts 14 at both ends of the plate module 2 are connected to the guide rod 6, allowing the plate module 2 to slide smoothly along the guide rod 6. The plate module 2 is evenly installed on one side inside the frame 1. The drive motor 9 is started, which drives the lead screw 7 to rotate. The drive block 8 moves on the lead screw 7, thereby driving the pressure plate 12 and the clamping module 3 to move towards the plate module 2, squeezing the plate module 2 and clamping it tightly inside the frame 1. At this time, the ejector 16 is pressed into the groove 15, ensuring a good seal between the plate modules 2. The clamping process is completed automatically, reducing the workload and labor intensity of manual operation and improving installation efficiency. The external pipeline system is connected to the medium inlet module 4 through the flange 20. Hot fluid and cold fluid enter from the medium inlet modules 4 at both ends of one side of the frame 1, respectively. A filter screen 19 is installed inside the medium inlet module 4. The buckles 22 around the filter screen 19 are aligned with the grooves 21 on the inner wall of the medium inlet module 4. The embedded magnet 23 attracts the magnetic block 24 in the slot 21, which securely installs the filter screen 19 in the medium inlet module 4 to filter impurities in the fluid entering the heat exchanger. The hot fluid and cold fluid enter their respective flow channels through the corner holes 13 on the plate module 2. During the flow between the plate modules 2, the heat of the hot fluid is transferred to the cold fluid through the plate module 2 to achieve heat exchange. After the heat exchange is completed, the hot fluid and cold fluid are discharged through the medium outlet module 5 and transported to the subsequent processing or use stage through the connected external pipeline. When the heat exchanger needs to be maintained or cleaned, the drive motor 9 is started to rotate in reverse, which drives the lead screw 7 to rotate in reverse. The drive block 8 drives the clamping module 3 to separate from the plate module 2. After the plate module 2 loses the clamping force, the pop-out piece 16 in the groove 15 pops out under the action of the return spring 17, pushing the plate module 2 to separate automatically. This makes it easier for the staff to inspect, clean or replace the plate module 2 and perform other maintenance operations, reducing the workload and difficulty of manual disassembly.
