Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchangers, and more particularly to plate heat exchangers based on quick assembly and disassembly. Background Technology
[0002] Plate heat exchangers are highly efficient heat exchange devices widely used in various industrial fields, including chemical, pharmaceutical, food processing, HVAC, and energy. They consist of multiple parallel metal plates connected together by sealing gaskets to form a series of flow channels through which hot and cold fluids flow separately, completing the heat exchange.
[0003] However, in the use of existing plate heat exchangers, bolts are usually used for fixing. If maintenance or cleaning of the equipment is required, the disassembly and assembly process is complicated and time-consuming, which will lead to prolonged equipment downtime and thus affect production efficiency. In other words, it is difficult to achieve rapid installation and removal of heat exchange plates.
[0004] Furthermore, due to the lack of a stable structure, the pipeline will vibrate during fluid flow. With prolonged use, this may lead to leakage at the pipeline joints, resulting in the loss of hot or cold fluid, affecting heat exchange efficiency, and potentially causing more serious safety issues, namely, difficulty in ensuring the stability of the pipeline during operation.
[0005] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a plate heat exchanger based on quick assembly and disassembly, so as to solve the technical defects mentioned in the background art.
[0007] The purpose of this utility model can be achieved through the following technical solution: a plate heat exchanger based on quick assembly and disassembly, including a first fixed plate and a second fixed plate, with multiple heat exchange plates fixedly installed between the first fixed plate and the second fixed plate, and connecting pipes fixedly installed on both the first fixed plate and the second fixed plate.
[0008] A disassembly assembly is fixedly installed on the second fixed plate. The disassembly assembly includes a connecting rod, a plug rod, and a rotating plate. One end of the connecting rod is fixedly connected to the first fixed plate. The plug rod is movably installed on the second fixed plate. A plug hole is opened on the connecting rod, and one end of the plug rod is located in the plug hole.
[0009] The rotating plate is movably mounted on the fixed plate 2. The rotating plate is located on one side of the insertion rod, and a locking block is fixedly installed on the rotating plate.
[0010] Preferably, a fixing tube is fixedly installed on the fixing plate 2, the insertion rod is movably installed in the fixing tube, and a reset plate is movably installed in the fixing tube, with the reset plate fixedly connected to the insertion rod.
[0011] Preferably, a spring is fixedly installed on one side of the reset plate, and the end of the spring away from the reset plate is fixedly connected to the fixing tube.
[0012] Preferably, the fixed plate 2 has a groove, and the rotating plate is engaged and installed in the groove.
[0013] Preferably, multiple connecting pipes are provided, as are multiple fixed pipes and rotating plates, with the rotating plate located above the connecting pipes.
[0014] Preferably, a support block is fixedly installed on the side of both the fixing plate 1 and the fixing plate 2 away from the heat exchange fins, and the support block is located at the bottom of the fixing block 1 and the fixing block 2.
[0015] The beneficial effects of this utility model are as follows:
[0016] (1) This utility model uses the combination of connecting rod and plug rod. First, multiple heat exchange plates are placed between fixed plate one and fixed plate two. Then, the plug rod is pulled and one end of the connecting rod is connected to fixed plate two. At this time, the plug rod is stopped and the plug rod moves towards the connecting rod until one end of the plug rod is inserted into the plug hole. This achieves the fixed connection between fixed plate one and fixed plate two. When disassembling, only the plug rod needs to be pulled to separate one end from the plug hole to achieve quick disassembly of the heat exchange plates.
[0017] (2) By using the rotating plate and locking block together, after the heat exchange fins are installed, the connecting pipe and the pipeline are fixedly connected by the flange. At this time, the rotating plate is pulled to rotate until the locking block abuts against the flange. At this time, the rotating plate is located on one side of the plug rod and abuts against the end of the plug rod away from the connecting rod, thereby locking the plug rod and ensuring its stability. At the same time, the locking block applies pressure to the connection of the connecting pipe, which effectively improves the stability of the connecting pipe during operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: This example addresses the problem that in the prior art, plate heat exchangers are typically fixed with bolts during use. If maintenance or cleaning is required, the disassembly and assembly process is complex and time-consuming, leading to prolonged equipment downtime and affecting production efficiency. In other words, it is difficult to achieve rapid installation and removal of heat exchange plates.
[0027] Please see Figure 1 - Figure 3 As shown, this embodiment is a plate heat exchanger based on quick assembly and disassembly, including a first fixed plate 1 and a second fixed plate 101. Multiple heat exchange plates 102 are fixedly installed between the first fixed plate 1 and the second fixed plate 101. Connecting pipes 103 are fixedly installed on both the first fixed plate 1 and the second fixed plate 101.
[0028] A disassembly assembly 2 is fixedly installed on the second fixed plate 101. The disassembly assembly 2 includes a connecting rod 201 and a plug rod 202. One end of the connecting rod 201 is fixedly connected to the first fixed plate 1, and the plug rod 202 is movably installed on the second fixed plate 101. A plug hole 204 is opened on the connecting rod 201, and one end of the plug rod 202 is located in the plug hole 204.
[0029] A fixing tube 206 is fixedly installed on the fixing plate 101. The insertion rod 202 is movably installed in the fixing tube 206. A reset plate 207 is movably installed in the fixing tube 206. The reset plate 207 is fixedly connected to the insertion rod 202. A spring is fixedly installed on one side of the reset plate 207. The end of the spring away from the reset plate 207 is fixedly connected to the fixing tube 206. In actual use, under the action of the spring, one end of the insertion rod 202 is inserted into the insertion hole 204, thereby fixing the connecting rod 201. When it is necessary to disassemble the heat exchange plate 102, only the insertion rod 202 needs to be pulled. At this time, the reset plate 207 moves, and the spring gradually compresses and contracts until the insertion rod 202 separates from the insertion hole 204. At this time, the fixing plate 1 and the fixing plate 201 separate.
[0030] First, place multiple heat exchange plates 102 between the first fixing plate 1 and the second fixing plate 101. Then, pull the insertion rod 202 and connect one end of the connecting rod 201 to the second fixing plate 101. At this point, stop pulling the insertion rod 202, and the insertion rod 202 moves towards the connecting rod 201 until one end of the insertion rod 202 is inserted into the insertion hole 204. This achieves a fixed connection between the first fixing plate 1 and the second fixing plate 101. When disassembling, simply pull the insertion rod 202 to separate one end from the insertion hole 204, and the heat exchange plates 102 can be quickly disassembled.
[0031] Example 2: This example addresses the issue that, due to the lack of a stable structure, the pipeline may vibrate during fluid flow, potentially leading to leaks at the pipeline joints over time. This can result in the loss of hot or cold fluid, affecting heat exchange efficiency and potentially causing more serious safety issues, namely, the difficulty in ensuring the stability of the pipeline during operation.
[0032] Please see Figure 4 - Figure 5 As shown, this utility model also includes a rotating plate 203, which is movably mounted on a fixed plate 101. The rotating plate 203 is located on one side of the insertion rod 202. A locking block 205 is fixedly mounted on the rotating plate 203. A groove is provided on the fixed plate 101, and the rotating plate 203 is engaged in the groove. That is, in the initial state, the rotating plate 203 is located in the groove. After the fixed plate 1 and the fixed plate 101 are fixedly connected and the connecting pipe 103 is connected, the rotating plate 203 is pulled to make it rotate until the locking block 205 abuts against the flange on the connecting pipe 103. This ensures the stability of the connecting pipe 103 during use and applies a certain pressure to the flange, effectively improving the sealing performance of the flange.
[0033] Multiple connecting pipes 103 are provided, as are multiple fixed pipes 206 and rotating plates 203. The rotating plate 203 is located above the connecting pipes 103. Support blocks 208 are fixedly installed on the side of fixed plate 1 and fixed plate 2 101 away from the heat exchange plate 102. The support blocks 208 are located at the bottom of fixed plate 1 and fixed plate 2, and the stability of fixed plate 1 and fixed plate 2 101 is ensured by the support blocks 208.
[0034] After the heat exchanger fins 102 are installed, the connecting pipe 103 is fixedly connected to the pipeline through a flange. At this time, the rotating plate 203 is pulled to rotate until the locking block 205 abuts against the flange. At this time, the rotating plate 203 is located on one side of the insertion rod 202 and abuts against the end of the insertion rod 202 away from the connecting rod 201, thereby locking the insertion rod 202 and ensuring its stability. At the same time, the locking block 205 applies pressure to the connection of the connecting pipe 103, effectively improving the stability of the connecting pipe 103 during operation.
[0035] Combining Embodiment 1 and Embodiment 2, the fixed plate 1 and the fixed plate 201 are fixedly connected by the cooperation of the insertion rod 202 and the insertion hole 204. During disassembly, only the insertion rod 202 needs to be pulled to separate one end from the insertion hole 204, which can quickly disassemble the heat exchange plate 102. After the heat exchange plate 102 is installed, the connecting pipe 103 is fixedly connected to the pipeline through the flange. At this time, the rotating plate 203 is pulled to rotate until the locking block 205 abuts against the flange. At this time, the rotating plate 203 is located on one side of the insertion rod 202 and abuts against the end of the insertion rod 202 away from the connecting rod 201, thereby locking the insertion rod 202 and ensuring its stability. At the same time, the locking block 205 applies pressure to the connection of the connecting pipe 103, which effectively improves the stability of the connecting pipe 103 during operation.
[0036] The working process and principle of this utility model are as follows:
[0037] First, the fixed plate 1 and the fixed plate 201 are fixedly connected by the use of the plug rod 202 and the socket 204. When disassembling, simply pull the plug rod 202 to separate one end from the socket 204 to quickly disassemble the heat exchange plate 102.
[0038] Furthermore, after the heat exchanger 102 is installed, the connecting pipe 103 is fixedly connected to the pipeline through a flange. At this time, the rotating plate 203 is pulled to rotate until the locking block 205 abuts against the flange. At this time, the rotating plate 203 is located on one side of the insertion rod 202 and abuts against the end of the insertion rod 202 away from the connecting rod 201, thereby locking the insertion rod 202 and ensuring its stability. At the same time, the locking block 205 applies pressure to the connection of the connecting pipe 103, effectively improving the stability of the connecting pipe 103 during operation.
[0039] In other words, the present invention, through the disassembly and assembly component 2, not only enables the heat exchange fins 102 to be quickly installed and disassembled, but also effectively improves the stability of the connecting pipe 103 during operation.
