Description

Technical Field

[0001] This utility model relates to the field of counterflow heat exchanger technology, specifically a multi-channel counterflow heat exchanger. Background Technology

[0002] A counter-flow heat exchanger is a highly efficient heat exchange device. Its core characteristic is that the cold and hot fluids flow in opposite directions. The structure of a counter-flow heat exchanger typically includes a core, within which multiple jacketed flow channels are arranged sequentially from bottom to top. Adjacent jacketed flow channels are separated by heat transfer baffles, and fins are installed between these baffles. These fins further divide the jacketed flow channels into multiple channels, thereby increasing the heat exchange area and efficiency.

[0003] A search revealed, for example, patent application number CN202323270246.4, which relates to the field of heat exchanger technology. It discloses a counter-current heat exchanger. Compared to existing technologies, this counter-current heat exchanger, through baffles, can extend the flow path of the heat exchange medium, improving heat exchange efficiency. When the baffles change the flow direction of the heat exchange medium, a protective plate protects the inner wall of the shell-side cylinder, reducing the impact on the inner wall of the shell-side cylinder. The protective plate is slidably connected to the shell-side cylinder through connecting rods, sealing rings, and tension springs. When the protective plate is impacted, the tension springs can be stretched to buffer the impact, thus achieving the purpose of safe protection for the protective plate and extending its service life. During use, because the liquid and heat exchange fluid cannot simultaneously extend their flow paths within the counter-current heat exchanger body, the liquid heat exchange effect is poor.

[0004] Further searching, for example, patent application number CN202022668527.5, reveals that this utility model provides a counter-current heat exchanger, including a heat exchanger shell. This utility model can effectively increase the heat exchange efficiency of the heat exchanger, save energy, and facilitate the installation and replacement of sterilization devices. During use, because the liquid and heat exchange fluid cannot simultaneously extend the flow path of the heat exchange fluid and liquid in the counter-current heat exchanger body when they flow in the counter-current heat exchanger, the liquid heat exchange effect is poor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-channel counter-current heat exchanger, which solves the problem that when liquid and heat exchange fluid flow in a counter-current heat exchanger, the flow paths of the heat exchange fluid and liquid in the counter-current body become longer, resulting in poor liquid heat exchange effect.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-channel countercurrent heat exchanger, including a countercurrent body, an extension mechanism is provided inside the countercurrent body, the extension mechanism extends to the outside of the countercurrent body, an input pipe is provided at one end of the countercurrent body, and an output pipe is provided at the other end of the countercurrent body, and a threaded rod is provided on the front side of the countercurrent body.

[0007] The extension mechanism includes a metal hose and a pipe, the metal hose being fixedly connected to the pipe. An extension plate is provided inside the counterflow device body. An adjustment plate is provided at one end of the extension plate away from the inner wall of the counterflow device body. One end of the adjustment plate extends into the interior of the extension plate and contacts the extension plate. Movable plates are provided at the top and bottom of the counterflow device body. A round rod is provided on the movable plate near the counterflow device body. The round rod extends into the interior of the counterflow device body and is fixedly connected to the adjustment plate.

[0008] Preferably, the top surface of the counterflow device body is provided with an inlet pipe and the bottom surface of the counterflow device body is provided with an outlet pipe, which connects the heat exchange fluid transport pipeline outside the inlet pipe and the outlet pipe, and connects the inlet pipe and the outlet pipe to the external heat exchange medium transport pipeline.

[0009] Preferably, the threads on the top and bottom surfaces of the threaded rod are arranged in opposite directions. The threaded rod passes through the moving plate and is threadedly connected to the moving plate. The rotation of the threaded rod can reduce the distance between the two moving plates, and the round rod connected to the moving plate moves simultaneously.

[0010] Preferably, a fixing plate is fixedly installed inside both ends of the counterflow device body, and the pipe passes through the fixing plate, and there are multiple pipes.

[0011] Preferably, a filter plate is provided inside the liquid inlet pipe, the filter plate is in contact with the liquid inlet pipe, and connecting rods are fixedly provided on both sides of the filter plate. When the connecting rods move upward, the filter plate fixedly connected to the connecting rods moves upward at the same time, so that the connecting rods gradually separate from the groove.

[0012] Preferably, the inner walls on both sides of the liquid inlet pipe are provided with grooves, and the connecting rod is located inside the grooves.

[0013] Preferably, brackets are provided on both sides of the top end of the liquid inlet pipe, and mounting screws are provided on one side of the top end of the brackets. The brackets are fixedly connected to the connecting rods by the mounting screws, so that the filter plate is stably placed in the liquid inlet pipe. Beneficial effects

[0014] This invention provides a multi-channel counter-current heat exchanger. Compared with the prior art, it has the following advantages:

[0015] 1. This multi-channel counter-current heat exchanger features a threaded rod with opposite threads on its top and bottom surfaces. The threaded rod passes through and is threadedly connected to the moving plate. Rotation of the threaded rod reduces the distance between the two moving plates, causing the regulating plate to move and pushing the metal hose to move. This causes the metal hose to deform and bend, extending the time the heat exchange fluid spends in the liquid as it flows through the pipes and metal hose. Furthermore, the movement of the regulating plate reduces the distance between it and the inner wall of the counter-current exchanger body, lengthening the flow path of the liquid and heat exchange fluid as the liquid moves from right to left within the counter-current exchanger body, thus improving heat exchange efficiency. This process is simple and quick.

[0016] 2. This multi-channel countercurrent heat exchanger can perform filtration through the filter plate in the liquid inlet pipe to reduce impurities in the liquid. The filter plate, which is fixedly connected by the connecting rod, moves upward at the same time, so that the connecting rod gradually separates from the groove. After separation, the filter plate is no longer located inside the liquid inlet pipe. The filter plate can be removed and cleaned to reduce surface impurities and facilitate subsequent use.

Detailed Implementation

[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. 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.

[0023] Please see Figure 1-2 This utility model provides a technical solution: a multi-channel countercurrent heat exchanger, including a countercurrent body 1, an extension mechanism 2 is provided inside the countercurrent body 1, the extension mechanism 2 extends to the outside of the countercurrent body 1, an input pipe 3 is provided at one end of the countercurrent body 1, and an output pipe 4 is provided at the other end of the countercurrent body 1, and a threaded rod 7 is provided on the front side of the countercurrent body 1.

[0024] The extension mechanism 2 includes a metal hose 201 and a pipe 202. The metal hose 201 is fixedly connected to the pipe 202. An extension plate 203 is provided inside the counterflow body 1. An adjustment plate 204 is provided at one end of the extension plate 203 away from the inner wall of the counterflow body 1. One end of the adjustment plate 204 extends into the interior of the extension plate 203 and contacts the extension plate 203. Motion plates 205 are provided at the top and bottom of the counterflow body 1. A round rod 206 is provided near the counterflow body 1 on the motion plate 205. The round rod 206 extends into the interior of the counterflow body 1 and is fixedly connected to the adjustment plate 204.

[0025] The top surface of the counterflow device body 1 is provided with an inlet pipe 5, and the bottom surface of the counterflow device body 1 is provided with an outlet pipe 6. The threads on the top and bottom surfaces of the threaded rod 7 are arranged in opposite directions. The threaded rod 7 passes through the moving plate 205 and is threadedly connected to the moving plate 205. Fixed plates 207 are fixedly installed inside both ends of the counterflow device body 1. Pipes 202 pass through the fixed plates 207. There are multiple pipes 202.

[0026] Please see Figure 1 and 3 -4. A filter plate 208 is installed inside the liquid inlet pipe 5. The filter plate 208 is in contact with the liquid inlet pipe 5. Connecting rods 209 are fixedly installed on both sides of the filter plate 208. The inner walls of both sides of the liquid inlet pipe 5 are provided with grooves 210. The connecting rods 209 are located inside the grooves 210. Supports 211 are installed on both sides of the top end of the liquid inlet pipe 5. A mounting screw 212 is installed on one side of the top end of the support 211. The support 211 is fixedly connected to the connecting rods 209 by the mounting screws 212.

[0027] During operation, the heat exchange fluid delivery pipe 202 outside the input pipe 3 and output pipe 4 is connected, and the liquid inlet pipe 5 and liquid outlet pipe 6 are connected to the external heat exchange medium delivery pipe 202. The heat exchange fluid enters the countercurrent unit body 1 from the input pipe 3, and the metal hose 201 and pipe 202 are connected together, allowing the heat exchange fluid in the input pipe 3 to be delivered through pipe 202. One end of the heat exchange fluid can move from left to right and be released on the right side, and then be released through the output pipe 4. After that, the heat exchange liquid enters the liquid inlet pipe 5 and passes through the liquid inlet pipe 5. The filter plate 208 performs filtration, reducing impurities in the liquid. When cleaning the filter plate 208, first remove the mounting screw 212, ensuring one end of the screw is no longer in contact with the connecting rod 209, thus separating the screw 212 from the connecting rod 209. After separation, move the connecting rod 209 upwards, and simultaneously move the filter plate 208, which is fixedly connected to the connecting rod 209, upwards, gradually separating the connecting rod 209 from the groove 210. After separation, the filter plate 208 is no longer located inside the inlet pipe 5. Remove the filter plate 208. The surface is cleaned to reduce impurities and facilitate subsequent use. The threaded rod 7 is rotated. Since the top and bottom threads of the threaded rod 7 are oppositely arranged, the threaded rod 7 passes through and is threadedly connected to the moving plate 205. Rotation of the threaded rod 7 reduces the distance between the two moving plates 205, and the round rod 206 connected to the moving plate 205 moves simultaneously. Because the moving rod is movably connected to both the countercurrent unit body 1 and the extension plate 203, the movement of the round rod 206 is guaranteed. Since the round rod 206 is fixedly connected to the adjusting plate 204... The regulating plate 204 is movably connected to the extension plate 203. The movement of the round rod 206 can move the regulating plate 204 and push the metal hose 201 to move, causing the metal hose 201 to deform. This allows the heat exchange fluid to stay in the liquid for a longer time when flowing through the pipe 202 and the metal hose 201. Furthermore, the movement of the regulating plate 204 reduces the distance between the regulating plate 204 and the inner wall of the counterflow body 1, making the liquid flow path longer when it moves from right to left in the counterflow body 1, thus improving the heat exchange efficiency.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
