Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a heat exchanger that can be used with multiple media. Background Technology

[0002] A heat exchanger, also known as a heat transfer device, is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also one of the key devices for improving energy efficiency. However, many existing heat exchangers suffer from a single media channel, making them unable to meet the demands of simultaneous heat exchange with multiple media in complex processes. Utility Model Content

[0003] This invention addresses the problems mentioned above by designing a heat exchanger that can be used with multiple media, thereby increasing the channels for fluid media and enabling simultaneous heat exchange with multiple media.

[0004] To achieve the above objectives, this utility model provides a heat exchanger applicable to multiple media, comprising a cylinder, a flange, a spiral tube assembly, and a jacket layer. The hollow cylinder is fixedly connected to the flange at one end, and the flange is bolted to a retaining ring. A sealing gasket is installed between the flange and the retaining ring. The spiral tube assembly is fixedly installed in the cavity of the cylinder by pipe clamps. The jacket layer is fixedly connected to the outer wall of the cylinder. The cylinder has a heat exchanger inlet and outlet that are connected, and a temperature measuring port is provided at the bottom of the cylinder. The jacket layer has a fluid inlet and a fluid outlet that are connected.

[0005] Furthermore, the spiral tube assembly includes two interlaced spiral tubes with their fluid inlets facing away from each other.

[0006] Furthermore, a cleaning mechanism is provided inside the water outlet pipe of the jacket layer.

[0007] Furthermore, the cleaning mechanism includes fixing clips, a rotating shaft, and spiral blades. There are multiple sets of fixing clips arranged in a linear array inside the water outlet pipe. The rotating shaft is rotatably disposed between the fixing clips, and the spiral blades are fixedly connected to the rotating shaft.

[0008] Furthermore, the fixing clip includes an outer ring, an inner ring, and connecting ribs. The outer ring is fixedly connected to the inner wall of the water outlet pipe. The inner ring is concentrically arranged with the outer ring. The rotating shaft is clearance-fitted and rotatably connected to the inner ring. There are multiple sets of connecting ribs arranged in a circumferential array between the outer ring and the inner ring.

[0009] Furthermore, the rotating shaft is provided with multiple diameter-changing sections, which are engaged with the inner ring.

[0010] Preferably, the diameter of the variable diameter section is larger than the inner diameter of the inner ring.

[0011] Furthermore, the jacket layer is fixedly connected to an ear-type support, the rotating shaft is fixedly connected to a connecting shaft via a coupling, and a driving component is provided on the ear-type support, the driving component driving the connecting shaft.

[0012] Furthermore, the drive assembly includes a power source, a drive sprocket, a driven sprocket, and a chain. The output shaft of the power source drives and connects to the drive sprocket. The driven sprocket is sleeved on the connecting shaft, and the chain is hung between the drive sprocket and the driven sprocket.

[0013] Furthermore, an L-shaped protective plate is fixedly connected to the outer wall of the jacket layer, the connecting shaft is rotatably connected to the protective plate through a bearing seat, and the driven sprocket and the water outlet pipe are respectively arranged on both sides of the protective plate.

[0014] In summary, this utility model has the following advantages and beneficial technical effects: 1. This utility model features multiple interlaced spiral tubes and a jacket layer, enabling it to be applied to three or fewer media, thereby improving the heat exchange range and efficiency. The inclusion of a temperature measuring port facilitates temperature measurement by workers using a thermometer, allowing them to obtain temperature data at any time.

[0015] 2. In this utility model, the cleaning mechanism is installed inside the water outlet pipe. It uses the impact force of the fluid medium to drive the spiral blades to rotate. First, it activates the turbulence mechanism inside the water outlet pipe, enhancing the mixing and heat exchange effect of the fluid. Second, it uses the rotating and pushing action of the spiral blades to push the impurities deposited inside the water outlet pipe to the outside of the pipe, effectively reducing the blockage rate of the water outlet pipe.

[0016] 3. The fixing clip in this utility model includes an outer ring, an inner ring, and a connecting rib, which together form a hollow structure. This structure increases the flow rate of the fluid medium while providing stable support for the rotating shaft, and reduces the impact area and stress of the fluid. The variable diameter design of the rotating shaft restricts the axial position of the shaft and the inner ring assembly, preventing the shaft from dislodging from the inner ring due to fluid impact.

[0017] 4. The middle ear type support of this utility model is used to install the drive component. The drive component provides additional power for the rotation of the spiral blade. The power source outputs power and transmits the power to the connecting shaft fixedly connected to the rotating shaft through the chain drive system, which ultimately drives the spiral blade to rotate synchronously.

[0018] 5. The protective plate in this utility model provides support for the rotation of the connecting shaft, allowing the connecting shaft to be supported outside the jacket layer by the protective plate with bearing seat. On the other hand, it separates the driven sprocket and the water outlet pipe, reducing the contamination of the driven sprocket transmission surface by impurities in the fluid.

[0021] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail as follows: like Figures 1-2 As shown, this embodiment discloses a multi-media heat exchanger, including a cylinder 1, a flange 11, a spiral tube assembly 2, and a jacket layer 3. The upper end of the hollow cylinder 1 is welded with a flange 11, and a retaining ring 4 is fixedly connected to the flange 11 by bolts. A sealing gasket is installed between the retaining ring 4 and the flange 11. The spiral tube assembly 2 is fixedly installed in the cavity of the cylinder 1 by pipe clamps. The jacket layer 3 is welded and fixed to the outer wall of the cylinder 1. The cylinder 1 has a heat exchanger inlet 12 and a heat exchanger outlet 13 that are connected, and a temperature measuring port 14 is opened at the bottom of the cylinder 1. The jacket layer 3 has a fluid inlet 31 and a fluid outlet 32 ​​that are connected. The spiral tube assembly 2 includes two interlaced spiral tubes, and the fluid inlets 31 of the two spiral tubes are arranged opposite to each other.

[0022] like Figures 2-3 As shown, a cleaning mechanism 5 is installed inside the water outlet pipe 33 of the jacket layer 3. The cleaning mechanism 5 includes a fixing clip 51, a rotating shaft 52, and a spiral blade 53. In this embodiment, there are two sets of fixing clips 51, which are respectively set at the two ends of the water outlet pipe 33. The rotating shaft 52 is rotatably set between the two sets of fixing clips 51, and the spiral blade 53 is fixedly connected to the rotating shaft 52.

[0023] like Figures 5-6 As shown, the fixing clip 51 includes an outer ring 511, an inner ring 512, and connecting ribs 513. The outer wall of the outer ring 511 is fixedly connected to the inner wall of the water outlet pipe 33. The inner ring 512 is concentrically arranged with the outer ring 511. The rotating shaft 52 is intermittently engaged and rotatably connected to the inner ring 512. In this embodiment, there are three sets of connecting ribs 513, arranged in a circumferential array between the inner wall of the outer ring 511 and the outer wall of the inner ring 512. The rotating shaft 52 is provided with multiple diameter-changing parts 521, which engage with the inner ring 512 axially. The diameter of the diameter-changing part 521 is larger than the inner diameter of the inner ring 512.

[0024] like Figure 2 as well as Figure 4 As shown, an ear-type support 34 is welded to the outer wall of the jacket layer 3. A connecting shaft 6 is fixedly connected to the rotating shaft 52 via a coupling. A drive assembly 7 is installed on the ear-type support 34, and the drive assembly 7 indirectly drives the connecting shaft 6. The drive assembly 7 includes a power source 71, a drive sprocket 72, a driven sprocket 73, and a chain 74. The power source 71 is an electric motor. The housing of the electric motor is fixedly connected to the ear-type support 34 by screws, and the output shaft drives the drive sprocket 72. The driven sprocket 73 is sleeved on the connecting shaft 6, and the chain 74 is hung between the drive sprocket 72 and the driven sprocket 73. An L-shaped protective plate 35 is welded to the outer wall of the jacket layer 3. The connecting shaft 6 is rotatably connected to the protective plate 35 via a bearing seat. A sealing gasket is installed between the bearing seat and the protective plate 35. The driven sprocket 73 and the water outlet pipe 33 are respectively located on both sides of the protective plate 35.

[0025] The working principle of a multi-media heat exchanger according to this utility model is as follows: When the heat exchanger is in use, the fluid medium enters from the fluid inlet 31 of the spiral tube group 2 and the jacket layer 3 respectively, and the heat exchanger flows from the heat exchanger inlet 12 of the cylinder 1 to the heat exchanger outlet 13. After the heat exchange of the fluid medium by the heat exchanger, it finally flows out from the fluid outlet 32.

[0026] The spiral blades 53 of the outlet pipe 33 are driven to rotate by the fluid stress of the medium inside the jacket layer 3, thereby achieving turbulent flow of the medium inside the outlet pipe 33. At the same time, impurities deposited inside the outlet pipe 33 are pushed out of the pipe by the spiral blades 53. The drive assembly 7 provides additional power for the rotation of the spiral blades 53. When the power source 71 is started, the motor output shaft drives the drive sprocket 72 to rotate, and then transmits the power to the driven sprocket 73 through the chain 74. The connecting shaft 6 and the rotating shaft 52 rotate synchronously with the driven sprocket 73, ultimately driving the spiral blades 53 to work.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
