Description

Technical Field

[0001] This utility model relates to the field of heat exchanger flange technology, and in particular to a heat exchanger flange with a flow guide groove. Background Technology

[0002] A heat exchanger flange is a device component used in heat exchangers to connect and guide fluid flow. The flange itself is usually a circular metal disc used to connect two pipes or devices, while the flow guide groove design adds flow guide grooves to the flange surface to optimize the flow direction and velocity of the fluid.

[0003] Utility model patent CN221055615U discloses a plate heat exchanger bushing flange. Its key technical features include a flange sleeve and a connecting device. The flange sleeve comprises a flange bushing and a rubber sleeve, with the flange bushing and rubber sleeve fixedly connected. This utility model, through the arrangement of structural components such as a flange sleeve, flange bushing, rubber sleeve, connecting device, connecting ring, heat exchanger connector, and fixing blocks, allows the flange sleeve to be used in conjunction with the heat exchanger. A positioning assembly allows two positioning blocks to move into the connecting ring, assembling and fixing the flange sleeve with the connecting device. A moving assembly allows the two positioning blocks to move out of the connection, enabling disassembly and separation of the flange sleeve from the connecting device. This achieves the effect of facilitating manual fixing and separation of the flange bushing from the heat exchanger connector, solving the problem of not being able to quickly and manually assemble and disassemble the bushing flange and heat exchanger without the need for tools.

[0004] Regarding the above-mentioned content, the following technical defects exist: A heat exchanger flange with a flow guide groove has a flow guide plate installed inside the flange. A flange is a device component used in heat exchangers to connect and guide fluid flow. A flange with a flow guide groove can optimize the fluid velocity. However, the flow guide velocity of the flow guide groove on the flange cannot be adjusted. Since some equipment operates at low load for most of the time, the inability to adjust the size of the flow guide groove will cause the entire heat exchanger to be in a high-velocity state for extended periods. This leads to excessive energy transfer and energy waste. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the flow velocity of the guide groove on the flange guide plate cannot be adjusted, and some equipment operates at low load for most of the time. The inability to adjust the size of the flow groove will cause the entire heat exchanger to be in a high flow velocity state for a long time, which will lead to excessive energy transfer and energy waste.

[0006] To solve the above-mentioned technical problems, this utility model provides a heat exchanger flange with a guide groove, comprising: a flange body, a guide plate installed on the inner wall of the flange body, an adjustment mechanism provided on one side of the guide plate, the adjustment mechanism including a fixed frame, the fixed frame being fixedly connected to one side of the guide plate, an adjustment plate being slidably connected to the inner wall of the fixed frame, and limit rods being slidably connected to both sides of the adjustment plate, one end of the arc surface of the limit rod being fixedly connected to the guide plate, a rotating rod rotatably passing through the inner wall of one of the limit rods, both ends of the arc surface of the rotating rod being fitted with coil springs, the two ends of the arc surface of the coil springs being fixedly connected to the arc surfaces of the rotating rod and the limit rod respectively, a connecting ring being fixedly connected to the arc surface of the rotating rod, an abutment rod being fixedly connected to one end of the arc surface of the connecting ring, a fixed rod being engaged on one side of the abutment rod, one end of the arc surface of the fixed rod being fixedly connected to one side of the adjustment plate, and a connecting rod being fixedly connected to the other end of the arc surface of the connecting ring.

[0007] The effects achieved by the above components are as follows: The heat exchanger flange body with guide grooves has guide plates installed inside its flange body. The flange body is a device component used in heat exchangers to connect and guide fluid flow. The flange body with guide grooves can optimize the fluid flow rate. However, the guide speed of the guide grooves on the guide plate of this flange body cannot be adjusted. Some equipment operates at low load for most of the time during operation. Without the ability to adjust the size of the flow grooves, the entire heat exchanger will be in a high flow rate state for a long time, which will lead to excessive energy transfer and energy waste. At this time, the size of the guide grooves on the guide plate can be adjusted by the adjustment mechanism. When the equipment does not require excessively high flow rates, the overall performance of the flange body can be improved by adjustment, the flow efficiency can be improved, and energy waste can be reduced.

[0008] Preferably, a connecting plate is fixedly connected to the side wall of the limiting rod, and the inner wall of the connecting plate is slidably connected to the arc surface of the connecting rod.

[0009] The effect achieved by the above components is that the connecting plate can improve the stability of the connecting rod on the inner wall of the limiting rod.

[0014] Preferably, the cross-section of one end of the abutment rod is arc-shaped.

[0015] The effect achieved by the above components is that the arc-shaped abutment rod has good locking stability when it comes into contact with the fixed rod.

[0016] Preferably, an auxiliary mechanism is provided on one side of the guide plate. The auxiliary mechanism includes a limiting frame, which is fixedly connected to one side of the guide plate.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 7 The present invention provides a heat exchanger flange with a flow guide groove, comprising: a flange body 1, a flow guide plate 4 installed on the inner wall of the flange body 1, an adjustment mechanism 2 on one side of the flow guide plate 4, and an auxiliary mechanism 3 on one side of the flow guide plate 4.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 5 The adjusting mechanism 2 includes a fixed frame 201, which is fixedly connected to one side of the guide plate 4. An adjusting plate 202 is slidably connected to the inner wall of the fixed frame 201. Limiting rods 203 are slidably connected to both sides of the adjusting plate 202. One end of the arc surface of the limiting rod 203 is fixedly connected to the guide plate 4. A rotating rod 204 rotatably passes through the inner wall of one of the limiting rods 203. A coil spring 205 is sleeved on both ends of the arc surface of the rotating rod 204. The two ends of the arc surface of the coil spring 205 are fixedly connected to the arc surfaces of the rotating rod 204 and the limiting rod 203, respectively. A connecting ring 206 is fixedly connected to the arc surface of the rotating rod 204. One end of the arc surface of the connecting ring 206 is fixedly connected to an abutment rod 207. A fixing rod 208 is snapped onto one side of the abutment rod 207. One end of the arc surface of the fixing rod 208 is fixedly connected to one side of the adjusting plate 202. The other end of the arc surface of the connecting ring 206 is fixedly connected to a connecting rod 209. The heat exchanger flange body 1 with a guide groove has the guide plate 4 installed inside it. The flange body 1 is a device component used to connect and guide fluid flow in a heat exchanger. The flange body 1 with a guide groove can optimize the fluid flow rate. However, the guide speed of the guide groove on the guide plate 4 of the flange body 1 cannot be adjusted. Some equipment may experience problems during operation. Most of the time, the heat exchanger operates under low load, and the size of the flow channel cannot be adjusted. This results in the entire heat exchanger being in a high flow rate state for a long time, leading to excessive energy transfer and energy waste. The size of the flow channel on the guide plate 4 can be adjusted using the adjustment mechanism 2. When the equipment does not require excessively high flow rates, this adjustment can improve the overall performance of the flange body 1, enhance flow efficiency, and reduce energy waste. A connecting plate 210 is fixedly connected to the side wall of the limit rod 203. The inner wall of the connecting plate 210 is slidably connected to the arc surface of the connecting rod 209. The connecting plate 210 can raise the connecting rod... The stability of the inner wall of the limiting rod 203 is improved by the following: one end of the arc surface of the connecting rod 209 is fixedly connected to the pressing rod 212, which has a circular cross-section. The pressing rod 212 can increase the speed when pressing the connecting rod 209. Two guide rods 211 slide through the inner wall of the adjusting plate 202. One end of the arc surface of the guide rod 211 is fixedly connected to the side wall of the fixed frame 201. The guide rod 211 can improve the stability of the adjusting plate 202 sliding in the fixed frame 201. One end of the side of the abutment rod 207 has an arc-shaped cross-section. When the arc-shaped abutment rod 207 comes into contact with the fixed rod 208, the locking stability is better.

[0035] In the embodiments of this utility model, please refer to Figure 6 and Figure 7The auxiliary mechanism 3 includes a limiting frame 31, which is fixedly connected to one side of the guide plate 4. Two connecting holes 32 are provided on the arc surface of the limiting frame 31. Two moving plates 33 are slidably connected to the arc surface of the limiting frame 31. Electric push rods 34 are fixedly connected to both sides of the inner wall of the limiting frame 31. A fixing block 35 is fixedly connected to the output end of the electric push rod 34. A power rod 36 is fixedly connected to one side of the fixing block 35 near the side of the electric push rod 34. The power rod 36 slides through the inner wall of the limiting frame 31. The two power rods 36 are respectively fixedly connected to one side of the two moving plates 33. A [missing information - likely a device or mechanism] is fixedly connected to the side of the two moving plates 33 away from the power rod 36. When the heat exchanger flange body 1 and the pipe flange body 1 are connected by the same sealing gasket 37, and the heat exchanger flange body 1 and the pipe flange body 1 are transported to overheated cooling water for a long time, the sealing performance between the two flange bodies 1 can be improved by the auxiliary mechanism 3. This prevents the sealing performance between the two flange bodies 1 from decreasing due to the high temperature of the cooling water. Adjusting plates 38 are fixedly connected to both ends of the side of the sealing gasket 37. The adjusting plates 38 are elastic plates. The adjusting plates 38 can drive the sealing gasket 37 into the connection hole 32, thereby improving the stability of the sealing gasket 37 in the connection hole 32.

[0036] The working principle of the heat exchanger flange with guide groove provided by this utility model is as follows: When it is necessary to adjust the size of the guide groove on the guide plate 4, press the connecting rod 209. The movement of the connecting rod 209 will drive the rotating rod 204 to rotate within the limiting rod 203 through the connecting ring 206. At this time, the coil spring 205 will be deformed, and the abutment rod 207 will slide out from the slot of the fixed rod 208. At this time, the adjusting plate 202 can be driven to slide within the fixed frame 201 through the fixed rod 208. The sliding of the adjusting plate 202 will be driven by... The fixed frame 201 covers the guide groove on the guide plate 4 to achieve the adjustment effect. The size of the guide groove is adjusted to a suitable position by adjusting the plate 202. At this time, the connecting rod 209 can be loosened. The coil spring 205 installed on the rotating rod 204 will reset and drive the rotating rod 204 and the connecting ring 206 to move. At this time, the abutment rod 207 can be driven to contact the slot on the fixed rod 208 again. At this time, the position of the fixed rod 208 after adjustment can be fixed. At this time, the angle adjusted by the adjusting plate 202 can be fixed in the adjusting frame.

[0037] When it is necessary to improve the sealing performance of the connection between the two flange bodies 1, the electric actuator 34 installed on the limit frame 31 is activated. The movement of the electric actuator 34 can drive the power rod 36 to slide within the limit frame 31 through the fixed block 35. This allows the power rod 36 to drive the moving plate 33 to move away from the limit frame 31. The moving plate 33 can drive the sealing gasket 37 to move, and the sealing gasket 37 located in the connection hole 32 will be pulled out. At this time, the sealing gasket 37 will contact the connection between the two flange bodies 1, thereby improving the sealing effect between the two flange bodies 1 under the pressure of the moving plate 33.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
