Description

Technical Field

[0001] This application relates to the field of flanges, and more particularly to a flange heating jacket. Background Technology

[0002] Melt conveying is a key piece of equipment in polyester plants, primarily responsible for transporting solutions or melts and maintaining them at a certain temperature, especially for high-temperature melts. However, due to the long conveying pipelines and bends, flanges are required for connection. To maintain a certain temperature on the flanges and prevent the melt from cooling and solidifying, flange heating jackets are needed to heat the flanges.

[0003] Existing flange heating jackets heat the flange by covering it, but during the heating process, the upper and lower surfaces of the flange dissipate heat too quickly, which can cause low temperatures at the pipe connection points and localized cold spots, thus reducing the applicability of the system. Utility Model Content

[0004] To address the aforementioned problems, this application provides a flange heating jacket.

[0005] The flange heating jacket provided in this application adopts the following technical solution:

[0006] A flange heating jacket includes two arc-shaped clamps. A heating plate is fixedly connected to one side wall of the two arc-shaped clamps facing each other. One end of the two arc-shaped clamps is hinged together. The two arc-shaped clamps are provided with a fixing component for installation and a sealing component for preventing heat loss. The sealing component includes multiple elastic sealing gaskets fixedly connected to the inner side wall of the arc-shaped clamps on both sides of the heating plate. A fixing plate is fixedly connected to the side wall of each end of the arc-shaped clamps. One side wall of the fixing plate is fixedly connected to the elastic sealing gasket. An elastic connecting plate is provided between every two fixing plates. The two ends of the elastic connecting plate pass through the fixing plate and are slidably configured. One side wall of the elastic connecting plate is fixedly connected to the elastic sealing gasket. A connecting component is provided on the elastic connecting plate.

[0007] By adopting the above technical solution, during use, two arc-shaped clamps are swung and placed on the flange. Then, the two arc-shaped clamps are connected and fixed by a fixing assembly, so that the heating plate contacts the flange and heats the flange. When the two arc-shaped clamps are fixed, the elastic sealing gasket contacts and squeezes the pipe, causing the elastic connecting plate to bend and slide at both ends in the fixing plate. Then, multiple elastic connecting plates are connected by a connecting assembly, so that the elastic sealing gasket wraps around the pipe and the flange. This minimizes the problem of low temperature at the pipe connection point and local cold spots caused by excessive heat dissipation on the upper and lower sides of the flange during heating, which would reduce applicability.

[0008] Preferably, the connecting assembly includes a plurality of through slots respectively formed on the side wall of the elastic connecting plate. The through slots are adapted to each other, and two threaded rods are slidably connected in every two through slots. One end of each threaded rod is threadedly connected to a nut, and the other end of the threaded rod is fixedly connected to a limit plate.

[0009] By adopting the above technical solution, after the elastic sealing gasket is squeezed against the pipe, the threaded rod is slid in the through groove so that the threaded rod is located on both sides of the pipe. Then, the nut is rotated to connect the elastic connecting plates, which can reduce the gap between the elastic sealing gasket and the pipe and reduce the speed of heat dissipation.

[0010] Preferably, the fixing component includes two connecting blocks respectively fixedly connected to one end of the arc-shaped clamp, one of the connecting blocks having a flexible U-shaped clamp hinged to one side, the U-shaped clamp being sleeved on the other connecting block.

[0011] By adopting the above technical solution, after the two arc-shaped clamps are brought close to each other, the U-shaped clamp is swung so that it fits onto the connecting block, connecting the two connecting blocks and making it easy to fix the two arc-shaped clamps.

[0012] Preferably, one side wall of the U-shaped card plate has a hole, and one side wall of one of the connecting blocks has a fixing rod that matches the hole.

[0013] By adopting the above technical solution, after the U-shaped clamp is placed on the connecting block, the fixing rod is inserted into the hole, which can improve the stability of the connection between the two arc-shaped clamps and prevent the U-shaped clamp from detaching from the connecting block.

[0014] Preferably, two anti-friction washers are fitted on the threaded rod, and the anti-friction washers are located between the nut and the limiting plate.

[0015] By adopting the above technical solution, the anti-friction washer can prevent the nut and the limiting plate from directly contacting the elastic connecting plate, thereby reducing friction on the elastic connecting plate.

[0016] Preferably, an L-shaped plate is fixedly connected to the side wall of the limiting plate away from the threaded rod, and the side wall of the L-shaped plate away from the limiting plate is in contact with the side wall of the elastic connecting plate.

[0017] By adopting the above technical solution, the L-shaped plate can prevent the limit plate from rotating, making it convenient to rotate the nut on the threaded rod and preventing the threaded rod from rotating along with the nut.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application utilizes the cooperative arrangement of structures such as elastic sealing gaskets, fixed plates, and elastic connecting plates. During use, two arc-shaped clamps are swung to fit onto the flange. Then, the two arc-shaped clamps are connected and fixed by a fixing assembly, allowing the heating plate to contact the flange and heat it. When the two arc-shaped clamps are fixed, the elastic sealing gasket contacts and compresses the pipe, causing the elastic connecting plate to bend and slide at both ends within the fixed plate. Subsequently, multiple elastic connecting plates are connected by a connecting assembly, allowing the elastic sealing gasket to wrap around the pipe and the flange. This minimizes the problem of excessive heat dissipation from the upper and lower surfaces of the flange during heating, which could lead to low temperatures at the pipe connection points, localized cold spots, and reduced applicability.

[0020] 2. After bringing the two arc-shaped clamps close to each other, swing the U-shaped clamp to fit the U-shaped clamp onto the connecting block, connect the two connecting blocks, and insert the fixing rod into the hole to facilitate the installation and fixing of the two arc-shaped clamps.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses a flange heating jacket.

[0028] Reference Figure 1 , Figure 2 and Figure 3A flange heating jacket includes two arc-shaped clamps 1, a heating plate 2 is fixedly connected to one side wall of the two arc-shaped clamps 1 opposite to each other, one end of the two arc-shaped clamps 1 is hinged together, and the two arc-shaped clamps 1 are provided with a fixing component for installation and a sealing component for preventing heat dissipation. The sealing component includes an elastic sealing gasket 3, a fixing plate 4 and an elastic connecting plate 5.

[0029] Multiple elastic sealing gaskets 3 are provided, and are respectively fixedly connected to the inner side wall of the arc-shaped clamp 1 and located on both sides of the heating plate 2. The elastic sealing gaskets 3 are made of Teflon material, which is resistant to high temperature and prevents damage caused by contact with the heating plate 2. Multiple fixing plates 4 are provided, and are respectively fixedly connected to the two side walls at both ends of the arc-shaped clamp 1. One side wall of the fixing plate 4 is fixedly connected to the elastic sealing gasket 3. Multiple elastic connecting plates 5 are provided, and are located on both sides of the elastic sealing gasket 3 and between two fixing plates 4. The two ends of the elastic connecting plate 5 pass through the fixing plate 4 and are slidably configured. One side wall of the elastic connecting plate 5 is fixedly connected to the elastic sealing gasket 3. The elastic connecting plate 5 is provided with connecting components.

[0030] Reference Figure 1 and Figure 3 The connecting assembly includes multiple through slots 6 respectively opened on the side wall of the elastic connecting plate 5. The through slots 6 are compatible with each other. Two threaded rods 7 are slidably connected in every two through slots 6. One end of the threaded rod 7 is threadedly connected to a nut 8, and the other end of the threaded rod 7 is fixedly connected to a limit plate 9. After the elastic sealing gasket 3 is squeezed against the pipe, the threaded rods 7 are slid in the through slots 6 so that the threaded rods 7 are located on both sides of the pipe. Then, the nut 8 is rotated to connect the elastic connecting plates 5. This can reduce the gap between the elastic sealing gasket 3 and the pipe and reduce the speed of heat dissipation.

[0031] Reference Figure 1 and Figure 4 The fixing component includes two connecting blocks 10 that are respectively fixedly connected to one end of the arc-shaped clamping plate 1. One of the connecting blocks 10 has a flexible U-shaped clamping plate 11 hinged to one side. The U-shaped clamping plate 11 is sleeved on the other connecting block 10. After the two arc-shaped clamping plates 1 are brought close to each other, the U-shaped clamping plate 11 is swung to make it sleeved on the connecting block 10, thereby connecting the two connecting blocks 10 and facilitating the fixing of the two arc-shaped clamping plates 1.

[0032] Reference Figure 4 The U-shaped clamp 11 has a hole 12 on one side wall, and a fixing rod 13 that matches the hole 12 is provided on one side wall of one of the connecting blocks 10. After the U-shaped clamp 11 is put on the connecting block 10, the fixing rod 13 is inserted into the hole 12, which can improve the stability of the connection between the two arc-shaped clamps 1 and prevent the U-shaped clamp 11 from detaching from the connecting block 10.

[0033] Reference Figure 1 and Figure 3 Two anti-friction washers 14 are fitted on the threaded rod 7. The anti-friction washers 14 are located between the nut 8 and the limiting plate 9. The anti-friction washers 14 can prevent the nut 8 and the limiting plate 9 from directly contacting the elastic connecting plate 5, thereby reducing the friction on the elastic connecting plate 5.

[0034] Reference Figure 3 An L-shaped plate 15 is fixedly connected to the side wall of the limiting plate 9 away from the threaded rod 7. The side wall of the L-shaped plate 15 away from the limiting plate 9 is in contact with the side wall of the elastic connecting plate 5. The L-shaped plate 15 can prevent the limiting plate 9 from rotating, making it convenient to rotate the nut 8 on the threaded rod 7, and preventing the threaded rod 7 from rotating when the nut 8 is rotated.

[0035] The implementation principle of a flange heating jacket according to an embodiment of this application is as follows: In use, by swinging two arc-shaped clamps 1, the arc-shaped clamps 1 are fitted onto the flange. After the two arc-shaped clamps 1 are brought closer together, the U-shaped clamp 11 is swinged to fit onto the connecting block 10, connecting the two connecting blocks 10. The fixing rod 13 is inserted into the hole 12, thus fixing the two arc-shaped clamps 1, so that the heating plate 2 contacts the flange and heats the flange. When the two arc-shaped clamps 1 are fixed, the elastic sealing gasket 3 contacts and squeezes the pipe. The elastic sealing gasket 3 causes the elastic connecting plate 5 to bend, and both ends slide in the fixed plate 4. Then, by sliding the threaded rod 7 in the through groove 6, the threaded rod 7 is positioned on both sides of the pipe. Then, the nut 8 is turned to connect the elastic connecting plates 5. This can reduce the gap between the elastic sealing gasket 3 and the pipe, reduce the speed of heat dissipation, and make the elastic sealing gasket 3 wrap around the pipe and the flange. This avoids the problem of low temperature at the pipe connection point and local cold spots that would reduce applicability if the upper and lower sides of the flange dissipate heat too quickly during the heating process.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
