Technical Field

[0001] This utility model belongs to the technical field of heat exchanger equipment, and in particular relates to a flow distribution device for a heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, and are widely applied. A search revealed that patent application number 202221521264.8 discloses a flow distribution device for a heat exchanger, including a flow distribution pipe. The flow distribution pipe includes a pipe body, a main interface, and a flow distribution interface. The pipe body has a hollow structure. The main interface and the flow distribution interface are respectively located on the two side walls of the pipe body. A regulating valve is installed on each of the main interface and the flow distribution interface. One end of each of the main interface and the flow distribution interface is fixedly connected by welding. Flanges are installed on both ends of the pipe body and the other end of the main interface and the flow distribution interface. Plugs are installed on the flanges at both ends of the pipe body.

[0003] However, during actual use, the applicant found that the two ends of the tube body are sealed by plugs. When installing and removing the plugs, tools are needed to install and remove multiple bolts, which makes it inconvenient for personnel to inspect and maintain the inside of the tube body. In view of this, we propose a flow distribution device for heat exchangers. Utility Model Content

End panels are symmetrically fixed at both ends of the tube body, and end caps are rotatably connected to the end panels via hinge shafts. A sealing gasket is fixed on the inner wall of the end cap. Rotary supports are symmetrically fixedly installed at the top of the tube body on both sides of the main interface. A clamping bracket is rotatably connected to the rotating support via a connecting shaft. The end cap is clamped and fixed to the end panel via the clamping bracket. A nut support is fixedly installed at the top of the tube body between the main interface and the rotating support. A clamping screw is threaded through the nut support. A clamping head is provided at the end of the clamping screw near the clamping bracket, and a hand crank is provided at the end of the clamping screw away from the clamping bracket.

[0006] Preferably, the inner wall of the end cap is provided with a connecting groove, and the connecting grooves on the end cap are provided in a row at equal intervals from top to bottom.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a flow distribution device for a heat exchanger. By rotating the clamping screw in the forward direction, the clamping head moves towards the pressing bracket, pressing the tail end of the pressing bracket with the clamping head. This causes the pressing bracket to rotate downward around the connecting axis, and the pressing head presses against the outer wall of the end cover, pressing the end cover tightly onto the end panel. The end cover and the sealing gasket quickly seal the end of the tube. By rotating the clamping screw in the reverse direction, the pressing bracket can rotate upward around the connecting axis, allowing the end cover to flip downward around the hinge axis and open quickly, thus opening the end of the tube. This convenient operation facilitates internal inspection and maintenance of the tube. The cooperation between the connecting protrusion and the connecting groove allows for quick installation and removal of the sealing gasket, facilitating the replacement of aged sealing gaskets.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A flow distribution device for a heat exchanger includes a tube body 1. A main interface 11 is fixedly installed at the top of the tube body 1, and a first valve 2 is sleeved and fixedly installed on the main interface 11. Flow distribution interfaces 12 are fixedly installed side by side at equal intervals at the bottom of the tube body 1, and a second valve 3 is sleeved and fixedly installed on the flow distribution interfaces 12. End panels 13 are symmetrically fixedly installed at both ends of the tube body 1. End caps 4 are rotatably connected to the end panels 13 via hinge shafts. Sealing gaskets 7 are fixedly installed on the inner side walls of the end caps 4. Rotary supports 14 are symmetrically fixedly installed at the top of the tube body 1 on both sides of the main interface 11. A clamping bracket 5 is rotatably connected to the rotating support 14 via a connecting shaft. A pressing head 51 is fixedly installed at the front end of the clamping bracket 5. The end caps 4 are... The clamping bracket 5 is clamped and fixed to the end panel 13. The extrusion head 51 abuts against the outer wall of the end cover 4. The tail end of the clamping bracket 5 is rotatably connected to the rotating support 14. A nut support 15 is fixedly installed on the top of the tube body 1 between the main interface 11 and the rotating support 14. A clamping screw 6 is threaded through the nut support 15. A clamping head 61 is provided at the end of the clamping screw 6 near the clamping bracket 5. The clamping head 61 abuts against the end face of the tail end of the clamping bracket 5. A hand crank 62 is provided at the end of the clamping screw 6 away from the clamping bracket 5. By rotating the clamping screw 6 in the forward direction, the clamping head 61 is moved towards the clamping bracket 5, and the clamping head 61 can clamp the tail end of the clamping bracket 5. The clamping bracket 5 rotates downward around the connecting axis, and the clamping head 51 presses against the outer wall of the end cap 4, pressing the end cap 4 tightly against the end panel 13. The end cap 4 and the sealing gasket 7 quickly seal the port of the pipe body 1. By rotating the clamping screw 6 in the reverse direction, the clamping bracket 5 can rotate upward around the connecting axis, allowing the end cap 4 to flip downward around the hinge axis and open, thus quickly opening the port of the pipe body 1. This convenient operation facilitates the internal inspection and maintenance of the pipe body 1. When internal maintenance of the pipe body 1 is required, the clamping screw 6 can be rotated in the reverse direction by rotating the hand crank 62. The rotation of the clamping screw 6 can drive the clamping head 61 away from the end cap 13. The clamping bracket 5 is moved in the direction of the connection axis. At this time, the clamping bracket 5 can be rotated upward around the connection axis, and the end cover 4 can be flipped downward around the hinge axis to open it. The internal inspection and maintenance of the pipe body 1 can then be performed. After maintenance, the end cover 4 is flipped upward around the hinge axis to close it, and the clamping bracket 5 is rotated downward around the connection axis so that the pressing head 51 abuts against the end cover 4. Then, the hand crank 62 is rotated in the forward direction to drive the clamping screw 6 to rotate, which can drive the clamping head 61 to move towards the clamping bracket 5 and make the clamping head 61 abut against the tail end of the clamping bracket 5. This can drive the clamping bracket 5 to rotate downward. By pressing the end cover 4 with the pressing head 51, the port of the pipe body 1 can be quickly sealed.

[0022] A connecting groove 41 is provided on the inner wall of the end cap 4, and several connecting grooves 41 are provided side by side at equal intervals from top to bottom on the end cap 4. A connecting protrusion 71 is fixedly provided on one side of the sealing gasket 7, and several connecting protrusions 71 are provided side by side at equal intervals from top to bottom on the sealing gasket 7. The connecting protrusion 71 is engaged in the connecting groove 41. Through the cooperation between the connecting protrusion 71 and the connecting groove 41, it is easy for personnel to quickly install and remove the sealing gasket 7, thereby facilitating the replacement of the aged sealing gasket 7. When the sealing gasket 7 is aged and needs to be replaced, the connecting protrusion 71 on the sealing gasket 7 can be pulled out from the connecting groove 41, and the aged sealing gasket 7 can be removed from the end cap 4. Then, the connecting protrusions 71 on the new sealing gasket 7 are aligned one by one and engaged in the corresponding connecting grooves 41 on the end cap 4, thereby fixing the new sealing gasket 7 on the end cap 4 and completing the quick replacement of the sealing gasket 7.

[0023] Working principle: When internal maintenance of the tube body 1 is required, the hand crank 62 can be rotated in the reverse direction to drive the clamping screw 6 to rotate. The rotation of the clamping screw 6 can drive the clamping head 61 to move away from the clamping bracket 5. At this time, the clamping bracket 5 can be rotated upward around the connecting axis, and the end cover 4 can be flipped downward around the hinge axis to open, so that the internal maintenance of the tube body 1 can be performed. After maintenance, the end cover 4 can be flipped upward around the hinge axis to close, and the clamping bracket 5 can be rotated downward around the connecting axis to make the clamping head 51 abut against the end cover 4. Then, the hand crank 62 can be rotated in the forward direction to drive the clamping screw 6 to rotate, which can... The clamping head 61 is moved toward the clamping bracket 5 and pressed against the tail end of the clamping bracket 5, thereby causing the clamping bracket 5 to rotate downward. The end cap 4 is pressed against the clamping head 51, thus quickly sealing the port of the tube body 1. When the sealing gasket 7 ages and needs to be replaced, the connecting protrusion 71 on the sealing gasket 7 can be pulled out from the connecting groove 41, and the aged sealing gasket 7 can be removed from the end cap 4. Then, the connecting protrusions 71 on the new sealing gasket 7 are aligned one by one and inserted into the corresponding connecting grooves 41 on the end cap 4, thus fixing the new sealing gasket 7 on the end cap 4 and completing the quick replacement of the sealing gasket 7.
