[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 This utility model provides a technical solution:

[0029] A detachable mounting bracket for a shell-and-tube heat exchanger includes a base 1 and a shell-and-tube heat exchanger body 2. Symmetrical support plates 3 are fixedly mounted on the bottom surface of the shell-and-tube heat exchanger body 2, and insertion plates 4 are fixedly mounted on the bottom surface of each support plate 3. Symmetrical insertion slots 5 are provided on the base 1, and the dimensions of the insertion plates 4 are adapted to the dimensions of the insertion slots 5. Fixing members 6 for fixing the insertion plates 4 are provided on the base 1 and the insertion plates 4. A symmetrical frame 7 is fixedly mounted on the base 1, and a lead screw 8 is rotatably mounted inside the frame 7. A support plate 9 is slidably mounted on the frame 7 and threadedly connected to the lead screw 8. A horizontal plate 10 is fixedly mounted on the side of each support plate 3, directly opposite the support plate 9. A lifting member 11 for driving the support plate 9 to move vertically is provided on the base 1. The fixing member 6 includes a mounting opening 61 on the base 1 located on the side of the insertion slots 5, and a mounting bracket 6 for... The spring 62 inside the mounting port 61, the fixing block 63 slidably disposed on the mounting port 61, and the fixing port 64 opened on the side of the insert plate 4. The two ends of the spring 62 are fixedly installed to the base 1 and the fixing block 63 respectively, and the spring 62 is pressed between the base 1 and the fixing block 63. The fixing block 63 and the fixing port 64 are disposed on matching arc surfaces. The lifting component 11 includes a motor 111 fixedly installed on the side of the base 1, a crossbar 112 rotatably disposed in the base 1, a first bevel gear 113 fixedly installed on the crossbar 112, and a second bevel gear 114 rotatably disposed in the base 1. The output shaft end of the motor 111 is fixedly installed to the rotating shaft end of the crossbar 112. The first bevel gear 113 is meshed and connected to the second bevel gear 114 respectively. The rotating shaft end of the second bevel gear 114 is fixedly installed to the rotating shaft end of the lead screw 8 respectively.

[0030] When installing the shell-and-tube heat exchanger body 2, the insert plate 4 at the bottom of the symmetrical support plate 3, which is fixedly installed on the bottom surface of the shell-and-tube heat exchanger body 2, is aligned with the symmetrical insertion port 5 opened on the base 1 and inserted. During the insertion of the insert plate 4 into the insertion port 5, the side of the insert plate 4 will press against the fixing block 63 located in the mounting opening 61 on the side of the insertion port 5 on the base 1. Since the fixing block 63 is slidably mounted on the mounting opening 61, and both ends of the spring 62 are fixedly installed to the base 1 and the fixing block 63 respectively, and the spring 62 is pressed between the base 1 and the fixing block 63, the fixing block 63... The fixed block 63 is compressed and retracts into the mounting port 61. The spring 62 is compressed. When the insert plate 4 is fully inserted into the insertion port 5 and the fixing port 64 on the side of the insert plate 4 moves to the position corresponding to the fixed block 63, the fixed block 63 pops out from the mounting port 61 and is inserted into the fixing port 64 under the elastic restoring force of the spring 62, thereby fixing the insert plate 4 and completing the installation and fixing of the shell and tube heat exchanger body 2 on the base 1. After the shell and tube heat exchanger body 2 is installed and fixed, the horizontal plate 10 on the side of the support plate 3 just fits against the support plate 9.

[0031] When it is necessary to disassemble the shell-and-tube heat exchanger body 2, the motor 111 on the side of the base 1 is started. The output shaft of the motor 111 begins to rotate. Since the end of the output shaft of the motor 111 is fixedly installed with the shaft end of the crossbar 112, the crossbar 112 will rotate synchronously within the base 1 as the output shaft of the motor 111 rotates. A symmetrical bevel gear 113 is fixedly installed on the crossbar 112. The rotation of the crossbar 112 drives the bevel gear 113 to rotate. Since the bevel gear 113 is meshed and connected with the bevel gear 114, the rotation of the bevel gear 113 will drive the bevel gear 114 to rotate within the base 1. The shaft end of the bevel gear 114 is fixedly installed with the shaft end of the lead screw 8. Therefore, the bevel gear The rotation of 114 will drive the lead screw 8 to rotate inside the frame 7. A support plate 9 is slidably installed inside the frame 7 and is threadedly connected to the lead screw 8. When the lead screw 8 rotates, the support plate 9 will slide vertically upward on the frame 7. Since the horizontal plate 10 is directly opposite the support plate 9 and is fixedly installed on the side of the support plate 3, the upward movement of the support plate 9 will drive the horizontal plate 10 to move upward synchronously. This will cause the support plate 3 connected to the horizontal plate 10 and the shell-and-tube heat exchanger body 2 to move upward as a whole. During the upward movement of the shell-and-tube heat exchanger body 2, the support plate 3 and the insert plate 4, the fixing block 63 overcomes the elastic force of the spring 62 in the mounting port 61 and moves the fixing block 63 out of the fixing port 64, releasing the fixing effect of the fixing block 63 on the insert plate 4. After that, the insert plate 4 moves out of the insertion port 5, thus completing the disassembly of the shell-and-tube heat exchanger body 2.

[0032] The shell-and-tube heat exchanger uses a detachable mounting bracket, which enables easy installation and disassembly of the shell-and-tube heat exchanger body 2, significantly improving the installation and maintenance efficiency of the equipment and making it highly practical.

[0033] The surfaces of the tray 9 and the cross plate 10 are covered with pads, which are made of rubber.

[0034] The rubber pads laid on the surfaces of the support plate 9 and the horizontal plate 10 can improve the stability of the support plate 9 driving the horizontal plate 10 to rise vertically, thereby improving the stability of disassembly and ensuring high safety.

[0035] Working principle:

[0036] When installing the shell-and-tube heat exchanger body 2, the insert plate 4 at the bottom of the symmetrical support plate 3, which is fixedly installed on the bottom surface of the shell-and-tube heat exchanger body 2, is aligned with the symmetrical insertion port 5 opened on the base 1 and inserted. During the insertion of the insert plate 4 into the insertion port 5, the side of the insert plate 4 will press against the fixing block 63 located in the mounting opening 61 on the side of the insertion port 5 on the base 1. Since the fixing block 63 is slidably mounted on the mounting opening 61, and both ends of the spring 62 are fixedly installed to the base 1 and the fixing block 63 respectively, and the spring 62 is pressed between the base 1 and the fixing block 63, the fixing block 63... The fixed block 63 is compressed and retracts into the mounting port 61. The spring 62 is compressed. When the insert plate 4 is fully inserted into the insertion port 5 and the fixing port 64 on the side of the insert plate 4 moves to the position corresponding to the fixed block 63, the fixed block 63 pops out from the mounting port 61 and is inserted into the fixing port 64 under the elastic restoring force of the spring 62, thereby fixing the insert plate 4 and completing the installation and fixing of the shell and tube heat exchanger body 2 on the base 1. After the shell and tube heat exchanger body 2 is installed and fixed, the horizontal plate 10 on the side of the support plate 3 just fits against the support plate 9.

[0037] When it is necessary to disassemble the shell-and-tube heat exchanger body 2, the motor 111 on the side of the base 1 is started. The output shaft of the motor 111 begins to rotate. Since the end of the output shaft of the motor 111 is fixedly installed with the shaft end of the crossbar 112, the crossbar 112 will rotate synchronously within the base 1 as the output shaft of the motor 111 rotates. A symmetrical bevel gear 113 is fixedly installed on the crossbar 112. The rotation of the crossbar 112 drives the bevel gear 113 to rotate. Since the bevel gear 113 is meshed and connected with the bevel gear 114, the rotation of the bevel gear 113 will drive the bevel gear 114 to rotate within the base 1. The shaft end of the bevel gear 114 is fixedly installed with the shaft end of the lead screw 8. Therefore, the bevel gear The rotation of 114 will drive the lead screw 8 to rotate inside the frame 7. A support plate 9 is slidably installed inside the frame 7 and is threadedly connected to the lead screw 8. When the lead screw 8 rotates, the support plate 9 will slide vertically upward on the frame 7. Since the horizontal plate 10 is directly opposite the support plate 9 and is fixedly installed on the side of the support plate 3, the upward movement of the support plate 9 will drive the horizontal plate 10 to move upward synchronously. This will cause the support plate 3 connected to the horizontal plate 10 and the shell-and-tube heat exchanger body 2 to move upward as a whole. During the upward movement of the shell-and-tube heat exchanger body 2, the support plate 3 and the insert plate 4, the fixing block 63 overcomes the elastic force of the spring 62 in the mounting port 61 and moves the fixing block 63 out of the fixing port 64, releasing the fixing effect of the fixing block 63 on the insert plate 4. After that, the insert plate 4 moves out of the insertion port 5, thus completing the disassembly of the shell-and-tube heat exchanger body 2.

[0038] The shell-and-tube heat exchanger uses a detachable mounting bracket, which enables easy installation and disassembly of the shell-and-tube heat exchanger body 2, significantly improving the installation and maintenance efficiency of the equipment and making it highly practical.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
