[0002] The reinforced tube sheet is a structure that fixes the tube bundle and is usually used in shell and tube heat exchangers. Its main function is to increase the strength and stability of the tube bundle, thereby ensuring the normal operation of the shell and tube heat exchanger. In a shell and tube heat exchanger, the tube bundle is composed of multiple tubes, which need to be relatively fixed at a certain position and angle. If the tube bundle is not well fixed, there will be problems such as tube vibration, collision, and swing, which will affect the heat exchange efficiency and cause equipment damage. Most of the existing reinforced tube sheets are fixed to the tubular shell by welding, which is inconvenient to replace and disassemble later.

[0023] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The fixing mechanism includes a cross-shaped slide groove 2 which runs through the fixing plate 1. A tooth groove 21 is also provided in the fixing plate 1 at the center of the cross-shaped slide groove 2. A driving gear 22 is rotatably connected in the tooth groove 21. A plurality of driven gears 23 are meshed and connected on one side of the driving gear 22. A threaded rod 24 is fixedly connected to the side of each driven gear 23 away from the center of the fixing plate 1, and each threaded rod 24 is respectively located in the slide groove 2. A threaded inner cylinder 25 is threadedly connected to the outer side of each threaded inner cylinder 25. A guide plate 26 is fixedly connected to the outer side of each threaded inner cylinder 25. The slide groove 2 is provided with a guide groove 27 corresponding to the guide plate 26. The fixing member includes a plurality of abutment plates 28. A side of each abutment plate 28 close to the fixing plate 1 is fixedly connected to the threaded inner cylinder 25. A protective cover 29 is fixedly connected to one side of the fixing plate 1. A driving member for driving the driving gear 22 to rotate is fixedly installed in the protective cover 29.

[0024] It should be noted that: a slide groove 2 and a tooth groove 21 are provided in the fixing plate 1, and the design and combination of the fixing mechanism are completed through these structures and components such as the driving gear 22 and the driven gear 23, so as to realize the fixing and disassembly operations of the fixing plate 1 and the tubular shell. The driven gears 23 are not engaged. The combination of the threaded rod 24 and the threaded inner cylinder 25 enables the installation and disassembly of the fixing mechanism to be completed by rotating the threaded rod 24 without the need for a complicated disassembly process. The guide plate 26 and the guide groove 27 can provide the positioning and guiding functions of the fixing mechanism, thereby enhancing the stability and safety of the fixing mechanism. The design of the abutment plate 28 and the protective cover 29 enhances the integrity and sealing of the fixing mechanism structure, and plays a role in protection and maintenance. The driving member is a servo motor.

[0025] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The elastic mechanism includes a slide plate 3 provided on the side of the fixed plate 1 away from the protective cover 29, and a plurality of springs 31 are fixedly connected to the side of the slide plate 3 close to the fixed plate 1. The side of each spring 31 away from the slide plate 3 is fixedly connected to the fixed plate 1, and the side of the fixed plate 1 away from the protective cover 29 is fixedly connected to a slide rod 32. The side of the slide rod 32 away from the fixed plate 1 passes through the protective cover 29 and is fixedly connected to a limiting plate 33. Plate holes 11 are penetrated on the fixed plate 1 and the protective cover 29, and each plate hole 11 is chamfered.

[0026] It should be noted that the skateboard 3 is located on the side of the fixed plate 1 away from the protective cover 29, and is connected to the fixed plate 1 through multiple springs 31. It is elastic. The springs 31 connect the skateboard 3 and the fixed plate 1, and can provide elastic support to ensure the elastic movement of the skateboard 3.

[0027] The working principle of the reinforced tube sheet for heat exchanger provided by the utility model is as follows: put the fixed plate 1 into the tubular shell, start the driving member, rotate the driving gear 22 fixedly connected to the output end of the driving member, so that the driven gear 23 meshing with the driving gear 22 rotates, and then the threaded rod 24 meshing with the driven gear 23 rotates, so that the threaded inner cylinder 25 threadedly connected to the outer side of the threaded rod 24 rotates, so that the threaded inner cylinder 25 moves along the slide groove 2 to the outside of the fixed plate 1, and then the abutment plate 28 connected to the threaded inner cylinder 25 fits with the inner wall of the tubular shell for fixing. The fixed plate 1 and the slide plate 3 are connected by a spring 31. When the medium contacts the slide plate 3, the slide plate 3 will be impacted by the medium and slide along the slide rod 32, so that the spring 31 is compressed. Due to the characteristics of the spring 31 itself, it will rebound after compression, and then the slide plate 3 will slide back and forth along the slide rod 32, so as to avoid the slide plate 3 and the heating tube from being fixed for a long time and rusting.

[0028] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
