Description

Technical Field

[0001] The utility model relates to the technical field of shell and tube heat exchangers, in particular to a shell and tube heat exchanger support. Background Art

[0002] Shell and tube heat exchanger is also called shell and tube heat exchanger. Shell and tube heat exchanger is a common heat exchange equipment, which consists of a group of tube bundles and a shell. The hot fluid flows in the tube or shell, and exchanges heat with another fluid through the tube wall. Due to the temperature difference between the shell side medium and the tube side medium, the temperature difference causes the shell and tube bundle of the heat exchanger to produce thermal expansion and displacement in the axial direction. It is necessary to ensure that the heat exchanger can work normally during operation and avoid equipment damage caused by thermal stress. The existing heat exchanger sliding support has a relatively simple structure and cannot work normally under special conditions. There is also a problem of displacement caused by thermal expansion. Secondly, there is a problem that the vibration is difficult to absorb during the operation of the heat exchanger and the friction between the sliding parts causes serious wear, which affects the normal operation and life of the heat exchanger.

[0003] Therefore, a shell and tube heat exchanger support is needed that can solve the problems of normal operation, thermal expansion displacement, and severe friction and wear between sliding parts under certain special conditions. Utility Model Content

A spring damper is arranged on the outer side of the movable rod, one side of the spring damper is fixed to the inner cavity of the base, and the other side of the spring damper is fixed to the bottom of the connecting platform. A bearing seat is arranged on the left side of the top of the connecting platform, and an axis fixing clamp is arranged on the right side of the top of the connecting platform. A bearing is arranged in the bearing seat, the outer ring of the bearing is fixed to the bearing seat, the inner ring of the bearing is fixed to the outer circle of the rotating rod, one end of the rotating rod is fixed to the inner ring of the bearing in the bearing seat, and the other end of the rotating rod is fixed to the axis fixing clamp. The surface of the rotating rod is connected with an arc seat, and a plurality of threaded holes are opened on the arc surface of the top of the arc seat, and a ball screw is threadedly connected inside the threaded hole.

[0008] (2) By providing a spring damper, when the heat exchanger vibrates during operation, the spring damper 3 will stretch due to the vibration of the shell and tube heat exchanger to meet the working requirements of the shell and tube heat exchanger and prevent the shell and tube heat exchanger from affecting the normal operation of the heat exchanger due to vibration;

[0009] (3) By providing the ball screw and the spring damper, when the shell of the heat exchanger generates thermal expansion and displacement, the spring damper can absorb a part of the radial deformation force, the ball screw can evenly distribute the force on the contact surface, and enable the heat exchanger to slide smoothly, thereby preventing the support and the machine from being deformed or damaged.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-2The utility model provides a technical solution: a shell and tube heat exchanger support, including a base 1, four threaded holes are respectively arranged around the base 1, the threaded holes are connected to the fixing screws 2, the inner cavity of the base 1 is provided with 6 groups of slide grooves 11, the inner sliding connection of the slide grooves 11 is provided with a movable rod 10, the outer side of the movable rod 10 is provided with a spring damper 3, one side of the spring damper 3 is fixed to the inner cavity of the base 1, and the other side of the spring damper 3 is fixed to the bottom of the connecting platform 4, a bearing seat 6 is arranged on the left side of the top of the connecting platform 4, and an axis fixing clamp 5 is arranged on the right side of the top of the connecting platform 4, a rotating rod 7 is connected to the bearing in the bearing seat 6, one end of the rotating rod 7 is fixed to the axis fixing clamp 5, the surface of the rotating rod 7 is connected with an arc seat 8, a plurality of threaded holes are arranged on the arc surface of the top of the arc seat 8, and a ball screw 9 is threadedly connected to the inner part of the threaded hole.

[0016] Working principle: When the utility model is used, first during installation, the arc seat 8 is rotated to the working angle, the screws on the locking shaft fixing clamp 5 are locked, and the angle of the rotating rod 7 is locked, so that the shell and tube heat exchanger reaches the most suitable working angle and adapts to different working environments. Then the shell and tube heat exchanger is placed on the arc seat 8, forming point contact with the ball screw 9, reducing the friction between the sliding parts and improving the life of the bracket. When the shell and tube heat exchanger vibrates during operation, the spring damper 3 will stretch due to the vibration of the shell and tube heat exchanger to meet the working requirements of the shell and tube heat exchanger, and can avoid the shell and tube heat exchanger from affecting the normal operation of the heat exchanger due to vibration, shortening the service life of the bracket. During the operation of the shell and tube heat exchanger, when the shell of the heat exchanger generates thermal expansion and displacement, the spring damper 3 can absorb part of the radial deformation force, the ball screw 9 can evenly distribute the force on the contact surface, and enable the heat exchanger to slide smoothly, preventing the support and the machine from deformation or damage. It enables the heat exchanger to slide smoothly and bear force evenly, reduces stress concentration and wear, and ensures stable operation and extended service life of the equipment under various working conditions.
