Description

Technical Field

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

[0002] The shell and tube heat exchanger in the prior art is usually provided with an arched baffle, which is a component that supports the heat exchange tubes. It is usually made of steel plates and is in an arched shape. The arch is formed by cutting off 1 / 4 to 1 / 3 of a circle. The fluid passes through the notch. Tube holes are provided on the arched baffle for the heat exchange tubes to pass through, thereby supporting the heat exchange tubes. Several baffles are arranged at equal intervals along the axial direction.

[0003] Generally, when a heat exchanger is hit, the internal components will be dislocated by the impact force, so that the heat exchanger cannot be used normally after the collision, and the service life of the heat exchanger is also affected. For this reason, we provide a tube bundle support structure for a shell and tube heat exchanger. Utility Model Content

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.

[0020] like Figure 1-3As shown, the utility model provides a technical solution: a tube bundle supporting structure of a shell and tube heat exchanger, comprising a U-shaped plate 1, the inner wall of the U-shaped plate 1 is hinged with two limit cylinders 4, the outer surfaces of the two limit cylinders 4 are slidably connected to limit rods 5, the ends of the two limit rods 5 close to each other are commonly fixedly connected to a first C-shaped plate 6, the bottom surface of the first C-shaped plate 6 is fixedly connected to a damper 7, and the bottom end of the damper 7 is fixedly connected to the inner bottom wall of the U-shaped plate 1, the inner bottom wall of the U-shaped plate 1 is fixedly connected to a telescopic cylinder 8, the upper surface of the telescopic cylinder 8 is slidably connected to a telescopic rod 9, and a spring 10 is fixedly connected between the telescopic cylinder 8 and the telescopic rod 9.

[0021] When the components fixed inside the second C-shaped plate 11 shake, the limit cylinder 4 and the limit rod 5 can limit the left and right movement of the second C-shaped plate 11. At this time, the telescopic rod 9 begins to shrink, and the damper 7 will shrink during the shrinkage process. The damping generated by the damper 7 during the shrinkage process can achieve shock absorption of the components, thereby ensuring the normal use of the components.

[0022] The left and right sides of the U-shaped plate 1 are fixedly connected with fixing blocks 2, and the upper surfaces of the two fixing blocks 2 are threadedly connected with fastening bolts 3, so that the installation of the device is realized and the subsequent use is convenient.

[0023] The upper surface of the first C-shaped plate 6 is hinged to the second C-shaped plate 11 by a hinge, and the outer surfaces of the second C-shaped plate 11 and the first C-shaped plate 6 are fixedly connected with a fixing plate 12. The two fixing plates 12 are threadedly connected by fixing bolts 13, thereby achieving the closure of the wall between the second C-shaped plate 11 and the first C-shaped plate 6 and fixing the component.

[0024] The outer surface of the second C-shaped plate 11 is threadedly connected with a threaded rod 14, and the bottom end of the threaded rod 14 is fixedly connected with a limiting plate 15, so as to achieve fixed limitation of the component and ensure the normal use of the component.

[0025] Two connecting rods 16 are fixedly connected to the outer surface of the limiting plate 15, and the outer surface of the connecting rod 16 is slidably connected to the outer surface of the second C-shaped plate 11, thereby guiding the limiting plate 15 and ensuring the stability of the limiting plate 15 when moving.

[0026] During use, when the components fixed inside the second C-shaped plate 11 shake, the limit cylinder 4 and the limit rod 5 can limit the left and right movement of the second C-shaped plate 11. At this time, the telescopic rod 9 begins to shrink, and the damper 7 will shrink during the shrinkage process. The damping generated during the shrinkage of the damper 7 can achieve shock absorption of the components and ensure the normal use of the components. At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
