Description

Technical Field

[0001] This utility model relates to the field of spiral flow channel tube technology, and more specifically to a spiral flow channel tube bundle support structure. Background Technology

[0002] Helical flow channel pipes are based on the principle of fluid dynamics. When fluid enters the helical flow channel, due to the helical shape of the channel, the fluid is forced to flow along the helical path. This flow mode can extend the flow path of the fluid and increase the contact area and time between the fluid and the pipe wall, thereby improving the heat transfer efficiency.

[0003] In practical applications, common spiral flow channel pipes are usually supported by U-shaped support plates. The spiral structure can increase turbulence inside the flow channel pipe and improve the heat transfer coefficient. However, as turbulence continues to be generated, random pressure pulsations will directly act on the pipe wall. When the pulsation frequency is close to the natural vibration frequency of the pipe, it will induce periodic vibration, which will lead to increased vibration of the pipe and support structure, resulting in increased wear of the pipe.

[0004] Therefore, a spiral flow channel tube bundle support structure is proposed to solve the problem of poor adsorption effect of the support structure on the pulsation of the tube fittings, which causes structural vibration. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a spiral flow channel tube bundle support structure to reduce tube wear and improve the energy release effect during tube pulsation.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a spiral flow channel tube bundle support structure, including a support plate and a main pipe. A spiral tube is fixedly connected between two support plates. A guide plate is evenly rotatably connected to the upper and lower sides of the spiral tube. A connecting plate is evenly fixedly connected to the upper and lower sides of the main pipe. A stabilizing rod is fixedly connected to the side of the connecting plate away from the pressure plate. A limit groove is opened on the connecting plate. A bidirectional screw is rotatably connected in the limit groove. Pressure plates are threaded to both sides of the bidirectional screw. A buffer pad is glued to one side of the pressure plate. A retainer is sleeved on the bidirectional screw. The retainer has an arc-shaped groove, which corresponds to the spiral tube.

[0007] As a preferred technical solution of this utility model, the upper end of the sleeve is fixedly connected to a pressure rod by bolts. The pressure rod corresponds to the spiral tube, and by setting the pressure rod, the contact surface with the spiral tube is increased.

[0008] As a preferred technical solution of this utility model, the pressure rod and the side opposite to the sleeve are both glued with a gasket. The gasket is made of rubber. By setting the gasket, the energy release effect can be improved.

[0009] As a preferred technical solution of this utility model, a spring is in contact with one side of the sleeve, the spring is sleeved on the bidirectional lead screw, and the bottom side of the spring is in contact with the pressure plate. By setting the spring, the rotation of the bidirectional lead screw can drive the spring to further compress and increase the preload.

[0010] As a preferred technical solution of this utility model, the pressure rod is threadedly connected to an adjusting rod, and the bottom end of the adjusting rod is rotatably connected to a pressure plate. By setting the adjusting rod, the contact surface between the pressure rod, the sleeve and the spiral tube is increased, thereby improving stability.

[0011] This utility model has the following advantages: by setting bidirectional screws, pressure plates, buffer pads, sleeves, arc grooves and pressure rods on both the upper and lower sides of the spiral tube, the upper and lower sides of the spiral tube can be limited, and the energy release effect of the spiral tube can be further improved by the stabilizing rod and adjusting rod, reducing the vibration of the tube caused by turbulence and reducing the adsorption of kinetic energy.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The spiral flow channel tube bundle support structure shown includes a support plate 1 and a main pipe 2. A spiral tube 3 is fixedly connected between the two support plates 1. Guide plates 4 are evenly rotatably connected to the upper and lower sides of the spiral tube 3. Connecting plates 5 are evenly fixedly connected to the upper and lower sides of the main pipe 2. A stabilizing rod 15 is fixedly connected to the side of the connecting plate 5 away from the pressure plate 8. By setting the stabilizing rod 15 on the two distant connecting plates 5, the stability of the connecting plate 5 when connecting the spiral tube 3 can be improved, and the wear of the equipment can be reduced. A limit groove 6 is opened on the connecting plate 5. A bidirectional screw 7 is rotatably connected in the limit groove 6. Rotating the bidirectional screw 7 can drive the two corresponding pressure plates 8 to move relative to each other, and then the spring 14 can be contracted to form a pre-tightening force, which facilitates the provision of a reverse force and facilitates the release of energy of the spiral tube 3. Pressure plates 8 are threadedly connected to both sides of the bidirectional screw 7. A buffer pad 9 is glued to one side of the pressure plate 8. A retainer 10 is sleeved on the bidirectional screw 7. The retainer 10 has an arc-shaped groove 11, which corresponds to the spiral tube 3.

[0018] The upper end of the sleeve 10 is fixedly connected to a pressure rod 12 by bolts. The pressure rod 12 corresponds to the spiral tube 3. By setting the pressure rod 12, the spiral tube 3 can be further limited.

[0019] Among them, the pressure rod 12 and the sleeve 10 are respectively glued to the side with a gasket 13. The gasket 13 is made of rubber. By setting the gasket 13, the friction between the pressure rod 12, the sleeve 10 and the spiral tube 3 is reduced.

[0020] One side of the ferrule 10 is in contact with a spring 14, which is sleeved on the bidirectional lead screw 7. The bottom side of the spring 14 is in contact with the pressure plate 8. By setting the spring 14, a pre-tightening force is formed between the ferrule 10 and the pressure plate 8, thereby reducing the vibration of the spiral tube 3.

[0021] The pressure rod 12 is threadedly connected to an adjusting rod 16, and the bottom end of the adjusting rod 16 is rotatably connected to a pressure plate. By rotating the adjusting rod 16, the contact surface with the spiral tube 3 can be increased, the stability of the spiral flow channel tube can be improved, and it is more suitable for spiral tubes 3 of different diameters.

[0022] Working principle: By setting multiple sets of corresponding connecting plates 5 in the main pipe 2, the sleeve 10 and the pressure rod 12 are connected to the spiral tube 3, and the adjusting rod 16 is rotated to make the pressure plate squeeze the spiral tube 3, which further provides the limit of the spiral tube 3. Then, the bidirectional screw 7 is rotated so that the pressure plate 8 cooperates with the sleeve 10 to squeeze the spring 14, which can form a pre-tightening force. When the spiral tube 3 vibrates, it cooperates with the buffer pad 9 to provide kinetic energy release and reduce the vibration of the spiral tube 3.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
