Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transmission, in particular to a gas medium temperature and pressure uniformity device in passive pipeline transmission. Background Art

[0002] Currently, hot and cold air (i.e., gaseous media) transported through pipelines experience significant temperature and pressure differences across the cross-section of the pipeline after heat exchange due to various factors, including pipeline structure, pipe diameter, and heat exchanger configuration. This can lead to various problems later on due to these temperature and pressure differences within the media. The most fundamental solution to these problems is to retrofit and upgrade the traditional heat exchanger and transmission pipeline structures, but this is costly and difficult to implement. On some existing machines, this modification and upgrade is not possible due to limitations in the original structure.

[0003] Therefore, we propose a device for uniform temperature and pressure of gas medium in passive pipeline transmission in order to solve the problems raised above. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a device for uniform temperature and pressure of gas medium in passive pipeline transmission, comprising a circular ring and an axis arranged in the middle of the inner cavity of the circular ring, a support bar being movably installed at the rear end of the axis, and a plurality of fan blades being fixedly installed at equal intervals on the outer side of the axis, an adjustment connecting block being commonly provided between adjacent fan blades, and a plurality of fixing holes being opened on the circular ring.

[0006] Preferably, the fan blades and the shaft are integrally die-cast.

[0007] Preferably, any two of the fan blades are connected by snapping together with the adjustment connection block through a bayonet, and the setting of the adjustment connection block is used to fine-tune the degree of distortion of the fan blades and enhance the strength of the fan blades.

[0008] Preferably, the number of the fixing holes is four, and the fixing holes are distributed on four sides of the ring for installing and fixing the ring.

[0009] Preferably, both ends of the support bar are fixedly mounted on the inner wall of the rear side of the inner cavity of the ring, for connection between the ring and the axis.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Through the mutual cooperation between the ring, fan blades, fixing holes, adjustment connection blocks, axis and support bars, the fan blades can be strengthened, and the fan blades can also be de-shaken and the fan blade operation noise can be reduced. In addition, the manufacturing and assembly costs of the device can be low, no external energy is required, and the problem of temperature and pressure gradient differences in the transmission of gas media in pipelines and heat exchange structures can be solved. At the same time, the installation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 A device for uniform temperature and pressure of gas medium in passive pipeline transmission includes a circular ring 1 and an axis 5 arranged in the middle of the inner cavity of the circular ring 1. A support bar 6 is movably installed at the rear end of the axis 5, and a plurality of fan blades 2 are fixedly installed at equal intervals on the outer side of the axis 5. The fan blades 2 are arranged in a twisted shape, and an adjustment connection block 4 is commonly provided between adjacent fan blades 2. A plurality of fixing holes 3 are opened on the circular ring 1.

[0019] The fan blades 2 and the shaft 5 are integrally die-cast.

[0020] Any two blades 2 are connected by snapping together with the adjustment connection block 4 through a bayonet, and the setting of the adjustment connection block 4 is used to fine-tune the degree of distortion of the blades 2 and enhance the strength of the blades 2, which can reduce the shear caused by gas impact.

[0021] The number of the fixing holes 3 is four, and the fixing holes 3 are distributed on four sides of the ring 1 for installing and fixing the ring 1. The dispersed arrangement has a better installation effect.

[0022] The two ends of the support bar 6 are respectively fixedly mounted on the inner wall of the rear side of the inner cavity of the ring 1, and are used to connect the ring 1 and the axis 5, playing a connecting role.

[0023] Specifically, a number of twisted fan blades 2 are radially extended from the axis 5 and are arranged at equal intervals. There is an adjustment connecting block 4 between every two fan blades 2. The adjustment block serves to strengthen the fan blades 2, and also serves to eliminate the shaking of the fan blades 2 and reduce the operating noise of the fan blades 2. The fan blades 2 can move in a circle around the axis 5. This device is a passive device. When the gas in the pipeline passes through the fan blades 2, due to the pressure difference on the two side surfaces of the fan blades 2, the fan blades 2 rotate around the axis 5. At the same time, the fan blades 2 shear the gas when rotating. Under the stirring of the fan blades 2, the temperature and pressure difference in the pipeline cross section are reduced, and the use effect is good.

[0024] Working principle: The setting of the fixing hole 3 is convenient for the installation and disassembly of the device, and several twisted fan blades 2 can make circular motion around the axis 5, and adjusting the setting of the connecting block 4 can strengthen the fan blade 2, and also reduce the shaking of the fan blade 2 during operation and reduce the operating noise of the fan blade 2. When the gas in the pipeline passes through the fan blades 2, the fan blade 2 rotates around the axis 5, and the fan blade 2 shears the gas when rotating. Under the stirring of the fan blade 2, the temperature and pressure difference in the cross section of the pipeline is reduced. The ring 1 is fixed to the axis 5 by the support bar 6, and the setting of the connecting block 4 can also fine-tune the degree of distortion of the fan blade 2, and at the same time increase the strength of the fan blade 2 and reduce the deformation and shear caused by gas impact.
