Description

Technical Field

[0001] This utility model relates to the field of heat exchanger pipe connection technology, and in particular to an alloy reducer for a multi-row perforated heat exchanger. Background Technology

[0002] Alloy reducers for multi-row perforated heat exchangers are irregularly shaped connectors adapted to multi-row perforated heat exchange systems. Made of temperature-resistant and corrosion-resistant alloy materials, they feature a variable diameter transition function. Their structural characteristic is that the two ends have different diameters; one end matches the multi-row perforation interface of the heat exchanger tube bundle, and the other end connects to the piping system. The inner wall has a flow-guiding structure adapted to the multi-row perforation layout, reducing fluid resistance. This component must meet the concentricity accuracy requirements of the multi-row perforations to ensure precise alignment with the heat exchanger perforation rows. Through the strength, toughness, and fatigue resistance of the alloy material, it adapts to frequent temperature changes in the heat exchange system, improving media flow efficiency and overall equipment sealing. It is widely used for piping transition connections in multi-row perforated heat exchange equipment in chemical, energy, and other industries.

[0003] While existing multi-row perforated heat exchanger connecting pipe fittings can achieve basic pipe diameter transition and fluid distribution functions, they have some shortcomings in practical applications. During use, the structural strength of the pipe connections is insufficient. After long-term exposure to fluid pressure and temperature changes, the connections are prone to loosening and deformation, affecting sealing performance. Furthermore, due to the lack of guiding structures, eddies are easily generated at pipe diameter changes when the fluid flows inside the fittings, resulting in significant pressure loss and reducing the overall heat exchanger efficiency.

[0004] Therefore, this utility model provides a rubber roller for processing wood grain decorative paper to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an alloy reducer for a multi-row perforated heat exchanger, which solves the problems of insufficient structural strength of the pipe connection part during use, which easily leads to loosening and deformation of the connection after long-term exposure to fluid pressure and temperature changes, affecting the sealing performance. At the same time, when the fluid flows inside the pipe, due to the lack of a guiding structure, eddies are easily generated at the pipe diameter change point, resulting in a large pressure loss and reducing the overall heat exchange efficiency of the heat exchanger.

[0006] To achieve the above objectives, this utility model provides an alloy reducer for a multi-row perforated heat exchanger, comprising a connecting assembly, the connecting assembly including an alloy reducer housing, and a reinforcing assembly on the outer side of the alloy reducer. The reinforcing assembly includes six external bonding strips, which are positioned correspondingly. Each external bonding strip has a threaded groove on its outer surface, and a reinforcing bolt is screwed into the threaded groove. The rear ends of the six external bonding strips are fixedly connected to the outer surface of the alloy reducer housing. Among them, a square limiting block is fixedly connected to the upper rear surface of each of the six alloy large and small head shells, and the front surface of the square limiting block is movably connected to the rear surface of the reinforcing bolt.

[0007] Each of the six alloy large and small head shells has a rubber friction pad fixedly connected to its lower front surface, and the lower surface of each rubber friction pad has friction patterns.

[0008] The inner wall of the alloy reducer housing is fixedly connected to a circular mounting plate, and the side surface of the circular mounting plate is provided with five circular mounting holes that are evenly distributed on the side surface of the circular mounting plate.

[0009] Each of the five circular mounting plates is fixedly connected to a circular connecting pipe, and the two outer circular connecting pipes are fixedly connected to triangular support blocks on their side surfaces.

[0010] The outer surface of the triangular support block is fixedly connected to the inner wall of the alloy reducer housing, and the front surface of the triangular support block is fixedly connected to the rear surface of the circular mounting plate.

[0011] The circular mounting plate has two inclined platforms fixedly connected to its front surface. The outer surfaces of the two inclined platforms are fixedly connected to the inner wall of the alloy reducer housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting a reinforcing component with six corresponding external bonding strips on the outer side of the alloy reducer shell, cooperating with the reinforcing bolts screwed into the threaded grooves of the external bonding strips, and a square limiting block fixed on the upper rear surface of the alloy reducer shell, the front surface of which is movably connected to the rear surface of the reinforcing bolt and the front lower surface of which are fixed with a rubber friction pad with friction texture, the connection between the alloy reducer and the external pipe is tighter and the positioning is more accurate. This avoids problems such as misalignment, loose connection and deformation of components caused by over-tightening of bolts during installation, and achieves a stable and reliable connection between the pipe fitting and the external pipe, reducing the later maintenance cost.

[0013] 2. In this utility model, a circular mounting plate containing five evenly distributed circular mounting holes is fixed to the inner wall of the alloy reducer shell. The circular mounting plate is connected to a circular connecting pipe. A triangular support block is fixed to the side surface of the outer circular connecting pipe. Its outer surface is connected to the inner wall of the shell, and its front surface is connected to the rear surface of the circular mounting plate. Two corresponding inclined platforms are fixed to the front surface of the circular mounting plate. This makes the fluid flow more smoothly in the pipe fitting and the heat exchange tube connection more precise. It avoids the problem of large pressure loss caused by a large amount of eddy current generated at the pipe diameter change and the problem of heat exchange efficiency affected by misalignment of heat exchange tube installation. It achieves uniform distribution of fluid to each heat exchange tube and improves the overall heat exchange performance and operational stability of the heat exchanger. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: an alloy reducer for a multi-row perforated heat exchanger, including a connecting component 1, which includes an alloy reducer housing 101. A reinforcing component 2 is provided on the outer side of the alloy reducer, and the reinforcing component 2 includes six outer bonding strips 201, which are positioned correspondingly. Each outer surface of the outer bonding strip 201 has a threaded groove 202, and a reinforcing bolt 203 is screwed into the threaded groove 202. The rear ends of the six outer bonding strips 201 are fixedly connected to the outer surface of the alloy reducer housing 101. A square limiting block 204 is fixedly connected to the upper rear surface of each of the six alloy reducer housings 101, and the front surface of the square limiting block 204 is movably connected to the rear surface of the reinforcing bolt 203. A rubber friction pad 205 is fixedly connected to the lower front surface of each of the six alloy reducer housings 101, and the lower surface of the rubber friction pad 205 has friction patterns 206. First, the rear ends of the six corresponding outer fitting strips 201 are fixed to the outside of the alloy reducer housing 101. During installation, the inner surface of the outer fitting strip 201 is tightly fitted to the outer wall of the external pipe, providing a uniform support surface for the connection. Then, by tightening the reinforcing bolts 203 in the threaded grooves 202 on the outside of the outer fitting strip 201, the front end of the bolt gradually presses against the outer wall of the external pipe, using the axial pressure of the bolt to lock the fitting to the pipe and prevent the connection from loosening. At the same time, the square limiting block 204 on the upper surface of the rear end of the alloy reducer housing 101 is in contact with the rear surface of the reinforcing bolt 203. When the bolt is tightened to the preset stroke, the square limiting block 204 will stop the bolt from continuing to advance, preventing deformation of the outer fitting strip 201 or damage to the external pipe due to over-tightening. The rubber friction pad 205 on the lower surface of the front end of the housing and the friction texture 206 on its lower surface can increase the static friction between the fitting and the external pipe, preventing relative sliding between the fitting and the pipe during installation, further improving the connection positioning accuracy, and ensuring the sealing and stability of the overall connection structure.

[0023] like Figures 1 to 5As shown, a circular mounting plate 102 is fixedly connected to the inner wall of the alloy reducer housing 101. Five circular mounting holes 103 are evenly distributed on the side surface of the circular mounting plate 102. Circular connecting pipes 104 are fixedly connected to each of the five circular mounting plates 102. Triangular support blocks 106 are fixedly connected to the side surfaces of the two outermost circular connecting pipes 104. The outer surface of the triangular support blocks 106 is fixedly connected to the inner wall of the alloy reducer housing 101, and the front surface of the triangular support blocks 106 is fixedly connected to the rear surface of the circular mounting plate 102. Two inclined platforms 105 are fixedly connected to the front surface of the circular mounting plate 102, and the outer surfaces of both inclined platforms 105 are fixedly connected to the inner wall of the alloy reducer housing 101. The inner wall of the alloy reducer housing 101 is fixed with a circular mounting plate 102, which has five evenly distributed circular mounting holes 103 on its side surface. Each circular mounting hole 103 is adapted to the size of the heat exchange tube of the heat exchanger and can be directly and precisely connected to the circular connecting pipe 104 to ensure that each heat exchange tube can be stably connected to the inside of the fitting and avoid uneven fluid distribution caused by misalignment. The two outer circular connecting pipes 104 are fixed to the side surfaces of triangular support blocks 106. Their outer surfaces are fixed to the inner wall of the alloy reducer shell 101, and their front surfaces are fixed to the rear surface of the circular mounting plate 102. Utilizing the mechanical stability of the triangular structure, they provide bidirectional support for the circular mounting plate 102 and the circular connecting pipes 104, preventing structural deformation after long-term exposure to fluid pressure and temperature changes. At the same time, two positions on the front surface of the circular mounting plate 102 correspond to inclined platforms 105. Their outer surfaces are fixed to the inner wall of the shell. The inclined structure of the inclined platforms 105 can guide the fluid to flow in from the large-diameter end of the shell and smoothly transition along the inclined surface to the circular connecting pipes 104, reducing eddies generated by fluid impact, reducing pressure loss, ensuring efficient and uniform distribution of fluid to each heat exchanger tube, and improving the overall heat exchange efficiency of the heat exchanger.

[0024] Working principle: During the installation phase, the five heat exchange tubes of the heat exchanger are first aligned with the five evenly distributed circular mounting holes 103 on the circular mounting plate 102 on the inner wall of the alloy reducer housing 101, so that the heat exchange tubes are precisely connected to the circular connecting pipes 104 that are fixedly connected to the circular mounting plate 102, completing the initial assembly of the heat exchange tubes and the connecting component 1. At the same time, the external pipe to be connected is fitted onto the corresponding port of the alloy reducer housing 101, so that the outer wall of the pipe is in contact with the inner surface of the six corresponding outer bonding strips 201 of the reinforcing component 2. At this time, the rubber friction pad 205 fixed on the lower front surface of the alloy reducer housing 101 forms an anti-slip contact with the outer wall of the pipe through the friction texture 206 on its lower surface, avoiding relative sliding between the fittings and the pipe during the installation process, and achieving initial positioning. Entering the structural reinforcement stage, the reinforcement bolts 203, which are threaded into the threaded grooves 202 on the outer surface of the outer bonding strip 201, are tightened with tools, so that the reinforcement bolts 203 are pushed axially along the threaded grooves 202 until the front end of the bolt presses against the outer wall of the external pipe. When the bolt is tightened to the preset stroke, the square limiting block 204 fixed on the upper rear end of the alloy reducer housing 101 makes contact with the rear side of the reinforcement bolt 203 through its front side surface, preventing the bolt from being pushed further in, thus preventing over-tightening that could deform the outer bonding strip 201 or damage the external pipe. Finally, through the coordinated pressure of the six reinforcement bolts 203, the pipe fitting and the external pipe form a tight and firm connection structure, ensuring the sealing performance and structural stability during long-term use. During the fluid flow and heat exchange stage, the fluid inside the heat exchanger flows in from the large-diameter end of the alloy reducer shell 101, first contacting the two corresponding inclined platforms 105 fixed on the front surface of the circular mounting plate 102. Through the inclined guiding structure of the inclined platform 105, the fluid is smoothly guided to the circular connecting pipes 104, avoiding direct impact on the inner wall of the pipe and the generation of eddies. At the same time, the triangular support blocks 106 fixed on the side surfaces of the two outer circular connecting pipes 104 provide mechanical support for the circular mounting plate 102 and the circular connecting pipes 104 through the double fixation of their outer surface to the inner wall of the alloy reducer shell 101 and their front surface to the rear surface of the circular mounting plate 102, preventing structural deformation caused by changes in fluid pressure and temperature. Finally, the fluid guided by the inclined platform 105 enters each circular connecting pipe 104 evenly and is distributed to the corresponding heat exchange tubes through the circular mounting holes 103, achieving efficient and uniform distribution of the fluid and ensuring the overall heat exchange efficiency of the heat exchanger.
