Technical Field
[0001] This utility model belongs to the field of manifold structure technology, specifically relating to an integrated high-pressure manifold box structure. Background Technology
[0002] Currently, heat exchangers are widely used in industries such as petroleum, chemical, metallurgy, power, and machinery. They facilitate heat exchange between high and low temperature fluids, thereby achieving the purpose of heating cold fluids or cooling hot fluids. Shell-and-tube heat exchangers are the most widely used type of heat exchanger. In this type of heat exchanger, the hot and cold fluids flow in the tube side or shell side respectively during operation, achieving indirect heat exchange.
[0003] Shell-and-tube heat exchangers mainly consist of heat exchange tubes and tube sheets for supporting the heat exchange tubes, such as... Figure 4 In the prior art, the ends of the heat exchange tubes extending out of the tube sheet are connected to a manifold to collect the fluid. The manifold has a main pipe and connecting pipes that are connected to the ends of the heat exchange tubes one by one. By welding the connecting pipes to the heat exchange tubes one by one, the fluid in the heat exchange tubes is collected into the main pipe. However, the manifold in the prior art generally welds the main pipe and the connecting pipe together, resulting in many manufacturing processes and weak pressure resistance of the manifold.
[0004] Therefore, it is necessary to propose an integrated high-pressure manifold box structure to solve the above problems. Utility Model Content

[0009] Furthermore, a drainage pipe communicating with the inner cavity of the main pipe is provided on the outer wall of the main pipe. The axis of the drainage pipe is perpendicular to the axis of the connecting pipe and the axis of the main pipe.
[0010] Furthermore, the drainage tube is provided with connecting blocks symmetrically arranged about the axis of the drainage tube on both sides, and the line connecting the two connecting blocks is parallel to the axis of the connecting tube.
[0011] Furthermore, a sliding sleeve is slidably installed on the upper limit of the connecting pipe, and the sliding sleeve is used to connect the heat exchange pipe and the connecting pipe.
[0012] Furthermore, the connecting pipe is provided with a limiting groove, and the sliding sleeve is provided with a slider that cooperates with the limiting groove. The sliding sleeve slides within the limiting groove by the slider.
[0013] Furthermore, the sliding sleeve is provided with a sliding hole that cooperates with the slider. The slider is slidably installed in the sliding hole. Sliding the slider along the sliding hole can cause the slider to slide into or out of the limiting sliding groove.

[0023] like Figures 1-4As shown, this utility model provides an integrated high-pressure manifold box structure, including: a main pipe 1 and multiple connecting pipes 2 arranged side by side along the axis of the main pipe 1, wherein the main pipe 1 and the multiple connecting pipes 2 are connected as one unit.
[0024] In this scheme, the manifold box is connected one-to-one with the heat exchange tubes 4 mounted on the tube sheet 3 of the heat exchanger via connecting pipe 2. The main pipe 1 and connecting pipe 2 are connected as one piece, which is formed by forging, reducing the welding process and improving the pressure bearing capacity of the manifold box structure.
[0025] In one embodiment of the present invention, the main pipe 1 is provided with a flat key 101, and the first ends of the plurality of connecting pipes 2 are connected to the flat key 101 as a whole.
[0026] In this scheme, by setting a flat key 101, the connection between the connecting pipe 2 and the main pipe 1 is made flat, which is conducive to the integral forging of the manifold box and increases the thickness of the connection between the main pipe 1 and the connecting pipe 2, thereby improving the pressure bearing capacity of the connection between the main pipe 1 and the connecting pipe 2.
[0027] In one embodiment of the present invention, a drainage pipe 102 communicating with the inner cavity of the main pipe 1 is provided on the outer wall of the main pipe 1. The axis of the drainage pipe 102 is perpendicular to the axis of the connecting pipe 2 and the axis of the drainage pipe 102 is perpendicular to the axis of the main pipe 1.
[0028] In this scheme, the drainage pipe 102 is vertically installed on the main pipe 1, and the installation position of the manifold box is determined accordingly. Figure 4 When the manifold box is installed in the direction of fluid inlet or outlet, the drain pipe 102 is set vertically downward as the fluid outlet to facilitate fluid flow.
[0029] In one embodiment of this utility model, connecting blocks 103 are provided on both sides of the drainage tube 102 symmetrically arranged about the axis of the drainage tube 102. The line connecting the two connecting blocks 103 is parallel to the axis of the connecting tube 2. The connecting blocks 103 are used to cooperate with the connecting accessories for installing the manifold box to facilitate the installation and positioning of the manifold box. After installation, the connecting blocks 103 are used to limit the position, thereby reducing the pressure on the drainage tube 102.
[0030] In one embodiment of the present invention, a sliding sleeve 201 is slidably installed on the upper limit of the connecting pipe 2, and the sliding sleeve 201 is used to connect the heat exchange pipe 4 and the connecting pipe 2.
[0031] In this scheme, before welding to connect the heat exchange tube 4 and the connecting tube 2, the sliding sleeve 201 is used to cover the heat exchange tube 4 and the connecting tube 2, and the sliding sleeve 201 is staggered, that is, one of the sliding sleeves 201 on two adjacent connecting tubes 2 is covered by the heat exchange tube 4, while the other sliding sleeve 201 on two adjacent connecting tubes 2 is not covered by the heat exchange tube 4, so as to facilitate the welding process. After the welding is completed, the sliding sleeve 201 is removed from the heat exchange tube 4, and the welding process is then carried out again. This scheme ensures the accuracy of the alignment between the heat exchange tube 4 and the connecting tube 2 before welding and the stability during the welding process by setting the sliding sleeve 201.
[0032] In one embodiment of this utility model, the connecting pipe 2 is provided with a limiting groove 202, and the sliding sleeve 201 is provided with a slider 203 that cooperates with the limiting groove 202. The sliding sleeve 201 slides within the limiting groove 202 by the slider 203. The limiting groove 202 is integrally formed by forging, which does not require separate processing and does not affect the manufacturing complexity of the manifold box.
[0033] In one embodiment of the present invention, the sliding sleeve 201 is provided with a sliding hole 204 that cooperates with the slider 203. The slider 203 is slidably installed in the sliding hole 204. Sliding the slider 203 along the sliding hole 204 can cause the slider 203 to slide into or out of the limiting groove 202, thereby facilitating the installation and disassembly of the sliding sleeve 201.
[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
