Description

Technical Field

[0001] The utility model relates to the technical field of large-flow heat exchangers, and specifically to a double-inlet and double-outlet interface structure for a large-flow heat exchanger. Background Technique

[0002] Due to the design working conditions, sometimes a large-flow heat exchanger is required. By increasing the pipe length, quantity, etc. of the heat exchanger, the heat transfer area can be increased. Such a heat exchanger is often large in size, so its corresponding pipe interfaces are also made very large, such as above DN150. The processing of large-diameter pipes is difficult, and the combination of large-diameter pipes with single inlets and outlets will cause uneven liquid separation, affecting the heat transfer effect. Content of the Utility Model

[0003] The purpose of the utility model is to provide a double-inlet and double-outlet interface structure for a large-flow heat exchanger to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A double-inlet and double-outlet interface structure for a large-flow heat exchanger, including:

[0005] An inlet pipe and an outlet pipe installed at the end of the heat exchanger. The inlet pipe and the outlet pipe include a main pipe body and two interfaces fixedly connected to the outer side of the main pipe body;

[0006] A flow splitting component. The flow splitting component is placed inside the main pipe body. The flow splitting component includes an adjusting cover that can be adjustably installed at the end of the main pipe body. A liquid separation plate located between the two interfaces is provided at the bottom of the adjusting cover for liquid separation and cleaning the inner wall of the main pipe body.

[0007] Preferably, the interface includes a first interface and a second interface, and both the second interface and the first interface are fixedly connected to one side of the main pipe body.

[0008] Preferably, a sewage discharge pipe is fixedly connected to one side of the bottom of the main pipe body, and a valve is provided in the middle of the sewage discharge pipe.

[0009] Preferably, a driving block for cooperating with a tool to rotate the adjusting cover is fixedly connected to the top of the adjusting cover.

[0010] Preferably, an external thread is provided on the outer side of the adjusting cover, and an internal thread matching the external thread is provided inside the main pipe body.

[0011] Preferably, a sealing plug is fixedly connected to the bottom of the adjusting cover through a metal rod, a connecting rod is fixedly connected to the bottom of the sealing plug, and the liquid separation plate is fixedly connected to the bottom of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the double-inlet and double-outlet interface and the liquid separation plate in the flow splitting component, the liquid flow is made more reasonable, avoiding uneven liquid separation caused by a single interface and a large-diameter inlet and outlet pipe. It can effectively separate the liquid, ensure the uniform flow of the fluid in the main pipe body, and thus improve the heat exchange efficiency. When it is necessary to clean the inner wall of the main pipe body, the adjusting cover can be simply screwed out and connected to the liquid separation plate through the extension rod, so as to facilitate the cleaning of the inner wall and the maintenance cost is relatively low.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1 、 2 As shown in FIGS. 3 and 4, the present utility model provides a technical solution: A double-inlet and double-outlet interface structure for a large-flow heat exchanger, including: a liquid inlet pipe 1 and a liquid outlet pipe 2 installed at the end of the heat exchanger. The liquid inlet pipe 1 and the liquid outlet pipe 2 include a main pipe body 11 and two interfaces welded to the outside of the main pipe body 11; a flow splitting component is arranged in the main pipe body 11. The flow splitting component includes an adjusting cover 5 threadedly connected to the end of the main pipe body 11. A liquid separation plate 9 located between the two interfaces is provided at the bottom of the adjusting cover 5 for liquid separation and cleaning the inner wall of the main pipe body 11.

[0020] It should be noted that the liquid inlet pipe 1 and the liquid outlet pipe 2 of the present utility model are respectively connected to the inlet and outlet of the heat exchange pipes of the heat exchanger. According to the situation, the rotation adjustment cover 5 adjusts the position of the adjustment cover 5 inside the main body 11. By driving the liquid separation plate 9 to rise and fall through the adjustment cover 5, the two interfaces are separated, making the liquid flow more reasonable and the liquid separation more uniform. The interfaces are connected to the cold water source, and cold water enters the heat exchange pipes through the interfaces and enters the heat exchanger for heat exchange. After the heat exchange is completed, it is discharged through the liquid outlet pipe 2. When it is necessary to clean the inner wall of the main body 11, the adjustment cover 5 is screwed out and then connected to the liquid separation plate 9 through the extension rod. The liquid separation plate 9 scrapes up and down inside the main body 11 to clean the inner wall.

[0021] Please refer to Figure 1 、 2 As shown in FIGS. 3, the interfaces include a first interface 3 and a second interface 10, and both the second interface 10 and the first interface 3 are fixedly connected to one side of the main body 11.

[0022] It should be noted that the first interface 3 and the second interface 10 of the present utility model are arranged vertically and are installed near the middle of the two, which is convenient for liquid diversion. Moreover, the first interface 3 and the second interface 10 on the outer sides of the liquid inlet pipe 1 and the liquid outlet pipe 2 are staggered from each other, so as to facilitate the installation of the connecting pipes.

[0023] Please refer to Figure 1 、 2 As shown in FIGS. 3, a sewage discharge pipe 4 is fixedly connected to one side of the bottom of the main body 11, and a valve is provided in the middle of the sewage discharge pipe 4.

[0024] It should be noted that when cleaning the main body 11 of the present utility model, the valve on the outer side of the sewage discharge pipe 4 can be opened, and the internal impurities can be flushed out by water.

[0025] Please refer to Figure 3 、 4 As shown in FIGS., a driving block 6 for cooperating with a tool to rotate the adjustment cover 5 is fixedly connected to the top of the adjustment cover 5. External threads are provided on the outer side of the adjustment cover 5, and internal threads matching the external threads are provided inside the main body 11. A sealing plug 8 is fixedly connected to the bottom of the adjustment cover 5 through a metal rod, and a connecting rod 7 is fixedly connected to the bottom of the sealing plug 8. The liquid separation plate 9 is fixedly connected to the bottom of the connecting rod 7.

[0026] It should be noted that the present utility model separates the adjustment cover 5 from the sealing plug 8 through a metal rod to prevent the sealing plug 8 from contacting the internal screw during the adjustment process. The hexagonal driving block 6 is driven by a wrench, and the driving block 6 drives the adjustment cover 5 to rotate. Under the action of the thread, the adjustment cover 5 moves up and down. The adjustment cover 5 drives the sealing plug 8 to move inside the main body 11, and the sealing plug 8 drives the liquid separation plate 9 to move through the connecting rod 7. The internal part of the main body 11 is separated and diverted through the liquid separation plate 9, ensuring that water can enter and exit evenly through the first interface 3 and the second interface 10.
