Description

Technical Field

[0001] The utility model relates to the field of tube-sheet heat exchangers, and more specifically, to a tube-sheet heat exchanger with an extension structure. Background Art

[0002] The tube-sheet heat exchanger is a common heat exchange device widely used in many industrial and commercial fields. Its main function is to achieve heat exchange between two fluids, maintain temperature control of the fluids, and avoid direct contact. The tube-sheet heat exchanger realizes efficient heat exchange through the structural design between the internal tube bundle and the shell, ensuring that heat is effectively transferred from one fluid to another. The two fluids do not come into direct contact during the heat exchange process, reducing the risks of chemical reactions, cross-contamination, or corrosion.

[0003] However, most of the current tube-sheet heat exchangers have the following problems:

[0004] First, for existing tube-sheet heat exchangers, most of the pipes used for connection during operation are in a fixed state. When connecting to other devices for heat exchange, if the angles and positions of the devices are different, the pipes cannot be smoothly connected. It is necessary to rotate the devices for adjustment, which is rather cumbersome as the devices are heavy and inconvenient for extending and adjusting the pipes.

[0005] Second, for existing tube-sheet heat exchangers, during heat exchange, the heat transfer area between the heat exchange pipes and the heat exchange liquid is limited, affecting the heat exchange effect and quality. Moreover, the cooling effect of the heat exchange liquid used for cooling and temperature reduction is poor, and using a cooler to cool the liquid has a poor effect, making it inconvenient to improve the cooling and heat exchange effect.

[0006] Therefore, we make improvements and propose a tube-sheet heat exchanger with an extension structure. Content of the Utility Model

[0007] The purpose of the present utility model is to address the problems of inconvenient extension and adjustment of the pipes and inconvenient improvement of the cooling and heat exchange effect currently existing.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] A tube-sheet heat exchanger with an extension structure to improve the above problems.

[0010] Specifically, this application is as follows:

[0011] It includes an outer pipe sleeve, on which a feed pipe is fixedly connected. A connecting pipe is fixedly connected to the outer pipe sleeve. A pump body is installed on the connecting pipe. A processing box is fixedly connected to the connecting pipe. A refrigerator is installed on the processing box. A temperature guiding frame is fixedly connected to the refrigerator, and the temperature guiding frame is fixedly connected inside the processing box. A partition plate is fixedly connected inside the temperature guiding frame. A flow dividing plate is fixedly connected to the partition plate. A discharge pipe is fixedly connected to the processing box. A return pipe is fixedly connected to the processing box. A valve is installed on the return pipe, and the other end of the return pipe is installed on the outer pipe sleeve. A feeding pipe is fixedly connected to the outer pipe sleeve. A telescopic hose is arranged on the feeding pipe. Flange plates are fixedly connected to the feeding pipe and the telescopic hose. An installation box is arranged on the flange plate. A clamping frame is fixedly connected to the installation box. A spring is fixedly connected inside the installation box. The other end of the spring is fixedly connected to a limiting plate. A clamping block is fixedly connected to the limiting plate. An extrusion plate is fixedly connected to the limiting plate.

[0012] As a preferred technical solution of the present application, the flow dividing plates are equidistantly distributed on the partition plate, and through holes are equidistantly arranged on the flow dividing plates.

[0013] As a preferred technical solution of the present application, the springs are symmetrically distributed on the left and right sides inside the installation box, and the springs and the clamping blocks correspond one by one through the limiting plates.

[0014] As a preferred technical solution of the present application, a liquid distribution box is fixedly connected to the feeding pipe. A heat exchange pipe is fixedly connected to the liquid distribution box, and the cross-section of the middle part of the heat exchange pipe is continuously "S"-shaped.

[0015] As a preferred technical solution of the present application, the side end face of the limiting plate fits with the inner side face of the installation box, and the heat exchange pipes are equidistantly distributed on the liquid distribution box.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] In the solution of the present application:

[0018] 1. An installation box is provided; when transporting liquid for heat exchange treatment, an external pipeline can be used to connect the telescopic hose. The telescopic hose can play a role in telescoping and turning, and can be used to stably connect external equipment. Instead of rotating and adjusting the equipment for use. If the telescopic hose is damaged after long-term use and needs to be disassembled and replaced, the extrusion plates on both sides of the clamping frame can be squeezed to drive the limiting plate inside the installation box to move. When the limiting plate moves, it can squeeze the spring, and at the same time, the clamping block disengages from the flange plate and the clamping frame and retracts into the installation box. After being unobstructed, the installation box and the clamping frame inside the flange plate can be taken out for disassembly, which is convenient for replacing the telescopic hose on the feeding pipe, improving the disassembly and installation efficiency, and can extend the feeding pipe for use with external equipment.

[0019] 2. A heat conduction frame is provided. When performing heat exchange treatment, the liquid to be treated can be transported to the liquid distribution tank through a telescopic hose and a feeding pipe. The liquid is evenly distributed into the heat exchange pipes through the liquid distribution tank. The middle part of the heat exchange pipe is in a continuous "S" shape, which can increase the area of heat exchange treatment. Cooling liquid is added to the outer pipe sleeve through the feeding pipe. The pump body is turned on to transport the liquid to the treatment tank through the connecting pipe. The cooler is turned on to conduct heat through the heat conduction frame. When the liquid passes through the heat conduction frame, the partition plate in the heat conduction frame can separate the liquid for diversion. And under the blocking of the partition plate, the residence time of the liquid in the heat conduction frame can be increased. While transporting the liquid, the liquid can be split by the flow splitting plate for uniform cooling. The cooled liquid can be transported back to the outer pipe sleeve through the return pipe for circulating cooling, improving the uniformity of cooling and smoothly performing heat exchange on the liquid in the heat exchange pipe.

[0033] Example 2:

[0034] The solution in Example 1 will be further introduced below in combination with specific working methods. See the following description for details:

[0035] As Figure 2 shown, as a preferred implementation manner, on the basis of the above manner, further, the flow dividing plates 9 are equally spaced on the partition plate 8, and through holes are equally spaced on the flow dividing plates 9, which can ensure that the through holes on the flow dividing plates 9 can smoothly divide the liquid flow and perform uniform cooling treatment.

[0036] As Figure 3 shown, as a preferred implementation manner, on the basis of the above manner, further, the springs 18 are symmetrically distributed on the left and right sides inside the installation box 16, and the springs 18 correspond to the clamping blocks 20 through the limiting plates 19 one by one, which can ensure that the two clamping blocks 20 can be smoothly clamped in the two flange plates 15 on both sides, and cooperate with the installation box 16 and the clamping frame 17 for stable splicing and limiting.

[0037] As Figure 2 shown, as a preferred implementation manner, on the basis of the above manner, further, a liquid distribution box 22 is fixedly connected to the feed pipe 13, a heat exchange pipe 23 is fixedly connected to the liquid distribution box 22, and the cross-section of the middle part of the heat exchange pipe 23 is in a continuous "S" shape, which can ensure that the heat exchange pipe 23 in a continuous "S" shape can increase the residence time of the liquid in the outer pipe sleeve 1 and perform sufficient heat exchange treatment.

[0038] As Figure 3 shown, as a preferred implementation manner, on the basis of the above manner, further, the side end face of the limiting plate 19 is in contact with the inner side face of the installation box 16, and the heat exchange pipes 23 are equally spaced on the liquid distribution box 22, which can ensure that when the limiting plate 19 moves, it can move smoothly through the support of the inner side face of the installation box 16.

[0039] Specifically, when this sleeve-type heat exchanger with an extension structure is in use: Combining Figures 1-5, when transporting liquid for heat exchange treatment, an external pipeline can be used to connect the telescopic hose 14. The telescopic hose 14 can play a role in telescoping and turning, and can be used to stably connect external devices, avoiding the use of rotating and adjusting devices. If the telescopic hose 14 is damaged after long-term use and needs to be disassembled and replaced, the extrusion plates 21 on both sides of the clamping frame 17 can be squeezed to drive the limit plate 19 in the installation box 16 to move. When the limit plate 19 moves, it can squeeze the spring 18, and at the same time, the clamping block 20 disengages from the flange plate 15 and the clamping frame 17 and retracts into the installation box 16. After being unobstructed, the installation box 16 and the clamping frame 17 in the flange plate 15 can be taken out for disassembly, which is convenient for replacing the telescopic hose 14 on the feed pipe 13, improving the disassembly and installation efficiency, and can extend the feed pipe 13 for use with external devices.

[0040] When performing heat exchange treatment, the liquid to be treated can be transported to the liquid distribution box 22 through the telescopic hose 14 and the feed pipe 13. The liquid is evenly distributed into the heat exchange tubes 23 through the liquid distribution box 22. The middle part of the heat exchange tubes 23 is in a continuous "S" shape, which can increase the area of heat exchange treatment. The cooling liquid is added to the outer pipe sleeve 1 through the feed pipe 2. The pump body 4 is started, and the liquid is transported to the treatment box 5 through the connecting pipe 3. The cooler 6 is started, and temperature conduction is carried out through the temperature conduction frame 7. When the liquid passes through the temperature conduction frame 7, the partition plate 8 in the temperature conduction frame 7 can separate the liquid for diversion. And under the blocking of the partition plate 8, the time for the liquid to stay in the temperature conduction frame 7 can be increased. While transporting the liquid, through the flow dividing plate 9, the liquid can be divided to carry out uniform cooling. The cooled liquid can be transported back to the outer pipe sleeve 1 through the return pipe 11 for circulating cooling, improving the uniformity of cooling and smoothly carrying out heat exchange on the liquid in the heat exchange tubes 23. When discharging the cooling liquid, the valve 12 on the return pipe 11 can be closed, and the discharge pipe 10 on the treatment box 5 can be opened. When the pump body 4 transports the liquid, it can be discharged through the discharge pipe 10 for collection and treatment.

[0041] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the utility model are covered by the scope of the claims of the present invention.
