Description

Technical Field

[0001] This utility model relates to the technical field of cooling equipment structure, and in particular to a heat exchange pipe assembly and a jam cooling device. Background Technology

[0002] Jam processing typically involves high-temperature treatment, requiring cooling to a lower temperature, such as 60-70℃, before subsequent packaging. In existing technologies, jam is generally transported from the initial processing equipment to the subsequent packaging equipment via a conveyor pipe. This requires relatively long pipes to allow sufficient cooling time. To improve cooling efficiency, the conveyor pipe is often designed with a jacket structure, creating an annular space around the main conveyor pipe. Cooling water is then introduced into this annular space, allowing the jam to exchange heat with the cooling water within the conveyor pipe, thus cooling it down. However, while this method achieves relatively efficient cooling within a shorter conveyor pipe, controlling the jam's transport speed to ensure sufficient heat exchange time limits the subsequent packaging efficiency. Therefore, further improvements in heat exchange efficiency are needed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a heat exchange pipeline assembly that solves the problem that the heat exchange efficiency still needs to be further improved in existing technologies.

[0004] According to an embodiment, a heat exchange pipe assembly is provided, comprising an outer pipe and a conveying pipe fixedly disposed within the outer pipe. The inner wall of the conveying pipe has an inner protrusion protruding towards its center, and the conveying pipe also has a connecting hole communicating with the inner protrusion and the outside of the conveying pipe. An inlet pipe and an outlet pipe, respectively located at opposite ends of the outer pipe and communicating with it, are fixedly connected to the outer pipe. Mounting rings are fixedly connected to both ends of the outer pipe, and the two ends of the conveying pipe are also fixedly connected to the two mounting rings. Similar to the prior art, an annular space is formed outside the conveying pipe through the outer pipe. However, this solution further provides an inner protrusion within the conveying pipe, allowing the introduced cooling water to enter the inner protrusion, thereby increasing the heat exchange area of ​​the jam and further improving the heat exchange efficiency. This allows the jam conveying speed to be accelerated to a certain extent, ensuring the normal and efficient operation of subsequent processes.

[0005] Furthermore, the inner protrusion includes multiple sets arranged equidistantly around the perimeter.

[0006] Furthermore, a core tube is coaxially arranged inside the conveying pipe, passing through both ends, and the core tube and the inner protrusion are fixedly connected by multiple connecting rods.

[0007] Furthermore, the inner protrusion includes an arcuate plate extending from one end of the delivery pipe to the other.

[0008] Furthermore, the inner protrusion includes a protrusion arranged along the length of the conveying pipe.

[0009] According to an embodiment, a jam cooling device including the above-described heat exchange pipe assembly is also provided.

[0010] Compared with the prior art, the present invention has the following beneficial effects: An inner protrusion is installed inside the conveying pipe, which is connected to the outer annular space through a connecting hole. This allows the introduced cooling water to pass through the inner protrusion, thereby increasing the heat exchange area of ​​the jam and further improving the heat exchange efficiency. This can speed up the jam conveying speed to a certain extent and ensure that subsequent processes can proceed normally and efficiently. Attached Figure Description

Detailed Implementation

[0012] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , 2As shown, this embodiment provides a jam cooling device, which includes a heat exchange pipe assembly. Similar to existing technologies, this assembly includes a conveying pipe 1, and an outer pipe 2 is fixedly installed outside the conveying pipe 1. Both ends of the conveying pipe 1 and the outer pipe 2 are fixedly connected to mounting rings 3. The inner ring of the mounting ring 3 is connected to the inner wall of the conveying pipe 1. The device is connected to front-end and back-end process equipment through two mounting rings 3. Unlike existing technologies, an inner protrusion 4 protruding towards its center is fixedly installed inside the conveying pipe 1. This inner protrusion 4 has space within it, and the conveying pipe 1 has a connecting hole 5 to connect with the inner protrusion. In addition to the conveying pipe 1, an inlet pipe 6 and an outlet pipe 7 for introducing and discharging cooling water are fixedly connected to the outer pipe 2. The introduced cooling water enters the inner protrusion 4 through the connecting hole 5 (in another scheme, these connecting holes 5 may not be provided, so the inner protrusion 4 can be an integral structure formed by the inner wall of the conveying pipe 1 protruding directly inward, and the cooling water can also enter the inner protrusion 4). This provides a larger heat exchange area in the conveying pipe 1, which can further improve the cooling efficiency of the jam and accelerate the conveying speed of the jam to a certain extent, ensuring that the subsequent processes are carried out normally and efficiently.

[0014] like Figure 3 As shown, in one embodiment, the inner protrusion 4 can be an arc-shaped plate 8 extending from one end of the conveying pipe 1 to the other end, thereby increasing the heat exchange area.

[0015] like Figure 4 As shown, in another embodiment, the inner protrusion 4 includes a protrusion 9 arranged along the length of the conveying pipe 1, thereby increasing the heat exchange area.

[0016] like Figure 1-4 As shown, the inner protrusion 4 can include multiple sets of equidistant surrounding parts, and a core tube 10 coaxial with the conveying pipe 1 can also be fixedly installed inside the conveying pipe 1. The two ends of the core tube 10 extend through the two mounting rings 3 and can also be used to introduce cooling water to provide heat exchange inside the conveying pipe 1, further improving the heat exchange efficiency.

[0017] like Figure 2 As shown, multiple connecting rods 11 can be fixedly connected between the core tube 10 and the inner protrusion 4, which can increase the overall mechanical stability.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
