[0002] An insertion tube heat exchanger is a device used for heat exchange. It separates two fluids through tube walls to achieve the process of transferring heat from one medium to another. It plays an important role in many industrial fields and provides the necessary thermal energy support for various processes.

[0003] In actual use, existing heat exchangers require regular cleaning of the drain port. This is usually done by inserting a tool into the drain port and making a reciprocating motion. However, this method leaves a lot of dirt on the hands, making the working environment too dirty. Therefore, there is a need for an insert-type shell and tube heat exchanger to prevent dirt from the drain port from getting on the hands and to increase the cleanliness of the working environment. Utility Model Content

[0004] The purpose of this utility model is to provide an insert-type shell and tube heat exchanger to solve the problem mentioned in the background art, where existing heat exchangers require regular cleaning of the drain port during actual use. This is usually done by inserting a tool into the drain port and making a reciprocating motion, but this method leaves a lot of dirt on the hands, resulting in an overly dirty working environment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an insertion-type shell-and-tube heat exchanger, comprising:

[0007] Heat exchanger body;

[0008] The unblocking assembly includes a support frame, a fixed frame, a movable block, a connecting frame, a rotating column, a support column, and an inclined column.

[0009] Furthermore, a guide rod is fixed to the upper surface of the movable block, the guide rod is connected through the inside of the fixed frame, a guide plate is fixed to the upper surface of the guide rod, a connecting shaft is fixed inside the connecting frame, and the rotating column is rotatably connected to the outer surface of the connecting shaft.

[0010] Furthermore, a fixing plate is fixed to the outer surface of the other side of the connecting frame, a spring is fixed to the upper surface of the fixing plate, a movable plate is fixed to the upper surface of the spring, and a limit post is fixed to the lower surface of the movable plate.

[0011] Furthermore, it also includes a reinforcement component, which includes a fixing column, a first support plate, a second support plate, and a limiting plate; the fixing column is fixed to the lower surface of the support frame, the first support plate is fixed to the outer surface of the support frame, the second support plate is fixed to the outer surface of the heat exchanger body, the first support plate and the second support plate are in contact with each other, and the limiting plate is fixed to the outer surface of the second support plate.

[0012] Furthermore, a second connecting plate is fixed to the upper surface of the second support plate, the second connecting plate is fixed to the limiting plate, and a first connecting plate is fixed to the lower surface of the limiting plate.

[0013] Furthermore, the first support plate and the second support plate are internally connected by bolts, and nuts are threaded onto the outer surface of the bolts.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This invention utilizes a specially designed unblocking component. When cleaning the drain outlet of the heat exchanger body is required, an upward force is applied to the movable plate, causing the limiting column to disengage from the rotating column. Under the action of the connecting shaft, a rotational force is applied to the rotating column, moving the support column to the bottom of the drain outlet. The force applied to the movable plate is then released, and under the elastic force of the spring, the limiting column springs back into the rotating column. After the drain outlet cover is opened, a reciprocating force is applied to the guide plate, causing the movable block at the bottom of the guide rod to move synchronously. This, in turn, causes the rotating column to reciprocate. Under the action of the inclined column, impurities inside the drain outlet are discharged. This solution prevents dirt from the drain outlet from staining hands, increasing the cleanliness of the working environment.

[0016] Based on the first beneficial effect, when the support frame needs to be installed in the required position with the reinforcement components, firstly, corresponding holes are drilled in the ground, the second support plate is welded to the surface of the heat exchanger body, the support frame is lifted up, the first support plate is attached to the corner of the top of the second connecting plate and the limiting plate, and then a downward force is applied to the support frame to make the surface of the first support plate and the first connecting plate fit together, thereby inserting the fixing column into the required position, inserting the bolt into the first support plate and the second support plate, and fixing the nut on the outer surface of the bolt. Then, cement is poured into the hole. This solution stably fixes the support frame in the required position, thereby making the heat exchanger body more firmly fixed. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-3As shown, this embodiment is an insertion-type shell-and-tube heat exchanger, comprising:

[0030] Heat exchanger body 11;

[0031] The unblocking assembly includes a support frame 21, a fixed frame 22, a movable block 23, a connecting frame 26, a rotating column 28, a support column 294, and an inclined column 295. The support frame 21 is located on one side of the heat exchanger body 11. The fixed frame 22 is fixed to one end of the outer surface of the top of the support frame 21. The movable block 23 is movably connected to the inside of the fixed frame 22. The connecting frame 26 is fixed to the outer surface of the movable block 23. The rotating column 28 is rotatably connected to the inside of the connecting frame 26. The support column 294 is fixed to the upper surface of the rotating column 28. The inclined column 295 is fixed to the inside of the support column 294.

[0032] The support frame 21 serves as the basic platform for the unblocking components, enabling other parts to work effectively together. The fixed frame 22 provides the installation position and guidance for the movable block 23. The movable block 23, through its cooperation with the guide rod 24 and the guide plate 25, controls the rotating column 28, thereby affecting the movement of the support column 294 and the inclined column 295. It is a key component for cleaning the sewage outlet. The connecting frame 26 supports and installs the movable block 23, and in turn supports and installs the connecting shaft 27. The support column 294 is used to support and install the inclined column 295. The inclined column 295, through its inclined design, helps to more effectively discharge impurities inside the sewage outlet, improving cleaning efficiency.

[0033] A guide rod 24 is fixed on the upper surface of the movable block 23. The guide rod 24 is connected through the inside of the fixed frame 22. A guide plate 25 is fixed on the upper surface of the guide rod 24. A connecting shaft 27 is fixed inside the connecting frame 26. A rotating column 28 is rotatably connected to the outer surface of the connecting shaft 27.

[0034] The guide plate 25 enables precise control of the movable block 23, ensuring that the movable block 23 can move along a predetermined trajectory. The guide plate 25 also facilitates the application of pulling force to the guide rod 24. The connecting shaft 27 serves as the rotation center of the rotating column 28, ensuring that the rotating column 28 can rotate in the correct position.

[0035] A fixing plate 293 is fixed on the outer surface of the other side of the connecting frame 26. A spring 292 is fixed on the upper surface of the fixing plate 293. A movable plate 291 is fixed on the upper surface of the spring 292. A limit post 29 is fixed on the lower surface of the movable plate 291. There are two sets of limit posts 29. One set of limit posts 29 is located inside the rotating column 28.

[0036] The fixed plate 293 is used to support and install the spring 292. The spring 292, through its elastic force, allows the limiting post 29 to automatically spring back into the rotating post 28 after the external force is removed. The movable plate 291 facilitates changing the height of the limiting post 29. The limiting post 29 is used to restrict the rotating post 28 to the required position.

[0037] Working principle: When it is necessary to clean the drain port of the heat exchanger body 11, an upward force is applied to the movable plate 291, which drives the limiting column 29 to disengage from the rotating column 28. Under the action of the connecting shaft 27, a rotational force is applied to the rotating column 28, which moves the support column 294 to the bottom of the drain port. The force applied to the movable plate 291 is released. Under the elastic force of the spring 292, the limiting column 29 springs back into the rotating column 28. After the drain port cover is opened, a reciprocating force is applied to the guide plate 25, which drives the movable block 23 at the bottom of the guide rod 24 to move synchronously, thereby causing the rotating column 28 to reciprocate. Under the action of the inclined column 295, the impurities inside the drain port are discharged.

[0038] This step prevents dirt from the drain outlet from getting on your hands, increasing the cleanliness of the work environment.

[0039] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, also includes a reinforcing component. The reinforcing component includes a fixing column 31, a first support plate 32, a second support plate 33, and a limiting plate 34. The fixing column 31 is fixed to the lower surface of the support frame 21, the first support plate 32 is fixed to the outer surface of the support frame 21, the second support plate 33 is fixed to the outer surface of the heat exchanger body 11, the first support plate 32 and the second support plate 33 are in contact with each other, and the limiting plate 34 is fixed to the outer surface of the second support plate 33.

[0040] The fixed column 31 is used to fix the support frame 21 in the required position. The first support plate 32 is used to connect with the second support plate 33, thereby fixing the support frame 21 to the heat exchanger body 11. The limiting plate 34 plays a guiding role, making it convenient to move the first support plate 32 to the required position.

[0041] The second support plate 33 has a second connecting plate 38 fixed on its upper surface. The second connecting plate 38 is fixed to the limiting plate 34. The limiting plate 34 has a first connecting plate 35 fixed on its lower surface.

[0042] The second connecting plate 38 is used to cooperate with the limiting plate 34 and the first connecting plate 35 to accurately position the first support plate 32 to the required installation position.

[0043] A bolt 36 is internally connected to the first support plate 32 and the second support plate 33, and a nut 37 is threaded onto the outer surface of the bolt 36.

[0044] Bolt 36 is used to connect the first support plate 32 and the second support plate 33 together, and nut 37 is used to fix bolt 36 in the desired position.

[0045] Working principle: When the support frame 21 needs to be installed in the required position, firstly, drill the corresponding holes in the ground, weld the second support plate 33 to the surface of the heat exchanger body 11, lift the support frame 21, attach the first support plate 32 to the corner of the top of the second connecting plate 38 and the limiting plate 34, then apply a downward force to the support frame 21 so that the surface of the first support plate 32 and the first connecting plate 35 are attached, thereby inserting the fixing column 31 into the required position, inserting the bolt 36 into the inside of the first support plate 32 and the second support plate 33, rotating and fixing the nut 37 to the outer surface of the bolt 36, and then pouring cement into the hole;

[0046] This step securely fixes the support frame 21 in the required position, thereby making the heat exchanger body 11 more firmly fixed.
