[0002] Shell and tube heat exchanger is a common heat exchange equipment used to transfer heat between fluids. Shell and tube heat exchanger consists of a tube bundle and a shell. Shell and tube heat exchanger will accumulate dirt and sediment during use, which will reduce heat exchange efficiency and increase energy consumption, so it needs to be taken out and cleaned regularly before it can continue to be used.

[0003] At present, the method of taking out the shell and tube heat exchanger is mostly to use a conveyor wheel to move it out from the inside of the equipment, and then remove it, so that the staff can clean the inside of the shell and tube heat exchanger and remove the dirt for use.

[0004] Although the above method can transport the shell and tube heat exchanger out of the equipment, the shell and tube heat exchanger is placed on a conveying wheel and moved. Due to its heavy weight, it is easy to deviate during the movement, causing the shell and tube heat exchanger to fall from the conveying wheel, causing damage to the shell and tube heat exchanger and affecting its use. Therefore, we propose an automatic conveying device for shell and tube heat exchanger tube bundles to solve the above problem. Utility Model Content

[0026] Example

[0027] Reference Figure 1-Figure 4 The utility model provides a technical solution: an automatic conveying device for a tube bundle of a shell and tube heat exchanger, comprising a processing table 1 and a limiting mechanism 3, the bottom of the processing table 1 is fixedly connected to a support rod 2, the limiting mechanism 3 comprises a conveyor belt 31, the upper surface of the processing table 1 is fixedly connected to a vertical plate 311, the inner side of the vertical plate 311 is provided with the conveyor belt 31, a limiting plate 32 is fixedly installed on the outer surface of the conveyor belt 31, and a rubber pad 33 is fixedly installed on one side of the limiting plate 32.

[0028] In a preferred embodiment, three vertical plates 311 are provided, all of which are fixedly mounted on the upper surface of the processing table 1 to form an open rectangle. The device limits the conveying of the tube bundle of the shell and tube heat exchanger through the conveyor belt 31, so that the tube bundle of the shell and tube heat exchanger moves in a straight line. Therefore, three vertical plates 311 are fixedly mounted on the upper surface of the processing table 1, and the conveyor belt 31 is installed on the inner side of the vertical plates 311, so that the conveyor belt 31 can be used stably, thereby stably transporting the tube bundle of the shell and tube heat exchanger.

[0029] In a preferred embodiment, the inner side surface of the vertical plate 311 is rotatably connected to the round roller 4, and the conveyor belt 31 is arranged on the outer surface of the round roller 4. One end of the round roller 4 is fixedly connected to the rotating rod 5, and one end of the rotating rod 5 is fixedly installed at the output end of the driving motor 6. The device limits the product through the conveyor belt 31, so the round roller 4 is rotatably installed on the inner side of the vertical plate 311, and the conveyor belt 31 is installed on the round roller 4. By driving the round roller 4 to rotate, the movement of the conveyor belt 31 can be controlled, which will limit the product throughout the process to avoid the product from being offset.

[0030] In a preferred embodiment, the upper surface of the conveyor belt 31 is fixedly connected to the positioning plate 7, and the upper surface of the positioning plate 7 is fixedly connected to the limiting plate 32. The limiting plate 32 is set to an inverted trapezoidal shape. In order to improve the limiting effect on the product, the device installs the limiting plate 32 on the upper surface of the conveyor belt 31. The limiting plate 32 shields the side of the product, so that the product can move stably on the driving roller 111.

[0031] In actual use, according to operational needs, an electric telescopic rod 9 can be fixedly connected to one side of one of the vertical plates 311, and the telescopic end of the electric telescopic rod 9 is fixedly connected to the baffle 10. If the product is placed on the driving roller 111, the product can be operated directly on the driving roller 111. Therefore, an electric telescopic rod 9 is installed at the end of the vertical plate 311, and the baffle 10 is pushed to move by the electric telescopic rod 9, thereby limiting the position of the product and placing the product on the driving roller 111 for easy use.

[0032] The device not only limits the position of the product during the conveying process, but also automatically drives the product to move, which is easy to use. A conveying mechanism 11 is installed on the inner side of the vertical plate 311. The conveying mechanism 11 includes a driving roller 111 and a driving plate 112. The inner side of the vertical plate 311 is rotatably connected to the driving roller 111. The driving roller 111 is set to a plurality of numbers and is evenly set at the inner side of the vertical plate 311. The driving roller 111 is set below the conveyor belt 31. The driving plate 112 is fixedly installed at both ends of the driving roller 111. The position of the limiting plate 32 is consistent with the driving plate 112. The position of the plate 112 corresponds to that of the vertical plate 311. One side of the vertical plate 311 is fixedly connected to the load-bearing plate 8. The upper surface of the load-bearing plate 8 is fixedly connected to the driving motor 6. In actual use, a driving roller 111 is rotatably installed on the inner side of the vertical plate 311. The outer surface of the end of the driving roller 111 is fixedly connected to the driving plate 112. A plurality of driving plates 112 are arranged. When the limiting plate 32 passes through the position of the driving plate 112, the driving plate 112 is pushed to rotate, thereby driving the driving roller 111 to rotate, thereby automatically controlling the transportation of the tube bundle of the shell and tube heat exchanger, which is convenient for use.

[0033] Specifically, the working process or working principle of an automatic conveying device for a tube bundle of a shell and tube heat exchanger is as follows: Currently, the method of removing a shell and tube heat exchanger is mostly to use a conveying wheel to move it out from the inside of the equipment, and then remove it, so that the staff can clean the inside of the shell and tube heat exchanger and remove the dirt for use.

[0034] Although the above method can transport the shell and tube heat exchanger out of the equipment, the shell and tube heat exchanger is placed on the conveying wheel and moved. Due to its heavy weight, it is easy to deviate during the movement, causing the shell and tube heat exchanger to fall from the conveying wheel, causing damage to the shell and tube heat exchanger and affecting its use. Therefore, the present device is designed to solve this problem. The external power supply is connected to the external power supply, the shell and tube heat exchanger tube bundle is taken out from the inside of the equipment, and placed on the outer surface of the driving roller 111, and then the driving motor 6 is turned on. The driving motor 6 drives the rotating rod 5 to rotate, which can drive the round roller 4 to rotate, so that the conveyor belt 31 can move normally.

[0035] Since a limiting plate 32 is fixedly installed on the outer surface of the conveyor belt 31, the product can be limited by contacting one end of the limiting plate 32 with the outer surface of the product. At the same time, a rubber pad 33 is fixedly installed on one side of the limiting plate 32. The rubber pad 33 slides with the outer surface of the product to prevent the limiting plate 32 from scratching the outer surface of the product. At the same time, when the rubber pad 33 slides with the outer surface of the product, a certain friction force is generated, which can push the product to move on the driving roller 111, thereby facilitating the transportation of the product.

[0036] In order to increase the moving speed of the product on the driving roller 111, the device drives the limit plate 32 to move by rotating the conveyor belt 31. At this time, the limit plate 32 will push the driving plate 112 to rotate. The driving plates 112 are arranged in a plurality and are evenly arranged at one end of the driving roller 111. Therefore, through the movement of a plurality of limit plates 32, the driving plate 112 can be continuously pushed to rotate, thereby driving the driving roller 111 to rotate, and the movement of the product can be controlled. According to actual use needs, if the product is to stay on the driving roller 111, the baffle 10 is pushed by the electric telescopic rod 9 to block the product. Otherwise, the baffle 10 is controlled to move back, so that the product slides out of the device so that it can be moved to the next place and then operated on.

[0037] It should be noted that the drive motor 6 and the electric telescopic rod 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
