Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery equipment, specifically to a waste heat recovery mechanism for chemical equipment. Background Technology

[0002] Heat exchange pipes are widely used in many areas of industrial production and daily life. However, during operation, these pipes face serious scale buildup problems.

[0003] Water flowing through pipes often contains mineral ions such as calcium and magnesium. When heated, these ions change in solubility and precipitate on the pipe surface, forming scale. Simultaneously, other impurities in the water also contribute to this process, accelerating scale growth. Scale has low thermal conductivity; its accumulation on pipe surfaces significantly reduces heat transfer efficiency, increasing energy consumption. Furthermore, as scale thickens, it reduces the pipe's flow area, and in severe cases, can clog pipes, disrupting the normal operation of the heat exchange system.

[0004] Currently, some shell-and-tube heat exchangers require cleaning of the outer surface of the heat exchange tubes after prolonged use. Traditional cleaning methods require disassembling the shell-and-tube heat exchanger, which is time-consuming and labor-intensive, greatly reducing the cleaning efficiency of shell-and-tube heat exchangers. Utility Model Content

[0005] In view of this, the present invention provides a waste heat recovery mechanism for chemical equipment, which can use a cleaning scraper to surround the heat exchange pipe through a connecting component, and use a cylinder to drive the cleaning scraper to move on the heat exchange pipe to remove impurities and scale adhering to the surface of the heat exchange pipe.

[0006] To solve the above-mentioned technical problems, this utility model provides a waste heat recovery mechanism for chemical equipment, including a heat exchange pipe for heat transfer of materials within the pipe. A cleaning scraper is slidably mounted on the heat exchange pipe to remove scale and prevent loss of heat exchange efficiency. A lifting component is located on one side of the cleaning scraper to move the scraper up and down on the heat exchange pipe, cleaning the scale. A moving component is connected to the bottom of the lifting component to facilitate the movement of the cleaning scraper to clean scale at different locations. A connecting component is provided on the cleaning scraper to ensure the scraper completely surrounds the heat exchange pipe, facilitating the complete removal of scale.

[0007] The cleaning scraper has a groove in the middle, which facilitates the movement of the connecting block and allows the cleaning scraper to overlap to clean the heat exchange pipe. The cleaning scraper is made of metal spring sheet, and the connecting block is slidably installed in the groove. The connecting block is used to drive the cleaning scraper to move up and down and is used to connect with the cylinder.

[0008] The lifting assembly includes a cylinder connected to the moving assembly. The cylinder is used to drive the connecting block to move up and down, and the cylinder output end is connected to the connecting block.

[0009] The moving component includes a base plate, which is used to connect a support cylinder. The cylinder is connected to the base surface of the base plate, and casters are connected to the base surface of the base plate. The casters are used to move the base plate.

[0010] The connecting assembly includes a first boss on one side of the cleaning scraper, the first boss being used to connect a threaded rod, a round hole inside the first boss being used to limit the other end of the cleaning scraper, a through hole matching the cleaning scraper being provided below the round hole, the through hole being connected to the round hole, a threaded rod being rotatably provided inside the round hole, the threaded rod being used to drive the other end of the cleaning scraper to move.

[0011] The other end of the cleaning scraper is provided with multiple slots that match the threaded rod. The slots are used to cooperate with the threaded rod so that the cleaning scraper can overlap when it is opened and closed. The other end of the cleaning scraper is slidably disposed in the through hole, and the threaded rod is engaged with the slot.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. Bend the cleaning scraper to connect the connecting components. By placing one end of the cleaning scraper into the through hole and rotating the threaded rod, the threads on the threaded rod drive the groove on the cleaning scraper to move so that the cleaning scraper fits against the surface of the pipe.

[0014] 2. The cylinder output end drives the connecting block to move up and down, and the connecting block drives the cleaning scraper to move up and down. The scale on the pipe is removed by the up and down movement of the cleaning scraper driven by the connecting block.

[0015] 3. The casters drive the base plate, which in turn moves the moving assembly to move the cleaning scraper to the side of the pipe that needs cleaning. The cleaning scraper is then placed on the side of the pipe that needs cleaning. The cleaning scraper has grooves that allow it to move left and right on the connecting block to accommodate pipes of different diameters. Attached Figure Description
