Description

Technical Field

[0001] The utility model belongs to the technical field of microchannel heat exchangers, and in particular relates to a cleaning device for a microchannel heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial processes. In chemical production, they can serve as heaters, coolers, condensers, evaporators, and reboilers, and are widely used. However, in the use of existing technologies, the inventors have discovered the following problems:

[0003] When the heat exchanger is in operation, it will generate a certain amount of heat. The existing technology dissipates heat by setting up vents to make the heat exchanger operate stably. However, during the ventilation process, dust in the air will affect the operation of the heat exchanger. The existing technology filters the dust by setting up filter plates. However, after the filter plates have been used for a certain period of time, a large amount of dust will be contaminated on the side walls of the filter plates. The dust may block the wind and affect the ventilation effect. Usually, the filter plates are replaced or cleaned to remove the dust. However, replacing the filter plates will increase the work cost, and cleaning the filter plates will take up the time and energy of the staff. Therefore, the existing technology has certain disadvantages in use.

The rotation of the second pulley 25 above can drive the second pulley 25 below to rotate through the pulley 27. The two second pulleys 25 can limit the pulley 27. When the pulley 27 is in operation, the connecting block 29 can be driven to move. The movement of the connecting block 29 can drive the first baffle 30 to move. The movement of the first baffle 30 can drive the scraper 28 to move. When the cleaning rod 15 is in contact with the scraper 28, the dust on the side wall of the cleaning rod 15 can be scraped off, and the scraped dust can fall into the cavity of the dust collecting box 21. The dust is limited by the dust collecting box 21. When the push plate 14 is disengaged from the telescopic plate 33, the spring 32 can automatically reset the telescopic plate 33, thereby positioning the cleaning rod 15 below the scraper 28. When scraping dust, the first baffle 30, the second baffle 31 and the telescopic plate 33 can block the dust and prevent the dust from flying around. By setting the gear ratio of the second bevel gear 24 to the first bevel gear 19, the moving speed of the scraper 28 is controlled, so that the position of the cleaning rod 15 corresponds to the scraper 28, the scraper 28 can scrape the dust into the cavity of the dust collecting box 21 within a certain period of time, and through its gear ratio, each time the cleaning rod 15 moves to the position corresponding to the position of the scraper 28, the scraper 28 is always located above.
