Description

Technical Field

[0001] The utility model relates to dyeing and finishing equipment, in particular to a cleaning ball. Background Art

[0002] Throughout the dyeing and finishing process, the fabrics undergo high-temperature drying, depending on the specific processing requirements. During the drying process, the chemical fiber oil, vegetable oil, and lint in the fabrics will leave the fabrics and be mixed into the high-temperature ovens in the drying room. These oils, vegetable oils, and lint must be promptly discharged through the exhaust ducts.

[0003] To utilize the heat contained in the hot exhaust gas from the exhaust duct, a waste heat recovery device is typically designed into the exhaust duct. This device houses several heat exchange tubes, with the hot exhaust gas passing through the middle and fresh, low-temperature air passing through the outside. This creates a temperature difference between the inner and outer walls of the heat exchange tubes. According to the second law of thermodynamics, heat always transfers from a high-temperature object to a low-temperature object. Therefore, the hot exhaust gas in the middle of the heat exchange tubes transfers its temperature to the fresh, low-temperature air outside. This fresh, low-temperature air is then heated and pumped into the drying room for reuse, achieving the purpose of waste heat recovery. However, hot exhaust gas containing chemical fiber oil, vegetable oil, and lint will condense and adhere to the inner walls of the heat exchange tubes after being discharged. Therefore, the inner walls of the heat exchange tubes must be regularly shut down and cleaned. If not cleaned promptly, the mixture of oil and lint remaining on the inner walls of the heat exchange tubes can easily cause fires and affect heat exchange efficiency.

[0004] Existing methods for cleaning the inner walls of heat exchange tubes mostly involve periodically spraying high-temperature water, periodically shutting down the machine, and manually cleaning the heat exchange tube assembly. This is cumbersome, and the high-temperature water spraying is ineffective, affecting heat exchange efficiency. Alternatively, a water curtain filter or filter screen is installed before the hot exhaust gas enters the heat exchange tube assembly. However, the filter screen must be regularly removed for cleaning, and the water curtain filters out impurities, which lowers the temperature of the hot exhaust gas and prevents efficient waste heat recovery. Therefore, there is an urgent need to develop a more efficient heat exchange tube inner wall cleaning device. Utility Model Content

[0005] The purpose of the utility model is to provide a cleaning ball.

[0006] The technical solution for achieving the purpose of the utility model is: a cleaning ball, which includes a cylindrical cleaning ball body, a rope threading hole is opened in the center of the cleaning ball body along its center line, and the cleaning ball body has two or more air passages spaced apart around the circumference of the rope threading hole toward one side of the outer wall of the cleaning ball body, each of the air passages passes through the upper and lower ends of the cleaning ball body, and an inherent elastic scraping ring is concentrically sleeved on the outer wall of the cleaning ball body, and the outer wall of the elastic scraping ring protrudes from the outer wall of the cleaning ball body.

[0007] Furthermore, an annular mounting groove is provided on the outer wall of the cleaning ball body along its circumference, and the elastic scraper ring is embedded in the mounting groove.

[0008] Furthermore, both ends of the cleaning ball body are arched outward to form a truncated cone-shaped protrusion, and the protrusion has a sharp end and a rounded end, and the sharp end is located on the side away from the cleaning ball body.

[0009] Furthermore, the central portion of the cleaning ball body is hollowed out to form a hollow portion, and the hollow portion is communicated with each of the air passages.

[0010] Furthermore, the cleaning ball body is embedded in the pipe to be cleaned, and the elastic scraper ring is in contact with the inner wall of the pipe.

[0011] The cleaning ball realized by the utility model can scrape back and forth on the inner wall of the pipe to be cleaned under the control of the driving mechanism after being threaded with a rope. The air passage is consistent with the flow direction of the hot air exhaust gas, and will not cause obstruction to the circulation of the hot air exhaust gas. Therefore, it can work continuously without stopping the machine, and impurities on the inner wall of the pipe can be scraped off in time. Impurities can also fall from the inner wall of the pipe or the air passage in time and fall out of the pipe to be cleaned, so that the heat exchange tube assembly does not need to be dismantled for cleaning. It has the advantage of not affecting the heat exchange efficiency, solving the pain points of the industry, and is suitable for all requirements for cleaning the inner walls of hot air pipes.
