June 30, China Machinery Industry Federation organized experts to research and development of China Metallurgical "efficient self-absorption hybrid inverted umbrella aerator", "China Unicom balanced rotary dish high-efficiency aerator" and "less teeth slowdown Diving push mixer "and other three technology products for the national new product identification, the final confirmation of the performance of the first two technical products of the world's leading level," less teeth difference deceleration diving push mixer performance "reached the international advanced level.
According to reports, the development of China Metallurgical days, "efficient self-absorption hybrid inverted umbrella aerator" innovative design of the aerator reducer and hydraulic components (aeration impeller), and the two used for the transmission shaft coupling, the right Combined limit structure and self-locking nuts and other technologies, can reduce the axial and radial reducer more reasonable force, the machine running more stable, small fluctuations in the value of current running, easy maintenance, longer service life. "It mainly solves two major problems. First, under the same working conditions, the oxygenation capacity is increased by 50% or more compared with the international similar aeration technology, and the energy consumption of sewage treatment is reduced by more than 30%. At the same time, the aeration The effective water depth of the biological pool of the machine can be increased to 6 meters, which can reduce the area occupied by the biological pool by 30%, which is beneficial for saving land resources and obvious energy-saving effect. "Cheng Hanfei, chief expert of MCT, said. The technology products currently have eight national patents, including four invention patents, has applied for a U.S. patent. As a major eco-friendly technology and equipment that is encouraged to be developed by the state in 2014, this technology product is mainly used in biochemical treatment processes such as urban sewage treatment plants and industrial wastewater treatment plants. At present, the products transformed from this technology have been successfully applied to Shandong Shouguang, Pingyin and Anhui City, Laian, Tianchang and Fujian Changle and other places of sewage treatment plants, the future will also increase the promotion and application of strength.
It is understood that the "Unicom balanced rotating dish high-efficiency aerator" technology products developed through type bucket bucket-type water heater, effectively overcome the wear and tear on the pumping capacity of water can be collected to enhance water diversion capacity and adjust the balance of capacity Improve, aeration oxygenation and push ability significantly enhanced. The reduction gear mechanism in the technology of "less teeth difference dewatering push-flow mixer" adopts multi-tooth meshing star wheel transmission mode to increase the transmission ratio range, compact structure, large transmission torque and stable operation, and the whole life of the machine reaches 8 years the above.
