Shanghai Institute of Centrifugal Machinery Divergent Thinking to Find the Point of Economic Growth

One side is the sludge treatment in the river channel, and the other is the recycling of photovoltaic battery cutting waste - two “eight poles can not hit” field, but they are all favored by Shanghai Centrifugal Machinery Research Institute Co., Ltd. and become the company’s new economic growth. point.

The use of divergent thinking to find the market is an important experience for the up-and-coming innovation consciousness to promote the development of the company. Qu Yinkai, general manager of the institute, said: "The ultimate goal of technological innovation is to improve market competitiveness. The idea of ​​getting away from the transformation and development is to make technological innovation a key to expanding the market."

Recently, the largest domestic centrifugal dewatering machine independently developed by the institute has been successfully tested in river silt treatment, and the stand-alone treatment capacity has reached 220 cubic meters per hour, far exceeding the expected process indicators. It is understood that before the well-known foreign centrifuge manufacturers to China's key technology blockade, rotary drum diameter of 800 mm above the centrifugal dehydration machine unheard of in the domestic market, a large centrifugal dewatering machine price even more than 10 million yuan. This time, on the LW900 river silt special centrifuge, the diameter of the drum reached 900 mm, breaking the long-term monopoly of foreign large-scale centrifugal dewatering machines.

Not only that, LW900 centrifuge also opened up new space for centrifuge applications - the first in the country to enter the field of sludge treatment. As the leader in the centrifugal dewatering machine industry in China, the centrifugal dewatering machine of the Shangli Group has long been a “calling ring” product in the sewage treatment industry. However, the quality of sewage and waterways is different. The former has a solid concentration of 1% to 5%, while the latter has a solid concentration of 10% to 20%. "From a technical point of view, the requirements of the two are completely different, but we do not have rules in our thinking." Qu Yankai said. With its own technological advantages, Shangshang successfully achieved a new breakthrough.

The LW900 Centrifuge can inhale sewage and sludge, and internally realizes "slurry water separation". Finally, the sludge squeezes out of the pipeline just like the kneaded dough. After using this kind of machinery, the dredging of the river channel does not need to adopt the traditional method of cofferdam construction. Instead, it can be completely closed to complete the operation, which not only ensures the clean and healthy operation environment, but also saves energy consumption compared with the traditional sludge dewatering process. At present, a number of large-scale waterway management companies and design institutes in China have found their intention to purchase and seek technical cooperation.

Entering the field of micro-powder is yet another masterpiece of divergent thinking. According to reports, high-purity crystal silicon wafers need to be cut when preparing solar cells. Currently, liquid mortar cutting methods are used in various countries in the world. Some of the broken silicon carbide particles remain in the spent sand and can be recycled. Therefore, the recovery of silicon carbide has also become an important way for many photovoltaic companies to reduce costs and enhance market competitiveness. At present, the domestic online recycling market for silicon carbide is basically monopolized by Japanese companies, and the cost of introducing a set of equipment is as high as 12 million yuan.

The Shangqiu Institute has acutely discovered this emerging market: Is it not possible to separate silicon carbide from waste sand using centrifugal principles? As a result, they immediately organized scientific research personnel to carry out technological research. We have finally developed a two-stage centrifuge that can separate 6-micron and higher-silicon carbide particles from waste sand. The price is cheap, and the output reaches 1.5 times that of Japanese equipment. Qunian Kai told reporters that when the centrifuges and Japanese equipment used in the factory were used in the same workshop of customers, the attitude of Japanese suppliers was dismissed from the beginning, and later they took a closer look. Attitudes occurred within half an hour. A big change of 180 degrees.

Nowadays, the products of the Shangyou Group have entered the fields of micropowder, chemical industry, alcohol, oil fields, food, etc., and have gradually entered the markets of Malaysia, the Philippines, Spain, India, Germany, Brazil, Vietnam, Bangladesh, Australia, etc. International market development.
