Xinhua News Agency, Tianjin, April 20 (Reporter Yin Siyuan, Song Rui) Walking into the production workshop of Tianjin Detong Electric Co., Ltd., engineers are stepping up the commissioning of the intelligent coal preparation industrial Internet cloud platform independently developed by the company.
"Intelligent coal preparation is an important way for the coal industry to transform its development mode, optimize its production structure and improve its economic benefits. Mu Guangbin, deputy chief engineer of Tianjin Detong Electric Co., Ltd., said that heavy medium coal preparation is an important part of clean coal washing, and it is a gravity coal separation method with a density between coal and gangue as a medium to achieve separation. Due to the change of coal quality of raw coal, the containment control operator needs to continuously adjust the density of the heavy medium suspension according to the results of product testing, but there is an error in the product detection time lag and detection accuracy, so that the containment control adjustment index is often in a correction state.
"The platform comprehensively analyzes and predicts the quality of the selected coal, process parameters, operating data and product quality, and obtains the optimal recommended sorting density. Mu Guangbin introduced, "Through the fine regulation and control of the production process through the intelligent cloud platform, the annual refined coal yield of coal mining enterprises can be increased by 0.5% to 1%, and it is expected to create tens of millions of yuan more benefits per year." ”
Detong Electric's focus on the green and intelligent transformation of the coal industry is a microcosm of the development of Tianjin Xiqing Economic and Technological Development Zone (hereinafter referred to as "Xiqing Economic and Technological Development Zone"), where the company is located, in recent years.

Driving in the park, Saida Emerging Industrial Park, Electronic City Rubik's Cube, Artificial Intelligence Industrial Park and other commercial buildings stand next to each other, and the just-completed Saida Smart Parking Building, Kanghui Hospital and other supporting projects bring new convenience to the life of office workers in the park.
Xiqing Economic and Technological Development Zone was established in 1992 and officially upgraded to a national development zone with the approval of the State Council in 2010. Jia Tao, assistant general manager of Tianjin Xiqing Economic Development Group Co., Ltd., said that in recent years, Xiqing Economic Development Zone has concentrated its efforts in the direction of high-end, intelligent and green development. Up to now, the park has introduced nearly 6,000 enterprises, including 48 of the world's top 500 enterprises, with an annual industrial output value accounting for about half of Xiqing District's total tax revenue and more than one-third of the total tax revenue of Xiqing District.
While focusing on improving the quality of high development, the park has built a characteristic industrial cluster for small and medium-sized enterprises, which has become an important "magic weapon" for the enterprises in the park to continue to improve the quality and efficiency of the industry from "brilliant at the point" to "full flowering".
Jia Tao said that the park draws a regional industrial map, sorts out the blank spots of the industrial chain, and carries out precise investment promotion. In view of the characteristics of more mining equipment production enterprises in the park and a wide range of fields, the industrial chain of this kind of industrial chain is in-depthly combed, and the archives of key enterprises and key enterprises are established, and the supporting relationship between key enterprises is "according to the map", and the supporting industrial chain of the mining industry is gradually improved. By the end of 2023, there will be 49 key mining equipment enterprises in the park, with an output value of nearly 6 billion yuan.
Under the policy support and market guidance, the cooperation between enterprises is getting closer and closer, the industrial chain is gradually improving, and a mining equipment intelligent manufacturing industrial cluster that "cannot be dismantled, moved, or crushed" is "stretching its branches". In 2023, the mining equipment intelligent manufacturing industrial cluster of Xiqing Economic and Technological Development Zone was successfully selected into the list of characteristic industrial clusters of municipal small and medium-sized enterprises in Tianjin in 2023.
"The vigorous development of the mining equipment intelligent manufacturing industry in the park has brought new development opportunities for enterprises. Zhao Weibin, deputy general manager of Aorui (Tianjin) Industrial Group Co., Ltd., said.

Although it is the traditional off-season of the coal industry, the new smart factory of Aorui (Tianjin) Industrial Group Co., Ltd. is still in full swing, with the robotic arm flying up and down, and the parts and components are automatically processed.
Aorui (Tianjin) Industrial Group Co., Ltd. is a large-scale mining equipment manufacturing enterprise, since 2006 settled in Xiqing Economic Development Zone, has gradually developed into a high-tech enterprise with nearly 500 employees and an annual output value of 600 million yuan. Zhao Weibin, deputy general manager of the company, said that compared with the same period in previous years, the output value of the company in the first quarter of this year has increased steadily, and "orders have not been broken."
Business feelings coincide with macro data. According to the economic data of Tianjin in the first quarter, the added value of industrial enterprises above designated size in Tianjin increased by 5.8% year-on-year in the first quarter, 2.1 percentage points faster than that of the previous year. Among them, the added value of high-tech manufacturing increased by 8.6 percent, 2.8 percentage points faster than that of industries above designated size.
"At the beginning of its establishment, the park was only 2 square kilometers, and now the actual development area is nearly 30 square kilometers. Jia Tao said with emotion that after more than 30 years of construction, Xiqing Economic and Technological Development Zone has built a "5+2" modern industrial system dominated by five advanced manufacturing industries, including electronic information, automobiles and parts, high-end equipment manufacturing, biomedicine, and high-end daily necessities, and driven by strategic emerging industries and modern service industries.
"We will continue to play the 'innovation card' and 'reform chess', and continue to move towards the goal of 'first-class national development zone'. Li Guangzhe, general manager of Tianjin Xiqing Economic Development Group Co., Ltd., said.
