Using the latest design, in line with the "three of" standard two rows of large spacing cupola, for the current casting industry commonly used in a cupola, the main structural features for the two rows of vents, row spacing larger, bottom coke burning The formation of two independent combustion zone, by stretching the overheating zone, an increase of hot metal overheating and end coke intense combustion, stable furnace conditions, hot metal temperature, hot metal quality. In accordance with the supply air temperature is divided into cold air, furnace hot air two structures, by mining different temperature air supply to achieve different melting requirements.
Centrifugal blowers are widely used in sewage treatment, smelting blast furnace, coal preparation plant, mine flotation, chemical gas, vacuum and other fields, can also be used to transport other special gases.
1. Compact structure: beautiful appearance, good stability, easy installation and maintenance.
2. Smooth operation: Optimized design of the impeller to reduce the axial force to a minimum, and efficient impeller, and static and dynamic balance correction, the machine running smoothly, without any damping device in the case of bearings Amplitude ≤0.04mm.
3. Low noise: blower operation, without any mechanical friction, the use of a reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.
4. Oil-free machinery: Blower bearings with grease lubrication, bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings.
5. Impeller: Impeller with a special compound linear, reducing internal leakage and improve the volumetric efficiency.
6 easy to adjust: the inlet valve to regulate flow, the outlet valve to regulate the pressure.
7. Drive: usually using a two-pole asynchronous motor, you can also use four-pole motor drive. Depending on the user grid, different voltage motors can be used.
8. Sealing: In addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks.
9. Cooling: exhaust bearing housing has two structures, air-cooled and water-cooled, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.
10. Bearing temperature control alarm: fan accessories with temperature control box, connected to the bearing through the PT100 resistance, when the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.
11. Transmission: a coupling drive, belt drive, gearbox drive three. According to different equipment and technology, choose a different transmission

The University of Science and Technology of China, Pan Jianwei and Lu Chaoyang, collaborated with Xu Xiaodong of the University of Washington and Yao Wang of the University of Hong Kong to discover non-classical single-photon emission in the graphene-only monoatomic semiconductor material for the first time in the world, connecting quantum optics and two-dimensional materials. Two important areas have opened the way to new light quantum devices. The work was published online on May 5th in Nature·Nanotechnology. In the same period, the “News Perspective†column commented that the work “opened up a new field of researchâ€. 
Since the successful preparation of graphene (ie, monoatomic carbon) by scientists in 2004, the physical connotation and superior properties of this material have triggered an external upsurge in basic and applied research. The world's first mass-produced graphene mobile phone developed by China this year not only has high-definition picture, but also has a longer battery life. In recent years, military powers have used graphene instead of Kevlar, aramid and other materials to set up new armor protection equipment; Chinese scientists have made progress in the study of graphene electronic skin. Not long ago, Chinese scientists broke through the difficult problem of industrial production of graphene, and it took only one hour to prepare single-layer graphene. However, due to the lack of energy gap in the electronic structure of graphene, its application in optoelectronic devices is limited.
However, the novel graphene-like material "monoatomic transition metal sulfides" (such as MoS2, WSe2, etc.) with direct band gaps have attracted attention for their unique optoelectronic properties. It is only before that all the research on the two-dimensional materials of monoatomic layers in the world has focused on the field of classical optics. Quantum optical phenomena such as photon anti-bunching have not been observed experimentally.
University of Science and Technology of China Pan Jianwei and Lu Chaoyang collaborated with Xu Xiaodong of the University of Washington and Yao Wang of the University of Hong Kong. It was found that atomic defects in the two-dimensional single atomic layer of tungsten selenide (WSe2) can bind excitons and become nonclassical single photon emission. "Single-atom-based single-photon devices are not only conducive to photon reading and control, but also easily fabricated and implemented in conjunction with other optoelectronic device platforms," ​​compared to other single-photon systems.
The youngest academician, at the age of 27, was selected as one of the "Top Ten Scientific and Technological Progress of the Year". At the age of 31, he resolutely returned to China to set up his own laboratory to help China lead the world in the frontier science and technology of quantum communication... In recent years, in Hefei Working for Pan Jianwei is one of the most dazzling technology stars in China and is considered to be one of the closest Chinese to Nobel.
Lu Chaoyang, Ph.D., University of Cambridge, UK, Professor, University of Science and Technology of China. For the first time in the world, the realization of six-photon entanglement, eight-photon entanglement and ten-bit super-entanglement has refreshed two world records in the field of multiphoton entanglement and optical quantum computing, and was selected twice in the annual progress of China's science and technology. news.
This research means that efficient optical quantum information processing lines can be realized. The theory also shows that scientists can achieve quantum control of the single-electron spin-valley coupling degree of freedom by controlling the electric field, "the future will be applied to the study of fault-tolerant quantum computing."
In fact, the prospective field of quantum regulation based on single-atom layers has become the focus of international competition. The research results of Pan Jianwei's team were published online in Nature and Nanotechnology on the 5th. Three independent research teams in Europe and the United States, such as the National Laboratory of Strong Magnetic Fields, also had similar research results, but later than the Chinese team contributed.
It is worth mentioning that Pan Jianwei's team has achieved a number of achievements in the systematic research of scalable optical quantum information processing technology, including the realization of the first atomic layer semiconductor quantum device and the quantum artificial intelligence algorithm experiment in the world, in the field of optical quantum information. Maintaining an international leading position.
