The characteristics of rope core drill pipe are "three highs and one low", that is, high drilling speed, long life of diamond bit, high time utilization rate, low labor intensity of workers, so it is widely used in geological prospecting, coal field exploration and other fields. Among the whole set of drilling tools, the most important and most valuable is the drill pipe. The quality of the drill pipe is directly related to the use of the advantages of rope core drilling, and is also vital to the accurate acquisition of geological data and the control of drilling costs.
The world's first garbage source sorting machine was successfully developed
For a long time, dealing with urban domestic waste has always been a difficult problem. The data shows that China has an annual output of 114 million tons of garbage. Over the years, the amount of garbage dumped has reached 6 billion tons, and the garbage dump covers an area of ​​more than 500 million square meters, all of which are mainly domestic garbage with serious pollution. Recently, with the successful development of a new type of garbage source sorter, this problem is expected to be solved.
The disposal of domestic garbage is difficult, and it is difficult to classify the technical level at the source. The BZL-1 integrated waste source sorting machine developed by Beijing Zeguang Xinyuan Environmental Protection Technology Co., Ltd. can quickly and automatically separate domestic garbage, achieving a classification processing efficiency of 500 kg per hour, and separating the mixed and transported garbage into kitchen waste. The materials can be directly recycled and plastic bags, so that the domestic garbage of different compositions can be processed in an orderly manner, filling the technical gap in the field of garbage classification at home and abroad.
The Beijing Municipal Administration Commission, China Urban Environmental Health Association, and Beijing Environmental Health Research Institute have conducted field visits and concluded that the machine has high technical content, good classification effect, small floor space, low energy consumption, wide application range, and comprehensive The realization of technology integration and system application has achieved a key breakthrough in the classification of domestic waste sources, with significant promotion and practical value. According to reports, the two-cell trial operation of the aircraft and the biological processor in Beijing showed that the garbage was basically digested on the spot. Experts believe that the advent of the waste sorter has fundamentally broken through the problem of source classification of domestic waste, ensuring rapid classification before deep processing. This technology has been patented, has independent intellectual property rights, and has been certified by provincial new scientific and technological achievements.
