Mechanical Bar Screen
Mechanical Bar Screen is provided with several special-shaped teeth which are assembled on the teeth axis based on certain ordering, forming the sealed teeth chain. The lower part is installed in the water inlet. If the chain wheel rotates directionally with even speed, the whole rake chain will move accordingly. Under such circumstance, the solid sundries attached on the tooth will be separated from liquid and the fluid will low away through the gap. When rake chain arrives at its upper end, each group of rakes will carry on self cleaning by dropping out most of the solid material under gravity and guideline rail, while the rest of the solid will be tidied clean by back running brush.The whole process is carried out continuously and automatically so as to achieve the goal of solid-liquid separation.

South Korea's shipbuilding three strong modern heavy industry, Samsung Heavy Industry and Daewoo Shipbuilding in order to continue to maintain a strong position in the global shipbuilding enterprises, expand the gap with the Chinese shipbuilding industry in the field of technology, recently invested in technology and new product research and development areas , increase research and development efforts.
The goal of Samsung Heavy Industries is to develop into a world-class enterprise. Its annual investment in research and development is around US$100 million. There are research and development and technology research institutes in the country with more than 1,300 technicians. In the first half of this year, Samsung Heavy Industries decided to invest in India to establish its first overseas shipbuilding technology development research institute. In addition to making full use of local IT talents and low production cost resources in India, it also laid the foundation for the future capture of the Indian shipbuilding market. . The Samsung India Shipbuilding Technology Research Institute initially recruited 100 local technicians and will expand to 200-300 or more in the future. According to reports, Samsung Heavy Industries also plans to build ship research institutes in the United States and Russia.
At present, the new types of ships developed by Samsung Heavy Industries include luxury cruise ships, multi-purpose marine oil and gas project equipment ships, super large LNG ships, and merchant ships with ice breaking functions. recent. Samsung Heavy Industries has also undertaken two 31,000-ton passenger and cargo vessels, and the design of a luxury cruise ship with a displacement of 85,000 tons has been completed. Preparations will begin to take orders around 2010. The development and design of the ultra-large 266,000 cubic meters LNG ship has also been completed, and the order was officially received in the first half of the year. In the marine project equipment ship. Samsung Heavy Industries will combine the exploration and well drilling function with the FPSO to develop a marine project equipment ship with comprehensive functions. In terms of icebreaking merchant ships, Samsung Heavy Industries has completed the first 75,000-ton oil tanker with self-breaking capacity, and is currently developing LNG and container ships with self-breaking functions.
Hyundai Heavy Industries is truly the world's first shipbuilding enterprise. Its research and development and design and technical personnel have reached more than 1,800. After recruiting 233 new university graduates and staff in the first half of this year, it will recruit more than 500 in the second half of the year. people. In recent years, Hyundai Heavy Industries has invested more than US$100 million annually in research and development. This year's investment in the R&D and technology sectors reached $185 million. The weakness of Hyundai Heavy Industries is the marine project equipment. Therefore, Hyundai Heavy Industries decided to build the 10th dock in the Ulsan Shipyard, which is the largest dock in the factory. It is possible to build two large FPSOs at the same time. The ship project currently under development by Hyundai Heavy Industries is an ultra-large container ship. The 15000TEU class container ship has been developed and designed to take orders. In the field of LNG ships, Hyundai Heavy Industries is developing long-distance shipping methods for high-pressure storage of natural gas, as well as the elimination of LNG receiving stations on land, and the construction of offshore LNG conversion station terminal facilities for direct gasification of LNG at sea. In terms of marine project equipment. Hyundai Heavy Industries is also developing a comprehensive functional marine oil and gas project equipment ship that integrates exploration, drilling, mining, production and storage functions. At the same time, luxury cruise ships are also a new field of modern heavy industry research and development.
Daewoo Shipbuilding has four R&D institutions, with more than 1,500 R&D and design staff, and an average of 1.4 R&D technicians per 10 employees. The large-word shipbuilding is one of the strongest military workers in the Korean shipbuilding industry. The first generation of submarines of the South Korean Navy, the first-generation destroyers and other naval vessels are all built by large-scale ships, and they are in LNG ships, super-large oil tankers and offshore oil and gas projects. The equipment field has certain advantages. The LNG-RY ship with LNG regasification equipment on board the ship has been put into maritime shipping service; the technology to prevent natural gasification of LNG in the storage compartment of LNG ship has also been successful, and the next step will be commercialized. In the field of marine project equipment. Daewoo Shipbuilding puts the power on the new concept ship: the FPSO has many functions such as drilling, production and mining, storage, etc., and it can be used for one ship. In addition, Daewoo Shipbuilding is also involved in the development and construction of ground effect ships. This is a cooperative project of many companies.
