In appearance, Dongfeng Yufeng uses a large number of straight lines and tamping strips to ensure that the gas is strong, practical and durable. In the interior space, it uses car dashboards, rich storage design, spacious and comfortable, with the largest car in its class. Space; control, the car uses a Renault - Nissan ZD30 engine + modern 6MT gearbox power combination, power efficient energy-saving, control arbitrary; in technology configuration, the car is equipped with automatic cruise, IMMO smart anti-theft, BCM body control system , remote control keys, GPS, reversing images and other technologies to make driving more convenient; in terms of safety, Dongfeng Yufeng is adhering to the European collision design standards, the use of ultra-high strength galvanized steel, equipped with dual airbags, Germany Continental ABS + EBD Four-wheel vented disc brakes allow safety to be accompanied. 
In addition, Dongfeng Yufeng has also stepped up the pace of development of modified vehicles, and cooperated with well-known domestic conversion companies, and actively formed its own modification team to improve the research and development capabilities of modified vehicles and enrich product lines. Today, Dongfeng Yufeng has developed dozens of special models such as ambulances, police vehicles, engineering vehicles, and school buses, which can meet the needs of different industries. Dongfeng Yufeng also persists in practicing the lean production management system, striving for excellence in quality, and creating a caring service in the service so that the user can enjoy the perfect car-car experience.
As China's independent brand of light passengers, Dongfeng Yufeng bears the burden of leading independent brands to achieve breakthroughs, and shoulders the strong social responsibility of leading national brands. The Dongfeng Yufeng debuted at the Global Public Procurement Forum, not only is an important measure to practice the brand and social responsibility, but also shows that Dongfeng Yufeng is striding toward the field of official vehicles and sets a new standard for car use in the industry.
The dewatering process of belt press filter with Belt Filter Press can be divided into four important stages: pre treatment, gravity dehydration, wedge-shaped area prepressure dehydration and pressing dehydration. All new equipment Filter Press automatic filter press, diaphragm filter press, deep Sludge Dewatering press, integrated sewage sludge treatment equipment, on-line precision Filtration system and other environmentally friendly filter products with reasonable price and reliable performance.
brief introduction
belt pressure filter
Structure introduction
The belt press filter is mainly composed of the driving device, the rack, the press roll, the upper filter belt, the lower filter belt, the filter belt tensioning device, the filter belt cleaning device, the discharging device, the gas control system and the electric control system. China has a large number of industrial chains, low production concentration, low level of research and development of high-end products, low manufacturing technology in the belt filter press industry, and the expansion of the import and export trade deficit. The next few years will be the high-speed concussion period of the belt filter press industry. The direct consequence of this high-speed oscillation is the expansion of polarization in the brand camps. There are absolutely not many enterprises that can really survive in the market in the next few years. But this high-speed oscillation of belt filter industry will bring huge opportunities, and the result of turbulence will make the operation of the market more rational. The road of high-end electric home localization is "bumpy". The foundation has become a short board which restricts the development of the belt filter press industry to the high end. In 12th Five-Year, the government will continue to increase the domestically made efforts of the high-end equipment parts of the belt press. The products are also widely used for environmental protection, municipal, mining, electric, chemical, electronic, food and food products. All walks of life, such as pharmaceuticals, textiles and other industries.
belt pressure filter
The structure and working conditions of the main components are briefly introduced below.
1 rack: the belt press filter rack is mainly used to support and fix the press roller system and other components.
2 the press roller system is composed of a roller arranged in diameter from big to small. The sludge is clamped by the upper and lower filter bands, and the pressure gradient is formed under the action of the strain of the filter. The pressure of the sludge in the process of dewatering is increasing, and the water content in the sludge is gradually removed.
3 gravity dewatering device: mainly composed of gravity zone bracket and material trough. After the flocculated material is removed, a large amount of water is removed in the gravity area and its fluidity becomes worse.
4 wedge zone dehydration device: the wedge zone formed by the upper and lower filter belt exerts pressure on the gripped material and prepressure dehydration to meet the requirement for the liquid content and fluidity of the press dehydration section.
5 filter band is the main component of the belt press filter. The separation process of the solid and liquid phase of the sludge is all above and the filter zone is the filter medium. The pressing force is obtained by passing the press roll under the tension force of the upper and lower filter bands.
6 filter adjustment device: from the executive parts: cylinder, adjustment roller signal, anti air pressure, electrical system. Its function is to adjust the deviation of the filter band caused by the uneven tension of the filter belt, the installation error of the roller and the unequal feeding, so as to ensure the continuity and stability of the belt press filter.
7. filter cleaning device: consists of sprinkler, washing water cartridge and cleaning hood. When the filter belt walks, the cleaning device is continuously washed and the pressure water is impacted by the sprinkler. The material remaining on the filter strip is separated from the filter zone under the action of pressure water, making the filter regenerated and preparing for the next dehydration process.
The 8. filter belt tensioning device consists of a tensioning cylinder, a tensioning roll and a synchronous mechanism. Its function is to tighten the filter belt and provide the necessary tension conditions for the production of pressing force of the squeezed dehydration. The adjustment of the tension size can be achieved by adjusting the pressure of the tension cylinder of the pressure system.
9 discharge device: composed of scraper plate, tool carrier, discharge roller, etc., its function is to peel the dehydrated cake and filter belt to achieve the purpose of discharging.
10 transmission device: by motor, reducer, gear transmission mechanism and so on, it is the power source of the belt walking, and can adjust the speed of the reducer to meet the requirements of different speed in the process.
11 air pressure system: the system is mainly composed of power source (gas storage tank, motor, gas pump, etc.), actuating components (cylinder) and air pressure control elements (including pressure relay, pressure flow and direction control valve). Through the air pressure control element, the air pressure, the flow and the direction are controlled, and the pressure and speed of the pneumatic actuator are guaranteed, and the work is done normally according to the predetermined program. It is the power source to complete the tightening and adjusting operation of the filter belt.
