    ZY Air Supported Belt Conveyor

      

    I. Description

    In recent years, the technology and equipment of modern logistics, especially the modernized port construction, have been developing rapidly.

     

     

     

    The 21st century will stride into a new age where those industries, such as port, mine, coal, electric powder,etc. Will be energy-efficient, environment-friendly, low-carbon but efficient. Therefore, the large-capacity air supported belt conveyor will be urgently needed. A technology revolution must be conducted in the conveying system of electric powder and coal industries when they are faced with the new situation of energy conservation, emission reduction and green environment protection. It is imperative that the air supported belt conveyor will gradually replace the stationary belt conveyor which has heavy pollution.

     

     

     

    After the broad and through market research, it is found that all those industries, such as coal wharf, ore terminal, and 10minniomKW large-scale thermal powder plant, expect the green environment-friendly air supported belt conveyor with conveying capacity being 3600-4000t/h. 

     

     

     

    To this end, we successfully developing the energy-efficient, environment-friendly and large-capacity air supported belt conveyor (the third-generation air supported belt conveyor) with more than two years. The stringent performance test shows that each economic and technical index of the air supported belt conveyor reaches the international advanced level, and that when the conveying capacity is 4000t/h and frictional resistance loss index is 0.4-0.8Pa/M, it can still be directly started will full load. The index of starting under full load and that of the loss due to frictional resistance take the world leading level, which indicates the technical level of the air supported belt conveyor of our country has been the best among the counterparts in the world.

    III、Main Technical Index

    1. Favorable running effect:

    Without drifting, blowing powder, grazing, and raising dust, the conveyor of this type is stable and firm, safe and reliable, which makes environment-friendly, energy-efficient, low-carbon and civilized delivery come true.

     

    2. Large overloading capacity: 

    The overloading coefficient of the large-scale air supported belt conveyor can reach 1.2 to 1.25.

     

    3. Large area of material stocking friction: 

    The area of material stocking friction and conveyor capacity of B1800, B2000 large-scale air supported belt conveyor are increased by 15% to 20%,which can fully meet the technical requirements of the large-scale air supported belt conveyor running under any operating mode.

     

    4. Remarkable effect of energy consumption: 

    The energy of horizontal transmission can be saved by 15% to 25%, and that of transmission up the slope can be saved by 5% to 15%.

     

    5. Low operating cost:

    The maintenance expense is saved by 75%, the working life of the belt is lengthened by four times, and comprehensive benefits are improved by 30%.

     

    6. Good performance in starting with heavy load:

    Starting with heavy load, whose powder is only 1.3 to 1.4 times of the running one,can be easily and directly conducted.

     

    7. Innovative material clearing plant: 

    The material clearing plant has been improved to increase the sweeping effect and to prevent the belt bringing crushing materials into the air cushion, solving the material clamping problem.

     

    8. Intelligent control:

    The electric control system of the conveyor, which is developed by our company, is a system controlled and monitored by the computer where automation in conveying process is realized. The control system adopts the way of distributed control, that is, a combination of concentrated control and centralized control. So it can control and test the whole set of the system, including conveyor, precipitator, bucket elevator, feeder as well as many devices and signals consisting of deviating, slipping, blocking, tensioning, tearing, fill level, pressure, temperature of dynamo, bearing, hydraulic coupler, etc. The control system improves the working environment of operating personnel, reduces the labor intensity, enhances the productivity, and improves the safe reliability of equipment operation at the same time.
