    Patent for invention

    Pneumatic conveying system

      The company has organized wind tunnel experts and research teams to invent a wind powered rotary feeder after years of research. The wind powered rotary feeder has a compact structure, occupies a small area, and is easy to arrange in the process. And the conveying distance is long, the conveying height is high, the pipeline is fully sealed, and there is no emission or pollution. It uses a low-pressure air source instead of compressed air to achieve pipeline transportation. The material is quickly transported in a spiral state through the pipeline to the designated locations. The conveying horizontal distance can reach 0~500m, the height can reach 0~70 meters, and the conveying capacity is 0~480T/H. Each conveying can consume only about 0.5~1.7KW/H, which saves a considerable amount of electricity consumption. Moreover, traditional pneumatic transportation currently has low capacity, high investment, high energy consumption, and high requirements for pipelines. The layout of air ramps and elevator conveying equipment is limited, maintenance costs are high, and air pollution is severe.

    Main purpose

    The company has organized wind tunnel experts and research teams to invent a wind powered rotary feeder after years of research.

Each conveying can consume only about 0.5~1.7KW/H, which saves a considerable amount of electricity consumption. Moreover, traditional pneumatic transportation currently has low capacity, high investment, high energy consumption, and high requirements for pipelines. The layout of air ramps and elevator conveying equipment is limited, maintenance costs are high, and air pollution is severe.

    Structure and characteristics

    Various industries such as electricity, building materials, ports, chemicals, metallurgy, and grain storage.

    Suitable for conveying materials

    Fine coal powder, fly ash, mineral powder, lime powder, cement and other dry powders, as well as objects with particles ≤ 25mm such as salt, wheat, grains, beans, corn, etc.

    Product advantages

    Model Traditional pneumatic transportation High performance air supply system
    Conveying height <40m The current case is 65m (Yunyang, Chongqing)
    Temperature and air pressure inside the conveying pipe High (temperature>60, air pressure>700Kpa) Low
    Requirements for conveying pipelines Special steel seamless pipe, replacement every 1-2 years 10mm thick ordinary spiral plate, replaced every 5-6 years
    Blockage phenomenon Frequent occurrence and large amount of loose pipeline engineering No occurrence, the pipeline can be buried underground
    Energy consumption Tall Low (1/6 of traditional pneumatic transportation energy consumption)
    Operating cost Tall Low (1/5 of the operating cost of traditional pneumatic transportation)


    Negative pressure suction+positive pressure feeding system

    Advantage

    ♦  Easy installation
    The transformation of the enterprise from design to installation will not affect the normal production of the enterprise.
    It is very safe to transport materials under low pressure in pipelines
    ♦  environment protection
    Fully sealed logistics transportation
    ♦  Efficient
    Large conveying tonnage.
    Not affected by changes in weather conditions.
    Compared to conventional compressed air delivery, this equipment will not cause any blockage.
    ♦  Flexible arrangement
    The entire transportation layout is made of ordinary material pipelines
    Arranging pipelines can build multiple points and warehouses.
    The pipeline can turn up, down, left, and right from the starting point to the target library.
    ♦  Low maintenance cost
    The material is transported in a rotating mode within the pipeline, resulting in minimal wear on the pipeline
    Transporting materials without consumption
    ♦  energy conservation
    Compared to the electricity consumption of commonly used compressed air conveying equipment, this device consumes one-third of its electricity
    (Actual operating power consumption ÷ Total amount of materials transported per hour) x Electricity price=Operating cost Electricity fee

    Air supply system


    Warehouse to warehouse air delivery system

    Positive pressure+negative pressure air supply system

    Case study of conveying system

      Chongqing Yunyang Hongqi Cement Factory Pier
    This project is used to coordinate with the spiral unloader to transport cement from the ship to the designated warehouse.
    Geographical situation on site: Annual drop in water level: about 32 meters
    Equipment installed capacity: Roots blower power: 280KW
    Conveying distance: horizontal distance of 242 meters+vertical height of 65 meters
    Conveying capacity: 90-100t/h
    Operation date: November 2015
    When the area is in the dry season (with the lowest water level in the river), currently only our equipment can transport it.
    Therefore, during this period, the user raised the cement price by 20 yuan/ton.
