Technical Field

[0001] The utility model relates to the technical field of suction and pressure-feeding vehicles, in particular to a suction and pressure-feeding semi-trailer. Background Art

[0002] Suction and pressure conveying vehicles are widely used in the in-plant and out-of-plant transportation of various types of dust ash (sintering, coking, smelting desiliconization, desulfurization, dephosphorization agent, blast furnace, converter dust ash, lime powder, mill scale, coke powder, smelting desiliconization agent and other dust materials) generated in the production of various industries (ironmaking, steelmaking, metallurgy, energy and chemical industry, energy and electricity, glass factories, cement factories). The suction and pressure conveying semi-trailer is modified based on the suction and pressure conveying vehicle. The suction and pressure conveying semi-trailer has all the operating functions of the suction and pressure conveying vehicle. The suction and pressure conveying semi-trailer is suitable for the operation and transportation of dust ash on hardened and flat roads. During operation, the vehicle adopts negative pressure (positive pressure can be used when the silo conditions are met) loading and positive pressure discharging (lifting and opening the rear cover for dumping in an emergency); the filtered dust-laden air meets the national environmental protection emission standards.
