The invention discloses a coaxial pneumatic conveying ejector comprising a pump block, a material suction passage, a material ejection pipeline, and an ejection gas pipeline. The material suction passage and the material ejection pipeline are formed in the pump block. The material suction passage is communicated with the material ejection pipeline. The ejection gas pipeline is disposed in the material suction passage through a connector. The connector is provided with an inner suction hole communicated with the ejection gas pipeline. One end of the ejection gas pipeline is closed. The ejection gas pipeline and the material suction passage are coaxial. The ejection gas pipeline is disposed in the material suction passage; the ejection gas pipeline and the material suction passage are coaxial; accordingly, material suction resistance is reduced obviously, and the efficiency of ejection conveying is improved. In addition, the material suction passage is symmetrically and evenly arranged, so that the material can be conveyed more evenly.
Description
technical field [0001] The invention relates to a coaxial pneumatic conveying ejector, which belongs to the field of pneumatic conveying ejectors and vacuum ejectors, and is used for conveying single-phase flow, two-phase flow, disguised-phase flow or generating vacuum by means of ejection technology. Background technique [0002] Pneumatic conveying injector is the power part of the loose material conveying system. It uses negative pressure to inhale the loose material, and then mixes the gas and solid inside the material injection pipeline, and performs energy exchange, mixing, gas-solid concentration adjustment and other steps, and finally will Loose materials are transported to designated locations. [0003] like Figure 7 As shown, the common structure of the pneumatic conveying injector in the field of material conveying is generally that the material suction channel 2' and the material injection pipeline 3' form an angle of 90°, and the injection gas channel 4' is coa...
