Zusammenfassung: | The utility model relates to a high-pressure pneumatic conveying technology, in particular to a pneumatic material conveying device which comprises a plurality of sections of conveying grooves in a connecting mode. Each section of conveying groove comprises an upper half groove and a lower half groove. Each lower half groove comprises a bottom side and two side walls. Each side wall of each lower half groove comprises a pneumatic transmission plate and a pressing strip. The pneumatic transmission plates are main bodies of the side walls. The pressing strips are arranged on the inner sides and the outer sides of the pneumatic transmission plates. The pressing strips and the pneumatic transmission plates are fastened through bolts. Pressing sealing is achieved through the pressing strips. According to the pneumatic material conveying device, the pressing strips and the pneumatic transmission plates are matched with each other, pneumatic material conveying device sections are connected, and sealing is achieved. |
