Air conveying chute for cement production line

The utility model discloses an air conveying chute for a cement production line. The air conveying chute for the cement production line comprises a chute body, wherein a feeding hole and a discharging hole are formed in the chute body; a breathable canvas layer is arranged at the interior of the chute body; an air chamber is formed in the lower part of the breathable canvas layer; an air inlet pipe arranged on the air chamber is used for supplying air for the air chamber; an air jetting hole is used for jetting air and driving powder on the breathable canvas layer to carry out fluidization transportation; a buffering layer used for buffering impact force during discharging the powder is arranged on the breathable canvas layer corresponding to the feeding hole of the chute body; the buffering layer comprises two buffering plates which are parallel up and down; through holes are formed in each buffering plate; circle centers of the through holes in the upper and lower buffering plates are staggered; the diameter of the through holes in the lower-layer buffering layer is smaller than the diameter of the through holes in the upper-layer buffering plate. According to the air conveying chute for the cement production line, the two layers of buffering plates are arranged in the feeding hole and are used for fully dispersing and buffering the materials; the excessive impact abrasion to the canvas layer by the materials is avoided; the service life of the canvas layer is greatly prolonged; the fault rate of a system is reduced.
