The novel horizontal air separator according to claim 1 is characterized in that: The speed increasing nozzle (43) is a flat nozzle with a rectangular cavity cross section, the cavity cross section gradually decreases from bottom to top, and the inclination direction of the flat nozzle (43) is arranged tangentially to the roller of the discharge head (20); The lower connecting end (421) and the upper connecting end (422) are connected through an arc bent pipe, and the lower connecting end (421) is arranged obliquely outside the feeding head of the second belt conveyor (3); the upper connecting end (422) is arranged parallel to the feeding head of the second belt conveyor (3) and parallel to the discharging head (20) of the first belt conveyor (2).

7. The novel horizontal air separator according to claim 1 is characterized in that: A CCD high-definition acquisition camera (15) electrically connected to the control module is also provided at the lower left end of the horizontal sorting chamber (10). The CCD high-definition acquisition camera (15) captures the quantity and frequency of thin film materials in the bulk material. When the quantity and frequency of thin film materials are abnormal, the control module controls the speed of the fan (41) to increase, while reducing the feeding speed of the first belt conveyor (2).

8. The novel horizontal air separator according to claim 1 is characterized in that: A blockage relieving assembly (9) is provided at the connection point between the first air duct (51) and the drainage duct (14); a blockage relieving plate (92) of the blockage relieving assembly (9) has the same profile as the upper wall of the first air duct (51); a telescopic rod of a blockage relieving cylinder (91) passes through the first air duct (51) and is connected to the blockage relieving plate (92); the blockage relieving cylinder (91) is periodically extended and retracted to cause the material at the bend to fall.

9. The novel horizontal air separator according to claim 8 is characterized in that: The blockage-clearing cylinder (91) is fixed on a cylinder seat (90), and the cylinder seat (90) is connected to the first air duct (51) or the horizontal sorting chamber (10). Two vertical guide rods (94) are provided between the upper top plate (901) of the cylinder seat (90) and the blockage-clearing plate (92). The blockage-clearing plate (92) is annular and has cutting edges on the inner hole wall and the outer end wall of the lower end. Alternatively, a rubber elastic layer (93) is provided on the upper end of the blockage relieving plate (92).

10. The novel horizontal air separator according to claim 1 is characterized in that: The right side of the lower port of the horizontal sorting chamber (10) is used to remove materials upward to form a rectangular feed port (102), and the left side of the lower port forms a discharge port (103); the first belt conveyor (2) is located below the feed port (102) and extends into the guide screening chamber (100); the second belt conveyor (3) is located below the discharge port (103); the horizontal sorting chamber (10), the first belt conveyor (2), and the second belt conveyor (3) are inclined at the same angle; Or the clean discharge section (7) is a high chimney; Or the first conveyor belt (21) and the second conveyor belt (31) are skirt belts or the conveyor frames on both sides of the conveyor belts are provided with limit baffles; Or the drainage tube (14) is a rectangular tube.
