Description

Technical Field

[0001] The utility model relates to the field of powder material conveying equipment, in particular to a large-angle inclined chute rotating drum structure. Background Art

[0002] Air conveying chute is a commonly used powder conveying equipment in the building materials manufacturing industry. It is suitable for conveying cement and other easy-to-fluidize powder materials. Its specific working principle is to use a certain air pressure to inflate the air box of the chute, fluidize the powder material in the chute through the air permeable layer, and convey it forward along a certain slope. It has the characteristics of strong conveying capacity, no dust loss, and long conveying distance. It is widely used because of its advantages such as no transmission parts in the main body of the machine, convenient sealing operation and management, light weight, low power consumption, large conveying capacity, and easy change of conveying direction.

[0003] At present, the inclination angle of powder chutes is mostly 6 degrees, and the angle of the rotating drum (bend chute) is mostly designed according to process requirements. With the increasing use of more types of materials (granular and powdery mixtures), since the fluidity of these materials is not as good as that of powders, a chute with a larger inclination angle is required to complete the conveying work.

[0004] However, the existing chute transmission device cannot observe internal abnormalities in time during the transmission process, which seriously affects the transmission work; and as the angle of the chute increases, the defects of the existing drum structure become more and more obvious, that is, the height difference between the feed port and the discharge port increases, and a thicker dead material area is formed for the conveyed material, resulting in poor material transportation; during long-term use, the air permeable layer is damaged and needs to be replaced, and the replacement process is complicated and difficult, which seriously affects the work production efficiency. Summary of the invention

[0005] In view of this, the utility model provides a large-angle inclined trough drum structure, which has the characteristics of easy observation, good transmission effect and high transmission efficiency.

[0008] The air-permeable conveying mechanism includes an assembly frame installed on the inner wall of the cylinder at the lower side of the feed port, a rolled air-permeable layer installed on the assembly frame, a guide limit block provided at the upper end of the assembly frame for supporting and guiding the air-permeable layer, and a fixing block provided on the outer wall of the cylinder at the lower side of the discharge port for pressing the air-permeable layer.

[0009] As a further improvement of the above technical solution, the feed port is provided with a dust cover which can be rotated upward to open.

[0010] Preferably, both sides of the air-permeable layer are sealed and installed by means of sealing strips.

[0011] As a further improvement of the above technical solution, the bottom of the cylinder is provided with a pulley support for supporting and moving the entire device.
