Description

Technical Field

[0001] The utility model relates to the technical field of powder material conveying, in particular to a powder material spiral conveying device. Background Art

[0002] Screw conveyor is a commonly used powder conveying equipment. It is widely used in various production fields due to its large conveying capacity, good sealing performance and high efficiency. Its principle is to use the motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

[0003] The patent document with the existing application number CN201822192694.X discloses a powder screw conveyor, including a shell, a feed port and a discharge port are respectively arranged at both ends of the shell, a rotating shaft, a driving motor and a spiral blade are arranged in the shell, the pitch of the spiral blade is arranged in an increasing manner, a plurality of closed doors are rotatably connected to the shell, an arc strip is fixed on the closed door, and a clamping rod and a driving assembly are arranged on the shell. The driving motor can drive the rotating shaft to rotate relative to the shell, and the spiral blade conveys the powder. Because the pitch of the spiral blade is arranged in an increasing manner, the conveying amount of the spiral blade at the feed port is less than the conveying amount at the discharge port, which effectively reduces the occurrence of clogging of the screw conveyor, and when the closed door is opened, it is convenient to effectively clear the clogged powder.
