Description

Technical Field

[0001] The utility model relates to the technical field of material conveying elevators, and more specifically, to a material conveying elevator for powder production. Background Art

[0002] In the process of powder conveying, a material conveying elevator is required. At present, the material conveying elevators for powder production on the market include a rotating shaft, a driving component, and a vertically arranged material conveying cylinder; on one side of the lower end of the material conveying cylinder, there is a feed hopper, on one side of the upper end of the material conveying cylinder, there is a discharge pipe, the upper end of the material conveying cylinder is fixed with an upper end cover, the lower end of the material conveying cylinder is fixed with a lower end cover, and a support frame is fixed on the lower end of the lower end cover. The rotating shaft is arranged inside the material conveying cylinder, the upper end of the rotating shaft passes through the upper end cover and is rotatably connected to the upper end cover, the lower end of the rotating shaft passes through the lower end cover and is rotatably connected to the lower end cover. On the outer wall of the rotating shaft located inside the material conveying cylinder, there are spiral material conveying blades fixed. The driving component is fixed on the support frame, and the rotating shaft is in transmission connection with the driving component; when this material conveying elevator for powder production is working, the rotating shaft and the spiral material conveying blades are driven by the driving component to rotate, and the spiral material conveying blades can lift the powder entering from the feed hopper to the position where the discharge pipe is located and finally discharge it through the discharge pipe. However, in the above process, when the spiral material conveying blades convey the powder, the powder will be in a state of being squeezed and compressed, which easily leads to an increase in the temperature of the powder, so that the powder is prone to adhesion and caking, and even the spiral material conveying blades are easily stuck by the powder. Summary of the Utility Model
