Rotary air-locking discharging device with scraping plate type blades

Abstract

The invention relates to a rotary air-locking discharging device with scraping plate type blades, and belongs to the field of discharging equipment. The rotary air-locking discharging device comprises a main body, a rotary wheel, a fixed shaft, a driving motor and a shaft seat, a feeding port is formed in the upper end of the main body, a discharging port is formed in the lower end of the main body, and a cylindrical cavity is formed in the middle part of the main body, both the feeding port and the discharging port communicate with the cylindrical cavity, one side, located on the cylindrical cavity, of the main body is perpendicularly connected with the shaft seat, the transverse fixed shaft is installed on the shaft seat in the direction deviating from the cylindrical cavity, a rotating wheel is arranged on the outer side, located on the fixing shaft, of the cylindrical cavity in the circumferential direction, one end, deviating from the shaft seat, of the rotating wheel is connected with the driving motor through a driving shaft, the driving motor is fixedly connected with the main body, and the rotating wheel is provided with the plurality of scraping plate type blades. Through the specially designed scraping plate type blade structure, the rotating wheel and the fixed shaft are separated, adhesion resistance is prevented, and the discharging efficiency is high.

Description

technical field [0001] The invention belongs to the field of unloading equipment, in particular to a rotary air-lock unloading device with scraper blades. Background technique [0002] As a special unloading device, star-shaped air lock unloading device is often used in pressure output system or negative pressure output system. The upper feeding port receives the material and stores it in the blade interval on the impeller, and the impeller rotates to bring the material to the lower discharging port, and the material falls from the discharging port by its own weight. While unloading evenly, the upper and lower air pressure is cut off to lock the air. [0003] In the existing star-shaped air-lock discharge device, the usual impeller is composed of an intermediate shaft and several blades, and rotates together as a whole. When unloading viscous materials, the materials adhere to the impeller, and it is difficult to fall from the discharge port by its own weight, and the unlo...
