Abstract
The invention relates to a vacuum discharge valve which is composed of a valve, a transmission and a motor. The valve is formed by a valve body, an impeller, a side cover, a valve shaft, a bearing, screws and permanent magnet materials. A material inlet is arranged at the top of the valve body, and a material outlet is formed at the bottom of the valve body. The impeller is accommodated in the valve body, and is composed of a round port, blades and baffles. Magnetic slots are formed in the blades of the impeller in the upper ends of the upper surfaces of the baffles, and permanent magnet materials are poured in the magnetic slots. The blades of the impeller, the arc ends on the upper surfaces of the baffles and the inner wall of the valve body are sufficiently attached to each other. The impeller and the valve shaft are integrally fixed, the valve shaft is supported by the bearing, and one end of the valve shaft extends out of the valve body to connect the transmission and the motor and start up the motor. The motor drives the valve shaft and the moving impeller to rotate through the transmission, and the impeller rotates to work. Materials are fed in from the material inlet in the valve body through rotating of the impeller and are discharged from the material outlet below the valve body. Permanent magnet materials are adopted to serve as the main body of a sealing unit to attached sealing of the friction surfaces is achieved, sealing and air tightness are good and air leakage during rotating is little. Protruding surfaces arranged on wall surfaces of the material inlet and the material outlet reduce abrasion between the impeller and the valve, so the work energy consumption is reduced and the service life of the valve is prolonged.
