Equipment for recovering waste rubber fiber

The utility model discloses equipment for recovering a waste rubber fiber. The equipment comprises a fiber separator, a dust remover, a cyclone collector, a vibrating screen and a rubber grinder, wherein the feed opening of the dust remover is communicated with the fiber outlet of the fiber separator; the feed opening of the cyclone collector is communicated with the rubber material outlet of the fiber separator; the discharge opening of the vibrating screen is communicated with the feed opening of the rubber grinder; a mechanical type gravity flap valve is communicated between the cyclone collector and the vibrating screen, and the mechanical type gravity flap valve comprises a valve body; the valve body is internally provided with two overturning plates which are arranged up and down, the overturning plates are arranged on a rotating shaft which is horizontally and transversely arranged in the valve body, and overturning torques are formed between the rotating shaft and the center of gravity of the overturning plates; and one end of the rotating shaft protrudes out of the valve body to be connected with a balancing weight. According to the equipment, an air lock is substituted by using the mechanical type gravity flap valve, and a blanking process is unnecessary to be controlled by an electric appliance, so that no mechanical electric fault is generated, no maintenance is needed, and the production is not influenced.
