The invention discloses a fine sand screening device of a vacuum fine sand machine and a sieving method thereof. The fine sand screening device comprises a main support frame, a circular screening structure, an all-metal shell, a first vibrating screen mesh and a particle size sensor, wherein the circular screening structure is arranged above the main support frame; a circulating pipeline is arranged above the circular screening structure; a first electromagnetic valve is arranged below the circulating pipeline; a second electromagnetic valve is arranged at one side of the first electromagnetic valve; a third electromagnetic valve is arranged at one side of the second electromagnetic valve; a circular driving motor is arranged below the third electromagnetic valve; a fine sand outflowing pipe is arranged at one side of the circular screening structure; and the all-metal shell is arranged above the fine sand outflowing pipe. The fine sand screening device has the beneficial effects that1. when gravels are screened, the gravels can be circularly screened, the screening efficiency is high, and the screening effect is good; 2. the particle size of the screened gravels can be sensed, and the screening effect is ensured; and 3. the gravels are screened in a full mechanical manner, and lots of manpower resources are saved.
Description
technical field [0001] The invention relates to the field of sand and gravel screening equipment, and the invention relates to a fine sand screening device of a vacuum spinning machine and a screening method thereof. Background technique [0002] Vacuum sand suction machine is a kind of dust removal equipment used for pneumatic pipeline transportation of bulk granular materials. It is mainly composed of a shakeout tank equipped with a sand suction pipe and a suction pipe, a filter element reverse blowing cyclone dust collector and a water ring vacuum pump that are fixedly installed in a square frame. The suction pipe of the water ring vacuum pump is connected to the upper air chamber of the dust collector, and the suction pipe of the shakeout tank is connected to the air inlet of the cyclone air duct of the dust collector. [0003] When the existing fine sand screening device recycles the gravel, a large amount of labor is required to maintain the equipment, and the labor c...
