Rapid screening device for small-particle quartz sand

The utility model discloses a small-particle quartz sand rapid screening device which comprises a shell, a feeding port is formed in the upper portion of the shell in a penetrating mode, a first filter screen is fixedly connected to the interior of the shell, a vibration motor is fixedly connected to the lower portion of the first filter screen, and a collecting box is fixedly connected to one side of the shell. One end of the first filter screen penetrates through the shell and corresponds to the collecting box, a conveying pipe is arranged above the collecting box in a penetrating mode, the other end of the conveying pipe is arranged in the feeding port, and a suction pump is arranged in the middle of the conveying pipe; by arranging a first filter screen and a vibration motor, small-particle quartz sand entering the shell can be subjected to vibration screening, and by arranging a collecting box, a suction pump and a conveying pipe, the small-particle quartz sand which is not completely screened can be fed
