Silica sol product purification device

The utility model relates to the technical field of silica sol production, and provides a silica sol product purification device which comprises a box body, a spiral pipe and a guide pipe which are arranged on the inner side of the box body, and a conveying component connected with the spiral pipe and the guide pipe, the pump body is driven by the motor to operate, silica sol liquid is sucked into the box body through the feeding pipe and is discharged outwards through the discharging pipe after sequentially passing through the spiral pipe, the disc shell and the guide pipe, solid particles in the silica sol liquid are intercepted through the filter screen in the discharging opening in the disc shell, and the solid particles in the silica sol liquid are discharged through the discharging pipe under synchronous driving of the motor. Silica sol liquid passing through the disc shell can be mixed and stirred through the rotating shaft rod and the first stirring plate and the second stirring plate on the periphery
