The utility model relates to the technical field of
polypropylene particle cleaning, and discloses a
raw material cleaning device for
flame-retardant
polypropylene sheet production, which comprises a box body, and a cleaning device is arranged on the box body. According to the
raw material cleaning device for
flame-retardant
polypropylene sheet production, the mounting cylinder, the filter screen, the rotating seat, the positioning bolt, the first motor, a sliding rod, a second motor, a rotating rod, a gear, a sleeve, a gear ring and a mounting plate are arranged, the first motor is started to enable the mounting plate and the mounting cylinder to move downwards and sink into the water surface, the second motor is started, and the rotating rod is used for driving the rotating seat and the mounting cylinder to rotate; the polypropylene particles in the mounting cylinder are dewatered, so that water is prevented from dripping on the outer side of the box body, and meanwhile, subsequent
drying of the polypropylene particles is facilitated; and by arranging the
square rod, the cover plate, the screw rod and the U-shaped plate, the cover plate is positioned by utilizing the U-shaped plate, so that the mounting cylinder is conveniently blocked, and soaking, cleaning and water throwing of the polypropylene particles are facilitated.
