Sand washing device for filtration system

Abstract

The invention discloses a sand washing device for a filtration system. The sand washing device comprises a device body, a shell, a stirring shaft, a driven gear, a motor, a fan, a bulge and a sand washer main body. The shell is arranged at one end of the device body. The sand washing device is scientific and reasonable in structure, by arranging the motor and the fan, the motor is started to drivea rotating shaft to rotate, the stirring shaft drives stirring blades to stir sand, meanwhile, the fan blows air into an aerator pipe, the aerator pipe outwards blows the air, thus dirt in the sand is upwards floated along with stirring, the dirt or the dirty sand enters the sand washer main body and is spirally stirred through an internal spiral blade when passing through a sand washing channel,and the sand is mutually rubbed to remove the dirt; and compared with traditional modes that the dirt is removed only through friction between the sand and meanwhile the sand washing channel is proneto being blocked, the stirring shaft rotates to enable the spiral blade to rotate to increase friction between the sand, and the sand is effectively prevented from blocking the sand washing channel while the dirt is removed.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a sand washing device for a filtering system. Background technique [0002] The sand washer is an indispensable supporting device on the active sand filter. Its function is to automatically and continuously clean the filtered sea sand. The sand passes through the sand washing channel inside the sand washer to separate and purify the suspended solids from the sand and recover The filter function of the sand, but in the prior art, the sand washing channel only removes dirt through the friction between the sands. If the sand washing channel is too large, the cleaning will not be complete. If the sand washing channel is small, it is easy to block the sand washing channel The phenomenon. Contents of the invention [0003] The object of the present invention is to provide a sand washing device for a filter system to solve the problems raised in the above-mentioned backgrou...
