Quartz sand filter adopting water-saving backflushing technology

The utility model belongs to the technical field of quartz sand filters, and discloses a quartz sand filter adopting a water-saving backflushing technology, the quartz sand filter comprises a shell and quartz sand, the quartz sand is arranged in an inner cavity of the shell, a top shell is fixedly connected to the top surface of the shell, and a water inlet pipe and a water outlet pipe are fixedly connected to the left side wall of the top shell; and the top surface of the water inlet pipe is fixedly connected with a connecting pipe. By arranging the motor, the vertical pipe and the transverse pipe, when the device is subjected to backwashing operation, the motor is started through an external power supply, the motor drives the vertical pipe to rotate, and the vertical pipe drives the transverse pipe on the side wall of the vertical pipe to stir quartz sand in the inner cavity of the shell, so that the quartz sand can be loosened, and a backwashing water source can conveniently pass through; therefore, intern
