Wastewater treatment device convenient to use

The invention discloses a wastewater treatment device convenient to use. The device comprises a housing, wherein the lower surface of the housing is fixedly connected to the top ends of four first electric pushing rods, and the four first electric pushing rods are correspondingly positioned at four corners of the lower surface of the housing; pulleys are fixedly connected to the bottom ends of thefirst electric pushing rods; the lower surface of the housing is fixedly connected to the top end of a first rotating shaft which is positioned in the center of the lower surface of the housing. According to the device, a motor, a driving wheel, a driven wheel, a belt, a second bearing, a second rotating shaft, a turntable, a third bearing, a third rotating shaft and a pulling rope are arranged;when the motor runs, the second rotating shaft can be driven to rotate through the driving wheel, the driven wheel and the belt, and the turntable is driven to rotate through the second rotating shaft, and moreover, the tension force of a sieving plate is applied to the third bearing all the time, so that sieving plate can move up and down in one circle while an output shaft of the motor rotates in one circle, and as a result, the filtering effect is improved.
