the drive assembly includes: the driving gear is arranged at the bottom of the stirring shaft, and the driven gear is in transmission connection with the driving gear through a transmission belt; the scraping plate is fixedly arranged on the transmission belt;
the stirring shaft is provided with a moving block which drives the driving gear to ascend or descend when the forward and reverse rotation motor rotates; a limiting ring for limiting the moving distance of the moving block is fixedly arranged on the stirring shaft; and when the moving block moves to the stroke end point, the moving block is clamped with the limiting ring.
2. A sewage filtering and purifying apparatus as claimed in claim 1, wherein said collecting plate comprises: a first plate body for collecting impurities cleaned by the cleaning component and a second plate body for sealing the collecting tank; the first plate body and the second plate body are arc-shaped plates.
3. The sewage filtering and purifying device according to claim 1, wherein a sewage outlet is formed in the bottom of the sedimentation cavity, and a touch switch is arranged on the sewage outlet and is electrically connected with the control unit; the scraping plate is an inclined plate and is matched with the sewage outlet; and when the scraping plate moves to the stroke end point, touching the touch switch.
4. A sewage filtering and purifying apparatus according to any one of claims 1 to 3, wherein the control unit calculates the discharge amount of the flocculant according to the discharge amount of sewage, and the control unit controls the forward and reverse rotation motor to rotate during the discharge of the flocculant so as to drive the stirring assembly to stir; when the turbidity detected by the turbidity meter is lower than a threshold value, the control unit controls the stirring assembly to stop stirring; after the sedimentation is finished, the control unit controls the forward and reverse rotation motor to rotate reversely so as to control the cleaning assembly to clean the filter screen and control the cleaning assembly to clean flocculates deposited in the sedimentation cavity.
5. The sewage filtering and purifying apparatus as claimed in claim 4, wherein assuming that the discharge amount of the flocculant is f and assuming that the discharge amount of the sewage is w,: f=k (aw+b), where a depends on the type of flocculant, b is a constant factor, k is an empirical parameter, and is set artificially according to the actual situation.
