The filter device comprises a cylindrical container which is obliquely arranged on a frame and can rotate around a horizontal rotating shaft, a water inlet is arranged at the top of the cylinder, a water outlet is arranged at the bottom of the cylinder, a filter plate is arranged on the axial center plane (axial tangent plane) of the cylinder, and the filter plate divides the space in the cylinder into a water inlet cavity positioned above the filter plate and a water outlet cavity positioned below the filter plate. When the filter is in actual use, raw water to be filtered enters the water inlet cavity at the upper part of the cylinder from the water inlet, primary filtered water filtered by the filter plate enters the water outlet cavity and flows out from the water outlet at the bottom of the cylinder; most of the sundries which can not pass through the filter plate fall down along the inclined plane of the filter plate, leave the cylinder through the sundry outlet and are discharged into a sundry pool for further treatment; a small amount of foreign materials may be accumulated on the upper surface of the filter plate to affect the filtering work. After working for a certain time interval, the cylinder is turned over for 180 degrees, namely, the filter plate is turned over, so that sundries originally accumulated on the upper surface of the filter plate can be backflushed and fall into the water outlet cavity, and the filter plate is cleaned equivalently. The cylinder is repeatedly inverted at certain time intervals to turn over the filter plate, so that the problem that the filter screen needs to be cleaned frequently and manpower and material resources are wasted in the prior art can be solved.
Preferably, the water inlet is arranged at the upper edge of the upper end surface of the cylinder, the opening of the water inlet is vertically upward, the water outlet is arranged at the lower edge of the lower end surface of the cylinder, the opening of the water outlet is vertically downward, and the water inlet and the water outlet are in a central symmetry structure.
