PURPOSE: An automatic filtering equipment is provided which separates solid phase materials from filtrate without stopping filtering regardless of types of the filtrate, and efficiently discharges filtered foreign materials to the outside of the filter. CONSTITUTION: The automatic filtering equipment comprises an automatic filter(1) the upper body of which is openable; a shaft seal pipe(3) on which holes are perforated so that filtrate passes through the holes, and which is fixed in the center of a filter mesh(2) so that the shaft seal pipe(3) penetrates upper and lower parts of the filter mesh(2); a speed reducer (geared motor)(13) that is adhered to the upper part of the shaft seal pipe(3); a mechanical seal(4) adhered between the upper body of the automatic filter(1) and the shaft seal pipe(3) to seal therebetween; a rotary joint(5) adhered to the lower part of the shaft seal pipe(3); an outlet(6) which discharges foreign materials to the outside, to the circular front surface of which a rubber packing is adhered, and at the rectangular rear surface of which a cylinder(11) is installed to move the outlet(6) back and forth; a rubber bellows pipe(12) completely covering the cylinder(11); a spring(9) and a spring fixing unit(10) for adjusting position of the outlet(6); and a control part(17) for cutting off a power source of the speed reducer(13) to stop rotation of the filter mesh(2), supplying a power source to the cylinder(11) to move the cylinder forward so that the outlet is closely adhered to the filter mesh, and supplying a power source to a solenoid valve(8) in rear of a bellows pipe(7) attached to the outlet(6) to open the solenoid valve(8) so that backwashing is performed as foreign materials adhered onto the outer part of the filter mesh(2) are being removed, and filtering process is continuously being performed.
