when the fixed inner spiral sheet (21) is used for assisting sundries to deposit, the driven gear hollow shaft (23) is driven by the driving gear (24) to drive the rotating outer spiral sheet (22) to spirally move on the fixed inner spiral sheet (21), so that the sundries fall.
10. A water-saving process for water-saving clean production is characterized in that: by means of the apparatus of claim 5 and/or after the process of claim 9; the water-saving process comprises the following steps of;
SA, firstly, reclaimed water enters a gap reservoir (26) through a water inlet channel water outlet pipe (25), and a swing type filter cylinder (32) swings a station on an opening; then, after the water stored in the intermittent reservoir (26) reaches a set water level, a first sewer pipe (27) is opened, so that the stored water falls into the swing inlet and outlet oblique port (33) from the swing inlet and outlet oblique port (33), falls into a secondary water tank (6) from meshes on the swing filter cartridge (32) for filtering, and washes the meshes through the falling impact of water flow;
SB, when the mesh is blocked, the water leakage speed of the mesh is reduced, so that the water storage capacity in the swing type filter cartridge (32) is larger than a set threshold value, and the gravity center of the swing type filter cartridge (32) moves to an open end from the tail part of the swing type filter cartridge (32) beyond the fixed filter support frame (30), so that the swing type filter cartridge (32) swings downwards to a swing station below the opening;
SC, firstly, when the swing type filter cartridge (32) swings to a swing station below the opening, the swing type filter cartridge magnet block (34) is attracted to the fixed magnetic seat (45); then, the upper pendulum of the filter cartridge tail guide cylinder (37) enters the front cohesion cover (50) from the process lower opening (51); secondly, under the drive of the push rod, the rear connecting seat (52) moves forwards to overcome the spring force, the front holding cover (50) moves along the axis to clean the rear connecting seat (40) on the front top so as to overcome the forward movement of the reset spring (41), and the front cleaning hairbrush (43) cleans the interior of the swing type filter cartridge (32) to enable sundries to be discharged through the sundry storage pipeline (44); after cleaning, resetting by spring force;
SD, after the clearance is accomplished, swing motor (48) swing cover body (47) swing for preceding cohesion cover (50) pushes down clearance back connecting seat (40), thereby make swing filter cartridge magnet piece (34) and fixed magnetic seat (45) separation, the focus of swing cartridge filter (32) is passed through fixed filtration support frame (30) and is removed to afterbody from swing cartridge filter (32) open end, makes swing cartridge filter (32) swing down to the swing station on the opening.
