Referring to fig. 2, as an embodiment, an upper liquid level gauge 17 and a lower liquid level gauge 18 both located above the filter screen 11 are provided in the filter cartridge 1; when the liquid level in the filter cartridge 1 reaches the position of the upper liquid level meter 17, stopping introducing the sewage, and starting the operation; when the liquid level height drops to the position of the lower liquid level meter 18, the sewage is introduced again.
When the time period for the sewage level to descend from the upper level gauge 17 to the lower level gauge 18 exceeds a preset value, for example, more than 2 hours, the filter screen 11 is cleaned.
Referring to fig. 3, at least three support plates 15 are uniformly and annularly arranged on the outer wall of the filter cartridge 1, and lifting lugs 16 are fixedly arranged on the support plates 15; a rope winding rod 21 is arranged right above the filter cartridge 1, and the rope winding rod 21 is in transmission connection with a rope winding motor 22; straight pull ropes 14 are wound on the rod body of the rope winding rod 21, the straight pull ropes 14 are also connected with inclined pull ropes 13 with the same number as that of the lifting lugs 16, and each inclined pull rope 13 is respectively tied and connected with one lifting lug 16;
the rope winding rod 21 and the rope winding motor 22 are installed on the rope winding rod bracket 23.
The speed of the filter cartridge 1 is controlled by controlling the rotation speed of the rope winding motor 22, so that the optimal negative suction filtering effect is achieved.
Preferably, a shock-absorbing pad 24 is arranged below each supporting plate 15; the cushion 24 is preferably a rubber pad.
In summary, the utility model provides a gravity separation type sewage filtering device, which is characterized in that a conical cover is arranged at the bottom of a filtering cylinder; when the filter screen causes sewage to store up in the filter cartridge because of the jam of great large tracts of land appearing, certain height of cartridge filter integral lifting, the liquid that exceeds in the toper cover slowly descends under the action of gravity to produce the burden and inhale the filter effect to the filter screen, make the sewage that stores up fast through the filter screen. The utility model discloses simple structure, under the unchangeable condition of filter screen clearance frequency, ensure the filtration efficiency at the filter screen.
