Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-3, an oil well sewage filtering device for oil field development comprises a frame 1 for providing a supporting and mounting space for other components in the device, wherein a filter tank 2 is arranged at the top of the frame 1, a filter cylinder 3 which is arranged along the horizontal direction and has two ends extending out of the filter tank 2 is rotatably connected in the filter tank 2, one end of the filter cylinder 3 is arranged with an opening for discharging sludge, the other end of the filter cylinder 3 is provided with a through opening 4, a sludge discharge hopper 5 which is adapted to the open end of the filter cylinder 3 is arranged on the frame 1, a water inlet pipe 6 which movably penetrates through the through opening 4 along the horizontal direction is arranged on the frame 1, a plurality of filter holes 7 which are arranged in the filter tank 2 are uniformly distributed on the filter cylinder 3, and a drain pipe 8 is connected to the bottom of the filter tank 2 in a conducting manner; a rotary driving mechanism 9 linked with the filter cylinder 3 is arranged on the frame 1, the inner cavity of the filter cylinder 3 is in a round table shape, so that the inner bottom surface of the filter cylinder 3 between the water inlet pipe 6 and the sludge discharge hopper 5 is always kept in an inclined state, and sewage entering the filter cylinder 3 through the water inlet pipe 6 can flow towards the sludge discharge hopper 5 and is filtered through the filtering holes 7; the filtered sewage is discharged through a drain pipe 8, and the filtered sludge is discharged through a sludge discharge hopper 5.
