Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Fig. 1-3, a kind of oil well sewage filtration device for oil field development, comprises frame 1, provides support and installation space for other parts in the device, the top of described frame 1 is provided with filter box 2, in filter box 2 is rotatably connected with a filter cartridge 3 arranged horizontally and extending to the outside of the filter box 2 at both ends. One end of the filter cartridge 3 is open to discharge sludge. The other end of the filter cartridge 3 is provided with The port 4 is provided on the frame 1 with a mud discharge bucket 5 adapted to the open end of the filter cartridge 3, and the frame 1 is provided with a water inlet pipe 6 that moves through the port 4 along the horizontal direction. A number of filter holes 7 located in the filter box 2 are evenly distributed on the cylinder 3, and a drain pipe 8 is connected to the bottom of the filter box 2; a rotating drive mechanism 9 connected with the filter cylinder 3 is provided on the frame 1, The inner cavity of the filter cartridge 3 is in the shape of a circular platform, so that the inner bottom surface of the filter cartridge 3 between the water inlet pipe 6 and the mud discharge hopper 5 is always kept in an inclined state, so that the sewage entering the filter cartridge 3 through the water inlet pipe 6 can flow to the mud discharge hopper. 5 direction, and then filter through the filter hole 7; During the sludge discharge process, the rotary drive mechanism 9 drives the filter cartridge 3 to rotate, increasing the usable filtration area, and at the same time, through the slight vibration generated during the operation of the device, the sludge is not easy to adhere to the inner surface of the filter cartridge 3, and the sewage Mud can smoothly flow to the mud discharge bucket 5 along the inclined surface, which is convenient for sludge to be discharged.

Wherein, the upper end of the filter box 2 is open, and the upper end of the filter box 2 is connected with a case cover 10 by a flange. The inner bottom of the tank is provided with a cleaning pipe 11 that is connected to the external water supply system, and a plurality of nozzles 12 are evenly distributed on the bottom of the cleaning pipe 11. When the filter holes 7 need to be cleaned, the rotary drive mechanism 9 drives the filter cartridge 3 to rotate, and the nozzle 12 sprays water to the filter cartridge 3 at the same time, so that each filter hole 7 can be cleaned to ensure subsequent filtering effect. Further, the filter hole 7 is arranged vertically and its outer end is trumpet-shaped, which facilitates the spray water to enter the filter hole 7 and flush out the blockage in the filter hole 7 .

Preferably, the port 4 is provided with a sealing ring 13 compatible with the outer ring of the water inlet pipe 6, which can seal the junction and prevent sewage from entering the filter cartridge 3, passing through the gap between the water inlet pipe 6 and the port 4. Gap overflows.
