Detailed Description
Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
The utility model provides a downhole self-cleaning filtering station, which comprises a first coarse filter 1, a second coarse filter 2 and a precise filter 3, and is characterized in that: the first coarse filter 1, the second coarse filter 2 and the fine filter 3 are all fixed on the underframe 4, the first coarse filter 1 and the second coarse filter 2 are all connected with the fine filter 3, drain outlets are formed in the first coarse filter 1, the second coarse filter 2 and the fine filter 3 and are connected through a drain collecting pipe 5, and a pressure reducing device 6 is arranged at one end of a water inlet of the first coarse filter 1 and one end of a water inlet of the second coarse filter 2.
The chassis 4 is provided with a PLC control box 7.
The pressure reducing device 6 in the utility model is a water inlet pressure reducing valve.
In the utility model, water inlets of a first coarse filter 1 and a second coarse filter 2 are provided with water inlet butterfly valves 8.
In the utility model, the inside of the precision filter 3 is a high-speed filter of a fiber filter material.
In the utility model, the sewage outlets are respectively arranged at the tops of the first coarse filter 1, the second coarse filter 2 and the precise filter 3, and are connected with the sewage collecting pipe 5 through a three-way valve.
In the utility model, the water inlets of the first coarse filter 1, the second coarse filter 2 and the fine filter 3 are all arranged at the top.
In the utility model, the first coarse filter 1, the second coarse filter 2 and the fine filter 3 are all provided with observation windows.
In the utility model, during normal filtration, sewage enters the first coarse filter 1, the second coarse filter 2 and the precise filter 3 from the top pipeline, is filtered by a filter material and is discharged from the bottom, after a period of filtration, the pressure difference between the front and the rear of the filter is increased after the dirt is accumulated on the first coarse filter 1 and the second coarse filter 2, the cleaning state is triggered after the pressure difference exceeds a set value, the dirt is brushed off by rotating a plurality of internal steel brushes of the first coarse filter 1 and the second coarse filter 2 and is discharged along with a blow-off valve, compacted filter material is washed away by water entering from the bottom during backflushing, the filter material is suspended in the tank body, the rotating part of a hydraulic motor rotates during backflushing, the filter material in the precise filter 3 is rotationally cleaned, and backflushing water are discharged through a three-way valve. The first coarse filter 1, the second coarse filter 2 and the precise filter 3 are provided with observation windows, so that the cleanliness of filter materials can be intuitively observed, and the cleaning operation can be manually controlled.
