Example two
The invention relates to a multidimensional filtration method of garbage penetrating fluid, which mainly comprises the following steps:
step one, the injection electric control valve 501 and the clear liquid electric control valve 604 are opened, the turbid liquid enters the turbid liquid cavity 101, the first azimuth filter screen 401 filters large turbid matters (the turbid matters with the size larger than the mesh size of the first azimuth filter screen 401 are large turbid matters), the second azimuth filter screen 402 filters fine turbid matters in the turbid liquid without the large turbid matters (the turbid matters with the size larger than the mesh size of the second azimuth filter screen 402 and smaller than the mesh size of the first azimuth filter screen 401 are small turbid matters), the fine turbid matters stagnate between the first azimuth filter screen 401 and the second azimuth filter screen 402), and clear liquid (clear liquid is formed after the turbid liquid is filtered by the first azimuth filter screen 401 and the second azimuth filter screen 402) is discharged from the clear liquid cavity 102, the first branch pipe 601 and the second branch pipe 603 (recycling can be performed).
In the second step, when the first azimuth filter screen 401 or the second azimuth filter screen 402 is blocked, the turbid liquid continuously injected into the turbid liquid chamber 101 generates side pressure to the lateral end piston plate 203, when the distance parameter sensed by the distance sensing module 205 is reduced to a certain value (at this time, the lateral end piston plate 203 is close to the fixed guide frame 201, the second tension spring 204 is in a compressed state), the injection pipe 5 stops injecting the turbid liquid into the turbid liquid chamber 101, the injection electric control valve 501 is closed, the second magnetic plate 206 is repulsive force generated by the inner periphery electromagnetic mechanism 3, the lateral end piston plate 203 is pushed to the filter screen cylinder 4 by a certain distance (after the lateral end piston plate 203 moves to the filter screen cylinder 4, the movement is stopped), and the liquid in the turbid liquid chamber 101 is further filtered into the clear liquid chamber.
After the clear liquid in the clear liquid cavity 102 is discharged in the third step, the inner periphery electromagnetic mechanism 3 is powered off and loses magnetism, the clear liquid electric control valve 604 is closed, the injection electric control valve 501 and the diversion electric control valve 701 are opened, a certain amount of clear water is injected, the turbid liquid cavity 101 is washed once, and then the diversion electric control valve 701 is closed again.
In the fourth step, the hydraulic mechanism 10 releases the hydraulic pressure to the side wall sealing member 109, the peripheral electromagnetic mechanism 8 magnetically attracts the guide slat 103, the servo motor 9 drives the filter screen cylinder 4 to rotate 180 degrees (after turning 180 degrees, the side of the first azimuth filter screen 401 or the second azimuth filter screen 402, which is blocked, turns to the clear liquid cavity 102), the peripheral electromagnetic mechanism 8 is powered off, the guide slat 103 resets (the guide slat reset means that the first magnetic plate 105 of the guide slat 103 is no longer magnetically attracted by the peripheral electromagnetic mechanism 8 and is acted by the first tension spring 107, the guide slat 103 is pressed again to contact the partition flat plate 403), and the hydraulic mechanism 10 hydraulically drives the side wall sealing member 109 to press the side end sealing disc 404 and the guide slat 103 and lock the hydraulic state.
Step five, continuously injecting clear water into the turbid liquid cavity 101 through the injection pipe 5 until the distance parameter sensed by the distance sensing module 205 is reduced to a certain value, stopping injecting clear water into the turbid liquid cavity 101 through the injection pipe 5, closing the injection electric control valve 501 (in this state, the clear water in the turbid liquid cavity 101 has pushed the lateral end piston plate 203 to a position close to the fixed guide frame 201, the clear water in the turbid liquid cavity 101 has a certain water pressure), opening the turbid liquid electric control valve 606, simultaneously generating repulsive force on the second magnetic plate 206 by the inner peripheral electromagnetic mechanism 3, pushing the lateral end piston plate 203 to a certain distance towards the filter screen cylinder 4, extruding and falling off the first-direction filter screen 401 or the second-direction filter screen 402 towards the blockage on the side of the clear liquid cavity 102, entering the clear liquid cavity 102, and discharging from the first branch pipe 601 and the third branch pipe 605 (if the inner side of the second-direction filter screen 402 of the original fine mesh is blocked, after being extruded, the fine blockage can be smoothly discharged into the turbid liquid cavity 101 from the large mesh of the first-direction filter screen 401).
In the sixth step, the photoelectric sensing module 602 senses the turbidity of the liquid entering the first branch pipe 601 in the fifth step (the photoelectric sensing method senses the turbidity of the liquid, which is more commonly used in the technical field of liquid turbidity detection, and is not repeated in the invention), when the turbidity liquid cavity 101 and the clear liquid cavity 102 are completely discharged, the photoelectric sensing module 602 senses the turbidity of the liquid not lower than a certain parameter value, and then the clean water injection and the pressurization dredging operation in the fifth step are performed again until the turbidity of the liquid sensed by the photoelectric sensing module 602 is lower than the certain parameter value, and then the clean water injection and the pressurization dredging operation are stopped.
Step seven, repeating the driving operation in step four once, adjusting the first azimuth filter screen 401 to the azimuth towards the turbid liquid cavity 101, adjusting the second azimuth filter screen 402 to the azimuth towards the clear liquid cavity 102, and continuing the turbid liquid normalized filtering operation.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
