When the filtering operation is carried out, the filtering liquid is added into the water pipe through the water inlet pipe, then sequentially passes through the inner cavity of the collector shell, the conical filter element (the upper conical filter element and the lower conical filter element are collectively called the conical tube and the lower conical filter element) and is discharged onto the filter material layer through the conical tube (the upper conical tube and the lower conical tube are collectively called the conical tube and the lower conical filter element), then the filtering liquid passes through the filter material layer under the influence of gravity and flows out through the water outlet pipe, meanwhile, the water pressure is balanced under the action of the membrane, the flow speed of the filtering liquid is relatively uniform, meanwhile, the water yield difference value of the same conical tube from different positions of the water pipe is relatively smaller under the design of different through hole sizes of the conical filter element (the upper conical filter element and the lower conical filter element are collectively called the conical filter element and the lower conical tube and the same), so that the filtering liquid amount passing through the water pipe in different distances per unit time is smaller, the filtering effect is improved;

in the filtration state: sewage enters the conical collector through the water pipe, enters the upper conical pipe and the lower conical pipe through the upper conical filter element and the lower conical filter element, and flows are shunted through the upper conical pipe and the lower conical pipe to enter the filter material layer very stably;

the method is characterized in that:

1. when water flows into the conical collector through the water pipe, the water impacts the diaphragm under the action of water pressure, the diaphragm shrinks upwards, a buffering effect is achieved, and the water flows into the upper conical pipe and the lower conical pipe stably.

2. The conical pipe and the conical mixer form a certain included angle, the conical pipe is far away from the conical collector and is closer to the filter material layer, the water pressure far away from the conical collector is small, and the water pressure near the conical collector is large, so that water flows with different water pressures can be ensured to flow into the filter material layer with consistent punching force through different distances from the filter material layer, and the water flow with the structure is more stable;

3. the size of the opening of the conical tube is determined according to the distance from the conical collector, the distance from the opening to the conical collector is small, and the distance from the opening to the conical collector is large.

The method is characterized in that:

1. the filter material is intercepted by the upper and lower conical filter screens, so that the material is prevented from leaking, and the intercepted filter material returns to the filter material layer through the bottom hole of the conical collector and the holes of the upper and lower conical filter elements;

2. when water flow enters the conical collector through the upper conical pipe and the lower conical pipe, the diaphragm moves downwards under the action of water pressure, the volume of the conical filter screen is reduced, the suction force of the water flow is increased, and the backwashing effect is better;

2. the conical pipe and the conical mixer form a certain included angle, the conical pipe is far away from the conical collector and is closer to the filter material layer, the suction force far away from the conical collector is small, and the suction force near the conical collector is large, so that water flows with different water pressures can pass through different distances from the filter material layer to ensure the consistency of the suction force, the consistency of the suction force at each place of the filter material layer is ensured, and each place of the filter material layer can be cleaned;

3. the size of the opening of the conical tube is determined according to the distance from the conical collector, the distance from the opening to the conical collector is small, and the distance from the opening to the conical collector is large. The purpose is to make the suction distribution more uniform. The suction close to the conical collector is large, the hole ratio is small, the speed of water flow flowing out of the hole is high, the flow speed is low at a place far from the hole and is large, but the sectional area of the hole is large, so the relative difference of the flow is not large, and the suction at each place of the filter material layer is consistent;

4. the precision of the upper conical filter element is smaller than that of the lower conical filter element, the relative resistance is smaller, the upper conical pipe is farther away from the filter material layer, and the upper conical pipe is consistent with the suction force of the lower conical pipe reaching the filter material layer due to the smaller resistance.
