Description

Centrifugal net type filtering device

Technical Field

The utility model relates to a filter equipment technical field specifically is a centrifugal net formula filter equipment.

Background

The principle of the centrifugal filter is as follows: the filter is based on the working principle of gravity and centrifugal force to remove solid particles heavier than water. Water enters the centrifuge body tangentially from the water inlet pipe, and rotates to generate centrifugal force, so that silt and other solid particles with higher density are pushed to move towards the pipe wall to form rotational flow, sand and stones are promoted to enter the sand collecting tank, and clear water flows downstream to enter the water outlet, so that water-sand separation is completed.

The filtering effect of the centrifugal filter is mainly influenced by the capability of manufacturing the vortex, the water outlet points of the pump water are concentrated aiming at the existing centrifugal filter, and the original vortex is easily broken when the suction force is too large, so that the filtering effect is reduced.

Therefore, we propose a centrifugal screen filter device to improve the filtration effect.
