Middle setting filter device comprising collecting space is separated into filter space and collecting space by a filter screen, the filter screen.
For the filter device, further, the filter screen is the strainer being obliquely installed from the top down, in the mistake
It filters and a water-distributing cover is set above the filter screen in space, which separates the water inlet of the header tank and filter screen, in this point
There are a spaces between the wire side of the upper end of the lower edge and filter screen of water cover, so that secondary water flows through the water-distributing cover,
Then it is crossed from the top for the filter screen being obliquely installed in filtering web stream and enters collecting space；The institute being obliquely installed
The lowest order for stating filter screen installs the overflow port.
Further, the entire edge in the lower end of the water-distributing cover is corresponding with the entire upper end-face edge of the filter screen, makes
Obtaining secondary water is to flow from the top to the bottom on the entire wire side of the filter screen.
Closer, the filter screen is the conical filter net being arranged on the horizontal plane of the header tank, the taper
