Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the present invention is clearly and completely described.
As it is shown in figure 1, a kind of fore filter, including the first universal valve body 1, filter cavity 2 and flushing valve 3, described
First universal valve body 1 includes wastewater inlet 4 and clear water output 5, and described wastewater inlet 4 connects intake tunnel 6, described Graceful
Mouth 5 connects exhalant canal 7, and described first universal valve body 1 connects filter cavity 2 by loose joint cap 8, and described filter cavity 2 wraps
Including the upper drainage screen 11 used when lower drainage screen 10 is opened with flushing valve 3, described lower drainage screen 10 constitutes filter with upper drainage screen 11
Core, described lower drainage screen 10 bottom is provided with the second universal valve body 12, and described second universal valve body 12 bottom is provided with lower filtration
Net support 13, described lower filter screen stand 13 uses spring bracing, described lower filter screen stand 13 to be connected by union joint 14
Flushing valve 3, opens flushing valve 3, and spring bracing can be made to bounce back, and causes lower drainage screen 10 to sink, and now current are from upper part
The outside of filter element enters into the inside of filter element, and on a part of flow direction, drainage screen 11 ensures just to commonly use water, some water
Stream flows to lower drainage screen 10 and carries out backwash, and described upper drainage screen 11 top is provided with regulator.Described regulator includes
