Further, in the utility model discloses in positioning bolt's nut part is established at the filter screen inboard, and positioning bolt's preceding end is vertical to be pushed up on the filter urceolus inner wall.
Further, in the utility model discloses in 4 groups are set to welding formula bolt positioner's quantity, and 4 groups welding formula bolt positioner are the even interval arrangement of annular.
Further, the utility model discloses in every group welding formula bolt positioner in the set nut all be equipped with two, two set nuts correspond the welding on the inside and outside both sides lateral wall of filter screen.
Further, in the utility model discloses in welded type bolt positioner from last 1/4 ~ 1/3 departments that extremely down mounting height is filter screen length.
The structure of the utility model leads the integral installation mode to adopt the split installation mode, can better fix the filter screen part of the filter, effectively avoids the situation that the bottom of the filter screen of the filter is deformed or damaged due to installation dislocation, and leads the Y-shaped filter to have the effect of filtering without dead angles; the utility model discloses though improve very simply, the result of use is obvious, has fine in-service use and spreading value.
