Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 3 Fig. 4 Fig. 5, a kind of new fluid slotting sealed laminar flow casing, comprise laminar flow hood shell 1, sealed knife frame-saw 5 and flume seal filter 3, the upper portion side wall of shell 1 is respectively arranged with return air hole 11, flume seal filter 3 is fixed on the inner chamber bottom surface of shell 1 through sealed knife frame-saw 5, shell 1 bottom of flume seal filter 3 belows is outlet air surface, and the upper end of sealed knife frame-saw 5 and flume seal filter 3 are tightly connected, and the lower end of sealed knife frame-saw 5 is connected with shell 1 inner chamber sealing bottom surface.
Flume seal filter 3 tops are provided with liquid bath 6, and the upper end Edge Bend of sealed knife frame-saw 5 inserts on this in liquid bath 6, is marked with flume seal glue 9 on this in liquid bath 6, make sealed knife frame-saw 5 form and be sealed and matched with flume seal filter 3.Between the upper end of sealed knife frame-saw 5 and flume seal filter 3, be connected and fixed through installed part 8, the limit, upper end of sealed knife frame-saw 5 can be positioned in upper liquid bath 6 by installed part 8.
After the lower end Edge Bend of sealed knife frame-saw 5, adopt spot welding to fix with the bottom surface of shell 1 inner chamber, between sealed knife frame-saw 5 and shell 1 inwall, form lower liquid bath 7, at the interior injection liquid bath sealant 9 of this lower liquid bath 7, make sealed knife frame-saw 5 form and be tightly connected with shell 1 inwall.
Sealed knife frame-saw 5 comprises four knife rest frames 51, between adjacent two knife rest frames 51, forms and is tightly connected through continuous welding.
