Utility model content
For the problems referred to above, the utility model proposes the double-deck laminar flow hood of a kind of steady type.
For solving this technical problem, the utility model takes following scheme: the double-deck laminar flow hood of a kind of steady type, comprise shell, inner casing and sealed knife frame-saw, described inner casing is arranged in the enclosure through sealed knife frame-saw, the sealed knife frame-saw being positioned at shell is provided with flume seal filter, form negative pressure cavity between described shell and inner casing, between described inner casing and flume seal filter, form malleation chamber;
Described sealed knife frame-saw and the mounting structure between inner casing and flume seal filter are: form erecting bed in the upper end of sealed knife frame-saw, this erecting bed is formed a circle liquid bath, the bottom of described flume seal filter forms circle first sealing ring, and this first sealing ring is arranged in described liquid bath; The bottom of described inner casing forms lower erecting bed, and this lower erecting bed is formed circle second sealing ring, and this second sealing ring is arranged in described liquid bath, is provided with flume seal glue in described liquid bath, and flume seal glue did not have the bottom of two sealing rings.
Further, described flume seal filter and be connected and fixed through the first some screws between upper erecting bed, flume seal filter bottom end offers screwing through hole, upper erecting bed is formed screw blind hole, and the first screw is connected with upper erecting bed through being selected into after screwing through hole in screw blind hole.
Further, be connected and fixed through several second screws between described sealed knife frame-saw and inner casing, the upper erecting bed of sealed knife frame-saw forms screwing through hole, the lower erecting bed of inner casing forms screw blind hole, and the second screw is connected with the upper erecting bed of inner casing through being selected into after screwing through hole in screw blind hole.
By adopt preceding solution, the beneficial effects of the utility model are: the use of saving conventional attachment, make flume seal filter more stable be fixed on sealed knife frame-saw, also improve the sealing in malleation chamber simultaneously.

Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 3 Fig. 4 the present embodiment, the double-deck laminar flow hood of a kind of steady type is disclosed, comprise shell 1, inner casing 2 and sealed knife frame-saw 3, inner casing 2 is arranged in shell 1 through sealed knife frame-saw 3, the sealed knife frame-saw 3 being positioned at shell 1 is provided with flume seal filter 4, form negative pressure cavity between shell 1 and inner casing 2, between inner casing 2 and flume seal filter 4, form malleation chamber.
Sealed knife frame-saw 3 and the mounting structure between inner casing 2 and flume seal filter 4 are: form erecting bed in the upper end of sealed knife frame-saw 3, this erecting bed is formed a circle liquid bath, the bottom of flume seal filter 4 forms circle first sealing ring, and this first sealing ring is arranged in liquid bath; The bottom of inner casing 2 forms lower erecting bed, and this lower erecting bed is formed circle second sealing ring, and this second sealing ring is arranged in liquid bath, is provided with flume seal glue 5 in liquid bath, and flume seal glue 5 did not have the bottom of two sealing rings.Flume seal glue 5 is water sample material before solidifying, and therefore, all gaps can complete tight shutoff, and flume seal glue 5 is non-newtonian liquid, and be g., jelly-like after condensation, have the feature of not transmitting force, sealing effectiveness is excellent.
Be connected and fixed through the first some screws 6 between flume seal filter 4 and upper erecting bed, flume seal filter 4 bottom offers screwing through hole, upper erecting bed is formed screw blind hole, and the first screw 6 is connected with upper erecting bed through being selected into after screwing through hole in screw blind hole.Blind hole structure on upper erecting bed can effectively avoid barotropic gas to let out through screw.
Be connected and fixed through several second screws 7 between sealed knife frame-saw 3 and inner casing 2, the upper erecting bed of sealed knife frame-saw 3 forms screwing through hole, the lower erecting bed of inner casing 2 forms screw blind hole, and the second screw 7 is connected with the upper erecting bed of inner casing 2 through being selected into after screwing through hole in screw blind hole.Blind hole structure on lower erecting bed can effectively avoid barotropic gas to let out through screw.
Save the use of conventional attachment, make flume seal filter 4 more stable be fixed on sealed knife frame-saw 3, also improve the sealing in malleation chamber simultaneously.
And in laminar flow hood of the present utility model, the mounting structure between sealed knife frame-saw 3, flume seal filter 4 and inner casing 2 can be more simple, improves packaging efficiency.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
