Abstract
The utility model provides a laminar hood with liquid groove sealing, which comprises a housing, a filter and a draught fan; the utility model is characterized in that: the laminar hood adopts liquid groove type sealing; the inwall of the housing is provided with a bracket whose anterior end is provided with a sealed inserting plate; both ends of the filter is provided with a U-shaped groove, and the sealed inserting plate is arranged in the U-shaped groove; the U-shaped groove is filled with sealing liquid; the U-shaped groove is connected with the bracket through a bolt. The upper plate of the laminar hood adopts the U-shaped groove sealing structure as the housing; the built-in bolts are connected. By adopting the structure laminar hood, the U-shaped groove is matched with the sealed inserting plate; the completely sealing is realized through the sealing liquid; the problem of air leakage from compression zone to the clean area can be avoided.
Description
Technical field
The utility model relates to a kind of air cleaning facility
Background technology
The laminar flow hood of existing air cleaning facility is made up of shell, filter, blower fan.Outlet air surface at filter pastes sealant tape, seals by bolted.This structure can cause poorly sealedly under the firmly uneven situation of fastening bolt, causes the pressure area air to be leaked to clean area in the place of air-proof condition weakness, makes the clean area air purity can not get effective guarantee, causes laminar flow hood to lose due effect.
Summary of the invention
Rely on close adhesive tape and bolted sealing in order to overcome prior art filter outlet air surface, easily cause poorly sealed deficiency and upper plate and body seal deficiency, the utility model provides a kind of liquid bath sealed laminar flow hood.
The technical scheme that its technical problem that solves the utility model adopts is: laminar flow hood adopts the liquid tank type sealing, set support front end is established the sealing plate on its outer casing inner wall, " U " shape groove is established at the filter two ends, the sealing plate places in " U " shape groove, perfusion sealing fluid in " U " shape groove, " U " shape groove is by bolt attachment bracket, and laminar flow hood upper plate and shell adopt " U " shape slot sealing arrangement equally, and built-in bolt connects.
Adopt good effect of the present utility model to be: " U " shape groove cooperates with the sealing plate, has realized sealing fully by sealing fluid, the problem of having avoided the pressure area air to leak to clean area.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the figure 1 be the air intake flange, 2 for upper plate, 3 for last " U " shape groove, 4 for blower fan, 5 for fluid sealant, 6 for the sealing plate, 7 for " U " shape groove, 8 for bolt, 9 for sealing fluid, 10 for filter, 11 for the laminar flow hood shell, 12 for the diffusion hollow plate.
The specific embodiment
Air intake flange (1), laminar flow hood shell (11), upper plate (2), diffusion hollow plate (12) all adopt steel plate to make, laminar flow hood shell (11) is gone up the inboard, top and is established " U " shape groove (3), the outer side seal plate of upper plate (2) places in " U " shape groove (3), " U " shape groove (7) is established at filter (10) two ends, support forward end seal plate (6) places in " U " shape groove (7), perfusion non newtonian sealing fluid (9) in " U " shape groove is realized sealing fully.Support is fastenedly connected by bolt (8) with " U " shape groove, and the steel plate of support and built-in carrying blower fan 4 and the weld of laminar flow hood inwall all adopt resin-sealed glue (5) sealing.
Claims (2)
1, a kind of liquid bath sealing laminar flow hood, form by shell, filter, blower fan, it is characterized in that: laminar flow hood adopts the liquid tank type sealing, set support front end is established the sealing plate on its outer casing inner wall, " U " shape groove is established at the filter two ends, the sealing plate places in " U " shape groove, perfusion sealing fluid in " U " shape groove, and " U " shape groove passes through bolt attachment bracket.
2, according to the described liquid bath sealing of claim 1 laminar flow hood, it is characterized in that: laminar flow hood upper plate and shell adopt " U " shape slot sealing arrangement equally, and built-in bolt connects.
