Abstract
The utility model discloses a hundred grades of laminar flow hood, include the outer container and locate the static pressure case of bottom in the outer container, the static pressure case with the junction of outer container is connected for the full weld, fan and early effect filters are equipped with to the interior top of outer container, the top surface of static pressure case is equipped with the cistern filter, the bilayer membrane that flow equalizes is equipped with to the bottom surface of static pressure case, the LED lamp still is equipped with on the inner wall of static pressure case, the cistern filter pass through location support board and bolt fastening in on the static pressure case, the bilayer flow equalizes on the membrane locates the static pressure tank wall through the torsion spring card. The bilayer flow equalizes, and the membrane passes through torsion spring, the cistern filter passes through the bolt and all can follow the installation of static pressure bottom of the case portion, simple structure, and the installation is maintained portably, full weld between outer container and the static pressure case adopts the cistern filter simultaneously for sealing performance between static pressure case and the outer container is good, the bilayer flow equalizes the membrane makes the air current more even, and the LED lamp is adorned in the static pressure incasement, and light sees through the bilayer and flow equalizes more even softly behind the membrane.
Description
Technical field
The utility model relates to air cleaning facility technical field, specifically refers to a kind of hundred grades of laminar flow hood.
Background technology
Laminar flow hood is that air by after high efficiency particulate air filter, is formed equal fluid layer with wind speed definitely, makes pure air be vertical one-way flow, thus ensure that in workspace a kind of air cleaning facility of the cleanliness factor reaching technological requirement; Hundred grades of clean lamellar flow covers are under low cleanliness factor environment, create the device of local high-cleanness, high environment, partial duty environment can be made to reach hundred grades.Hundred grades of laminar flow hood are very high for the requirement of sealing, leak, namely cause all operations to lose efficacy once exist.Therefore, existing laminar flow hood, in order to ensure its sealing, often makes structure comparatively complicated.
Utility model content
The purpose of this utility model is to provide simple and hundred of the good airproof performance grades of laminar flow hood of a kind of structure.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of hundred grades of laminar flow hood, comprise outer container and the plenum chamber being located at described outer container inner bottom part, described plenum chamber and the junction of described outer container are that full weld is connected, the inner top of described outer container is equipped with blower fan and roughing efficiency air filter, the end face of described plenum chamber is equipped with liquid bath filter, double-deck current-sharing film is equipped with in the bottom surface of described plenum chamber, the inwall of described plenum chamber is also equipped with LED, described liquid bath filter is fixed on described plenum chamber by positioning support fagging and bolt, and described double-deck current-sharing film is arranged on static pressure tank wall by torsionspring.
The beneficial effect of the technical program is: double-deck current-sharing film all can be installed by bolt by torsionspring, liquid bath filter bottom plenum chamber, and structure is simple, and installation and maintenance are easy; Full weld between outer container and plenum chamber, adopts liquid bath filter simultaneously, makes the good seal performance between plenum chamber and outer container; Double-deck current-sharing film make air-flow evenly, and LED is loaded in plenum chamber, evenly soft after the double-deck current-sharing film of light therethrough.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is hundred grades of laminar flow hood structural representations;
Fig. 2 is the close-up schematic view of A in Fig. 1.
Detailed description of the invention
With reference to the hundred grades of laminar flow hood of the one shown in Fig. 1 and 2, comprise outer container 1 and the plenum chamber 2 being located at described outer container 1 inner bottom part, described plenum chamber 2 and the junction of described outer container 1 are that full weld is connected, the inner top of described outer container 1 is equipped with blower fan 3 and roughing efficiency air filter 4, the end face of described plenum chamber 2 is equipped with liquid bath filter 5, double-deck current-sharing film 6 is equipped with in the bottom surface of described plenum chamber 2, the inwall of described plenum chamber 2 is also equipped with LED 7, described liquid bath filter 5 is fixed on described plenum chamber 2 by positioning support fagging 8 and bolt 9, described double-deck current-sharing film 6 is arranged on plenum chamber 2 wall by torsionspring 10.Double-deck current-sharing film 6 all can be installed by bolt 9 by torsionspring 10, liquid bath filter 5 bottom plenum chamber 2, and structure is simple, and installation and maintenance are easy; Full weld between outer container 1 and plenum chamber 2, adopts liquid bath filter 5 simultaneously, makes the good seal performance between plenum chamber 2 and outer container 1; Double-deck current-sharing film 6 make air-flow evenly, and LED 7 is loaded in plenum chamber 2, evenly soft after the double-deck current-sharing film 6 of light therethrough.This laminar flow hood is also provided with leak detection system, and whether convenient detection between outer container and plenum chamber leaks.This laminar flow hood is also provided with pressure detecting system, is convenient to detection and control stream pressure, makes air-flow evenly stable.Described blower fan 3 is provided with damper, reduces noise and enhances the stability of operation.Described outer container 1 end face is also provided with suspension ring 11, is convenient to the installation of laminar flow hood.
Above embodiment is just to illustrate instead of restriction the utility model, therefore all equivalences done according to the method described in the utility model patent claim change or modify, and are included in the utility model patent claim.
Claims (5)
