The space of the clean area of pharmaceutical factory is the important step of pharmaceutical production quality assurance, in the aseptic pharmacy of China GMP, explicitly points out: in drug production process, should reduce product by the danger of dust particle or microbial contamination as far as possible.In toilet, in order to obtain local higher level clean-up effect, conventionally adopt hundred grades of laminar flow hood to realize; And it is tight not to find that in relevant authentication testing process hundred grades of laminar flow hood and high efficiency particulate air filter junction seal, often have serious leakage phenomenon.And the work of existing hundred grades of laminar flow hood replacing filters is comparatively loaded down with trivial details, is not easy to operation.
Utility model content:
The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and hundred grades of laminar flow hood of negative pressure of can side changing filter are provided.
The utility model is realized the technical scheme that its object adopts: a kind of hundred grades of laminar flow hood of negative pressure of can side changing filter, the high efficiency particulate air filter that it comprises inner cover, is arranged on the centrifugal blower on inner cover and is positioned at inner cover bottom, outside in described inner cover is also provided with outer cover, between described outer cover and inner cover, form a negative pressure space, the two side ends of outer cover is provided with air intake orifice plate; The bottom margin of described outer cover has inside flange and forms outer cover flange, and the bottom of described inner cover has outside flange and forms inner cover flange; The upper and lower surface edge of described high efficiency particulate air filter is respectively with air intake surface sealing strip and outlet air surface sealing strip, described high efficiency particulate air filter is arranged between the inner cover flange of inner cover and the outer cover flange of outer cover, and air intake surface sealing strip on high efficiency particulate air filter, outlet air surface sealing strip respectively with inner cover flange and the pressing of outer cover flange; Between the top of described inner cover and the inner top of outer cover, be also connected with adjustable suspension rod.
Described adjustable suspension rod comprises the upper screw rod and the lower screw rod that are arranged on respectively outer cover inner top surface and the outer end face of inner cover, and the revolving part being connected with upper screw rod, lower screw flight simultaneously.
The side surface of described outer cover is also provided with PAO and detects hole, PAO hand-hole, several differential pressure indicator and control panel.
The top outer of described outer cover is also provided with several suspension ring.
The utility model can adopt negative pressure structure, coordinates the tight pressing sealing of high efficiency particulate air filter air intake surface and outlet air surface, can guarantee not occur leakage phenomenon, simultaneously, adopt the utility model mounting structure, can carry out easily replacing and the maintenance work of filter, reduce labour intensity.
Brief description of the drawings:
Fig. 1, Fig. 2 are planar structure schematic diagrames of the present utility model;
Fig. 3 is the partial enlarged drawing at A place in Fig. 1.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1-Figure 3, hundred grades of laminar flow hood of negative pressure of can side changing filter described in the utility model comprise inner cover 1, are arranged on the centrifugal blower 2 on inner cover 1 and are positioned at the high efficiency particulate air filter 3 of inner cover 1 bottom, outside in described inner cover 1 is also provided with outer cover 4, between described outer cover 4 and inner cover 1, form a negative pressure space 100, the two side ends of outer cover 4 is provided with air intake orifice plate 41; The bottom margin of described outer cover 4 has inside flange and forms outer cover flange 42, and the bottom of described inner cover 1 has outside flange and forms inner cover flange 11; The upper and lower surface edge of described high efficiency particulate air filter 3 is respectively with air intake surface sealing strip 31 and outlet air surface sealing strip 32, described high efficiency particulate air filter 3 is arranged between the inner cover flange 11 of inner cover 1 and the outer cover flange 42 of outer cover 4, and air intake surface sealing strip 31 on high efficiency particulate air filter 3, outlet air surface sealing strip 32 respectively with inner cover flange 11 and 42 pressings of outer cover flange; Between the inner top of the top of described inner cover 1 and outer cover 4, be also connected with adjustable suspension rod 5; By the length variations of adjustable suspension rod 5, can regulate the pressing degree between inner cover 1 and high efficiency particulate air filter 3 and outer cover 4, also can regulate inner cover 1 is hanged, unclamp high efficiency particulate air filter 3 simultaneously, at this moment just can change filter, and then readjust suspension rod 5 make it compress.
Described adjustable suspension rod 5 comprises the upper screw rod 51 and the lower screw rod 52 that are arranged on respectively outer cover 4 inner top surfaces and inner cover 1 outer end face, and the revolving part 53 being threaded with upper screw rod 51, lower screw rod 52 simultaneously.Rotate when revolving part 53, upper and lower screw rod is relatively drawn close or separately, is reached the length that regulates whole suspension rod, controls the distance between outer cover and inner cover, thereby controls the sealing between high efficiency particulate air filter and outer cover, inner cover.
The side surface of described outer cover 4 is also provided with PAO and detects hole 43, PAO hand-hole 44, several differential pressure indicator 45 and control panel 46, to the performance of hundred grades of laminar flow hood is detected and controlled its work and shows its operating mode.
The top outer of described outer cover 4 is also provided with several suspension ring 47, is convenient to the lifting of whole hundred grades of laminar flow hood.
While using the utility model, in the time of dismounting air intake orifice plate 41, just can rotate the revolving part 53 of adjustable suspension rod 5, inner cover 1 is moved upward, unclamp the high efficiency particulate air filter 3 of its bottom, now filter can be gone out from air intake orifice plate 41 side-draws, again new filter is packed into from this side, the outlet air surface sealing strip 32 of high efficiency particulate air filter 3 lower surfaces and the outer cover flange 42 of outer cover 4 are alignd, rotate backward again revolving part 53, the inner cover flange 11 that makes inner cover 1 bottom progressively with high efficiency particulate air filter 3 on 31 pressings of air intake surface sealing strip, finally again load onto air intake orifice plate 41.Therefore whole process is simple and efficient, leicht fallen D/A.
The utility model can adopt negative pressure structure, coordinate the tight pressing sealing of high efficiency particulate air filter air intake surface and outlet air surface, extraneous air only can be inhaled into negative pressure space, and can below high efficiency particulate air filter, not enter working region, therefore there will not be leakage phenomenon, can guarantee that working region simultaneously, adopts the utility model mounting structure, can carry out easily replacing and the maintenance work of filter, reduce labour intensity.
