Abstract
The utility model relates to a high-efficiency air exhaust opening of a zero pressure sealed side frame. The utility model is composed of a still pressure box, a high-efficiency filter and a sealing side frame. The utility model is characterized in that the upper edge of the sealed side frame is provided with a sealed gasket and a sealed framework used for supporting the high-efficiency filter, and a cylindrical outer wall of the sealed side frame is provided with pressure relief holes communicated with a technical sandwich layer of a ceiling; the lower edge of the sealed side frame is provided with a locking device, a pressing framework and a pressing sealed gasket, and a zero pressure zone is formed in a long narrow space between the sealed side frame and the periphery of the high pressure filter. The utility model has the advantages of reasonable structure and simple structure, the high-efficiency filter can be assembled and disassembled conveniently, and tiny air flow leakage is avoided. The utility model is suitable for the air exhaust opening of the clean space of a purification system.
Description
The utility model belongs to the air outlet to room or place importing air, and particularly a kind of air outlet that is used for the cleaning system clean room also claims blowing unit.
At present, the end of the supply air system of clean room connects high efficiency particulate air filter by plenum chamber and constitutes, and promptly becomes air outlet, and this air outlet generally is installed in the ceiling of technology interlayer.Plenum chamber with the structure that is connected of high efficiency particulate air filter is, in the plenum chamber lower end sealed frame is set, fixedly connected high efficiency particulate air filter with press strip with bolt, establish sealing joint strip in the fixed connection place, prevent that air-flow is from the high efficiency particulate air filter frame outside, filtered is handled and is promptly leaked into clean workspace, downstream, forms and pollutes.But, existing sealed frame in the deficiency of the textural existence of structure is, minute leakage appears in the connecting portion of sealed frame and high efficiency particulate air filter frame unavoidably, because the pressure of leakage current is greater than the stream pressure of clean room, the gas of this part minute leakage, just can be lentamente slit by the press strip position enter clean area, pollute.
The purpose of this utility model is, designs and produces a kind of efficient air outlet of zero-pressure sealed frame, improves the sealed frame structure, and the place is provided with region of no pressure at sealed frame, forms leakage pollution thereby the air-flow at the sealed frame place of stopping a leak enters clean area.
The technical solution of the utility model is following realization, and a kind of efficient air outlet of zero-pressure sealed frame is made up of plenum chamber, high efficiency particulate air filter and sealed frame, and the plenum chamber end face is provided with air inlet, and the casing periphery is established adiabator layer, and the lower end connects sealed frame; The sealed frame upper edge is provided with the seal frame of supporting high efficiency particulate air filter, be provided with the filter sealing gasket at high efficiency particulate air filter and seal frame contact site, on the cylindrical outer wall of sealed frame, offering the pressure release hole communicates with the technology interlayer of ceiling, locking device, hold-down frame are set in the sealed frame lower edge and compress sealing gasket, offer bolt hole on the locking device, compress frame and locking device with the bolting connection, the long and narrow space between sealed frame and high pressure filter periphery constitutes region of no pressure.
Using method of the present utility model is, the efficient air outlet of zero-pressure sealed frame is installed in technology interlayer on the room ceiling, because the technology interlayer communicates with atmosphere by its door or window, also just equaling the pressure release hole communicates with atmosphere, its high efficiency particulate air filter is adjacent to seal frame and the filter sealing gasket that the sealed frame upper edge is provided with earlier, again with the hold-down frame of sealed frame lower edge with compress sealing gasket and hold out against the high efficiency particulate air filter lower edge, pass locking device with bolt then, fixedly connected hold-down frame and sealed frame, the long and narrow space between around sealed frame and the high pressure filter constitutes region of no pressure.The air-flow of plenum chamber passes through high efficiency particulate air filter on the one hand, simultaneously, small airflow leakage is arranged between sealed frame and the high efficiency particulate air filter frame, because existing pressure release hole communicates with the technology interlayer on the wall in this space, so this part small air-flow just can enter the technology interlayer by the pressure release hole on the sealed frame outer wall, this space promptly forms region of no pressure, does not have pressure again and is pressed into clean area, has guaranteed the cleanliness factor of clean area air-flow.
The utility model has the advantages that, rational in infrastructure, simple structure, the mounting or dismounting high efficiency particulate air filter is easy to operate, stops small airflow leakage.Be applicable to the air outlet of cleaning system clean room.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of the efficient air outlet of zero-pressure sealed frame of the present utility model
Fig. 2 is the detail of construction of node A among Fig. 1
By Fig. 1,2 as seen, a kind of efficient air outlet of zero-pressure sealed frame is made up of plenum chamber, high efficiency particulate air filter and sealed frame, and the plenum chamber end face is provided with air inlet 11, is provided with suspension ring 1 are installed, and casing 2 peripheries are established adiabator layer 3, and the lower end connects sealed frame; The sealed frame upper edge is provided with the seal frame 4 of supporting high efficiency particulate air filter, be provided with filter sealing gasket 5 at high efficiency particulate air filter and seal frame contact site, on the cylindrical outer wall of sealed frame, offering pressure release hole 10 communicates with the technology interlayer of ceiling, locking device 7, hold-down frame 9 are set in the sealed frame lower edge and compress sealing gasket 8, offer bolt hole on the locking device, with bolt 12 fixedly connected frame and the locking devices of compressing, the long and narrow space between sealed frame and high pressure filter periphery constitutes region of no pressure.
