Abstract
The utility model relates to an airflow-inducing frame-leakage-free high efficiency air supply outlet. The airflow-inducing frame-leakage-free high efficiency air supply outlet comprises an outer box sheet metal box body, a filter and sealing strips. The airflow-inducing frame-leakage-free high efficiency air supply outlet further comprises a supporting induction frame. The inner side of the supporting induction frame supports the section bar outer frame of the filter and one sealing strip, the outer side of the supporting induction frame supports the sealing strip on the connection portion of the outer box sheet metal box body, and therefore an airflow induction area is formed between the outer box sheet metal box body and the filter. A plurality of open holes are formed in the outer side of the outer box sheet metal box body so that the airflow induction area can be communicated with a technical interlayer on the outer side of the outer box sheet metal box body. The airflow-inducing frame-leakage-free high efficiency air supply outlet completely avoids airflow leakage of the mounting frame of the high efficiency filter, and eliminates the hidden danger that leakage happens after a mist opening and a detecting opening are used for a long time and are aged.
Description
Technical field
The utility model relates to a kind of efficient air outlet, is specifically related to a kind of air-flow and induces no frame to leak efficient air outlet.
Background technology
Efficient air outlet is thousand grades, ten thousand grades, the 100000 grades end-filtration devices that air cleaning and conditioning system is comparatively desirable, can be extensively in the air cleaning and conditioning system of industries such as medicine, health, electronics, chemical industry.Efficient air outlet is the end-filtration device as transformation and newly-built 1000-300000 level toilets at different levels, is to satisfy to purify the key equipment that requires.Efficient air outlet comprises plenum chamber, diffuser plate, and high efficiency particulate air filter can be apical grafting or side joint with the interface of airduct.
The sealing that high efficiency particulate air filter is installed frame is the key point of efficient air outlet, and the frame seal defect will cause installing frame leaks, and can influence the cleanliness factor of toilet.
At present, traditional efficient air outlet mainly contains two kinds of frame seal form, and namely sealing strip compresses seal form and liquid bath seal form.
First kind of form needs pressured tight strip of paper used for sealing to reach the sealing of filter frame, make the air of filter upstream under certain malleation drives, enter the toilet through high efficiency particulate air filter, and do not enter the toilet by high efficiency particulate air filter with the sealing place bypass that is connected of air outlet casing.The crack of any sealing edge own, out-of-flatness, thrust inadequately, too compress the existence that quality problems of causing edge strain cracking or sealing strip etc. all can cause frame to leak.
Second kind of form, relative first kind of mode is well a lot, and the introducing of liquid bath sealing has solved greatly and has compressed a lot of problems that sealing can occur, such as the control of thrust, frame strain cracking etc.Granted publication number discloses a kind of liquid bath hermetically-sealed construction in the utility model patent of CN202203400U, comprises air outlet and filter, and the filter side is provided with and is filled with jelly shape fluid sealant in the seal groove seal groove.It has overcome the defective that sealing strip compresses seal form to a certain extent.
But liquid bath seal form still frequent problem in the actual installation scene occurs, and scans repeatedly the liquid bath sealing afterwards of dismounting filter such as detection and is easy to generate leakage, and the quality problems of liquid bath glue own are leaked etc.
Along with appearance and the enforcement of national new edition " GMP " (being the GMP standard), the efficient air outlet of first kind of form has not substantially been adopted by the toilet, pharmaceutical factory owing to its problems.Current more is to adopt second kind of form, i.e. the form of liquid bath sealing certainly, for the needs of on-the-spot test, can increase in its structure and send out mist interface tube and upstream concentration monitor interface.
Granted publication number discloses a kind of efficient air outlet that has instrument connection in the utility model patent of CN201858747U, and the test hole that it is set up can be installed air quantity, filter efficiency checkout gear etc.
But send out mist interface tube and the monitoring interface etc. that increase generally adopt the compressed air fast interface, the second best in quality fast interface of regular producer does not have air and leaks in the time of general new, but along with use, having grown some service time can wear out, so just produced the possibility of leaking, this is a hidden danger for efficient air outlet.
The utility model content
At above shortcomings in the prior art, technical problem to be solved in the utility model provides a kind of air-flow and induces no frame to leak efficient air outlet.
The utility model purpose is achieved by the following technical solution:
A kind of air-flow induces no frame to leak efficient air outlet, comprise the outer container sheet metal box body, filter and sealing strip, described filter is installed in the outer container sheet metal box body, section bar frame and the outer container sheet metal box body fixed edge of the air intake of described filter and air-supply end have sealing strip to compress sealing, described air-flow induces no frame to leak efficient air outlet to comprise that also supporting induces frame, described supporting induces the medial branch of frame to prop up section bar housing and the sealing strip of filter, supporting induces the outside of frame to support the sealing strip of itself and outer container sheet metal box body junction, thereby between outer container sheet metal box body and filter, form air-flow and induce the zone, there are some perforates in the described outer container sheet metal box body outside, makes air-flow induce zone and outer container sheet metal box body to be interlinked to the outside.
Preferably,
Supporting induces frame to pass through screw at 4 angle points, supports section bar housing and the sealing strip of filter.
The diameter of perforate is the circular hole of 3mm, and described perforate is at a distance of one of about 50mm.
Described filter can be conventional high efficiency particulate air filter.
Described air-flow is induced the zone to be provided with and is detected mouth, detect mouth for detection of upstream concentration.
Described air-flow is induced the zone to be provided with and is sent out the mist mouth, sends out the mist of sending out that the mist mouth is used for the upstream.
In the utility model, described air-flow is induced the existence in zone, no matter make it is the poor sealing of filter Upstream section, or the leakage part that the poor sealing of filter tract produces can induce the zone to be discharged to the interlayer zone of non-cleaning via air-flow, has stopped the flow leakage that high efficiency particulate air filter is installed frame.
For detection of the detection mouth of upstream concentration be used for the upstream and send out the mist mouth of sending out of mist and all be arranged on and induce in the zone, can after open corresponding capping, connect detector tube and send out a mist pipe during detection, then cover with capping when not detecting.Like this, just get rid of a mist mouth and detected mouthful aging back of long-term use and produced the hidden danger of leaking.
The utility model compared with prior art has following advantage:
1, the air-flow of the utility model design is induced no frame to leak efficient air outlet and has been stopped the flow leakage that high efficiency particulate air filter is installed frame.
2, got rid of a mist mouth and detect and mouthful long-term to use aging back to produce the hidden danger of leaking.
3, simple structure, project organization is reasonable, and the disassembling, assembling and replacing high efficiency particulate air filter is easy to operate, has thoroughly stopped small airflow leakage.
