Embodiment
With reference to Figure of description 1; it shows a kind of detector of biosafety barrier material; this detector is mainly by testing equipment 12; clean protected location and provide the compressed gas source of compressed gas to form to the Vib. 19 of testing equipment; wherein testing equipment is installed in the operation room of an airtight band door; and this operation room close on the door part be provided with air hole 20; this air hole is used for being connected to described clean protected location by negative pressure channel; should then comprise a fan 17 and the last filtrator 1 that is disposed at this fan exhausr port at least by the cleaning protected location, be used to form the negative pressure of described negative pressure channel.
Testing equipment is disclosed by pharmaceuticals industry standard YY/T0506.5-2009, the rubber that comprises some test chambers, a marble slab 16, support marble slab, wherein test chamber is fixed on the marble slab by fixed head, Vib. is set on marble slab simultaneously, Vib. uses usually and opens the moving ball type oscillator, output vibration frequency height, according to the regulation of above-mentioned standard, said frequency is 347Hz.
Further, on the basis of above-mentioned base case, those skilled in the art can select or make up following technological means:
For ease of adjusting and integrating, described clean protected location also comprises the protection chamber 3 that is communicated in described negative pressure channel, and a panel of this protection chamber is equipped with described filtrator and the fan gone up, and is outdoor gas is discharged this protection.
Preferably; be with in the cabinet type housing 11 of dividing plate 7 in the middle of described operation room and described protection chamber are formed at one; its median septum upside forms described protection chamber; downside forms described operation room; and dividing plate is provided with air intake opening and is positioned at the indoor following blower fan 4 of protection; the following filtrator 5 of the exhausr port of this time blower fan through being arranged on the dividing plate is communicated to operation room; thereby; can guarantee to form in the operation room malleation; easier of testing equipment provides clean protection, also reduce fan and reached the burden that goes up filtrator.In addition, the conveying air quantity of negative pressure channel is greater than down the exhaust air rate of blower fan, so said malleation is local malleation, and still can form negative pressure in this case near door, the air of outside can enter, and can form air curtain herein.
Mention fan and be installed on the panel protecting the chamber though it is noted that the front here, according to the understanding of routine, fan is installed on the door obviously improper, and door is movable.And be installed on low panel, just the dividing plate of being mentioned in the literary composition is also improper, must form conflict.Consider that from the body of cabinet body structure operation room other four panels except that this two panels all can be installed blower fan, certain, for better shunting, it is more suitable that fan is installed on top panel.
In order to satisfy standard-required, at least be not less than standard-required, the described filtrator of going up is selected from a kind of of HEPA or ULPA with following filtrator, HEPA (High efficiency particulate air Filter) wherein, the Chinese meaning is high efficiency particle air filter, reaches the screen pack of HEPA standard, reaches 99.998% for the efficient of 0.1 micron and 0.3 micron, the characteristics of HEPA net are that air can pass through, but tiny particulate can't pass through.It is that 0.3 micron (hair diameter 1/200) above particle removal efficiency can reach more than 99.7% to diameter, is the most effective filtering mediums of pollutant such as smog, dust and bacterium (the smoke particle diameter that produces of smoking is 0.5 micron).It is the high efficiency filter material of generally acknowledging in the world.Through extensively applying to operating room, Animal Lab., crystal experiment and the contour clean place of aviation.And be the ultra high efficiency air strainer for ULPA (Ultra Low Penetration Air Filter) full name, or claim ultralow penetrance air strainer, the filtration efficiency of the dust particles such as particulate, smog and microorganism of 0.1～0.2 μ m is reached more than 99.999%.ULPA ultra high efficiency screen pack, ULPA be on the basis of HEPA through further having strengthened the filter effect of HEPA, ULPA reaches more than 99.9999% the atomic filtration efficiency more than 0.3 micron.ULPA compares with HEPA, and filter structure is compacter, filtration efficiency is higher.The ulpa filter filter area is bigger, and dust capaciting ability is stronger.The ulpa filter characteristics: filter core forms with ultra-fine fibre glass filtrate economy-combat glue is folding, housing can be selected interlayer plank, zinc-plated copper coin, corrosion resistant plate and aluminium alloy plate for use, closely bond by polyurethane adhesive, have light weight, Air permenbility is big, dust collection efficiency is up to 99.95-99.999%, and it is alkaline-resisting, high temperature resistant.Purposes: be applicable to 10000 grades of-100 grades of clean systems, air-conditioning system, so product has been widely used in electronics, microelectronics, semiconductor, optical device, biology and a plurality of fields such as medical circuit, camera and optical instrument, precision optical machinery etc.
Further, the aperture of control gate for convenience, described door is an overhead door 21, correspondingly, is formed with the negative pressure channel leading portion that is communicated in described operation room by described air hole at described housing bottom, the better air curtain of easier like this formation protectiveness.The negative pressure channel leading portion mainly is meant the part that is positioned at housing bottom here.
Form the quality of air curtain in order to improve, the width of part on gate width direction that closes on door at least of described negative pressure channel leading portion equals the width of operation room, and is provided with a plurality of air holes on this direction uniformly.
For better control test effect, this detector also comprises control system, this control system is included in the vibration transducer 18 that is provided with on the marble slab 16 of described testing equipment, the display that is used to show the Vib. vibration frequency that is connected in this vibration transducer output terminal, and being arranged at the regulating device that being used on the compressed gas source pipeline 13 regulate compression gas flow and pressure, the adjusting by gas flow and pressure makes Vib. obtain suitable vibration frequency.Simultaneously, can flowmeter, operation valve, pressure-detecting device be set at the compressed gas source pipeline and carry out obtaining of correlation parameter.
Further, described control system also comprises the pick-up unit that is used to detect the Vib. amplitude, and output is shown to described display.According to check, if only consider frequency, often test effect is difficult to control, find that through long-term observation the amplitude of Vib. is the key factor of influence resistance dry state microorganism penetrability, for this reason, this programme is introduced amplitude detecting device, thereby provides reference for the adjustment by source of the gas.
Preferably, in order to improve the controllability of detector, described compressed gas source is a compressibility, this compressibility comprises air compressor 10 and is connected to the gas-holder 9 of this air compressor exhausr port, this gas-holder picks out described compressed gas source pipeline, thereby, can output pressure and the pressure gas of stability of flow.
Be connected to tensimeter on the described gas-holder, so that observe the pressure in the gas-holder whether reach predetermined value intuitively.
