Description
Technical field
The present invention relates to a kind of experiment storehouse, especially the combined type of mask filtration efficiency Performance Detection is detachably tested the storehouse.
Background technology
Mouth mask is often to use in people's life and work or even necessary article, when for example eqpidemic disease (influenza, SARS etc.) is popular, when the workman is operated in the dust atmosphere etc.Its quality and end user's healthy direct relation, so its quality is even more important.The quality of mouth mask depends primarily on its filtration efficiency function, so the filtration efficiency Performance Detection of mouth mask is very important.This requirement must have certain space to supply testing crew in this space, to accomplish specified action to do filtration efficiency and detect, and is the staff in the action simulation real work dynamically such as running.So it is necessary to design an experiment storehouse of satisfying above-mentioned functions.Existing pick-up unit function singleness; Structure is a monoblock type, inconvenient disassembled for transport; Air inlet and outlet device is simple, and particulate gas concentration difference is big in the storehouse, and testing result is unreliable.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of prior art: provide a kind of mask filtration efficiency that can carry out to detect; Detachable, transportation cost hangs down is convenient to the transportation installation; Particulate gas is tested the storehouse uniformly in the storehouse.
For realizing above-mentioned purpose, technical scheme provided by the invention is following: construct a kind of combined type special type protection mask filtration efficiency Performance Detection experiment storehouse, comprise the main storehouse of detecting, detect and prepare storehouse, particulate gas generating system, the circulation system, exhaust system, detection system.
Said main detection storehouse is the rectangular body plate construction of combined type, comprises the air inlet storehouse from top to bottom, detects storehouse (branch top and the bottom), exhaust storehouse (subsidiary treadmill pedestal function).Link to each other through T shape link respectively between each warehouse and between the detection warehouse top and the bottom, all there is T shape link in front, the left surface and the back side; The right side connects the slit and inserts rubber weather strip.T shape link comprises T shape frame, set bolt, elastic sealing gasket.Detection right side, storehouse has one can be equipped with sealing strip to the door of outside unlatching around the door.The air inlet storehouse is 2 bin structures, and top drilling links to each other with the particulate gas generating system, and intermediate membrane is uniformly distributed with 9 circular holes, and base plate is uniformly distributed with 18 circular holes.Detect warehouse four sides, top, storehouse glass window all is housed, use rubber weather strip in the middle of glass and the sheet material; The front has 2 circular holes and is used for the joint detection system; The lower left side bottom has a circular hole and is used to insert a power board, seals with O-ring seal between circular hole and lead.The exhaust storehouse is one " recessed " type bin, and recessed part can be put into a treadmill, height such as bossing and running machine running band, and convex top is got 5 holes, and bottom, bin left side is made a call to a circular hole and is linked to each other with the circulation system.
It is little because of volume that the storehouse is prepared in said detection, adopts monolithic construction to get final product.The left side is the standard-sized sheet mouth, is connected with detection right side, storehouse through T shape link.The right side is equipped with one can be equipped with sealing strip to the door of outside unlatching around the door, on the door glass window is housed, the middle rubber weather strip that uses of glass and sheet material.The storehouse top left side has a rectangular opening, and air-supply arrangement is housed.
Said particulate gas generating system is by air strainer, and U.S. TSI 9306A aerosol generator is formed.
The said circulation system connects an ebullator by bottom, left side, exhaust storehouse circular hole and a flowmeter is formed.Circulation system outlet is connected to the opening at top, air inlet storehouse.
Said exhaust system connects a flowmeter by bottom, left side, exhaust cabin circular hole, and exsiccator absorbs the pond and forms.
Said detection system is divided two-way two circular apertures of joint detection storehouse top front face respectively, comprises photometer, filtrator and sampling pump.
The beneficial effect in the combined type special type protection mask filtration efficiency Performance Detection experiment storehouse that the present invention narrates is: make the experiment storehouse can not only carry out static mask filtration efficiency through the design of adding treadmill and detect, also can carry out the mask filtration efficiency detection of dynamic; Design through the tectonic association formula makes originally because of putting into treadmill and becomes big experiment storehouse and had detachablely, and transportation cost hangs down the characteristics of being convenient to transport installation; T shape coupling arrangement through design can reach good connection fixed effect and sealing; 2 bins in air inlet storehouse and dividing plate perforation structure have enough buffering diffusion time and constraint by particulate gas; Particulate gas can evenly be got into detect the storehouse; Add the porous design in exhaust storehouse, can optimize particulate gas, improve accuracy of detection at the distribution consistency degree that detects the storehouse; The adding of the circulation system can be practiced thrift the gas making raw material; Exhaust system can effectively be handled waste gas, avoids polluting.The use of common experiment storehouse can also be used as in this experiment storehouse after treadmill is moved away from simultaneously.
