Description
Technical field
The utility model relates to storage equipment field, particularly a kind of dust measuring filter membrane storage system.
Background technology
Dust measuring filter membrane is the main use consumptive material of dust concentration measuring in air of workplace.In air of workplace, dust determination adopts existing occupational health standard method, principle utilizes air sampling pump to extract the dust laden air of certain volume, dust detention, on the filter membrane of known quality, by increment and the gas production of filter membrane after sampling, is calculated to the concentration of dust in unit volume air.Main operational steps comprises filter membrane preparation (be dried, destatic, weigh, record, number), sampling, Sample storage (getting film, preservation, transportation), sample weighing (be dried, destatic, record), result calculating.The subject matter existing in real work: 1. filter membrane consumption large (not easy care), 1 the power plant's evaluation of Occupational Hazard Control Effect of take is example, measuring front filter preparation quantity should be at 300～500, if year totals a plurality of projects, filter membrane numbering is more chaotic, is difficult to guarantee its uniqueness, simultaneously because filter membrane quantity is too many, after sampling, can not sort out in order and deposit, be difficult to meet quality control or the requirement of occupational health detection technique; 2. before and after sampling, filter membrane need be used 100,000/electronic analytical balance to weigh, before sampling, weigh complete dry, destatic etc. after step, general data is comparatively reliable, but it is more to weigh disturbing factor after sampling, present stage common practices be that filter membrane after adopting dirt is carried out to doubling or three foldings, be then placed in clean plastic bag, taking back laboratory weighs, while there is again following problem A, on-the-spot doubling or three foldings in this process, dust easily comes off, if speckle with on hand ash, and easy contaminated samples; B, while placing from plastic bag, the film of doubling or three foldings easily scatters automatically, causes dirt to come off in plastic bag; After C, sampling, filter membrane must be dried, destatic rear weighing equally, and this step exists the above two kinds of situations of dust releasing phenomenon all can cause Lower result equally, even occurs after sampling weighing value before weighing value is lower than sampling.
In sum, how to realize before and after sampling dust measuring filter membrane in order, neat, sort out and preserve, after how avoiding sampling dust measuring filter membrane preserve, dust releasing in transportation, the process such as dry, be the problem that the art emphasis faces.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of dust measuring filter membrane storage system is provided.This programme can solve filter membrane in prior art and deposit classification confusion, and the caducous problem of dust.
The utility model adopts following technical proposals:
A dust measuring filter membrane storage system, comprises box body, also comprises for depositing the storage bag of filter membrane; Described box body inside is provided with a plurality of rectangular openings, and the bottom surface of box body is a gas-permeable nets; The inwall of rectangular opening is fixedly connected with cord, and the other end of this cord is positioned at box body outside and is fixedly connected with drop, is carved with numbering on drop; Described storage bag is arranged in rectangular opening and cord is pressed on gas-permeable nets; Bottom described box body, four jiaos are connected with base by recoil spring.
Preferably, described storage bag is template material.
Preferably, described box body is provided with lid.
Preferably, on described lid, establish paperboard film is installed, install in film and establish paperboard.
Principle of work of the present utility model and process:
Before and after sampling, filter membrane is dried, weighs, transports, preserves with storage bag is integrated.During filter membrane access, first filter membrane is packed in storage bag and sealed, storage bag open end upwards presses cord to put into rectangular opening, drop is exposed to rectangular opening outside, when needs take out filter membrane, only need find the drop of corresponding numbering, hand take drop and on carry, storage bag bottom upward movement in cord holder, and then storage bag is taken out of.When filter membrane is dried, whole box body is put into rectangle dryer, open each storage bag sealing, box body bottom gas-permeable nets guarantees its permeability to air, and in dryer, after airtight certain hour, filter membrane fully can be dried.When filter membrane weighs, filter membrane is together positioned over electronic analytical balance with storage bag and weighs, without film is taken out.In filter membrane transportation, box body bottom installing recoil spring, avoids causing dust releasing because of box body vibrations as far as possible.
The beneficial effect that the utility model compared with prior art had is:
1, establish storage bag, adopt filter membrane with the mode of the integrated weighing of storage bag, can solve the problems such as dust releasing of spot sampling because existing in filter membrane doubling or three folding processes.
2, box body is established rectangular opening and drop, realizes filter membrane (or storage bag) and deposits in batches, is carved with numbering on drop, guarantees that sample is orderly, neat, sorts out and preserve.
3, the mode that adopts cord that drop is connected with rectangular opening, pulls cord can easily take out sample, simple and easy applicable.
4, gas-permeable nets is established in box body bottom, is positioned over dryer internal medicine and realizes dry in batches.
5, box body installing recoil spring, can avoid the impact of vibration on filter membrane in storing unit transportation.
Accompanying drawing explanation:
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
