Technical field
The utility model relates to dust measurement equipment, especially a kind ofly is used to measure, the repeatedly sampler of the dust appearance of sampling channel unification.
Background technology
Dust is that one of human health threatens greatly, and the content of dust is directly connected to people's health in the surrounding environment.Especially in the more inferior special places of mine, if can not monitor, with the generation that directly causes staff's occupational illness to the Dust Capacity in the environment; The main method of present domestic measurement dust has weight method and laser method, and wherein laser method has following shortcoming: need do contrast to traditional weight method when 1) measuring and correct complex operation; 2) laser can receive the influence of the factors such as form, size, smooth finish, color on chemical property, the grit surface of dust, causes measurement result inaccurate; 3) its range is fixed, and is not suitable for the monitoring in circumstance complication place.The major equipment that weight method adopts is a direct-reading dust appearance, and traditional direct-reading dust appearance mostly comprises a sample tap and a measuring port, before each sampling filter membrane clip is put into measuring port earlier and surveys original Dust Capacity; Then filter membrane clip is taken out the insertion sample tap, by regulation requirement sampling, the sampling back is inserted measuring port at the taking-up filter membrane clip and is measured sampling back Dust Capacity; Calculate Dust Capacity through twice measurement difference.Therefore above-mentioned traditional type dust appearance will inevitably cause the disappearance or the increase of dust on the filter membrane clip owing to need the repeated moving filter membrane clip, causes the inaccurate of measurement result.Continuous development along with the dust appearance; The direct-reading dust appearance that a kind of measuring port and sample tap adopt same passage has appearred in the market; So just do not need the repeated moving filter membrane clip, avoided Dust Capacity irregular change on the filter membrane clip, improved the measuring accuracy of dust appearance; But be not difficult to find out above-mentioned dust appearance necessary filter membrane clip of changing after carrying out one-shot measurement; And owing to the reason of dust appearance self structure; The replacing of filter membrane clip is very inconvenience, and this has directly increased staff's labor capacity, has also influenced the work efficiency of dust appearance simultaneously.
Summary of the invention
The purpose of the utility model is to provide a kind of and is used to measure, the repeatedly sampler of the dust appearance of sampling channel unification, to solve existing direct-reading dust appearance owing to changing the low problem of work efficiency that filter membrane clip causes repeatedly.
In order to address the above problem; The repeatedly sampler of the utility model adopts following technical scheme: a kind ofly be used to measure, the repeatedly sampler of the dust appearance of sampling channel unification; Comprise and be used to rotate the filter membrane spool of assembling filter membrane volume and be used for the draw-gear that filter membrane winds off volume; Have between described filter membrane spool and the draw-gear and be used to supply filter membrane to wind off the exhibition film stroke of volume; Said exhibition film stroke is provided with the film pressing device that is used to compress filter membrane, and described film pressing device comprises orienting sleeve, and said orienting sleeve internal fixation is provided with electromagnet sleeve; Slidable fit is useful on the gland that compresses filter membrane between the outside wall surface of electromagnet sleeve and the internal face of orienting sleeve; Gland is inhaled to release with described electromagnet sleeve and is cooperated, and is top-loaded with back-moving spring between gland and the said orienting sleeve, has the air hole that connects said gland, electromagnet sleeve and orienting sleeve on the film pressing device.
Said gland turns edge in having away from an end of said back-moving spring.
Said orienting sleeve is fixedly connected with fixed mount away from an end of said gland, has the through hole that connects with the axially extending bore of said orienting sleeve on the fixed mount.
Described draw-gear comprises the stranding film wheel that is used for the rubbing filter membrane, and described stranding film wheel is connected with drive unit.
Described drive unit is a stepper motor, and drive unit is in transmission connection through synchronous belt and said stranding film wheel.
Because the form that the repeatedly sampler of the utility model adopts film pressing device, filter membrane spool and draw-gear to combine; Can on said filter membrane spool, rotate assembling filter membrane volume in the use; The gland of die arrangement is movable under the effect of electromagnet sleeve and back-moving spring, with this filter membrane is compacted to the measuring port place of dust appearance or unclamps filter membrane, and is movable and when unclamping filter membrane when gland; Affect filter membrane to stretch through draw-gear; Change the filter membrane section corresponding with this, adopt a repeatedly sampling of filter membrane volume under the condition that need not open dust appearance replacing filter membrane sheet, improved the work efficiency of dust appearance thereby be implemented in the measuring port of dust appearance.
Further, in described gland is provided with away from an end of back-moving spring, turn edge, can increase the sealing surface of gland, further strengthen the sealing effectiveness of gland; Reduce the interference of the gas beyond the gas passage, improved the measuring accuracy of dust appearance; Fixed mount is used for the repeatedly sampler of the utility model is fixed in the correspondence position of dust appearance; Rub the film wheel with the hands and can timely used filter membrane be rubbed the dust appearance, the filter membrane that avoided the use of occupies the inner space of dust appearance; Drive unit adopts stepper motor, can combine with electromagnet sleeve, sets the frequency of operation and the duration of electromagnet sleeve, and the working time that combines with electromagnet sleeve then to set stepper motor is set the uncoiling length of filter membrane, thereby realizes the automatically working of dust appearance.
