Abstract
The utility model discloses a filter paper accurately-conveying device of an atmospheric particulate matter PM10 concentration online monitor, which is characterized by comprising a conveying rod (3), two idler wheels (2) vertically connected to the same side of the conveying rod (3), and a linear sliding rail (4), wherein the linear sliding rail (4) is connected with the inner side of the conveying rod (3). The filter paper accurately-conveying device can be used for straightening and flattening soft strip-shaped filter paper to ensure that the straightened and flattened strip-shaped filter paper can synchronously move together with the conveying rod within an effective stroke; because a bearing is arranged in an end wheel, no relative sliding exists between the filter paper and the end wheel, the filter paper bears a little resistance when leftwards entering with a certain distance; and because the linear sliding rail is selected, the conveying rod bears a very little resistance and is balanced without run out when leftwards and rightwards moving. Therefore, according to the filter paper accurately-conveying device, the stability and the reliability of apparatus operation are improved.
Description
Technical field
The utility model relates to Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper conveyer.
Background technology
The concentration of Atmospheric particulates PM10 is that the prefectures and cities of China national Environmental Protection Agency (EPA) regulation must survey one of factor, so occur various PM10 on-line monitoring appearance on the market.Known Atmospheric particulates PM10 concentration on-line monitoring appearance is as shown in Figure 1, and it is according to Beta-ray principle of absorption, above filter paper, places a β source, below filter paper, places a detector, to survey the intensity after the β ray passes filter paper.Its concrete measuring process is; With the blank filter paper of appointment be placed on P1 point measurement between β source and the detector through blank filter paper Beta-ray intensity level and preserve; Bleed sampling and on filter paper, stay dust spot of the P2 point that filter paper that then should the zone moves on to another appointment; The filter paper that will contain dust spot after the sampling again is moved back into the P1 point between β source and the detector; Measure its Beta-ray intensity level again and preserve, and the data that record for twice are performed mathematical calculations, thereby obtain concentration dependent data with PM10 through CPU.After accomplishing this circulation, filter paper then left the fixing distance of shift-in one repeat a process again.
Accurate, straight and move to the P2 point reposefully in order to realize from the P1 point with the filter paper of softness; Accurate, straight and move to the P1 point reposefully from the P2 point again; Except needs push away reel and with the control sections such as control motor, pressure roller, light barrier and photo interrupter of its direct connection, also need one special with filter paper filter paper conveyer stretching and that switch back and forth at P1 point and P2 point place exactly.
The utility model content
The purpose of the utility model just provide a kind of can accuracy good, the Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper conveyer of high, the good reliability of stability.
The technical scheme that the utility model adopts is: the accurate conveyer of Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper; It is characterized in that it comprises driven rod, is vertically connected on two rollers and the line slide rail of driven rod homonymy, described line slide rail and driven rod fixedly connected to the inner side.
The wheel of said roller is actively connected in the rotating shaft of roller through bearing.
It is spacing to wheel that the rotating shaft wheel inboard of said roller is connected with axle sleeve.
The utility model beneficial effect is: because filter paper is when the roller through both sides, the utility model can be stretching with the banded filter paper of softness, even up, and it can be moved in effective stroke inter-sync with driven rod; Owing in the end wheel bearing has been installed, filter paper and end wheel do not have slip relatively, and when certain distance was advanced on a left side, resistance was very little; Owing to selected line slideway for use, during the driven rod move left and right, its resistance is very little, and balance, nothing are beated.Therefore the utility model has improved the stability and the reliability of instrument operation.

Embodiment
Like Fig. 2, shown in Figure 3, the accurate conveyer of Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper, it comprises driven rod 3, be vertically connected on two rollers 2 and the line slide rail 4 of driven rod 3 homonymies, described line slide rail 4 fixedly connected to the inner side with driven rod 3.The wheel of roller 2 is actively connected in the rotating shaft of roller through bearing.It is spacing to wheel that the rotating shaft wheel inboard of roller 2 is connected with axle sleeve.
The utility model is installed on the Atmospheric particulates PM10 concentration on-line monitoring appearance, and as shown in Figure 1,1 among the figure is the filter paper conveyer, and filter paper is through two rollers 2, because the spacing of two rollers is certain, and therefore can tensioning filter paper.Little so the side-to-side movement freely of the friction force of line slide rail.
Claims (3)
1. the accurate conveyer of Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper; It is characterized in that it comprises driven rod (3), is vertically connected on two rollers (2) and the line slide rail (4) of driven rod (3) homonymy, described line slide rail (4) fixedly connected to the inner side with driven rod (3).
2. the accurate conveyer of Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper according to claim 1 is characterized in that the wheel of said roller (2) is actively connected in the rotating shaft of roller through bearing.
3. the accurate conveyer of Atmospheric particulates PM10 concentration on-line monitoring appearance filter paper according to claim 1 and 2, it is spacing to wheel that the rotating shaft wheel inboard that it is characterized in that said roller (2) is connected with axle sleeve.
