Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of granula dust measuring instrument of automatically controlling, as shown in Fig. 3 to Fig. 7, comprise sample collection case 31 and be positioned at the casing cover cap 39 on sample collection case 31, on casing cover cap 39, be wholely set commissioning pipe 32, the side of sample collection case 31 is provided with circular open (not shown), on circular open, be provided with filtrator (not shown), in filtrator, be provided with support filter screen, and filtrator is connected with flowmeter 33 and vacuum pump 34 in turn by flexible pipe, wherein, on the control circuit of vacuum pump 34, be connected with the micro computer timing display controller 35 for close vacuum pump in the time that the schedule time arrives, on micro computer timing display controller 35, be connected with and trigger its switch 36 that starts timing, switch 36 is positioned at the top of described commissioning pipe 32.
In the time carrying out granular formulations dust determination, before pouring sample into, vacuum pump 34 is in running order, for making the required air velocity of the interior maintenance of sample collection case 31, in pouring sample into, user of service's Push switch 36, because switch 36 is positioned at the top of commissioning pipe 32, so user of service can operate easily, thereby trigger micro computer timing display controller 35 and start timing, on simultaneously micro computer timing display controller 35, demonstrate the time (reverse countdown or countdown all can) of timing, like this, user of service can adjust the speed of falling sample according to the time demonstrating, and in the time that the schedule time arranging arrives, micro computer timing display controller 35 can cut out vacuum pump 34 automatically, synchronize and carry out with timing, pass pump thereby the utility model can ensure down sample, and people complete operation easily in the utility model, easy and simple to handle.
For convenience of operation, switch 36 is preferably microswitch.And be that for example, micro computer timing display controller 35 can also be connected with output indicator 355 and/or prompt tone hummer 356 to some promptings of operating personnel (stipulated time is about to arrive, and need fall as early as possible sample etc.).Meanwhile, micro computer timing display controller 35 can also be connected with operation keyboard 352, so that it is carried out to some settings.
In the time carrying out circuit design, micro computer timing display controller 35 in the utility model can be designed as the structure shown in Fig. 4, wherein, 358 is the control chip of micro computer timing display controller 35, clocking capability is triggered by microswitch 357, and display section 351 can be 8 LED charactrons, and operation keyboard 352 can be 5 bit manipulation keyboards, power supply 353 can directly adopt 220V alternating current, closes vacuum pump 34 and can adopt the mode of relay output 354 to control.
In prior art, also there is such problem: sample need to evenly be poured in certain hour (60 seconds), normally hand-held beaker is directly poured in commissioning pipe 32 at present, the bad control of speed of sample, and sample often slides along the tube wall of commissioning pipe 32, if the tube wall of commissioning pipe 32 is smooth not, be difficult to ensure the accuracy of measurement result.For addressing this problem, in the utility model, the upper end of commissioning pipe 32 has additional stemless funnel 37, for not affecting the air velocity in sample collection case 31, between stemless funnel 37 and commissioning pipe 32, be provided with septal branch support arrangement 38, and for ensureing the height of sample free-falling, the lower port of stemless funnel 37 flushes with the upper port of commissioning pipe 31.
When use, sample is poured in stemless funnel 37, sample falls into commissioning pipe 32 along stemless funnel 37, due to the existence of stemless funnel 37, can be easy to the pouring volume of Quality control and pour speed into, and because the lower port of stemless funnel 37 is positioned at commissioning pipe 32 middle parts, so the situation of having avoided sample to slide along the tube wall of commissioning pipe 32, sample is all directly from commissioning pipe 32 middle part free-fallings, thereby guaranteed the accuracy of measurement result.
In the utility model, those skilled in the art can be designed to various version by septal branch support arrangement 38 according to general knowledge, septal branch support arrangement 38 can be both integrative-structure with stemless funnel 37, can be also Split type structure, exemplified 3 kinds of specific constructive form below and described:
(1) as shown in Figure 5, septal branch support arrangement 38 is structure as a whole with stemless funnel 37, septal branch support arrangement 38 is arranged on the back-up block 381 of stemless funnel 37 outside surfaces, back-up block 381 is preferably at least two, back-up block 381 both can be supported on commissioning pipe 32 upper port inner sides, also can be supported on commissioning pipe 32 upper port edges;
(2) as shown in Figure 6, septal branch support arrangement 38 is Split type structure with stemless funnel 37, septal branch support arrangement 38 comprises support ring 382 and is positioned at the feet 383 of support ring 382 bottoms, same, feet 383 both can be supported on commissioning pipe 32 upper port inner sides, also can be supported on commissioning pipe 32 upper port edges;
(3) as shown in Figure 7, septal branch support arrangement 38 is Split type structure with stemless funnel 37, septal branch support arrangement 38 comprises support ring 384, lower support ring 385, connecting link 386 between upper support ring 384 and lower support ring 385 and is positioned at the auricle 387 of lower support ring bottom, preferably switch 36 is microswitch, and microswitch is resisted against the below of auricle 387.Now, septal branch support arrangement 38 is erected at by connecting link 386 on the edge of commissioning pipe 32 upper port, under this version, the time of the falling sample sample poured out vibrations that septal branch support arrangement 38 is produced, or the vibrations that stemless funnel 37/ septal branch support arrangement 38 produces are touched in the time of falling sample have gentle hands, or auricle is touched in have gentle hands can trigger microswitch, thereby micro computer timing display controller 35 is started working.
At present, granular formulations is generally divided into two kinds of circular granular agent and bar shaped granules, for circular granular agent, the diameter of the lower port of the stemless funnel 37 in preferred the utility model adapts with the diameter of granular formulations to be poured into, the light (hourglass principle) so that a certain amount of granular formulations freely falls at the appointed time.Like this, for the circular granular agent of different-diameter, the stemless funnel 37 that can select lower port diameter to match, thereby can disposable sample to be poured into all be poured in stemless funnel 37, sample is (60 seconds) interior light that freely falls at the appointed time, pour speed into without control, convenient accurate.
In the utility model, stemless funnel 37 can adopt various smoothnesss better and the less material of Electrostatic Absorption is made, preferably adopt glass to make, because the existing good smoothness of glass, Electrostatic Absorption is relatively little, and its transparency can person easy to use be observed the process of falling sample, thereby the speed of falling sample of adjustment.The material of septal branch support arrangement 38 is not limit, and those skilled in the art can select as required flexibly.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
