Abstract
The utility model relates to a kind of dust and to descend slowly and lightly measurement mechanism, it is characterized in that: it comprises base (1), the top of described base (1) is fixed with a perpendicular support (2), described perpendicular support (2) is connected with dust collection funnel (8) and measuring tube (7), the bottom of described dust collection funnel (8) puts in the top of measuring tube (7), the bottom of described measuring tube (7) is fixed on base (1), the inwall of this measuring tube (7) is carved with from top to bottom many read text scale lines (9).This dust measurement mechanism that descends slowly and lightly is formulation and the enforcement of the plant maintenance standard in all kinds of place, provides quantitative basis.There is this measurement mechanism, can avoid crossing maintenance to equipment and increasing maintenance cost in plant maintenance, avoided owing safeguard and endanger equipment safety operation.
Description
Technical field
The utility model relates to a kind of measurement mechanism, and especially a kind of dust descends slowly and lightly measurement mechanism.
Background technology
In industrial processes, usually can produce a large amount of dusts.Scatter aerial dust, a part is siphoned away by cleaner and removes, and a part can descend slowly and lightly everywhere, works the mischief to the normal operation of production equipment in the region that descends slowly and lightly.Work the mischief to equipment operation to eliminate and reducing dust, the thickness that usually will descend slowly and lightly according to dust formulates plant maintenance standard, regularly carries out cleaning to the dust descended slowly and lightly on equipment and safeguards.But in real work, the thickness that but cannot descend slowly and lightly to dust carries out accurate quantification description.
In our enterprise, there are high-tension electricity air chamber, transformer room, low tension air chamber, computer room.The ability that different equipment anti-dust is polluted is had nothing in common with each other, as high-tension electricity air chamber, the dust that equipment descends slowly and lightly does not allow more than 1mm, and computer room does not allow more than 0.5mm, reach this thickness and just must carry out cleaning dedusting maintenance to equipment, otherwise will the safe operation of equipment be affected.But in real work, lack the ways and means that the dust amount of descending slowly and lightly is measured, the quantitative criteria that the cleaning dedusting being just difficult to formulation equipment is safeguarded, or have quantitative criteria to be also difficult to Measurement accuracy in force.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of dust to descend slowly and lightly measurement mechanism, and this dust measurement mechanism that descends slowly and lightly is formulation and the enforcement of the plant maintenance standard in all kinds of place, provides quantitative basis.There is this measurement mechanism, can avoid crossing maintenance to equipment and increasing maintenance cost in plant maintenance, avoided owing safeguard and endanger equipment safety operation.
The purpose of this utility model is achieved in that
The utility model dust descends slowly and lightly measurement mechanism, comprise base, the top of described base is fixed with a perpendicular support, the sidewall of described perpendicular support is fixed with lateral frame and lower lateral frame, the end of described upper lateral frame is connected with upper set collar, the end of lower lateral frame is connected with lower set collar, the diameter of fixed ring is greater than the diameter of lower set collar, in fixed ring, cover has dust collection funnel, in described lower set collar, cover has measuring tube, the bottom of described dust collection funnel puts in the top of measuring tube, the bottom of described measuring tube is fixed on base, the inwall of this measuring tube is carved with from top to bottom many read text scale lines.
Described measuring tube is transparent pipe.
Compared with prior art, the descend slowly and lightly beneficial effect of measurement mechanism of this dust is:
The measuring principle of this measurement mechanism adopts volume principle, the dust that the large disc of dust collection funnel is collected, load in the measuring tube of little disc, in a disguised form the thickness of dust is amplified, be convenient to accurate reading, the data read convert through equal-volume, are dust and descend slowly and lightly thickness.This measurement mechanism is formulation and the enforcement of the plant maintenance standard in all kinds of place, provides quantitative basis.There is this measurement mechanism, can avoid during plant maintenance increasing maintenance cost, avoided owing safeguard and endanger equipment, ensure that the safe operation of equipment.
Accompanying drawing explanation
Fig. 1 is that the utility model dust descends slowly and lightly the structural representation of measurement mechanism.
Wherein: base 1, perpendicular support 2, upper lateral frame 3, lower lateral frame 4, upper set collar 5, lower set collar 6, measuring tube 7, dust collection funnel 8, read text scale line 9.
Embodiment
See Fig. 1, the utility model relates to a kind of dust and to descend slowly and lightly measurement mechanism, comprise base 1, the top of described base 1 is fixed with a perpendicular support 2, the sidewall of described perpendicular support 2 is fixed with lateral frame 3 and lower lateral frame 4, the end of described upper lateral frame 3 is connected with upper set collar 5, the end of lower lateral frame 4 is connected with lower set collar 6, the diameter of fixed ring 5 is greater than the diameter of lower set collar 6, in fixed ring 5, cover has dust collection funnel 8, in described lower set collar 6, cover has measuring tube 7, described measuring tube 7 is transparent pipe, the bottom of described dust collection funnel 8 puts in the top of measuring tube 7, the bottom of described measuring tube 7 is fixed on base 1, the inwall of this measuring tube 7 is carved with from top to bottom many read text scale lines 9.
The measuring principle of this device is, first this device is placed on measurement point, dust through a time is collected, and dust is loaded in the measuring tube of little disc from the dust that the large disc of collection funnel is collected, and adopts volume principle, in a disguised form the thickness of dust is amplified, be convenient to accurate reading, look squarely measuring tube subsequently, read the groove number of degrees residing for dust end face, the data read convert through equal-volume, can converse dust and to descend slowly and lightly thickness.
Concrete equal-volume conversion relation is:
Dust thickness=measuring tube number of degrees/(dust collection funnel diameter/measuring tube internal diameter)
2.
A descend slowly and lightly embodiment of measurement mechanism of this dust is as follows:
The back cut diameter of dust collection funnel is 100mm, and the internal diameter of measuring tube is 10mm.Measuring tube is every 5mm down scale line from inner bottom surface, and every 10mm makees high range line, successively upwards.
Because conversion relation is: dust thickness=measuring tube number of degrees/(dust collection funnel diameter/measuring tube internal diameter)
2.
Like this, when the number of division of measuring tube is at 50mm, just can show that the dust thickness that descends slowly and lightly is 0.5mm.
If without this measurement device, directly estimating dust thickness, is that 0.4mm or 0.5mm cannot differentiate.
Claims (2)
