Abstract
The utility model relates to a fixed-height shock-free efflux powder repose angle measuring device which is characterized by comprising a measuring box (1) and an angle measuring ruler (2); the measuring box (1) is a rectangular solid and has a smooth inner surface, above which an opening is cut; the angle measuring ruler (2) takes a shape of a quadrant and is arranged on the facade of the measuring box (1); the scale marked on the angle measuring ruler (2) is the degree of the repose angle; the 0 graduation line on the angle measuring ruler (2) coincides with a vertical line at one side of the facade of the measuring box (1); and the 90 graduation line on the angle measuring ruler (2) coincides with a horizontal line at the vertical facade of the measuring box (1). The measuring device is applicable to the fluidity measurement of compact or loosened powder, requires a small quantity of samples, has small measurement error, convenient operations and applications, simple structure and can read out the degree of the repose angle directly, thus being economical and practical.
Description
Technical field
The utility model relates to a kind of powder angle of repose measuring appliance, it is characterized in that it is a kind of fixed high mobile measuring appliance of the outflow of impact formula powder that do not have.
Background technology
The angle of repose of powder (repose ang1e) is meant that powder grain material is at the cone surface of surface level accumulation formation and the angle between the surface level, claim angle of static friction or stocking angle again, be an indirect measurement index of powder tackness, relevant with the size of shot particle, shape, humidity, orientation etc.The material that the angle of repose is big more, internal friction are big more, and the ability of being scattered is more little.The powder of good fluidity, its angle of repose is less.Generally speaking, the angle of repose of powder is during less than 30 °, and is better mobile, during greater than 40 °, mobile relatively poor.
The method of measuring the angle of repose has multiple, used measuring appliance is also inequality, with differing greatly that a kind of measuring appliance is measured sometimes, " surfactant for example, the measurement at powder and particle angle of repose " (standard GB 11986-89) regulation the fixed funnel genealogy of law one glass funnel is vertically fixed on suitable height, with powder from funnel, flow out be piled into coniform, the angle of repose of powder is the hypotenuse of circular cone and the angle on plane, also can be by measuring the height and the radius calculation angle of repose of cone, this measuring appliance is because the height difference of funnel device, powder is also different from the impulsive force size that eminence falls, and causes differing greatly of angle of repose measurement.
Generally speaking, the angle of repose of no impact force measurements than the result that impact force measurements is arranged more greatly, but the error that operation factors causes is less, reappearance is better.
Except that the angle of repose measuring appliance of national Specification, be divided into sliding, outflow property, rollability three classes at loose type powder angle of repose measuring principle commonly used at present, angle of repose measuring appliance according to the sliding principle design has tubular type, box, ramp type tilts, angle of repose measuring appliance according to outflow property principle design has column-hole type, angle of repose measuring appliance according to the rollability principle design has drum-type, the suitable measurement good fluidity of above measuring appliance, the powder angle of repose that quality is big, but the error of operation is bigger.
The principle of measuring tight type powder angle of repose foundation is an impact, and measuring appliance has funneling and box, and these measuring appliances are better to the adaptability of powder, operate miss is less, but measurement is bigger with sample size, can not directly read the angle of repose, must use inconvenient by calculating.
Summary of the invention
At the defective that existing powder angle of repose measuring appliance exists, the utility model reach by the following technical solutions measure that powder angle of repose amount of samples is few, error is little, can directly read the angle of repose, purpose easy and simple to handle.
Consult accompanying drawing, a kind of fixed high outflow of impact formula powder angle of repose measuring appliance that do not have comprises measure case 1 and angulation scale 2, and angulation scale 2 is installed in the side of measure case 1.
The accompanying drawings the technical solution of the utility model, a kind of fixed high outflow of impact formula powder angle of repose measuring appliance that do not have, comprise measure case 1 and angulation scale 2, measure case 1 is the rectangular parallelepiped of the smooth and top opening of inside surface, angulation scale 2 is the fan-shaped measure case 1 that is installed in of 90 degree and faces face, the scale of mark is the number of degrees at angle of repose on the angulation scale 2,0 scale on the angulation scale 2 is faced facade one side perpendicular line with measure case 1 and is overlapped, and 90 scale marks on the angulation scale 2 are faced facade upper end horizontal line with measure case 1 and overlapped.
Concrete using method is: measure case 1 is placed horizontal position (as shown in Figure 1), get a certain amount of powder and add in the measure case 1, slowly inclination measurement case 1 makes it be vertical position (as shown in Figure 2), reads the angle of powder inclined-plane on angulation scale 3, promptly.
Compare with existing powder angle of repose measuring appliance, the beneficial effects of the utility model are: reduce by 70% sample size, measuring error can directly read the angle of repose less than 1%, operation and easy to use, simple in structure, economical and practical.
Description of drawings
Shown Fig. 1, Fig. 2 and Fig. 3 are respectively fixed high the do not have horizontal position of measuring appliance, the outflow of impact formula powder angle of repose front elevation, vertical position front elevation and rear views, and wherein 1 is measure case, the 2nd, and the angulation scale.
Embodiment
The embodiment of accompanying drawings technical solutions of the utility model, a kind of fixed high outflow of impact formula powder angle of repose measuring appliance that do not have, comprise measure case 1 and angulation scale 2, measure case 1 is the rectangular parallelepiped of the smooth and top opening of inside surface, angulation scale 2 is the fan-shaped measure case 1 that is installed in of 90 degree and faces face, the scale of mark is the number of degrees at angle of repose on the angulation scale 2,0 scale on the angulation scale 2 is faced facade one side perpendicular line with measure case 1 and is overlapped, and 90 scale marks on the angulation scale 2 are faced facade upper end horizontal line with measure case 1 and overlapped.
Claims (1)
