Abstract
The utility model relates to a fixed high impact efflux powder particle repose angle measurer which includes a container box, a measuring box, an angle measuring staff guage and a rotary shaft; the container box and the measuring box are cuboids the inner surfaces of which are smooth and the upper sides of which are opened; the container box is connected with the measuring box through the rotary shaft; the angle measuring staff guage is arranged on the orthophoria angle of the measuring box; the scale marked on the angle measuring staff guage is the degree of the repose angle; the zero scale line on the angle measuring staff guage is parallel with the horizontal axle wire of the section of the rotary shaft and is coincident with the vertical line of the orthophoria elevation of the measuring box. The fixed high impact efflux powder particle repose angle measurer uses less samples, is small in measuring error, can directly read the degree of the repose angle, is conveniently operated and used, is simple in structure, is economic and practical and is suitable for detecting compact or loosing efflux powder particles.
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 mobile measuring appliance of HI high impact outflow formula powder of deciding.
Background technology
The angle of repose of powder (repose angle) 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.
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 ofly decide HI high impact and flow out formula powder angle of repose measuring appliance, comprise container case 1, measure case 2, angulation scale 3 and rotating shaft 4, container case 1 is connected with measure case 2 by rotating shaft 4, and angulation scale 3 is installed in the side of measure case 2.
Concrete using method is: open measuring appliance, make container case 1 and measure case 2 be in parallel position, get a certain amount of powder and add in the container case 1, slowly tilt container case 1 makes itself and measure case 2 vertical coincidences, powder flows in the measure case 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 60% 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 and Fig. 2 decide HI high impact to flow out formula powder angle of repose measuring appliance elevation cross-sectional view and back pseudosection, and wherein 1 is container case, and the 2nd, measure case, the 3rd, angulation scale, the 4th, rotating shaft.
Embodiment
The embodiment of accompanying drawings technical solutions of the utility model, a kind ofly decide HI high impact and flow out formula powder angle of repose measuring appliance, comprise container case 1, measure case 2, angulation scale 3 and rotating shaft 4, container case 1 and measure case 2 are rectangular parallelepipeds of the smooth and top opening of inside surface, container case 1 is connected with measure case 2 by rotating shaft 4, angulation scale 3 is the fan-shaped measure case 2 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 3,0 scale on the angulation scale 3 is parallel with rotating shaft 4 section horizontal median axis and face the bottom surface horizontal line with measure case 2 and overlap, and 90 scale marks on the angulation scale 3 are vertical with rotating shaft 4 section horizontal median axis and face the facade perpendicular line with measure case 2 and overlap.
