Abstract
The utility model relates to a portable and adjustable device for measuring angle of repose, which aims to be suitable for wide range of size fraction of raw materials and adjustable material falling height. The device comprises a material discharge funnel, a movable rubber sleeve, a circular material receiving platform and a bracket, wherein the bracket comprises a support platform and a four-leg rack; a plurality of holes are formed on each leg of the four-leg rack; pins used for adjusting material falling height are inserted into the holes; a hole is formed at the center of the support platform; the material discharge funnel takes the shape of a cone and is plated in the central hole of the support platform; the movable rubber sleeve is the lining of the material discharge funnel and is fixedly placed on the inner side of the funnel; the size of the movable rubber sleeve is matched with that of the material discharge funnel; and the circular material receiving platform is mounted on the four-leg rack under the support platform through pins.
Description
Affiliated technical field
The utility model relates to a kind of solid accumulation form pick-up unit.
Background technology
Angle of repose also is called stocking angle, belongs to the basic physics parameter, be material under stacking states, the angle of inclined-plane and surface level.Angle of repose determine to help understanding the grown form of material in banking process, for example in the shaft furnace charging process, analyze all kinds of materials behind the blast furnace of packing into, the grown form in stove; Stock yard is expected the height of bar when carrying out solid accumulation, thus measuring and calculating memory space or the like.Can only be to detect raw materials used angle of repose at present randomly, the data of surveying can only relatively not have versatility, the repeatability and the repeatability of measurement result are relatively poor.
Summary of the invention
The utility model purpose is the deficiency that overcomes above-mentioned prior art, and a kind of portable adjustable angle of repose determinator that the grain size of raw material scope is wide, blanking is Height Adjustable that adapts to is provided.
The utility model comprises blanking funnel, active rubber sleeve, circular material receiving and support; Support comprises support platform and four foot rests, all has a plurality of holes on four supporting legs of four foot rests, is installed with the pin that is used to adjust the blanking height on the hole; Support platform central authorities are porose, and blanking funnel is a cone shape, are placed in the medium pore of support platform; The active rubber sleeve is the liner of blanking funnel, and its size and blanking funnel are supporting, fixedly is placed on the funnel inboard; Circular material receiving is installed on four foot rests below the support platform by pin.Circular material receiving is used for blanking is piled into cone, is convenient to measure the angle of repose of material.The active rubber sleeve can prevent from also can avoid material to fall deviation in driction hopper centre measuring the strong material of fragility direct and steel funnel collision generation crushing phenomenon in dropping process.
At the onesize rubber lining in circular material receiving upper berth, make a circular apron with sheet iron or TR thin rubber skin around the circular material receiving, influence its accumulation effect to prevent that material from flashing.
It is big that the utility model can be measured material grade scope, and by making bigger funnel discharging bore and corresponding material receiving, material grade measurement range and mensuration content (as the accumulation simulation of blast furnace burden structure) can further be extended, and can satisfy the demand of iron and steel metallurgical industry to the material base characteristic research.The blanking height is convenient adjustable.This covering device adopts material receiving adjustable height and blanking funnel outlet adjustable height dual regulation way, and control method is simple.This device is completely detachable, conveniently this device being placed directly in material scene or any three meters square places measures, to reduce the obstacle in handling process, alleviate remote sampling and manpower and materials consumption such as the labour intensity of measuring the back sample that finishes is big greatly, and can shorten minute greatly.Can satisfy the fast measuring of different material size fractionated angle of repose, for Ferrous Metallurgy material base performance study provides data accurately and reliably.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, blanking funnel, 2, the active rubber sleeve, 3, medium pore, 4, support platform, 5, circular material receiving, 6, pin, 7, four foot rest supporting legs, 8, blanking.
Embodiment
For the angle of repose that satisfies the size fractionated material is measured two blanking funnels 1 and two supporting active rubber sleeves 2 that designed size is different.Big funnel height 350mm, feeding mouth diameter 250mm, discharging opening diameter 150mm.Little funnel height 200mm, feeding mouth diameter 150mm, discharging opening diameter 40mm.When measuring the big grade material of 40～130mm, use big blanking funnel; When measuring 0～30mm granule stage material, use little blanking funnel.For mensuration and easy to carry is installed, blanking funnel 1 usefulness iron sheet is made.
When filling with substance usefulness charging scoop from evenly spreading all around, avoids human factor to cause the segregation of material above blanking funnel 1.Should take a sample according to relevant criterion, guarantee the rationality of material sampling and measure accuracy.After blanking 8 is cone on the circular material receiving 5, take circular apron away, measure the solid accumulation height and pile up diameter, try to achieve the angle of repose α of this material by the trigonometric function relational expression:
In the formula: R is the solid accumulation radius, and H is the solid accumulation height.
Claims (2)
