Description
Technical field
The utility model relates to a kind of granule materials device for measuring angle of repose under water.
Background technology
At compaction material experimental determination granule materials under water when angle of repose, existing apparatus structure is comparatively simple, sometimes also there is no moulding pattern, generally, just funnel bracket, funnel, one flat plate, basin, are the simple combination of ruler.When test first by granule materials by being positioned over funnel natural packing on funnel bracket on one flat plate, become a centrum shape, then slowly the centrum shape material on flat board is put into the basin that fills clear water, after granule materials is met water, angle of internal friction changes, angle of dump slope also changes, soak saturated completely Deng bank, angle of dump slope stablize constant after, the radius of circle scattering with ruler mensuration particle stockpile, measure again piling height, then to the business of piling height and the radius of circle tangent value of negating, thereby obtain granule materials angle of repose parameter under water.There is following defect in said structure: (1), by water-immersed granule materials process, material usually can scatter and form irregular shape, and the radius parameter error gathering is thus larger, the result accuracy, the less reliable that calculate; (2) operator must read granule materials piling height, radius parameter from water surface top, has the error causing because of overwater refraction, affects test accuracy; (3) trouble of operation, reappearance is lower, cleaning inconvenience.
Utility model content
The purpose of this utility model is overcome the above-mentioned deficiency of prior art and a kind of granule materials device for measuring angle of repose is under water provided, adopt this device to measure granule materials angle of repose under water, easy and simple to handle, the radius, the height parameter error that gather are little, and can avoid the reading error causing because of refraction, result accuracy, the reliability measured are high, and cleaning is convenient.
The technical solution of the utility model is: a kind of granule materials device for measuring angle of repose under water, on work top, be fixed with a support bar, post upper is vertical with funnel bracket one end to be socketed and to fix by tightening knob, and the other end of described funnel bracket is fixed with funnel; On the worktable facing below hopper centre, be provided with locating slot, in locating slot, place a transparent Flat bottom container, in transparent Flat bottom container, be placed with a platform.
In the bottom of described transparent Flat bottom container, one side is provided with a freeing port, and described freeing port is connected with drainpipe, and wash-out valve is housed on drainpipe.
Described locating slot is circular locating slot, and described transparent Flat bottom container is drum-shaped, and described platform is round platform; The center of circle of described circular locating slot, the transparent Flat bottom container of drum-shaped, round platform and funnel remains on same perpendicular line.
The slightly larger in diameter of described circular locating slot is in the diameter of the transparent Flat bottom container of drum-shaped.
The below of described worktable is provided with leveling serew, and level meter is installed on worktable.
The utility model compared with prior art has following features: (1) round platform upper bottom surface radius is the radius of particle stockpile under water, and the radius parameter error of collection is little; (2) operator can look squarely and read granule materials piling height, can avoid overlooking the reading error causing because of refraction in reading, and result accuracy and the reliability of mensuration are high; , (3) are easy and simple to handle, and easily, reappearance is strong in cleaning; (4) simple in structure, easy to process, cost is low.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is made and being further described.
Embodiment:
With reference to accompanying drawing: the present embodiment is provided with leveling serew 8 below worktable 7, and the top of worktable 7 is provided with level meter 9.Above work top, be fixed with a support bar 6, post upper is vertical with funnel bracket 4 one end to be socketed, also to fix by tightening knob 5, and the other end of described funnel bracket is fixed with funnel 3 by tightening knob 2; On the worktable facing below hopper centre, be provided with circular locating slot 10, place a transparent Flat bottom container 15 of drum-shaped in locating slot, the slightly larger in diameter of circular locating slot is in the diameter of the transparent Flat bottom container 15 of drum-shaped.In transparent Flat bottom container, be placed with a round platform 11.Keep the center of circle of circular locating slot, the transparent Flat bottom container of drum-shaped, round platform and funnel to overlap.
Be carved with scale mark 12 at the sidewall of transparent Flat bottom container; Be provided with a drainpipe 16 in its bottom one side, wash-out valve 17 is housed on drainpipe.
Principle of work of the present utility model and using method are: first adjust leveling serew 8 according to level meter 9, to the complete level of upper surface of worktable 7.Then, transparent Flat bottom container 15 is placed in circular locating slot, makes the bottom surface circle of transparent Flat bottom container 15 concentric with circular locating slot 10, then round platform 11 is put into transparent Flat bottom container 15, make equally round platform 11 and above-mentioned two circles keep concentric.To guarantee that bell mouth 1 is right against the round platform 11 upper bottom surface centers of circle, guarantee follow-uply to add bank 13 that material forms for conical.Slowly pack clear water into transparent Flat bottom container 15, the height that exceeds round platform 11 to the clear water water surface 14 approximates round platform 11 bottom surface radiuses, stops adding water.Regulate the position of funnel bracket 4 on support bar 6 by funnel bracket tightening knob 5, make funnel 3 be in a suitable height, keep bell mouth 1 higher than the clear water water surface 14, but need approach the clear water water surface 14 as far as possible.Granule materials is slowly added to funnel 3, and material is concentrated and is evenly fallen into the water after bell mouth 1 water conservancy diversion from funnel 3, sinks on round platform 11.Along with increasing of material, formation stockpile 13 gradually, continues reinforcedly, and in the time observing the material of bank 13 peripheries and fall showed increased along round platform 11 peripheries, exponent stockpile 13 piles with completely in round platform, continues reinforcedly still can drop, and now stops feeding in raw material.Wait for peacefully a bit of time, after bank 13 complete stabilities, look squarely the height and the bank 13 top height that read and record round platform 11.The height of bank 13 top height and round platform 11 is subtracted each other, obtain the height of bank 13, the business of the height to bank 13 and the round platform 11 upper bottom surface radius of circles tangent value of negating, this arc-tangent value is the angle of repose under water of granule materials.After being completed, wash-out valve 17 is opened, material flows into pollution discharge pond or blowdown container along freeing port 16 and drainpipe 18 under the washing away of water, and after flushing, whole test process finishes.
