After the structure is adopted, the electronic scale can weigh to-be-measured particle powder with set weight; the seconds counter is used for calculating the time for the to-be-measured particle powder to flow through the mobility device; the mobility of the to-be-measured particle powder can be judged intuitively and accurately by utilizing the flowing time of the to-be-measured particle powder flowing through a fixed device; and the device is simple to operate, and can measure repeatedly.
Description
Technical field
The present invention relates to a kind of particle powder verifying attachment, particularly a kind of for measuring the device of particle powder mobility.
Background technology
Mobility is an important performance indexes of particle powder.Powder granule size evenly, without powder, good fluidity.Therefore for evaluating mobility, have and adopt the distribution of particles of particle tested powder to differentiate mobility.But distribution of particles is only a principal element that affects mobility, and mobility is also subject to the impact of the factors such as gel content, water cut and hollow ball of particle powder, therefore the method that adopts distribution of particles to evaluate, not accurate enough, fiduciary level is not high, and test loaded down with trivial details, poor repeatability.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide a kind of test accurate, simple to operate, reproducible for measuring the device of particle powder mobility.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of for measuring the device of particle powder mobility, comprise electronic scale, stopwatch and flow device, this flow device comprises base and is fixed on the measurement support on base, on this measurement support, be fixedly connected with and be useful on the taper cone barrel that holds particle powder to be measured, this taper cone barrel bottom is turbination, the center is provided with the circular hole of known diameter, is provided with the receiver corresponding with circular hole on described base.
Described taper cone barrel bottom is provided with the catch of circular hole described in rotatable shutoff.
Distance between described circular hole and base is 20cm.
The tapering of described taper cone barrel bottom turbination part is 60 degree.
The present invention adopts after said structure, use above-mentioned electronic scale can take the particle powder to be measured of setting weight, flow device can make particle powder to be measured therefrom flow through, stopwatch is for calculating the time that particle powder to be measured flows through, with particle powder to be measured, flow through the time of one stationary installation-flow device, can judge intuitively, exactly the mobility of particle powder to be measured, simple to operate, can duplicate measurements.
Accompanying drawing explanation
Fig. 1 is that the present invention is a kind of for measuring the structural representation of the device of particle powder mobility.
Wherein have: 1. base; 2. measure support; 3. taper cone barrel; 4. circular hole; 5. catch; 6. receiver.(in figure, α is the tapering of taper cone barrel bottom turbination part).
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 1, a kind of for measuring the device of particle powder mobility, comprise electronic scale, stopwatch and flow device, this flow device comprises base 1 and is fixed on the measurement support 2 on base 1, on this measurement support 2, be fixedly connected with and be useful on the taper cone barrel 3 that holds particle powder to be measured, these taper cone barrel 3 bottoms are turbination, and the center is provided with the circular hole 4 of known diameter, are provided with the receiver corresponding with circular hole 46 on described base 1.
Described taper cone barrel 3 bottoms are provided with the catch 5 of circular hole 4 described in rotatable shutoff.
Distance between described circular hole 4 and base 1 is 20cm.The portable while, makes the flowing time of particle powder relatively long, makes to pull open certain gap between mobility certified products and unacceptable product, makes test result more accurate.
The tapering α of described taper cone barrel 3 bottom turbination parts is 60 degree.This tapering can facilitate particle powder to be measured from taper cone barrel 3, to flow out fast.
During use, with electronic scale, take the particle powder to be measured of setting weight, generally need be greater than 50g, catch 5 rotates and blocks circular hole 4 or directly block circular hole 4 with hand, after load weighted particle powder to be measured is poured in taper cone barrel 3, after catch 5 is removed or is unclamped the hand of blocking circular hole 4 from circular hole 4, stopwatch starts timing, and in taper cone barrel 3, particle powder to be measured all flows out to after receiver 6, and stopwatch stops timing, stopwatch displaying time is the flow velocity of particle powder to be measured, is also mobility data.
