Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
Fig. 1 is the structural representation of measurement apparatus of the present invention, as it is shown in figure 1, include Glass rod 1, the end
Seat 2, the pillar 3 being arranged on described base 2 side and the fixing bar 4 being arranged on described pillar 3,
Described base 2 is provided with power supply 5 and controls switch 6；The upper surface of described base 2 is provided with water-coal-slurry to be held
Device 7, the sealing part of described water-coal-slurry container 7 is provided with sealing-plug 8；Away from described on described fixing bar 4
One end of pillar 3 is provided with the solenoid 9 being connected with described power supply 5, outside described solenoid 9
Be provided with in week rotation sucker 10, described rotation sucker be provided with some sizes different for inhaling the most described glass
The circular groove 11 of rod 1.In the present embodiment, described base 2 is additionally provided with the timer 14 being connected and shows
Display screen 15, described Glass rod 1 is provided with velocity sensor 16, the outfan of described velocity sensor 16
It is connected with described timer 14；Shaking device 17, described shaking device it is additionally provided with on described base 2
17 underfaces being arranged on described water-coal-slurry container 7.In the present embodiment, described Glass rod 1 is with scale
And described Glass rod top is equipped with rustless steel cap；Described water-coal-slurry container is with scale.The present embodiment is permissible
Use and measure insertion depth by scale and obtain whereabouts insertion time two ways to water by timer
Stability of coal slurry measures, when using scale to measure insertion depth, after controlling switch open, with electricity
The solenoid energising that source is connected, described rotation sucker can produce bigger suction, and rotate sucker
Circumferentially position be provided with some circular grooves, various sizes of Glass rod can be inhaled solid at described circular groove
In.When, after the power supply controlling switch closedown solenoid, Glass rod with a scale falls due to action of gravity
Inserting in the water-coal-slurry of water-coal-slurry container, water-coal-slurry precipitation Glass rod scale indicated by upper surface is soft
Precipitate height, water-coal-slurry precipitation water-coal-slurry container scale indicated by upper surface deducts soft precipitation height and is
The difference of hard-caked sediment height, the liquid level upper level of water-coal-slurry container graduation indication and liquid level lower surface height
It is water-coal-slurry bleed liquid level.Measure by the way of timer obtains the whereabouts insertion time when using
During water coal slurry stability, detected the whereabouts of described Glass rod by the velocity sensor being arranged on Glass rod
Speed and stop speed, timer thus obtain falling speed described in the fall time of described Glass rod and under
Time that falls all in described display screen display, such that it is able to judge the stability of described water-coal-slurry；And use
Water coal slurry stability is judged by two ways, it is judged that result is more accurate, loses when a kind of mode simultaneously
During effect, also another way can continue measure judge stability.The most described water-coal-slurry lower vessel portion
It is provided with shaking device, described water-coal-slurry can be shaken, after having shaken, PH can be used
The pH value of described water-coal-slurry accurately measured by meter, it is thus achieved that more accurate measurement result.

Executing in example, on described fixing bar 4, the one end away from described pillar is provided with rotating shaft 13, described solenoid 9
Being set in described rotating shaft 13, described rotation sucker 10 is connected with described rotating shaft 13, described rotation
Sucker can be followed described rotating shaft and be rotated together, and the suitable circular groove of size so can be facilitated to be in suitable position
Put, in order to select corresponding Glass rod to test, thus different in water-coal-slurry container described in replication
The stability of position water-coal-slurry, in order to obtain measurement result more accurately.
The present invention improves accuracy and the intuitive of water coal slurry stability judge process, and water-coal-slurry container
Open top is relatively big, and water-coal-slurry is easily put into and is difficult to be attached to chamber wall, affects stability observing；With
Time ensure that Glass rod vertical drop and be not required to manually throw Glass rod, it is to avoid water-coal-slurry is difficult to load
Long narrow test tube, and water-coal-slurry is easily attached to test tube wall and is difficult to the shortcoming observed；The present invention uses timing
Device and velocity sensor, Negotiation speed sensor detects the falling speed of described Glass rod and stops speed
Degree, timer thus obtain the fall time of described Glass rod, such that it is able to judge the steady of described water-coal-slurry
Qualitative；The most described water-coal-slurry lower vessel portion is provided with shaking device, can shake described water-coal-slurry
Dynamic, after having shaken, PH meter can be used accurately to measure the pH value of described water-coal-slurry；Present configuration
Simply, easy to operate, judge process simple and fast and intuitively accurate, it is highly suitable for laboratory and carries out water
It is widely used in stability of coal slurry and pH value test.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention
