Protrusion 7 is set on pressure sensor 101, and pressure sensor 101 is electrically connected with processing module.When in use, first sky is leaked
Bucket 1 is placed on pressure sensor 101, and processing module records current value, turns to sealing plate 52 seal up opening later
The position in portion 2 can install slurry additional, be packed into after proper amount of slurry i.e. openable sealing plate 52, flow out slurry, and trigger meter
When device 10 start timing, etc. stream of slurry it is complete, the numerical value that pressure sensor 101 senses with record numerical value it is consistent when (in view of complete
A possibility that consistent lower, settable certain error range), processing module 300 drives timer 10 to stop timing.
In another embodiment, with reference to Fig. 7, metering module 100 include more guide posts 102 being set on frame body 200,
The support spring 103 and position sensor 104 being sheathed in every guide post 102,102 quantity of guide post can have more,
Usually it is advisable with four, is uniformly looped around around funnel 1.The convex block 8 being sheathed in guide post 102 is provided on loophole 1,
Funnel 1 can be moved up and down along guide post 102.The support spring 103 being set in guide post 102 offsets with convex block 8, support
Firmly funnel 1.Position sensor 104 is fixed on frame body 200, can be optoelectronic switch or travel switch etc., the present embodiment
It is middle to use travel switch, plectrum 9 is provided on funnel 1, for stirring travel switch.In use, empty funnel 1 is placed first
In in guide post 102, it can arrange that travel switch is (initial when recording funnel 1 without slurry in 9 corresponding position of plectrum at this time
Position), sealing plate 52 is turned to the position for sealing up opening portion 2, slurry can be installed additional, since the support of sealing plate 52 is made
With excessive displacement will not occur downwards for funnel 1 at this time, be openable sealing plate 52 after being packed into proper amount of slurry, make to starch
Stream goes out and triggering timing device 10 starts self-clocking, and 1 lower part of funnel loses the support of sealing plate 52 to compress support bullet
Spring 103, i.e. funnel 1 will decline, and can slowly rise with slurry outflow, weight saving, and funnel 1 rises to initially after streamer
Position, plectrum 9 stir travel switch, and travel switch sends signal to processing module 300, so that timer 10 stops timing.
This fluidity tester is in use, first install funnel 1 to metering device 100, later by starter 50
Sealing plate 52 seal up 1 lower part of funnel；Then to suitable position slurry is uniformly perfused, until slurry upper surface in adjustment gauge 4
With 4 lower contacts of gauge；The sealing plate of starter 50 is opened later, is started at this point, processing module 300 controls timer 10
Timing；After device 100 to be batched senses that stream of slurry is complete, processing module 300 controls timer 10 and stops timing.Staff can
Pulp flow degree is calculated by the time that timer 10 is shown.
The present invention includes at least following advantage：
1. fluidity tester self-clocking in on-test of the invention, and stop timing after stream of slurry is complete, from
Dynamicization degree is high, manually controls timer unlatching without people and stops, improving the accuracy of convenience and test result；
2. the sealing plate of fluidity tester of the invention is opened and sealing funnel is very convenient, and close by rubber compounding
Envelope, leakproofness are strong；
3. fluidity tester of the invention is not necessarily to valve, it is not easy to plug, has used the sealing plate of plate, it is easy to clean.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Those skilled in the art can understand the contents of the present invention and implements accordingly, and protection of the invention can not be limited with this
Range.Any equivalent change or modification in accordance with the spirit of the invention should be covered by the protection scope of the present invention.
