According to filling slurry bleeding rate ζ, rate η that shrinks concept, bleeding rate is to secrete effluent characteristics to account for water among filling slurry The percentage ratio of gross mass;The rate of shrinking is that filling slurry volume change accounts for the percentage ratio of filling slurry cumulative volume after solidification.For For goaf filling, bleeding and the rate of shrinking are practical physical indexs, and relevant problem also has realistic meaning.Casting resin The rate of shrinking of slurry is another practical physical quantity closely-related with bleeding rate, and it is that unit volume filling slurry ultimately forms and fills Fill out the percentage ratio shared by reduction in volume after body, be usually used in adding up the actual of goaf and fill amount of fill, little the filling of the rate that generally shrinks Extender paste has and preferably connects top effect and shrink phenomenon owing to filling slurry exists, and must estimate discharging according to practical situation during filling The rate that shrinks of slurry, in order to contemplate charging quantity more than needed in actual filling, so that the obturator of consolidation can fill mined out Behind district, periphery ore deposit rock is played effective supporting role.
Prior art is to use open-top receptacle to test, but the most measured parameter can be because of the water among filling slurry Dividing evaporation to be affected, its test data are the most accurate.The most domestic have some free bleedings of manufacturer production concrete mortar Rate and free swell test instrument, but workmen is after injecting slurry test, in addition it is also necessary to use the instrument such as ribbon or ruler Carry out measurement result, waste time and energy, it is contemplated that provide a kind of equipment to solve this problem.
Summary of the invention
In order to solve the problems of the prior art, this utility model provides a kind of obturator slip bleeding rate and the rate that shrinks Test device.
This utility model provides a kind of obturator slip bleeding rate and the test device of rate of shrinking, including pallet, tank, Slurry vessel, glass container, water pipe, slip pipe and moisturizing tubule are used for carrying liquid.Water pipe is provided with water valve and dispensing water valve, It is provided with below tank and slurry vessel on moisturizing tubule and slip pipe, moisturizing tubule and slip pipe and is respectively equipped with moisturizing water valve and slip Valve;Being provided with glass container below moisturizing tubule and slip pipe, glass container is arranged over pressure relief vent, and right side connects bleeding pipe, secretes Being provided with inductive rod in water pipe, the lower end, sideline of four vertical directions of glass container is provided with telescopic shaft;Microcomputer overall control valve leaves Close and calculate.
Further, described glass container inwall level altitude is provided with induction apparatus, and described induction apparatus and microcomputer pass through line Road connects.
Further, described relief port switchs by microcomputer control, and during on-test, release is once, afterwards every three hours Release once, each release one minute.
Further, it is respectively equipped with effusion meter at described moisturizing water valve and slurry valve.
The beneficial effects of the utility model are: converted filling slurry volume change by rate of water make-up, the slip recorded Volume change is more accurately and device uses small test tube to collect to secrete water outlet, obtain to secrete effluent characteristics more accurate;Glass holds The lifting of device base can regulate the size of obturator test block, to meet the requirement of different tests;
Microcomputer controls slip, water and pressure relief vent valve switch, time-consuming and labor intensity.

Fig. 2 is the structural representation of bleeding pipe.
Detailed description of the invention
This utility model is further illustrated by explanation and detailed description of the invention below in conjunction with the accompanying drawings.
Drawing reference numeral in Fig. 1 is: 1. tank 2. slurry vessel 3. water pipe 4. water valve 5-1. dispensing water valve 5-2. moisturizing water valve 5-3. slurry valve 6. moisturizing tubule 7. slip pipe 8. pressure relief vent 9. induction apparatus 10. bleeding valve 11. bleeding pipe 12. inductive rod 13. is filled Fill out body 14. and secrete water outlet 15. microcomputer 16. telescopic shaft 17. glass container 18. pallet.
Drawing reference numeral in Fig. 2 is: 10. bleeding valve 11. bleeding pipe 12. inductive rod.
As it is shown in figure 1, a kind of obturator slip bleeding rate and the test device of the rate that shrinks, including pallet 18, described pallet 18 are provided with tank 1, slurry vessel 2, glass container 17, water pipe 3, slip pipe 2 and moisturizing tubule 6.Described water pipe 3 is provided with water Valve 4 and dispensing water valve 5-1, be provided with moisturizing tubule 6 and slip pipe 7 below described tank 1 and described slurry vessel 2, described moisturizing is thin It is respectively equipped with moisturizing water valve 5-2 and slurry valve 5-3 on pipe 6 and described slip pipe 7;Described moisturizing tubule 6 and described slip pipe 7 times Side is provided with described glass container 17, and the lower end, sideline of described 17 4 vertical directions of glass container is provided with telescopic shaft 16, described glass Glass container 17 is arranged over pressure relief vent 8, and described glass container 17 side connects bleeding pipe 11, is provided with sensing in described bleeding pipe 11 Rod 12;Microcomputer 15 is connected with valve by circuit, described microcomputer 15 overall control valve switch and calculating.
This utility model implements to measure obturator slip bleeding rate and the rate of shrinking comprises the following steps:
(1) first, pour the obturator raw material (such as cement, tailings etc.) weighing up ratio into slurry vessel, microcomputer inputs In obturator raw material, the proportional quantity M of water, opens water valve, and water flows through water pipe and starts water filling in tank and slurry vessel, treats slurry vessel When interior water reaches preset blending ratio amount, microcomputer automatic control closes dispensing water valve.When tank stores a certain amount of water, manual-lock Slip is also stirred until homogeneous by water valve, simultaneously regulation glass container substructure height, by the volumetric void fraction of container to preset value.
(2) controlling microcomputer and open slurry valve, slip enters container from slurry vessel along slip pipe flow, treats that slip reaches predetermined height When spending, sensor is by incoming for signal microcomputer, and microcomputer controls to cut out slurry valve, and slip stops flowing downward, and microcomputer controls to beat simultaneously Opening relief port, now the volume at the glass container following slurry of inner sensor horizontal plane is exactly filling slurry cumulative volume V.
(3) observe slip to be filled reach final set formed obturator entity time, control microcomputer open bleeding valve, secrete water outlet from Flow in container in bleeding pipe.After stopping flowing, quality m of water outlet secreted by microcomputer in obtaining bleeding pipe by inductive rod.
(4) microcomputer record secrete effluent characteristics m after automatically open up moisturizing water valve, start to glass container water filling, microcomputer leads to Inflow-rate of water turbine meter record rate of water make-up, when liquid level reaches predetermined altitude, sensor is again by incoming for signal microcomputer, and microcomputer controls to cut out Moisturizing water valve, water retention only flows downward.The rate of water make-up of microcomputer record is exactly filling slurry volume change v.
(5) microcomputer according to measured filling slurry cumulative volume V, secrete quality m of water outlet, filling slurry volume change v And the content M of the water in slip proportioning calculates bleeding rate and the rate that shrinks, formula is as follows:
Bleeding rate: ζ=m/M*100%
Shrink rate: η=v/V*100%.
