Description
Technical field
The present invention relates to a kind of pulping proving installation of calming the anger of simulating different material level.
Background technology
Utilizing tailings to carry out in the preparation process of filling slurry as compaction material, in order to ensure the homogeneity of last mortar, usually need carry out pulping concentration to it and flow rate effects is checked, putting sand concentration to reach raising, reduce plugging probability and evenly put the object of sand.
Generally, in order to observe the pulping situation of last mortar, adopting naked eyes sense organ to carry out subjective judgement sometimes, needing observer to have very rich experience like this, even if rich experiences person, sometimes also accurate estimation can be difficult to because the mine tailing character of various places varies.In addition, sometimes also can under bulk container condition, carry out larger test to test the pulping effect of last mortar, water in last mortar is subject to gases at high pressure and drives among small sand storehouse, reach the Pneumatic-hydraulic interlocked object stirred, make last mortar be issued to desirable pulping state in set pressure.There is following defect in these class methods: experimental scale is large, and test unit is complicated, and complex operation, takes time and effort, and manufacturing cost and material cost are all higher, easily causes material waste or causes safety problem.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiency of above-mentioned background technology, and provide a kind of structure simple, cost is low, easy and simple to handle, the safe and reliable pulping proving installation of calming the anger of simulating different material level.
The technical scheme that the present invention solves the employing of its technical matters is that a kind of pulping proving installation of calming the anger of simulating different material level, comprises small sand storehouse, the tapered structure in bottom in described small sand storehouse, forms sand storehouse centrum; The top in described small sand storehouse is provided with sealing pressing upper cover, and the top in described small sand storehouse is also provided with gas admittance valve, pressure test table, pressure maintaining valve and enters sand valve; The side of described sand storehouse centrum is provided with mud making spray nozzle of calming the anger, and the bottom of described sand storehouse centrum is provided with puts sandpipe, puts sandpipe and is provided with and puts sand valve, densimeter, flowmeter.
Further, put described on sandpipe and be also provided with recoil water valve.
Further, the volume in described small sand storehouse is 2 ~ 5m
3.
Compared with prior art, advantage of the present invention is as follows:
(1) top, small sand storehouse is provided with gas admittance valve, pressure test table, pressure maintaining valve, pressurizes according to the slurry level of required simulation, and to reach set pressure, the slip can simulating different material level is calmed the anger pulping; Small sand is put sandpipe and is provided with densimeter, flowmeter, and put densimeter in sand process and can detect and put sand concentration, flowmeter can detect puts sand flow amount, thus can detect the effect of pulping of calming the anger.Structure of the present invention is simple, and can carry out the test of small-scale simulation pulping, easy and simple to handle, manufacturing cost is with the cost of material is low, and material utilizes fully, and handling safety is reliable.
(2) put sandpipe and be provided with recoil water valve, passing into of the recoil controlled water processed of water valve, by logical for the tailings punching of piling up bottom the centrum of sand storehouse, prevent tailings from being blocked by sand storehouse centrum.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1-gas admittance valve, 2-pressure test table, 3-pressure maintaining valve, 4-enter sand valve, 5-small sand storehouse, 6-sand storehouse centrum, 7-recoil water valve, 8-put sand valve, 9-put sandpipe, 10-densimeter, 11-flowmeter, 12-put sandpipe mouth, 13-mud making spray nozzle of calming the anger, 14-sealing pressing upper cover.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, the present embodiment comprises small sand storehouse 5, and the volume in small sand storehouse 5 is 3m
3; The tapered structure in bottom in small sand storehouse 5, forms sand storehouse centrum 6; The top in small sand storehouse 5 is provided with sealing pressing upper cover 14, and the top in small sand storehouse 5 is also provided with gas admittance valve 1, pressure test table 2, pressure maintaining valve 3 and enters sand valve 4; The side of sand storehouse centrum 6 is provided with mud making spray nozzle 13 of calming the anger, and the bottom of sand storehouse centrum 6 is provided with puts sandpipe 9, puts sandpipe 9 and is provided with recoil water valve 7, puts sand valve 8, densimeter 10, flowmeter 11.
Gas admittance valve 1 is for controlling passing into of gas; Pressure test table 2 is for testing the pressure in small sand storehouse 5; Pressure maintaining valve 3, for exhaust, makes the pressure in small sand storehouse 5 reach typical set value.
During use, open into sand valve 4, last mortar is passed into small sand storehouse 5, tailings sedimentation after a period of time deposited by mortar, the tailings sedimentation at its centrum 6 position, medium sand storehouse is the most closely knit, and pressure is maximum.The sealing pressing upper cover 14 at top, small sand storehouse 5 is built, and with fastening bolt, sealing pressing upper cover 14 is fixed.Pressurized air enters top, small sand storehouse 5 from what open for airduct gas admittance valve 1, the pressure produced according to different depth slip converses the pressure that required simulation air pressure produces last mortar liquid level, pressurize according to the slurry level of required simulation during test, to reach set pressure; The mud making spray nozzle 13 of calming the anger opening sand storehouse centrum 6 carries out calming the anger pulping, after pulping is even, open recoil water valve 7, after the tailings punching of piling up bottom sand storehouse centrum 6 being led to a small amount of water, close recoil water valve 7 immediately, sand valve 8 is put in unlatching, last mortar flows out from putting sandpipe 9, put densimeter 10 in sand process can detect and put sand concentration, flowmeter 11 can detect puts sand flow amount, thus the effect of pulping of calming the anger can be detected, flowing into tailings pond by detecting rear last mortar from putting sandpipe mouth 12, last mortar output flow state can be observed thus simultaneously.This process completes the detection to last mortar concentration and flow, to reach the real-time detection to pulping effect.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these amendments and modification are within the scope of the claims in the present invention and equivalent technologies thereof, then these revise and modification also within protection scope of the present invention.
The prior art that the content do not described in detail in instructions is known to the skilled person.
