Description
Technical field
The present invention relates to a kind of efficiently automatic disintegration pulp classifier of soft rock slaking test, particularly relate to a kind of disintegration tester of meeting the water disintegration for field soft rocks such as highway, railways.Especially meet the efficient automatic sieving disintegration tester of the soft rock slaking test of water disintegration, the disintegration of carbonaceous soft rock local highway roadbed filling chance water for carbonaceous soft rock side slope top layer under the condition of raining, can reflect effectively really the distribution situation of grain composition after the soft rock disintegration, provide foundation for carrying out follow-up physical and mechanical experiment.The invention still further relates to the test method of this soft rock disintegration automatic sieving instrument.
Background technology
The soft rock disintegration refers to after soft rock is met water a series of physics, chemical change occur, and makes soft rock be become a kind of phenomenon of different-grain diameter size by integral body.
To inevitably pass the area of soft rock rich content in increasing highway, the railway construction process, utilizing soft rock is inevitable as the filling material of roadbed.Because soft rock is met the characteristic of water disintegration, often causes following problem: meet the resistance to overturning reduction that water can make roadbed with the roadbed that soft rock fills, even the phenomenon that roadbed subsidence occurs, cave in.Soft Rock Slope is met water and also can be caused whole slope stability to reduce, the phenomenon on appearance landslide etc.So the disintegration properties of research soft rock has great meaning to the from now on transport development of Soft Rock Area.
The test method of existing traditional soft rockfall solution test is first carbonaceous soft rock to be carried out independent disintegration, then sieves, and again carbonaceous soft rock is mixed again after having sieved and carries out disintegration, again screening after disintegration a period of time.The result that will at every turn sieve like this compares, and changes very littlely within the quite a long time such as the fruit granule rank, illustrates that disintegration stops substantially.
The shortcoming of above test mainly is disintegrating procedue and screening process are separately carried out, can make the process of the test complicated, in addition, being also that the time that disintegration is stopped substantially can't being made timely judges, can prolong test period, also be to sieve the number of times that carries out more, can make the mass loss of sample also larger, thereby can affect the precision of test.Therefore, a kind of i.e. efficient again accurate carbonaceous soft rock disintegration, screen experiments instrument of design substitutes traditional screen experiments and is necessary.
Summary of the invention
First technical matters to be solved by this invention provides a kind of disintegrating procedue and screening process carries out simultaneously and efficiently, accurately and the soft rock disintegration automatic sieving instrument of being convenient to observe.
Second technical matters to be solved by this invention provides the test method of this soft rock disintegration automatic sieving instrument.
In order to solve above-mentioned the first technical matters, soft rock disintegration automatic sieving instrument provided by the invention, be provided with transparent urceolus at shaking table, eminence at described transparent urceolus is provided with water inlet pipe, lower at described transparent urceolus is provided with rising pipe, be placed with successively from top to bottom a plurality of transparent inner cores in the described transparent urceolus, the bottom of each described transparent inner core is equipped with the screening hole, and the aperture in the screening hole of a plurality of described transparent inner cores from top to bottom reduces to arrange according to the laboratory standard size of mesh successively.
The internal diameter of a plurality of described transparent inner cores from top to bottom increases successively, be provided with the inner core holder in each described transparent inner core, the described transparent inner core that the previous stage internal diameter is less can be put into the described transparent inner core of the larger rear one-level of internal diameter and be supported by described inner core holder.
The upper end of a plurality of described transparent inner cores flushes with the upper end of described transparent urceolus, and is provided with the stator regulated that is between described transparent inner core and the described transparent urceolus in the upper end of a plurality of described transparent inner cores.
The described screening hole of described transparent inner core is followed successively by from top to bottom: 60mm, 20mm, 5mm, 1mm, 0.25mm and 0.075mm.
Described shaking table is the adjustable frequency shaking table.
Adopt the soft rock disintegration automatic sieving instrument of technique scheme, by utilizing water inlet pipe and rising pipe to come water level in the application cylinder, make carbonaceous soft rock in disintegrating procedue, be in Riddled Condition always, open simultaneously the adjustable frequency shaking table and make whole device be in vibrational state, thereby reach two effects that process is carried out simultaneously of disintegration and screening.This apparatus structure is reasonable in design, and is easy to install, efficient and the experimental precision of raising carbonaceous soft rock disintegration experiment that can be by a relatively large margin.
In order to solve above-mentioned second technical matters, the test method of soft rock disintegration automatic sieving instrument provided by the invention, test procedure is as follows:
(1), to choose diameter be the block original state soft rock that having of 80～120mm met the water disintegration properties, take by weighing the initial value quality after, put into the inner core of the superiors;
(2), open the water inlet pipe switch, make water in the instrument cover soft rock sample in the superiors' inner core;
(3), observe its disintegrating procedue by transparent inner/outer tube, meet this moment and will be entered by the screening hole of upper strata inner core each inner core of lower floor than granule after the water disintegration; As observe soft rock Particle Blocking sieve aperture and then open shaking table, make it smoothly by each inner core screening hole;
(4), when observing each inner core soft rock volume without significant change, close shaking table, open simultaneously rising pipe, water in the instrument is discharged, then take off each inner core and be placed on dry ventilation, in inner core soft rock disintegration product fully air-dry after, utilize the quality of disintegration soft rock in its each inner core of electronic scale weighing, and draw the grating distribution curve.
Innovation of the present invention is: soft rock disintegration automatic sieving instrument combines the disintegration in the soft rock slaking test and two processes of screening dexterously, has saved greatly the time of slaking test.And the loss of quality does not appear in the whole process of test, has improved the degree of accuracy of test findings.Make urceolus with transparent organic glass, make things convenient for the viewing test process.
In sum, invention be a kind of disintegrating procedue and screening process carry out simultaneously and efficiently, intuitively, strong operability and error less soft rock disintegration automatic sieving instrument and test method thereof.
