In the filtration test of mud, the mud of certain volume passes through the mistake of certain area under certain pressure effect Filter material material, the water of leak-off is referred to as fluid loss within the 30min times, in units of ml.In same experiment, filter material is attached to The thickness of dehydration clay particle Guinier-Preston zone on material is referred to as mud cake thickness, in units of mm.Fluid loss is to embody mud in hole pressing During being permeated in the presence of power difference to surrounding stratum, the performance indications of Free water filter loss size therein.Mud cake thickness is Weigh the index of mud wall building property.Determined mostly using Weight type mud wavter loss meter in the past, and passed through certain mass Pressurization weight reads filtrate volume to pressure slurry, and by graduated cylinder.Pressurization weight quality light can not be adjusted in test process, And water is overflowed using the progress described point drawing of artificial indrect reading for mud, and this not only can visually cause certain mistake Difference, and the change that sample overflows water can not be monitored in real time.
The content of the invention
The purpose of this utility model is to provide a kind of Pneumatic slurry dehydration tester, can not to solve existing instrument Regulate and control that test pressure, sensitivity is low and technical problems of trivial operations.
The utility model is in order to solve the above technical problems, the technical scheme used is:A kind of Pneumatic slurry fluid loss Air gauge, pressure-reducing valve, air gauge, the air pressure have been sequentially connected in series on tester, including air pump, the airway tube being connected with air pump Table is connected by gas transmission part with vent valve;
The gas transmission element outputs are connected with mud cap import, and the mud cup bottom perforate is simultaneously connected with weep pipe, The weep pipe decentralization is provided with measuring cup, and the measuring cup is placed on electronic balance tray.
Preferably, it also includes the experiment base of L-type, and pressure-reducing valve is installed in the experiment base upper end, and electronics is installed in lower end Balance.
Preferably, the junction of the airway tube uses stainless steel adapter.
Preferably, the mud cap inwall is provided with equidistant scale.
Preferably, the mud cap side wall is sealed using O-shaped rubber ring.
Preferably, bottom is equipped with filter paper in the mud cap.
Preferably, the weep pipe is connected with lead upper end, and the lead lower end is adjacent on measuring cup inwall.
The beneficial effects of the utility model:
1st, the fluid loss of mud and the measure of mudcake thickness are carried out simultaneously in same tester.
2nd, pressurization and release easily can be controlled using compressed gas at the top of tester.
3rd, filtrate can be continuously drained into measuring cup by weep pipe by lead, increase the precision of test.
4th, the tester is easy to carry, and can adapt in field test.
