Abstract
The utility model provides a device for measuring sludge capillary water absorbing time, which comprises a substrate with a sandwiched structure, a filter paper and a glass plate, corners of the sandwiched structure is fixed through clamps, the center of the glass plate is provided with a tube, the upper end of the tube is provided with an opening, the bottom part of the tube passes through the glass plate to be closely matched with the filter paper, the glass plate is provided with scales, zero of the scales is arranged at the junction between the glass plate and the tube, and an indicator agent with the color being changed when in water is arranged inside a groove of the scales. When the device is in test, sludge is poured out of the tube, moisture is spread from the center of the filter paper along the filter paper under the gravity of the water and the capillary pressure of the filter paper, timing is begun from the zero of the scales, when the moisture reaches a designated scale, the timing is stopped, and the time interval is the capillary water absorbing time (CST) of the sludge. The device for measuring sludge capillary water absorbing time has a simple structure and is convenient to operate.
Description
Technical field
The utility model relates to a kind of device of measuring the mud capillary water absorption time.
Background technology
The test of CST (Capillary Suction Time) has showed a quick and reliable method of sludge filtration and state.From 1970, by external widespread use.At present, the device of measuring the CST of mud in the laboratory mostly is electronics and shows CST determination and analysis instrument, needs specific contact induction contact to be connected on the timer.Contact is fragile, and along with the increasing of access times, response lag can be brought certain error to mensuration.When measuring, relative slip easily takes place with contact in filter paper simultaneously.For the more mud of some solid contents, measuring error is bigger.And the cost height of this analytical instrument, maintenance difficult.
In view of above defective, be necessary to provide the device of a kind of improved mensuration mud capillary water absorption time to overcome above-mentioned defective in fact.
The utility model content
Technical problem to be solved in the utility model provides the device of a kind of simple in structure and mensuration mud capillary water absorption time easy to use, can measure the moisture in all kinds mud.
For achieving the above object, the utility model provides a kind of device of measuring the mud capillary water absorption time, the pedestal, filter paper and the glass plate that comprise sandwich structure, this sandwich structure is fixed with clip at the place, angle, and the central authorities of glass plate are provided with cylinder, the upper end open of this cylinder, the bottom run through glass plate and with the filter paper tight connecting, be carved with scale on the described glass plate, be the junction of glass plate and cylinder the zero point of scale, is provided with the indicator of meeting the water variable color in the cutting of described scale.
As most preferred embodiment of the present utility model, be marked with the mark circle that meets with the filter paper size on the described glass plate, this mark circle is provided with cylinder is concentric;
As most preferred embodiment of the present utility model, described cylinder and glass plate are integrally formed.
Compared with prior art, the device that the utility model is measured the mud capillary water absorption time has the following advantages at least: during the utility model device experiment, mud is contained in the cylinder, mud is under the capillary pressure of self gravitation and filter paper, moisture from the center of filter paper along filter paper to around diffusion, pick up counting zero point from groove, stop timing when moisture arrives the appointment groove, this time interval is exactly the capillary water absorption time (CST) of mud.The utility model apparatus structure is simple, and convenient test all can be measured the moisture in all kinds mud.
Description of drawings
Fig. 1 is the front elevation that the utility model is measured the device of mud capillary water absorption time;
Fig. 2 is the vertical view that the utility model is measured the device of mud capillary water absorption time.
Embodiment
Do detailed description below in conjunction with the device that accompanying drawing is measured the mud capillary water absorption time to the utility model:
See also Figure 1 and Figure 2, the device that the utility model is measured the mud capillary water absorption time comprises pedestal 1, the upper surface of pedestal 1 is fixed with glass plate 3, accompany filter paper 6 between described pedestal 1 and the glass plate 3, pedestal 1, glass plate 3 and filter paper 6 form sandwich structure, and is fixing with the clip 4 that can regulate elasticity at place, four angles.
Centre at described glass plate 3 is fixed with cylinder 5, the upper end open of this cylinder 5, and lower end and glass plate 3 are connected as a single entity good seal.Load onto after the used filter paper 6 of experiment, cylinder 5 and filter paper 6 coincide closely.On pedestal 1, be marked with and test the mark circle that meets fully with the filter paper size, the center of circle of the center of circle of this circle and the cylinder 5 of splendid attire mud is at same position, guaranteeing that mud pours into after the cylinder 5, the moisture in the mud be from circle centre position equably to around begin diffusion.
Scale 2 on the described glass plate is a zero graduation with the contact point of cylinder 5 and glass plate 3, is provided with scale 2 to orthogonal four direction all around, so that observe the rate of propagation of moisture.
Described scale is to form in glass plate 3 lower surface cuttings, and it is the indicator of variable color that chance water is housed in cutting.Shop one deck high-quality anhydrous slufuric acid copper powders may in cutting is brushed one deck hydrophile adhesive mass more in the above earlier, and repeatedly brushing after waiting to solidify is with colourless copper sulphate powder sealing.
When pour a certain amount of mud in cylinder 5, filter paper 6 capillary water absorption pressure " absorption " moisture from mud by producing, moisture infiltrate the filterableness of the main mud cake that relies on the state of mud and form of speed size of filter paper 6 on filter paper.When observing groove place at zero point change blueness, pick up counting, when reaching the groove of appointment, blue water mark stops timing.This two minor tick is exactly the CST of the mud of surveying.In order to preserve value, whether must pick-up unit before the experiment place abswolute level during mensuration to the speed unanimity of all directions diffusions.
In the utility model device, the diameter of cylinder 5 and height specification can artificially be set.Because the strength that mud produces by capillary water absorption, be far longer than self differential static pressure when static, so test does not rely on the quantity of mud in cylinder.
During test, measure the mud (as 50ml) of certain volume earlier with beaker, be poured into quickly and evenly in the cylinder 5.This mud can be through the mud after the conditioning of various chemical flocs, also without the primary sludge of any processing.Treat mud under the capillary pressure of self gravitation and filter paper, moisture from the center of filter paper 6 along filter paper to around diffusion, pick up counting zero point from groove, when moisture arrives the appointment groove, stop timing, this time interval is exactly the capillary water absorption time (CST) of mud.Be troubleshoot system errors, guarantee the accuracy of experimental data, same laboratory sample is done three experiments under the same conditions, ask its mean value.
The utility model device is simply light, assembling is quick.Before each experiment, to guarantee to test the abswolute level of base.When changing filter paper 6, guarantee transparency glass plate bottom drying at every turn, its indicator is solidified, there have blueness to become again to be colourless, and circulation repeatedly utilizes.Guarantee that cylinder 5 inwalls do not have mud residual, avoid the phase mutual interference between the different experiments sample.
The above only is a kind of embodiment of the present utility model, it or not whole or unique embodiment, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model instructions is claim of the present utility model and contains.
