The on-line apparatus has the mature technology and the reliable principle, is simple to operate the device and the test, is high in measurement precision and sensitivity, is exact and reliable in data measurement, and can overcome the defects that the grains which are less than 0.075mm are hard to detect and the detecting time is long in the prior art.
Description
Technical field
The utility model belongs to civil engineering work search equipment technical field, is specifically related to a kind of online nucleon grogs degree analyser.
Background technology
At present, soil particle sreen analysis method commonly used both at home and abroad mainly contains sieve method, sedimentation, ultrasonic Method for Measuring, laser method etc.Wherein, sieve method is difficult to measure to the particle less than 0.075mm, sedimentation has transfer pipet method, sedimentation balance method and specific gravity balance method etc., though its use is more extensive, but not only Measuring Time is long, and measurement result often depends on technical level of operators, can't realize the online in real time control to measuring.And that ultrasonic Method for Measuring and laser diffractometry also exist working environment and sensor requirement is very high, and probe apparatus needs often to demarcate, and brings problems such as difficulty to maintenance.
Summary of the invention
The purpose of this utility model is at existing above-mentioned defective in the prior art, provide a kind of density of a certain depth level face soil particle suspending liquid in the special-purpose sample bucket of the online non-contact detecting of nuclear density gauge principle of utilizing to concern that over time the sedimentation analysis principle according to soil particle converses the particle diameter of soil particle and the online nucleon grogs degree analyser of grating situation thereof then.
The utility model is to realize above-mentioned purpose by the following technical solutions: this online nucleon grogs degree analyser, it comprises a radioactive source caesium
137, place the radioactive source caesium
137Lead system protection body, plumbous system protection body has a slotted eye, makes the radioactive source caesium
137The gamma-rays of being launched shines along a direction level, is disposed with supporting special-purpose sample bucket, the photodetector that holds sample soil suspending liquid along this horizontal direction of illumination, and photodetector links to each other with microcomputer system.
More particularly, described supporting special-purpose sample bucket is 3000ml for capacity, and fixed diameter is 150mm.
Principle of work of the present utility model is: tested soil particle is placed in the supporting special-purpose sample bucket through stirring abundant dispersion, and adds spreading agent, utilize the radioactive source caesium then
137The gamma-rays of emission is at sample bucket certain depth place level irradiation sample bucket, a part of gamma-rays because of and soil particle suspending liquid in atom take place to interact and be absorbed, what of absorption are relevant with the density of suspending liquid.And the gamma-rays of another part transmission converts electric impulse signal to through photodetector, delivers to microcomputer system again and carries out data processing and analysis, draws the data of soil particle particle diameter and grating thereof, shows on screen and printing.
The utility model has following advantage than prior art: (1) technology maturation, principle is reliable.
(1) device and test operation are simple, adopt online detection mode, measuring accuracy and highly sensitive, no artificial factor.
(3) adopt non-contact measurement, be not subjected to the influence of the factors such as pressure, temperature, viscosity of soil particle suspending liquid, measure the gained data accurately and reliably.
(4) scope of the utility model measurement is less than 75 microns, and the time of each soil sample test is 24 hours, therefore, has overcome the defective that the particle less than 0.075mm is difficult to mensuration and Measuring Time length of the prior art.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The utility model will be further described below in conjunction with drawings and Examples for the tool present embodiment.
Referring to Fig. 1, present embodiment comprises a radioactive source caesium
1371, places the radioactive source caesium
1371 lead system protection body 3, plumbous system protection body 3 has a slotted eye towards the right side, make the radioactive source caesium
1371 gamma-rays of being launched 2 shines supporting special-purpose sample bucket 4, photodetector 5 along the right direction level, and photodetector 5 is connected on the microcomputer system 6.With tested soil particle in supporting special-purpose sample bucket 4 through stirring abundant dispersion, and add spreading agent, utilize caesium then
137The gamma-rays 2 levels irradiation sample bucket of 1 emission, the gamma-rays of transmission is converted to electric impulse signal by photodetector 5, delivers to microcomputer system 6 again and carries out data processing and analysis, and show on screen and printing.
The specific operation process of present embodiment is as follows: at first, calibrate this nucleon grogs degree analyser, the air-dry soil sample that to sieve is then contained in the supporting special-purpose sample bucket 4, the capacity of supporting special-purpose sample bucket 4 is 3000ml, fixed diameter is 150mm, injects the suspending liquid that distilled water and an amount of hexa metaphosphoric acid solution stirring are made the uniform concentration of certain volume again in supporting special-purpose sample bucket 4.Open the switch of analyser and plumbous system protection body 3, the beginning level is shone supporting special-purpose sample bucket 4, in settling process, the density that detects the suspending liquid at surface level place reduces gradually, photodetector 5 and the microcomputer system 6 record density of suspending liquid ρ variations of t in time plot ρ-t figure with measurement result.According to Stokes principle and Standard for test methods of earthworks (GBT50123-1999), microcomputer system 6 is analyzed and deal with data, can obtain the particle diameter and the grating situation thereof of soil particle.
The test soil particle particle size range of present embodiment is less than 75 microns, and the time of each soil sample test is 24 hours.
