Description
Technical field
The present invention relates to a kind of sludge curing test specimen producing devices, belong to environmental geotechnical technical field.
Background technology
With the continuous improvement for the treatment of rate of domestic sewage and treating capacity, the processing handling problems getting worse of municipal sludge.
Sludge sanitary landfills due to small investment, capacity is big, processing is fast the advantages that, be still the most commonly used side of China's Treatment of Sludge at present
Method.But the sludge after sewage treatment plant's dehydration, moisture content are still up to 75% or more, are unable to reach and directly fill out
The intensity requirement of disposition is buried, curing process must be carried out to sludge.
G., jelly-like is presented in the characteristics of sludge is due to high-moisture percentage and high organic, has mobility, visco-plasticity, with solidification
After agent stirring, weaken in solidification initial flux, visco-plasticity enhancing, passes through the method system of compacting in no image of Buddha soil test specification
Sample.
There is presently no special solidification sludge sample preparation device, the correlation technique and device that can use for reference soil test make admittedly
Change mud sample, there are mainly two types of methods：(1) harvesting：By after sludge integrally curing in bulk container, then cutting ring jacking is whole
Body firming body cuts sample, this method is simple and practicable and sample preparation is rapid, but materials are more, and waste is more, and sampling process disturbs greatly sample,
Destroy the structure of sample after curing；(2) die methods：Sludge after being stirred with curing agent is poured into mold conserve and is determined
Type takes out after then reaching certain curing time, and this method materials are few, but time-consuming for filling process, and entire space stink is more
It is unrestrained, be easy to be mixed into bubble when pouring into the mud after being stirred in mold and be not easy to be discharged, the otherness of sample and sample compared with
Greatly, it can not ensure the homogeneity of sample.
Invention content
In view of the above problems, the purpose of the present invention with provide one kind save material, quickly, mechanical behavior more

Journey solidification sludge is tightly packed with mold cutting ring；Computer controls piston rod and sample is squeezed into note sample pipette tips, into cutting ring sample bottom
Portion, and being spread to cutting ring surrounding, when continuing to squeeze, excessive sample gradually fills up cutting ring bottom, and when continuous extrusion, sample can lead to
It crosses return flow line and enters and form closed circuit in feeding-passage, and then pedestal is caused to increase the stress of plummer, stress induction
Device transfers data to computer in real time, when stress increases to certain value (50kPa), under computer control plummer is slow
Drop, while the compression speed of piston rod is controlled, so decline (mold height) the i.e. stopping that reaching a certain height and compress and decline, takes
Go out sample to be sealed with plastic film packaging, a sample completes.
The producing device of interior solidification sludge sample provided by the invention solves existing indoor solidification sludge preparation facilities
In, materials are more, and time-consuming, and stink diffuses, and sample is easily disturbed, easily formed hole be not easy it is closely knit can not ensure sample homogeneity,
The low problem of sample reproduction degree.While materials can be saved and reduce stink in environment, producing for fast and stable is closely knit equal
One sample, while otherness is small between ensureing sample, sample reproduction degree is high, and related examination is carried out to the solidification sludge of same property
It tests, is conducive to stablizing for experimental data and obtains, reliable accurate necessary data are provided for solidification treatment disposition.
