Description

A kind of sludge curing test specimen producing device
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 Close to solidification sludge truth, the closely knit bubble-free of sample, high homogeneity, the solidification sludge sample preparation device of high reproducibility.
To achieve the goals above, its technical solution is that:
A kind of sludge curing test specimen producing device, the producing device are controlled by stocking system, sample-preparing system and intelligence Platform system composition processed, wherein stocking system is made of plunger shaft, rubber bag and piston rod, and sample-preparing system is by note sample pipette tips, ring Knife mold, steel casing, permeable stone, bead and pedestal are constituted, and intelligent control rack system is by holder, plummer and computer It constitutes.
It is equipped with rubber bag in plunger shaft, rubber bag is located at piston rod front end, and plunger shaft upper end is equipped with feeding warehouse, under feeding warehouse End is tightly connected with rubber bag, and feeding warehouse is respectively arranged with the first control valve and evacuating valve with rubber bag junction, is evacuated Valve is located at the lower section of the first control valve, and plunger shaft lower end is equipped with discharge nozzle, and discharge nozzle upper end is tightly connected with rubber bag, steel Matter casing is movable to be placed in above pedestal, and cutting ring mold is set in steel casing, and note sample pipette tips, note are set in cutting ring mold Feeding-passage, sheet rubber and return flow line are provided in sample pipette tips, sheet rubber upper end is fixed on feeding-passage and connects with return flow line Logical place top is provided with permeable stone, is equipped with bead below permeable stone, bead is located on pedestal between cutting ring mold and pedestal It is square, it is provided with gas vent on pedestal.
Stocking system is fixed at pedestal upper end, and plummer is arranged at the lower end of the stand, plummer both ends by gear with Holder engages, and pedestal is placed in above plummer, and stress induction device, stress induction device, carrying are provided between pedestal and plummer Platform, piston rod are connect with computer respectively, and the lower end of the upper end and discharge nozzle of noting the feeding-passage of sample pipette tips is tightly connected, discharging Pipe is equipped with the second control valve.
As a result of above technical scheme, a kind of sludge curing test specimen producing device of the invention, using in work It fills in intracavitary and rubber bag is set, and controllable charging and discharge port are set in rubber bag, ensure there is no moisture content in sample making course Evaporation and stink diffuse;By the way of vacuum suction and piston press, ensure that the uniform no air of initial feed, sample preparation are fast Speed;The powered compressor piston of the note sample pipette tips combination computer control of use and the plummer equipped with inductor, ensure sample preparation 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.
