The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
Dystopy stabilization/curing improvement method has comprised the process procedures such as excavation, transhipment, fragmentation, adjusting pollutants water ratio, the stabilizer mix to pending pollutants processed, the rear output of processing, later use, its cardinal principle is fully to be mixed with pending contaminant particle, reacted equably by stabilizer, heavy metal is transformed into stable form, can again discharge harm environment because ambient environment change.And can to it, be cured processing according to pollutants later use form, process after stain thing and can do Roadbed Soil or building materials use.Conventionally, the mobile property of pending pollutants problem poor, that easily glue wall and accumulation is a large factor that affects dystopy curing/stabilizing disposal system efficiency.For example, utilize traditional storage silo storage as the pending thing of soil, waste residue one class, usually exist pending thing blanking not smooth, the easy problem at storage silo narrow positions stacking material.
In order to realize the present invention's object, the embodiment of the present invention has proposed a kind of storage silo, described storage silo comprises cylindrical warehouse and lower end cone, identical and the lower end cone of cone side, described lower end and cylindrical warehouse bottom surface size is closely connected with cylindrical warehouse, and cone side, described lower end and inclination angle, cylindrical warehouse bottom surface are greater than 60 degree.Schematic diagram as shown in Figure 1.With respect to general storage silo conical section inclination angle, be not more than the design of 45 degree, because the viscosity of pending thing is larger, easily sticky wall, conglomeration in storage silo, cause occurring for medicine, the discontinuous phenomenon of discharging, therefore, the above-mentioned storage silo that the present invention proposes, during as pollutants storage silo, can solve the problems of the technologies described above.By making conical section that larger lower material space and more precipitous blanking channel are provided, expand feed opening diameter, as shown in Figure 1, by above-mentioned transformation, the resistance of pending thing when storage silo can effectively reduce whereabouts, during operation, pending thing can be discharged to smoothly on belt electronic scale from storage silo.
In addition, lower end cone can be further improved, and cone sidewall has one or more cavernous structures, and described cavernous structure is for external pneumatic arch breaking apparatus.For example, at conical section, be densely covered with three layers pneumatic " broken arch " device, every layer of 8 hole, around cone circle distribution, prevent that conical section generation raw material from blocking the problem that pending thing cannot blanking that makes.Connect pneumatic arch breaking apparatus storage silo schematic diagram as shown in Figure 2, pressurized air enters a minute gas tank, then by flexible pipe, links the cavernous structure of cone sidewall.
Traditional storage silo may dispose vibrator and similarly install, to strengthen the flowing power of material, but larger as soil/waste residue viscosity, vibrator can make pending thing pile up more closely knit and more closely knit at storage silo conical section on the contrary, thereby extend the cycle of run of whole system, directly affect the particularity that pending thing weighs.Now adopt the pneumatic broken arch of multilayer, it,, by compressed-air actuated impact failure arch form balance, makes uniform blanking, meets measuring accuracy requirement.For preventing that aqueous vapor from further entering material, make material caking, can charge of oil water separator in gas circuit.
Conventionally, pending thing exit is provided with the metering device that can effectively guarantee material consecutive weighings, as embodiments of the invention, adopts belted electronic balance to weigh, and measuring accuracy is high.And storage silo feed opening directly by mass transport to belt conveyer scale, reduced as much as possible mass transport link, also evaded the problem such as poor fluidity in course of conveying.
Because pending thing viscosity is large, water ratio is higher, in stabilizing treatment process, the stirring between stabilizer and soil/waste residue can cause occurring stirring difficulty, agglomerating, the sticky wall of material, stirring phenomenon inhomogeneous and that production efficiency is on the low side conventionally.
In order to realize the present invention's object, the embodiment of the present invention has proposed a kind of puddle mixer of repairing for dystopy curing/stabilizing, described puddle mixer is continuous single-shaft horizontal stirrer, the stirring vane of described puddle mixer is ploughshare shovel shape, the stirring vane alternating expression of described ploughshare shovel shape is arranged on horizontal rotating shaft, two stirring vane angles are 120 degree, and described horizontal rotating shaft is placed in the stirred vessel of described puddle mixer.
That is, its main body of puddle mixer is continuous single-shaft horizontal stirrer.In addition, its agitating element, for meeting the requirement of soil/waste residue stabilizing treatment, can adopt the ploughshare shovel shape of marginal belt sawtooth.Furthermore, can also in stirred vessel wall, dispose special projection.
As shown in Figure 3, this puddle mixer stirring vane adopts class ploughshare shovel shape, is specifically arranged on horizontal shaft and is rotated, and horizontal shaft is arranged in the stirred vessel of a horizontal cylindrical.Being arranged on horizontal shaft of stirring vane alternating expression, jagged inclination ploughshare edge configuration, material can be radially and be scooped up from agitator wall, prevent that soil/waste particle is extruded between stirring vane and bucket wall, and can prevent the accumulation of soil/waste particle on bucket wall.Also prevent from forming dead angle or low-speed motion district in whipping process, promote accurate mixing at a high speed simultaneously.On agitator wall, between two stirring vanes, be distributed with one or more small-sized raised structures, these project organizations can further increase repeating between material particles in stirred vessel and push, and strengthen the friction force between material particles and bucket wall.And the geometric configuration of agitating element and the optimal combination of position can form strong shearing force and squeese pressure to material in agitator, strengthen the mixture homogeneity of stabilizing treatment, and there is good material breaking capacity.
Conventionally, mixing equipment all adopts a puddle mixer for mixture operation, and this is difficult to be applicable to be directed in stabilizing treatment viscosity, pending thing and stabilizer mixture operation that water ratio is higher; And in order to simplify the processing step of stabilizing treatment, the continuous working aspect pending thing fragmentation, adjusting water ratio, stabilizer mix, by technological demonstration and practical experience, the present invention proposes the stabilizing treatment system of many puddle mixers interlocks.

One-level puddle mixer is for by being uniformly mixed of pollutants and water, further that pollutants is broken, and regulates the water ratio of pollutants; Secondary puddle mixer is uniformly mixed for pollutants and stabilizer.
Its reason is that traditional forced action type continuous mixer adds for stabilizer and the interpolation of water is simultaneously, is unfavorable for the even mixing of stabilizer.The interpolation of stabilizer and water is as follows on the impact of degree of uniformity:
| Order of addition | Mixture homogeneity | Applicable |
| Add stabilizer and water simultaneously | Low | ? |
| After first adding stabilizer, add water | High | Sandy soil |
| After first adding water, add stabilizer | High | Clay |
Furthermore, stirring system also comprises three grades of puddle mixers, and three grades of puddle mixers are for repeatability stirring again, until reach the desired mixture homogeneity of predetermined stabilization effect.For example, the system of mixing and stirring also comprises puddle mixer C, and the input of described puddle mixer C is connected with the output of described puddle mixer B; Described puddle mixer C is for receiving the pollutants of puddle mixer B output, by pollutants and stabilizer mix again, to guarantee stabilization effect, and/or utilizes mode to pass through C puddle mixer by pollutants and curing agent mix according to follow-up pollutants.Conventionally, if follow-up pollutants is direct landfill or original place backfill, complete after stabilization.If recycle for resource, such as purposes such as Roadbed Soils, may there is requirement to the compressive strength of stabilization product, need to carry out being cured again processing after stabilization to pollutants, therefore can further pass through C puddle mixer by pollutants and curing agent mix.
