Description

The waste mud handler

Technical field

The utility model relates to a kind of sludge treatment equipment, especially relates to a kind of waste mud handler, is used for the site disposal of railway, highway, bridge and heavy construction pile foundation boring discarded slurry.

Background technology

Bored pile foundation is adopted in railway, highway, bridge and heavy construction mostly, and boring procedure need utilize mud protection hole wall, carry drilling cuttings portals, cool off drill bit etc., the boring a large amount of discarded slurry of back generation that finishes.Discarded slurry is more stable colloidal dispersion, is difficult to precipitate and separate under field conditions (factors), and not treated discharging can be polluted surrounding environment.At present, the construction site is adopted the ways of shelving more, discarded slurry is concentrated in the suction pit leave standstill, and after precipitation for some time supernatant liquor is discharged, and remaining mud is transported.Because mud is difficult for natural sedimentation, often leaving standstill does not have the supernatant liquor generation for a long time yet, even produce supernatant liquor, amount also seldom meets unfavorable factors such as rainy weather again, makes this treatment process be subjected to very big restriction.The unit in charge of construction that also has directly clears discarded slurry, but because of mud belongs to fluid, can only use the tank car transportation, and need be transported to special place and handle and dispose, pollute otherwise can produce environment, therefore need a large amount of trucking costs of cost, and need large stretch of special place to handle waste mud.

Discarded slurry treatment technology at present commonly used mainly contains that chemical flocculation solid-liquid separation, chemical flocculation add mechanical dehydration, the chemosetting processing waits waste mud is handled.

The chemical flocculation treatment process is by adding flocculation agent in mud, destroy the chemical stability of mud system, water is separated with solid phase particles, make the discarded slurry decrement, being convenient to clear.After adopting chemical flocculation to handle, discarded slurry is separated into supernatant liquor and precipitation bed mud, and supernatant liquor is answered qualified discharge, and the water ratio of precipitation bed mud should be low as far as possible, and quantity is the least possible.The subject matter that adopts this method to exist is that the volume of precipitation bed mud can account for more than 80% of cumulative volume, and therefore, decrement is limited, and the transportation processing costs is still very high.

Mud moisture content after chemical flocculation and the precipitate and separate is still higher, therefore carries out mechanical dehydration again after separation, and solid volume is further reduced, and is convenient to transportation, and this method is chemical flocculation and adds the mechanical dehydration method.Dewatering machine commonly used at present has whizzer, belt filter press and plate and frame(type)filter press etc.Whizzer is applicable to the less situation of solid phase particles diameter, whizzer is removed the I of solid grain size and is reached 0.006～0.008mm, for clay, a lot of grain diameters are still less than this, so can't remove whole clay particles with whizzer merely, test-results shows that also rotating speed is the bed mud after the whizzer of per minute 1500 commentaries on classics is handled coagulating sedimentation, it is muddy that water outlet remains, and the whizzer noise is big in addition, energy consumption is high, maintenance difficult.Belt filter press is subjected to, and the mud fluctuation of load influences that but little non-stop run, mud extraction water ratio are lower, working stability, less energy consumption, need before the mud to make mud form big floc sedimentation to the mud flocculation agent that dewaters in advance-promptly add but advance, and floor space and volume is bigger.Plate-and-frame filter press and chamber-type press filter mud extraction solid content are than belt filter press height, and dehydrating effect is good, but its mode of operation is step, must carry out dump behind the one-period, has increased the workload of site operation.Above-mentioned mechanical dewatering equipment is all handled discarded slurry in the special place away from the scene, and trucking costs is still very high.

The chemosetting method is to make its stable method in the middle of the method with physical-chemical is included in inert material with objectionable impurities, by in discarded slurry, adding solidifying agent or peptizer, make moisture minimizing in the mud, be formed with the stable anti-water solid of certain intensity, solidifying agent generally has cement etc., and solidification method primary treatment amount is big, and treatment effect was also better when pollutant load was higher, but the treatment process relative complex, expense is higher.

At present, be applicable to the on-the-spot instant equipment of handling waste mud seldom, in the engineering adopt in settling tank natural sedimentation and discharge supernatant liquor to reduce the mud volume, be transported to the method for disposal of landfill yard then with tank car,, can not realize solid-liquid separation so often leave standstill for a long time because mud is difficult to natural sedimentation, when heavy rain or other unforeseen circumstancess occurring, be prone to the excessive and contaminate environment of mud, the time of therefore handling the waste mud cost is long, the trucking costs height; Adopt tank car to transport to the waste field and dispose, trucking costs is higher, and some unit in charge of construction is reluctant to bear the trucking costs of great number and promptly suction pit is not carried out landfill to discarded slurry is treated, causes mud to overflow, environment and water body around polluting.
