Description
Technical field
The present invention relates to a kind of environmental protection equipment, specifically construction slurry is dewatered, make its process of being more convenient for, reduce the construction slurry treatment unit of environmental pollution.
Background technology
Along with the continuous quickening of Development of China's Urbanization, the construction of all kinds of engineering is in the ascendant, in the construction process such as pile foundation and pattern foundation pit supporting structure, create a large amount of construction slurries.According to statistics, the generation of China's construction slurry reaches several hundred million cubes every year.The composition of these mud is different from municipal sludge with character, based on clay mineral, natural subsidence and Direct Dehydration effect poor, if dealt with improperly, easily pollute environment, destroy water quality, block the harm such as municipal pipeline.The most original method of current employing is that working-yard is digged pit, piled dam, pinching, and by natural air drying, this method needs a large amount of places, air-dry cycle long (needing about 5 years), soil second ploughing difficulty, destroy ecological and dangerous.Some places government unifies the process of a searching professional landfill yard centralized collection, but there is limited, the uneasy congruent problem in place that the air-dry cycle is long, can hold mud equally, and this type of landfill yard is often away from city, very likely drives by interests and occur that the phenomenon of falling is stolen by the row of stealing.Also some places attempted carry out industrialization focus on, select horizontal centrifuge as major equipment to be separated mud, after process, the solid content of dry mud is only about 48%, and treatment capacity is less than normal, invest the project of about 1,000 ten thousand, day output only have 500 sides less than.
Summary of the invention
For overcoming above-mentioned defect, the present invention aims to provide one needs place little, and dewater to construction slurry fast, solid content is high, the treatment unit that treatment capacity is large.
For achieving the above object, the technical solution used in the present invention is: a kind of construction slurry treatment unit, comprise a suction pit, a settling tank and clean water basin, described suction pit is connected by a mud tube with between settling tank, described settling tank is connected by a clear water pipe with between clean water basin, described mud tube is added cartridge case by a chemical feed pipe be connected with one, described settling tank is connected with the import of one or more stacked spiral dewater by a secondary mud tube, described clean water basin are connected with suction pit by a return line, the water outlet of described stacked spiral dewater is connected with mud tube by rising pipe.
Described mud tube can substitute with height gravity flow ditch, and the available overflow groove of described clear water pipe substitutes.
Also be provided with a sludge concentrating pot between described settling tank and stacked spiral dewater, described sludge concentrating pot is connected by secondary mud tube with settling tank, described secondary mud tube by a secondary chemical feed pipe with add cartridge case and be connected.
Described clean water basin are also connected with secondary chemical feed pipe with chemical feed pipe respectively by the pipe that makes up a prescription.
Have employed construction slurry treatment unit of the present invention, by stacked spiral dewater, final dehydration is carried out to the mud through precipitation, and the clear water after precipitation is recycled deliver to suction pit and carry out washing away stirring, the clear water that clean water basin and stacked spiral dewater extrude simultaneously is recycled to deliver in chemical feed pipe and is made up a prescription, after substantially increasing process, the solid content of dry mud reaches more than 67%, it is first-class brick-making raw material, the trash content of clear water is only 0.3%, can system reuse or directly discharge, realize environmentally friendlyization, resource circulation utilization completely.

Embodiment
As shown in Figure 1, the invention discloses a kind of construction slurry treatment unit, comprise a suction pit 1, a settling tank 2 and clean water basin 3, described suction pit 1 is connected by a mud tube 4 with between settling tank 2, described settling tank 2 is connected by a clear water pipe 5 with between clean water basin 3, mud in suction pit 1 to be pumped in settling tank 2 by mud tube 4 by slush pump 17 and precipitates, for accelerating sedimentation speed, by also needing to add flocculation agent in mud, concrete way is that the flocculation agent adding cartridge case 7 is joined in mud tube 4 by chemical feed pipe 6, also need to add a certain amount of clear water in flocculation agent to dilute.Mud in settling tank 2 after the precipitation of certain hour, solid granule sinks to the bottom of settling tank 2, the clear water of settling tank 2 first half flows in clean water basin 3 by clear water pipe 5, precipitates further in clean water basin 3, to be detected qualified after can be discharged in natural stream networks.In sum, be the general processing mode in early stage of existing construction slurry.
Embodiment one: on the basis of existing building mud processing mode in early stage, innovative point of the present invention is mainly that described settling tank 2 is connected with the import of one or more stacked spiral dewater 9 by a secondary mud tube 8, described clean water basin 3 are connected with suction pit 1 by a return line 12, and the water outlet of described stacked spiral dewater 9 is connected with mud tube 4 by rising pipe 16.After mud precipitates in settling tank 2, the clear water on upper strata flows in clean water basin 3 by clear water pipe 5, the thick mud of bottom pumps into stacked spiral dewater 9 by slush pump 17 by secondary mud tube 8 and carries out processed, through actual measurement, dry mud solid content after processed up to more than 60%, directly can be transported and carry out the purposes such as brickmaking, landfill, simultaneously, extrusion clear water is out flowed into mud tube 4 again by rising pipe 16, mud tube 4 is washed away.In actual applications, one or more stacked spiral dewater 9 can be set according to treatment capacity.
In actual applications, described mud tube 4 can substitute with height gravity flow ditch 13, and described clear water pipe 5 can substitute with overflow groove 14.Height gravity flow ditch 13 is not easy to block with overflow groove 14, is easier to cleaning.
Meanwhile, dilute owing to also needing to add a certain amount of clear water in flocculation agent, described clean water basin 3 of the present invention are also connected with chemical feed pipe 6 by the pipe 15 that makes up a prescription.Utilize the clear water in clean water basin 3 to dilute flocculation agent, eliminate external tap water, saved cost of investment, also more energy-conserving and environment-protective.
Embodiment two: on the basis of embodiment one, a sludge concentrating pot 10 is also provided with between described settling tank 2 of the present invention and stacked spiral dewater 9, described sludge concentrating pot 10 is connected by secondary mud tube 8 with settling tank 2, described secondary mud tube 8 by a secondary chemical feed pipe 11 with add cartridge case 7 and be connected.After mud precipitates in settling tank 2, the clear water on upper strata flows in clean water basin 3 by clear water pipe 5, the thick mud of bottom pumps into sludge concentrating pot 10 by slush pump 17 from secondary mud tube 8, simultaneously, the flocculation agent added in cartridge case 7 adds in secondary mud 8 by secondary chemical feed pipe 11, to the precipitate and separate entering sludge concentrating pot 10 and have thick mud to carry out again, the water ratio of the mud entered in stacked spiral dewater 9 is reduced further, finally through actual measurement, the solid content of the dry mud after dehydration is up to more than 67%.
Meanwhile, with embodiment one in like manner, described clean water basin 3 of the present invention are also connected with secondary chemical feed pipe 11 by the pipe 15 that makes up a prescription.Utilize the clear water in clean water basin 3 to dilute flocculation agent, eliminate external tap water, saved cost of investment, also more energy-conserving and environment-protective.
