It is shown in Figure 1 to form schematic diagram as structure, the present invention includes flow and adjust the pond, mud cleaning system, the mud regulating tank, slurry storage tank and be connected in slurry transportation system between them, wherein said flow is adjusted the slurry transportation that being connected of the muddy water storehouse of pond by slurry transportation system and excavating equipment realizes the needs in the muddy water storehouse are handled to flow adjustment pond, the input of described mud cleaning system is adjusted the purified treatment that realizes being connected of pond mud by the slurry transportation system with flow, and its output by the slurry transportation system with realize purifying the back mud veclamation being connected of mud regulating tank to the mud regulating tank, density to mud, viscosity, technical datas such as proportion are regulated, and make the mud parameters reach the requirement of construction technology.Described slurry storage tank is connected with the mud regulating tank, forms a jumbo mazy mud pit.Described mud regulating tank realizes that by being connected of muddy water storehouse of another slurry transportation system and excavating equipment the mud with through adjusting after handling is fed back to the muddy water storehouse of excavating equipment, thereby reaches the purpose that mud circulation is utilized.In order to guarantee that mud contains the quarrel amount and reduces to and meet the construction requirement scope, make the present invention can be applicable to the sand of handling various different soil properties, above-mentioned mud cleaning system comprises one-level mud purification machine and secondary mud purification machine, wherein, but described one-level mud purification machine is to be made up of the mud purification machine of the sand grains of at least one filtration treatment particle diameter 〉=74 μ m (for example ZX500 type mud purification machine), but described secondary mud purification machine is to be made up of the mud purification machine of the sand grains of at least one filtration treatment particle diameter 〉=45 μ m (for example ZX250 type mud purification machine), and described one-level mud purification machine links to each other with secondary mud purification machine by the slurry transportation system.In order to guarantee the continuous of construction working, carry out efficiently, but but above-mentioned mud cleaning system also comprises the standby clearing machine of one-level mud be made up of the mud purification machine of the sand grains of at least one filtration treatment particle diameter 〉=74 μ m and the standby clearing machine of being made up of the mud purification machine of the sand grains of at least one filtration treatment particle diameter 〉=45 μ m of secondary mud, wherein, the input of the standby clearing machine of described one-level mud and output are connected with the input and the mud regulating tank of above-mentioned one-level mud purification machine respectively by the slurry transportation system, the input of the standby clearing machine of described secondary mud and output by the slurry transportation system respectively with the output of above-mentioned one-level mud purification machine, the output and the mud regulating tank of the standby clearing machine of one-level mud are connected.As shown in Figure 1, above-mentioned slurry transportation system is made up of slush pump 3, valve 2 and slurry transportation pipeline 1.
Shown in Figure 2 as fundamental diagram, operating principle of the present invention is such: the circulation between excavating equipment and the muddy water treatment system is realized by the slurry transportation system, excavating equipment excavates the native sand that gets off and enters the muddy water storehouse, high-density slurry after the stirring system of excavating equipment stirs is pumped to flow and adjusts in the pond by slush pump and mud tube, and then adjust dredge pump in the pond and be pumped into mud cleaning system and handle screening by being arranged at flow, slurry transportation mud regulating tank after the separation, through adjusting density, be pumped back to the muddy water storehouse of excavating equipment after the indexs such as viscosity again, so circulation is recycled.Mud cleaning system is divided one-level desanding device and secondary desanding device, and its disposal ability and sieving capacity have nothing in common with each other, and the secondary desanding device is looked actual construction situation need determine whether open.The mud regulating tank links to each other with slurry storage tank, forms a jumbo mazy mud pit, plays a part to size mixing and hold slurry.
The method of the above-mentioned device for separating mud and water of the invention process, its step is as follows:
(1) before first the excavation, utilizes pulper to produce to meet the mud of the viscosity that soil property requires, and mud is packed into the mud regulating tank, and be filled to the design elevation of mud regulating tank;
(2) when excavating equipment excavates, the slurry transportation in the mud regulating tank is arrived the muddy water storehouse of excavating equipment by slush pump and slurry transportation pipeline;
(3) excavating equipment excavates the sand that gets off and enters the muddy water storehouse, and the highdensity muddy water that stirs into through the mixing plant of excavating equipment is transported to flow by slush pump and slurry transportation pipeline and adjusts the pond and carry out preliminary sedimentation;
(4) sending the slurry transportation that flow is adjusted the pond to starch quarrel to mud cleaning system by slush pump and slurry transportation pipeline separates;
(5) slurry transportation after will separating is to the mud regulating tank, and isolated quarrel soil is transported outward by vehicle;
(6) mud after separating after adjusting to the density that meets construction requirement, viscosity, is carried go back to the muddy water storehouse by slush pump and slurry pipeline at regulating tank again.
Can starch quarrel continuously, efficiently for above-mentioned device for separating mud and water and handle, above-mentioned steps also comprises the steps: in (4)
(4-1) proportion and the sand content of the mud after the one-level mud purification machine of mud cleaning system is starched the quarrel separation are reduced in the zone of reasonableness, and mud directly is recovered to the mud regulating tank;
(4-2) proportion and the sand content of the mud after the one-level mud purification machine of mud cleaning system is starched the quarrel separation are not reduced in the zone of reasonableness, by regulating the valve on the conveyance conduit, slurry transportation is screened out once more to secondary mud purification machine, and then be recovered in the mud regulating tank;
(4-3) one-level mud purification machine or secondary mud purification machine break down, can be by regulating the valve on the conveyance conduit, mud is switched to the standby clearing machine of one-level mud or the standby clearing machine of secondary mud is handled.
In order effectively to guarantee the service behaviour of slush pump, reduce abrasion, reduce the resistance of conveyance conduit, the general proportion of above-mentioned mud after the mud regulating tank is regulated is 1.00～1.50 among the present invention.Because: if use the bigger mud of proportion, not only can reduce the ability of slush pump, also can increase the resistance of pipe arrangement.On the contrary,, then can reduce the stability of excavation face, cause the increase of boundary settling rate, increase the danger of stopping up if proportion is less.Therefore, present embodiment is according to the slush pump designed output, and it is in 1.10～1.30 scopes that mud is controlled at best proportion.Equally, the viscosity number of mud also can influence the complete equipment normal operation, because use the lower mud of viscosity, the decline that will cause excavating face stability.Simultaneously,, also can increase the resistance of pipe arrangement, accelerate the abrasion of pipe arrangement, slush pump because mud can not wrap up the particle of solid matter.Thereby above-mentioned viscosity number after the mud regulating tank is regulated is elected 10～50sec as among the present invention.To reach resistance and the abrasion that reduce pipe arrangement, slush pump, guarantee the complete equipment normal operation.
