Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is overall structure schematic diagram of the present utility model, and the arrow among the figure is liquid flow direction.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Among the figure: pulp-inlet pipe 1, whirl cylinder 2, annular overflow plate 3, water delivery chamber 4, with one heart bevel-type sand sediment pipe 5, clear liquid chamber 6, annular water collecting dike 7, outlet pipe 8, thick slag bucket 9, thin slag bucket 10, mud concentration tube 11, slag notch valve 12, bottom bracket 13, the first cylindrical shells 14, the second cylindrical shells 15.
The specific embodiment
In Fig. 1, a kind of body refuse treating apparatus for pressure type water-pumping/draining exit comprises that the first cylindrical shell 14, the first cylindrical shells 14 bottoms are provided with thin slag bucket 10,10 one-tenth top little tapers in the large end of thin slag bucket, and thin slag bucket 10 bottoms are provided with mud concentration tube 11;
The second cylindrical shell 15 is installed in the first cylindrical shell 14, forms water delivery chamber 4 between the second cylindrical shell 15 and the first cylindrical shell 14; In the water delivery chamber, liquid flows from top to bottom.
Whirl cylinder 2 is installed in the second cylindrical shell 15, whirl cylinder 2 bottoms are provided with the thick slag bucket 9 that is communicated to thin slag bucket 10,10 one-tenth top little tapers in the large end of thin slag bucket, whirl cylinder 2 is connected by annular overflow plate 3 with the top of the second cylindrical shell 15, described annular overflow plate 3 is higher near an end in the center of circle, and lower away from an end in the center of circle.
Top between whirl cylinder 2 and the second cylindrical shell 15 is provided with clear liquid chamber 6, and the bottom is provided with the concentric bevel-type sand sediment pipe 5 that is communicated with clear liquid chamber 6.In the scheme of optimizing, described concentric bevel-type sand sediment pipe 5 is the conically shaped of a plurality of arranged concentric.Described concentric bevel-type sand sediment pipe 5 is positioned at the position of the outer wall of thick slag bucket 9.In the scheme of further optimizing, described conically shaped is multilayer, and spacing is consistent between each layer, and the conically shaped in this example is three layers.Concentric bevel-type sand sediment pipe 5 in this example has creatively used tube settling and shallow pond precipitation principle, and for example: establishing the tube settler pond long highly is H for L, and horizontal flow velocity is v in the pond, and the heavy speed of particle is u0, in the ideal situation, and L/H=v/ u0.When as seen L and v value were constant, the pond body was more shallow, and is can removed suspended particle less.If use horizontal baffle, H is divided into 3 layers, whenever be H/3 layer by layer deeply, under the constant condition of u0 and v, only need L/3, just can be with the particle removal of u0.Also be that total measurement (volume) can reduce to original 1/3.If the pond is long constant, because the pond be H/3 deeply, then horizontal flow velocity can increase to 3v, still can remove for the particle of u0 sinking speed, and also soon sedimentation basin is divided into the n layer and just can improves n times to disposal ability.And adopt three layers of bevel-type sand sediment pipe 5 that arrange with one heart in this example, in the highly constant situation of whole device, realized the combination that tube settling and shallow pond are precipitated.
Be provided with the annular water collecting dike 7 that the top is communicated with clear liquid chamber 6 in the clear liquid chamber 6, the bottom of annular water collecting dike 7 is provided with outlet pipe 8; Water after the separation is discharged from from outlet pipe 8, thereby has effectively reduced environmental pollution.
Pulp-inlet pipe 1 passes the first cylindrical shell 14, the second cylindrical shell 15 and annular water collecting dike 7 and is communicated with whirl cylinder 2.In the scheme of optimizing, as shown in Figure 2, the mode with the barrel inscribe between pulp-inlet pipe 1 and the whirl cylinder 2 is communicated with.Structure has realized the cyclonic separation function at whirl cylinder 2 thus.
Described mud concentration tube 11 is provided with slag notch valve 12.Described the first cylindrical shell 14 bottoms are provided with bottom bracket 13.
As shown in fig. 1, during use, the liquid of pumping drainage pipe outlet enters whirl cylinder 2 by pulp-inlet pipe 1, cut intersects in the barrel of the tube wall of pulp-inlet pipe 1 and whirl cylinder 2, make liquid in whirl cylinder 2 interior rotations, because the density of slag and liquid is different, the slag that density is large sinks down into thick slag bucket 9, thick slag bucket 9 is up big and down small, is convenient to body refuse downslide and concentrated.The concentric bevel-type sand sediment pipe 5 that also helps with its outer wall position makes up installation.
Contain the liquid of the less granule slag of density through overflow plate 3, entering the 4 rear changes of water delivery chamber flows to, low speed passes through the concentric bevel-type sand sediment pipe 5 of multilayer from bottom to up, the number of plies of bevel-type sand sediment pipe 5 is more with one heart, liquid flows from bottom to top at each interlayer, to have reduced settling height to each layer body refuse, the sedimentation of having accelerated body refuse.Little large under the conically shaped, liquid flows from bottom to top, and flow velocity further descends, and has further promoted the sedimentation of body refuse.
Liquid continues to make progress to clear liquid chamber 6, and the mode with overflow enters annular water collecting dike 7 again, discharges by the outlet pipe 8 of annular water collecting dike 7 bottoms at last; The fine grained body refuse enters thin slag bucket 10 by the tube wall downslide of concentric bevel-type sand sediment pipe 5.Slightly, the fine grained body refuse concentrated in thick slag bucket 9 and thin slag bucket 10 respectively after, it is further concentrated to enter mud concentration tube 11.Body refuse after concentrated is regularly discharged by slag notch valve 12.Realize thus the effect that slag liquid separates.
