Abstract
A precipitation tank capable of providing excellent solid matter setting characteristics by a rather simple structure, wherein a raw water is fed into a feed well (12), flows mainly from the bottom face (11a) of a tank body along the inner peripheral wall surface (11b) of the tank body, overflows an overflow weir (15), and is discharged from a clarified water discharge tube (16). While the raw water flows along the inner peripheral wall surface (11b) of the tank body, the water can be efficiently settled since the water flows between tilted plates (14). Deposit flows from the inner peripheral wall surface (11b) along the bottom face (11a) of the tank body, flows into a pit-like discharge part (13), and is discharged from the discharge part to the outside of the tank body (11).
Description
Technical field
The present invention relates to be used for sedimentation separation handles the stillpot (settling separation device) of unboiled water, relate in particular to the stillpot of following structure, that is, the unboiled water at least a portion that supplies to the central portion of cell body rises and becomes primary water along the internal perisporium face of cell body, and this primary water flows out from overflow part.
Background technology
Settling separation device has natural subsidence separator, inclination settling separation device, aggegation settling separation device etc.The natural subsidence separator has rectangle and circular device, and rectangular device is generally horizontal-flow type, is called as the cross-flow type sedimentation basin, and circular sedimentation device has up flow type and horizontal-flow type, adopts horizontal-flow type under the situation that with the clarification is purpose.
The cross-flow type sedimentation basin easily produces density current, therefore inflow, outflow rectification wall and middle rectification wall is set so that the homogenising that flows realizes the raising of separative efficiency.Circular sedimentation device makes the mud of sedimentation mud compile easily.Fig. 4 represents the structure example of circular subsider.In this circle subsider, be fed into the unboiled water at center well 2 places of the central authorities that are arranged at cell body 1 through unboiled water supply pipe 3, expand to the bottom of cell body 1 from the bottom of this center well (central well) 2, in cell body 1, rise then, sedimentation separation solid constituent during this period, primary water flows to outside the cell body from downflow weir 4 overflows.Sedimentation mud by the collection mud that drives by drive unit 5 rotation with rake (rake) 6, and be pooled in the spoil disposal portion 7, and discharge through discharge pipe 8.
The inclination settling separation device is a kind of device that inserts hang plate or level board in subsider, the following generation clarified solution of plate, and the use principle of this device is that along with the increase settling area that inserts area becomes many, the formation speed of clarified solution accelerates.Thereby, can increase separating area pro rata with the insertion area of plate, thereby can reduce water surface load (m
3/ m
2H), so the less particle of separable sinking speed.
In real fair 5-45363 communique, spy open flat 5-200205 communique etc., record such subsider with hang plate.But, at real fair 5-45363 communique, the spy opens in the subsider of flat 5-200205 communique, is that hang plate is arranged in the bigger scope, so the cost height.

Summary of the invention
The object of the present invention is to provide a kind of stillpot of sedimentation separation excellent of relatively simple for structure and solid constituent.
Stillpot of the present invention supplies at least a portion of the unboiled water in the cell body central portion, rises along the internal perisporium face of this cell body, becomes primary water and flows out from the overflow part on this cell body top, it is characterized in that, is provided with hang plate along the internal perisporium face of this cell body.
In stillpot of the present invention, supply to the major part of the unboiled water in the cell body central portion, moving along the cell body bottom to cell body internal perisporium surface current, then rise along this internal perisporium face, carry out the sedimentation separation of solid constituent during this period and handle, primary water is from the overflow part overflow on cell body top.
In the present invention, because this cell body internal perisporium face is provided with hang plate,, can carries out sedimentation separation expeditiously and handle between the rising stage along this cell body internal perisporium face so work as water.In the present invention because hang plate is just enough along the setting of cell body internal perisporium face, so compare with existing example, hang plate be provided with that number is less to get final product, thereby make the simple in structure of device, and make the cost of apparatus structure also cheap.

The specific embodiment
Below, with reference to figure 1,2a and 2b, describe for optimal way of the present invention.
In the described stillpot 10 of present embodiment, cell body 11 is circular, and portion is provided with feed well 12 in the central.This feed well 12 is the cylindric of both ends open up and down, and its upper end protrudes in the top of the water level in the cell body 1.In the center bottom of cell body 1, be provided with the discharge portion 13 that is used to compile and discharges the concavity of the solid constituent after the sedimentation.
The bottom 11a of cell body 11 forms, and is cone shape to descending slope from the lower end of the internal perisporium face 11b of cell body 11 to central authorities.
On the internal perisporium face 11b of this cell body 11, be provided with a plurality of hang plates 14.Each hang plate 14 is the rectangular tabulars of cardinal principle, is fixedly installed on the internal perisporium face 11b on the long limit of one.Each hang plate 14 interval each other is certain, and the tilt angle theta of each hang plate 14 (elevation angle with respect to the horizontal plane) is also identical.The tilt angle theta of this each hang plate 14 is 45 °～80 °, is preferably about 55～70 ° degree especially.Hang plate 14 is arranged on the complete cycle of internal perisporium face 11b.In the present embodiment, the lower end of hang plate 14 is positioned at from the top of cell body bottom surface 11a predetermined distance.In addition, the upper end of hang plate 14 is positioned at the below of the water level of cell body 11.The horizontal wide L of hang plate 14 be preferably cell body 11 radius about 10～30%.
Be provided with downflow weir 15 as overflow part along the top of internal perisporium face 11b.
In the stillpot 10 of said structure, unboiled water mainly flows from cell body bottom surface 11a along cell body internal perisporium face 11b after being fed in the feed well 12, is discharged by primary water discharge pipe 16 from downflow weir 15 overflows again.Along between this cell body internal perisporium face 11b flow periods,, can carry out sedimentation separation expeditiously and handle by flowing through each other from hang plate 14.Precipitum flows from internal perisporium face 11b along cell body bottom surface 11a, flows in the discharge portion 13 of concavity, is discharged to thus outside the cell body 11.
In the present embodiment, hang plate 14 is the veneer shape that only tilts to a direction, but also can be as shown in Figure 3, for be the hang plate 14A of indentation bending along above-below direction.
In the present invention, also can fill the porous matter obturator of Raschig rings (raschig-ring) shape each other between (or 14A each other), thereby more carefully cut apart hang plate stream each other at hang plate 14.
In the present invention, also can be provided with along the collection mud rake device of cell body bottom surface rotation as above-mentioned shown in Figure 4.
In the above-described embodiment, the plan view shape of cell body 11 is circular, still also can be the above polygon of rectangle or pentagon, ellipse etc.
The present invention also can be used for the stillpot in the various processes except that being used for the draining processing.
