Abstract
The invention relates to a sewage discharging cofferdam. The sewage discharging cofferdam comprises a first baffle layer and a second baffle layer, wherein the first baffle layer is a rectangular plate and arranged about the outer side of a sludge tank; the second baffle layer is a saw-tooth shaped plate; a draining ditch is arranged between the second baffle layer and a wall body; the distance from the first baffle layer to the second baffle layer is 3 to 5cm. According to the sewage discharging cofferdam, the rectangular plate is additionally arranged between the saw-tooth shaped plate and the sludge tank, some sludge overflowed can fall between the first baffle layer and the second baffle layer, rather than directly flowing into the draining ditch when the water level raises to reach the height of the first baffle layer, and therefore, the secondary filtering of sludge can be realized, and the normal construction can be ensured.
Description
Technical field
The present invention relates to sewage treatment area, particularly a kind of effluent discharge cofferdam.
Background technology
Cofferdam refers in hydraulic engineering construction, for building permanent water conservancy projects, the provisional space enclosing structure of building, at present, the structure in effluent discharge cofferdam is as shown in Figure 1, comprise jagged baffle plate 3, described baffle plate 3 is enclosed to form sludge-tank 2, between external walls 1 and described baffle plate 3, be also provided with drainage channel 4, and the water in sludge-tank 2 is flowed out from the lower edge of zigzag baffle plate 3, and the mud in sludge-tank 2 is stopped by the zigzag of baffle plate 3, avoid flowing in drainage channel 4.But when water level rises too high, the mud having part floating flows out from zigzag baffle plate 3 under the drive of current, makes effluent discharge cofferdam not reach the effect of filter sludge, make mud flow in drainage channel 4, impact is constructed normally.
Summary of the invention
The invention provides a kind of effluent discharge cofferdam, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, the invention provides a kind of effluent discharge cofferdam, comprising first floor baffle plate and second layer baffle plate, described first floor baffle plate is rectangular slab, is around in outside sludge-tank; Described second layer baffle plate is serration plate, is provided with drainage channel between described second layer baffle plate and body of wall, and the distance between described first floor baffle plate and second layer baffle plate is 3 ~ 5cm.
Preferably, described first floor baffle plate is fixedly connected with described body of wall by angle bar.
Preferably, described sludge-tank is surrounded rectangle by described first floor baffle plate, and described angle bar is fixed on four angles place of rectangle.
Preferably, described first floor baffle plate and second layer baffle plate are made by PP material.
Preferably, the upper edge of described first floor baffle plate is higher than the upper edge of described second layer baffle plate.
Preferably, the difference in height between the upper edge of described first floor baffle plate and the upper edge of second layer baffle plate is 9 ~ 11cm.
Compared with prior art, effluent discharge cofferdam provided by the invention, comprises first floor baffle plate and second layer baffle plate, and described first floor baffle plate is rectangular slab, is around in outside sludge-tank; Described second layer baffle plate is serration plate, is provided with drainage channel between described second layer baffle plate and body of wall, and the distance between described first floor baffle plate and second layer baffle plate is 3 ~ 5cm.The present invention by setting up rectangular slab between serration plate and sludge-tank, when water level rises to the height higher than first floor baffle plate, the a small amount of mud overflowed can fall between first floor baffle plate and second layer baffle plate, can not flow directly in drainage channel, thus realize the secondary filter of mud, guarantee that construction is normal.

Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.It should be noted that, accompanying drawing of the present invention all adopts the form of simplification and all uses non-ratio accurately, only in order to object that is convenient, the aid illustration embodiment of the present invention lucidly.
Effluent discharge cofferdam provided by the invention, as shown in Figures 2 to 4, comprises first floor baffle plate 40 and second layer baffle plate 50, and described first floor baffle plate 40 is rectangular slab, is around in outside sludge-tank 20; Described second layer baffle plate 50 is serration plate, is provided with drainage channel 30 between described second layer baffle plate 50 and body of wall 10, and the distance L between described first floor baffle plate 40 and second layer baffle plate 50 is 3 ~ 5cm.The present invention by setting up rectangular slab between serration plate and sludge-tank 20, when water level rises to the height higher than first floor baffle plate 40, the a small amount of mud overflowed can fall between first floor baffle plate 40 and second layer baffle plate 50, can not flow directly in drainage channel 30, thus realize the secondary filter of mud, guarantee that construction is normal.Structure of the present invention is simple, not easily fault.
Preferably, please emphasis with reference to figure 2, described first floor baffle plate 40 is fixedly connected with described body of wall 10 by angle bar 41, particularly, in the present embodiment, described sludge-tank 20 is surrounded rectangle by described first floor baffle plate 40, and described angle bar 41 is fixed on four angles place of rectangle, topples over or crooked to avoid described first floor baffle plate 40.
Preferably, described first floor baffle plate 40 and second layer baffle plate 50 are made by PP material (polypropylene), and moisture-stable is cheap.
Preferably, please emphasis with reference to figure 3 and Fig. 4, the upper edge of described first floor baffle plate 40 higher than on described second layer baffle plate 50 along 51, that is, on first floor baffle plate 40 along the horizontal plane at place higher than on second layer baffle plate 50 along the horizontal plane at 51 places, avoid water level higher than first floor baffle plate 40, during lower than second layer baffle plate 50, first floor baffle plate 40 does not have filtration, preferably, difference in height between the upper edge of described first floor baffle plate 40 and the upper edge of second layer baffle plate 50 is 9 ~ 11cm, for Fig. 3 and Fig. 4, described first floor baffle plate 40 is H1 higher than the height of horizontal plane, second layer baffle plate 50 is H2 higher than the height of horizontal plane, then H1-H2=9 ~ 11cm, coordinate the distance L between first floor baffle plate 40 and second layer baffle plate 50, the two is made better to coordinate, mud is avoided to arrange outward, and then increase water quality.Then can carry out suitable adjustment according to the soil characteristic of locality as second layer baffle plate 50 is arranged along 51 and lower difference in height between 52 and angle, will not limit herein.
In sum, effluent discharge cofferdam provided by the invention, comprises first floor baffle plate 40 and second layer baffle plate 50, and described first floor baffle plate 40 is rectangular slab, is around in outside sludge-tank 20; Described second layer baffle plate 50 is serration plate, is provided with drainage channel 30 between described second layer baffle plate 50 and body of wall 10, and the distance between described first floor baffle plate 40 and second layer baffle plate 50 is 3 ~ 5cm.The present invention by setting up rectangular slab between serration plate and sludge-tank 20, when water level rises to the height higher than first floor baffle plate 40, the a small amount of mud overflowed can fall between first floor baffle plate 40 and second layer baffle plate 50, can not flow directly in drainage channel 30, thus realize the secondary filter of mud, guarantee that construction is normal.
